Novel Fixable Instruments Used in Strabismus Surgery.

J Pediatr Ophthalmol Strabismus

Published: November 2024

Purpose: To introduce the application of novel fixable instruments in strabismus surgery without surgical assistants.

Methods: Patients with strabismus requiring surgical treatment were recruited. Under general anesthesia all patients underwent surgery with the three novel kinds of fixable instruments without assistants. The operation time of each muscle was recorded separately.

Results: A total of 30 patients were enrolled in this study. There were 34 lateral rectus muscles, 22 medial rectus muscles, 2 superior rectus muscles, 2 inferior rectus muscles, and 14 inferior oblique muscles. The amount of recession and resection of the lateral rectus muscle was 6 to 11 and 4 to 6 mm, respectively, and the operation time of each muscle was between 8 and 12 minutes (mean ± standard deviation: 9.88 ± 1.59 minutes). The amount of recession and resection of the medial rectus muscle was 5 to 6.5 and 4 to 6 mm, respectively, and the operation time of each muscle was 7 to 14 minutes (mean ± standard deviation: 10.59 ± 2.38 minutes). Two superior rectus muscles were recessed 7 and 9 mm and the operation time was 8 and 10 minutes, respectively. Two inferior rectus muscles were recessed 4 and 5 mm and the operation time was 7 and 9 minutes, respectively. In addition, the operation time of each oblique muscle was 6 to 10 minutes (mean ± standard deviation: 8.57 ± 1.40 minutes). All patients recovered ocular alignment with no adverse reaction in eyes on the first day after surgery.

Conclusions: With the assistance of the novel fixable instruments, the surgeon can easily perform routine strabismus surgeries even without surgical assistants. .

Background: Kidney tumors, common in the urinary system, have widely varying survival rates post-surgery. Current prognostic methods rely on invasive biopsies, highlighting the need for non-invasive, accurate prediction models to assist in clinical decision-making.

Purpose: This study aimed to construct a K-means clustering algorithm enhanced by Transformer-based feature transformation to predict the overall survival rate of patients after kidney tumor resection and provide an interpretability analysis of the model to assist in clinical decision-making.

Rib pathology is uniquely difficult and time-consuming for radiologists to diagnose. AI can reduce radiologist workload and serve as a tool to improve accurate diagnosis. To date, no reviews have been performed synthesizing identification of rib fracture data on AI and its diagnostic performance on X-ray and CT scans of rib fractures and its comparison to physicians.

Objective: To explore the efficacy and safety of the direct inferior endplate approach in percutaneous endoscopic interlaminar discectomy (PEID) for the treatment of L5-S1 disc herniation.

Methods: This was a retrospective analysis of 116 patients with L5-S1 disc herniation treated with PEID; 74 patients underwent surgery via the direct inferior endplate approach (group A), and 42 patients underwent surgery via the indirect approach (group B). The number of intraoperative fluoroscopy exposures, establishment channel time, operation time, postoperative visual analogue scale (VAS) score, and Oswestry Disability Index (ODI) were compared between the 2 groups.

Department of Breast Surgery, Thyroid Surgery, Huangshi Central Hospital, Affiliated Hospital of Hubei Polytechnic University, No.141, Tianjin Road, Huangshi, 435000, Hubei, China.

Background: The heterogeneity of breast cancer (BC) necessitates the identification of novel subtypes and prognostic models to enhance patient stratification and treatment strategies. This study aims to identify novel BC subtypes based on PANoptosis-related genes (PRGs) and construct a robust prognostic model to guide individualized treatment strategies.

Methods: The transcriptome data along with clinical data of BC patients were sourced from the TCGA and GEO databases.

Relationship between intraoperative blood pressure variability and postoperative acute kidney injury in pediatric cardiac surgery.

Pediatr Nephrol

Department of Anesthesiology, West China Hospital, Sichuan University, No. 37 Guoxue Lane, Wuhou District, Chengdu, 610000, Sichuan, China.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a notably common complication in pediatrics, with an incidence rate ranging from 15 to 64%. This rate is significantly higher than that observed in adults. Currently, there is a lack of substantial evidence regarding the association between intraoperative blood pressure variability (BPV) during cardiac surgery with cardiopulmonary bypass (CPB) and the development of AKI in pediatric patients.
