RESUMO
Rapid urbanization is a key driver of the unique set of health risks facing urban populations. One of the most critical health hazards facing urban women is intimate partner violence (IPV). In post-conflict urban areas, women may face an even greater risk of IPV. Yet, few studies have examined the IPV experiences of urban-dwelling, conflict-affected women, including those who have been internally displaced. This study qualitatively examined the social and structural characteristics of the urban environment that contributed to the IPV experiences of women residing in post-conflict Abidjan, Côte d'Ivoire. Ten focus groups were conducted with men and women, both internally displaced (IDPs) and non-displaced. Lack of support networks, changing gender roles, and tensions between traditional gender norms and those of the "modern" city were reported as key contributors to IPV. Urban poverty and with it unemployment, food insecurity, and housing instability also played a role. Finally, IDPs faced heightened vulnerability to IPV as a result of displacement and discrimination. The relationship between economic strains and IPV are similar to other conflict-affected settings, but Abidjan's urban environment presented other unique characteristics contributing to IPV. Understanding these factors is crucial to designing appropriate services for women and for implementing IPV reduction interventions in urban areas. Strengthening formal and informal mechanisms for help-seeking, utilizing multi-modal interventions that address economic stress and challenge inequitable gender norms, as well as tailoring programs specifically for IDPs, are some considerations for IPV program planning focused on conflict-affected women in urban areas.

Glutamate and adenosine both modulate adenylyl cyclase activity through interaction of their specific receptors with stimulatory or inhibitory G-proteins. Guanine nucleotides (GN), which modulate G-protein activity intracellularly, are also involved in the inhibition of glutamate responses, acting from the outside of the cells. We had previously reported that glutamate inhibits adenosine-induced cyclic AMP (cAMP) accumulation in slices obtained from the optic tectum of chicks. In the present study we investigated the interaction of GN with these two neurotransmitters and found that GN inhibit the inhibitory effect of glutamate on adenosine-induced cAMP accumulation and potentiate adenosine-induced cAMP accumulation. These effects were observed with 5'-guanylylimidodiphosphate (GppNHp) or GMP, but not with guanosine (the nucleoside). Besides, these interactions of GN occur via a metabotropic glutamate receptor (mGluR) sensitive to (1 S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid (1 S,3R-ACPD) but not to L-2-amino-4-phosphonobutyrate (L-AP4). These effects were partially modulated by a mGluR antagonist, (RS)-alpha-methyl-4-carboxyphenylglycine ((RS)M-CPG), and by an adenosine receptor antagonist, 8-phenyltheophylline. GN only potentiated the adenosine response when adenosine was acting through its receptor positively linked to adenylyl cyclase. Therefore, the data show that guanine nucleotides not only inhibit glutamate-induced responses, but also stimulate adenosine-induced responses, a fact that may contribute to the understanding of the physiological functions of guanine nucleotides.

A 33-year-old female patient, with a 4-year history of hypertension plus a 3-year history of systemic lupus erythematosus, who had been taking high dosages of corticosteroids, has shown repetitive respiratory infections and congestive heart failure for the past 8 months. Angiocardiography confirmed the diagnosis of aortic insufficiency with aneurysmatic dilation of Valsalva's posterior sinus, ascending aorta of normal diameter and normal coronary arteries. Aortic dissection causing aortic insufficiency due to collapse of aortic leaflets was spotted during the surgery and was corrected by a bovine pericardial tube and suspension of aortic valve. The postoperative (PO) period was complicated by left-sided seizures followed by left hemiparesis and respiratory infection. She was discharged on the 25th PO day with mild left hemiparesis and in functional class I (NYHA), using medicines. We emphasize the need to consider the diagnosis of aortic dissection in patients with systemic lupus erythematosus and aortic insufficiency, specially in those who have a history of systemic arterial hypertension and long-term corticosteroid therapy.

PURPOSE: To evaluate percutaneous mitral balloon valvuloplasty (PMBV) in surgical high risk patients. METHODS: Twenty (12%) patients out of 172 submitted to a PMBV were considered high surgical risk cases; 17 (85%) were women and mean age was 43 (18-69). Thirteen (65%) were in acute pulmonary edema (3 were pregnant, 2 had previous cerebrovascular event, 1 had pulmonary thromboembolism and other had chronic renal failure), and 7 (35%) were in functional class (CF) III (2 had coronary artery disease, 2 severe obesity, 1 pulmonary neoplasia, 1 cardiac cachexia and one with previous cerebrovascular event). All patients underwent PMBV through transseptal technique. Double balloon was used in 10 (50%) patients; Inoue balloon in 5 (25%), mono-foil in 3 (15%) and bi-foil in 2 (10%). RESULTS: Seventeen (85%) obtained success and 2 (10%) had clinical improvement. The hemodynamic results pre versus post-PMBV showed: left atrium pressure (LAP) mmHg 28.2 +/- 10.0 x 15.2 +/- 9.2 (n = 20) (p < 0.001), mitral medium gradient (G) mmHg 21.2 +/- 10.7 x 10.7 +/- 6.7 (n = 18) (p < 0.001), mitral valve area (MVA) cm2 0.73 +/- 0.3 x 1.73 +/- 0.6 (n = 11) (p < 0.001), pulmonary artery pressure mmHg 52.0 +/- 18.2 x 40.1 +/- 14.7 (n = 18) (p < 0.001) and cardiac index L/min/m2 2.1 +/- 0.4 x 2.5 +/- 0.6 (n = 14) (p < 0.001). Comparative echocardiography results pre, post and 6 months after PMBV showed: MVA 1.06 +/- 0.39 x 1.92 +/- 0.51 x 1.65 +/- 0.5 and G 13.8 +/- 4.7 x 7.3 +/- 3.6 x 7.3 +/- 4.4. There were two immediate deaths (pulmonary thromboembolism and multiple organs failure) and other after hospital discharge. The complications were: 2 (10%) patients with neurological complications, 1 (5%) atrial septal defect and other right atrium perforation (5%). CONCLUSION: PMBV offers an alternative to surgical treatment in high risk surgical patients and the results are maintained in the 6 month follow-up.

PURPOSE: To demonstrate the importance of the preservation of mitral annulus-chordae tendineae-papillary muscles continuity in mitral valve replacement. METHODS: We studied 21 patients who were submitted to mitral valve replacement, divided in two randomized groups: group 1, 12 cases who undergone mitral valve replacement, with preservation of the posterior leaflet and correspondent chordae tendineae; and group 2-9 cases who undergone conventional mitral valve replacement, excising the mitral valve apparatus. The left ventricular function was studied both, in the pre and post operative period, by echocardiography, cardiac catheterization, and radioisotopic study. The statistical analysis was done by the Wilcoxson's test. RESULTS: There were no early post operative deaths. Analyzing the results of the ejection fraction by the radioisotopic study we found a significant difference (p = 0.03) between the percentual decrease of the two groups. The results of the fractional shortening were higher in group 1 than in group 2, however not significant. The left ventricular diastolic diameters average was lower in group 1 than in group 2, so as the left atrium diameter. We found a decrease in left ventricular end-diastolic pressure in group 1, however there was an increase in group 2, by the cardiac catheterization. There was a proportional increase in group 1 both in lung artery and lung capillary pressures. There was a significant difference (p = 0.05) between the average values of right ventricular diastolic pressure. CONCLUSION: There is better preservation of left ventricular function in group 1.

PURPOSE: The study of frequency, modalities and course of neurological complications of infective endocarditis (IE), as well as the current indication and value of supplementary examinations. METHODS: Sixty-three patients with IE, 39 with native valve and 24 with valvar prosthesis, were prospectively studied; the mean age was 42 years and 45 (71.4%) were males. Two groups were formed: A) 41 patients without neurological events and B) 22 patients who presented 28 neurological events before or during hospitalization: ischemic cerebrovascular accident 20, hemorrhagic cerebrovascular accident 2, meningeal hemorrhage 2, meningitis 2, brain abscess 1 and seizure 1. All patients were submitted to neurological clinical examination; 57 computerized tomographies of the cranium, 28 arteriographies and 32 cerebrospinal fluid analysis were performed. RESULTS: The incidence of neurological events corresponded to 34.92% of IE patients, with a clear predominance (85.71%) of vascular as compared to infectious manifestations. Mortality was 2.32 times higher in group B patients (22.73% x 9.76%), albeit p = 0.256, and was not related to staphylococcal etiology. The neurological events were not related to sex, age and presence of valvar prosthesis. The presence of neurological complications was greater (p = 0.047) in patients with simultaneous infections in two valves (mitral and aortic) and also (p = 0.00884) in those with IE in prosthesis implanted for less than three months. All supplementary neurological examinations in group A were normal. CONCLUSION: 1) Occurrence of neurological events is a factor which influences the prognosis of IE; 2) supplementary neurological examinations did not reveal subclinical neurological complications; 3) neurological complications were significantly more frequent in patients with simultaneous mitral and aortic valve IE; 4) IE in prosthesis implanted for less than 3 months has a greater probability to develop a neurological picture as compared to IE in prosthesis implanted for more than 3 months.

A 56 years old man was submitted to an aortic replacement with mechanical prosthesis and to saphenous vein graft to the right coronary artery. He developed respiratory insufficiency after surgery which was finally related to bilateral diaphragmatic paralysis whose diagnosis was confirmed through thorax ultrasonography. The patient remained under ventilatory assistance with positive pressure for 75 days. The introduction of thorax ventilatory negative pressure (VNP), jacket type, allowed the tracheostomy closure. The patient gradually recovered his spontaneous breathing and was discharged after 90 days with instructions to use VNP at night. He returned to his normal professional activities, without auxiliary respiratory support, 40 days after his discharge.

PURPOSE: To study the characteristics of patients undergoing catheter-balloon mitral valvoplasty (CBVM) procedure who needed surgical intervention after CBMV. PATIENTS AND METHODS: One hundred and five patients submitted a CBMV were divided in to Group I (GI) of eighteen surgical patients and Group II (GII) of eighty-seven non-surgical patients. The following parameters were analyzed. 1) age; 2) sex; 3) mitral valve area (MVA) and mean transvalvular gradient (G) by echodopplercardiography (2D); 4) Character of CBMV; 6) Relation of time between CBMV and Surgery with surgical indication; 7) Surgical findings; 8) Surgical procedure and 9) Post-operative evolution. RESULTS: Mean age of 34 (17-56) years old in GI and 33 (15-69) years old in GII; 2) Similar distribution of men and women in GI and GII; 3) Similar MVA and G in GI and GII; 4) 100% of elective character in GI and 94% in GII; 5) Transseptal via in 17 (94%) of GI and 87 (83%) of GII, retrograde arterial via in 1 (5.5%) of GI and in another (1%) of GII; 6) immediate: cardiac tamponade (28%); until 30 days: unsuccessful CBMV (39%); mitral insufficiency (MI) post-CBMV (11%), cardiac tamponade (5.5%), between 30 and 60 days: MI post-CBMV (22%), Mitral restenosis post-CBVM (5.5%); 7) Mitral stenosis (72%), MI post-CBVM (22%), hemopericardium (6%); 8) Mitral Commissurotomy (7), Mitral bioprosthesis implant (5), Commissurotomy plus Atrioseptoplasty (1), Mitral plasty (1), Pericardium drainage (1); 9) One (5.5%) death in immediate post-operative of the MI correction, 17 (94%) in functional class I/II (NYHA) 14.3 (8-27) months after surgery. CONCLUSION: Age, Sex, VMA G and Urgency character were not discriminative factors in the formation of GI and GII. The procedures for CBVM didn't interfere with post-operative prognosis.

PURPOSE: To study the relationship between symptoms and left ventricular function in 68 patients with severe chronic aortic regurgitation using echocardiogram and radionuclide left ventriculography at rest. METHODS: Three stages of natural history are assumed: the 1st, at the beginning of the study, when all patients were asymptomatic (clinical stage 0); the 2nd, at the end of 36 month persistence of asymptomatic (clinical stage 1), consisting of 45 patients (group AA); the 3rd, on occasion of manifestation of the symptoms during this period of time (clinical stage 2), consisting of 21 patients (group AS-PRE), with two fatalities not related to valvopathy. RESULTS: The comparison between the groups resulted in similarities in the mean ages, mean time of knowledge of the disease, predominance of males and rheumatic etiology. The profile analysis showed that the significant initial differences between the average of all echocardiographic variables (diastolic diameter, systolic diameter, shortening fraction, final systolic stress, volume-mass ratio, contractility index) and of the ejection fraction of the left ventricle obtained by the radionuclide ventriculography at rest, remained during the study. CONCLUSION: Development of symptoms grouped patients with more advanced excentric hypertrophy, did not coincide with any immediate change in the laboratory markers studied at rest and it was used as a referential for surgical therapy.

PURPOSE: To analyze the follow-up of left ventricular function (LVF) after surgical correction of severe chronic aortic insufficiency (AI). METHODS: Twenty-one out of 68 patients with AI, initially asymptomatic and that developed symptoms during the follow-up period of 24-36 months, were studied. Relationship between symptoms and LVF by echocardiogram and radioisotopic ventriculography at rest and in isotonic exercise were studied. Three clinical moments (CM) were assumed: CM-0- at the beginning of the study, when all patients were asymptomatic; CM-1- manifestation of the symptoms during 24-36 months; CM-2- corresponding to the late post-operative period of 8 months of 20 out of 21 patients (one refused the surgery). The analysis did not show any significant differences between the mean values of all echocardiographic variables (diastolic and systolic diameters, shortening fraction, final systolic stress, volume-mass ratio, contractility index) and the ejection fraction of the left ventricle (EF) obtained by the radioisotope ventriculography at rest and, including exercise, between clinical moments 0 and 1. RESULTS: In the CM-2, involution was verified for functional class I/II in all cases and absence of expressive complications or immediate or late postoperative mortality. Comparison between CM-2 and 0 showed expressive regression of the diameters at rest in the postoperative period and with significant improvement in the means mainly the percentual variation of the EF and total time of effort. CONCLUSION: Symptoms assembled patients with more advanced eccentric hypertrophy and did not coincide with any immediate change in findings studied at rest and at exercise. It represented a point of reference for surgical indication compatible with late postoperative involution of chronic adaptation of AI.

PURPOSE: To compare early and 12 months results of mitral stenosis (MS) correction by percutaneous balloon valvuloplasty (PMBV) using Inoue's single-balloon or double balloon techniques. METHODS: We submitted 139 consecutive patients to PMBV using Inoue single-balloon (n = 56, GI) or the double balloon technique (n = 83, GII). The two groups were similar, in: age, sex, functional class (FC), echocardiographic (ECHO) score, mitral valve area (MVA), and gradient (G) or presence of regurgitation. Clinical and ECHO data were compared before (PRE), immediately after (POI) and one year following the procedure (PO12M). RESULTS: PMBV was successfully performed in 53 (95%) patients of GI and in 79 (96%) of GII. Statistical analyses showed that the groups were similar at POI but different at PO12M (p < 0.002). ECHO immediately after PMBV showed that: MVA increased from 0.99 +/- 0.23 to 2.01 +/- 0.44cm2 (p < 0.001) in GI and from 0.94 +/- 0.23 to 2.09 +/- 0.35cm2 (p < 0.001) in GII and G decreased from 11.58 +/- 5.02 to 5.16 +/- 2.23mmHg (p < 0.001) in GI and from 12.48 +/- 4.89 to 5.96 +/- 3.21mmHg (p < 0.001) in GII. After one year 36 (64%) patients in GI and 62 (74%) in GII underwent an ECHO study. A comparison between immediate and one year follow-up results showed that MVA decreased from 2.01 +/- 0.4 to 2.00 +/- 0.3cm2 (NS) in GI and from 2.09 +/- 0.3 to 1.74 +/- 0.4cm2 (p < 0.001) in GII and G decreased from 5.16 +/- 2.2 to 5.50 +/- 2.9mmHg (NS) in GI and from 5.96 +/- 3.2 to 8.61 +/- 4.8mmHg (p < 0.001) in GII. There was therefore a sustained improvement of MVA and G after one year in GI and a significant decrease in MVA and G in GII. The FC after one year was similar and satisfactory in both groups. CONCLUSION: Both techniques are equally effective in relieving MS immediately after PMBV, but after one year, despite similar FC, Inoue-balloon technique seems to be superior to maintain MVA and G.

PURPOSE: To evaluate long-term efficacy of double balloon percutaneous mitral valvuloplasty technique (PMV2B). METHODS: Sixty-eight patients (76% female), mean-age 32 (15-69) years who had been submitted to PMV2B, that completed clinical and echodopplercardiographic one year follow-up (PO12M). Admission criteria were: exertional dyspnoea, no thromboembolism antecedent up to three months before the procedure, absence of other cardiac disease requiring correction, an admissible echodopplercardiographic score, absence of intracavitary thrombus and mitral regurgitation absent or minor. RESULTS: The patients were divided in two groups: group A of 7 (11%) patients that have a cardiac event in this period, and group B of 61 patients that completed the follow-up without a cardiac event. In group A three patients have had a severe mitral regurgitation, one case was unsuccessful and other one had a re-stenosis. There were two deaths, not related to the intervention. In group B, haemodynamic results before and immediately after PMV2B (POI) showed a significant improvement, except in relation to cardiac index. There was an increase in the grade of mitral regurgitation in 17 (28%) patients and in two cases this regurgitation became moderate. The mitral valvar area (MVA) variation between PRE x POI x PO12M presented, comparing MVA between POI and PO12M, a significant reduction. Two (3%) patients with a reduction greater than 50% of the initial increase, 33 (54%) between 10 and 50% and 26 (42%) less that 10% remained in functional class I/II. CONCLUSION: PMV2B is an attractive treatment to select symptomatic mitral stenosis patients, with a low incidence of complications, symptomatic effective improvement that was maintained in one year follow-up, although there was a reduction in MVA.

PURPOSE: To compare immediate and late (12 months) follow-up of clinical and Doppler echocardiographic results between percutaneous mitral balloon valvuloplasty and open commissurotomy in a prospective and randomized trial. METHODS: Eighty eight symptomatic patients with severe mitral stenosis and favorable anatomy were randomized in a prospective trial comparing the two procedures. All patients were submitted to clinical and Doppler echocardiographic evaluation before the procedures and immediate and twelve months thereafter. RESULTS: Mean mitral gradient (mmHg) decreased from 12.2 +/- 5.8 to 5.80 +/- 2.7 (p < 0.001) in commissurotomy group (CG) and from 11.7 +/- 6.1 to 5.0 +/- 2.4 (p < 0.001) in the balloon valvuloplasty group (VG). Mitral valve are (cm2) increased from 0.98 +/- 0.21 to 2.52 +/- 0.46 in CG and from 1.05 +/- 0.25 to 2.18 +/- 0.40 in VG (p < 0.001). In both groups there was a slight decrease in mitral valve area at 12 month follow-up. There was no death in either group. One patient in the VG had moderate mitral regurgitation and underwent surgery. At the 12 month follow-up, all patients in CG and 97.7% of patients in VG were in New York Heart Association functional class I or II. CONCLUSION: Both procedures were safe and showed similar immediate improvement in mitral gradient and functional class. Mitral valve area had a greater increase immediately after commissurotomy, however, there was a significantly greater reduction in the CG after 12 months of follow-up, when compared to balloon valvuloplasty. In both groups, mitral gradient remained reduced and most patients did not change functional class during the follow-up.

PURPOSE: To study characteristics of the natural history of mitral stenosis (MS) in patients that have no correlation between mitral valve areas (MVA) and symptoms. METHODS: We studied 18 patients with MS, that presented no correlation between MVA and functional class (FC), 16 (89%) were female and two (11%) men, with age ranging from 16 to 54 (mean 33) years. Patients assigned to group A (8 cases) had FC III and MVA > or = 1.5 cm2 and group B (10 cases) FC I/II and MVA < 1.1 cm2. FC and MVA at the start (initial time-It) and after 12 months or before surgical correction (SC) or percutaneous mitral balloon valvuloplasty (PBV) (final time-Ft) were compared. All patients with predict O2 uptake (%PRED VO2) at It were evaluated. RESULTS: Five (63%) patients of group A, that maintained MVA > or = 1.5 cm2, changed to FC I/II but three (38%) needed a SC or PBV (2 with lesser MVA at Ft). At group B, six (60%) patients needed SC or PBV. CONCLUSION: MS patients with MVA > or = 1.5 and FC III, providing MVA do not decrease, improves their FC, becoming it more compatible with MVA %PRED VO2. The cases of group B presented the greatest probability of needing SC or PVB.

Hemoglobinopathies are associated with thrombotic complications, when exposed to cardiopulmonary bypass. A 54-year old, black woman with hemoglobinopathy SC and severe mitral stenosis was submitted to eritrocytopheresis 48 hours before mitral commissurotomy surgery. The therapeutic determined appearance of the percentual hemoglobin A of 68% with reduction the hemoglobin S of 48% to 15% and the hemoglobin C of 51% to 17%. No complications occurred during postoperative period. To best of our knowledge, that is the first report about application the eritrocytopheresis in the pre operative extra corporeal circulation care in surgical treatment of patients with chronic rheumatic heart disease and hemoglobinopathy SC.

PURPOSE: To compare immediate and long term results balloon mitral valvuloplasty (BMV) using double balloon or bifoil balloon. METHODS: One hundred and thirteen consecutive cases of BMV used aleatory double balloon (group DB--55 cases) or bifoil balloon (group BF--16 cases). Patients were similar regarding to age, sex, valvopaty etiology, functional class and echocardiographic score. Seventy one (63%) patients achieved 12 months follow-up. RESULTS: In group DB there were 2 (4%) insuccess, 2 (4%) cardiac tamponade and 2 (4%) deaths, 91% patients had immediate criteria of success. Mitral valve area (MVA) increased from 0.8 to 1.69cm2 and mitral gradient (G) by echodopplercardiographic (ECHO) decreased from 17.9 to 4.8mmHg. Three (5%) patients developed severe mitral regurgitation (MR) and needed surgical intervention. At follow-up 2 (4%) developed mitral restenosis. MVA estimated by ECHO study after one year follow-up was inferior to 1.15cm2 in 15 (32%) cases, between 1.5 and 2.0cm2 in 17 (37%) and superior to 2.0cm2 in 14 (31%). In group BF there were 2 (12.5%) insuccess, 4 (25%) developed severe MR occurring 1 death immediate post-operative mitral valve replacement. Among 14 (87%) success cases, MVA increased from 0.8 to 1.89cm2 and G decreased from 18 to 6.4mmHg. Lately 2 (12.5%) needed surgical intervention because significative MR. At 12th month follow-up the ECHO study showed that in one (10%) case MVA was < 1.5cm2, and in 3 (27%) cases was between 1.5 and 2.0cm2. CONCLUSION: There were similar good results in both groups, however group DB had more restenosis, cardiac tamponade and vascular complications and group BF had more severe MR.

We studied five patients with acquired ventricular septal defect during the course of an infective endocarditis. All patients were male and had a previous aortic valve disease associated with an aortic ring abscess. Clinical examination was useful for the diagnosis of 4 cases, emphasizing the following findings: systolic murmur and/or left paraesternal thrill and right-heart failure. Incidence of congestive heart failure was 60%, while 40% of all patients died during the in-hospital course. No specific etiologic agent was detected. Therefore, acquired ventricular septal defect should be suspected in patients with infective endocarditis of the aortic valve that evolve with a systolic murmur and/or paraesternal thrill and right-heart failure. Immediate surgical treatment is mandatory in these cases.

A 52 year-old man, with rheumatic cardiopathy and hemophilia was admitted to the hospital for aortic valve replacement and mitral valve commisurotomy. He had a history of allergic reaction to cryoprecipitate, and to undergo to the cardiac surgery, the ideal level of factor VIII was estimated to be 100%. To reach this level he first received 2,500UI of the factor VIII:C increasing the factor VIII:C level from 20 to 58%. During the surgery he received an additional dose of 1,500UI of factor VIII plus 3,500,000UI of aprotinin (Trasylol), which was started at the beginning of the anaesthesia and maintained during the surgical procedure, increasing the factor VIII level to 220%. The patient was discharged 11 days after the surgery without any hemorrhagic complication.
