Abstract

International audience; Weirs or run-of-river dams can disrupt bedload transfer with negative ecological effects downstream due to sediment starvation. The way and the degree to which bedload is trapped is nevertheless not straightforward and few studies have examined this topic. This study focuses on a 13-km-long reservoir of the Rhône River, France, created by a diversion dam equipped with bottom gates. Our main objective was to determine the degree of alteration of the bedload transfer downstream and to identify to which extent the implementation of Ecomorphogenic Flow (EmF), defined as environmental flow whose objective is specifically to increase bedload transfer through the reservoir to promote downstream habitat diversity, could increase bed mobility. The results show that the potential for morphological adjustments in the reservoir was already low before dam completion (1968) in response to a substantial decrease in coarse sediment supply, but that this potential was progressively reduced due to the impoundment. However, the bedload transfer continuity has been at least partially maintained since dam completion. According to numerical simulations, only particles smaller than medium gravels (d

Abstract

We describe an acute onset of diabetes mellitus during third trimester of pregnancy revealed by ketoacidosis, complicated by fetal death, which could evoke fulminant type 1 diabetes, a novel subtype of type 1 diabetes first described in Japan and rarely described in Caucasian people. Diagnosis of diabetic ketoacidosis could be made on simple signs as abdominal pain, vomiting or ketone bodies on urinary multistix. Capillary glycaemic control is necessary to distinguish fast from ketoacidosis. The treatment of this severe imbalance must be initiated in emergency., (Copyright © 2010 Elsevier Masson SAS.

Abstract

Malignant hyperthermia (MH) in a pediatric patient during sevoflurane anesthesia with only a minor rise of endtidal CO(2) is described. MH was considered because of increased rectal temperature. The outcome was favorable after the initiation of a few simple measures (increased minute ventilation, cessation of sevoflurane). As recommended by the regional MH Reference Center, dantrolene was not used. In vitro contracture tests were performed on muscle biopsies from both parents. A strong contracture in response to halothane confirmed the father's MH susceptibility, thereby according a high probability of an MH episode in his son.

Abstract

Malignant hyperthermia susceptibility (MHS) is a subclinical pharmacogenetic disorder caused by an impairment of skeletal muscle calcium homeostasis in response to triggering agents. While in vitro contracture testing (IVCT) is the gold standard for defining MHS, molecular analysis is increasingly used to diagnosis MHS. Mutations associated with MHS have been reported in two genes: RYR1 and CACNA1S. Mutations in RYR1 are also responsible for central core disease (CCD), a myopathy that can be associated with a positive IVCT response. We report here the results of correlation studies performed with molecular, pharmacological, histological, and functional data obtained in 175 families (referred to as confirmed (129) or potential (46) MHS families). Extensive molecular analysis allowed us to identify a variant in 60% of the confirmed MHS families, and resulted in the characterization of 11 new variants in the RYR1 gene. Most mutations clustered to MH1 and MH2 domains of RYR1. Functional analysis allowed us to assign a causative role for seven MHS mutations that we propose to add to the panel of MHS mutations used for genetic testing. The use of genetic data to determine MHS status led to a 99.5% sensitivity for IVCT. IVCT-positive/mutation-negative diagnoses were analyzed not only in terms of specificity for IVCT, but also to assess the presence of a second MHS trait in families, and the genetic heterogeneity of the disease. Histological analyses revealed the presence of cores in more than 20% of muscle biopsies originating from 242 genotyped and tested MHS patients who did not present with clinical symptoms. This indicates that these patients must be considered as MHS patients with cores, and are clearly differentiated from CCD patients who have been tested positive for MHS., (Copyright 2005 Wiley-Liss, Inc.)

Abstract

The aim of this study was to analyse the follow-up of patients with a history of endotracheal intubation and/or tracheotomy because of respiratory distress, surgical necessity or long-term resuscitation. Twenty adults were followed up in a ENT facility for laryngeal or tracheal stenosis, of which 7 cases were diagnosed during 1994. This study shows that, in patients with a history of intubation, or intubation followed by tracheotomy, the stenosis developed within two months after resuscitation with a favourable outcome. After tracheotomy only, the stenosis developed later (2 months or more) with more recurrences. The diagnosis of stenosis was made on gradual or acute dyspnea. While respiratory resuscitation methods are essential and often life-saving, they are not without complications. Laryngeal and tracheal stenosis could be largely prevented by more careful techniques of endotracheal intubation and tracheotomy. Periodic endoscopic airway surveillance is useful to detect stenosis even when there is no clinical symptom.
