    Better methods are required to identify patients with asymptomatic carotid stenosis (ACS) at risk of future stroke. Two potential markers of high risk are echolucent plaque morphology on carotid ultrasound and embolic signals (ES) in the ipsilateral middle cerebral artery on transcranial Doppler ultrasound (TCD). We explored the predictive value of a score based on these 2 measures in the prospective, observational, international multicenter Asymptomatic Carotid Emboli Study.

    This case series compared clinical variables and various combinations of immunotherapy received with outcomes of patients with severe acute necrotizing encephalopathy (ANE). We performed a retrospective review of clinical variables, immunotherapy received, and outcomes (based on the modified Rankin Scale) in Malaysia between February 2019 and January 2020. Twenty-seven children (12 male), aged 7 months to 14 years (mean 4 years) at diagnosis were included. Of these, 23 had an ANE severity score of 5 to 9 out of 9 (high risk). Eleven patients received tocilizumab (four in combination with methylprednisolone [MTP], seven with MTP + intravenous immunoglobulin [IVIG]) and 16 did not (two received MTP alone, 14 received MTP + IVIG). Nine died. Among the survivors, six had good outcomes (modified Rankin Score 0-2) at 6 months follow-up. All patients who received tocilizumab in combination with MTP + IVIG survived. Twenty children received first immunotherapy within 48 hours of admission. No significant association was found between the timing of first immunotherapy with outcomes. Those with brainstem dysfunction (p = 0.016) were observed to have poorer outcomes. This study showed a trend towards better survival when those with severe ANE were treated with tocilizumab in combination with MTP + IVIG. However, larger studies will be needed to determine the effect of this regime on the long-term outcomes.

    BACKGROUND AND AIMS: Early identification of non-response to steroids is critical in patients with autoimmune hepatitis (AIH) causing acute-on-chronic liver failure (ACLF). We assessed if this non-response can be accurately identified within first few days of treatment.

    METHODS: Patients with AIH-ACLF without baseline infection/hepatic encephalopathy were identified from APASL ACLF research consortium (AARC) database. Diagnosis of AIH-ACLF was based mainly on histology. Those treated with steroids were assessed for non-response (defined as death or liver transplant at 90 days for present study). Laboratory parameters, AARC, and model for end-stage liver disease (MELD) scores were assessed at baseline and day 3 to identify early non-response. Utility of dynamic SURFASA score [- 6.80 + 1.92*(D0-INR) + 1.94*(∆%3-INR) + 1.64*(∆%3-bilirubin)] was also evaluated. The performance of early predictors was compared with changes in MELD score at 2 weeks.

    RESULTS: Fifty-five out of one hundred and sixty-five patients (age-38.2 ± 15.0 years, 67.2% females) with AIH-ACLF [median MELD 24 (IQR: 22-27); median AARC score 7 (6-9)] given oral prednisolone 40 (20-40) mg per day were analyzed. The 90 day transplant-free survival in this cohort was 45.7% with worse outcomes in those with incident infections (56% vs 28.0%, p = 0.03). The AUROC of pre-therapy AARC score [0.842 (95% CI 0.754-0.93)], MELD [0.837 (95% CI 0.733-0.94)] score and SURFASA score [0.795 (95% CI 0.678-0.911)] were as accurate as ∆MELD at 2 weeks [0.770 (95% CI 0.687-0.845), p = 0.526] and better than ∆MELD at 3 days [0.541 (95% CI 0.395, 0.687), p  6, MELD score > 24 with SURFASA score ≥ - 1.2, could identify non-responders at day 3 (concomitant- 75% vs either - 42%, p

    The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. Due to the rapid advancements in the knowledge and available information, a consortium of members from countries across Asia Pacific, "APASL ACLF Research Consortium (AARC)," was formed in 2012. A large cohort of retrospective and prospective data of ACLF patients was collated and followed up in this data base. The current ACLF definition was reassessed based on the new AARC data base. These initiatives were concluded on a 2-day meeting in February 2014 at New Delhi and led to the development of the final AARC consensus. Only those statements which were based on the evidence and were unanimously recommended were accepted. These statements were circulated again to all the experts and subsequently presented at the annual conference of the APASL at Brisbane, on March 14, 2014. The suggestions from the delegates were analyzed by the expert panel, and the modifications in the consensus were made. The final consensus and guidelines document was prepared. After detailed deliberations and data analysis, the original proposed definition was found to withstand the test of time and identify a homogenous group of patients presenting with liver failure. Based on the AARC data, liver failure grading, and its impact on the "Golden therapeutic Window," extra-hepatic organ failure and development of sepsis were analyzed. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals, and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information are presented here.

    BACKGROUND: Metabolic risk factors may impact the severity and outcome of alcoholic liver disease. The present study evaluated this effect in patients with alcohol-associated acute-on-chronic liver failure (ACLF).

    METHODOLOGY: One thousand two hundred and sixteen prospectively enrolled patients with ACLF (males 98%, mean age 42.5 ± 9.4 years, mean CTP, MELD and AARC scores of 12 ± 1.4, 29.7 ± 7 and 9.8 ± 2 respectively) from the Asian Pacific Association for the Study of the Liver (APASL) ACLF Research Consortium (AARC) database were analysed retrospectively. Patients with or without metabolic risk factors were compared for severity (CTP, MELD, AARC scores) and day 30 and 90 mortality. Information on overweight/obesity, type 2 diabetes mellitus (T2DM), hypertension and dyslipidaemia were available in 1028 (85%), 1019 (84%), 1017 (84%) and 965 (79%) patients respectively.

    RESULTS: Overall, 392 (32%) patients died at day 30 and 528 (43%) at day 90. Overweight/obesity, T2DM, hypertension and dyslipidaemia were present in 154 (15%), 142 (14%), 66 (7%) and 141 (15%) patients, respectively, with no risk factors in 809 (67%) patients. Patients with overweight/obesity had higher MELD scores (30.6 ± 7.1 vs 29.2 ± 6.9, P = .007) and those with dyslipidaemia had higher AARC scores (10.4 ± 1.2 vs 9.8 ± 2, P = .014). Overweight/obesity was associated with increased day 30 mortality (HR 1.54, 95% CI 1.06-2.24, P = .023). None of other metabolic risk factors, alone or in combination, had any impact on disease severity or mortality. On multivariate analysis, overweight or obesity was significantly associated with 30-day mortality (aHR 1.91, 95% CI 1.41-2.59, P

    OBJECTIVE: To report the number of participants needed to recruit per baby born to trial staff during AVERT, a large international trial on acute stroke, and to describe trial management consequences.

    DESIGN: Retrospective observational analysis.

    SETTING: 56 acute stroke hospitals in eight countries.

    PARTICIPANTS: 1074 trial physiotherapists, nurses, and other clinicians.

    OUTCOME MEASURES: Number of babies born during trial recruitment per trial participant recruited.

    RESULTS: With 198 site recruitment years and 2104 patients recruited during AVERT, 120 babies were born to trial staff. Births led to an estimated 10% loss in time to achieve recruitment. Parental leave was linked to six trial site closures. The number of participants needed to recruit per baby born was 17.5 (95% confidence interval 14.7 to 21.0); additional trial costs associated with each birth were estimated at 5736 Australian dollars on average.

    CONCLUSION: The staff absences registered in AVERT owing to parental leave led to delayed trial recruitment and increased costs, and should be considered by trial investigators when planning research and estimating budgets. However, the celebration of new life became a highlight of the annual AVERT collaborators' meetings and helped maintain a cohesive collaborative group.

    A retrospective review of medical records was carried out to determine the pattern of drug and chemical poisoning cases admitted to a teaching hospital in Malaysia. Medical records of patients admitted during the period January 1987 to December 1995 were reviewed. They accounted for 0.2% of total admissions during the period. While all ages were represented, there was predominance of children, which showed little change throughout the nine-year period. Of all cases of poisoning, 77.8% were unintentional, 12.6% intentional and 9.6% were undetermined. Kerosene, pesticides and medicinal substances remained the common agents associated with poisoning. A significant number of patients sought treatment elsewhere before being admitted to the hospital. Of those who came directly to the hospital, many were presented late in the course of their poisoning. Only seven patients died and none were children. This study supports the need for greater emphasis on prevention of poisoning in children and among farmers in the state.

    Introduction: Patients receiving continuous ambulatory peritoneal dialysis (CAPD) are commonly associated with peritonitis. However, little is known about the utilization of antibiotics for the treatment of peritonitis in these patients.

    Objectives: This study aimed to evaluate the patterns of intraperitoneal (IP) antibiotic utilization for the treatment of peritonitis in CAPD patients.

    Materials and Methods: This is a retrospective study conducted at a tertiary hospital setting in Malaysia. Medical records of CAPD patients who were diagnosed with peritonitis and registered with National Kidney Registry from 2013 to 2018 were reviewed. Types of antibiotics used and its dose and duration were recorded and reported using the anatomical therapeutic chemical/defined daily dose (ATC/DDD) system.

    Results: A total of 105 peritonitis episodes were recorded from 72 patients. The most common first-line empirical antibiotic combinations used were ceftazidime/cefazolin (40%, n = 42), followed by cefepime/cefazolin (30.5%, n = 32) and ceftazidime/cloxacillin (25.7%, n = 27). The definitive therapy for culture-proven CAPD-related peritonitis (CAPD-P) showed that vancomycin was the most frequently prescribed antibiotic (31.7%, n = 26/82), followed by amikacin (14.6%, n = 12/82), meropenem (11%, n = 9/82) and ampicillin (11%, n = 9/82). Ciprofloxacin was among the least prescribed definitive antibiotics for CAPD-P (2.4%, n = 2/82) but the DDD/100 patient-days estimates showed that it had the highest therapeutic intensity.

    Conclusion: There are various IP antibiotics used for CAPD-P and the most common empirical therapy was the combination of ceftazidime and cefazolin while vancomycin is predominantly used for definitive therapy. Future studies to evaluate the clinical outcomes of the antibiotic use should be conducted to have a better insight on the efficacy of the peritonitis treatment.

    INTRODUCTION: Physiotherapy is an important part of rehabilitation following arthroplasty, but the impact of preoperative physiotherapy on functional outcomes is still being studied. This randomised controlled trial evaluated the effect of preoperative physiotherapy on the short-term functional outcomes of primary total knee arthroplasty (TKA).
    METHODS: 50 patients with primary knee osteoarthritis who underwent unilateral primary TKA were randomised into two groups: the physiotherapy group (n = 24), whose patients performed physical exercises for six weeks immediately prior to surgery, and the nonphysiotherapy group (n = 26). All patients went through a similar physiotherapy regime in the postoperative rehabilitation period. Functional outcome assessment using the algofunctional Knee Injury and Osteoarthritis Outcome Score (KOOS) scale and range of motion (ROM) evaluation was performed preoperatively, and postoperatively at six weeks and three months.
    RESULTS: Both groups showed a significant difference in all algofunctional KOOS subscales (p < 0.001). The mean score difference at six weeks and three months was not significant in the sports and recreational activities subscale for both groups (p > 0.05). Significant differences were observed in the time-versus-treatment analysis between groups for the symptoms (p = 0.003) and activities of daily living (p = 0.025) subscales. No significant difference in ROM was found when comparing preoperative measurements and those at three months following surgery, as well as in time-versus-treatment analysis (p = 0.928).
    CONCLUSION: Six-week preoperative physiotherapy showed no significant impact on short-term functional outcomes (KOOS subscales) and ROM of the knee following primary TKA.

    BACKGROUND: Cataract surgery is associated with a variety of complications, one of which is vitreous loss. Doctors and policymakers should be aware about the precipitating factors, associations, and expected outcomes of vitreous loss. This study was, therefore, undertaken to set guidelines to improve the visual outcomes of patients.

    MATERIALS AND METHODS: A retrospective 8-year analysis was conducted from 2007 to 2014 using the national eye database. Demographic features, ocular comorbidities, grade of surgeon, type of surgery, and the associations with the occurrence of vitreous loss, and the final visual outcomes of these patients were studied.

    RESULTS: Out of 12,992 eyes, only 3.2% had vitreous loss, mostly aged <40 years. Pseudoexfoliation was the only ocular comorbidity causing vitreous loss. Medical Officers and Gazetting Specialists got more vitreous loss compared to specialists. Intracapsular cataract extraction, phaco convert to extracapsular cataract extraction (ECCE), ECCE, and phaco all had a significant vitreous loss. Vitreous loss was the most significant intraoperative complication causing poor vision and resulted in impaired or poor visual outcome.

    CONCLUSION: Vitreous loss occurred in almost all types of cataract surgeries, especially by junior surgeons, among those aged <40 years and significantly caused poor visual outcome compared to other complications. Pseudoexfoliation had higher occurrence of vitreous loss. Vitreous loss patients had impaired/poor visual outcome due to preexisting comorbidity and astigmatism. Patients at risk and junior surgeons should be closely monitored to improve outcomes. Further studies need to be done to see why and when the vitreous loss occurred.

    INTRODUCTION: As in all surgeries, complications during cataract surgery are unavoidable and cause distress to the surgeon and the patient. This study was conducted to know the factors contributing to complications in our settings, to be able to counsel patients about complications and outcomes and to reduce litigations.

    MATERIALS AND METHODS: The secondary data analysis was conducted using the National Eye Database from 2007 to 2014. Demographic features, ocular comorbidities, technique of surgery, grade of surgeons, types of intraoperative complications, and reasons for not obtaining good visual acuity following intraoperative complications were studied. Statistics was done using Statistical Package for Social Sciences version 20.

    RESULTS: Out of 12,992 eyes, 6.1% had intraoperative complications. The highest rate of complications was when more trainees (medical officers [MOs] and gazetting specialists) operated. Posterior capsule rupture (PCR) was the most common complication followed by vitreous loss and zonular dehiscence. Those aged below 40 years had more complications (P < 0.05), and females had more complications. Ethnicity did not affect complications. Pseudoexfoliation was the only comorbidity causing complications (P < 0.05). Phacolytic lenses had 8.118 times the odds of getting intraoperative complications. MOs and gazetting specialists got more complications. Good outcomes were obtained in cases without complications and those operated by specialists. High astigmatism was the main reason for poorer outcomes.

    CONCLUSION: Intraoperative complications were caused mostly by less experienced doctors and had poorer outcomes. Age below 40 years, females, the presence of pseudoexfoliation and phacolytic lenses had more complications. PCR was the most common complication.

    The aim of this study was to determine the predictors of post-traumatic enophthalmos (PE) in relation to the internal orbital changes following pure orbital blowout fractures. The design was a 10-year retrospective cross-sectional study analysing 629 medical records and computed tomography (CT) data of patients with orbital fractures from January 2008 to January 2017. Demographic, etiology, co-morbidity and clinical characteristics were obtained from the medical records. Assessment of the PE, fracture site and size, intraorbital structures and muscle change were performed using the Digital Imaging and Communications in Medicine (DICOM) viewer software, OsiriX v5.8.2. Of the 629 patients with orbital fractures, 87 were pure orbital blowout fractures. Demographic pattern showed that males outnumbered females in the series, with male: female ratio of 5.7:1. The mean age was 37.2 ± 14.7 and the main etiology was motor vehicle accident. Orbital floor fracture was the most common fracture location (67.8%). The involvement of the posterior ledge and inferior orbital fissure showed statistical significant difference with PE (Fisher's exact test, p = 0.03). Binary logistic regression showed that after controlling for age, patients with fracture size of more than 150 mm2 had three times the odds of sustaining a PE, (adjusted odds ratio (AOR) = 3.01 (95% CI 1.17-7.92). Fracture size larger than 150 mm2 was a radiological predictor of PE. Additional research investigating further on the role of concurrent fracture of the posterior ledge and inferior orbital fissure is advocated.

    BACKGROUND: There is high variability among clinicians' decision of appropriate cardiopulmonary resuscitation (CPR) duration before deciding for termination of resuscitation. This study attempted to investigate factors associated with the decision to prolong resuscitation attempts in cardiac arrest patients treated in an emergencydepartment (ED).

    METHODS: A retrospective study that evaluated two years of mortality registry starting in 2015 was conducted in the ED of University Kebangsaan Malaysia Medical Centre (UKMMC), Kuala Lumpur, Malaysia. Adult out-hospital cardiac arrest (OHCA) patients treated in the ED were included. Multivariate logistic regression analysis was utilized for the exploration of factors associated with prolonged CPR attempts (> 30min).

    RESULTS: The median CPR duration was 24min (range 2-68min). Four variables were independently associated with prolonged CPR attempts: younger age (OR, 0.97; 95% CI, 0.95-0.99; p<0.001), pre-existing heart disease (OR, 1.97; 95% CI, 1.07-3.65; p=0.031), occurrence of transient return of spontaneous circulation (ROSC) (OR, 2.38; 95% CI, 1.05-5.36; p=0.037), and access to the ED by nonemergency medical services (EMS) transport (OR, 1.92; 95% CI, 1.09-3.37; p=0.024).

    CONCLUSION: Patient-related and access-related factors were associated with prolonged CPR attempts among OHCA patients resuscitated in the ED.

    Soft tissue tumours are a group of remarkably diverse neoplasms that frequently pose significant diagnostic challenges to general pathologists. This study aimed to compare the agreement of histopathological diagnoses between general pathologists from various referral institutes and the referred soft tissue pathologist in a tertiary centre. The common discrepancies and their causes are also presented here. A retrospective study was conducted on 243 cases of potential soft tissue tumours referred to Hospital Kuala Lumpur, Malaysia over a period of 5 years. Reports by the referring pathologists and the soft tissue pathologist were compared based on tumour classification and tumour behaviour. Overall, there was moderate agreement in soft tissue tumour diagnoses in both tumour classification (weighted κ = 0.423) and tumour behavior (weighted κ = 0.548). The highest agreement of tumour classification was seen in the adipocytic tumours (21/28 cases), Ewing sarcoma (5/7 cases) and smooth-muscle tumours (3/5 cases). The highest rates of discrepancies were the so-called fibrohistiocytic tumours (7/11 cases), vascular tumours (9/15 cases) and undifferentiated/ unclassified sarcomas (19/32 cases). Full agreement for tumour behaviour was seen in 178 cases and there were 21 cases of zero agreement. Liposarcoma, alveolar soft part sarcoma and benign fibrous histiocytoma were the most frequent benign/malignant diagnostic discrepancies. The most common causes of discrepancy were wrong morphological interpretation followed by insufficient immunohistochemical stains performed. In conclusion, review of diagnosis by a pathologist specialized in soft tissue improves the quality of diagnosis in these heterogenous and rare tumours. A good panel of immunohistochemical stains with additional molecular study is crucial in the general hospital laboratories practice.

    A retrospective study was carried out to determine the distribution of intraocular pressure in normal patients who came for vision problems at the Optometry Clinic, Universiti Kebangsaan Malaysia (UKM) Kuala Lumpur Campus, and to determine the differences in intraocular pressure with respect to age, gender and race. The cohort consisted of 148 subjects divided into five groups with age ranged from 10 to 59 years. The inclusion criteria were, subjects had no sistemic or ocular disease, subjects were not taking any medication, visual acuity was 6/6 or better, refractive errors < ±6.00D, astigmatism < 2.00D, anisometropia <2.00D, and mean intraocular pressure measured using the X-PERT tonometer and taken between 9 am to 2 pm. Statistical analysis (ANOVA) showed the mean intraocular pressure without consideration for age, race or gender was 12.6 mmHg (SD ±2.5). There was no significant differences in intraocular pressure between right and left eyes, between different age groups and between different genders. However, the intraocular pressuse for the Chinese was found to be significantly higher than the Malays. It was found that the intraocular pressure of patients who came for vision problems at the Optometry Clinic UKM follows a normal distribution and there was no significant diference found between right and left eyes, between different age groups and genders. Race seemed to contribute to the differences in intraocular pressure. Keywords: Age; clinic population; genders; pressure; intraocular pressure; race

    BACKGROUND: Increasing incidence of dengue cases in Malaysia over the last few years has been paralleled by increased deaths. Mortality prediction models will therefore be useful in clinical management. The aim of this study is to identify factors at diagnosis of severe dengue that predicts mortality and assess predictive models based on these identified factors.

    METHOD: This is a retrospective cohort study of confirmed severe dengue patients that were admitted in 2014 to Hospital Kuala Lumpur. Data on baseline characteristics, clinical parameters, and laboratory findings at diagnosis of severe dengue were collected. The outcome of interest is death among patients diagnosed with severe dengue.

    RESULTS: There were 199 patients with severe dengue included in the study. Multivariate analysis found lethargy, OR 3.84 (95% CI 1.23-12.03); bleeding, OR 8.88 (95% CI 2.91-27.15); pulse rate, OR 1.04 (95% CI 1.01-1.07); serum bicarbonate, OR 0.79 (95% CI 0.70-0.89) and serum lactate OR 1.27 (95% CI 1.09-1.47), to be statistically significant predictors of death. The regression equation to our model with the highest AUROC, 83.5 (95% CI 72.4-94.6), is: Log odds of death amongst severe dengue cases = - 1.021 - 0.220(Serum bicarbonate) + 0.001(ALT) + 0.067(Age) - 0.190(Gender).

    CONCLUSION: This study showed that a large proportion of severe dengue occurred early, whilst patients were still febrile. The best prediction model to predict death at recognition of severe dengue is a model that incorporates serum bicarbonate and ALT levels.

    The Corona pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) calls on the Saudi government to take action to control the infection. The government closed borders, prohibited travel, limited outdoor movements, and told primary and secondary care facilities to reduce all regular non-urgent health services. It is not known whether these measures have impacted the prevalence of parasitic intestinal infections. This study has therefore been carried out to investigate this issue. Dataset of 217 stool samples submitted to the King Faisal Medical Complex (KFMC) Microbiology Laboratory in Taif, Saudi Arabia for parasitological examination during the pandemic (January-June 2020) and 649 samples submitted during the corresponding months of the previous year (January-June 2019) were extracted and analyzed. Overall, 24.1% (209/866) of samples were parasitespositives; 26.6% (173/649) before and 16.5% (36/217) during the pandemic, with 79% reduction. There was a significant difference in gender-parasitism between the two periods where the majority of parasitism were for males (p<0.001). Infections were frequent in patients aged 5- 14 years both before (84/649; 12.9%) and during (12/217; 5.5%) the pandemic, with significant difference observed between the two cohorts (p<0.002). Moreover, the majority of infected patients were non-Saudi (67.9%; 142/209), with a significant difference in nationality reported, (p=0.024). Protozoa were identified in 21.8% (189) of all samples investigated, of which, Blastocystis hominis, Entamoeba coli, Giardia lamblia, Entamoeba histolytica/dispar and Cryptosporidium species were identified in 6.1% (53), 5.4% (47), 5.0% (44), 2.8% (25), and 2.3% (20), respectively. Helminths were diagnosed in 2.3% (20/866) of samples. Eggs of hookworm, Ascaris, Taenia spp, and Hymenolepis nana were detected in 0.9% (8), 0.5% (5), 0.3% (3) and 0.4% (4), respectively. In parallel with our research hypothesis, a substantial decrease in the burden of intestinal parasitic infections was recorded with the lock-down measures taken during the Corona pandemic.
