Itch is one of the most common and uncomfortable side effects of neuraxial anesthesia. Its incidence is higher especially in cesarean section. The aim of this study was to compare the effect of ondansetron and propofol at doses lower than the hypnotic dose on the treatment of itch induced by intrathecal fentanyl in cesarean section.
In this prospective study, 90 patients with American Society of Anesthesiologists (ASA) class I and class II with an average age of 30 years and first time cesarean section underwent intra-spinal anesthesia with 25 μg fentanyl and 10 mg bupivacaine 0.5%. Women were randomly divided into two groups of 45. One group received 4 mg ondansetron and another group received 10 mg propofol at first and then 10 μg / kg / min through infusion. The incidence and severity of itch were recorded on the basis of the visual scoring system during operation and during recovery.
FINDINGS:The highest incidence of itch was 30 to 60 minutes after injection. The incidence of itch during surgery was 2.22% and 7.26%, and during recovery was 7.6% and 8.8%, in the ondansetron and propofol groups, respectively (p=0.5, p=0.4). The mean itch severity scores during surgery were 1.85±0.69 and 1.66±0.81, and during the recovery were 1.33±0.57 and 1.25±0.5, in the ondansetron and propofol groups, respectively (p=0.65) (p=0.84).
Based on the results of this study, ondansetron and propofol at doses lower than the hypnotic dose were well tolerated. Considering the effect of both drugs on the treatment of itch caused by intrathecal fentanyl, both of them can be used clinically.

Chronic kidney disease in addition to kidney involvement may cause abnormalities in various systems of the body, in which liver disorders are one of the most commonly encountered disorders. Failure to identify some of these disorders can cause a serious problem in transolant patient. This study was performed to determine the frequency and type of abnormal liver ultrasound findings in renal transplant patients.
In this cross-sectional study, recorded data of 480 kidney failure patients who had received kidney transplant from brain death donors during the last 6 years in three Mashhad hospitals were investigated. Ultrasonography was considered before the transplant and abnormal liver findings were recorded in a checklist and were assesed.
FINDINGS: The mean age was 39.07±12.67 years of which 52.70% were male and 42.30% were female. Liver disorders were observed in 13.12% of patients. The highest prevalence was related to fatty liver grade I (2.5%), grade II (1.46%), gallstone (1.25%) and liver cysts (1.25%).
The results of the study showed that liver asymptomatic disorders in renal transplant patients have significant prevalence and because some of these disorders require treatment before transplantation, enough attention to screening before transplantation can help to prevent post-transplant complications.

Nasal septum deviation (NSD) is one of the leading causes of chronic otitis media and pneumatization of mastoid air cells. In this study, the effect of NSD on pneumatization of mastoid cells and the relationship between NSD and chronic otitis media were investigated using CT scan. In this cross-sectional study, 75 paranasal sinus CT scans with NSD and mastoid view were investigated. Patients were divided into three groups based on the severity of NSD: mild (deviation less than 9 degrees, 25 patients), moderate (deviation from 9 to 15 degrees, 25 patients) and severe (deviation equal to or greater than 15 degrees, 25 patients). Chronic otitis media is defined as the presence of bone destruction or sclerosis accompanied by mass fluid or structural changes in temporal bone air cells. The pneumatization of mastoid cells was determined visually and as formation of mastoid air cells. There was no significant difference in the frequency of pneumatization of mastoid cells between mild (25 patients, 100%), moderate (25 patients, 100%) and severe (23 patients, 92%) nasal septum deviation (p = 0.128). However, the prevalence of chronic otitis media was significantly higher in severe NSD (13 patients, 52%) compared to mild (4 patients, 16%) and moderate (9 patients, 36%) NSD (p = 0.028) The results of the study showed that the severity of NSD does not have an effect on pneumatization of mastoid cells, but severe NSD increases the frequency of otitis media Nasal septum deviation (NSD) is one of the leading causes of chronic otitis media and pneumatization of mastoid air cells.

Due to bacterial resistance to antibiotics, new antibacterial agents is essential. In Persian medicine Fennel (Fuenoculum vulgare Mill.) and Ajwain (Carum copticum (L.) Benth. & Hook.f.) are recommended for the treatment of some infections. In this research, bacteriostatic and bactericidal effects of aqueous and hydroalcoholic extracts of fennel and Ajwain on E. coli were investigated. In an in-vitro study 30 clinical isolates of urine culture of children with urinary tract infection from Amirkola Pediatric Hospital in Babol and a standard sample were used. Antibacterial effects of 4 grouos including aqueous and hydroalcoholic extracts of fennel and Ajwain by measuring the diameter of the inhibition zone using disc diffusion (concentrations 16, 32, 64, 128, 256 and 512 mg/disc) and determination of Minimum Inhibitory Concentrations (MIC) and Minimum Bactericidal Concentration (MBC) with Microdilution method was compared with Gentamicin (30mg/disc) as a positive control
FINDINGS: There was no significant difference in inhibition zone with Gentamicin at concentrations of 64, 128, 256, and 512 mg/disc in standard and clinical samples. At concentrations of 16 and 32, Gentamicin was significantly better. The extract of 512 mg/disc (12.93±2.66) of hydroalcoholic extract of Carum copticum was significantly better than 256 mg/disc (9.53±1) (p=0.002). The MIC and MBC for standard samples were 4 and 8, respectively, and for clinical samples 3.83±2.36 and 5.8 mg / ml, respectively. Other extracts were not able to inhibit the growth of Escherichia coli.

Pseudomonas aeruginosa is considered as one of the important causes of urinary infections in hospitals. The aim of the current study is the genetic typing for the number of bacterial strains isolated from patients using MLVA technique.
In this study, 70 isolates were collected from different hospitals located in Tehran city. First, DNA extraction was conducted for genotyping analysis by MLVA method. Subsequently, VNTR sequences located in several genes of bacterial genomes such as MS-214, MS-215, MS-217, MS-222, MS-223, MS-142 and MS-173 were amplified by specific primers using PCR technique. After confirming the PCR amplification using electrophoresis and visualization of their bonds on agarose gel, relationship evolutionary graph for the different strains was constructed based on MLVA technique.
FINDINGS: After the electrophoresis and determination of VNTR copy-numbers, 70 strains were classified as 36 types. The genetic evolutionary tree was also constructed based on VNTRs Data. According to the results, PCR products of 70 strains visualized by electrophoresis are divided to 39 types based on VNTR analysis. Evolution tree and MSR algorithm was also constructed for all 70 clinical isolates. According to the MST algorithm, 70 clinical strains divided into 11 clonal complexes which these criteria is interpreted as genetic distance based on the difference of VNTR copy numbers for each group
The present study showed that MLVA could be helpful for typing clinical strains of P. aeruginosa. The results also showed that this method had great potential to differentiate those strains with high phenotypic similarity.

Acne vulgaris is one of the most common skin diseases that imposes too much mental pressure and high costs on patients. The existing treatments have low efficacy and include antibiotics and anti-inflammatory drugs, which have many complications due to the chronic nature of the disease, especially at young age, including antibiotic resistance and allergic reactions. For this reason, one of the new therapeutic approaches is the use of a vaccine with the help of the bacterium or its components. The aim of this study is to produce nanoparticles carrying the recombinant CAMP – Sialidase protein as a new chimeric antigen to be used in acne vaccine.
To express the recombinant CAMP – Sialidase protein, E. coli BL21 DE3 was used as the host. Purification of protein was done through combined urea/imidazole method and using a nickel-nitroacetic acid column. The recombinant protein was confirmed using Western Blotting by Anti – Histidine Antibody. Then, the loaded nanoparticles were prepared by recombinant protein using ionic gelation technique and tripolyphosphate. Finally, the size and zeta potential of the nanoparticles were determined by the DLS device.
FINDINGS: The recombinant CAMP – Sialidase protein was confirmed after expression and purification. The size and zeta potential of nanoparticles containing recombinant CAMP – Sialidase protein at a concentration of 0.6 mg / ml were determined to be 80 nm and mV, respectively, using the DLS device. The loading rate of the protein in the nanoparticles was found to be 88%.
The results show that the recombinant protein is expressed completely and is successfully encapsulated in the chitosan nanoparticles.

Kangaroo skin contact is an important factor in breastfeeding. However, in contrast to abdominal contact, it is considered timely. Therefore, while shortening the contact time, this study aims at comparing the effects of short abdominal skin-to-skin contact and Kangaroo skin contact on successful breastfeeding.
This clinical trial study was conducted among pregnant women in maternity hospitals of Torbat Heydarieh in 2015. Sixty-eight primigravida women with term pregnancy and aged 18-40 years were selected through convenience sampling and were divided into two groups of intervention (Kangaroo skin contact) and control (abdominal skin contact). Questionnaires about demographic, fertility and medical data were completed for both groups. Infants with 8-10 Apgar and birth weight of 2500 – 4000 g were exposed to Kangaroo skin and abdominal skin contact for 5-10 minutes. After delivery, The Infant Breastfeeding Assessment Tool (IBFAT) was completed and the mean values of feeding desire, searching, latch on and sucking pattern were analyzed (IRCT: 2014090419039N1).
FINDINGS: The mean feeding desire in the intervention group was 2.63±0.6 and in the control group was 2.61 ± 0.6, searching was 2.76±0.43 and 2.73±0.44, latch on was 2.76±0.43 and 2.79±0.41, sucking pattern was 2.82 ± 0.54 and 2.64 ± 0.64, and total score was 11.84 ± 5.10 and 10.79 ± 1.82, respectively, indicating no significant difference in any of the dimensions.
The results of the study showed that short abdominal skin-to-skin contact and Kangaroo skin contact did not differ significantly regarding their effect on initiation of successful breastfeeding.
