1.  The Role of Thiamine Pyrophosphate in Prevention of Cisplatin Ototoxicity in an Animal Model 
The Scientific World Journal  2013;2013:182694.
Objective. The aim of this study was to evaluate the effectiveness of thiamine pyrophosphate against cisplatin-induced ototoxicity in guinea pigs. Materials and Methods. Healthy guinea pigs (n = 18) were randomly divided into three groups. Group 1 (n = 6) received an intraperitoneal injection of saline solution and cisplatin for 7 days, group 2 (n = 6) received an intraperitoneal injection of thiamine pyrophosphate and cisplatin for 7 days, and group 3 (n = 6) received only intraperitoneal injection of saline for 7 days. The animals in all groups were sacrificed under anesthesia, and their cochleas were harvested for morphological and biochemical observations. Results. In group 1, receiving only cisplatin, cochlear glutathione concentrations, superoxide dismutase, and glutathione peroxidase activities significantly decreased (P < 0.05) and malondialdehyde concentrations significantly increased (P < 0.05) compared to the control group. In group 2, receiving thiamine pyrophosphate and cisplatin, the concentrations of enzymes were near those of the control group. Microscopic examination showed that outer hair cells, spiral ganglion cells, and stria vascularis were preserved in group 2. Conclusion. Systemic administration of thiamine pyrophosphate yielded statistically significant protection to the cochlea of guinea pigs from cisplatin toxicity. Further experimental animal studies are essential to determine the appropriate indications of thiamine pyrophosphate before clinical use.

2.  Postoperative cephazolin usage is sufficient for preventing infection after septoplasty procedure 
Allergy & Rhinology  2011;2(2):e54-e57.
The use of antibiotics in septoplasty is a common practice among most ear, nose, and throat doctors; however, there are few studies proving the efficacy, which is considered as unnecessary by some authors. The aim of this pilot study was to evaluate the effect of two different kinds of antimicrobial agent on efficacy and safety after septoplasty surgery and to show that use of cephazolin, 1.0 g, postoperatively, might be sufficient for preventing infection after septoplasty procedure. Patients were randomly divided into two groups with a simple randomization method. The first group of 80 patients received cephazolin, 1.0 g i.v., once postoperatively and the second group of 80 patients received amoxicillin–clavulanate orally for 7 days postoperatively (1000 mg). An early and late postoperative questionnaire and nasal endoscopy evaluation was performed and patients were followed up in the outpatient service to investigate the presence of complications. There was no significant difference in postoperative pain between groups A and B, using visual analog scale scores at the 1st postoperative day. There were no differences related to the amount of purulent discharge found at the lower margin of the inferior turbinate through nasal endoscopy performed on the 14th day postoperatively. There were no statistical significances among groups for complications rates and postoperative endoscopic evaluation. Septoplasties are considered potentially contaminated surgeries, and cephazolin, 1.0 g i.v., given once postoperatively is enough to prevent potential complications with its easy and effective use.
