BackgroundA training physician has his first interaction with a pharmaceutical representative during medical school. Medical students are often provided with small gifts such as pens, calendars and books, as well as free lunches as part of drug promotion offers. Ethical impact of these transactions as perceived by young medical students has not been investigated in Pakistan before. This study aimed to assess the association of socio-demographic variables with the attitudes of medical students towards pharmaceutical companies and their incentives.MethodsAs part of a cross-sectional survey, a validated questionnaire previously used for assessing attitude of medical students towards pharmaceutical industry, was modified, pre-tested and distributed among consenting clinical year students at DUHS and AKU. Questions included acceptability of pharmaceutically sponsored gifts, events and tuition fee, and their impact on future prescription. Responses were graded as agree, disagree or neutral which were then scored according to the AMSA guidelines of ethical conduct.ResultsOut of a total of 353 targeted students 303 responded, corresponding to a response rate of 85.8%. Responses indicated that 42.7% students believed in no interaction with drug companies during medical school. However, 81% of students favored pharmaceutical sponsorship of student-body events/seminars at medical colleges. More than one-third of the students were comfortable receiving gifts from drug companies. Overall, the results of this study offer an interesting comparison between the students of a private medical school (AKU) and a public medical school (DUHS); AKU students exhibited a greater degree of mistrust towards drug information provided by pharmaceutical companies compared to DUHS students (p = 0.040). Furthermore, when asked if there was a need to incorporate guidelines in the undergraduate curriculum with regard to interaction with drug companies, 84.2% students at AKU agreed, compared to 54.9% at DUHS. Medical student Attitude Scores are more or less similar to each other independent of their various demographical differences.ConclusionThis study highlights that medical students in our population have a high level of acceptability towards incentives offered by pharmaceutical industry and that formal guidance regarding the subject should be incorporated into medical curriculum.

Background. Hip fracture surgery is a common procedure, and the geriatric population with its multiple comorbid conditions is at most at risk of developing anesthesia-related complications. Data on the impact of type anesthesia on postoperative morbidity and mortality is limited. The effects of regional and general anesthesia on postoperative outcomes need to be clearly elucidated. Methods. In this study, all patients who underwent dynamic hip screw (DHS) fixation for intertrochanteric fractures, between January 2005 and December 2010, at the Aga Khan University Hospital, were included. Patients were divided into two groups; group A included those patients who received general anesthesia, and group B consisted of patients who had received regional anesthesia. The two groups were compared for differences in morbidity, mortality, and intraoperative complications based on the type of anesthesia administered. Results. During this period, 194 patients underwent DHS fixation. One hundred and seven patients received general anesthesia whereas eighty-seven patients received regional anesthesia. The mean operative time was significantly lower in the group receiving regional anesthesia (1.25 ± 0.39 hrs) as compared to those who received general anesthesia (1.54 ± 0.6 hrs) (P < 0.05). There were no statistically significant differences in the rates of wound infections, length of hospital stay, postoperative ambulation status, intraoperative blood loss, postoperative complications, and mortality between the regional and general anesthesia groups. Conclusion. Even though administration of regional anesthesia was positively correlated with shorter operative duration, the type of anesthesia was not found to affect surgical outcomes in the two study groups. Based on these results, we recommend that anesthesia should be tailored to individual patient requirements.

IntroductionSideroblastic cardiomyopathy secondary to repeated blood transfusions is a feared complication in thalassaemia. Control of myocardial iron is thus becoming the cornerstone of thalassaemia management. Recent evidence suggests a role for L-type Ca2+ channels in mediating iron uptake by the heart. Blocking the cellular iron uptake through these channels may add to the benefit of therapy to standard chelation in reducing myocardial iron. We aim to determine the efficacy of amlodipine (a calcium channel blocker) as an adjunct to standard aggressive chelation in retarding myocardial iron deposition in thalassaemics with or without cardiomyopathy.OutcomesThe primary outcome is to compare the efficacy of amlodipine+chelation (intervention) versus standard chelation (control) in retarding myocardial iron deposition. Secondary outcomes include the effect of amlodipine therapy on systolic and diastolic function, strain and strain rate and liver iron content.Methods and analysisThis is a single-centre, parallel-group, prospective randomised control trial. Twenty patients will be randomised in a 1:1 allocation ratio into the intervention and control arms. In addition to conventional echocardiography, MRI T2* values for assessment of cardiac and liver iron load will be obtained at baseline and at 6 and 12 months. Cardiac T2* will be reported as the geometric mean and per cent coefficient of variation, and an increase in cardiac T2* values from baseline will be used as an end point to compare the efficacy of therapy. A p Value of <0.05 will be considered significant.Study settingDepartment of Pediatric and Child Health, Aga Khan University Hospital, Karachi, Pakistan.Ethics and disseminationThis study has been approved by the Ethics Review Committee and Clinical Trials Unit at The Aga Khan University with respect to scientific content and compliance with applicable research and human subjects regulations. Findings will be reported through scientific publications and research conferences and project summary papers for participants.Trial registration numberClinicalTrials.Gov. Registration no: NCT02065492.

BackgroundRoad traffic injuries (RTIs) commonly affect the younger population in low- and-middle-income countries. School children may be educated about road safety using storybooks with colorful pictures, which tends to increase the child’s interest in the text. Therefore, this study assessed the use of bilingual pictorial storybooks to improve RTI prevention knowledge among school children.MethodsThis pretest-posttest study was conducted in eight public and nine private schools of Karachi, Pakistan, between February to May 2015. Children in grades four and five were enrolled at baseline (n = 410). The intervention was an interactive discussion about RTI prevention using a bilingual (Urdu and English) pictorial storybook. A baseline test was conducted to assess children’s pre-existing knowledge about RTI prevention followed by administration of the intervention. Two posttests were conducted: first immediately after the intervention, and second after 2 months. Test scores were analyzed using McNemar test and paired sample t-test.ResultsThere were 57% girls and 55% public school students; age range 8–16 years. Compared to the overall baseline score (5.1 ± 1.4), the number of correct answers increased in both subsequent tests (5.9 ± 1.2 and 6.1 ± 1.1 respectively, p-value < 0.001). Statistically significant improvement in mean scores was observed based on gender, grades and school type over time (p-value < 0.001).ConclusionDiscussions using bilingual pictorial storybooks helped primary school children in Pakistan grasp knowledge of RTI prevention. RTI education sessions may be incorporated into school curricula using storybooks as teaching tools. Potential exists to create similar models for other developing countries by translating the storybooks into local languages.Electronic supplementary materialThe online version of this article (10.1186/s12887-018-0982-5) contains supplementary material, which is available to authorized users.
