Purpose: To evaluate the efficacy and safety of slanted bilateral lateral rectus recession (BLR-rec) for treating convergence insufficiency-type intermittent exotropia (CI-IXT) in children.

Methods: In this retrospective cohort study, 26 patients aged <16 years with CI-IXT who underwent BLR-rec between August 2016 and July 2021 with six months of follow-up data post-surgery were classified into slanted BLR-rec group (n = 14) and standard BLR-rec group (n = 12; equal-length recession of the upper and lower horns of the LR muscle). Surgical outcomes were compared between the groups.

Background: Differences in the effects of cream-type denture adhesives and home liners remain unclear.

Objective: This cross-sectional study aimed to clarify the differences in the oral-hygiene status and masticatory performance between participants using cream-type denture adhesives and those using home liners.

Methods: Masticatory performance with and without cream-type denture adhesives and home liners was evaluated using colour-changeable chewing gum.

Introduction: In certain cases of rectal malignancy in which invasion is confined to the prostate and/or seminal vesicles, bladder-sparing surgery may be chosen instead of total pelvic exenteration. However, even if the bladder is preserved, postoperative urinary dysfunction and vesicourethral anastomotic leakage are concern.

Materials And Surgical Technique: We employ various techniques based on robot-assisted radical prostatectomy for reconstructing the urinary tract.

Purpose: Despite the efficacy of endorectal balloon (ERB) in reducing rectal radiation dose, the effectiveness of upper rectal fixation remains to be evaluated. The purpose of this study was to evaluate the impact of ERB on upper rectal fixation in patients diagnosed with localized prostate cancer.

Materials: Cine MRI was performed in 46 patients with localized prostate cancer to assess the stability of the anterior rectal wall with and without ERB by calculating the standard deviation of the normalized signal intensity at the level of the midgland or the seminal vesicle.
