Causes and evaluation of mildly elevated liver transaminase levels.
Mild elevations in levels of the liver enzymes alanine transaminase and aspartate transaminase are commonly discovered in asymptomatic patients in primary care. Evidence to guide the diagnostic workup is limited. If the history and physical examination do not suggest a cause, a stepwise evaluation should be initiated based on the prevalence of diseases that cause mild elevations in transaminase levels. ⋯ If test results are normal, a trial of lifestyle modification with observation or further testing for less common causes is appropriate. Additional testing may include ultrasonography; measurement of α(1)-antitrypsin and ceruloplasmin; serum protein electrophoresis; and antinuclear antibody, smooth muscle antibody, and liver/kidney microsomal antibody type 1 testing. Referral for further evaluation and possible liver biopsy is recommended if transaminase levels remain elevated for six months or more.

Heel pain is a common presenting symptom in ambulatory clinics. There are many causes, but a mechanical etiology is most common. Location of pain can be a guide to the proper diagnosis. ⋯ Sinus tarsi syndrome occurs in the space between the calcaneus, talus, and talocalcaneonavicular and subtalar joints. The syndrome manifests as lateral midfoot heel pain. Differentiating among causes of heel pain can be accomplished through a patient history and physical examination, with appropriate imaging studies, if indicated.

ReviewPremenstrual syndrome and premenstrual dysphoric disorder.
Premenstrual syndrome is defined as recurrent moderate psychological and physical symptoms that occur during the luteal phase of menses and resolve with menstruation. It affects 20 to 32 percent of premenopausal women. Women with premenstrual dysphoric disorder experience affective or somatic symptoms that cause severe dysfunction in social or occupational realms. ⋯ Symptom relief is the goal for treatment of premenstrual syndrome and premenstrual dysphoric disorder. There is limited evidence to support the use of calcium, vitamin D, and vitamin B6 supplementation, and insufficient evidence to support cognitive behavior therapy. Serotonergic antidepressants (citalopram, escitalopram, fluoxetine, sertraline, venlafaxine) are first-line pharmacologic therapy.
