A comparison of course-related stressors in undergraduate problem-based learning (PBL) versus non-PBL medical programmes

Background: Medical students report high levels of stress related to their medical training as well as to other personal and financial factors. The aim of this study is to investigate whether there are differences in course-related stressors reported by medical students on undergraduate problem-based learning (PBL) and non-PBL programmes in the UK. Method: A cross-sectional study of second-year medical students in two UK medical schools (one PBL and one non-PBL programme) was conducted. A 16-question self-report questionnaire, derived from the Perceived Medical Student Stress Scale and the Higher Education Stress Inventory, was used to measure course-related stressors. Following univariate analysis of each stressor between groups, multivariate logistic regression was used to determine which stressors were the best predictors of each course type, while controlling for socio-demographic differences between the groups. Results: A total of 280 students responded. Compared to the non-PBL students (N = 197), the PBL students (N = 83) were significantly more likely to agree that: they did not know what the faculty expected of them (Odds Ratio (OR) = 0.38, p = 0.03); there were too many small group sessions facilitated only by students resulting in an unclear curriculum (OR = 0.04, p < 0.0001); and that there was a lack of opportunity to explore academic subjects of interest (OR = 0.40, p = 0.02). They were significantly more likely to disagree that: there was a lack of encouragement from teachers (OR = 3.11, p = 0.02); and that the medical course fostered a sense of anonymity and feelings of isolation amongst students (OR = 3.42, p = 0.008). Conclusion: There are significant differences in the perceived course-related stressors affecting medical students on PBL and non-PBL programmes. Course designers and student support services should therefore tailor their work to minimise, or help students cope with, the specific stressors on each course type to ensure optimum learning and wellbeing among our future doctors

Retinal changes in visceral leishmaniasis by retinal photography

Background: In visceral leishmaniasis (VL), retinal changes have previously been noted but not described in detail and their clinical and pathological significance are unknown. A prospective observational study was undertaken in Mymensingh, Bangladesh aiming to describe in detail visible changes in the retina in unselected patients with VL. Methods: Patients underwent assessment of visual function, indirect and direct ophthalmoscopy and portable retinal photography. The photographs were assessed by masked observers including assessment for vessel tortuosity using a semi-automated system. Results: 30 patients with VL were enrolled, of whom 6 (20%) had abnormalities. These included 5 with focal retinal whitening, 2 with cotton wool spots, 2 with haemorrhages, as well as increased vessel tortuosity. Visual function was preserved. Conclusions: These changes suggest a previously unrecognized retinal vasculopathy. An inflammatory aetiology is plausible such as a subclinical retinal vasculitis, possibly with altered local microvascular autoregulation, and warrants further investigation. </p

Mycobacterium shimoidei: an uncommon non-tuberculous infection in a UK patient.

We present the case of a 69-year-old man with significant respiratory comorbidities who presented with slow growing pulmonary nodules which cavitated. Subsequent sputum sampling grew Mycobacterium shimoidei, a non-tuberculous mycobacterium species and an uncommon cause of infection in the UK. We describe the diagnostic process and subsequent treatment regimen

Pyrexia of unknown origin: inferior vena cava agenesis.

A 26-year-old woman presented with a 5-day history of fever after returning from Bali. She denied sexual contact abroad. On examination, there was suprapubic tenderness and a widespread maculopapular rash. Malaria serology was negative and blood tests were normal except for an elevated C reactive protein. Treatment was initially with ceftriaxone, metronidazole and doxycycline, but her symptoms failed to improve. A CT pelvis suggested a possible tubo-ovarian abscess, a suspected inferior vena cava (IVC) anomaly and left internal iliac/femoral venous thrombosis. A gynaecology review demonstrated left tubo-ovarian tenderness and fullness. An MRI suggested pelvic inflammatory disease and thrombophlebitis affecting the pelvic veins; deep vein thrombosis (DVT) treatment was commenced. Further family history revealed thrombosis throughout multiple generations. Further imaging analysis demonstrated agenesis of the IVC with compensatory dilation of pelvic collaterals and an acute DVT of the deep pelvic venous system. The patient was discharged with direct oral anticoagulant therapy
