    26 cases of congenital hypothyroidism were diagnosed at the Penang General Hospital from 1979 to 1993. Therewere 19 femalesand7males, thefemaletomaleratiowas2 .7 : 1. All three main ethnic groups were almost equally afflicted (10 Chinese,8Malays,8 Indians). The mean age at diagnosis was 15.8 months (range 21 days — 9 years) and only 11 (42.3%) patients were diagnosed within thefirst three months of life. 19 (73.7%) patients were diagnosed within thefirstyear and 7 (26.3%) after the firstyear. The correct referral diagnosis was made in less than half (n = 11) of the patients, with a mean of 2.3 doctors being consulted prior to the diagnosis. The five most common clinical features were coarse facies (n = 22), dry skin (n = 22), macroglossia (n = 21), lethargy (n = 20) and constipation (n = 19). The develop-ment quotient was appropriate for chronologi-cal age in less than one third (n = 8) of patients while the school performance was at least average in only less than one third (n = 5) of school-goers (n = 16). The mean (SD) T4 at diagnosis was 23.7 (12.2) nmollL while the mean (SD) TSH at diagnosis was 72.7 (37.0) mUIL. In the light of these clinical findings, screening for congenital hypothyroidism with a view to early diagnosis and prompt treatment are strongly recommended.

    Objective: This case report highlights the complexity of eating disorder in schizophrenia and outlines the diagnostic dilemma and challenges associated with the treatment. Methods: We report a 13 years old female with early onset schizophrenia who developed anorexic symptoms and binge eating. Her eating disturbances worsened after olanzapine was commenced. Results: A combination of pharmacological and psychosocial intervention led to remission of schizophrenia co-morbid with eating disorder NOS. Conclusion: Co-morbid diagnosis of schizophrenia and eating disorder is not uncommon. Early diagnosis and evidence-based intervention are imperative as untreated illness greatly impacts the developmental trajectory of young people. Meeting family’s needs improves family functioning which in turn improves patient’s outcome. ASEAN Journal of Psychiatry, Vol. 15 (1): January - June 2014: 101-105.

    Two EU directives which are RoHS and WEEE have restricted the usage of certain hazardous substances in
    electrical and electronic equipment. This has led to the introduction of green compound which is halogen free. The
    non-halogenated molding compound with different recipes was developed by compound manufacturers without
    compromising the reliability performance of electronic packages. The focus, often, has been on product reliability
    performance while qualifying new materials which overlook relevant safety and health concerns that might incur
    during the production stage. This paper is intended to study the forming of crystalline deposits which are found at
    the exhaust inlet of the Post Mold Cure Oven (PMC) arising from the usage of this green compound. The writers will
    investigate the underlying reasons and the impact on the work environment and the potential risk on health. From the
    initial evaluation result, the writers have indentified Compound A as the cause of this deposition. Data analyzed from
    the Thermo-Gravimetric Analysis (TGA) revealed higher weight loss which was 0.26% for compound A compared to
    other green compounds which are also used. Differential Scanning Calorimetric (DSC) test shows melting temperature
    of crystallized particle at 139°C while cold crystallization temperature at 80°C. The temperature in the interior of the
    oven is 180°C while the temperature at the exhaust inlet which is exposed to room temperature, and thus, providing
    the opportunity for this deposition. Further study carried out using Fourier Transform Infrared (FTIR) spectroscopy
    on one of the ingredient of the green compound (material C) observed a 95% spectrum matching compared to the
    crystallized particle. Material C is a catalyst added to the mold compound for epoxy-phenolic reaction. It is also
    considered to have the capability to enhance flame retardation. This paper will discuss in detail the characteristics of
    Compound A green compound and its impact on human and environment.

    Language is essential for communication. People who are involved in cross cultural communication have to be bilingual in order to interact with people from a different language background (Blackwell. Woolard, K. (2005). Bilingualism opens up various new pathways of thoughts, expressions, and it helps to reduce misunderstanding in interactions (Hidayat, T. 2012). The purpose of this review is to find out how code-switching plays a vital role in language communication especially in the social media such as Facebook, Twitter, SMS and Chat. This study reviewed fifteen journal articles to examine the ways code-switching was used. The review was to discover social phenomena and authentic identities of social actors. The study discovered that code-switching has been used widely to unmask bilinguals’ cultural background and group identity during online communication via Facebook. Finally, code-switching can be used to obtain positive feelings to the interlocutor, which here was combined with introducing humour as an in-group marker, quoting, and to some extent topic specificity as well as possible vocabulary limitation in one language or the other, in the online conversation by bilinguals such as to express group solidarity.

    This article describes a case of Serotonin syndrome (SS), which developed in
    a patient with treatment resistant schizophrenia post-hemi colectomy. Patient
    was a 38-year-old, male with treatment resistant schizophrenia who
    developed septic shock secondary to ischemic sigmoid volvulus, complicated
    with nosocomial pneumonia and surgical site infection post-operation.
    Antipsychotics (haloperidol and amisulpiride) was reinitiated a week postoperation
    when his medical condition was stabilized as patient began to show
    symptoms of psychosis. Haloperidol was later switched to olanzapine as he
    was still agitated and disturbed. Fluvoxamine 50mg was added as he
    displayed hair-pulling behavior. Clopixol accuphase and parental sedation
    with midazolam and phenergen was given as adjunctive management for
    agitation. Several days after, he became more restless. Central nervous
    system examination revealed rigidity, tremors, hyperreflexia and clonus.
    Discontinuation of fluvoxamine and amisulpiride with reduction of
    olanzapine to 20mg ON resulted in full neurologic recovery within the first 24
    hours. It was not well understood how this patient developed serotonin
    syndrome despite him on low dose of fluvoxamine. Clinicians should be
    aware of risk of serotonin syndrome when adding serotonergic agents to
    antipsychotics especially in patients’ post-hemi colectomy.

    Background: House-officers and medical officers are at
    the forefront during medical emergencies in the ward
    and casualty which impose cognitive, communication,
    social and system challenges and yet, training in this
    area is commonly lacking. A workshop was conducted
    using simulation to provide training on some acute
    medical emergencies like cord prolapse, post- partum
    haemorrhage with collapse, poly-trauma and acute
    exacerbation of asthma.

    Objective: To determine the effectiveness of simulation
    in developing competency in managing selected clinical
    emergencies.

    Methodology: There were 22 participants consisting
    of house-officers, junior medical officers and nursing
    clinical instructors. Only doctors were included in
    the study. Four medical emergencies were chosen viz.:
    Cord prolapse; post- partum haemorrhage with collapse;
    poly-trauma and acute exacerbation of asthma. The
    simulated sessions were conducted using high fidelity
    manikins and simulated patients. Simulated patients
    were trained and moulage was applied accordingly. The
    skills stations were on airway equipment and techniques
    of application, latest cardiac life support algorithm and
    hands on chest compression using manikins.

    Results: A 5 point Likert scale used to rate the
    sessions. The skills station had 65% (n=13) rating as
    excellent and 35% (n=7) good. The skills simulation
    was rated excellent by 75% (n=15) and good by 25%
    (n=5) of participants. Verbal feedback was that it was
    very refreshing, informative, and helpful in terms of
    improving their skills.

    Conclusion: The simulated skills training for the junior
    doctors was very well received and maybe beneficial for
    work preparedness and in the long run address patient
    safety.

    Canarium odontophyllum Miq. fruit, popularly recognized as dabai fruit in Sarawak, is a
    seasonal fruit found in the tropical rainforest of East Malaysia. A dabai fruit can be divided into
    several anatomical parts, and different parts of the fruit have different valuable phytochemicals. Due
    to the lack of promotion, dabai fruit is viewed as nutritionally inferior fruit by the public. On the
    contrary, the fruit is rich in nutrients such as protein, fat, carbohydrates, sodium, calcium and iron.
    Many phytochemicals have been detected from different parts of dabai fruit, and these molecules have
    been linked to beneficial properties such as hypolipidemic, anti-atherosclerotic, anti-cholinesterase,
    antimicrobial and potentially anti-diabetic. The aim of this article is to review research studies on this
    fruit in order to provide adequate baseline information for commercial exploitation as well as for
    future studies.

    Inter-simple sequence repeats (ISSRs) are regions in the genome flanked by microsatellite sequences.
    PCR amplification of these regions using a single primer yields multiple amplification products that can
    be used as a dominant multilocus marker system for the study of genetic variation in various organisms.
    ISSR markers are easy to use, low-cost, and methodologically less demanding compared to other
    dominant markers, making it an ideal genetic marker for beginners and for organisms whose genetic
    information is lacking. Here, we comment upon some of the intricacies often overlooked in designing an
    ISSR experiment, clarify some misconceptions, and provide recommendations on using ISSR markers
    in genetic variation studies.

    Highly weathered basaltic rock was exposed at PSK profile of Kuantan, Segamat Highway. The weathering profile from fresh rock soil can be observed at PKJ profile at Kg. Jabi Quarry. Twelve rock and soil samples from PSK profile and thirteen samples from PKJ profile have been collected for geochemical analysis. The objective of the analysis is to establish the behaviour of several major and trace elements in the weathering profile of the basaltic rock. The samples were analysed by XRF and XRD techniques. Petrographic study was done on fresh rock samples and concretions. The concentration of major elements (TiO2, Al2O3 and Fe2O3) appear to be increased with the increasing of the degree of weathering whereas the concentration of SiO2 and CaO are decreased. There is a clear correlation between Fe2O3 + Al2O3 with L.O.I as well as between Fe2O3 with Al2O3. Behaviour of the trace elements (Ni, Co, Cr and Zn) against the weathering process are totally different. The secondary minerals (kaolinite, nactire, geothite, hematite and gibbsite) appear to control the behaviour of the major and trace elements.
    Batuan basalt yang terluluhawa sepenuhnya telah dicerap di lokaliti PSK Lebuhraya Segamat-Kuantan. Profil luluhawa yang boleh dilihat perubahan daripada batuan segar hingga tanih didapati di lokaliti PKJ Kuari Kg. Jabi. Dua contoh profil dengan masing-masing 12 sampel dan 13 sample tanih telah dikaji untuk menentukan perlakuan beberapa unsur major dan unsur surih batuan basalt yang terluluhawa. Kaedah analisis yang digunakan ialah pendarflour sinar-X (XRF) dan pembelauan sinar-X (XRF). Kajian petrografi pula dibuat pada sampel batuan segar dan sampel konkresi. Nilai unsur major TiO2, Al2O3 dan Fe2O3 bertambah dengan bertambahnya darjah luluhawa manakala SiO2 dan CaO menyusut. Hubungan korelasi Fe2O3 + Al2O3 dengan L.O.I dan Fe2O3 denagn Al2O3 adalah jelas. Unsur surih nikel (Ni) kobalt (Co), kromium (Cr) dan zink (Zn) mempunyai perlakuan yang berbeza-beza dengan luluhawa. Perlakuan yang ditunjukkan oleh unsur major dan surih tersebut dikawal oleh mineral sekunder (koalinit, nakrit, geotit, hematit dan gibsit).

    Bacillus pumilis was isolated and identified from limestone and the ability towards carbon dioxide (CO) sequestration was demonstrated. B . pumilus (S3 SC_1), isolated from Gua Tempurung, Gopeng, Perak was able to form calcite in the presence of calcium ions. B. pumilus was successfully characterized by using conventional biochemical characterization and 16s rDNA sequencing. Three types of experimental systems with B. pumilus, without B. pumilus and without continuous supply of CO2 with the presence of B. pumilus which could produce extracellular carbonic were studied to determine the effects of bacterially produced carbonic anhydrase (CA) by B. pumilus in removing CO2 as calcite. Through our current study, CO2 sequestration ability of B . pumilus was proven.

    Only a handful of countries use earprints for forensic investigation and the practice of using earprints as an evidence in a court of law remains arguable. This study was conducted to determine if an earprint could be traced back to an individual and show significant difference when compared to an earprint from another and to identify the difference(s) between genders. The earprints of 50 males and 50 females between the ages of 18-40 were collected and analysed. The digital overlay method was employed and measurements (angles and lengths) were compared between prints. The overlay method as well as the measurements show clear difference(s) among individuals and prove that each ear is unique and that earprints can be used for individual identification. Although the measurements showed some differences in the tragus angle, helix-tragus length as well as antitragus-helix length between the genders, the differences were too small to bear any significance.

    Spontaneous rupture of uterine fibroid is rarely encountered. We present a case of a 31-year-old who presented with acute abdominal pain at 9 weeks postpartum. On examination, the abdomen had diffuse tenderness, with rebound tenderness in the suprapubic area and in both iliac fossae. On ultrasonography, a 12.7 × 8.6 × 8.9-cm sized hyperechoic mass was visible on the posterior wall of the uterus. A large amount of fluid was visible in the paracolic gutters and the Pouch of Douglas (POD). The patient underwent an exploratory laparotomy. A ruptured, cystic degenerated uterine fibroid with active bleeding was found, as well as approximately half a liter of free, bloodstained peritoneal fluid and pus. Myomectomy was performed, followed by evacuation of the fluid and clots. The patient's postoperative course was uneventful. In conclusion, preoperative diagnosis of a perforated, uterine fibroid with spontaneous intra-abdominal hemorrhage is difficult; exploratory laparotomy is both diagnostic and therapeutic in this rare, life-threatening condition.
