Hereditary spherocytosis.

Hereditary spherocytosis is a congenital haemolytic anaemia due to defect in spectrin-a RBC membrane protein and is transmitted as autosomal dominant. Due to this defect there is presence of characteristic spherical cell in peripheral blood smear and osmotic fragility is increased. Haemolytic anaemia, reticulocytosis, jaundice and splenomegaly are present. This article reports a case of a 9 year old boy who presented with a history of prolonged jaundice since the age of 4 years and recurrent pain in the right upper quadrant of abdomen. Clinical examination revealed jaundice, enlarged liver and marked splenomegaly. Investigations confirmed the diagnosis of hereditary spherocytosis by the presence of spherocytes in blood smear, raised reticulocytes and increased osmotic fragility. The patient was subjected to splenectomy after vaccination against coccobacillus and was discharged after proper advice and on post splenectomy antibiotic prophylaxis.

Epilepsy in children: an epidemiological study at Kathmandu Medical College Teaching Hospital Kathmandu.

OBJECTIVES: To analyze the relative frequencies of various epileptic seizures and to study the age at onset of different seizure types in Nepalese children. DESIGN: Prospective study. SETTING: Hospital outpatient based in Kathmandu, Nepal, between November 2001 to October 2002. PARTICIPANTS: 50 children diagnosed as epilepsy excluding neonatal and febrile seizures. MAIN OUTCOME MEASURE: Diagnosis and classification of cases according to the International Classification of Epilepsy of the International League Against Epilepsy [ILAE] and number of patients in each category with various ages at first seizure. RESULT: Generalized seizures (78%) were 3.54 times commoner than partial seizures (22%). Most frequent seizure types were generalized tonic clonic (36%), tonic (16%), complex partial (14%), atonic (12%) and absence (10%). Generalized clonic, simple partial and partial with secondary generalization, each had less than 5% frequencies. In 40% cases the first seizure occurred when aged between 2-5 years. In partial seizures the peak age at onset was observed below 6 years while primary generalized seizure was more frequently seen in age group 2-10 years. CONCLUSION: More paediatric patients with primary generalized seizures (78%) were observed than with partial seizures (22%). In this age group, the most frequent seizure type was generalized tonic clonic (36%) with the peak frequency of age at onset of seizures in 2-5 years.

A case report of Gilbert Syndrome.

Gilbert syndrome is benign, often familial condition characterized by recurrent but asymptomatic mild unconjugated hyperbilirubinemia in the absence of haemolysis or underlying liver disease. If, it becomes apparent, it is not until adolescence and then usually in association with stress such as intercurrent illness, fasting or strenuous exercise. Virtually all patients have decreased level of UDP-Glucuronosyltransferase, but there also is evidence for a defect in hepatic uptake of bilirubin as well. This case is reported due to its rarity. The prevalence of Gilbert syndrome in U.S is 3-7% of the population.

One year follow up study of term babies born at Kathmandu medical college teaching hospital.

OBJECTIVE: To study the mean, standard deviation and centiles for anthropometry and haemoglobin in healthy term infants followed up to 12 months of age. DESIGN: Cohort study. SETTINGS: Kathmandu Medical College Teaching Hospital (KMCTH) in Kathmandu. SUBJECT: Consecutive healthy term newborns Method: 100 consecutive healthy term newborns were enrolled at birth.19 babies were lost in follow up. So, 81(45 male, 36 female) healthy, full term infants were followed up from birth to 12 months of age. Anthropometry (weight, length, and head circumference) and haemoglobin were measured at birth, 6 weeks, 6 months, 9 months and 12 months of age. Haemoglobin was estimated by Hemocue microcuvette method. The data so obtained was subjected to statistical analysis by using SPSS computer package. MAIN OUTCOMES: Mean, centile and standard deviation score values for weight (Kgs), infant length (cms), head circumference (cms) and haemoglobin (gm/dl) at birth, 6 weeks, 6 months, 9 months and 12 months of age. RESULTS: Out of 100 babies enrolled, data presented here is for the remaining 81 babies. Among 81 babies, 76 were appropriate for gestational age (AGA) and 3 were small for gestation (SFD). The mean, standard deviation and percentile values are presented for anthropometry (weight, length and head circumference) and haemoglobin at birth, 6 weeks, 6 months, 9 months and 12 months of age. The mean birth weight was 3.05 kg (SD 0.41). The mean infant length and head circumference at birth were 49 cm (2.28) and 33.8 cm (SD1.4) respectively. The mean haemoglobin at birth was 15.7 gm/dl (SD 2.29). At 12 months of age mean weight, length, head circumference and haemoglobin were 9 kg (SD 0.81), 73.5 cm (SD 2.9), 45 cm (SD 1.2 ) and 11.1 gm/dl (SD 1.41) respectively. Almost 50% of the babies at 6 weeks, 9 months and 12 months of age were found to be anaemic (Hb < 11 gm/dl). Among the babies, 49% were exclusively breast fed for 6 months of age. Other feeding practices seen were, mothers breast feed with water supplementation (25%), mothers breast feeding with formula feed (16%) and formula feeding only (5%). National and international comparisons of anthropometry and haemoglobin data are shown in table.

Efficacy and tolerability of Ketotifen in Nepalese asthmatic children: a clinical study.

OBJECTIVE: To assess the efficacy of Ketotifen in asthmatic children and to record its adverse effects, if any. DESIGN: Prospective clinical trial. SETTING: Pediatric asthma follow up clinic of a teaching hospital. PARTICIPANTS: 23 asthmatic children between 3 and 15 years; 100% completed the trial on full protocol. INTERVENTIONS: Ketotifen 1mg (adjusted according to body weight, 50 mcg/kg/dose) orally twice daily for 9 months. MAIN OUTCOME MEASURES PRIMARY OUTCOME: Decrease in frequency of asthmatic attacks and severity of exacerbations with improvements in peak expiratory flow rates (PEFR). Other measures included decrease in bronchodilator requirement, steroid doses and parental perception regarding patient quality of life. RESULTS: 34.78% children were symptom free by the end of 2nd 3 months and 65.21% had no further attack by the end of 3rd 3 months of Ketotifen prophylaxis. Those children with activity and sleep 'affected' (8.69%) and 'may be affected' (30.43%) together improved to 'may be affected' group (21.73%) by the end of 2nd 3 months and further reduced to 8.69% by the conclusion of 3rd 3 months. The duration of exacerbations was reduced in the remaining cases. Variability of PEFR decreased from 26.08% to 8.69% of children after the 3rd 3 months of Ketotifen prophylaxis. No significant adverse effect of therapy was observed during the study. CONCLUSION: Oral Ketotifen is effective and well tolerated for use in prophylactic treatment of bronchial asthma in children.

Upper GI endoscopy in children- in an adult suite.

UNLABELLED: Although Upper GI endoscopy is commonly performed in adults, paediatric endoscopy is not available in many of our referral centres. The efficacy and safety of upper GI endoscopy in paediatric age group performed in adult suite of Kathmandu Medical College is reviewed. PATIENTS AND METHOD: A retrospective study of endoscopies performed on children aged up to 15 years in an adult endoscopy suite of Kathmandu medical college over last one year is presented. All cases were the referred cases from paediatric unit for various problems. RESULTS: Endoscopy in paediatric group comprises only 6% of total upper GI endoscopies performed during the same year. Sex ratio was almost equal. Most cases (87%) were performed under local anaesthetic and well tolerated by the patients. Recurrent abdominal pain (RAP) was the commonest indication and among them one third of cases had significant positive finding. CONCLUSION: Upper GI endoscopy is a useful diagnostic tool in children. Where specialized paediatric endoscopy units are not feasible i.e. developing countries, endoscopic services to children can be safely provided in adult endoscopy suite with or without sedation. Upper GI endoscopy is well tolerated by children even without sedation.

Hemoglobin status in children in the age group 6 to 60 months.

Objective of this study was to see the prevalence rate of anemia in children among the age of 6-60 months who attended paediatric out patient department of Kathmandu Medical College. 100 children aged 6-60 months were randomly selected for hemoglobin measurement and anthropometry. Detailed clinical examination including anthropometry was done. Hemoglobin was checked by Hemocue machine with prior consent from the attendant. Mean height, weight, and body mass index (BMI) were measured. Forty six percent of the study group population had hemoglobin <11 gm/dl, similar numbers of the children were in the various state of malnutrition. Twenty eight percent of the children came from outside of the valley residing in Kathmandu. Fifty percent were illiterate or had primary level education only. Poverty, high rate of illiteracy and lack of awareness on taking appropriate food were important factors related to such a high childhood anemia. Iron supplementation should be given to the children particularly in the age group of 6 months to 3 years.
