Background and purpose: Surgical site infection (SSI) is one of the most commonly reported post-operative condition. The purpose of this study was to evaluate the effect of topical vancomycin powder on prevention of SSI in spinal surgery.
Materials and methods: A single blind clinical trial was performed in 200 patients who were randomly divided into two groups. In both groups IV injection of cefazolin was done before the surgery and 24 hours later, but in case group, vancomycin powder was used before wound closure. The condition was examined for two weeks, one month and two months after the operation. In suspected cases of SSI, wound culture was done and ESR and CRP levels were also measured.
Results: In current study, no significant relationship was found between the incidence of infection and age (P=0.038). Increased BMI in weeks two and four increased the incidence of SSI in both groups. The diagnosis and type of surgery did not correlate with post-operative infection. (P=0.635) There was no significant correlation between the two groups in CRP and ESR levels within the time studied (P=0.311). However, post-operative wound healing was significantly slower in case group (P=0.041).
Conclusion: Vancomycin powder as a prophylactic treatment at incision was not found to change the risk of infection. Therefore, further studies are suggested to focus on one type of surgery merely.

Background and purpose: Bone fusion is a dynamic process and availability of calcium and balance of vitamin D can be effective in post spinal cord fusion. There are contradictory results on this issue, so, we decided to compare the effect of administration of vitamin D and alendronate on lumbosacral vertebral fusion in patients undergoing posterior spinal fusion surgery.
Materials and methods: A single-blind clinical trial was carried out in 75 patients. Patients were divided into three groups (n=25 per group) using block randomization: Alendronate group who received 70 mg oral alendronate every two weeks, Vitamin D group to receive vitamin D 50,000 units per month for six months, and control group who received routine treatment after the surgery. After six months, the patients underwent CT scan of the lumbar region for clinical assessment of lumbar fusion. Pain intensity was assessed using Visual Analogue Scale (VAS), one and six months after the surgery. Data analysis was performed in SPSS V16.
Results: Before surgery, pain intensity was higher in vitamin D group (6.36 ± 1.3) than the controls and alendronate group (P <0.0001). The last VAS in this group reached 2.12 ± 0.97 indicating decrease in pain intensity. Overall, there was a significant decrease in pain intensity in all three groups
(P<0.0001). Non-fusion was found to be more frequent in control group (16%) compared to the vitamin D (12%) and alendronate (8%) groups (P=0.900).
Conclusion: In current study, vitamin D and alendronate supplementation slightly improved lumbosacral fusion. Therefore, further studies are needed to investigate the effectiveness of combined treatment with alendronate and vitamin D on pain intensity and lumbosacral fusion in these patients.

 Background and purpose: In rhinoplasty, bleeding reduces the surgeon's vision, so bleeding control is very important. Also, edema and ecchymosis are the most common side effects of rhinoplasty. Many drugs have been used to reduce edema and ecchymosis around the eyes after surgery, but they are not suitable for all patient groups due to some side effects. Administration of magnesium sulfate before or during surgery is approved which can stabilize hemodynamic parameters, especially by reducing blood pressure and heart rate. Labtalol is also a competitive blocker of alpha-1 and beta-adrenergic receptors, which reduces heart rate and blood pressure. The aim of this study was to compare the effect of intravenous magnesium sulfate and labetalol on bleeding during rhinoplasty and also edema and ecchymosis afterwards.
Materials and methods: In this double-blind clinical trial, 60 rhinoplasty candidates were randomly assigned to receive either magnesium sulfate or labetalol. Magnesium sulfate infusion was done at 30-50mg/kg before induction of anesthesia and 10-20mg/kg/h during the surgery. Labetalol administration at 1mg/min was done during the surgery. We measured heart rate, bleeding rate, surgeon's satisfaction, postoperative complications, edema, and ecchymosis in both groups. The variables were analyzed in STATA V14 applying t-test, ANOVA, ANCOVA, and Chi-square.
Results: In this study, 86.7% of patients were women. The average bleeding in the labetalol group (50.3±28.5cc) was less than that in the sulfate group (76.7±66.4cc) and this difference was on the borderline of significance (P≤0.05). The surgeon's satisfaction was significantly higher in the labetalol group (P<0.05). Edema (24 hours after the operation) and orthostatic hypotension were significantly lower in the sulfate group (P<0.05). There was no significant difference between the two groups in terms of average heart rate, sore throat, headache, respiratory depression, and ecchymosis rate (P>0.05).
Conclusion: According to this study, magnesium sulfate can be used in rhinoplasty to reduce edema and ecchymosis.

 Background and purpose: Palate and lip cleft are prevalent congenital deformities in children that have a multi-factorial etiology involving both genetic and environmental factors. The present study assessed the orthodontic-related quality of life in children with palate and lip cleft.
Materials and methods: This descriptive cross-sectional study was conducted in 83 people with palate and lip cleft attending private dental clinics in Sari, Iran. They were selected via convenience sampling. Orthognathic quality of life questionnaire was completed by patients. The validity and reliability of the questionnaire is confirmed. The quality of life of the participants was determined from different dimensions, including social aspects, dental-facial beauty, oral function, and awareness of dental-facial beauty. One-way analysis of variance, t-test, and Pearson's correlation coefficient were used to analyze the data.
Results: The study included 41 girls and 42 boys with mean age of 12.46 years (8-18 years of age). The frequency of cleft lip and palate, cleft lip, and cleft palate were 49.4%, 22.9%, and 27.7%, respectively. The study showed no significant difference between patients with different types of cleft lip and palate in terms of the total score for quality of life and its dimensions (P=0.02). We found no significant relationship between age and dimensions of quality of life (P<0.05). Age was found to be weakly correlated with the scores of the awareness domain (r=0.24, P=0.02).
Conclusion: The quality of life was found to be at an average level in the population studied. The quality of life was not different between patients with cleft lip or palate.

 Cleft lip and palate as one of the most common congenital malformations of the oral cavity is affected by genetic and environmental factors. Subsequent aspiration during feeding, aesthetic, speech, or functional problems, and dental malformations are the main problems of neonates born with cleft lip and palate. The management of neonates with cleft lip and palate has been remarkably improved in recent years. The use of modern surgical techniques and its combination with such methods as presurgical nasoalveolar molding (NAM) is on the rise. The efficacy of preoperative casting in repairing deformed nasal cartilage in neonates with cleft lip and palate has been confirmed based on the literature. Here, we present the case of a 20-day-old neonate with bilateral cleft lip and palate who underwent presurgical nasoalveolar molding to facilitate feeding and recover facial appearance. The bony cleft of maxillary segments in the child was molded and repositioned with a combination of extra-oral elastic and intra-oral appliances. Elastic forces caused backward pressure against the protruding pre-maxilla  and careful use of forces on the cleft segments improved their positions and allowed definitive muscles and lip repair. In this technique, a nasal stent was attached to the intra-oral mouth plate and was designed to improve nasolabial anatomy.
