RESUMO
Objective: To determine the level of knowledge and awareness of hepatitis-B infection among students of a public sector university
Study Design: A cross-sectional observational study
Place and Duration: The study was conducted among students of Center for Physical Education Health and Sports Science, University of Sindh, Jamshoro from 1[st] July to 31[st] December 2013
Methodology: Our tool of data collection was a self-administered questionnaire which assessed basic knowledge of hepatitis B, its modes of transmission, prevention, treatment, sequel and practices and attitudes towards patients with HBV infection. The questionnaire was distributed to the students in the class and they were asked to fill it according to their knowledge without guessing. Data gathered was analyzed by SPSS V. 18
Results: A total of 100 students with mean age 21 years [SD +/- 1.524] took part in this survey. Majority of our students have heard about hepatitis [95%] and a large number of them knew that blood transfusion and re use of syringes [78%] are the main sources of transmission. Interestingly, a reasonable number of students [32%] thought hepatitis B could spread through hug, cough and sneeze of a patient. About half of them were aware that a vaccine is available against HBV. Approximately 70% of the group believed that sterilized syringes and screened blood for HBV should be used to prevent these infections. The mean scores were 66.1%, 42% and 65.4% regarding basic knowledge, transmission and practices about hepatitis, respectively
Conclusion: Student's level of knowledge and awareness about hepatitis B was lacking. They had some misconceptions about disease transmission and treatment which has to be addressed
RESUMO
To compare the frequency of surgical site infection in patients undergoing delayed primary closure [DPC] with those undergoing primary closure [PC] of surgical wounds after abdominal surgery for perforated appendix, perforated duodenal ulcer and ileal perforation. This quasi-experimental study was carried out at Surgical Unit I at Benazir Bhutto Hospital from January 2011 to December 2011. Patients undergoing contaminated abdominal surgery including perforated appendix, duodenal perforation and ileal perforations were recruited through the emergency department. The study included 86 patients, 43 in the primary closure [PC] and 43 in delayed primary closure[DPC] groups. They were followed for evidence of surgical site infection [SSI] for 30 days. Out of 86 patients 43 [50%] had ileal perforation, 26 [30.2%] had duodenal perforation and 17[19.8%] had appendicular perforation. The mean age was 28.9 +/- 8.7 years. 32 [37.2%] were males and 54[62.8%] were females. Both groups were similar with respect to age, gender distribution and indication for surgery. SSI was diagnosed in 19.8% patients. 30.2% in the PC group and 9.3% in the DPC group developed SSI. Hence significantly greater proportion of PC group patients developed SSI as compared to DPC patients; p=0.015. The severity if infection [superficial, deep or organ space] was not significantly different between the PC and DPC groups; p= 0.378. Significantly greater wound dehiscence was encountered in PC group; p=0.011. There frequency of SSI was significantly lower after delayed primary closure of contaminated wounds as compared to primary closure
