We experienced two cases of hepatitis C virus (HCV) eradication failure in patients with a history of non-responsiveness to previous treatments with direct-acting antiviral agents (DAAs) who were subsequently treated with the combination of glecaprevir and pibrentasvir (GLE/PIB). Direct sequencing at commencement of GLE/PIB therapy showed non-structural protein (NS) 5A-P32 deletion in the first patient and NS5A-R30E/Q54H/A92K in the second patient (both genotype 1b). ⋯ Even when L31/Y93 is double wild-type, other NS5A mutations may affect the DAA re-treatment outcome. We analyzed the transition of amino acid mutations at NS5A by ultra-deep sequencing.

Case Reports
An Anti-PM/Scl-75 Antibody-positive Japanese Woman Who Developed Inflammatory Myopathy.
A 69-year-old Japanese woman presented with mild muscle weakness of the neck and symmetrical proximal parts of the upper and lower limbs. Laboratory tests, needle electromyography, and a muscle biopsy revealed inflammatory myopathy with an apparent clinical classification of polymyositis and positive findings for anti-PM/Scl-75 antibody. ⋯ The muscle biopsy also showed marked necrotic and regenerative fibers. We need to collectively investigate patients with the potential to develop this disease, and to identify any unique characteristics for Asian populations, including Japanese.

Review Case Reports
Accidental Hypothermia Treated by Hemodialysis in the Acute Phase: Three Case Reports and a Review of the Literature.
Accidental hypothermia is defined as a core body temperature <35°C. Even with the use of multiple active rewarming methods, it has a high mortality rate. ⋯ We herein report three patients with severe or moderate accidental hypothermia who were treated by hemodialysis in the acute phase. This case report with a literature review describes the usefulness of hemodialysis for the treatment of moderate and severe accidental hypothermia without cardiac arrest.

A 24-year-old Japanese man exhibited slowly progressive gait disturbance from childhood to young adulthood. Physical and physiological examinations showed the involvement of both upper and lower motor neurons, fulfilling the diagnostic criteria for amyotrophic lateral sclerosis (ALS). Mild cognitive impairment and subclinical sensory involvement were also observed. ⋯ Asp267Gly), in the vaccinia-related kinase 1 gene (VRK1). This is the first report of a Japanese patient with a motor neuron disease phenotype caused by VRK1 mutations. This diagnosis should be considered in atypical cases of juvenile-onset and slowly progressive types of motor neuron disease.

Objective This follow-up survey report describes medication adherence and patient preferences, beliefs, and expectations of maintenance hemodialysis treatment in Japan. Methods This patient-reported questionnaire-based survey was conducted in six regions in Japan from September 2016 to November 2016. Patients The questionnaire was provided to 700 patients (50-79 years old) on maintenance hemodialysis for >3 years who were members of the Japan Association of Kidney Disease Patients. ⋯ In addition, 37.8% (198/524) of patients responded that the elimination of 1 medication (1 tablet) would reduce their mental burden. Conclusion The results of this survey show that overall medication adherence is high in Japanese patients on maintenance hemodialysis. While many patients perceive an absence of mental burden, they still prefer to avoid oral medication when possible.
