BACKGROUNDComputer-based testing (CBT) has become increasingly popular as a testing modality in under- and postgraduate medical education. Since 2004, our medical school has utilised CBT to conduct 2 papers for the third- and final-year assessments - Paper 3, with 30 multiple choice questions featuring clinical vignettes, and the modified essay question (MEQ) paper.

AIMSTo obtain feedback from final-year students on their preferred mode of testing for Paper 3 and MEQ components of the Medicine track examination, and the reasons underlying their preferences.

METHODSAn online survey was carried out on 213 final-year undergraduates, in which they were asked to provide feedback on Paper 3 and MEQ papers. Students were asked if they thought that the CBT format was preferable to the pen-and-paper (PNP) format for Paper 3 and the MEQ, and why.

RESULTSOne hundred and fourteen out of 213 (53.5%) students completed the online survey. For Paper 3, 91 (79.8%) felt that CBT was preferable to PNP, 11 (9.6%) preferred the PNP format and 12 (10.5%) were unsure. For the MEQ, 62 (54.4%) preferred CBT over PNP, 30 (26.3%) preferred the PNP format and 22 (19.3%) were unsure. Reasons given to explain preference for CBT over PNP for Paper 3 included independence from seating position, better image quality (as images were shown on personal computer screens instead of projected onto a common screen) and the fact that CBT allowed them to proceed at their own pace. For the MEQ, better image quality, neater answer scripts and better indication of answer length in CBT format were cited as reasons for their preference.

CONCLUSIONSOur survey indicated that whereas the majority of students preferred CBT over PNP for Paper 3, a smaller margin had the same preference for the MEQ.

INTRODUCTIONThe management of psychogenic movement disorders is fraught with difficulties. Empathy and a non-judgmental manner are essential in dealing with patients, and a neurobiological explanation of the symptoms may help to foster trust, acceptance, understanding and recovery.

CLINICAL PICTUREWe report a 17-year-old Chinese girl with psychogenic blepharospasm. Her parents refused psychotherapy and pharmacotherapy.

TREATMENT AND OUTCOMEPlacebo therapy (with parental consent) was prescribed with favourable results.

CONCLUSIONWe examine the ethical considerations for and against placebo therapy, and explore the role of placebo therapy in the management of psychogenic movement disorders.

BACKGROUND AND AIMIntravenously-administered tissue plasminogen activator (IV-TPA) induces thrombolysis and remains the only FDA-approved therapy for acute ischaemic stroke. IV-TPA thrombolysis has been approved recently in Singapore for acute stroke. Continuous exposure of clot to 2-MHz pulsed-wave transcranial Doppler (TCD) ultrasound during IV-TPA infusion is known to augment thrombolysis. We aimed to determine the feasibility, safety and efficacy of ultrasound-assisted thrombolysis in acute ischaemic stroke in Singapore.

SUBJECTS AND METHODSConsecutive patients with acute ischaemic stroke due to intracranial arterial-occlusions were treated with standard IV-tPA and continuously monitored with 2-MHz TCD according to the CLOTBUST-trial protocol. Arterial recanalisation was determined with Thrombolysis in Brain Ischemia (TIBI) flow-grading system. Safety and efficacy of ultrasoundassisted thrombolysis were assessed by rates of symptomatic intracranial haemorrhage (sICH) and functional recovery at 1 month, respectively.

RESULTSFive consecutive patients (mean age 58 years, 3 men and 3 of Chinese ethnicity) were included. Mean time elapsed between symptom onset and presentation to emergency room was 98 minutes (range, 50 to 135 minutes) while the mean time interval between symptom onset to IV-TPA bolus was 144 minutes (range, 125 to 180 minutes). Partial or complete recanalisation with reduction in the stroke severity was noted in 4 out of the 5 patients during IV-TPA infusion (mean change in NIHSS = 4 points; range 2 to 8 points). None of our patients developed sICH while 4 patients demonstrated good functional outcome at 1 month.

CONCLUSIONSOur preliminary study demonstrates the feasibility, safety and efficacy of ultrasound-assisted thrombolysis in acute ischaemic stroke in Singapore. Continuous TCD-monitoring during IV-TPA infusion provides real-time information, enhances thrombolysis and improves functional outcomes in acute ischaemic stroke.

BACKGROUND: Depression is a recognized complication of lung cancer underreported in developing countries such as Malaysia. Treating and identifying depression in cancer patients increases survival and quality of life. Our objectives are to study prevalence of depressive symptoms in newly diagnosed lung carcinoma, and examine the relationship of depressive symptoms with other influencing risk factors. METHODS: A 2-year, cross sectional study February 2015–February 2017, was conducted at Hospital Tengku Ampuan Afzan, and Penang General Hospital. One hundred and three patients with newly diagnosed, biopsy confirmed primary lung carcinoma were recruited. Self-rated patient's identification sheet, validated Center for Epidemiologic Studies Depression (CES-D), and Dukes University Religion Index score from three different main languages were used. RESULTS: Prevalence of current depressive symptoms (CES-D total score ≥16) is 37.9%. The result suggests prevalence of those at high risk of moderate to major depression, may need treatment. Multivariate analysis reveals those with good Eastern Cooperation Oncology Group factor (η2=0.24, p<0.001) married (η2=0.14, p<0.001) with intrinsic religiosity (IR) (η2=0.07, p<0.02) are more resistant to depression. CONCLUSION: One in three of lung carcinoma patients, are at increased risk for depression. Clinicians should be aware that risk is highest in those with poor performance status, single, and with poor IR. We suggest routine screening of depression symptoms as it is feasible, to be performed during a regular clinic visit with immediate referral to psychiatrist when indicated.

Chorinic hepatitis B virus (CHB) infection is a serious problem that affects over 300 million people worldwide and is highly prevalent in the Asia Pacific region. In the Philippines an estimate 7.3 million Filipinos or 16.7% of adults are chronically infected with HBV, more than twice the average prevalence in the Western Pacific region.

In view of the above, the Hepatology Society of the Philippines (HSP) embarked on the development of consensus statements on the management of hepatitis B with the primary objectives of standardizing approach to management, empowering other physicians involved in the management of hepatitis B and advancing treatment subsidy by the Philippine Health Insurance Corporation (PhilHealth).

The local guidelines include screening and vaccination general management, indications for assessment of fibrosis in those who did not meet treatment criteria. indications for treatment, on-treatment and post-treatment monitoring and duration of antiviral treatment. Recommendations on the management of antiviral drug resistance, management of special populations including patients with concurrent HIV or hepatitis C infection, women of child-bearing age (pregnancy and breastfeeding), patients with decompensated liver disease, patients receiving immunosuppressive medications or chemotherapy and patients in the setting of hepatocellular carcinoma are also included. However, the guidelines did not include management for patients with liver and other solid organ transplantation, patients on renal replacement therapy, and children.

The consensus statements will be amended accordingly as new therapies become available.

INTRODUCTIONPatients with POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal or M-protein and skin changes) syndrome exhibit a wide range of clinical manifestations and are often seen by a variety of specialists prior to diagnosis.

CLINICAL PICTUREWe describe a case of POEMS syndrome that first presented with significant neuropathy but progressed to develop further manifestations of the condition, including marked gastrointestinal symptoms.

TREATMENTThe patient was commenced on localised radiotherapy and chemotherapy in addition to immunomodulatory therapy for the neuropathy.

CONCLUSIONWe highlight several learning points that may benefit physicians from varied specialties. This case is also unique for its marked gastrointestinal manifestation. To our knowledge, this is the second reported case in the literature with this feature.
