Quantitation of nasal secretory IgA by enzyme-linked immunosorbent assay.

A simple and sensitive technique, enzyme-linked immunosorbent assay (ELISA) was used for the quantitation of secretory IgA (sIgA) in order to study the synthesis and transport of sIgA in the nasal secretion from patients with chronic sinusitis. Rough-surface glass beads coated with antisecretory component antibody were employed as the solid phase. The minimal detectable concentration of sIgA was 50 ng/ml in this study. sIgA averaged 226.3 +/- 217.4 mg/dl and total IgA averaged 302.0 +/- 137.5 mg/dl.

A case of subglottic hemangioma: a new technique of surgical removal.

Congenital malformation of the larynx are life-threatening anomaly for newborns and infants. Although tumorous lesions in these malformations (especially subglottic hemangioma) are extremely rare, when they do occur some definitive attempts should be made to treat them in infancy. This report concerns a case of subglottic hemangioma with marked stridor and sternal retractions which had begun in the third month of age in a six month-old male. In the excision of the hemangioma a new technique is employed. That is: the excision through the laryngofissure was made under surgical microscope. Assuming that careful removal of the subepithelial hemangioma and closure of the overylaying epithelia would help to maintain the mucosa and thereby avoid excessive scarring, the hemangiomatous tissue was completely removed while preserving the overlaying epithelial layer.

Immunofluorescence study in purpura pigmentosa chronica.

Purpura pigmentosa chronica comprises a group of vascular disorders of unknown etiology. In biopsied specimens obtained from 8 patients, we observed vascular changes such as fibrinoid degeneration and occlusive damage occasioned by a hyalinized substance as well as swollen endothelia in 3. However, in all biopsied specimens, direct immunofluorescence studies demonstrated depositions of C3 or C1q with or without immunoglobulins, and of fibrin in papillary vessels. These findings suggest the possibility that immunological processes are involved in producing the histopathologic features of this disorder.

Topical heat therapy for cutaneous chromomycosis.

An aged man with a large scaly plaque over the left buttock was successfully treated by local heat therapy using an electric bed-warmer with a surface temperature of 46 degrees C. Clinically, the lesion involuted completely after two months of treatment. This was concomitantly confirmed by histopathological and mycological studies of biopsy specimens obtained from the lesion at an interval of several weeks. The isolated fungus strain of Fonsecaea pedrosol could grow at 37 degrees C on Sabouraud's dextrose agar, but was totally eradicated 24 hours after the culture was incubated at 46 degrees C. We consider that local heat therapy carried out under strict supervision is a quite effective treatment for chromomycosis. Moreover, it can be performed safely and without much discomfort to patients, and can yield satisfactory results in a relatively short time.

Doxapram hydrochloride in the treatment of acute exacerbation of chronic respiratory failure. A patient with four episodes treated without use of a respirator.

A 51-year-old woman with chronic respiratory failure (status after tuberculosis) was given an infusion of doxapram hydrochloride (1 to 2 mg/kg of body weight per hour) for four episodes of acute exacerbation of her condition. Treatment with the drug prevented worsening of hypercapnia in the four episodes, when administration of 24 percent oxygen had occasioned rises in the arterial carbon dioxide tension of 23, 10, 9, and 7 mm Hg.
