Intermittent clobazam therapy in febrile seizures.

OBJECTIVE: To evaluate the efficacy of intermittent clobazam therapy in preventing the recurrence of febrile seizures and to assess its safety. METHODS: The study was a prospective, randomized, double-blind placebo-controlled trial conducted in the Department of Child Health, Christian Medical College Hospital, Vellore between July 2001 and September 2002. Neurologically normal children between 6 months and 3 years of age with a history of febrile seizures and no evidence of acute CNS infection or EEG abnormality were included into the study. 19 children in a clobazam group and 20 in the placebo group were randomly allocated. Temperature reduction measures with paracetamol and tepid sponging were advised to all children. In addition the dispensed medication was to be administered at the onset of fever and continued for 48 hours irrespective of the duration of fever. The children were then monitored for seizures and adverse effects of clobazam. The children were followed up for a mean period of 9.9 months. The analysis was done on the number of febrile episodes in both the groups. RESULTS: There were a total of 110 episodes of fever during the study period. Mean number of febrile episodes in the clobazam group was 3.1 and in placebo group 2.56. Six (12.5%) of the 48 episodes in placebo group and one (1.7%) of 60 episodes in clobazam group had seizure recurrence. This was statistically significant (p = 0.01). Drowsiness and weakness were present equally in both clobazam and placebo groups whereas ataxia was present only in the clobazam group, the difference being statistically significant (p=0.04). CONCLUSION: Intermittent clobazam therapy is an effective measure in the prevention of recurrence of febrile seizures. The ataxia due to clobazam was much lower than that reported with diazepam.

Osteopetrorickets.

Rickets is a paradoxical complication of osteopetrosis resulting from the inability of the osteoclasts to maintain a normal calcium-phosphorus balance in the extracellular fluid. Detection of rickets in a child with osteopetrosis is necessary, because treatment of the rickets with vitamin D leads to improvement in activity, decrease in irritability, improvement of appetite, and protects against recurrent respiratory tract infections. If bone marrow transplantation is feasible, then for better results, rickets should be completely treated prior to the transplantation.

Clinical profile and outcome of acute renal failure in South Indian children.

This was a retrospective study to assess the clinical profile of children admitted with acute renal failure and to identify factors associated with poor outcome. Fifty-four children (age one month to 12 years) with acute renal failure were studied. Males outnumbered females (38/54; 70%). The leading precipitating causes for renal failure were acute gastro-enteritis (85%), underlying renal pathology (43%), proven sepsis (22%) and suspected sepsis (22%). The main presenting complaints were diarrhoea (86%),oliguria (72%), rapid respiration (37%), oedema (37%), vomiting (19%) and seizures (13%). All patients underwent standard investigations and treatment. Forty-eight per cent of patients required peritoneal dialysis and 15% required ventilation. The overall mortality was 52%. Underlying renal pathology and sepsis both contributed to the high morbidity and mortality. Mortality due to sepsis was 83%; it was 65% in dialysed patients and 100% in those requiring ventilatory support. Biochemical profile of the above patients showed that hyperkalaemia was significantly associated with high mortality (83%) as against 75% in those with hypokalaemia and 33% with normal levels (p<0.001). Patients with hyponatraemia and hypernatraemia similarly had an adverse outcome. Acidosis, seen in 20 patients, had a mortality of 45%. The outcome was poorer in those with high creatinine levels (63%).

Comparison of blood gas values in arterial and venous blood.

OBJECTIVE: To compare pH and PCO2 values of simultaneously obtained arterial, arterialized capillary, and venous blood samples and also to compare oxygen saturation (ASaO2) measured in arterial blood and oxygen saturation by pulse oximetry (PSaO2). METHODS: Prospective study was done in the children admitted in the Pediatric Intensive Care Unit of Christian Medical College Hospital Vellore, requiring critical care. All the three blood gas samples (arterial, capillary and venous) were taken simultaneously and analyzed. Oxygen saturation by pulse oximetry was also recorded. RESULTS: 50 children aged 14 days to 12 years were included in the study. Arterial and capillary pH values were highly correlated (r2=0.9024, p<0.0001). Out of 16 children with arterial acidosis 9(56%) were identified by capillary blood gas. Arterial and venous pH values also showed good correlation (r2=0.8449, p<0.0001). The PCO2 values of arterial and capillary blood gases were found to be highly correlated (r2=0.9534, p<0.0001). The capillary blood gas accurately reflected the arterial PCO2 in 41 (82%) patients. Arterial and venous blood gas PCO2 values had less correlation (r2=0.5917, p=0.011). The arterial oxygen saturation (ASaO2) and oxygen saturation by pulse oximetry (PSaO2) were correlated moderately (r2=0.7241, p<0.0001). CONCLUSION: Even though arterial blood gas analysis is the gold standard, and when an arterial blood gas sample cannot be obtained, a combination of arterialized capillary blood gas and pulse oximetry can be effectively used in acutely ill children of all ages. Venous samples have a good correlation with arterial samples for pH but are not useful for monitoring blood gas status in acutely ill children.

Unusual cause for miliary lung mottling in a child.

A 12-year-old boy presented to us with a diagnosis of disseminated tuberculosis which was made based on a history of prolonged fever, multiple neck swellings and radiological findings of bilateral multiple micronodular opacities. Examination showed a diffuse thyroid gland swelling. He was diagnosed to have papillary thyroid carcinoma with distant metastases to cervical lymphnode on histopathology and to lungs.
