Side-to-side differences in hip bone mineral density in patients with unilateral hip osteoarthritis.

Background: Accurately evaluating bone mineral density (BMD) in patients with unilateral hip osteoarthritis (OA) is crucial for diagnosing osteoporosis and selecting implants for hip arthroplasty. Our goal was to measure the BMD differences between sides, examine contributing factors, and identify the optimal side for BMD assessment in these patients.

Methods: We analyzed 108 women with unilateral hip OA.

Double-seropositive Myasthenia Gravis Following COVID-19: A case report.

Myasthenia gravis (MG) is an autoimmune disease characterized by muscle weakness caused by antibodies targeting acetylcholine receptors (AChRs) or muscle-specific kinases (MuSK). Double-seropositive MG (DSP-MG) caused by both antibodies is rare. We herein report a 78-year-old woman who developed DSP-MG after COVID-19 infection.

Depth of submucosal invasion vs. Haggitt level as prognostic predictors of pedunculated‑type early‑stage colorectal cancer removed by endoscopic resection.

Additional surgery is considered when deep submucosal (SM) invasion (≥1,000 µm) is pathologically observed following the endoscopic resection of early-stage colorectal cancer (eCRC). The Japanese Society for Cancer of the Colon and Rectum (JSCCR) states that the depth of SM invasion be measured from the lower border of the muscularis mucosae (MM) when MM can be identified/estimated and from the lesion's surface when it cannot, irrespective of macroscopic types. In MM-tangled pedunculated eCRC cases, SM invasion depth should be measured from the reference line, which is the boundary between the tumor head and stalk.

Volume and quality of the gluteal muscles are associated with early physical function after total hip arthroplasty.

Purpose: Identifying muscles linked to postoperative physical function can guide protocols to enhance early recovery following total hip arthroplasty (THA). This study aimed to evaluate the association of preoperative pelvic and thigh muscle volume and quality with early physical function after THA in patients with unilateral hip osteoarthritis (HOA).

Methods: Preoperative Computed tomography (CT) images of 61 patients (eight males and 53 females) with HOA were analyzed.

Medication use and risk of reflux oesophagitis.

Objective: Reflux oesophagitis (RO) is one of the most common diseases encountered by gastroenterologists and primary care physicians. However, few epidemiological studies have investigated the association of medication use and RO. This study aimed to investigate the prevalence of RO and its risk factors, particularly with respect to medication use.

Utility of Orthosis in the Conservative Treatment of Proximal Phalanx Fractures: A Preliminary Study in Healthy Participants.

Background: The standard treatment for the conservative management of a proximal phalanx fracture of the little finger involves immobilizing the fracture site with a cast. However, cast immobilization presents challenges in maintaining hygiene during treatment and restricts the fine motor movements of the fingers. In this study, we developed a removable orthosis that immobilizes only the ring and little fingers.

Clinical course of masticatory function recovery following endoscopic-assisted open reduction and internal fixation in patients with unilateral mandibular condyle fracture.

The purpose of this study was to investigate the clinical course of masticatory function recovery following an endoscopic-assisted open reduction and internal fixation (EAORIF) procedure. Patients with a unilateral mandibular condylar fracture who underwent EAORIF for therapeutic purposes were evaluated, with comparisons made between those who underwent the procedure for base or neck fractures. At each time point analyzed after treatment, the occlusal contact area and maximum bite force in patients with a base fracture were greater, although the differences between the groups were not significant.

Background: Esophageal cancer is one of the most common types of cancer in Japan. Herein, we report the efficacy and safety of E7389-LF plus the immune checkpoint inhibitor, nivolumab, from the esophageal cancer cohort of the phase 2 part of Study 120.

Methods: Eligible patients received E7389-LF 2.

Artificial intelligence-based analysis of lower limb muscle mass and fatty degeneration in patients with knee osteoarthritis and its correlation with Knee Society Score.

Purpose: Lower-limb muscle mass reduction and fatty degeneration develop in patients with knee osteoarthritis (KOA) and could affect their symptoms, satisfaction, expectation and functional activities. The Knee Society Scoring System (KSS) includes patient reported outcome measures, which is widely used to evaluate the status of knee function of KOA. This study aimed to clarify how muscle mass and fatty degeneration of the lower limb correlate with the KSS in patients with KOA.

Surgery-early approach combined with condylectomy for correction of severe facial asymmetry with mandibular condylar hyperplasia: a case report.

In patients with unilateral mandibular condyle hyperplasia, whether to perform condylectomy and orthognathic surgical procedures at the same time or orthognathic surgery in two stages for remains controversial. Reported here is a case of facial asymmetry with mandibular condyle hyperplasia, for which condylectomy and orthognathic surgery procedures were performed at the same time. A 28-year-old woman was presented to our department with chief complaints of left deviation of the mandible and right temporomandibular joint (TMJ) noise.

Enfortumab Vedotin-Induced Febrile Neutropenia and Hyperglycemia Successfully Treated with Multidisciplinary Treatment Including Continuous Hemodialysis Filtration and Insulin Injection in a Patient with Chemo-Resistant Metastatic Urothelial Carcinoma: A Case Report.

Introduction: Enfortumab vedotin (EV) is an antibody-drug conjugate combining a monoclonal antibody targeting nectin-4 with a highly potent microtubule disrupting agent. EV is expected to be a candidate for the third-line treatment for urothelial carcinoma previously treated with platinum-based chemotherapy and PD-1/PD-L1 inhibitors. Very few cases of patients experienced hyperglycemia of unknown cause.

Effects of Food, Gastric Acid Reduction, and Strong CYP3A Induction on the Pharmacokinetics of Tasurgratinib, a Novel Selective Fibroblast Growth Factor Receptor Inhibitor.

We conducted this three-part study in healthy subjects to investigate the pharmacokinetics of tasurgratinib (orally available selective inhibitor of fibroblast growth factor receptor 1-3) and M2 (its major metabolite) under different conditions. In Part A, subjects received tasurgratinib 35 mg either fed with a high-fat meal or fasted. In Parts B and C, subjects received tasurgratinib 35 mg alone or with either rabeprazole (acid-reducing agent) 20 mg (Part B) or rifampin (strong CYP3A inducer) 600 mg (Part C).

Imaging Features of Uncommon Entities That Manifest with Torsion.

Torsion is the twisting of an object along the axis, and various structures (organs and tumors) in the body can twist. Torsion causes initial lymphatic and venous outflow obstruction, leading to congestive edema, enlargement, venous hemorrhagic infarction, and surrounding edema. It can also cause subsequent arterial obstruction depending on the degree of torsion, leading to ischemia, infarction, necrosis, gangrene, and surrounding inflammation.

Prevalence and Risk Factors of Constipation Symptoms among Patients Undergoing Colonoscopy: A Single-Center Cross-Sectional Study.

Introduction: Constipation is one of the most common gastrointestinal symptoms. It may compromise quality of life and social functioning and result in increased healthcare use and costs. We aimed to evaluate the prevalence and risk factors of constipation symptoms, as well as those of refractory constipation symptoms among patients who underwent colonoscopy.

Automatic detection of midfacial fractures in facial bone CT images using deep learning-based object detection models.

Background: Midfacial fractures are among the most frequent facial fractures. Surgery is recommended within 2 weeks of injury, but this time frame is often extended because the fracture is missed on diagnostic imaging in the busy emergency medicine setting. Using deep learning technology, which has progressed markedly in various fields, we attempted to develop a system for the automatic detection of midfacial fractures.

Effect of rechallenge nivolumab in a hemodialysis patient with multiple metastases from a rapidly progressed T1a renal clear cell carcinoma: An autopsy case.

Introduction: Distant metastasis of T1a renal cell carcinoma is rare and whether metastasis is more probable in patients undergoing hemodialysis remains unclear. We report the autopsy case of a patient undergoing hemodialysis with multiple metastases that rapidly progressed from T1a renal cell carcinoma treated with multimodal therapy including nivolumab.

Case Presentation: A 70-year-old male who underwent hemodialysis was diagnosed with clear cell carcinoma (pT1a, G2) after nephrectomy.

Magnetic resonance imaging features of complete androgen insensitivity syndrome in comparison to Mayer-Rokitansky-Küster-Hauser syndrome.

Purpose: Complete androgen insensitivity syndrome (CAIS) and Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) share common clinical features such as female phenotype, vaginal hypoplasia, and primary amenorrhea. Magnetic resonance imaging (MRI) is performed to investigate the cause of primary amenorrhea. However, the MRI features are also similar in both disorders.
