Nutritional care and candidates for small bowel transplantation

Twenty two children were evaluated for small bowel transplantation between 1989 and 1994. Eight were unfit for transplantation and died within three months; a raised plasma bilirubin concentration (> 200 mumol/l) predicted death from liver failure within six months (p = 0.0001). The 11 children who were not managed by a multidisciplinary nutritional care team were less well nourished at referral, had more complications with intravenous feeding catheters, and greater early mortality while awaiting transplantation (p < 0.05). It is recommended that children with chronic intestinal failure be referred for assessment early, before liver dysfunction is established.     

Congenital misalignment of pulmonary vessels: an unusual syndrome associated with PPHN

We report a case of misalignment of pulmonary vessels and review the clinical features of all 13 cases reported to date. All were term infants dying from severe persistent pulmonary hypertension of the newborn. We have identified a triad of features that will alert neonatal clinicians to the possibility of this diagnosis: association with other non-lethal congenital malformations; delayed onset of presentation (especially after 12 h); and severe hypoxaemia refractory to conventional therapy. We recommend that any autopsy on newborn infants include a specific search for misalignment of pulmonary vessels to outline the pathophysiology and clinical significance of this disorder.     

Enhancement of erythropoiesis by erythropoietin, bovine protein and energy fortified mother's milk during anaemia of prematurity

Twenty-four premature infants, < 32 weeks gestational age, were randomly assigned in a double-blind, placebo-controlled trial to 6 weeks of treatment with either recombinant human erythropoietin (rHuEpo) 150 U/kg three times per week given sc (n= 12) or placebo (n = 12). The infants were fed a diet rich in protein (3.2 g/kg/ day) and energy (130 kcal/kg/day) based on their own mother's milk fortified with bovine protein together with moderate iron supplementation (4 mg/kg/day). During the treatment (rHuEpo versus placebo) significant differences in mean (±SD) reticulocyte count (4.8 ±1.2 versus 2.7±1.4%; P <0.01), mean packed red cell volume (PCV) (0.38 ± 0.03 versus 0.34 ± 0.04, p < 0.05) and mean haemoglobin concentration (12.6 ± 1.1 versus 11.5± 1.2 g/100 ml; p< 0.05) were found. Within the rHuEpo group, PCV and haemoglobin concentration remained unaltered from entry to 1 week after cessation of treatment whereas a significant decline was observed in the placebo group. No indications of iron deficiency were seen. We conclude that moderate doses of rHuEpo given to infants fed a diet rich in protein and energy are effective in ameliorating anaemia of prematurity. High iron supplementation does not seem to be essential for a significant erythropoietic response. No adverse effect attributable to rHuEpo was observed.

Operation for gastro-oesophageal reflux associated with severe mental retardation

One hundred and seventy six children with severe mental retardation underwent a fundoplication for considerable gastro-oesophageal reflux. There were six 'early' (3%) deaths and five 'late' deaths. Major complications developed in 17 (10%) children whereas 86 (49%) had 'minor' complications. A revision operation was required in 27 patients. Overall 142 (81%) children achieved a good result. In spite of the high complication rate and the need for a secondary operation in 15% of the patients, the quality of life for these children and their parents and carers is greatly improved by antireflux surgery.     

Suppression of brainstem reflexes in barbiturate coma

Brainstem reflexes were examined in 23 children treated with thiopentone infusion and correlated with serum thiopentone concentrations. The results suggest that if all brainstem reflexes are lost with a serum thiopentone concentration less than 40 mg/l, it is unlikely to be due to the thiopentone alone. Other causes including brain death need to be considered.     

Antibiotic management of pneumococcal infections in an era of increased resistance

Abstract: Pneumococci are a leading cause of bacterial meningitis and bacteraemia, as well as pneumonia, otitis media and sinusitis in childhood. These organisms recently have shown a dramatic increase in antibiotic resistance. Penicillin-resistant pneumococci are of special concern as they are often resistant to other unrelated antibiotics. This is of particular significance to Aboriginal children who have among the highest rates of pneumococcal infection in the world. Laboratories should now test all invasive pneumococcal isolates for penicillin and third generation cephalosporin resistance. Local treatment guidelines are required for pneumococcal infections, especially for meningitis, taking into account the prevalence of resistant strains within the community. At present, penicillin and amoxycillin remain the drugs of choice for pneumococcal infections, with the exception of meningitis where initial empirical therapy must be with a third generation cephalosporin. Judicious antibiotic use, which avoids over-prescribing and unnecessary use of broad-spectrum agents, improved living standards in underprivileged communities and introduction of an effective conjugate vaccine, able to reduce the rates of pneumococcal infection and hopefully colonization, may limit the spread of resistant strains.     

Ocular sequelae in extremely premature infants at 5 years of age

Objective To report long-term ophthalmological sequelae in extremely premature infants at 5 years and to determine the relationship between neonatal variables (including retinopathy of prematurity; ROP) and the 5 year ophthalmological outcome of these infants.
Methodology The study cohort comprised 84 surviving infants born with a birthweight <1000 g or gestational age <28 weeks from June 1985 to December 1989. All infants had an ophthalmological assessment between 34 and 40 weeks post conceptional age to document grade of ROP and were assessed at 5 years of age for fundoscopy, visual acuity, refractive error and ocular mobility.
Results Of the 84 long-term survivors 69 (82%) were formally assessed at 5 years. Overall, 30 (43%) had some form of ocular disorder. Nineteen (27%) had reduced visual acuity of <6/6 and three of these were blind. Myopia > −0.5 dioptre was noted in eight (12%), hypermetropia ≥2.0 dioptre in five (8%), astigmatism in seven (11%) and strabismus was present in nine (14%) of the cohort. There was a significant relationship ( P <0.0001) between the incidence of ocular disorders and ROP. However, even those premature children without ROP had a 31% incidence of ocular disorder at 5 years.
Conclusion Long-term ophthalmological follow-up is recommended in all extremely premature infants regardless of the presence of ROP in the neonatal period.     

The role of Epstein-Barr virus in Hodgkin's disease from different geographical areas

Recent studies have suggested that Epstein-Barr virus (EBV) may play a role in the aetiology of Hodgkin's disease. To determine the role of EBV in childhood Hodgkin's disease in different geographical areas, immunohistochemical staining and in situ hybridisation were used to analyse latent membrane protein 1 (LMP 1) and small nuclear non-transcribed RNAs (EBER-1) respectively. Testing for EBV within the Reed-Sternberg and Hodgkin's cells was carried out in childhood Hodgkin's disease from 10 different countries. The proportion of LMP 1 positive cases varied significantly, being 50% of cases from the United Kingdom (38/75), South Africa (9/18), Egypt (7/14), and Jordan (8/16), 60% from the United Arab Emirates (6/10), 70% from Australia (11/16), 81% from Costa Rica (34/42), 88% from Iran (7/8), 90% from Greece (20/22), and 100% of the 56 cases from Kenya. A sensitive polymerase chain reaction based EBV strain typing technique was established using archival tissues. EBV strain type 1 was shown to be predominant in childhood Hodgkin's disease from the United Kingdom, South Africa, Australia, and Greece. Type 2 was predominant in Egypt. EBV strain types 1 and 2 were both detected in some cases of childhood Hodgkin's disease in the United Kingdom, Costa Rica, and Kenya. The high incidence of EBV and the presence especially in developing countries of dual infection with both strain types 1 and 2 may reflect socioeconomic conditions leading to malnutrition induced immunological impairment. The possibility of HIV infection also needs to be explored.     

Renovascular and growth effects of childhood sarcoid

A boy developed early onset sarcoidosis, an extremely rare mimic of juvenile chronic arthritis. Renal granulomas caused severe hypertension and renal impairment, which was controlled by azathioprine and steroids. Severe uveitis caused visual impairment. Impaired growth and delayed puberty, not previously described in childhood sarcoidosis, required growth hormone and testosterone treatment.
