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.
