Pyloric stenosis: a postoperative ultrasonic study.

Six infants with hypertrophic pyloric stenosis and 20 control infants were studied ultrasonically on four occasions during the first year of life. At each examination the total diameter and muscle wall thickness of the pylorus were measured. Initially the pylorus was significantly (P less than 0.05) larger in the hypertrophic pyloric stenosis group but returned to normal values by 6 months postoperation. The control group showed a small increase in size of the pylorus over the 12 month period.

Transcutaneous oxygen monitoring in acute asthma.

Arterial blood oxygen tensions (Pao2) were compared with simultaneously obtained transcutaneous oxygen measurements (TcO2) in 15 children during an acute asthma attack and in 18 children with an illness other than asthma. A close correlation between TcO2 and PaO2 was obtained in the non-asthmatic group but not in the asthmatics. It is suggested that impaired cutaneous blood flow may explain this poor correlation.

Humidification in viral croup: a controlled trial.

Sixteen children (mean age 1.9 years) admitted to hospital with viral croup were assigned randomly to either a high humidity atmosphere or room air. No other treatment was given. During the initial 12 h both groups of patients showed a similar rate of recovery as measured by pulse rate, respiration rate, transcutaneous oxygen (TcO2), transcutaneous carbon dioxide (TcCO2) and a clinical rating. No therapeutic benefit was demonstrated from the provision of a high humidity atmosphere. The widespread use of humidification in the management of croup requires reappraisal.

Radiological abnormalities in infants with urinary tract infections.

An intravenous urogram and micturating cystourethrogram were carried out in 100 infants presenting with documented urinary tract infections. Ninety three cases were identified by suprapubic aspiration and 7 by culture of two voided urine samples containing greater than 100 X 10(6) organisms per litre. The urinary tract abnormalities were analysed in respect of their clinical importance, patient's age, sex, and prematurity (in the 10 preterm infants). Radiological abnormalities were found in 47% of the infants (40% of boys; 63% of girls). Twenty nine per cent of the infants had a urinary tract abnormality regarded as clinically important--namely grade 3 or 4 vesicoureteric reflux, reflux nephropathy, or obstructive lesions requiring surgery. Six of the 10 preterm infants had radiological abnormalities. Spontaneous resolution or improvement occurred within 6 months of birth in three of the four preterm infants with severe vesicoureteric reflux.

Whooping cough: Christchurch 1982.

Whooping cough continues to be a major health problem in New Zealand. In a twelve month period, 64 cases were admitted to the paediatric wards of Christchurch Hospital. Of these 64 patients, 24 (37.5%) were fully immunised. The possible explanations for the large number of children contracting whooping cough, who have been immunised according to the schedule used in New Zealand, is discussed.

Bleeding ears: case report of Munchausen syndrome by proxy.

A two and a half year old child presented with "bleeding" ears which proved to be factitious in origin. A previous episode of haematuria, haematemesis and melaena at age 9 months was probably also factitious. A brief discussion of Munchausen syndrome by proxy is presented.

Hyponatraemic hypertensive syndrome in two extremely low birthweight infants.

Two cases of hyponatraemic hypertensive syndrome occurring in extremely low birthweight infants are presented. Both infants experienced unilateral renal ischaemia resulting in hyponatraemia and hypertension. A proposed pathophysiological mechanism, namely unilateral renal ischaemia leading to a pressure-natriuresis in the contralateral kidney, is presented. This is associated with an increase in plasma renin and aldosterone, with a paradoxical increase in urinary sodium loss. Immature renal tubular function and relative aldosterone resistance could place the extremely low birthweight infant at increased risk for the condition. The paucity of reports suggests that the condition might be under-recognized.
