Evaluation of anamnestic criteria for the identification of patients with acute community onset viral gastroenteritis in the emergency department--A prospective observational study.

Background: To our knowledge no clinical criteria for the identification of community onset viral gastroenteritis in individual patients have been evaluated systematically with modern PCR-based diagnostic assays as gold standard.

Objective: The aim of this study was to identify factors independently associated with the detection of virus by PCR in rectal swab samples from patients with acute community onset gastroenteritis.

Methods: A prospective observational study was conducted from December 2010 through March 2011 at the emergency department (ED) of a large teaching hospital.

High-frequency, high-intensity transcutaneous electrical nerve stimulation as treatment of pain after surgical abortion.

The aim of the study was to compare the pain-relieving effect and the time spent in the recovery ward after treatment with high-frequency, high-intensity transcutaneous electrical nerve stimulation (TENS) or intravenous (IV) conventional pharmacological treatment after surgical abortion. Two-hundred women who underwent surgical abortion and postoperatively reported a visual analogue scale (VAS) pain score3 were included. The patients were randomised to TENS or conventional pharmacological treatment for their postoperative pain.

Dopamine or norepinephrine infusion during thoracic epidural anesthesia? Differences in hemodynamic effects and plasma catecholamine levels.

Background: During thoracic epidural anesthesia, an intravenous dopamine infusion augments the systemic pressure response and modifies plasma catecholamine levels. If such an altered response occurs when norepinephrine is infused is not clear. Therefore, dopamine and norepinephrine induced circulatory and catecholamine responses were studied before and during thoracic epidural anesthesia.

Autoregulation and vasodilator responses by isoflurane and desflurane in the feline renal vascular bed.

Background: Inhalational anesthetics have agent-specific effects on the renal circulation. This study investigated renal vasodilator responses produced by either autoregulation, 0.8% isoflurane (ISO) or 3.

Effects of desflurane on systemic, preportal and renal circulatory responses to infra-renal aortic cross-clamping in the pig.

Background: Different pharmacological approaches have been used in the control of cardiovascular responses to surgical infra-renal aortic occlusion (AXC). The aim of the present study was to explore the modulatory effects of desflurane (DES) on these responses.

Methods: The study was performed in normoventilated chloralose-anesthetized pigs (n = 14).
