Association of distinct intracranial pial and dural arteriovenous shunts.

Intracranial pial and dural arteriovenous shunts may exist at different sites in the same patient. The etiology, natural history and treatment of these associated conditions have not been completely determined. We reviewed the records of 765 cases of pial arteriovenous malformation and 137 dural arteriovenous fistulae and malformations.

Acute type A aortic dissection involving the left main coronary artery and the aortic valve--a case report.

The authors report a case study of a 60 year-old-male admitted to the Coronary Care Unit with severe chest pain, hypertension and ST depression on the anterior and lateral leads of the electrocardiogram. A diastolic murmur was heard in the aortic area. The chest X-ray showed an enlarged superior mediastinum.

Treatment of intracranial venous occlusive disease with sigmoid sinus angioplasty and stent placement in a case of infantile multifocal dural arteriovenous shunts.

The infantile dural arteriovenous shunts are multifocal involving different dural sinuses and progress to an occlusive venopathy with sigmoid sinus and/or jugular bulb stenosis and subsequent occlusion. We report a successful angioplasty and stent placement of a sigmoid sinus - jugular bulb stenosis due to venous occlusive disease in a patient with infantile dural arteriovenous shunts. A five-year-old patient presented with status epilepticus due to severe venous congestive encephalopathy.

Brooke-Spiegler syndrome: treatment of cylindromas with CO2 laser.

Brooke-Spiegler syndrome is an autosomal dominant inherited disease characterized by the development of multiple trichoepitheliomas and cylindromas. We report two patients with Brooke-Spiegler syndrome whose scalp cylindromas were treated with a high-energy continous wave CO2 laser after debulking with bipolar scissors in one of the patients. The special feature in our report is the coexistence of three adnexal skin neoplasms in one case, and the close association of cylindroma and eccrine spiradenoma in the same lesion.

Cardiac rupture during exercise stress echocardiography: a case report.

Stress echocardiography is widely used in the evaluation of coronary artery disease. Dobutamine stress echocardiography has been the preferred method, but many centers have adopted exercise stress echocardiography, which can visualize myocardial motion during physiologic stress testing. The complications of this method in the post-myocardial infarction period are the same as those identified in conventional exercise testing.

Second primitive malignant tumour in patients with gynaecological cancer.

Objective: The purpose of this study was to characterise the occurrence of multiple primitive gynaecological malignant neoplasias, restricted to the genital tract and breast or associated with other organs, and to detect which types of association are most frequent concerning location, histology and staging.

Population And Methods: The records of patients with gynaecological cancer at the Portuguese Institute of Oncology--Lisbon Centre, between 1986 and 1993 were used in this study.

Results: Of the 10,746 women with gynaecological cancer, 91 (0.
