Problems of magnetic resonance diagnosis for gastric-type mucin-positive cervical lesions of the uterus and its solutions using artificial intelligence.

Purpose: To reveal problems of magnetic resonance imaging (MRI) for diagnosing gastric-type mucin-positive (GMPLs) and gastric-type mucin-negative (GMNLs) cervical lesions.

Methods: We selected 172 patients suspected to have lobular endocervical glandular hyperplasia; their pelvic MR images were categorised into the training (n = 132) and validation (n = 40) groups. The images of the validation group were read twice by three pairs of six readers to reveal the accuracy, area under the curve (AUC), and intraclass correlation coefficient (ICC).

Limited diagnostic performance of imaging evaluation for staging in gastric-type endocervical adenocarcinoma: a multi-center study.

Purpose: The purposes of the study are to assess the diagnostic performance of preoperative imaging for staging factors in gastric-type endocervical adenocarcinoma (GEA) and to compare the performance for GEA with that of usual-type endocervical adenocarcinoma (UEA) among patients preoperatively deemed locally early stage (DLES) (< T2b without distant metastasis).

Materials And Methods: For this multi-center retrospective study, 58 patients were enrolled. All had undergone MRI with or without CT and FDG PET-CT preoperatively and had been pathologically diagnosed with GEA at five institutions.

A case of primary ciliary dyskinesis with DRC1 deletion and literature review: Additional evidence on the founder effect.

Background: Primary ciliary dyskinesia (PCD) is a rare genetic disease caused by defects in various genes affecting ciliary function. It is currently unclear why DRC1 gene variants are a relatively frequent cause of disease in Japanese and Korean patients.

Methods: A 12-year-old Japanese girl with bronchiectasis was suspected of PCD and examined using whole-exome sequencing (WES).

MR diagnosis of SCC arising within ovarian cystic teratomas: analysis of mural nodule characteristics.

Purpose: This study aims to evaluate and identify magnetic resonance (MR) findings of mural nodules to detect squamous cell carcinoma arising from ovarian mature cystic teratoma (SCC-MCT).

Methods: This retrospective study examined 135 patients (SCC-MCTs, n = 12; and benign MCTs, n = 123) with confirmed diagnoses across five different institutions between January 2010 and June 2022. Preoperative MR images for each patient were independently assessed by two experienced radiologists and analyzed following previously reported findings (PRFs): age, tumor size, presence of mural nodules, size of mural nodule, and the angle between mural nodule and cyst wall (acute or obtuse).

Coronavirus or Cholangitis? An Acute Necrotizing Encephalopathy Caused by COVID-19.

A 63-year-old Japanese woman presented to the emergency room with a fever and altered mental status. She was diagnosed as acute cholangitis and coronavirus disease 2019 (COVID-19). On the second day, her consciousness level deteriorated.

Comparative characteristics between calyculin A-induced and thimerosal-induced hyperactivation of cryopreserved bovine spermatozoa.

This study aimed to characterize calyculin A (CL-A)-induced and thimerosal-induced hyperactivation of cryopreserved bovine spermatozoa. Hyperactivation was effectively induced by treating with 10 nM CL-A for 60 min in the presence of cyclic AMP analogs, extracellular Ca, and albumin or with 12.5 µM thimerosal briefly in the absence of these capacitation-supporting factors.

Diagnosis and treatment approaches for simultaneous onset of subarachnoid hemorrhage and thyroid storm: a case report.

Background: Subarachnoid hemorrhage and thyroid storm are similar in their clinical symptomatology, and diagnosis of these conditions, when they occur simultaneously, is difficult. Here, we report a rare case of concurrent subarachnoid hemorrhage and thyroid storm we encountered at our hospital.

Case Presentation: The patient was a 52-year-old woman.

Prolonged mechanical ventilation in patients with severe COVID-19 is associated with serial modified-lung ultrasound scores: A single-centre cohort study.

Lung ultrasound (LUS), a rapid, bedside, goal-oriented diagnostic test, can be quantitatively assessed, and the scores can be used to evaluate disease progression. However, little data exists on predicting prolonged mechanical ventilation (PMV) and successful extubation using serial LUS scores. We examined the relationship of PMV with successful extubation in patients with severe coronavirus disease (COVID-19) by using two types of serial LUS scores.

A cross-sectional examination of the simultaneous association of four emotion regulation strategies with abnormal eating behaviours among women in Japan.

Background: Research has suggested an association between emotion regulation strategies (ERSs) and abnormal eating behaviours/attitudes (AEB), and many studies have examined the association of one particular ERS with AEB. Additionally, different ERSs are reported to be strongly correlated with each other. Therefore, the associations between an individual ERS and AEB, reported previously, may be spurious.

Usefulness of the 'cosmos pattern' for differentiating between cervical gastric-type mucin-positive lesions and other benign cervical cystic lesions in magnetic resonance images.

Aim: To evaluate the usefulness of the 'cosmos pattern' (CP) on magnetic resonance (MR) images for differentiating between gastric-type mucin-positive lesions (GMPL) and gastric-type mucin-negative lesions (GMNL).

Methods: This study included 131 patients with clinical suspicion of lobular endocervical glandular hyperplasia (LEGH) who underwent pelvic MR imaging and a Pap smear and/or latex agglutination assay. Differences in MR findings, such as cyst and solid component patterns, cervical location and T1-weighted image (T1WI) signal intensity, were compared between GMPL and GMNL.

Limited frequency of malignant change in lobular endocervical glandular hyperplasia.

Introduction: Although lobular endocervical glandular hyperplasia is a benign disorder of the uterine cervix, its potential as a precursor of minimal deviation adenocarcinoma has been reported. However, the natural history of the disease and the frequency of malignant change are not fully understood. We evaluated the frequency of malignant change of clinical lobular endocervical glandular hyperplasia and explored useful parameters indicating malignant change.

A report of the Social Vital Signs Workshop at WONCA Asia Pacific Regional Conference 2019.

We, Team SAIL, held the workshop at WONCA APR Conference 2019 for presenting the concept of Social Vital Signs (SVS) to an international audience.

Worsening cytology and lesion enlargement are useful indicators for malignant transformation of lobular endocervical glandular hyperplasia during follow-up: A case report.

•We report a case of MDA arising from clinical LEGH during 5 years of follow-up.•The first sign suggesting MDA was cellular atypia in endocervical cytology, and was followed by an increase in tumor size.•MDA lesion lacked in stromal reaction and MRI failed to detected MDA.

Effect of body mass index on surgical times of lumbar laminoplasty and lower limb arthroplasties.

Background: Obesity is an important factor affecting incidence and development of musculoskeletal degenerative changes. In addition, obese patients are considered less favorable surgical candidates for decompression surgery in degenerative lumbar spinal canal stenosis and lower limb arthroplasty. The purpose was to assess disease characteristics of lumbar spinal canal stenosis as well as lower limb osteoarthritis, and to investigate surgical times based on body mass index (BMI) in lumbar decompressive surgery and lower limb arthroplasties.

Evaluation of hemodynamic imaging findings of hypervascular hepatocellular carcinoma: comparison between dynamic contrast-enhanced magnetic resonance imaging using radial volumetric imaging breath-hold examination with k-space-weighted image contrast reconstruction and dynamic computed tomography during hepatic arteriography.

Purpose: To compare the visualization of hemodynamic imaging findings of hypervascular hepatocellular carcinoma (HCC) on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) using radial volumetric imaging breath-hold examination with k-space-weighted image contrast reconstruction (r-VIBE-KWIC) versus dynamic computed tomography during hepatic arteriography (dyn-CTHA).

Materials And Methods: We retrospectively reviewed the databases of preoperative DCE-MRI using r-VIBE-KWIC, dyn-CTHA, and postoperative pathology of resected specimens. Fourteen patients with 14 hypervascular HCCs underwent both DCE-MRI and dyn-CTHA.
