Influence of allergy, asthma and hypertension on nasal polyposis.

Arterial hypertension was found in 78 of 224 consecutive patients operated for nasal polyposis. An exacerbated degree of hypertension was significant in groups aged above 50 years. In total, 46% of patients whose nasal polyposis lasted for more than 10 years suffered from hypertension.

Influence of embryonal fusion lines for recurrence of basal cell carcinomas in the head and neck.

A reinvestigation of 171 basal cell carcinomas of the head and neck treated by surgical excision revealed 23 recurrences. Recurrence rate in one group of basal cell carcinomas, situated on embryologic fusion lines, was statistically higher than in other groups of basal cell carcinomas situated on other parts of the face and on the capillitium which served as control. Histopathologic subclassification of the recurrent basal cell carcinomas revealed a higher incidence of nodular type with infiltrative margin and of the infiltrative type.

Incidence and prognosis of acute epiglottitis in children in a Swedish region.

Acute epiglottitis, which is almost exclusively caused by Haemophilus influenzae type b, was studied retrospectively in children 0 to 15 years old in a defined region of southwest Sweden from 1971 through 1980; 211 patients with clinically well-documented acute epiglottitis were found. The age-specific incidence was 14/100,000/year, which was higher than the incidence of H. influenzae meningitis.
