Gallbladder carcinoma - a rare cause of pyloric-duodenal stenosis.

Pyloric duodenal stenosis is usually caused by pyloric, juxtapyloric or duodenal ulcer, or by postbulbar ulcer. Gallbladder cancer (GBC), duodenal diverticula, annular pancreas and superior mesenteric artery syndrome (Wilkie's syndrome) are rare causes of pyloric duodenal stenosis. The case of a 66-year-old female patient is presented.

Nature and prevalence of risk factors associated to type B and C acute viral hepatitis cases in Bucharest, 1998-2000.

The main objective of the study was to calculate and report the prevalence of probable risk factors involved in the transmission of pathogenic agents among type B and C acute viral hepatitis cases confirmed in Bucharest (1998-2000). The standardized values of the risks detected in the 45-180 days preceding the onset of illness suggest that in both types of acute viral hepatitis considered in our study transmission associated to the individuals' behaviour (19.0%-hepatitis B and 20.

Antidiphtheria and antitetanus immunity in various age groups (0-70 yrs) in Romania.

The evaluation of the antidiphtheria and antitetanus immunity level is still a topical question. The paper approaches the study of antidiphtheria and antitetanus immunity on age groups in 3,768 and, respectively, 4,001 subjects. In the studied population, the results of estimating immunity revealed an antidiphtheria percentage of 87.

Drug allergy: incidence in terms of age and some drug allergens.

The authors studied the incidence of drug allergy in 3 groups of subjects. In the first group the incidence was established in terms of the subjects' age: 1.8% in children up to 14 years old (323 subjects), 5.

Investigations upon the incidence of atmospheric fungi in the town of Craiova.

The present investigation was suggested by the fact that bronchial asthma (of all types) presents in Craiova and the district of Dolj a relatively increased incidence which may be correlated with certain findings concerning the incidence of atmospheric fungi in the houses and working places of asthmatic subjects. Petri dishes with Czapek medium were exposed monthly in the open air, in 17 houses of asthmatic subjects and in a large bakery unit. The prevalence of various types of fungi was observed on the culture media and a correlation could be made with the seasons.

[Evolutive peculiarities of streptococcal infections in the year 1980, in the city of Bucharest].

In further investigations on the evolutive trends of the epidemiologic streptococcal process, an extensive epidemiological survey was carried out in prescholar and school communities in the town of Bucharest with a view to applying efficient antiepidemic measures able to limit primary streptococcal infections and prevent late, redoubtable complications. In 1980, in Bucharest, morbidity from scarlet fever was at its lowest level (92.7 per 100,000) during the last 31 years; it was in general benign, affecting especially in the month of March the 5-9 years age group (623.

Atopic and non-atopic sensitivity in a large bakery.

Flour is an allergen which can sensitize either by the digestive or the inhalatory route, particularly those who work with this product. Factors involved occupational four-induced asthma also include various insects and their excreta, fungi and dermato-farinae. In this study, 1303 subjects from a number of bakeries were studied.

[Research on anti-diphtheria immunization in the city of Bucharest].

Biological, sero-epidemiological and bacteriological investigations, carried out in the town of Bucharest for evaluating the present diphtheria vaccination programme showed: -- high anatoxin titers, exceeding the titer considered as protective, in the vaccinates ; -- a concentration of the level of the titers of 1--4 AU/ml, in over 62% of the subjects, which means that the protective titer was exceeded 33 to lucru: -- negative Schick reaction, in the mean 95.06%, in the subjects examined during the 1969--1975 period; -- isolation of the Bacillus diphtheriae in a proportion of 0.08%, none of the toxigenic gravis type.
