Chediak-Higashi syndrome presenting in accelerated phase.

Chediak-Higashi Syndrome (CHS) is a rare autosomal recessive disorder, characterized by silver hair, recurrent infections, partial oculo-cutaneous albinism, mild coagulation defect and progressive neuropathy. The characteristic feature of CHS is the presence of huge lysosomes and cytoplasmic inclusions within different body cells like the white blood cells. The disease has an early onset but usually presents in an accelerated phase. We present a case of a 2 years old boy with high grade fever, bilateral cervical lymphadenopathy, hepatosplenomegaly, abdominal distention of 28 days duration. He was diagnosed with Chediak-Higashi syndrome in accelerated phase on the basis of clinical presentation, morphological findings on peripheral blood film and bone marrow aspirate.

Ambulatory short-course high-dose oral amoxicillin for treatment of severe pneumonia in children: a randomised equivalency trial.

BACKGROUND: WHO case management guidelines for severe pneumonia involve referral to hospital for treatment with parenteral antibiotics. If equally as effective as parenteral treatment, home-based oral antibiotic treatment could reduce referral, admission, and treatment costs. Our aim was to determine whether home treatment with high-dose oral amoxicillin and inpatient treatment with parenteral ampicillin were equivalent for the treatment of severe pneumonia in children. METHODS: This randomised, open-label equivalency trial was done at seven study sites in Pakistan. 2037 children aged 3-59 months with severe pneumonia were randomly allocated to either initial hospitalisation and parenteral ampicillin (100 mg/kg per day in four doses) for 48 h, followed by 3 days of oral amoxicillin (80-90 mg/kg per day; n=1012) or to home-based treatment for 5 days with oral amoxicillin (80-90 mg/kg per day in two doses; n=1025). Follow-up assessments were done at 1, 3, 6, and 14 days after enrollment. The primary outcome was treatment failure (clinical deterioration) by day 6. Analyses were done per protocol and by intention to treat. This trial is registered, ISRCTN95821329. FINDINGS: In the per-protocol population, 36 individuals were excluded from the hospitalised group and 37 from the ambulatory group, mainly because of protocol violations or loss to follow-up. There were 87 (8.6%) treatment failures in the hospitalised group and 77 (7.5%) in the ambulatory group (risk difference 1.1%; 95% CI -1.3 to 3.5) by day 6. Five (0.2%) children died within 14 days of enrollment, one in the ambulatory group and four in the hospitalised group. In each case, treatment failure was declared before death and the antibiotic had been changed. None of the deaths were considered to be associated with treatment allocation; there were no serious adverse events reported in the trial. INTERPRETATION: Home treatment with high-dose oral amoxicillin is equivalent to currently recommended hospitalisation and parenteral ampicillin for treatment of severe pneumonia without underlying complications, suggesting that WHO recommendations for treatment of severe pneumonia need to be revised.

Assessment of coverage levels of single dose measles vaccine.

OBJECTIVE: To study the consequences of low coverage levels of a single dose of measles vaccine. DESIGN: Case series. PLACE AND DURATION OF STUDY: The study was conducted in the Department of Paediatrics, Rawalpindi General Hospital (RGH) from January 2001 to August 2001. PATIENTS AND METHODS: Information about 68 admitted cases of measles was collected on a structured proforma with reference to epidemiological profile, vaccination history and comorbidities. RESULTS: Mean age observed in measles cases was 2 years and 8 months with a range from 3 months to 8 years. Maximum number of cases reported were <1 year of age (n=22, 32%). Fifty percent of cases were seen among vaccinated children. Seventy-five percent (n=51) had history of contact with a measles case. Pneumonia was the commonest complication followed by acute gastroenteritis, encephalitis, febrile convulsions, oral ulcers, oral thrush, eye changes of vitamin-A deficiency and pulmonary tuberculosis (T.B.) in descending order of frequency. Fifty-four cases were successfully treated for complications of measles and discharged. Nine cases left against medical advice. Five patients died--all of them had encephalitis either alone (n=1) or in combination with pneumonia and acute gastroenteritis (n=4). CONCLUSION: There is a dire need to increase the immunization coverage to reduce the rate of vaccine failure and achieve effective control of measles.
