    PMID: 1627057
    Large ovarian cysts in the fetus are uncommon. Ultrasonography has helped in the detection of these cysts antenatally and in the newborn female infant. A case of bilateral ovarian cysts in a newborn is presented. The choice of management between conservative measures and surgical approaches remains controversial.

    Most muscular dystrophies manifest as peripheral muscular weakness commencing at various age, however, oculopharyngeal muscular dystrophy (OPMD) is a rare hereditary disorder presenting in middle age with progressive dysphagia and bilateral blepharoptosis rather than peripheral muscular weakness. In the medical literature, OPMD has been well described in Canadians of French descent. So far, there is no publication of OPMD in the Malaysia-Singapore medical literature. This article documents this condition in a Chinese patient. A review of the literature is presented and the management of OPMD is discussed.

    Australas Radiol, 1992 May;36(2):158-9.
    PMID: 1520180
    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.
  4. Depressed skull fracture in a newborn successfully managed conservatively: a case report
    Lim CT, Koh MT, Sivanesaratnam V
    Asia Oceania J Obstet Gynaecol, 1991 Sep;17(3):227-9.
    PMID: 1953432
    A preterm baby was born to a multiparous mother by emergency caesarean section at 36 weeks of gestation. Apart from a depression on the right temporo-parietal region measuring 3 cm x 3 cm x 0.5 cm, no other abnormality was noted. A CT scan of the brain excluded the presence of intracranial haematoma and pressure effect on the brain. Spontaneous reduction of the fracture without any adverse neurological sequelae suggests that these fractures can be managed conservatively in some instances.

    PMID: 8009287
    Meconium ileus, rare in Malaysia, accounts for 3.7% of all neonatal intestinal obstructions (excluding imperforate anus) seen in the University Hospital, Kuala Lumpur, from 1980-1990. This paper retrospectively reviews our clinical experience with 5 cases of meconium ileus seen over a 12-year period from 1980-1991 in the University Hospital, Kuala Lumpur. Three of the neonates were Malays, and two were Punjabis. Four of them were full-term and one preterm. The birth weights ranged from 1900 to 3700 g, with a mean of 2670 g. One of them also had a sibling with meconium ileus. Two of them were found to have foetal ascites and one had intestinal obstruction, antenatally by ultrasonography. The remaining two were symptomatic soon after birth. Extensive calcification was observed on plain abdominal radiographs in three babies and dilated bowels in the other two. All of them underwent laparotomy and uncomplicated meconium ileus was confirmed in two cases, meconium peritonitis in two and one meconium pseudocyst in addition to meconium peritonitis. There was one intraoperative death, and one long-term survivor who did not have cystic fibrosis. The remaining three did not have additional features suggestive of cystic fibrosis, and finally succumbed to respiratory infection. Sweat test was not done to confirm the diagnosis for logistic reasons. The management of such patients proved to be a challenge to clinicians because of the rarity of this condition.
  7. Fulltext Neonatal meningitis due to non-encapsulated Haemophilus influenzae in a set of twins--a case report
    Lim CT, Parasakthi N, Puthucheary SD
    Singapore Med J, 1994 Feb;35(1):104-5.
    PMID: 8009266
    A set of twins born to a 24-year-old primigravida had evidence of sepsis 24 to 60 hours after birth and were treated empirically with penicillin and gentamicin. A non-encapsulated H. influenzae biotype IV strain was isolated from the blood cultures of both and from the CSF of twin II. The isolates were beta-lactamase positive and hence showed resistance to ampicillin and therapy was changed to chloramphenicol only. Twin II recovered but Twin I developed a brain abscess in the left occipital region which resolved with extended antibiotic treatment. Although ampicillin-resistant H. influenzae have been reported in Malaysia, invasive disease by such strains are rare.
  8. Fulltext Severe metabolic changes following oral sodium phosphate in a patient of renal cell carcinoma - On dialysis
    Lim CT
    Indian J Pharmacol, 2016 May-Jun;48(3):327-8.
    PMID: 27298508 DOI: 10.4103/0253-7613.182875
    Oral sodium phosphate (OSP), an effective bowel purgative, is available over the counter (OTC) and requires a substantially lower volume than polyethylene glycol-based preparative agents. Rarely, OSP consumption has been associated with acute hypocalcemia and hyperphosphatemia. We describe a case of chronic kidney disease patient developing symptomatic hypocalcemia following OTC OSP.
  9. Novel PAX4 variant in a child and family with diabetes mellitus - case report and review of the literature
    Lee YL, Ting TH, Lim CT, Arrumugam-Arthini C, Karuppiah T, Ling KH
    J Pediatr Endocrinol Metab, 2023 Oct 26;36(10):988-992.
    PMID: 37621150 DOI: 10.1515/jpem-2023-0171
    OBJECTIVES: PAX4 (Paired box 4), a transcription factor crucial in pancreatic beta cell development and function, is a rare cause of maturity-onset diabetes of the young (MODY). What is new? A novel PAX4 variant is verified by family segregation study to be likely pathogenic. A child below 10 years of age diagnosed to have PAX4-MODY, differing from previously reported paediatric cases diagnosed in adolescence.

    CASE PRESENTATION: A child with diabetes diagnosed at age 8 years, harbored a PAX4 variant, c.890G>A (p.Gly297Asp), initially classified as variant of uncertain significance. Eleven family members (7 adults and 4 children) with and without diabetes across 3 generations were genotyped. The variant co-segregated with diabetes or prediabetes across 3 generations of the family. The variant is reclassified as likely pathogenic according to standard guidelines.

    CONCLUSIONS: Genetic testing is essential to confirm PAX4-MODY as the presentation is variable even within the same family. PAX4 mutation needs to be considered in MODY genetic testing in Asian patients.

  10. Identification of a Novel IGSF1 Variant in Two Malaysian Male Siblings with Central Hypothyroidism and Macroorchidism
    Lee YL, Ting TH, Lim CT, Thilakavathy K, Musa NH, Ling KH
    J Clin Res Pediatr Endocrinol, 2024 Apr 22.
    PMID: 38647408 DOI: 10.4274/jcrpe.galenos.2024.2023-12-1
    IGSF1 mutation is the commonest cause of mild to moderate isolated central congenital hypothyroidism and has an X-linked recessive inheritance, primarily affecting males. Other notable clinical features are macroorchidism with delayed pubertal testosterone rise, large birth weight, increased body mass index, low prolactin, transient growth hormone deficiency and low prolactin. Two male siblings with central hypothyroidism were found to have a novel IGSF1 c.3467T>A variant that was likely pathogenic based on the family segregation study. The proband, aged 3 years presented at 18 days old with prolonged jaundice while his 16-year-old brother was only detected to have central hypothyroidism after the proband's genetic analysis result was known. Both siblings were obese, had large birth weights, macroorchidism and low prolactin. The proband's brother had intellectual disability while the proband had normal development. This case study highlights the importance of evaluation for the IGSF1 variant in patients with unexplained central hypothyroidism, especially when accompanied by X-linked inheritance and macroorchidism. Family segregation analysis allows detection of other affected family members or carriers who may also benefit from thyroxine treatment.
  11. Fulltext Early congenital syphilis: experience with 13 consecutive cases seen at the University Hospital, Kuala Lumpur
    Koh MT, Lim CT
    Singapore Med J, 1991 Aug;32(4):230-2.
    PMID: 1775999
    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.

    Koay AC, Choo MM, Nathan AM, Omar A, Lim CT
    J Ocul Pharmacol Ther, 2011 Jun;27(3):309-11.
    PMID: 21542771 DOI: 10.1089/jop.2011.0013
    The purpose of this report was to describe 2 cases of periocular infantile hemangiomas (IHs) that were successfully treated with low-dose oral propranolol alone and in combination with oral prednisolone.
  13. Fulltext Characteristics of Malaysian infants with biliary atresia and neonatal hepatitis
    Karnameedi S, Lim CT
    Med J Malaysia, 1997 Dec;52(4):342-7.
    PMID: 10968111
    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.

    Med J Malaysia, 2023 Jan;78(1):1-6.
    PMID: 36715183
    INTRODUCTION: Tuberculosis (TB) in Malaysia has estimated incidence and mortality rates of 81 cases per 100,000 people-year and 4.9 per 100,000 populations, respectively. This study aimed to study the characteristics of rural TB patients and their mortality outcomes.

    MATERIALS AND METHODS: This is a retrospective observational study involving real-world data analysis, looking into TB patients in Lubok Antu Health Clinic by obtaining data through clinic cards, from 1 January 2019 till 31 December 2020. Statistical significance was p < 0.05.

    RESULTS: Eighty-four patients were included. Fifty-two (61.9%) were male. Median age was 58.5 (39-67). Forty-six (54.8%) had smear-positive TB. Seventy-eight (92.9%) were alive at treatment completion. Fifteen (17.9%) experienced adverse drug reactions. Estimated prevalence and mortality rate were 7.1% and 10.7 per 100,000 populations, respectively. Regression analyses revealed that drug reaction was significantly associated with compliance [OR = 8.38 (95% CI: 1.26, 55.53), p = 0.029]. Patients compliant with treatment were more likely to survive [OR = 12.5 (95% CI: 1.61, 97.34), p = 0.028].

    CONCLUSION: Compliance with TB treatment should be emphasised to reduce TB-related mortality.

    PMID: 38031215
    INTRODUCTION: Despite recent advancements in the diagnosis and management of infective endocarditis (IE), it is associated with substantial morbidity and mortality. Our study objective is to determine the factors associated with in-hospital mortality in IE patients among the local population.

    MATERIALS AND METHODS: All IE patients who were diagnosed with definite or possible IE and were treated at Sarawak Heart Centre from 1st January 2020 to 31st December 2022 were recruited. We examined the demographic features of the subjects and the factors that contributed to in-hospital mortality. Multivariate logistic regression was used to analyse the associated factors and in-hospital mortality.

    RESULTS: Our study population comprised a total of 37 patients with a mean age of 46.4 years and male predominance. The in-hospital mortality rate of IE in this study was 44.4%. Haemodynamic instability and anaemia were found to be strong predictors of IE survival outcome, with an odds ratio of 51.5 and 35.7 respectively. Patients with vascular phenomenon and heart failure were at 10.5- and 6.0-times higher odds of dying, however, these two associations were found to be not statistically significant.

    CONCLUSION: The in-hospital mortality due to IE in our study was among the highest in developing countries. Factors of hypotension and optimal response to individual hemodynamic parameters may confer lower mortality. While anaemia is demonstrable as a risk factor for inpatient mortality, a target has yet to be reasonably established.

    PMID: 10497665
    This study aims to determine the prevalence of and risk factors associated with retinopathy of prematurity (ROP) in very low birth weight (VLBW) infants. All premature VLBW infants, admitted into the neonatal intensive care unit of the University Hospital Kuala Lumpur, were screened from 4 weeks of life. Perinatal and neonatal data were retrieved from the infants' medical notes. Between August 1994 and July 1996, 100 infants had their eyes examined serially. Of the 15 (15%) infants with ROP, all were less than 31 weeks gestation, and only 1 infant had birth weight above 1250 g. Five (5%) infants had severe ROP; 4 infants underwent cryotherapy for stage 3 threshold disease. Infants with ROP, as compared to infants without ROP, had lower birth weight [mean (SEM) 993 (50) g versus 1205 (22) g, P < 0.001], lower gestational age [mean (SEM) 28.0 (0.4) weeks versus 30.1 (0.2) weeks, P < 0.001], higher rates of patent ductus arteriosus and chronic lung disease, greater number of radiographic examinations and episodes of late-onset suspected/confirmed sepsis, and required longer duration of supplemental oxygen, ventilation, xanthine, antibiotics and intralipid use, but were slower to establish full enteral feeds. On multivariate logistic regression analysis, birth weight < or = 1000 g [OR 2.38, 95% CI 1.25, 4.55, P = 0.009] and gestational age < or = 28 weeks [OR 2.86, 95% CI 1.47, 5.56, P = 0.002] were significant predictors of increased risk of this disease. In conclusion, ROP is strongly associated with smaller, more immature and sicker neonates. Prevention of prematurity would help reduce the incidence of this disease.

    Chye JK, Lim CT, Van der Heuvel M
    Pediatr Surg Int, 1997 Apr;12(4):296-8.
    PMID: 9099650
    Three cases of neonatal chylous ascites (CCA) were managed in the neonatal unit, University Hospital, Kuala Lumpur, over the past 9 years. Fetal ascites and polyhydramnios were the sole abnormalities detected in all three babies by antenatal ultrasonography. They were born at 36 weeks' gestation and their birth weights ranged from 3.0 kg to 3.8 kg. All three infants had abdominal distension at birth. Milky ascitic fluid was obtained after starting enteral feedings. Analysis of the ascitic fluid revealed a raised white blood cell count (predominantly lymphocytic) and triglycerides (1.4 - 3.8 mmol/l), cholesterol (1.6 - 2.8 mmol/l), and protein levels (25 - 41 g/l). Conservative management with skimmed milk and medium-chain triglycerides in one infant and Pregestimil in another was instituted. these two infants with CCA were clinically normal when reviewed at 19 months and 3.5 years of age. The third infant had a gut malrotation and associated pyloric septum; he died from complications of a laparotomy. The literature on this rare condition is reviewed.

    PMID: 9431381
    Dengue, an important mosquito-borne flavivirus infection, is endemic in Southeast Asia. We describe two mothers who had acute dengue 4 and 8 days before the births of their infants. One mother had worsening of her proteinuric pregnancy-induced hypertension, liver dysfunction, and coagulopathy and required multiple transfusions of whole blood, platelets, and fresh frozen plasma. Her male infant was ill at birth, developed respiratory distress and a large uncontrollable left intracerebral hemorrhage, and died of multiorgan failure on day 6 of life. Dengue virus type 2 was isolated from the infant's blood, and IgM antibody specific to dengue virus was detected in the mother's blood. The second mother had a milder clinical course; she gave birth to a female infant who was thrombocytopenic at birth and had an uneventful hospitalization. Dengue virus type 2 was recovered from the mother's blood, and IgM antibody specific to dengue virus was detected in the infant's blood. This report highlights not only the apparently rare occurrence of vertical transmission of dengue virus in humans but also the potential risk of death for infected neonates.
  19. Breastfeeding at 6 weeks and predictive factors
    Chye JK, Zain Z, Lim WL, Lim CT
    J Trop Pediatr, 1997 10;43(5):287-92.
    PMID: 9364127 DOI: 10.1093/tropej/43.5.287
    Despite the numerous changes made in accordance with the Baby Friendly Hospital Initiative at the University Hospital, Kuala Lumpur, the low rates of breastfeeding have persisted. This study aims to examine the current trend in infant feeding, and the influences of some perinatal and sociodemographic factors on breastfeeding. Five-hundred mothers with singleton pregnancies and healthy infants were interviewed at 6 weeks post-partum. Only 124 (25 per cent) mothers were practising exclusive breastfeeding (EBF), and 132 (26 per cent) mothers were using exclusive infant formula feeding (EIF). On logistic regression analyses, mothers who followed EBF were more likely to have had antenatal plans to breastfeed (Odds ratio 2.44, 95 per cent confidence interval 1.75-3.45), not in paid employment post-natally (OR 1.76, 95 per cent CI 1.31-2.36), of older age group (> 27 years) (OR 1.48, 95 per cent CI 1.13-1.93), had female infants (OR 1.38, 95 per cent CI 1.05-1.80) and of Indian ethnicity (compared to Chinese) (OR 3.87, 95 per cent CI 2.16-6.89). Breastfeeding difficulties were associated with decreased odds of EBF (OR 0.21, 95 per cent CI 0.13-0.34). Parental education, fathers' ages and incomes, primigravida status, Caesarean section, present of episiotomy, late first breastfeed, phototherapy, and length of hospital stay were not significant predictors of failure of EBF. In comparison, predictive factors for increased use of EIF were mothers who have had breastfeeding difficulties, < or = 9 years of schooling, and of Chinese descent. In conclusions, the overall rate of EBF by 6 weeks of age in infants born in this urban hospital had remained poor. The adverse factors for EBF identified in this study warrant further in-depth studies to determine effective ways of improving EBF rates.
