Anti-EJ antibody-positive interstitial pneumonia with breast cancer improved by combining immunosuppressive therapy and chemotherapy.

We present a case of a 45-year-old woman diagnosed with interstitial pneumonia (IP) during a comprehensive breast cancer evaluation. Although the patient showed no obvious clinical symptoms of polymyositis or dermatomyositis, the presence of anti-glycyl-transfer ribonucleic acid synthetase antibodies confirmed anti-synthetase syndrome. The patient began methylprednisolone for treatment of the IP.

Acute myeloid leukemia and myelodysplastic syndrome associated with a combination of immune checkpoint inhibitor and platinum-based chemotherapy.

Therapy related-acute myeloid leukemia (t-AML) and myelodysplastic syndrome (t-MDS) are complications of chemotherapy and/or radiation therapy for malignant diseases. In this report, we describe a patient with advanced lung adenocarcinoma who developed autoimmune hemolytic anemia and MDS associated with a combination of atezolizumab and platinum-based chemotherapy. The patient showed progression from t-MDS to t-AML 20 months after the treatment was initiated.

Resection of tracheal mucosa-associated lymphoid tissue (MALT) lymphoma by bronchoscopic high-frequency electrosurgical snare: Case report.

There is no standard method of bronchoscopic local therapy for tracheal tumours. We herein present a case involving a 61-year-old woman who was diagnosed with tracheal mucosa-associated lymphoid tissue lymphoma and underwent resection by a bronchoscopic high-frequency electrosurgical snare. Few reports to date have described such use of high-frequency electrosurgical snares; however, they are effective for the treatment of tracheal tumours, especially pedunculated tumours.

Estimated Gestational Age From Infant's Foot Length in Japanese.

Aim In developed countries including Japan, gestational age (GA) is predicted by the last menstrual period (LMP) and/or fetal ultrasound. In some developing countries, GA is predicted by infant's foot length (FL). Pregnant women who did not have pregnancy check-up is not infrequent in Japan, therefore there are sometimes opportunities to estimate the GA from infants after the delivery.

Laryngotracheal separation surgery in a patient with severe Angelman syndrome involving a 19.3 Mb deletion on 15q11.2-q14.

A severe Angelman syndrome (AS) patient with a very large deletion (19.3 Mb) at 15q11.2-q14 required laryngotracheal separation, which is not a common surgery in AS.

Advanced atypical lung carcinoid tumour successfully treated with carboplatin, etoposide and atezolizumab: A case report.

Atypical carcinoid tumours are relatively rare among lung cancers. Surgery is regarded as standard treatment for localized cases, but there is little established evidence on treatment strategies for advanced cases. Moreover, the efficacy of immune checkpoint inhibitors for advanced carcinoid tumours is unclear.

Recurrent Massive Hemothorax of Unknown Etiology in an 85-Year-Old Man.

An 85-year-old Japanese man, who was taking aspirin and edoxaban for previous myocardial infarction and atrial fibrillation, came to our hospital with a chief complaint of dyspnea for 3 weeks. Chest radiography showed a massive left pleural effusion (Fig 1A). Analysis of pleural fluid showed an elevated hematocrit level at 32.

Caffeine Intoxication Due to Antipyretic Analgesic Overdose in an Adolescent.

Recently, high concentrations of caffeine present in energy drinks and over-the-counter (OTC) drugs have become a concern worldwide. Several deaths due to caffeine intoxication have been reported, necessitating caution. Typically, supportive care is used to treat caffeine intoxication.

A Rare Case of Pulmonary Tumor Thrombotic Microangiopathy Associated with Micropapillary Urothelial Carcinoma of the Urinary Bladder: An Autopsy Case.

A 70-year-old woman was hospitalized with dyspnea. A transthoracic echocardiogram indicated an elevated systolic pulmonary artery pressure, and the cytology specimens obtained using a pulmonary artery catheter confirmed adenocarcinoma metastasis. Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) detected high-signal-intensity lesions in the urinary bladder.

A case of allergic bronchopulmonary aspergillosis with marked peripheral blood eosinophilia successfully treated with benralizumab.

We herein report a case of allergic bronchopulmonary aspergillosis (ABPA) with marked eosinophilia and high attenuation mucus (HAM) on chest computed tomography (CT), which demonstrated a rapid and remarkable improvement with benralizumab treatment. A 67-year-old Japanese woman, who was diagnosed with asthma at the age of 64 years, was admitted with dyspnea. Her blood test results showed marked eosinophilia (peripheral blood eosinophil count 24403/μL) and elevated serum IgE levels.

Tumor Embolism as a Cause of Renal Artery Occlusion and Acute Kidney Injury Diagnosed and Treated with Endovascular Intervention in a Patient with Mediastinal Undifferentiated Sarcoma.

A 72-year-old man presented with back pain due to a mass in the left posterior mediastinum that had surrounded and partly infiltrated the descending aorta. Mediastinal undifferentiated sarcoma was diagnosed. After the diagnosis, sudden anuria was observed.

Infection Complicated with Bacteremia in a 10-Month-Old Boy.

() infection complicated with bacteremia rarely occurs. infection is also known to produce various symptoms similar to Kawasaki disease (KD) due to the production of -derived mitogen (YPM), an exotoxin with superantigen activity. Moreover, it causes terminal ileitis and is responsible for appendix swelling.

Characteristics of socially high-risk pregnant women and children's outcomes.

Background: The number of reports of child abuse and neglect in Japan has increased each year. A causal relationship between socially high-risk pregnant women and child abuse is strongly suggested. This study aims to investigate the characteristics of socially high-risk pregnant women and their children's outcomes, to help prevent child abuse.

Extended-stay hospitalization for childhood asthma in Japan.

Background: While recent advances in asthma management have enabled adequate control to be frequently achieved in outpatient settings, children whose asthma remains poorly controlled despite outpatient treatment are often referred to extended-stay hospitals. The aim of the present study was to examine trends concerning extended-stay hospitalization and to evaluate the present status of this approach.

Methods: A retrospective study was conducted to assess changes in the number of admissions among 408 children with extended stays at Kamiamakusa General Hospital between 1989 and 2005.

Ghrelin and leptin modulate immunity and liver function in overweight children.

Background: The rising prevalence of obesity represents a growing worldwide public health problem. Interactions of adipocytokines and low-grade systemic inflammation presently are considered important in the development of obesity, as well as associated chronic disease including bronchial asthma, obesity-related liver disease and type 2 diabetes mellitus. The purpose of the present study was to investigate metabolic, hormonal, immunologic and inflammatory factors in overweight children and to further clarify possible immunomodulatory effects of obesity-related hormones and cytokines.
