 Indirect inguinal hernias in children are due to the opening of the vaginal process and the entry of viscera into it. We conducted this study to compare the rate of complications and recurrence after open and laparoscopic hernia surgery.

 This case-control study included the patients who underwent surgery by laparoscopic and open methods from 2018 to 2020. The study data were extracted from a checklist based on sex, age, infection rate, side effect, hydrocele rate, scar length, testicular swelling rate, and recurrence rate.

 A total of 261 patients were examined. The results showed a statistically significant difference between the time of surgery in both surgical methods (Z=-9.903, P<0.001). Also, there is a significant statistical relationship between recurrence and surgical procedure (P=0.021). None of the patients in the study had an infection, hydrocele, or testicular swelling after surgery.

Both methods are safe and can be selected according to the patient's condition. It is recommended that further clinical studies be performed to evaluate and compare these two surgical procedures.

The study aim was evaluation of cilostazol effects on results of balloon angioplasty for infrapopliteal artery disease

This randomized controlled clinical trial study was performed on 50 patients undergoing below the knee balloon angioplasty . Patients were randomly assigned into two groups of plavix alone (Group A) and plavix and cilostazol (Group B) and during the 3 month period , limb salvage , need for endovascular re-treatment , improvement of clinical symptoms and incidence of adverse effects were compared

There was no significant difference between the two groups in terms of demographic and clinical characteristics (P >0.05). Significant improvement of symptoms were observed in group B including improvement of rest pain and intermittent claudication within 3 months after treatment (P <0.05). Need for surgical intervention in group A was higher than group B in three months after treatment but there was no significant difference (P >0.05). None of the patients had reported heart failure within three months of treatment.

Although cilostazol administration after below the knee balloon angioplasty in patients with lower limb ischemia has a positive effect on improvement of symptoms such as improvement of rest pain and intermittent claudication But cilostazol did not show a positive effect on limb salvage, ischemic wound healing, and need for reintervention. The results of this study also showed that there was no significant difference in cilostazol users with cardiac complications and gastrointestinal bleeding.

In many patients with ulcerative colitis,control of the disease is possible through medical methods, but in some cases,surgery is indicated.So far,no comprehensive study on the consequences of surgery in children with ulcerative colitis has been published in Iran. present study was conducted for the same purpose.

All children with ulcerative colitis admitted in Mofid Children Hospital with indication for surgery for ten years were included in the study.Information on demographic characteristics,surgical indications, duration of medical treatment,type of surgical procedure,complications of surgery, were evaluated.

21patients who underwent surgery during these years were included in the study. The mean age of patients was 11.12 ± 5.65 years. 42.9% were male. In terms of surgical indications, anemia in 100%, Intestinal bleeding in 33.3%, FTT in 14.3%, recurrent defecation in 9.5% and severe colic abdominal pain in14.3%.In terms of early surgical complications,intestinal perforation in4.8%, peritonitis 4.8%,wound infection23.8%, pelvic abscesses14.3%, deep vein thrombosis4.8%,intestinal obstruction9.5%, Pouchitis 9.5% and anal fissure 4.8% were reported.23.8% of patients underwent redo laparotomy for improvement surgical complications.The mean follow-up period of patients in terms of surgical outcomes was 6.79 ± 4.24years. During this period, improvement in gastrointestinal function was reported in 100% of patients. Long-term complications of surgery include , delayed fistulas were reported in 23.8% of cases. Fecal incontinence was reported at 4.8%. Long-term complication-free survival at 5 and 10 years after surgery was estimated to be 92.3% and 56.4%, respectively.

Surgical treatment in children with ulcerative colitis,candidate for surgery,accompanies with favorable outcomes and correctable short and long-term complications.

Parkinson’s disease (PD) is a common neurodegenerative disease characterized by progressive loss of midbrain dopaminergic neurons with multifactorial etiologies including age, genetic and environmental factors. The current treatments of the disorder only help reduce symptoms but not stop the disease progression. Morin has been shown to exert neuroprotective and anti-oxidant effects in different models of neurodegenerative diseases. This study aims to investigate the effects of morin on pseudo-parkinsonism induced by perphenazine in rats.

In an experimental study 40 male rats (weight range: 160-200 g) were randomly divided into 5 equal groups (n= 8). In group 1 (Reutononcy 3 mg/kg 48h and in 19 days) group 2 LDOPA (10mg/kg 48h 19days) group 3 (Reutcnonc 3mg/kg 48 h cinamicacid 50mg/kg 48h) group 4 (Reutcnonc 3mg/kg 48h and cinaminacid 100mg/kg 48h) group 5 (Reutcnonc 3mg/kg 48h and cinaminacid 200mg/kg 48h) in 19 days.In all groups The muscle stiffness, using Morpurgo method, rate of catalepsy using Rcaring test, and the amount of Malondialdehyde were avaluoted.

The results of study reported the effectiveness of cinamicacid on improving muscle stiffness and muscle weakness, which it was dose dependent, so that cinamicacid at higher doses was more effective in improving these two complications. Moreover, the results reported the effect of different doses of cinamicacid on the reduction of MDA.

In order to better understand the effect of facial patterns on smile attractiveness,the present study was conducted to determine the relationship between facial index and 3 characteristics of smile,namely gingival display, dental show and smile index in 20-35 years old in Ahvaz in 1399.

The statistical population of this analytical epidemiological study included 96 people (48 females and 48 males).Data were collected using 2photographs of frontal view and close up of smile. Using AutoCAD program, the amount of dental show, gingival display, facial height, facial width, smile width, and distance between lips were measured. Descriptive and analytical statistical tests and Chi-square, paired t-test and ANOVA) were used to analyze the data(P <0.05).

There was no significant difference between the mean of the measurement using two direct methods(direct measurement on the face) and indirect measurement on the digital image(p = 0.458).The facial pattern in men was significantly long face(p<0.001).In terms of gingival display and dental show .the effect of facial and gender index was significant(p <0.001).In terms of smile index, the effect of gender was not significant but the effect of facial index was significant(p <0.001).

According to the results, the facial index has an impact on all the affecting factors of the smile.Therefore, it is necessary to pay extra attention to this index in treatment planning and mechanics of orthodontics to obtaine a more attractive smile and for the patient to be more satisfied.Keywords: smile attractiveness, orthodontic treatment, quality of life, malocclusion, facial index

Hyperlordosis is one of the spinal abnormalities. The aim of this study was to investigate the effect of fatigue caused by strenuous running on static and dynamic balance in women with hyperlordosis.

In the present quasi-experimental study, 30 women with lumbar spine curvature greater than 40 degrees were included in the experimental control groups. To measure lumbar lordosis from a flexible ruler and to assess static and dynamic balance, displacement changes and center of pressure (COP) distance, with the eyes open on a hard surface using a biodex device in two pre-fatigue conditions (3 repetitions) and after fatigue (3 repetitions) were performed. The experimental group was affected only by the independent variable of muscle fatigue. Simon test was used to perform the fatigue program to the point of exhaustion.

Fatigue due to running to the point of exhaustion had a significant effect on static and dynamic balance (COP displacement). Fatigue with Simon protocol in the difficult directions of dynamic balance test (anterior, anterior-external and external) compared to before the fatigue protocol had a significant difference in dynamic balance on the subjects.

According to the results, it can be said that fatigue reduces balance in women with lumbar hyperlordosis by reducing postural control.

Most digital imaging systems today offer a variety of image processing techniques. Due to the importance of the accuracy of this imaging and its widespread use in this study we investigate the effect of contrast change in the diagnosis of vertical root fracture in conventional digital radiography.

In this in vitro study 24 human single-rooted teeth induced vertical root fracture with underwent variable refrigerant flow (Vrf). Digital images were prepared before and after inductionvrf. Images with three low, medium and high contrasts were examined by two radiologists.Data were tested using kappa and MacNemar tests in SPSS software. Overall accuracy was calculated using Roc curve analyzes.

The highest sensitivity specificity and overall accuracy are related to images with moderate contrast (95.83%, 100% and 98% in the first observer and 100%, 100% and 100% in the second observer, respectively). In cases of low and high contrast to detect vertical root fracture, there is no statistically significant difference with reality (P<0/001).

Medium contrast can be used as a processing filter in the detection of vertical root fractures.

Chronic periodontitis is one of the most common periodontal diseases. During pregnancy, changes in gingival tissue and biomarkers occur due to changes in hormone levels. Interleukin-6 is a pro-inflammatory factor, as pregnancy and periodontitis can cause changes in biomarkers, therefore in this study, the status of pregnancy and periodontitis was evaluated and a comparison of salivary biomarker changes of interleukin 6 was performed by ELISA method in the evaluated groups.

This study was a case-control study that included 80 women consisting of 40 women with generalized chronic periodontitis and 40 women without periodontal disease that in both pregnant and non-pregnant groups, the level of salivary biomarker interleukin 6 was evaluated by ELISA. The Kruskal-Wallis and Mann-Whitney U tests were used to analyze the statistical data and a significance limit of P≤0.05 was considered.

The highest salivary concentration of interleukin 6 was related to pregnant women with chronic generalized periodontitis and the lowest was observed in non-pregnant women without periodontal disease. The salivary concentration of interleukin 6 in the groups with periodontal disease was significantly different from the groups without periodontal disease (P = 0.04). Also, salivary concentration in saliva of pregnant women with periodontal disease was statistically significant with pregnant and non-pregnant women without periodontal disease (P <0.05).

Salivary IL6 concentrations increase in groups with periodontal disease and in pregnant women this rate is higher than non-pregnant women.

there are many functional tests for assessment athletes after ACL reconstruction for return to sport. One of the most useful of these tests is LEFT. Isokinetic dynamometry is reliable and good indicator for assessment of the athletes to return to sport. Purpose of this study is regarding the dominant features of isokinetic dynamometry and reliable clinical tests for assessing relationship between isokinetic dynamometry results with LEFT clinical test.Subject and

23 athletes with age mean 25.34±3.71 was passed 12-14 months after their ACL reconstruction voluntarily participated in this study. At the first athletes were assessed for confidence of their ACL health and deformity of their lower limbs. In test stage athletes first complete isokinetic dynamometry tests and then perform LEFT test.

the results of the study showed that there is no correlation between isokinetic parameters asymmetry include: H/Q ratio, knee extensor and flexor peak torque, time to extensor and flexor peak torque, time of doing dynamometry tests in flexion and extension and also total work that were done in flexion and extension in 60, 180, 240 degrees per seconds speeds and LEFT test time performance.

time of doing LEFT test with isokinetic dynamometry parameters have no correlation and LEFT test is not the reliable test for assessment of recurrent injury probability.
