polyuria/hypoxia

OBJECTIVE Four days of hypoxia produce an extensive fetal polyuria with little change in amniotic fluid volume in the ovine fetus. We hypothesized that fetal swallowing and intramembranous absorption would increase with prolonged hypoxia to offset the polyuria. METHODS After a 24-hour normoxic

Renal impairment is common in preterm infants, often after exposure to hypoxia/asphyxia or other circulatory disturbances. We examined the hypothesis that this association is mediated by reduced renal blood flow (RBF), using a model of asphyxia induced by complete umbilical cord occlusion for 25 min

The role of the submandibular salivary gland (SG) in the renal and extrarenal erythropoietin (Epo) response to hypoxia was evaluated in adult male mice with chronic renal failure from partial nephrectomy. A partial nephrectomy model for chronic renal failure was used in an attempt to evaluate

In the present study, we tested whether polycystic kidney disease (PKD) is associated with renal tissue hypoxia and oxidative stress, which, in turn, contribute to the progression of cystic disease and hypertension. Lewis polycystic kidney (LPK) rats and Lewis control (Lewis) rats were treated with

A 13-year-old girl was admitted with meningeal signs. A lumbar puncture was followed shortly by cardiorespiratory arrest. In spite of intensive resuscitation she remained comatose and severe polyuria diagnosed as diabetes insipidus appeared. The differential diagnosis of dehydration and polyuria in

The aim of this study was to identify the clinical features of patients with obstructive sleep apnea syndrome (OSAS) and investigate the impact of continuous positive airway pressure (CPAP) treatment on nocturnal urine volume. This study enrolled 53 patients with moderate-to-severe OSAS and an

OBJECTIVE To alert physicians to the possibility of pulmonary edema as a complication of diabetic ketoacidosis. METHODS We report a case of adult respiratory distress syndrome after resuscitative efforts to compensate the first episode of diabetic ketoacidosis in a previously healthy young

Results of arterial blood gas and acid-base analysis on initial samples prior to therapy were reviewed for 220 dogs admitted to the University of Georgia Veterinary Teaching Hospital. Acidemia or alkalemia was detected in 61 of 220 dogs (28%). The most common acid-base abnormality was metabolic

Hantaviruses are RNA viruses that belong to the genus Hantavirus, family Bunyaviridae. The main reservoir of hantaviruses are rodents. Humans become infected by inhaling particles of dust contaminated with faeces of rodents, that are found In Europe and Asia hantaviruses named: Hantaan, Seoul and

CONCLUSIONS Obstructive sleep apnea-hypopnea syndrome (OSAHS) in children with hypoxemia might influence the nocturnal secretion of antidiuretic hormone (ADH) that is associated with polyuria, even nocturia. OBJECTIVE The impact of OSAHS on the secretion levels of ADH was studied in pediatric

Alkalemia (pH greater than 7.50) was measured in 20 dogs admitted over a 3-year period for various clinical disorders. Alkalemia was detected in only 2.08% of all dogs in which blood pH and blood-gas estimations were made. Thirteen dogs had metabolic alkalosis (HCO3- greater than 24 mEq/L, PCO2

OBJECTIVE Snoring increases with increasing age and body mass, and repeated periods of hypoxia cause nocturnal polyuria. Accordingly, we examined the occurrence of snoring problems in patients scheduled for transurethral prostatic resection. METHODS Of 171 men scheduled for TUR-P, 41 were excluded

As with most liver diseases, the symptoms of hepatitis in dogs are nearly always aspecific: the dogs eat less, are apathetic, sometimes have polyuria/polydipsia, and sometimes have diarrhoea. Hepatoencephalopathy and ascites only occur with these symptoms in very advanced stages of chronic
