    All cycles of IVF with pituitary down-regulation (n = 57) done at the Damansara Fertility Centre in the year 2000 were studied. All the 57 patients had controlled ovarian hyperstimulation, either using Metrodin HP (n = 27) or Gonal-F (n = 30). Of these, 53 patients reached oocyte pick-up, 26 patients in Metrodin HP group and 27 patients in Gonal-F group. Gonal-F resulted in a higher clinical pregnancy rate of 66.6% compared to Metrodin HP 38.5% (p < 0.05). The live birth rate tends to be higher in Gonal-F group (40.7%) compared to Metrodin HP (30.8%), (p > 0.05).

    Diabetic nephropathy (DN) has become the most common cause of end-stage renal failure. Early referral and specific nephrology treatment could delay the disease progression and should reduce the treatment cost, mortality and morbidity rate in these patients. This is a single-center, retrospective review of all DN patients referred to the nephrology clinic in Hospital Sultan Ahmad Shah, Temerloh, from 2000 to 2009, to study and define the clinical characteristics of DN patients at the time of the referral to the nephrology clinic. A total of 75 patient case records were reviewed. Forty-three (57.3%) of them were males, with a median age of 64.3 ± 8.5 years at the time of referral. Only 14.7% of them had blood pressure lower than 125/75 mmHg. Co-morbid and disease-related complications were also commonly diagnosed and 28.4% (n = 21) had ischemic heart disease, 23% (n = 17) had diabetic retinopathy and 20.3% (n = 15) had diabetic neuropathy. The mean serum creatinine at the time of referral was 339.8 ± 2.3 μmol/L, gylcated hemoglobin A 1c (HbA1C) was 8.1 ± 2.0 %, serum fasting glucose was 9.6 ± 4.7 mmol/L, serum cholesterol was 5.4 ± 1.2 mmol/L and hemoglobin level was 10.6 ± 2.9 g/dL. Although female patients were less frequently seen in the early stages of chronic kidney disease (CKD), they comprised at least 72.7% of CKD stage 5 (male:female; 6:16, P <0.05). Twenty-nine percent (n=22) of them were referred at CKD stage 5, 48% (n=36) were at CKD stage 4, 17.3% (n=13) were at CKD stage 3, 4% (n=3) were at CKD stage 2 and 1.3% (n=1) was at CKD stage 1. Advanced CKD patients were frequently prescribed with more antihypertensives. CKD stage 5 patients were prescribed with two-and-half types of antihypertensive as compared to two types of anti-hypertensive in CKD stage 2 and stage 3. Furthermore, ACE-inhibitors (ACE-I) were less frequently prescribed to them. Only 22.7% (n=5) of CKD stage 5 patients received ACE-I and 30% (n=11) in CKD stage 4 patients as compared to 53.4% (n=7) in CKD patients stage 3. This review shows that DN patients were referred late to the nephrologists and the overall disease management was suboptimal. Antihypertensive requirement was also increased and ACEIs were less frequently prescribed in the advanced diabetic nephropathy patients.

    This is a 10-year retrospective review of mucocutaneous infection by human herpesvirus 1 (HHV1) and human herpesvirus 2 (HHV2) carried out by the virus diagnostic unit of University Malaya Medical Centre (UMMC). A total of 504 specimens from UMMC and a private clinic in the same city (KLSC) were tested; 198 samples from patients with oral lesions and 306 from patients with genital lesions. HHV1 was found to be responsible for 98.4% of oral lesions whereas HHV2 was the cause of 83.6% of all genital lesions. Detailed analysis showed no statistical difference by age group, race or gender among the patients with oral and genital lesions. Two laboratory methods were used in this study. Of the total 504 specimens tested, 18.0% specimens were positive by direct immunofluorescence (IF), 55.0% by virus isolation and 56.5% when both methods were used in combination. Although IF can provide a more rapid diagnosis, it is, however, less sensitive and can be attributed partly to inadequate collection of specimens.

    Background Antibiotic de-escalation is an important strategy to conserve the effectiveness of broad-spectrum antibiotics. However, the outcome of this strategy for the treatment of ventilator-associated pneumonia (VAP) has not been widely studied in developing countries. Objectives To evaluate the outcome on intensive care unit (ICU) mortality, 28 days mortality, and length of ICU stay among VAP patients who receive de-escalation therapy. Setting This study was conducted in an ICU of a Malaysian public hospital. Method The electronic medical records of patients who developed VAP in the ICU were retrieved and relevant data was collected. Records of antibiotic prescriptions were also reviewed to collect the details of changes to antibiotic therapy (de-escalation). Main outcome measure Impact of antibiotic de-escalation on mortality. Results The mean age of the 108 patients was 46.2 ± 18.2 years; the majority being males (80%). The antibiotic de-escalation rate was about 30%. Out of this, 84% involved a change from broad to narrow-spectrum antibiotics and the remaining, withdrawal of one or more antibiotics. ICU mortality was 23% while 28 days mortality was 37%. There was no statistically significant difference in mortality rate, survival probability and the mean length of ICU stay between the de-escalation and the non-de-escalation group. However, patients with Simplified Acute Physiology Score II of ≥50 were significantly associated with ICU mortality and 28 days mortality. Conclusions In VAP patients, antibiotic de-escalation provides an opportunity to promote the judicious use of antibiotics without affecting the clinical outcomes.

    A retrospective six-month study of serum calcium and albumin in patients treated at the Kuala Lumpur Hospital was carried out. There were 19,291 subjects, of which the prevalences of hypocalcemia (corrected serum calcium of < or = 2.1 mmol/l) and hypercalcemia (corrected serum calcium of > 2.7 mmol/l) were 18.0% (3460 subjects) and 2.4% (468 subjects) respectively. Persistent hypocalcemia (a minimum of first two consecutive corrected serum calcium of < or = 2.1 mmol/l) was found in 408/19,291 subjects 2.1%). Serum calcium values of < 2.00 mmol/l were found in 98.5% of this group. Persistent hypercalcemia (a minimum of first two consecutive corrected serum calcium of > 2.7 mmol/l) was found in 108/19,291 subjects (0.5%) and 52/108 subjects (48.1%) had serum calcium values of > or = 3.0 mmol/l. 2902/3460 subjects (83.8%) and 313/468 subjects (66.9%) the hypocalcemia and hypercalcemia groups respectively failed to be retested (singletons). In the hypocalcemia group, 1115/2902 (38.4%) showed corrected serum calcium values of < 2.00 mmol/l), whilst 100/313 subjects (31.9%) of the hypercalcemia group had corrected serum calcium values of > or = 3.00 mmol/l. There were no significant differences between the mean corrected serum calcium between 3 age groups of the test population, namely in childhood ( < or = 65 years).

    Background: Atrial fibrillation (AF) is common after cardiac surgery and has been associated with poor outcome and increased resource utilization. The main objective of this study is to determine the incidence of POAF in Malaysia and identify the predictors of developing POAF. The secondary outcome of this study would be to investigate the difference in mortality and morbidity rates and the duration of intensive care unit (ICU), high dependency unit (HDU) and hospital stay between the two. Methods: This is a retrospective single-center, cross sectional study conducted at the National Heart Institute, Malaysia. Medical records of 637 who underwent coronary artery bypass grafting (CABG) surgery in 2015 were accrued. Pre-operative, operative and post-operative information were subsequently collected on a pre-formulated data collection sheet. Data were then analyzed using IBM SPSS v23. Results: The incidence of POAF in our study stands at 28.7% with a mean onset of 45±33 hours post operatively. Variables with independent association with POAF include advancing age, Indian population, history of chronic kidney disease, left ventricular ejection fraction and beta-blocker treatment. The mortality rate is significantly higher statistically ( p < 0.05), and similarly the incidence of stroke. The incidence of other post-operative complications was also significantly higher statistically. The duration of ICU, HDU and hospital stays were statistically longer ( p < 0.001) with higher rates of ICU readmissions and reintubations seen. Conclusion: We conclude that the incidence of POAF in Malaysia is comparable to the figures in Western countries, making POAF one of the most commonly encountered condition after CABG with similar higher rates of mortality, poor outcomes and longer duration of stay, and therefore increased cost of care. Strategies to reduce the incidence of AF after cardiac surgery should favorably affect surgical outcomes and reduce utilization of resources and thus lower cost of care.

    A review of malaria cases over a five year period from 1984-1988 at the University Hospital, Kuala Lumpur, Malaysia is presented. A total of 64 cases were recorded; 50% of which were due to Plasmodium falciparum, 40.6% were due to Plasmodium vivax, 6.2% due to Plasmodium malariae and 3.1% due to a mixed infection of Plasmodium falciparum and Plasmodium vivax. The breakdown of species type compared similarly with other studies conducted in the region. Of this total, sixteen cases were imported from Pakistan, India, Thailand, Indonesia, Sri Lanka, Vietnam, Madagascar and Mali. The presenting symptoms and the clinical findings were typical of a malaria infection. The main problem in the future will be the increase in imported cases of malaria.

    A retrospective analysis of 182 HIV positive Malaysians was done in two centers, the University Hospital Kuala Lumpur (UHKL) and the General Hospital Kuala Lumpur (GHKL) from March 1997 to February 1998. Demographic and clinical data were analyzed. The analysis showed that 130 out of 182 patients had mucocutaneous disorders (71.4%). In the study there were 125 males (96.2%) and 5 females (3.8%). The majority of the patients were in the age group from 20 to 50 years. The patients who presented with mucocutaneous disease also had low CD4+ T lymphocyte counts, and most of them had AIDS defining illnesses. The number of cases with generalized hyperpigmentation was very high (35.7%), followed by papular eruptions (29.1%) and xerosis (27.5%). Seborrheic dermatitis was seen in 19.2% of the cases and psoriasis in 7.7%. The most common infections were oral candida 35.7%, tinea corporis and onychomycosis 9.9%, and herpes infection 4.3%. However, mucocutaneous manifestations of Kaposi's sarcoma were rare. The results suggested that mucocutaneous findings are useful clinical predictors of HIV infection or a sign of the presence of advanced HIV infection.

    JE is neither classified as an entity in the Malaysian Medical records system nor is it a notifiable disease but is grouped under the broad umbrella of viral encephalitis. There is no centralised program by the Ministry of Health specially for JE surveillance and control. JE is endemic, occurs sporadically throughout the country all year round. Asymptomatic inapparent infections have been found to be more frequent than acute clinical encephalitis cases, judging from results of previous serosurveys (Pond et al., 1954). JE vaccination has never been tried in Malaysia. In a relative sense, JEV infection unlike dengue virus infection, does not appear to be much of a problem in Malaysia. Perhaps, the laboratory confirmed cases represent only a small proportion of the total hospitalised cases that actually occurred. The reasons may be that these cases could not be confirmed by laboratory tests due to improper timing or failure to obtain the second serum specimen, or failure to perform lumbar puncture on patient's refusal. Attempts to improve the case detection rate of JE in Malaysia should be made namely, by increasing clinical index of suspicion, instituting better specimen collection procedures and by adopting rapid diagnostic tests.

    In a retrospective study, 455 people were found to have been admitted to the Surgical Unit of the Taiping District Hospital, suspected of acute appendicitis in the study period from 1 July to 31 December 1990. However, only 147 (32.3%) were clinically confirmed to have appendicitis and underwent appendicectomy. Out of these, 120 (81.6%) cases were subjected to detailed analysis. The study showed that the commonest age group affected was the 10 to 20 year old. Males were slightly more often affected but there seemed to be an equal distribution among the major races. The diagnostic accuracy, that is the operated cases that were actually acute appendicitis, was 92.5%. The perforation rate was 31.5%. Fifty-five percent of patients developed some post-operative complications, of which the commonest was fever.

    A total of 39 titles related to rheumatic fever or rheumatic heart disease in Malaysia were found with online literature search dating back to their inceptions and through 2014. Additional publications from conference journals were included. Nine papers were selected based on clinical relevance and future research implications. There were no population-based studies on the incidence or prevalence of ARF or RHD. In the 1980s, the incidence of admission due to ARF ranged from 2 to 21.1 per 100 000 paediatric admission per year. The burden of disease was significant in the adult population; 74.5% of patients with RHD were female, of which 77.1% were in the reproductive age group of 15-45 years old. Rheumatic mitral valve disease constituted almost half (46.7%) of all mitral valve repairs, ranging from 44.8 - 55.8 patients per year from 1997 - 2003. From 2010-2012, mitral valve interventions increased to 184 per year, of which 85.7% were mitral valve repair. In children with ARF, 25.4% - 41.7% had past history of rheumatic fever or RHD. In patients with rheumatic mitral valve disease undergoing surgical or medical interventions, only 6% reported history of ARF, none had history of GABHS pharyngitis or antibiotic prophylaxis. Only 44.7% of patients with RHD on follow-up were on intramuscular benzathine penicillin prophylaxis. Overall, there is scarcity of publications on ARF and RHD in Malaysia. Priority areas for research include determination of the incidence and prevalence of ARF and RHD, identification of high-risk populations, evaluation on the implementation and adherence of secondary preventive measures, identification of subclinical RHD especially amongst the high-risk population, and a surveillance system to monitor and evaluate preventive measures, disease progression and outcomes.

    A literature search of articles as detailed in the paper Bibliography of clinical research in Malaysia: methods and brief results, using the MESH terms Obesity; Obesity, Abdominal; and Overweight; covering the years 2000 till 2015 was undertaken and 265 articles were identified. Serial population studies showed that the prevalence of obesity increased rapidly in Malaysia in the last decade of the twentieth century. This follows the rising availability of food per capita which had been begun two to three decades previously. Almost every birth cohort, even up to those in their seventh decade increased in prevalence of overweight and obesity between 1996 and 2006. However, the rise in prevalence in obesity appears to have plateaued after the first decade of the twentieth century. Women are more obese than men and Malays and Indians are more obese than Chinese. The Orang Asli (Aborigines) are the least obese ethnic group in Malaysia but that may change with socioeconomic development. Neither living in rural areas nor having low income protects against obesity. On the contrary, a tertiary education and an income over RM4,000/month is associated with less obesity. Malaysians are generally not physically active enough, in the modes of transportation they use and how they use their leisure time. Other criteria and measures of obesity have been investigated, such as the relevance of abdominal obesity, and the Asian criteria or Body Mass Index (BMI) cut-offs value of 23.0 kg/m2 for overweight and 27.0 kg/m2 for obesity, with the view that the risk of diabetes and other chronic diseases start to increase at lower values in Asians compared to Europeans. Nevertheless the standard World Health Organization (WHO) guidelines for obesity are still most widely used and hence is the best common reference. Guidelines for the management of obesity have been published and projects to combat obesity are being run. However, more effort needs to be invested. Studies on intervention programmes showed that weight loss is not easy to achieve nor maintain. Laboratory research worldwide has uncovered several genetic and biochemical markers associated with obesity. Similar studies in Malaysia have found some biomarkers with an association to obesity in the local population but none of great significance.

    This is a retrospective review of 110 patients admitted to the Burns Units between October 1999 and November 2001. The aim was to determine the burns pattern of patients admitted to hospital UKM. There was an increasing trend for patients admitted. Female to male ratio was 1:2. Children consisted 34% of the total admission. Children had significant higher number of scald burns as compare to adult (p < 0.01). Domestic burns were consist of 75% overall admission. Mean percentage of TBSA (total body surface area) burns was 19%. Thirty percent of patients sustained more than 20% of TBSA. Sixty percent of patients had scald burns. Ninety percents of patients with second degree burns that were treated with biologic membrane dressing or split skin graft. Mean duration of hospital stay was 10 days. Over 70% of patients were discharged within 15 days. Overall mortality rate was 6.3%. The patients who died had significantly larger area of burns of more than 20% TBSA (p < 0.05) and a higher incidence of inhalation injury (p < 0.02). Hence, this study suggests a need for better preventive measures by the authority to prevent burns related accident and the expansion of the service provided by the Burns Unit.

    Dengue is the most common and widespread arthropod borne arboviral infection in the world today. It is estimated that there are at least 100 million cases of dengue fever (DF) annually and 500,000 cases of dengue hemorrhagic fever (DHF) which require hospitalization. In Malaysia, it has become a major public health problem. Malaysia recorded 19,544 dengue cases in 1997, the highest recorded since the disease was made notifiable in the country. Of 19,544 cases, 806 were DHF with 50 deaths. The objectives of this analysis were to describe the incidence of dengue fever and dengue hemorrhagic fever in Kota Bharu, Kelantan, Malaysia for the years 1998-2003 and to explore the characteristics of dengue fever and dengue hemorrhagic fever in Kota Bharu, Kelantan, Malaysia for years 1998-2003. A total of 4,716 dengue cases were notified involving 4,476 (94.9%) DF and 240 (5.1%) DHF cases, which increased though the years. The highest incidence was in January (701 or 14.9%), while the lowest was in May (188 or 4.0%). Forty percent of cases (n=1,890) were in the 15-29 year old group. The Majority were Malays (4,062 or 86.1%) and 2,602 or 55.2% were male. A total of 4,477 cases (95%) were local cases and 4,289 or 91% came from the urban area. For priority areas, 3,772 (80%) were from priority 1. More than half the cases had positive serology results. All symptoms occurred in more than 96% of cases and fever was the commonest (99.7%). The mean values for age, temperature, systolic and diastolic blood pressure (BP) were 27.8 +/- 15.4 years, 37.9 +/- 0.90 degrees C, 115 +/- 15.2 mmHg and 73 +/- 11.1 mmHg, respectively. The mean value for the time interval between the onset of symptoms and diagnosis, onset of symptoms and notification and time of diagnosis to notification were 5.1 +/- 2.3, 5.9 +/- 2.5 and 0.8 +/- 1.1 days, respectively. There were associations between the types of dengue and classification, area and priority area. Among the symptoms, the association was only seen in joint pain. The mean significant differences between DF and DHF were found in age and systolic blood pressure. The incidence of dengue in Kota Bharu is comparable to that in Malaysia. The increase in the number of cases needs to be addressed promptly with effective surveillance, prevention and control programs.

    INTRODUCTION: The purpose of this study was to analyse the clinical characteristics of patients with idiopathic inflammatory myopathy (IIM) in Hospital Sultanah Nurzahirah (HSNZ), Terengganu, Malaysia. It also aimed to describe the disease manifestations in association with malignancy and other CTD.

    METHODS: This was a retrospective descriptive study involving all IIM patients who were managed by the Rheumatology Unit HSNZ from January 2010 to December 2019.

    RESULTS: In this review we described 15 cases wherein malignancy was detected in 4 patients after the diagnosis of IIM was made and 4 patients with overlap syndrome. One third of patients with malignancy and overlap syndrome had poor treatment response and succumbed to complications of the disease. Almost all of patients received corticosteroid as the first line therapy and nearly two thirds of them responded well to either corticosteroid alone or with combination therapy.

    CONCLUSION: Although this study did not represent the whole population in Malaysia, it does provide a better understanding of the disease manifestation, treatment and disease complications in our cohort of patients.
