A Case of Paraneoplastic Neurological Syndrome Associated with Breast Cancer Detected while Searching for the Cause of Involuntary Movement.

Our case involved a 66-year-old woman who noticed progressive asymmetric involuntary movement, difficulty speaking, and difficulty swallowing. The patient fractured her femur due to a lower extremity involuntary movement while walking. During the course of her treatment for the fracture, her neurological symptoms worsened.

Japanese Nationwide Comparative Survey of Medication Guidance Provided by Certified and Uncertified Palliative Care Pharmacists.

Background: As members of a medical team, pharmacists are expected to provide optimal patient-centered, evidence-based pharmacotherapy. In Japan, in consideration of the importance of palliative care, a system was initiated for certifying palliative care pharmacists in 2010. However, no studies have evaluated the usefulness of board certification in palliative pharmacy.

Cerebral response to emotional working memory based on vocal cues: an fNIRS study.

Introduction: Humans mainly utilize visual and auditory information as a cue to infer others' emotions. Previous neuroimaging studies have shown the neural basis of memory processing based on facial expression, but few studies have examined it based on vocal cues. Thus, we aimed to investigate brain regions associated with emotional judgment based on vocal cues using an N-back task paradigm.

Impact of the COVID-19 pandemic on prehospital and in-hospital treatment and outcomes of patients after out-of-hospital cardiac arrest: a Japanese multicenter cohort study.

Background: In the chain of survival for Out-of-hospital cardiac arrest (OHCA), each component of care contributes to improve the prognosis of the patient with OHCA. The SARS-CoV-2 (COVID-19) pandemic potentially affected each part of care in the chain of survival. The aim of this study was to compare prehospital care, in-hospital treatment, and outcomes among OHCA patients before and after the COVID-19 pandemic.

Distribution of Splenic Arterial Flow and Segmental Spleen Volume for Partial Splenic Arterial Embolization.

Introduction: The spleen is a lymphatic organ that manages immune surveillance of the blood, produces blood cells, and helps filter the blood, remove old blood cells, and fight infection. The normal splenic weight is approximately 65-265 g. This study evaluated spleen volume and segmental volume.

Usefulness of Self-Selected Scenarios for Simple Triage and Rapid Treatment Method Using Virtual Reality.

Background: Repeated triage training is necessary to maintain and improve the accuracy of simple triage and rapid treatment (START), a popular triage method. Virtual reality (VR) may be more effective than conventional training methods. This study aimed to verify the educational usefulness of START using VR originally developed for students.

Prognostic Significance of Signs of Life in Out-of-Hospital Cardiac Arrest Patients Undergoing Extracorporeal Cardiopulmonary Resuscitation.

Objectives: Signs of life (SOLs) during cardiac arrest (gasping, pupillary light reaction, or any form of body movement) are suggested to be associated with favorable neurologic outcomes in out-of-hospital cardiac arrest (OHCA). While data has demonstrated that extracorporeal cardiopulmonary resuscitation (ECPR) can improve outcomes in cases of refractory cardiac arrest, it is expected that other contributing factors lead to positive outcomes. This study aimed to investigate whether SOL on arrival is associated with neurologic outcomes in patients with OHCA who have undergone ECPR.

Comparison of Analgesic Efficacy and Safety of Low-Dose Transdermal Fentanyl and Oral Oxycodone in Opioid-Naïve Patients with Cancer Pain.

In Japan, a low-dose transdermal fentanyl (TDF; 0.5 mg) has been approved to address pain in opioid-naïve patients with cancer; however, efficacy and safety data are lacking. To determine the efficacy and safety of TDF, patients with opioid-naïve cancer pain prescribed TDF (0.

Prognostic impact of postoperative infection after resection of biliary malignancy: A multicenter retrospective cohort study.

Background: The aim of this study was to investigate the prognostic impact of postoperative infections in patients who underwent resection for biliary malignancy, including intrahepatic cholangiocarcinoma, perihilar cholangiocarcinoma, distal cholangiocarcinoma, gallbladder carcinoma, and carcinoma of the ampulla of Vater.

Methods: This study was conducted in an 11-center retrospective cohort study. Patients with biliary tract cancer who underwent curative resection between April 2013 and March 2015 at 11 institutions in Japan were enrolled.

Minimal effective dose of maintenance steroid therapy for relapse of cryptogenic organizing pneumonia.

Background: Long-term maintenance steroid therapy (MST) is frequently required for repeated relapses of cryptogenic organizing pneumonia (COP); however, the optimal minimal dose has not been clarified. Therefore, this study evaluated the minimal MST dose required to prevent repeated relapses and identify relapse predictors.

Methods: We retrospectively reviewed the medical records of patients with steroid-treated COP and compared background factors between the non-relapse and relapse groups.

Characteristics of healthy Japanese young adults with respect to recognition of facial expressions: a preliminary study.

Background: Emotional cognitive impairment is a core phenotype of the clinical symptoms of psychiatric disorders. The ability to measure emotional cognition is useful for assessing neurodegenerative conditions and treatment responses. However, certain factors such as culture, gender, and generation influence emotional recognition, and these differences require examination.

AQUACEL® Ag Advantage reduces the stress of postoperative packing removal after endoscopic sinus surgery.

Objective: After Endoscopic Sinus Surgery (ESS), packing plays an important role in wound healing and hemostasis. However, the effect of the packing removal procedure on physician stress has not been evaluated. The purpose of this study was to evaluate physician stress during packing removal for patients treated with AQUACEL® Ag Advantage versus KALTOSTAT®.

Development of eosinophilic pneumonia from eosinophilic bronchiolitis without asthma: A case report.

Eosinophilic bronchiolitis is a disease concept reported in Japan in 2001, that presents with bronchiolitis accompanied by eosinophilia in the blood and lungs. In 2013, hypereosinophilic obliterative bronchiolitis, as a group of disease presenting with eosinophilic bronchiolitis, was proposed in France. The relationship between eosinophilic bronchiolitis and other eosinophil-related diseases has not been clarified.

Evaluation of odor recognition threshold measurement methods in T&T olfactometry: A survey study.

Objective: The odor recognition thresholds in T&T olfactometry are measured by either the examiner's judgment of the patients' odor expression for each standard odor or by the patient's choice of the correct response from an olfactory term table. This study aimed to clarify the correct odor expressions and use of the olfactory term table.

Methods: A questionnaire was administered to otolaryngologists or medical staff in charge of testing at facilities where T&T olfactometry is performed.

Evaluation of splenic infarction ratio and platelet increase ratio after partial splenic artery embolization.

Objective: The spleen is part of the lymphatic system and is one of the least understood organs of the human body. It is involved in the production of blood cells and helps filter the blood, remove old blood cells, and fight infection. Partial splenic artery embolization (PSE) is widely used to treat pancytopenia and portal hypertension.

Secondary immunoglobulin A nephropathy with gross hematuria leading to rapidly progressive glomerulonephritis following severe acute respiratory syndrome coronavirus 2 vaccination: a case report.

Background: The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been followed by many reports of the development and relapse of autoimmune diseases associated with SARS-CoV-2 vaccination. Some of these reports have involved relapse or onset of immunoglobulin A (IgA) nephropathy following SARS-CoV-2 vaccination. Here, we report on a patient with IgA nephropathy who presented with gross hematuria and rapidly progressive glomerulonephritis following SARS-CoV-2 vaccination.
