Obesity Medicine

ABSTRACT: Heel pain that occurs with the first several steps in the morning and diminishes as walking continues is the classic symptom of plantar fasciitis. Assessment of risk factors, such as improper footwear, a change in physical activities, and a new running surface, is important. Radiographs are rarely useful. Plantar fasciitis is generally self-limited; symptoms typically take 6 to 18 months to resolve. Conservative measures may include relative rest, stretching, strengthening, shoe modifications, orthoses, night splints, NSAIDs, and ice therapy. A corticosteroid injection may be warranted in resistant cases. If extensive conservative treatment is unsuccessful, referral to an orthopedic surgeon may be indicated.

A 48-year-old woman is evaluated for transfer to the ICU. She presented to the emergency department 48 hours ago with severe abdominal pain and emesis. The pain had started several days earlier and was located in the upper abdomen with some radiation to the back. No position--even the fetal position--provided relief. After admission, she was given intravenous fluids and analgesics; in the last several hours, her condition has deteriorated. She now complains of thirst and is somewhat agitated.

For a week, a 39-year-old woman with a history of intravenous heroin use had generalized pain, fever, chills, and a nonproductive cough. She rated the pain at 10 on a scale of 1 to 10; it was sharp, constant, and unrelieved by heroin. She also reported dyspnea at rest, pleuritic chest pain, and a 15-lb weight loss over the past month. She had no significant medical history or drug allergies, smoked a half pack of cigarettes per day, and denied alcohol use.

For several days, the left eye and eyelids of a 60-year-old obese man had been red and irritated. The symptoms were worse in the morning after waking. The patient had recently started wearing a nighttime continuous positive airway pressure mask for obstructive sleep apnea (OSA). He slept exclusively on his left side.
