Comparative analyses of short- and long-term outcomes between endoscopic submucosal dissection and endoscopic laryngo-pharyngeal surgery for superficial pharyngeal carcinomas.

Objectives: Endoscopic treatment of superficial pharyngeal carcinomas includes endoscopic submucosal dissection (ESD; usually performed by endoscopists), and endoscopic laryngo-pharyngeal surgery (ELPS; primarily performed by otolaryngologists). Few studies have compared the efficacy of the two techniques in treating superficial pharyngeal carcinomas. In this study, we compared the outcomes of these two techniques to determine the advantages. Methods: We retrospectively examined the short- and long-term outcomes of 93 consecutive patients with superficial pharyngeal carcinoma who either underwent an ESD or ELPS between August 2008 and December 2021. Results: There were 35 lesions among 29 patients and 93 lesions among 71 patients in the ESD and ELPS groups, respectively. The ELPS group had a significantly shorter procedure time (121.2 ± 97.4 min vs. 54.7 ± 40.2 min, p<0.01), greater procedure speed (0.10 ± 0.06 min/min vs. 0.30 ± 0.23 min/min, p<0.01), and less laryngeal edema than that of the ESD group. There were no significant differences in the 3-year overall, relapse-free, or disease-specific survival rates between the two groups. Intervention with ESD during ELPS was most commonly required when it was difficult to secure the visual field. Conclusions: There were no differences in batch resection rates or long-term prognoses between the two groups; nevertheless, the ELPS group had a shorter treatment time and less laryngeal edema than the ESD group. However, the treatment of narrow areas, such as the esophageal inlet patch, is a technical limitation of ELPS; thus, ELPS should be combined with ESD techniques.

Sino-nasal outcome Test-22 and Lund-Mackay CT score to select endoscopic sinus surgery in chronic rhinosinusitis.

Objectives: Chronic rhinosinusitis is one of the common diseases that cause morbidity and affects a person's quality of life. We tried to provide a more appropriate and effective approach to selecting patients for endoscopic sinus surgery. Methods: The study population is chronic rhinosinusitis children referred to the ear, nose, and throat clinic of two general hospitals in Tehran, Iran, who have previously undergone sufficient drug treatment and have not recovered. The Lund-Mackay score is calculated by examining the computed tomography (CT) scan. The Sino-nasal Outcome Test-22 (SNOT-22) questionnaire was provided to the patients before the operation, after the operation, and 3 and 6 months later in the clinic. Results: Before the operation, the most SNOT-22 score people were in the range of 40-59 points. The SNOT-22 score before the operation is significantly different from 3 and 6 months after the operation. The highest frequency of Lund-Mackay CT (LMCT) scan score was in the range of 18-23 points. The LMCT scan score did not show any significant relationship with the SNOT-22 score before surgery, 3 months, and 6 months after surgery. Sensitivity to aspirin had a significant relationship with SNOT-22 scores and the history of asthma and nasal polyps had a significant relationship with the preoperative LMCT scan score. Conclusions: The LMCT scan scoring system cannot be a good measure of chronic rhinosinusitis severity or the prognosis of patients after surgery. The SNOT-22 questionnaire can be used as a predictive tool to help the doctor and the patient in deciding to operate and the possibility of obtaining a relative recovery.

Effects of Pre_Operation Desogestrel Estradiol in Endometrial Preparation at Hysteroscopic Polypectomy.

Background: Hysteroscopic surgery is a common gynecologic process in many conditions. Endometrial thinning is the main successful key for this process associated with many preoperative preparations. This study aimed to evaluate DE (Desogestrel-estradiol) to reduce endometrial thickness in comparison with the control group. Materials and Methods: This Randomized clinical trial was done on the patients candidate for polypectomy that were randomly divided into two groups of intervention and control; the first group received DE OCP (oral contraceptive pill with 30 microgram Ethinyl estradiol + 150 micro gram Desogestrel) once daily from the 1st to 5th day of the menstrual cycle for 21 days and then in the first day of next menstruation cycle, the drug was used up to one day before hysteroscopy done in the 5th to 8th day of the cycle. The second group received no drugs. Hysteroscopy was done in the early follicular phase in both groups and all the subjects received one dosage of Misoprostol a night before surgery. Results: There were no significant differences between the parity, polyp size, and BMI (Body Mass Index) in the two groups. The mean duration of surgery, mean endometrial thickness before hysteroscopy, the quality of endometrial tissue, and surgeon satisfaction were significantly difference between the two groups. However, the quality of the surgeon's vision in the intervention group was better than the control group but there was no significant difference between the two groups. Conclusion: Pre-operation endometrial thinning by oral contraceptives such as DE could be an effective method and reduce the duration of surgery.

Chinese expert consensus on standard technical specifications for a gut microecomics laboratory (Review).

The intestinal microbiota is a complex ecosystem that not only affects various physiological functions, such as metabolism, inflammation and the immune response, but also has an important effect on the development of tumors and response to treatment. The detection of intestinal flora enables the timely identification of disease-related flora abnormalities, which has significant implications for both disease prevention and treatment. In the field of basic and clinical research targeting gut microbiome, there is a need to recognize and understand the laboratory assays for gut microbiomics. Currently, there is no unified standard for the experimental procedure, quality management and report interpretation of intestinal microbiome assay technology. In order to clarify the process, the Tumor and Microecology Committee of China Anti-Cancer Association and the Tumor and Microecology Committee of Hubei Provincial Immunology Society organized relevant experts to discuss and put forward the standard technical specifications for gut microecomics laboratories, which provides a basis for further in-depth research in the field of intestinal microecomics.

Three-dimensional computer navigation in the reconstruction of complex unilateral orbital fractures: evaluation and review of applications.

BACKGROUND: The eyes are the central aesthetic unit of the face. Maxillofacial trauma can alter facial proportions and affect visual function with varying degrees of severity. Conventional approaches to reconstruction have numerous limitations, making the process challenging. The primary objective of this study was to evaluate the application of three-dimensional (3D) navigation in complex unilateral orbital reconstruction. METHODS: A prospective cohort study was conducted over 19 months (January 2020 to July 2021), with consecutive enrollment of 12 patients who met the inclusion criteria. Each patient was followed for a minimum period of 6 months. The principal investigator carried out a comparative analysis of several factors, including fracture morphology, orbital volume, globe projection, diplopia, facial morphic changes, lid retraction, and infraorbital nerve hypoesthesia. RESULTS: Nine patients had impure orbital fractures, while the remainder had pure fractures. The median orbital volume on the normal side (30.12 cm3; interquartile range [IQR], 28.45-30.64) was comparable to that of the reconstructed orbit (29.67 cm3; IQR, 27.92-31.52). Diplopia improved significantly (T(10) = 2.667, p = 0.02), although there was no statistically significant improvement in globe projection. Gross symmetry of facial landmarks was achieved, with comparable facial width-to-height ratio and palpebral fissure lengths. Two patients reported infraorbital hypoesthesia at presentation, which persisted at the 6-month follow-up. Additionally, five patients developed lower lid retraction (1-2 mm), and one experienced implant impingement at the infraorbital border. CONCLUSION: Our study provides level II evidence supporting the use of 3D navigation to improve surgical outcomes in complex orbital reconstruction.

Randomized study for a novel elbow joint fixation device on postoperative complications in patients undergoing percutaneous coronary diagnostic or therapeutic procedures through the brachial artery.

Brachial artery access for coronary diagnostic or therapeutic procedures is associated with a greater risk of vascular complications. To determine whether 3D printing of a novel elbow joint fixation device could reduce postoperative complications after percutaneous coronary diagnostic or therapeutic procedures through the brachial artery. Patients who underwent percutaneous coronary diagnostic or therapeutic procedures by brachial access were randomly assigned to receive either a 3D-printed elbow joint fixation device (brace group) or traditional compression (control group) from March 2023 to December 2023. The severity of puncture site-related discomfort at 24 h postsurgery was significantly lower in the brace group (P = 0.014). Similarly, the upper arm calibration rate at 24 h postsurgery was significantly lower in the brace group [0.024 (0.019-0.046) vs. 0.077 (0.038-0.103), P < 0.001], as was the forearm calibration rate [0.026 (0.024-0.049) vs. 0.050 (0.023-0.091), P = 0.007]. The brace group had a significantly lower area of subcutaneous hemorrhage at 24 h postsurgery [0.255 (0-1.00) vs. 1 (0.25-1.75) cm2]. In patients who underwent percutaneous coronary diagnostic or therapeutic procedures by brachial access after manual compression hemostasis, the novel elbow joint fixation device was effective at reducing puncture site-related discomfort, alleviating the degree of swelling, and minimizing the subcutaneous bleeding area. Additionally, no significant complications were observed.Trial registration: China Clinical Trial Registration on 01/03/2023 (ChiCTR2300068791).

A Prospective Study on Fixation of Syndesmotic Ankle Injury: Tight Rope Versus Screw Fixation.

Background Syndesmotic injury can result in significant instability and long-term complications if not treated correctly. Traditional management has involved transyndesmotic screw fixation, but a newer technique, the tight rope system, has been developed to mitigate some of the issues related to screw fixation, such as hardware discomfort and the necessity for hardware removal. Methods In this randomized, prospective study, 32 patients with ankle injuries requiring syndesmotic fixation were equally divided into two groups: one receiving the tight rope system (n=16) and the other undergoing screw fixation (n=16). The patients were monitored for six months following surgery. The study measured outcomes such as time to weight-bearing, range of motion, pain levels, functional outcomes using the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale, and complication rates. Results Both groups had comparable demographic and injury profiles. The tight rope group achieved weight-bearing significantly earlier (6.19 ± 0.9 weeks vs. 7.13 ± 0.95 weeks, p=0.008) and had better functional outcomes at six months (87.5% excellent AOFAS scores vs. 37.5%, p=0.003) compared to the screw fixation group. The range of motion and pain scores were similar between the groups. Different complications were observed: screw breakage was more common in the screw fixation group, while the tight rope group experienced more laxity. Overall complication rates were similar. Conclusion Both techniques were effective in reducing pain and maintaining range of motion. However, the tight rope system allowed for earlier weight-bearing and better functional outcomes at six months. These results indicate that the tight rope system may provide certain advantages in treating syndesmotic injuries, although the choice of technique should be tailored to the specific injury and patient factors.

An Unusual Presentation of an Amniotic Fluid Embolism: Fetal Bradycardia As the First Sign.

Amniotic fluid embolism (AFE) is a potentially fatal maternal condition demanding awareness from obstetricians and anesthesiologists regarding its different manifestations. The typical presentation involves maternal respiratory distress, cardiovascular collapse, neurological changes, and coagulopathy followed by fetal distress. This unusual case study emphasizes that fetal compromise may precede maternal decompensation as the initial sign of AFE. Fetal distress is a known symptom of AFE and is typically seen due to cardiorespiratory issues that lead to reduced uteroplacental perfusion, resulting in fetal hypoxia. In the case presented, fetal bradycardia occurred before any visible maternal symptoms, suggesting that fetal distress could be induced by factors independent of the mother's cardiopulmonary status. A 34-year-old healthy G4P2012 at 41 weeks and 2 days gestation who was initially laboring on the floor was emergently taken to the operating room for a cesarean delivery due to fetal bradycardia. Around the time the fetus was delivered, the patient displayed seizure activity, followed by a complete loss of consciousness and cardiac arrest. The patient was intubated and underwent cardiopulmonary resuscitation and defibrillation, subsequently converting to a wide complex tachycardia. In the operating room, there was evidence of heavy vaginal bleeding, uterine atony, and a fulminant form of disseminated intravascular coagulopathy (DIC), which required aggressive management over the next four hours. After achieving hemodynamic stability, the patient was transferred to the surgical intensive care unit (SICU), extubated on day 3, and discharged home on day 8.

Coding and coverage for cardiac CT in the era of algorithm-based healthcare procedures and services.

In order for patients to gain the benefit of innovation in cardiac CT, it is necessary for coding, coverage, and payment to adapt to the novelty of algorithm-based healthcare procedures and services (ABHS). Appendix S to the CPT Code Set, the "AI Taxonomy", enables creation of discrete and differentiable codes for reimbursement of ABHS which has been clinically validated and FDA-labeled. Payment policy in OPPS and PFS is evolving to take account of the unique opportunities and issues arising from the clinical adoption of ABHS.

Real-world effectiveness of eptacog beta in patients with haemophilia and inhibitors: A multi-institutional case series.

INTRODUCTION: The management of bleeding events (BEs) in haemophilia A (HA) and B (HB) patients with inhibitors necessitates the use of bypassing agents. The recombinant factor VIIa bypassing agent eptacog beta has demonstrated efficacy at treating BEs and managing perioperative bleeding in adults in phase three clinical studies. AIM: To provide real-world descriptions of eptacog beta use for BE treatment in patients on emicizumab or eptacog beta prophylaxis. METHODS: This is a retrospective case series of 14 patients who received eptacog beta at seven haemophilia treatment centres, with HA (n = 11) or HB (n = 3) and inhibitors or anaphylaxis to factor replacement. RESULTS: Twenty-four spontaneous and traumatic BEs are described (muscle hematomas, joint hemarthroses, port site, and epistaxis) involving 11 subjects. Eptacog beta was effective for acute bleed treatment as both first-line therapy and for treatment of BEs refractory to eptacog alfa in 23/24 events. When eptacog beta was used for prophylaxis, 2/3 patients reported a decreased frequency of breakthrough BEs compared with prophylactic eptacog alfa and one patient experienced a similar frequency of breakthrough BEs compared with prophylactic activated prothrombin complex concentrate. Eptacog beta provided effective bleed control for three subjects who underwent minor surgical procedures. Treatment with eptacog beta was estimated to be 46%-72% more cost-effective than eptacog alfa. No safety concerns or adverse events were reported. CONCLUSIONS: In this case series, eptacog beta was safe, effective, and economical as first-line therapy, treatment of refractory BEs, management of perioperative bleeding, or prophylaxis in haemophilia patients with inhibitors.

First impressions of Telesurgery robotic-assisted radical prostatectomy using the Edge medical robotic platform.

PURPOSE: We reported, as a referral center in prostate cancer, our perspectives and experience performing Telesurgery using robotic surgery and 5G network. MATERIAL AND METHODS: We described and illustrated the Telesurgery applications and outcomes to treat a patient with prostate cancer located 1300 kilometers away from the surgeon (Beijing-Harbin) in China. We used the Edge Medical Robot (MP1000) in November 2023 in a 71-year-old patient with Gleason 6 (ISUP 1) in 8 cores from 13, PSA of 14 ng/dL, and clinical stage cT2a. MRI described a PIRADS 5 nodule on the left peripheral zone at the base, and 20gr prostate. We described details about the connection between centers, perioperative outcomes, and our perspectives as a referral center in prostate cancer. RESULTS: We had no delays, or problems with network connection between the centers. The procedure was performed in 60 minutes, with no intra- or postoperative complications. Estimated blood loss was 100 mL. The patient was ambulating soon after anesthesia recovery. Final pathology described a Gleason 6 (ISUP 1) involving the left base and left seminal vesicle, negative surgical margins, and no lymph node involvement (pT3bN0). The patient was continent soon after catheter removal (7 days). CONCLUSION: As technological progress introduced novel robotic platforms and high-speed networks, the concept of Telesurgery became a tangible reality while 5G technology solved latency and transmission concerns. However, with these advancements, ethical considerations and regulatory frameworks should underline the importance of transparency and patient safety with responsible innovation in the field.

Evaluating Experts' Consensus on Behavioral Principles.

Over the history of our field, scholars have emphasized the critical importance that behavioral principles play in applied behavior analysis, underlining their central position as the foundation on which the field is built. Therefore, behavior analysts must have a robust comprehension of behavioral principles to be conceptually systematic, starting with understanding what constitutes a behavioral principle. Although one might assume that the behavior analytical literature clearly identifies a set of basic principles that define our field, there is no generally agreed-upon list. This study aimed to get consensus from doctoral-level behavior analysts on what they viewed as the basic principles of behavior analysis. To do so, we created a list of terms from behavior analysis texts and surveyed participants to identify whether each term constituted a basic principle or a behavioral procedure. The results suggest that there is not good consensus on what constitutes behavioral principles among doctoral-level behavior analysts who completed the survey and that there may be differences in the views of faculty and nonfaculty behavior analysts. Potential contributing factors to these results are discussed. This survey study constitutes a first step in focusing behavior analysts on this important topic and starting a discussion that could further clarify the principles that define our field.

Efficacy and Outcomes of Para-Annular Plication in Mitral Valve Repair via Right Mini-Thoracotomy.

PURPOSE: We aim to assess the efficacy and safety of left atrial plication (LAP), particularly para-annular plication, using a right mini-thoracotomy approach. METHODS: Among 90 mitral valve repair (MVr) procedures performed at our institution between 2016 and 2023, 16 left atrial plication cases for left atrial enlargement (diameter: >50 mm) were assessed; nine cases underwent median sternotomy (conventional) (Group C), and seven cases underwent minimally invasive cardiac surgery (MICS) (Group M). The surgical protocol involved mitral valve repair via a right-sided left atrial approach, incorporating para-annular plication to suture the posterior wall. The mean follow-up duration was 3.3±2.4 years. RESULTS: Mortality within 30 days of surgery or during hospitalization did not occur. Postoperative complications included one case in each group that required reoperation for hemorrhage originating extraneously in the left atrium. Postoperative echocardiographic assessments revealed a comparable reduction in left atrial diameter (C/M: 80.3±7.0/80.7±14.6%; p=0.94), left atrial volume index (55.6±19.3/68.3±34.1%; p=0.36), and aorto-mitral angle (AMA) enlargement (113.8±7.3/107.5±12.2%; p=0.22). The three-year survival rate (88.9%/75.0%; p=0.33) was comparable between groups. CONCLUSION: The synergistic utilization of left atrial plication with para-annular plication via right mini-thoracotomy can enhance the postoperative outcomes of mitral valve repair.

Perioperative outcomes of robot-assisted pancreatoduodenectomy (PD) and totally laparoscopic PD after overcoming learning curves with comparison of oncologic outcomes between open PD and minimally invasive PD.

Backgrounds/Aims: Minimally invasive pancreatoduodenectomy (MIPD), such as totally laparoscopic pancreatoduodenectomy (TLPD) or robot-assisted pancreatoduodenectomy (RAPD), is increasingly performed worldwide. This study aimed to compare the perioperative outcomes of TLPD and RAPD, and compare the oncologic outcomes between MIPD and open pancreatoduodenectomy (OPD) for malignant disease. Methods: This retrospective study was conducted at two hospitals that followed similar oncological surgical principles, including the extent of resection. RAPD was performed at Seoul National University Hospital, and TLPD at Seoul National University Bundang Hospital. Patient demographics, perioperative outcomes, and oncological outcomes were analyzed. Propensity score matching (PSM) analysis was performed to compare oncologic outcomes between MIPD and OPD. Results: Between 2015 and 2020, 332 RAPD and 178 TLPD were performed. The rates of Clavian-Dindo grade ≥ 3 complications (19.3% vs. 20.2%, p = 0.816), clinically relevant postoperative pancreatic fistula (9.9% vs. 11.8%, p = 0.647), and open conversions (6.6% vs. 10.5%, p = 0.163) were comparable between the two groups. The mean operation time (341 minutes vs. 414 minutes, p < 0.001) and postoperative hospital stay were shorter in the RAPD group (11 days vs. 14 days, p = 0.034). After PSM, the 5-year overall survival rate was comparable between MIPD and OPD for overall malignant disease (58.4% vs. 55.5%, p = 0.180). Conclusions: Both RAPD and TLPD are safe and feasible, and MIPD has clinical outcomes that are comparable to those of OPD. Although RAPD exhibits some advantages, its perioperative outcomes are similar to those associated with TLPD. A surgical method may be selected based on the convenience of surgical movements, medical costs, and operator experience.

ArtiSential® laparoscopic cholecystectomy versus single-fulcrum laparoscopic cholecystectomy: Which minimally invasive surgery is better?

Backgrounds/Aims: In recent years, many minimally invasive techniques have been introduced to reduce the number of ports in laparoscopic cholecystectomy (LC), offering benefits such as reduced postoperative pain and improved cosmetic outcomes. ArtiSential® is a new multi-degree-of-freedom articulating laparoscopic instrument that incorporates the ergonomic features of robotic surgery, potentially overcoming the spatial limitations of laparoscopic surgery. ArtiSential® LC can be performed using only two ports. This study aims to compare the surgical outcomes of ArtiSential® LC with those of single-fulcrum LC. Methods: This retrospective study compared ArtiSential® LC and single-fulcrum LC among LCs performed for gallbladder (GB) stones at the same center, analyzing the basic characteristics of patients; intraoperative outcomes, such as operative time, estimated blood loss, and intraoperative GB rupture; and postoperative outcomes, such as length of hospital stay, incidence of postoperative complications, and postoperative pain. Results: A total of 88 and 63 patients underwent ArtiSential® LC and single-fulcrum LC for GB stones, respectively. Analysis showed that ArtiSential® LC resulted in significantly fewer cases of surgeries longer than 60 minutes (30 vs. 35 min, p = 0.009) and intraoperative GB ruptures (2 vs. 10, p = 0.007). In terms of postoperative outcomes, ArtiSential® LC showed better results in the respective visual analog scale (VAS) scores immediately after surgery (2.59 vs. 3.73, p < 0.001), and before discharge (1.44 vs. 2.02, p = 0.01). Conclusions: ArtiSential® LC showed better results in terms of surgical outcomes, especially postoperative pain. Thus, ArtiSential® LC is considered the better option for patients, compared to single-fulcrum LC.

Updated practice guideline for dual-energy X-ray absorptiometry (DXA).

The introduction of dual-energy X-ray absorptiometry (DXA) technology in the 1980s revolutionized the diagnosis, management and monitoring of osteoporosis, providing a clinical tool which is now available worldwide. However, DXA measurements are influenced by many technical factors, including the quality control procedures for the instrument, positioning of the patient, and approach to analysis. Reporting of DXA results may be confounded by factors such as selection of reference ranges for T-scores and Z-scores, as well as inadequate knowledge of current standards for interpretation. These points are addressed at length in many international guidelines but are not always easily assimilated by practising clinicians and technicians. Our aim in this report is to identify key elements pertaining to the use of DXA in clinical practice, considering both technical and clinical aspects. Here, we discuss technical aspects of DXA procedures, approaches to interpretation and integration into clinical practice, and the use of non-bone mineral density measurements, such as a vertebral fracture assessment, in clinical risk assessment.

Segmental root development of immature necrotic permanent teeth following regenerative endodontic procedures: a case series.

Regenerative endodontic procedures (REPs) are frequently utilized to treat immature permanent teeth with necrotic or inflamed pulps. In most instances, these treatments successfully result in the resolution of apical periodontitis and continued root maturation. However, after reviewing over 180 REP cases treated in the Endodontics Department of Stomatology Hospital at Zhejiang University School of Medicine over the past seven years, we identified an unusual root development pattern in ten cases, characterized by root tips detached from the root body. We conducted a comprehensive analysis of the patients' demographic information, dental histories, and therapeutic efficacy, and identified five potential etiological factors for this rare phenomenon, including external force, prolonged extensive periapical inflammation, iatrogenic factors, traumatic history of primary teeth, and excessive tooth mobility. In our study, we observed that therapeutic failure was more likely in patients with initially separated root tips, while those with initially normal teeth demonstrated significantly better prognoses. We hypothesize that the initial root condition may exert a considerable influence on treatment outcomes.
