Nine children surviving severe adult respiratory distress syndrome were studied 0.9 to 4.2 years after the acute illness. They had received artificial ventilation for a mean of 9.4 days, with an Fio2 greater than 0.5 during a mean time of 34 hours and maximal positive end expiratory pressure levels in the range of 8 to 20 cm H2O. Three children had recurrent respiratory symptoms (moderate exertional dyspnea and cough), and two had evidence of fibrosis on chest radiographs. All patients had abnormal lung function; the most prominent findings were ventilation inequalities, as judged by real-time moment ratio analysis of multibreath nitrogen washout curves (abnormal in eight of nine patients) and hypoxemia (seven of nine). Lung volumes were less abnormal; one patient had restrictive and two had obstructive disease. A significant correlation between intensive care measures (Fio2 greater than 0.5 in hours and peak inspiratory plateau pressure) and lung function abnormalities (moment ratio analysis and hypoxemia) was found. A possibly increased susceptibility of the pediatric age group to the primary insult or respiratory therapy of adult respiratory distress syndrome is suggested.

« Remis au Département des manuscrits par M. Gossellin, le 19 octobre 1809. » — Au fol. 2 est la déclaration de Voltaire, reproduite en fac-similé en tête du tome III de Voltaire, Bibliographie de ses oeuvres, par G. Bengesco (Paris, 1889, in-8°) : « Je meurs en adorant Dieu, en aimant mes amis, en ne haïssant pas mes ennemis, en détestant la superstition. 1778, fév. Voltaire. »

Anorectal malformation (ARM) can be divided in high, intermediate, and low forms according to the level of termination of the rectum in relation to the pubococcygeal and ischiatic lines. Patients with Down's syndrome have a high incidence of gastrointestinal anomalies, such as tracheoesophageal fistula, duodenal obstruction, annular pancreas, Hirschsprung's disease, and ARM. In these children, ARM is generally low with or without a fistula. The mode of inheritance of ARM and its genetic relation with Down's syndrome is not known, even if the association (ARM-Down's syndrome) seems not to be coincidental. We describe here a very rare case of monozygotic twins born with the association of ARM and Down's syndrome.

The predictive potential of six selected factors was assessed in 72 patients with primary myelodysplastic syndrome using univariate and multivariate logistic regression analysis of survival at 18 months. Factors were age (above median of 69 years), dysplastic features in the three myeloid bone marrow cell lineages, presence of chromosome defects, all metaphases abnormal, double or complex chromosome defects (C23), and a Bournemouth score of 2, 3, or 4 (B234). In the multivariate approach, B234 and C23 proved to be significantly associated with a reduction in the survival probability. The similarity of the regression coefficients associated with these two factors means that they have about the same weight. Consequently, the model was simplified by counting the number of factors (0, 1, or 2) present in each patient, thus generating a scoring system called the Lausanne-Bournemouth score (LB score). The LB score combines the well-recognized and easy-to-use Bournemouth score (B score) with the chromosome defect complexity, C23 constituting an additional indicator of patient outcome. The predicted risk of death within 18 months calculated from the model is as follows: 7.1% (confidence interval: 1.7-24.8) for patients with an LB score of 0, 60.1% (44.7-73.8) for an LB score of 1, and 96.8% (84.5-99.4) for an LB score of 2. The scoring system presented here has several interesting features. The LB score may improve the predictive value of the B score, as it is able to recognize two prognostic groups in the intermediate risk category of patients with B scores of 2 or 3. It has also the ability to identify two distinct prognostic subclasses among RAEB and possibly CMML patients. In addition to its above-described usefulness in the prognostic evaluation, the LB score may bring new insights into the understanding of evolution patterns in MDS. We used the combination of the B score and chromosome complexity to define four classes which may be considered four possible states of myelodysplasia and which describe two distinct evolutional pathways.

There are many case reports of serious complications and death among obstructive sleep apnea patients (OSA) during general anesthesia or postoperative analgesia. Sedatives and anesthetic agents, pharyngeal anatomy of these patients, opiates given for analgesia, and post operative REM sleep rebound represent potential hazards for general anesthesia in OSA patients. Ideally these patients should be treated with continuous positive airway pressure (CPAP) during premedication, directly after extubation and during postoperative analgesia. Unfortunately, only about 20% of these patients are diagnosed before surgery. A special attention should be given to the symptoms and signs suggestive of OSA during preoperative visits. Screening tests should be performed in patients with suspected OSA and, if positive, a treatment should be initiated.

Dans cette étude rétrospective, nous reportons des données relatives à la chimiothérapie chez des patients atteints d'adénocarcinome pancréatique avancé, avec attention à la durée du temps qui passe entre le dernier traitement et la mort. En outre, nous analysons des paramètres cliniques et de laboratoire, enregistrés à la dernière chimiothérapie, avec le but d'identifier des facteurs de risque pour un décès proche. L'analyse rétrospective est effectuée sur des patients avec adénocarcinome pancréatique avancé, qui ont bénéficié au moins d'une ligne de chimiothérapie. Nous avons enregistré les données concernant la chimiothérapie (régimes, lignes et date de la dernière administration) et avons choisi et enregistré des facteurs cliniques et de laboratoire, qui étaient récoltés à la dernière chimiothérapie (performance status, présence d'ascite, hémoglobine, leucocytes, plaquettes, bilirubine totale, albumine, LDH, protéine C-réactive et Ca19-9). Des analyses statistiques (univariée et multivariée) sont effectuées pour étudier la relation entre ces facteurs et le temps de survie, à la recherche de facteurs prédictifs de mort imminente. Nous avons analysé les données de 231 patients: hommes/femmes, 53/47%; métastatique/localement avancé, 80/20%; âge médian 66 ans (gamme 32-85). Tous les patients sont décédés à cause de la progression de la maladie. La survie globale médiane est 6.1 mois (95% Cl 5.1-7.2). Lors de la dernière chimiothérapie, le performance status est 0-1 pour 37% et 2 pour 63% des patients. Cinquante-neuf pour cent des patients reçoivent une ligne de chimiothérapie, 32, 8 et 1% reçoivent des chimiothérapies de deuxième, troisième, quatrième ligne, respectivement. L'intervalle entre la dernière administration de chimiothérapie et le décès est <4 semaines pour 24%, 4-12 semaines pour 47% et >12 semaines pour 29% des patients. La survie médiane à partir de la dernière chimiothérapie jusqu'au décès est 7.5 semaines (95% Cl 6.7-8.4). L'ascite, la leucocytose, des valeurs élevées de bilirubine, LDH, protéine C- réactive et Ca19-9, et des valeurs abaissées d'albumine sont associés à une survie plus courte à l'analyse univariée; néanmoins, aucun de ces facteurs n'est corrélé à la survie de façon significative à l'analyse multivariée. Nous en concluons qu'une proportion significative de patients avec adénocarcinome pancréatique avancé reçoit la chimiothérapie dans le dernier mois de vie, et que les paramètres cliniques et de laboratoire enregistrés à la dernière chimiothérapie ne prédisent pas une survie plus courte.
