A cross-sectional study of anterior cutaneous nerve entrapment syndrome at a Japanese emergency department.

Background: Anterior cutaneous nerve entrapment syndrome (ACNES) is the most common cause of abdominal wall pain. This study aimed to clarify the proportion of ACNES cases among those of abdominal pain and the clinical characteristics and prognosis of the disease in an emergency department (ED) of a Japanese general hospital.

Methods: The medical records of patients from January 2014 to December 2023 were reviewed, and patients aged 15 years or older with abdominal pain with positivity for Carnett's sign, a good response to trigger point injection (TPI), and an ACNES diagnosis were included.

Spontaneous spinal epidural hematoma with hemiparesis: A stroke mimic.

Spontaneous spinal epidural hematoma (SSEH) is a rare cause of neck pain and hemiparesis. Clinicians should keep SSEH in mind as a rare stroke mimic presenting with hemiparesis to avoid needless and potentially hazardous thrombolytic therapy. Taking a careful history is useful for making a correct diagnosis.

Pseudo-mediastinal tumor: Brachiocephalic artery buckling.

Buckling of the brachiocephalic artery is an important cause of unusual chest x-ray findings which resemble those of a mediastinal tumor. The possibility of a vascular anomaly should be kept in mind whenever a chest x-ray demonstrates an abnormal mediastinal opacity, especially in elderly female patients with hypertension.

C-reactive protein and the neutrophil-to-lymphocyte ratio on admission predicting bacteraemia with COVID-19.

Background: Bacteraemia can co-occur with COVID-19. The present study aimed to determine the cut-off value for C-reactive protein (CRP) and the neutrophil-to-lymphocyte ratio (NLR) for predicting bacteraemia in patients with COVID-19.

Methods: Patients admitted to Tokyo Metropolitan Tama Medical Centre for COVID-19 treatment between 1 April 2020 and 30 October 2022 were included.

Bochdalek Hernia Causing Sigmoid Colon Strangulation in an Elderly Patient.

Diaphragmatic hernia with bowel strangulation is a fatal condition requiring a prompt diagnosis. Bochdalek hernia is a common type of diaphragmatic hernia that rarely but occasionally occurs in adults. We herein report a case of Bochdalek hernia causing sigmoid colon strangulation in an elderly patient whose condition was initially misdiagnosed as empyema.

Pleural effusion as a rare presentation of foreign body aspiration.

Unsuspected, non-asphyxiating, aspirated foreign body often masquerades as unresolved pneumonia, bronchiolitis or bronchial asthma. We report herein an 82-year-old, male patient with pleural effusion. Although the patient received the diagnosis of heart failure and treatment with diuretics, the pleural effusion remained, and a productive cough and a low-grade fever developed.

Promoting coronavirus disease 2019 (COVID-19) vaccination among healthcare personnel: A multifaceted intervention at a tertiary-care center in Japan.

Objective: The coronavirus disease 2019 (COVID-19) vaccine may hold the key to ending the pandemic, but vaccine hesitancy is hindering the vaccination of healthcare personnel (HCP). We examined their perceptions of the COVID-19 vaccine and implemented an intervention to increase vaccination uptake.

Design: Before-and-after trial.

Diagnosing Pollen-food Allergy Syndrome Allergologically in a Patient with Suspected Eosinophilic Gastroenteritis.

Pollen-food allergy syndrome (PFAS) consists of type I allergy to pollen and multiple food items that are cross-reactive to the pollen. PFAS typically occurs in the oral cavity and can co-occur with eosinophilic esophagitis. However, it is infrequently reported to present with symptoms of eosinophilic gastroenteritis (EGE), such as abdominal pain and eosinophilic infiltration of the gastrointestinal tract.

Risk factors for post-bronchoscopy pneumonia: a case-control study.

The bronchoscopy, though usually safe, is occasionally associated with complications, such as pneumonia. However, the use of prophylactic antibiotics is not recommended by the guidelines of the British Thoracic Society. Thus far there are few reports of the risk factors for post-bronchoscopy pneumonia; the purpose of this study was to evaluate these risk factors.

Evaluation of a novel urinary antigen test kit for diagnosing Legionella pneumonia.

Objectives: The aim of this study was to evaluate the diagnostic utility of a novel test kit that could theoretically detect all serogroups of Legionella pneumophila for diagnosing Legionella pneumonia, in comparison with existing kits.

Methods: This study was conducted in 16 hospitals in Japan from April 2016 to December 2018. Three urinary antigen test kits were used: the novel kit (LAC-116), BinaxNOW Legionella (Binax), and Q-line Kyokutou Legionella (Q-line).

Ultrasensitive enzyme-linked immunosorbent assay for the detection of MPT64 secretory antigen to evaluate Mycobacterium tuberculosis viability in sputum.

Objectives: This study examined Mycobacterium tuberculosis (MTB)-secreted MPT64 as a surrogate of bacterial viability for the diagnosis of active pulmonary TB (PTB) and for follow-up treatment.

Methods: In this proof-of-concept prospective study, 50 PTB patients in the Tokyo metropolitan region, between 2017 and 2018, were consecutively included and 30 healthy individuals were also included. Each PTB patient submitted sputum on days 0, 14 and 28 for diagnosis and follow-up, and each healthy individual submitted one sputum sample.

[Efficacy and Safety of Gefitinib as First-Line Chemotherapy for Elderly Patients with Advanced Non-Small Cell Lung Cancer(NSCLC)].

Epidermalgrowth factor receptor tyrosine kinase inhibitor(EGFR-TKI)is the first choice for the treatment of EGFR mutation- positive advanced non-small cell lung cancer(NSCLC). There have been few reports on the efficacy and safety of gefitinib in elderly patients with EGFR mutation-positive advanced NSCLC. We retrospectively assessed the efficacy and safety of gefitinib as first-line chemotherapy in 22 patients with advanced NSCLC aged 75 years or older and who were treated with gefitinib.

A Case Series of Acute Kidney Injury During Anti-tuberculosis Treatment.

Objective The standard anti-tuberculosis (TB) regimen occasionally causes acute kidney injury (AKI). The major etiology is rifampicin-induced acute interstitial nephritis. However, the standard management of AKI induced by anti-TB drugs has yet to be established.

Development of a microwave-assisted sustainable conversion of furfural hydrazones to functionalised phthalimides in ionic liquids.

A sustainable synthetic procedure to convert furfural hydrazones into functionalised phthalimides was developed. The reaction was performed in a microwave using a hydrophilic ionic liquid, [bmim][Cl], as the solvent which could be readily recovered by a simple extraction. The ionic liquid was successfully recycled with no significant loss in product yields.

TAFRO syndrome: current perspectives.

Multicentric Castleman's disease (MCD), a distinct subtype of Castleman's disease, is a rare, nonneoplastic, lymphoproliferative disorder. Patients with MCD present with systemic symptoms and multiple lymphadenopathy. Lymph node biopsy is necessary for the diagnosis of various histological MCD patterns including hyaline vascular, plasma cell, and mixed types.

An anterior mediastinal lesion in TAFRO syndrome showing complete remission after glucocorticoid and tocilizumab therapy.

Thrombocytopenia (T), anasarca (A), myelofibrosis (F), renal dysfunction (R), and organomegaly (O) (TAFRO) syndrome is a variant of multicentric Castleman's disease. We describe here a 57-year-old man who presented with persistent fever, pleural effusion, and ascites. He was negative for human immunodeficiency virus and human herpes virus-8.

Saddle nose with sarcoidosis: "A great imitator" of relapsing polychondritis.

Sarcoidosis is a systemic granulomatous disease that can affect any organ including the nose. Nasal crusting and congestion are common nasal symptoms of sarcoidosis, whereas cases of saddle-nose deformity are rarely reported. We describe here a case of sarcoidosis that presented with saddle nose resembling relapsing polychondritis.

[A CASE OF SPINAL TUBERCULOSIS WITH NEUROPATHY AMELIORATED BY DRAINING A TUBERCULOUS ILIOPSOAS ABSCESS WITHOUT SPINAL SURGERY].

A 75-year-old woman was referred to our hospital after a health check-up disclosed abnormal shadows in the bilateral lungs. The patient was admitted to our hospital after being diagnosed with pulmonary tuberculosis. A physical examination showed a mass in the left inguinal area.
