Abstract: objective: to confirm the validity of the calculation in mva applying the method of doppler pressure half-time directly in left atrial (la) and pulmonary capillary pressure curve. methods: thirty-five patients with mitral valve stenosis underwent percutaneous mitral valvotomy (pmv) using the cribier method with mva measurement made using the traditional methods (gorlin and echo-doppler) and this propose. mva values obtained were compared and a linear regression model was used to obtain formula for reciprocal calculations of the mitral valve area. results: a statistically correlation was found between the calculated values by all methods. the proposed method showed a strong correlation (p< 0.05) with the others mainly before valve opening. simple reciprocal calculation formulas were found for mitral valve area assessment. conclusion: the proposed method for the calculation of mitral valve area using la or cap proved to be highly accurate and simple making it possible to safely monitor valvotomy procedures.

Abstract: objective: to analyze the efficacy of percutaneous transluminal septal alcoholization in the treatment of refractory obstructive hypertrophic cardiomyopathy (hoc). methods: the patients were referred for alcoholization after doppler echocardiography. before and after alcoholization, the intraventricular pressure gradient was recorded. alcoholization was performed with a 3ml injection of absolute alcohol through a coronary angioplasty balloon catheter. the procedure was concluded after a significant reduction or abolition of the pressure gradient. results: of 22 patients, 18 (81.8%) successfully concluded the procedure with a reduction in intraventricular pressure gradient at baseline (from 67.6±24.2 mmhg to 3.8± 1.9 mmhg, p<0.005) and after extrasystole (from 110.4± 24.2 mmhg to 9.6±2.6 mm hg, p<0.005). a significant reduction in mean interventricular septal thickness (from 2± 0.3 mm to 1.7±0.2 mm, p<0.005) and in peak pressure gradient (from 90.7±23.5 mmhg to 6.1±1.4 mmhg, p<0.005) was observed on doppler echocardiography after 6 months, when all patients were in functional class i. the most frequent acute complication, present in 11% of the patients, was the need for definitive pacing implantation. relapse of the symptoms and reappearance of the pressure gradient occurred in 16.6% of the patients. one patient (5.5%) died probably due to a diffuse coronary spasm prior to the procedure, and another died suddenly on late follow-up. conclusion: percutaneous transluminal septal alcoholization is effective and safe in the treatment of hoc.

Abstract: exposure to noise has a harmful effect on the auditory health of workers. aim: the main goal of this paper was to establish the role of pure-tone audiometry and evoked transient otoacoustic emissions in the detection of small temporary auditory changes after exposure to high sound pressure levels. study design: a cross-sectional cohort study. material and methods: 30 otologically normal subjects aged between 20 and 35 years were submitted to pure-tone audiometry and evoked transiente otoacoustic emissions before and after 5 hours of exposure to high sound pressure levels (betweeen 80 and 90 db). results: for pure-tone audiometry the largest changes occurred at high frequencies - from 3 khz to 8 khz after exposure. the evoked transient otoacoustic emissions showed reduced reproductibility from 1 khz to 4 khz after exposure to noise. conclusion: we noted that both pure-tone audiometry and evoked transient otoacoustic emissions had a role in detecting statistically significant changes in the auditory threshold and in reproductibility, after exposure to high sound pressure levels.

Abstract: this article deals with the controversies and contradictions that have followed the discussions about the scientific character in the field of social sciences and its paradigmatic controversies in order to think about the social reality. it supports the idea of the becoming, the historicity and the ideological nature of the process of knowledge, as well as the absence of a single scientific method. it emphasizes the relationship between subject and object in the process of objectification of knowledge and the link with the empirical, having in mind that objectivity is the utopia of science. finally, it stresses the requirements of the scientific method in relation to the constitution of flexible and rigorous methods that consider the dynamics and the temporary character of the material and symbolic reality.

Revista médica de Chile , 2009,
Abstract: Prader- Willi syndrome is an uncommon multisystem genetic disorder caused by defects of chromosome 15 (15qll-ql3), often due to deletions or uniparental disomy The syndrome is characterized by neonatal hypotonia, dysmorphic facial features, short stature, motor and mental disabilities, behavioral changes, hyperphagia, precocious obesity and hypogonadotropic hypogonadism. We present a 17year-old woman, with a previous genetic diagnosis of Prader-Willi syndrome and BMI of 74 Kg/m2, that was admitted in anasarca, with marked cyanosis, dyspnea and oliguria. She presented high levels ofblood urea, creatinine and aminotransferases, in addition to hyperkalemia and hyperuricemia. She had been in regular use of fluoxetine during the last six months, and evolved with severe high bloodpressure and respiratory failure, which needed intensive care support. Moreover, sequéis and clear signs of recent selfinjuries were observed in her trunk, forearms and hands. The findings of morbid obesity, anasarca, self-injury, hyperuricemia and hypoxemia in Prader- Willi syndrome are emphasized. El síndrome de Prader-Willi es un desorden multisistémico infrecuente causado por defectos genéticos del cromosoma 15 (15qll-ql3), debido a deleciones o disomía uniparental. Se caracteriza por hipotonía neonatal, dismorfias faciales, baja estatura, incapacidades motoras y mentales, problemas conductuales, hiperfagia, obesidad precoz e hipogonadismo hipogonadotrófico. Presentamos una mujer de 17 a os, con IMC de 74 Kg/m2 con diagnóstico genético previo del síndrome que ingresó con anasarca, intensa cianosis, disnea y oliguria. Presentaba elevación plasmática de urea, creatinina y aminotransferasas, asociadas con hiperkalemia e hiperuricemia. Había utilizado regularmente uoxetina durante los seis meses precedentes y evolucionó con hipertensión arterial severa e insuficiencia respiratoria, que requirieron de cuidados intensivos. Además, se constataron cicatrices y claras se ales de automutilación reciente en su tronco, antebrazos y manos. Se destacan los hallazgos de obesidad mórbida, anasarca, automutilación, hiperuricemia e hipoxemia en el síndrome de Prader-Willi.

Abstract: O presente artigo aborda as polêmicas e contradi es que têm acompanhado as discuss es acerca da cientificidade no campo das Ciências Sociais e suas controvérsias paradigmáticas no intuito de pensar a realidade social. Advoga a ideia do devir, a historicidade e o caráter ideológico do processo de conhecimento, além da inexistência de um único método científico. Destaca a rela o sujeito e objeto no processo de objetiva o do conhecimento e do vínculo com o empírico, sem esquecer que a objetividade é a utopia da ciência. Por fim, enfatiza as exigências do método científico, na condi o de constitui o de métodos rigorosos e flexíveis que consideram a dinamica e a provisoriedade da realidade material e simbólica.

Abstract: Liver and lung metastasis and local lymph node invasion are reported in a 26-year-old Brazilian woman with an asymptomatic colon cancer. She was admitted complaining of right upper quadrant pain, and the diagnostic procedures revealed an unsuspected adenocarcinoma (stage IV) in the descending colon. This malignancy is more frequent in patients older than 40 years, but it usually follows a more aggressive course in young people. Late detection of colon cancer usually results in worst prognosis Se presenta un caso en que se demuestran metástasis de un cáncer del colon asintomático en hígado y pulmones, además de invasión ocal de infonodos en una mujer brasile a de 26 a os de edad. Al ingresar al hospital, la paciente se quejaba de dolor en hipocondrio derecho. Los procedimientos diagnósticos revelaron un adenocarcinoma no sospechado (fase IV) en el colon descendente. Esta malignidad es más frecuente en os pacientes mayores de 40 a os, pero suele tener un curso más agresivo en personas jóvenes. La detección tardía del cáncer del colon habitualmente condiciona un peor pronóstico
