    True and pseudoaneurysms of the visceral arteries are uncommon. They represent 0.1-0.2 percent of all vascular aneurysms. Visceral artery aneurysms (VAAs) should be treated due to their propensity to rupture and associated high mortality. We describe a 58-year-old man with pseudoaneurysm of the inferior pancreaticoduodenal artery and who presented with post-motor vehicle accident abdominal pain and a pulsatile epigastic mass. Computed tomography (CT) showed a pseudoaneurysm of the visceral artery, and selective mesenteric angiography showed the aneurysm to be arising from the inferior pancreaticoduodenal artery. The aneurysm was successfully treated with endovascular coil embolisation. CT angiogram at one month post-procedure revealed persistent occlusion of the aneurysm. To the best of our knowledge, this is the first reported pseudoaneurysm of inferior pancreaticoduodenal artery secondary to blunt abdominal trauma from a motor vehicle accident and also the first reported VAA from Malaysia.

    Matrix metalloproteinase 13 (MMP13) plays a central role in the MMP activation cascade that enables degradation of the extracellular matrix and basement membranes, and it is identified as a potential driver in oral carcinogenesis. Therefore, this study aims to determine the copy number, mRNA, and protein expression of MMP13 in oral squamous cell carcinoma (OSCC) and to associate these expressions with clinicopathological parameters. Copy number, mRNA, and protein expression analysis of MMP13 were determined using real-time quantitative PCR and immunohistochemistry methods in OSCC samples. The correlations between MMP13 expressions and clinicopathological parameters were evaluated, and the significance of MMP13 as a prognostic factor was determined. Despite discrepancies between gene amplification and mRNA and protein overexpression rates, OSCC cases showed high amplification of MMP13 and overexpression of MMP13 at both mRNA and protein levels. High level of MMP13 protein expression showed a significant correlation with lymph node metastasis (P = 0.011) and tumor staging (P = 0.002). Multivariate Cox regression model analysis revealed that high level of mRNA and protein expression of MMP13 were significantly associated with poor prognosis (P < 0.050). Taken together, these observations indicate that the MMP13 protein overexpression could be considered as a prognostic marker of OSCC.

    We report a 57-year-old woman with a 20-year history of hepatitis B presenting with progressive proximal lower limb weakness for the previous 1 month. Previous medical history included a pericardial and pleural effusion, of which no cause was found and pulmonary tuberculosis which has been adequately treated. Examination revealed multiple telangiactasia over face and nail beds and bilateral proximal lower limb weakness of power 4/5. Biochemical investigation revealed a raised erythrocyte sedimentation rate of 36 mm/h, elevated creatinine kinase levels (14,363 IU/L) and raised liver enzymes (alanine aminotransferase 445 IU/L, aspartate aminotransferase 606 IU/L) with high hepatitis B virus DNA (1,021,158 copies/mL). Nerve conduction tests and muscle biopsy were consistent with polymyositis. She received entacavir for hepatitis B treatment. Despite treatment with entacavir for 10 weeks, her weakness persisted and prednisolone was added. Upon commencement of prednisolone, her symptoms and biochemical profiles returned to normal.

    : Open cranial vault remodeling techniques require rigid fixation with hardware such as plates and screws; however, complications can occur. The purpose of this study was to assess the surgical outcome after open reconstruction for craniosynostosis with less rigid fixation using nonabsorbable suture.

    METHODS: Retrospective review of patients who underwent open craniofacial reconstruction for craniosynostosis at the Hospital Kuala Lumpur between January 2011 and December 2016 were performed. Demographic data, surgical complications, and postoperative aesthetic outcomes and reoperations were evaluated using Whitaker classification. Statistical analyses were performed using SPSS.

    RESULTS: Thirty-four (n = 34) cases were included in this review consisting of 16 males and 18 females (ratio 1:1.25). Sixteen patients were syndromic with multiple suture synostoses: Apert syndrome (n = 8), Crouzon syndrome (n = 6), and Muenke's syndrome (n = 2). Eighteen patients were nonsyndromic: isolated single-suture craniosynostosis (n = 12) and multiple suture involvement (n = 6). Mean age of presentation was 17.4 months (4-16 months) with mean age of surgery of 23.8 months (6-68 months). Mean length of surgery was 6.1 hours (range 3-10 hours) and mean length of hospital stay was 10 days (mean 7-20 days). Mean duration of follow-up was 2.2 years (6 month-4 years). There were a total of 9 complications postoperatively: massive blood loss (n = 4), seroma (n = 2), exposure keratitis (n = 1), hand extravasation (n = 1), and occipital sore (n = 1). Analysis showed multiple suture craniosynostoses were associated with longer operative times (4.3 hours vs 6.5 hours, P = 0.0082 24 months of age, P = 0.00059). Patients were categorized as 88.2% (n = 30) Whitaker I and II and 11.8% (n = 4) Whitaker III and IV. Reoperation rates were 2.9% (n = 1). Whitaker III and IV class were higher among patients with syndromic synostosis, unicoronal and multiple suture synostoses.

    CONCLUSIONS: Our technique of open cranial reconstruction with nonabsorbable suture nylon 2/0 as sole method of fixation has resulted in good aesthetic outcome with low reoperations and complications rate. Longer follow-up is needed to ascertain our long-term results.

    Many aspects of care such as management of hypercoagulable state in COVID-19 patients, especially those admitted to intensive care units is challenging in the rapidly evolving pandemic of novel coronavirus disease 2019 (COVID-19). We seek to systematically review the available evidence regarding the anticoagulation approach to prevent venous thromboembolism (VTE) among COVID-19 patients admitted to intensive care units. Electronic databases were searched for studies reporting venous thromboembolic events in patients admitted to the intensive care unit receiving any type of anticoagulation (prophylactic or therapeutic). The pooled prevalence (and 95% confidence interval [CI]) of VTE among patients receiving anticoagulant were calculated using the random-effects model. Subgroup pooled analyses were performed with studies reported prophylactic anticoagulation alone and with studies reported mixed prophylactic and therapeutic anticoagulation. We included twelve studies (8 Europe; 2 UK; 1 each from the US and China) in our systematic review and meta-analysis. All studies utilized LMWH or unfractionated heparin as their pharmacologic thromboprophylaxis, either prophylactic doses or therapeutic doses. Seven studies reported on the proportion of patients with the previous history of VTE (range 0-10%). The pooled prevalence of VTE among ICU patients receiving prophylactic or therapeutic anticoagulation across all studies was 31% (95% CI 20-43%). Subgroup pooled analysis limited to studies reported prophylactic anticoagulation alone and mixed (therapeutic and prophylactic anticoagulation) reported pooled prevalences of VTE of 38% (95% CI 10-70%) and 27% (95% CI 17-40%) respectively. With a high prevalence of thromboprophylaxis failure among COVID-19 patients admitted to intensive care units, individualised rather than protocolised VTE thromboprophylaxis would appear prudent at interim.

    Pancreatic pseudocyst is a well recognized complication of acute or chronic pancreatitis. Active treatment (surgical or endoscopic) has been recommended if the pseudocyst persists for more than 6 weeks after the diagnosis. Open trans-abdominal drainage was initially the mainstay treatment for it. However, over the past decade, laparoscopic techniques have been developed to provide patient with minimal access alternative. We report a case of a large symptomatic pseudocyst which developed following attack of severe gallstone pancreatitis. Laparoscopic cholecystectomy and cysto-gastrostomy were done at the same sitting. The operative technique is briefly explained.

    The cytological features of a rare case of undifferentiated (embryonal) sarcoma of the liver are presented. The cytology smears showed singly dispersed polygonal and spindle cells as well as loose clusters of cells held together in myxoid material. Neoplastic cells were generally large with round, oval or lobulated nuclei. The cytoplasm was variable in amount with ill-defined borders. Occasional multinucleated cells were also present. Hyaline globules were present on sections of the cell block. Immunohistochemical studies performed showed positivity for vimentin, cytokeratin and alpha-1-antitrypsin (AAT) in the tumour cells.

    BACKGROUND: Octogenarians and beyond have often been neglected in the populational study of disease despite being at the highest point of non-modifiable disease risk burden and the fastest-growing age group for the past decade. This study examined the characteristics and in-hospital management of octogenarian patients with acute coronary syndrome (ACS) in a multi-ethnic, middle-income country in South East Asia.

    METHOD: This retrospective study utilised the Malaysian National Cardiovascular Disease- ACS (NCVD-ACS) registry. Consecutive patient data of those ≥80 years old admitted with ACS at 24 participating hospitals from 2008 to 2017 (n = 3162) were identified. Demographics, in-hospital intervention, and evidence-based pharmacotherapies over the 10-years were examined and compared across groups of interests using the Chi-square test. Multivariate logistic regression was used to calculate the adjusted odds ratio of receiving individual therapies according to patients' characteristics.

    RESULTS: Octogenarians made up 3.8% of patients with ACS in the NCVD-ACS registry (mean age = 84, SD ± 3.6) from 2008 until 2017. The largest ethnic group was Chinese (44%). Most octogenarians (95%) have multiple cardiovascular risk factors, with hypertension (82%) being the main. Non-ST-elevation myocardial infarction (NSTEMI) predominated (38%, p

    Background Tyrosine kinase inhibitors have been demonstrated to improve the survival of patients with chronic myeloid leukaemia. However, medication adherence is vital for patients on chronic treatment. Objective The objective of the current study was to evaluate response to treatment, adherence by patients to tyrosine kinase inhibitors and factors associated with adherence and response. Setting A haematology clinic in a regional referral hospital in Malaysia. Method Patients aged ≥ 13 years who had been on imatinib or nilotinib for ≥ 12 months were included in this cross-sectional study. An optimal response was defined as the achievement of major molecular response at 12 months of treatment. Patient medication adherence was determined using the average medication possession ratio based on the dispensing records. The patients were considered adherent if the medication possession ratio was > 90%. Multiple logistic regression was performed to evaluate the factors associated with adherence. The association of adherence with molecular response was analysed by univariate logistic regression. Main outcome measure The primary outcome measures were the proportion of patients who achieved optimal response and the medication possession ratio. Results A total of 151 patients were screened, and 71 patients were included. Twenty-eight patients (39%) achieved major molecular response at 12 months of treatment. The median time to achieve this was 15.5 months (an interquartile range of 15). The mean medication possession ratio for imatinib and nilotinib was 0.94 (± 0.14) and 0.96 (± 0.10), respectively, but this difference was without statistical significance (t  =  - 0.517, p  =  0.610). Nausea and vomiting (odds ratio [OR] of 0.25, 95% confidence interval [CI]: 0.07-0.83, p  =  0.023) and disease phase at diagnosis (OR of 0.20, 95% CI 0.04-1.06, p  =  0.059) were associated with patient adherence. An association was not found between patient adherence and molecular response (OR of 1.03, 95% CI 0.35-3.09, p  =  0.956). Conclusion The patients in this study demonstrated a relatively deep molecular response and optimal adherence. Nevertheless, one fourth of them were noncompliant with imatinib. Therefore, active interventions are warranted to prevent treatment-associated adverse events and improve adherence.

    INTRODUCTION: Anemia is one of the most frequent hematological demonstration of malignant diseases, leading to impairment of function in all tissues and organs of cancer patients and associated with serious stress. This major problem may be exacerbated by radiotherapy or chemotherapy. It is characterized by lower hemoglobin (Hb) level or inadequate circulating red blood cells (RBCs). The present study evaluated the effectiveness of treatment guidelines for anemia among solid cancer patients in Penang hospital and to find associations between treatments and anemia onset and severity.

    METHODS: This is a retrospective observational study was conducted on 534 cancer patients with anemia who were admitted to a government hospital on Penang island i.e., Penang General Hospital in the period between 2003 to 2009.

    RESULTS: Effectiveness of standard anemia treatment guidelines was not sufficient because correction of anemia was just temporary.

    CONCLUSION: According to the results, erythropoietin must be used as a cornerstone even for patients who suffer from moderate anemia and blood transfusion should be used just for emergency cases when anemia leads to a critical situation.

    RATIONALE: Epidemiological studies have suggested a beneficial effect of fish oil supplementation in halting the initial progression of Alzheimer's disease. However, it remains unclear whether fish oil affects cognitive function in older people with mild cognitive impairment (MCI).

    OBJECTIVES: This study investigated the effects of fish oil supplementation on cognitive function in elderly person with MCI.

    METHODS: This was a 12-month, randomised, double-blind, placebo-controlled study using fish oil supplementation with concentrated docosahexaenoic acid (DHA). Thirty six low-socioeconomic-status elderly subjects with MCI were randomly assigned to receive either concentrated DHA fish oil (n = 18) or placebo (n = 18) capsules. The changes of memory, psychomotor speed, executive function and attention, and visual-constructive skills were assessed using cognitive tests. Secondary outcomes were safety and tolerability of the DHA concentrate.

    RESULTS: The fish oil group showed significant improvement in short-term and working memory (F = 9.890; ηp (2) = 0.254; p

    Colorectal cancer (CRC) is one of the most common malignancies. In recent decades, early diagnosis and conventional therapies have resulted in a significant reduction in mortality. However, late stage metastatic disease still has very limited effective treatment options. There is a growing interest in using viruses to help target therapies to tumour sites. In recent years the evolution of immunotherapy has emphasised the importance of directing the immune system to eliminate tumour cells; we aim to give a state-of-the-art over-view of the diverse viruses that have been investigated as potential oncolytic agents for the treatment of CRC.

    PURPOSE: The sociodental model integrates clinical assessment, perceived impacts of malocclusion on quality of life, and behavioural propensity when prioritising orthodontic treatment. This study compares the effect of using different instruments to measure impact-related need on the assessment of orthodontic treatment need based on the sociodental framework.

    MATERIALS AND METHODS: In this cross-sectional study, 206 Malaysian adolescents (age: 11-18 years) were screened in orthodontic clinics to identify those with normative need, oral impacts due to malocclusion, and having high and medium-to-high behavioural propensities. The Index of Orthodontic Treatment Need classified normative need. The Psychosocial Impact of Dental Aesthetics (PIDA) questionnaire and the Condition-Specific Child-Oral Impacts on Daily Performances (CS-OIDP) index measured oral impacts. Subjects' behavioural propensities for successful treatment outcome were based on the Basic Periodontal Examination and International Caries Detection and Assessment System. Data were analysed using the McNemar test.

    RESULTS: The response rate was 99.0%. Estimates of normative need (89.7%) were significantly reduced under the sociodental model by 65.7% (p treatment was 24.0% (p treatment when assessed with the sociodental approach were substantially lower than normative clinical assessment and depended highly on the tools selected to assess the patient's impact-related need. Health policy makers should understand the implication of adopting one instrument or the other when estimating orthodontic treatment need.

    The interconnected Ras/ERK and PI3K/AKT pathways play a central role in colorectal tumorigenesis, and they are targets for elucidating mechanisms involved in attempts to induce colon cancer cell death. Both ginger (Zingiber officinale) and honey have been shown to exhibit anti-tumor and anti-inflammation properties against many types of cancer, including colorectal cancer. However, there are currently no reports showing the combined effect of these two dietary compounds in cancer growth inhibition. The aim of this study was to evaluate the synergistic effect of crude ginger extract and Gelam honey in combination as potential cancer chemopreventive agents against the colorectal cancer cell line HT29.

    Magnetic Resonance-guided focused Ultrasound Surgery (MRgFUS) is gaining popularity as an alternative to medical and surgical interventions in the management of symptomatic uterine fibroids. Studies have shown that it is an effective non-invasive treatment with minimal associated risks as compared to myomectomy and hysterectomy. MRgFUS can be offered to a majority of patients suffering from symptomatic uterine fibroids. It has been suggested that the use of broader inclusion criteria as well as the mitigation techniques makes it possible to offer MRgFUS to a much larger subset of patients than previously believed. This paper will describe how MRgFUS treatment for uterine fibroids is performed at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia.

    Chikungunya virus (CHIKV) outbreaks have led to a serious economic burden, as the available treatment strategies can only alleviate disease symptoms, and no effective therapeutics or vaccines are currently available for human use. Here, we report the use of a new cost-effective approach involving production of a recombinant antiviral peptide-fusion protein that is scalable for the treatment of CHIKV infection. A peptide-fusion recombinant protein LATA-PAP1-THAN that was generated by joining Latarcin (LATA) peptide with the N-terminus of the PAP1 antiviral protein, and the Thanatin (THAN) peptide to the C-terminus, was produced in Escherichia coli as inclusion bodies. The antiviral LATA-PAP1-THAN protein showed 89.0% reduction of viral plaque formation compared with PAP1 (46.0%), LATA (67.0%) or THAN (79.3%) peptides alone. The LATA-PAP1-THAN protein reduced the viral RNA load that was 0.89-fold compared with the untreated control cells. We also showed that PAP1 resulted in 0.44-fold reduction, and THAN and LATA resulting in 0.78-fold and 0.73-fold reductions, respectively. The LATA-PAP1-THAN protein inhibited CHIKV replication in the Vero cells at an EC50 of 11.2μg/ml, which is approximately half of the EC50 of PAP1 (23.7μg/ml) and protected the CHIKV-infected mice at the dose of 0.75mg/ml. We concluded that production of antiviral peptide-fusion protein in E. coli as inclusion bodies could accentuate antiviral activities, enhance cellular internalisation, and could reduce product toxicity to host cells and is scalable to epidemic response quantities.

    Management of severe open tibial fracture with neurovascular injury is difficult and controversial. Primary amputation is an acceptable option as salvaging the injured, insensate, and ischaemic limb may result in chronic osteomyelitis and non-functional limb. We report a case of open tibial fracture associated with segmental bone and soft tissue loss, posterior tibial nerve and artery injuries, which was further complicated by chronic osteo-myelitis treated with composite vascularised osteocutaneous fibula and sural nerve graft. Functional outcome of the injured limb at one-year follow-up was satisfactory: the patient was capable of achieving full weightbearing and was able to appreciate crude touch, pain, proprioception, and temperature at the plantar aspect of the foot. There was no pressure sore or ulceration.
