Medication-based profiling of older orthopedic patients: a multicenter cross-sectional study.

Background: Managing medication use in older orthopedic patients is imperative to extend their healthy life expectancy in an aging society. However, the actual situation regarding polypharmacy, the intake of potentially inappropriate medications (PIMs), and fall risk-increasing drugs (FRIDs) among older orthopedic patients is not well characterized. This study aimed to investigate the medication-based profiles of older orthopedic patients to highlight the critical points of concern.

Prediction Model for Severe Thrombocytopenia Induced by Gemcitabine Plus Cisplatin Combination Therapy in Patients with Urothelial Cancer.

Background: Chemotherapy-induced thrombocytopenia is often a use-limiting adverse reaction to gemcitabine and cisplatin (GC) combination chemotherapy, reducing therapeutic intensity, and, in some cases, requiring platelet transfusion.

Objective: A retrospective cohort study was conducted on patients with urothelial cancer at the initiation of GC combination therapy and the objective was to develop a prediction model for the incidence of severe thrombocytopenia using machine learning.

Methods: We performed receiver operating characteristic analysis to determine the cut-off values of the associated factors.

COVID-19 mRNA vaccination is associated with IgA nephropathy: an analysis of the Japanese adverse drug event report database.

Coronavirus disease 2019 (COVID-19) mRNA vaccines are used worldwide to prevent severe symptoms of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. IgA nephropathy (IgAN) is the most common form of glomerular injury after COVID-19 vaccination; however, because of the low frequency of such events, only a few reports have been published. A large pharmacovigilance database of real-world spontaneous adverse event (AE) reports is essential for evaluating the drug-associated safety signals regarding rare AEs.

A rare case of sacral epidural arteriovenous fistula with concomitant occult multiple lumbar epidural arteriovenous fistulas.

We describe a rare case of sacral epidural arteriovenous fistulas (edAVFs) with atypical clinical course of treatment. A 78-year-old man with a history of spinal surgery presented progressive gait disturbance and urinary incontinence. Spinal angiography demonstrated a sacral spinal AVF fed by bilateral lateral sacral arteries, draining to the venous pouch with subdural drainage.

Transrenal Ureter Embolization for Refractory Urine Leaks from Iatrogenic Ureteric Injury Following Colorectal Surgery.

We present the cases of two patients who underwent ureteral occlusion using coils and/or Amplatzer Vascular Plug with N-butyl cyanoacrylate glue after extensive advanced rectal surgery. Both patients had complex urine leaks unresponsive to urinary diversion. In view of the progress of the disease and the history of polysurgery, reconstructive surgery or anterograde ureteral stent insertion was not chosen.

A Rare Case of Cervical Myelopathy Caused by an Anomaly of the Axis: A Case Report and a Review of Current Comprehensive Literature.

Introduction: Cervical myelopathy due to anomalies of the posterior elements of the axis is rare, and limited cases have been reported. This study reports such a unique case of congenital anomaly of the laminae of the axis, which is treated by partial removal of the anomalous bony structure surgically, and provides a comprehensive review of the present literature on this pathological condition.

Case Presentation: A 65-year-old man presented with a 3-year history of numbness in both arms with a sensory change in the right arm.

Frequency of Immune Checkpoint Inhibitor-Induced Vasculitides: An Observational Study Using Data From the Japanese Adverse Drug Event Report Database.

Information on immune checkpoint inhibitor-induced vasculitides is limited, and predictors for this condition have not been identified. Therefore, we have examined the frequency of immune checkpoint inhibitor-induced vasculitides by analyzing the data recorded in the Japanese Adverse Drug Event Report database. Data from April 2004 to March 2020 were extracted, and vasculitides as an immune-related adverse event was defined according to the 2012 revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides.

Surgical Management of Thoracolumbar Scoliosis Secondary to Hip Joint Ankylosis and Severe Pelvic Obliquity.

We report a rare case of a rigid spinal deformity with severe pelvic obliquity (PO) resulting from hip ankylosis caused by childhood tuberculosis (TB). A 66-year-old woman presented with left knee pain, chronic low back pain, and fatigability during walking. She presented with leg length discrepancy (LLD) due to an ankylosed right hip joint, severe PO, and secondary lumbar scoliosis.

Prospective cohort study on the incidence and risk factors of emergency home visits among Japanese home care patients.

Background: Population aging requires more physician home visits, and various measures need to be taken to reduce the burden on visiting physicians. However, the incidence and associated factors of burdensome emergency home visits remain unclear. We aimed to reveal the incidences of emergency home visits among cancer and noncancer patients and examine how visiting nurses affect those.

Concomitant Proton Pump Inhibitors and Immune Checkpoint Inhibitors Increase Nephritis Frequency.

Background/aim: Concomitant proton pump inhibitor (PPI) and immune checkpoint inhibitor (ICPI) were determined as risk factors of acute kidney injury. To identify the type of PPI associated with ICPI-induced nephritis, we used the Japanese Adverse Drug Event Report database.

Patients And Methods: ICPIs (nivolumab, pembrolizumab, ipilimumab, atezolizumab, durvalumab, and avelumab) and PPIs (esomeprazole, omeprazole, vonoprazan, rabeprazole, and lansoprazole) were selected as suspected nephritis-inducing drugs.

Surgical procedures for the prevention of extension-flexion gap imbalance in total knee arthroplasty.

The purpose of this study was to identify preoperative and intraoperative factors that influence extension-flexion gap imbalance in total knee arthroplasty (TKA). Ninety-three knees undergoing TKA with the modified gap balancing technique were included. Preoperative range of motion, intraoperative extension-flexion gap balance, thickness of the resected bone and radiological parameters were investigated.
