Temporal arteritis (TA) is the most common form of systemic vasculitis. Its diagnosis is based on criteria proposed by the American College of Rheumatology (1990), and its treatment is high-dose corticosteroids. Our objective is to assess the cost of diagnosing TA, and secondarily, cost-effective analysis of different diagnostic strategies (clinical, biopsy, doppler ultrasound) and therapeutic strategies (corticosteroid suspension)., Material and Method: Observational, retrospective study has been carried out on patients with AT (2012-2021). Demographic data, comorbidities, signs and symptoms suggestive of AT were collected. AT was diagnosed with a score ≥ 3 according to American College of Rheumatoloy criteria (ACR-SCORE). The costs of diagnosis and treatment modification were analysed., Results: Seventy-five patients have been included, median age 77 (46-87) years. Headache, temporal pain and jaw claudication were significant for the diagnosis of TA. Patients with a halo on Doppler ultrasound and a positive biopsy have significantly elevated ESR and CRP compared to patients who do not. The cost of the AT diagnosis was 414.7 euros/patient. If we use ACR-SCORE ≥ 3-echodoppler it is 167.2 є/patient (savings 59.6%) and ACR-SCORE ≥ 3-biopsy 339.75 є/patient (savings 18%). If the corticosteroid was removed and a biopsy was performed, 21.6 є/patient (94.7% savings), if the corticosteroid was removed and Doppler ultrasound was performed, 10.6 є/patient (97.4% savings)., Conclusions: Headache, temporary pain and jaw claudication are predictors of AT. Elevated ESR and CRP are predictors of positive biopsy and presence of halo on ultrasound. The uses of ACR-SCORE ≥ 3 with Doppler ultrasound or biopsy, and with corticosteroid suspension, are cost-effective., (Copyright © 2023 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Background and Objective: Methicillin-resistant Staphylococcus aureus (MRSA) is associated with an increasing morbimortality when compared with other microorganisms. The aim of this study was to examine the complications and prognosis of the presence of MRSA in vascular patients with amputation of lower limbs., Patients and Method: We included patients who had lower extremity amputation in our department in 2004 and displayed positive surgical wounds cultures. We compared patients with MRSA positive cultures with other microrganisms. We evaluated general characteristics, operative indications, surgical wounds microbiology, reamputations, morbimortality and mean time of stay in hospital., Results: 117 patients (median age 73, 68% male) underwent lower extremity amputation. 82 of them had positive cultures and MRSA were isolated in 30% cases. Two two groups were comparable and no statistical differences were found in relation to reamputation rate, morbimortality and mean time of stay in hospital., Conclusion: Presence of MRSA does not represent an additional risk of reamputation or an increase of postoperative complications. Careful wound surveillance, through wound debridement and optimal administration of antibiotics must be applied to all patients, regardless of the bacterial flora.
