[Visits to the doctor because of illness or injury of the students of vocational schools who consume or do not consume psychoactive substances (comparative aspects)].

AIM: To elucidate what impact has the use of different narcotic drugs, alcohol and tobacco on the health of students and the risk of injuries. MATERIAL AND METHODS: We carried out a questionnaire survey of the first year students from all six vocational schools of Klaipeda (Lithuania) in 2004, 2006 and 2008. A total of 912 students (507 boys and 405 girls, mean age 17.5 years) were surveyed with an anonymous questionnaire. The findings were analysed with computer soft SPSS (SPSS 16.0 for Windows). RESULTS: The results showed that the use of any psychoactive substances is damaging to health, especially injection and club narcotic drugs. Adolescents addicted to any psychoactive substances more often than non-addicts visited doctor due to illness or injury during the last 12 months. CONCLUSION: Adolescents on illegal drugs, especially boys on injectable narcotic drugs and girls on club drugs were at twice higher risk for disease or injury (odds ratio--OR--3.39, 95% confidence interval--CI--1.25 to 9.19, p = 0.016 and OR--2.38, CI--1.35 to 4.20, p = 0.003, respectively). Tobacco and alcohol consumption did not significantly increase this risk with the exception of tobacco smoking girls. We think it happened because these two addictions are widely spread among large part of the boys from the vocational schools.

Measurement of the muon capture rate in hydrogen gas and determination of the proton's pseudoscalar coupling gP.

The rate of nuclear muon capture by the proton has been measured using a new technique based on a time projection chamber operating in ultraclean, deuterium-depleted hydrogen gas, which is key to avoiding uncertainties from muonic molecule formation. The capture rate from the hyperfine singlet ground state of the microp atom was obtained from the difference between the micro(-) disappearance rate in hydrogen and the world average for the micro(+) decay rate, yielding Lambda(S)=725.0+/-17.4 s(-1), from which the induced pseudoscalar coupling of the nucleon, g(P)(q(2)=-0.88m(2)(micro))=7.3+/-1.1, is extracted.

[The clinico-microbiological and epidemiological aspects of hospital infections in a surgical clinic]. / Kliniko-mikrobiologicheskie i épidemiologicheskie aspekty gospital'nykh infektsii v khirurgicheskoi klinike.

Complex clinical and microbiological and epidemiological study of specificity of hospital infections was conducted in surgical clinics of Military and Medical Academy. Analysis of the materials obtained has permitted to develop the classification of agents of modern hospital surgical infections, to study the variety and specificity of forming of microorganism hospital strains. To optimize the system of sanitary and epidemiological inspection on hospital infections and to improve their prophylaxis it is proposed to introduce into the practice of bacteriological laboratories of military medical and prophylactic institutions the quantitative microbiological examinations of clinical material. Besides it is reasonable to have in the stuff of multipurpose military hospitals the post of hospital epidemiologist trained in the actual problems of clinical microbiology, hospital hygiene and surgical infection.
