RESUMO
Intraarticular ganglions are rare and they are usually incidental findings of MRIs and arthroscopies. We report the case of a male athlete with this condition affecting the anterior cruciate ligament. The most frequent symptoms include pain that worsens with activity, and motion limitations. The MRI shows the typical signs of a ganglion and it is the most specific and sensitive test. Arthroscopy is used for both the diagnosis and the treatment of this condition. A late diagnosis turns arthroscopic resection into a complicated or impossible procedure that at times warrants extensive debridement of the anterior cruzate ligament.

INTRODUCTION: Anterior tibial tubercle fractures are relatively infrequent and occur mainly in young athletes 14 to 17 years old. Most fractures result from jumping during sports activities. METHODS: We describe two cases of anterior tibial tubercle fractures. The latter were Ogden IIIA and IIIB. In both cases treatment consisted of open reduction and internal fixation with cannulated screws. DISCUSSION: The mechanism of injury in the first case is more common than the one in the second case. The first case occurred after jumping to receive a pass during a basketball game. The second one occurred while playing soccer. The patient was kicked on the quadriceps musculature. Both cases involved functional disability. CONCLUSION: Biomechanically, the mechanism of injury in the second case increased the tension on the extensor apparatus. We performed synthesis with cannulated screws and obtained good results without complications.

Authors have studied most of the known species of Triatominae with Scanning Electron Microscopy (SEM) JEOL and HITACHI S-500. They were able to photograph structures in these bugs belonging to the 5 known tribes. 12 of the 14 genera existing on the American Continent and Caribbean Islands, and 98 of the 111 recognized species of the subfamily. It was not possible to study either Bolbodera or Parabelminus with SEM

Essential thrombocythemia is an entity characterized by clonal proliferation of megakaryocytes and thrombocytosis. We have analyzed the presenting manifestation of 13 patients with Essential Thrombocythemia diagnosed in the last three years. The major findings include the frequent presence of symptomatology of a hypercoagulable state with prompt improvement of these symptoms once the thrombocytosis is controlled. Constitutional symptoms, organomegaly, modest Leukocytosis and eosinophilia were also often seen. No catastrophic events were detected with a mean follow up period of 17.5 months.
