In order to achieve this objective: (1) Voluntary efforts to develop and expand both undergraduate and graduate programs to educate primary care physicians in increasing numbers should be continued sleep aid names discount 100 mg provigil free shipping. The establishment of appropriate administrative units for family practice should be encouraged insomnia ecards 100 mg provigil for sale. For each policy recommendation sleep aid video order provigil 100mg online, a succinct but cogent justification is provided to support the proposed action sleep aid 1 year old purchase provigil 100mg on-line. The new policy being proposed in recommendation 1 sleep aid patch generic 100mg provigil mastercard, below (shown in Appendix A) sleep aid visuals buy provigil 200mg line, incorporates relevant portions of the 21 existing policies that are recommended for rescission in recommendation 2. Appendix B shows a clean text version of the policy that is being proposed for adoption. The (relatively few) segments of policy that are not being retained in the proposed new policy are listed in Appendix D. Proposed language for adoption the costs of medical education should never be a barrier to pursuit of a career in medicine nor to the decision to practice in a given specialty. A sufficient breadth of financial aid opportunities should be available so that student specialty choice is not constrained based on the need for financial assistance. Encourage the expansion of National Institutes of Health programs that provide loan repayment in exchange for a commitment to conduct targeted research. Advocate for increased funding for the National Health Service Corps Loan Repayment Program to assure adequate funding of primary care within the National Health Service Corps, as well as to permit: (a) inclusion of all medical specialties in need, and (b) service in clinical settings that care for the underserved but are not necessarily located in health professions shortage areas. Encourage the National Health Service Corps to have repayment policies that are consistent with other federal loan forgiveness programs, thereby decreasing the amount of loans in default and increasing the number of physicians practicing in underserved areas. Advocate for federal legislation to support the creation of student loan savings accounts that allow for pre-tax dollars to be used to pay for student loans. Work with other concerned organizations to advocate for legislation and regulation that would result in favorable terms and conditions for borrowing and for loan repayment, and would permit 100% tax deductibility of interest on student loans and elimination of taxes on aid from service-based programs. Encourage the creation of privatesector financial aid programs with favorable interest rates or service obligations (such as community- or institution-based loan repayment programs or state medical society loan programs). Medical students should not be forced to jeopardize their education by the need to seek employment. Any decision on the part of the medical student to seek employment should take into account his/her academic situation. Medical schools should consider creating opportunities for paid employment for medical students. Support and encourage state medical societies to support further expansion of state loan repayment programs, particularly those that encompass physicians in non-primary care specialties. Take an active advocacy role during reauthorization of the Higher Education Act and similar legislation, to achieve the following goals: Original language 5. Continue to monitor the availability of and encourage medical schools and residency/fellowship programs to (a) provide financial aid opportunities and financial planning/debt management counseling to medical students and resident/fellow physicians; (b) work with key stakeholders to develop and disseminate standardized information on these topics for use by medical students, resident/fellow physicians, and young physicians; and (c) share innovative approaches with the medical education community. Medical schools should have programs in place to assist students to limit their debt. This includes making scholarship support available, counseling students about financial aid availability, and providing comprehensive debt management/financial planning counseling. Seek federal legislation or rule changes that would stop Medicare and Medicaid decertification of physicians due to unpaid student loan debt. Financial obligations, such as repayment of loans, and service obligations made in exchange for financial assistance, should be fulfilled. Collaborate with members of the Federation and the medical education community, and with other interested organizations, to address the cost of medical education and medical student debt through public- and private-sector advocacy. Vigorously advocate for and support expansion of and adequate funding for federal scholarship and loan repayment programs-such as those from the National Health Service Corps, Indian Health Service, Armed Forces, and Department of Veterans Affairs, and for comparable programs from states and the private sector-to promote practice in underserved areas, the military, and academic medicine or clinical research. Work to reinstate the economic hardship deferment qualification criterion known as the "20/220 pathway," and support alternate mechanisms that better address the financial needs of trainees with educational debt. Encourage the creation of private-sector financial aid programs with favorable interest rates or service obligations (such as community- or institution-based loan repayment programs or state medical society loan programs). Support stable funding for medical education programs to limit excessive tuition increases, and collect and disseminate information on medical school programs that cap medical education debt, including the types of debt management education that are provided. Work with state medical societies to advocate for the creation of either tuition caps or, if caps are not feasible, pre-defined tuition increases, so that medical students will be aware of their tuition and fee costs for the total period of their enrollment. Take an active advocacy role during reauthorization of the Higher Education Act and similar legislation, to achieve the following goals: (a) Eliminating the single holder rule; 14. Continue to work with state and county medical societies to advocate for adequate levels of medical school funding and to oppose legislative or regulatory provisions that would result in significant or unplanned tuition increases. Continue to study medical education financing, so as to identify long-term strategies to mitigate the debt burden of medical students, and monitor the short-and long-term impact of the economic environment on the availability of institutional and external sources of financial aid for medical students, as well as on choice of specialty and practice location. Collect and disseminate information on successful strategies used by medical schools to cap or reduce tuition. Financial aid opportunities, including scholarship and loan repayment programs, should be available so that individuals are not denied an opportunity to pursue medical education because of financial constraints. Medical schools should have policies and procedures in place that allow for flexible scheduling in the case that medical students encounter financial difficulties that can be remedied only by employment. There should be mechanisms to assist physicians who are experiencing hardship in meeting these obligations. The first phrase, "giving consideration to grace periods in renewals of federal loan programs," has been integrated into the new policy. Three of the 10 policies being addressed in this report are recommended for revision, as shown in Appendix A, with a clean text version shown in Appendix B: · · · H-310. Relevant aspects of the following four of these seven policies are recommended for a) incorporation into the three policies above and b) rescission: · · · · D-310. The frequency of athome call is not subject to the every-third-night limitation, but must satisfy the requirement for one-day-in-seven free of duty, when averaged over four weeks.

Formal educational activities must be scheduled and available within total duty clinical and educational work hour limits for all resident physicians. Formal educational activities must be scheduled and available within total duty hour limits for all resident physicians. Individual resident compensation and benefits must not be compromised or decreased as a result of changes in the graduate medical education system. An education that fosters professional development, takes priority over service, and leads to independent practice. With regard to education, residents and fellows should expect: (1) A graduate medical education experience that facilitates their professional and ethical development, to include regularly scheduled didactics for which they are released from clinical duties. Service obligations should not interfere with educational opportunities and clinical education should be given priority over service obligations; (2) Faculty who devote sufficient time to the educational program to fulfill their teaching and supervisory responsibilities; (3) Adequate clerical and clinical support services that minimize the extraneous, time-consuming work that draws attention from patient care issues and offers no educational value; (4) 24-hour per day access to information resources to educate themselves further about appropriate patient care; and (5) Resources that will allow them to pursue scholarly activities to include financial support and education leave to attend professional meetings. Appropriate supervision by qualified faculty with progressive resident responsibility toward independent practice. With regard to supervision, residents and fellows should expect supervision by physicians and non-physicians who are adequately qualified and which allows them to assume progressive responsibility appropriate to their level of education, competence, and experience. Original language (i) Is neither feasible nor desirable to develop universally applicable and precise requirements for supervision of residents. B) "the program must ensure that qualified faculty provide appropriate supervision of residents in patient care activities. With regard to the workplace, residents and fellows should have access to: (1) A safe workplace that enables them to fulfill their clinical duties and educational obligations; (2) Secure, clean, and comfortable on-call rooms and parking facilities which are secure and welllit; (3) Opportunities to participate on committees whose actions may affect their education, patient care, workplace, or contract.

Duty Clinical and educational work hours that protect patient safety and facilitate resident well-being and education. Graduate medical education enhances the quality of patient care in the institution sponsoring an accredited program. Resident physicians should learn to appreciate the importance of scholarly activities (a) Exemplary patient care is a vital component for any program of graduate medical education. Graduate medical education enhances the quality of patient care in the institution sponsoring an accredited residency program. Individual educational opportunities beyond the residency program should be provided for resident physicians who have an interest in, and show an aptitude for, academic and research pursuits. Faculty can comply with this principle through participation in scholarly meetings, journal club, lectures, and similar academic pursuits. Institutions must make every effort to allow residents already in the program to complete their education in the affected program. Programs must also make arrangements, when necessary, for the disposition of program files so that future confirmation of the completion of residency education is possible. Restrictive covenants must not be required of residents or applicants for residency education. Graduate medical education must include a formal educational component in addition to supervised clinical experience. Program directors must supervise and evaluate the clinical performance of resident physicians. The attending physician, or designate, must be available to the resident for consultation at all times. Residency program directors and faculty are responsible for evaluating and documenting the continuing development and competency of residents, as well as the readiness of residents to enter independent clinical practice upon completion of training. Program directors should also document any deficiency or concern that could interfere with the practice of medicine and which requires remediation, treatment, or removal from training. The frequency of at-home call is not subject to the everythird-night limitation, but must satisfy the requirement for one-day-in-seven free of duty, when averaged over four weeks. Each episode of this type of care, while it must be included in the 80-hour weekly maximum, will not initiate a new "off-duty period. Formal educational activities must be scheduled and available within total clinical and educational work hour limits for all resident physicians. Accurate, honest, and complete reporting of clinical and educational work hours is an essential element of medical professionalism and ethics. This includes disbursement of funds by direct deposit as opposed to a paper check and an online system of applying for funds; b) encourages a system of expedited repayment for purchases of $200 or less (or an equivalent institutional threshold), for example through payment directly from their residency and fellowship programs (in contrast to following traditional workflow for reimbursement); and c) encourages training programs to develop a budget and strategy for planned expenses versus unplanned expenses, where planned expenses should be estimated using historical data, and should include trainee reimbursements for items such as educational materials, attendance at conferences, and entertaining applicants. Payment in advance or within one month of document submission is strongly recommended. With regard to supervision, residents and fellows should expect supervision by physicians and nonphysicians who are adequately qualified and which allows them to assume progressive responsibility appropriate to their level of education, competence, and experience. It is neither feasible nor desirable to develop universally applicable and precise requirements for supervision of residents. Regular and timely feedback and evaluation based on valid assessments of resident performance. With regard to evaluation and assessment processes, residents and fellows should expect: (1) Timely and substantive evaluations during each rotation in which their competence is objectively assessed by faculty who have directly supervised their work; (2) To evaluate the faculty and the program confidentially and in writing at least once annually and expect that the training program will address deficiencies revealed by these evaluations in a timely fashion; (3) Access to their training file and to be made aware of the contents of their file on an annual basis; and (4) Training programs to complete primary verification/credentialing forms and recredentialing forms, apply all required signatures to the forms, and then have the forms permanently secured in their educational files at the completion of training or a period of training and, when requested by any organization involved in credentialing process, ensure the submission of those documents to the requesting organization within thirty days of the request. With regard to the workplace, residents and fellows should have access to: (1) A safe workplace that enables them to fulfill their clinical duties and educational obligations; (2) Secure, clean, and comfortable on-call rooms and parking facilities which are secure and well-lit; (3) Opportunities to participate on committees whose actions may affect their education, patient care, workplace, or contract. Information about the interviewing residency or fellowship program including a copy of the currently used contract clearly outlining the conditions for (re)appointment, details of remuneration, specific responsibilities including call obligations, and a detailed protocol for handling any grievance; and b. Compensation should reflect cost of living differences based on local economic factors, such as housing, transportation, and energy costs (which affect the purchasing power of wages), and include appropriate adjustments for changes in the cost of living. Quality and affordable comprehensive medical, mental health, dental, and vision care for residents and their families, as well as professional liability insurance and disability insurance to all residents for disabilities resulting from activities that are part of the educational program; b. An institutional written policy on and education in the signs of excessive fatigue, clinical depression, substance abuse and dependence, and other physician impairment issues; c.

In contrast to the posterior pituitary, which is derived from neuroectoderm and considered an extension of the brain, the anterior pituitary is derived from oral ectoderm on the roof of the mouth. Neither the anterior nor the posterior pituitary is derived from neural crest cells. I-cell disease is an autosomal recessive disorder that results from improper intracellular trafficking. This impaired trafficking results from the failure to add a mannose-6-phosphate residue to proteins that should be directed to lysosomes. On a cellular level, this results in the presence of numerous intracytoplasmic inclusions in cells of mesenchymal origin. These inclusions are membrane-bound vacuoles that are filled with fibrillogranular material, including a variety of lipids, mucopolysaccharides, and oligosaccharides. Be on the lookout for coarse facial features in a baby that is developmentally delayed and has restricted joint movement.

As seen in the image the presence of many lymphocytes and few Reed-Sternberg cells with collagen bands that circumscribe the lymphoid tissue into discrete nodules is consistent with the nodularsclerosing subtype of Hodgkin disease. This histologic picture also resembles the lymphocyte-predominance subtype, which is much less common but has an excellent prognosis; it also is found in women. Burkitt lymphoma is a non-Hodgkin type of lymphoma that predominantly is a B-lymphocyte lymphoma. It is associated with Epstein-Barr virus infections that can lead to activating mutations of c-myc caused by chromosomal translocation t(8;14). Histologically Burkitt lymphoma is characterized by sheets of lymphocytes with interspersed macrophages; this is referred to commonly as a "starry sky" appearance. This subtype is more common in men and more likely to be diagnosed at a later stage. If patients are exposed to blood that is incompatible with their own blood type, they may undergo an immune-mediated hemolytic anemia that could eventually lead to jaundice. By definition, chronic graft-versus-host disease occurs >100 days after transplant and can affect any organ system. Primary graft rejection occurs when neutrophil and platelet recovery does not occur in the usual time frame expected after transplantation, and is mediated by the recipient immune system against alloantigens expressed on donor stem cells. Patients in acute rejection do not present with dermatitis, hepatitis, and gastroenteritis as in graftversus-host disease. Hyperacute graft-versus-host disease is an entity that may occur within minutes of the time of engraftment. This is secondary to her dehydration (which is apparent by her symptoms of orthostatic hypotension). Her frequent emesis results in the loss of large quantities of protons from the body in the form of stomach acid. The loss of protons and build-up of bicarbonate in this patient causes metabolic alkalosis. Consumption of antacids can contribute to metabolic alkalosis but is not the cause in this patient. Dehydration causes an increase, not decrease, in hydrogen excretion in the distal tubule. Total bicarbonate reabsorption in the setting of metabolic alkalosis and volume depletion is likely to be reduced. Acutely, volume depletion will result in a net decrease in the filtered load of bicarbonate, despite an increase in bicarbonate concentration. In addition, increased plasma levels of bicarbonate will impair the ability of the proximal tubule cells to secrete acid necessary for bicarbonate reabsorption. Acute thrombosis due to coronary artery atherosclerosis results in myocyte necrosis of the ventricular wall. Patients with hyperprolactinemias typically have pituitary microadenomas that secrete prolactin. They present with visual field defects, nipple discharge bilaterally, and hypogonadism. Patients generally present in their 40s-50s with abdominal discomfort, hematuria, urinary tract infections, hypertension, and renal insufficiency. On gross pathology, the kidneys are enlarged and the normal parenchyma is replaced by dozens of cysts. Weak pulses in the lower extremities may be a sign of coarctation of the aorta, which is associated with Turner syndrome. Turner syndrome is the most common cause of primary amenorrhea, and patients present with short stature, webbed neck, and infantile genitalia. Ovaries are replaced with fibrous streaks, and appear small and fibrotic on ultrasound, as opposed to enlarged and cystic. The suspicion of child abuse arises when the injury and the story of the injury do not match. Children with osteogenesis imperfecta can present with spiral fractures as a result of seemingly benign accidents. Retinal hemorrhage and detachment also are seen frequently in cases of child abuse. If there is suspicion of retinal damage, the child should then see an ophthalmologist, but an urgent retinal examination is not necessary at this time. Although confronting the family and offering assistance may be well intended, it is not the appropriate course of action in this situation. Normal or even careless play is an insufficient explanation for a serious injury such as a spiral fracture of the femur. The paired, mesodermally derived organs that give rise to a bicornuate uterus are the mьllerian tubes, otherwise known as the paramesonephric ducts. These paired structures also develop into the fallopian tubes, and the upper, proximal portion of the vagina. These vestigial structures are most often found on the upper pole of the testes adjacent to the tunica vaginalis. The appendix epididymis is a small appendage on the head of the epididymis derived from the wolffian (mesonephric) duct, which is the genital duct that develops into the seminal vesicles, epididymis, ejaculatory duct, and vas deferens in the presence of androgens. The bulbourethral glands (also known as Cowper glands) are small exocrine glands found on the posterior and lateral aspect of the membranous urethra at the base of the penis. Skene glands (also known as paraurethral glands) are small glands found on the anterior wall of the vagina. Acyclovir is a guanosine analog used in the treatment of active herpesvirus infections. Zanamivir inhibits influenza neuraminidase, reducing the release of progeny virus. A 47-year-old man with a history of hyperparathyroidism presents to his physician because of a mass in his anterior neck. The patient reports that multiple family members have had "thyroid problems" in the past. As his condition worsens, he goes into respiratory failure and is now on a ventilator in a coma. The friend believes the patient would have wished for life support to be withdrawn. However, the patient had previously made a living will stipulating that all measures should be undertaken to maintain his life. A 50-year-old man comes to the physician because of abdominal fullness, fatigue, and weight loss but denies any fever or night sweats. Blood tests are positive for pancytopenia and on bone marrow aspiration predominant, large white cells demonstrate tartrate-resistant acid phosphatase activity. Laboratory analysis reveals normal liver markers and a creatine kinase of 3000 mg/dL. Which of the following medication(s) places this patient at the greatest risk of developing these adverse effects? A 42-year-old African-American woman with a history of sarcoidosis presents to a neurologist with a sudden onset of a unilateral inability to close the eye and decreased tearing. When she wrinkles her forehead or smiles, the affected side of her face remains relaxed. The muscles involved in this condition are derived from which of the following embryologic structures? The patient says he is concerned about his fatigue because he has a strong family history of cancer. He thinks that if his parents did not drink, smoke, and eat such poor diets they would have lived longer lives. Which of the following laboratory tests will most definitively determine the likely cause of his abnormal blood smear? While working in a microbiology laboratory, a researcher comes across an unlabeled cryotube in the 80° freezer. She deduces that it contains a strain of Escherichia coli and decides to test whether this strain has an intact lactose (lac) operon. After growing the cells in media containing both glucose and lactose, she observes that the b-galactosidase, encoded by the lac operon, is expressed. A mother brings her 2-month-old infant to the emergency department because of lethargy, failure to thrive, and a fever of 39. Physical examination reveals increased head circumference and prominent hepatosplenomegaly. On questioning, the boy reports that he last played in the woods two days before the rash began. A woman whose mother had cancer in both breasts develops breast cancer at age 26 years. What mechanism causes the genes that are most commonly tested for breast cancer to become tumorigenic? A 45-year-old woman with a long history of menstrual irregularities and infertility presents with complaints of worsening vision. A thorough review of systems reveals the presence of constipation, cold intolerance, and increased pigmentation of skin. A 12-year-old boy is brought to the emergency department suffering from an acute asthma attack. The intern reaches for a drug used for the chronic prevention of asthma exacerbations rather than a drug needed for this acute attack. She recently overcame her battle with alcoholism and says her next goal is to improve her "horrible diet. Laboratory studies are significant for a hemoglobin level of 8 g/dL and a mean corpuscular volume of 110 fL. Which of the following is the most accurate description of the function of folic acid? A 10-year-old boy with an X-linked immunodeficiency disease suffers from chronic recurrent gastrointestinal inflammation, which only moderately improves with cyclosporine therapy. The child has had previous laboratory evaluation that showed a negative reaction to the nitroblue tetrazolium test. A 3-year-old girl presents to the emergency department with two weeks of abdominal pain. The child says that her hands feel "funny," and she apparently has been stumbling, while walking, more frequently over the past few months. She says the baby is crying more than usual, is vomiting, and does not want to eat. A 68-year-old man suffered from a resting tremor and postural instability during his last five years of life. Mutations in which protein are genetically linked to the disease from which this man suffered? The tumor is centered at the pyloric zone just near the pyloric sphincter, on the lesser curvature. Which of the following signs and symptoms is most likely to be seen in this patient due to the mass effect of the tumor? A 35-year-old woman is brought to the emergency department because of diffuse muscle contractions. Her husband reports that last week she accidentally stuck her finger with a rusty nail. By which of the following mechanisms does this organism cause the symptoms associated with this disease? A 62-year-old man comes to the physician complaining of a skin rash that is extremely painful. Laboratory studies show elevated levels of testosterone, estrogen, and luteinizing hormone. A newborn initially is healthy but begins to have bilious emesis and fails to pass meconium during the first 48 hours of life. An emergent abdominal barium study is performed during this time and results are shown in the image.
Areas of palisading nuclei insomnia las vegas provigil 200 mg free shipping, or small fusiform cells with little cytoplasm and hyperchromic dense nuclei insomnia late pregnancy discount provigil 200 mg with visa, are characteristic of the disease sleep aid comparison generic provigil 100mg with mastercard. This patient is presenting with a ruptured ectopic pregnancy insomnia 36 hours discount provigil 200 mg without a prescription, which occurs when a blastocyst implants in an inappropriate location insomnia janet jackson buy 200 mg provigil with mastercard, most commonly the ampulla of the uterine tube insomnia problems generic provigil 200mg with mastercard. This typically presents as described in the question stem and constitutes a medical emergency. The most common risk factors are pelvic inflammatory disease, prior appendicitis or endometriosis, and previous abdominal surgery. This describes appropriate implantation of a blastocyst in a normal pregnancy and is therefore not directly associated with pathology. The occipital pole is the extreme posterior end of the occipital lobe, which houses the fibers that originate from the macula. Actinic keratosis is a premalignant lesion characterized by small, rough erythematous or brownish papules. It is commonly found in sun-exposed areas and is a precursor to squamous cell carcinoma. Dermatitis herpetiformis is a dermatologic condition associated with celiac disease that is characterized by pruritic papules and vesicles. Melanoma commonly presents with a dysplastic nevus that has undergone malignant transformation. However, histology would show tumor cells with large nuclei located directly below the epidermis. Seborrheic keratosis is a benign, flat, pigmented squamous proliferation with keratin cysts. Squamous cell carcinoma commonly appears on the hands and Test Block 3 · Answers 583 (in this case, left homonymous hemianopia) with sparing of central vision. A lesion in the optic chiasm would cause bitemporal hemianopia, not left homonymous hemianopia. Such lesions would cause contralateral superior quadrantanopia, or "pie in the sky" defects. A left retinal artery occlusion with sparing of the vessels supplying the macula could cause a hemianopia of the left eye, with macular sparing, but "left homonymous hemianopia" means that the left visual field of both eyes is defective. This answer choice does not support the macular sparing seen in our patient, a phenomenon caused by sparing of the occipital pole. This patient is most likely taking doxorubicin, which is associated with cardiotoxicity. The risk of heart failure is related to the current dose and cumulative dose administered to the patient. Chronic use of these agents can lead to congestive heart failure, as seen in this patient, particularly a dilated cardiomyopathy. Other adverse effects of doxorubicin include bone marrow suppression, local skin irritation, and red urine. Other cardiotoxic chemotherapeutic agents include fluorouracil, busulfan, cisplatin, mitoxantrone, and paclitaxel. Methotrexate inhibits dihydrofolate reductase in the S phase of the cell cycle, causing decreased synthesis of purines. Vincristine and vinblastine inhibit microtubule formation and prevent assembly of the mitotic spindle. Adverse effects include neurotoxicity, fever, vomiting, and (with vinblastine) severe bone marrow supression. Tamoxifen is a selective estrogen receptor modulator used as an adjuvant or preventative treatment for breast cancer. Adverse effects include endometrial hyperplasia and carcinoma, increased bone density, hypercoagulability, hot flashes, night sweats, and vaginal discharge. Kidney injury can take the form of a crystalluria that can lead to obstructive nephropathy or interstitial nephritis. It is used to treat candidiasis and cryptococcal meningitis and as prophylaxis against fungal infections in immunocompromised patients. Vulvovaginal candidiasis (a yeast infection) is associated with erythematous labia with shallow ulcerations, and tiny papules ("satellite lesions") beyond the main area of erythema. Simple vulvovaginal candidiasis is not accompanied by systemic symptoms such as fever and muscle aches. Metronidazole is used to treat infections caused by protozoa and anaerobic bacteria, including Trichomonas vaginalis and bacterial vaginosis. Infection with T vaginalis presents with a malodorous, frothy green discharge, vaginal pruritus, and erythema. Bacterial vaginosis, which is usually due to Gardnerella vaginalis infection, presents with perivaginal inflammation and irritation, dysuria, dyspareunia, and a grayish discharge with a "fishy" odor. Neither illness is usually accompanied by systemic symptoms or demarcated vaginal lesions as seen in the image. A syphilitic chancre, indicative of primary syphilis, is usually a solitary, painless, 1- to 2-cm papule with an indurated base. The oral form is associated with hemolytic anemia and headache, and the aerosolized form is associated with bronchospasm, rash, and conjunctival irritation. This patient is presenting with acute mental status changes and seizures secondary to severe hyponatremia. While it is certainly possible to become hyponatremic from excessive fluid intake (polydipsia), one would not expect to see a hyponatremia of this severity purely from drinking too much fluid. This would lead to water loss from the kidneys to compensate, and thus serum osmolality should not decrease. A new-onset seizure in an older adult always raises concern for a primary brain process, especially tumor. So while both are certainly possible, small cell lung cancer is much more likely in this patient. Mental status changes and seizures always raise concern for pathology occurring in the brain, in particular spaceoccupying lesions such as tumors. While squamous cell lung cancer is clearly associated with smoking, the paraneoplastic syndrome it presents with is usually the secretion of a parathyroid-like peptide, which causes signs and symptoms relating to the resultant hypercalcemia, such as fatigue, depression, muscle weakness, abdominal pain, nausea, and constipation. Degraded tetracycline is associated with Fanconi syndrome, a disorder of proximal tubule function that results in severe loss of protein, glucose, and essential minerals (especially calcium and magnesium). Patients present with symptoms of polydipsia, polyuria, and dehydration due to excess loss of water and solutes in their urine. Acute tubular necrosis is typically associated with hypoperfusion and is not associated with either Fanconi syndrome or tetracycline. Glomerulonephritis is most often caused by immune complex deposition and is not associated with either Fanconi syndrome or tetracycline. Kidney stones, commonly caused by hypercalciuria or infection, are not associated with either Fanconi syndrome or tetracycline. Renal papillary necrosis, often caused by diabetes or acute pyelone- phritis, is not associated with either Fanconi syndrome or tetracycline. Renal papillary necrosis can be caused by an overdose of analgesics such as aspirin, phenacetin, and acetaminophen. Necrosis results from a combination of decreased blood flow to the kidney, consumption of antioxidants, and subsequent oxidative damage. Histrionic personality disorder is one of the cluster B personality disorders (the "wild" group) that presents early in adulthood. It is best characterized as a pattern of excessive emotionality and attention seeking, and it is often accompanied by somatoform disorders (somatization is a process by which an individual uses his or her body or symptoms for a range of psychologic purposes and gains). An especially important characteristic to remember about histrionic personality disorder is the often overtly sexual nature of those affected. Type 1 bipolar disorder is characterized by manic episodes (periods of elevated or irritable mood that must last at least one week) as well as depressive syndromes and mixed syndromes. Sleep of sevennine hours per night is not usually consistent with a manic syndrome. Obsessive-compulsive personality disorder is characterized by an excessive preoccupation with control, order, and perfectionism. Paranoid personality disorder is characterized by the inherent belief that the world is a dangerous and threatening place. Upon meeting these individuals they often project strength and capability, and their distrust and suspiciousness of everyone is evident. Schizotypal personality disorder is characterized by interpersonal awkwardness, odd beliefs or magical thinking, and an eccentric appearance. Doxycycline can be used in the treatment of both syphilis and Chlamydia infection. When the dorsal columns are progressively demyelinated and the posterior nerve roots are sclerosed, the condition is referred to as tabes (Latin for "shriveled") dorsalis. These patients have decreased reflexes, decreased pain sensation, and decreased proprioception. The Romberg test is useful in this situation, because it can reveal a loss of proprioception when visual input is removed. Generally, the pathophysiology of syphilis is based on obliterative endarteritis; however, the precise cause of tabes dorsalis is not fully understood. Deficiency of sphingomyelinase in Niemann-Pick disease causes accumulation of sphingomyelin and cholesterol in parenchymal and reticuloendothelial cells. A positive inotropic agent would increase the contractility of the heart, causing both stroke volume and cardiac output to increase at any given end-diastolic volume. The Starling curve does not change its shape in response to inotropic agents; rather, it shifts to the left and upward. A shift down and to the left indicates a very low end-diastolic volume and cardiac output, which would occur in instances of decreased blood volume such as in severe hemorrhage. A shift of the Starling curve down and to the right would indicate an increasingly failing heart. A positive inotropic agent would affect the heart in the opposite manner and ameliorate the effects of heart failure. This often is called Pott disease, and the first symptom usually is pain rather than ataxia. Poliovirus has a specific trophism to motor neurons, and its lesions test Block 3 Test Block 3 · Answers 587 Answer F is incorrect. A shift up and to the right would indicate that there is an extremely high cardiac output along with a high enddiastolic volume. This would occur in the presence of an extremely high blood volume, not an increase in contractility. Anorexia nervosa is an eating disorder characterized by excessive dieting, excessive exercising, and body image disturbances. Physiologic consequences of the condition include severe weight loss, amenorrhea, lanugo (downy body hair on the trunk), melanosis coli (a blackened area on the colon as a result of laxative abuse), an increased risk of osteoporosis, mild anemia, leukopenia, and electrolyte disturbances. She also has symptoms of depression: sadness, anhedonia, feelings of guilt, and suicidal ideation. Although she may benefit from therapy and an antidepressant medication, her electrolyte disturbances put her at risk for seizures, and contraindicate the use of bupropion, which is an atypical antidepressant. Bupropion functions as a norepinephrine and dopamine reuptake inhibitor, and unlike other selective serotonin reuptake inhibitors, it does not carry sexual adverse effects. Buspirone is a serotonin 5-hydroxytryptamine1A-receptor partial agonist used to treat depression and generalized anxiety disorder. This drug does not cause addiction or sedation, and does not interact with alcohol. It is associated with a relatively high incidence of extrapyramidal symptoms, such as dystonia and ultimately tardive dyskinesia. The recipient of a bone marrow transplant undergoes myeloablative therapy before transplant, and therefore it is not expected that the patient would have significant numbers of T-lymphocytes. Hyperacute graft rejection is a potential side effect of solid organ transplant and is mediated by preformed recipient antibodies. Positive and negative controls are commonly used in the same batch to ensure that the assay was successful. This patient is exhibiting classic symptoms of Sheehan syndrome, or postpartum hypopituitarism. Although Sheehan syndrome is thought to result from infarction of the pituitary gland from severe bleeding and hypotension during delivery, most patients do not experience hypotension or severe blood loss in delivery. Patients exhibit signs of global hypopituitarism and often present complaining of fatigue, anorexia, poor lactation, and loss of pubic and axillary hair. Patients with hypothyroidism can present with weight gain, cold intolerance, weakness, myxedema and fatigue. Primary hypothyroidism can result from iodine deficiency, surgical removal of the thyroid gland, pharmacologic thyroid ablation, or autoimmune attack, as in Hashimoto thyroiditis. Patients can, therefore, present with galactorrhea in addition to normal symptoms of hypothyroidism, such as weight gain, cold intolerance, weakness, myxedema, and fatigue. Patients with Cushing syndrome present with hypertension, weight gain, moon facies, increased truncal obesity, hyperglycemia, amenorrhea, immune Full-length exams Answer D is incorrect. Both the positive and negative controls worked well, as three bands are clearly present in the positive control lane, and no bands are evident in the negative control lane. Vincristine and other vinca alkaloids block the polymerization of microtubules, thereby preventing the formation of a mitotic spindle. The mitotic spindle is necessary for mitosis; thus, vincristine is specific to the M phase. Vincristine prevents the formation of the mitotic spindle through the blockage of microtubule polymerization. This represents the hormone levels present in primary hyperthyroidism, such as Graves disease, which results from stimulation of the thyroid gland by autoimmune antibodies. Symptoms of hyperthyroidism include heat intolerance, hyperactivity, weight loss, heart palpitations, diarrhea, increased reflexes, and exophthalmia. This patient has thymic aplasia (DiGeorge syndrome), in which the third and fourth pharyngeal pouches, and thus the thymus and parathyroid glands, fail to develop.
