O Valor Prognóstico da Resposta Neutrofílica na Era da Reperfusão Mecânica do Enfarte Agudo do Miocárdico

BACKGROUND: In ST-segment elevation myocardial infarction (STEMI) patients treated with primary angioplasty, neutrophil response and its prognostic significance are not entirely understood. METHODS: We retrospectively studied 305 consecutive and non-selected STEMI patients. They were divided into three groups according to the maximum neutrophil percentage in the first 48 hours. We compared baseline demographic characteristics, coronary disease risk factors, cardiac history, clinical presentation, therapeutics administered and clinical evolution. We then assessed survival in the three groups and determined predictors of 30-day mortality. Group 1 (G1) had a mean age of 57 +/- 14 years and showed mean neutrophilia of 73.3%, Group 2 (G2) 61 +/- 13 years and 79.9%, and Group 3 (G3) 66 +/- 13 years and 84.2%. We compared outcomes and 30-day mortality between the groups. RESULTS: Mean age rose with increased neutrophil response. There were no statistically significant baseline differences between the groups except for more smokers in Groups 1 and 2, and more patients presenting with Killip class > or = 2 and fewer with uncomplicated evolution in Group 3. During 30-day follow-up there were 19 deaths (G1=1, G2=3 and G3=15). In univariate analysis mortality predictors were age > or = 75 years, anterior STEMI, maximum creatinine kinase > or = 2500 UI/L, culprit lesion in proximal anterior descending artery, incomplete revascularization, Killip > or = 2 at presentation, and being in G3. After multivariate regression analysis independent predictors were age > or = 75 years, incomplete revascularization and being in G3. CONCLUSION: In myocardial infarction patients undergoing mechanical revascularization, an intense neutrophil response (routinely, easily and inexpensively assessed) is related to worse short-term prognosis.

Postmenopausal Bleeding and Endometrial Changes: Clinical Significance?

Introduction: Postmenopausal bleeding is a common complaint from women seen in general practice, although majority of them, will have no major problem. Objective: Study of endometrium in postmenopausal women with suspicious sonographic endometrial changes. Comparison of findings in asymptomatic women and those who reported metrorrhagia. Methods: Consultation of outpatient medical records of 487 women undergoing endometrial study (sonohysterography, hysteroscopy), between January/2004 and July/2010. Patients were subdivided into two groups: women with (G1) and without (G2) complaints of postmenopausal metrorrhagia. Results: G1 and G2 comprises 78 and 409 women, respectively. G1: 23.1% normal uterine cavity, 74.3% benign pathology (majority endometrial polyps) and 2.6% of them endometrial carcinoma. G2: 14.4% normal uterine cavity, 83.7% benign pathology (majority endometrial polyps), 1.4% endometrial hyperplasia and endometrial carcinoma in 0.49%. Conclusion: Postmenopausal metrorrhagia is associated with an increased risk of endometrial malignancy, in relation to asymptomatic, although represents a minority of the population. To highlight the existence of premalignant and malignant pathology in asymptomatic endometrial thickening.
