A 49-year-old woman was admitted tothe hospital with a high fever ofabrupt onset, rigor, headache, myalgias,and profound prostration. Hertemperature was 41ºC (105.8ºF);blood pressure, 60/40 mm Hg; respirationrate, 30 breaths per minute;and pulse rate, 130 beats per minute.

A 55-year-old woman had a 10-day historyof a nonproductive cough and apainful rash on both palms for 5 days.The eruption subsequently spreadover her entire body.

A pruritic, erythematous rash developed in a 6-year-oldboy over 5 days. The rash erupted in crops; the lesions appearedinitially as rose-colored macules, progressed rapidlyto papules and vesicles, and finally crusted (A). The distributionof the lesions-with the greatest concentrationon the trunk-is typical of chickenpox.

A generalized pruritic, vesicular eruption on an erythematousbase developed in a 34-year-old man. His palms andsoles were not involved

A 30-year-old man presented with a few-day history of aviral prodrome, including a low-grade fever, mild headache,muscle and joint aches, and malaise, accompaniedby a vesiculopapular rash. The mildly pruritic eruptionbegan on the head and neck and progressed within 36hours to the trunk and proximal extremities; the palmsand soles were spared.

A 67-year-old woman was admitted to the hospital with fever, chills, unilateral flank pain, dysuria, and urinary frequency and urgency. Her past medical history included several febrile relapses of infection.

Occasionally, protective splinting with plaster of Paris splints can create problems, particularly in patients with diabetes and loss of protective sensation who are readily susceptible to pressure sores.

Infection of the “simple” open fractureof the distal radius is a significant-but fortunately rare-complication ofimmobilizing musculoskeletal injuriesof the upper extremity. Cliniciansoften underestimate the extent towhich this type of fracture can be contaminated,particularly if the patientpresents with a small puncture wounddirectly over the fractured distal radiusthat conceals the degree of contaminationat the fracture site. If openfractures of the distal radius are simplywashed out in the emergency department and temporarily splinted, overwhelming sepsis fromclostridial myonecrosis may develop, leading to amputation.

24-year-old woman had experienced perianal itching and a small amount of rectal bleeding for 6 months. She also complained of a perianal protrusion.

One week after redness and swelling arose on the left second finger, a 33-year-old man sought medical evaluation. He reported some tenderness and difficulty in flexing the digit but could not recall injuring the finger. The medical history included treatment of seborrheic dermatitis and acne.

Seen here are asymptomatic papillary growths on the gingiva of a 31-year-old homosexual man who is seropositive for HIV. The diagnosis of human papillomavirus (HPV) lesions can be based on appearance and history. Condylomas may also appear flat and smooth or nodular, resembling fibromas. Because cross infection is common, patients who have these lesions-and their partners-are at increased risk for contracting anal and genital condylomas.

A 28-year-old white man presented with a recent-onset rash that involved the upper arms.
