Background and Objectives: The prevalence of heart failure (HF) increases with age. Even though the mortality of patients ≥ 80 years of age with HF and preserved left ventricle ejection fraction (LVEF) is very high, the predictor variables are not well-known. The main goal of this study was to evaluate the mortality predictor factors in this subgroup of the elderly population., Patients and Methods: An observational and prospective study of patients hospitalized due to HF with preserved LVEF has been conducted. The demographic, clinical, functional and analytic factors were evaluated when the patients were admitted with special attention to the co-morbidities. The primary endpoint was the total mortality in the subgroup of patients ≥ 80 years of age after a year of follow-up. The predictor variables were studied by means of a multivariate Cox regression model., Results: From a total of 218 patients with an average age of 75.6 (±8.7) years of age, 75 patients (34.4%) were ≥ 80 years. The mortality rate of patients ≥ 80 years of age totaled 42.7%, in relation to 26.6% for the lower age group (log-rank<.001). After a multivariate analysis using the Cox regression model in patients ≥ 80, the serum urea levels above the average (hazard ratio [HR] 3.93; 95% confidence interval [95% CI] 1.58-9.75; P = .003), the age (HR 1.17; 95% CI 1.07-1.28; P<.001), the hyponatremia (HR 3.19; 95% CI 1.51-6.74; P = .002) and a lower score on the Barthel index (BI) (HR 1.016; 95% CI 1.002-1.031; P = .034) were independent mortality predictors after an one-year follow-up., Conclusions: Serum urea levels, age, hyponatremia and a low BI score could be proposed as independent mortality predictors in patients ≥ 80 of age hospitalized for HF with preserved LVEF., (Copyright © 2012 Elsevier España, S.L.

Objective: To evaluate the diagnostic accuracy of the percutaneous fine needle aspiration cytology (FNAC) for mediastinal lesions by using histology or follow-up clinical diagnosis as gold standard., Patients and Methods: CT-guided percutaneous FNAC was performed on 131 patients with mediastinal lesions. Helical CT was used with 3-10 mm image thickness range and low radiation dose (40 mAs, 120 kV). Samples were immediately examined by a cytologist to determine if they were representative. Histological samples were obtained by means of biopsy or resection specimens in 73 patients and clinical follow-up in 50., Results: The material was satisfactory for diagnosis in 126 patients (95.2 %), in whom 103 lesions (78.6%) were considered malignant (62 primary tumours and 41 metastases) and 23 (17.6%) benign. In the 123 patients with clinical monitoring or pathological diagnosis, using FNAC led to the identification of malignancy with a sensitivity of 95.2 % (95%CI: 89.2-97.9%), specificity 84.2% (95%CI: 62.4-94.5%), positive predictive value 97.1% (95%-CI: 91.7-99.0%), negative predictive value 76.2% (95%CI: 54.9-89.4%), likelihood-ratio positive 6.03 (95%CI: 2.13-17.05) and accuracy 93.5% (95%CI: 87.7-96.7%). Pneumothorax was the most frequent complication (3 cases). There was good agreement between the cytological findings and the histological findings, not only for malignant lesions (kappa coefficient: 0.641) but also for benign (kappa 0.607)., Conclusions: CT-guided percutaneous FNAC is a safe and effective technique for the diagnosis of the mediastinal masses, with a high diagnostic yield for malignancy depicting., (Copyright 2009 SEPAR.

We present the case of an 60-year-old male patient that after a acute myocardial infarction inferior diagnostic was subjected to a fibrinolysis with streptokinase. The evolution from the cardiologic point of view was favourable, but at fourth day postacute myocardial infartion he starts with peripherics vasculars symptoms, pain and livedo reticularis in lower part of the body. A symptomatic treatment was made requiring amputation of his fifth right toe. The evolution was towards healing without any organic afectation at another level.

The coexistence of organ-specific and nonorgan-specific autoimmune diseases is an interesting phenomenon. A 52-year-old woman was admitted with fever, general discomfort, polyarthritis, and Raynaud's phenomenon. Physical examination revealed a goiter of stony consistency, hardening, paleness, and atrophy of the skin on the face and upper limbs, and blood hypertension (180/110 mmHg). The biological data included leukopenia, moderate anemia, and a very high sedimentation rate. The latex test was positive (+++); LE cells positive (+); hypergammaglobulinemia (3.5 g); antinuclear antibodies, 1/1280 with an immunofluorescence granular pattern; antithyroid antibodies, 1/160. There was pulmonary, renal, and gastrointestinal involvement compatible with scleroderma, which was confirmed by skin biopsy. A thyroidectomy revealed the existence of a papillary carcinoma with thyroiditis. Responde to treatment with immunosuppressive agents, hypotensive drugs, and thyroid substitution therapy was initially good. The patient was readmitted 8 months later with general discomfort and a severe hyperproteinemia (10 g/100 ml), including 65 percent gammaglobulin and requiring various sessions of plasmapheresis. The patient was discharged, but died suddenly 4 months later. The association of lupus and scleroderma in this patient is discussed and the possibility of its being a mixed connective tissue disease is discarded. The association of this condition with Hashimoto's thyroiditis, and the latter with papillary carcinoma of the thyroid are analyzed. The peculiar features of this case are pointed out. The authors postulate that the cause of the sudden death was a vascular cerebral complication induced by the extreme hyperproteinemia.
