Orbital myositis in children is uncommon. Recurrence is a major challenge in management. An 11-year-old Malay girl who presented with bilateral orbital myositis with recurrent attacks of diplopia is reported.
The majority of cases of purpura fulminans are associated with Neisseria meningitidis sepsis. However, other bacteria, including Streptococcus pneumoniae, can also be the cause. Underlying predisposing conditions are immunodeficiencies and splenic dysfunction, the latter being the most frequent in the paediatric age group. Purpura fulminans secondary to pneumococcal sepsis in a healthy infant is described.
A 7-year-old boy, referred with lymphoma, presented with prolonged fever and intra-abdominal lymphadenopathy demonstrated on computed tomography (CT) of the abdomen. Blood culture isolated Penicillium marneffei. The patient was subsequently proven serologically to be positive for human immunodeficiency virus (HIV). Treatment with amphotericin B followed by itraconazole was successful. A high level of clinical suspicion and awareness is necessary for early diagnosis of penicilliosis, especially in an era of an increasing prevalence of HIV in this region.
There are few data on paediatric melioidosis in endemic areas outside rural north-eastern Thailand and northern Australia. This study reports 16 culture-confirmed cases of melioidosis in children aged < or = 15 years seen between 1976 and 2005 at an urban teaching hospital in Kuala Lumpur, Malaysia. Seven (43.8%) patients had septicaemic melioidosis (with three known deaths) and nine (56.2%) had localised disease (one death). Eleven (68.8%) patients had underlying diseases, including five with haematological malignancies. Skin, soft tissue and lymph nodes were most commonly affected. There were no cases of parotitis or pharyngocervical disease (seen in Thailand), or encephalomyelitis (seen in Australia). The differences in disease seen in this study compared with the mostly rural patients described in previous studies might be owing to a different patient population in an urban environment. Septicaemic melioidosis has a high mortality, but localised disease has a good prognosis, and selected cases may be cured without the full recommended treatment regimen.
A descriptive study using data from the medical records of 448 children with febrile convulsion was carried out to determine the seizure characteristics and use of anti-convulsant therapy for febrile convulsions in a Malaysian hospital. There was a higher incidence of multiple seizures and a lower incidence of focal seizures in the local population than in studies done among Western populations. The majority of initial seizures occurred within 24 h of fever onset. Transient neurological abnormalities following an acute seizure were common. A quarter of children referred by general practitioners had been given anti-convulsants prior to referral but up to 20% of general practitioners had used ineffective routes for administering diazepam. However, diazepam used in the hospital was found to be effective in controlling acute febrile seizures.
We report a full-term baby boy who presented soon after birth with severe congenital rickets. Maternal and neonatal vitamin D levels were very low and the infant responded well to oral vitamin D. Transient secondary hyperparathyroidism normalised on treatment. The mother's vitamin D deficiency was attributed to the region's cultural dress code which prevents exposure to sunlight. There has not been a previous report of severe congenital rickets from this region.
We describe a 7-year-old child who presented with a soft fluctuant swelling on the neck which became more prominent during the Valsalva manoeuvre. He underwent adeno-tonsillectomy based on a mistaken diagnosis of ballooning of the pharynx secondary to enlarged adenoids and tonsils obstructing the nasopharyngeal and oropharyngeal airways. Investigations revealed the swelling to be a markedly dilated internal jugular vein. We discuss the diagnostic features and mode of treatment of this condition so as to avoid unnecessary and dangerous surgical intervention.
A prospective study was carried out to (i) compare head growth patterns of 103 very low birthweight (VLBW, < 1500 g) Malaysian infants and 98 normal birthweight (NBW, 2500- < 4500 g) controls during the 1st year of life; and (ii) examine the relationship between neurodevelopmental outcome at 1 year of age and occipito-frontal head circumferences (OFC) at birth and at 1 year of age in VLBW babies. When compared with those of NBW infants at birth, mid-infancy and 1 year of age, the mean OFC ratios (observed/expected OFC at 50th percentile) of VLBW infants were significantly lower (p < 0.001). Small-for-gestational-age (SGA) VLBW babies had significantly lower mean OFC ratios than their appropriate-for-gestational-age (AGA) VLBW counterparts at birth (p < 0.001), but this difference was no longer seen at mid-infancy or at 1 year of age. Logistic regression analysis showed that abnormal late neonatal cranial ultrasound findings (odds ratio 8.5, 95% confidence interval 4.12-22.07; p < 0.001) and each additional day of oxygen therapy (odds ratio 1.15, 95% confidence interval 1.00-4.45; p = 0.045) were significant risk factors associated with neurodevelopmental disability at 1 year of age, while mean OFC ratios at birth or at 1 year of age were not. Poor postnatal head growth per se did not predict disability, but probably reflected the consequences of "brain injury" as evidenced by abnormal brain scans.
Extra-intestinal non-typhoidal Salmonella (NTS) infections are uncommon in developed countries but common in developing ones. The risk factors, clinical features and outcome of children admitted to the Department of Paediatrics, University of Malaya Medical Center, Kuala Lumpur from 1978 to 1998 with extra-intestinal NTS infections were reviewed. All positive cultures of NTS, blood, cerebrospinal fluid, urine, synovial, pericardial and other body secretions (except stools), were included. Of the 98 cases reviewed, 56 were boys and 42 girls. The mean age was 2.1 years (range: newborn to 14 years). Twenty-seven children were severely immunocompromised and 21 had underlying chronic medical disorders. Bacteraemia was the most commonly detected type of infection and meningitis the commonest focal infection. The overall mortality rate was 15%. An immunocompromised state or underlying chronic medical disorder was associated with increased mortality. The three serotypes most commonly isolated were S. enteritidis, S. paratyphi B and S. typhimurium. Most isolates were sensitive to antibiotics commonly used in salmonellosis.
We describe a Malay girl with disseminated cryptococcosis affecting the lungs, liver, lymph nodes and bones. The diagnosis was made by culture of the bone marrow. Tests of immune function showed that she was HIV-negative but the CD4 percentage was persistently low. Idiopathic CD4+ T-lymphocytopenia was diagnosed. The child died despite two courses of anti-fungal therapy.
All post-neonatal children with acute non-traumatic coma admitted over an 8-month period were analysed and followed up for 18-24 months to determine the aetiology and outcome of their coma. One hundred and sixteen children, 72 boys and 44 girls, were recruited. Half the children were under 1 year of age and only 16 (14%) were more than 6 years of age. Eighty cases (69%) were due to infection, 15 (13%) to toxic metabolic causes, six (5%) to hypoxic ischaemic insults, four (3.5%) had intracranial haemorrhage, nine (7.8%) were due to miscellaneous causes and in two (1.7%) the cause was unknown. Seven cases were lost to follow-up. Of the remainder, 39 (35.7%) died, 32 (29.3%) developed permanent neurological deficit, and 38 (35%) were discharged well. The outcome was worst in the infectious group. Age of onset and sex did not significantly affect outcome. Our findings are similar to experience in Japan, where infection accounts for 74% of non-traumatic coma, but differ considerably from Western data on childhood coma where only a third of cases are due to infection.
In dengue shock syndrome, an acute increase in capillary permeability results in leakage of plasma into the interstitial space. Pleural effusion is commonly seen in dengue shock syndrome. We report three cases of dengue-associated adult respiratory distress syndrome (ARDS) in children, in all of whom dengue haemorrhagic fever, presenting with grade 3 or grade 4 dengue shock syndrome with disseminated intravascular coagulopathy, was confirmed. The criteria for the diagnosis of ARDS were based on the expanded definition of ARDS by Murray et al. Treatment consisted of fluid resuscitation, correction of coagulopathy and mechanical ventilation. All three children had multi-organ impairment, but it was more severe in the two who died. The one survivor was well at discharge.
A hospital study was carried out to compare parenting stress among 87 Malaysian mothers of children with cerebral palsy and a control group (comprising 87 mothers of children without disability who attended the walk-in paediatric clinic), using the Parenting Stress Index (PSI) questionnaire. Multiple regression analysis was used to determine socio-demographic and medical factors associated with child-domain stress (CDS) and parent-domain stress (PDS). Mothers of children with cerebral palsy scored significantly higher than control subjects on all sub-scales of CDS and PDS (p < 0.01), except for the sub-scale of 'role restriction'. The presence of cerebral palsy (p < 0.001) and activities of daily living (ADL) scores (p < 0.001) were significantly associated with CDS. Factors predictive of PDS were ADL scores (p < 0.001), number of hospitalizations over the past year (p = 0.024), level of maternal education (p = 0.018) and Chinese mothers (p < 0.001). Although this study demonstrated that Malaysian mothers of children with cerebral palsy experienced higher levels of stress than controls, the impact of cerebral palsy per se on parenting stress was modified by other factors such as increased care-giving demands, low maternal education and ethnic background. Habilitation should be directed at easing the burden of daily care, minimizing hospital re-admissions and targeting appropriate psychosocial support at specific subgroups to change parental perception and expectations.

Despite concerns about adverse effects, chloramphenicol (CMC) continues to be used in certain situations and, due to its low therapeutic index and variable pharmacokinetics, therapeutic drug monitoring (TDM) is often recommended. At our centre, CMC finds applications in typhoid and meningitis and TDM is routinely performed. Elsewhere in Malaysia, however, CMC is used without TDM. We therefore decided to evaluate our TDM for CMC in relation to its roles in CMC therapy in children, who constitute most of our patients. Our objective was also to develop strategies to improve our TDM for CMC use. Data were collected from 168 children given CMC for various indications and monitored by the TDM service. Plasma CMC was determined by HPLC and used to adjust doses to maintain concentrations within a range of 10-25 micrograms/ml. Outcomes measured included daily temperatures and haematological indices. Daily doses and plasma CMC varied greatly. Doses averaged 40.5 mg/kg for neonates and 75.5 for older children. Average peak concentrations were therapeutic in 60% and trough in 42%. Average duration of fever was 6.3 days and it was unaffected by plasma CMC. Typhoid was eradicated in 97% but nine children with other diagnoses died. Side-effects were confined to mild reversible haematological abnormalities which developed in 11% of children at plasma concentrations which tended to be high. We conclude that CMC remains useful in children with typhoid. Its use for other indications, however, should be reviewed. Routine TDM for CMC is probably not warranted, at least until a clearer role is defined by well designed prospective studies.
We report a case of meningitis and one of fatal septicaemia in neonates due to Burkholderia pseudomallei and review the literature on neonatal melioidosis. Pneumonia was the primary presentation and was complicated by shock in the latter case. The epidemiological findings suggest that the cases reported from Malaysia were community-acquired in contrast with those from the USA and Thailand.
Tropical pulmonary eosinophilia (TPE) is considered to be a variant of human filarial infection. The pulmonary manifestations of TPE have been well described. Extra-pulmonary features of the disease, although not commonly seen, have been reported previously. A 9-year-old Malay girl with a history of recurrent cough and wheezing was admitted because of cardiac failure. Physical examination revealed a very sick girl with tachypnoea, central cyanosis, finger clubbing, elevated jugular venous pulse, generalized crackles and rhonchi in the chest, a loud second heart sound and hepatosplenomegaly. A chest radiograph showed cardiomegaly and right pleural effusion. Laboratory investigations revealed hypochromic, microcytic anaemia with persistent blood eosinophilia (absolute eosinophil counts varied from 1.9 to 5.5 x 10(9)/1). The ELISA test for antifilarial IgG antibodies was strongly positive. She responded promptly to treatment with diethylcarbamazine. In summary, this is a patient with TPE who presented with cor pulmonale, probably due to late-stage interstitial pulmonary fibrosis. In order to prevent the long term morbidity of cardiorespiratory disability, the early signs of TPE should be recognized and the infection treated.
Haemophilus influenzae type b (Hib) endocarditis is a rare but potentially lethal condition. Only ten cases have been reported in the English literature. This report describes an 8-month-old Malay child with a ventricular septal defect who developed Hib endocarditis and died after 4 weeks of hospitalization. The literature is reviewed and previously reported cases summarized.
We report seven cases of Kawasaki disease (KD) who were admitted to Hospital University Sains Malaysia over a period of 8 years. The average age at the time of admission was 29.4 months and four of the children were boys. Five children had all six criteria for diagnosis. Ileus was present in three, and hydrops of the gall bladder and pneumonia in two each, but coronary artery dilatation was seen in only one patient. We also review all the cases of KD reported so far from Malaysia and compare the epidemiological data, clinical course and laboratory findings of the Malaysian patients with those from other parts of the world. The epidemiological and clinical features of Malaysians with KD differ from those seen in Singapore and Japan, but are similar to those seen in Thailand, Australia and North America. The incidence of cardiac complications is low in Malaysians.
A wide variety of skin disorders in children are encountered by doctors practising in tropical countries. While some of them are common and pose little difficulty in their management, a few are uncommon, run a protracted course and cause errors in diagnosis. Two patients--one with cutaneous tuberculosis and the other with chromomycosis--are described and illustrate the importance of early and prompt detection of disease in children.
In a case control study, 70 children consecutively hospitalized for acute ingestion of poisons were compared with 140 other hospitalized children matched for age. Children aged less than 3 years and boys were most often the victims. Univariate analysis identified Indian race, having a parent younger than 21 years, residing at present address for less than 1 year and living in a household with more than five occupants as significant risk factors. Experience of a recent stressful event in the family barely failed to reach the level of significance. Logistic regression analysis confirmed that Indian race, having a parent younger than 21 years and residing less than 1 year at the present address were independent predictors of acute poisoning. Positive interactions were noted between Indian race and duration of residence and between parental age and duration of residence. Knowledge of risk factors and their interactions may be useful in planning preventive measures against childhood poisoning.
