- چکیده انگلیسی: Background Some animal studies have reported that Achillea millefolium (A. millefolium) extract can affect intestinal movements in rats. However, no study is available on the effect of A. millefolium on recovery from gastroenteritis in human subjects. Objectives This study aimed to investigate the effect of A. millefolium on recovery from gastroenteritis in patients over 12 years old. Patients and Methods A randomized controlled trial was conducted on 44 patients with gastroenteritis. The patients were randomly assigned to two groups of 22 each. The control group received the usual treatments. In addition to the usual treatments, the intervention group received 0.5 mL/kg of A. millefolium distillate every 8 hours. The duration of recovery was recorded for both groups. Descriptive statistics, Chi-square, Fisher’s exact test, and the t-test were used to compare the two groups. Results The mean duration of recovery in the group receiving A. millefolium distillate was 1.31 ± 0.71 days, while it was 1.86 ± 0.71 days in the control group (P = 0.015). Conclusions Adding A. millefolium distillate to the usual treatment for simple gastroenteritis was effective in shortening the recovery time.

- چکیده:
- چکیده انگلیسی: Background Urinary catheterization is one of the main measures used to treat and care for hospitalized patients. Several complications have been attributed to the presence of latex with routine Foley catheters. Therefore, some studies have recommended that Nelatone catheters be substituted for the ordinary Foley catheters to prevent these complications. Objectives This study aimed to compare the rates of urinary tract infection (UTI) in rabbits catheterized either with Foley or with Nelatone catheters. Materials and Methods A randomized controlled trial was conducted on 60 rabbits that were randomly assigned to three groups of twenty. The first group was catheterized using Nelatone catheter; the second group was catheterized using Foley catheter and the third group was studied without performing any catheterization. After seven days, urine samples were collected using suprapubic aspiration and were sent to the laboratory for culture. Descriptive statistics were calculated. Moreover, chi-square and Fisher’s exact tests were used for data analysis. Results At the end of the study, four 4 cases in the Nelatone group and 12 cases in the Foley group presented with UTI (P = 0.01). No positive urine cultures were found in the control group. Conclusions The Nelatone catheters, compared with the Foley ones, had a lower risk of UTI in the long term use. Verifying this claim by further studies can have an important role in reducing UTIs in patients using urinary catheters.

- چکیده انگلیسی: Background Despite all progresses in surgical science, bleeding caused by traffic accidents is still a challenge for surgeons to save patients’ lives. Therefore, introducing an effective method to control external bleeding is an important research priority. Objectives This study aimed to compare haemostatic effect of zinc chloride and simple suturing to control external bleeding. Materials and Methods In this animal model study, 60 male Wistar rats were used. An incision (two cm in length and half a cm in depth) was made on shaved back of rats. The hemostasis time was measured once using zinc chloride with different concentrations (5%, 10%, 15%, 25%, and 50%) and then using simple suturing. Skin tissue was assessed for pathological changes. Due to abnormal distribution of variables in Kolmogorov-Smirnov test, the data was analyzed using Kruskal-Wallis test Mann-Whitney U tests. Results In all the groups, complete hemostasis occurred. Hemostasis times of different concentrations of zinc chloride were significantly less than that of the control group (P < 0.001). Conclusions Zinc chloride was effective to control external bleeding in rats.

- کلمات کلیدی: Wind Shelter Index,The Effective Distance,Virtual Wind Shelter,Non-Snowy Watershed
- چکیده:
- چکیده انگلیسی: The wind’s effectiveness was compared in different points of a watershed using a quantity called The Wind Shelter Index (WSI). It is necessary to choose a distance called the effective distance in the process of this index calculation. First, the WSI is calculated for different distances, and then the most effective distance is chosen among the different distances. Thus, the WSI corresponding to this distance is determined as the WSI of the region. The current criterion for this purpose (correlation WSI with snow depth) was only usable in snowy places, because it requires measurements of snow depth in different points of the region. According to the wind shelter index usability in some phenomena that are not in snowy areas, the use of this index will be applied. In this study, conducted in the Samsami basin, a new index called “Virtual Wind Shelter index (VWSI)” is introduced that can be used to choose the effective distance of the area applicable in snowy and non-snowy places. It can be seen that using the proposed criterion to select the effective distance doesn’t need to measure snow depth, and this method can be used for non-snow areas. Using the proposed criterion, the WSI corresponding to the 100-meter distance was determined as the WSI of the study area, which was consistent with previous study that was determined by the criterion of correlation of WSI with snow depth in the basin.

- چکیده:
- چکیده انگلیسی: Background and Objective: Anemia is a common manifestation of human immunodeficiency virus (HIV) infection, occurring in approximately 30% of patients with asymptomatic infection and in as many as 75% to 80% of those with AIDS. Anemia has been associated with decreased quality of life and decreased survival. In this study we aimed to determine the prevalence and related factors of anemia in HIV-infected patients. Materials and Methods: A total of 143 HIV positive patients who referred to behavioral disease consulting center in Tehran were screened for anemia. Mild to moderate anemia was defined as hemoglobin (Hb) 8-14g/dl for men and 8-12g/dl for women; severe anemia was defined as Hb less than 8g/dl for both males and females. sociodemographic data were collected using a questionnaire. In all patients, CD4 lymphocytes counting were done by flowcytometry. Results: It was found out that 143 HIV positive patients with a mean age of 37.1+ 2 years were enrolled in our study. The mean Hb level was 13.5 ± 2.1 g/dl. Mild anemia occurred in 46% of subjects while severe anemia was not observed. There was not any significant difference between patients with and without anemia regarding age, gender, stage of the infection, CD4 cells count and concurrent anti-retroviral therapy. We also found significant difference between anemia and risk behaviors for HIV acquisition. Conclusion: Our results showed that mild to moderate anemia was frequent in HIV positive patients but severe anemia was not prevalent in this study population.

- چکیده:
- چکیده انگلیسی: Introduction:
Otitis media with effusion (OME) is prevalent among children in such a way that it is the most common cause of hearing loss and surgery in childhood. Immunoglobulin E (IgE) mediated hypersensitivity has been proposed as a causative factor in the development of OME; however, there has been contrasting data in this regard. Therefore, the present study aimed to detect the possibilities of interconnection.
Materials and Methods:
In this study, 37 OME children were selected as the case group and 52 children were randomly chosen as the control group. Allergic rhinitis prevalence, serum total IgE concentration, serum eosinophil count, and nasal scraping cytology were evaluated in all the children. Furthermore, the skin prick test was performed in the OME group and suspected allergic rhinitis patients in the control group.
Results:
Allergic rhinitis prevalence was notably higher among OME patients than in the control group (P=0.01). There were no remarkable differences in eosinophil counts and serum IgE concentrations in the two groups. Nasal smear eosinophils did not show any significant difference between the two groups; however, Appreciable difference was observed in the allergic rhinitis patients, compared to other OME patients (P=0.004).
Conclusion:
There may be a correlation between allergic rhinitis and development of OME. Therefore, it seems reasonable to examine allergic rhinitis patients for OME.- انتشار مقاله: 26-12-1395

- چکیده انگلیسی: Introduction:
Although the psychological aspects of rhinoplasty have been fully investigated in the medical literature, the religiosity of rhinoplasty candidates has not been taken into consideration. Materials and Methods:
In this cross-sectional study, the religious attitudes of 157 rhinoplasty candidates were compared with those of 74 subjects who had not requested rhinoplasty. A domestic validated reliable questionnaire was completed by all subjects to classify them with respect to religious attitude. Other factors such as age, sex and economic and educational status were also taken into consideration. From the surgeon’s perspective, subjects were put into three categories: subjects who had a relative indication for rhinoplasty (Category.1), subjects with a well-defined nose based on accepted standards of facial aesthetic analysis (Category.2) and finally subjects with a severely deformed nose, such as deviated nose or nasal cleft lip deformity (Category.3). Results:
The mean age among subjects was 28.63 ± 7.05 years, and the majority were female (87%). The two groups of participants (those who did and did not express a desire for rhinoplasty) were analyzed from the point view of age, sex, economic and educational status. The economic and educational status of the two groups did not differ significantly (P>0.05). The religious score showed a significant difference between those who were interested in rhinoplasty (122.75±23.49) and those were not interested (138.78±21.85; P<0.001). Conclusion:
Religion may affect a patient’s decision to undergo rhinoplasty surgery, such that persons with a higher religious attitude tend to undertake it less often. However, individuals with major nasal deformities tend to decide undertake the surgery, irrespective of religious beliefs.

- چکیده انگلیسی: Introduction:
To evaluate the most sensitive symptom to predict early recurrence of nasal polyposis. Prospective longitudinal cohort study. Tertiary university referral center with accredited otorhinolaryngology residency programs.
Materials and Methods:
In this prospective study, we evaluated 62 patients with diffuse nasal polyposis. All patients underwent functional endoscopic sinus surgery. The author-devised questionnaire relating to the four major symptoms of chronic rhinosinusitis were answered by patients at the pre-operative visit and at 1, 3, 6, 12, and 24 months after surgery. Patients were followed up with serial endoscopic examinations, and a computed tomography (CT) scan was performed if indicated.
Results:
All 62 patients (37 male, 25 female) completed the study. The mean age was 41.24 ± 12.47 years. All major symptoms showed significant improvement after surgery (P=0.000); however, the severity of symptoms gradually increased in patients with a recurrence of polyposis, but at different points in time (P= 0.008). Sense of smell was the first symptom to deteriorate in patients with relapse (mean, 6 months) followed by nasal secretion (12 months), obstruction and pain
(24 months). Patients with asthma, Samter’s triad, allergic fungal rhinosinusitis (AFRS) and allergic rhinitis showed symptoms of recurrence sooner than other patients (P<0.05).
Conclusion:
The most sensitive symptom for the early detection of recurrence of nasal polyposis is a decrease in the sense of smell. Nasal obstruction and facial pain were observed in the late stage of relapse when frank polyposis formation was established.- انتشار مقاله: 23-03-1394

- چکیده:
- چکیده انگلیسی: Objective(s): Regulatory T cells, including CD4+CD25+Fox3+ and CD8+CD28- cells play an important role in regulating the balance between immunity and tolerance. Since multiple sclerosis is an inflammatory autoimmune disease, regulatory T cells are considered to be involved in its pathogenesis. In this study, we investigated the circulatory numbers of the two mentioned types of regulatory T cells and also their association with different clinical characteristics in 84 multiple sclerosis patients.
Materials and Methods: 84 patients with multiple sclerosis and 75 normal individuals were studied. Demographic and clinical information of all participants were collected via questionnaire and clinical examination as well as MRI. The peripheral blood frequency of two different subgroups of regulatory T cells (CD4+ CD25+Foxp3+ and CD8+CD28- cells) were analyzed by flow cytometry using anti-human antibodies conjugated with CD4-FITC / CD25-PE/Foxp3-PE-Cy5, CD3-PE/CD8a-PE-Cy5/CD28-FITC.
Results: The frequency of CD4+CD25+Foxp3+ cells in multiple sclerosis patients was significantly less than that in healthy controls (P=0.006) and in mild forms less than that in sever forms (P=0.003). There was not any correlation between the frequency of regulatory T cells and different clinical variables.
Conclusion: Our results showed that the number of CD4+CD25+Foxp3+ cells decreases significantly in multiple sclerosis patients, which probably shows the regulatory role of these cells in multiple sclerosis.- انتشار مقاله: 30-01-1393

- چکیده:
- چکیده انگلیسی: Nowadays, shovels play an important role in production of open pit mines and their failures result in significant production loss and considerable increase in maintenance costs. Therefore, reliability and risk analysis can help to improve production, productivity and reduce production costs. In this study, reliability of electric cable shovel of Chadormalu iron ore mine in Iran was investigated. Failure distribution function of the subsystems whose failure information is available was provided by statistical analysis using EasyFit 5.5, Minitab 18 and the subsystems with low or unavailable failure information which was generated by experts using normal distribution function. Criticality of subsystems was determined using Birnbaum and Fussell–Vesely importance measures reliability. Results showed that reliability of cable shovel has reached to zero after 40 hours and subsystems of crowd gearbox, swing gearbox, lubrication and bucket door are the most critical subsystems.
