Antibiotic-resistant Staphylococcus aureus in dermatology and burn wards.

Staphylococcus aureus isolated between 1967 and 1975 from the nose and skin lesions of patients in dermatology wards and from the burns of patients in a burns unit in Birmingham showed a high incidence of multiple antibiotic-resistant strains in both environments. Over 20% of the strains isolated from patients on admission to the dermatology wards were multiresistant. Resistance to benzylpenicillin, tetracycline, erythromycin, and fusidic acid was common in the dermatology wards; a smaller proportion of strains were resistant to lincomycin, and few (since 1972 none) were resistant to methicillin; resistance to novobiocin and chloramphenicol was uncommon. In the burns unit, fusidic acid resistance was uncommon, but resistance to benzylpenicillin, tetracycline, erythromycin, novobiocin, neomycin, methicilin, and lincomycin was common. Several of the antibiotics to which resistance was common in the burns unit were rarely if ever used there; strains resistant to these antibiotics probably remained common in the ward through the frequent use of other antibiotics, especially erythromycin, to which these strains were also resistant.

Oral prostaglandin E2 for induction of labor at term. II. Comparison of two low-dosage regimens.

Prostaglandin E2 was administered orally for induction of labor in 100 normal term gravidas with two dosage regimens. The data derived were compared with comparable data from gravidas matched with study patients according to prelabor cervical preparation and other relevant obstetric and actuarial features. Analysis of patterns of cervical dilatation and station vs. time was carried out. A dose of 0.5 mg. hourly was found to be effective in inducing labor of good quality with minimal side effects, providing a better balance between efficacy and adverse reactions than the higher dosage level.

Mercuric chloride uptake by eggs of the ricefish and resulting teratogenic effects.

Eggs collected from adult Japanese Medaka were incubated for 16 days in solutions containing 10, 15, 20, and 30 ppb mercury as mercuric chloride. The mean hatchability of control eggs was 46.7 percent. Experimental eggs incubated in 10 ppb and 15 ppb mercury had hatching percentages of 58.3 and 20.8 respectively (Chi Square = 12.8, Pless than.0005). None of the 20 ppb or 30 ppb experimental eggs hatched. Nemorrhaging, blood vessel deterioration and loss of blood cells were observed in 79 percent of the 15 ppb experimental eggs and all the 20 and 30 ppb experimental eggs. Neither the control nor the 10 ppb experimental eggs demonstrated any of these abnormalities. The LC100 for 384 hours was between 20 ppb and 30 ppb. The 10, 15, 20 and 30 ppb experimental eggs concentrated mercury directly from the incubating solution 1,600, 1,900, 2,700, and 1,900 times, respectively. The total concentration of mercury in these eggs after 16 consecutive days was 16,000, 29,000, 54,000, and 56,000 respectively.

Gastric operations and glucose homeostasis. II. glucagon and secretin.

Alimentary hyperglycemia in patients who have undergone gastric operations may be due, in part, to altered intestinal signals for glucose disposition. We measured glucose, immunoreactive insulin (IRI) pancreatic glucagon (IRG), and glucagon-like immunoreactivity (GLI) after oral glucose in patients with prior antrectomy or vagotomy and pyloroplasty and in normal individuals. All subjects had normal assimilation coefficients for intravenous glucose, which suggests that the responsiveness of the pancreatic beta-cells had not been altered by the surgical procedures. The early hyperglycemic response to oral glucose and the associated elevation of plasma GLI were much greater and the IRI levels slightly higher in both experimental groups in comparison to normal subjects. A decrease in the level of IRG, albeit not statistically significant, was noted in all groups after the ingestion of glucose. In gastrectomy patients, secretin infusion during repeated oral glucose tolerance tests partially corrected the hyperglycemia and lowered plasma GLI and IRI levels. The responses of the vagotomy and pyloroplasty patients and of the normal subjects were not altered by secretin infusion. We conclude that the intolerance or oral glucose after gastric surgery may be related to elevated GLI levels, and that the beneficial effect of secretin may be due to its ability to decrease these levels.

Veno-arterial difference in alpha 1 -antitrypsin levels.

alpha(1)-Antitrypsin levels, determined by radial immunodiffusion, were found to be higher in the venous than in the arterial blood of patients with pulmonary infections and in patients with obstructive airflow diseases. Large differences occurred in patients with both abnormalities. No difference was found in patients with other kinds of lung disease or in patients without lung disease. The veno-arterial difference probably occurs as blood passes through the lungs and probably results from alteration of the immunological properties of the alpha(1)-antitrypsin, perhaps by attachment to proteases, rather than absorption into the lung tissue. Further studies are needed to define the diseases in which this antienzyme plays an active part and to determine the mechanisms causing the difference.

Deaf children's processing of auditory, visual, and combined stimuli.

One hundred eighty-four deaf children were presented auditory, visual (speechreading), and combined stimuli. Some subjects showed an enhancement of their processing abilities in the combined mode, some demonstrated no improvement, and others yielded reduced scores. A method of data analysis is proposed which could contribute to a better understanding of a subject's performance.
