Breast cancer treatment may no longer be invasive in the future, avoiding psychological disasters. Comparative study of surgical margins in oncoplastic surgery and quadrantectomy in breast cancer. People are constantly stating that the human kind faces an unknown and threatening disease that is often severe and deadly, that health systems are overloaded, that there is no proven treatment to date, that vaccines will not be available in a short period of time, and that a situation like this has not occurred since the influenza pandemic in 1918. Provided we analyze the personal and the collective in our professional activities, how should we take care of ourselves? Thus, I will honestly and modestly give you my impressions on these matters, based on more than 40 years of profession, most of which practicing Mastology, and having the same experience in the pandemic as all of you, practically nil, apart from solely information with levels of evidence 5. It did not go well, to such an extent that he ended up in an intensive care unit as a victim of the disease and of his own strategy. In fact, I would like to use another term for it, also conceptualized as "gregarious behavior", which has to do with "the tendency to accept the reasoning or ideas of the majority as valid without analyzing whether they are logically correct". The best way to avoid the "herd effect" is to ask ourselves: What data are we basing ourselves on? I believe there is only one answer: to rationalize them, and to do it personally and intelligently, contemplating the dynamics of the pandemic and our reality at the moment of taking action. It should be noted that we are talking about oncological surgeries with or without previous neoadjuvant, favorable or advanced primary tumors that may include immediate reconstructions with expanders or prostheses or mastoplasty techniques that do not significantly increase surgical time nor increase the costs on essential supplies as well as any type of complication that needs to be resolved in the operating room. It makes no sense, at this time, to include treatments for benign pathologies, potential risk injuries, risk reduction surgeries, and delayed breast reconstructions. Although controversial, it is likely that the most prudent is take a "therapeutic time out" until the tests are negative and treatments can be started in a safer setting to avoid increased postoperative complications13. The fundamentals of providing patients with detailed information about the implications of the pandemic, the safety measures being taken by us, and the multidisciplinary decision-making and its reasons, are never to be forgotten, but rather to be reported into the clinical history and informed consent for signature. Within time, there are likely to be specific situations that will be analyzed legally in another context and the health team may find itself questioned for behaviors taken in an exceptional situation that generates this global health emergency. We should try to quickly return to normality, while still taking advantage of the lessons learned from our personal and group experiences, and to elaborate and define precise contingency plans in case of outbreaks, until we can achieve the longawaited goal of being able to immunize the entire population. Methods: Data from patients who underwent breastconserving surgery at the Hospital Geral de Caxias do Sul from January 2010 to December 2016 were analyzed. When comparing the tumor size in the anatomopathological examination and the size in ultrasonography, the mean differences accounted for 0. In Brazil, breast cancer mortality rates remain high, probably because the disease is still diagnosed in advanced stages. Population screening programs enabled more diagnoses of early-stage injuries, reducing death cases and promoting less aggressive surgeries1. In Caxias do Sul, in the state of Rio Grande do Sul, 46 cases of death from breast cancer were identified in 20163. Surgical treatment of breast cancer has undergone significant changes in recent decades, and breast-conserving surgery is the standard treatment for the early stages of the disease nowadays4. The radical mastectomy technique and its corresponding lymphatic drainage have been abandoned. The old Halstedian paradigm had been overcome, and conservative treatments, both for the excision of breast tissue and for the surgical approach of the armpit, have been increasingly employed5,6. The theory proposed by Bernard Fisher, which defines breast cancer as a systemic disease, was the basis for the development of breast-conserving surgery, providing a new and much-less aggressive perspective to surgical therapy 7-9. Veronesi, author of the renowned Milan I study, conducted between 1973 and 1980, analyzed 701 cases of early-stage breast cancer and randomized a group to undergo breast-conserving surgery with radiotherapy and another group with radical mastectomy10. For this surgical decision, tumor size is not an exclusive limiting factor of conservative surgery. Thus, breast-conserving surgery must always be the first option, provided that there are no contraindications to the procedure and that the tumor-tobreast volume ratio allows a surgical excision with satisfactory cosmetic outcome, according to oncological surgery concepts12. However, 4 to 20% of patients with early-stage breast cancer have local recurrence13. In addition, it is known that local recurrence increases the risk of distant recurrence15,16. Compromised surgical margin is the most common indication of reexcision after breast-conserving surgery, and this approach can lead to worse cosmetic results, increased risk of infection, higher costs, and delay in early adjuvant treatment1. However, the higher the volume of excised breast tissue, the lower the chances of obtaining more satisfactory cosmetic results12. Thus, considering the importance of the theme, the present study aimed to identify possible tendencies toward excision in healthy tissue beyond the ideal for oncological safety. The results observed here can be used to produce recommendations regarding the volume of tissue to be excised, aiming at cosmesis and aesthetics without impairing the oncological conduct for breast surgeries. The medical records of all patients who underwent breast-conserving surgery at the institution, from January 2010 to December 2016, were analyzed. Data on incomplete or dubious medical records, multicentric/ multifocal tumors, and patients submitted to surgical reintervention to enlarge margins were deemed reasons for exclusion from the study. In the analysis of surgical margin, the disease-free surgical margin was established as no ink on the tumor in cases of invasive tumors and margins greater than 2 mm in cases of tumors in situ. Moreover, multivariate backward linear logistic regression was used, associating the new variable with those previously reported. The other cases were excluded due to reexcisions, subsequent surgeries related to margin enlargement and multicentric or multifocal tumors, and those related to incomplete hospital data. In two cases, immunohistochemistry was not performed because they were nonepithelial tumors (1. In Table 2 and Graph 1, one may observe the distribution of tumors regarding the location in the breast and the mean of excised tissue. There was no statistical difference regarding tumor location and neither concerning the size of excised tissue in the surgical specimen. Table 3 and Graph 2 show the amount of excised tissue according to tumor size (in the anatomopathological examination). When comparing groups 1, 2, and 3 with group 4, there was an increase in the resected tissue in group 4 with statistical difference (p < 0. The development and evolution of the sentinel-lymph-node biopsy have positively affected the treatment of early-stage breast cancer. This procedure provides accurate diagnosis and prognostic information on patients with clinically negative lymph nodes and consists of a primary tool to guide surgical and adjuvant treatment. Since this study only analyzed breast-conserving surgeries and, therefore, patients with early-stage cancer, most patients did not present lymph node metastases. The findings of this research showed that the invasive ductal carcinoma of no special type corresponded to 56. Tests such as ultrasound, mammography, and magnetic resonance imaging, can be used for this purpose. When comparing tumor size in anatomopathological examinations and its size in ultrasonography, the mean difference of 0. It is clearly perceived that larger tumors dictate techniques that ultimately excise a greater amount of healthy tissue. When comparing groups 1, 2, and 3 with group 4, there was an increase in the size of excised tissue in group 4, with statistical difference (p< 0. This shows the clear tendency of surgeons for being more aggressive, even in conserving surgeries, when operating tumors whose mean diameter is greater than 3 cm. Taking this into consideration, patients with large tumors and small breasts are not likely to be submitted to breast-conserving surgery. Conversely, patients with more voluminous breasts consequently allow for greater tissue resection without major aesthetic impairments, which may justify our findings. The difference in the size of the total surgical specimen and the tumor size in the anatomopathological examination accounted for 5. When performing simple linear regression, it was observed that every 1 cm of tumor in the anatomopathological examination corresponds to 6. One possible reason for explaining excessive resection is the attempt to avoid subjecting the patient to a new surgical procedure to enlarge the margins, thus delaying the onset of adjuvant therapy. The use of frozen section histology assists in identifying margins compromised during the intraoperative period, avoiding excessive tissue excision or other surgery, providing more comfort and agility to the surgeons, since they will have information on enlargement of margins in appropriate time for doing it so, which also enhances the chances for surgeries seeking to conserve more healthy tissues. Nevertheless, this evaluation technique is not a standard procedure in all services, and some authors suggest that the tool may alter the pathological staging and is contraindicated in some cases, such as in small tumors.

Intraoperative assessment of margins in breast conserving therapy: a systematic review. Immunohistochemistry is a useful tool for defining the conducts toward the treatment of this disease. Conclusion: the triple negative molecular classification had the lowest overall survival and the greatest risk of recurrence. Breast cancer is the leading cause of death among women worldwide, accounting for 522,000 deaths in 2012 alone, equivalent to 14. The incidence of breast cancer has virtually increased worldwide, but in developed countries, this number has decreased in the last 10 years. Moreover, there has been a reduction in the death rate related to breast cancer due to adequate screening, early detection, and effective therapy2. Breast neoplasm does not indicate clinical uniformity and is characterized according to the morphology of the disease, thus existing different molecular forms and subtypes. Instead, it should be stated that breast cancer consists of a range of distinct neoplasms, which are all classified as breast cancer. These varied forms of the disease enable the evaluation and development of prognosis based on their evolution, making it possible to prescribe specific treatments according to the development and characteristics of each type. Immunohistochemical examination and anatomopathological analysis are paramount to define the disease approach and the prognosis of the patient. This technology has proved to be an important diagnosis tool, since it is a simple, practical, and versatile instrument4. It carries a considerable weight to decisions to be made at two moments during the course of the disease: first, at diagnosis and, secondly, at the definition of the treatment to be provided, being older age directly related to the worst outcome of breast cancer. These variations allow such tumors to present very different evolutions and biological behaviors, although they are all classified as breast cancer. Molecular classification allows identifying, with a high degree of accuracy, different types of the disease based on profiles. Thus, if a metastasis, whether distant or in a lymph node, is related to a certain tumor, it will present the same pattern of genes as if it were a sample of the main tumor13. Hence, lymph node invasion is a predictive factor for metastatic dissemination of breast cancer, contributing to a worsened evolution of the disease16. The most commonly used biomarkers in determining the treatment for breast cancer are estrogen and progesterone hormone receptors17. Mostly, it features negative hormone receptors and is related to a more aggressive type of the disease and worse prognosis. It is present in all active phases of the cell cycle, with the exception of the G0 phase20, being routinely evaluated in immunohistochemical tests for breast cancer as it is responsible for the differentiation between tumors of luminal types A and B. Immunophenotyping allowed the creation of gene expression profiling, which can be used to identify tumor evolution based on its molecular phenotype7. Based on this involvement, the breast volume that will be exposed to radiation in radiotherapy treatment can determine, in addition to whether there shall be lymph node clearance of the axillary region, which can cause important side and aesthetic effects on the quality of life of patients under treatment14. Then, each of the medical reports were read, leading to the selection of those in which the specimens derived from a surgical procedure of mastectomy or quadrantectomy. In some cases, there were divergences between the immunohistochemical classification of the biopsy and the subsequent analysis of the surgical specimen. On the other hand, the surgical specimen is analyzed in the so-called "hot spot," where the highest concentration of tumor cells is found. Death was measured and validated in the study only when it occurred within the institution and it was recorded in the electronic medical reports of each patient.
The presence of bacteremia in a wound infection patient may also explain the appearance of secondary bulbous lesions in some wound infection case descriptions (30 knee spasms causes discount urispas 200mg visa,31 muscle relaxant erectile dysfunction urispas 200mg otc,87) muscle relaxant 4211 v quality 200mg urispas. As seen in cases of primary septicemia spasms muscle twitching cheap 200 mg urispas overnight delivery, wound infection symptoms also include fever (75%) and chills (48%) spasms down legs when upright generic 200mg urispas free shipping. Other systemic symptoms such as hypotension muscle relaxant gel buy urispas 200 mg mastercard, nausea, and vomiting are present, but at a much lower frequency. However, the existence of preexisting disease is still important in that over 57% of all patients with wound infections summarized in Table 4 presented with some underlying disease such as liver disease, diabetes mellitus, or alcoholism. The average age of the 33 cases summarized in Table 4 is 41, of which 60% are males. It is possible that gastroenteritis patients may also have primary septicemia (3%) (Table 4) that is not documented by blood cultures (31). The mean incubation period is approximately 20 hours, and consumption of raw seafood, especially oysters (84. There have been many other reports of various clinical manifestations caused by this organism, including epiglottitis (93), pneumonia (85,94), endometriosis (95), meningitis (96), coinfections with other marine vibrios (97,98), sepsis from solid organ transplantation (99), osteomyelitis (100), and peritonitis (101), and a few cases have included histopathological findings (44,76). Most often, biotype 1 strains are the etiological agent responsible for the infections, and they usually occur as individual cases. However, biotype 3 has been reported to cause outbreaks of wound infections accompanied with bacteremia (37), and both biotype 1 and 2 strains can cause zoonotic outbreaks in cultured eels (33) and shrimp (40). However, the demographic data summarized in Table 4 may not reflect regional cultural eating and food-preparation practices. Does this lowered attack rate for males suggest the presence of cultural biases within this region, or are there unknown factors associated with biotype 3 virulence that led to the lower male infection rate? Additional studies are needed to further elucidate the pathogenesis, ecology, and factors responsible for the emergence of biotype 3 strains. A good geographic area to begin such investigations will be in countries that border the Mediterranean Sea. This threat is compounded further because the demand for seafood is increasing and is currently being met only through the harvest of seafoods from aquaculture and marine fish farming sources. All of these issues highlight the need for surveillance programs to monitor the health status of our seafoods. The organism has been isolated from plankton, shellfish, and water samples taken off the southeastern United States and Gulf Coast (57,111,112) and during the summer months, as far north in latitude as Portland, Maine (113), and Seattle, Washington (1). It has been cultured from waters and shellfish along the coasts of Puerto Rico (7), Taiwan (74,85,106,114), Hong Kong (115), India (116), Israel (137), Brazil (103,104), Romania (29), Korea (64), and Japan (79,117). Most of the reported cases involved were wound infections (64/141, 45%) and primary septicemia (62/14, 44%), followed by 6 (4%) cases of gastroenteritis. The preponderance of the reported gastroenteritis and wound infections occurred between May and August, and the majority of the primary septicemia cases occurred between May and November. Among the 300 reported hospitalizations due to Vibrio infections, 124 (41%) were because of V. It is interesting to note that both gastroenteritis and wound infections in the United States reported by Evans. Other biases may be related to how the oysters are harvested or human risk behavior patterns. Since shellfish, especially oysters, are seen as the primary vehicle for transmission of human V. It has been postulated that the protease may be responsible for the overwhelming immunosuppression that leads to or culminates in the inability of oyster hemocytes to kill and degrade intracellular P. This and other studies (127,128) suggest that the serine protease expressed by Perkinsus spp. More importantly, however, these studies stress the importance of verifying the health status of the oyster (or clam) as a host and transmission vehicle before attempting to assess the levels of vibrios in these economically important marine species. The consequence of this observation has public health significance, especially in understanding how V. The infectious dose capable of causing human disease is currently not known, but data from epidemiological studies clearly suggest that it may be fewer than 1000 organisms (130) and that the primary reservoir for V. However, shrimp, crabs, eels, and other fish (sashimi or sushi) have also been linked to disease (132). Because the epidemiology of this organism is so closely related to its ecology, Singer et al. Their results showed that extensive diversity was seen not only among Vibrio species, but also within the V. The eel isolate (15) from Japan and the clam isolate (16) from Oregon gave indistinguishable patterns. Note extensive differences in patterns signifies diversity among the genus Vibrio. Their results showed that a single individual oyster can harbor several different V. These problems have significantly hindered establishment of tolerance levels for V. This observation suggests that the strains were not of the same clone and that these findings supported an earlier hypothesis proposed by Rubin (136) and promulgated by Jackson et al. In the United States most cases occur either in the states bordering the Gulf of Mexico or the southeastern Atlantic coast or states that import oysters from these areas (31). However, reports of inland infections not solely attributed to the interstate transportation of seafood products have been reported (137). In Japan, a large percentage of cases occurs along the more temperate southwestern shores of the island chain. An increase in the total cell counts was not observed in such cultures, which indicates that the resuscitated cells came from the original cell population and was not due to growth of a few culturable cells. Characterization at the molecular level of the processes that lead to the nonculturable state, as well as those responsible for the genesis of resuscitation, is of considerable interest. This is not true, however, for those laboratories serving a coastal geographic area where the majority of cases are found and the vast plurality of clinical isolates are obtained from wound and blood specimens. Usually these specimens are free of other competing bacterial contaminants and are processed with no particular attention to the isolation of Vibrio species; most blood culture protocols that use blood agar plates (5% sheep erythrocytes mixed either in a trypticase soy agar or blood agar base) as the primary isolation medium are quite sufficient for recovery of V. However, unusual clinical sources do include urine and respiratory aspirates, which may have a plethora of competing microorganisms present (43). Many of the isolation techniques used in the clinical microbiological laboratories work well with V. However, there is considerable variation in growth, colonial morphology, and tinctorial appearances on these media, and V. The importance of obtaining rectal swabs or stool specimens prior to antibiotic therapy cannot be overemphasized in the clinical diagnosis of gastroenteritis, and whenever possible these specimens should be inoculated on isolation plates with minimal delay (43). It is recommended that buffered glycerol-saline not be used as a transport medium (43). However, tellurite-taurocholate-peptone broth has been extensively used with success as an enrichment transport medium at the International Center for Diarrheal Disease Research in Dhaka, Bangladesh (43). It is recommended that a cell suspension of the unknown isolate be made with added salt (1% NaCl or 20 marine salts) instead of the 0. However, comparative studies using all of the above described Vibrio isolation media and methods have not been done. Other rapid identification tests include a coagglutination assay using Staphylococcus aureus Cowan 1 cells armed with specific V. Animal studies have been helpful in reproducing some aspects of the disease syndromes, specifically wound and septicemia infections produced by V. However, it has not been correlative for assigning the infectious dose 50 for human infections, nor have animal studies been helpful in the study of intestinal disease caused by this microorganism. This invasion is either a consequence of the action of substances produced and released by the organism that digest tissue elements such as the extracellular matrix, an essential Copyright 2003 by Marcel Dekker, Inc. The extracellular matrix network is constructed by cells from secreted glycoproteins and proteoglycans. Elastinolytic Zinc Metalloproteases Metalloproteases, containing zinc as an essential metal ion for enzyme catalysis, are elaborated by many bacteria and are classified into 30 major families, which include the thermolysin-like, elastaselike, Serratia protease-like metalloproteases, and the neurotoxins of Clostridium tetani and Clostridium botulinum type B (211). It was later isolated and characterized by Kothary and Kreger (214), who assigned it a molecular weight of 50. Furthermore, it has been shown by a number of investigators that the metalloprotease possessed similar biological and immunological properties with the common zinc-metalloproteases expressed by V. The extracellular metalloprotease is thought to be important in aiding invasion of the bacterium into tissues by degrading elastin and collagen and may be responsible, at least in part, for the extensive tissue necrosis observed clinically during infections (217). The kinins bradykinin and lysylbradykinin are important mediators of inflammatory responses and are potent vasoactive peptides with wide-ranging properties, including the ability to (a) increase vascular permeability, (b) cause vasodilation, pain, and smooth muscle contraction, and (c) stimulate arachidonic acid metabolism. Activation occurs at sites of negatively charged molecules, such as collagen fibers associated with the interstitial tissue space (221). More research is needed to determine if the metalloprotease acts alone or in combination with other V. However, it is likely that the protease activation of the kinin system is involved in the intravascular dissemination. Capillary vessels are known to be stabilized by binding of the basal surface of vascular endothelial cells to the basement membrane. Alternatively, this may explain why the organism Copyright 2003 by Marcel Dekker, Inc. The protease digested all of the heme proteins tested and elicited the liberation of heme from the proteins. The lethality of inocula of the bacteria injected intraperitoneally (ip) was increased by concurrent injections (ip) of hemoglobin, methemoglobin, or hematin, but not by myoglobin. These investigators obtained similar results in mice with phenylhydrazine-induced hemoglobinemia. The C-terminal portion of the protease is thought to be essential for hemagglutination, binding to the erythrocyte membrane, and for proteolysis of membrane proteins (213). Cytotoxin/Hemolysin Kreger and Lockwood found in 1981 that there was an extracellular factor(s) in culture filtrates obtained from V. Later, Gray and Kreger (178) purified the cytolytic toxin and demonstrated that it was a heat labile, hydrophobic protein that was inhibited by large amounts of cholesterol, was partially inactivated by proteases and trypan blue, had a molecular weight of 56 kDa, possessed a single isotype with an isoelectric point of 7. These researchers also found that nonesterified cholesterol inactivated the cytolysin by converting active monomeric toxin into inactive aggregates of the 210 kDa oligomer. Together, these data support the hypothesis that the monomeric toxin binds to the cholesterol receptor as it associates with the erythrocytic membrane, then oligomerization occurs during lateral diffusion of the monomer in the fluid lipid bilayer. These data also suggest that the oligomer is not active unless it is already bound to the membrane. Gray and Kreger (238) showed that antitoxin antibodies were produced in vivo during the development of the disease in mice and in a human that survived V. In another study (239), these authors showed that a single intradermal injection of the purified toxin into the skin of mice produced extensive edema, caused the disorganization of collagen bundles, and generated an accumulation of cell debris and plasma proteins, which yielded extensive damage to fat, capillary endothelial, and muscle cells. A mild inflammatory cell infiltration confined to the subdermal area of the injection site was also induced. These data suggest that the hemolysin activates particulate guanylyl cyclase via hemolysin incorporation into the vascular smooth muscle cell membrane in cooperation with certain unidentified cytosolic component(s). Using ethyl methanesulfonate (243) transposon mutagenesis (244) and marker exchange to inactivate the 56 kDa cytolysin gene, both groups of investigators compared the virulence of hemolysin-negative mutants to fully virulent V. While these data suggest that the 56 kDa cytolysin may not be involved in the pathogenesis of V. However, the role of the two hemolysins, separately or together, is currently not known. Polysaccharide Capsule Capsules are produced by organisms in a variety of habitats, many of which are found in the marine environment (245). Expression is considered a basic cellular function, as judged by its early evolution and development (245). Pathogenic bacteria are often classified on the basis of the complex polysaccharides found on the surface, usually capsular polysaccharides or lipopolysaccharides. It is common in the clinical microbiology laboratory to use reactivity with antisera that specifically recognize these various cell surface carbohydrates for identification purposes. Amako and colleagues examined two clinical strains for the presence of a polysaccharide capsule by using a ruthenium red staining procedure. Figure 3 shows the ultrastructure of the capsule stained with Alcian blue and lysine in both encapsulated and unencapsulated phase variants. These studies further demonstrated that encapsulation correlated with colonial opacity and that variation in the opacity of colonies formed by the organism was accompanied by variation of capsular formation. Furthermore, encapsulated strains were also more resistant to the bactericidal action of human serum, possessed greater antiphagocytic activity, and were highly lethal for mice.

Across the Indian Ocean, within Ayurveda (a system of well-being and healing practised in India, and the cultural prism through which many people in India have traditionally viewed the person), understandings of self see the person in their wholeness and this, not disease, is the centre of ayurvedic medicine (Kakar 1982). This wholeness means that a person has not only three types of temperament with their 16 subtypes, but that these are enmeshed and entangled with the type of land on which the person grew up, with caste and lineage, and with food habits (to name but a few). The ayurvedic person lives within and partakes of different orders of being (physical, psychological, social, and metaphysical) all of which interrelate over fluid boundaries. In this way, personality psychology may operate to maintain the status quo, in part through promoting a form of individuality specific to particular cultures at particular times that leads us to believe that if all people are, for example, inherently greedy or biologically predisposed to be aggressive, then there is little point in re-imagining or reorganizing societal structures of inequality. Furthermore, through defining social problems or problems in living as private matters, the individual personality is constructed as the site for change and transformation, not society. This is to understand how personality theories may function as ideological constructions (Sloan 2009) as power moves through institutions and through our personalities, our intimate hopes and dreams. And, thus, as we come to experience ourselves through the capacities promoted, we become further tied to specific governmental and socioeconomic rationales (Dean 1999). The entangling of personality with fascist and racist rationales has been a key site of concern for personality theorists. Personalities for sale So what are the projects of government and ideologies that theories of personality may serve? For Craib (1998: 3), the personality, constantly worked on and questioned as part of a lifetime project, is embedded within the beginnings of industrialization, the development of the market economy, and its concomitant process of individualization. In experiencing alienation from their own self, people must `sell their "personality". Here we face the market as individual personalities (always readjusting, always flexible) (Craib 1998), and the market, as with all commodities, decides the value of our personalities, and perhaps, of the existence of personality itself. Pharmaceutical personalities the same market system that enables us to sell ourselves through our personalities also, by fixing us in a position of lack (always in need of improvement), enables us to buy our personalities, or to restore ourselves through a product. The marketing of psychotropic drugs both constitutes and relies upon an increasingly biologically coloured language of personhood, where we come to understand our sadness, through the language of dopamine levels, as a condition called depression amendable to drug treatment. Ultimately, we come to understand ourselves through the language of neurochemistry (Rose 2003). These are norms that seem connected to the unitary-bounded subject as a figure of autonomy privileged by the neoliberal (masculine) market economy that further disavows relationality and interdependency. Pathological personalities How can a product such as a drug restore our personalities? This rests on the assumption that personality lies in biology, that biology can become faulty, and that drugs can restore this personality. These personality groupings (as eccentric or erratic, borderline or schizoid) are umbrella terms that cover people who happen to have in common sets of behaviours that are considered antisocial, meaning that personality types are deduced from the behaviour that they are supposed to explain (Parker et al. Furthermore, such attempts to pinpoint distinct personality types, such as the psychopathic personality, often overlook the fact that what is considered to be antisocial is understood in specific social contexts that may change over time (Levenson 1992). And therefore, Through minimising the influence of the social, our culture has fostered a climate where the internal world of the individual has become the site where the problems of society are raised and where it is perceived they need to be resolved. This becomes particularly evident in the diagnosis of Borderline Personality Disorder, which is given to far more women than men, and often to women who have experienced childhood sexual abuse. If personality psychology often works to serve the status quo, and to encourage individuals to work on themselves instead of transforming society, then it becomes urgent to ask, `How can we theorize about personality in a manner that contributes to the construction of a humane and just society? Oullette (2008) suggests the answer to this may lie in the development of a critical personality psychology, to be achieved (an effort already partly underway) through a recasting of the history of personality theory to include: approaches and theorists usually overlooked or excluded (Teo 2005); scholarship outside of, and sometimes critical of, psychology; research on existential issues; narrative and historical research that understands people within a web of social relations; psychoanalytic approaches that understand people as socially enmeshed and not biologically determined; and work that seeks to understand people as embedded within often violent social contexts and power relations, for example, globalization, capitalism, and war. Similar fault lines of reformulation and transition have attended cross-national migrations of key psychological models. His clinical or critical interview, a flexible language and context-sensitive approach, was rendered into a standardized test apparatus that presumed a general, uniform sequence of ages and stages. English empiricism combined with an antipathy to theory, giving rise to a decontextualized (although, as we have seen, highly culturally inscribed) model of the subject, which then became the most compatible theoretical underpinning for a scientistic framework for legitimizing psychology (Norton 1981). The number of critical conceptual and historical analyses of developmental psychology. Gergen 1973; and Shotter 1980) enabled deconstructionist ideas to take root (notwithstanding the diverse claims structured within different varieties of constructionism, Danziger 1997). Armistead 1974) with reflections also in developmental psychology and education (Woodhead 1999). Volumes such as Richards (1974) provided wider interdisciplinary framing of such criticisms, and the follow-up text edited by Richards and Light (1986) consolidated this (and included a key chapter by Urwin 1986). Such intellectual work occurred alongside, and of course was influenced by, the current of political turmoil in the 1960s, including the rise of second wave feminism, and the black power and gay liberation movements, which were 71 Erica Burman marked by radical engagements with psychology via such publications as Rat, Myth and Magic and Humpty Dumpty. While Derridean analysis subverts and destabilizes the prevailing binaries structuring psychology as a prime exemplar of Western logocentrism (nature/ culture; female/male; passion/reason; black/white, etc. The new post-structuralist and deconstructionist approaches generated a new theoretical lexicon that specifically challenged prevailing psychological categories and frameworks. Significantly, the first theme identified for this project was `The critique of psychological theories and practices such as those of, or derived from, Piaget, Skinner, Chomsky, Bernstein and so forth. While Ideology & Consciousness was addressed to a wider remit of disciplines, the co-authored book Changing the Subject applied its critical perspectives specifically to psychology, the double meaning of its title encapsulating its argument of the need both to change the discipline of psychology and to formulate a materialist theory of subjectivity capable of social change (Henriques et al. Other important English-language accounts mobilizing historical analysis to critically re-read current theoretical presuppositions in 72 Developmental psychology psychology include Morss (1990) on the significance of the selective readings of Darwin which suppressed his focus on variation in favour of adaptation, and Steedman (1995) on how the trope of the child, and in particular the girlchild, came to personify interiority in Western culture. As already indicated, Marxism is a somewhat more hidden or controversial resource within such accounts, but is claimed by some, including Parker (2007) and Newman and Holzman (1993), and alluded to by Morss (1996). This was formulated contemporaneously in 1985 by both David Ingleby and Nikolas Rose to highlight the emergence of psychology within modernizing state apparatuses as an administrative technology of assessment and surveillance. On the other hand, there has been a longstanding and explicit feminist engagement with deconstruction, across disciplines as well as specifically in relation to psychology (Spivak 1990; Elam 1994). Feminists have long critiqued both the effects and terms of psychological models (of the child, of the family, etc. Walkerdine 1988) through to the radicalized presumptions of models of motherhood (Phoenix 1987, see also Burman 1996b). The longstanding and sustained character of feminist critiques of developmental psychology. It is significant that, in its early days, interest in discursive approaches was strongly associated with feminist interventions (see also Squire 1990; Burman 1990, 1996a). Psychoanalysis has been a third resource informing deconstructionist critiques of developmental psychology. Harris (1987) illustrates how a psychoanalytic understanding of mental functioning as surpassing consciousness not only challenges the cognitive underpinnings of rationality and puts into question the unitary character of the subject, but also highlights its links with industrial capitalism. While many deconstructionists were drawn to a Lacanian version of psychoanalysis (especially via its feminist rehabilitation, see Mitchell 1974; Grosz 1990), Bradley (1989, 1993) mobilised Kleinian theory to challenge the romance of the tranquil adorable baby and Urwin (1984/1998, 1986) offered both original syntheses of Lacanian and developmental perspectives and historical analyses of the relations between developmental psychology and psychoanalysis in Britain (Urwin and Sharland 1992). A frequent response to deconstructionist debates is to ask what should be put in place of the existing forms of developmental psychology. Nevertheless, without reconstructing or revising current models, deconstructing developmental psychology facilitates new agendas and alliances that prompt action and reflection, even if they refuse a reconstruction or rescue of the discipline. First, critical and deconstructionist debates in developmental psychology offer new possibilities of alliance and engagement with the emerging discipline of childhood studies that has been influential in Britain (James and Prout 1990; Jenks 2005). Heavily influenced by sociology, anthropology, and history, these debates have been marked by a strong antipathy to traditional developmental psychology, seen as the originator of a model of the child as deficient, and only concerned with what the child will become in later life. Critical developmental psychology approaches offer a new position for debate about the role and status of psychology within this important field, a further context for which has been the passing of the United Nations Convention on the Rights of the Child in 1989. Critical and deconstructionist ideas have also generated equivalent debates within education, both methodologically (Davies 1994; Lather 1999; Maclure 2005) and in terms of reinterpreting educational policy (Dahlberg et al. A third strand of inquiry invites a reconnection with the project envisaged by Riegel and others to move from local critique to international coalitions via addressing the political economy of development. For better or worse, current discourses of development connect children to national and international policy contexts, and criticisms of the limits of developmental thinking arising from economic development discussions are equally relevant to , and indeed extend the remit of critique within, developmental psychology (Sachs 1992; Mehmet 1995). The attention to colonial histories and current impacts of globalization has the merit of both connecting and topicalizing the diverse contexts of English-language developmental psychology, and connecting them with forms of developmental psychology. Developmental psychological knowledge is increasingly mobilized within transnational policies (Kumar and Burman 2009), and critical deconstructionist critiques are increasingly relevant (see also Burman 2008c). This would help to counter the covert gender blindness or at times explicit antifeminism of some childhood studies, which in turn warrants the longstanding feminist suspicion of child-focused interventions (as noted by Thorne 1987; Burman 2008d). Finally, a key challenge facing these deconstructionist approaches lies in resisting the revival of empiricism structured within the return of evolutionary psychology, which coincides with a global political context of economic recession and increasing emphasis on the unchangeability of social and individual conditions. In particular, new collusions between psychology and psychoanalysis are claimed to be warranted by new brain imaging technologies. Here deconstructionists need to turn their attentions to unravelling the mobilization of spurious methodological and theoretical claims linking attachment theory with the diagnosis and prediction of attachment disorders.

The kind of answer you will get to this question will depend on who you ask, the epistemological and theoretical perspective they hold, and it will, to a large extent, also depend on the region of the world they live in and the university or faculty they work in. Social psychology is not a unified discipline; there is not one social psychology, but many social psychologies. However, despite the diversity of the field today, the positivistic approach is more pervasive and dominant than other approaches. This is the perspective which is usually taught in standard psychology courses and textbooks in most parts of the world and it is this version of social psychology that informs various applied fields, of which organizational behaviour is one of the most popular. Organizational social psychology involves the application of social psychological theories and methods to understand, inform, and ultimately improve organizational practices. Organizations are ubiquitous to everyday life and are the main instruments of capitalism. As long as social psychology is deployed to solve management problems, a critique of social psychology must include a solid critique of organizational social psychology. This chapter will begin with a short historical overview, showing that social psychology was born out of an early interest in crowds or groups (Stainton Rogers 2011). It will then review the critiques made against mainstream social psychology, concentrating on the social identity perspective. The final part of the chapter will expand on the critical agenda by focusing on the applied field of organizational social psychology. The chapter will end by suggesting that organizational social psychology should renounce its fixation with groups within organizations and pay serious attention to critical management scholars who point to the relationship between broader societal ideologies and organizational life. A longstanding interest in groups Social psychology as we know it today began to appear between the late nineteenth century and early twentieth century. A group of people who contributed significantly to the establishment of social psychology as an independent field of study was the so-called folk psychologists. In the 1860s, Heymann Steinthal and Moritz Lazarus studied the psychology of ordinary people and collectives. Their work was driven by the basic principle that individuals who belong to the same group tend to think in a collective rather than an individual manner. These very early theorists and their interest in group and collective behaviour have been significant in the later development of social psychology. In 1908, the psychologist McDougall published what is often seen as one of the first social psychological textbooks in English (McDougall 1908/1960). Drawing on other social scientists, such as Le Bon, McDougall was significant in helping to establish social psychology as an independent discipline that would scientifically investigate crowds (Farr 1986). In the book the Group Mind (1920) he claimed that collectives that are relatively organized generate mental forces that are not exactly the same as the sum total of the attitudes of each individual group member. However, soon enough, the interest in group and collective phenomena began to diminish as the discipline focused more on the individual. Allport (1927) dismissed the group mind thesis by arguing that the locus of study in social psychology should be individuals, because it is individuals and not groups that act, think, and feel. In his book Social Psychology (1924), he proposed a behaviourist approach based on the experimental method and underpinned by the assumption that social psychology should be concerned with observable behaviour and not waste its energies on unobservable mental states. Kurt Lewin, who has been a prominent figure within the field of organizational behaviour, was interested in the impact of groups on perception and action. Lewin, alongside Muzafer Sherif, established experimental social psychology as we know it today (Stainton Rogers 2011). In the 1940s and the decades to follow, social psychological theories and approaches developed as a response to the sociopolitical issues of the time, such as the Holocaust. The experiments conducted by Muzafer Sherif, Solomon Ash, and later, Stanley Milgram and Philip Zimbardo explored issues of influence, conformity, and obedience, and could therefore be considered as critical in orientation (Hepburn 2003: 20). Criticizing the critical work Despite the critical potential of earlier work, the positivist perspective prevents social psychology from capturing real-world human experience. The first is the focus on science and the second is the social-individual division. Social psychologists tend to insist that their work is scientific, and they imply that experiments, or quantitative studies, should be prioritized over other research methods. In standard social psychology courses and textbooks, science is viewed as an alternative approach to dogma. Students are often taught that the scientific experimental method is the most suitable method, as it leads to objective generalizable knowledge about human behaviour. In search for generalizable results, experiments tend to take 80 Social psychology individuals away from their social context, which leads to a decontextualized understanding of mind and behaviour. A relatively large group of social psychologists today reject positivism and refuse to believe in generalizable statements.

A new pathway for the secretion of virulence factors by bacteria: the flagellar export apparatus functions as a protein-secretion system. This finding was viewed with skepticism because most samples of spiral organisms were obtained postmortem and contamination could therefore not be ruled out. Physicians and microbiologists believed that the stomach was sterile because of its acidic environment. In 1975, Steer (2) noted that spiral bacteria were in close proximity to the mucus-secreting cells of the gastric mucosa and that the bacteria possessed at least one flagellum. He emphasized that polymorphonuclear leukocytes migrated through the gastric mucosa, presumably in response to the bacteria. Endoscopic biopsy specimens were cultured but yielded only Pseudomonas aeruginosa (3). Some years later, Robin Warren and Barry Marshall at the Royal Perth Hospital, Australia, attempted to culture bacteria from gastric mucosal tissue specimens several times without success. Normally, the blood or chocolate agar plates were left in a microaerophilic environment for only 2 days, which was the standard technique for culture of Campylobacter jejuni. During the Easter weekend they had been left for 6 days and microbial colonies appeared. An article based on clinical observations, histological examination, and culture of antral specimens of 100 consecutive patients subjected to gastroscopy was published in the Lancet in 1984 (4). Interestingly, the authors predicted that the bacterium was an important factor in the etiology of chronic antral gastritis and, probably, also peptic ulceration. The described bacterium was regarded as an opportunistic pathogen attracted by changes in the gastric mucosa; ulcers were believed to be caused by acid, and they would heal if the acid could be suppressed. The new bacterium was referred to as a "campylobacter-like organism," and as a result its first official name was C. Nevertheless, the organism was considered too different taxonomically from other Campylobacter species to be included in the same genus; therefore, the new genus Helicobacter was created (5). Currently this genus contains about 18 species, most of which are of nonhuman origin (6). Sufficient data regarding this bacterium as an important human pathogen have gradually accumulated to convince even the most skeptical gastroenterologist. The fairly low number of genes is consistent with its restricted niche, few regulatory networks, and limited metabolic repertoire and biosynthetic capacity. The presence of homopolymeric tracts (polyC or polyG) and dinucleotide repeats. After a couple of weeks, the infection becomes asymptomatic but histological gastritis persists (14). The estimated risk of developing peptic ulcer disease during long-term follow-up of H. However, it remains unclear how or why ulcers develop, although variability among bacterial strain virulence and host defense, as well as environmental and dietary factors, may influence the pathogenesis. Acid secretion in response to a gastrin-releasing peptide is threefold higher in H. Antral levels of somatostatin, a potent inhibitor of gastrin secretion, are decreased in H. The elevated acid response to gastrin stimulation by the oxyntic mucosa in duodenal ulcer patients is due to the combination of a large parietal cell mass and the fact that these cells are not functionally impaired as long as the gastritis is virtually confined to the antral mucosa. The increased acid secretion results in an increased duodenal acid load with subsequent development of gastric metaplasia within the duodenal bulb, allowing H. The resulting duodenitis weakens the mucosa and predisposes to duodenal ulceration. A physiological decrease in gastric mucosal surface hydrophobicity with aging may contribute to the risk of ulcer development in the elderly population and may act synergistically with H. Phospholipase A 2 activity in gastric juice is substantially higher in duodenal ulcer patients than in those with healed ulcers after H. This observation suggests that the enzyme activity in gastric juice is low in the stomach of patients with normal or high acid production, but increases exponentially when the enzyme meets the neutral environment of the duodenal bulb. Active gastritis of the body mucosa with glandular atrophy is frequently detected in gastric Copyright 2003 by Marcel Dekker, Inc. Intestinal metaplasia, regarded as a precursor lesion for gastric adenocarcinoma, is more common in the antrum of these individuals than in duodenal ulcer patients (27). Atrophic Gastritis and Gastric Carcinoma Persistent gastric inflammation can lead to loss of the normal mucosal architecture with gradual disappearance of glands accompanied by increased interglandular connective tissue and reduced mucosal thickness. Thirty to 40 years of continuous inflammation may be necessary before moderate or severe atrophic gastritis develops. Importantly, atrophic body gastritis or multifocal atrophic gastritis has been reported to be associated with increased incidence of gastric adenocarcinoma (31,32). These studies are so compelling that the World Health Organization has classified H. In a prospective Japanese study, gastric cancer developed in approximately 3% of H. Among the infected patients, those with severe atrophy accompanying intestinal metaplasia, corpuspredominant gastritis, or both were at particularly high risk. When chronic atrophic gastritis becomes severe and extensive, the resulting hypochlorhydria favors bacterial overgrowth with the appearance of nitrites and N-nitroso compounds in the gastric lumen. Such compounds may induce epithelial dysplasia because of their mutagenic and carcinogenic properties (40). Interestingly, duodenal ulcer disease protects against, whereas gastric ulcer increases the risk of, subsequent gastric carcinoma (38,41). This disparity suggests that normal or high acid output associated with duodenal ulcer disease represents a defense factor against a malignant development and/or that the low acid output associated with gastric ulcer favors oncogenesis. Concurrent enteric helminth infestation attenuates Helicobacter-associated gastric atrophy in mice (42), which suggests that a concurrent parasitic burden may alter the immune response to H. High salt intake increases the access of carcinogens to proliferating epithelial stem cells in rat stomachs (42a) and may likewise increase the risk of gastric carcinoma in humans (43). Ascorbic acid (vitamin C) scavenges free oxygen radicals, and high dietary intake of this vitamin apparently protects against gastric carcinoma (46). The infection causes induction of reactive lymphoid follicles (49), which represent precursor lesions of gastric lymphomas. This progressive B-cell response to the bacteria depends on growth factors secreted by H. In westernized countries the prevalence of infection is considerably lower, especially in early childhood, but the infection rate increases with age (52). Because acquisition of new infections among adults in highly industrialized countries is quite low (1% per year) (53,54), H. People from industrialized countries who live in a developing country for a short time appear to be at particularly high risk of infection (57). Furthermore, municipal water supply has been claimed to be an important source of infection among children from families of both low and high socioeconomic status (61). Gastric carcinoma is the second most common fatal malignancy in the world and is the cause of more than 750,000 deaths annually (63). Prospective serological studies consistently show that there is roughly a threefold increased risk of gastric carcinoma in H. Because large variation exists in cancer risk among different populations, it is likely that genetic and/or environmental cofactors are important in modifying the consequences of H. Two categories of diagnostic methods can be distinguished: invasive tests detecting the microorganism in biopsy samples of the gastric mucosa obtained at endoscopy and so-called noninvasive tests performed without the need for endoscopy. The specificity and sensitivity and advantages and disadvantages of such methods have been extensively reviewed elsewhere (67). Briefly, fresh endoscopic biopsy specimens from the gastric antrum and body can be tested for the presence of H. The noninvasive methods include breath tests based on 13 C or 14 C urea detection. For the 14 C urea breath tests, urea enriched with 14 C is hydrolyzed in the stomach by H. The gas is absorbed at the intestinal level into the blood and is eliminated by the lungs in the exhaled air. Acid suppressive therapy may produce false-negative results; ideally, the test should be performed at least 2 weeks after the termination of such treatment. Noninvasive tests further include antibody determinations such as immunoblot analysis or the measurement of specific serum IgG and IgA antibodies with enzyme immunoassay, which can be performed with commercial kits (70).

We muscle relaxants knee pain discount 200 mg urispas fast delivery, as professionals working in breast radiology, are very happy to have the unique opportunity to share our working experience with you and explain the different aspects and developments of the wide spectrum of radiological methods for the diagnosis of breast cancer, including x-ray mammography, ultrasound, magnetic resonance imaging, and minimally invasive biopsies. In this book we have tried to give you a broad look at the wide world of breast imaging, from the different aspects and controversies regarding breast cancer screening programmes and radiation therapy, to important points for achieving high quality in imaging, diagnosis and reports. Finally, the book is concluded with an interview with a radiographer, representing one of the most important professions involved in medical imaging, responsible for performing safe and accurate imaging examinations, and generating the radiological images that are used by radiologists to diagnose diseases. We are delighted and proud to provide you with an insight into our daily work and expertise, and we hope that you will enjoy reading this book, improving your own knowledge of breast imaging, and getting to know the medical field that is dedicated to serving not only breast cancer patients, but all of the millions of women who undergo screening every year, throughout the world. The first attempts to search for and establish imaging examinations to visualise and diagnose the breast are more than hundred years old. Breast cancer is the most common malignant tumour that affects women all over the world. Roughly one woman in every eight suffers from breast cancer during her lifetime, and over the years, the average age of women affected by breast cancer has been decreasing. Most breast cancer patients are found in industrialised nations, but the graphy, and post therapy follow-up. Even oppo- benefit is unlikely and that a delayed benefit is what would be expected from periodic screening, but analysts 11 have the opportunity to begin annual screening between the ages of 40 and 44 years (qualified recommendation). Screening began in large numbers in the mid 1980s16 and soon after, the death rate began to fall. As more and more women have participated in screening it has continued to fall, so that now there are more than 35% fewer women dying of breast cancer each year. Therapy has improved, but in numerous studies where screening has been introduced into the general population where women have access to modern therapy, the major decline in deaths is among women with access to screening17. Although the trials, when analysed as planned, showed a significant benefit from screening women starting at the age of 40, analysts 7 once again ignored the science and to this day continue to claim the benefit is greater among older women, when the data do not support this. By grouping and averaging data, analysts made it appear as if there was a major change in the parameters of screening that happened at the age of 5012 when, in fact, none of the parameters change abruptly at age 50 or any other age. There are absolutely 13 made the scientifically unsupported claim that there was no benefit from screening women in their forties. By ignoring the science, these faulty analyses continue to guide other countries that find it expedient to wait until the age of 50 to encourage screening. Efforts to reduce access to screening included the false claim that screening was leading to earlier deaths for women no data to support the use of the age of 50 as a threshold for screening. It is a completely arbitrary choice, while the data show that lives are saved by screening starting at the age of 40. The randomised, controlled trials have proven this and observational studies have confirmed this, and this is why the age of 40 is the appropriate threshold. Much of the debate has been due to the publication of scientifically unsupportable concepts such as the fallacious suggestion that invasive breast cancers would disappear if left undetected by screening. In the 1950s and 1960s it was argued that breast cancer was systemic from the start and that early detection would have no benefit. In fact, the excess deaths were clearly due to an allocation imbalance due to an un-blinded allocation process. It was then argued that 2 it was not possible to screen women efficiently, but this was disproven by the Breast Cancer Detection Demonstration Project. Exaggerated concerns 3 claimed that the benefit was not as great for women in their forties. Computer modelling can be used to determine the importance of the time between screens (screening interval). Comparing women who are screened every year to those screened every two years shows, as would be expected, that the size and stage of the lesions is still important20 and that women screened with a shorter interval have more favourable tumour characteristics21,22. This is a ploy to dilute the results for the invasive lesions and should not be tolerated in publications. There is not enough space here to address all of the misinformation that has been promulgated concerning the suggestion by a few that there are thousands of invasive cancers diagnosed each year as a result of mammography screening that would regress and even disappear if left undetected by screening. The prestigious New England Journal of Medicine published a paper that should have never passed peer review that claimed that in 2008 alone there were 70,000 breast cancers that would have regressed or disappeared had they not been found by mammography. It is astonishing that mammography was blamed, since the authors actually had no idea which cancers were found by mammography since they had no idea which women actually had mammograms. In addition, they based their claims on, as they admitted, their "best guess" as to what the rate of cancers would have been had screening not begun in the 1980s! Based on the difference between the actual numbers of cancers diagnosed in 2008, and their "best guess" (which was lower), they claimed that the numbers of cancers above their guess must not be real and would have disappeared had they not been detected by screening. In fact, actual data (and not a "best guess") show that there has been no overdiagnosis of invasive cancers40. There are now two additional independent analyses of this paper that show that it is not scientifically supported41,42, yet it is repeatedly referenced in efforts to reduce access to screening. Clearly no one is forcing women to participate in screening and each woman (regardless of age) should make her own decision as to whether or not to participate. The decision should not be made by some politically driven panel of individuals who have no expertise or even experience in caring for women with breast cancer, who superimpose their own values on their guidelines and guess what women might or might not want to do. It should be based on accurate information so that each woman can decide for herself. There are indeed some identifiable women who are at higher risk of developing breast cancer. The fallacy of the argument for tailoring screening to patients at high risk is that this would mean that 75% of women who are diagnosed with breast cancer each year would not be screened. Welch argued for the insurance companies by suggesting that they should no longer be rated based on the participation of their insured women in screening. As has been seen in the United States, when screening is introduced into the general population, the death rate from breast cancer declines. Additional support for screening comes from evaluating women who have died from breast cancer. What they left out was that premature deaths cost society substantial amounts of money so that allowing women to die unnecessarily may not be such a money saver48. At most, 10% of women who are treated for breast cancer actually benefit from systemic treatment44. Preventing overdiagnosis and overtreatment As the value of mammography becomes clearer each year, the effort to reduce access has accelerated. Breast imaging experts in the United States recommend that women begin annual mammography screening at 40 (and earlier if they are at high risk). Recognising the importance of these recommendations and that lives are at stake, the Society of Breast Imaging has implemented several communications methods to ensure women are getting accurate information on breast cancer screening. Below we describe these tactics, which can also easily be employed for other breast cancer screening issues. Communicating with all these groups maximises the chances of the message getting through to the intended audience. When developing a campaign, you need to target a multitude of audiences (especially ones your main audience trusts) in order to realise your goals. In 2015, the American Cancer Society also released new guidelines that stated that women should begin annual mammography screening at age 45 and could transition to biennial screening at age 55. The release of these guidelines has compounded the confusion created by academic journal articles, which argued that annual mammograms lead to overdiagnosis During the last five years, breast imagers in the United States have been fighting an uphill battle to communicate the importance of life-saving mammographic screening to women. Despite the obvious advantages of mammography as a key component of preventive healthcare for women (breast cancer mortality in the United States has decreased by 35% since widespread screening mammography began in the 1980s), considerable variance in guidelines from researchers and stakeholders on when to start screening, and how frequently women should get mammograms, is leaving many women and their providers frustrated and confused. They are confused because they are receiving different recommedations from respectable experts and organisations. End the Confusion empowers women with clear and accurate information on mammography screening so they are prepared to make informed decisions after they have conversed with their healthcare providers. The Society of Breast Imaging does not want women to delay or forego screening mammography, as science shows that these actions can lead to increased mortality. The creation of a variety of materials is important because different stakeholders opt for different formats of information. To promote the campaign, we issued a press release, posted announcements on social media and encouraged our membership to inform their colleagues, especially those outside of radiology. Additionally, we sent promotional materials to stakeholder organisations for use within their networks. This proved to be a very successful tactic for getting the word out about End the Confusion and educating about the importance of mammographic screening. Since the site launched at the beginning of 2016, it has been visited 4,149 times (as per September 30, 2016). Panellists included experts in the field, as well as policymakers who champion this issue. With regard to breast cancer screening, reporters like to wade into the controversy instead of the science. However, creating a consistent level of awareness at local and national levels helps the media take notice and stay focused. To assist in these efforts, the Society provided talking points on the benefits of annual screening mammography. Social media is another tool that should be used when communicating about the importance of breast cancer screening. In order to maximise the impact of social media, it is important to tailor the posts to the medium. These actions may ultimately result in an increase in total followers and enhance the reach of your messages. From experience with our patients, breast mammography screening using the techniques described in this article. As new techniques are developed, they will be explored, and, if appropriate, disseminated (especially on social media). If you have questions about any of these tactics, including End the Confusion, please contact the Society of Breast Imaging at info@sbi-online. Most importantly, continue to discuss breast cancer screening with your patients, their providers and your colleagues outside of breast imaging, and provide them with appropriate information and recommendations. Multiple members and individuals have responded to social media posts, proving that the information has resonated with them. Breast cancer has ended the lives of too many women and has devastated their families. It remains the second leading cause of cancer deaths among women in the United States, and the death rate is highest among women imagers know that mammograms have detected cancers at an early stage when treatment is most effective. Patients are alive today because they practice the kind of preventive healthcare that is recommended by the Society of Breast Imaging, the American College of Radiology and other respected organisations. Although our efforts have been successful, it has not been an easy road, and the work is far from over. Women in the extreme density group are about four times more likely to develop breast cancer than women with fatty breasts. Dense breasts are more common in younger women and the breasts tend to become more fatty after menopause. Dense breast tissue reduces the effectiveness of mammography and increases the risk for developing breast cancer. In their early 40s, about 13% of women have extremely dense breasts and 44% have heterogeneously dense breasts; by the early 70s, 2% have extremely dense and 24% heterogeneously dense breasts. Women with extremely dense breasts are four times more likely than women with fatty breasts (A) to develop breast cancer but twice as likely as the average woman to develop breast cancer. When there is a more focal area of density in an otherwise low density mammogram (E, arrow), the density should be classified as heterogeneous rather than scattered. Because of this, women with dense tissue are at increased risk of having a cancer that presents due to symptoms, such as a lump, during the interval between recommended rounds of screening (one year in the U. These can represent up to one-third of the cancers diagnosed in women undergoing screening mammography. Advocacy efforts, generally spearheaded by women who were diagnosed with breast cancer after a negative screening mammogram12, have now resulted in 27 state laws7. The vast majority of cancers seen only on ultrasound are invasive and have not spread to lymph nodes. Slightly lower cancer detection rates have been observed with ultrasound performed by technologists. In the United States, the masking of cancer by dense tissue has become a political issue beginning with Connecticut, which became the first state to enact legislation requiring that women receive notification about breast density with their mammography est. Supplemental screening in addition to mammography is increasingly utilised for women with dense tissue. Detection of cancer may not be improved when the breast tissue is of this extreme density. Significantly improved cancer detection has been shown using 3D-mammography for women with heterogeneously dense breasts but not for women with extremely dense breasts.
