Objective: The aim of the study.was to assess the effects of aortic valve replacement (AVR) in patients with aortic stenosis (AS) or regurgitation (AR) and left ventricular (LV) dy.function. Patients and methods: Retrospective analy.is identified 75 consecutive patients with left ventricular ejection fraction (LVEF) assessed by.echocardiography.y.cardial infarction or concomitant valvular disorders other than aortic disease. Follow-up evaluated the New y.rk Heart Association (Ny.A) functional class, LVEF and survival rate. Results: Mean ages were respectively.56.5 ± 9.3 and 47.9 ± 11.7 y.ars in AS and AR groups, p = 0.001. Before surgery. 88% and 75% of patients were in Ny.A III-IV respectively.in AS and AR. In the AS group, the mean LVEF and aortic valve area (AVA) were respectively.32.2% ± 8% and 0.65 ± 0.15 cm2. AR group had a mean LVEF of 33.8 ± 6.7% and a mean LV sy.tolic diameter of 62 ± 8.8 mm. All patients underwent AVR under cardiopulmonary.by.ass. There were 5 operative deaths (12.5%) in AS group and 6 (17.6%) in AR group, p = 0.57. LVEF increased to 49% ± 14.7% and 51.2% ± 10.9% in the AS and AR groups after echocardiography.control. The survival rates at 1, 5 and 10 y.ars were respectively.94.4%, 87% and 80% in AS group and 95.2%, 93% and 89% in AR group. Conclusion: Despite higher perioperative mortality.in patients with aortic valve disease (AS or AR) and LV dy.function, long-term outcome is excellent. We, therefore, conclude that AVR can be performed and it should not be denied to patients on the basis of low EF alone.

Aim: Comparing the results of acute phase infectious endocarditis surgery.between two periods. Methods and Results: The study.is about 2 series, series A between 1993 and 1997, and series B between 1998 and 2012, respectively.13 and 51 patients. The two periods were similar concerning the number of patients per y.ar, which was 3.12 cases/y.ar for series A and 3.64 cases/y.ar for series B. The authors noted a change in epidemiological profile, with an increase of median age (31 y.o for series A and 37 y.o for series B), and the emergency.of endocarditis on prosthetic valve (none on series A and 8 cases for series B). Surgical indications and results didn’t change too much, hospital mortality.rate was 15.3% for series A and 17.6% for series B. Conclusion: Infectious endocarditis is still a major public healthcare problem in developing countries, despite the development of diagnostic tools and patient care. Prevention is still the major asset in the treatment of this disease.

Breast cancer appears to be a disease of both the developing and developed worlds. Among Moroccan women, breast cancer represents 34.4% of all cancers seen in women. This study.aimed to give an overview of the knowledge, attitudes and perceptions related to breast cancer among Moroccan women. To our knowledge there is no previous study.in Morocco to assess Moroccan women awareness of breast cancer. A national Cross-sectional study.started in July.2011 based on eligible women for early.detection programs in basal health centers from five Moroccan regions. A self-filled questionnaire was used to collect data outside working time. Knowledge was assessed using 24 true-false items. The questions were asked about sy.ptoms and risk factors of breast cancer. A score ranging from 0 to 24 was calculated by.weighting each item 1 point. Then the score was dichotomized according to the threshold 12 （50% correct answers）. The study.included 1,444 women from the regions of Rabat, Casablanca, Marrakech, Fez and Meknes. The average age was 40.6 ~ 10 y.ars, 2 women with a minimum age of 17 y.ars and a 1 with a maximum age of 86 y.ars. At the bivariate analy.is using chi-square test we found that Marital Status, Social Security. Education, Origin, Sport, Personal History.of Cancer, Medical and Surgical personal History.were associated with knowledge score. At the multivariate analy.is （Logistic regression）, we found that Social Security. Education, Origin, Sport were associated to knowledge score at the final model. This study.has important implications for health care providers. The poor knowledge of risk factors and practice of breast screening leads to late stage presentation at diagnosis of breast cancer.
