Do medical students who claim to be using deep learning strategies perform better at the Forensic Medicine examination.

Literature reveals that frequent use of deep learning strategies and meaning orientation generally relates to academic performance positively, while the reproducing orientation is usually negatively associated with academic performance. The objective of this study was to investigate possible associations between reported learning strategies and performance at different components of the Forensic Medicine examination between two successive batches of medical students at the Faculty of Medicine, University of Peradeniya, Sri Lanka. Reported learning strategies of two successive groups of medical students were measured using the adapted Sri Lankan version of the Inventory of Learning Styles, the Adyayana Rata Prakasha Malawa (ARPM). The inventory scale scores were computed for each student and entered into a data base. The scores for each component of the Forensic Medicine examination namely; essay, multiple choice questions and viva voce and the total score were added to the data base. The Spearman rank correlation test was performed to identify possible associations between learning strategy scores and performance at different components of the examination. The number of respondents was 142 out of 173 of the 2003/2004 (82%) and 107 out of 188 students (57%) of the 2002/ 2003A batches of fourth year medical students having completed three terms of work in Forensic Medicine. Contrary to expectations, the results failed to show a significant association between academic performance and frequent use of deep processing strategies or self regulation. Since examinations drive the learning process it could be that the assessment demands promote the students to use both surface and deep learning strategies to the same extent.

Reliable and easy identification of bacterial acute respiratory infections of childhood.

OBJECTIVES: To identify the causative bacteria in childhood acute respiratory infections (ARI) and to determine the usefulness of pus cell counts in differentiating between pathogenic and commensal bacteria, cultured from nasopharyngeal aspirates. DESIGN: Case control prospective study. SETTING: Outpatients' department and the paediatric unit at General Hospital, Colombo South. SUBJECTS: 200 children under 5 years with cough and difficulty in breathing for less than one week who had no history of antibiotic therapy for the current illness, and 50 healthy controls matched for age and sex. RESULTS: 56.5% of cases had bacterial infections. Branhamella catarrhalis (25%), Haemophilus influenzae (12.5%) and Streptococcus pneumoniae (10.5%) were the major pathogens identified. Pus cell counts were found to be significantly higher in cases than in controls (X2 58.28 df = 1 p < 0.001), and the pathogens were more often associated with pus cell counts of more than 10/field. CONCLUSIONS: 56.5% of children with ARI had bacterial infections. B catarrhalis seems to play a major role in childhood ARI. Examination of nasopharyngeal aspirates is a useful way to identify pathogens, provided microscopic examination for pus cells is performed together with culture.
