Cholestatic disorders of infancy (viz neonatal hepatitis and biliary atresia) have not been well studied in Malaysia. In a retrospective study in the Department of Paediatrics, University Hospital, Kuala Lumpur from January 1982 through December 1991, a total of ninety-three infants with such conditions were identified: 35 (38%) had biliary atresia, 58 (62%) neonatal hepatitis. There was a statistically significant male preponderance in the neonatal hepatitis group (P = 0.020). There was no significant difference in the racial distribution and in the proportions of low birthweight infants between the two groups of disorders. When the biliary atresia group was compared with the neonatal hepatitis group, significant differences were observed in the age of presentation (mean +/- SD) 9.8 +/- 6.8 VS 20 +/- 17.3 weeks (P < 0.001), proportion of infants with prolonged jaundice (> seven weeks) 28/35 (80%) VS 20/58 (34.5%) (P < 0.00001), occurrence of alcoholic stools 26/35 (74.3%) VS 27/58 (46.6%) (P = 0.020), liver size (mean +/- SD): 4.3 (1.6 cm VS 3.3 +/- 1.8 cm (P < 0.01) and splenic size: 2.5 (1.8 cm VS 1.4 (1.2 cm (P < 0.001). There was however considerable overlap between the two groups in these features at presentation, making clinical differentiation between the two conditions difficult. Infants with cholestasis tended to present late, compromising the chance of survival. In order to improve the medical care of these patients, these conditions must be emphasised during the training of medical practitioners, and efforts to increase public awareness of these conditions must be created.
In a study of 1,002 consecutive Malaysian male newborns, 48 (4.8%) were found to have undescended testes (UDT). The rate and laterality of the UDT were associated with lower birth weight (P < 0.001) and prematurity (P < 0.001). Boys with UDT were also more likely to have other congenital abnormalities of the external genitalia, the commonest being hydrocele. No correlation between UDT and maternal age, birth order, social class, or mode of delivery was demonstrated in this study. Although 26/34 (76.5%) of UDT achieved full spontaneous descent by 1 year of age, 1.1% of all infants whose testes remained undescended required regular long-term follow-up with surgical referral and correction at an appropriate time. A premature infant with UDT is more likely to achieve full testicular descent at 1 year of age than a term infant.

Rhabdomyolysis is a syndrome with a wide range of symptoms ranging from asymptomatic raised serum creatinine kinase to life-threatening metabolic disturbances and acute kidney injury. A careful history taking and high clinical suspicion on drug-drug interaction are crucial to identify the etiology of rhabdomyolysis. Here, we present a case of rhabdomyolysis due to a rare drug-to-drug interaction of simvastatin, diltiazem, and cyclosporin in a patient with IgA nephropathy. Early renal replacement therapy was initiated, and the insulting agents were withheld. Despite the metabolic disturbances were corrected, the patient succumbed to possible venous thromboembolism event during the prolonged hospital stay. Therefore, heightened awareness is required in dealing with patients with glomerulonephritis who are frequently prescribed on polypharmacy, in order to reduce unwarranted adverse events.
Extensive haemangioma with platelet consumption (Kasabach-Merritt syndrome) is rare. The lesion is usually a single cutaneous cavernous haemangioma similar to that found in our patient. Multiple superficial strawberry naevi were also seen all over the rest of the body. This condition was diagnosed antenatally in this patient with the use of colour Doppler. There is one recent report where the thrombocytopaenia was diagnosed by cordocentesis. Unfortunately the baby developed heart failure with intractable coagulopathy and died 2 days later.
Cerebro-costo-mandibular syndrome (CCM) is a very rare entity with oro-facial features closely resembling Pierre-Robin anomaly (1,2). We describe a patient with typical features: severe micrognathia, glossoptosis, central cleft soft palate and multiple posterior rib-gap defects seen on chest radiograph. Respiratory distress which was evident soon after birth was relieved by an oro-pharyngeal airway. He suffered from a cardiorespiratory arrest and succumbed, presumably secondary to aspiration of milk feeds, before a tracheostomy could be performed.
Pregnancies conceived through assisted reproduction can present considerable management problems to the obstetric and paediatric staff. Multiple pregnancies are common. The complication of prematurity increases the morbidity and mortality rates of the neonates.
We retrospectively studied the records of 6 Malaysian children who were diagnosed with Alagille Syndrome (AGS) according to this criteria from January 1999 to January 2001, at the Institute of Paediatrics, Kuala Lumpur Hospital. Four patients (66%) had a positive family history. Thirteen individuals (6 patients and 7 relatives) were diagnosed with AGS in these 5 families. Only 6/13 (46%) of them presented with liver involvement. All 6 patients presented with typical facies and cholestasis (100%). Three (50%) presented with portal hypertension (PHT) with synthetic liver dysfunction (1 died), 1/6 (17%) have PHT and normal synthetic liver function. Two have cleared their jaundice but have biochemical evidence of hepatitis and hepatomegaly, four have congenital heart disease 5/6 posterior embryotoxon, 2/6 butterfly vertebrae, 4/6 hyperlipidaemia and 4/6 failure to thrive. One patient has a Jagged-1 gene disruption at the translocation breakpoint locus 20p12.3 2n = 46,XX,t(12.20) (q22, p12.3). 5/6 (83%) are still alive. Two-thirds of our patients developed chronic liver disease by 3 years of age. Two-thirds of the index patients have a family history. Only 46% of individuals in these families have clinical evidence of liver involvement. Mortality depends on cardiac/renal disease, end-stage liver failure and intercurrent infection.
AIMS: To examine the pattern of and the influence of some socio-demographic factors on infant milk feedings, and the protective role of breastfeeding against infections.
METHODS: Mothers who breastfed their infants (exclusively or partially) at 6 weeks postpartum, and who had singleton pregnancies and healthy infants at birth, were interviewed when their infants had reached 6 months of age.
RESULTS: Of the 234 mothers studied, only 31 (13%) mothers were practising exclusive breastfeeding (EBF) and 133 (57%) mothers were using exclusive infant formula feeding (EIF). Solid and semi-solid foods were introduced between 4 to 6 months of life in 89% of the infants. On logistic regression analysis, mothers who were in paid employment [OR 0.25, 95% CI 0.15, 0.42] and not breast feeding at 6 weeks [OR 0.32, 95% CI 0.19, 0.54] had decreased odds of EBF. Antenatal plans to breastfeed, breast-feeding difficulties, ethnicity, level of parental education, parental ages, fathers' income, primigravida status and infants' gender were not significant co-variates. In comparison, EIF was more likely in mothers who worked, practised mixed feedings at 6 weeks and of Chinese descent. There were no significant differences in the rates of upper respiratory tract infections (URTI) or diarrhoeal illnesses between the infants who were or were not being breast-fed.
CONCLUSIONS: Most mothers were unable to breastfeed their infants exclusively in the recommended first 4 to 6 months of life. Complementary changes outside the hospital and maternity services are essential in improving breastfeeding rates. Breastfeeding does not appear to confer significant protection to either URTI or gastrointestinal tract infections.

While it is not difficult to recognise the classical clinical features of congenital syphilis in most cases, some of them may present with unusual manifestations which can defy early diagnosis. We report our experience with 13 cases of early congenital syphilis over a period of 10 years from 1980 to 1989. Twelve of the thirteen patients were less than 3 months at presentation. There were two infants born prematurely and six of the babies were born with a low birthweight (less than 2.5 kg). All but four patients survived following treatment. Skin lesions either in the form of typical vesiculobullous eruption over the palms and soles or a maculopapular skin rash over the body were the most common presentation and was seen in 10 patients. Splenomegaly with or without hepatomegaly was the most consistent physical sign. Radiological changes in the form of periostitis and/or metaphysitis were seen in all cases where an X-ray of the long bones was performed. An elevated serum immunoglobulin M, though non-specific for the disease, was found to be a useful screening test for recent infection.
Chinese national music is unique to China, and in the past, the single means of distribution and the audience led to the fact that knowledge of Chinese culture and history was limited to national musicians and a subset of fans. With the rapid development of the internet, the dissemination of Chinese national music is no longer limited to live performances, but is beginning to shift to media platforms. Social media has had a tremendous impact on Chinese music culture; people can search for any information they need about Chinese music. With the advancement of social media, groups of internet celebrities such as wanghong () have formed on the internet. This study systematically reviews platformisation and the social media in Chinese national music. Past literature and current notions on Chinese national music development under platformisation are examined given the essentiality of smart devices in developing music through digital technology. The study posed three research questions: 1.What is the current state of development of Chinese national music? What opportunities does platformisation bring to Chinese national music? 2.What areas are the focus for research on platformisation and social media? What is the impact on the music field? 3.What is the history of the development of the Chinese wanghong phenomenon? What impact has it made on Chinese national music? A general systematic review of scholarly articles was conducted for this study using multiple publications from reputable databases: Scopus, Web of Science and CNKI (China National Knowledge Infrastructure). The articles were categorised based on scholarly works involving platforms, platformisation, Chinese national music, social media, and wanghong to determine past study profiles in this domain and relevant knowledge gaps.
Chinese knotweed (Persicaria chinensis) is of ecological and economic importance as a high-risk invasive species and a traditional medicinal herb. However, the insects associated with P. chinensis pollination have received scant attention. As a widespread invasive plant we would expect P. chinensis to be associated with a diverse group of insect pollinators, but lack of taxonomic identification capacity is an impediment to confirm this expectation. In the present study we aimed to elucidate the insect pollinators of P. chinensis in peninsular Malaysia using DNA barcoding. Forty flower visitors, representing the range of morphological diversity observed, were captured at flowers at Ulu Kali, Pahang, Malaysia. Using Automated Barcode Gap Discovery, 17 morphospecies were assigned to 23 species representing at least ten families and four orders. Using the DNA barcode library (BOLD) 30% of the species could be assigned a species name, and 70% could be assigned a genus name. The insects visiting P. chinensis were broadly similar to those previously reported as visiting Persicaria japonica, including honey bees (Apis), droneflies (Eristalis), blowflies (Lucilia) and potter wasps (Eumedes), but also included thrips and ants.
Thirty preterm infants weighing > or = 800 g with clinical and radiological evidence of respiratory distress syndrome (RDS) requiring mechanical ventilation with FiO2 of > or = 40% were given modified bovine surfactant (Survanta). They were compared with equal number of historical controls. Infants who received surfactant showed prompt and highly significant improvement in FiO2, mean airway pressure, arterial/alveolar oxygen tension ratio and ventilatory index. There was significant improvement in mortality rate (10% vs 33%; p = 0.03). Among the survivors, surfactant-treated infants required shorter duration of continuous positive airway pressure (CPAP) (3.4 vs 9.6 days; p = 0.04). For survivors with birthweight of > 1000 g, surfactant-treated infants required shorter duration of ventilatory support (intermittent positive pressure ventilation + CPAP) (7.5 vs 18.9 days, p = 0.02). Overall, surfactant-treated infants achieved full enteral feeds sooner (15.7 days vs 24.6 days; p = 0.03) and required shorter duration of total parenteral nutrition (13.9 days vs 25.6 days; p = 0.02). We concluded that surfactant replacement therapy was effective in the treatment of preterm infants with RDS.
A total of 97 children aged 1 month to 16 years (mean 6.6 years) had upper endoscopies performed in Paediatric Institute, Kuala Lumpur Hospital between January 1997 and December 1999 for various gastrointestinal symptoms. Of these 70 children were tested for Helicobacter pylori. The four most common indications for upper endoscopy were recurrent abdominal pain, upper gastrointestinal bleeding, epigastric pain and vomiting. The overall prevalence of this infection in this heterogenous group of symptomatic children was 10% (7/70). This study shows that H.pylori positivity in a routine endoscopy population is low and does not appear to be associated with specific symptoms.
Between February 1990 and May 1993, 13 cases of early congenital syphilis (ECS) were managed in the Paediatrics Unit, University Hospital, Kuala Lumpur. Twelve mothers were unbooked with 10 inborn babies. Only one mother had antenatal booking at this hospital but she defaulted antenatal follow-up. Several risk factors associated with ECS were identified: inadequate or no prenatal care (5/13), failure to repeat a serological test for syphilis in the third trimester when it was tested negative at first booking (5/13), sexual promiscuity, substance abuse and a past history of contracting sexually transmitted disease. All 10 mothers who had their serological test repeated at delivery were found to have a positive VDRL and TPHA. Adequate antenatal care early referral of infected, expectant mothers for treatment, and a repeat serological test for syphilis could have prevented these cases of ECS.
