We report a 35 year-old Iranian female who presented with a sudden onset of left sided hemiparesis associated with temporary loss of consciousness of about 3 minutes. Neurological examination revealed a power of 0/5 over the left upper/lower limbs but reflexes were normal and plantar reflex was downgoing and equivocal. A computed tomography scan was done and it revealed mild bilateral frontal atrophy and a temporal arachnoid cyst which was decidedly an incidental finding and it did not have any relation to the clinical presentation. Electroencephalogram and other laboratory findings were all normal. When the psychiatric team interviewed her, it was revealed that the patient had recently experienced a major stressful event just prior to the hemiparesis. On further interview, the patient had complained of delusions of persecution, delusions of reference and also auditory hallucinations for approximately a year prior to admission. There have been only a spatter of reports of conversion symptoms seen in patients with schizophrenia and this is such a case.
Background: The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) developed by the World Health Organization is designed to identify individuals at risk for alcohol use problems and provide brief intervention.
Objectives: To evaluate the validity and reliability of the ASSIST in Malaysia’s official language, the Bahasa Malay, among a group of alcohol users. The study also aimed to assess the impact of alcohol on the quality of life of patients.
Methods: The final version of ASSIST-M was administered to 51 patients who were identified as alcohol users and attended the outpatient psychiatric clinic during a three-month period from September to November of 2012. Patients completed ASSIST, ASSIST-M, Mini-International Neuropsychiatric Interview (M.I.N.I.), Malay version of The Alcohol Use Disorders Identification Test (AUDIT-M), CAGE Assessment for Alcohol Abuse (CAGE), and the World Health Organization Quality of Life Scale-Brief-Malay version (WHOQoL-Brief-M). Statistical procedures were performed to assess the reliability and validity of the ASSIST-M.
Results: Factor analysis of ASSIST-M yielded one factor similar to the factor structure of the English version. The Cronbach’s α coefficient of ASSIST-M was 0.80. The parallel reliability of the ASSIST-M was high with the intra-class correlation (ICC) of 0.96 (P< 0.01). The test–retest reliability of the ASSIST-M after the 1-week interval was high with the ICC of 0.94(P< 0.01). The ASSIST-M was positively correlated with the AUDIT-M (r =0.67, p <0 .01) and the CAGE (r=0. 57, p < 0.01). ASSIST-M score showed a negative and statistically significant relationships with the physical (r= -0 .28, p < 0.01) and social relationship (r= -0.37, p<0.01) subscales of the WHOQoL-Brief-M. The optimal cutoff point for ASSIST-M for alcohol use disorder was more than 14 with the with a sensitivity of 84.21 %, specificity of 84.38 %, positive predictive value (PPV) of 76.19% and negative predictive value (NPV) of 90%.
Conclusions/Importance: The ASSIST-M displayed a fair psychometric performance in assessing alcohol use disorder in Malaysia.

Objective: To study the prevalence of social anxiety problem and potential risk factors that may be associated with social anxiety among medical students. Methods: Social Phobia Inventory (SPIN) and a questionnaire assessing gender, religion, number of siblings, type of school and partner status were given to 167 final year medical students. Results: There were 101 respondents of which 56% of the medical students scored > 19 in the Social Phobia Inventory (SPIN) suggesting that they were having social anxiety problem. None of the variables analysed were significantly associated with social anxiety. Conclusion: More than half of the medical students have significant social anxiety symptoms. No specific variables were found to be significantly associated with those at risk of developing social anxiety disorder.
This paper addresses the growth of nano-structured MgZnO thin films by sol-gel spin coating method which will be used as a template layer to grow carbon nanotubes. The nano-structured MgZnO films were deposited on platinized (100) silicon substrates. In this work, we focused on the effect of aging and Mg content on the film structure and resistivity. Sols with Mg content of 10, 30 and 50 at.% were subjected to aging times of between 3 to 240 hours. Results from scanning (SEM) and field emission scanning electron (FESEM) microscopes and surface profiler (SP) showed that the sol aging increased the thickness, grain size and surface roughness for aging up to 240 hours. The energy dispersive analysis by X-ray (EDAX) confirmed the element of Mg in the ZnO films. The electrical resistivity also increased with aging time as confirmed by four point probe method. The results suggest that appropriate aging of the sol is important for improving physical quality and electrical performance of MgZnO thin films derived from sol-gel technique.
