Frailty Status Predicts New Long-term Care Insurance Certification in Hepatitis C Patients Receiving Antiviral Therapy.

Background/aim: Direct-acting antiviral (DAA) therapies for patients with hepatitis C virus (HCV) infection deliver higher cure rates and lower frequencies of adverse events than existing therapies, though DAA treatment costs $45,000-64,000 in Japan. The prognosis of patients who require new long-term care insurance (LTCI) certification is inferior to that of patients who do not. Here, we clarify the factors associated with new LTCI certification in elderly patients with HCV infection who undergo DAA therapy.

Pathogenesis of taste impairment and salivary dysfunction in COVID-19 patients.

Coronavirus disease 2019 (COVID-19) is a highly transmissible pandemic disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The characteristics of the disease include a broad range of symptoms from mild to serious to death, with mild pneumonia to acute respiratory distress syndrome and complications in extrapulmonary organs. Taste impairment and salivary dysfunction are common early symptoms in COVID-19 patients.

Acute Liver Failure Due to Severe Hepatic Metastasis of Small-cell Lung Cancer Producing Adrenocorticotropic Hormone Complicating Ectopic Cushing Syndrome.

A 72-year-old man was admitted to a general hospital with progressive liver dysfunction, hypokalemia, hyperglycemia, and nodules in the lung and liver and then transferred to our institution on the seventh hospital day. Plasma levels of adrenocorticotropic hormone (ACTH), cortisol, and neuron-specific enolase concentrations were extremely high. He developed acute liver failure, his consciousness and general condition deteriorated rapidly, and he died on Day 11.

Monocyte-derived fibrocytes elimination had little contribution on liver fibrosis.

Background: Monocyte-derived fibrocytes play an important role in the progression of fibrosis in the skin, lungs, heart and kidney. However, the contribution of fibrocytes to liver fibrosis is unclear. The aim of this study was to investigate whether fibrocytes contributed to fibrosis progression in the livers of carbon tetrachloride (CCl)-treated mice.

Symposium: Imaging modalities for drug-related osteonecrosis of the jaw (1), role of imaging in drug-related osteonecrosis of the jaw: An up-to-date review (secondary publication).

MRONJ/ARONJ is a serious adverse effect of medication, although the incidence of the disease is rare, and there are still controversial issues regarding the pathogenesis of MRONJ/ARONJ. Medications that can lead to MRONJ/ARONJ are commonly used to treat osteoporosis and to prevent bone fractures caused by bone metastasis of malignancies. The long-standing disease state of ONJ deteriorates the quality of life of affected patients.
