Saraiva,Luís Eduardo; Joana,Pierre-Michel;
Rela??es Internacionais (R:I) , 2011,
Abstract: in this article we argue that the normalization of the somali situation with the return of the rule of law depends of the conditions created to the development aid and of the rule of law structures’ reconstruction. this struggles will also led to bring security in the horn of africa and indic. for that purpose it will be necessary to provide resources to entities and organizations, such as the african union, as well as to the somali political structures which have the political and strategic conditions to achieve it.

Abstract: Este artigo argumenta que a normaliza o da situa o da Somália, e o estabelecimento do Estado de direito, dependem da cria o de condi es para ajuda ao desenvolvimento e dos esfor os na reconstru o das estruturas necessárias ao Estado de Direito. Tais esfor os conduzir o simultaneamente para solucionar a inseguran a no Corno de áfrica e no índico. Para tal, há que proporcionar recursos às entidades e organiza es, como a Uni o Africana, e às estruturas políticas da Somália, que n o só têm a vontade para o fazer, como têm também as melhores condi es políticas e estratégicas para serem bem-sucedidas.

Abstract: introduction: multiple sclerosis (ms) is a primary demyelinating disease of autoimmune ethiology with different immunopathologic mechanisms. anti-myelin autoantibodies may be associated with myelin damage and a possible marker of the disease evolution. however, the clinical usefulness of these autoantibodies is questionable as they may be present in healthy individuals. the aim of this work was the evaluation of autoantibodies against myelin in patients with ms comparatively with control samples, and their association with differents clinical types. methology: for the search of anti-myelin antibodies we used indirect immunofluorescence in primate peripheral nerves (euroimmun?). thirty four patients (14 female/11 male) followed in the neurology department were studied: 8 with the clinically isolated syndrome (cis) with relapse, 11 with relapsing/remitting (rr) in remission, 11 with rr with relapse and 4 with primary progressive (pp); 25 samples of healthy individuals (26 female/8 male) were studied as controls. results: the presence of autoantibodies to myelin was signifiantly different in the two studied populations (p<0.001). within the different clinical types we found a prevalence of 87.5% in cis, 77.3% in rr and 75.0% in the patients with pp. most patients (94.7%) in relapse had antibodies against myelin versus 60.0% of those in remision. in the control group, 32.0% presented anti-myelin antibodies. conclusions: although this test was not specific for ms, in the patient population studied the presence of anti-myelin antibodies by indirect immunofluorescence was higher in those in relapse. until new and better serologic markers are available, this test may be useful to monitor patients with possible or definitive diagnosis of ms, in witch the presence of anti-myelin antibodies may support a possible relapse.
Regularity of subschemes invariant under Pfaff fields on projective spaces

Mathematics , 2009,
Abstract: A Pfaff field on a projective space is a map from the sheaf of differential s-forms, for a certain s, to an invertible sheaf. The interesting ones are those arising from a Pfaff system, as they give rise to a distribution away from their singular locus. A subscheme of the projective space is said to be invariant under the Pfaff field, if the latter induces a Pfaff field on the subscheme. We give bounds for the Castelnuovo-Mumford regularity of invariant complete intersection subschemes (more generally, arithmetically Cohen-Macaulay subschemes) of dimension s, depending on how singular these schemes are, thus bounding the degrees of the hypersurfaces that cut them out.

Abstract: introduction: while the rate of smoking and lung cancer mortality has been decreasing in western europe, there was no decline in lung cancer mortality in portugal until 1998. aim: to describe lung cancer mortality trends in portugal. methods: lung cancer mortality rates (international disease classification 10: c33-34) in portugal 1955-2005 by gender and 5-year age groupings were provided by the world health organization and the national institute of statistics. standard mortality rates (direct method, world population) were calculated for the 35-74, 35-44, 45-54, 55-64 and 65-74 year-old age groups. joinpoint regression was used to calculate the annual percent change (apc) in mortality and to identify any inflection points. results: between 1955 and 2005 we observed a stabilisation in lung cancer mortality in men aged 35-74 years old, varying 3.77%/year (95% confidence interval [95%ci]: 3.53-4.01) in 1955-1986 and -0.15%/year (95%ci: -0.99-0.69) in 1996-2005. we observed negative apc point estimates (with none significantly below zero) in the most recent trends except for the 45-54 age group, where we only noted an apc deceleration since 1981. the mortality increased 1.60%/year (95%ci: 1.40-1.77) in women aged 35-74 years old 1955-2005. conclusion: in the last two decades we observed a lung cancer mortality stabilisation in males, whereas mortality in females increased continuously. these results place portugal at the end of the third stage of the smoking epidemic.

Abstract: studies indicate that in brazil blacks have less formal education, lower salaries, reside in peripheral neighborhoods in large urban centers and are excluded from various social rights. this study is based on the hypothesis that health, sickness, and death are socially constructed processes demarcated by the social space occupied in society by men and women, blacks and whites. this article analyses the mortality profile of black and white men as registered in the death certificates emitted by the state of s?o paulo in the year 1999. rates of mortality were analyzed according to basic causes, according to the groups of icd-10 [the international statistical classification of diseases and related health problems], and to the race/color: black and white. this study indicates that when rates of mortality of black and white men are compared, mental illnesses (alcoholism and drug addiction); infectious and parasitic diseases (tuberculoses and hiv/aids) as well as external causes (homicides) are more frequent causes of death among black men.

Prenatal Diagnosis of a Congenital Postaxial Longitudinal Limb Defect: A Case Report
Joana Pauleta,Maria Antonieta Melo,Luís Mendes Gra?a
Obstetrics and Gynecology International , 2010, DOI: 10.1155/2010/825639
Abstract: Introduction. Although congenital longitudinal fibular deficiency is one of the most common long bone deficiencies, there are few published cases of its prenatal diagnosis. Case report. A right longitudinal deficiency of the fibula associated with tibial shortening, foot equinovalgus, and absence of the fourth and fifth foot rays diagnosed at 22 weeks gestation is described. Sequential ultrasonographic surveillance was performed without obstetric complications. The anomaly was confirmed after birth, and conservative orthopaedic management was decided. Conclusion. Though rarely seen, postaxial longitudinal limb defect may be detected by ultrasound. The correct approach can only be decided after birth, when the functional impact of the anomaly can be fully evaluated. 1. Introduction Postaxial longitudinal defect is one of the most common congenital limb reduction defects. This entity includes a large spectrum of abnormalities that may range from severe hypoplasia to complete absence of the fibula and the 5th rays. It is a rare disorder, with an estimated prevalence of 5.7 to 20 cases per 1 million births [1]. Up to now, only few cases of prenatal diagnosis of isolated longitudinal deficiency of the fibula were reported [1–4]. 2. Case Report A 38-year-old healthy primigravida, with no familiar history of limb defects or exposure to teratogenic drugs, was referred to our ultrasound unit at 22 weeks gestation after the absence of the right fibula was diagnosed during the second trimester ultrasound examination. This diagnosis was confirmed in our department. Further assessment of the ipsilateral lower limb detected a discrete femur shortening (35?mm versus 37?mm of left femur, discrepancy of 5.4%), anteromedial bowing and tibial shortening (27.2?mm versus 33.6?mm of left tibia, discrepancy of 19%), see Figure 1, foot equinovalgus, and absence of the fourth and fifth foot rays and digits. All other long bones (humeri, ulnae, and radii) were symmetric and appropriated in length and configuration for gestational age, as were the hands. No other anomalies were detected, namely, craniosynostosis, omphalocele, renal displasia, neural tube defects, thoracoabdominal schisis, or facial dysmorphies. Amniocentesis revealed a normal female karyotype (46, XX). Fetal echocardiography was normal. Follow-up ultrasound examinations were carried out periodically until birth (Figure 2). Tibial discrepancy increased slightly with a difference of 13?mm (23.6%) at 34 weeks gestation. Figure 1: Ultrasound images showing absence of right fibula, bowing of right tibia (a), and
Should C-reactive protein concentration at ICU discharge be used as a prognostic marker?

Abstract: The aim of our study was to determine the ability of the clinical and inflammatory markers at ICU discharge to predict post-ICU mortality.A prospective observational cohort study was conducted during a 14-month period in an 8 bed polyvalent ICU. Acute Physiology and Chronic Health Evaluation (APACHE) II score, Simplified Acute Physiology Score (SAPS) II, Sequential Organ Failure Assessment (SOFA) score, Therapeutic Intervention Scoring System-28 (TISS-28), C-reactive protein (CRP), white cell count (WCC) and body temperature of the day of ICU discharge were collected from patients who survived their first ICU admission.During this period 156 patients were discharged alive from the ICU. A total of 29 patients (18.6%) died after ICU discharge. There were no differences in clinical and demographic characteristics between survivors and nonsurvivors. C-reactive protein levels at ICU discharge were not significantly different between survivors and nonsurvivors. The area under receiver operating characteristics curves of APACHE II, SAPS II, SOFA, TISS-28, CRP, WCC and body temperature at ICU discharge as prognostic markers of hospital death were 0.76 (95% confidence interval (CI) 0.67-0.86); 0.75 (95% CI 0.66-0.85); 0.72 (95% CI 0.62-0.83); 0.64 (95% CI 0.52-0.77); 0.55 (95% CI 0.43-0.67); 0.55 (95% CI 0.42-0.66) and 0.54 (95% CI 0.44-0.67) respectively. The hospital mortality rate of the patients with CRP <5, 5-10, >10 mg/dL was 15.1%, 16.1% and 33.3% respectively (p = NS).At ICU discharge serum CRP concentration was a poor marker of post-ICU prognosis. Post-ICU death appears to be unrelated to the persistent inflammatory response.Critically ill patients are responsible for 10-25% global hospital costs [1]. The ability to identify critically ill patients who will not survive until hospital discharge may allow identification of high risk patients leading to more conservative strategies of ICU discharge.About one third of hospital mortality of critically ill patients occurs
