Survey of diversity awareness and environment among members of the Pediatric Rheumatology Association of Japan.

Background: Diversity management has gained traction in Japan. The Pediatric Rheumatology Association of Japan (PRAJ) has an Advisory Committee for Diversity Promotion with a broader focus on promoting diversity. The objectives of this study were to better understand the problems faced by PRAJ members regarding the work environment, childcare and nursing care, and work-life balance.

Subcutaneous Panniculitis-like T-cell Lymphoma with a HAVCR2 Mutation Diagnosed after 10 Years of Treatment with Glucocorticoids and Cyclosporine as Lupus Panniculitis.

Subcutaneous panniculitis-like T cell lymphoma (SPTCL) is a very rare cutaneous T cell lymphoma that has been reported to be associated with autoimmune disorders but is most commonly associated with systemic lupus erythematosus. We herein report a 26-year-old man thought to have lupus panniculitis (LP) treated for 10 years with corticosteroids and cyclosporine. After several relapses with panniculitis, he was finally diagnosed with SPTCL, which was confirmed to have a HAVCR2 mutation for p.

Different pharmacoresistance of focal epileptic spasms, generalized epileptic spasms, and generalized epileptic spasms combined with focal seizures.

Objective: Among standard treatments for infantile spasms, adrenocorticotropic hormone (ACTH) is reported as the best treatment, but ACTH is ineffective in one-half of the patients. To establish precision medicine, we examined pharmacoresistance of focal epileptic spasms (ES), generalized ES, and generalized ES combined with focal seizures, diagnosed based on the revised seizure classification of ILAE in 2017.

Methods: We conducted a retrospective nationwide study in Japan on the long-term seizure outcome of ES.

Safety and response to influenza vaccine in patients with systemic-onset juvenile idiopathic arthritis receiving tocilizumab.

Objective: We investigated the safety and efficacy of administering influenza vaccines to patients with systemic-onset juvenile idiopathic arthritis (sJIA) treated with tocilizumab.

Patients And Methods: The subjects were 27 sJIA patients treated with tocilizumab and 17 healthy age- and sex-matched volunteers. Serum samples were collected prior to and 4-7 weeks after vaccination.

[Infliximab therapy for three adolescent patients with refractory Takayasu's arteritis].

Takayasu's arteritis (TA) is a chronic idiopathic inflammatory disease affecting primarily aorta and its proximal branches. Pediatric patients with TA tend to have more severe clinical course and be refractory to conventional treatments compared with adults. Corticosteroids are major treatment of TA, however, high dose is required to get remission.

[Two patients with childhood-onset Behcet's disease successfully treated by anti-tumor necrosis factor therapy].

Behçet's disease (BD) is a multisystem immune-mediated inflammatory disorder. The choice of treatments depends on organ involvements and its severity. The treatments for pediatric patients usually consist of corticosteroids and immunosuppressants, but some of them are refractory to these treatments.

Effect of anakinra on arthropathy in CINCA/NOMID syndrome.

CINCA/NOMID is an autoinflammatory disorder characterized by the triad of neonatal onset of cutaneous symptoms, chronic meningitis, and recurrent fever and it presents with distinctive osteoarthropathy, synovitis mainly of the large joints and overgrowth of epimetaphyseal cartilage, particularly of the long bones. The cartilage overgrowth eventually causes osseous overgrowth and deformity that persists beyond skeletal maturity and leads to limb length discrepancy, joint contracture, and early degenerative arthropathy. Autoinflammation in CAPS/NOMID has been proven to derive from excessive release of interleukin-1 (IL-1).

[Clinical and histological experience of labial lip biopsy in juvenile Sjögren syndrome].

The therapeutic efficacy of corticosteroids and immunosuppressants on secretary glands of children with Sjögren syndrome was investigated examining the lip-biopsy specimen on both lymphocyte infiltration and fibrosis. Six children with primary Sjögren syndrome and two children with lupus-associated secondary Sjögren syndrome were evaluated according to the intensity of therapy. The shorter the term of medications of corticosteroids and immunosuppressants were, the lesser the extents of lymphocyte infiltration and fibrosis were, and the lower the doses of medications were, the lesser the efficacy was.
