    OBJECTIVES: To identify the common bacteria of otorhinolaryngological (ORL) infection in three general hospitals in the state of Sarawak, East Malaysia and to determine the antibiotic sensitivity of the common bacteria to update local antibiotic policy.
    METHODS: All specimens with positive monoclonal culture, received from inpatient and outpatient Otorhinolaryngology Department in the year 2009 and 2010 were included in the study. Patients' demographics, nature of specimens, bacterial isolates and antibiotic sensitivity were analysed by using the Statistical Package for the Social Sciences (SPSS).
    RESULTS: A total 244 positive monoclonal cultures were identified. Staphylococcus species and Gram negative bacilli were the commonest bacteria of ORL infections. Common ORL bacteria remain sensitive to our front line antibiotics. There are a number of multi-drug resistant isolates of MRSA, ESBL Klebsiella pneumoniae and Acinetobacter baumanii in the hospital-acquired infections.
    CONCLUSION: Although resistance to antimicrobial agents is growing worldwide, first line antibiotics still show significant therapeutic advantage in our local setting. The low resistance of bacterial isolates in our community reflects judicious use of antibiotics in our routine clinical practices.

    The Association of Southeast Asian Nations (ASEAN) Mutual Recognition Arrangement (MRA) on medical practitioners' agreement will become a reality in the year 2015. Doctors registered in one ASEAN country will be given reciprocal recognition in another country under this agreement. Rapid and excessive movement of human resources between countries in a short span of time is undesirable and can be destabilizing. The surgical fraternity in the ASEAN countries should plan for a common surgical curriculum, a common examination and an ASEAN Board of Surgery so that standards of future trainees in different countries are comparable. The curriculum should take into consideration the diversity of the countries in socio-economic development. Ideally, it should be based on a public health approach to bring affordable quality surgical care to the masses in an efficient and effective manner.

    Post-transplant lymphoproliferative disorder (PTLD) is a recognized complication exclusive to solid organ transplant recipients and carries a high mortality. We retrospectively reviewed records of all renal transplant recipients under follow up at our institution over the last seven years (2005-2011). We reviewed the patient characteristics, immunosuppression regimen and risk factors for the development of PTLD and its outcomes in our transplant cohort. Four out of 63 patients were diagnosed with PTLD. PTLD was incidentally diagnosed on a transplant biopsy that was performed for an unexplained rise in serum creatinine in three patients. The fourth patient presented with left submandibular lymphadenopathy. Majority presented within 18 months of renal transplantation. After the diagnosis of PTLD on graft biopsy, all patients were fully investigated and two patients had systemic involvement. In the patients with systemic involvement, reduction of immunosuppression and anti B cell therapy with Rituximab was used with good success. The patient with submandibular lymphadenopathy received chemotherapy in addition to reduction of immunosuppression. Three PTLD cases were polyclonal and diagnosed early whereas the fourth case was monoclonal. PTLD can sometimes be incidentally diagnosed on an allograft biopsy performed for rejection. The incidence of PTLD in our centre is higher than reports from other centres but our outcome is good if recognised and treated early.

    Acute coronary syndrome (ACS) patients with positive troponin T (TnT) test are at higher risk for death and myocardial reinfarction. They would significantly benefit from early aggressive pharmacologic and invasive therapy. However, TnT test is not widely available. This retrospective study of 173 patients with ACS showed: that prolonged or repetitive episodes of angina at rest in the previous 24 hours (p = 0.01) and evidence of myocardial ischaemia on ECG (p < 0.001) were associated with positive TnT tests (> or = 0.1 ng/mL). The two variables in combination showed 100% positive predictive value, facilitating early identification and streamlining of therapy.

    The aim of this study was to determine the accuracy of sonographic chorionicity determination in the largest sample of twin pregnancies to date. We retrospectively analyzed 463 twin pregnancies delivered over a 6-year period to determine in each case what the antenatal sonographic prediction of chorionicity was, and then what the subsequent post partum pathological diagnosis of chorionicity was. Out of 436 twin pregnancies, 428 were correctly diagnosed for chorionicity as confirmed by pathology reports. Sonography as a screening tool for monochorionic twin pregnancies has a sensitivity of 100%, a specificity of 97.9% and a predictive value positive of 88.2%. Transvaginal scanning in the first trimester determined twin chorionicity with a sensitivity and a specificity of 100%. This study has confirmed in the largest sample to date that sonographic chorionicity determination is best done in the first trimester using vaginal scans, where it has 100% accuracy.

    A retrospective study was conducted to determine the incidence of nerve injuries in anterior dislocations of the shoulder and to determine if a neurological examination is routinely performed in such cases. One hundred and fifteen shoulder dislocations in 100 patients (74 males, 26 females; mean age 35+/-18 years) were reviewed. Eighty-seven patients were examined for neurological injuries prior to reduction and 8 of these patients (9.2%) were found to have sustained neurological injuries. Following reduction, neurological examination was performed in 85 patients. Three patients who were not examined initially prior to reduction were subsequently found to have nerve injuries after reduction. Seven patients (7%) were not examined for neurological injury both before and after reduction of the dislocation. Eleven patients were found to have sustained nerve injuries in the final analysis. Axillary nerve injuries were the most common, occurring in 8 patients. In conclusion, nerve injuries are common in shoulder dislocations. The importance of performing and documenting the findings of neurological examination anterior shoulder dislocations needs to be reiterated.

    Suboptimal viral suppression and CD4 response to antiretroviral treatment (HAART) is known to cause poor outcomes with the increase cost of treatment. We aimed to assess factors associated with such control among HIV/AIDS patients in Malaysia. Four hundred and six HIV/AIDS patients, using Antiretroviral Therapy (ART) for at least the past three months, treated as outpatients at medication therapy adherence clinics (MTAC) were recruited. CD4 cell counts, viral load readings along with co-variants such as socio-demographic factors, adverse drug reactions, comorbidities, and medication record were obtained. Statistical Package for Social Sciences (SPSS(®) ) version 18 and STATA IC(®) version 12 were used for data analysis. CD4 counts were found highest among those within the age category 41-50 years (390.43 ± 272.28), female (402.64 ± 276.14), other ethnicities (400.20 ± 278.04), and participants with no formal education (414.87 ± 290.90). Patients experiencing adverse effects had a 2.28 (95%CI:1.25-4.18) fold greater risk of poor CD4 control, while patients with comorbidities had 2.46 (95%CI:1.02-5.91) fold greater risk of mild viral suppression. Adverse drug reactions, co-morbidities were found to be significantly associated with poor immunological and virological outcomes in HIV/AIDS patients. However, a comprehensive evaluation is needed to better understand other confounders.

    BACKGROUND: The Cervical Ripening Balloon (CRB) is a novel mechanical method for induction of labour (IOL), reducing the risks of hyperstimulation associated with pharmacological methods. However, there remains a paucity of literature on its application in high risk mothers, who have an elevated risk of uterine rupture, namely those with previous scars and grandmultiparity.

    METHODOLOGY: A retrospective study on IOL using the CRB in women with previous caesarean section or grandmultiparity between January 2014 and March 2015. All cases were identified from the Sarawak General Hospital CRB request registry. Individual admission notes were traced and data extracted using a standardised proforma.

    RESULTS: The overall success rate of vaginal delivery after IOL was 50%, although this increases to about two-thirds when sub analysis was performed in women with previous tested scars and the unscarred, grandmultiparous woman. There was a significant change in Bishop score prior to insertion and after removal of the CRB. The Bishop score increased by a score of 3.2 (95% CI 2.8-3.6), which was statistically significant (p<0.01) and occurred across both subgroups, not limited to the grandmultipara. There were no cases of hyperstimulation but one case of intrapartum fever and scar dehiscence each (1.4%). Notably, there were two cases of change in lie/presentation after CRB insertion.

    CONCLUSION: CRB adds to the obstetricians' armamentarium and appears to provide a reasonable alternative for the IOL in women at high risk of uterine rupture. Rates of hyperstimulation, maternal infection and scar dehiscence are low and hence appeals to the user.

    OBJECTIVES: The levator hiatus is the largest potential hernial portal in the human body. Excessive distensibility is associated with female pelvic organ prolapse (POP). Distension occurs not just laterally but also caudally, resulting in perineal descent and hiatal deformation or 'warping'. The aim of this study was to quantify the warping effect in symptomatic women, to validate the depth of the rendered volume used for the 'simplified method' of measuring hiatal dimensions and to determine predictors for the degree of warping.

    METHODS: This was a retrospective study utilizing records of patients referred to a tertiary urogynecological service between November 2012 and March 2013. Patients underwent a standardized interview, clinical assessment using the POP quantification system of the International Continence Society and four-dimensional translabial ultrasound. The craniocaudal difference in the location of minimal distances in mid-sagittal and coronal planes was determined by offline analysis of ultrasound volumes, and provided a numerical measure of warping. We tested potential predictors, such as demographic factors, signs and symptoms of prolapse, levator avulsion and levator distensibility, for an association with warping.

    RESULTS: Full datasets were available for 190 women. The mean craniocaudal difference in location of minimal distances in mid-sagittal and coronal planes was -1.26 mm (range, -6.7 to 4.6 mm; P

    OBJECTIVE: The natural history of asymptomatic (silent) gallstones has been inadequately studied. Existing information derives from studies based on oral cholecystography or relatively small sample sizes. We planned a retrospective cohort study in subjects with gallstones to determine conversion rates from asymptomatic to symptomatic.
    METHODS: We extracted data from computerised databases of one government hospital and two private clinics in Malaysia. Files were scrutinised to ensure that criteria for asymptomatic gallstones were fulfilled. Patients were called on telephone, further questioned to confirm that the gallstones at detection were truly asymptomatic, and asked about symptoms that were consistent with previously defined criteria for biliary colic. Appropriate ethical clearances were taken.
    RESULTS: 213 (112 males) patients fulfilled the criteria for asymptomatic gallstones and could be contacted. 23 (10.8%) developed pain after an average follow up interval of 4.02 years (range 0.1-11 years). Conversion rates from asymptomatic to symptomatic gallstones were high in the first two years of follow up, averaging 4.03±0.965 per year. Over time the conversion rates slowed, and by year 10 the annual conversion rate averaged only 1.38±0.29. Conversion rates were much higher for females compared to males (F:M hazard ratio 3.23, SE 1.54, p>z 0.014). The lifetime risks for conversion approached 6.15% for males, and 22.1% for females.
    CONCLUSION: In conclusion, asymptomatic gallstones are much more likely to convert to symptomatic in females than in males. Males in whom asymptomatic stones are discovered should be advised conservative treatment. Surgery may be preferable to conservative management if the subject is a young female.

    PURPOSE: Cataract surgery is the most common intraocular surgery performed all over the world and has advanced technically in recent years. As in all surgeries, complications are unavoidable. Herein we report factors associated with complications and visual outcomes of cataract surgery.

    METHODS: This retrospective cohort study included data of 1,632 cataract surgeries performed from 2007 to 2010 which was obtained from the cataract registry of the Malaysian National Eye Database. Demographic features, ocular and systemic comorbidites, grade of surgeon expertise and duration of surgery, type of anesthesia, intraoperative and postoperative complications, and the type of intraocular lens were recorded. Best corrected visual acuities were compared before and after the operation.

    RESULTS: Mean patient age was 66.9 years with equal gender distribution. The majority of subjects had age related cataracts. Phacoemulsification was done faster than other surgeries, especially by specialist surgeons. History of prior ocular surgery and operations performed under general anesthesia were associated with greater complications. Phacoemulsification was associated with less complications and better visual outcomes. The age and etiology of cataract did not affect complications. Malays, absence of ocular comorbidities, left eyes and eyes operated under local anesthesia were more likely to experience more visual improvement. Gender, age, cause of cataract, systemic comorbidities and surgeon expertise as well as intra-and postoperative complications did not affect the visual outcomes.

    CONCLUSION: Phacoemulsification had good visual outcomes in cataract surgery. Duration of surgery, expertise of the surgeon and complications did not affect the visual outcomes.

    Background. Not all yeast alcohol dehydrogenase 2 (ADH2) are repressed by glucose, as reported in Saccharomyces cerevisiae. Pichia stipitis ADH2 is regulated by oxygen instead of glucose, whereas Kluyveromyces marxianus ADH2 is regulated by neither glucose nor ethanol. For this reason, ADH2 regulation of yeasts may be species dependent, leading to a different type of expression and fermentation efficiency. Lachancea fermentati is a highly efficient ethanol producer, fast-growing cells and adapted to fermentation-related stresses such as ethanol and organic acid, but the metabolic information regarding the regulation of glucose and ethanol production is still lacking. Methods. Our investigation started with the stimulation of ADH2 activity from S. cerevisiae and L. fermentati by glucose and ethanol induction in a glucose-repressed medium. The study also embarked on the retrospective analysis of ADH2 genomic and protein level through direct sequencing and sites identification. Based on the sequence generated, we demonstrated ADH2 gene expression highlighting the conserved NAD(P)-binding domain in the context of glucose fermentation and ethanol production. Results. An increase of ADH2 activity was observed in starved L. fermentati (LfeADH2) and S. cerevisiae (SceADH2) in response to 2% (w/v) glucose induction. These suggest that in the presence of glucose, ADH2 activity was activated instead of being repressed. An induction of 0.5% (v/v) ethanol also increased LfeADH2 activity, promoting ethanol resistance, whereas accumulating acetic acid at a later stage of fermentation stimulated ADH2 activity and enhanced glucose consumption rates. The lack in upper stream activating sequence (UAS) and TATA elements hindered the possibility of Adr1 binding to LfeADH2. Transcription factors such as SP1 and RAP1 observed in LfeADH2 sequence have been implicated in the regulation of many genes including ADH2. In glucose fermentation, L. fermentati exhibited a bell-shaped ADH2 expression, showing the highest expression when glucose was depleted and ethanol-acetic acid was increased. Meanwhile, S. cerevisiae showed a constitutive ADH2 expression throughout the fermentation process. Discussion. ADH2 expression in L. fermentati may be subjected to changes in the presence of non-fermentative carbon source. The nucleotide sequence showed that ADH2 transcription could be influenced by other transcription genes of glycolysis oriented due to the lack of specific activation sites for Adr1. Our study suggests that if Adr1 is not capable of promoting LfeADH2 activation, the transcription can be controlled by Rap1 and Sp1 due to their inherent roles. Therefore in future, it is interesting to observe ADH2 gene being highly regulated by these potential transcription factors and functioned as a promoter for yeast under high volume of ethanol and organic acids.

    BACKGROUND: The incidence of out-of-hospital cardiac arrest (OHCA) in women is thought to be lower than that of men, with better outcomes in some Western studies.
    OBJECTIVES: This study aimed to investigate the effect of gender on OHCA outcomes in the Pan-Asian population.
    METHODOLOGY: This was a retrospective, secondary analysis of the Pan Asian Resuscitation Outcomes Study (PAROS) data between 2009 and 2012. We included OHCA cases which were presumed cardiac etiology, aged 18 years and above and resuscitation attempted by emergency medical services (EMS) systems. We used multi-level mixed-effects logistic regression models to account for the clustering effect of individuals within the country. Primary outcome was survival to hospital discharge.
    RESULTS: We included a total of 40,159 OHCA cases, 40% of which were women. We found that women were more likely to be older and have an initial non-shockable arrest rhythm; they were more likely to receive bystander cardio-pulmonary resuscitation (CPR). The univariate analysis showed that women were significantly less likely to have return of spontaneous circulation (ROSC) at scene or in the emergency department (ED), and had lower rates of survival-to-admission and discharge, and poorer overall and cerebral performance outcomes. There was however, no significant gender difference on outcomes after adjustment of other confounders. Women in the reproductive age group (age 18-44 years) were significantly more likely to have ROSC at scene or in the ED, higher rates of survival-to-admission and discharge, and have better overall and cerebral performance outcomes after adjustment for differences in baseline and pre-hospital factors. Menopausal women (age 55 years and above) were less likely to survive to admission after adjusting for other pre-hospital characteristics but not after age adjustment.
    CONCLUSION: Differences in survival outcomes between reproductive and menopausal women highlight a need for further investigations into the plausible social, pathologic or hormonal basis.

    Objective. The aim of this study was to examine the clinical features, treatment and outcome of systemic lupus erythematosus (SLE) patients in our centre who presented with lupus pneumonitis as the initial manifestation.
    Methods. We performed a retrospective review of all patients who presented with lupus pneumonitis during the initial SLE manifestation from March 2006 to March 2015.
    Results. There were a total of five patients in our study who presented with fever and cough as the main clinical features. All patients had pulmonary infiltrates on chest radiographs. High-resolution computed tomography, which was performed in two patients, showed ground glass opacities with patchy consolidations bilaterally. All patients received high-dose steroids, 80% received intravenous cyclophosphamide and 60% received intravenous immunoglobulin. Two patients died from severe lupus pneumonitis within 2 weeks of admission despite treatment with ventilation, steroids, cyclophosphamide and intravenous immunoglobulin.
    Conclusions. Acute lupus pneumonitis is an uncommon presentation of SLE. Mortality in this case series is 40%.

    OBJECTIVE: There is paucity of data for Takayasu arteritis (TAK) among South Asians. We aimed to evaluate the clinical features, angiographic findings, as well as treatment and outcome of TAK among Malaysian multiethnic groups.

    METHODS: This is a retrospective review of 40 patients with TAK seen in major rheumatology centres in Malaysia between April 2006 and September 2013.

    RESULTS: Majority were female patients (92.5%), with a female-to-male ratio of 12:1. Median duration of disease from diagnosis was 66 months (interquartile range, 33-177 months). Fifteen (37.5%) were Malays, 9 (22.5%) each were Indians and indigenous from East Malaysia and 7 (17.5%) were Chinese. Indian and indigenous from East Malaysia were overrepresented in this disease. The mean (SD) age of symptom onset and diagnosis were 25.5 (8.1) and 27.4 (8.4), respectively. The 3 most common clinical presentations at diagnosis were diminished or absent pulse, which occurred in 80% of the patients, followed by blood pressure discrepancy (60%) and arterial bruit (52.5%). There was no difference in clinical presentation among ethnic groups. The subclavian artery was the commonest vessel involved (72.5%), followed by the carotid artery (65%) and renal artery (47.5%). Eight patients had coronary artery involvement, and 2 patients had pulmonary artery involvement. Type I arterial involvement was the commonest (80.0%), followed by type IV (35%), present in isolation or mixed type. Glucocorticoid was the main medical treatment (90.0%). Nineteen patients (47.5%) underwent revascularization procedures. Five patients died during the follow-up period.

    CONCLUSIONS: The Malaysian TAK cohort had similarities with and differences from other published TAK cohort. A nationwide TAK registry is needed to determine the prevalence of the disease among different ethnic groups.

    Age 18 years is considered as the age of majority by most countries. To ascertain the age of interest, both third molar development (TMD) and eruption (TME) staging scores are beneficial without needing multiple imaging modalities. This study aimed to assess the chronological course of TMD and TME in a Malay sub-adult population and evaluate predictions when specific stage(s) of TMD and TME have been attained that are pertinent to the age group of interest (<18 years or ≥18 years). A sample of 714 digital panoramic images for subjects stratified by age between 14.1 and 23.9 years was retrospectively collected. The techniques described by Gleiser and Hunt (modified by Kohler) and Olze were employed to stage TMD and TME, respectively. A binary logistic regression was performed to predict the 18-year threshold with staging score as predictors. Stages 4-6 (TMD) and A-B (TME) for males and stages 4 (TMD) and A (TME) for females were found to discriminate the <18-year group. For both genders, stages 9-10 (TMD) and D (TME) can be used as reference stages to estimate whether a subject is likely to be ≥18 years, with 94.74-100% and 85.88-96.38% correct predictions, respectively. Stages 4 (TMD) and A (TME) can also be used to identify juveniles (<18 years) with a high degree of correct predictions, 100%. The juvenility of an individual is easily anticipated by using the specific staging scores of both third molar variables (TMD and TME) without complex calculations.

    Autoimmune thyroid disease (ATD) has been associated with other systemic autoimmune diseases. To date, there is limited data on thyroid disorders and autoimmune thyroid disease in Malaysia. The frequency of ATD among 189 systemic lupus erythematosus (SLE) patients was 6.3%, with 2.6% in the hyperthyroid group and 3.7% in the hypothyroid group. Hypothyroidism developed at a much younger mean age (24.3 years), suggesting that SLE might be a predisposing factor for the development of Hashimoto's thyroiditis. There was a higher rate of thyroid peroxidase antibody (TPO) positivity compared with anti-thyroglobulin antibody (Tg) in the hyperthyroid subgroup. This study also demonstrated a greater proportion of ATD patients who demonstrated high titres (≥ 1:6400) of TPO compared with high titres of Tg. Although there was an association between ATD and the presence of anti-Ro/SSA and/or anti-La/SSB antibodies, the absence of sicca symptoms and negative Schirmer's tests suggest a lack of association with secondary Sjogren's syndrome. A novel association between ATD and antiphospholipid syndrome (APS) was detected in our cohort. Hence we propose that patients affected by APS be routinely screened for ATD.

    OBJECTIVES: This study explored the demographic characteristics of hepatitis C patients in the Kota Setar (KS) district, Kedah, Malaysia, the prevalence of intravenous drug use (IVDU) as a risk factor among these patients, and the associations between IVDU and demographic characteristics.

    METHODS: Retrospective data pertaining to 713 patients from January 2009 to December 2013 were retrieved from hospital and disease notification records for analysis. The risk factors for hepatitis C virus (HCV) infection were grouped into IVDU and non-IVDU risk factors for analysis using multiple logistic regression.

    RESULTS: Of the hepatitis C patients included in this study, the most common age group was 31 to 40 years (30.2%), and male patients (91.2%) made up the overwhelming majority. Ethnic Malays constituted approximately 80.4% of the patients, and IVDU was the main risk factor (77.8%) for HCV infection. Multiple logistic regression showed that male patients were 59 times more likely to have IVDU as a risk factor for HCV infection. Single patients were 2.5 times more likely to have IVDU as a risk factor. Patients aged ≥71 years were much less likely than patients aged ≤30 years to have IVDU as a risk factor for HCV infection.

    CONCLUSIONS: IVDU was found to be an important risk factor for HCV infection among patients in the KS district. The factors associated with IVDU included age, sex, and marital status. Appropriate preventive measures should be developed to target the groups in which IVDU is most likely to be a risk factor for HCV infection.

    INTRODUCTION: In Malaysia, late stage presentation of breast cancer (stage III or IV) has been a healthcare problem that varies geographically throughout the country. This study aims to understand the factors influencing late stage of breast cancer at presentation among Malaysian women in Segamat Hospital, Johor, which is a district hospital.

    METHODS: A retrospective descriptive study was conducted on secondary data of all newly diagnosed breast cancer women from 1st August 2011 to 28th February 2014. Secondary data includes age, ethnicity, marital status, family history, education level, occupation, presenting symptom, duration of symptom, tumour size, tumour pathology, tumour grading, oestrogen, progesterone and HER-2 receptor status were collected and analysed using SPSS version 20.0.0.

    RESULT: In total, data from 52 women was analysed and two women were excluded for incompleteness as these women defaulted. Late stage at presentation was 59.6% of all new cases (17.3% stage III and 42.3% stage IV). The commonest age group of all women diagnosed with breast cancer was in the 5th decade. Majority of them were Malay, married and housewives with no family history of breast cancer. The statistically significant factors associated with late stage at presentation include Malay ethnicity (p=0.019), presenting symptoms other than breast lump (p=0.047), and duration of breast lump more than 3 months (p=0.009).

    DISCUSSION/CONCLUSION: The study demonstrated presentation at late stage of breast cancer is a major health concern among Malaysian women in district hospital. This may be attributed to different sociocultural beliefs, strong belief in complementary and alternative medicine, lack of awareness, and difficult accessibility to healthcare services.
