Fulltext The prevalence of hepatitis B surface antigen and anti-HCV antibody in paediatric oncology patients in Hospital Universiti Sains Malaysia

Menon BS, Aiyar S

Med J Malaysia, 1997 Dec;52(4):331-4.

PMID: 10968109

This study examined the prevalence of hepatitis B and C markers in 55 paediatric oncology patients who had completed treatment at the Hospital Universiti Sains Malaysia in Kota Baru. All these children had received blood products and had been treated between 1985-1996. Forty seven per cent of patients were positive for hepatitis B or C. Twenty nine per cent were positive for hepatitis C and twenty two per cent were HBsAg positive. Two children were positive for both and none were HIV positive. Four children had an elevated ALT level and one child had jaundice and hepatomegaly. Some children were marker-positive despite immunization and screening of blood.

A prospective study of ocular manifestations in childhood acute leukaemia

Reddy SC, Menon BS

Acta Ophthalmol Scand, 1998 Dec;76(6):700-3.

PMID: 9881556

PURPOSE: To determine the prevalence of ocular manifestations in childhood acute leukaemia at the time of presentation.

METHODS: Eighty-two children with acute leukaemia were examined for ocular lesions within two days of diagnosis before starting chemotherapy. The detailed ocular examination of both eyes was carried out by the ophthalmologist irrespective of the presence or absence of eye symptoms in all cases.

RESULTS: Only 3 out of 82 children presented with eye symptoms (3.6%). However, ocular changes were found in 14 children (17%); ten with lymphoblastic and four with myeloid leukaemia. The ocular lesions observed were proptosis, intraretinal haemorrhages, white centered haemorrhages, cotton wool spots, macular haemorrhage, subhyaloid haemorrhage, vitreous haemorrhage, papilloedema, cortical blindness, sixth nerve palsy, and exudative retinal detachment with choroidal infiltration.

CONCLUSION: In view of the high prevalence of asymptomatic ocular lesions in childhood acute leukaemia, routine ophthalmic examination should be included as a part of evaluation at the time of diagnosis.

Menon BS, Dasgupta A, Jackson N

Pediatr Hematol Oncol, 1998 Mar-Apr;15(2):175-8.

PMID: 9592844

This study reviewed the immunophenotyping results of children with acute leukemia in Kelantan, Malaysia. In the 3.5-year period (January 1994 to June 1997), 45 cases were identified. All children were under the age of 12 years and the predominant ethnic group was Malay. Thirty-six cases (80%) were acute lymphoblastic leukemia (ALL) and 9 cases (20%) were acute myeloblastic leukemia (AML). Of the ALL cases, 3% were of B-cell and 22% of T-cell origin, and 96% of the B-lineage ALL were CD10 positive. All the AML cases expressed CD33 and 78% were positive for CD13. The incidence of mixed-lineage leukemias was 13.8% for My+ ALL and 11.1% for Ly+ AML.

Med J Malaysia, 2005 Dec;60(5):563-9.

PMID: 16515106

To determine the immunisation status of hospitalised infants and to examine the potential risk factors associated with incomplete immunisation. Prospective study of infants admitted to a paediatric hospital in Kuala Lumpur, conducted by interviewing carers. Twenty-two percent of infants had incomplete immunisation. The most significant factor that was associated with incomplete immunisation was the carer's lack of knowledge on the timing of the next immunisation (p = 0.005). Other factors that had significant association were the presence of a previous admission to hospital (p = 0.03) and the infant's age of more than 6 months (p = 0.025). The rate of incomplete immunisation in the study population was 22%. An admission to hospital of an infant should be taken as an opportunity to update their immunisation in order to improve the rate of uptake.

J Trop Pediatr, 1999 Aug;45(4):241-2.

PMID: 10467838

In this prospective study, we examined stool specimens from children with cancer receiving chemotherapy who were admitted for fever to the Universiti Sains Malaysia Hospital in Kota Baru, Kelantan. Stool specimens were examined for ova and cysts of parasites. Over a period of 15 months, there were 129 febrile episodes in 50 children with cancer and, in all, 237 stool specimens were examined. Sixty-six per cent of febrile episodes were associated with neutropenia and 9 per cent were associated with diarrhoea. Stool parasites were found in 42 per cent of children. The most common were helminths, followed by protozoa. Trichuris trichiura was the most common parasite (24 per cent), followed by Ascaris lumbricoides (22 per cent). Hookworm was found in 2 per cent. Giardia lamblia was found in 6 per cent of children, Blastocystis hominis in 4 per cent, and Cryptosporidium parvum in 2 per cent.

Ocular involvement in leukemia--a study of 288 cases

Reddy SC, Jackson N, Menon BS

Ophthalmologica, 2003 Nov-Dec;217(6):441-5.

PMID: 14573980

Two hundred and eighty-eight newly diagnosed cases of leukemia (164 males and 124 females, 167 adults and 121 children, 245 acute and 43 chronic, 151 myeloid and 137 lymphoid), aged between 6 weeks and 78 years, were examined for eye changes in the oncology wards within 2 days of diagnosis before starting chemotherapy. Ocular lesions were present in 102 patients (35.4%)--retinal vascular changes in 91 (31.6%); infiltration of ocular tissues in 5 (1.7%), and neuro-ophthalmic signs in 6 (2.1%) cases. Some of the patients had more than one ocular lesion in one or both eyes. The eye changes were seen more often in adults (49.1%) than in children (16.5%), and in myeloid leukemia (41.0%) than in lymphoid leukemia (29.2%). Eye symptoms were present in 29 patients (10%) at initial diagnosis. Since ocular lesions were detected in many asymptomatic leukemia patients, eye examination should be included as a part of routine evaluation at initial diagnosis in these patients.

Othman IS, Ibrahim H, Hii KC, Ong GB, Menon BS

Med J Malaysia, 2009 Dec;64(4):325-6.

PMID: 20954561 MyJurnal

We describe a 5 1/2 year old boy who was diagnosed with mild autosomal recessive osteopetrosis based on the presence of bony sclerosis, extramedullary haematopoeisis, leukoerythroblastosis and visual impairment who had an allogeneic bone marrow transplant from a matched sibling donor. Conditioning regime was busulphan 16 mg/kg and cyclophosphamide 200 mg/kg. Apart from transient hypercalcaemia, there were no major post transplant complications. Four years post transplant, the extramedullary haematopoeisis has resolved completely with normal blood counts. Apart from a fracture after a trivial fall two months after transplant, he has not suffered any fracture related limb deformities.

Why is acute leukemia more common in males? A possible sex-determined risk linked to the ABO blood group genes

Jackson N, Menon BS, Zarina W, Zawawi N, Naing NN

Ann Hematol, 1999 May;78(5):233-6.

PMID: 10391104

Acute leukemia is more common in males at almost every age, and this fact remains unexplained. A study was carried out in northeast peninsular Malaysia, where the population is predominantly Malay, to examine whether there was a difference in ABO blood group distribution between males and females with acute leukemia (AL). The ABO blood groups of 109 male and 79 female patients with AL (98 ALL, 90 AML) were compared with those of 1019 controls. In the control population, 39.7% were group O. Among males with AL, 39.4% were group O, whereas among females with AL, the proportion was 24.1% (p=0.03). The same trend to a lower proportion of group O among females was seen if the group was divided into adult/pediatric or lymphoblastic/myeloblastic groups, though these differences were not statistically significant. If these findings can be confirmed, they suggest the presence of a "sex-responsive" gene near to the ABO gene locus on chromosome 9, which relatively protects group O women against AL, at least in our population. The existence of such a gene might also partly explain why acute leukemia, and possibly other childhood cancers, are more common in males.

Fulltext Immunisation status in hospitalised infants: reasons for incomplete immunisation

Norlijah O, Menon BS, Azlyna Nur Yanty MY, Noranida S

Malaysian Journal of Medicine and Health Sciences, 2005;1(1):51-59.

Objective: Immunisation is known to be an effective health intervention that protects children from infectious diseases. Of all children, infants are the most vulnerable if they experience a vaccine preventable disease. The aim of the study was to determine the immunisation status of hospitalised infants, to obtain the reasons of incomplete immunisation and to assess carers' knowledge on immunisation.
Methods: This was a cross-sectional study conducted in the Institute of Paediatrics at Hospital Kuala Lumpur over a 2-month period from June to August 2001. Data were collected through an interview using a structured questionnaire, with the carer of the infant. Questions pertaining to the immunisation status of the infant, reasons of incomplete immunisation and the carer's knowledge of immunisation were assessed.
Results: 115 infants were admitted during the study period; however, only 100 carers of the infants were available for an interview. The average age of the infants was 5.7 months. 22% of the infants had incomplete immunisation. 64% of them had missed more than one vaccine. The commonest missed vaccine was the 3'4 dose of diptheria-pertussistetanus (DP1) and polio vaccine. Reasons of incomplete immunisation include misconception on contraindication of immunisation perceived by both parents and health providers, missed appointment and communication breakdown with health facilities regarding appointment dates. The under-immunisation rate in the study population was 22%. The underimmunisation rate in the study population was 22%.
Conclusion: Health providers and the public need to be educated on the importance of immunisation and the associated valid contraindications.
Keywords: Infants, carer, under-immunisation, incomplete immunisation
