Photoclinic: Cutaneous Calcinosis in a Child With Tertiary Hyperparathyroidism

The rate of melanoma among children and young adults rose dramatically between 1973 and 2001, according to a study in a recent issue of the Journal of Clinical Oncology. "Between the years 1973 and 2001, the incidence of pediatric melanoma increased 2.9% per year and 46% per year of age," says John Strouse, MD, a pediatric oncologist and instructor in pediatrics at the Johns Hopkins University and author of the article.

Allergic diseases are the sixth leading cause of chronic disease in the United States and cost the health-care system more than $18 billion a year. But despite the seriousness suggested by these numbers, many people don't understand how deflating allergies can be to quality of life for patients and families, according to Mark Boguniewicz, MD, professor at Denver's National Jewish Medical and Research Center.

ABSTRACT: Hypothermia is not limited to the northern states: people also die of hypothermia in other areas with milder climates. Infants, young adolescent boys, and inadequately dressed teens who abuse alcohol or illicit drugs are at highest risk for death secondary to hypothermia. The mildly hypothermic patient may appear fatigued and display persistent shivering, ataxia, clumsiness, confusion, tachypnea, and tachycardia. The child with moderate hypothermia will not be shivering; declining mental status may cause the freezing patient to remove clothing. An irregular heartbeat is likely at this stage. Severe hypothermia is marked by apnea, stupor, and coma. In a frostbitten patient, rapid rewarming of the affected area in warm water for 15 to 30 minutes is the first step. Potent analgesia is often necessary. After thawing, the frostbitten part is kept dry, warm, and loosely covered. With an adequate dose of common sense, the vast majority of deaths from cold injury can be prevented.

A 2-year-old boy was brought for evaluation of a rash and fever of 2 days' duration. He had atopic dermatitis since 6 months of age that was partially controlled with low-potency topical corticosteroids and emollients.

His mother had a history of "cold sores."

A 3-year-old boy presented with a pruritic perianal rash, rectal pain, and constipation of 3 weeks' duration. The child had initially been treated for pinworms by one of his caregivers.

In the aftermath of Hurricane Katrina's devastation in the Gulf Coast region, it is important for physicians in the United States to consider the infectious disease risks for children who have been displaced or who are still living in affected areas. These risks include infections acquired through ingestion of waterborne organisms; wound infections; lack of immunization continuity; and overcrowding, which increases the risk of respiratory or GI infections. In addition, problems will arise from disruption of therapy for select populations of children, such as those who are HIV-infected; those receiving immunosuppressive treatment; and those in need of continuous antibiotic prophylaxis, such as those who have sickle cell disease.

This black lesion had been present on the upper back of a 5-year-old girl since her birth. The lesion had gradually enlarged to its current size of 1.5 cm. In the past year, 3 satellite black macules had developed in the surrounding area.
