We assessed the appropriateness of surgical antibiotic prophylaxis in 6 teaching hospitals in Shiraz, Iran, using the American Society of Health-System Pharmacists guideline as a reference. We reviewed the medical records of 1,000 patients who underwent 1 of 9 different surgical procedures (1 procedure per patient). The proportion of procedures in which there was compliance with all guideline recommendations was 0.3%. The most common mistakes were overuse and misuse of antibiotics.

The 14-week injection of low and high doses of ND decreases sperm quality and quantity in rats. These parameters were improved after discontinuing ND, but not recovered completely even when they are left untreated for 14 weeks.

Our findings show that the number of kisspeptin-positive cells may be affected from letrozole, and that the changes in the number of these cells may be in favor of the appearance of PCOS features in this group.

Transcutaneous electrical nerve stimulation (TENS) is a widely-practiced method to increase blood flow in clinical practice. The best location for stimulation to achieve optimal blood flow has not yet been determined. We compared the effect of TENS application at sympathetic ganglions and acupuncture points on blood flow in the foot of healthy individuals. Seventy-five healthy individuals were randomly assigned to three groups. The first group received cutaneous electrical stimulation at the thoracolumbar sympathetic ganglions. The second group received stimulation at acupuncture points. The third group received stimulation in the mid-calf area as a control group. Blood flow was recorded at time zero as baseline and every 3 minutes after baseline during stimulation, with a laser Doppler flow-meter. Individuals who received sympathetic ganglion stimulation showed significantly greater blood flow than those receiving acupuncture point stimulation or those in the control group (p<0.001). Data analysis revealed that blood flow at different times during stimulation increased significantly from time zero in each group. Therefore, the application of low-frequency TENS at the thoracolumbar sympathetic ganglions was more effective in increasing peripheral blood circulation than stimulation at acupuncture points.
