health effects of a hot environment on outdoor workers at a construction site 1) and thermal limits of men in moderate to heavy work in tropical farming 2). Both studies highlighted the importance of heat stress for outdoor workers and the implementation of administrative and engineering controls to reduce heat stress exposure. Our interest in this topic is in relation to agricultural workers i...

Combined analysis of high-resolution seismic images of the Alaska and Cascadia subduction zones reveals where metamorphic fl uids are released. Both images show the subducted oceanic crust as a dipping low-velocity layer with a clear termination depth. However, in Alaska the crust is thicker (15–20 km compared to 8 km) and terminates at greater depth (120 km compared to 40 km) than in Cascadia....

Objectives . To study the possibility of combining acid-catalytic cyclohexanol dehydration and alkoxycarbonylation formed cyclohexene with carbon(II) oxide in a single reactor order to achieve high yields target cyclohexyl cyclohexanecarboxylate product under mild conditions using Pd(OAc) 2 –PPh 3 – p -toluenesulfonic acid catalytic system. Methods The combined process took place toluene medium...

The concentration of bicarbonate was measured in serum samples from 106 children with gastroenteritis and dehydration. A concentration less than 22 mmol/l was more common in children with severe dehydration, but the magnitude of bicarbonate reduction was not significantly different with increasing degrees of dehydration. Doctors should not rely on the serum bicarbonate concentration when assess...

BACKGROUND Acute evaluation and treatment of children presenting with dehydration represent one of the most common situation in the pediatric emergency department. To identify dehydration in infants and children before treatment, a number of symptoms and clinical signs have been evaluated. The aim of the study was to describe the performance of clinical signs in detecting dehydration in childre...

Small volume resuscitation fluids continue to be of interest to the military and limited volume resuscitation is becoming more common in the treatment of hemorrhage in the civilian community. With renewed interest to undertake a large US-Canada multi-center clinical trial of hypertonic saline alone or combined with dextran (HSD) possibly in 2006, concerns related to the safe use of this product...

CONTEXT Acute pancreatitis due to pancreatic ischemia is a rare condition. CASE REPORT In this case report we describe a 57-year-old male who developed an acute necrotizing pancreatitis after running a marathon and visiting a sauna the same evening, with an inadequate fluid and food consumption during both events. CONCLUSIONS Pancreatic ischemia imposed by mechanical and physical stress and...

Dehydration is a frequent etiology of morbidity and mortality in elderly people. It causes the hospitalization of many patients and its outcome may be fatal. Indeed, dehydration is often linked to infection, and if it is overlooked, mortality may be over 50%. Older individuals have been shown to have a higher risk of developing dehydration than younger adults. Modifications in water metabolism ...
