RESUMEN

Soft tissue tumors, involving the vascular bundle, require a particular surgical approach: oncological and vascular surgical techniques must be integrated in order to perform a limb-saving surgery with adequate margins. Thirty-six soft tissue sarcomas of the thigh and popliteal region were treated from June 1999 to September 2002. Nineteen cases involving the vascular bundle were analysed and placed in two groups according to imaging and clinical information: Group A, 14 patients, with tumors close to femoral vessels without adventitial infiltration, and Group B, 5 patients, with vascular infiltration. Group A was treated with vascular blunt dissection performing adventitial excision. Group B was treated with vascular "en-bloc" resection and reconstruction. Imaging and clinical information together with surgical techniques, strategies and complications were analysed in order to plan the surgical approach in neoplastic vascular bundle involvement.

RESUMEN

PURPOSE: Echocolor Power Doppler with contrast medium forms a non-invasive vascular image; the purpose of the study is to evaluate the effectiveness in differentiating benign and malignant tumors in the soft tissues of the limbs. MATERIAL AND METHOD: Echocolor Power Doppler with contrast medium was used to study 80 patients with swelling in the soft tissues of the limbs: there were 54 benign lesions, 22 sarcomas, and 4 aggressive desmoid fibromatoses. RESULTS: Were identified 4 patterns of wash-in and wash-out curves that could be correlated to the histological diagnosis: type I was present in 85% of benign lesions, type III in 91% of malignant lesions and in 3.7% of the benign ones, type II in aggressive fibromatoses, anomalous type in 4 benign lesions and 2 sarcomas; the curve was absent in 2 benign lesions. CONCLUSIONS: Power Doppler Echocolor with contrast medium can become a useful method to be associated with traditional imaging methods in the differential diagnosis of swelling of the soft tissues of the limbs.

RESUMEN

PURPOSE: Evaluation of bone remanagement after treatment by thermoablation of osteoid osteoma (OO) by CT scan. MATERIAL AND METHOD: Nine cases of OO (8 in the limbs, 1 in the pelvis) following biopsy were treated by CT-guided thermoablation. Clinical results, complications, density of tissues treated by CT scan (pre-postop, 6, 12 months) are evaluated. RESULTS: Absence of complications, regression of pain over 2 weeks, resumption of sports activity in 1 month. Bone density after treatment increases but even after 1 year it is much lower than normal levels. CONCLUSIONS: Bone remodeling after thermoablation of OO requires much time, the process is still visible 12 months later by CT scan. CT scan is an adequate method, not only for diagnosis and treatment, but also for follow-up, capable of evaluating in time the changes in density of the site of the lesion, which is useful for a comparison in case of postoperative pain of doubtful origin.

RESUMEN

The aim of this study was to analyze the morphological cochlear changes and auditory function observed after the administration of estrogen or progesterone or both. Sixty-two guinea pigs were divided into four groups that received estrogen (group 1), progesterone (group 2), estrogen and progesterone (group 3), and saline solution (controls, group 4), respectively. The auditory evaluation consisted of brainstem evoked response audiometry, performed before and after drug administration. Structural analysis was based on histological hematoxylin and eosin staining preparations. Our results showed changes in latency and amplitude of waves in the study groups that received estrogen or progesterone. The main histological changes observed were inflammatory infiltrate and vacuolization of the stria vascularis. Our results suggest that both estrogen and progesterone lead to morphological and physiological lesions of the cochlea, the degree of the observed lesions depending not only on the presence of these hormones but also on the proportion between them.

RESUMEN

INTRODUCTION: Young's syndrome is part of primary ciliary dyskinesia, characterized by repeated airway infections and congenital epididymis obstruction. CASE REPORT: The authors present the case of a 28-year old male with recurrent rhinosinusitis and pneumonia. Sweat and immunologic tests fell within the normal range. Sperm analyses revealed absence of spermatozoa although spermatogenesis was normal according to the findings in testis biopsy. DISCUSSION: The final diagnosis was Young's syndrome the first case of the disease reported in Brazilian literature. CONCLUSIONS: The authors emphasize the need for appropriate diagnosis and genetic counselling as well as differential diagnosis with cystic fibrosis in these cases.

RESUMEN

INTRODUÇÃO: A síndrome de Young é uma variante da discinesia ciliar primária, caracterizada pela ocorrência de infecções respiratórias de repetição e obstrução congênita do epidídimo. APRESENTAÇÃO DO CASO: Os autores apresentam um caso de rinossinusite e pneumonias de repetição em um paciente de 28 anos do sexo masculino. Dosagem de sódio e cloro no suor e pesquisa de imunodeficiências celulares e humorais resultaram negativas. O espermograma revelou azoospermia, embora a espermatogênese estivesse mantida, conforme achado na biópsia de testículo. DISCUSSÃO: O diagnóstico foi de síndrome de Young, sendo este o primeiro caso relatado no Brasil. CONCLUSÃO: Os autores alertam para a importância desse diagnóstico, dadas suas implicações para aconselhamento genético, além do diagnóstico diferencial a ser feito com a fibrose cística.

RESUMEN

Os autores fazem a revisäo bibliográfica e apresentam um caso de Lipoidoproteinose, ou hialinose cutâneo-mucosa ou Doença de Urbach-Wiethe. Trata-se de uma doença rara, que ocorre por acumulo de material hialino de natureza bioquímica desconhecida, nas mucosas, pele, trato aéreo digestivo alto, sistema nervoso central, e em outros tecidos. Säo descritos as manifestaçöes e os achados clínicos gerais e otorrinolaringológicos, os exames complementares, bem como a evoluçäo clínica. Pela raridade e gravidade da doença que näo tende a regredir seja espontaneamente ou com tratamento, levando ao êxito letal, o otorrinolaringologista deve ter conhecimento prévio desta doença

RESUMEN

La profundidad de las criptas endocervicales fue determinada en 83 conos cervicales con un promedio de 60 cortes por cono. La profundidad media de las criptas indemmes fue de 5.08 + ou - 1.56 mms. con una profundidad maxima de 10.35 mms. Tambien fueron medidas las criptas que presentaban lesiones atipicas en su interior, las que teniam una profundidad media de 3.14 + ou - 2.47 mms. siendo 1 a mas profunda de 8.63 mms. El canal endocervical presento en el 53,7% lesiones atipicas, pero solamente el 4,8% del total de casos mostro compromiso del tercio superior del mismo
