Occupational exposure and sarcoidosis: a case-control study in three countries.

Background: Preceding studies of environmental and occupational risk factors of sarcoidosis yielded inconsistent findings.

Aims: We aimed to ascertain the occupational risk factors for sarcoidosis in a case-control study.

Methods: A total of 237 sarcoidosis patients with a histologically confirmed diagnosis were matched with 474 controls for sex and age (median 49, interquartile range 37; 60 years) recruited from the university hospitals and outpatient centres in Belarus, Kazakhstan and the Russian Federation.

Occupation and chronic obstructive pulmonary disease in Minsk tractor plant workers.

Background: The aim of this study was to measure the association of exposure to dust at workplace with COPD using objective methods of exposure and outcome classification.

Methods: Forced expiratory volume in one second (FEV ) to forced vital capacity (FVC) <70%; FVC below LLN, and FEV below LLN from the annual screening of Minsk Tractor Plant workers (N = 458) were tested for predictors in an adjusted logistic regression model.

Results: In a regression model, adjusted for pack-years of smoking, age, sex, and work duration, work in highly exposed workplaces was associated with FEV /FVC<70% (odds ratio (OR) 2.

[Prevention and treatment of early complications of surgical treatment of peptic ulcer].

An experience with the operative treatment of 1620 patients has shown that incidence of postoperative complications can be reduced by using active aspiration of the gastric stump content, early intestinal feeding, autohemotransfusions for the substitution of the intraoperative blood loss.
