Unusual diffuse pulmonary lymphatic proliferation in a young boy.

We describe a 4-year-old boy who died of an unusual generalized pulmonary lymphatic proliferation. His condition cannot clearly be categorized with any of the previously described pulmonary lymphatic disorders.

Exercise-induced "asthma" as a presentation of bronchial carcinoid.

Exercise-induced wheezing developed in a previously healthy 14-year-old boy. Chest radiographs revealed hyperlucency of the left lung. Bronchial tomography and bronchoscopy revealed a mass in the left mainstem bronchus, identified as a carcinoid tumor after surgical excision. The patient is now asymptomatic. Exercise-induced wheezing as the sole manifestation of this tumor has not been previously reported.

Eosinophilic gastroenteritis: a case report and review of the literature.

A 13-year-old boy was hospitalized with gastrointestinal obstruction. During evaluation, the total eosinophil count was as high as 3,332/mm. A biopsy specimen of the small bowel obtained at laparotomy revealed an intense eosinophilic infiltrate of the muscularis. Symptoms were controlled with glucocorticoid therapy. The case is unusual in that the eosinophilic gastroenteritis presented as childhood gastrointestinal obstructive disease with involvement of the colon but sparing of the stomach.

Peanut oil is not allergenic to peanut-sensitive individuals.

Ten peanut-sensitive patients were enrolled in a double-blind crossover trial to determine whether ingestion of peanut oil can induce adverse reactions in such individuals. All patients had experienced prior allergic reactions to peanut ingestion, including any of the following: generalized urticaria, angioedema, abdominal cramps, vomiting, diarrhea, bronchospasm, or shock. All patients had elevated levels of serum IgE antibodies to both crude peanut extract and the purified peanut allergen, Peanut-I, by RAST assay; binding values ranged from 2 to 26 times that of negative control serum. All patients demonstrated negative puncture skin tests to both peanut oil and olive oil (control). At 30-min intervals, patients ingested 1, 2, and 5 ml of either oil contained in 1 ml capsules while under constant observation. These quantities exceed the maximum estimated dose of peanut oil that would occur in single meals. Patients returned 2 wk later for ingestion challenge with the remaining oil. No untoward reactions were observed with either peanut oil or olive oil. Peanut oil ingestion does not pose a risk to peanut-sensitive individuals.
