Clinical analysis of gender and pre-existing diabetes mellitus in patients with polymyalgia rheumatica: A retrospective study in a Japanese population.

Objective: This study clarifies the involvement of gender and pre-existing diabetes mellitus (DM) in the clinical characteristics of polymyalgia rheumatica (PMR).

Methods: The clinical records of patients diagnosed with PMR in our department between January 2011 and June 2021, especially in terms of gender and DM were retrospectively analysed.

Results: We identified 89 patients with the median age of 75.

Subacute thyroiditis in a patient with psoriatic arthritis switched from secukinumab to adalimumab: a case report and literature review.

A 71-year-old Japanese female with psoriatic arthritis (PsA) was admitted for fever and neck pain. Her medication had been switched from secukinumab, an interleukin (IL)-17A inhibitor, to adalimumab, a tumour necrosis factor (TNF)-α inhibitor, due to secondary failure for PsA. She was diagnosed with subacute thyroiditis (SAT) on the basis of thyroid hormone levels and thyroid ultrasound findings.

Clinical and Genetic Characteristics of Non-Insulin-Requiring Glutamic Acid Decarboxylase (GAD) Autoantibody-Positive Diabetes: A Nationwide Survey in Japan.

Aims: Glutamic acid decarboxylase autoantibodies (GADAb) differentiate slowly progressive insulin-dependent (type 1) diabetes mellitus (SPIDDM) from phenotypic type 2 diabetes, but many GADAb-positive patients with diabetes do not progress to insulin-requiring diabetes. To characterize GADAb-positive patients with adult-onset diabetes who do not require insulin therapy for >5 years (NIR-SPIDDM), we conducted a nationwide cross-sectional survey in Japan.

Methods: We collected 82 GADAb-positive patients who did not require insulin therapy for >5 years (NIR-SPIDDM) and compared them with 63 patients with insulin-requiring SPIDDM (IR-SPIDDM).

Sequential elevation of autoantibodies to thyroglobulin and glutamic acid decarboxylase in type 1 diabetes.

We have previously reported the high levels of glutamic acid decarboxylase 65 autoantibodies (GAD65A) in patients with type 1 diabetes and autoimmune thyroid disease. Here we describe a 32-year-old Japanese female with a thirteen-year history of type 1 diabetes whose levels of GAD65A were elevated just after the emergence of anti-thyroid autoimmunity. At 19 years of age, she developed diabetic ketoacidosis and was diagnosed with type 1 diabetes.

Putative IgG4-related pituitary disease with hypopituitarism and/or diabetes insipidus accompanied with elevated serum levels of IgG4.

IgG4-positive plasma cell infiltration into multiple organs or tissues, such as the pancreas and salivary glands, associated with increased serum levels of IgG4 is a characteristic finding seen in IgG4-related disease. Affected organs may appear tumorous as a result of chronic inflammatory processes accompanied with progressive fibrosis. Recent cases of this disorder in which the pituitary gland was affected include cases of diffuse enlargement of the pituitary and/or its stalk associated with central diabetes insipidus and/or impaired anterior hormone production.

Electrochemical deposition of gold frame structure on silver nanocubes.

Au-framed Ag nanocubes were prepared by site-selective electrochemical deposition of Au onto the edges and vertices of Ag nanocubes modified with a self-assembled monolayer (SAM) of 1-octanethiol, and further chemical etching of the Ag cubes used as a template produced Au nanoframes.

Dorsal Column Degeneration after Bortezomib Therapy in a Patient with Multiple Myeloma.

We present here a case of dorsal column degeneration in a female patient with multiple myeloma following exposure to bortezomib. Two days after intravenous administration of a first course of bortezomib 1 mg/m(2), the patient developed rapidly-progressive numbness, pain and muscle weakness in the bilateral upper and lower limbs. Following gancyclovir treatment of subsequent cytomegalovirus viremia, the patient went on to receive a course of EPOCH (etoposide 50 mg/m(2)/day on days 1-4, vincristine 0.

Non-specific activities against ruthenium crosslinker as a new cause of assay interference in an electrochemilluminescent immunoassay.

Clinical assays are very important for the diagnosis and management of clinical disorders. Each assay system consists of a specific method to detect and/or quantify a substance of interest in the clinical specimen. However, clinical assays can be unfavorably influenced by non-specific activities concomitantly present in the specimen, which may mislead clinical decisions.
