AbstractObjective: The purpose of our study was to determine the level of correlation between histopathologic results after surgery for chronic apical periodontitis and the radiographic and clinical diagnosis. The status of gold standard technique of histologic examination was evaluated in the diagnosis of apical radiolucency in necrotic teeth.Methods: Out of 154 patients with incorrect root fillings and apical radiolucency included in an endodontic retreatment protocol, 87 patients (108 teeth) were scheduled for apical surgery at 3-6 months control recall. Clinical and radiographic exams were completed prior to surgery and compared to the histological results of apical biopsies. The collected data were statistically analyzed with the SPSS version 20.0 and the Chi-square test was used to determine the associations between clinical and histologic diagnosis. A value of p <0.05 was considered statistically significant.Results: There was a statistically significant difference between the number of cases diagnosed as granulomas or cysts during clinical and radiological evaluation compared to histologic evaluation of tissue samples, with 40.9% to 75.9% and 54.2% to 16.8% respectively (p<0.05).Conclusions: The final diagnosis was obtained only after histologic examination of apical tissue samples, which means that the observations made based on radiologic investigations must be confirmed by biopsy.

We have investigated prospectively the diagnostic accuracy, specialist satisfaction and patient–specialist rapport of a low-cost audio-visual link between a junior doctor with a patient and a consultant rheumatologist. Using a telephone link and subsequently a video-phone link, 20 patients, with various rheumatological problems, were presented by a junior doctor to the consultant rheumatologist for provisional diagnosis. All patients were then seen face to face by the consultant, when a final diagnosis was made. An independent consultant rheumatologist made a ‘gold standard’ diagnosis. Thirty-five per cent of diagnoses were made correctly over the telephone and 40% over the video-phone – there was no significant difference in the diagnostic accuracy between these two methods of communication. Rapport over the video-phone was universally poor. Where it was important, clinical signs could not be visualized over the video-phone and in more than 85% of cases small joint swellings could not be seen clearly.

<p>This research aimed to investigate the status quo of critical pedagogy in Iran. It focused on examining language teachers’ stances on implementing the principles of critical pedagogy in their classrooms. Also, of particular interest was the study of gender difference in practicing critical pedagogy in language institutes in Iran. At first, the Critical Pedagogy Implementation Inventory, developed by Mozaffari (2011), was administered to 116 instructors teaching at language institutes to collect the required quantitative data. In the second phase of the study, forty-six of the participants were interviewed to gather some complementary qualitative data. The researchers utilized descriptive statistics, factor analysis, Cronbach’s Alpha, chi-square, and independent samples T-test for the quantitative phase of the study, and techniques based on grounded theory in the qualitative phase. Data analysis revealed that the majority of language teachers were in favor of practicing critical pedagogy in their classrooms. However, it was found that critical pedagogy is not efficiently practiced in Iranian educational contexts and even the teachers who advocated the principles of critical pedagogy had an almost average score on the Critical Pedagogy Implementation Inventory. In fact, the teachers claimed that there were some barriers to practicing critical pedagogy in Iran. The top-down educational system, prescriptive approaches to supervision, class size, learners’ expectations, conventional teacher-student relationships, and their traditionally-defined roles were among the main hurdles that impeded an appropriate implementation of critical pedagogy in classrooms. Further investigation also revealed that there was a significant difference between male and female teachers’ stances on practicing critical pedagogy. It was revealed that female instructors tended to be more positively immersed in such implementation.</p><p> </p><p>Keywords: critical pedagogy (CP), educational contexts, foreign language teachers, prescriptive supervision</p><p><strong> </strong></p>

AIM: This study aimed at assessing the trends of publications of Indian Endodontists in the field of rotary Endodontics in the PubMed database from 2000-2017. METHODS: The date of publication was set from 1st January 2000 to 31st December 2017, wherein keywords entered in the advanced search were “Indian” AND “Dental” AND “Rotary Endodontics”. From the collected articles the following criteria were noted: year of publication, the name of the journal, status of the journal, name of the first author, state of origin and the rotary Endodontic file system used. RESULTS: All data was subjected for statistical analysis by SPSS software version 16. The data were subjected to chi-square test, and a statistically significant difference (p < 0.001) was obtained in the inter-6 yearly interval starting from 2000-2017; in the status of the journal; the state of origin and in the generation of rotary files which were published during the study period. CONCLUSION: The plethora of publications by Indian Conservative Dentists and Endodontists is on the rise, and with the advent of better technology a greater interest in the mechanics and properties of these rotary file systems has invoked greater research work.

Background Computed tomography (CT)-guided biopsy is emerging as a preferred method for obtaining tissue samples from retroperitoneal lesions due to clear visualization of needle and vessels. Purpose To assess diagnostic yield and safety of CT-guided biopsy of retroperitoneal lesions and compare CT findings in different disease categories. Material and Methods This retrospective analytical study included 86 patients with retroperitoneal lesions who underwent CT-guided biopsy from December 2010 to March 2020. All procedures were performed with co-axial technique and multiple cores were obtained and subjected to histopathology. Additional tests like immunohistochemistry or microbiological analysis were done depending on clinical suspicion. Diagnostic yield calculation and comparison of imaging findings was done by one-way ANOVA, chi-square, and Fisher’s exact tests. Results CT-guided biopsy was technically successful in all cases with a diagnostic yield of 91.9%. Minor complications in the form of small hematomas were seen in two patients. Major disease categories on final diagnosis were lymphoma, tuberculosis, and metastases. A variety of malignant and benign soft-tissue neoplasms were also noted less commonly. With help of immunohistochemistry, lymphoma subtype was established in 88.8% of cases. Addition of microbiological tests like the GeneXpert assay helped in the diagnosis of tuberculosis in some cases. A mass-like appearance and vascular encasement was common in metastatic group and lymphoma. Conclusion Percutaneous CT-guided biopsy is a safe method for the sampling of retroperitoneal lesions with high diagnostic yield. Imaging findings are mostly overlapping; however, some features are more common in a particular disease condition.

Social pedagogy offers a wide multidisciplinary range to prevent and tackle youth unemployment. In this paper, we want to broaden the knowledge for social pedagogues in the areas of young people in the labour market and youth unemployment. The aim of the research is to identify the experience of respondents in the labour market in the district of Ruzomberok. It is a district in Slovakia far from the capital and regional centres. Most of the district´s inhabitants live in villages, fewer inhabitants in a town of Ružomberok. We conducted a questionnaire survey of 100 respondents. There are 50 young people up to 24 years old, who are currently active in the labour market. Furthermore, there are persons unemployed, registered at the Office of Labour, Social Affairs and Family in Ružomberok, with an age limit of up to 24 years, representing the same number of 50 respondents. We explored the social context; we set two hypotheses: There is a statistically significant difference in the status of the labour market with respect to the respondents' residence. There is a statistically significant difference in the status of the labour market relative to the gender of respondents. To verify the hypotheses, we used the Chi-Square-2 variable test. The hypotheses were not confirmed.

Diaper dermatitis is the most common dermatological disease of infancy, which occurs and caused by the combined effect of irritants such as diaper, urine and faces. In this study, we intend to evaluate the effect of breast milk on the healing of diaper dermatitis. This study was a clinical trial of 30 infants between 0-12 months of age that were suffering from diaper dermatitis and referred to the Health Centers in Tehran, Iran. The subjects were selected by open study. Infants were divided into two matched groups: case and control. Datagathering tools were the questionnaire that contained two parts: the demographic characteristics of infants and the status of care and condition of the lesion. Data analysis was performed using SPSS/18 software and Mann-Whitney and Chi-Square tests were used. The findings revealed a significant difference between the case and control groups in the number and lesion score of the rashes at the first and third day (P=0.013, P=0.005), these differences were more significant at the fifth day (P=0.004, P=0.001). Because of positive effects of breast milk on healing of diaper dermatitis, it is proposed that educational programs in health centers should be considered by health officials, and the managers would play a key role in increasing knowledge behavior changes in mothers.

Purpose The aims of this study were to characterize hearing symptoms, habits, and sound pressure levels (SPLs) of personal audio system (PAS) used by young adults; estimate the risk of developing hearing loss and assess whether instructions given to users led to behavioral changes; and propose recommendations for PAS users. Method A cross-sectional study was performed in 50 subjects with normal hearing. Procedures included questionnaire and measurement of PAS SPLs (real ear and manikin) through the users' own headphones and devices while they listened to four songs. After 1 year, 30 subjects answered questions about their usage habits. For the statistical analysis, one-way analysis of variance, Tukey's post hoc test, Lin and Spearman coefficients, the chi-square test, and logistic regression were used. Results Most subjects listened to music every day, usually in noisy environments. Sixty percent of the subjects reported hearing symptoms after using a PAS. Substantial variability in the equivalent music listening level (Leq) was noted ( M = 84.7 dBA; min = 65.1 dBA, max = 97.5 dBA). A significant difference was found only in the 4-kHz band when comparing the real-ear and manikin techniques. Based on the Leq, 38% of the individuals exceeded the maximum daily time allowance. Comparison of the subjects according to the maximum allowed daily exposure time revealed a higher number of hearing complaints from people with greater exposure. After 1 year, 43% of the subjects reduced their usage time, and 70% reduced the volume. A volume not exceeding 80% was recommended, and at this volume, the maximum usage time should be 160 min. Conclusions The habit of listening to music at high intensities on a daily basis seems to cause hearing symptoms, even in individuals with normal hearing. The real-ear and manikin techniques produced similar results. Providing instructions on this topic combined with measuring PAS SPLs may be an appropriate strategy for raising the awareness of people who are at risk.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Laparoscopic Hemicolectomy

Összefoglaló. Bevezetés: A laparoszkópia térhódítása a jobb oldali colon műtéteknél is nyilvánvaló. Ma legtöbb helyen a laparoszkóposan asszisztált jobb oldali hemikolektómia extrakorporális anasztomózissal a gold standard. A morbiditás randomizált vizsgálatok alapján még 30% körüli. A technikai fejlődés lehetővé tette az intrakorporális anasztomózist. Célkitűzés: Retrospektív módon elemezni rosszindulatú jobb oldali vastagbéldaganat miatt végzett laparoszkópos hemikolektómiák rövid távú eredményeit a két módszer összehasonlításával. Eredmények: 2018. 01. 01. – 2019. 12. 31. között 184 jobb oldali hemikolektómiát végeztünk, ezek közül 122 történt malignus betegség miatt. 51 esetben nyitott és 71 esetben laparoszkópos műtét történt. 37 férfi (átlagéletkor: 70,59 év) és 34 nő (átlagéletkor: 72,14 év) volt. 50 esetben extrakorporális (EA) és 21 esetben pedig intrakorporális anasztomózist (IA) végeztünk. Az EA csoportban 18, míg az IA csoportban 3 szövődmény alakult ki 30 napon belül (p = 0,067). Az EA csoportból 3, az IA csoportból 1 beteget veszítettünk el 30 napon belül (p = 0,66). Az átlagos ápolási idő az EA csoportban 9,48 (5–32) nap, míg az IA csoportban 6,52 (4–19) nap volt (p = 0,001) a szövődményes esetekkel együtt. A szövődményes esetek nélkül az EA csoportban 6,35 (5–10) nap, az IA csoportban pedig 5,55 (4–8) napnak bizonyult (p = 0,09). A műtéti idő pedig az EA csoportban 147 (90–240) perc, az IA csoportban pedig 146,47 (90–265) perc volt (p = 0,11). Konklúzió: Az irodalommal összhangban azt találtuk, hogy IA esetén kevesebb a szövődmény, ezzel is összefüggésben rövidebb az átlagos ápolási idő, és a műtéti időt tekintve nincs szignifikáns különbség. Ezeket figyelembe véve az intrakorporális anasztomózis javasolható jobb oldali laparoszkópos hemikolektómia esetén. Summary. Introduction: Laparoscopy became evident for right-sided colon surgery too. Today the laparoscopic-assisted right-hemicolectomy is the gold standard with extracorporeal anastomosis. Morbidity according to randomized trials is still approximately 30%. The development of the surgical technique resulted in the creation of intracorporeal anastomosis. Our aim was to compare the short-term results of the two methods. Aim: To analyse the short-term results of right-sided hemicolectomy that were performed due to malignant tumours with the comparison of the two methods. Results: A cohort of 184 right-sided hemicolectomy were performed from 01.01.2018 to 31.12.2019 from which 122 were operated on because of a malignant disease. 51 open and 71 laparoscopic operations were performed. The average age of 37 men and 34 women were 70.59 and 72.14 years, respectively. 50 patients underwent extracorporeal (EA) anastomosis and 21 intracorporeal (IA) anastomosis. Within 30 days the number of complications were 18 in the EA group and 3 in the IA group (p = 0.067). 3 from the EA group and 1 from IA group died within 30 days (p = 0.66). The average length of stay were 9.48 days in the EA group and 6.52 days in the IA group together with the complicated cases (p = 0.001) while 6.35 days and 5.55 days without the complicated cases (p = 0.09). The average duration of operation was 147 minutes in the EA and 146.47 minutes in the IA group (p = 0.11). Conclusion: We found concordance with the literature that there are fewer complications in case of IA which might be related to shorter length of stay. There is no significant difference between the surgical times. Bearing these facts in mind, IA might be suggested for right- sided laparoscopic hemicolectomy.
