BACKGROUND Pulsatile tinnitus, unlike idiopathic tinnitus, usually has a specific, identifiable cause. Nonetheless, uncertainty often arises in clinical practice about the findings to be sought and the strategy for work-up. METHODS Selective literature review and evaluation of our own series of patients. RESULTS Pulsatile tinnitus can have many causes. No prospective studies on this subject...

effects of acute systemic hypoxia on the cardiovascular system (cys) and respiration of spontaneously breathing cats were studied in two conditions. 1): hypoxic air (6-8% 02 in n2) was given to the animal to induce systemic hypoxia for 20 minutes. hyperventilation at this condition lowered arterial c02 tension (pac02 hypocapnia). 2): in the second run, induction of hypocapnia was prevented by a...

base deficit is a non-respiratory indicator of acid base status. aim of this study is to assess relationship between the base deficit value in immediate post operative period of cabg and valvular heart disease with cardiopulmonary and in hospital outcome of patient. a total of 136 consecutive with cabg and valvular heart disease scheduled in study. 20 variables were determined during the pre-in...

arteritis due to strongylus vulgaris is a well-known cause of colic in horses and donkeys. the current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by s. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial o...

The propagation of blood flow along the fetoplacental arterial system has been hypothesized to have a compensatory response to placental anomalies that may result in fetal stress. When the placenta generates increased resistance, the umbilical artery blood flow would decrease and in the worst scenario become absent, which will lead to fetal asphyxia and hypoxia. To compensate for the decreased ...
