[Neonatal esophago-gastro-duodenoscopy. Apropos of 123 examinations performed on 107 newborn infants].

UNLABELLED: Upper gastrointestinal endoscopy is frequently used in the neonatal period. The aim of this study was to assess the frequency of the different lesions occurring as well as to precise indications of upper gastrointestinal endoscopy in neonates. POPULATION AND METHODS: A retrospective study including 107 neonates referred between October 1986 and April 1995 has been achieved in the pediatric gastroenterology unit of the Lille University Hospital. Various factors were analysed: gestational age, sex, reasons for endoscopy and macroscopic lesions observed. Three groups were constituted according to macroscopic findings; group I: normal aspect (n = 22); group II: isolated esophagitis (n = 27); group III: esogastritis or gastroduodenitis or esogastroduodenitis (n = 38). Chi 2 test was performed for statistical analysis. RESULTS: Signs recalling esophagitis (cry during feeding) were more frequent in group II than in group III: 37% vs 13% (P < 0.03). The neonates undergoing endoscopy for life-threatening events were more frequent in group I than in group II or III, respectively: 59% vs 15% (P < 0.01) and 59% vs 8% (P < 10(-4). Upper gastrointestinal endoscopy led to a precise diagnosis in 80% of the neonates. However 95% of those examined for hematemesis presented macroscopic lesions. CONCLUSIONS: Hematemesis and suspicion of esophagitis are good indications for upper gastrointestinal endoscopy in neonatal period. In life-threatening events and suspicion of pyloric stenosis, upper gastrointestinal endoscopy is only complementary of more contributive other examinations.

Nutritional status of children with acute lymphoblastic leukemia: a longitudinal study.

To evaluate the nutritional consequences of acute lymphoblastic leukemia and its treatment, 15 children with leukemia were studied. Anthropometric data, fat-free mass by impedance, energy intake, and resting energy expenditure (REE) were determined at diagnosis and on days 22, 36, and 71 of the treatment. Interleukin (IL)-1 beta, IL-6, interferon-gamma, and tumor necrosis factor were also measured. Fifteen healthy control subjects were matched for age and sex. Body weight and height and body composition were comparable at all times of the study, although three children were underweight at diagnosis (weight-for-height < 85% of French standards). Although two different methods were used for dietary recall in the two groups, energy intake expressed as a percentage of normal recommended values for age and sex was lower in patients than in control subjects (104 +/- 19%) on day 1 (47 +/- 32.1%) and day 22 (58 +/- 24%), but was comparable on day 36 (85 +/- 71%) and day 71 (85 +/- 48%). This low energy intake involved both carbohydrates and fats. Energy and carbohydrate intakes improved significantly during the study in patients. The nonprotein respiratory quotient (RQ) in patients was significantly lower than in control subjects (0.84 +/- 0.04) on day 1 (0.79 +/- 0.02) but was comparable on day 71. The REE of the patients on day 1 (5057.8 +/- 1588.4 kJ/24 h) and day 71 (4844.7 +/- 116.1 kJ/24 h) and of the control subjects (4313.8 +/- 823.5 kJ/24 h) was not significantly different. Cytokines remained undetectable on days 1, 36, and 71. The results showed that at the time of diagnosis and during this period of chemotherapy there was no evidence of raised REE. The poor intakes during the first month of chemotherapy were recent as shown by the parents' questionnaire responses and the absence of consequences in body composition. The transient decrease in RQ seemed to be an adaptative mechanism to the poor carbohydrate intake. No indication of undernutrition in the patients as a group was evident during the first 71 d of treatment although further long-term nutritional assessment is needed.

Normal gastric histology in Helicobacter pylori-infected children.

BACKGROUND: In adults, Helicobacter pylori infection is always associated with gastritis or ulcer. However, very active gastritis and ulcers are rarely seen in children. The aim of the present work was to study the relationships between H. pylori and gastric mucosa in children. METHODS: Eighty infected children and adolescents including 48 (60%) neurologically impaired institutionalized patients, aged 2 months-22 years (mean 11.7 +/- 5.2 years) were studied retrospectively. All the patients underwent gastroscopy, and three antral and two fundic biopsy specimens were taken for histology and bacteriology. RESULTS: A normal gastric mucosa was found in 22 of 80 patients (27.5%), whereas the others had gastritis (n = 58, 72.5%). There were no statistical differences between patients with normal histology and those presenting with gastritis for age, sex, ethnic background, symptoms, and the degree of bacterial colonization. The macroscopic aspect of gastritis was less frequently found in children with a normal histology compared with those with histological gastritis (p < 0.001). CONCLUSIONS: These data show that H. pylori infection can be associated with a normal gastric histology in children.

Nutritional impact of antipseudomonas intravenous antibiotic courses in cystic fibrosis.

OBJECTIVE: To evaluate the short term effects on nutritional status of home intravenous anti-pseudomonas antibiotic courses in cystic fibrosis (CF) patients chronically colonised with Pseudomonas aeruginosa. DESIGN: A prospective study involving 38 CF patients, mean age 10.9 (SD 4.3) years (range 4.3 to 22.2 years), presenting with pulmonary exacerbations of P aeruginosa infection. The patients received a 14 day antibiotic course of intravenous ceftazidime (200 mg/kg/day) and either amikacin (35 mg/kg/day) or tobramycin (15 mg/kg/day). Nutritional evaluation on days 1 and 14 involved measurements of weight, weight/height ratio (per cent of predicted value), energy intake (per cent of recommended daily allowances), serum prealbumin, and body composition assessed by two methods: bioelectrical analysis (BIA) and skinfold anthropometry. The non-parametric Wilcoxon t test was used for statistical analysis, with a Bland-Altman plot to assess the degree of agreement between the two methods of evaluating body composition. RESULTS: Weight increased by 1.0 (0.8) kg (p < 0.001); weight/height increased from 94.4(12.2)% to 98(12.7)% (p < 0.001), energy intake from 107(32)% to 119(41)% (p < 0.02), and prealbumin from 183 (63) to 276 (89) mg/l (p < 0.001). Fat mass increased by 0.8 (1.0) kg (p < 0.001), without any significant change in fat-free mass. The limits of agreement between BIA and anthropometry were -0.7 kg and +1.1 kg. CONCLUSIONS: Antibiotic courses allow an improvement in nutritional status in CF patients, with a gain in fat mass.

Influence of recombinant interferon alpha on nutritional status and growth pattern in children with chronic viral hepatitis.

UNLABELLED: Anorexia and weight loss are frequently reported as adverse effects during recombinant interferon alpha (rIFN-alpha) treatment. The aim of the present study was to assess both nutritional status and growth of children and adolescents treated with rIFN-alpha for chronic viral hepatitis. Eleven patients aged 4-16 years with histologically proven chronic active hepatitis (hepatitis B, n = 9; hepatitis C, n = 2) receiving rIFN-alpha subcutaneously thrice a week for 6 months were studied. Weight and height increments were assessed during the 6 months before starting rIFN-alpha. Weight and height were measured every 3 months (M0, M3, M6) during the 6 months of rIFN-alpha treatment, then every 6 months during the follow up period (6-36 months). Weight decreased in every child during rIFN-alpha treatment (weight loss varies from 0.5 to 2.6 kg after 3 months of treatment). Weight/age Z-score decreased from 0.12 at M0 to -0.69 at M3 (P < 0.01), then increased between M3 and M6 (-0.33) (P < 0.01), but normalized (0.02) only 6 months after completion of treatment. Nutritional status was significantly impaired during treatment (Z-score for weight/height decreased from 0.18 at M0 to -0.74 at M3, P < 0.01) and recovered progressively thereafter. Height and height velocity were not modified by rIFN-alpha treatment. A reduction of the caloric intake observed between M0 and M3 might explain these features. CONCLUSION: Significant but transient abnormalities of the nutritional status are encountered constantly at the beginning of rIFN-alpha therapy without any deleterious effect on growth. Information of the families and nutritional intervention during treatment should be required, in order to limit the importance of weight loss.

[Sleeping position, prevention of sudden death syndrome and gastroesophageal reflux].

Based on results of epidemiological studies, dorsal or lateral sleeping positions are now recommanded in the prevention of sudden infant death syndrome (SIDS). This raises an ethical question about the attitude towards the ventral positioning therapy for gastroesophageal reflux (GOR). The consensus conference considers that the ventral position should only be recommanded in GOR when the benefit appears to outweigh the risk of SIDS that it induces. The conference proposes that for infants with simple uncomplicated reflux, sleeping in the prone position should not be introduced in the first line treatment. Prone positioning should be restricted to complicated cases resistant to dietary and medical measures.

[Liver transplantation in an adolescent with cystic fibrosis].

BACKGROUND: Orthotopic liver transplantation (OLT) is an effective treatment for patients with cystic fibrosis end stage liver disease, especially those with only mild pulmonary involvement. Long-term follow-up in such transplanted patients is still lacking. CASE REPORT: A 15-year-old girl with cystic fibrosis received an OLT because of severe decompensated cirrhosis. She had been colonized by Pseudomonas aeruginosa for 3 years and had pancreatic insufficiency; she also had mild glucose intolerance. Postoperatively she developed diabetes mellitus requiring insulin therapy for 9 months. Oral cyclosporin was poorly absorbed so that she was given a new emulsion of cyclosporin (Neoral) that was better absorbed. A rapid pubertal catch-up was obtained but the patient remained colonized by Pseudomonas aeruginosa. CONCLUSION: This 3-year postoperative follow-up confirms that OLT can represent a good alternative in those patients with severe liver disease and mild pulmonary involvement.

Current concepts and issues in the management of regurgitation of infants: a reappraisal. Management guidelines from a working party.

Regurgitation in infants is a common problem. Recent issues, such as the increased risk of sudden infant death in the prone sleeping position, the finding of persisting occult gastro-oesophageal reflux with feed thickeners, and the increasing awareness of the cost-benefit ratio of medications may challenge the currently recommended management approach. A round table was organized to elaborate on the impact of (i) the pro supine sleeping campaigns in relation to sudden infant death and (ii) advancement in medical treatment on therapeutic strategies in regurgitating infants. The participants were opinion leaders from Europe and North America (Belgium, Canada, France, UK, Italy, Switzerland and The Netherlands). The importance of parental reassurance is stressed. As a consequence of the supine sleeping campaigns aiming to decrease the incidence of sudden infant death syndrome, the "prone elevated sleeping position" is no longer advised as a first-line therapeutic approach, although it is still recommended in "complicated reflux". It is emphasized that milk thickeners are an adequate therapeutic tool for regurgitation, but not in reflux disease. According to the literature, the efficacy of (alginate )antacids, although very popular in some countries, is questionable. These recommendations will be of interest to first-line paediatricians, since about 40% of their patients, according to the literature, present because of regurgitation.

Simultaneous tracheal and oesophageal pH monitoring during mechanical ventilation.

OBJECTIVE: To simultaneously record tracheal and oesophageal pH in mechanically ventilated children to determine: (1) the feasibility and safety of the method; (2) the incidence of gastro-oesophageal reflux (GOR) and pulmonary contamination; and (3) their associated risk factors. DESIGN: Prospective study. SETTING: Paediatric intensive care unit in a university hospital. PATIENTS: Twenty mechanically ventilated children (mean age 6.7 years) who met the following inclusion criteria: endotracheal tube with an internal diameter of 4 mm or more (cuffed or uncuffed), mechanical ventilation for an acute disease, no treatment with antiacids, prokinetics, or H2-receptor blockers, and no nasogastric or orogastric tube. METHODS: The tracheal antimony pH probe was positioned 1 cm below the distal end of the endotracheal tube. The oesophageal antimony pH probe was positioned at the lower third of the oesophagus. pH was recorded on a double channel recorder and analysed with EsopHogram 5.01 software and by examination of the trace. The following definitions were used: GOR index, percentage of time pH < 4; pathological GOR, GOR index > 4.8%; tracheal reflux, fall in tracheal pH < 4, 4.5, or 5, or a decrease of one unit from baseline, in both cases preceded by an episode of GOR. The results were analysed statistically by Fisher's exact and the Kruskal-Wallis test. RESULTS: The procedure was well tolerated and the median duration of analysable recording was 6 hours (range 5-22.6). Pathological GOR was observed in eight (40%) children. GOR was more frequent with an uncuffed endotracheal tube than with a cuffed one (p = 0.01). Tracheal reflux (pH < 4) was observed in four children (20%) without clinical evidence of pulmonary aspiration. Episodes of tracheal reflux were associated with a GOR index > 10% (p < 0.01) and were more frequent with a maximal inspiratory pressure of < 25 cm H2O (p = 0.03), but were not related to the indication for mechanical ventilation, whether the endotracheal tube was cuffed or not, age, or drug treatment. CONCLUSIONS: Simultaneous tracheal and oesophageal pH monitoring was feasible in the setting of this study. Tracheal reflux can occur without pathological GOR, and GOR may occur without tracheal reflux. Further prospective studies in larger groups of patients are now justified.

Resting energy expenditure and energy substrate utilization in children with Duchenne muscular dystrophy.

The high prevalence of obesity at an early stage of Duchenne muscular dystrophy (DMD) could result not solely from reduced physical activity, but may also involve low resting energy expenditure (REE), abnormal nutrient utilization, or overfeeding. We hypothesized that the dramatic muscle mass loss in DMD should reduce the REE. REE was measured by indirect calorimetry in 13 9-13-y-old DMD boys (5 obese, 8 nonobese) and 9 male age-matched controls. Muscle mass was estimated from 3-d creatinine excretion in urine. Daily energy intake was estimated from 7-d diet records. In the nonobese DMD group (NODMD) the muscle mass was reduced by 71%, and the REE was 13% lower than in controls (47.5 versus 54.6 kcal.h-1, p < 0.05). Postabsorptive respiratory quotients appeared higher in both DMD groups than in the controls; however, the difference was significant only for the NODMD group (0.88 versus 0.83, p < 0.05). Respiratory quotients were not different between the two DMD groups. Diet records were not contributive in revealing a different dietary behavior between groups. Our results suggest that: 1) muscle mass loss in DMD is associated with a low REE, 2) low postabsorptive fat utilization might occur at an early stage of the disease, and 3) obesity is not associated with an increase in fat utilization in DMD. This study warrants further research to test low REE and low fat utilization as risk factors in developing obesity in DMD.
