Further experiences on experimental cerebral "no-reflow phenomenon".

The authors evaluate the effectiveness of combination groups of antiedema pharmacological agents on experimental transient bilateral cerebral ischemia. The results show that dexamethasone and furosemide appear to be the most useful combination group. However, the improvement of post-ischemic vascular re-perfusion is not different when these antiedema agents are employed simultaneously or when they are administrated alone. The experimental model allows the authors to evaluate various modalities of the injection of the dye and drugs. Better filling of the cerebral hemisphere in which the antiedema agents were injected through the common carotid artery is always recorded. Therefore, the authors conclude that the best way to obtain homogeneous post-ischemic vascular re-perfusion is to inject half of drugs through the left common carotid artery and half through the right common carotid artery.

Angiopathic parkinsonism: does it exist?

The Authors report on 150 cases of patients suffering from Parkinson's disease. The patients represent 8.3% of total parkinsonian patients and are selected on the basis of clinical and laboratory criteria that allow the diagnosis of "angiopathic parkinsonism" as an autonomous entity. Cerebral blood flow alterations in Parkinson's disease and associated dementing symptoms are also discussed. In conclusion, the Authors emphasize the usefulness of recognizing the "angiopathic parkinsonism" in view of therapeutical implications.

[Gastrointestinal stromal tumor as the cause of intestinal hemorrhage: description of a clinical case].

The term gastrointestinal stromal tumor describes a heterogeneous group of tumors of mesenchymal origin with particular histologic features. Their classification has recently been made possible thanks to numerous immunohistochemical and ultrastructural studies. We report the case of a patient who came to our attention because of serious anemia due to a gastrointestinal stromal tumor located between the second and third portion of the duodenum. This pathology, although not frequent, should be considered in the differential diagnosis of gastrointestinal bleeding. In these cases it is important to perform careful endoscopic inspection to the third portion of th duodenum, even when previous tracts evidence lesions that could be responsible for the patient's symptoms.
