OBJECTIVE To report two patients with giant cell arteritis (GCA) who developed rheumatoid arthritis (RA) and to review the literature in terms of coexistence of RA, GCA, and polymyalgia rheumatica (PMR). METHODS We conducted a comprehensive review of the English literature from 1980 to 2015 to analyze data on the coexistence of GCA and RA. The PubMed, Web of Science, Proquest, and Ovid databa...

BACKGROUND Giant cell arteritis (GCA), if untreated, can lead to blindness and stroke. The study's objectives were to (1) determine a new evidence-based benchmark of the extent of diagnostic delay for GCA and (2) examine the role of GCA-specific characteristics on diagnostic delay. METHODS Medical literature databases were searched from inception to November 2015. Articles were included if re...

The use of 18F-fluoro-deoxyglucose positron emission tomography scan (FDG-PET) and computed tomography angiography (CTA) to improve accuracy of diagnosis of giant cell arteritis (GCA) is a very important clinical need. We aimed to compare the diagnostic performance of FDG-PET and CTA in patients with GCA.FDG-PET and CTA were acquired in all consecutive patients suspected for GCA. Results of FDG...

OBJECTIVE In Europe giant cell arteritis (GCA) is more common in Scandinavian countries than in southern regions. Epidemiological studies on GCA in other more distant countries have indicated a progressive increase in incidence. A regular cyclical pattern in incidence of GCA over 20 years has been reported in Olmsted County (Minnesota, USA). In contrast, no cyclical fluctuation has been recentl...

BACKGROUND Ultrasonography of temporal arteries is not commonly used in the approach of patients with suspected giant cell arteritis (GCA) in clinical practice. A meta-analysis of primary studies available through April 2004 concluded that ultrasonography could indeed be helpful in diagnosing GCA. We specifically re-examined the diagnostic value of the ultrasonography-derived halo sign, a dark ...

If there is no pain in the temporal artery, the diagnosis of giant cell arteritis (GCA) may be delayed and blindness may occur. Therefore, FDG-PET/CT is important as a modality for diagnosis of GCA. When GCA is suspected and F-18 FDG-PET/CT is performed, it is worthwhile to pay attention to shoulder and hip joints as polymyalgia rheumatica commonly presents with GCA.

OBJECTIVES One of the most prominent features of schizophrenia is relatively lower general cognitive ability (GCA). An emerging approach to understanding the roots of variation in GCA relies on network properties of the brain. In this multi-center study, we determined global characteristics of brain networks using graph theory and related these to GCA in healthy controls and individuals with sc...

OBJECTIVE To determine the risk of newly recorded myocardial infarction (MI) and stroke among incident GCA cases compared with controls from the general population. We also evaluated time trends during follow-up. METHODS We conducted a matched cohort study (1996-2010) of all patients with incident GCA from the province of British Columbia, Canada. We estimated incidence rates of MI and stroke...

OBJECTIVE The aim of this study was to examine potential risk factors for GCA in a nested case-control study based on two prospective health surveys. METHODS We used two population-based health surveys, the Malmö Preventive Medicine Program (MPMP) and the Malmö Diet Cancer Study (MDCS). Individuals who developed GCA after inclusion were identified by linking the MPMP and MDCS databases to sev...

Objective We aimed to evaluate whether the Leganés cognitive test (LCT) correlates with global cortical atrophy (GCA) and can be used as a surrogate for structural brain damage. Methods Atahualpa residents aged > 60 years identified during a door-to-door survey underwent MRI for grading GCA. Using multivariate generalized linear models, we evaluated whether continuous LCT scores correlated wi...
