    Neck masses in infants and children have a wide differential diagnosis. However, neck masses apparent only during raised intrathoracic pressure are rare with a limited number of causes, including superior herniation of the normal thymus, apical lung herniation, jugular phlebectasia and laryngocoele. These conditions can easily be differentiated from one another by imaging. We present an infant with intermittent suprasternal neck mass visible only during increased intrathoracic pressure, produced either by crying or straining. Diagnosis of superior herniation of the thymus into the neck was confirmed by ultrasonography with the characteristic sonographic appearances of the normal thymus as well as its shape, size and location. Ultrasonography should be the first imaging modality of choice. Management of superior herniation of the thymus into the neck should be conservative as the thymus naturally involutes with increasing age. Awareness of the differential diagnosis of neck swelling present only on Vasalva manoeuvre or increased intrathoracic pressure is important to prevent unnecessary tests, avoid radiation, biopsy and surgery.

    AIM: This study aimed to determine which factors could influence (i) parents' decision to seek medical consultatin and (ii) their preference for either public or private medical service in children with upper respiratory tract infection.
    METHODS: This cross-sectional study was conducted at the Gombak district, which is an urban area in Malaysia. We randomly selected parents of kindergarten children aged 4-5 years to participate in this questionnaire survey. The main outcome measures were predictors of early medical consultation and type of service utilisation (public versus private).
    RESULTS: We achieved a response rate of 84.5% (n = 1033/1223). 64.1% sought early medical consultation and 70.9% preferred to consult a private doctor. Early consultation was predicated by the parent gender being male (OR 1.50; 95% CI 1.09, 2.05), non-Chinese (OR 1.75%; 95% CI 1.10, 2.79), and those who preferred child specialists (OR 2.02; 95% CI 1.27, 3.23). Lower income group (OR 4.28; 95% CI 2.30, 7.95) and not having a regular doctor (OR 4.99%; 95% CI 3.19, 7.80) were predictors of using the public health services.
    CONCLUSIONS: Parent's gender, ethnicity and income influenced their decision to seek early medical consultation for their children's respiratory illness while income and having a regular doctor could predict their choice of healthcare services.

    A 12-year old girl presented with an unusual problem of recurrent discharging multiple skin sinuses on her right anterior and posterior chest wall for a year. There was ipsilateral lower lobe pneumonia and imaging showed multiple abscesses in her lower back muscles bilaterally. A purulent fluid was aspirated from her back muscles and the histology examination showed sulphur granules with gram positive branched filaments. She responded well to the treatment for actinomycosis with penicillin and doxycycline.

    Empirical therapy for children with febrile neutropenia has traditionally consisted of combination antibiotics, usually a beta-lactam and an aminoglycoside. However, recent trends and international guidelines have now made monotherapy a feasible option in the management of this group of patients. We prospectively evaluated the efficacy and safety of cefepime monotherapy in our population of paediatric cancer patients with febrile neutropenia.

    AIM: Fever in children, a mostly benign and self-limiting illness, is often viewed with consternation by the care givers. It results in early consultation and excessive use of antipyretics and antibiotics. In this study, we document the prescribing practice of doctors from three primary care settings in Malaysia and identify the predictors of antibiotic prescription.
    METHODS: Interview of care givers bringing febrile children (age = 12 years) to three primary care settings: public primary care clinics, private general practice clinics and a university-based primary care clinic.
    RESULTS: Data from 649 children were analysed. Mean age of children 4.1 years and 55% were boys. One-third of the children had prior consultation for the same episode of fever. About 80% of the febrile children were diagnosed to have upper respiratory tract infection, viral fever and gastroenteritis. Overall antibiotic prescribing rate was 36.6% (public primary care clinic 26.8%, private general practice clinic 70.0% and university-based primary care clinic 32.2%). Independent predictors of antibiotic prescription were: clinic setting, longer duration of fever (>7 days), higher temperature (>38 degrees C) and the diagnosis of upper respiratory tract infections. After controlling for demographic and clinical factors, antibiotic prescription in private general practice clinic was seven times higher than public primary care clinic (odds ratio 7.1, 95% confidence interval 4.0-12.7), and 1.6 times higher than university-based primary care clinic (odds ratio 1.6, 95% confidence interval 1.0-2.5).
    CONCLUSION: Differences in the patients' demographic and clinical characteristics could not adequately explain the high antibiotic prescribing rate in private general practice clinics. This inappropriately high antibiotic prescribing for febrile children in private general practice clinics is a suitable target for future intervention.

    A 5-year-old Chinese girl with 1-year history of progressive jaundice, steatorrhoea and pruritus was referred. Physical examination showed failure to thrive, marked jaundice, finger clubbing and hepatomegaly. There was laboratory evidence of cholestatic jaundice and autoimmunity, with marked elevation of alkaline phosphatase (ALP) and gamma-glutamyl transferase (gammaGT). Histology of percutaneous liver biopsy revealed hepatitis around the portal triad, as well as features of liver cirrhosis. Primary sclerosing cholangitis (PSC) overlapping with autoimmune hepatitis (AIH) was suspected. Endoscopic retrograde cholangiopancreatography (ERCP) was not feasible as there was no weight-appropriate ERCP scope available. Magnetic resonance cholangiopancreatography (MRCP) was performed and revealed areas of irregularity and slight attenuation of the right and left hepatic ducts, representing stricturing, in keeping with PSC. PSC/AIH overlap syndrome was diagnosed in this child in which MRCP has contributed to its diagnosis.

    OBJECTIVES: To estimate the risks of seroconversion of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency viruses (HIV) in children with multitransfused thalassaemia at a thalassaemic clinic in Kuala Lumpur, Malaysia.
    METHODS: Seventy-two children (39 males, median age 11.3 years, 2.5th-97.5th centile: 1.4-19.2 years) with thalassaemia major were studied. The risks of seroconversion of HBV, HCV and HIV were estimated by comparing the seroprevalences of hepatitis B surface antigen (HBsAg), anti-HCV and anti-HIV between a defined starting point and an end point. The end point was the point when latest serological results were available while the starting point was when regular transfusion was commenced, or approximately 5 years before the end point when the duration of transfusion was longer.
    RESULTS: The median duration of the study was 49 months (range 8-69 months, total 2953 patient-months). There were 2605 transfusion episodes and 4154 units of blood transfused (0.88 transfusion episode/patient per month, 1.41 units of blood transfused/patient per month). There were three new seroconversions for anti-HCV but none for HBsAg and anti-HIV. The risk of seroconversion for HCV was one in 1384 units of blood transfused (95% CI: 4000-472). The seroprevalence rates at the starting and end points were: HBsAg (1%, 1%), anti-HCV (10%, 13%) and anti-HIV (0%, 0%), respectively.
    CONCLUSIONS: The estimated risk of acquiring HCV infection in children receiving multiple blood transfusions in this study is surprisingly higher than the generally accepted estimated risk. Other routes of transmission may be important. A prospective, multicentre study to estimate such risks more precisely is needed.

    OBJECTIVES: To determine the pattern of renal histology, clinical outcome of children with lupus nephritis and to identify any associated risk factors predicting renal failure in these children.
    METHODS: Retrospectively, 27 children under 16 years of age with lupus nephritis who had renal biopsies done at Sultanah Aminah Hospital Johor, Malaysia from 1994 to 2002 were studied. The renal histology was graded according to WHO classification system (1982). The medical records, laboratory data and the clinical outcome of the patients were studied.
    RESULTS: There were 24 cases of WHO Class IV, two cases of WHO Class II and a case of WHO Class V. Twenty children were in the good renal outcome group while six children progressed into the poor renal outcome group and required renal replacement. One child was lost to follow-up. All six children in the poor renal outcome group had WHO Class IV histology. The 5-year patient and renal survival rates were 84% and 75%, respectively. Age, sex, activity and chronicity indices in the renal histology, anaemia, elevated serum creatinine, depressed levels of C3 and C4, heavy proteinuria or presence of urinary active sediments were not associated with progression to renal failure.
    CONCLUSIONS: Presently, children with lupus nephritis appeared to have better patient and renal survival rates. Assessment of renal histology in these children was important for diagnosis, treatment and probably prognosis. In this study, there was a 25% incidence of loss of renal function over 5 years in children with WHO Class IV renal histology.
