Musculoskeletal pain and its associated risk factors among medical students of a public sector University in Karachi, Pakistan.

OBJECTIVE: To assess the frequency and anatomical distribution of musculoskeletal pain and its related risk factors. METHODS: This cross-sectional study was conducted at the Dow Medical College, Karachi, from September to November 2016, and comprised medical students. A self-administered questionnaire was filled out by the participants. Data was analysed using SPSS 17. RESULTS: Of the 360 participants, 268(74.4%)and 140(38.9%)students reported having musculoskeletal pain in at least one of the body sites in the past 12 months and in the past seven days, respectively. Self-reported mental stress (p=0.01) and history of trauma in the neck, shoulder or lower back (p=0.002) were the most significant predictors of musculoskeletal pain during the past seven days. Age, body mass index, gender, academic year, family history of musculoskeletal disorders, hours of clinical practice per day, hours of study per day, smoking and exercise had no significant relation with musculoskeletal pain in neck, shoulder or lower back (p>0.05 each). The use of computer/laptop for more than three hours per day had an increased occurrence of neck pain (p=0.03).. CONCLUSIONS: There was a significant risk of musculoskeletal pain for medical students.

Attitudes of Pakistani and Pakistani heritage medical students regarding professionalism at a medical college in Karachi, Pakistan.

BACKGROUND: An increased interest in professionalism has been reported in the field of medical education due to concerns regarding deterioration of humanism and professional values in the teaching and practice of medicine. The primary aim of this study was to assess attitudes of Pakistani and Pakistani heritage students at a medical college in Pakistan about important elements of professionalism that an ideal medical doctor should possess. A further objective of the study was to determine students' preferred ways of learning professionalism. METHODS: A written survey was distributed to undergraduate medical students at a public sector medical college at Karachi, Pakistan in 2011. Using the Penn State College of Medicine (PSCOM) Professionalism Questionnaire, attitudes of medical students of semester 1, 5, and 8 regarding professionalism were assessed anonymously. RESULTS: The mean age of the students was 21.11 ± 2.72 years. Forty-three percent of the respondents were male. Forty percent of the students held Pakistani citizenship. Thirty-five percent students were US citizens with Pakistani parents and twenty-five percent were Pakistani heritage students that had dual citizenships. No significant differences in the elements of professionalism (Accountability, Altruism, Duty, Excellence, Honesty & Integrity and Respect) mean scores or in the overall mean score of professionalism among the various classes were found. The total overall Cronbach alpha value for all elements of the professionalism in the selected classes was above 0.9. The most preferred methods for learning professionalism were role modeling by faculty, case based scenarios and role plays. CONCLUSION: The students rated all the attributes of professionalism as important and there was no difference across the study years. The overall internal consistency of each element of professionalism was high in different classes. Faculty role models, case based scenarios and role plays may be used to teach professionalism. As a great majority of students were having a Pakistani heritage rather than complete Pakistani born and bred background, hence findings of the survey may not be taken as representative of typical Pakistani medical students.

Knowledge of emergency contraception among women of childbearing age at a teaching hospital of Karachi.

OBJECTIVES: To assess knowledge and attitudes about Emergency Contraception among women of childbearing age in Karachi, Pakistan. METHODS: A questionnaire based survey was conducted on 400 married women, attending the family practice clinics at a teaching hospital in Karachi, Pakistan from July to December 2006. Questionnaire was administered to women at the family practice clinic-seeking level of knowledge of emergency contraception (EC) and attitudes towards its use, Ethical requirements of informed consent and confidentiality were ensured Data was entered into Epi data and analyzed in SPSS. RESULTS: Eighty-eight percent of women were not aware of EC. 83% were housewives. Only a small number (11.5%) ever used EC to prevent pregnancy, out of those, the correct timing of effectiveness of post-coital pill was known to only 40% of women while none of these women were aware of the existence of Intra Uterine Contraceptive Device (IUCD) insertion as an option for EC About 50% of women identified general practitioners or family medicine clinics as their main sources of knowledge about EC. Increased advertising was considered desirable by 72% while 37% considered over the counter availability of EC pill desirable and only 36% of women were uncomfortable to use EC because of religious reasons. CONCLUSION: EC has a potential to offer women an important option for fertility control. Lack of women's knowledge about EC use and availability may account in part for its limited use. There is a need to improve women's education about EC. The primary health care providers can play a major role in informing their patients about emergency contraception.

Non-fatal limb injuries in motorbike accidents.

OBJECTIVE: To determine frequency and pattern of non-fatal limb injuries in motorbike accidents victims. STUDY DESIGN: Cross-sectional observational study. PLACE AND DURATION OF STUDY: Study was conducted at Jinnah Postgraduate Medical Centre (JPMC), Karachi, from October 2006 to March 2007. METHODOLOGY: Trained data collectors prospectively collected data from the emergency department of JPMC, Karachi using structured pre-tested questionnaires. All motorbike accident victims presented to Emergency department with single or multiple bone injury in body extremities were included. Head injury patients who had first presented to neuro-surgery department were excluded. Motorbike accident victims with soft tissue injuries were also excluded from this study. Chisquare test was applied to find out statistical significance at 95% confidence level. P-value < 0.05 was considered as significant. RESULTS: A total of 137 (39%) patients presented with tibial injury among the study sample of 348 patients, which was significantly higher than the bone injuries of the body part (p<0.001). Out of those, in 26% of patients, fibula was also involved along with tibia fracture. Other bone injuries included femur (16%), radius (9.2%), humerus (8.3%) and others. Radius was the commonest injured bone and in highest proportion among upper limb injuries (p<0.001). Overall, 66% of the injuries in motorbike involved lower limb fractures. The highest proportion of motorbike accidents were observed on Saturdays (31%). Majority of the accident victims were in the age group between 16 and 30 years (41% accident cases), 27% in age group 30 to 45 years, 15% in 45 to 60 years and 5% in >60 years. Those with less than 15 years accounted for 12% of cases. CONCLUSION: Tibial bone is at the greatest risk in motorbike accidents probably due to its superficiality and exposed position while riding motorbike. Protective measures need to be taken for the prevention of disability associated with lower limb involvement in motorbike accidents.

Cleaning methods for ultrasound probes.

OBJECTIVE: To determine the effectiveness of three different methods of ultrasound probe cleaning for the prevention of nosocomial infections. STUDY DESIGN: Experimental study. PLACE AND DURATION OF STUDY: Radiology Department, the Aga Khan University Hospital, Karachi and Microbiology Department, JPMC, Karachi, from December 2006 to April 2007. PATIENTS AND METHODS: A total of 75 culture swabs from ultrasound probes used for sonographic examinations of different body parts of patients were included in the study. Probes were prospectively randomized into three equal groups with 25 probes in each group. Culture was sent before and after using three different techniques of cleaning ultrasound probe, which included sterilized paper towel, 0.9% saline and swipe over with standard bath soap applied on group A (n=25), group B (n=25) and group C (n=25) respectively. Number of Colony Forming Unit (CFU) of bacteria were calculated on standard agar plate to find out the effectiveness of cleaning methods in reducing bacterial count from the ultrasound probe after the procedures. All samples were tested in single microbiology lab by using same bacterial growth media provided by same manufacturer. Kruskall Wallis, Jonchkheere-Terpstra and Wilcoxon sign rank tests were applied to find out statistical significance. RESULTS: There was a significant reduction in bacterial count after applying either of all three cleaning methods for ultrasound probe compared to count on the probes before cleaning (p<0.001), however, soap cleaning method was the most effective in decreasing bacterial count to the minimum level in comparison to other two methods (p<0.001). The overall reduction in pathogenic bacterial count after performing each cleaning method was 45%, 76% and 98% for paper cleaning, normal saline and soap cleaning method respectively. CONCLUSION: Cleaning ultrasound probe after performing each procedure is a cost-effective practice with potential of reducing nosocomial infections. Soap cleaning technique is the most effective method for reducing bacterial count acquired due to patients' body contact with the ultrasound probes.
