High prevalence of anti-TSH receptor antibody in fibromyalgia syndrome.

Aim: Fibromyalgia syndrome (FMS) is defined as chronic widespread pain that cannot be accounted for by any other medical disorder. Our aim was to explore the prevalence of thyroid autoimmunity in patients with FMS.

Methods: For determining thyroid function in 207 FMS patients, we tested for the titers of free tri-iodothyronine, free thyroxine, thyroid-stimulating hormone (TSH), anti-thyroid peroxidase antibody (TPOAb), anti-thyroglobulin antibody (TgAb) and anti-TSH receptor antibody (TRAb).

Murine hypothalamic destruction with vascular cell apoptosis subsequent to combined administration of human papilloma virus vaccine and pertussis toxin.

Vaccination is the most powerful way to prevent human beings from contracting infectious diseases including viruses. In the case of the human papillomavirus (HPV) vaccine, an unexpectedly novel disease entity, HPV vaccination associated neuro-immunopathetic syndrome (HANS), has been reported and remains to be carefully verified. To elucidate the mechanism of HANS, we applied a strategy similar to the active experimental autoimmune encephalitis (EAE) model - one of the most popular animal models used to induce maximum immunological change in the central nervous system.

Psychometric assessment of the Japanese version of the Revised Fibromyalgia Impact Questionnaire: reliability and validity.

Aim: To assess the psychometric properties of the Japanese version of the Revised Fibromyalgia Impact Questionnaire (JFIQR) in fibromyalgia (FM) patients.

Method: The reliability and validity of the JFIQR were assessed using online data collected from Japanese FM patients. Reliability was evaluated based on test-retest reliability results and internal consistency; validity was evaluated on the basis of concurrent and known-group validity.

An epidemiologic internet survey of fibromyalgia and chronic pain in Japan.

Objective: To determine the epidemiologic features and symptom characteristics of fibromyalgia (FM) in Japan, and compare them with those for other chronic pain (CP) diagnoses.

Methods: An internet survey was conducted in June and July 2011. The questionnaire consisted of 111 questions, including assessments of the Japanese version of the 2010 American College of Rheumatology preliminary diagnostic criteria for FM, the Japanese Fibromyalgia Impact Questionnaire, and additional questions regarding pain and lifestyle.

Development of the Japanese version of the Fibromyalgia Impact Questionnaire (JFIQ): psychometric assessments of reliability and validity.

Aim: To perform a psychometric assessment of the Japanese version of the Fibromyalgia Impact Questionnaire (JFIQ).

Methods: Data for the psychometric assessment were collected from Japanese fibromyalgia (FM) patients who visited a clinic. Analyses were performed to examine the reliability and validity of the JFIQ.
