Background
The success of shoulder stabilization with the Latarjet procedure might depend on the size of the bone graft and the positioning of the coracoid at the glenoid. The aim of this study was to quantitatively assess the surface of the coracoid bone graft and to assess its positioning in the en-face view.Method
A series of 21 patients (17 men, 4 women, 26.1 ± 6.8 years—9 right, 12 left shoulders) were prospectively included and followed up with CT scans between December 2010 and April 2012 at an average of 2.4 ± 0.7 months postoperatively. The retrospective analysis of the CT scans was performed with Osirix? software. The coracoid surface was measured (cm2) in the sagittal plane. The positioning in relation to the center of the circumscribed circle of the glenoid was determined in the en-face clock face view of the glenoid.Results
The grafts had a mean surface of 1.61 ± 0.51 cm2 (mean ± standard deviation). The coracoid grafts were located between 01:05 hours (32.5°) and 05:33 hours (166.6°). Mean positioning was 02:00 hours (59.8° ± 16.1°) to 04:26 hours (133.0° ± 16.9°). The extent of the grafts was 73.2° ± 14.3°.Discussion
The positioning of the coracoid graft on the clock face of the glenoid is situated in the decisive zone of 02:30–04:20 hours. The mean surface of the graft is smaller than expected from anatomical studies, but restores in defect situations bone stock in the potential defect areas at the anterior glenoid rim.Level of evidence
Level IV, prospective case series, treatment study. 相似文献922.

Background
Blood flow in various organs is determined by an autoregulatory mechanism that guarantees constant organ perfusion over a wide range of arterial blood pressure changes. This physiological principle has been proven for the kidney, brain and intestinal tract, but so far not for bone. This study was carried out to determine whether there is an autoregulatory mechanism of bone or not.Methods
The fluorescent microsphere reference sample method was used to determine blood flow within the bone and kidneys. Eight anesthetized female New Zealand rabbits received left ventricular injections of fluorescent microspheres over a wide range of arterial pressure levels prior to removal of kidney, femur and tibia. Blood flow values were calculated by measurement of fluorescence intensity in kidney and bone and correlated to fluorescence intensity in the peripheral blood (reference sample).Results
Despite a reduction of mean arterial pressure from 100 to 80 mmHg bone blood flow remained constant. Further reduction of mean arterial pressure results in a linear decrease in bone blood flow.Conclusion
The correlation between arterial pressure and organ perfusion in the bone is similar to blood flow within the kidney, indicating the presence of an autoregulated blood flow mechanism within the bone tissue. 相似文献923.

Introduction and hypothesis
We describe differences in sexual activity and function in women with and without pelvic floor disorders (PFDs).Methods
Heterosexual women ≥40 years of age who presented to either urogynecology or general gynecology clinics at 11 clinical sites were recruited. Women were asked if they were sexually active with a male partner. Validated questionnaires and Pelvic Organ Prolapse Quantification (POP-Q) examinations assessed urinary incontinence (UI), fecal incontinence (FI), and/or pelvic organ prolapse (POP). Sexual activity and function was measured by the Female Sexual Function Index (FSFI). Student’s t test was used to assess continuous variables; categorical variables were assessed with Fisher’s exact test and logistic regression. Univariate and multivariate analyses were used to assess the impact of pelvic floor disorders (PFDs) on FSFI total and domain scores.Results
Five hundred and five women met eligibility requirements and gave consent for participation. Women with and without PFDs did not differ in race, body mass index (BMI), comorbid medical conditions, or hormone use. Women with PFDs were slightly older than women without PFDs (55.6?+?10.8 vs. 51.6?+?8.3 years, P <0.001); all analyses were controlled for age. Women with PFDs were as likely to be sexually active as women without PFDs (61.6 vs. 75.5 %, P?=?0.09). There was no difference in total FSFI scores between cohorts (23.2?+?8.5 vs. 24.4?+?9.2, P?=?0.23) or FSFI domain scores (all P?=?NS).Conclusion
Rates of sexual activity and function are not different between women with and without PFDs. 相似文献924.

Objectives:
The primary objective was to examine the safety and feasibility of robotic-assisted laparoscopy in a cohort of women treated surgically for stage III and IV endometriosis. The secondary objective was to explore whether the stage of endometriosis affected surgical outcome.Methods:
In this cohort study, 43 women with severe endometriosis were treated with robot-assisted laparoscopic hysterectomy with unilateral or bilateral salpingo-oophorectomy for stage III (n = 19) or stage IV (n = 24) disease.Results:
Histopathologic evaluation confirmed endometriosis in all patients, and fibroids were also shown in 12 patients. The median actual operative time was 145 min (range, 67–325 min), and the median blood loss was 100 mL (range, 20–400 mL). All but one of the procedures were completed successfully robotically. The length of hospital stay was 1 d for 95% of patients (41 of 43), and 2 patients had prolonged stays of 4 d and 5 d, respectively. One patient was readmitted for a vaginal cuff abscess; this represented the only complication identified in this series.Conclusions:
Robot-assisted laparoscopic surgery appears to be a reasonably safe and feasible method for the definitive surgical management of women with severe endometriosis. 相似文献927.

Background
Surgical treatment of acute complicated sigmoid diverticulitis is still under debate while elective treatment of recurrent diverticulitis has proven benefits. The aim of this study was to evaluate the clinical and histological outcome of acute and elective laparoscopic sigmoid colectomy in patients with diverticulitis.Methods
A retrospective review was conducted where 197 patients were analyzed undergoing laparoscopic sigmoid resection for acute complicated diverticulitis and recurrent diverticulitis. Single-stage laparoscopic resection and primary anastomosis were routinely performed using a 3-trocar technique. Recorded data included age, sex, American Society of Anesthesiologists (ASA)-score, operative time, duration of hospital stay, complications, and histological results.Results
Ninety-one patients received laparoscopy for acute diverticular disease (group I) and 93 patients underwent elective laparoscopic sigmoid resection for diverticulitis (group II). M/F ratio was 49:42 for group I and 37:56 for group II. Mean operative time and hospital stay was similar in both groups. Majority of patients were ASA II in both groups. Rate of minor complications was 14.3 % in group I and 7.5 % in group II. Major complications were 2.2 % for acute treatment and 4.3 % for elective resections. No anastomotic leakage and no mortality occurred. In 32.3 % of the patients of elective group II, destruction of the colonic wall with pericolic abscess, fistulization, or fibrinoid purulent peritonitis were identified.Conclusions
Laparoscopic surgery for acute diverticular disease is safe and effective. Continuing bowl inflammations in histological specimens justify sigmoid resection in elective patients, but more effective pre-operative parameters need to be found to identify patients that would benefit from surgery during the initial episode. 相似文献928.
