A review of the charts of 79 patients with urticaria was conducted in a residency-based family practice center. All patients seen with urticaria in 7 years who were identified by the practice-data retrieval system were included in the review. The annual incidence of urticaria was 0.27 percent. ⋯ In 25 charts coded for other skin disorders, three cases (12 percent) of urticaria were noted by the chart reviewers. Coding errors involving digit transposition were noted in three of 1,044 cases. Diagnostic error, incorrect coding by nonphysicians or by physicians not familiar with the coding system, or even clerical error may be a significant problem in this type of study.

Comparative Study
New screening method for occult gastrointestinal bleeding: immunologic and guaiac slide tests.
A valid mass screening method for occult, bleeding gastrointestinal pathology including colorectal cancer should be monospecific for human hemoglobin, sensitive for approximately 3 mg of human blood per 1 g of stool, capable of differentiating upper and lower gastrointestinal bleeding, cost effective, uncomplicated, and acceptable to patients. Hemoccult II, a guaiac peroxidase detection test, is nonspecific for human blood and cannot differentiate between upper and lower gastrointestinal bleeding. ⋯ The findings of this study indicate that the immunologic test may remedy the deficiencies of the guaiac test. The concomitant use of the immunologic and appropriately sensitive guaiac test appears to fulfill screening test requisites.

The acute onset of stridor in a young child usually represents viral croup, particularly during the fall and early winter. If the clinical picture is entirely consistent with this diagnosis and gas exchange is maintained, management with cool mist at home is appropriate. Rapid deterioration is unusual in viral croup; however, if obstruction is prolonged or becomes unusually severe, racemic epinephrine aerosols, hospitalization for careful observation, a brief course of corticosteroid therapy, and, rarely, endotracheal intubation may be required. ⋯ Chronic stridor in infancy most often represents laryngomalacia, a developmental abnormality of the laryngeal cartilage which usually resolves by the second year of life and rarely requires specific treatment. Other causes of chronic stridor in childhood include subglottic hemangioma, vocal cord paralysis, and a long list of abnormalities. In the older child with chronic stridor or in the infant whose clinical picture is unusual for laryngomalacia, airway roentgenograms, barium studies, or laryngoscopy/bronchoscopy should be obtained to establish the definitive diagnosis.

Thirteen cases of epiglottitis are reviewed in this paper. Fever and respiratory distress were the most common presenting symptoms. ⋯ Epiglottitis must be distinguished from viral croup and other causes of upper airway obstruction so that prompt treatment can be instituted. A suggested protocol for management of epiglottitis emphasizes the importance of establishing an artificial airway and administering intravenous antibiotics effective against Hemophilus influenzae type B.
