    Description / Table of Contents: Résumé La ligne de réflexion du péricarde autour du pôle veineux du cœur est étudiée au cours de 107 dissections anatomiques. L'étude porte sur des cadavres frais avec des cavités cardiaques remplies artificiellement. Les auteurs étudient les variations du nombre de vv. pulmonaires, les diamètres et les portions intra-péricardiques de ces veines et les caractéristiques des récessus veineux pulmonaires, post-cave et du sinus oblique du péricarde. Ces variations déterminent cinq types de morphologie péricardique différents. Une classification est alors proposée. Les résultats obtenus, en particulier lors de l'étude des vv. pulmonaires, ne sont pas ceux de la littérature probablement car les cœurs étudiés ici sont, au préalable, placés en réplétion pour être le plus près possible de la disposition du vivant. Ces données morphométriques sont utiles pour l'enseignement anatomique, pour l'imagerie du médiastin, pour la chirurgie des tumeurs malignes, et la transplantation pulmonaire.
    Notes: Summary The authors have studied the pericardial recesses of the venous aspect of the heart. They report 107 anatomical dissections on fresh cadavers with the cardiac cavities artificially filled. Variations in the number of the pulmonary vv., in their diameters and their pericardial segments are reported. The characteristics of the oblique sinus, of the postcaval and pulmonary recesses are also reported. These variations define five types of pericardial morphology. A classification is proposed. These results differ from those in the literature, possibly because the pericardial reflection is delineated in diastolic filling of the cavities. These morphometric data are useful in anatomic instruction, imaging of the mediastinum, and the surgery of malignant tumors and pulmonary transplantation.

    MRI of intramedullary cavernous haemangiomas (1995)

    Notes: Abstract We reviewed 11 cases of intramedullary cavernous haemangiomas (IMCH) studied by MRI, to assess its diagnostic value in these lesions. Follow-up MRI was obtained in five patients 7 days-2 years following the initial study. In one case a postoperative examination was obtained. The diagnosis was pathologically proven in ten cases, and supported in the last by a family and personal history of cavernous haemangiomas. A reticulate appearance with areas of mixed signal intensity in both T1-and T2-weighted images was the most common finding. Homogeneous high, low or intermediate signal intensity was each found in one case, Two small lesions gave low signal. A rim of low signal was less common than in cerebral cavernous haemangiomas. In one case, the brain showed more than 20 lesions with the MRI appearances of cavernous haemangiomas. In two of five patients, serial preoperative MRI showed progressive disappearance of high-signal areas on both T1-and T2-weighted images. To find a haemorrhagic intramedullary lesion on MRI is not rare. Although the appearances are not pathognomonic, an IMCH can be suggested. We suggest that the following characteristics may help: (1) a personal and/or family history of cavernous haemangiomas; (2) typical MRI appearances of mixed acute, subacute and chronic haemorrhage; (3) a tendency for signal intensity to decrease on follow-up; (4) normal spinal angiography; and (5) associated brain lesions.

    Pharmacokinetics of intravenous omeprazole in children (1994)
    Springer
    European journal of clinical pharmacology 47 (1994), S. 181-185 
    Details
    ISSN: 1432-1041
    Keywords: Omeprazole ; pharmacokinetics ; children ; genetic polymorphism

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Abstract This study was undertaken to define the pharmacokinetics of omeprazole in children and included 13 patients, heterogenous in terms of age (0.3 to 19 years), underlying disease and biological constants, indication of omeprazole administration and associated therapy. The dose administered ranged from 36.9 to 139 mg·1.73 m−2. The pharmacokinetic parameters of omeprazole were: systemic clearance, 0.23 1·kg−1·h−1; volume of distribution, 0.45 1·kg−1; elimination half life 0.86 h; but were highly variable between individuals. Dosage, differences in hepatic and renal function and associated therapy may contribute to inter-individual variability. Within the range of doses administered, the pharmacokinetic parameters were similar to those reported in adults. The drug has been well tolerated in all children.

    Effect of Meal and Intravenous Erythromycin on Manometric and Electrogastrographic Measurements of Gastric Motor and Electrical Activity (2000)
    Springer
    Digestive diseases and sciences 45 (2000), S. 525-528 
    Details
    ISSN: 1573-2568
    Keywords: electrogastrography ; erythromycin ; manometry ; children

    Notes: Abstract Electrogastrography (EGG) measures, on the skin surface, the myoelectrical activity attributable to gastric smooth muscle cells. The physiological significance of signal amplitude and variation has not been clearly established. The increased signal amplitude after eating a meal may be related to increased contractile activity or to gastric distension. This study investigates the effect of increased gastric motor activity, unaccompanied by gastric distension, on the EGG recording and compares it to the effect of a meal. Nine children (3 months to 15 years old), were assessed by antroduodenal manometry for chronic intestinal pseudoobstruction (N = 5), chronic vomiting (N = 2), and abdominal distension (N = 2). Synchronized EGG recording was performed simultaneously. During the study, four children were given a meal and five were given intravenous erythromycin 3 mg/kg over 1 hr. The ratio of the antral motor index (MI = number of waves × sum of amplitudes) determined 1 hr before a meal (or erythromycin) to that determined 1 hr after a meal (or during intravenous erythromycin) was calculated. The ratio of the running total spectrum power of the electrical signal at the same times was also calculated. Antral MI increased after a meal [MI ratio (mean ± se) 5.33 ± 2.2] and after intravenous erythromycin (MI ratio: 9.36 ± 2.6). The amplitude of the electrical activity also increased after the meal [power ratio (mean ± se) 3.01 ± 0.65] and after intravenous erythromycin (power ratio: 1.23 ± 0.39), but the increase was greater after the meal (P 〈 0.05 vs intravenous erythromycin). No correlation was found between antral MI ratio and running total spectrum power ratio. In conclusion, the increased amplitude of the gastric electrical activity recorded by the EGG after a meal seems to be only partly due to the increase in antral motor activity. The increase in power is also related to gastric distension.
