    Notes: : Interleukin-8 (IL-8) is a pro-inflammatory cytokine highly expressed in inflammatory bowel diseases, but whose effects on intestinal motility are unknown.〈section xml:id="abs1-2"〉〈title type="main"〉Aim: To characterize the role of IL-8 in the contraction of rat intestinal segments.〈section xml:id="abs1-3"〉〈title type="main"〉Methods: Contractile response to acetylcholine (ACh 10−6 M) in terminal ileal segments (including mucosa) from Wistar rats was measured before and after incubation (15, 30, 60 or 90 min) with IL-8 (1 ng/mL), and after 60 min of incubation with different doses of IL-8 (0, 0.1, 0.5, 1, 10 and 100 ng/mL). The effects of blocking neural transmission with tetrodotoxin (TTX) and inhibiting protein synthesis (cycloheximide) were tested. The contractile response of longitudinal muscle–myenteric plexus preparations (i.e. without mucosa) was measured after 60 min of incubation with 0.1 and 1 ng/mL of IL-8.〈section xml:id="abs1-4"〉〈title type="main"〉Results: IL-8 increased ileal contraction induced by ACh 10−6 M. This augmentation was significant after 60 min of incubation (58%, P=0.01) and persisted after 90 min (18%, P=0.04). A 60-min incubation period showed a dose-related effect, beginning at 0.5 ng/mL (30%, P=0.003) and reaching a peak at 1 ng/mL (58%, P=0.01). The same effect was also observed on colonic segments. TTX did not affect the IL-8 increase of ACh-induced contractions, which was completely abolished by cycloheximide. IL-8 had no significant effect on longitudinal muscle–myenteric plexus preparations.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusion: In vitro, IL-8 increases contractile response of the ileum to ACh in a dose-dependent manner. This effect is not neurally mediated, but seems to involve protein synthesis by intestinal mucosa.

    Description / Table of Contents: Résumé Les jumeaux conjoints représentent 1 pour 50000 naissances, les thoracopages sont les plus fréquents et présentent le plus souvent des malformations léthales. Une étude anatomique des malformations rencontrées chez les jumeaux conjoints sternopages a été effectuée dans le but d'évaluer l'intérêt de l'échographie anté-natale pour le diagnostic de ces malformations. Nous avons étudié anatomiquement cinq jumeaux conjoints (3 féminins, 2 masculins). Un examen nécropsique a été réalisé quatre fois, montrant dans tous les cas les mêmes malformations: sternum commun, coeur unique malformatif, union des parenchymes hépatiques, grèle commun aboutissant à une poche kystique située sur le segment iléal de l'intestin grèle, à la terminaison de l'artère mésentérique supérieure. Le diagnostic de jumeaux conjoints avait dans tous les cas été porté en anté-natal par les échographies, à un terme moyen de 26,6 semaines d'aménorrhée (extrèmes 21–26). Les malformations retrouvées par les échographies étaient: dans tous les cas une masse cardiaque unique, trois fois une union des parenchymes hépatiques, une fois une poche kystique du grèle. Le diagnostic avait conduit quatre fois à une interruption médicale précoce de la grossesse. Dans un cas une césarienne avait été pratiquée, les enfants étaient morts 48 heures après. L'échographie anté-natale nous semble actuellement le meilleur examen pour faire le diagnostic de jumeaux conjoints et rechercher des malformations léthales conduisant à une interruption de la grossesse.
    Notes: Summary Among conjoined twins (1 out 50000 births), thoracopagus occurs most frequently and is generally lethal. Our anatomical study of five sets of sternopagus twins (3 female, 2 male) was performed to determine the ability of prenatal sonography to detect these anomalies. Autopsy in four cases revealed identical malformations: common sternum, single malformed heart, joined hepatic parenchyma, and a common small bowel leading to a cystic dilatation situated on the ileal segment at the end of the superior mesenteric artery. The diagnosis of conjoined twins was made in all cases by prenatal sonography at the mean time of 24.6 gestation weeks (range 19–34). The malformations detected by prenatal sonography were a single cardiac mass (all cases), joined hepatic parenchymas (3 cases), and an ileal cystic dilatation (1 case). Pregnancy was terminated in four cases. In one case cesarean delivery was performed, and the infants died 48 hours later. Prenatal sonography currently seems to be the best examination for diagnosis of sternopagus twins and the detection of lethal malformations thus allowing interruption of pregnancy.

    Description / Table of Contents: Résumé A partir de l'étude comparative de coupes anatomiques dans les plans transversal, frontal, sagittal et des coupes IRM correspondantes du petit bassin, les auteurs déterminent quels sont les plans de coupe et les modes IRM les plus performants pour l'étude morphologique des muscles élévateurs de l'anus. Cette étude montre l'intérêt de l'examen IRM dans le bilan des malformations ano-rectales opérées.
    Notes: Summary A comparative study of serial anatomic sections in the transverse, frontal and sagittal planes with corresponding MRI sections of the pelvis allowed the authors to define the most suitable sectional planes and MRI modes for a morphologic study of the levator ani muscle. This study shows the value of MRI examination in the assessment of anorectal malformations.

    Notes: Abstract Background: The aim of the study was to evaluate the results of laparoscopic Nissen fundoplication (LNF) with simultaneous percutaneous endoscopic gastrostomy (PEG) in children with gastroesophageal reflux (GER) disease documented by upper gastrointestinal contrast and/or pH monitoring and/or esophageal endoscopy. Methods: Fifteen LNF + PEGs were performed in children with pathologic antecedents: ten neurologically impaired children, two ORL (otorhinolaryngeal) pathologies. Two cases of AIDS, and one neuroblastoma. In one case, disruption of the fundoplication occurred during insufflation of the stomach. The child was reoperated on the 3rd day using an open procedure, so she was excluded from the results of the LNF. Results: Two children had postoperative complications: one with cardiac insufficiency, one case of dehydration. Fourteen LNFs were controlled at 3 months by gastroesophageal X-ray and pH-metry. The 14 gastroesophageal X-rays were normal in 12 cases; gastroesophageal reflux was present in two cases. Twelve pH monitorings were analyzed (two technical failures), the median time pH〈4 was 0.2% (0–20). Only one pH monitoring was pathologic (pH〈4: 20%). This recurrent reflux to led to a second LNF with a good clinical result. Conclusions: In conclusion, it is possible to perform LNF and PEG during the same operative procedure. Short-term results are satisfactory with 14% recurrent GER. Long-term results need to be evaluated.
