The value of tuberculin skin testing in the diagnosis of active tuberculosis remains uncertain. Interpretation of tuberculin tests would be easier if the tuberculin test profiles in different communities were accurately known. We reviewed 468 Mantoux test reactions in patients coming to Hospital Universiti Sains Malaysia with suspected tuberculosis. Eighty six percent of patients with active tuberculosis had a positive Mantoux test. Forty two percent of the cases of positive Mantoux test did not have evidence of active tuberculosis. Most of these cases had evidence of past infection with tuberculosis. We conclude that Mantoux test is a sensitive but a non-specific test in the diagnosis of active tuberculosis.

Seventy-five adult asthmatic patients with clinical remission underwent spirometry. Only 8.3% of the subjects demonstrated normal spirometry. The others had reduced vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximum mid-expiratory flow rate (MMF) and peak flow rate (PEFR). This study demonstrates that asthma can cause irreversible airflow obstruction and there is a poor relationship between symptoms in asthmatics and their respiratory function test results.

A forty-four year old wife of an alcoholic husband with irregular employment sought repeated medical care for her headache, bodyache, chest pain and alleged falls at home. The family backgrounds of the battered wife and the violent husband, his alcoholism and their financial problems all contributed to the violence in marriage. Their six children had lived in fear and two of them had behaviour problems. Awareness of the multiple problems associated with a battered wife should prompt cooperation between medical, social and other workers involved in the management.

University Hospital to the psychiatric Walk- inClinic
In February to March 1982 at the psychiatric emergency service of the University Hospital, Kuala Lumpur, some data on 491 patients (92% of 531 patients seen) were collected. Two-hundred and eighty-three patients had received psychiatric treatment and 65 had previously received medical treatment. Fifty-three per cent of the patients have schizophrenic disorders, 5.1% had situational reactions and 1.63% had chronic alcoholism. Of the 111 patients presented with either physical complaints or insomnia, eleven of them were admitted to the psychiatric wards. Three-hundred and eleven patients were followed-up in the psychiatric outpatient clinics. The availability of a psychiatric emergency service in a general hospital can contribute towards early psychiatric case findings and preventive Intervention. II provides an opportunity for liaison and consultation with other medical colleagues in the care of patients with physical complaints and attempted suicides.

This study investigated the prevalence and severity of depression, anxiety, and stress and determined the association between various factors, social support, and depression, anxiety, and stress among university healthcare workers in Malaysia after the government lifted the movement control order (MCO) put in place to curb the coronavirus disease 2019 (COVID-19) pandemic. This online, cross-sectional survey recruited 399 participants from two university hospitals, and they were administered a self-reported questionnaire on demographic, personal, and clinical characteristics, as well as COVID-19-related stressors and coping. In addition, they completed the Multidimensional Scale of Perceived Social Support (MSPSS) to measure perceived social support, as well as the 21-item Depression, Anxiety, and Stress Scale (DASS-21) to assess depression, anxiety, and stress. We found that the prevalence rates of depression, anxiety, and stress were 21.8%, 31.6%, and 29.1%, respectively. Participants with moderate to extremely severe depression, anxiety, and stress made up 13.3%, 25.8%, and 8.1% of the sample, respectively. Being single or divorced, fear of frequent exposure to COVID-19 patients, agreeing that the area of living had a high prevalence of COVID-19 cases, uncertainty regarding the prevalence of COVID-19 cases in the area of living, and a history of pre-existing psychiatric illnesses were associated with higher odds of depression, anxiety, and stress. Conversely, having more than three children and greater perceived friend support were associated with lower odds of depression, anxiety, and stress. The prevalence of depression, anxiety, and stress remained elevated even after the MCO was lifted.

The purpose of this study was to evaluate the periodontal status distal to the adjacent second molar following the extraction of a partially or fully impacted mandibular third molar at Klinik Pergigian Pakar Hospital Universiti Sains Malaysia (KPPHUSM) from April of 2008 until June of 2008.This was a prospective study which involved the clinical and radiological study of patients. In this study, convenience sampling method had been used. The sample size was 22 patients aged 18-32 years old with inclusion criteria. The outcomes measured in this study were periodontal pocket depth (PPD), clinical attachment level (CAL) and alveolar bone height (ABH). Subjects were examined at distal surface (disto-buccal, mid-distal and disto-lingual) of second molar for PPD and CAL before and 3 months after the impacted adjacent lower third molar extraction. OPG was taken each before and after the third molar removal. These data were analyzed using SPSS version 16 and Wilcoxon-signed-ranks test was used to compare the PPD, CAL and ABH pre and post operatively. All the results were not significant with p >0.05. For PPD, median = 3mm pre and post extraction. CAL median= 2mm pre and post operatively and ABH median of 3.10mm (before) and 2.8mm (after) the third molar removal. From our study, we concluded that there were no significant changes of PPD, CAL and ABH at distal side of second molar after 3 months of the adjacent impacted lower third molar removal.

Background: The efficacy and acceptance of a low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet in Asian adults with irritable bowel syndrome (IBS) remain uncertain. We aimed to describe our early experience in a single center with a dedicated gastroenterology dietetic service.
Methods: Consecutive patients with IBS referred to our dedicated Dietetic Gastroenterology Clinic between February 2016 and May 2016 were screened. A low FODMAP diet was instituted as per standard protocol. Data on demographic and clinical variables were obtained from patients' records and prospective telephone interviews.
Results: A total of 16 patients, with a median age of 67 ± 13.57 years; female gender n = 10 (62.5%); ethnicity: Chinese n = 8 (50%), Indian n = 5 (31.25%), and Malay n = 3 (18.75%) with IBS, were included in the study. Compliance with the low FODMAP diet was complete in 8 of 16 (50%) patients, partial in 4 of 16 (25%), and 4 of 16 (25%) could not comply with the diet at all. Improvement in symptoms were reported in 11 of 16 (68.8%) patients. Among patients who complied (complete/partial) with the low FODMAP diet, predominant symptom improvement was reported as follows: abdominal pain 3 of 5 (60%), abdominal bloating/distension 7 of 10 (70%), and flatulence 7 of 8 (87.5%). Patients with the IBS-D subtype appeared to have the greatest improvement in stool consistency (87.5% IBS-D vs 12.5% non-IBS-D, P = 0.009).
Conclusion: Based on our pilot observational study of a relatively small sample of Asian IBS patients, compliance with a low FODMAP diet appears to be low. Further larger studies are required to verify our observation.

INTRODUCTION: The aim of this study was to determine the extent to which primary care doctors assessed patients newly diagnosed with hypertension for the risk factors of cardiovascular disease (CVD) during the patients' first clinic visit for hypertension. The study also aimed to examine the trend of assessment for CVD risk factors over a 15-year period.
METHODS: This retrospective study was conducted between January and May 2012. Data was extracted from the paper-based medical records of patients with hypertension using a 1:4 systematic random sampling method. Data collected included CVD risk factors and a history of target organ damage (TOD), which were identified during the patient's first visit to the primary care doctor for hypertension, as well as the results of the physical examinations and investigations performed during the same visit.
RESULTS: A total of 1,060 medical records were reviewed. We found that assessment of CVD risk factors during the first clinic visit for hypertension was poor (5.4%-40.8%). Assessments for a history of TOD were found in only 5.8%-11.8% of the records, and documented physical examinations and investigations for the assessment of TOD and secondary hypertension ranged from 0.1%-63.3%. Over time, there was a decreasing trend in the percentage of documented physical examinations performed, but an increasing trend in the percentage of investigations ordered.
CONCLUSION: There was poor assessment of the patients' CVD risk factors, secondary causes of hypertension and TOD at their first clinic visit for hypertension. The trends observed in the assessment suggest an over-reliance on investigations over clinical examinations.
A retrospective study of 37 cases of multiple myeloma admitted from 1980 to 1987 to the University Hospital Kuala Lumpur, Malaysia, was carried out to analyse the biodata, clinical presentation, laboratory and radiological profiles. The cases were selected after they had satisfied preset diagnostic criteria. The mean age was 60 years. There was no sex or ethnic preponderance. The most common symptom was bone pain. Pallor was detected in 73% of the patients. Haemoglobin was less than 120 g/L in 95%, and ESR was greater than 100 mm/hr in 70% of cases. Bone marrow and trephine biopsies were diagnostically important. Hypercalcaemia occurred in seven cases out of which three were IgA myelomas. Either serum creatinine or blood urea was raised in nearly 50% of cases. The most common heavy chain paraprotein was IgG while Kappa light chain was the commoner light chain type. 86% of cases had osteolytic lesions. These findings are, in general, similar to those of larger studies on multiple myeloma.

A quality assurance exercise for non-insulin dependent diabetes mellitus in the Family Practice Clinic, University Hospital Kuala Lumpur, was conducted using HbA1c as an indicator. We found that about 60% of the 163 patients with non-insulin dependent diabetes mellitus had fair to optimal control. The HbA1c correlated well with fasting and post-prandial blood glucose level (r=0.79 and r=0.54, respectively, p<0.001). The mean HbA1c was significantly higher in Malay compared to the other races, in those with longer duration of diabetes and in patients on two types of oral hypoglycaemic agent.

beta-Lactamases have been identified as the major cause of antimicrobial resistance to beta-lactam antibiotics in Escherichia coli. The activities of ampicillin-sulbactam and amoxicillin-clavulanate as well as a range of beta-lactam antibiotics were studied with 87 clinical E. coli isolates from patients of the University Malaya Medical Center using the disc diffusion technique. Susceptible, intermediate and resistant categories were established based on the diameter of zones of inhibition set by the National Committee for Clinical Laboratory Standards (NCCLS). The isolates were then classified into 6 phenotypes according to the criteria stated in the methodology: S (susceptible to all beta-lactams); TL (resistant to aminopenicillins; amoxicillin-clavulanate susceptible and susceptible or intermediate to ampicillin-sulbactam); TI (resistant to aminopenicillins and ampicillin-sulbactam; susceptible to amoxicilin-clavulanate); TH-IRT (resistant to aminopenicillins; intermediate or resistant to amoxicillin-clavulanate; resistant to ampicillin-sulbactam); ESBL (resistant to aminopenicillins and oxyimino cephalosporins; positive results with the double-disc diffusion test); and CP (resistant to aminopenicillins, beta-lactam-beta-lactamase inhibitor combinations, oxyimino cephalosporins and cephamycins). Results showed that the TL phenotype was the commonest (40.2% of the isolates) followed by S (31%), TH-IRT (16.1%), ESBL and CP (3.4% each) and TI (2.3%). One isolate showed both ESBL and CP phenotypes while two isolates were classified as inconclusive. Representatives from each phenotype were further analysed for the presence of beta-lactamases which revealed a predominance of TEM and SHV enzyme producers. PCR-SSCP analysis of the SHV gene from all the ESBL and CP isolates revealed the predominance of SHV 5-type enzyme which was concurrent with our previous studies.
We conducted a prospective study of 60 patients in a tertiary care referral center to ascertain the status of cell-mediated immunity as determined by delayed hypersensitivity reactions in patients with nasopharyngeal carcinoma (NPC) or allergic rhinitis. Delayed hypersensitivity as detected by Mantoux testing is generally accepted as a reflection of the level of cell-mediated immunoactivity-the less hypersensitivity reaction that occurs, the lower the level of immunoactivity is, and vice versa. Our study population was made up of three groups: 20 newly diagnosed patients with NPC (pretreatment), 20 age- and sex-matched patients with allergic rhinitis, and 20 matched controls without either disease. A negative Mantoux test (0- to 5-mm induration) was seen in 13 patients with NPC (65.0%), in 17 patients with allergic rhinitis (85.0%), and in 16 controls (80.0%); none of these differences was statistically significant. However, it is interesting that while the NPC group had the lowest percentage of negative Mantoux results overall, it had the highest percentage of patients who had no reaction at all (i.e., 0-mm induration); a complete absence of any reaction was seen in 7 of the 13 Mantoux-negative NPC patients (53.8%), compared with 2 of the 17 Mantoux-negative allergic rhinitis patients (11.8%) and 3 of the 16 Mantoux-negative controls (18.8%). An absence of a reaction generally indicates a very limited degree of cell-mediated immunoactivity. Therefore, we conclude that patients with NPC appear to have significantly less cell-mediated immunity than do patients with allergic rhinitis and normal controls; no statistically significant difference was noted between the latter two groups.

AIM: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a recognised cause of severe neonatal hyperbilirubinaemia, and identifying which infants are at risk could optimise care and resources. In this study, we determined if G6PD enzyme activity (EA) and certain gene variants were associated with neonatal hyperbilirubinaemia requiring phototherapy during the first week after birth.
METHODS: Newborn infants with G6PD deficiency and a group with normal results obtained by the fluorescent spot test were selected for analyses of G6PD EA and the 10 commonly encountered G6PD mutations in this region, relating these with whether the infants required phototherapy before discharge from the hospital in the first week.
RESULTS: A total of 222 infants with mean gestation and birth weight of 38.3 ± 1.8 weeks and 3.02 ± 0.48 kg, respectively, were enrolled. Of these, n = 121 were deficient with EA ≤6.76 U/g Hb, and approximately half (43%) received phototherapy in the first week after birth. The mean EA level was 3.7 U/g Hb. The EA had good accuracy in predicting phototherapy use, with area under the receiver-operating-characteristic curve of 0.81 ± 0.05. Infants on phototherapy more commonly displayed World Health Organization Class II mutations (<10% residual EA). Logistic regression analysis showed that deficiency in EA and mutation at c.1388G>A (adjusted odds ratio, 1.5 and 5.7; 95% confidence interval: 1.31-1.76 and 1.30-25.0, respectively) were independent risk factors for phototherapy.
CONCLUSION: Low G6PD EA (<6.76 U/g Hb) and the G6PD gene variant, c.1388G>A, are risk factors for the need of phototherapy in newborn infants during the first week after birth.

BACKGROUND: The causal association between gastro-oesophageal reflux disease (GERD) and difficult-to-control asthma is unclear.
AIM: To determine the prevalence of GERD and response to proton pump inhibitor therapy in patients with difficult-to-control asthma.
METHODS: Consecutive patients with difficult-to-control asthma as defined by persistent and recurrent symptoms despite on optimal asthmatic medications were recruited for the study. GERD was diagnosed by symptoms, gastroscopy and 24-h oesophageal pH monitoring. All patients were prescribed a course of lansoprazole 30 mg daily for 8 weeks. Improvement to treatment was assessed by a change in pulmonary symptom score and also by patient's subjective assessment of improvement.
RESULTS: Seventeen of 30 (56.7%) patients with difficult-to-control asthma were diagnosed with GERD. Pulmonary symptom score improved significantly only in patients with GERD (35.0 to 21.0; P = 0.002). Twelve of 16 (75%) patients with GERD reported an improvement in asthma symptoms; 1 of 11 (9.1%) without GERD reported mild symptom improvement. There was no significant change in peak expiratory flow rate and forced expiratory volume.
CONCLUSIONS: More than half of patients with difficult-to-control asthma were diagnosed with GERD. In these patients the severity of asthma improved significantly with potent acid suppression therapy. This underlines the critical role of acid reflux in this subset of patients with difficult-to-control asthma.

PURPOSE: People with epilepsy (PWE) are negatively prejudiced in their ability to work. This study aimed to examine demographic, clinical and psychological factors associated with employability in PWE.
METHODS: This study recruited epilepsy patients from a neurology clinic in Malaysia. Employability was measured using employment ratio, with a ratio ≥90% (ER90) classified as high employability. Basic demographic data such as age, gender, marital status, religion, education level and household income was collected. Clinical measures consisted of age of seizure onset, seizure frequency, type of epilepsy, aura, polytherapy, nocturnal seizures and seizure control. Psychological measures included Work Self-Determination Index (WSDI), Rosenberg Self-Esteem Scale (SES), and Multidimensional Scale of Perceived Social Support (MSPSS).
RESULTS: Of 146 PWE, 64.4% had high employability. The participants were predominantly female (52%), Chinese (50.7%), single (50%), having tertiary education (55.5%) and focal epilepsy (72.6%). Clinically, only type of epilepsy was significantly correlated to employability of PWE. Employability of PWE was associated with ability to work (indicated by education level, work performance affected by seizures, ability to travel independently and ability to cope with stress at work) and family overprotection. The high employability group was found to have lower self-perceived stigma (ESS), higher self-determined motivation (WSDI), self-esteem (SES) and perceived social support (MSPSS), than the low employability group. Logistic regression analysis showed that tertiary education level (AOR 3.42, CI: 1.46-8.00), higher self-determination (WSDI, AOR 1.09, CI: 1.012-1.17), lower family overprotection (AOR 0.76, CI: 0.61-0.95), and generalised epilepsy (AOR 4.17, CI: 1.37-12.70) were significant predictors for higher employability in PWE.
CONCLUSION: Ability to work (education level), clinical factor (type of epilepsy) and psychological factor (self-determined motivation and family overprotection) were important factors affecting employability in PWE.

Five hundred and ninety three cases of clinically diagnosed and suspected epilepsy were analysed as regards to the EEG (standard scalp electrode recording) features for confirmation and typing. Fifty-five per cent of all clinically diagnosed adult epileptics were confirmed by the EEG with the initial record, and the EEG confirmatory rate in children was higher at 92%. The frequency of generalised epilepsy as confirmed by the EEG was found to be 86% in adults and 92% in children, reflecting a higher proportion of generalised epilepsy in the population than reported elsewhere. Clinical diagnosis of partial epilepsy was often subsequently shown to be of generalised type on EEG.
Governments in emerging markets face mounting challenges in managing health spending, building capability and capacity, modernizing ageing infrastructure, and investing in skills and resources. One path to overcoming these challenges is to establish new public-private models of health care development and delivery based on United States academic medical centers, whose missions are to advance medical education and clinical delivery. Johns Hopkins Medicine is a participant in the collaboration developing between the Perdana University Hospital and the Perdana University Graduate School of Medicine in Malaysia. These two organizations comprise an academic health science center based on the United States model. The Perdana project provides constructive insights into the opportunities and challenges that governments, universities, and the private sector face when introducing new models of patient care that are integrated with medical education, clinical training, and biomedical research.
AIM: Interactions between different determinants of alpha-thalassemia raises considerable problems, particularly during pregnancies where antenatal diagnosis is necessary. This study aims to determine the different types of deletional alpha-thalassemia and Hemoglobin Constant Spring (HbCS), and their frequency in Malays, Chinese and Indians in Malaysia.
METHODS: DNA from 650 pregnant women from the Antenatal Clinic of the University of Malaya Medical Center in Kuala Lumpur, Malaysia who showed mean cell volume < or =89 fL and/or mean cell hemoglobin < or =28 pg were analyzed for the double alpha-globin gene South-East Asian deletion (--SEA), the -alpha3.7 and -alpha4.2 single alpha-globin gene deletions and HbCS.
RESULTS: One hundred and three (15.8%) of the pregnant women were confirmed as alpha-thalassemia carriers: 25 (3.8%) were alpha-thalassemia-1 carriers with the --SEA/alphaalpha genotype, 64 (9.8%) were heterozygous for the -alpha3.7 rightward deletion (-alpha3.7/alphaalpha), four (0.6%) were heterozygous for the -alpha4.2 leftward deletion (-alpha4.2/alphaalpha), nine (1.4%) were heterozygous for HbCS (alphaCSalpha/alphaalpha) and one (0.2%) was compound heterozygous with the -alpha3.7/alphaCSalpha genotype. The double alpha-globin gene --SEA deletion was significantly higher in the Chinese (15%) compared to the Malays (2.5%) and not detected in the Indians studied. The -alpha3.7 deletion was distributed equally in the three races. HbCS and -alpha4.2 was observed only in the Malays.
CONCLUSION: The data obtained gives a better understanding of the interactions of the different alpha-thalassemia determinants in the different ethnic groups, thus enabling more rapid and specific confirmation of alpha-thalassemia in affected pregnancies where antenatal diagnosis is necessary.

This is a case report of an extremely rare condition of atlanto-axial subluxation secondary to gouty arthritis, which mimicked rheumatoid arthritis at presentation. Gouty arthritis involving the spine is a rare condition. We highlight a case of gouty arthritis involving the atlanto-axial joint resulting in joint instability, subluxation, and neurological deficit. A 66-year-old obese woman who had a polyarticular disease for the previous 3 years presented with neck pain and progressive neurology. A 2-stage procedure was performed: posterior decompression and occipitocervical fusion followed by further anterior trans-oral decompression. However, after an initial neurological improvement, she succumbed to aspirational pneumonia and septicaemia. Atlanto-axial subluxation caused by gouty arthritis can present in the same way as rheumatoid arthritis. Therefore, the possibility of this as a differential diagnosis should be kept in mind.
: We present our initial experience using a simple and relatively cost effective system using existing mobile phone network services and conventional handphones with built in cameras to capture carefully selected images from hard copies of scan images and transferring these images from a hospital without neurosurgical services to a university hospital with tertiary neurosurgical service for consultation and management plan.
