    The clinicopathological conference, popularly known as CPC primarily relies on case method of teaching medicine. It is a teaching tool that illustrates the logical, measured consideration of a differential diagnosis used to evaluate patients. The process involves case presentation, diagnostic data, discussion of differential diagnosis, logically narrowing the list to few selected probable diagnoses and eventually reaching a final diagnosis and its brief discussion. The idea was first practiced in Boston, back in 1900 by a Harvard internist, Dr. Richard C. Cabot who practiced this as an informal discussion session in his private office. Dr. Cabot incepted this from a resident, who in turn had received the idea from a roommate, primarily a law student.

    Familial defective apolipoprotein B-100 (FDB) is an autosomal dominant genetic disorder associated with hypercholesterolaemia and premature coronary heart disease. FDB is caused by mutations in and around the codon 3500 of the apolipoprotein B (apo B) gene. Apo B R3500Q mutation is the first apo B mutation known to be associated with FDB and it is the most frequently reported apo B mutation in several different populations. The objective of the present study was to determine the association of apo B R3500Q mutation with elevated plasma cholesterol concentration in Kelantanese population in which both hypercholesterolaemia and coronary heart disease are common. Sixty-two Malay subjects with hyperlipidaemia, attending the lipid clinic at Hospital Universiti Sains Malaysia, Kelantan, were selected for this study. The DNA samples were analysed for the presence of apo B R3500Q mutation by polymerase chain reaction-based restriction fragment analysis method using mutagenic primers. This mutation was not detected in the subjects selected for this study. Apo B R3500Q mutation does not appear to be a common cause of hypercholesterolaemia in Kelantanese Malays.

    Neoplastic transformation appears to be a multi-step process in which the normal controls of cell proliferation and cell-cell interaction are lost, thus transforming normal cells into cancer. The tumorigenic process involves the interplay between oncogenes and tumour suppressor genes. In this study, we have selected the ras family, c-myc and epidermal growth factor receptor (EGFR) genes to detect whether their abnormalities are associated with the expression and progression of glioma cases in Malay patients. We have used the polymerase chain reaction-single stranded conformation polymorphism followed by direct sequencing for the study. For the ras gene family, we screened the point mutations in codons 12 and 61 of the H-, K-, and N-ras gene; for EGFR and c-myc, we analyzed only the exon 1 in glioma samples. In mutational screening analyses of the ras family, c-myc and EGFR gene, there was no mobility shift observed in any tumour analyzed. All patterns of single stranded conformation polymorphism (SSCP) band observed in tumour samples were normal compared to those in normal samples. The DNA sequencing results in all high-grade tumours showed that all base sequences were normal. All 48 patients survived after five years of treatment. In simple logistic regression analysis, variables which were found to be significant were hemiplegia (p=0.047) and response radiotherapy (p=0.003). Hemiplegics were 25 times more likely to have high pathological grade compared to those without. Patients with vascular involvement were 5.5 times more likely to have higher pathological grade. However, these findings were not significant in multivariate analysis. Patients who had radiotherapy were nearly 14 times more likely to have higher pathological grade. Multivariate analysis revealed that patients with hemiplegia were more likely to have higher pathological grade (p= 0.008). Those with higher pathological grading were 80 times more likely to have radiotherapy (p=0.004).

    Absorbed dose to water was measured with ionisation chambers NE 2561 (#267), NE 2581 (#334), NE 2571 (#1028), using the IAEA standard water phantom. The ionisation chamber was inserted in the water phantom at a reference depth dependent on the type of the radiation quality used. Three radiation qualities were used namely 1.25 MeV gamma ray, 6 MV x-rays and 10 MV x-rays. The values of the absorbed dose to water were determined by the N(K)- and N(X)- based methods, i.e with the use of IAEA, HPA, NACP, AAPM, NCRP and ICRU protocols. The aim of this study was to make an intercomparison of the results, by taking the IAEA protocol as a standard. The largest deviation contributed by any of these protocols was recorded for each quality. It was found that AAPM, NCRP and ICRU protocols contributed 0.94% for 1.25 MeV gamma ray, NACP contributed 2.12% for the 6 MV x-rays, and NACP contributed 2.35% for 10 MV x-rays. Since the acceptable limit of deviation set by the IAEA for this absorbed dose work is ± 3%, it is clear that the overall deviations obtained were all satisfactory.

    BACKGROUND: Chronic hyperglycaemia of diabetes causes long-term damage and impaired function of multiple organs. However, the pathological changes in the liver following long-term diabetes remain unclear. This study aimed to determine the pathological complications of long-term diabetes in the rat liver.

    METHODS: Intraperitoneal injection of streptozotocin (STZ) was used to induce diabetes in rats at a single dose (60 mg/kg body weight [BW]). Rats were euthanised at 1 month (DM1 group), 2 months (DM2 group) and 4 months (DM4 group) following diabetes induction with six rats in each group. Immunohistochemistry was performed against SOD1, CD68, p53 and p16 antibodies. Messenger RNA (mRNA) expressions of SOD1, SOD2, GPx, CD68, p53, p21 and caspase-3 genes were measured by reverse transcription-polymerase chain reaction.

    RESULTS: Hepatic p53 mRNA expression was significantly higher in DM1, DM2 and DM4 groups compared to the control group. The p21 and caspase-3 mRNA expressions were significantly upregulated in the DM2 and DM4 groups. The p16-positive cells were obviously increased, particularly in the DM4 group. Bivariate correlation analysis showed mRNA expressions of p21 and caspase-3 genes were positively correlated with the p53 gene.

    CONCLUSION: Diabetic rats exhibited increased apoptosis and senescence in the liver following a longer period of hyperglycaemia.

    Background: Computed tomography (CT) attenuation (Hounsfield unit [HU]) value of lumbar vertebra may provide an alternative method in the detection of osteoporosis during CT scans.

    Methods: A cross-sectional study on 50 patients of age 50 and above with contrast-enhanced CT (CECT) and dual-energy X-ray absorptiometry (DXA) was conducted from November 2018 to November 2019. Single region of interest (ROI) was placed at the anterior trabecular part of L1 vertebra on CECT to obtain HU value. Correlation of CT HU value of L1 vertebra and DXA T-score, interrater reliability agreement between HU value of L1 vertebra and T-score in determining groups of with and without osteoporosis, ROC curve analysis for diagnostic accuracy and cut-off value of CT for detection of osteoporosis were identified.

    Results: Significant correlation between HU value of L1 vertebra and L1 T-score (r = 0.683)/lowest skeletal T-score (r = 0.703) (P < 0.001). Substantial agreement between HU value of L1 vertebra and DXA in determining the groups with and without osteoporosis (k = 0.8; P < 0.001). The area under the receiver operating characteristic (AUROC) curve was 0.93 (95% CI: 0.86, 1.00) using HU value (P < 0.001). Cut-off value for osteoporosis was 149 HU.

    Conclusion: HU value of lumbar vertebra is an effective alternative for the detection of osteoporosis with high diagnostic accuracy in hospitals without DXA facility.

    BACKGROUND: Statins are a class of potent drugs that can be used to reduce cholesterol, especially low-density lipoprotein cholesterol (LDL-C). However, their effectiveness is limited if adherence to treatment is poor. The objectives of the study are to estimate the proportion of diabetic patient who has achieved LDL-C goal and to determine the association of LDL-C achievement with socio demographic factors and statin therapy adherence.

    METHODS: This is a cross-sectional study involving 234 patients with type 2 diabetes mellitus (T2DM) and dyslipidaemia attending an outpatient clinic in a hospital in Kelantan. Interviews and self-administered questionnaires were used to determine their sociodemographic and clinical characteristics. Adherence to therapy was assessed using the Medication Compliance Questionnaire (MCQ). The associations between the achievement of LDL targets and sociodemographic/clinical factors, including adherence, were analysed with simple logistic regression.

    RESULTS: About 37.6% of patients achieved their LDL-C target. The percentage of patients who adhered to statin use was 98.3%, and 20.5% of these patients reported full adherence. There was no significant association between achievement of LDL-C targets with adherence or any other sociodemographic factors, such as age, gender and educational or economic status (all P-value < 0.05).

    CONCLUSION: Despite a high level of adherence, the majority of patients failed to achieve LDL-C targets. More concerted efforts are needed to improve this.

    Inflammation of the gallbladder without evidence of calculi is known as acute acalculous cholecystitis (AAC). AAC is frequently associated with a poor prognosis and a high mortality rate. Thus, early diagnosis and prompt surgical intervention has been recommended to improve the outcome of AAC. Herein, I present a case report of AAC complicating laparoscopic appendicectomy. Unlike previous studies that have reported the need for urgent intervention in patients with AAC, in this study, our patient responded to conservative management. Therefore, the management of AAC after laparoscopic appendicectomy should be individualised.

    A 43-year old lady presented with progressive loss of vision in both eyes followed by rapid deterioration of consciousness within the next few days. This was preceded by a viral infection one week before her presentation. At presentation she had evidence of meningism and signs of bilateral upper motor neuron lesions and was managed initially as acute meningoencephalitis with antibiotics. The brain CT was within normal limits but subsequent MRI of the brain revealed multiple foci of hyperintense lesions on T2-weighted and FLAIR images. The cerebrospinal fluid examination revealed lymphocytosis, and normal protein and glucose levels. Cultures of the CSF were negative. She was managed as acute disseminated encephalomyelitis (ADEM) with high-dose of intravenous methlyprednisolone one gram/day for three consecutive days followed by oral prednisolone 60 mg/day. Despite the management she lapsed into coma and succumbed to her illness nine days after admission.

    Acute pancreatitis is considered to be an extremely rare extrahepatic manifestation of acute viral hepatitis E. The incidence is reported to be around 5%-6% in the available case series. It has usually been reported in non-fulminant cases of acute viral hepatitis E in the second or third week of illness, with a favourable outcome. Here, we report the case of a young male subject with acute viral hepatitis E presenting as acute pancreatitis at its onset and exhibiting a prolonged recovery phase. To the authors' knowledge, such a presentation of acute viral hepatitis E as acute pancreatitis at its inception has been only sparsely reported in the available literature.

    We present a young adult female with symptoms of acute tonsillitis and tender cervical lymphadenopathy. Despite a full course of oral antibiotics, she had persistent left lower cervical lymphadenopathy measuring 2.0 x 1.5 cm at 2 weeks post-treatment. Rigid and flexible scope examinations did not reveal any abnormalities in the nasopharynx, oropharynx or hypopharynx. Tuberculosis tests were negative and blood index results were normal. Fine needle aspiration cytology revealed a non-specific granulomatous inflammatory process. Excisional lymph node biopsy was performed, and the patient was diagnosed as having Kikuchi's Disease (KD). We would like to highlight the diagnostic challenges in detecting this condition and the importance of differentiating KD from tuberculosis and malignant lymphoma, the latter of which requires aggressive treatment.

    Acute lower gastrointestinal haemorrhage secondary to small bowel ascariasis is extremely rare. A high level of suspicion should be maintained when dealing with acute gastrointestinal haemorrhage in migrants and travellers. Small bowel examination is warranted when carefully repeated upper and lower endoscopies have failed to elicit the source of bleeding. Appropriate test selection is determined by the availability of local expertise. We present a case of acute lower gastrointestinal haemorrhage secondary to jejunal ascariasis and a literature search on lower gastrointestinal haemorrhage associated with jejunal infestation with Ascaris.

    BACKGROUND: Acute meningoencephalitis is an important cause of morbidity and mortality around the globe. The objective of this study was to examine the distribution of acute meningoencephalitis and its aetiological agents among children admitted to a tertiary hospital in southern Bangladesh.

    METHODS: This prospective study was carried out in Khulna Medical College Hospital from 2007 to 2009. All of the admitted children between 1 month and 12 years of age were enrolled over a 2-year period if they met the inclusion criteria of having an acute onset of fever (≤ 14 days) and any of the following 3 signs: neck stiffness, convulsion, or altered mental status. Cerebrospinal fluid (CSF) was collected within hours and sent to the laboratory for cytological and biochemical analyses. CSF was examined by Gram staining and a latex agglutination test to detect common bacteria. Serum and CSF were also tested for Japanese encephalitis virus antibodies.

    RESULTS: A total of 140 children were included in the study, which accounted for 2.5% of admissions between 2007 and 2009. The number of acute meningoencephalitis cases was relatively higher (37.9%) during the monsoon season. The CSF report revealed a pyogenic form in 24 (18.5%) and a viral form in 13 (10.0%) cases. Altered mental status was significantly less frequent (P < 0.001) in cases of pyogenic meningoencephalitis (62.5%) than in cases of non-pyogenic meningoencephalitis (93.4%). Bacterial causes were identified in 11 (8.5%) children; the causative agents included Streptococcus pneumoniae (n = 8), Neisseria meningitides (n = 2), and Haemophilus influenzae (n = 1). Three (2.3%) patients were positive for Japanese encephalitis virus.

    CONCLUSION: S. pneumoniae was the most common bacteria causing acute meningoencephalitis among the study subjects, and Japanese encephalitis virus was present in few patients.

    Background: Many questionnaires have been developed to measure dental anxiety and fear. Among them is the Index of Dental Anxiety and Fear Scale (IDAF-4C+), which consists of a dental anxiety and fear module (IDAF-4C), a phobia module (IDAF-P) and a stimulus module (IDAF-S). The objective of this research was to report the adaptation and validation of the IDAF-4C+ for Malaysian secondary school children.

    Methods: This was a cross-sectional validation study. The original English version of the IDAF-4C+ was translated into Malay, back-translated, and then sent for content validation via an expert validation and face validation by the target student population. Three hundred and seventy questionnaires were then distributed among 16-year-old school children. Confirmatory factor analysis (CFA) was conducted for the IDAF-4C module using a bootstrapped maximum likelihood estimator. Spearman's rank correlation was used to assess the relationship between the IDAF-S and IDAF-4C modules. Intraclass correlation (ICC) was used to determine the stability of the IDAF-S and IDAF-4C modules, while kappa values were used for the IDAF-P module.

    Results: The response rate was 86.5% for CFA and 76.9% for stability. CFA showed the existence of only one factor with a reliability estimate of 0.921, obtained via Raykov's procedure. All items in the IDAF-S module were significantly correlated with the IDAF-4C module (P < 0.001). The IDAF-S and IDAF-4C modules were stable, as determined via a two-way mixed model with absolute agreement, a single measure and a Case 3 ICC (A, 1). The IDAF-P module showed satisfactory stability, as assessed via kappa values.

    Conclusion: The Malay version of the IDAF-4C+ is valid and reliable in measuring dental anxiety and fear among Malaysian secondary school children.
