Recurrent pericardial effusion after cardiac surgery: the use of colchicine after recalcitrant conventional therapy

Pericardial effusion represents a common postoperative complication in cardiac surgery. Nonetheless, it can be resistant to conventional therapy leading to prolonged in-hospital stay and worsening of clinical conditions

Pretreatment with corticosteroids attenuates the efficacy of colchicine in preventing recurrent pericarditis: A multi-centre all-case analysis

Aims Effective prevention of recurrent pericarditis remains an important yet elusive goal. Corticosteroid therapy often needs to be continued for a prolonged period and causes severe side effects. We performed a multi-centre all-case analysis to investigate the efficacy of colchicine in preventing subsequent relapses of pericarditis, and addressed the hypothesis that pretreatment with corticosteroids may attenuate the beneficial effect of colchicine. Methods and results One hundred and forty published and unpublished cases of patients treated with colchicine after at least two relapses of pericarditis were aggregated from European centres. Of those 119 were included in the study group. Only 18% of the patients had relapses under colchicine therapy, and 30% after its discontinuation. There were significantly more relapses among mate patients after colchicine treatment (36 vs. 17%, P = 0.046), and those with previous corticosteroid treatment (43 vs. 13%, P = 0.02). Multivariate logistic regression analysis identified previous corticosteroid therapy (OR 6.68, 95% Cl: 1.65-27.02) and mate gender (OR 4.20, 95% Cl: 1.16-15.21) as independent risk factors for recurrence following colchicine therapy. Conclusion Treatment with colchicine is highly effective in preventing recurrent pericarditis, white pretreatment with corticosteroids exacerbates and extends the course of recurrent pericarditis

Frequency of left ventricular hypertrophy in non-valvular atrial fibrillation

Left ventricular hypertrophy (LVH) is significantly related to adverse clinical outcomes in patients at high risk of cardiovascular events. In patients with atrial fibrillation (AF), data on LVH, that is, prevalence and determinants, are inconsistent mainly because of different definitions and heterogeneity of study populations. We determined echocardiographic-based LVH prevalence and clinical factors independently associated with its development in a prospective cohort of patients with non-valvular (NV) AF. From the "Atrial Fibrillation Registry for Ankle-brachial Index Prevalence Assessment: Collaborative Italian Study" (ARAPACIS) population, 1,184 patients with NVAF (mean age 72 \ub1 11 years; 56% men) with complete data to define LVH were selected. ARAPACIS is a multicenter, observational, prospective, longitudinal on-going study designed to estimate prevalence of peripheral artery disease in patients with NVAF. We found a high prevalence of LVH (52%) in patients with NVAF. Compared to those without LVH, patients with AF with LVH were older and had a higher prevalence of hypertension, diabetes, and previous myocardial infarction (MI). A higher prevalence of ankle-brachial index 640.90 was seen in patients with LVH (22 vs 17%, p = 0.0392). Patients with LVH were at significantly higher thromboembolic risk, with CHA2DS2-VASc 652 seen in 93% of LVH and in 73% of patients without LVH (p <0.05). Women with LVH had a higher prevalence of concentric hypertrophy than men (46% vs 29%, p = 0.0003). Logistic regression analysis demonstrated that female gender (odds ratio [OR] 2.80, p <0.0001), age (OR 1.03 per year, p <0.001), hypertension (OR 2.30, p <0.001), diabetes (OR 1.62, p = 0.004), and previous MI (OR 1.96, p = 0.001) were independently associated with LVH. In conclusion, patients with NVAF have a high prevalence of LVH, which is related to female gender, older age, hypertension, and previous MI. These patients are at high thromboembolic risk and deserve a holistic approach to cardiovascular prevention

Prognosis of Idiopathic Recurrent Pericarditis as Determined from Previously Published Reports

After a systematic review of all publications on recurrent pericarditis from 1966 to 2006, we identified 8 major clinical series including a total of 230 patients with idiopathic recurrent pericarditis (mean age 46 years, men/women ratio: 0.9). After a mean follow-up of 61 months, the complication rate was 3.5% cardiac tamponade and 0% constrictive pericarditis and left ventricular dysfunction. The overall life prognosis is excellent in idiopathic recurrent pericarditis and complications are uncommon. In conclusion constrictive pericarditis was never reported despite numerous recurrences, and the risk is lower than in idiopathic acute pericarditis (approximately 1%). Thus, it is important to reassure patients on their prognosis, explaining the nature of the disease, and the likely course. Therapeutic choices should take into account of the overall good outcome of these patients, including less toxic agents

La Digametia Femminile in Artemia Salina

RIASSUNTOVengono per la prima volta individuati i cromosomi del sesso in Artemia salina e viene riconosciuta citologicamente la digametia femminile (♀ XY, ♂ XX).Dalle osservazioni comparative tra il corredo del biotipo diploide anfigonico e quello diploide partenogenetico, entrambi di Cagliari, risulta che: 1. Nel biotipo partenogenetico, i cromosomi hanno dimensioni maggiori rispetto a quelli del biotipo anfigonico, riconferma questa di vecchi dati.2. I cromosomi del biotipo partenogenetico hanno maggiore elettivita per il colorante.3. Riguardo agli eterocromosomi, i rapporti in lunghezza tra questi e gli autosomi non sono uguali nei due corredi. Esiste una maggior lunghezza proporzionale degli eterocromosomi del corredo partenogenetico che dimostra essere questo biotipo un mutante cromosomico rispetto a quello anfigonico
