BACKGROUND Stoma formation is often complicated by early skin irritation and infection. Rates for local irritation are reported at 3–42% while peristomal infections and abscesses occur in 2–14.8% of cases. Intraoperative bowel content spillage is an avoidable risk factor.1 We describe a cost efficient method of minimising spillage and forcepselated bowel trauma using a Foley catheter. This tech...

To achieve successful delivery of drug locally as well as systematically rectal route has proved its potential. The main objective of this research work was to evaluate the in vivo performance of paracetamol Suppocire CP suppository. Initially, suppositories were prepared, evaluated for their physicochemical parameters and in vitro drug release. An in vivo investigation of paracetamol availabil...

To investigate if there is a synergy between the presence of the Malassezia yeasts and the adverse reaction during treatment of scalp psoriasis with calcipotriol scalp solution, patients were treated with itraconazole to reduce the number of Malassezia yeasts. This study was a double-blind, placebo-controlled parallel group study between oral itraconazole or placebo for 8 weeks in patients with...

Combined exposure to different irritants in the workplace may lead to irritant contact dermatitis, which is the main type of occupational dermatitis among bakers and confectioners. Following previous work on "tandem irritation", a panel of healthy volunteers was exposed twice daily for 4 days to the organic fruit acids: citric, malic, and lactic acid, either alone or in tandem application with ...

 Toxic by all routes of exposure – inhalation, ingestion, skin contact  Carcinogenic in humans  Inhalation of vinyl chloride causes coughing, wheezing and breathlessness, headache, ataxia, drowsiness and coma  Ingestion of vinyl chloride causes nausea, vomiting, diarrhoea, abdominal pain, and haematemesis may occur.  Skin contact causes irritation, pain, burns and contact dermatitis. Rapid...

Despite many potent biological activities, retinoids such as retinoic acid (RA) and retinal possess dose-related broad side effects. In this study, we show that this problem, which has been unsolvable for a long time, can be tackled through a controlled release strategy in which retinal is continuously delivered to the skin via sustained release from proretinal nanoparticles. The water dispersi...

The BALB/c 3T3 NRU test is probably the cytotoxicity test that has been used most frequently in formal validation programs, all of which were aimed at evaluation of cytotoxicity in predicting eye irritancy. Large-scale studies to be mentioned here are Phases I, II, and III of the Cosmetic, Toiletry, and Fragrance Association (CTFA) validation program (Gettings et al., 1991, 1992, 1994a, 1994b);...
