o The HIV epidemic in Malaysia is slowing down but has now spread to spouses and sexual partners of traditional at risk populations, via heterosexual transmission. o The WHO 2009 guideline advocates starting HAART at CD4 level of 350 cells/mm3, marking a significant departure from starting at CD4 level of 200 cells/mm3 previously. o The WHO 2009 guideline recommended replacing stavudine with either zidovudine or tenofovir as part of the first line HAART regimen due to the former’s adverse effects. o Early detection of HIV infection and earlier initiation of HAART translates into better quality of life and lower risk of Tuberculosis co-infection. o Earlier detection of HIV infection requires picking up on subtle signs of the infection as well as employing a host of available diagnostic tests in cases where HIV infection is strongly suspected. o HIV test should be offered as a part of a routine health check screening. This facilitates early detection of HIV infection and early referral to the hospital for further management. o Collaboration and communications with non-governmental organizations involved in care of HIV infected people can be a good mean of providing support and counselling to newly diagnosed HIV infected individuals. o Asymptomatic undiagnosed HIV infected patients may pose a risk for disease transmission to health care workers in the primary care setting. Steps must be taken to minimize the risk of transmission and easy access to post-exposure prophylaxis. o The primary care physician should be well versed with the many possible drug interactions between HAART and other commonly used medications for other illnesses in order to avoid potentially fatal adverse reactions or treatment failure in patients taking HAART.

A 19-year-old man presented with sudden onset of right eye ptosis, diplopia and giddiness. He had no previous medical illnesses with negative history of exertional dyspnoea, epistaxis, haemoptysis, palpitations, chest pain and chronic cough. Examination revealed central cyanosis, digital clubbing, polycythaemia, partial ptosis of right eye, diplopia on right gaze and dilated right pupil. Examination of the chest revealed pectus excavatum but no cardiac murmurs were heard. Investigations revealed a solitary right pulmonary arteriovenous malformation with two feeder vessels which were successfully embolized surgically.

This study assessed the effectiveness of education reforms on student-reported learning outcomes at the end of the 5-year medical school (M5) and 1-year internship (HO) in 2006, 2007 and 2008. A self-administered anonymous survey with 17 learning outcomes assessed, derived from Harden's Three-Circle Outcomes Model for outcomes-based education, was administered to 683 students at the end of medical school (M5) and internship (HO) from 2006, 2007 and 2008. We identified learning outcomes which changed significantly for internship (Cohorts A, B and C) and medical school (Cohorts B, C and D) between cohorts from 2006 to 2008, and compared learning outcomes between medical school and internship within cohorts (i.e. Cohort B which was M5 in 2006 and HO in 2007; Cohort C which was M5 in 2007 and HO in 2008). The proportion of students who agreed that medical school helped them achieve learning outcomes increased significantly from 2006 to 2008 for 15 out of 17 learning outcomes assessed. The proportion of students who agreed that internship helped them achieve learning outcomes increased significantly from 2006 to 2008 for 6 learning outcomes assessed. For Cohorts B and C, internship was more effective than medical school in achieving 8 learning outcomes. Cohort C reported that internship was more effective than medical school in 3 additional learning outcomes than Cohort B: patient management, humility and dedication. We conclude that a successful journey of education reform is an ongoing process that needs to comprehensively address multifaceted components such as faculty, administration and curriculum.

Ceramides are associated with metabolic complications including diabetic nephropathy in patients with diabetes. Recent studies have reported that podocytes play a pivotal role in the progression of diabetic nephropathy. Also, mitochondrial dysfunction is known to be an early event in podocyte injury. Thus, we tested the hypothesis that ceramide accumulation in podocytes induces mitochondrial damage through reactive oxygen species (ROS) production in patients with diabetic nephropathy.

Introduction: Current literature reports varied significance of ulnar styloid fractures (USF) associated with distal radius fractures. Our study assesses the role of ulnar styloid fractures and fragment size in surgically managed distal radius fractures. Materials and methods: We reviewed patients who underwent surgical fixation of distal radius fractures between January 2004 to June 2006. Patients were divided into those with (Group 1) and without (Group 0) USFs. Post-operative radiographic parameters, clinical outcomes and overall wrist function were analysed. Outcomes included ulnar-sided wrist pain, extensor carpi ulnaris (ECU) tendinitis, triangular fibrocartilage complex (TFCC) grind test, distal radioulnar joint (DRUJ) instability and pain. Overall wrist function was assessed with range of motion and Disabilities of the Arm, Shoulder and Hand (DASH) score. Results: Our study cohort included 31 males and 23 females, and 38.9% of these patients had concomitant USFs. There was no difference in terms of demographic data and fracture configuration between groups. Radiographic parameters were similar, except for palmar tilt, which was significantly higher in Group 1 (4.6º vs 9.4º, p=0.047). At 24 months, there were no differences in clinical outcomes and overall wrist function. A sub-group analysis showed that mean USF fragment size was larger in patients with a positive TFCC grind test (3.9mm vs 7.3mm, p=0.033). Conclusion: The presence of USFs in surgically managed distal radius fractures does not compromise clinical and functional outcome. Similarly, the size of USFs does not impact clinical and functional outcome but is associated with the presence of a positive TFCC grind test.
