Recurrent acute interstitial nephritis induced by azithromycin.
A 14-year-old girl is reported with recurrent, azithromycin-induced, acute interstitial nephritis. The second episode was more severe than the first; and although both were treated with intensive corticosteroid therapy, renal function remained impaired. Although most cases of antibiotic induced acute interstitial nephritis are benign and self-limited, some patients are at risk for permanent renal injury.
Infantile Henoch-Schönlein purpura.
We present an infant with generalized palpable purpura, arthritis and fever, whose findings were atypical for classic childhood Henoch-Schönlein purpura (HSP). By describing the clinical symptoms and prognostic differences seen in infants versus school age children, we encourage physicians to be aware of infantile HSP in their differential diagnosis when they encounter a non-toxic infant with generalized purpura.

Seizure disorder as a risk factor for gastroesophageal reflux in children with neurodevelopmental disabilities.
The proportion of children with severe neurodevelopmental disabilities, in whom symptoms of gastroesophageal reflux develop after gastrostomy placement, has not been well studied. The medical records of children who received a gastrostomy tube (with or without a simultaneous antireflux procedure) at our institution between 1987 and 1997 were reviewed to identify neurologically related diagnoses at the time of the gastrostomy, diagnostic tests ordered to detect reflux, and dates and reasons for re-admissions within 2 years of discharge. Of 102 patients studied, 37 received a gastrostomy tube alone. Complete follow-up data were available for 30 of these patients, 7 of whom (23%) required subsequent antireflux surgery within 2 years. Patients with a seizure disorder had greater than a 4-fold risk of re-admission for this operation compared with other patients (57% [4/7] vs. 13% [3/23]; P=0.03). In a child with severe neurodevelopmental disability, the existence of a seizure disorder at the time of a gastrostomy operation increases the risk of subsequently requiring an antireflux procedure by a factor of 4.
