Successful management of a case of intestinal Behçet's disease with a splenic abscess by intensified immunosuppressive therapy without splenectomy.

Behçet's disease (BD) is often associated with neutrophilic dermatosis. However, BD is rarely associated with aseptic abscesses in the spleen or liver. A 2-year-old girl presented to our hospital with a 2-week history of fever, abdominal pain, and a skin ulcer on her leg.

In-Depth Serum Proteomics by DIA-MS with Spectral Libraries Reveals Dynamics during the Active Phase of Systemic Juvenile Idiopathic Arthritis.

In serum proteomics using mass spectrometry, the number of detectable proteins is reduced due to high-abundance proteins, such as albumin. However, recently developed data-independent acquisition mass spectrometry (DIA-MS) proteomics technology has made it possible to remarkably improve the number of proteins in a serum analysis by removing high-abundance proteins. Using this technology, we analyzed sera from patients with systemic juvenile idiopathic arthritis (sJIA), a rare pediatric disease.

A three-generation Muckle-Wells syndrome family: Detailed family history, physical examination, and inter-departmental collaboration.

Cryopyrin-associated periodic syndrome (CAPS) is a rare inherited autoinflammatory disease caused by gain-of-function mutations in the NLRP3 gene, with a genotype-phenotype correlation. The clinical presentation of each mutation has been previously studied. However, very few studies have reported on the clinical characteristics and treatment effectiveness across different generations within a family with the same mutation.

The influence of tonsillectomy on allergic diseases in pediatric patients.

Background: The influence of tonsillectomy on allergic airway diseases is not well known.

Objectives: In the present study, the influence of tonsillectomy on perennial allergic rhinitis (PAR) and bronchial asthma (BA) among pediatric subjects was prospectively investigated.

Methods: The tonsillectomy (surgery group) and the age-matched non-surgical subjects (control group) were examined and followed prospectively.

Early use of alendronate as a protective factor against the development of glucocorticoid-induced bone loss in childhood-onset rheumatic diseases: a cross-sectional study.

Background: Bisphosphonates are recommended for use as first-line therapy for the prevention and treatment of glucocorticoid-induced osteoporosis in adults. However, the appropriate usage of bisphosphonates for the prevention or treatment of glucocorticoid-induced osteoporosis in children remains unclear.

Methods: We performed a cross-sectional study to clarify the factors associated with the development of glucocorticoid-induced bone loss and osteoporosis in patients with childhood-onset rheumatic disease and to investigate the impact of the early use of alendronate.
