    Notes: Abstract The aim of this study was the assessment of mortality, morbidity, and associated anomalies in a series of 44 patients with congenital intrinsic duodenal obstruction admitted to the Amsterdam Pediatric Surgical Center between 1975 and 1989. Twenty-two patients were girls and 22 were boys. Severe associated anomalies were considered a contraindication for surgery in 8 children. Of the 36 who were operated upon, 8 died within the first year and a half of life. Associated anomalies consisted of trisomy 21 in 11 patients, cardiac defects in 14 (8 with trisomy 21), skeletal defects in 4, esophageal atresia in 3 (in 2 combined with imperforate anus), and various other anomalies in 5. Among the 6 patients with trisomy 21 who were operated upon, 3 died within 18 months after surgery. The surviving 3 in this group are all below the normal average weight for age. All patients without associated anomalies did well postoperatively. One patient developed a bowel obstruction at age 2 years. It appears from this study that the eventual outcome in children with duodenal atresia is determined almost exclusively by the presence or absence of associated anomalies.

    Notes: Abstract Since traction-associated hypertension seems to be a relatively unknown phenomenon, a survey was done of its incidence in children treated with skeletal traction for fractures and orthopaedic diseases. The correlation with hypercalcaemia, a possible aetiological factor, was also explored. Blood pressure was recorded three times a day with an automatic oscillometric unit during the stay in the hospital. Serum calcium, creatinine and total protein concentrations were measured once a week. Patients with pre-existing diseases or renal trauma were excluded. Arterial hypertension (systolic and/or diastolic) was found in 31/50 children (62%). In almost half of these the rise in systolic blood pressure was 10 mmHg or more above the 95th percentile. Hypertension occurred in most cases within the first 3 weeks of treatment; in 7 children it developed after 3 or more weeks of traction. All children became normotensive within 1 week after discontinuation of traction. Clinical symptoms were rare: two children complained of headache. In no instance had traction to be discontinued before the planned date because of hypertension. In the hypertensive group were more preschool children and more humeral fractures as compared to the normotensive group (n=19). Hypercalcaemia occurred in 11 children and was equally distributed in hypertensive and in normotensive children. It is concluded that arterial hypertension is a frequent finding in children in traction, but its clinical relevance is uncertain. Hypercalcaemia is not a rare finding in immobilized children, but probably plays no causative role in traction-related hypertension.

    Notes: Abstract An AustralianBabesia bigemina vaccine strain was maintained in suspension culture for 40 days. Parasite growth was compared using two tissue-culture flask sizes (25 and 75 cm2), four gas mixes (2%, 2.5%, 3% and 3.5% O2; 5% CO2; and the balance N2) and four packed blood cell (PCV) volumes (7%, 9%, 13% and 18%). The best continuous parasite yields were obtained from suspension cultures in 75-cm2 flasks at a PCV of 13% and gas mixtures of 2%–3% O2, 5% CO2 and the balance N2. Parasite yields per millilitre of culture medium were 3 times those obtained in microaerophilous stationary-phase cultures. The method has thus far been used for 6 months to produce the Australian requirements for hveB. bigemina vaccine.
