BackgroundAccidental exposure to blood and body fluids is frequent among health care workers. They are at high risk of nosocomial transmission of blood borne pathogens due to injuries caused by used sharps. We are reporting impact of surveillance and educational program on the rate of needle stick injuries among health care workers at a tertiary care hospital in Pakistan.MethodsAt Aga Khan University Hospital sharp injuries are reported to infection control office. To reduce these incidents a quality improvement project was inducted in the year 2005. Health care workers were educated; surveillance data from 2002 to 2007 was analyzed and compared with various risk factors.ResultsDuring study period 1382 incidents were reported. Junior doctors sustained highest number of injuries (n = 394; 28.5%) followed by registered nurses (n = 283; 20.4%). Highest number of incidents was reported during blood collection (19%). An increasing trend was observed in the pre intervention years (2002–04). However noticeable fall was noted in the post intervention period that is in year 2006 and 2007. Major decline was noted among nurses (from 13 to 5 NSI/100 FTE/year). By relating and comparing the rates with various activities directly linked with the use of syringes a significant reduction in incidents were found including; hospital admissions (p-value 0.01), surgeries and procedures performed (p = 0.01), specimens collected in the laboratory (p = 0.001) and patients visits in clinics (p = 0.01).ConclusionWe report significant reduction in needle stick injuries especially during post intervention study period. This is being achieved by constant emphasis on improving awareness by regular educational sessions, implemented as a quality improvement project.

Multidrug-resistant tuberculosis (MDR-TB) is a possible threat to global tuberculosis control. Despite a disease prevalence of 263/100 000 population Pakistan lacks information on prevalence of drug resistant TB. Our objective was to estimate prevalence of MDR and associated risk factors in patients with pulmonary tuberculosis in Karachi. Six hundred and forty consenting adult patients were enrolled from field clinics from July 2006 to August 2008 through passive case finding. Prevalence of MDR-TB with 95% confidence interval (CI) was calculated with Epi-Info. Logistic Regression analyses were performed for risk factors associated with MDR. Overall MDR rate was 5.0%, 95% CI: 3.3-6.6% (untreated 2.3%, treated 17.9%). Mean age was 32.5 (+/-15.6) years and there were 292 (45.6%) females and 348 (54.4%) males. Factors independently associated with MDR were: female gender (OR 3.12; 95% CI: 1.40-6.91), and prior history of incomplete treatment (OR 10.1; 95% CI: 4.71-21.64). Ethnic groups at higher risk for MDR included Sindhis (OR 4.5; 95% CI: 1.42-14.71) and Pashtoons (OR 3.6, 95% CI: 1.12-11.62). This study reports an overall MDR rate of 5.0% in our study population. It further highlights the need for MDR prevention through re-focusing Directly Observed Treatment, Short-course DOTS delivery with emphasis on women and certain high risk sub groups.

Objectives Men who have sex with men (MSM) and transgender individuals are at higher risk of genital warts and anal cancer due to sexually transmitted human papillomavirus infection. This study explores MSM and transgender women’s perceptions of Human papillomavirus (HPV) infection and HPV prevention strategies (screening and vaccination) in Pakistan. Design A qualitative study using focus group discussions (FGD) with self-identified MSM, male sex workers and transgender women were conducted between March 2019 to August 2019 in Karachi, Pakistan. Methods Participants were recruited from community-based organization (CBO) working for MSM and transgender women. A total of 38 men and 10 transgender women took part in 6 FGDs. Discussions were recorded, translated, transcribed verbatim and analyzed using content analysis. Results Three themes were identified from the emerging analysis. These are, 1) Knowledge and risk perceptions about STIs and HPV, 2) Beliefs and attitudes towards HPV prevention, 3) Participant’s recommendations for HPV vaccination and anal Pap screening. Participants described lack of knowledge of HPV and its health consequences as HIV is the only focus of attention of the government and the local CBOs. None of participants had heard about HPV prevention including vaccination and anal Pap screening for men but expressed a positive attitude towards prevention. Genital warts and anal cancer were perceived as severe potential consequences of a known risk behaviors. All participants stated they would be interested in taking an HPV vaccine but acknowledged that the provision of services for sexually transmitted infections (STI) are inadequate to meet the needs of key populations and are not prioritized by the government. The main perceived barriers to access HPV prevention included cost and challenges to access public health care services or openly discussing one’s sexual orientation with health care providers. Participants generally preferred the CBO for more professional, unbiased staff attitudes that respect patients’ integrity, confidentiality and privacy. Most participants thought that in case the government is non-cooperative, CBOs should work in the interest of HPV eradication and generate funds through international funding. Conclusions The findings from this study can help public health policy and researchers to understand this minority’s perspective on HPV prevention. Given the low level of knowledge about HPV infection and its negative health consequences there is a need of HPV education combined with STI education and awareness through HPV brochures to educate the target population effectively.

Background: Shigellosis is a common cause of morbidity, especially in the very young and old, in developing countries. The disease is treated with antibiotics. Surveillance of antimicrobial resistance trends is essential owing to the global emergence of antimicrobial resistance. Methodology: The study involved 1,573 isolates of Shigella species (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007) that were analyzed for trends in antimicrobial resistance. Results: The majority of the specimens (1046; 66.5%) were from the pediatric population, and of these 887 (84.8%) were under 5 years of age (p = 0.001). S. flexineri was the most frequent species (54.5%) isolated. Isolation of S. sonnei increased from 15.4 % (1996) to 39% (2007) (p = 0.001). Although none of the isolates was found sensitive to all the antibiotics tested, 58% (n =9 07) were resistant to ampicillin and 85% (n = 1,338) were resistant to trimethoprim-sulfamethoxazole (TMP-SMX). Out of a total of 198 (12.6%) nalidixic acid resistant isolates, 6 (3.0%) were also resistant to ofloxacin. Overall 1.7 % of isolates were resistant to ofloxacin, 2.4% to ceftriaxone and 2.3% were resistant to combination of ampicillin, nalidixic acid and TMP-SMX. Conclusion: Ofloxacin is still an effective drug for treatment of acute shigellosis in Pakistan. Emergence of resistance to ceftriaxone in Shigella may have grave implications in treatment of severe shigellosis in very young patients.
