ABSTRACT

O osteocondroma é um tumor ósseo benigno extremamente comum. Este tipo de tumor pode ocorrer em qualquer osso, principalmente em fêmur distal e tíbia proximal. Porém, a sua ocorrência no colo femoral é extremamente rara, com poucos casos relatados na literatura. O objetivo deste trabalho é apresentar o caso de um paciente diagnosticado com osteocondroma em região posterior do colo do femoral. Embora a ocorrência dos osteocondromas na região posterior do colo femoral seja extremamente rara, estes devem ser considerados no diagnóstico diferencial de massas nessa região.


Osteochondroma is an extremely common benign bone tumor. This type of tumor can occur in any bone, particularly in the distal femur and proximal tibia. However, its occurrence in the femoral neck is extremely rare, with few cases reported in the literature. The aim of this paper is to present the case of a patient diagnosed with osteochondroma in the posterior femoral neck. Although the occurrence of osteochondromas in the posterior region of the femoral neck is extremely rare, this should be considered in the differential diagnosis of masses in this region.

ABSTRACT

A medula espinhal é a parte do Sistema Nervoso Central envolta pela coluna vertebral. Neoplasias primárias ou metastáticas podem causar compressão medular e acarretar quadros clínicos característicos de acordo com os tratos espinhais afetados. A anamnese e o exame físico são de suma importância para abordagem inicial.


The spinal cord is a part of the central nervous system protected by the vertebrae spine. Primary or metastatic neoplasm tumors could cause spinal compression resulting in characteristic clinical manifestations due to a specific spinal tract involved. History and physical exam have a role part as a first step approach in these patients.

ABSTRACT

OBJECTIVES: The aim of this study was to test the hypothesis that experimental maternal intake of green tea in late pregnancy causes fetal ductus arteriosus constriction, probably because of prostaglandin inhibition. METHODS AND RESULTS: Twelve fetal lambs (pregnancy > 120 days) were assessed before and after maternal administration of green tea (n = 8) or water (n = 4; controls) as the only source of liquid. After 1 week, echocardiography showed signs of constriction of the ductus arteriosus in all fetuses from mothers ingesting green tea, with increase in mean systolic velocity(from 0.70 ± 0.19 m/s to 0.92 ± 0.15 m/s, 31.4%, p = 0.001) and mean diastolic velocity (0.19 ± 0.05 m/s to 0.31 ± 0.01 m/s, 63.1%, p < 0.001), decrease of pulsatility index (2.2 ± 0.4 to 1.8 ± 0.3, 22.2%, p = 0.003) and increase of mean right ventricular/left ventricular diameter ratio (0.89 ± 0.14 to 1.43 ± 0.23, 60.6%, p < 0.001). In the four control fetuses, there were no significant changes. All lambs exposed to green tea also showed at autopsy dilated and hypertrophic right ventricles, which was not present in control fetuses. Histological analysis showed a significantly larger mean thickness of the medial avascular zone of the ductus arteriosus in fetuses exposed to green tea than in controls (747.6 ± 214.6 µm vs 255.3 ± 97.9 µm, p < 0.001). CONCLUSIONS: This study in fetal lambs shows a cause and effect relationship between experimental maternal exposure of green tea and fetal ductus arteriosus constriction in late pregnancy.
