    BACKGROUND: While it is well established that perioperative use of oral nutrition supplement (ONS) improves nutrition status among severely malnourished surgical cancer patients, the evidence requires further substantiation for non-severely malnourished patients with cancer. This protocol paper presents the rationale and design of a randomised controlled trial to evaluate the effectiveness of preoperative as well as an extended 90-day postoperative use of ONS on nutritional and clinical outcomes among patients undergoing elective surgery for breast and colorectal cancer.

    METHODS: Patients with primary breast and colorectal cancer undergoing elective surgery are recruited from two tertiary hospitals. Eligible patients are assigned into one of the three intervention arms: (i) Group SS will receive ONS in addition to their normal diet up to 14 days preoperatively and postoperatively up to discharge; (ii) Group SS-E will receive ONS in addition to their normal diet up to 14 days preoperatively, postoperatively up to discharge and for an extended 90 days after discharge; and (iii) Group DS will receive ONS in addition to their normal diet postoperatively up to discharge from the hospital. The ONS is a standard formula fortified with lactium to aid in sleep for recovery. The primary endpoints include changes in weight, body mass index (BMI), serum albumin and prealbumin levels, while secondary endpoints are body composition (muscle and fat mass), muscle strength (handgrip strength), energy and protein intake, sleep quality, haemoglobin, inflammatory markers (transferrin, high sensitivity C-reactive protein, interleukin-6), stress marker (saliva cortisol), length of hospital stay and postoperative complication rate.

    DISCUSSION: This trial is expected to provide evidence on whether perioperative supplementation in breast and colorectal cancer patients presenting with high BMI and not severely malnourished but undergoing the stress of surgery would be beneficial in terms of nutritional and clinical outcomes.

    Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of uncommon diseases. Given its rarity and multisystem clinical presentation which are usually serious and potentially fatal, prompt recognition and early treatment are of utmost importance. We report a case of AAV that presented with digital infarcts, cutaneous vasculitis, rapidly progressive glomerulonephritis, mononeuritis multiplex, eosinophilia and positive myeloperoxidase (MPO)-ANCA antibody. Apart from renal damage, there was complete recovery in other systems following intravenous cyclophosphamide and high-dose glucocorticoids albeit the response was delayed. This response obviates the need for second-line therapy with newer agent such as rituximab (anti-CD20 monoclonal antibody). We would also like to highlight that this is the first case of AAV that is associated with autoimmune thyroid disease to be reported from Malaysia.

    A six year retrospective study of the demography, clinical and laboratory features of patients with systemic sclerosis (SSc) was carried out in Selayang Hospital. There were 61 cases seen between January 2000 and December 2005. Of these, 55 (90.2%) were females and 6 (9.8%) were males. Twenty-eight (45.9%) were Malays, 24 (39.3%) were Chinese and 9 (14.8%) were Indians. The mean age of onset was 38.8 years. Thirty-nine (64.0%) had limited cutaneous SSc, 21 (34.4%) had diffuse cutaneous SSc and one had localized morphoea. Raynaud's phenomenon was present in 82.6%, telangiectasia in 45.9%, calcinosis in 11.5%, sclerodactyly in 83.6%, digital pitting scars in 42.6%, digital infarcts/ulcers/gangrene in 23.0%, arthralgia/arthritis in 49.2% and gastroesophageal reflux disease (GERD) in 47.5%. Forty-three (70.5%) patients had interstitial lung disease. Seven patients had associated myositis, 7 systemic lupus erythematosus and 2 rheumatoid arthritis. Three had two other connective tissue diseases. Antinuclear antibodies were positive in 83.6% and anti-Scl 70 antibodies in 34.4%. This study demonstrates that limited cutaneous SSc is more common and there is a high incidence of interstitial lung disease in our population.

    A middle aged lady presented with clinical manifestations of primary amyloidosis which included amyloid cardiomyopathy. There was failure to confirm the diagnosis of amyloidosis with biopsies from rectal and tongue tissues. Fat tissue obtained from abdominal subcutaneous fat aspiration eventually demonstrated the presence of amyloid.

    This is the first review on orthognathic surgery in Malaysia. The records of a total of 84 patients seen between 1977 and 1999 in the Department of Oral and Maxillofacial Surgery of the Faculty of Dentistry, University of Malaya were analysed. Skeletal III deformity formed 85% of the sample with a female dominance of 2 to 1. The patients' age ranged from 17 to 36 years, with a mean of 25.3 years. The common surgical techniques used were combined bilateral sagittal split and Le Fort I osteotomy. The predominant ethnic group was Chinese (n = 58, 69%); followed by Malay (n = 14, 17%) and Indian (n = 12, 14%).

    Over a seven-year period, 170 cases of humerus fractures were plated in Hospital Melaka. Of these, 131 cases were successfully traced for this study. Besides looking at fracture epidemiology, its relationship with radial nerve injury was examined. The incidence of post-traumatic wrist drop in closed and compound fractures were 14.9% and 35.3% respectively. In relation to the site of fracture, lower third fracture had the highest incidence of wrist drop (29%). The recovery from post-traumatic wrist drop was 83%. The average duration taken for recovery was 11.8 weeks. The incidence of post-operative wrist drop was high at 17.6% but all recovered during follow-up.

    The neuroleptic malignant syndrome (NMS) is a potentially fatal complication of antipsychotic therapy. A retrospective study of nine patients seen over six years at the University Hospital, Kuala Lumpur (UHKL), is described. The estimated annualised incidence was 1.2 per 1000 in-patients with psychosis. No ethnic difference was detected. Clinical features were similar to experiences elsewhere, with wide variability seen in the severity of illness. The neuroleptic drugs implicated were haloperidol, trifluoperazine, chlorpromazine, fluphenazine and clopenthixol. Treatment consisted of withdrawal of offending drugs and supportive measures. Specific therapy was given to five patients. There was one death. At follow-up no deterioration was detected. A different neuroleptic drug was successfully re-introduced in four patients. In view of the wide usage of major tranquillizers, a high degree of clinical awareness of this serious complication is necessary for early diagnosis to reduce morbidity and mortality.

    A 44 year old lady with primary hypothyroidism presented with massive pericardial effusion without cardiac tamponade. Pericardial tap was done twice and the effusion resolved as the hypothyroid state improved. She remained hypertensive despite the euthyroid state. She was discharged well with L-thyroxine and anti-hypertensive therapy.

    Circadian variations have been observed in the onset of acute coronary syndromes including acute myocardial infarction. We studied 422 acute myocardial infarction patients who presented to the coronary care unit of General Hospital Kuala Lumpur. Of the 318 (75.4%) patients whose data was complete, a circadian rhythm with bimodal peak was demonstrated. The second quarter of the day i.e. 6.00 a.m. to 12 noon was shown to have a significantly increased frequency of onset of acute myocardial infarction (p less than 0.05). Time delay in presenting to the hospital was also determined. This showed that 56.8% of acute myocardial infarction patients presented early, within four hours of the onset of symptoms. By six hours, more than 71% had sought hospital care. This early presentation to the hospital may offer a realistic opportunity for optimal thrombolytic therapy should this treatment modality be offered as routine to infarct patients.

    In a prospective case-control study over a two-year period involving 1006 women, 264 women with acute myocardial infarction (AMI), 305 with non-infarct acute coronary syndromes (CAD) were compared with 437 women with no coronary heart disease (Controls), to determine the relationship between cigarette smoking and other risks factors with coronary heart disease. A history of current cigarette smoking was strongly associated with the risk of coronary events for both AMI And CAD (p less than 0.001). 23.9% of patients with acute coronary syndromes were current smokers, compared with only 12.8% among controls. Overall, women smokers had about a two-fold increase in risk for all coronary events. Younger women smokers (less than 40 years) and those between 61-70 years had particularly higher risks (10.3 and 2.7 times respectively (p less than 0.01, p less than 0.02). A dose-response pattern of increased AMI risks (from 2.0 to 2.9 times) among women smokers was also found, corresponding to the number of cigarettes smoked per day (p less than 0.05). Other significant coronary risk factors established were: postmenopausal status (OR 6.5), diabetes mellitus (OR 5.1), hypertension (OR 1.6), family history of premature coronary heart disease less than 50 years (OR 1.3) and use of oral contraceptive pills (OR 1.4). Our results thus emphasize that cigarette smoking is an important determinant of acute coronary events even among Malaysian women.

    We present a rare case of post-antiretroviral therapy (ART) paradoxically worsening of radiological findings in a patient with advanced HIV-infection on treatment for Rhodococcus pneumonia who was misdiagnosed with pulmonary tuberculosis. Despite clinical improvement, serial chest radiographs showed deteriorations a month after starting ART. This was attributed to Immune Reconstitution Inflammatory Syndrome (IRIS) which spontaneously resolved without any treatment.

    OBJECTIVES: High rates of syphilis have been reported worldwide among men who have sex with men (MSM). This study aims to describe the clinical pattern and treatment response of syphilis among human immunodeficiency virus (HIV)-infected MSM in Malaysia.

    METHODS: This is a retrospective study on all HIV-infected MSM with syphilis between 2011 and 2015. Data was collected from case notes in five centres namely Hospital Kuala Lumpur, Hospital Sultanah Bahiyah, Hospital Umum Sarawak, University of Malaya Medical Centre and Hospital Sungai Buloh.

    RESULTS: A total of 294 HIV seropositive MSM with the median age of 29 years (range 16-66) were confirmed to have syphilis. Nearly half (47.6%) were in the age group of 20-29 years. About a quarter (24.1%) was previously infected with syphilis. Eighty-three patients (28.2%) had other concomitant sexually transmitted infection with genital warts being the most frequently reported (17%). The number of patients with early and late syphilis in our cohort were almost equal. The median pre-treatment non-treponemal antibody titre (VDRL or RPR) for early syphilis (1:64) was significantly higher than for late syphilis (1:8) (p<0.0001). The median CD4 count and the number of patients with CD4 <200/μl in early syphilis were comparable to late syphilis. Nearly four-fifth (78.9%) received benzathine-penicillin only, 5.8% doxycycline, 1.4% Cpenicillin, 1% procaine penicillin, and 12.4% a combination of the above medications. About 44% received treatment and were lost to follow-up. Among those who completed 1 -year follow-up after treatment, 72.3% responded to treatment (serological non-reactive - 18.2%, four-fold drop in titre - 10.9%; serofast - 43.6%), 8.5% failed treatment and 17% had re-infection. Excluding those who were re-infected, lost to follow-up and died, the rates of treatment failure were 12.1% and 8.8% for early and late syphilis respectively (p=0.582).

    CONCLUSION: The most common stage of syphilis among MSM with HIV was latent syphilis. Overall, about 8.5% failed treatment at 1-year follow-up.

    A pregnant woman with antiphospholipid syndrome presented with repeated venous thromboembolism (VTE) in the first and second trimesters of pregnancy despite receiving combination therapy with low-molecular-weight heparin and aspirin. The addition of hydroxychloroquine prevented further VTE recurrence, thus demonstrating its potential antithrombotic effects.

    INTRODUCTION: This study evaluates factors that influence door to operation theatre (OT) time in a tertiary referral centre following activation of trauma team. Specific factors observed in this study were association of the injury severity score (ISS), activation of trauma team and the number of referred specialty to door to operation theatre time.

    METHODS: Retrospective chart review that evaluates all trauma patients which required immediate operative intervention from January 2011 to December 2015. Trauma patients were selected from the resuscitation log book and data were collected by chart review of selected patients.

    RESULTS: Only 5 out of 279 patients (1.8%) achieved optimal door to OT time. (<60 minutes) Mean door to OT time was 299.27 minutes (95% CI: 280.52, 318.52). Trauma team activation has shown significant improvement in door to OT time (p=0.047). Time of multiple team referrals (p=0.023) and time of operative decision (p<0.001) both had significant impact on door to OT time. Other factors included were demographics, ISS score, Glasgow Coma Scale (GCS), mechanism of injury and systolic blood pressure on arrival all which showed no significance.

    CONCLUSION: Trauma team activation in a tertiary centre improved trauma care by reducing door to OT time to less than 60 minutes. Implementation of an effective trauma team activation system in all hospitals throughout Malaysia is recommended.
