ABSTRACT
The objectives of this study were to determine the characteristics of medical students and graduates interested in choosing psychiatry as a career and the obstacles in choosing this field of medicine. Two private and two public medical institutes were surveyed from June 2007 to August 2007. A self-administered questionnaire was distributed to third, fourth and final year students and to medical graduates doing their internship in these four medical institutes. A total of 909 medical students and graduates participated in the study. Seventeen percent of participants responded positively regarding their interest in psychiatry as a career. Significantly higher proportion belonged to private medical institutes (14% vs. 24%, P-value =0.001). There was no significant difference in reporting interest for psychiatry in regard to age, sex, year in medical school and whether or not the participant had done a psychiatry ward rotation. However significantly higher proportion of participants (22%, n=43) were reporting their interest in the field of psychiatry who had done more than a month long psychiatry ward rotation as compared to those participants (14%, n=54) with less than a month or no psychiatry rotation (P-value=0.01). More students were reporting their interest in psychiatry with a family history of psychiatric illness as compared to without family history (24% vs 16%, P-value=0.03). In conclusion, students and graduates with more than a month long rotation in psychiatry, studying in private medical colleges and with a family history of psychiatric illness were more interested in choosing psychiatry as a career.
ABSTRACT
BACKGROUND: A large number of patients treated at our hospital for endocarditis have negative cultures. Taking into consideration the fact that many of these patients receive antibiotics prior to referral, we decided to study culture-negative endocarditis in Pakistan. METHODS: The medical records of all patients admitted to the Aga Khan University Hospital, Pakistan, for the period from 1988 to 2001, with an underlying diagnosis of infective endocarditis (IE) and negative cultures, were reviewed. RESULTS: Of the 159 patients diagnosed with IE by revised Duke criteria, 86 (54.1%) had persistent negative cultures. More than half of these patients (52%) had received antibiotics before being referred to our center. Patients with culture-negative endocarditis were less likely to be classified as definite endocarditis by revised Duke criteria (p<0.001, 95% CI 0.07-0.3) or to have large vegetations (p=0.021, 95% CI 0.05-0.5), and more likely to have a mitral valve prolapse (p=0.003, 95% CI 1.6-2.3). Definite endocarditis (p=0.042, 95% CI 1.02-7.4), heart failure (p=0.008, 95% CI 1.4-12.7), renal failure (p=0.017, 95% CI 1.16-40.7), embolism (p=0.019, 95% CI 1.2-38.8), and neurological complications (p=0.02, 95% CI 1.16-9.2) were associated with an increased mortality. CONCLUSION: Culture-negative endocarditis is very common among patients with IE in Pakistan. The presentation, laboratory findings, and complications are similar to those for culture-positive endocarditis. It is postulated that previous antibiotic treatment is the most common cause of culture-negative endocarditis in our hospital.
