Occlusion of the internal carotid artery complicating Haemophilus influenzae meningitis.

We report a patient with occlusion of the internal carotid artery complicating Haemophilus influenzae meningitis. The etiology of this complication is discussed, along with its role in the acute seizures of meningitis, and in the chronic neurological residua of this infection.     

A nocturnal enuresis service for a deprived inner city

Aim: Glasgow is a city where 80% of the most deprived children in Scotland live within 20% of the overall population. Of 168000 children in Glasgow, an estimated 5000 aged 5-15 y have primary nocturnal enuresis. The aim of this study was to establish a nocturnal enuresis service for Glasgow. Methods: Needs assessment was performed and the incident cases were documented at school entry healthcare appraisal, at the age of 5 y. A cohort of these children was followed up at 8 y of age and symptom resolution was no better than natural remission. Parents, general practitioners, clinical medical officers and a hospital paediatrician were interviewed face-to-face about their need for a service. Results: Ten of 11 general practitioners expressed a need for a specialist service. Ten school nurse-led local nocturnal enuresis clinics were established. Accommodation, funding, default and managing alarms were major problems. School nurses enjoyed extra training and quickly became skilled therapists. Two research projects highlighted that most children at first attendance did not believe they could ever be dry, which predicted outcome. Deprived families, once motivated, could successfully undertake complex behavioural therapies. Conclusion: A comprehensive nocturnal enuresis service begins when children stop using night nappies at the age of 3-4 y. Appropriate waterproof mattress, duvet and pillow coverings should be advocated until 5 y, when desmopressin may be helpful. For continued wetting at the age of 7 y, a local service should be led by a team of well-trained nurses using enuretic alarms.     

Respiratory health in Aboriginal and Torres Strait Islander children in the Australian Capital Territory

OBJECTIVES: To measure the prevalence of respiratory symptoms and atopic disease in Aboriginal and Torres Strait Islander (indigenous) and non-indigenous children in the Australian Capital Territory (ACT). METHODS: A two-stage questionnaire survey of children in the ACT with stage two completed for children identified by parents as having respiratory symptoms or asthma in the first stage cross-sectional survey. Participants in the study were: (i) all new entrant primary schoolchildren aged 4-6 years in 1999, 2000 and 2001, 217 being indigenous children and 10 604 being non-indigenous children (80% of eligible); and (ii) Year 1-6 primary schoolchildren in 2000, with 216 being indigenous children and 14 202 being non-indigenous children (52% of eligible). Respiratory symptoms (including recent wheeze and parent-reported asthma) and other factors were measured by parental questionnaire. RESULTS: Indigenous kindergarten children had more recent wheeze (21%, odds ratio (OR) 1.4 95% confidence interval (CI) 1.0-2.0)) and parent-reported asthma (24%, OR 1.8 95% CI 1.3-2.5) than non-indigenous children (both 15%). However, indigenous children had less eczema (25%, OR 0.7 95% CI 0.5-0.9) and hayfever (14%, OR 0.7 95% CI 0.5-1.0) than non-indigenous children (32% and 19%, respectively). Among children with respiratory symptoms, the symptom severity did not differ between groups, but indigenous children were exposed to more environmental tobacco smoke (ETS) (63%, OR 3.5 95% CI 2.1-5.9) than non-indigenous children (32%). CONCLUSIONS: Indigenous children in the ACT have more respiratory morbidity but less of the atopic diseases of hayfever and eczema than non-indigenous children. Whether the respiratory morbidity represents 'asthma' or results from increased ETS exposure is unclear and needs to be further explored.     

Detection of carbamyl phosphate synthetase 1 deficiency using duodenal biopsy samples

The activity of urea cycle enzymes was assayed in duodenal biopsy specimens obtained from a female infant who presented with neonatal hyperammonaemia. All enzyme levels were normal except N-acetyl glutamate-dependent carbamyl phosphate synthetase 1 (CPS1) which was half the mean activity in normal control specimens. A similar deficiency of CPS1 was also shown in duodenal specimens from the patient's mother who became slightly symptomatic after relatively high protein meals and during pregnancy, and had spontaneously modified her diet to one with protein restriction. The patient is growing normally on a dietary regimen similar to that spontaneously adopted by her mother. Urea cycle enzyme activity in the duodenal biopsy material from the controls was similar to that found in the normal human liver and appears to have distinct advantages as a means of assaying for urea cycle defects in patients with hyperammonaemia and their relatives.     

Controlled trial of continuous inflating pressure for hyaline membrane disease

A controlled trial of elective intervention with continuous inflating pressure (CIP) was performed in infants with severe hyaline membrane disease who weighed more than 1000 g at birth. Infants entered the trial if their arterial oxygen tension (PaO2) fell below 60 mmHg while breathing a fractional inspired oxygen concentration (F1O2) greater than 0-95. 11 out of 12 infants in the CIP-treated group and 10 out of 12 in the control group survived. 7 treated and 6 control infants required mechanical ventilation. When CIP was started the Pao2 of the treated infants increased, and they breathed high concentrations of oxygen for a significantly shorter period than the control infants. During the 31-month duration of the trial 107 other infants with severe hyaline membrane disease were admitted who did not meet the criteria for entry to the trial. 37 survived after breathing high concentrations of oxygen (F1O2 greater than 0-60) spontaneously without any ventilatory assistance, and the remaining 70 infants were already being ventilated on their arrival in the unit, usually because they had required mechanical ventilation during transfer from other hospitals. The neonatal survival rate for those infants born in this hospital during the study period was 88% (50 out of 57 infants) and for those referred from other hospitals it was 69% (51 out of 74 infants). The maximum further increase in overall survival rate that might have been achieved in our population of infants if CIP had been initiated very early in the course of the illness was 5%--i.e. from 77% (101/131) to 82% (107/131).     

Endoscopic retrograde cholangiopancreatography in children

Gastroduodenoscopy and retrograde cholangiopancreatography has been performed on 25 occasions in 20 children aged between 7 and 16. Radiographs of the clinically relevant duct or ducts were achieved in 96% of attempts, with no complications. The diagnostic information proved useful clinically; in particular it provided a precise map if biliary or pancreatic surgery was being contemplated. Several unexpected congenital duct anomalies were found. This and other recent reports, particularly from Germany, indicate that endoscopic retrograde cholangiopancreatography deserves greater application in children, and can also be used in babies.
