Abstract

Background and Objectives : Mitral annular calcification (MAC) is associated with osteoporosis and there is evidence of reduced bone mineral density (BMD) in patients with renal stone formation (RSF). Therefore, we designed this study to test if RSF was associated with MAC and if this association could be linked to bone resorption. Methods : Fifty-nine patients (mean age, 41.5 years) with RSF and 40 healthy subjects (mean age, 44.2 years) underwent screening for MAC and BMD, and measuurements were taken of serum and urine electrolytes, parathyroid hormone, alkaline phosphatase and urine dypyridoline. Results : MAC was diagnosed in 11 (18%) patients with RSF compared with 1 (2.5%) control (P=.01). Urine phosphorus, magnesium, sodium, potassium and chloride levels were lower (P < .001, P=.02, P < .001, P < .001 and P < .001, respectively), but serum alkaline phosphatase, calcium and potassium levels were higher (P=.008, P=.007 and P=.001, respectively) in patients with RSF versus those without RSF. None of these abnormalities were found in patients or subjects with MAC. Urine pyridoline levels were higher and T-scores were more negative (more osteopenic) in patients and subjects with MAC than in those without MAC (P=.01 and P=.004, respectively). In a multivariate analysis, only T-scores and urine dipyridoline level were predictive of MAC (P=.03 and P=.04, respectively). Conclusions : Screening for MAC and bone resorption markers in patients with RSF demonstrated a high incidence of MAC in these patients. The presence of MAC in patients with RSF was associated with bone resorption markers. This seemingly complex interrelationship between RSF, MAC and bone loss needs to be clarified in further studies.

Abstract

External electrical cardioversion was first performed in the 1950s. Urgent or elective cardioversions have specific advantages, such as termination of atrial and ventricular tachycardia and recovery of sinus rhythm. Electrical cardioversion is life-saving when applied in urgent circumstances. The succcess rate is increased by accurate tachycardia diagnosis, careful patient selection, adequate electrode (paddles) application, determination of the optimal energy and anesthesia levels, prevention of embolic events and arrythmia recurrence and airway conservation while minimizing possible complications. Potential com-plications include ventricular fibrillation due to general anesthesia or lack of synchronization between the direct current (DC) shock and the QRS complex, thromboembolus due to insufficient anticoagulant therapy, non-sustained VT, atrial arrhythmia, heart block, bradycardia, transient left bundle branch block,myocardial necrosis, myocardial dysfunction, transient hypotension, pulmonary edema and skin burn.Electrical cardioversion performed in patients with a pacemaker or an incompatible cardioverter defibrillator may lead to dysfunction, namely acute or chronic changes in the pacing or sensitivity threshold.Although this procedure appears fairly simple, serious consequences might occur if inappropriately performed.

Abstract

BACKGROUND: The purpose of this study was to determine the long‐term prognostic implications of incidental pleural effusion (PE) detected during echocardiographic examination and its relationship with concomitant diseases. HYPOTHESIS: The study hypothesis is to test whether incidental pleural PE detected during echocardiographic examination be used as a prognostic marker. METHODS: The study was performed by evaluating patient records (N = 251) in whom PE was incidentally detected during echocardiographic examination in a tertiary hospital between 1999 and 2012. The patients were classified into 4 major groups according to the concomitant primary disease: malignancy, and cardiovascular, renal, and pulmonary diseases. The total survival time was obtained from hospital records for patients who died during the hospital stay and social security institution records for patients with out‐of‐hospital death. RESULTS: One‐year and 5‐year life expectancies of PE cases concomitant with different disorders were as follows; heart failure (n = 151), 81% and 70%; malignancies (n = 45), 53% and 44%; pulmonary diseases (n = 37), 89% and 78%; renal diseases (n = 18), 100% and 83%; respectively. PE associated with heart failure, renal disease, and pulmonary disease had similar (P > 0.05 for all) and favorable outcomes compared to PE associated with malignancies (P < 0.001). CONCLUSIONS: The prognosis of incidental PE was the worst in patients with concomitant malignancies; however, PE associated with nonmalignant diseases including heart failure, pulmonary disease, and renal disease have similar and favorable outcomes.
