The results of histological, histochemical and electron microscopic study of the muscular involvement in eight patients with Ankylosing Spondylitis (AS) are described. Muscle tissue from all these patients showed gross abnormalities of the sacrospinalis muscle, which had a 'targetoid core' appearance common to several myopathic and neurological diseases. In our opinion, there is always constant and early involvement of this muscle in AS. Several factors associated with the disease (chronic inflammation, multiple enthesopathies, muscle stiffness and bone lesions) could be responsible for this not fully understood aspect of AS. They may lead to a non specific damage of the nervous and/or muscular components of the spine in these patients.

Detection and morphology of thymic remnants after video-assisted thoracoscopic extended thymectomy (VATET) in patients with myasthenia gravis.

Thymectomy is often an extremely useful therapeutic procedure in myasthenia gravis (MG) and is usually indicated for adult patients with generalized disease. Because remnants of thymus may remain in extrathymic fat, an extended thymectomy is recommended. A new surgical approach without sternotomy: video-assisted thoracoscopic extended thymectomy (VATET) was performed in 30 MG patients. The weight of removed thymus ranged from 10.8 to 113 grams. The weight of fatty tissue removed from pretracheal, anterior mediastinal and costophrenic areas ranged from 6.3 to 74.8 grams. Histological examination revealed thymic remnants in 14.8% of pretracheal fat samples and in 33.3% of samples from anterior mediastinal plus costophrenic areas. These findings indicate that VATET is a radical procedure and may be the first choice surgery for young female MG patients, since aesthetic sequelae are reduced compared to procedures involving sternotomy.
