Background: Ectopic pregnancy (EP) and its treatment methods may affect subsequent fertility outcomes. Objective: To compare methotrexate (MTX), laparoscopic salpingostomy, and salpingectomy methods of EP treatment and their effects on fertility outcomes. Materials and Methods: This retrospective cohort study was performed on women receiving a definitive diagnosis of tubular EP from 2014 to 2017 at Arash Medical Center, Tehran, Iran. In total, 194 women were studied, of which 64 were treated with MTX, 52 underwent salpingostomy, and 78 underwent salpingectomy, depending on their clinical status. Basic information, obstetrics history, and major outcomes of the treatment after an 18-month follow-up, including recurrence of EP, miscarriage, and successful intrauterine pregnancy (IUP), were recorded and variables were compared among the three groups. Results: There was no significant difference in fertility outcomes among the three groups. Among the studied variables, predictors of successful IUP after EP treatment were multiparity (Hazard Ratio (HR): 1.37; 95%CI: 1.06-1.77), no history of miscarriage (HR: 2.37; 95%CI: 1.01-5.56), and a higher number of live births (HR: 1.54; 95%CI: 1.01- 2.37). On the other hand, predictors of EP recurrence included nulliparity (HR: 1.61; 95%CI: 1.02-2.53) and a lower number of live births (HR: 3.84; 95%CI: 1.43-10.98). The effect of other factors, including the utilized therapeutic modalities, was not statistically significant. Conclusion: The current study results demonstrated that after an 18-month follow-up, fertility outcomes, including recurrence of EP and successful IUP, were not significantly different among the subjects with EP treated with MTX, salpingostomy, or salpingectomy. Further studies with long-term follow-ups are recommended. Key words: Ectopic pregnancy, Fertility, Methotrexate, Salpingostomy, Salpingectomy.

Abstract Background/aim The development of bronchopleural fistula (BPF) remains the most severe complication of lung resection, especially after pneumonectomy. Studies provide controversial reports regarding the benefits of flap reinforcement of the bronchial stump (FRBS) in preventing BPF’s occurrence. Methods This is a retrospective cohort study of 558 patients that underwent lung resection in a 12-year period (from 2007 to 2018). Ninety patients (16.1%) underwent pneumonectomy. Patient follow-up period varied from 1 to 12 years. Results Out of 558 patients in this study, 468 (83.9%) underwent lobectomy, and the remnant underwent pneumonectomy. In 114 cases with lobectomy, only 24.4% had FRBS, meanwhile in 56 cases with pneumonectomy only 62.2% had FRBS. BPF occurred in 8 patients with lobectomy (1.7%) and in 10 patients with pneumonectomy (11.1%). Among cases with post-pneumonectomy BPF, 6 (10.7%) had FRBS performed, while no FRBS was performed among patients with post-lobectomy BPF, although these data weren’t statistically (p > 0.05). In 24 patients (20 lobectomies and 4 pneumonectomies) with lung cancer (10.4%) neoadjuvant treatment was performed, in which 20 patients underwent chemotherapy and 4 underwent radiotherapy. FRBS was applied in each of the above 24 operative cases, but only in 4 of them the BPF was verified. Conclusion The idea of enhancing the blood supply through the FRBS for BPF prevention has gain traction. Although FRBS has been identified as valuable and effective method in BPF prevention following lung resection, our study results did not support this evidence.

Abstract Background Lateral tibial plateau fractures (TPFs) are often treated with conventional open reduction and internal fixation (ORIF) through standard anterolateral sub-meniscal arthrotomy. There has been increasing support for “bidirectional rapid redactor” device-assisted closed reduction and internal fixation (CRIF) for treating TPFs. The aim of the present study is to compare the clinical and radiological outcomes between CRIF and ORIF procedures. Methods We performed a retrospective cohort study of 55 lateral TPF patients (Schatzker types I–III) who accepted surgical treatment at our trauma level 1 center between January 2016 and January 2018. They were divided into the CRIF group (32 patients) and the ORIF group (23 patients) based upon the different surgical protocols. The patients’ clinical outcome analysis was evaluated by using the Knee Society Score (KSS) and Rasmussen’s clinical score. For radiological assessment, changes in tibial plateau width (TPW), articular depression depth (ADD), medial proximal tibial angle (MPTA), and posterior tibial slope angle (PTSA) were evaluated using radiographs and computed tomography (CT) scan. Results The CRIF group had a mean follow-up of 28.9 months, and the ORIF group had a mean follow-up of 30.7 months (p>0.05). Furthermore, there was no statistically significant difference in terms of age, gender, injury mechanism, follow-up time, time interval from injury to surgery, and Schatzker classification in the two groups. With respect to the clinical outcomes including the KSS score and Rasmussen’s clinical score, there was also no significant difference (p>0.05). Nevertheless, the CRIF group had lower intra-operative blood loss, shorter hospitalization days, and better range of movement of the knee joint than the ORIF group (p<0.05). Furthermore, CRIF had better radiological results when compared to the ORIF group using Rasmussen’s radiological score (p<0.05), although no significant difference was observed in TPW, ADD, MPTA, and PTSA between the two groups (p>0.05). Conclusion The present study showed that CRIF could achieve comparable clinical outcomes and better radiological results for treating lateral TPFs as compared with conventional ORIF.

Abstract Introduction Transcatheter left atrial appendage (LAA) occlusion is an alternative treatment in patients with atrial fibrillation (AF), high CHADSVASC Score and a contra-indication to anticoagulants. This retrospective cohort study aims to evaluate the impact of LLA morphology on procedure outcomes. Methods Patients from eight French centers who underwent left atrial appendage occlusion from February 2012 to January 2017 were included in this retrospective cohort study. LLA morphology was described by preoperative cardiac computed tomography (CT). Clinical data and Transoesophageal echocardiography (TEE) or CT results were collected during follow-up. Results Among 469 included patients, LAA morphologies were described in 215 cases 45.8%), 150 patients (70%) were implanted with Watchman devices, 57 (26%) with Amplatzer devices and 8 procedures (4%) failed. LAA Morphology was Chicken Wing (34%), Windsock (45%), cauliflower (18%) and 3% had another morphology including Cactus. There was no difference in patient characteristics between the different morphology groups. Mean follow-up was 9.6±11 months, during which 190 patients underwent LAA imaging (TEE in 171 and CT in 19 patients). There was no significant difference in the failure rate (p=0.72), duration of the procedure (p=0.065), peri-device leak (p=0.83) device-related thrombus (p=0.96) and the occurrence of stroke (p=1) during follow-up. Conclusion LLA morphology did not influence complication occurrence after occlusion in this cohort. Funding Acknowledgement Type of funding source: None

Aims To investigate the benefits of denosumab in combination with nerve-sparing surgery for treatment of sacral giant cell tumours (GCTs). Methods This is a retrospective cohort study of patients with GCT who presented between January 2011 and July 2017. Intralesional curettage was performed and patients treated from 2015 to 2017 also received denosumab therapy. The patients were divided into three groups: Cohort 1: control group (n = 36); cohort 2: adjuvant denosumab group (n = 9); and cohort 3: neo- and adjuvant-denosumab group (n = 17). Results There were 68 patients within the study period. Six patients were lost to follow-up. The mean follow-up was 47.7 months (SD 23.2). Preoperative denosumab was found to reduce intraoperative haemorrhage and was associated with shorter operating time for tumour volume > 200 cm3. A total of 17 patients (27.4%) developed local recurrence. The locoregional control rate was 77.8% (7/9) and 87.5% (14/16) respectively for cohorts 2 and 3, in comparison to 66.7% (24/36) of the control group. The recurrence-free survival (RFS) rate was significantly higher for adjuvant denosumab group versus those without adjuvant denosumab during the first two years: 100% vs 83.8% at one year and 95.0% vs 70.3% at two years. No significant difference was found for the three-year RFS rate. Conclusion Preoperative denosumab therapy was found to reduce intraoperative haemorrhage and was associated with shorter operating times. Adjuvant denosumab was useful to prevent early recurrence during the first two years after surgery. Cite this article: Bone Joint J 2020;102-B(2):177–185.

ABSTRACT Objective: To determine the incidence of post-operative bleeding among patients who underwent tonsillectomy alone versus tonsillectomy with fossa closure at the Victoriano Luna Medical Center from January 2015 to December 2017. Methods: Design: Retrospective Cohort Study Setting: Tertiary Military Hospital Patients: Medical records of 83 patients that underwent tonsillectomy under the Department of Otorhinolaryngology – Head and Neck Surgery between January 2015 to December 2017 were retrospectively reviewed for data regarding sex, age, tonsillectomy with or without fossa closure and post-operative bleeding. Cases of tonsillectomy alone versus tonsillectomy with fossa closure were compared (particularly with respect to post-operative bleeding), tabulated and statistically analyzed using risk ratio and t-test. Results: There were 57 cases of tonsillectomy alone versus 26 cases of tonsillectomy with fossa closure. The incidence of bleeding in all cases of tonsillectomy whether tonsillectomy alone or with fossa closure was 4.8%. The incidence of bleeding was higher in cases of tonsillectomy with fossa closure at 11.5% (versus 1.8% in tonsillectomy alone). Post-operative bleeding was 0.1 times more likely to occur in patients who underwent tonsillectomy alone than those who underwent tonsillectomy with fossa closure but there was no statistically significant difference in the risk of post-operative bleeding between the two. Conclusion: Although the incidence of bleeding was higher in cases of tonsillectomy with fossa closure, our results suggest that there is no statistically significant difference in risk for postoperative bleeding between tonsillectomy alone or tonsillectomy with fossa closure.

Abstract Background/Introduction Since patients with coronary ectasia have an increased risk of developing myocardial infarction and cardiovascular death, these patients could benefit from a more intensive treatment. Unfortunately, the evidence regarding outcomes with different management strategies is limited, especially with direct oral anticoagulants (DOAC). Purpose To compare clinical outcomes in patients with coronary ectasia based on the selected/chosen treatment strategy. Methods We conducted a retrospective cohort study in patients diagnosed with coronary artery ectasia. They were divided into 3 different groups based on the treatment they received at discharge and we evaluated the main cardiovascular outcomes at one-year follow-up. Results Between 2016 and 2019, 7,579 angiographies were performed, in which 510 patients with coronary ectasia were found (prevalence of 6.72%). Of these patients, 43.9% (n=224) had the diagnosis of STEMI, 21% NSTEMI (n=107), 5.1% unstable angina (n=26), 18.6% chronic stable angina (n=95) and other 11.4% (n=58). The angiographic distribution of the lesions was as follows: left main coronary artery 25.1%, Left descending coronary artery 62.7%, circumflex artery 52.1%, right coronary artery 79.2%. It was possible to obtain the follow-up of 363 patients (71.2%) because 25 died during their hospitalization and data of 122 were not available at the time of analysis. Three groups were formed based on the treatment: (1) Dual Antiplatelet Therapy (DAPT) in 47% (n=174); (2) DAPT + Vitamin K Antagonist (VKA) in 8.5% (n=31); (3) DAPT + DOAC in 6.6% (n=24). The overall MACE rate at 1-year of follow-up was 6.6% (n=15): 11 patients in the DAPT group (6.3%), 1 patient in the DAPT + VKA group (3.2%), and 3 patients in the DAPT + DOAC group (12.5%). During this period, 3 patients died from cardiovascular causes, all of them in the DAPT group. Myocardial infarction occurred in 12 patients, 8 in the DAPT group (4.2%), 1 in the DAPT + VKA group (3.2%) and 3 in the DAPT + DOAC group (12.5%). Stroke occurred in 2 patients: 1 patient in the DAPT group (0.5%) and 1 patient in the DAPT + DOAC group, 4.1% None of these findings were statistically significant. One-year occurrence of bleeding events was also evaluated: 23 patients presented a bleeding event, 14 in the DAPT group (8%), 7 in the DAPT + VKA group (22.5%) and 2 in the DAPT + DOAC group (8.3%); p=0.010. Conclusion(s) Our findings suggest that there is no statistically significant difference in the incidence of thrombotic complications, when comparing the treatment options. Patients using the combination of DAPT+VKA have a higher incidence of bleeding. FUNDunding Acknowledgement Type of funding sources: None.

BackgroundIntravitreal injections of topotecan are used in the management of retinoblastoma with vitreous seeds. This study evaluated whether intravitreal topotecan was associated with retinal toxicity.MethodsRetrospective cohort study of patients with retinoblastoma who were treated with intravitreal topotecan at Memorial Sloan Kettering Cancer Center between December 2014 and May 2019. Electroretinogram (ERG) responses under anaesthesia were measured immediately before treatment with intravitreal topotecan and at the next visitor approximately one-month. Ocular toxicity was defined by a decrease in the ERG response at 30 Hz at follow-up.ResultsOcular toxicity was evaluated by ERG on 50 evaluable injections administered to 28 eyes. 22 (44.0%) injections were performed with concurrent intravitreal melphalan. The median time to ERG measurement following an injection was 27 days. By using a paired t-test, intravitreal topotecan combined with melphalan (n=22) at a dose of 25 μg or 30 μg was associated with a significant decrease in ERG amplitude at follow-up (p=0.046, 95% CI −20.4 μV to −0.2 μV). Among eyes that only received topotecan (n=28) at doses of 20 μg or 30 μg, there was not a significant difference in ERG amplitude measured (p=0.85, 95% CI −7.0 μV to 5.8 μV).ConclusionIntravitreal topotecan combined with intravitreal melphalan was associated with a decrease in ERG amplitude; there was not a significant decrease in ERG amplitude observed in patients who received topotecan alone. These findings suggest that intravitreal topotecan injections at doses of 20 μg or 30 μg are not associated with retinal toxicity in patients with retinoblastoma.

Background: The direct-acting antiviral (DAA) agents are widely used to treat hepatitis C virus (HCV) genotype (GT) 1 infection, while it may cause severe liver damage. The objectives of the study were to evaluate the incidence of drug-induced liver injury (DILI), sustained virologic response at post-treatment week 12 (SVR12), and recurrence rates in HCV GT 1 infection.Methods: This was a retrospective cohort study that included patients diagnosed with HCV GT 1 infection, who had received intervention and treatment with elbasvir/grazoprevir (EBR/GZR) ± ribavirin (RBV) versus ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) + dasabuvir ± RBV (as control group) for 12 or 24 weeks at a regional hospital in southern Taiwan between April 2016 and August 2018. The primary outcome of the study was to compare the incidence rate ratio (IRR) of DILI via Poisson regression, and the secondary outcome was to evaluate the effectiveness of two treatment regimens expressed as a percentage.Results: The study included 149 patients in the control group and 105 patients in the intervention group of which 99.33 and 98.1% patients, respectively, achieved SVR12. In the control group, one patient experienced relapse, whereas in the intervention group, two patients relapsed. Furthermore, in the control group, a total of nine patients developed DILI as determined during follow-up care. Of these patients, three were 55–84 years old. In the intervention group, six patients developed DILI. The IRR of DILI caused by EBR/GZR treatment was 2.84 times higher than that caused by the OBV/PTV/r treatment regimen.Conclusion: There was no significant difference between the studied DAA regimens regarding the incidence of DILI and effectiveness during the treatment. DILI occurrence during therapy did not affect the cure rate of medication. The present study results can provide reference data for drug selection among patients with HCV.Trial registration: The study was approved by DMF-CYCH (CYCH IRB No: 2018067).

Background: Nonunion rates in hind or midfoot arthrodesis have been reported as high as 41%. The most notable and readily modifiable risk factor that has been identified is smoking. In 2018, 14.4% of the UK population were active smokers. We examined the effect of smoking status on union rates for a large cohort of patients undergoing hind- or midfoot arthrodesis. Methods: In total, 381 consecutive primary joint arthrodeses were identified from a single surgeon’s logbook (analysis performed on a per joint basis, with a triple fusion reported as 3 separate joints). Patients were divided based on self-reported smoking status. Primary outcome was clinical union. Delayed union, infection, and the need for ultrasound bone stimulation were secondary outcomes. Results: Smoking prevalence was 14.0%, and 32.2% were ex-smokers. Groups were comparable for sex, diabetes, and body mass index. Smokers were younger and had fewer comorbidities. Nonunion rates were higher in smokers (relative risk, 5.81; 95% CI, 2.54-13.29; P < .001) with no statistically significant difference between ex-smokers and nonsmokers. Smokers had higher rates of infection ( P = .05) and bone stimulator use ( P < .001). Among smokers, there was a trend toward slower union with heavier smoking ( P = .004). Conclusion: This large retrospective cohort study confirmed previous evidence that smoking has a considerable negative effect on union in arthrodesis. The 5.81 relative risk in a modifiable risk factor is extremely high. Arthrodesis surgery should be undertaken with extreme caution in smokers. Our study shows that after cessation of smoking, the risk returns to normal, but we were unable to quantify the time frame. Level of Evidence: Level III, retrospective cohort study.
