    Dengue is endemic in over 100 countries worldwide, predominantly in the subtropical and tropical regions and the incidence has been increasing globally. Patients with severe dengue may develop massive bleeding, disseminated intravascular coagulopathy and multi-organ failure. Bleeding may occur in various body cavities and muscles; however, bleeding in the retroperitoneal space is uncommon. We report a case of a 37-year-old gentleman who presented with a 4-day history of fever associated with chills and rigours. On Day 6 of illness, he complained of left lumbar and left iliac fossa pain which was aggravated by movement. A computed tomography angiography scan of the abdomen showed the presence of a retroperitoneal haematoma, left iliopsoas and quadratus lumbarum intramuscular haematoma with active bleeding and left abdominal wall muscles haematoma. His condition gradually improved after multiple blood transfusions and he gained full recovery. Spontaneous retroperitoneal haematoma is an uncommon complication of severe dengue infection. Early diagnosis based on high index of clinical suspicion using appropriate imaging will aid in prompt management of these cases and may prevent deaths.

    Familial myelodysplastic syndrome occurring at a young age is a very rare childhood haematological malignancy. Two siblings, aged three and 18 years, from a consanguineous marriage, presented with pancytopenia and was subsequently diagnosed to have myelodysplastic syndrome. Both remained clinically stable throughout the illness. Splenectomy appeared to have fully corrected the cytopenia in one of them.

    H-deficient phenotype individuals with absent or weak anti-H activity may remain undetected on standard routine blood grouping. We report a case of a 59-year-old-man presented with symptomatic anaemia secondary to upper gastrointestinal bleed with haemoglobin level of 68 g/L who required two units of packed red blood cells. He was previously grouped as O Rh D positive and had a history of uneventful multiple blood transfusions. His latest pre-transfusion investigations showed ABO discrepancy between forward and reverse blood grouping, pan-agglutination in both antibody screening and identification with negative direct Coombs test and autocontrol. Further testing including anti-H lectin test and saliva secretor study confirmed that the patient blood group was para-Bombay B RhD positive. This case highlights that the para-Bombay phenotype can be mistakenly labelled as "O" if further investigations are not performed.

    CAD accounts for 25% of mortality in Malaysia public hospitals. CABG is one of treatment for patients with CAD, but requires RBC transfusion, which is associated with morbidity and mortality. This study was to evaluate the association between RBC transfusion and morbidity and mortality in CABG patients at the National Heart Centre, Malaysia (IJN). Methods: Retrospective cross-sectional study performed using data from 434 patients who underwent CABG in 2013 and 2014. Subjects had systematic random sampling every fifth subject of the patients in the sequence of dates of the year. Data related to the relationship between RBC transfusion with mortality and morbidity, and the predicting factors captured. Results: 64.3% of CABG patients (n = 279) received RBC transfusion perioperatively. Age, gender, BMI, and EF, were factors that contributed for RBC transfusion. RBC transfusion was a contributor to longer intensive care unit length of stay (ICULOS) and hospital length of stay (HLOS). Multiple logistic regression revealed, for every 1 year increase of age, there is 3.5% higher chance of transfusion. Whereas an increase of 1 kg/m2 of BMI and 1% of EF reduced the odds of RBC transfusion by 13.0% and 3.0% respectively. Conclusions: Age, gender, BMI, and EF determine the probability of needing RBC transfusion during CABG, and RBC transfusion will result in longer ICULOS, and HLOS. Probability of RBC transfusion will be higher in older patients and reduced in those with higher BMI and EF.

    Introduction Hepatitis C Virus (HCV) recently was identified as a major cause of post transfusion hepatitis world wide. To evaluate the role of blood transfusion on the prevalence of HCV infection, by testing antibody and RNA as well as the genotypes of HCV .Also to detect if Blood transfusion acts as unconfounding risk factor for HCV infection.
    Methods Sera from 3491 pregnant women were investigated for the presence of HCV antibodies (anti-HCV) by using third generation enzyme immunoassay (EIA-3) as screening test, followed by immunoblot assay (Lia Tek-III). In addition 94 sera of studied women were subjected to molecular analysis (at laboratories of Sorin BioMedica - Italy) for the detection of viral RNA and genotypes of HCV. Using RT-PCR & DNA Enzyme immunoassay (DEIA) method.
    Results Our study revealed, that seroprevalence rate of HCV specific Ab & RNA were significantly higher (16.32 %, 80% respectively) among women with a history of blood transfusion, compared to those (2.53%, 56.5%) with no such history P=0.0001, P=0.01. And there is a significant direct linear correlation between number of blood transfused and the seropositive rate of anti-HCV (r=0.7, p=0.046). Based on multivariate analysis, interestingly, this study confirmed that, blood transfusion significantly acting as unconfounding risk factor for acquiring HCV infection (Adjusted OR=1.938,95% C.I=1.646-2.28). And the risk of exposure is increases with increased number of blood transfused. Although, we found no significant association between, HCV genotypic distribution and history of blood transfusion. However, high proportion of women with a history of blood transfusion were harboring HCV genotype -4 or 1b, 50%,40%, resepctively.
    Conclusions Our study shows, evidence that, blood transfusion acts as unconfounding risk factor for acquiring and in a mode of transmission of HCV infection. Therefore strict screening of blood donor for HCV-Abs and / or RNA is highly recommended.

    ABO blood grouping is an important antigenic blood typing tools in blood transfusion and organ transplants. Mismatching of blood during transfusion would lead to undesired transfusion reactions. Due to rare occurrence of rare blood group such as A2 subtype, regular blood grouping technique would have missed the identification of blood group. Objectives: In this study, the identification of A2 subgroup using routine serological technique was validated via DNA sequencing technique. Materials and Methods: A total of 656 students participated in this study consist of Malay (87.0 %), Chinese (0.4 %), Indian (11.4 %) and others ethnic group (0.9%) respectively. Monoclonal antisera A, B, AB, D, A1 lectin and H lectin were used to identify the antigen on red blood cells. DNA sequence analysis was applied to examine single nucleotide polymorphisms (SNPs) at position 467 (substitution of C>T) and 1061 (deletion of C) on coding region of ABO gene. Results: Our findings showed of 656 blood samples, 256 (39.0%) were blood group O, 190 (29.0%) were blood group B, 179 (27.3%) were blood group A and 31(4.7%) were blood group AB. The frequency of A1 subgroup is 177 (99.0%) and A2 subgroup is 2 (1.0%). From 179 A blood group, only 2 samples showed negative reaction towards anti-A1 lectin. DNA sequence analysis revealed the SNPs at nucleotide 1061 position in sample 2, however this mutation was absence in sample 1, suggesting presence of another mutation that may result in the A2 phenotype. Conclusion: The current study reported the absence of 1061C deletion in A2 blood group sample among Malaysian population.

    Malaria may be a serious complication of blood transfusion due to the asymptomatic persistence of parasites in some donors. This case report highlights the transfusion-transmitted malaria of Plasmodium vivax in a child diagnosed with germ cell tumour. This child had received blood transfusion from three donors and a week later started developing malaria like symptoms. Nested PCR and sequencing confirmed that one of the three donors was infected with P. vivax and this was transmitted to the 12-year-old child. To the best of the authors' knowledge, this is the first reported transfusion-transmitted malaria case in Malaysia.

    Hemovigilance like quality systems and audits has become an integral part of the Blood Transfusion Service (BTS) in the developed world and has contributed greatly to the development of the blood service. However developing countries are still grappling with donor recruitment and efforts towards sufficiency and safety of the blood supply. In these countries the BTS is generally fragmented and a national hemovigilance program would be difficult to implement. However a few developing countries have an effective and sustainable blood program that can deliver equitable, safe and sufficient blood supply to the nation. Different models of hemovigilance program have been introduced with variable success. There are deficiencies but the data collected provided important information that can be presented to the health authorities for effective interventions. Hemovigilance program modeled from developed countries require expertise and resources that are not available in many developing countries. Whatever resources that are available should be utilized to correct deficiencies that are already apparent and obvious. Besides there are other tools that can be used to monitor the blood program in the developing countries depending on the need and the resources available. More importantly the data collected should be accurate and are used and taken into consideration in formulating guidelines, standards and policies and to affect appropriate interventions. Any surveillance program should be introduced in a stepwise manner as the blood transfusion service develops.

    Thalassaemia is a life-long illness that exists globally. The quality of life of adolescents with thalassaemia could differ based on the health policies of a specific region, existing levelof socio-economic development and the illness related variables. This study examines the relationship between socio-demographic and disease-related variables with the quality of life among adolescents with thalassaemia involving multiple treatment centers spread throughout various locations in Malaysia. Participants included 218 adolescents (male=108; female 112) with mean age of 13.86 (SD=2.40). They completed the questionnaire consisting of demographic information, illness-related variables, and Pediatric Quality of Life Inventory 4.0 (PedsQL). The participants in this study was found to have higher total summary score (Mean = 69.64, SD = 14.03), psychosocial health (Mean = 70.23, SD = 14.91), emotional (Mean = 72.12, SD = 20.66), social (Mean = 79.82, SD = 17.37), and school (Mean = 58.69, SD = 16.77) functioning but with lower physical health (Mean = 68.50, SD = 17.22) as compared to previous study that was done in Kuala Lumpur. Findings also shows a significant positive correlation between level of education and frequency of hospitalization (r = .156, p < 0.05), frequency of transfusion (r = .152, p < 0.05), and physical health (r = .186, p < 0.01). An increase in the frequency of transfusion was found to significantly increase social functioning (r = .137, p < 0.05). Other significant correlations are discussed in addition to the quality of life experienced by patients with thalassaemia in different region of theworld.

    A prospective observational study was carried out over a seven month period in the neonatal intensive care unit (NICU) of a large Malaysian maternity hospital to determine the rate of blood transfusion and the incidence of transfusion reactions in newborn infants. During the study period, the rates of blood transfusion was 6.1% (n = 117) of NICU admission or 8.2 per 1,000 live births. The median birth weight of the infants who had received blood transfusion was 1,740 grams (range: 725-4,350), and their mean gestational age was 33.6 weeks (sd = 5.1, range = 24-41 weeks). The median age of infants when they first received blood transfusion was 4.0 days (range: 1-27 days). When compared with infants of birth weight between 3,000 and 3,499 grams, infants of birth weight less than 1,500 grams received significantly higher median number of transfusions per infant, (p < 0.001). The incidence of transfusion reaction was 2.7% (3/110) of all transfused infants or 1.3% (3/223) of all blood transfusions. Febrile nonhemolytic reaction was the only type of transfusion reaction detected during the study period. This study showed that transfusion reactions in newborn infants were not common.

    OBJECTIVE: To assess the learning curve of a dual attending surgeon strategy in severe adolescent idiopathic scoliosis patients.

    SUMMARY OF BACKGROUND DATA: The advantages of a dual attending surgeon strategy in improving the perioperative outcome in scoliosis surgery had been reported. However, the learning curve of this strategy in severe scoliosis had not been widely studied.

    METHODS: A total of 105 patients with adolescent idiopathic scoliosis with Cobb angle of 90° or greater, who underwent posterior spinal fusion using a dual attending surgeon strategy were recruited. Primary outcomes were operative time, total blood loss, allogeneic blood transfusion requirement, length of hospital stay from time of operation and perioperative complications. Cases were sorted chronologically into group 1: cases 1 to 35, group 2: cases 36 to 70, and group 3: case 71 to 105. Mean operative time (≤193.3 min), total blood loss (≤1612.2 mL), combination of both and allogeneic blood transfusion were the selected criteria for receiver operating characteristic analysis of the learning curve.

    RESULTS: The mean Cobb angle was 104.5° ± 12.3°. The operative time, total blood loss, and allogeneic blood transfusion requirement reduced significantly for group 1 (220.6 ± 54.8 min; 2011.3 ± 881.8 mL; 12 cases) versus group 2 (183.6 ± 36.7 min; 1481.6 ± 1035.5 mL; 3 cases) and group 1 versus group 3 (175.6 ± 38.4 min; 1343.7 ± 477.8 mL; 3 cases) (P blood loss) (area under the curve 0.740; P blood loss when comparing group 1 versus group 2 and group 1 versus group 3. The cut-off point for the learning curve was 57 cases when the preset criteria were fulfilled (≤193.3 min operative time and ≤1612.2 mL of total blood loss).Level of Evidence: 4.

    INTRODUCTION: Thalassemias are the most common human monogenic disorders in the world. Regular blood transfusion and increased intestinal absorption of iron among thalassemia patients will lead to iron overload, which will not only markedly decrease their life expectancy but also pose a heavy burden to the healthcare system. The objective of this study was to evaluate the level of knowledge, attitude and practice towards dietary iron among thalassemia patients and their caregivers.

    METHODS: An analytical cross-sectional study using purposive sampling method was conducted at eight thalassemia societies in Peninsular Malaysia. 260 respondents comprised of patients and caregivers were assessed with two separate sets of questionnaires.

    RESULTS: Knowledge on dietary iron among the respondents was unsatisfactory, despite them having good knowledge on thalassemia disorder. Female patients were found to have better dietary knowledge, attitude and practice compared to males. The percentage of caregivers with good attitude and good practice were significantly higher compared to adult patients. Caregivers with children on iron chelators were noted to have better dietary attitude and practice. Thalassemia knowledge and children on vitamins were found to be the predictors of dietary knowledge among the patients and caregivers respectively.

    CONCLUSION: The level of knowledge on dietary iron among the patients and caregivers was unsatisfactory in spite of their attitude and practice towards dietary iron were good. Effective delivery of dietary information to the patients and caregivers is essential to enable them to choose a healthy diet for their condition.
