Population-Based Study on the Epidemiology of Ménière's Disease.

Background And Objective: Ménière's disease (MD) is a disorder of the inner ear typically showing recurrent acute episodes of vertigo, hearing loss, and tinnitus. Epidemiologic studies on MD are scarce. We assessed the incidence rates (IRs) of MD and describe the characteristics of MD cases, comparing them to control patients without recorded evidence of MD.

The association between thyroid disorders and incident gout: population-based case-control study.

Context: Thyroid hormones influence kidney function and thereby might alter serum urate levels, a major risk factor for gouty arthritis.

Objective: To assess the risk of developing incident gout in association with hypothyroidism or hyperthyroidism.

Design: Retrospective population-based case-control analysis.

Association of hormone therapy and incident gout: population-based case-control study.

Objective: This study aims to assess the odds of developing incident gout in association with the use of postmenopausal estrogen-progestogen therapy, according to type, timing, duration, and route of administration of estrogen-progestogen therapy.

Methods: We conducted a retrospective population-based case-control analysis using the United Kingdom-based Clinical Practice Research Datalink. We identified women (aged 45 y or older) who had a first-time diagnosis of gout recorded between 1990 and 2010.

Poorly controlled type 2 diabetes mellitus is associated with a decreased risk of incident gout: a population-based case-control study.

Objective: The aim of this study was to explore the risk of incident gout in patients with type 2 diabetes mellitus (T2DM) in association with diabetes duration, diabetes severity and antidiabetic drug treatment.

Methods: We conducted a case-control study in patients with T2DM using the UK-based Clinical Practice Research Datalink (CPRD). We identified case patients aged ≥18 years with an incident diagnosis of gout between 1990 and 2012.
