Guideline No. 447: Diagnosis and Management of Endometrial Polyps.

OBJECTIVE: The primary objective of this clinical practice guideline is to provide gynaecologists with an algorithm and evidence to guide the diagnosis and management of endometrial polyps. TARGET POPULATION: All patients with symptomatic or asymptomatic endometrial polyps. OPTIONS: Options for management of endometrial polyps include expectant, medical, and surgical management. These will depend on symptoms, risks for malignancy, and patient choice. OUTCOMES: Outcomes include resolution of symptoms, histopathological diagnosis, and complete removal of the polyp. BENEFITS, HARMS, AND COSTS: The implementation of this guideline aims to benefit patients with symptomatic or asymptomatic endometrial polyps and provide physicians with an evidence-based approach toward diagnosis and management (including expectant, medical, and surgical management) of polyps. EVIDENCE: The following search terms were entered into PubMed/Medline and Cochrane: endometrial polyps, polyps, endometrial thickening, abnormal uterine bleeding, postmenopausal bleeding, endometrial hyperplasia, endometrial cancer, hormonal therapy, female infertility. All articles were included in the literature search up to 2021 and the following study types were included: randomized controlled trials, meta-analyses, systematic reviews, observational studies, and case reports. Additional publications were identified from the bibliographies of these articles. Only English-language articles were reviewed. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE: Gynaecologists, family physicians, registered nurses, nurse practitioners, medical students, and residents and fellows. TWEETABLE ABSTRACT: Uterine polyps are common and can cause abnormal bleeding, infertility, or bleeding after menopause. If patients don't experience symptoms, treatment is often not necessary. Polyps can be treated with medication but often a surgery will be necessary. SUMMARY STATEMENTS: RECOMMENDATIONS.

Technicity in Canada: A Nationwide Whole-Population Analysis of Temporal Trends and Variation in Minimally Invasive Hysterectomies.

STUDY OBJECTIVE: The objective of our study was to provide a contemporary description of hysterectomy practice and temporal trends in Canada. DESIGN: A national whole-population retrospective analysis of data from the Canadian Institute for Health Information. SETTING: Canada. PATIENTS: All women who underwent hysterectomy for benign indication from April 1, 2007, to March 31, 2017, in Canada. INTERVENTIONS: Hysterectomy. MEASUREMENTS AND MAIN RESULTS: A total of 369 520 hysterectomies were performed in Canada during the 10-year period, during which the hysterectomy rate decreased from 313 to 243 per 100 000 women. The proportion of abdominal hysterectomies decreased (59.5% to 36.9%), laparoscopic hysterectomies increased (10.8% to 38.6%), and vaginal hysterectomies decreased (29.7% to 24.5%), whereas the national technicity index increased from 40.5% to 63.1% (p <.001, all trends). The median length of stay decreased from 3 (interquartile range 2-4) days to 2 (interquartile range 1-3), and the proportion of patients discharged within 24 hours increased from 2.1% to 7.2%. In year 2016-17, women aged 40 to 49 years had significantly increased risk of abdominal hysterectomy compared with women undergoing hysterectomy in other age categories (p <.001). Comparing women with menstrual bleeding disorders, women undergoing hysterectomy for endometriosis (adjusted relative risk [aRR] 1.36; 95% confidence interval [CI], 1.28-1.44) and myomas (aRR 2.01; 95% CI, 1.94-2.08) were at increased risk of abdominal hysterectomy, whereas women undergoing hysterectomy for pelvic organ prolapse and pelvic pain (aRR 1.47; 95% CI, 1.41-1.53) were at decreased risk. Using Ontario as the comparator, Nova Scotia (aRR 1.35; 95% CI, 1.27-1.43), New Brunswick (aRR 1.25; 95% CI, 1.18-1.32]), Manitoba (aRR 1.35; 95% CI, 1.28-1.43), and Newfoundland and Labrador (aRR 1.18; 95% CI, 1.10-1.27) had significantly higher risks of abdominal hysterectomy. In contrast, Saskatchewan (aRR 0.75; 95% CI, 0.74-0.77) and British Columbia (aRR 0.86; 95% CI, 0.85-0.88) had significantly lower risks, whereas Prince Edward Island, Quebec, and Alberta were not significantly different. CONCLUSION: The proportion of minimally invasive hysterectomies for benign indication has increased significantly in Canada. The declining use of vaginal approaches and the variation among provinces are of concern and necessitate further study.

Global Women's Health Education in Canadian Obstetrics and Gynaecology Residency Programs: A Survey of Program Directors and Senior Residents.

OBJECTIVE: To become culturally competent practitioners with the ability to care and advocate for vulnerable populations, residents must be educated in global health priorities. In the field of obstetrics and gynaecology, there is minimal information about global women's health (GWH) education and interest within residency programs. We wished to determine within obstetrics and gynaecology residency programs across Canada: (1) current GWH teaching and support, (2) the importance of GWH to residents and program directors, and (3) the level of interest in a national postgraduate GWH curriculum. METHODS: We conducted an online survey across Canada of obstetrics and gynaecology residency program directors and senior obstetrics and gynaecology residents. RESULTS: Of 297 residents, 101 (34.0%) responded to the survey and 76 (26%) completed the full survey. Eleven of 16 program directors (68.8%) responded and 10/16 (62.5%) provided complete responses. Four of 11 programs (36.4%) had a GWH curriculum, 2/11 (18.2%) had a GWH budget, and 4/11 (36.4%) had a GWH chairperson. Nine of 10 program directors (90%) and 68/79 residents (86.1%) felt that an understanding of GWH issues is important for all Canadian obstetrics and gynaecology trainees. Only 1/10 program directors (10%) and 11/79 residents (13.9%) felt that their program offered sufficient education in these issues. Of residents in programs with a GWH curriculum, 12/19 (63.2%) felt that residents in their program who did not undertake an international elective would still learn about GWH, versus only 9/50 residents (18.0%) in programs without a curriculum (P < 0.001). CONCLUSION: Obstetrics and gynaecology residents and program directors feel that GWH education is important for all trainees and is currently insufficient. There is a high level of interest in a national postgraduate GWH educational module.

Objective: Pour devenir des praticiens compétents sur le plan culturel étant en mesure de prodiguer des soins aux populations vulnérables et de défendre leur cause, les résidents doivent recevoir une formation abordant les priorités de la santé à l'échelle mondiale. Dans le domaine de l'obstétrique-gynécologie, nous ne disposons que de peu de renseignements au sujet de la formation en santé des femmes à l'échelle mondiale (SFEM) qu'offrent les programmes de résidence et de l'intérêt envers ce type de formation que l'on y constate. Nous souhaitions déterminer ce qui suit en ce qui concerne les programmes canadiens de résidence en obstétrique-gynécologie : (1) la situation actuelle pour ce qui est de l'enseignement de la SFEM et du soutien disponible à cet égard; (2) l'importance de la SFEM pour les résidents et les directeurs de programme; et (3) le degré d'intérêt envers un curriculum national de cycle supérieur dans le domaine de la SFEM. Méthodes : Nous avons mené, à l'échelle du Canada, un sondage en ligne auprès des directeurs des programmes de résidence en obstétrique-gynécologie et des résidents de dernière année du domaine. Résultats : Parmi les 297 résidents sollicités, 101 (34,0 %) ont répondu au sondage et 76 (26 %) ont rempli le sondage en entier. Onze des 16 directeurs de programme sollicités (68,8 %) ont répondu et 10/16 (62,5 %) nous ont fourni des réponses complètes. Quatre des 11 programmes (36,4 %) comptaient un curriculum de SFEM, 2/11 (18,2 %) comptaient un budget de SFEM et 4/11 (36,4 %) comptaient un président de la SFEM. Neuf directeurs de programme sur 10 (90 %) et 68 résidents sur 79 (86,1 %) étaient d'avis qu'une compréhension des questions de SFEM est importante pour tous les stagiaires canadiens en obstétrique-gynécologie. Seulement un directeur de programme sur 10 (10 %) et 11 résidents sur 79 (13,9 %) étaient d'avis que leur programme offrait une formation suffisante sur ces questions. Parmi les résidents des programmes comptant un curriculum de SFEM, 12/19 (63,2 %) étaient d'avis que les résidents de leur programme qui n'entreprenaient pas un stage au choix international auraient tout de même l'occasion de se sensibiliser à la SFEM, par comparaison avec seulement neuf des 50 résidents (18,0 %) des programmes ne comptant pas un tel curriculum (P < 0,001). Conclusion : Les résidents et les directeurs de programme du domaine de l'obstétrique-gynécologie estiment que la formation au sujet de la SFEM est importante pour tous les stagiaires et qu'elle est actuellement insuffisante. La mise sur pied d'un module pédagogique national de cycle supérieur en SFEM suscite un vif intérêt.

Neuronal apoptosis does not play an important role in human rabies encephalitis.

It is generally accepted that there are not prominent features of neuronal cell death in rabies encephalitis. However, Hemachudha and coworkers recently reported widespread apoptosis in the central nervous system of several human rabies cases (BMC Infect Dis 5: 104, 2005). In this study we have evaluated morphological features and markers of neuronal apoptosis in postmortem brain tissue from 12 cases of human rabies who died in four different countries. Histopathological analysis, TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling) staining, and immunostaining for cleaved (activated) caspase-3 were performed on paraffin-embedded tissues from the cerebral cortex, hippocampus, and brainstem, and additional regional areas from one of the cases. We did not find morphological evidence of neuronal apoptosis or TUNEL staining in any of the cases of rabies encephalitis. Similarly, immunostained cleaved caspase-3 was not seen in neurons, but prominent staining was observed in microglial processes. We conclude that neuronal apoptosis does not play an important pathogenetic role in human rabies encephalitis.
