The diagnosis of depression in older patients is often complicated by comorbid conditions, such as cerebrovascular disease or dementia. Tools specific for this age group, such as the Geriatric Depression Scale or the Cornell Scale for Depression in Dementia, may assist in making the diagnosis. Treatment decisions should consider risks associated with medications, such as serotonin syndrome, hyponatremia, falls, fractures, and gastrointestinal bleeding. ⋯ Depression is common after stroke or myocardial infarction, and response to antidepressant treatment has been linked to vascular outcomes. Depression care management is an important adjunct to the use of antidepressant medications. Structured psychotherapy and exercise programs are useful treatments for select patients.

Shave and punch biopsies are essential procedures for physicians who manage skin conditions. These office-based procedures can diagnose questionable dermatologic lesions, including possible malignancies. Approaches include the superficial shave biopsy, saucerization excision, punch biopsy, and elliptical excision. ⋯ Punch biopsies yield full-thickness samples and can be used for lesions that require dermal or subcutaneous tissue for diagnosis. Indications for biopsy of suspected melanoma remain controversial. Sufficient tissue may be obtained with the quicker, less costly saucerization biopsy or the more time-consuming, invasive elliptical excisional biopsy.

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.
