diarrhea/hypoxia

BACKGROUND Hypoxemia is a grave sequel of pneumonia, and an important predictor of a fatal outcome. Pneumonia in the neonatal period is often associated with lack of breast feeding. However, there is no published report on the impact of the cessation of breast feeding in the neonatal period on the

Bovine viral diarrhea virus (BVDV) is an enveloped, positive-sense, single-stranded RNA virus that belongs to the genus Pestivirus (Flaviviridae). The signaling pathways and levels of signaling molecules are altered in Madin-Darby Bovine Kidney (MDBK) cells infected with BVDV. Autophagy is a

Of the myriad etiologies of sensorineural hearing impairment, metabolic stress is rarely considered. I posit that severe dehydration in conjunction with hypoxia, at least during infancy, prompts permanent changes in the cochlea. In a population-based prospective study of otitis media, children

A 24-year-old man with AIDS and hemophilia A had intractable diarrhea and fever. Upon examination of stool and of a sigmoidal biopsy specimen, cryptosporidium was revealed. Approximately 2 months after admission, respiratory infection with hypoxia due to cryptosporidium developed. Paromomycin

A 25-year-old woman with documented mastocytosis developed hypoxemia with pruritus, diarrhea, headache, and hypotension on two separate occasions. The hypoxemia appeared to be related to a massive release of histamine. Resolution of the patient's symptoms was accompanied by the return of her

BACKGROUND Intestinal ischemia and reperfusion may lead to profuse secretion of water and electrolytes. The underlying mechanisms have been related to increased hydrostatic pressure, to denudation of intestinal villi, and, recently, to adenosine-mediated enhancement of chloride secretion. METHODS We

Effects of a sublethal IV dose (10 micrograms/kg of body weight) of Escherichia coli endotoxin were studied in 7 conscious ponies. Arterial blood gases and plasma lactic acid were determined periodically throughout the 180 minutes of the study. Arterial hypoxemia occurred within 5 minutes despite

Using a histochemical peroxidase technique, under conditions that preferentially stain erythrocytes, we have shown changes in the microcirculation of villi of neonatal mice infected with murine rotavirus. Between 18 and 48 h postinfection (PI), throughout all areas of the small intestine there

Hydroxylases are oxygen-sensing enzymes that regulate cellular responses to hypoxia. Transepithelial Cl(-) secretion, the driving force for fluid secretion, is dependent on O(2) availability for generation of cellular energy. Here, we investigated the role of hydroxylases in regulating epithelial

Whole colon perfusion studies and measurements of luminal prostaglandin E2 were carried out in a 41-year-old female with collagenous colitis to investigate pathophysiological mechanisms for the diarrhea. Biopsies of the colorectal mucosa had revealed a continuous 25- to 60-micron subepithelial

Diarrhea is widespread in intestinal diseases involving ischemia and/or hypoxia. Since hypoxia alters stimulated Cl(-) and water flux, we investigated the influence of such a physiologically and pathophysiologically important signal on expression of the cystic fibrosis transmembrane conductance

OBJECTIVE To determine the prevalence of intraoperative gastroesophageal reflux (GER) and postanesthetic vomiting and diarrhea, and to evaluate risk factors associated with these gastrointestinal disorders (GID) in dogs undergoing general anesthesia. METHODS Prospective observational
