Having studied in vitro the effect of UVR on the two species of microorganisms which are most common as agents of surgical infection, we realized the closer the distance from the irradiation lamp and the longer the irradiation time, the stronger the bactericidal effect of UVR. When UVR is applied for air disinfection within the distance of more than 2 meters from the sunlamp irradiation, it can also reduce significantly the number of microorganisms in the air. It is due to the fact that there is a continuous air exchange between the upper and the lower part of the room. Previous studies and the experiments on petri dishes show that the use of UVR for cleaning infected wounds and preventing infection is an effective, simple and safe measure

157 samples were isolated from infectious operating lesion they were cultured into Biomerieus culture media and undergone an antibiogramme on Muller-Hilton medium. S. aureus and E. coli are the most common organisms, which are isolated. Occasional infections occurred increasingly.

Having studied the results, we realised: -Incidence of nasal S.aureus carriage in the surgical patients is 36.1%, of skin S. aureus carriage is 9.6%. - Incidence of S. aureus infection of incision on patients who carry this microorganism in nose is 8.2% and do not carry it is 2.3%. - S. aureus patient ‘s nasal carriage is really the risk factor for transmission of this microoganism to skin and causing infection of incision, including the clean operations. - Treating infectious locations and resolving state of S. aureus patient’ nasal S. aureus carriage will reduce the infected incisions from endogenous flora.

OBJECTIVES: The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcohol-related disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online. METHODS: An online cross-sectional study was conducted with 1,080 Vietnamese youths. A standardized questionnaire was used. Respondent-driven sampling was applied to recruit participants. Multivariate logistic and Tobit regressions were utilized to identify the associated factors. RESULTS: About 59.5% of the males and 12.7% of the total youths declared that they were actively using alcohol. From the total sample, a cumulative total of 32.3% of the participants were drinking alcohol, with 21.8% and 25.0% of the participants being classified as drinking hazardously and binge drinkers, respectively. The majority of the participants (60.7%) were in the pre-contemplative stage. CONCLUSIONS: A high prevalence of hazardous drinking was recognized among online Vietnamese youths. In addition, we found relationships between alcohol use disorder and other addictive disorders, such as tobacco smoking and water-pipe usage. Our results highlighted that the majority of the individuals are not receptive to the idea of changing their alcohol habits, and this would imply that there ought to be more government effort towards the implementation of effective alcohol control policies.
