Natal teeth: a review.
The incidence of natal teeth is approximately 1:2,000 to 1:3,000 live births. The most commonly affected teeth are the lower primary central incisors. Natal teeth usually occur in pairs. The eruption of more than two natal teeth is rare. The majority of natal teeth represent the early eruption of normal primary deciduous dentition. Less than 10% of natal teeth are supernumerary. Natal teeth might resemble normal primary dentition in size and shape; however, the teeth are often smaller, conical and yellowish, and have hypoplastic enamel and dentin with poor or absent root formation. Complications include discomfort during suckling, sublingual ulceration, laceration of the mother's breasts and aspiration of the teeth. A dental roentgenogram is indicated to differentiate the premature eruption of a primary tooth from a supernumerary tooth. Tooth extraction is indicated if the tooth is supernumerary or excessively mobile. If the tooth does not interfere with breastfeeding and is otherwise asymptomatic, no treatment is necessary.

Recurrent panniculitis in an adolescent boy with Prader-Willi syndrome.
We describe recurrent panniculitis in a 15-year-old boy with Prader-Willi syndrome. To our knowledge, this association has not been previously reported.

Penile and oral angioedema associated with peanut ingestion.
Angioedema is characterized by transient, episodic, nonpruritic, nonpitting and well-defined edema that involves the subcutaneous or submucosal tissue, and most commonly develops in the head and neck region. Angioedema is caused by extravasation of plasma into the interstitial space of the affected tissue. We describe a six-year-old boy who developed oral and penile angioedema subsequent to the ingestion of peanuts.

Urinary tract infection due to Salmonella stanleyville in an otherwise healthy child.
A healthy four-year-old boy developed a febrile urinary tract infection (UTI) due to Salmonella stanleyville. The UTI developed following an episode of enteritis due to the same organism. Salmonella UTI is uncommon and is reported more often in patients with a predisposing factor, such as immune deficiency or a structural abnormality, in the urinary tract. Salmonella stanleyville has not been previously reported as a cause of UTI.

Successful alpha-1 receptor blockade therapy in a toddler with infrequent and difficult voiding.
A 3-year-old neurologically intact and behaviorally normal boy developed infrequent and difficult voiding subsequent to a soft tissue injury to the glans penis. Symptoms persisted for at least 9 months, and the course was complicated by diagnostic imaging evidence of a "markedly distended" bladder and a voiding diary that suggested elevated bladder volumes. Treatment with an alpha-1 receptor blocker normalized voiding within 24 hours. Discontinuation of the medication after 2 weeks resulted in recurrence of symptoms within 48 hours. Readministration of the medication resulted in prompt resolution of symptoms.

Traveler's diarrhea.
Travelers' diarrhea is common. Between 8% and 50% of travelers develop diarrhea; incidence depends on the country visited. The attack rate is highest for travelers from a developed country who visit a developing country. Children are at particular risk. Travelers' diarrhea is usually acquired through ingestion of fecally contaminated food and water. Most cases are due to a bacterial pathogen, commonly, Escherichia coli, and occur within the first few days after arrival in a foreign country. More than 90% of episodes develop within the first 2 wk of initiation of travel. Dehydration is the most common complication. Water and electrolyte replenishment is important and can usually be accomplished with an oral rehydration solution. Judicious use of an antimotility agent and antimicrobial therapy reduces the duration and severity of diarrhea. Pretravel education on hygiene and on the safe selection of food items is important in minimizing episodes. Dukoraltrade mark (Aventis Pharma Ltd., Auckland, New Zealand) vaccine should be considered for travelers who are 2 y of age or older and who will be visiting an area associated with risk of infection due to enterotoxigenic E coli or Vibrio cholerae. Typhoid vaccine is recommended for travelers who will be visiting areas with poor sanitation and hygiene.

Penile dog bite in an adolescent.
Dog bites to the external genitalia are rare. In this case, a 16-year-old boy suffered a dog bite wound to the penis. The wound was cleansed with copious amounts of sterile normal saline by means of high-pressure syringe irrigation. The child had an uneventful recovery.
