There have been reports of depres- 2 DERMATOLOGY 31 sion and suicide in isotretinoin-treated patients buy discount nolvadex 20 mg line women's health clinic riverside campus. This association remains controversial purchase 20 mg nolvadex women's health issues 2012, but this risk must be discussed with the patient before starting therapy. A 16-year-old female patient comes to your office complaining of pimples. She states that the pimples appeared on her face 2 to 3 months ago. She has also noticed some deepening of her voice and the appearance of an increasing amount of hair on her chin and breasts. Her menses were regular until 4 or 5 months ago, when she started noticing irregular and short-lasting periods. On physical examination, the patient has papules and pustules on her face. Hirsutism is noted on her face, arms, breasts, and infraumbilical area, and she has an enlarged clitoris. Which of the following is the most appropriate step to take next in the treatment of this patient? Evaluate the patient for the possibility of ovarian or adrenal tumors B. Start oral contraceptives for presumed polycystic ovarian syndrome (PCOS) and provide reassurance C. Start low-dose hydrocortisone for presumed late-onset congenital adre- nal hyperplasia and follow up in 2 months D. Start benzoyl peroxide with topical metronidazole in the morning and topical retinoids at night E. Administer a pregnancy test and consider isotretinoin therapy Key Concept/Objective: To know the secondary causes of acne Acne is very common in the adolescent population; however, it is important to recognize acne as a secondary manifestation of a primary process. Acne can be caused by medica- tions such as isoniazid, corticosteroids, phenytoin, lithium, and progestins. Acne can also be a manifestation of androgen excess; this patient had acne of rapid onset, and there were other manifestations of androgen excess, such as changes in her voice, oligomenorrhea, clitoromegaly, and hirsutism. This rapid onset is characteristic of tumors producing andro- gens, which are frequently located in the ovarian or adrenal glands. Levels of testosterone, free testosterone, and dehydroepiandrosterone sulfate should be measured; if the results are high, imaging studies are indicated. PCOS can cause oligomenorrhea, hirsutism, and acne; however, it should not cause clitoromegaly or voice changes. Late-onset congenital adrenal hyperplasia (CAH)—21-hydroxylase deficiency in particular—is in the differential diagnosis. However, it would be atypical for it to present in such a rapid manner. If the workup for the presence of a tumor is negative, further workup for CAH would be indi- cated. A 38-year-old man presents to your clinic complaining of hair loss. He reports that the hair loss began several years ago but is more noticeable now. His hair has been thinning out on the sides as well as on the top of his head. He reports that several family members have the same problem. Which of the following is the most appropriate therapy for this patient’s condition? Topical 2% minoxidil applied to the scalp twice daily B. Medium- to high-potency topical steroids applied daily C. Topical immunotherapy with the sensitizing chemical diphencyprone D.

The patient has optic neuritis buy nolvadex 10mg menstrual urination; she is at no risk of progressing to MS in the future D trusted nolvadex 10 mg menstruation calculator. The patient has MS; she should be started on mitoxantrone Key Concept/Objective: To know the association between optic neuritis and MS Optic neuritis is an acute inflammatory optic neuropathy. The cardinal symptoms are uni- lateral vision loss and retrobulbar pain with eye movement. Treatment with intravenous methylprednisolone followed by oral prednisone hastens recovery of vision. Even without treatment, almost all patients begin to recover vision within 4 weeks. The relationship of optic neuritis to MS is controversial. Some regard optic neuritis as a distinct entity, but oth- ers consider it part of the clinical continuum of MS. More than half of all patients with MS have optic neuritis at some time during the course of disease. Of patients who present with optic neuritis and who have no other neurologic deficit, almost 40% have one or more ovoid periventricular lesions on brain MRI; clinically definite MS eventually develops in 60%. Patients with completely normal results on MRI and comprehensive CSF evaluation seldom progress to MS. A 44-year-old man comes to the hospital complaining of progressive lower extremity weakness and decreased sensation. He also complains of having difficulties with bowel movements and urination. He recalls having an upper respiratory infection 1 or 2 weeks ago. His physical examination is remarkable for decreased sensation starting at the level of T10, symmetrical severe lower extremity weakness, urinary retention, and decreased rectal tone. The muscle tone and deep tendon reflexes in his lower extremities are diminished. T2-weighted MRI of the spinal cord shows a hyperintense lesion that involves the majority of the cross-sectional area of the cord; the lesion extends from T6 to L3. Of the following, which is the most likely diagnosis? MS Key Concept/Objective: To be able to recognize transverse myelitis Acute transverse myelitis is a syndrome of spinal cord dysfunction. It has a rapid onset; it may occur after infection or vaccination or it may occur with no discernible precipitant. Symptoms include paraparesis, which is ini- tially flaccid and then spastic; loss of sensation with a sensory level in the trunk; and bowel and bladder dysfunction. MRI is extreme- ly helpful for excluding other structural lesions and for confirming the presence of an intramedullary lesion, which is typically hyperintense in T2-weighted imaging. No treat- ment has proven to be beneficial, but corticosteroids are often used. Neuromyelitis optica is also known as Devic disease. It is characterized by the simultaneous or sequential involvement of the optic nerves and spinal cord; it often has a malignant course. Acute dis- seminated encephalomyelitis is a monophasic syndrome that is usually preceded by a viral exanthema, an upper respiratory infection, or vaccination. Onset is rapid and is charac- terized by meningeal signs, headache, seizures, and altered mental status. The neurologic deficits include hemiplegia, paraplegia, sensory loss, vision loss, and transverse myelitis. In this patient, the lack of multiple lesions and the monophasic nature of the disease make the diagnosis of MS less likely. A 43-year-old woman with a 14-year history of MS with lower-extremity spasticity presents with increased spasticity, mild confusion, abdominal discomfort, and a temperature of 100° F (37. Which of the following choices best combines medical indication and favorable cost-benefit ratio?
