AIM To evaluate the effectiveness of metronidazole in combination with corticosteroids in enema and mesalazine (5-aminosalicylic acid) in comparison with the same protocol without metronidazole in the treatment of chronic radiation proctitis. METHODS Sixty patients with rectal bleeding and diarrhea were randomly divided into two groups. Patients in the first group were treated with metronidaz...

Background: In order to improve the evaluation of possible rectal toxicity based on the rectal normal tissue complication probability (NTCP), we consider the fractional dependence of the NTCP on the wall thickness (tW) and rectal displacement (RM). Materials and Methods: The two-dimensional NTCP model (NTCP2D) was developed using radiotherapy plans of ten randomly selected patients with prostat...

This paper summarizes the findings from two recent studies involving the physiological effects of atropine (0 to 4 mg, im) on soldiers performing physical exercise in hot-dry environments. Study I determined the threshold of physiological effects and the gradation of these effects with increasing dosage of atropine. Study II examined the effects of exercise-heat acclimation on the reduced physi...

The use of snail mucin motifs as rectal absorption enhancer for insulin has been evaluated. The mucin motifs were extracted from the giant African snail Archachatina marginata by differential precipitation with acetone. The mucin motifs were found to have a molecular weight of 5780 Da and an isoelectric point of 3.4. At the concentrations evaluated, the mucin exhibited rectal absorption enhanci...

RATIONALE For children with specific healthcare needs, educational staff must be able to act in 'loco parentis', so that families can safely place their child in the school of choice. If a student has unstable epilepsy, staff must know its potential effects on the individual, and understand enough to manage this. Needs will vary from career advice to management issues such as administration of ...

conclusions evaluation of iranian traditional dosage forms like vaginal and rectal types could be an attractive topic of research and the current study can briefly represent the iranian traditional pharmaceutical knowledge on vaginal and rectal drug delivery. objectives the aim of this study is the investigation about iranian traditional pharmaceutical dosage forms of vaginal and rectal medicat...

PURPOSE The dose values computed with the treatment planning system and the in vivo dose measurements with semiconductor detectors in rectum during the high dose rate brachytherapy treatment fraction of the cervix carcinoma are occasionally significantly different. We've investigated the consistency of the Fletcher-Suit applicator geometry and the in vivo rectal probe's position stability durin...

in recent years, tuberculosis has had a significant rise, caused mainly by the epidemic of acquired immunodeficiency syndrome. the anorectal tuberculosis is a very rare presentation. herein, we presented a 67-year-old man who has had renal transplantation and presented with hematochezia and painful defecation since 6 months before. biopsy was taken from the lower rectal ulcerated lesion. histop...

Rectal nonsteroidal anti-inflammatory drugs (NSAIDs) are not commonly used clinically for preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. To evaluate the efficacy and safety of NSAIDs for post-ERCP prophylaxis, we systematically reviewed sixteen randomized controlled trials (involving 6458 patients) that compared rectal NSAIDs with placebo or no treatment for...

BACKGROUND During the perioperative care of infants with hypertrophic pyloric stenosis, an opioid-sparing technique is often advocated due to concerns such as postoperative hypoventilation and apnea. Although the rectal administration of acetaminophen is commonly employed, an intravenous (IV) preparation is also currently available, but only limited data are available regarding IV acetaminophen...
