Comparison of the localization of intrauterine adhesions in pregnant and infertile women.

Objective: Intrauterine adhesion (IUA) is the formation of band-shaped fibrotic tissues in the endometrial cavity due to uterine procedures. Most adhesions remain asymptomatic and do not affect fertility or pregnancy conditions. However, they may lead to infertility and pregnancy complications in some women. This study aimed to determine which localization and type of IUA may lead to infertility. Materials and Methods: Seventy-six women with IUA were retrospectively scanned. Thirty-nine women with IUA with uterine factor-related infertility were included in the infertility group. Thirty-seven pregnant women, who had adhesions in the second-trimester ultrasonography and who had a live birth via cesarean section at term, were included in the pregnancy group. The localization of adhesions was determined as the fundus, corpus, isthmus, and cornu. Concerning the type of adhesion, the adhesions were classified as dense- and film-type adhesions. Results: The infertility group was compared with the pregnancy group according to the type and localization of the adhesions. Fundal adhesions were significantly higher in the infertility group compared to the pregnancy group (p<0.05). The isthmic adhesions, however, were more common in the pregnancy group than in the infertility group (p<0.05). Dense-type adhesions were more common in the infertility group than in the pregnancy group (p<0.05). Conclusion: According to the localization and types of adhesions, fundal and dense-type adhesions are among the features of uterine factor-related infertility. However, isthmus-located and film-type adhesions may not cause infertility.

Flipped Classroom in Restorative Dentistry: A First Test Influenced by the Covid-19 Pandemic.

PURPOSE: This study compared the success of dental students with flipped classroom and traditional classroom learning in the restorative dentistry course for the first time at the Faculty of Dentistry of Reims during the 2019- 2020 academic year, influenced by the Covid-19 pandemic, and analysed the correlation with students' feelings. The use of an active learning method can improve success during final exams and increase the motivation of students. MATERIALS AND METHODS: The same teacher taught half of the restorative dentistry course in the flipped classroom approach and the other half as traditional classroom. For the flipped classroom, students were required to complete their homework online before the face-to-face sessions. An exam at the beginning and the end of the semester was conducted with questions about concepts learned with each learning method. Statistical analysis was performed using a t-test at the 0.05 significance level. A questionnaire on satisfaction was conducted to determine the students' opinion on this new learning method in the flipped classroom compared to the traditional classroom. RESULTS: The flipped classroom learning method enabled students to achieve better results on the final exam, with a statistically significant difference compared to traditional classroom learning. Student responses to the satisfaction questionnaire showed an increase in motivation and interest in the lessons and correspond to the increase in exam success. CONCLUSION: The use of the flipped classroom for lower cognitive-level activities is more appreciated by students and yields better results than knowledge acquisition in the traditional classroom.

Knowledge and Opinions of French Dental Students in Operative Dentistry - Management of Deep Carious Lesions.

PURPOSE: A questionnaire survey was recently undertaken among French dental students (FDSs) to investigate their practices, knowledge and opinions in various domains of minimal intervention (MI) in cariology. The present work focuses on management of deep carious lesions (DCLs). MATERIALS AND METHODS: The questionnaire was administered (Spring 2018) to all the fifth-year students of the 16 French dental schools. Descriptive analyses were performed. RESULTS: Among 1370 FDSs (response rate: 84.5%), hardness was the most commonly reported criterion for assessing the endpoint of carious tissue removal (53.9%), followed by firm dentin (40.0%). Regarding FDSs' opinion of leaving carious dentine under a restoration, 41.9% of the respondents agreed that carious tissues should always be removed completely. For an asymptomatic tooth with DCLs and exposed pulp, direct pulp capping was mainly chosen (93.9%). In a clinical case correctly diagnosed as a reversible pulpitis by 79.7% of respondents, nearly half of FDSs chose a one-step complete excavation (48.3%) followed by selective excavation (25.1%), then two-step complete excavation (20.9%) and a minority (5.7%) opted for pulpal therapy (biopulpotomy or endodontic treatment). CONCLUSION: The present results suggest an inadequate dissemination of MI concepts among FDSs towards DCL management. The present results show the need for a harmonisation and a reinforcement of teaching evidence-based MI according to the latest European recommendations.

Knowledge and Opinions of French Dental Students Toward Occlusal and Proximal Restorative Thresholds.

PURPOSE: To investigate the practices, knowledge and opinions of French dental students (FDSs) in various domains of minimal intervention (MI) in cariology. MATERIALS AND METHODS: A cross-sectional, questionnaire-based study was conducted in spring 2018 among all fifth-year French dental students (FDSs) from the 16 French dental schools. The present article focuses on restorative management. Statistical analyses (descriptive, chi-squared) were performed. RESULTS: The response rate was 84.5%. Overall, 97.4% of respondents would have operatively intervened for proximal and 83% for occlusal carious lesions, respectively, while non-or micro-invasive intervention would have been possible. Interestingly, 15% would completely open the occlusal fissures. For both occlusal and proximal lesions requiring a restoration, composite resin was indicated by over 95% of the respondents. In a clinical case, 51.6% of FDSs who rightly diagnosed an enamel carious lesion would operatively intervene. When FDSs could not diagnose the type of carious lesions, a high proportion of invasive actions were also reported (40%). FDSs who read scientific articles were more likely to consider the high importance of not filling sound teeth unnecessarily (p = 0.033). CONCLUSION: FDSs do not have sufficient awareness of MI guidelines regarding occlusal and proximal restorative thresholds. Efforts are required in dental schools to teach FDSs to postpone invasive/restorative strategies to later stages of carious progression. There is a need to strengthen prevention techniques and non-invasive options in the teaching of MI in cariology.

Knowledge and opinions of French dental students related to caries risk assessment and dental sealants (preventive and therapeutic).

OBJECTIVES: A national questionnaire study was performed to document knowledge and opinions of French dental students (FDSs) about minimal intervention (MI) in dentistry especially caries risk assessment (CRA) and dental sealants (DSs). MATERIALS AND METHODS: A questionnaire was administered to the fifth-year dental FDSs (n = 1370) from the 16 French dental schools. Descriptive and statistical analyses were performed. RESULTS: The response rate was 84.5%. A large majority of respondents (87.8%) linked MI with minimally invasive dentistry and 77.4% considered MI as a concept based on prevention. About 80% stated they use CRA in clinical practice, mostly without any specific form. If 80.4% of the respondents would base their treatment plans on CRA, only 55.1% would regularly plan preventive regimens according to individual risk level. However, while 96.6% declared they perform preventive DSs, only 44.3% considered therapeutic sealants as a routine treatment. Although 75.1% of FDSs stated that they had sufficient learning and training related to CRA, 55.9% thought that they need further education about preventive and therapeutic DSs. CONCLUSION: Although FDSs seem to be aware of the importance of CRA and preventive strategies, this study shows the need to harmonize the teaching in cariology according to the latest European recommendations. CLINICAL RELEVANCE: A national questionnaire study showed variability towards knowledge and opinions of FDSs related to MI in cariology. This may impact care provisions in their future professional life showing the urgent need to harmonize the teaching of MI in cariology in France.

Do external female genital measurements affect genital perception and sexual function and orgasm?

OBJECTIVE: To provide baseline data for the anatomy of the external female genitalia and to investigate the correlation between those measurements and sexual function and genital perception. MATERIALS AND METHODS: This prospective cohort study consisted of 208 healthy premenopausal women. The Female Sexual Function index (FSFI) and the Female Genital Self-image scale (FGSIS) questionnaires were administered. Participants were divided into two groups according to their female sexual dysfunction (FSD) status. External genital measurements and anterior and posterior vaginal length were measured. RESULTS: The external female genital measurements were (cm, mean ± standard deviation): clitoral prepuce length 2.05±0.48; clitoral glans length 0.87±0.21; clitoral glans width 0.60±0.15; clitoris to urethra 2.24±0.55; anterior fornix depth 7.75±0.92; posterior fornix depth 9.25±0.75; labia minora width, right 2.12±0.86, left 2.20±0.96. A weak negative correlation was found between total FGSIS scores and clitoral prepuce length (p=0.01, r=-0.17), whereas a weak positive correlation was seen between total FGSIS scores and anterior-posterior vaginal lengths (p=0.04, r=0.13; p=0.02, r=0.15, respectively). No statistically significant difference was found between the genital measurements of participants with FSD (n=82, 39.4%) and those without FSD (n=126, 60.6%), and the total FSFI scores and orgasm subdomain scores. CONCLUSION: The female genital measurements were found to be distributed over a wide range. Although the relationship between genital measurements and genital perception varied, no significant relationship was found between genital measurements and sexual functions or orgasm. These findings suggest that a more cautious approach should be taken towards genital surgeries for cosmetic purposes.

HOXA-10 gene expression in ectopic and eutopic endometrium tissues: Does it differ between fertile and infertile women with endometriosis?

OBJECTIVE: To compare HOXA-10 gene expression in eutopic endometrium samples, between fertile and infertile endometriosis patients and the fertile control cases, and in endometrium and endometrioma specimens, between severe and moderate endometriosis cases. STUDY DESIGN: Prospective clinical study included women without infertility and endometriosis (Group 1); women without infertility but with endometrioma (Group 2); and infertile women with endometrioma (Group 3). In addition, the Group 2 and 3 cohort were assessed based on the findings obtained during laparoscopy, based on the (rAFS) scoring, as women with a rAFS score of 16-40 were evaluated in Group A, whereas those with rAFS score above 40 were considered in Group B. HOXA-10 gene expression was evaluated in both secretory endometrium tissue and endometrioma specimens. RESULTS: Eutopic endometrium samples from group 2 (reference gene = 0,680 vs. target gene = 0,362) and group 3 (reference gene = 0,641 vs. target gene = 0,183) patients revealed a 1,871-fold and 3,509-fold decrease in HOXA-10 gene expression, respectively, as compared to group 1. Endometrial HOXA-10 gene expression was 1,778-fold down-regulated in group 3 women (reference gene = 1,510 vs. target gene = 0,850), when compared to group 2. Both eutopic endometrium and endometrioma tissue samples from severe endometriosis patients revealed 1,259-fold (reference gene = 1,523 vs. target gene = 1,210) and 1,338-fold (reference gene = 1,274 vs. target gene = 0,952), down-regulation in HOXA-10 gene expressions, respectively, as compared to moderate cases. CONCLUSION: Endometrial HOXA-10 gene expression in women with endometriosis is significantly down-regulated than in those without endometriosis. Endometriosis patients with infertility have significantly lower levels of endometrial HOXA-10 gene expression than endometriosis without infertility; thus decreased expression of this gene may, directly or indirectly, be related with the endometriosis-associated infertility. Severe endometriosis cases express, in their both endometrium and endometrioma tissues, significantly lower levels of HOXA-10 gene than moderate endometriosis cases.

Prediction of tumor grade and stage in endometrial carcinoma by preoperative assessment of sonographic endometrial thickness: Is it possible?

OBJECTIVE: To evaluate preopertive accuracy of endometrial thickness for assesment of histologic grade and stage of endometrial carcinoma and also determining a cut-off value for the determination of grade of endometrial carcinoma. MATERIALS AND METHODS: Clinical data of 105 patients who underwent surgical staging with endometrial carcinoma were reviewed retrospectively. Preoperatively endometrial thickness were recorded and correlated with pathologic information. RESULTS: A statistically significant correlation was found in between endometrial thickness and grade of the disease (r=0.746, p=0.001). Besides, no correlation was found between endometrial thickness and stage (r=0.153, p=0.119). The endometrial thickness at 9 mm revealed the optimal sensitivity and specificity (93.33 and 26.2, respectively) for turning through grade1 to grade 2 with 68.2% positive predictive value and 66.7% negative predictive value. We indicated the endometrial thickness at 27 mm as the optimal value with sensitivity and specificity (27.27 and 95.65, respectively) for turning through grade 2 to grade 3 with 66.7% positive predictive value and 77.5% negative predictive value. CONCLUSION: In conlusion, sonographic evaluation of the endometrial thickness is economical, simple and can be used as a prognostic tool for endometrial cancer grading. The operating team may have the chance to get prepared before the operation and may have the chance to inform the patient about the operation.

Small bowel perforation after drawing a blood sample in the femoral artery: a case report.

Small bowel perforation is a rare complication of femoral artery access in cases of femoral hernia. A 48-year-old woman was admitted to the intensive care unit due to pulmonary insufficiency. After a routine femoral arterial blood gas analysis, severe abdominal pain and nausea began. She underwent emergency laparotomy due to acute abdomen. Laparotomy revealed small bowel perforation. Segmental resection and end-to-end anastomosis were performed. The femoral canal was closed using plaque mesh. Special attention is needed during femoral artery access to avoid accidental small bowel perforation. As seen in this case, a careful examination should be done in cases of femoral hernia.
