Background: Serum Procalcitonin (PCT) has been reported as a potential biomarker to predict the severity of acute cholangitis (AC) or the need for urgent biliary decompression. This study aimed to identify and summarize the existing research about the serum PCT and the severity of AC, and to find gaps where future studies can be targeted towards. Methods: Following the PRISMA Extension for Scoping Reviews, MEDLINE, EMBASE, and Google Scholar were searched for all peer-reviewed articles with rele...

There is insufficient evidence about the cardioprotective effects of statins against chemotherapy-induced cardiomyopathy. The MEDLINE and EMBASE databases were searched from inception to March 2021 for studies that reported the mean left ventricular ejection fraction (LVEF) before and after chemotherapy and the incidence of chemotherapy-induced cardiotoxicity in patients who received concurrent statin therapy and those who received chemotherapy alone. A random effects meta-analysis was performed...

A 75-year-old man with well-controlled type 2 diabetes was referred to our department because of urinary obstruction. He developed retroperitoneal fibrosis 1 year prior to the referral and underwent a ureteral stent insertion at that time. Around the same period, double vision and eyelid ptosis of the right eye coincidentally appeared (figure 1A). We performed MRI of the orbit; it revealed bilateral lacrimal enlargement, especially at the right side (figure 1B, C …

Differentiation between adult T-cell leukemia/lymphoma (ATLL) and peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), is often challenging based on pathological findings alone. Although serum anti-HTLV-1 antibody positivity is required for ATLL diagnosis, this information is often not available at the time of pathological diagnosis. Therefore, we examined whether the expression of SOX4 and p16 would be helpful for differentiating the two disease entities. We immunohistochemically exa...

Immunoglobulin G4-related disease (IgG4-RD) is a systemic disorder characterized by tissue fibrosis and intense lymphoplasmacytic infiltration, causing progressive organ dysfunction. Activation-induced cytidine deaminase (AID), a deaminase normally expressed in activated B-cells in germinal centers, edits ribonucleotides to induce somatic hypermutation and class switching of immunoglobulin. While AID expression is strictly controlled under physiological conditions, chronic inflammation has been ...

The coronavirus disease 2019 (COVID-19) global pandemic has drastically changed how we live and work. Amid the prolonged pandemic, burnout of the frontline healthcare professionals has become a significant concern. We conducted a cross-sectional survey study to provide data about the relationship between the COVID-19 pandemic and the prevalence of burnout in healthcare professionals in Japan. Healthcare workers in a single Japanese national university hospital participated in the survey, includi...

Objective The Mini-Z 2.0 is a new, simple, and nonproprietary tool for assessing physician well-being and burnout. To date, a non-English version of the Mini-Z 2.0 survey has not been validated. Therefore, we aimed to develop a Japanese version of the Mini-Z 2.0 and to evaluate its validity and reliability using survey data from physicians affiliated with an internal medicine academic society. Methods The Mini-Z 2.0 survey was translated into Japanese using a forward-backward translation method....

BACKGROUND: The COVID-19 pandemic has negatively affected medical education. However, little data are available about medical students' distress during the pandemic. OBJECTIVE: This study aimed to provide details on how medical students had been affected by the pandemic. METHODS: Cross-sectional study. 717 medical students participated in the web-based survey. The questions included how their mental status had changed before and after the Japanese nationwide state of emergency (SOE). RESULTS: 65...

Epstein-Barr virus (EBV)-positive mucocutaneous ulcer (EBVMCU) was first described as a lymphoproliferative disorder in 2010. EBVMCU is a unifocal mucosal or cutaneous ulcer that often occurs after local trauma in patients with immunosuppression; the patients generally have a good prognosis. It is histologically characterized by proliferating EBV-positive atypical B cells accompanied by ulcers. On the basis of conventional pathologic criteria, EBVMCU may be misdiagnosed as EBV-positive diffuse l...

Background: Histidine-rich glycoprotein (HRG) treatment ameliorated the survival rate of septic mice by suppressing excess immunothrombus formation. Although such findings suggested that HRG may be one of the most useful drugs for sepsis, obtaining a stable experimental system to standardize the HRG drug product is difficult to achieve using neutrophils isolated from volunteers. This is due to the short survival time and individual differences of human neutrophils. In the present study, we deter...
