Police brought a delirious, combative 24-year-old man to the emergency department. The patient was unable to provide any history on arrival, but his scarred, blistering lips and his vital signs (blood pressure, 166/102 mm Hg; heart rate, 97 beats per minute; respiratory rate, 24 breaths per minute; and temperature, 38.2°C, or 100.9°F) led to a possible diagnosis of cocaine-induced delirium.

A 52-year-old man from Bangladesh had suffered from pleuritic pain for 1 week. He had never had tuberculosis and-except for being a cigarette smoker-had no notable medical history. The only remarkable findings were a temperature of 37.5°C (99.5°F) and anterior tenderness over the right lower rib cage. Laboratory test results were normal.

He had no respiratory symptoms.
A 45-year-old man with a history of congestive heart failure presented with cough and dyspnea. A chest roentgenogram showed loculated pleural effusion in the horizontal fissure of the right lung, and a CT scan revealed pleural-based density in that lung.
A 19-year-old man was admitted to the hospital with malaise, fatigue, and intermittent fever (temperature of 38°C [100.4°F]) for the last 2 weeks. Physical examination revealed scarce purpuric lesions over the lower extremities; a pericardial friction rub was audible over the precordium when the patient was supine and seated, and the spleen was remarkably enlarged.

An obese 56-year-old woman was hospitalized after 2 days of chest pain, shortness of breath, and palpitations. Physical examination revealed no abnormalities, and serial cardiac enzyme studies and an ECG ruled out myocardial infarction. However, transesophageal echocardiography showed a lesion in the mediastinum.
The parents of a 2-year-old boy with a 3-day history of fever took him to the emergency department. The child's temperature fluctuated between 38°C (100.4°F) and 39°C (102.2°F). As part of the workup, chest films were taken.

This 63-year-old woman's primary care physician had referred her to an ophthamologist because of her persistently red eye. She had been treated unsuccessfully for almost 3 weeks with several different antibiotic eyedrops. Her vision had begun to worsen, and she started to hear “swishing” noises.
