    BACKGROUND: Patients with severe psoriasis, namely those requiring phototherapy or systemic treatment, have an increased risk of death. The aim of this study was to determine the prevalence, aetiology and risk factors for mortality among adult patients aged 18 years and above with psoriasis in Malaysia.

    METHODS: This was a retrospective study involving adult patients notified by dermatologists to the Malaysian Psoriasis Registry between July 2007 and December 2013. Data were cross-checked against the National Death Registry. Patients certified dead were identified and the cause of death was analysed. Multivariate analysis using multiple logistic regression were conducted on potential factors associated with higher risk of mortality.

    RESULTS: A total of 419 deaths were identified among the 9775 patients notified. There were four significant risk factors for higher mortality: age>40 years (age 41-60 years old, Odds Ratio (OR) 2.70, 95%CI 1.75, 4.18; age>60 years OR 7.46, 95%CI 4.62, 12.02), male gender (OR 1.72, 95%CI 1.33,2.22), severe psoriasis with body surface area (BSA) >10% (OR 1.52, 95%CI 1.19, 1.96) and presence of at least one cardiovascular co-morbidity (OR 1.67, 95% CI 1.30, 2.14). Among the 301 patients with verifiable causes of death, the leading causes were infection (33.9%), cardiovascular disease (33.6%) and malignancy (15.9%).

    CONCLUSION: Infection was the leading cause of death among psoriasis patients in Malaysia. Although cardiovascular diseases are well-known to cause significant morbidity and mortality among psoriasis patients, the role of infections and malignancy should not be overlooked.

    The incidence of premature multi-vessel coronary artery disease (CAD) is on the rise in Malaysia. The pathogenesis of coronary atherosclerosis is multi-factorial with dyslipidaemia being one such risk factor. Elevated total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglycerides (TG) levels are primarily responsible. We analysed the fasting pre-operative lipid profiles of coronary artery bypass graft (CABG) patients with symptomatic severe premature CAD. A majority of patients had an elevated LDL cholesterol level despite being on a statin. Similarly, no patient with an elevated TG level was prescribed a fibrate. Pre-operative control of known dyslipidaemia was suboptimal in young adults with angiographially proven severe symptomatic CAD. This is either due to subtherapeutic dose prescribing or failure to commence appropriate anti-lipid drugs. Collectively, general practitioners, cardiologists and cardiac surgeons must be more diligent in monitoring lipid profiles in such patients and be more meticulous in prescribing therapeutic doses to achieve target control.

    ABSTRACT: Oral and maxillofacial fractures are the most common injuries among multiple trauma. About 5% to 10% of trauma patients having facial fractures. The objectives of this case study are to focus the most common mid-face fractures types' and to determine the relationship of the midface fracture in maxillofacial trauma among the patient who attended the outpatient clinic in a Hospital Universiti Sains Malaysia. In this research paper, an advanced statistical tool was chosen through the multilayer perceptron neural network methodology (MLPNN). Multilayer perceptron neural network methodology was applied to determine the most associated predictor important toward maxillary bone injury. Through the predictor important classification analysis, the relationship of each bone will be determined, and sorting according to their contribution. After sorting the most associated predictor important toward maxillary bone injury, the validation process will be applied through the value of training, testing, and validation. The input variables of MLPNN were zygomatic complex fracture, orbital wall fracture, nasal bone fracture, frontal bone fracture, and zygomatic arch fracture. The performance of MLPNN having high accuracy with 82.2%. As a conclusion, the zygomatic complex fracture is the most common fracture trauma among the patient, having the most important association toward maxillary bone fracture. This finding has the highest potential for further statistical modeling for education purposes and the decision-maker among the surgeon.

    Catheter-related bloodstream infection (CRBSI) is an important healthcare-associated infection caused by various nosocomial pathogens. Candida parapsilosis has emerged as a crucial causative agent for the CRBSI in the last two decades. Many factors have been associated with the development of CRBSI including, demography, pre-maturity, comorbidities (diabetes mellitus, hypertension, heart diseases, neuropathy, respiratory diseases, renal dysfunction, hematological and solid organ malignancies, and intestinal dysfunction), intensive care unit (ICU) admission, mechanical ventilation (MV), total parenteral nutrition (TPN), prior antibiotic and/or antifungal therapy, neutropenia, prior surgery, immunosuppressant, and type, site, number, and duration of catheters. This study aims to determine C. parapsilosis CRBSI risk factors. A retrospective study has been performed in an 853-bedded tertiary-care hospital in north-eastern Malaysia. All inpatients with C. parapsilosis positive blood cultures from January 2006 to December 2018 were included, and their medical records were reviewed using a standardized checklist. Out of 208 candidemia episodes, 177 had at least one catheter during admission, and 31 cases had not been catheterized and were excluded. Among the 177 cases, 30 CRBSI cases were compared to 147 non-CRBSI cases [81 bloodstream infections (BSIs), 66 catheter colonizers]. The significance of different risk factors was calculated using multivariate analysis. Multivariate analysis of potential risk factors shows that ICU admission was significantly associated with non-CRBSI as compared to CRBSI [OR, 0.242; 95% CI (0.080-0.734); p = 0.012], and TPN was significantly positively associated with CRBSI than non-CRBSI [OR, 3.079; 95%CI (1.125-8.429); p = 0.029], while other risk factors were not associated significantly. Patients admitted in ICU were less likely to develop C. parapsilosis CRBSI while patients receiving TPN were more likely to have C. parapsilosis CRBSI when compared to the non-CRBSI group.

    PURPOSE: Extravasation with intravenous chemotherapy is a common complication of chemotherapy which carries the risk of devastating complications. This study aims to determine the rate of extravasation with intravenous chemotherapy in a major hospital where chemotherapy is delivered in various departments other than the oncology department.

    PATIENTS AND METHODS: All patients who underwent intravenous chemotherapy in the oncology department and surgical wards in Penang General hospital from 1st February 2008 till 31st June 2008 were recruited retrospectively for this study to look at the rate of extravasation.

    RESULTS: A total of 602 patients underwent intravenous chemotherapy during this period. Fifty patients received chemotherapy in the general surgical ward while another 552 patients received chemotherapy in the oncology department. There were 5 cases of extravasation giving an overall extravasation rate of 0.8% (5/602). however, 4 of these cases occurred in the general surgical ward giving it a rate of 8% (4/50).

    CONCLUSION: The rate of extravasation in our hospital was 0.8%. however, this rate can be significantly increased if it is not done under a specialized unit delivering intravenous chemotherapy on a regular basis. Preventive steps including a standard chemotherapy delivery protocol, staff and patient education must be put in place in all units delivering intravenous chemotherapy.

    While it is not difficult to recognise the classical clinical features of congenital syphilis in most cases, some of them may present with unusual manifestations which can defy early diagnosis. We report our experience with 13 cases of early congenital syphilis over a period of 10 years from 1980 to 1989. Twelve of the thirteen patients were less than 3 months at presentation. There were two infants born prematurely and six of the babies were born with a low birthweight (less than 2.5 kg). All but four patients survived following treatment. Skin lesions either in the form of typical vesiculobullous eruption over the palms and soles or a maculopapular skin rash over the body were the most common presentation and was seen in 10 patients. Splenomegaly with or without hepatomegaly was the most consistent physical sign. Radiological changes in the form of periostitis and/or metaphysitis were seen in all cases where an X-ray of the long bones was performed. An elevated serum immunoglobulin M, though non-specific for the disease, was found to be a useful screening test for recent infection.

    Bone lengthening with distraction osteogenesis involves prolonged application of an external fixator frame. Qualitative and quantitative evaluation of callus has been described using various imaging modalities but there is no simple reliable and readily available method. This study aims to investigate the use of a densitometer to analyze plain radiographic images and correlate them with the rate of new bone formation as represented by the bone healing index. A total of 34 bone lengthening procedures in 29 patients were retrospectively reviewed. We used an X-Rite 301 densitometer to measure densities of new callus on plain radiographs taken at 4 and 8 weeks after surgery. Patients aged below 16y had significantly lower BHIs indicating faster bone healing and shorter duration of treatment. The ratio of radiographic densities between centre and edge of the new bone measured from plain radiographs taken at 8 weeks correlated positively with the eventual BHI of the patient. This method provides a simple and easy way to predict the rate of bone healing at an early stage of treatment and may also allow remedial action to be taken for those with poor progress in bone formation.

    The purpose of this study was to assess the tissue
    response of Type 2 diabetic subjects towards non surgical
    periodontal therapy as compared with matched, nondiabetic
    subjects. This was a retrospective, comparative
    study using periodontal case notes of 40 subjects attending
    undergraduates’ periodontal clinics (20 diabetics, 20 nondiabetics),
    who were selected based on the inclusion
    and exclusion criteria. Response towards non surgical
    periodontal therapy was assessed through three clinical
    periodontal parameters, namely plaque score, gingivitis
    score and number of periodontal pocket ≥5mm at the
    baseline and after initial non surgical periodontal therapy.
    Data obtained was then analyzed by SPSS Version 12.
    Both diabetic and non-diabetic subjects showed significant
    improvements (p-value = 0.021; 0.000; 0.001 and 0.010;
    0.014; 0.001) in all three parameters after the therapy.
    However, when comparison was made between the two
    groups, there was no significant difference (p-value = 0.913;
    0.892 and 0.903) in any of the parameters. Periodontal
    conditions improved clinically in both diabetic and nondiabetic
    subjects after non-surgical periodontal therapy.
    Therefore, both groups responded similarly towards the
    therapy and thus it can be postulated that well-controlled
    diabetic status does not have a significant effect on the
    outcome of periodontal therapy.

    The objective of this study was to compare in-patient drug use patterns, costs, and outcomes associated with risperidone or olanzapine in a naturalistic clinical setting. Retrospective chart reviews of 92 patients with psychotic disorders were conducted at the University of Malaya Medical Centre (UMMC). Data was collected from patients who were hospitalized and for whom risperidone or olanzapine was the drug of first choice for long-term pharmacologic treatment. Proportion of patients for whom efficacy of the studied treatment could be established (as rated by the treating physician) was higher, but not significantly, with risperidone compared to olanzapine (p = 0.46). The average dose of the studied medication was 2.9 ± 1.0 mg/day for risperidone and 9.7 ± 2.4 mg/day for olanzapine. The total cost was significantly higher (p

    A surgeon’s experience plays an important role in breast conserving surgery (BCS). The common conception is that, the more junior is the operating surgeon, the surgical margin will be wider or closer to the tumour edge. Thus the aim of this study is to look into the adequacy of surgical margin performed by different level of surgeons’ experience in patients whom underwent wide local excision (WLE) and hook-wire localization (HWL) in our surgical unit. The surgical experience of the operating surgeon and their surgical margins will be analyzed. This is a retrospective study from January 2000 to December 2012. Eighty-eight patients with early breast cancer underwent WLE and HWL by 3 different groups of surgeons (breast surgeons, junior surgeons and surgical registrars) were included. The surgical margins were analyzed for involved-margin, closed-margin or excessed-margin.The incidence of involved-margin, closed-margin and excessed-margin is the lowest among breast surgeons compared to other groups. However, the results were not statistically significant. The incidence of involved surgical margin is significantly higher within junior surgeons for HWL compared to the breast surgeons. The incidence of involved, closed or excessed surgical margin were lowest when performed by breast surgeon but not significantly different between the three groups. However, for HWL the breast surgeons significantly better compared to the other groups.

    Interlocked intramedullary nailing is accepted as the gold standard for femoral shaft fractures. However for Winquist type I and II femoral fractures at the isthmus region, unlocked intramedullary nailing (Küntscher nailing) is still a good option. We performed a retrospective study on 86 patients with a total of 88 femoral shaft fractures around the isthmus that presented at our institution between 1 January 1988 and 31 August 2003. All patients (84.1% Winquist type I and 15.9% Winquist Type II fractures) were treated with unlocked intramedullary nail. The average time to union was 16 weeks with 97.7% rate of union. There were two cases (2.3%) of infection and non-union each. Overall results were comparable to standard interlocking intramedullary nailing. We conclude that unlocked intramedullary nailing is a good treatment option for Winquist Type I and II femoral fracture around the isthmus with its good union rate and minimal complications.

    The purpose of this study is to retrospectively report the results of scoliosis patients who underwent chiropractic therapy and to evaluate their outcome by looking at the potential to alter the natural progression of scoliosis after therapy.
    Methods: Retrospective data collection was conducted at a private chiropractic centre in Kuala Lumpur. The data was collected from patients between the ages of 16 to 19 years old. A total of eight patients with 14 scoliotic curvatures (six thoracic, six lumbar and two thoracolumbar), who met the inclusion criteria, were selected as subjects for this study. All subjects received the same chiropractic therapy program. The outcome of the therapy was assessed by measuring the Cobb’s angle on the erect spine as captured on an x-ray. The Cobb’s angle was measured at the first presentation (to establish a baseline) after 6 and 24 months of therapy.
    Results: The mean baseline Cobb’s angle for thoracic, lumbar and thoracolumbar scoliosis were 30.70 ± 19.40, 31.70 ± 12.30 and 25.00 ± 18.40 respectively. After 24 months of chiropractic therapy, there was no discernible effect on the magnitude of the Cobb’s angles on the subjects overall.
    Conclusion: Our study showed no significant reduction in spine curvature in patients with scoliosis using chiropractic therapy after 24 months.
