These observations may be accompanied by confirmatory tests providing evidence of absence of cerebral hemispheric and upper brainstem function medicine 257 40mg citalopram, discussed below medicine ball abs buy citalopram 40mg with visa. In the period immediately following brain death medications jamaica buy 40mg citalopram with amex, the agonal release of adrenal catecholamines into the bloodstream may cause the pupils to become dilated symptoms with twins cheap 20mg citalopram visa. However, as the catecholamines are metabolized, the pupils return to a midposition. Hence, although the Harvard criteria required that the pupils be dilated as well as fixed, midposition fixed pupils are a more reliable sign of brain death, and failure of the pupils to return to midposition within several hours after brain death suggests residual sympathetic activation arising from the medulla. Neuromuscular blocking agents, however, should not affect pupillary size as nicotinic receptors are not present in the iris. One recent report has described an unusual observation of persistent asynchronous lightindependent pupillary activity (2. In patients in whom a history of possible trauma has not been eliminated, cervical spine injury must be excluded before testing oculocephalic responses. Care should be taken when performing cold water caloric testing to ensure that the stimulus reaches the tympanic membrane. Up to 1 minute of observation for eye movement should follow irrigation of each side with a 5-minute interval between each examination. The absence of a gag reflex should be tested by stimulation of the posterior pharynx, but may be difficult to elicit or observe in intubated patients. Additionally, response to noxious stimulation of the supraorbital nerve or temporomandibular joints11 should be tested during the examination. However, spinal reflex activity, in response to both noxious stimuli and tendon stretch, often can be shown to persist in experimental animals whose brains have been destroyed above the spinal level. The same reflexes can be found in the isolated spinal cord of humans following high spinal cord transection. A variety of unusual, spinally mediated movements can appear and persist for prolonged periods during artificial life support. It is important to note that spontaneous hypoxic or hypotensive events and apnea testing may precipitate these movements. As a result, such patients may be apneic for several minutes when removed from the ventilator, even if they have a structurally normal brainstem. To test brainstem function without concurrently inducing severe hypoxemia under such circumstances, respiratory activity should be tested by the technique of apneic oxygenation. With this technique, the patient is ventilated with 100% oxygen for a period of 10 to 20 minutes. The respirator is then disconnected to avoid false readings and oxygen is delivered through a catheter to the trachea at a rate of about 6 L/minute. The resulting tension of oxygen in the alveoli will remain high enough to maintain the arterial blood at adequate oxygen tensions for as long as an hour or more. Chronic pulmonary disease producing baseline hypercapnia may complicate the apnea testing and can be identified in initial blood gas examination by elevated serum bicarbonate concentration. During testing the patient should be observed for respiration defined as abdominal or chest excursions. After 8 minutes have elapsed, arterial blood gases should be sampled and the ventilator reconnected. Alternatively, if respiratory movements are seen, the test is negative and retesting at a later time is indicated. Prior to initiating apnea testing the absence of brainstem reflexes should have already been established. Hypothermia must be excluded; if core temperatures obtained by rectal measurement are below 36. A systolic blood pressure of greater than 90 mm Hg should be maintained using dopamine infusion if required. If hypotension (systolic blood pressure less than 90 mm Hg) arises during the examination, blood samples should be promptly drawn and the ventilator immediately reconnected. As diabetes insipidus is a common complication of severe brain injuries, this should be recognized if present and managed. Accordingly, efforts should ensure euvolemia or positive fluid balance for at least 6 hours prior to testing. Confirmatory Laboratory Tests and Diagnosis When the clinical examination is unequivocal, no additional tests are required. This procedure also has the advantage, when positive, of establishing a structural cause of brain death. In cases where the original cause of cerebral injury is not known, the absence of blood flow provides the crucial information necessary to declare brain death with certainty. The second, and probably more common, occurrence is a progressive loss of blood flow that accompanies death of the brain. As the dead tissue becomes edematous, the local tissue pressure exceeds capillary perfusion pressure, resulting in stasis of blood flow, further edema, and further vascular stasis. If the respiratory and cardiovascular systems are kept functioning for many hours or days after brain circulation has ceased, the brain undergoes autolysis at body temperature, resulting in a soft and necrotic organ at autopsy referred to by pathologists as a ``respirator brain. Two types of abnormalities have been correlated with brain death: (1) an absence of diastolic or reverberating flow, indicating the loss of arterial contractive force, and (2) the appearance of small systolic peaks early in systole, indicative of high vascular resistance. The technique is limited by the requirement of skill in the operation of the equipment and has a potentially high error rate for missing blood flow because of incorrect placement of the transducer. Recent studies report a sensitivity of 77% and a specificity of 100% of diagnosing brain death if both the middle cerebral arteries and the basilar artery were insonated; sensitivity improved with increasing time of evaluation following initial clinical diagnosis. The test can be done at the bedside using a portable gamma camera after injection of isotope, which should be used within 30 minutes after its reconstitution. A static image of 500,000 counts obtained at several time points is recommended (taken immediately, 30 to 60 minutes after injection, and at 2 hours past injection time25). Cerebral metabolism in brain death measured by 18F-fluorodeoxyglucose-positron emission tomography demonstrating the unequivocal finding of an ``empty skull. Moreover, technical recording errors can simulate electrocerebral activity as well as electrocerebral inactivity and several ostensibly isoelectric tracings must be discarded because of faulty technique. After depressive drug poisoning, total loss of cerebral hemispheric function and electrocerebral silence have been observed for as long as 50 hours with full clinical recovery. Physicians have appropriately raised questions as to whether a few fragments of cerebral electrical activity mean anything when they arise from a body that has totally lost all capacity for the brain to regulate internal and external homeostasis. Death is a process in which different organs and parts of organs lose their living properties at widely varying rates. Death of the brain occurs when the organ irreversibly loses its capacity to maintain the vital integrative functions regulated by the vegetative and consciousness-mediating centers of the brainstem. Test of integrity of recording system by deliberate creation of electrode artifact by manipulation 4. No activity with a sensitivity increased to at least 2 mV/mm for 30 minutes with inclusion of appropriate calibrations 6. Recording with an electrocardiogram and other monitoring devices, such as a pair of electrodes on the dorsum of the right hand, to detect extracerebral responses 8. Given such evidence, when and how is one to decide in such cases that anesthesia has slipped into death and further cardiopulmonary support is futile Unfortunately, few empirical data provide an answer to the question, particularly if faced with the complex problem of a patient with a coma of undetermined origin. In such cases, the combination of a prolonged period of observation (more than 24 hours), loss of cerebral perfusion, and exclusion of other potential confounds is required. A general guideline proposed for known intoxications is the following: an observation period greater than four times the half-life of the pharmacologic agent should be used. Pitfalls in the Diagnosis of Brain Death Potential pitfalls accompany the diagnosis of brain death, particularly when coma occurs in hospitalized patients or those who have been chronically ill. Almost none of these will lead to serious error in diagnosis if the examining physician is aware of them and attends to them when examining individual patients who are considered brain dead.
Onset of seizures due to subarachnoid hemorrhage or subdural hemorrhage is usually the second or third day of life symptoms 5dpo purchase 40 mg citalopram with visa, while those due to germinal matrix-intraventricular hemorrhage present after the third day (2) medicine emoji quality citalopram 20 mg. Congenital infections with viruses (cytomegalovirus treatment for shingles purchase citalopram 40mg amex, rubella 5 medications related to the lymphatic system discount citalopram 40mg with mastercard, herpes, and others) or toxoplasmosis can cause severe encephalopathic disease. Seizures also often occur in neonates with acute intracranial bacterial infections, most commonly Escherichia coli and group B streptococcal meningitis. Metabolic disturbances such as hypoglycemia, hypocalcemia, and hypomagnesemia are associated with neonatal seizures. Newborn infants who are premature and infants of diabetic mothers (large for gestational age, or small for gestational age) are most at risk for hypoglycemia. Those infants who are of low birth weight, born to diabetic mothers, or who have suffered hypoxic-ischemic injury are also at risk for hypocalcemia. Other metabolic abnormalities associated with seizures include local anesthetic intoxication, hyponatremia, and inborn errors of metabolism (2,5). Diagnostic evaluation includes glucose, electrolytes, calcium, magnesium, and phosphorus in order to identify an immediately correctable metabolic condition. Lesions of hypoxic-ischemic injury can be identified within the first 2-3 days after the asphyxial event (6). Treatment of neonatal seizures should focus on the primary etiology as well as direct seizure control. Phenobarbital is often used as the first line anticonvulsant, followed by phenytoin and lorazepam. Prognosis varies as a function of primary etiology and gestational age of the infant. Infants with a normal background activity are less likely to have neurological sequelae as Page - 102 opposed to those with moderate to severe abnormalities such as burst-suppression pattern, voltage suppression, and electrocerebral silence (2). Does the onset of neonatal seizures correlate with the timing of fetal neurologic injury Neonatal seizures associated with cerebral lesions shown by magnetic resonance imaging. Intrapartum medications included 3 doses of butorphanol (narcotic opioid analgesic). She is centrally pink with persistent grunting, shallow respirations, and lethargy. The chest x-ray is rotated with fluid in the right fissure, diffuse streakiness on the left, and a normal cardiac silhouette. The evaluation and management of the neonate at risk for sepsis is potentially a source of frustration for students and practitioners. The convention in the past has often been to evaluate and empirically treat all neonates felt to be at significant risk, especially as relates to maternal factors and the receipt of maternal antibiotics in labor. Due to evolutions in health care and the advent of intrapartum prophylaxis for group B streptococcal sepsis (mothers are routinely screened for group B strep and if found to be positive, they are given ampicillin prior to delivery), more attention has come to focus (very appropriately) on the clinical evaluation of the infant as a major part of the decision to evaluate and treat with antibiotics. This factor; however, remains fraught with a degree of uncertainty related to the nonspecific manifestations of infection in the newborn, the sometimes rapid progression of sepsis in the newborn, and the lack of laboratory tools which have high positive predictive accuracy. The approach in this section of neonatal sepsis will be to: 1) incorporate the evolutionary changes in management which are based on more recent evidence; 2) to emphasize the lack of a gold standard underlying the variations in practice. The information upon which former standard practice is based is also provided throughout the chapter. These are necessary and basic to understanding the problem of neonatal sepsis and perinatal infections. Common bacterial and viral infectious agents causing sepsis (or something similar to sepsis): E. The most important risk factors for neonatal sepsis: Prematurity Untreated maternal chorioamnionitis. There are still many unknowns in neonatal sepsis which continue to elude us, and compel the diagnosis of neonatal infection to be made clinically more often than not. Will ampicillin resistant organisms be seen with more use of intrapartum ampicillin prophylaxis Does intrapartum treatment of the mother for chorioamnionitis also treat the fetus effectively This intention paradoxically results in a more "aggressive" approach to the patient in terms of tests and/or treatment. This paradox is underscored by the lack of a gold standard for diagnosing sepsis in the newborn, and complicated by the recent increase of intrapartum antibiotics prescribed to women in labor. For a totally asymptomatic infant with high risk factors, none of the steps might be elected (practice variation). This is based on the premise that the clinical appearance and serial monitoring of the infant is just as accurate as any laboratory test for indicating the presence of infection, given any set of risk factors in an infant with a relatively normal exam. This wide variation of practice suggests that the unknowns in neonatal sepsis (see above) are quite important to practical management. This may lead one to be more or less restrictive in practice, and requires one to have thorough knowledge of the predictive accuracy of the objective tools available in the assessment of neonatal sepsis. From an outcomes point of view, one would expect that if certain practices were inappropriate, there would be a higher rate of readmission within two weeks of discharge from the normal nursery for those regimens which were "least restrictive. The highest degree of controversy surrounds the group of infants who are asymptomatic with some risk factors for sepsis, especially those whose mothers received intrapartum antibiotics. In these infants, there is the fear of partially treated sepsis, prompting evaluation and treatment of these infants based on their risk factors and discounting the maternal antibiotics. However, the asymptomatic state could also be interpreted as adequate prophylactic treatment for neonatal bacteremia. They concluded that there is no consensus regarding management of pretreated, healthy appearing, term gestation neonates (8). In contrast, Teji et al (1994) surveyed neonatologists in Midwestern states of the U. One hundred thirty seven responses were received and prematurity and severity of maternal illness significantly influenced the decision to treat empirically, irrespective of screening test results (9). More recently, Eichenwald (1997) has suggested a very reasonable scheme for evaluation of the asymptomatic term infant, based on a protocol developed by the Joint Program in Neonatology in Boston (Table 8) (10). However, the question persists and evolves regarding the benefits and risks of routine therapy of high risk neonates vs. Management of asymptomatic term infants with risk factors for infection for term, well appearing infants with maternal antibiotics given in labor. They concluded that their data support restricting a full course of antibiotic treatment to only those patients with clinical or laboratory signs of sepsis (18%) (5). Escobar et al (2000) reported on a large population of newborns in the Kaiser system of whom 15% were evaluated for sepsis (4). They concluded that evidence based observation and treatment protocols could be defined, based on a limited set of predictors: maternal fever, chorioamnionitis, initial neonatal examination, and absolute neutrophil count (4). Ultimately, each practitioner must determine the degree of risk or uncertainty that he or she can accept on the basis of clinical and institutional experience. Risk factors: Prematurity, chorioamnionitis, prolonged rupture of membranes, maternal fever, fetal tachycardia and depression at birth. For premature infants in whom the physical exam may be more equivocal and whose prematurity constitutes an additional risk factor, the threshold for a full sepsis evaluation and antibiotic treatment is much lower. For the case presented at the beginning of this chapter, you are asked to consult on this case. Is the volume of blood obtained for the blood culture important to the culture being positive or negative Is there good evidence that treatment of maternal chorioamnionitis prior to delivery significantly reduces the risk of neonatal infection Does prophylaxis for group B strep infection alter the time course of early onset group B streptococcal sepsis if prophylaxis is ineffective What is the incidence of neonatal sepsis and what is the mortality from neonatal sepsis Outcome of term gestation neonates whose mothers received intrapartum antibiotics for suspected chorioamnionitis.
However treatment mrsa order 40mg citalopram with visa, screening women with a strong family history of breast cancer is recommended when genetic counseling is available medications you cant crush buy citalopram 40mg low cost. Breast quadrants this illustration shows the quadrants of the right breast and the Tail of Spence symptoms 10dpo generic citalopram 20 mg overnight delivery. Invasive tumor cells medications used to treat anxiety buy 20 mg citalopram fast delivery, which make up 80% of all breast cancers, have "invaded" or spread to the surrounding breast tissue. Inspection may reveal nipple retraction, scaly skin around the nipple, skin changes, erythema, and clear, milky, or bloody discharge. Palpation of the cervical supraclavicular and axillary nodes may reveal lumps or enlargement. Although growth rates vary, a lump may take up to 8 years to become palpable at (1 cm). Breast cancers can spread via the lymphatic system and bloodstream, through the right side of the heart to the lungs and, eventually, to the other breast, chest wall, liver, bone, and brain. Types of breast cancer the illustrations below show ductal carcinoma in situ and infiltrating or invasive ductal carcinoma. Lumpectomy Through a small incision, the surgeon removes the tumor, surrounding tissue and, possibly, nearby lymph nodes. Studies show that lumpectomy and radiation are as effective as mastectomy in early-stage breast cancer. Partial mastectomy the surgeon removes the tumor along with a wedge of normal tissue, skin, fascia, and axillary lymph nodes. Radiation therapy or chemotherapy is usually used after surgery to destroy undetected disease in other breast areas. This procedure is used if the cancer is confined to breast tissue and no lymph node involvement is detected. Modified radical mastectomy the surgeon removes the entire breast, axillary lymph nodes, and the lining that covers the chest muscles. If the lymph nodes contain cancer cells, radiation therapy and chemotherapy follow. Modified radical mastectomy has largely replaced the radical mastectomy because it preserves the pectoral muscles. Before or after tumor removal, radiation therapy may be used to destroy a small, early-stage tumor without distant metastasis. Preoperative radiation therapy to the breast also "sterilizes" the area, making the tumor more manageable surgically, especially in inflammatory breast cancer. Chemotherapy Cytotoxic drugs may be used either as adjuvant therapy or primary therapy. Decisions to start chemotherapy are based on several factors, such as the stage of the cancer and hormone receptor assay results. A typical regimen makes use of cyclophosphamide, methotrexate, doxorubicin, and fluorouracil. Hormone therapy Hormone therapy lowers the levels of estrogen and other hormones suspected of nourishing breast cancer cells. Antiestrogen therapy, with tamoxifen or raloxifene, is used in women at increased risk for developing breast cancer. Other commonly used drugs include the antiandrogen aminoglutethimide, the androgen fluoxymesterone, the estrogen diethylstilbestrol, and the progestin megestrol. Cervical cancer Cervical cancer is the third most common cancer of the female reproductive system. Preinvasive cancer ranges from minimal cervical dysplasia, in which the lower third of the epithelium contains abnormal cells, to carcinoma in situ, in which the full thickness of epithelium contains abnormally proliferating cells. Preinvasive cancer is curable in 75% to 90% of patients with early detection and proper treatment. In invasive disease, usually squamous cell carcinoma, cancer cells penetrate the basement membrane and can spread directly to contiguous pelvic structures or disseminate to distant sites by way of lymphatic routes. Invasive cancer typically occurs between ages 30 and 50; it rarely occurs younger than age 20. What to look for Preinvasive cancer produces no symptoms or other clinical changes. The patient history may suggest one or more of the predisposing factors for this disease. Looking at cervical cancer the illustrations below show cervical carcinoma in situ and squamous cell carcinoma of the cervix. Battling illness Treating cervical cancer Accurate clinical staging will determine the type of treatment. Preinvasive lesions may be treated with total excisional biopsy, cryosurgery, laser destruction, conization (followed by frequent Pap test follow-ups) or, rarely, hysterectomy. Therapy for invasive squamous cell carcinoma may include radical hysterectomy and radiation therapy (internal, external, or both). Complications Complications of surgery include: bladder dysfunction formation of lymphocytes or seromas after lymphadenectomy pulmonary embolism. Complications of radiation therapy include: diarrhea abdominal cramping dysuria leukopenia. Combined surgery and irradiation in the abdomen and pelvis may lead to small bowel obstruction, stricture and fibrosis of the intestine or rectosigmoid, and rectovaginal or vesicovaginal fistula. Overall, the lifetime risk of developing colorectal cancer is about 1 in 20, or 5%. The importance of a thorough assessment Because colorectal cancer progresses slowly and remains localized for a long time, early detection is key to recovery. Unless the tumor metastasizes, the 5-year survival rate is 80% for rectal cancer and 85% for colon cancer. The genetic angle the cause of colorectal cancer may be related to genetic factors-deletions on chromosomes 17 and 18-that may promote mutation and transition of the mucosal cells to a malignant state. This results in prolonged exposure of the bowel mucosa to digested materials and may encourage mucosal cells to mutate. Recent studies suggest that estrogen replacement therapy and nonsteroidal antiinflammatory drugs, such as aspirin, may reduce the risk of colorectal cancer. What to look for In its early stages, colorectal cancer usually causes no symptoms. Rectal bleeding, blood in the stool, a change in bowel habits, and cramping pain in the lower abdomen may signal advanced disease. Types of colorectal cancer Colorectal cancer can occur anywhere along the small and large intestine, as well as the rectum. Battling illness Treating colorectal cancer Surgery the most effective treatment for colorectal cancer is surgical removal of the malignant tumor, adjacent tissues, and cancerous lymph nodes. The illustration below shows the different locations in the colon that may be resected for tumor removal. Chemotherapy Chemotherapy or chemotherapy in combination with radiation therapy is given before or after surgery to most patients whose cancer has deeply perforated the bowel wall or has spread to the lymph nodes. Commonly used drugs include oxaliplatin in combination with fluorouracil followed by leucovorin for patients with metastatic carcinoma. Endometrial cancer Cancer of the endometrium (also known as uterine cancer) is the most common gynecologic cancer. Most premenopausal females who develop uterine cancer have a history of anovulatory menstrual cycles or other hormonal imbalance. About 33,000 new cases of uterine cancer are reported annually; of these, roughly 5,500 are fatal.
Terbinafine at a dose of 5-11 mg/kg (depending on level of involvement) was used for 1 treatment solutions buy generic citalopram 20mg on line, 2 and 4 weeks with an overall cure rate of 44% treatment spinal stenosis discount citalopram 40 mg on-line, 57% medicine norco effective citalopram 40mg, and 78% respectively (1) treatment management company cheap citalopram 40mg. In a comparison of terbinafine with griseofulvin, the primary response rates in 50 patients treated for 8 weeks were found to be 72% and 76%, respectively (4). However, at 12 weeks, fewer recurrences were seen with terbinafine with an efficacy of 76% as compared to griseofulvin with an efficacy of 64% (4). In cases of tinea capitis caused by Microsporum species, terbinafine was found to be less effective than griseofulvin with only a 32% cure rate 14 weeks after a 6-week course of therapy (4). Disadvantages of terbinafine include its decreased effectiveness against Microsporum species (compared with griseofulvin), gastrointestinal disturbances seen in 5% of patients and the potential for interactions with other drugs, such as rifampin and cimetidine (4). A 6-week course of itraconazole was found to be comparable to a 6-week course of griseofulvin (4). Itraconazole and fluconazole were found to cause minor gastrointestinal side effects in 5% of patients and cause a reversible, asymptomatic elevation in liver function tests in 1 of 17 patients (4). Predisposing factors include occlusive footwear, hot, humid weather, and walking barefoot on contaminated floors. Tinea pedis is usually seen in preadolescent and adolescent males, and less likely in younger children (3). The toe webs and soles of the feet, most commonly the lateral toe webs, are usually affected. Patients often present with severe tenderness, pruritus, foul odor, fissuring, scaling and maceration of the surrounding skin. In some cases, a diffuse hyperkeratosis of the sole of the foot with mild erythema is seen. Breaks of the skin may occur leaving a pathway for bacterial infection with group A streptococcus or Staphylococcus aureus. The infection may also spread to the inguinal area (tinea cruris), trunk (tinea corporis), hands (tinea manuum), or nails (tinea unguium). The differential diagnosis includes normal peeling of the interdigital spaces and infection by Candida or other bacterial organism. Contact dermatitis, atopic dermatitis, and dyshidrotic eczema can also mimic tinea pedis (3). The treatment of tinea pedis involves topical and systemic agents to cure and to prevent recurrence. Tolnaftate, however, can only be used in uncomplicated cases, since it is not effective against Candida species (3). In one study of 484 patients enrolled in 15 different studies, itraconazole, 200mg twice a day for one week, was found to be highly effective with a cure rate of 85% (1). Preventive measures include avoidance of occlusive footwear, use of footwear when bathing in public showers, and complete drying of the area between the toes after bathing. The use of absorbent anti-fungal powder, such as zinc undecylenate (Desenex), which does not cover Candida species, is also helpful (3). Environmental factors such as elevated temperature and increased humidity, as well as a decrease in the normal bacterial flora. Many candidal infections clear spontaneously, and are relatively minor, such as oropharyngeal candidiasis (thrush) and candidal diaper dermatitis; however, systemic candidiasis can occur, which is serious and beyond the scope of this chapter. Chronic mucocutaneous candidiasis is due to a Tcell deficiency and a specific anergy which is also beyond the scope of this chapter. Oropharyngeal candidiasis, also known as oral thrush, is rare in the first week of life. In neonates of mothers with vaginal candidiasis, oral thrush was 35 times more common than in those of non-infected mothers (6). It was found that 20% of mothers with positive vaginal cultures had neonates with positive oral cavity cultures and 11% went on to develop oropharyngeal candidiasis (6). It is important to note that approximately 31% of women with positive vaginal cultures for C. Oropharyngeal candidiasis in neonates usually develops an average of 8 days after birth (6). The incidence of oral thrush is higher in bottle-fed infants than in breast-fed infants (6). Neonates and young children are often affected because of the immaturity of host defenses and incomplete establishment of the gastrointestinal flora. Oropharyngeal candidiasis (thrush) often presents as whitish patches on the tongue, gums and buccal mucosa. The patches are adherent (but can be removed revealing a erythematous base, unlike leukoplakia which is not able to be removed) and are made of epithelial cells, leukocytes, keratin, food debris and C. The patient may exhibit decreased appetite and poor nursing due to pain and/or discomfort, but they are often asymptomatic. In untreated cases in newborns, oral thrush has been found to clear on its own in 23-59 days (6). Absorbed agents, such as fluconazole and ketoconazole, are effective, but the nonabsorbed (topical) agents are preferred because they are equally effective. Gentian violet is a non-absorbed agent composed of formaldehyde and mercurochrome. This agent is unfavorable because recurrences are common, with the additional adverse effects of ulceration and irritation of the oral mucosa, staining of tissue and clothing, and the possibility of being carcinogenic (6). Older children and teens can swish it in their mouth, but it should be applied with a cotton applicator onto the lesions in infants and young children. Miconazole is a first generation imidazole that has in vitro activity against yeast, dermatophytes and some Gram positive bacteria. Miconazole oral gel has been studied and found to be more effective than nystatin suspension. In a study of 183 ambulatory infants with no other underlying disease, 85% of infants treated with miconazole oral gel and 21% of infants treated with nystatin suspension were cured on day 5 (6). Candidal diaper dermatitis is a benign condition that often occurs concomitantly with oropharyngeal candidiasis. Infants with oropharyngeal candidiasis have been found to have candidal diaper dermatitis in about 57% of cases (6). Patients on antibiotics are at higher risk of developing candidal diaper dermatitis. Candidal diaper dermatitis often presents in the perianal area as erythematous (classically described as beefy red), confluent plaques with well defined edges and a scalloped border. There are often satellite lesions (red spots), which are the primary lesions, and are Page - 263 considered the hallmark of localized candidal infections. Candidal diaper dermatitis often extends to the perineum, upper thighs, lower abdomen and lower back. The diagnosis of candidal diaper dermatitis can be established by culture of the area. However in most instances, the diagnosis is made clinically by its characteristic appearance. Treatment of candidal diaper dermatitis involves topical therapy such as nystatin, miconazole or clotrimazole. In patients that have frequent recurrences of candidal diaper dermatitis, oral therapy may be used. The mycologic cure rates were the same, but oral nystatin reduced the recurrence rate to 16%, compared to 33% for topical nystatin alone (6). The dimorphic yeast, Malassezia furfur (previously known as Pityrosporum ovale and Pityrosporum orbiculare), is the infecting organism. This organism is more commonly seen in areas of the skin with sebum production capabilities and infection is seen more commonly in adolescents and young adults (3). In lighter skinned individuals, the lesions are typically seen as reddish-brown macules with fine scales. In darker skinned individuals, the lesions may appear as hyperpigmented or hypopigmented macules. The lesions usually start in a perifollicular area then coalesce to form the macular, scaly lesions. Involved areas are usually not pruritic and they do not darken after sun exposure. Skin biopsy with culture and periodic acid-Schiff staining for fungi may be necessary to diagnose cases with principally follicular involvement.
