The "A" in the title stands for acrodermatitis enteropathica, an uncommon underlying cause of diaper dermatitis (DD). The "Pee," the colloquial term for urine, is probably the most common irritant (along with feces) that contributes to the breakdown of skin in the diaper area.

Primary care and emergency physicians frequently see young children who have fractured a bone after a fall from a low height. The child's caregiver may describe a fall from furniture, play equipment, stairs, and various other structures--or the child may have even been dropped while being carried. The clinician then has to decide whether the explanation for the fall is plausible--or whether a child abuse investigation should be pursued.

The mother of this 2-month-old boy was concerned about her son's facial asymmetry that was apparent only when he was crying. The right angle of the infant's mouth dropped substantially below the left angle of the mouth when he cried; it also deviated to the right (A). The moment the child stopped crying, his mouth became symmetric again (B).

This day-old, macular, blanching, nonpruritic rash had developed in the right axilla and on the right arm and right side of the trunk of a 3 1/2-year-old boy. He was otherwise asymptomatic. Other physical examination findings were unremarkable.

A 9-year-old Hispanic boy presented with submental swelling and dysphagia. The swelling had progressed over 5 days. He had no history of fever, difficulty in breathing, or voice change.

Case In Point: Infantile Hypertrophic Pyloric Stenosis
BySamir Joshi, MD,Linda S. Nield, MD,Deepak M. Kamat, MD, PhD,Prashant Mahajan, MD, MPH, MBA,Deepak M. Kamat, MD, PhD A 7-week-old white boy presented to the emergency department (ED) with vomiting and weight loss. His parents brought him to the ED 3 weeks earlier after he had vomited for several days. Possible milk protein allergy was diagnosed at that visit, and a change from cow milk formula to an elemental formula was recommended. Vomiting subsequently increased in frequency. Nonbilious but forceful vomiting occurred with each feeding. The patient lost nearly 2 lb during the 3 weeks that followed the first ED visit.

An otherwise healthy 11-month-old infant hadhad an intermittent, nonpruritic rash for mostof his life. The lesions recurred mainly onthe extremities and trunk without a particulartrigger. Applications of 1% hydrocortisonecream were only partially beneficial. The joints and nailswere not affected. The patient’s maternal grandfather hadsevere psoriasis.

Pediatricians around the countryare being bombardedwith questions about avianflu. This brief review of thecurrent status of the avian fluoutbreak and its treatment and preventionprovides the informationyou will need to answer the mostpressing patient questions.

"Flu" Season: Here We Go Again . . .

A 4-day-old boy was transferred to our institution for evaluation of multiple anomalies. He was born to a gravida 2 para 1 mother at 38 weeks of gestation. He weighed 3288 g at birth. Antenatal ultrasonograms at 5, 6, and 7 months had revealed short bones in the legs. The mother was subsequently lost to follow-up--until now.

Pneumonia is one of the most common conditions encountered by primary care providers. Certain organisms cause pneumonia in particular age groups. For example, group B streptococci, Gram-negative bacilli Escherichia coli in particular) and, rarely, Listeria monocytogenes cause pneumonia in neonates. In infants younger than 3 months, group B streptococci and organisms encountered by older children occasionally cause pneumonia, as does Chlamydia trachomatis. Older infants and preschoolers are at risk for infection with Streptococcus pneumoniae and Haemophilus influenzae. In children older than 5 years, S pneumoniae and Mycoplasma pneumoniae are the key pathogens. Let the patient's age, history, clinical presentation, and radiographic findings guide your choice of therapy. Even though most patients with uncomplicated pneumonia can be treated as outpatients, close follow-up is important. Hospitalize patients younger than 6 months and those with complications.

ABSTRACT: Children are at greater risk than adults for many travel-related problems, such as barotitis and barotrauma associated with flying, cold and heat injury, drowning, and infection with geohelminths. Most of these problems can be avoided with appropriate measures. To prevent insect-borne diseases, advise parents to apply permethrin to their children's clothing before the trip and apply slow-release DEET (30% to 35% concentration) to their skin every 24 hours. Infection with ground-dwelling parasites can be avoided by wearing protective footwear. At high altitudes, infants and children may experience acute mountain sickness. Acetozolamide (5 mg/kg/d, divided bid or tid) is an effective prophylactic; however, it is contraindicated in patients with sulfa allergy. Some preventive measures that are effective in adults may not be appropriate for children; for example, several medications used to control motion sickness are ineffective and associated with significant side effects in children.

Genetic Disorders: Newborn With Multiple Anomalies

ABSTRACT: Asthma is a very serious yet very controllable illness. In acute exacerbations, bronchospasm can be reversed with nebulized albuterol (2.5 to 5 mg); give 2 additional treatments at 20-minute intervals and then every hour for the first few hours until wheezing resolves. Subcutaneous terbutaline and epinephrine are alternatives. Systemic corticosteroids may be needed to manage the acute attack (eg, 2 mg/kg of oral prednisone or pred-nisolone). In addition, an anticholinergic agent (eg, inhaled ipratropium) may be used. IV magnesium (25 to 50 mg/kg) and heliox have shown promising results in acute asthma. Maintenance therapy is indicated when daily symptoms occur more than twice per week or when nighttime symptoms occur more than twice per month; such therapy may also be warranted for an infant with exacerbations that occur less than 6 weeks apart or more than 3 times per year, or when other risk factors are present. Inhaled corticosteroids are the cornerstone of maintenance therapy and are mandatory for all patients with persistent asthma. Alternative treatments for children younger than 5 years include cromolyn and an oral leukotriene modifier (montelukast). Patient and parent education helps ensure proper drug administration, monitoring, and compliance.

A 12-year-old boy was brought by ambulance to the emergency department (ED) with fever and shaking of 3 days' duration. He was accompanied by his mother. The boy had spent the weekend at his father's home when he began to feel sick. Since returning to his mother's house, he has been lethargic and has had one episode of vomiting.
