BackgroundPropranolol hydrochloride is a nonselective beta-adrenergic antagonist that has known activity in the myometrium. Small trials have shown propranolol decreases duration of induced labor, although those studies are limited by methodological variability.ObjectiveOur objective was to determine whether addition single dose induce labor nulliparous women would decrease total time vaginal d...

CONTEXT Ketamine evokes psychosislike symptoms, and its primary action is to impair N-methyl-D-aspartate glutamate receptor neurotransmission, but it also induces secondary increases in glutamate release. OBJECTIVES To identify the sites of action of ketamine in inducing symptoms and to determine the role of increased glutamate release using the glutamate release inhibitor lamotrigine. DESI...

Background: Orthopedic surgeries are frequently complicated with a high amount of intra-operative hemorrhage, and this bleeding has direct effect on the results these operations. Objectives: This study evaluated preoperative administration fibrinogen intraoperative in pelvic surgeries. Methods: was double-blinded, randomized clinical trial. Forty-two patients were randomly divided into two grou...

Eleven subjects participated in a prospective placebo-controlled trial to address the efficacy of pamidronate in reducing bone loss in persons with acute spinal cord injury (SCI). We administered pamidronate (treatment) or normal saline (placebo) intravenously at baseline (22 to 65 days after injury) and sequentially over 12 months, with follow-up at 18 and 24 months. Regional bone mineral dens...

A multicenter double-blind placebo-controlled study of cytidine 5'-diphosphocholine (CDP-choline) was conducted to evaluate possible clinical benefits of the drug in patients with acute, moderate to severe cerebral infarction. The patients included also suffered from moderate to mild disturbances of consciousness, and all were admitted within 14 days of the ictus. Patients were allocated random...

UNLABELLED In previous studies with glucagon-like peptide-1 (GLP-1) we have observed that this peptide modulates fluid intake and increases renal sodium excretion in healthy volunteers and in patients with diabetes mellitus type 2. The effect of GLP-1 on thirst, water intake and on osmoregulation has, however, not been examined in detail in humans. METHODS Seventeen healthy male subjects were...

The effects of intra-articular methotrexate (MTX) were compared with saline in 20 patients with persistent knee effusions due to rheumatoid arthritis (15) and psoriasis (5) in a double-blind pilot study. Clinical improvement was seen in most patients given either MTX or saline and was attributed to joint irrigation during arthroscopy and the placebo effects. MTX had a local anti-inflammatory ef...

UNLABELLED Mindfulness meditation, a cognitive practice premised on sustaining nonjudgmental awareness of arising sensory events, reliably attenuates pain. Mindfulness meditation activates multiple brain regions that contain a high expression of opioid receptors. However, it is unknown whether mindfulness-meditation-based analgesia is mediated by endogenous opioids. The present double-blind, ra...

BACKGROUND Laryngoscopy and intubation increases blood pressure and heart rate. OBJECTIVE The study aims to investigate the effect and safety of gabapentin, esmolol or their combination on the haemodynamic response to laryngoscopy and intubation. METHODS A total of 72 patients undergoing elective surgery were randomly allocated to one of the four groups. First study drug was administered or...
