Significant Difference In Success Rate Research Articles

Efficacy and safety of CalliSpheres drug-eluting bead bronchial arterial infusion chemoembolization vs. bland embolization in advanced lung cancer with hemoptysis: A multicenter retrospective study.

Massive hemoptysis is a life-threatening complication in patients with advanced primary lung cancer, and effective, safe treatments are crucial. This study aimed to investigate the efficacy and safety of CalliSpheres drug-eluting bead bronchial arterial infusion chemoembolization (DEB-BACE) for managing this condition. A retrospective analysis included 144 patients with advanced primary lung cancer and massive hemoptysis treated at multiple hospitals from January 2019 to January 2023. Patients undergoing bronchial artery embolization were divided into two groups: the observation group (n=76) received CalliSpheres DEB-BACE with epirubicin, and the control group (n=68) received 8spheres blank embolization. Both groups achieved successful hemostasis, with no statistically significant difference in success rates (observation group: 88.16%, control group: 86.76%). However, the observation group had a significantly longer median duration without hemoptysis (96 days vs. 50 days). Two months post-therapy, the observation group showed higher objective response rates (82.89% vs. 38.24%) and disease control rates (92.11% vs. 66.18%) compared to the control group. Adverse reactions were manageable and similar between groups, with no serious complications observed. By January 31, 2024, the observation group had significantly longer median overall survival (11 months vs. 7 months). The DEB-BACE treatment demonstrates safety and efficacy in managing massive hemoptysis in patients with advanced lung cancer. However, the superiority of this approach over bland embolization remains to be established through well-designed prospective studies. Future research is anticipated to provide a definitive comparison and further validate the role of DEB-BACE in clinical practice.

Aintree Catheter Versus Gum Elastic Bougie for Airway Exchange Using the i-Gel Supraglottic Device: A Cadaver Study.

Airway compromise is the third leading cause of preventable death on the battlefield. Most combat medics carry supraglottic airway (SGA) devices for airway management. However, exchanging an SGA device for a definitive airway can be challenging, especially in austere environments. This study aims to compare the Aintree intubation catheter (AIC) to the gum elastic bougie (GEB) as adjuncts for performing airway device exchange with the i-gel SGA device in place. This randomized crossover cadaver study of 48 participants examined the success rate of two endotracheal introducers (AIC and GEB) when performing a blind airway exchange with an i-gel in place. Study participants were combat medics (MOS 68W), physician assistant students, physician assistant staff, emergency medicine (EM) physician residents, and emergency medicine attending physicians attending classes at the installation Medical Simulations Training Center. Each participant performed up to three attempts using both endotracheal tube introducers on the same cadaver. The primary outcome was successful airway exchange rate with each device, and the secondary outcome was time to successful airway exchange. Although the AIC had a slightly higher success rate of 33% compared to the GEB success rate of 30%, this result was not statistically significant, P = .56. Similarly, participants completed successful airway exchanges with the AIC faster, with a mean time of 86.5 seconds (95% CI: 71.2 to 101.9) versus 101.2 seconds (95% CI: 85.5 to 116.9) with the GEB. However, this result was also not statistically significant, P = 0.18. This study demonstrates no significant difference in success rate and time to completion of successful iterations of airway exchanges between the two devices. Although the AIC performed slightly better overall, these results are not statistically significant. Additionally, blind exchange intubations appear to be of high risk with minimal success, so we recommend against this technique in routine practice.

Effectiveness of pulpotomy in managing carious exposure in mature permanent teeth: A systematic review and meta-analysis

ObjectivesThis quantitative systematic review evaluated whether pulpotomy performed with hydraulic calcium silicate cements may be used as an alternative to root canal treatment (RCT) in mature permanent teeth with carious pulp exposure. Data sourcesA comprehensive search was conducted in PubMed, Web of Science, Scopus, and the Cochrane Library. No language restrictions were applied. The search included randomised controlled trials that compared pulpotomy to root canal treatment for managing carious exposure in mature permanent teeth. Study selectionStudies were selected based on predetermined inclusion criteria: randomised controlled trials involving mature permanent teeth with carious pulp exposure, using hydraulic calcium silicate cements for pulpotomy. Non-comparative studies, case reports, and trials involving primary or immature permanent teeth were excluded. DataData were extracted on success rates, clinical outcomes, follow-up periods, pain profiles, and potential complications. A meta-analysis was performed, revealing no statistically significant differences in success rates between pulpotomy and RCT. Both interventions demonstrated success rates exceeding 90 % at one-year and two-year follow-up periods. Pain profiles consistently showed lower post-operative pain intensity in the pulpotomy group compared to the RCT group during the first week. Potential complications, such as non-responsive pulp and difficulties in determining pulp vitality, were reported more frequently in the pulpotomy group. ConclusionsPulpotomy with bioactive hydraulic calcium silicate cements shows comparable success rates to RCT in managing carious pulp exposure in mature permanent teeth. The results suggest pulpotomy as a viable, less invasive alternative to RCT, particularly in cases where preservation of pulp vitality is paramount. Clinical significanceThis systematic review highlights pulpotomy as a less invasive and cost-effective alternative to root canal treatment in mature permanent teeth. With comparable success rates and lower post-operative pain, pulpotomy offers a promising approach to managing carious exposure and preserving tooth vitality.

Comparative efficacy of probing with or without intubation, and/or inferior turbinate fracture in simple congenital nasolacrimal duct obstruction: a randomized clinical trial

To compare the success rates of probing with or without monocanalicular intubation, and/or inferior turbinate fracture in resolving simple congenital nasolacrimal duct obstruction (CNLDO). A randomized, double-blind clinical trial was conducted on children aged 12–36 months exhibiting symptoms of epiphora and/or mucous discharge along with a positive fluorescein dye disappearance test (DDT). Patients were randomly assigned to one of the following interventions: (1) probing; (2) probing and monocanalicular intubation; (3) probing and inferior turbinate fracture; (4) probing, inferior turbinate fracture, and monocanalicular intubation. Participants were categorized into two age groups (12–24 months and 24–36 months) and assessed for resolution of CNLDO three months post-surgery. Success was defined as the absence of epiphora or mucopurulent discharge and a negative DDT. Among the 201 participants, 51 underwent probing alone, 53 underwent probing with intubation, 47 underwent probing with turbinate fracture, and 50 underwent probing with turbinate fracture and intubation. No significant differences were observed in age, gender, or laterality of the disease between the groups (Ps > 0.05). While there was no significant difference in success rates among interventions in both age groups (Ps > 0.05), patients aged 24–36 months who underwent interventions involving intubation exhibited a significantly higher success rate compared to those without intubation (93.0% vs. 76.2%; P = 0.018). However, this difference was not observed in patients aged 12–24 months (95.7% vs. 92.9%; P = 0.551). Incorporating interventions such as intubation and/or turbinate fracture alongside conventional probing does not significantly alter the success rate of simple CNLDO resolution in children aged 12–24 months. However, older patients (24–36 months) may derive greater benefits from interventions involving intubation.

355. LONG-TERM RESULTS OF LAPAROSCOPIC HELLER-DOR FOR ESOPHAGO-GASTRIC JUNCTION OUTFLOW OBSTRUCTION: A PROSPECTIVE CONTROLLED TRIAL

Abstract Background The gold-standard treatment for esophago-gastric junction outflow obstruction (EGJOO) is still debated. Currently, the management of this motility disorder reflects the experience gained with esophageal achalasia, for which Laparoscopic Heller-Dor (LHD) has been proven to be an effective long-term treatment. However, prospective data comparing long-term results of LHD for these two motility disorders are still lacking. The aim of this prospective, controlled study was to assess the 5-year follow-up of laparoscopic Heller-Dor (LHD) in patients with EGJOO, compared with radiological stage I achalasia patients (ACH). Methods Patients with diagnosis of idiopathic EGJOO, referred for dysphagia or food regurgitation, and radiological stage I achalasia (subgrouped by manometric pattern I, II & III), treated with LHD, were enrolled to the study and then followed prospectively for 5 years. During the follow-up patients were evaluated with Eckard score (ES), Barium-swallow X-ray, High Resolution Manometry (HRM), 24 hour pH-monitoring and Upper-Gastrointestinal endoscopy. The primary outcome was therapeutic success (presence of ES ≤3 or no additional treatment) at the 5-year follow-up assessment. The secondary outcomes included the postoperative IRP and the evidence of gastro-oesophageal reflux. Results The study involved 150 patients: 25 in the EGJOO group and 125 in the ACH group (25 pattern I, 74 pattern II, and 26 pattern III). The patients’ demographic and clinical parameters are summarized in Image. After 5 years, there was no significant difference in success rate: 92% in the EGJOO, 88% in achalasia pattern I, 91.9% in pattern II and 92.3% in pattern III (p=0.95). In the four groups, no differences were shown in the presence of postoperative esophagitis (p=0.08) and in the incidence of abnormal postoperative acid exposure (p=0.87) (Image). Conclusion This is the first long-term comparative study based on prospective data collection to assess the outcome of LHD in patients with EGJOO. After at least 5 years of follow-up, Laparoscopic Heller-Dor has a comparable success rate in both EGJOO and achalasia patients. Based on these data, we conclude that LHD can be proposed as a first-line treatment for symptomatic EGJOO, provided the diagnosis is accurate.

Novel Flowable Hemostatic Agent ActiClot: Efficacy and Safety Assessment in Rat and Porcine Models.

Background/Objectives: This study evaluated the hemostatic performance and safety of ActiClot (ATC), a new flowable hemostatic agent, through in vivo tests. Methods: ATC was compared with the commercially available FLOSEAL®. ATC consists of carboxymethyl starch, thrombin, and sorbitol powders in Syringe I, and a calcium chloride solution in Syringe II. In vivo evaluation used rat liver bleeding and porcine heart bleeding models. Safety was assessed using a rat subcutaneous implantation model. Results: ATC significantly reduced hemostasis time (70.00 ± 7.35 s) compared to gauze control (240.63 ± 32.31 s) in the rat liver model, showing a 70% reduction. There was no significant difference between ATC and FLOSEAL® (58.75 ± 13.42 s). In the porcine heart model, both agents achieved 100% hemostasis within 3 min, with no significant difference in success rates within 2 min (ATC 87.5%, FLOSEAL® 75%). The gauze control group failed in all tests. The rat subcutaneous implantation model showed no visual ATC observation after 48 h, indicating biocompatibility, with no inflammation observed. Conclusions: ATC demonstrated effective hemostatic performance similar to FLOSEAL® in two in vivo models, with faster hemostasis in the rat liver model. It also showed excellent safety and biocompatibility, indicating its potential for surgical and emergency bleeding control.

Male sling versus artificial urinary sphincter for the treatment of incontinence after prostate surgery: a systematic review with meta-analysis.

Urinary incontinence following prostate treatment (IPT) represents a significant complication that detrimentally impacts the quality of life for patients who have undergone prostate surgery. Presently, there is a scarcity of evidence regarding the preferred surgical techniques for IPT. We conducted a meta-analysis to compare the outcomes of the male sling and artificial urinary sphincter (AUS) in the treatment of IPT. Data were extracted through electronic literature searches on PubMed, Web of Science, and Embase databases until September 2023. Eligible studies included patients who underwent AUS or male sling procedures for IPT and had a follow-up duration exceeding 12 months. The primary end point was the success rate, with the secondary outcome focusing on complication rates. A fixed-effects or random-effects models were used to calculate the pooled estimate and its 95% confidence interval (CI). The publication bias was assessed using funnel plots and Egger's regression test. The meta-analysis included nine studies, involving a total of 1,350 participants. No statistically significant difference in success rates was found between AUS and male sling [odds ratio (OR): 0.96, 95% CI: 0.91-1.01]. In terms of the complication rate, there was no significant disparity between the two procedures (OR: 0.87, 95% CI: 0.86-1.12). The findings from this study indicated that male sling surgery yielded success and complication rates comparable to those of AUS. This suggests that male sling could serve as a viable alternative surgical option in the treatment of IPT.

The Prognostic Value of Active Otitis Media on Tympanoplasty Success Rate-A Systematic Review.

The aim is to investigate the influence of an active otitis media on the success rate of tympanoplasty in patients with a chronic otitis media (COM) and a tympanic membrane perforation. PubMed, Embase and the Cochrane Library. The inclusion criteria were studies on closure rates of tympanoplasty performed in COM patients of any age with a tympanic membrane perforation caused by COM. The exclusion criteria were studies on patients undergoing concomitant mastoidectomy, ossicular chain reconstruction, tuboplasty, adenoidectomy, revision tympanoplasty, patients with perforations due to other conditions than COM, and letters to editors, commentaries, conference abstracts and case reports. The included articles were critically appraised using the QUIPS tool. Data on tympanic membrane closure rate were extracted, odds ratio (OR) and 95% confidence intervals (CI) of the closure rate with a wet versus a dry ear were calculated. The search was performed on 1 February 2023. Of 4671 articles, 16 studies were included and critically appraised. Of these observational studies (nine prospective, seven retrospective), with a total of 1509 patients (dry ear group n = 1003; wet ear group n = 506), two studies stated a significant difference in success rate, one in favour of a dry ear and one in favour of a wet ear at time of surgery. All other studies did not show a statistically significant difference. Overall, the risk of bias was considered moderate to high. We found no significant prognostic value of having an active otitis media during tympanoplasty on tympanic membrane closure rates. Because the overall risk of bias was considered moderate to high, no strong conclusions can be made. To be able to answer this question with higher levels of evidence, high-quality prospective or randomized studies are needed.

Robot learning-enhanced tree-based algorithms for kinodynamic motion planning: A comparative analysis

Kinodynamic motion planning is pivotal in advancing robotics, en- abling autonomous systems to navigate dynamic environments effectively while adhering to both kinematic and dynamic constraints. This study delves into the efficacy of tree sampling-based planners, namely the Rapidly- exploring Random Tree (RRT), Rapidly-exploring Random Tree Star (RRT*), and Dominance Informed Region Trees (DIRT), in kinodynamic motion planning. Through a comparative analysis focusing on both fully informed and uninformed versions of these algorithms, I explore their performance in environments with dynamic constraints. Special emphasis is placed on the integration of learned controls, aiming to enhance maneuver planning. My research reveals significant differences in success rates, iterations, and path costs among the algorithms, underscoring DIRTs superiority under certain conditions and the beneficial impact of learned controls. These findings contribute valuable insights into the selection and optimization of motion planning algorithms, paving the way for more efficient and adapt- able autonomous systems.

Impact of a regional simulation-based training course in the implementation of external cephalic version: Intervention study.

The aims of this study were to assess whether a regional simulation-based training course in external cephalic version (ECV) would lead to the adoption of this technique in hospitals where it was not previously practiced, and to improve success rates in those already performing it. This was an intervention study where two specialists in obstetrics and gynecology from 10 Portuguese public maternity hospitals attended a structured simulation-based training in ECV. Hospitals were categorized based on whether ECV was conducted prior to the training program, and on their annual number of deliveries. Main outcomes were the number of ECVs performed in the 2 years before and after the course, and their success rates. Implementation of ECV was achieved in four additional hospitals during the 2 years following the course. Among the three hospitals already performing ECV and able to report their data, no significant differences in success rates were observed in the 2 years following the course (45.6% vs. 47.9%, P = 0.797). After a successful ECV, 77.7% of women had a vaginal delivery. A regional simulation-based training course in ECV led to an increase in the number of hospitals implementing the technique in the subsequent 2 years, but it did not impact the success rates in centers where it was already performed. This study highlights the potential of simulation-based courses in ECV, as well as the need to improve patients´ access to the technique and to centralize ECV services at a regional level.

The impact of disability on recruitment to higher surgical specialty training: A retrospective cohort study

BackgroundUK examining bodies are required to eliminate discrimination against people with protected characteristics. To achieve this in surgery, differential attainment (DA) in assessments used as gatekeepers to career progression must be ruled out. This study investigated the impact of disability status on the likelihood of success at national selection for Higher Surgical Training (HST). MethodsA retrospective cohort study of all UK graduates in the UKMED database (https://www.ukmed.ac.uk) who underwent selection for HST (ST3) from 2012 to 2019 (n = 2875). Univariate analysis identified differences in success rates at first-application. Logistic regression models identified whether disability was a predictor of success after adjusting for sociodemographic factors and prior MRCS performance. ResultsThere was no significant difference in success rates between candidates with and without disabilities (all p > 0.05) for any surgical specialty. Disability status was not a statistically significant predictor of success. Female candidates were 25 % more likely to be successful (OR 1.25 [95%CI 1.05 to 1.49]) and Non-White candidates were 20 % less likely to be successful (OR 0.80 [95%CI 0.68 to 0.96]). Candidates who passed MRCS Part A and Part B at the first attempt were 49 % (OR 1.49 [95%CI 1.25 to 1.77]) and 90 % (OR 1.90 [95%CI 1.58 to 2.28]) more likely to be successful. ConclusionNo significant difference was found in the likelihood of being successful at HST selection for any surgical specialty between applicants with and without disabilities, regardless of type of disability. DA was identified between other sociodemographic groups which requires further exploration.

Outcomes of Bladder Washout for the Treatment of Recurrent Urinary Tract Infections After Renal Transplantation.

Background Current literature suggests that anywhere from 2.9-27% of renal transplant recipients (RTR) will develop recurrent urinary tract infections (UTIs) (≥2 UTIs over six months or ≥3 UTIs over 12 months). Recurrent UTIs are of particular importance to RTR given its increased risk for allograft fibrosis and overall patient survival. Alternative solutions are needed for the management of recurrent UTIs, especially given the vulnerability of RTR to UTIs. We hypothesize that bladder washout (BW) reduces the incidence and recurrence of UTIs in RTR. Methods This is a retrospective study evaluating the utility of BW procedures on RTR diagnosed with recurrent UTIs between December 2013 and July 2021 at a single center. Results A total of 106 patients were included in the study with a total of 118 BW performed. 69% of patients were successfully treated with BW, meaning they no longer met the criteria for recurrent UTIs (<1 UTI) in the six-month post-BW period. The mean number of UTIs was 2.76 (range 2-7) before the BW and 1.16 (range 0-5) after the BW. On average, there were 1.60 fewer UTIs in the post-BW period compared to the pre-BW period (p<0.0001). There is no statistically significant difference in success rates stratified by bacterial class (p=1) or antimicrobial resistance class (p=0.6937). Conclusion BWdecreased the incidence of UTIs in the six-month post-operative period as nearly 70% of patients did not have UTI recurrence. This data provides evidence that BW may have utility in transplant recipients with recurrent UTIs. We hope this will stimulate further prospective randomized studies in this area.

Outcome of External Dacryocystorhinostomy Operation with and without Posterior Nasal Mucosal Flap Suturing Technique in Combined Military Hospitals of Bangladesh

Introduction: External Dacryocystorhinostomy is an anastomosing operation which creates a fistula between the medial wall of lacrimal sac and lateral wall of nasal cavity. Objectives: To compare the success rate by suturing both the anterior and posterior nasal mucosal flaps and without suturing the posterior nasal mucosal flap in External DCR surgery of 50 cases in different Combined Military Hospitals (CMH) of Bangladesh. Methods: The study included 50 cases of Chronic Dacryocystitis patients with symptoms of epiphora and blocked Sac Patency Test (SPT). External Dacryocysto- rhinostomy (DCR) surgery was done by same surgeon in different CMH over the period of 02 years extending from January 2016 to December 2017. Total 50 patients were divided into equal 02 groups. Group A underwent External DCR with silicone tube intubation and both anterior and posterior nasal mucosal flaps were sutured. Group B underwent similar DCR surgery where only anterior nasal mucosal flaps were sutured with lacrimal sac flap and posterior mucosal flap was excised completely. Results: External DCR surgery success rate was evaluated by a patent SPT at 03 months, 06 months and 12 months post operatively in both groups. SPT was successful in 92% cases in group A and 96% in group B at 3 months follow up after silicone tube removal. At 6 months reduction of epiphora occurred in 90% cases in Group A and 96% cases in Group B with unchanged SPT percentage. At 12 months follow up result remained unchanged as found at 6 months. There was significant difference in success rate of two different surgical technique. Quality of surgery improved with less intraoperative complications with shorter surgical time when only anterior nasal mucosal flap was sutured with excision of posterior nasal flap. Conclusion: This study suggested that comparing both the techniques of with and without suturing anterior and posterior nasal mucosal flaps in external DCR surgery, the later one makes considerable improvement in success rate of DCR. Excising the posterior nasal mucosal flaps can reduce operation time, improve operation technique and reduced epiphora post surgically. JAFMC Bangladesh. Vol 19, No 1 (June) 2023: 31-33

Comparing forceps and self-assembled intraocular rare earth magnet in removing metallic intraocular foreign bodies in 25-guage vitrectomy

PurposeTo compare the efficacy and efficiency of self-assembled intraocular rare earth magnet and forceps in removing intraocular foreign bodies(IOFBs) undergoing 25-gauge(G) pars plana vitrectomy.MethodsA total of 30 patients with metallic IOFB underwent 25-G PPV were enrolled into this study. Self-assembled intraocular rare earth magnet were used in 15 patients(bar group), and forceps were used in 15 patients(forceps group). Success rate of removing IOFB, time taken to remove IOFB, incidence of IOFB slippage and fall, iatrogenic retinal damages were compared between the two groups.ResultsThere was no significant difference in success rate of removing IOFBs between the groups(93.3% and 100%, P > 0.99). The median time taken of removing FB was significantly shorter in bar group than in forceps group(112 and 295 s, P = 0.001). None of the patients in bar group had IOFB slippage and fall, or related iatrogenic retinal damage in the process of removal. In forceps group, IOFB slippage and fall during removal were observed in 7 of 15(47.6%) patients, related iatrogenic retinal injuries were recorded in 6 of 15(40.0%) patients, both were significantly higher than bar group(P = 0.003 and P = 0.017, respectively).ConclusionsCompared with forceps, the assembled intraocular magnet can greatly reduce the possibility of IOFB slippage and fall, prevent related iatrogenic retinal damage, and shorten the time taken to remove IOFB. The assembled intraocular magnet can be an useful tool in removing metallic IOFBs in PPV.

Outcome of novel pulp capping modalities after full pulpotomy in teeth diagnosed with irreversible pulpitis: A prospective randomized clinical trial.

The study aimed to compare and evaluate the effect of biodentine (BD) alone, BD along with Lyophilised freeze dried platelet rich concentrate (LPC + BD), and BD along with low-level laser therapy (BD + LLLT) after pulpotomy in mature permanent molars with irreversible pulpitis. The study was designed as a randomized, pragmatic, parallel, double-blinded clinical trial registered under the Clinical Trial Registry-India (CTRI/2020/02/023245). 120 permanent molars fulfilling the inclusion and exclusion criteria with symptoms of irreversible pulpitis were randomized after performing pulpotomy into three pulp capping groups: Group 1, BD; Group 2, lyophilized freeze-dried platelet-rich concentrate + BD (LPC + BD); and Group 3, Low level laser therapy + BD Group 3, LLLT + BD. The intergroup comparison was done using one-way analysis of variance followed by the Bonferroni test. The level of significance and confidence interval were 5% and 95%, respectively. Interobserver reliability was measured using Cohen's kappa analysis. At 1 week, there was a significant difference (P < 0.005) observed in the mean postoperative pain levels between the three groups with Group 1 (BD) exhibiting the highest postoperative pain followed by Group 2 (LPC + BD) and least pain was exhibited by Group 3 (LLLT + BD). A similar pattern was observed regarding the analgesic intake with maximum frequency in Group 1 (BD) and least with Group 3 (LLLT + BD). No significant difference in success rates was reported among the groups. Pulpotomy as a treatment option for mandibular molars with irreversible pulpitis has an acceptable clinical success rate; however, long-term overall success rate remains questionable. The outcomes of incorporating adjunctive modalities with BD are remarkable and show tremendous potential for continued development and research.

Partial pulpotomy success in primary molars followed up for 24 months: A randomized controlled clinical trial using mineral trioxide aggregate, biodentine, and acemannan.

Finding the best treatment approach and suitable capping materials in primary molars with deep carious lesions remains unresolved. To compare the success rates of partial pulpotomy in deep caries lesions in primary molars treated with mineral trioxide aggregate (MTA), biodentine, or acemannan for 6-24 months. A parallel-design, non-inferiority randomized controlled clinical trial was performed. Ninety mandibular primary molars from 65 children meeting the criteria, aged 3-8 years, were included. After inflamed pulp tissue removal and hemostasis, each tooth was randomly allocated into the MTA control group, or the biodentine or acemannan experimental group (N = 30 per group). All teeth were restored with a stainless steel crown. The outcomes were evaluated for 6-24 months. A generalized estimating equation model was used to compare the overall success rate in each group. After 24 months, 58 children (83 teeth) were available for evaluation. The results indicated that the success rate in the MTA, biodentine, and acemannan groups was 83.3%, 76.9%, and 74.1%, respectively. No significant difference in success rates among groups, however, was observed at the 6- to 24-month follow-ups (at 24th month, p = .30). There was no statistically significant difference between MTA, biodentine, or acemannan in the partial pulpotomy success after 24 months.

Optimal dilation duration of 10 mm diameter balloons after limited endoscopic sphincterotomy for common bile duct stones: a randomized controlled trial

Limited endoscopic sphincterotomy (EST) combined with endoscopic papillary balloon dilation (EPBD) is widely used. However, the optimal duration of small balloon dilation in choledocholithiasis remains controversial. We aimed to determine the optimal duration for 10 mm diameter balloon dilation after limited EST in choledocholithiasis. In this randomized controlled clinical trial, 320 patients were randomly assigned to receive small balloon dilation (10 mm in diameter) for 1 min (n = 160) or 3 min (n = 160) after deep bile duct cannulation. No significant difference in success rate of stone extraction between the two groups was observed. The incidence of post-ERCP pancreatitis (PEP) was higher in the 1 min group (10.6%) than in the 3 min group (4.4%) (P = 0.034). The logistic regression analysis showed that guidewire into the pancreatic duct, cannulation time > 5 min and 1 min balloon dilation were independent risk factors for PEP. There were no significant differences in other post-ERCP adverse events such as acute cholangitis, bleeding, perforation, etc. between the two groups. In conclusion, 3 min in duration was determined to be the optimal dilation condition for the removal of common bile duct stones.

Treatment of Infantile Esotropia - Comparison Between Botulinum Toxin A and Bilateral Medial Rectus Recession.

The objective of the study is to evaluate the examination findings, treatment methods, and follow-up results of children diagnosed with infantile esotropia (IE) and to compare botulinum toxin A (BTA) and bilateral medial rectus (MR) recession surgery. We retrospectively reviewed the medical records of patients who were diagnosed with IE. The age of the patient and the angle of deviation were taken into account to determine the treatment. Patients who underwent bilateral MR recession surgery and BTA injection were analyzed and the BTA and surgical groups were compared. Successful correction was defined as orthotropia and a deviation of up to 10 prism diopters (PD) after one surgical procedure or 1-3 botulinum injections. Two hundred and forty-six patients with esotropia were included in the study. Twelve were followed up with refractive correction only. BTA injection was administered to 110 patients, while 124 patients underwent bilateral MR recession. The age of the patients ranged from three to 39 months. Patients were followed for at least 6 months, with a mean follow-up of 24.3 months in the BTA group and 21.7 months in the surgical group (p=0.23). The mean pre-treatment angle deviation was 38.9 PD in the BTA group and 40.1 PD in the surgical group (p=0.62). The success rate for patients with more than 30 PD of deviation was 72% in the surgical group compared to 36% in the BTA group (p<0.001). No statistically significant difference in success rate was observed in patients with deviations <30 PD (surgery 62%, BTA 55%, p=0.26). Surgical treatment of IE was more successful than BTA injection in patients with large angle deviations (>30 PD). BTA injection can be considered as an alternative to surgery in cases of small to moderate angle deviations (<30 PD).

Effect of previous administration of potassium iodine and different durations of low iodine diets for radioiodine therapy on the treatment of Graves' disease in iodine-rich areas.

To examine whether adherence to a low-iodine diet (LID) enhances the therapeutic efficacy of radioiodine therapy (RAI) in Graves' hyperthyroidism (GH) in iodine-rich areas. We retrospectively evaluated 185 patients with GH from Aichi (n = 114) and Hokkaido (n = 71) Prefectures. Patients aged ≥ 18years with GH who underwent RAI between December 2012 and March 2022 were divided into subgroups based on pretreatment with anti-thyroid drug (ATD) or potassium iodide (KI). Patients were followed up with LID from 18days (group A) or 7days (group H) before RAI to 3days after RAI. The dose of radioactive iodine 131 (131I) was adjusted to deliver > 100Gy to the thyroid. The associations between urinary iodine concentration on UIC2 vs. 24hRU and UIC2 vs. the 1-year RAI success rate (SR) were investigated. Compared with UIC1, UIC2 was significantly decreased in all subgroups (P < 0.01). An inverse correlation between UIC2 and 24hRU was observed in the four groups; however, the difference was insignificant. The SR in groups A and H was 85% and 89%, respectively. Univariate analysis revealed no association between UIC2 and SR in each group. Additionally, stratification of the 185 patients into quartiles using UIC2 yielded no significant differences in SR (p = 0.79). LID sufficiently reduced UIC in patients undergoing RAI. Although a lower UIC2 may increase 24hRU, it did not increase the success of RAI. The benefit of LID in enhancing the efficacy of RAI in GH treatment remains uncertain.

Comparison of perventricular and percutaneous ultrasound-guided device closure of perimembranous ventricular septal defects.

Ultrasound-guided percutaneous device closure of perimembranous ventricular septal defects (PmVSD) is a minimally invasive recent treatment approach. Perventricular PmVSD device closure is an emerging radiation-free intervention, yet it comes with certain limitations. No studies compared both of these treatment approaches. We performed a retrospective institutional data comparison of percutaneous (PCP Group, n = 138) and perventricular (PVP Group, n = 67) ultrasound-guided device closure procedures in 205 patients with PmVSD between March 2017 and December 2022. Patients of the PCP and PVP groups had a median age of 4.9 years (IQR, 3.1-14.0) and 5.3 years (IQR, 3.4-13.1) respectively. The median PmVSD diameter in the PCP Group was 4.0 mm (IQR, 3.3-5.3) and 5.2 mm (IQR, 4.0-7.0) in the PVP Group (p = 0.001). There was no significant difference in success rates between the PCP and PVP Groups (intention-to-treat population, 88.4% vs. 92.5%, p = 0.36; as-treated population, 88.4% vs. 89.3%, p = 0.84). 5/8 failed percutaneous cases that were shifted to the perventricular approach were successful. Compared to the PVP Group, patients of the PCP group experienced a significant decrease in ventilation time, drainage volume, and postoperative hospital stay (p < 0.001). The median follow-up period was 24 months (IQR, 6-42) for the PCP group and 61 months (IQR, 53-65) for the PVP group. The overall severe adverse event rate was 0% in the PCP group and 3.0% in the PVP group. Perventricular and percutaneous ultrasound-guided device closure of PmVSD are both effective and safe treatment options. The percutaneous approach offers less trauma and faster recovery and may be the preferred approach in selected patients.
