Successful laparoscopic retroperitoneal tumor resection using mixed reality and guiding marker techniques.

Introduction: Small tumors may be difficult to identify visually and require preoperative effort to locate. Recent advancements in mixed reality technology have improved surgical accuracy in various departments. Here, we present the application of mixed reality-assisted surgery and a guiding marker in the case of small retroperitoneal metastasis of uterine cancer.

Immunohistochemical localization of HCA1 receptor in placenta in presence of fetal growth restriction.

Introduction: Glucose metabolism produces lactate and hydrogen ions in an anaerobic environment. Fetuses with intrauterine growth restriction are considered to become progressively lactacidemic as well as hypoxic. Roles of lactate in the placenta in the presence of fetal growth restriction (FGR) remain to be clarified.

Immunological disease activity parameters at conception are risk factors for preterm birth and low birth weight in patients with systemic lupus erythematosus.

Objective: This study aimed to identify which disease activity parameters may be risk factors for preterm birth (PB) and low birth weight (LBW) in patients with systemic lupus erythematosus (SLE). We also analyzed the extent to which these parameters affected PB and LBW.

Methods: We collected the SLE Disease Activity Index (SLEDAI), the rate of lupus low disease activity state (LLDAS) attainment, complement levels, and the titer of anti-double stranded DNA (dsDNA) antibody as disease activity parameters.

A retrospective study of locally advanced cervical cancer cases treated with CT-based 3D-IGBT compared with 2D-IGBT.

Purpose: To retrospectively review locally advanced cervical cancer (CC) cases treated with three-dimensional image-guided brachytherapy (3D-IGBT) and two-dimensional (2D)-IGBT.

Materials And Methods: Patients with Stage IB-IVa CC who underwent intracavitary irradiation between 2007 and 2021 were divided into the 3D-IGBT and 2D-IGBT groups. Local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), overall survival (OS), and gastrointestinal toxicity (G3 or more) were investigated at 2/3 years post-treatment.

Pregnancy course and outcomes of patients with polymyositis and dermatomyositis (PM/DM) managed in a single center.

We aimed to determine the association between disease activity during pregnancy and pregnancy outcomes of women with polymyositis and dermatomyositis (PM/DM). Patients with PM/DM who were managed from pregnancy to delivery at Kagawa University Hospital from March 2006 to May 2021 were enrolled. Clinical data were retrospectively analyzed to evaluate the association between disease activity during pregnancy and pregnancy outcomes.
