Introduction: Demonstration of the access cavity preparation procedures to dental students is challenging due to the limited operating field and detailed nature of the procedures. It is especially difficult to visualize how instruments are functioning inside the pulp space. The aim of this study was to develop and compare two different views of video demonstration in teaching access cavity preparation. Materials and Methods: Two videos of access cavity preparation were filmed, showing occlusal view of a whole tooth (WT) and sagittal view of a sectioned tooth (ST). Using quasirandomization, third year dental students (n=57) were divided into two groups to watch either one of the videos. The perception and performance of both groups were compared using Mann-Whitney U test and Fisher exact test. Results: At baseline, group WT (n=29) and group ST (n=28) were not significantly different in terms of operative scores (p=0.330). After watching the videos, the basic understanding of the theories were similar between both groups. However, ST responded more positively towards the helpfulness of the video in visualizing the inner anatomy of the tooth and in implementing the procedures (p<0.05). ST also completed the exercise within a shorter time (p<0.001). Nevertheless, the quality of the prepared access cavities was not significantly different between groups. Conclusion(s): Using sagittal view of sectioned tooth in video demonstration of access cavity preparation can improve students learning and performance speed. We highly recommend showing the sagittal view of sectioned tooth in video demonstration of access cavity preparation.

Intravesical prostaglandin E2 is effective in the recovery of spontaneous voiding after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. The aim of the study was to compare the effects of intravesical prostaglandin E2 in the prevention of urinary retention after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. STUDY DESIGN: From November 1996 to June 1999 fifty women underwent the Lahodny procedure for moderate/severe cystocele and stress urinary incontinence. Women were randomly assigned to 1 of the 2 study groups: intravesical prostaglandin E2 versus controls. Data obtained were analyzed with the Student t test and the Fisher exact test. RESULTS: Two patients of the treatment group had to be excluded from the study, one because of the wrong measurement of the post-voidal residual volume and another due to a fastidious burning sensation which appeared immediately after prostaglandin instillation and required the suspension of the treatment. No other side effects such as nausea, vomiting, diarrhea or hyperthermia were observed. Patients who underwent the prostaglandin E2 treatment showed a recovery of spontaneous voiding after 7.9&plusmn;6.7 days, whereas this interval was significantly longer in the control group, being 12.9&plusmn;9.7 days (p=0.04, Two tailed Unpaired Student's T test). CONCLUSION: The effectiveness and the low associated morbidity mark the treatment with intravesical prostaglandin E2 useful in the recovery of normal voiding after transvaginal pubocervical fascia reconstruction and short arm sling with the procedure according to Lahodny.

Material and methods. Questionnaire survey for the estimation of the Quality of life was done in 796 students. 419 students of Arkhangelsk State Medical Institute were tested in 1979-1984, including 205 males and 214 females with an average age of 22.2; 203 students of higher educational institutions of Severodvinsk in 1998-2005 including 85 males and 118 females with average age of 18.7; 173 students of M.V. Lomonosov Northern (Arctic) Federal University (Arkhangelsk and Severodvinsk) including 85 males and 88 females with average age of 19.5. Meaningfulness of differences in studied indices is calculated using Fisher’s exact test. Results. The decline in quality of life and lifestyle indices (dissatisfaction with living conditions, food quality, summer holidays) in 1998-2005 is shown in comparison to 1979-1984 period; in 2014-2015 they significantly increased. Nevertheless, no more than half of the respondents (45%-34%-53%) characterize their diet as adequate and regular. Increase in adherence to healthy lifestyle in modern students is noted: relatively large amount of them regularly takes exercises (10%-13%-39%), toughens up (8%-4%-9%), swim a lot in natural bodies of water (20%-15%-23%), never consume alcohol (12% -13% -35% of males 30%-5%-30% of females). However the proportion of smoking students has increased compared to the first stage of research (57%-70%-65% of males and 6%-75%-53% of females), and the proportion of those toughening themselves up regularly doesn’t exceed 9%. An increase in the number of students with no chronic diseases is shown. More students have complaints about precardialgia while complaints about gastrointestinal dysfunction and headaches became less frequent. Majority of the students are satisfied with their lives. Almost half of the respondents noted good mood as a predominant one.

Introduction: Occupational exposure in dentistry is defined as exposing the skin or mucosa to blood, saliva, or infectious discharge of the patient. Dentists are in contact with sharp and high-speed rotary devices that increase the chance of occupational exposure. The purpose of this study was to determine the occupational exposure to blood and saliva of patients in dental students of Shahid Sadoughi University of Medical Sciencesin 2016-2017. Methods: A descriptive analytical study was conducted on 70 senior dental students at the School of Dentistry of Shahid Sadoughi University of Medical Sciences in Yazd, Iran. A standard questionnaire was used for collecting the data. After collecting the data, they were coded and entered into the SPSS 20 software and analyzed using descriptive statistics, Chi-square and Fisher exact test. Results: Based on the results, 49 (70%) of 70 students have been suffered from sharp devices. The skin or mucosa of the 62 students (88.6%) infected with saliva or other body fluids of the patients. Only 15.7% of the injuries were reported with sharp objects and 14.3% of mucosal-skin contamination with blood or saliva. Conclusion: Occupational exposure in dentistry environment is a common problem and many cases, which are related to these subjects were not reported. In order to reduce the risks of this, infection control issues should be taught to dental students. Therefore, occupational exposure management, follow-up centers and guidelines should be established for dental schools.

Abstract The aim of the study was to investigate the effects of the rhGM-CSF gel on third-degree frostbite wounds. Sixty-two patients who had suffered third-degree frostbite on their hand or foot (91 wounds in total) were selected using a convenience sampling method and randomly allocated to two groups: the rhGM-CSF group(31patients,45 frostbite wounds) received the rhGM-CSF gel when wound dressing change daily; however, the control group (31patients, 46 frostbite wounds) received aloe glue. The wound healing time, the score of inflammation about the wound and the positive bacterial culture of wound secretions were used to measure outcomes, respectively. Data were analyzed using SPSS (25.0), Student’s t test or Mann–Whitney U test and chi-square test or Fisher exact test were selected, as appropriate. The healing time of the rhGM-CSF group was (12.2 ± 5.0) days, which was significantly shorter than that of the control group (15.5 ± 4.7) days (P &lt; .0001). The rhGM-CSF group’s wound inflammation scores on the 7th and 14th day of treatment were (0.96 ± 0.21) and (1.88 ± 0.29), respectively, which were better than those of the control group (1.12 ± 0.24) and (1.38 ± 0.15) (both P &lt; .0001). The positive bacterial culture of wound secretions in the rhGM-CSF group was also better than that in the control group on the 3rd, 7th, and 14th day after treatment (P = .027, .004, .030, respectively). According to the results, using rhGM-CSF gel considerably increases the speed of frostbite wounds healing, and have an effect on protecting third-degree frostbite wounds regarding the positive effects. Trial Registration: This trial was registered in the Chinese Clinical Trial Register, ChiCTR1900021299.

Ingestion of probiotics appears to have modest effects on the incidence of viral respiratory infection. The mechanism of these effects is not clear; however, there is evidence from animal models that the probiotic may have an effect on innate immune responses to pathogens. The purpose of this randomised, placebo-controlled study was to determine the effect of administration of Bifidobacterium animalis subspecies lactis Bl-04 on innate and adaptive host responses to experimental rhinovirus challenge. The effect on the response of chemokine (C-X-C motif) ligand 8 (CXCL8) to rhinovirus infection was defined as the primary endpoint for the study. 152 seronegative volunteers who had been supplemented for 28 days, 73 with probiotic and 79 with placebo, were challenged with RV-A39. Supplement or placebo administration was then continued for five days during collection of specimens for assessment of host response, infection, and symptoms. 58 probiotic and 57 placebo-supplemented volunteers met protocol-defined criteria for analysis. Probiotic resulted in higher nasal lavage CXCL8 on day 0 prior to virus challenge (90 vs 58 pg/ml, respectively, P=0.04, ANCOVA). The CXCL8 response to rhinovirus infection in nasal lavage was significantly reduced in the probiotic treated group (P=0.03, ANCOVA). Probiotic was also associated with a reduction in nasal lavage virus titre and the proportion of subjects shedding virus in nasal secretions (76% in the probiotic group, 91% in the placebo group, P=0.04, Fisher Exact test). The administration of probiotic did not influence lower respiratory inflammation (assessed by exhaled nitric oxide), subjective symptom scores, or infection rate. This study demonstrates that ingestion of Bl-04 may have an effect on the baseline state of innate immunity in the nose and on the subsequent response of the human host to rhinovirus infection.

Purpose:To determine prevalence of heel strike in a midsize city marathon, if there is an association between foot-strike classification and race performance, and if there is an association between foot-strike classification and gender.Methods:Foot-strike classification (forefoot, midfoot, heel, or split strike), gender, and rank (position in race) were recorded at the 8.1-km mark for 2112 runners at the 2011 Milwaukee Lakefront Marathon.Results:1991 runners were classified by foot-strike pattern, revealing a heel-strike prevalence of 93.67% (n = 1865). A significant difference between foot-strike classification and performance was found using a Kruskal-Wallis test (P < .0001), with more elite performers being less likely to heel strike. No significant difference between foot-strike classification and gender was found using a Fisher exact test. In addition, subgroup analysis of the 126 non-heel strikers found no significant difference between shoe wear and performance using a Kruskal-Wallis test.Conclusions:The high prevalence of heel striking observed in this study reflects the foot-strike pattern of most mid-distance to long-distance runners and, more important, may predict their injury profile based on the biomechanics of a heel-strike running pattern. This knowledge can help clinicians appropriately diagnose, manage, and train modifications of injured runners.

Introduction: Uterine prolapse is a gynecological problem that women often experience with a prevalence of 50% and is predicted that the next 30 years will increase by 45% as life expectancy increases. Increased degrees of uterine prolapse have an impact on the deterioration of women's quality of life. The uterine prolapse is influenced by several mutually supportive factors. The purpose of this study was to analyze the relationship between these factors to the degree of uterine prolapse.Methods: This research is an observational analytic research with cross sectional approach. The number of samples were 65 patients with uterine prolapse at Policlinic Gynecology RSUD Dr. Soetomo Surabaya from 2015-2017. Sampling was done by consecutive sampling. To find out the significant level, the collected data will be tested with Fisher Exact Test statistic at significance level α = 0,05.Results: The result showed that there was significant difference between degree of uterine prolapse with age factor (p = 0,016) and obesity (p = 0,041). As for the parity factor (p = 0.508) there was no significant difference between the parity factor and the degree of uterine prolapse.Discussion: Age is a major factor affecting the degree of uterine prolapse, weakening of pelvic floor tissue and muscle in elderly women is the main cause. While on the obesity factor, there is no data to support that obesity is related to the degree of uterine prolapse because the trend indicates that the majority of patients are not obese. In contrast the parity factor, although according to the statistical test there is no difference to the degree of uterine prolapse, the trend shows that parity leads to increased incidence of uterine prolapse itself.Conclusion: Age is a factor that affects the degree of uterine prolapse.
