Blood DNA virome associates with autoimmune diseases and COVID-19.

Aberrant immune responses to viral pathogens contribute to pathogenesis, but our understanding of pathological immune responses caused by viruses within the human virome, especially at a population scale, remains limited. We analyzed whole-genome sequencing datasets of 6,321 Japanese individuals, including patients with autoimmune diseases (psoriasis vulgaris, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), pulmonary alveolar proteinosis (PAP) or multiple sclerosis) and coronavirus disease 2019 (COVID-19), or healthy controls. We systematically quantified two constituents of the blood DNA virome, endogenous HHV-6 (eHHV-6) and anellovirus.

Large Spontaneous Subcutaneous Abscess Formation due to in a Diabetic Patient: A Case Report.

Introduction: is a member of the Gram-positive anaerobic cocci group and constitutes the flora of the skin and other parts of the body. It sometimes colonizes diabetic foot and rarely infects skin or soft tissue of non-immunocompromised patients.

Case Presentation: Here, we report the case of a severe subcutaneous abscess on the back caused by .

Clinical course of psoriatic arthritis treated with biologics delineated with ultrasonography.

Psoriatic arthritis (PsA) is a chronic, inflammatory articular disease regarded as a specific subtype of psoriasis. Long-term assessment for PsA using ultrasonography has not yet been investigated. The present study was conducted to delineate the changes in articular lesions after the initiation of biologics using ultrasonography, and to provide the evidence of the utility of ultrasonography in long-term follow-up of PsA patients.

Region-specific activation in the accumbens nucleus by itch with modified scratch efficacy in mice - a model-free multivariate analysis.

Itch is a protective/defensive function with divalent motivational drives. Itch itself elicits an unpleasant experience, which triggers the urge to scratch, relieving the itchiness. Still, it can also result in dissatisfaction when the scratch is too intense and painful or unsatisfactory due to insufficient scratch effect.

Real-world Settings for the Surgical Treatment of Neurofibroma in Patients with Neurofibromatosis Type 1.

Introduction: Even though an MEK inhibitor has been recently launched, neurofibroma still negatively affects the well-being of patients with neurofibromatosis type 1 (NF1). The coronavirus disease 2019 (COVID-19) pandemic resulted in restricted access to medical care. The present study was conducted to investigate the real-world settings of patients with NF1 who underwent surgery with or without restricted medical access during the COVID-19 pandemic.

A case of leukemia cutis showing annular erythema during the course of Philadelphia chromosome-positive acute B-lymphoblastic leukemia.

We report a case of leukemia cutis showing annular erythema during the course of Philadelphia chromosome-positive acute B-lymphoblastic leukemia. The annular appearance may be developed by immunomodulatory effects of blinatumomab.

A case of varicella due to primary varicella zoster virus infection followed by respiratory disease on the background of an immunocompromised condition.

We encountered an immunocompromised patient with severe respiratory disease immediately after the onset of varicella. Varicella zoster virus infection may be associated with more severe immunosuppressive condition.

A cross-sectional questionnaire survey involving physicians for the clarification of the diagnosis and current status of therapeutic intervention of psoriatic arthritis in Japan.

Patients with psoriatic arthritis (PsA) often experience comorbid, irreversible joint destruction, therefore early diagnosis and treatment of PsA are important. The diagnosis requires a comprehensive assessment, which includes an interview, a physical examination, a visual examination of the skin and nails, a blood test, and an imaging test. To clarify how patients with PsA are actually diagnosed and how physicians collaborate among clinical departments, we conducted a web-based questionnaire survey of 500 physicians (dermatologists, rheumatologists, and orthopedists) frequently involved in PsA treatment in Japan.

Real-world Evidence for the Treatment of Rosacea with Sulfur or Metronidazole Preparation in Japanese Patients.

Introduction: There remains to be lacking real-world evidence for the treatment of rosacea with a topical sulfur preparation (TSP) or topical metronidazole preparation (TMP) among Japanese patients. Therefore, in this study, we examined the effects of TSP and TMP on rosacea in Japanese patients in real-world clinical settings.

Methods: This retrospective observational analysis reviewed the medical records of 47 Japanese patients who were treated with TSP or TMP for more than 8 weeks in our clinic.

Monitoring Sleep and Scratch Improves Quality of Life in Patients with Atopic Dermatitis.

Atopic dermatitis itch may cause sleep disturbance and impair quality of life. For patients finding topical therapy difficult to continue, it is important to control itch and reduce scratching. This study developed algorithms to measure nocturnal sleep and scratch, using an actigraph device worn on the back of the hand, and assessed smartphone application feedback to improve adherence with therapy.

Characteristics of mild and severe apalutamide-related cutaneous adverse events in patients with prostate cancer: A review of the literature.

Apalutamide is an antiandrogen used to treat prostate cancer. Although it sometimes induces mild cutaneous adverse events and occasionally severe ones, clinical differences between severe and mild cases remain unclear. To assess the risks in patients experiencing apalutamide-related cutaneous adverse events (ARCAEs), we aimed to characterize severe and mild ARCAEs in terms of onset time and lymphocyte transformation test (LTT) for apalutamide.
