The purpose of this study was to investigate the time dependent effects among factors affecting duration of work disability after compensated low-back pain. A postal survey involving 238 compensated workers at 39 companies was performed between January 5, 2004, and March 23, 2004. Cox proportional hazard regression analysis was used to model the effect of demographic, work-related, and injury f...

Background and aim: Melissa officinalis was traditionally used for pain relief and treatment of some diseases. The aim of the study was to compare the effect of mefenamic acid and Melissa officinalis (Melissa) on pain management in primary dysmenorrhea.

conclusions post-operative pain in rectal acetaminophen group was less than that in intravenous acetaminophen group, and rectal acetaminophen group demanded their first additional analgesic medication later. results data analysis indicated a significant relationship between reduction of postoperative pain and the use of intravenous or rectal acetaminophen (p = 0.0001); in group receiving iv ace...

Medications, including topical 0.2% glyceryl trinitrate (GTN), can reduce anal spasm and pain after excisional hemorrhoidectomy. GTN after stapled hemorrhoidopexy was compared with routine postoperative management. Patients with symptomatic grade 3/4 hemorrhoids were recruited. After stapled hemorrhoidopexy, residual perianal skin tags were excised as appropriate. Those requiring double purse-s...

INTRODUCTION Complementary and alternative medicines have been used to decrease labor pain for many years. Despite reports that some of these methods reduce pain, increase maternal satisfaction, and improve other obstetric outcomes, they have received limited attention in the US medical literature.

Duration Calculus (DC) is a real-time logic with measurement of duration of propositions in observation intervals. It is a highly expressive logic with continuous time behaviours (also called signals) as its models. Validity checking of DC is undecidable. We propose a method for validity checking of Duration Calculus by reduction to a sampled time version of this logic called well sampled Inter...

The aim of this study was to investigate experimentally if 5-HT3 single nucleotide polymorphisms (SNP) contribute to pain perception and efficacy of the 5-HT3-antagonist granisetron and sex differences. Sixty healthy participants were genotyped regarding HTR3A (rs1062613) and HTR3B (rs1176744). First, pain was induced by bilateral hypertonic saline injections (HS, 5.5%, 0.2 mL) into the massete...
