Objectives
This study aims to assess the effectiveness of an intracanal composite anchorage to replace conventionally cemented titanium or bonded glass fibre posts.Materials and methods
Post space preparation was performed up to depths of 6 mm (groups 1 and 2) and 3 mm (group 3) in root filled mandibular premolars. In group 1, titanium posts were cemented with zinc phosphate cement. Glass fibre posts were adhesively cemented in group 2 using a dual-cure composite resin. In group 3, intracanal anchorage was solely performed with a dual-cure composite. All teeth were restored with standardised direct composite crowns without a ferrule. After thermo-mechanical loading, static load was applied until failure. Fracture patterns were assessed, and a microscopic analysis was performed to analyse the occurrence of additional cracks.Results
Group 2 revealed a significantly higher median fracture value (408 N) than groups 1 and 3, while no difference was detected between group 1 (290 N) and group 3 (234 N) (p?=?.1417). In group 3, the more favourable fracture patterns were observed. However, the majority of teeth within this fracture category revealed additional minor cracks of the root.Conclusions
Within the limitations of this study, adhesive intracanal anchorage to a depth of 3 mm with resin composite only has the same fracture resistance as titanium posts conventionally cemented to a depth of 6 mm. Even teeth with repairable main fractures exhibited additional dentinal cracks on the root.Clinical relevance
Additional dentinal root cracks in the teeth with repairable main fractures may considerably impair their longevity. 相似文献6.

Background and objectives
Aortic stenosis is the most common type of heart valve disease. Percutaneous aortic valve replacement has become the alternative for patients considered at high risk for surgery. Controlled mechanical ventilation with tracheal intubation has been the choice for this type of procedure, however the use of noninvasive ventilation in cardiac patients has shown to be beneficial. Janus is a novel full‐face mask that allows application of noninvasive ventilation support during anesthesia. Our main objective was to evaluate the feasibility of transcatheter aortic valve replacement with prolonged transesophageal echocardiographic monitoring under deep inhalational sedation delivered through a new mask for noninvasive ventilation.Methods
A case series observational study that included five patients with critical aortic stenosis that underwent inhalational anesthesia with sevoflurane for transcatheter aortic valve replacement in a hybrid room of a teaching hospital. Standard monitors and bispectral index were used, followed by inhalational induction and placement of the Janus mask. Anesthesia was maintained with sevoflurane. Patients were transferred to intensive care unit after the procedure. Complications related to the mask use, transesofageal echocardiography accessibility and respiratory implications to the patients were recorded.Results
All procedures were uneventful and no major complications were observed intraoperatively. One patient presented CO2 retention (50 mmHg) and sevoflurane leak around the central opening of the mask, both without clinical significance.Conclusions
The use of inhalational anesthesia with the facial mask Janus is a safe and efficient alternative to general anesthesia with tracheal intubation for transcatheter aortic valve replacement and can easily accommodate the use of transesophageal echocardiography intraoperatively. 相似文献7.

Objectives
To analyse the safety, efficacy and quality of life of patients with male stress urinary incontinence after radical prostatectomy treated with the AdVance® and AdvanceXP® slings.Patients and method
The study included 92 patients with stress urinary incontinence after radical prostatectomy treated with the AdVance® and AdVanceXP® sling between May 2008 and December 2015. A perineal repositioning test was performed in all cases with sphincter coaptation of ≥ 1.5 cm. Mild stress urinary incontinence was defined as the use of 1-2 absorbers/24 h; moderate was defined as 3-5 absorbers/24 h; and severe was defined as more than 5 absorbers/24 h. Healing was defined as the total absence of using pads; improvement was defined as a reduction > 50% in the number of pads; and failure was defined as a reduction < 50, no improvement or worsened incontinence. Check-ups were conducted at 3, 12 and 36 months after the surgery. We employed the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) for the quality of life index. The complications are listed according to the Clavien-Dindo classification.Results
The degree of preoperative incontinence was mild in 23.9%, moderate in 67.4% and severe in 8.7% of the patients. The mean use of preoperative pads was 3.1 (range 1-6, 95% CI). The mean preoperative ICIQ-SF score was 16.5 (15-20). Sphincter coaptation ≥ 1.5 cm using the perineal repositioning test was present in 87 patients (94.6%). The mean follow-up from insertion of the sling was 42.1 months. Some 89.1% of the patients were healed at 3 months, 70.7% were healed at 12 months, and 70.4% were healed at 36 months. The ICIQ-SF score at 3, 12 and 36 months showed significant improvement (P < .001) compared with the preoperative score.Conclusions
The Advance® and AdvanceXP® system are effective over time in terms of urinary continence and patient satisfaction. 相似文献8.

We describe the case of a 33-year-old pregnant woman, gravida 1 para 0, who was referred to us with a presumptive diagnosis of an interstitial pregnancy. The patient had had amenorrhea for 7 weeks and had previously undergone myomectomy. Two-dimensional sonographic examination revealed a gestational sac located outside the uterine cavity but could not define its exact anatomic position. Using transvaginal 3-dimensional sonography, we were able to correctly depict the sac, which was located where the fallopian tube crossed the uterine horn. We performed a cornual resection, during which the diagnosis of interstitial pregnancy was confirmed. The use of 3-dimensional sonography in this patient's case thus led to appropriate early treatment and avoidance of possible subsequent morbidity. 相似文献
