Scaphoid fracture is a common injury encountered in family medicine. To avoid missing this diagnosis, a high index of suspicion and a thorough history and physical examination are necessary, because early imaging often is unrevealing. Anatomic snuffbox tenderness is a highly sensitive test for scaphoid fracture, whereas scaphoid compression pain and tenderness of the scaphoid tubercle tend to be more specific. ⋯ Nondisplaced distal fractures generally heal well with a well-molded short arm cast. Although inclusion of the thumb is the standard of care, it may not be necessary. Nondisplaced proximal, medial, and displaced fractures warrant referral to an orthopedic subspecialist.

Because advance directives are not yet the norm, end-of-life decisions for patients without medical decision-making capacity are made regularly within discussions between the patient's physician and family. Communication and decision making in these situations require a complex integration of relevant conceptual knowledge of ethical implications, the principle of surrogate decision making, and legal considerations; and communication skills that address the highly charged emotional issues under discussion. The most common pitfalls in establishing plans of care for patients who lack decision-making capacity include failure to reach a shared appreciation of the patient's condition and prognosis; failure to apply the principle of substituted judgment; offering the choice between care and no care, rather than offering the choice between prolonging life and quality of life; too literal an interpretation of an isolated, out-of-context, patient statement made earlier in life; and failure to address the full range of end-of-life decisions from do-not-resuscitate orders to exclusive palliative care.

After infancy, galactorrhea usually is medication-induced. The most common pathologic cause of galactorrhea is a pituitary tumor. Other causes include hypothalamic and pituitary stalk lesions, neurogenic stimulation, thyroid disorders, and chronic renal failure. ⋯ Bromocriptine is the preferred agent for treatment of hyperprolactin-induced anovulatory infertility. Although cabergoline is more effective and better tolerated than bromocriptine, it is more expensive, and treatment must be discontinued one month before conception is attempted. Surgical resection rarely is required for prolactinomas.

Insulin therapy for type 2 diabetes: rescue, augmentation, and replacement of beta-cell function.
Type 2 diabetes is characterized by progressive beta-cell failure. Indications for exogenous insulin therapy in patients with this condition include acute illness or surgery, pregnancy, glucose toxicity, contraindications to or failure to achieve goals with oral antidiabetic medications, and a need for flexible therapy. Augmentation therapy with basal insulin is useful if some beta-cell function remains. ⋯ Adjustments should be made systematically, starting with the fasting, then the preprandial and, finally, the postprandial glucose levels. Basal therapy with glargine insulin provides similar to lower A1C levels with less hypoglycemia than NPH insulin. Insulin aspart and insulin lispro provide similar A1C levels and quality of life, but lower postprandial glucose levels than regular insulin.
