    Haematological cellular structures may be elucidated using automated full blood count (FBC) analysers such as Unicel DxH 800 via cell population data (CPD) analysis. The CPD values are generated by calculating volume, conductivity, and five types of scatter angles of individual cells which would form clusters or populations. This study considered 126 CPD parameter values of 1077 healthy Malaysian adults to develop reference intervals for each CPD parameter. The utility of the CPD reference interval established may range from understanding the normal haematological cellular structures to analysis of distinct cellular features related to the development of haematological disorders and malignancies.

    Haemolytic disease of the foetus and newborn (HDFN) is caused by maternal red blood cells (RBC) alloimmunisation resulted from incompatibility of maternal and foetal RBCs. However, only a few HDFN attributed to anti-M were reported, varying from asymptomatic to severe anaemia with hydrops foetalis and even intrauterine death. A case of severe HDFN due to anti-M alloantibody from an alloimmunized grandmultiparous Malay woman with recurrent pregnancy loss is reported here. The newborn was delivered with severe and prolonged anaemia which required frequent RBC transfusions, intensive phototherapy and intravenous immunoglobulin administration. Although anti-M is rarely known to cause severe HDFN, a careful serological work-up and close assessment of foetal well-being is important, similar to the management of RhD HDFN. Alloimmunisation with anti-M type can lead to severe HDFN and even foetal loss.

    We prospectively studied the type, frequency and outcome of infections in 513 patients with 762 consecutive episodes of febrile neutropenia (FN) over a five-year period between 1995 and 1999 in a single paediatric oncology unit. The findings were then compared with a similar study carried out in our unit between 1990 and 1994. The types of bacterial isolates and sensitivity patterns were also studied to identify trends and to gauge the suitability of antibiotics chosen for empirical therapy. Bacteraemia was documented in 35.4% of FN episodes, although 70% of patients did not have an obvious site of sepsis. The majority of isolates (61.9%) were gram-negative bacteria, a consistent finding throughout the study period. Resistance to ceftazidime, amikacin and imipenem among gram-negative bacteria was 26.3%, 21.2% and 0.7%, respectively. Methicillin resistance among gram-positive bacteria was 26.3%, while no vancomycin-resistant bacteria were encountered. There were 36 sepsis-related deaths. Factors associated with a fatal outome were prolonged capillary refill time, hypotension, fever above 39 degrees C and pneumonia. Rapid neutrophil recovery was associated with a good prognosis. A change to our current choice of empirical antibiotics for FN, comprising ceftazidime/ceftriaxone and amikacin appears necessary because of the relatively high resistance rates found.

    Fifty patients with temporomandibular pain dysfunction syndrome were examined. Seventy-eight percent and 32 percent were female and male respectively. The white collar workers were more frequently affected. Emotional stress, dental malocclusion and a history of trauma were the main causes. Treatment consists of reassurance, relaxed jaw movements and exercises, anxiolytic drugs, thermotherapy, biting appliance, occlusal adjustments and restoration of lost dental units.

    Distal renal tubular acidosis (dRTA) caused by mutations of the SLC4A1 gene encoding the erythroid and kidney isoforms of anion exchanger 1 (AE1 or band 3) has a high prevalence in some tropical countries, particularly Thailand, Malaysia, the Philippines and Papua New Guinea (PNG). Here the disease is almost invariably recessive and can result from either homozygous or compound heterozygous SLC4A1 mutations.

    Antimicrobial resistance to the extended-spectrum cephalosporins is increasingly reported worldwide. In the local setting, nosocomial infections with multi-resistant Gram-negative bacilli are not uncommon and are a growing concern. However, there is limited data on the carriage rates of such organisms in the local setting. In May 2001, a prospective study was carried out to determine the enteric carriage rates of ceftazidime-resistant Gram negative bacilli (CAZ-R GNB) among residents of nursing homes and from in-patients of the geriatric and adult haematology wards of University Malaya Medical Centre. Ceftazidime-resistant Gram-negative bacilli (CAZ-R GNB) were detected in 25 samples (30%), out of which 6 were from nursing home residents, 5 from geriatric in-patients and 14 from the haematology unit. A total of 28 CAZ-R GNB were isolated and Escherichia coli (10) and Klebsiella pneumoniae (7) were the predominant organisms. Resistance to ceftazidime in E. coli and Klebsiella was mediated by extended-spectrum beta-lactamases (ESBLs). Although the majority of the CAZ-R GNB were from patients in the haematology ward, the six nursing home residents with CAZ-R GNB were enteric carriers of ESBL-producing coliforms. Prior exposure to antibiotics was associated with carriage of ESBL organisms and to a lesser extent, the presence of urinary catheters.

    Introduction: Thalassaemia is an inherited blood disorder and is a significant public health alarm in Malaysia with many not knowing they are carriers of this haemoglobin disorders. Materials and methods: This study conducted a one off collection of blood samples from 72 Malays students of International Islamic University Malaysia (IIUM) in Kuantan. Blood samples were subjected to conventional haemoglobin analyses that include full blood count and picture, HPLC, Haemoglobin electrophoresis and H-inclusion test. All samples were also genotyped for alpha thalassaemia–1 of Southeast Asia (a-Thal1SEA). Result: There were 17(23.6%) students who were diagnosed as thalassaemia carriers. Out of this, four (5.5 %) and six (8.3 %) students were presumptive β-thalassaemia trait and Haemoglobin-E trait as determined by the HPLC assay respectively. Nine (12.5%) students were genotyped a-Thal1SEA among whom two were also β-thalassaemia carriers. All thalassaemia cases had MCH of < 27pg. Nonetheless, two out of six Haemoglobin-E trait and three out of nine a-Thal1SEA carrier had MCV value of >80fL. Two out of four (50%) presumptive β -thalassaemia trait and one out of six (17%) students of presumptive Haemoglobin-E trait had family history of thalassaemia respectively. Conclusion: The high occurrence of the three common types of thalassaemia carrier (β, Hb-E and a-Thal1SEA thalassaemia) in our small group of subjects could be due to better participation of students who had family history of thalassaemia. The study reaffirmed the importance of molecular study for detection of alpha-thalassaemia and the use of MCH value of

    Hepatitis C is a liver disease caused by the hepatitis C virus: the virus can cause both acute and chronic hepatitis infection. Patients with chronic hepatitis C virus (HCV) infection appear to have an excellent chance of responding to 6 months of standard therapy with interferon (IFN) and frequently develop systemic iron overload, which exacerbates morbidity. The iron excess in hepatitis C may be due to hereditary hemochromatosis, hematologic diseases, multiple transfusions, porphyria cutanea tarda and chronic alcohol abuse. Different mechanisms proposed to explain the relation between HCV infection and hepatic iron overload. Some revealed that hepatic iron accumulation results from release of iron from damaged liver cells. Consumption of coffee, tea also reduces iron absorption and thereby decrease iron overload in Liver and thereby reduces the oxidative stress of iron overload in liver. The global scenario of this problem has been discussed in the article.

    Ralstonia solanacearum species complex phylotype IV strains, which have been primarily isolated from Indonesia, Australia, Japan, Korea, and Malaysia, have undergone recent taxonomic and nomenclatural changes to be placed in the species Ralstonia syzygii. This species contains three subspecies; Ralstonia syzygii subsp. syzygii, a pathogen causing Sumatra disease of clove trees in Indonesia, Ralstonia syzygii subsp. indonesiensis, the causal pathogen of bacterial wilt disease on a wide range of host plants, and Ralstonia syzygii subsp. celebesensis, the causal pathogen of blood disease on Musa spp. In Indonesia, these three subspecies have devastated the cultivation of susceptible host plants which have high economic value. Limited knowledge on the ecology and epidemiology of the diseases has hindered the development of effective control strategies. In this review, we provide insights into the ecology, epidemiology and disease control of these three subspecies of Ralstonia syzygii.

    Mortality level is worsening the situation worldwide thru blood diseases and greatly jeopardizes the human health with poor diagnostics. Due to the lack of successful generation of early diagnosis, the survival rate is currently lower. To overcome the present hurdle, new diagnostic methods have been choreographed for blood disease biomarkers analyses with the conjunction of ultra-small ideal gold nanohybrids. Gold-hybrids hold varieties of unique features, such as high biocompatibility, increased surface-to-volume ratio, less-toxicity, ease in electron transfer and have a greater localized surface plasmon resonance. Gold-nanocomposites can be physically hybrid on the sensor surface and functionalize with the biomolecules using appropriate chemical conjugations. Revolutionizing biosensor platform can be prominently linked for the nanocomposite applications in the current research on medical diagnosis. This review encloses the new developments in diagnosing blood biomarkers by utilizing the gold-nanohybrids. Further, the current state-of-the-art and the future envision with digital monitoring for facile telediagnosis were narrated.

    Background: Unsafe blood products may cause transfusion-transmissible infections. This study aimed to evaluate the knowledge and perceptions of blood donors regarding blood safety.

    Methods: This was a cross-sectional study conducted in the Kelantan state of Malaysia. The questionnaire comprised 39 questions that covered areas such as donors' social demographic information, knowledge of transfusion-transmitted diseases, blood screening and donor eligibility and perceptions towards blood safety. The knowledge score was categorised as good or poor.

    Results: Of the 450 distributed questionnaires, 389 were suitable for analysis. Only 18.5% of the donors had good knowledge, with 81.5% having poor knowledge. Less than 30% were aware that people with multiple sexual partners, bisexual people and male homosexual people are permanently deferred from blood donation. Only 29.4% agreed that donors are responsible if their blood causes infection. Furthermore, 39.3% assumed that they could check their HIV status through blood donation, and 10.3% and 5.4% of the respondents believed that donors are free from infection if they wear a condom during sex or only have oral sex when involved in prostitution, respectively.

    Conclusion: Poor knowledge and notable misperceptions concerning safe blood donation were found among blood donors. The Ministry of Health should incorporate safe blood education in future public awareness programmes.

    Introduction: Increased monocyte percentage and monocyte anisocytosis were suggested as new markers for den- gue fever detection. This study aims to investigate and evaluate monocyte volume standard deviation (MoV-SD) and monocyte percentage (Mono %) parameters using Coulter automated haematology analyser as screening parameters in discriminating between dengue infection and other febrile illness. Methods: A cross-sectional laboratory analysis using suspected dengue fever patients were included in this study. The study was conducted in the Department of Pathology, Hospital Tuanku Jaafar Seremban from June 2016 until June 2017. Patients were classified into dengue positive and dengue negative based on dengue IgM and NS1 result. The diagnostic performance of MoV-SD and Mono % was analysed by receiver operating characteristic (ROC) curve analysis. The cut-off value of the MoV-SD and Mono % was determined and evaluated with the validation group. Chi-square test was used to assess the as- sociation between the parameters. Results: 88 (48.4%) from 182 samples were confirmed to have dengue infection. ROC curve analysis showed Mono % at cut off value of 10.5 % with area under the curve (AUC) of 0.869 with 84.1% sensitivity and 84% specificity (95% CI: 0.812-0.925) and MoV-SD cut off value at 22.2 (AUC 0.776, 80.7% sensitivity, 61.7% specificity, 95% CI: 0.709-0.843) are an excellent parameters in separating dengue positive and dengue-negative patients. A cut-off value of 10.5 of Mono % and 22.2 of MoV-SD were applied to the validation group showed 83.1%, 66.4% sensitivity and 84.9%, 77.3% specificity respectively. Conclusion: MoV-SD and Mono
    % parameters are a potential parameter for the screening of dengue infection in acute febrile illness patients with good specificity and sensitivity.

    Five patients treated with hydroxyurea for various haematological malignancies developed multiple painful oral ulcers. Their neutrophil counts were either normal or elevated. The ulcers disappeared with cessation of hydroxyurea. Oral ulcers recurred when hydroxyurea was resumed in one of the patients. As the patients were unable to tolerate this painful side effect, hydroxyurea had to be discontinued. Appearance of painful oral ulceration seems to be independent of dosing rate or total cumulative dose of hydroxyurea.

    Nipah virus, a novel paramyxovirus, closely related to Hendra virus emerged in northern part of Peninsular Malaysia in 1998. The virus caused an outbreak of severe febrile encephalitis in humans with a high mortality rate, whereas, in pigs, encephalitis and respiratory diseases but with a relatively low mortality rate. The outbreak subsequently spread to various regions of the country and Singapore in the south due to the movement of infected pigs. Nipah virus caused systemic infections in humans, pigs and other mammals. Histopathological and radiological findings were characteristic of the disease. Fruitbats of Pteropid species were identified as the natural reservoir hosts. Evidence suggested that climatic and anthropogenic driven ecological changes coupled with the location of piggeries in orchard and the design of pigsties allowed the spill-over of this novel paramyxovirus from its reservoir host into the domestic pigs and ultimately to humans and other animals.

    OBJECTIVE: Hyperinsulinaemic hypoglycaemia (HH) can occur in isolation or more rarely feature as part of a syndrome. Screening for mutations in the "syndromic" HH genes is guided by phenotype with genetic testing used to confirm the clinical diagnosis. As HH can be the presenting feature of a syndrome, it is possible that mutations will be missed as these genes are not routinely screened in all newly diagnosed individuals. We investigated the frequency of pathogenic variants in syndromic genes in infants with HH who had not been clinically diagnosed with a syndromic disorder at referral for genetic testing.

    DESIGN: We used genome sequencing data to assess the prevalence of mutations in syndromic HH genes in an international cohort of patients with HH of unknown genetic cause.

    PATIENTS: We undertook genome sequencing in 82 infants with HH without a clinical diagnosis of a known syndrome at referral for genetic testing.

    MEASUREMENTS: Within this cohort, we searched for the genetic aetiologies causing 20 different syndromes where HH had been reported as a feature.

    RESULTS: We identified a pathogenic KMT2D variant in a patient with HH diagnosed at birth, confirming a genetic diagnosis of Kabuki syndrome. Clinical data received following the identification of the mutation highlighted additional features consistent with the genetic diagnosis. Pathogenic variants were not identified in the remainder of the cohort.

    CONCLUSIONS: Pathogenic variants in the syndromic HH genes are rare; thus, routine testing of these genes by molecular genetics laboratories is unlikely to be justified in patients without syndromic phenotypes.
