Prevalência da doença arterial obstrutiva periférica em doentes com insuficiência renal crônica

Background: Peripheral occlusive arterial disease has been found to be a sensitive marker of systemic atherosclerosis and a predictor of other cardiovascular diseases. In spite of the high prevalence of the cardiovascular diseases, there are few studies about peripheral occlusive arterial disease in patients with chronic renal failure under hemodialysis treatment. Objective: To determine the prevalence of peripheral occlusive arterial disease in patients with chronic renal failure under hemodialysis treatment at a center of excellence in the State of Sergipe, Brazil. Methods: A cross-sectional study was conducted from June to November 2008 at a center of excellence for the treatment of patients with chronic renal failure. Those patients with the ankle-brachial index (ABI) ≤ 0.9 were diagnosed as having peripheral occlusive arterial disease. Results: From a population of 239 individuals with chronic renal failure, 201 were evaluated. Of that, 28 (14%) had peripheral arterial insufficiency with ABI ≤ 0.9. Their age ranged from 24 to 82 years (mean age = 52 years). Hypertension and dyslipidemia were the more frequent risk factors. Among the patients with peripheral occlusive arterial disease, 89% had dyslipidemia; 71% had high blood pressure; and 29% had coronary diseases. Conclusion: The prevalence of peripheral occlusive arterial disease in patients with chronic renal failure was 14%.

The availability of teaching–pedagogical resources used for promotion of learning in teaching human anatomy

Five hundred students attending higher education institutions in northeastern Brazil responded to questionnaires about their anatomy classes; students represented a variety of different health sciences disciplines. Analysis of the responses revealed the participation of teaching assistants in a large percentage of classes and the use of teaching resources, particularly images, from conventional radiographs to magnetic resonance images. The number of classes for cadaver dissection and the number of students with access to that type of class were small. In most cases, dissection was performed according to anatomic regions or systems. Medicine and nursing students had the highest number of practical dissection classes. Most students were assessed using practical and theoretical tests. Findings revealed conditions similar to those found elsewhere. Resources should be renewed and used to improve teaching for students whose courses demand the study of human anatomy.

O PERFIL EPIDEMIOLÓGICO DOS PACIENTES COM CARDIOPATIAS CONGÊNITAS SUBMETIDOS À CIRURGIA NO HOSPITAL DO CORAÇÃO

Objective: To outline the epidemiological profile of patients with congenital heart disease undergoing surgery in the heart hospital. Material and Methods: We conducted a cross-sectional, descriptive and exploratory study, with quantitative analysis from medical records of patients less than 18 years of age with congenital heart disease, treated between August 1st 2005 to July 31st 2010. Results: Of the 300 patients with operated congenital heart disease during that period, 69.7% (209) were of acyanotic type; of these, the most frequent type was the ventricular septal defect accounting for 21% (63) of the cases. Among the cyanotic heart defects, tetralogy of Fallot was found in 14% (42) of the patients. The cyanotic and acyanotic defects evolved to death in 82.7% (24) and 17.3% (5) of the cases, respectively. Conclusion: The findings indicated that the profile of patients with congenital heart disease was composed by infants, preschoolers and schoolchildren, without gender dominance. There was a predominance of acyanotic congenital heart defects, and most deaths were related to cyanotic heart diseases.

Implementação financeira e o impacto do mutirão de cirurgias de varizes, após a criação do Fundo de Ações Estratégias e Compensação (FAEC)

BACKGROUND: In spite of the fact that the number of surgeries presented by the elective surgery task force did not entirely reflect the reality, it is possible to declare that the financial implementation of the Brazilian Ministry of Health has been significative, as well as the increasing number of varicose vein surgeries, especially after the creation of the Strategic Actions and Compensation Fund (FAEC). OBJECTIVE: To evaluate the application of financial investment in the Ministry of Health campaign for varicose vein surgery. METHODS: A transversal study of retrospective nature has been conducted, using information available at the Data Processing Department of the National Healthcare System database (DATASUS). All the authorization of hospital internment from the inferior member varicose vein surgeries, financed by the Brazilian Ministry of Health from January 1998 to December 2004, have been included in the research. RESULTS: In 1998, before the implementation of the elective surgery task force, 23,531 varicose vein surgeries have been performed, and R

CONCLUSION: Thus, it is possible to conclude that the bigger investment from the Brazilian Ministry of Health, represented by the implementation of the elective surgery task forces by the FAEC, has been responsible for increasing the number of varicose vein surgeries all around Brazil.

Morphological Types of Foramen Magnum

Introduction: The median nerve is one of the most important terminal branches of the brachial plexus. Anatomical variations in the formation of the median nerve are common and have been reported by several authors. Objective: The aim of this study was to analyze the anatomical variations of the median nerve in cadavers of human fetuses, from its origin to the formation of the median nerve. Materials and Methods: Twenty-five fixed human fetuses (50 upper limbs) were dissected by planes with conventional technique and classic instrumentation. Results: The frequency of variation in formation of the median nerve was 28%. The more frequent anatomical variations were: a communicant branch between the median and the

The superior transverse scapular ligament in fetuses.

Objective: To report the finding of double bilateral renal artery case in human fetus. Case Report: Duplicity of the renal artery was found in a male fetus. The right kidney received two renal arteries, one superior, measuring 6,68 mm, and other inferior with 5,85 mm, both steered parallel and bifurcated before penetrating the renal hilum. Likewise, the left kidney received two renal arteries, one superior, measuring 4,16 mm and other left with 9,93 mm, the superior being the only one that bifurcarted itself before penetrating the renal hilum. Conclusion: The current finding of accessory renal arteries represents collaboration not just for anatomists, but also with considerable significance to urological surgeons.
