    Serological markers were used to determine the infective agents causing acute viral hepatitis in 246 patients. The frequencies of the five viral infections investigated were: non-A, non-B hepatitis - 99 patients (40.2%); hepatitis A - 98 patients (39.8%); hepatitis B - 43 patients (17.5%); cytomegalovirus - 4 patients (1.6%); and Epstein-Barr virus - 2 patients (0.8%). The log mean ages of presentation for the three predominant infections were: hepatitis A - 18 years; hepatitis B - 25 years; and non-A, non-B hepatitis - 30 years (F = 18.8, p =< 0.001). 52% of all cases were Malays (expected 32. 7%); 32% Chinese (expected 54.6%); and 16% Indians (expected 1l.5%) (X2 = 53, p = < 0.001). Hepatitis A virus infection was more common amongst Malays whilst non-A, non-B hepatitis was more frequent amongst Chinese and Indians. 28% of children <16 years) and 50% of adults had serological markers of previous hepatitis B infection. The variation in frequency for the different forms of hepatitis amongst the three main ethnic groups would suggest that socioeconomic and/or cultural factors are important in the propagation of acute viral hepatitis in Malaysia. HBsAg-negative chronic liver disease in our community may be a product of the high incidence of non-A, non-B hepatitis.

    Paediatric scurvy is uncommon in the modern age but cases have been reported in children with neurodevelopmental issues and restricted dietary habits. The broad clinical picture is frequently overlooked as primarily other systemic diseases are considered first leading to extensive investigations and delay in diagnosis. A 4-year-old boy with autism and bilateral lower limb pain and refusal to walk is reported. His restricted diet and radiographic findings were highly suggestive of scurvy which was confirmed by the extremely low levels of ascorbic acid. Treatment with ascorbic acid replenishment and maintenance resulted in remarkable improvement. This case highlights the importance of a high index of suspicion in at-risk children so as to avoid unnecessary invasive investigations and procedures.

    A prospective study was carried out to evaluate the sensitivity of dengue NS1 antigen-capture ELISA in comparison with dengue virus isolation, conventional RT-PCR and real-time RT-PCR for laboratory confirmation of acute dengue based on single-acute serum samples. Four primary healthcare centres were involved to recruit patients with clinical diagnosis of dengue illness. Patient's demographic, epidemiological and clinical information were collected on a standardized data entry form and 5 ml of venous blood was collected upon consent. In the laboratory, six types of laboratory tests were performed on each of the collected acute serum sample. Of the 558 acute serum samples collected from 558 patients with clinical diagnosis of dengue from mid-August 2006 to March 2009, 174 serum samples were tested positive by the dengue NS1 antigen-capture ELISA, 77 by virus isolation, 92 by RT-PCR and 112 by real-time RT-PCR. A total of 190 serum samples were tested positive by either one or a combination of the four methods whereas, only 59 serum samples were tested positive by all four methods. Thus, based on single-acute serum samples, 190 of the 558 patients (34.1%) were laboratory-confirmed acute dengue. The overall test sensitivity was 91.6%, 40.5%, 48.4% and 58.9% for dengue NS1 antigen-capture ELISA, virus isolation, conventional RT-PCR and real-time RT-PCR respectively. Statistically, dengue NS1 antigen-capture ELISA was the most sensitive and virus isolation was the least sensitive test for the laboratory confirmation of acute dengue based on single-acute serum specimens. Real-time RT-PCR was significantly more sensitive than the conventional RT-PCR.

    We describe a 5-year-old girl who had sudden onset difficulty in walking after 3 days of febrile illness. In the emergency department her creatine kinase level was elevated but urine myoglobin was normal. She was diagnosed as having benign acute childhood myositis. Because of poor oral intake and dehydration, she was admitted to the pediatric ward. The next day she had a petechial rash over the antecubital fossa, and dengue IgM back was positive. She was treated conservatively and recovered uneventfully. Despite dengue fever being endemic in Malaysia, this is the first case report of myositis following dengue infection in Malaysia.

    Perforated appendix is a serious surgical condition that carries a high morbidity. Antibiotic treatment is often started before the availability of bacteriological reports. The choice of antibiotics would depend on the bacteriology associated with perforated appendix. In a retrospective survey of the bacteriology of peritoneal pus obtained from cases of perforated appendix at the General Hospital, Kuala Lumpur, E. coli was found to be the most commonly encountered organism. This was followed in order of decreasing frequency by streptococci, Bacteroides species, Klebsiella-Enterobacter group and Pseudomonas aeruginosa. From the results of the antibiotic sensitivities an antibiotic regimen comprising of a combination of gentamicin, metronidazole and penicillin is recommended as appropriate chemotherapy in perforated appendix.

    A 3-year-old child presented with congenital bilateral facial nerve palsy with bilateral profound sensorineural hearing loss. High Resolution Computed Tomogram (HRCT) of the temporal bones found bilateral atresia of cochlear nerve canals, incomplete partition of the cochleae and narrow facial nerve canals. Magnetic resonance imaging (MRI) revealed bilateral hypoplasia of facial nerves and aplasia of both vestibulocochlear nerves. There have been no other reported cases with this presentation. The possible aetiology and treatment options for the patient are discussed. We highlighted the review of aplasia/hypoplasia of the facial nerve and hypoplasia of cochlear nerve canal.

    OBJECTIVE: This study aimed to evaluate the association between cochlear nerve canal dimensions and semicircular canal abnormalities and to determine the distribution of bony labyrinth anomalies in patients with cochlear nerve canal stenosis.

    METHOD: This was a retrospective study in which high-resolution computed tomography images of paediatric patients with severe-to-profound sensorineural hearing loss were reviewed. A cochlear nerve canal diameter of 1.5 mm or less in the axial plane was classified as stenotic. Semicircular canals and other bony labyrinth morphology and abnormality were evaluated.

    RESULTS: Cochlear nerve canal stenosis was detected in 65 out of 265 ears (24 per cent). Of the 65 ears, 17 ears had abnormal semicircular canals (26 per cent). Significant correlation was demonstrated between cochlear nerve canal stenosis and semicircular canal abnormalities (p < 0.01). Incomplete partition type II was the most common accompanying abnormality of cochlear nerve canal stenosis (15 out of 65, 23 per cent).

    CONCLUSION: Cochlear nerve canal stenosis is statistically associated with semicircular canal abnormalities. Whenever a cochlear nerve canal stenosis is present in a patient with sensorineural hearing loss, the semicircular canal should be scrutinised for presence of abnormalities.

    OBJECTIVE: The purpose of this study was to compare the reliability and accuracy of chirp-based Multiple Auditory Steady State Response (MSSR) and Auditory Brainstem Response (ABR) in children.

    METHODS: The prospective clinical study was conducted at Selayang Hospital (SH) and Hospital Canselor Tuanku Muhriz (HCTM) within one year. A total of 38 children ranging from 3 to 18 years old underwent hearing evaluation using ABR tests and MSSR under sedation. The duration of both tests were then compared.

    RESULTS: The estimated hearing threshold of frequency specific chirp MSSR showed good correlation with ABR especially in higher frequencies such as 2000 Hz and 4000Hz with the value of cronbach alpha of 0.890, 0.933, 0.970 and 0.969 on 500Hz, 1000Hz, 2000Hz and 4000Hz. The sensitivity of MSSR is 0.786, 0.75, 0.957 and 0.889 and specificity is 0.85, 0.882, 0.979 and 0.966 over 500Hz, 1000Hz, 2000Hz and 4000Hz. The duration of MSSR tests were shorter than ABR tests in normal hearing children with an average of 35.3 minutes for MSSR tests and 46.4 minutes for ABR tests. This can also be seen in children with hearing loss where the average duration for MSSR tests is 40.0 minutes and 52.0 minutes for ABR tests.

    CONCLUSION: MSSR showed good correlation and reliability in comparison with ABR especially on higher frequencies. Hence, MSSR is a good clinical test to diagnose children with hearing loss.

    The cross sectional study was conducted in Universiti Kebangsaan Malaysia Medical Center (UKMMC), Malaysia from August 2012 to December 2013. All patients implanted with in UKMMC from December 2001 until December 2012 was included. Glasgow Benefit Inventory (GBI) questionnaires and UKMMC questionnaires were used as part of the assessment tool. The GBI is a scoring which measures the change in health status produced by surgical interventions. UKMMC questionnaires was invented by our department to assess questions related to social and life style of patients and also the cosmetic perspective Baha implant and other daily related activities. The audiological assessment was assessed using hearing aid gain threshold. Complication with regards to skin reaction was graded using Holger Skin Classification. A total of 40 patients underwent Baha implant were recruited but only 35 patients fulfilled the criteria and included in this study for analysis. Age of patients ranged from 5 year old to 38 year old, with median of 13 years old. There were 22 patients (62.8%) were male and 13 patients (37.1%) were females. Almost all cases were canal atresia except one adult patient was a case of bilateral chronic discharging ear with chronic irritation with ear mould. Majority of patients 21 (60%) have hearing level of moderate to severe hearing loss (40-89 dB) and 14 patients (40%) have mild to moderate hearing loss (20-39 dB). The level of hearing was retested post operatively. All of the patients have improvement in their aided hearing with the range of 10-25 dBL which is statistically significant at p value of <0.05. The GBI was scored positively in all subscales. Majority of patients (91.4%) used BAHA more than 4 h per day and 88.6% agreed that BAHA is cosmetically acceptable. All patients experienced some form of skin irritation (Holger grade 1-2) however only 20% required surgical intervention. All our patients have range of 10-25 dB improvement of their aided hearing which is statistically significant at p value of <0.05. BAHA has been proven to show significant benefit in audiological improvement and quality of life.

    Minor illnesses in children are often cured at home with over the counter medicines. Even though there is a wide use of medicines among children, they rarely receive medical advice about their medications from doctors or pharmacists. The aim of this study is to evaluate children's beliefs about medicines as well as to explain what children know about medicines. A cross-sectional survey was used to collect data from four primary schools in Penang Island, Malaysia. The target population of this research was schoolchildren of 11 and 12 years old regardless of their gender and social status. A self-administration questionnaire was used to obtain the data from schoolchildren and their parents. After including all schoolchildren in grades five and six, the total sample size was 1000 children in addition to 1000 parents. This study found that most children have inadequate knowledge and false beliefs about the efficacy of medicines. Children's beliefs about the efficacy of medicines were affected by their age group, gender and race (p

    Pilus has been recently associated with pneumococcal pathogenesis in humans. The information regarding piliated isolates in Malaysia is scarce, especially in the less developed states on the east coast of Peninsular Malaysia. Therefore, we studied the characteristics of pneumococci, including the piliated isolates, in relation to antimicrobial susceptibility, serotypes, and genotypes at a major tertiary hospital on the east coast of Peninsular Malaysia. A total of 100 clinical isolates collected between September 2017 and December 2019 were subjected to serotyping, antimicrobial susceptibility test, and detection of pneumococcal virulence and pilus genes. Multilocus sequence typing (MLST) and phylogenetic analysis were performed only for piliated strains. The most frequent serotypes were 14 (17%), 6A/B (16%), 23F (12%), 19A (11%), and 19F (11%). The majority of isolates were resistant to erythromycin (42%), tetracycline (37%), and trimethoprim-sulfamethoxazole (24%). Piliated isolates occurred in a proportion of 19%; 47.3% of them were multidrug-resistant (MDR) and a majority had serotype 19F. This study showed ST236 was the most predominant sequence type (ST) among piliated isolates, which was related to PMEN clone Taiwan19F-14 (CC271). In the phylogenetic analysis, the piliated isolates were grouped into three major clades supported with 100% bootstrap values. Most piliated isolates belonged to internationally disseminated clones of S. pneumoniae, but pneumococcal conjugate vaccines (PCVs) have the potential to control them.

    Sixty patients with brain abscess were treated at the Neurosurgical Unit of the Department of Surgery, Hospital Universiti Sains Malaysia between January 1990 and December 1996. A retrospective study was done and data were collected from the computerise d registry of the Record Unit of Hospital Universiti Sains Malaysia. Good results were achieved in patients who were both treated surgically and medically. There were only twelve deaths in this group. The main factor that influences morbidity and mortality of brain abscess is the clinical presentation on admission. The mortality was high in patients treated solely by medical means. Death was common in patients who presented with acute onset of symptoms of less than one week duration and those with poor mental status. Brain abscess is common in the East Coast population of peninsular Malaysia, probably due in part to lower socioeconomic status. Efforts should be directed towards prevention of infection and early recognition and management.

    Traumatic chronic subdural hematomas in Malaysia are increasingly common in young patients after road traffic accidents as well as the elderly who fall at home. Most surgeons in this country manage these pathologies without irrigation, with only a drainage system. This has led to criticism that the recurrence rate might be higher when no irrigation is done and that rates are lower with irrigation and drainage. Thus, a study was done to look into the outcome of TCSH operated with and without irrigation, followed by drainage, to guide the surgeons in Malaysia as to what best could be done for these cases.

    Frequent loss of heterozygosity (LOH) and mutations of the tumor suppressor gene PTEN (phosphatase and tensin homologue deleted from chromosome 10) have been found in sporadic gliomas. The most documented regions of allelic losses include 9p21, 10q23-25 and 17p1 3 whereas PTEN aberrations are preferentially found in glioblastoma multiformes. This research aimed to detect the incidence of allelic losses on chromosomes 10q, 9p, 17p and 13q and mutations on exons 5, 6 and 8 of PTEN in malignant gliomas. Malignant glioma specimens obtained were classified histopathologically according to the WHO criteria. Each tumor was then subjected to polymerase chain reaction (PCR)-LOH analysis using microsatellite markers and single-stranded conformational polymorphism (SSCP) analysis. Twelve of 23 (52%) malignant glioma cases showed allelic losses whereas 7 of 23 (30%) samples showed aberrant band patterns and mutations of PTEN. Four of these cases showed LOH in 10q23 and mutations of PTEN. The data on LOH indicated the involvement of different genes in the genesis of glioma whereas mutations of PTEN indicated the role of PTEN tumor suppressor gene in the progression of glioma in Malay population.

    Recent advances in neuro-oncology have revealed different pathways of molecular oncogenesis in malignant gliomas including loss of heterozygosity on chromosomal regions harboring tumor suppressor genes. In the present study, we performed polymerase chain reaction-loss of heterozygosity (PCR-LOH) analysis using microsatellite markers to identify loss of heterozygosity on chromosomes 10q, 9p, 17p and 13q in the Malays with malignant gliomas. Of 12 cases with allelic losses, seven (58.3%) cases showed LOH on chromosome 10q, three (25.0%) cases showed LOH on chromosome 9p, four (33.3%) cases showed LOH on chromosome 17p and two (16.7%) cases showed LOH on chromosome 13q. The cases include five (41.7%) cases of glioblastoma multiforme, three (25.0%) cases of anaplastic astrocytoma, three (25.0%) cases of anaplastic oligodendroglioma and one (8.3%) case of anaplastic ependymoma. Four cases showed loss of heterozygosity on more than one locus. Our findings showed that loss of heterozygosity on specific chromosomal regions contributes to the molecular pathway of glioma progression in Malay population. In addition, these data provide useful evidence of molecular genetic alterations of malignant glioma in South East Asian patients, particularly in the East Coast of Malaysia.

    OBJECTIVE: Subgaleal drains are generally deemed necessary for cranial surgeries including decompressive craniectomies (DCs) to avoid excessive postoperative subgaleal hematoma (SGH) formation. Many surgeries have moved away from routine prophylactic drainage but the role of subgaleal drainage in cranial surgeries has not been addressed.

    METHODS: This was a randomized controlled trial at 2 centers. A total of 78 patients requiring DC were randomized in a 1:1:1 ratio into 3 groups: vacuum drains (VD), passive drains (PD), and no drains (ND). Complications studied were need for surgical revision, SGH amount, new remote hematomas, postcraniectomy hydrocephalus (PCH), functional outcomes, and mortality.

    RESULTS: Only 1 VD patient required surgical revision to evacuate SGH. There was no difference in SGH thickness and volume among the 3 drain types (P = 0.171 and P = 0.320, respectively). Rate of new remote hematoma and PCH was not significantly different (P = 0.647 and P = 0.083, respectively), but the ND group did not have any patient with PCH. In the subgroup analysis of 49 patients with traumatic brain injury, the SGH amount of the PD and ND group was significantly higher than that of the VD group. However, these higher amounts did not translate as a significant risk factor for poor functional outcome or mortality. VD may have better functional outcome and mortality.

    CONCLUSIONS: In terms of complication rates, VD, PD, and ND may be used safely in DC. A higher amount of SGH was not associated with poorer outcomes. Further studies are needed to clarify the advantage of VD regarding functional outcome and mortality, and if ND reduces PCH rates.

    We reviewed various studies regarding human toxoplasmosis in Malaysia. They showed a varying prevalence of specific Toxoplasma antibodies among the Malaysian population. The Malays have shown the highest seroprevalence of toxoplasmosis, by most studies, when compared to other races. Demographic profiles have shown that Toxoplasma seropositivity is higher in males than females, lower in people with higher incomes, higher in the unemployed and tends to increase with age. In general, the route of transmission, such as contact with a cat, consumption of undercooked meat and blood transfusion were shown to have no significant association with Toxoplasma seropositivity (p > 0.05). The immune status (CD4 cell count < 200 cell/mm3) was strongly associated with toxoplasmic encephalitis (p < 0.05).

    Informal human milk exchange is the practice of donating and receiving expressed human milk based on mutual consent between the donor and receiver in the need of human milk for infants below 2 years old. Main concerns related to informal human milk exchange is related to milk siblings and safety handling of the expressed breastmilk. Even though there are countries which have policies and procedures related to human milk bank, informal milk exchange has not been given much attention. Compared to human milk bank, informal human milk exchange is not regulated. This study aims to identify the system focused on personalized breastfeeding tracking and monitoring, online discussion forum, web-based consultation, and breastfeeding station locator. Review of current applications in supporting breastfeeding practices was conducted based on the PRISMA-ScR framework. A literature search was conducted in Scopus and Google Scholar databases to identify articles published in English or Malay and containing systems/applications related to breastfeeding, milk sharing, milk exchange, milk siblings/kinship within the societal context. According to the scoping review, current scientific publications mostly focused on breast milk, breastfeeding, and milk banking concerns, with recurring themes including social reasons, lactation insufficiency, and unsolved nursing problems. These themes highlight the complexities and complexities of informal human milk exchange practices. Two reviewers screened the articles, and the data were extracted and narratively synthesized. During the primary database search, 360 articles were found based on the related titles, abstracts, and keywords. Seventy eight met the inclusion criteria and were finalized in this review. We found that most scholarly works focused on breast milk, breastfeeding and milk banking challenges and issues with recurrent themes i.e., societies, lactation inadequacy and unresolved nursing problems. Based on our literature search and to the best of our knowledge, there is no recent scoping reviews which focuses on technology-based approaches on informal human milk exchange. Findings from this scoping review is important for advancing research and practice in this field, as well as improving outcomes for individuals and families affected by informal human milk exchange.
