Based on the adaptive algorithm model, this paper proposes two special model structures of randomized fusion and an optimized convolution kernel and uses it for image recognition. It combined with the adaptive algorithm model image-guided electroacupuncture combined with a continuous femoral nerve block to prevent deep vein thrombosis after total knee replacement. 200 patients after total knee replacement were randomly divided into 4 groups. We observe the incidence of postoperative lower limb deep vein thrombosis, platelet count before and after surgery. Electroacupuncture combined with continuous femoral nerve block can reduce the incidence and has obvious advantages in multi-mode prevention. The effective analgesia provided by electroacupuncture combined with continuous femoral nerve block can not only relieve postoperative pain. It enabled patients to train joint activities and lower limb muscle strength as soon as possible, which is conducive to postoperative functional recovery, but also reduces the body stress response triggered by pain and the hypercoagulable state. At the same time, electroacupuncture stimulation of acupuncture points can reduce the inflammatory edema associated with surgery, improve blood circulation at the surgical site and activate the body's anticoagulation mechanism. It provides new ideas and references for formulating multi-mode prevention and control strategies. To review the use, care, and fitting of pessaries. Women requiring the use of vaginal pessaries for pelvic organ prolapse and/or stress urinary incontinence. Use may also be indicated for women with certain pregnancy-related clinical scenarios, including incarcerated uterus. Pessaries are an option for women presenting with prolapse and/or stress urinary incontinence. In addition, certain types of pessaries can be considered for patients with cervical insufficiency or incarcerated uterus. Most women with prolapse or stress urinary incontinence can be successfully fitted with a pessary and experience excellent symptom relief, high satisfaction rates, and minimal complications. Women with pelvic organ prolapse and/or stress urinary incontinence may choose to use a pessary to manage their symptoms rather than surgery or while waiting for surgery. this website Major complications have been seen only when pessaries are neglected. Minor complications such as vaginal discharge, odour, and erosions can usually be successfully treated. Medline was searched for relevant articles up to December 2018. This is an update of the SOGC technical update published in 2013, which was the first internationally published guidance on pessary use. Subsequently, an Australian guideline on the use of pessaries for the treatment of prolapse was published later in 2013. The authors rated the quality of evidence and strength of recommendations using the approach of the Canadian Task Force on Preventive Health Care (Appendix A).

Les femmes qui ont besoin d'utiliser un pessaire en raison d'un prolapsus génital et/ou d'une incontinence urinaire d'effort. L'utilisation peut être indiquée chez les femmes enceintes dans certains scénarios cliniques liés à la grossesse, dont l'incarcération utérine et le risque de travail préterme liée à l'incompétence du col. Les pessaires constituent une option pour les femmes atteintes d'un prolapsus et/ou d'une incontinence urinaire d'effort. De plus, certains types de pessaires peuvent être utilisés chez des patientes atteintes d'incompétence du col ou d'une incarcération utérine. Il est possible de trouver un pessaire efficace chez la plupart des femmes atteintes d'un prolapsus génital ou d'une incontinence urinaire d'effort de façon à obtenir un excellent soulagement des symptômes, un taux de satisfaction élevé et des complications minimes. BéNéFICES, RISQUES ET COûTS Les femmes atteintes d'un prolapsus génital et/ou d érosions) sont généralement traitables avec succès. DONNéES PROBANTES Des recherches ont été effectuées dans la base de données Medline afin de récupérer les articles pertinents publiés jusqu'en décembre 2018. Le présent document constitue une mise à jour de la mise à jour technique de la SOGC publiée en 2013, laquelle a été la première directive clinique publiée à l'international relativement à l'utilisation des pessaires. Une ligne directrice australienne sur l'utilisation des pessaires pour le traitement du prolapsus a été publiée plus tard en 2013. MéTHODES DE VALIDATION Les auteures ont évalué la qualité des données probantes et la solidité des recommandations au moyen des critères du cadre méthodologique du Groupe d'étude canadien sur les soins de santé préventifs (annexe A). PROFESSIONNELS CONCERNéS Gynécologues, obstétriciens, médecins de famille, physiothérapeutes, résidents et moniteurs cliniques (fellows). DÉCLARATIONS SOMMAIRES RECOMMANDATION. We evaluated the effect of first-visit foam sclerotherapy compared with scheduled treatment for patients with venous ulceration. The study design was a retrospective comparative study. From December 2009 to October 2019, a total of 245 venous ulcers in 214 patients (including recurrent ulcers) were treated at Oulu University Hospital. Of these 245 venous ulcers, 143 were treated with first-visit foam sclerotherapy (group A) and 102 with scheduled treatment (group B). All patients received endovenous ablation (foam sclerotherapy and/or endothermal ablation) and compression therapy to promote venous ulcer healing. The primary outcome was the interval to ulcer healing, determined by Kaplan-Meier survival analysis. The secondary outcomes included the time to ulcer healing from the receipt of referral and ulcer recurrence. The median time to ulcer healing was 2.3months for group A and 3.2months for group B (P= .002). The estimated median ulcer healing times after referral for a first session of endovenous ablation were 2.
