Validation of the Modena bleeding score in endoscopic sinus surgery

IntroductionThe Modena bleeding score is a categorical rating scale that allows the assessment of the surgical field in relation to bleeding during endoscopic surgery. It has recently been presented and validated in the field of endoscopic ear surgery by the present authors. The Modena bleeding score provides five grades for rating the surgical field during endoscopic procedures (from grade 1 ? no bleeding to grade 5 ? bleeding that prevents every surgical procedure except those dedicated to bleeding control).ObjectiveThe aim of this study was to validate the Modena bleeding score in the setting of endoscopic sinus surgery.MethodsFifteen three-minute videos of endoscopic sinus surgery procedures (each containing three bleeding situations) were evaluated by 15 specialists, using the Modena bleeding score. Intra and inter-rater reliability were assessed, and the clinical validity of the Modena bleeding score was calculated using a referent standard.ResultsThe data analysis showed an intra-rater reliability ranging from 0.6336 to 0.861. The inter-rater reliability ranged from 0.676 to 0.844. The clinical validity was α = 0.70; confidence limits: 0.64 ? 0.75, corresponding to substantial agreement.ConclusionThe Modena bleeding score is an effective method to score bleeding during endoscopic sinus surgery. Its application in future research could facilitate the performance and efficacy assessment of surgical techniques, materials or devices aimed to bleeding control during endoscopic sinus surgery.     

Survival in node-positive early oral squamous cell carcinoma: sentinel node biopsy versus elective neck dissection

Patients undergoing sentinel node biopsy (SLNB) for early oral squamous cell carcinoma (OSCC) who harbour occult metastases (pN+ve) may be at greater risk of mortality due to prolonged overall treatment times than those identified as pN+ve on elective neck dissection (ELND). A retrospective comparative survival analysis was therefore undertaken to test this hypothesis. Patients were identified from the South Glasgow multidisciplinary team (MDT) database. Group 1 comprised 38 patients identified as pN+ve, or who were false negative, on sentinel lymph node biopsy (SLNB). Group 2 comprised 146 patients staged pN+ve on ELND. The groups were compared with the Kaplan Meier method and Cox proportional hazards model. In addition, a matched-pair analysis was performed. A unique and specifically designed algorithm was deployed to optimise the pairings. No difference in disease-specific or overall survival was found between the groups. Patients undergoing SLNB as the initial neck staging modality in early OSCC and are identified as pN+ve do not appear to be at a survival disadvantage compared with those staged with ELND.     

Colonoscopy Versus Catheter Angiography for Lower Gastrointestinal Bleeding After Localization on CT Angiography

PurposeThe aim of this study was to compare catheter angiography (CA) and colonoscopy outcomes after successful CT angiographic (CTA) localization for patients with overt lower gastrointestinal bleeding (LGIB).MethodsSeventy-one consecutive patients from two institutions between 2010 and 2020 had both contrast extravasation on CTA imaging in the lower gastrointestinal tract and subsequent CA or colonoscopy. The primary outcome was confirmation of active bleeding during CA or colonoscopy (defined as confirmation yield). The secondary outcomes were to determine therapeutic yield (hemostatic therapy), time to procedure, rebleeding rate, and adverse outcome rates (defined as surgery, acute kidney injury, initiation of dialysis, and overall mortality). Univariate analyses and multivariable analyses with P < .05 were used to determine statistical significance.ResultsForty-four patients underwent CA and 27 underwent colonoscopy. CA had higher overall confirmation yield (55% vs 26%, P = .026), whereas therapeutic yields were similar (70% vs 56%, P = .214). Time to procedure was 5.1 ± 3.4 hours for CA and 15.5 ± 13.6 hours for colonoscopy (P < .001). On multivariable analysis, shorter time to procedure was the only statistically significant predictor of confirmation yield (P = .037) and therapeutic yield (P = .013), whereas procedure, hemoglobin, transfusions, and hemodynamic instability were not. Adverse events and rebleeding were not statistically different between patients who underwent CA and colonoscopy (P > .05).ConclusionsShorter time to procedure was the only statistically significant predictor of confirmation and therapeutic yield after CTA localization of LGIB. Because CA can be performed sooner than colonoscopy without increased rates of adverse outcomes or rebleeding, CA may be a reasonable first-line treatment option in patients with CTA localization of LGIB.     

Cáncer sincrónico de carcinosarcoma uterino y carcinoma seroso tubárico. A propósito de un caso y revisión de la bibliografía

We report a rare case of uterine carcinosarcoma involving a 74-year-old woman. The patient complained of posmenopausal bleeding. The disease was eventually diagnosed as simultaneous uterine carcinosarcoma and high-grade serous tubal carcinoma.Clinical examination found a cervical tumour and transvaginal ultrasound showed a heterogeneous intrauterine image. The histological result of both findings was carcinosarcoma.The computed tomography scan and magnetic resonance imaging reported similar findings for intrauterine and cervical tumour, with the same features as a possible myoma or mass with sarcomatous degeneration.Given the suspicion of a high-risk variant of endometrial adenocarcinoma, the primary management of carcinosarcoma is surgery. Complete surgical staging included total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic and para-aortic lymph node dissection.The pathological findings revealed a uterine carcinosarcoma tumour, invading less than half the myometrium and the stromal connective tissue of the cervix but not extending beyond the uterus. The histopathological studies of bilateral adnexectomy and the peritoneal biopsy demonstrated the presence of high-grade serous tubal carcinoma. The lymph study was negative for malignancy.We concluded a synchronous diagnosis of uterine carcinosarcoma stage II and high-grade serous tubal carcinoma stage IIIB.A detailed literature search and management of this entity are discussed.     

女性生育力评估

随着人口老龄化和生育力的下降,我国放开了三孩政策,对有生育要求的夫妇进行生育力评估显得非常必要。女性生育力与年龄关系密切,还依赖于卵巢、输卵管、子宫等生殖器官。本文就影响女性生育力的因素进行介绍。     

体位对超声评估前盆腔相关参数影响的病例交叉研究

摘 要 目的 探讨传统膀胱截石位与改良膀胱截石位对超声评估前盆腔相关参数的影响。方法 应用交叉设计二阶段法，将100例行盆底超声检查的患者随机分为两组（每组各50例），A组采用先传统体位后改良体位规范盆底超声，B组采用先改良体位后传统体位规范盆底超声检查，对比分析两种体位检查的成功率、静息状态、最大Valsalva动作时各盆腔参数的差异。结果 改良体位获得最大Valsalva动作的成功率大于传统体位（96% vs 90%），差异有统计学意义（χ2=4.348，P=0.037）。两种体位在静息状态时膀胱颈到参考线的距离、膀胱后角、尿道倾斜角比较差异均无统计学意义；改良体位在最大Valsalva动作时的膀胱后角、膀胱颈移动度、尿道旋转角均大于传统体位，差异均有统计学意义（P＜0.05），且上述参数受实验顺序影响不明显，改良体位下尿道漏斗形成率大于传统体位，差异有统计学意义（P＜0.05）。结论 体位因素对评估前盆腔相关参数具有影响，改良体位法获得的前盆腔相关参数与传统体位有一定差异，在临床应用中应注意合理解析。     

Articular degeneration after subchondral cementation for giant cell tumors at the knee

PurposeTo quantify joint degeneration and the clinical outcome after curettage and cementation in subchondral giant cell tumors of the bone (GCTB) at the knee.MethodsWe conducted a retrospective analysis of 14 consecutive patients (seven female, seven male) with a mean age of 34 years (range 19–51) who underwent curettage and subchondral cementation for a biopsy-confirmed GCTB at the distal femur or the proximal tibia between August 2001 and August 2017, with a mean follow-up period of 54.6 months (range 16.1–156 months). The Whole-Organ Magnetic Resonance Imaging Score (WORMS), Kellgren-Lawrence (KL) classification, and Musculo-Skeletal Tumor Society (MSTS) score were assessed.ResultsRadiological degeneration progressed from preoperative to the latest follow-up, with a median WORMS from 2.0 to 4.0 (p = 0.006); meanwhile, the median KL score remained at 0 (p = 0.102). Progressive degeneration (WORMS) tended to be associated with the proximity of the tumor to the articular cartilage (mean 1.57 mm; range 0–12 mm) (p = 0.085). The most common degenerative findings were cartilage lesions (n = 11), synovitis (n = 5), and osteophytes (n = 4). Mean MSTS score increased from 23.1 (preoperatively) to 28.3 at the latest follow-up (p < 0.01).Seven patients (50%) were treated for a local recurrence, with six revision surgeries performed. Removal of the cement spacer and filling of the cavity with a cancellous autograft was performed in seven patients. Conversion to a total knee arthroplasty was performed in one patient for local tumor control.ConclusionsCementation following the curettage of GCTB around the knee is associated with slight degeneration at medium-term follow-up and leads to a significant reduction in pain. Removal of the cement and reconstruction with an autograft may be beneficial in the long term.
