Abstract: Dermatitis from 2-chloromethyl-4-phenyl-6-chloroquinazoline-3-oxide, an intermediate product in the preparation of chlorodiazepoxide, is described in 29 workers at a pharmaceutical plant. All were patch test positive to quinazoline oxide (1%) and six to 0.05%. In most patients, the face was earlier and more severely involved than the hands. Some were sensitized even if they did not have much contact with it, doing such work as washing the clothing of other workers, or working at a distance of 100 m from the production line building.

Abstract: This article describes the immunologic and pulmonary abnormalities and the chemical composition of pleural effusion fluid in a patient with intestinal lymphangiectasia as they are effected by therapeutic measures during a 7-year period. Lymphedema was first noticed in the patient at 3 years of age, and pleural effusions developed 7 years later. Thoracentesis demonstrated that the right pleural fluid was yellow, clear, and had the composition of lymph. The left pleural fluid was milky and had a higher triglyceride and lymphocyte content than the right pleural fluid. Complete removal of pleural fluid transiently increased total lung capacity to a maximum of 52% predicted. Strict dietary management with a low-fat and high-protein diet resulted in a transient partial reversal of circulating lymphopenia and low T cell concentration. This was accompanied by a decrease in lymphocyte and T cell concentration in the pleural fluid. Unstimulated mononuclear cells from pleural fluid synthesized increased amounts of DNA, and added mitogens or antigens further increased DNA synthesis. Dietary therapy had a minimal effect on this DNA synthesis. Despite circulating hypogammaglobulinemia, normal antibody activity was detected. The proportion of B cells in pleural fluid was greater than that in the circulation, and dietary therapy did not alter this difference. Pulmonary physiology improved during the initial 9-month period of diet therapy, but then the rate of fluid accumulation increased, causing respiratory compromise. Stability was achieved by a right-sided pleurodesis, followed 18 months later by a left pleurodesis with the addition of a shunt to provide internal lymph drainage.

Abstract: The microbial flora of recurrently inflamed tonsils removed from 25 children with recurrent episodes of tonsillar pharyngitis were compared to flora of tonsils removed from 23 adults suffering from similar illness. More bacterial isolates per tonsil were recovered in adults (10.2 per tonsil) than in children (8.4 per tonsil). The difference between these groups was due to a higher recovery rate in adults of Bacteroides melaninogenicus group (1.6 isolates per adult, 0.8 per child) and Bacteroides fragilis group (0.4 per adult, 0.2 per child). Conversely, Group A beta-hemolytic streptococci were isolated in seven (28%) children as compared to their isolation in one (4%) adult. More isolates of beta-lactamase-producing organisms (BLPO) per tonsil were recovered in adults. Forty-three BLPO were detected in 21 (91%) of the 23 tonsils removed from adults (1.9 isolates per patient) as compared to 31 isolates in 16 (64%) of the 25 tonsils removed from children (1.2 isolates per patient) (P = 0.04). These findings suggest that the etiology of recurrent tonsillitis in adults may differ from that in children. The differences in the tonsillar flora may be due to the effect of many more courses of antimicrobials given over the years to adults and the changes in tonsillar tissue that occur in this age group.
