Purpose: Fistulotomy is considered the most effective treatment for anal fistula; however, it carries a risk of incontinence. Sphincteroplasty in the setting of fistulotomy is not standard practice due to concerns regarding healing and potential infectious complications. We aimed to compare the outcomes of patients who underwent fistulotomy with primary sphincteroplasty to those who did not undergo repair. Methods: This was a retrospective review of consecutive patients who underwent fistulotomy for cryptoglandular anal fistula. All operations were performed by one colorectal surgeon. Sphincteroplasty was performed for patients perceived to be at higher risk for continence disturbance. The main outcome measures were the healing rate and postoperative septic complications. Results: In total, 152 patients were analyzed. Group A (fistulotomy with sphincteroplasty) consisted of 45 patients and group B (fistulotomy alone) included 107 patients. Both groups were similar in age (P=0.16) and sex (P=0.20). Group A had higher proportions of multiple fistulas (26.7% vs. 6.5%, P<0.01) and complex fistulas (mid to high transsphincteric, 37.8% vs. 10.3%; P<0.01) than group B. The median follow-up time was 8 weeks. The overall healing rate was similar in both groups (93.3% vs. 90.6%, P=0.76). No significant difference between the 2 groups was noted in septic complications (6.7% vs. 3.7%, P=0.42). Conclusion Fistulotomy with primary sphincter repair demonstrated a comparable healing rate to fistulotomy alone, without an increased risk of postoperative septic complications. Further prospective randomized studies are needed to confirm these findings and to explore the functional outcomes of patients who undergo sphincteroplasty.

Objective: To evaluate the antibacterial activity of the extracts of Laurus nobilis against three Gram-positive bacteria (Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212 and Staphylococcus epidermidis CIP 444) and two Gram-negative bacteria (Escherichia coli ATCC 35218 and Pseudomonas aeruginosa ATCC 27853). Also, the antibiofilm activity has been investigated against the biofilm produced by Staphylococcus epidermidis CIP 444. Materials: The polysaccharides, essential oil, and fatty oils extracted from the plant were used in broth microdilution methods to study the minimal inhibitory concentration, and then the minimal bactericidal concentration was determined. Results: The results showed that alginate, fucoidan, fatty oils and essential oil have good antibacterial activities against the 5 bacterial strains, and a negligible biofilm eradication activity of fucoidan, laminaran, fatty oil, and essential oil was observed, but a promising biofilm eradication activity was obtained with alginate, which showed a reduced biofilm mass even at low concentration. Conclusions: The extracts obtained have promising antibacterial capacities which need further investigation for them to be incorporated in medical or nutritional applications.

Objective: To identify the anti-Toxoplasma antibodies from blood donors who referred to blood transfusion bases of Jahrom County, using ELISA method. Methods: Based on the prevalence and characteristics method, 400 serum samples were collected from blood donors referred to Jahrom blood transfusion bases, Southern Iran, during 2010-2011, designed at testing by ELISA. IgM and IgG antibodies against Toxoplasma gondii were tested using ELISA kits (Dia-Pro) on serums. The data were analysed by SPSS 19 software. Results: Review of 400 cases, 54 of them were IgG positive for parasites (13.5%) and 346 of those with negative IgG (86.5%). In IgM examination, 1.75% of them have been positive IgM (7 cases) and 98.25% of them were IgM negative (393 cases). By comparing the different group ages, 40-50 year age group had the highest prevalence of IgG positive (17.9%) and the age group of 30-40 years had the highest incidence of IgM negative (2.5%). Conclusions: Due to the serological infection rate of toxoplasmosis obtained from this study, toxoplasmosis should be considered as a significant transfusion risk factor in Jahrom and also in any region with similar situations.
