Obj.ctives: To investigate the characteristics of the acute coronary syndromes underlying acute pulmonary oedema and their 30 day prognosis. Patients: 185 consecutive patients with acute coronary syndromes and acute pulmonary oedema admitted to a tertiary care centre. Main outcome and measures: Clinical, ECG, echocardiographic, enzymatic, and angiographic features were prospectively investigated. Results: Non-ST segment elevation myocardial infarction(NSTEMI) was the most frequent cause of acute pulmonary oedema(61%) followed by unstable angina(UA; 21%) and ST segment elevation myocardial infarction(STEMI; 18%). In each group, mean age was ≥70 years, but NSTEMI patients were the oldest and ≥65%of patients had chronic hypertension. Moreover, patients with NSTEMI and UA were older and had a higher incidence of diabetes, previous myocardial infarction, and moderate to severe mitral regurgitation but a similarly reduced ej.ction fraction(NSTEMI, 41%; UA, 39%; and STEMI, 39%) and increased incidence of diastolic dysfunction and rate of multivessel disease(94%, 87%, and 86%, respectively). However, patients with STEMI had a higher creatine kinase MB peak concentration(158 v 76 μg/l in the NSTEMI group, pj.ction fraction100 μg/l as the main prognostic markers(pj.ction fraction suggest a more extensive acute systolic loss.

The frequency distribution and severity of the cardiac disease underlying acute cardiogenic pulmonary edema(APE) to define appropriate subsequent diagnostic and management strategies were investigated in 216 consecutive patients. To this effect, the clinical, electrocardiographic, echocardiographic and angiographic characteristics were analyzed. Coronary artery disease was identified in 185 patients(86%)-146 with acute myocardial infarction-as the underlying cause, isolated valvular disease in 10(5%) and other causes in 21(11%). Most patients were elderly(≥70 years, 72%), hypertensive(71%)and diabetic(44%). Among coronary disease(CAD) patients, however, 105(57%) showed conduction disturbances in theECG(QRS >0.10 s) and 84(45%) had no anginal pain during pulmonary edema. A 2D echocardiogram showed a 30%incidence of moderate-severe mitral regurgitation in coronary disease and non-coronary disease patients, and a 67%incidence of reduced ej.ction fraction(< 50%), particularly in coronary disease patients(73%). A coronary angiography performed in 99 patients with coronary disease showed multivessel disease in 89(91%) with a 32%incidence of significant left main disease. Therefore, these findings demonstrate that coronary disease is the most common cause of acute pulmonary edema and it is associated with a distinctly high prevalence of multivessel and left main disease. This diagnosis, however, may often be overlooked if no serial enzymatic sampling is performed given the increased frequency of conduction abnormalities and lack of anginal pain.

作者： figueras j. Domingo E. Hermosilla E. 郝广华 Unitat Coronaria I Seccio d'H. Servei de Cardiologia Hospital General Vall d'Hebron P. Vall d'Hebron 119-129 08035 Barcelona Spain

Clinical and ECG prognostic markers, ischemic threshold(IT)-and extent of coronary disease were analyzed in 383 patients with unstable angina(UA) and correlated with long-term events. Patients >74 years or those with severe heart failure or previous revascularization procedures were excluded. There were 369 events in 245 patients: 87 deaths, 96 myocardial infarction(MI), 111 coronary artery bypass grafting(CABG), and 75 angioplasty procedures(PTCA). Follow-up was obtained in 367 hospital survivors(99%, 114(44) months) and ST depression on admission ECG, a modest enzyme rise, refractory angina( >2 episodes), two to three vessel coronary disease and a reduced IT(≤130 beats/min) were each associated with cardiac events. A multivariate analysis, however, showed refractory angina(p< 0.001) and multivessel disease(p< 0.001) as most significant predictors. After their exclusion, IT was most relevant predictor(p< 0.001). However, the predictive value of these markers was essentially centered on first-year events(249, 67%). Moreover, refractory angina, minor enzyme rise and admission ST depression were each highly correlated with a reduced IT(p< 0.006) and with multivessel disease(p< 0.0001). Therefore, these findings underscore that the prognostic value of conventional clinical markers in patients with UA is limited to first-year events and that their remarkable correlation with extensive coronary disease and reduced coronary reserve reveal the anatomical substrate of this prognostic significance.

AIM:To describe and evaluate the efficacy of Ahmed glaucoma valve implantation(AGV)combined with pars plana vitrectomy(PPV)in a single surgical act for the treatment of advanced neovascular glaucoma(NVG).METHODS:Retrospective observational case series included 51 eyes from 50 patients with severe NVG treated with PPV,AGV,and panretinal photocoagulation and/or cryotherapy in a single surgical act during a 13-year period(2005-2018).Preoperative,intraoperative and postoperative data at day 1 and months 1,3,6,21,and 24 were systematically *** of surgical success was stablished at IOP between 6 and 21 mm Hg with or without topical ***:Main indications for surgery were NVG secondary to proliferative diabetic retinopathy(39.2%)and central retinal vein occlusion(37.3%).Mean(±SD)preoperative IOP was 42.0±11.2 mm Hg decreasing to 15.5±7.1 mm Hg at 12 mo and 15.8±9.1 mm Hg at 24 mo of follow *** incidence of success of IOP control was 76.0%at first postoperative month,reaching 88.3%at 6 *** of successful IOP control at long term was 74.4%at 12 mo and 71.4%at 24 *** evisceration for unsuccessful NVG management was required in 1 case(2.0%).CONCLUSION:Combination of AGV implantation and PPV in a single act may be a suitable option for severe forms of NVG in a case-by-case basis for effective IOP control and a complete panretinal photocoagulation.

Microcystic adnexal carcinoma (MAC) is a slow growing, locally aggressive sweat gland tumor. It predominantly affects the face and tends to recur despite local excision. Microscopically, MAC is characterized by a stratified proliferation of microcysts, cords, and ducts of cells that show squamous or adnexal differentiation. Atypia andmitoses are almost completely absent and metastatic deposits are rare and mostly limited to the regional lymph nodes; rather than real metastases, they might be the result of local extension of the tumor through perineurial spaces. We report a case of adnexal carcinoma with architectural features of MAC that displayed also marked nuclear pleomorphism and hyperchromasia with squamous pearl formation and a widespread strong p53 immunoreaction. The lesion behaved as a high-grade neoplasmwith rapid growth, carcinosarcomatous metaplastic transformation in a relapse, and what were clinically suspected to be metastases. The literature contains several other examples reported as metastatic highgrade MAC, one of them with widespread distant metastases. We therefore want to sound an alert about the possible existence of tumors displaying microscopic findings characteristic of the aggressive forms of sweat gland carcinoma (nuclear pleomorphism and hyperchromasia, vascular invasion, and necrosis) in addition to architectural features of MAC. Whether these tumors should be called high-gradeMACs or belong to a separate category remains an open issue until more cases are reported and bridge cases are eventually documented.
