Primary care physicians must be able to recognize wrist and hand injuries that require immediate attention. A complete history and physical examination, including assessment of distal limb function, are essential. Hemorrhage control is necessary in patients with vessel lacerations and amputations. ⋯ High-pressure injection injuries and compartment syndromes require a high index of suspicion for early recognition. Infectious entities include "fight bite," open fractures, purulent tenosynovitis, animal bites, and retained foreign bodies. Tendon disruptions should be recognized early to optimize management.

Impaired glucose tolerance and impaired fasting glucose form an intermediate stage in the natural history of diabetes mellitus. From 10 to 15 percent of adults in the United States have one of these conditions. Impaired glucose tolerance is defined as two-hour glucose levels of 140 to 199 mg per dL (7.8 to 11.0 mmol) on the 75-g oral glucose tolerance test, and impaired fasting glucose is defined as glucose levels of 100 to 125 mg per dL (5.6 to 6.9 mmol per L) in fasting patients. ⋯ When the diagnosis of impaired glucose tolerance or impaired fasting glucose is made, physicians should counsel patients to lose 5 to 7 percent of their body weight and engage in moderate physical activity for at least 150 minutes per week. Drug therapy with metformin or acarbose has been shown to delay or prevent the onset of diabetes. However, medications are not as effective as lifestyle changes, and it is not known if treatment with these drugs is cost effective in the management of impaired glucose tolerance.

Lyme disease is the most common vector-borne illness in the United States. It is caused by the spirochete Borrelia burgdorferi, which is transmitted by the deer tick. Deer ticks have a four-stage life cycle (egg, larva, nymph, and adult), and nymphal ticks transmit B. burgdorferi to humans more frequently than adult ticks. ⋯ If erythema migrans develops at the site of the bite, treatment may include doxycycline in persons who are at least eight years of age. Administration of amoxicillin is appropriate for pregnant women or children younger than eight years. For those who are allergic to these medications, cefuroxime axetil may be used.
