Adamantinoma of the spine: case report.

OBJECTIVE: We report a patient with a cervicothoracic spinal and a mandibular adamantinoma. Adamantinoma is a rare malignant neoplasm of bone and, to our knowledge, there have been only five cases of spinal adamantinoma reported. The pathogenesis of the adamantinoma, as well as the management of this extremely rare spinal tumor, is reviewed. CLINICAL PRESENTATION: A 55-year-old man was admitted to our service with cervical pain and signs of C8 and T1 radiculopathy. On physical examination, cervical spine deformity, swelling in the left mandible region, and signs of C8 and T1 radiculopathy were observed. Neuroradiology examinations showed an osteolytic mass of the C6, C7, and T1 vertebral bodies, extending into the lateral masses and transverse processes. After surgical procedures, the patient had clinical improvement. INTERVENTION: Corpectomy of C6, C7, and T1 was performed through a cervicothoracic anterior approach. Anterior stabilization of the spine was obtained using an autologous iliac crest graft and osteosynthesis with an anterior plate. On a second procedure, posterior tumor resection and spinal stabilization were performed. After the 1-year follow-up examination, a new anterior procedure was performed because of tumor recidivity and spine instability. CONCLUSION: Adamantinoma, an extremely rare lesion, is a locally aggressive tumor with slow growth and the potential to metastasize. Although it is an extremely rare occurrence in the spine, adamantinoma should be considered on the diagnosis of tumors of the vertebrae. Neuroradiological examinations are not specific in the differentiation of this tumor from other conditions. This fact, coupled with the limited experience that most physicians in general have in dealing with this tumor, makes the diagnosis and treatment of adamantinoma challenging.

Giant pseudoaneurysm of the extracranial vertebral artery: case report

Pseudoaneurysms of the extracranial vertebral artery are extremely rare due to their deep location and the anatomical protection of this artery. They can be caused by cervical traumas (firearm inhuries, sports, hyperextension of the neck and iatrogeny). The authors report the case of a patient who developed a giant pseudoaneurysm of the extracranial vertebral artery after surgery for the removal of a tumor of the cerebellopontine angle in which surgical lesion of the artery occurred. Treatment was performed by endovascular approach. Literature is reviewed and comments are made on the physiopathogeny of the lesion and the different forms of treatment.

Perfil dos diabéticos e hipertensos em Caseiros - RS / Profile of diabetics and hypertensive patients in Caseiros - RS

Deciciu-se estudar as características dos pacientes com Hipertensäo Arterial Sistêmica e Diabete Melito em Caseiros-RS. Foi utilizada uma amostra de 262 indivíduos avaliados numa Feira de Saúde do município. A amostra constou de 83 homens e 179 mulheres, sendo 47 hipertensos, 17 diabéticos (8 pacientes diabéticos eram também hipertensos) e os restantes 206 foram considerados como grupo controle. Os resultados do estudo indicam que a HAS prevaleceu nas mulheres a partir da 5ª década com obesidade de predomínio troncular e nos homens a partir da 6ª década com obesidade sem predomínio troncular. Todos os diabéticos eram obesos com distribuiçäo troncular prevalecendo na 6ª década
