Isolation for the control of infection in skin wards.

An isolation policy in a hospital for skin diseases is reported. Patients carrying penicillin- and tetracycline-resistant organisms were to be isolated in single rooms, though barrier nursing was not practised. The policy failed because the single beds rapidly became blocked with long-stay patients and because even in a single-bed unit patients acquired staphylococci within 3-7 days of admission.

Pulmonary artery pressure and alveolar gas exchange in man during acclimatization to 12,470 ft.

Pulmonary hemodynamics and gas exchange were studied in four physicians during 72 hr acclimatization to 12,470 ft. Pulmonary catheters were left in three subjects for 72 hr. Resting mean pulmonary arterial pressure (PAP) rose progressively during the first 24 hr from 10.

Infections in a hospital for patients with diseases of the skin.

Studies on infections in a hospital for diseases of the skin are described. Patients were shown to acquire staphylococci in the groin and on the chest at about the same rate as in the nose. In contrast to surgical wards, many staphylococci were resistant to tetracycline but sensitive to penicillin.

Effect of ear-defenders (ear-muffs) on the localization of sound.

260-265. In a laboratory study we examined the influence of ear-defenders (ear-muffs), of a type used in industry, on a localization task using the binaural (diotic) presentation of a 1 KHz pure tone under anechoic conditions. Our subjects were 15 foundry workers, none of whom had ever used hearing protection.
