The purpose of this paper is to demonstrate the effectiveness of using TelePrimary Care (TPC) to monitor immunization programmed in a clinic. Japanese Encephalitis (JE) vaccination was selected as an example because
its coverage has not been satisfactory when compared to that of other vaccinations, which generally exceed 90%.Data for all children who were eligible for JE vaccination (age range from 9 months to 30 months) who attended Sarikei Health Clinic between 1 January
2007 till 31 June 2008, was extracted from the TPC database and analyzed for completeness and timeliness of JE vaccination.The analysis showed that although 1,243 children were eligible to receive their first dose of J vaccine at 9 months of age, only 560 (45%) received it. 15
(3%) received on time, and 545 (97%) received it late (age range from 10 months to 20 months). Out of the 560 who were scheduled to receive their second dose of JE vaccine four weeks after the first, 382 (88%) received it on
time, and 55 (12%) received it late. Only 78 (18%) out of 429 children aged between 18 months to 24 months received their booster dose; 52 (67%) received it on time and 26 (33%) received it late.TPC not only enables health
staff to monitor immunization coverage and timeliness accurately, but it also helps them to identify defaulters quickly so that these children can be traced
and immunized. Doing these tasks manually is time-consuming and tedious, leading to delays in tracing defaulters.TPC provides an effective system for staff to easily access real time child health data to monitor and audit their immunization programme and take remedial action where necessary.

2.Recurrent abdominal pain in childhood.

Recurrent abdominal pain in childhood is common, and continues to be a diagnostic and therapeutic challenge. It is usually attributed to a functional gastrointestinal disorder rather than an organic disease. In most cases, a comprehensive history and physical examination should enable one to make a positive diagnosis of functional disorder. The presence of alarm symptoms and signs, such as weight loss, gastrointestinal bleeding and chronic severe diarrhoea, warrants further investigations and referral to a paediatric gastrointestinal specialist. The mainstay of therapy in functional abdominal pain is education, reassurance and avoidance of triggering factors. While symptom-based pharmacological therapy may be helpful in patients who do not respond to simple management, it is best used on a time-limited basis due to the lack of good evidence of its efficacy. The primary goal of therapy is a return to normal daily activities rather than complete elimination of pain. In recalcitrant cases, psychological interventions such as cognitive behaviour therapy and relaxation training have proven to be efficacious.

Picky eating is a common cause of concern for parents of young children. Paediatricians and family physicians are in a key position to help parents learn ways to feed their children effectively. Despite the high prevalence of picky eating, the growth of the majority of picky eaters does not suffer adversely. In the absence of worrying signs and symptoms, reassurance of the child's normal growth would help allay parental anxieties. Reinforcement of basic feeding principles and providing healthy dietary advice are important strategies to help parents manage children who are picky eaters.

5.Reference range for ADAMTS13 antigen, activity and anti-ADAMTS13 antibody in the healthy adult Singapore population.

INTRODUCTION:
ADAMTS13 (a disintegrin-like and metalloproteinase with a thrombospondin Type 1 motif, member 13) plays a fundamental role in the regulation of haemostasis and thrombosis. Its deficiency leads to an accumulation of ultra-large von Willebrand multimers, inducing spontaneous platelet aggregation, thrombosis in the microvasculature, and thrombotic thrombocytopenic purpura (TTP), a condition with 90% mortality when left untreated. Prompt quantification of ADAMTS13 antigen, activity and autoantibody plays a crucial role in the diagnosis and management of TTP and can help differentiate it from other thrombotic microangiopathies (TMAs). Reference ranges for ADAMTS13 are generally derived from Caucasian patients. Given that polymorphism in the ADAMTS13 gene can be associated with variable ADAMTS13 levels, we aimed to establish the first reference range in Singapore and provide a crucial laboratory test for institutions here and elsewhere.
METHODS:
150 healthy voluntary donors (75 men, 75 women) aged 21-60 years, with an ethnic mix mirroring Singapore's population profile, were recruited. ADAMTS13 antigen, activity and autoantibody levels were measured using the fluorescence resonance energy transfer-vWF73 and enzyme-linked immunosorbent assay methodologies.
RESULTS:
Levels (activity 0.65-1.79 IU/mL, antigen 0.36-1.17 IU/mL, autoantibody 1.4-12.5 U/mL) were not statistically different between the genders and various age groups.
CONCLUSION
TTP and TMAs are encountered in a wide range of specialties. The availability of new assays in Singapore will aid clinicians in the timely management of these conditions. Standardising reference ranges established for Singapore against World Health Organization standards allows harmonisation of measurements between laboratories and for future research collaborations.

Purpose:
The present international survey among healthcare providers aimed to collect data on theoretical knowledge and clinical practices in the diagnosis and management of cow’s milk protein allergy (CMPA) and lactose intolerance (LI) in infants.
Methods:
A global survey was conducted in several countries with diverse health care settings. The survey consisted of multiple-choice questions in 3 main domains: (1) understanding and clinical practices around CMPA and LI; (2) case scenarios; and (3) diseasespecific knowledge and potential educational needs.
Results:
Responses were available from 1,663 participants. About 62% of respondents were general practitioners or general pediatricians, and the remainder were pediatric allergists/ gastroenterologists (18%) or other health practitioners (20%). The survey identified knowledge gaps regarding the types of CMPA (IgE-mediated vs. non-IgE-mediated) and the clinical overlap with LI. The survey suggested diverse clinical practices regarding the use of hypoallergenic formulas, as well as misconceptions about the prebiotic benefits of lactose in extensively hydrolyzed formulas in non-breastfed infants with CMPA. Responses to the two case scenarios highlighted varying levels of awareness of the relevant clinical practice guidelines. While respondents generally felt confident in managing infants with CMPA and LI, about 80% expressed an interest for further training in this area.
Conclusion
The current survey identified some knowledge gaps and regional differences in the management of infants with CMPA or LI. Local educational activities among general and pediatric healthcare providers may increase the awareness of clinical practice guidelines for the diagnosis and treatment of both conditions and help improve clinical outcomes.
7.Prolonged hepatitis and jaundice: a rare complication of paediatric Epstein-Barr virus infection.

We herein report the case of a 14-year-old girl with Epstein-Barr virus (EBV) infectious mononucleosis who developed prolonged hepatitis and jaundice. At presentation, she had tender hepatomegaly with a markedly deranged liver function test. Abdominal ultrasonography showed hepatomegaly and a thickened gallbladder wall. During the subsequent 11 weeks, her transaminases showed two further peaks, which corresponded with clinical deterioration. Her highest alanine transaminase level was 1,795 µ/L and total bilirubin level was 154 µmol/L. She recovered fully with conservative management. EBV-related liver involvement is typically mild and self-limiting. We believe that tender hepatomegaly and gallbladder thickening may be important predictors of significant liver involvement. Although multiple transaminase peaks may occur, we do not consider this an indication for antiviral or immunosuppressive therapy. In the absence of strong evidence supporting the use of any specific therapy, we recommend a conservative approach for an immunocompetent patient.
