Cesarean section in morbidly obese women: supra or subumbilical transverse incision?
ABSTRACT The obstetrician is more and more frequently faced with the decision to perform a cesarean section in obese women. We describe a technique of supra or subumbilical transverse cesarean section (depending on the height of the projection of the upper edge of the pubic symphysis) specifically designed for morbidly obese women with a voluminous panniculus. We evaluated feasibility and associated morbidity in a retrospective descriptive series of 18 patients operated between 2003 and 2008. We assessed the quality of access to the lower uterine segment and facility to extract the fetus. The mean body mass index was 47.7 kg/m(2) (range 40.1-60.8). The incision was subumbilical in 13 women (72.2%) and supraumbilical in 27.7%. With this technique, the exposition, the section of the lower uterine segment, and extraction of the baby are simple. It can be easily generalized and quickly learnt.

ABSTRACT: The rd generation fire truck takes use of compressed gas as spraying medium. By way of the especially designed spraying device in the rd generation fire truck, the extinguishing agents mixed with compressed gas uniformly, are spraying to fire fields in microdots with high speed and high flux. The extinguishing agents’ microdots with high kinematic energy can penetrate into the flame and affront the flame with more interface areas. The extinguishing efficiency is improved significantly consequently. In a fire fighting by the rd generation fire truck, fire can be extinguished more quickly, larger field of fire can be controlled, water damage and environmental pollution is decreased too. The rd generation fire truck can also help positive pressure ventilating, cooling fire, blowing and diluting the toxic smoke, and rescuing persons from the fire. Up to the present, different kinds of the rd generation fire trucks have been successfully developed such as turbojet fire truck, water mist fire truck, compressed air-foam A/B fire truck, aerosol fire truck, compound spraying fire truck and positive pressure ventilating truck etc. They are playing important roles in fighting fire in urban building, petrochemical enterprises, underground facilities, aircrafts and others.Procedia Engineering. 01/2011; 11:418-424.

ABSTRACT: This paper presents the results of three studies of intelligibility and quality of speech recorded through a bone conduction microphone (BCM). All speech signals were captured and recorded using a Temco HG-17 BCM. Twelve locations on or close to the skull were selected for the BCM placement. In the first study, listeners evaluated the intelligibility and quality of the bone conducted speech signals presented through traditional earphones. Listeners in the second study evaluated the intelligibility and quality of signals presented through a loudspeaker. In the third study the signals were reproduced through a bone conduction headset; however, signal evaluation was limited to speech intelligibility only. In all three studies, the Forehead and Temple BCM locations yielded the highest intelligibility and quality rating scores. The Collarbone location produced the least intelligible and lowest quality signals across all tested BCM locations.Applied ergonomics 10/2010; 42(3):495-502. · 1.11 Impact Factor

ABSTRACT: L’obésité représente le plus important facteur de risque de morbidité maternelle et infantile: diminution de la fertilité, augmentation des fausses couches, des mortinaissances, des anomalies congénitales, du diabète, de problèmes hypertensifs, de terme dépassé, de césarienne et d’obésité infantile. Ces complications peuvent être diminuées par une perte de poids avant la grossesse. Les femmes enceintes obèses ou en surpoids doivent bénéficier d’une prise en charge adaptée par une équipe multidisciplinaire, et tous les aspects psychologiques, sociaux et médicaux doivent être considérés. Obesity is associated with an increased risk of adverse perinatal outcomes such as: impairment in fertility, increase in miscarriage, stillbirth, congenital anomalies, diabetes, hypertensive disorders, post term, caesarean section and infant obesity. Wasting weight before pregnancy may decrease these complications. Obese and overweight pregnant women must receive appropriate clinical care by a multidisciplinary team and all aspects, psychological, social and medical, should be considered.
