Lateral projections with inclined head for angiography of basal cerebral aneurysms.

Inclined lateral projections prove useful in defining aneurysms situated about the circle of Willis. For these projections, the x-ray tube and film changer are positioned as for a true lateral projection. The MCA lateral projection (patient's head inclined away from the side of injection) is valuable in investigating aneurysms of the internal carotid artery, posterior communicating artery and middle cerebral artery trifurcation. The ACA lateral projection (head inclined toward the side of injection) may be used to define aneurysms in the region of the anterior communicating artery.     

Nature of the conduction disturbance in selective coronary arteriography and left heart catheterization

The electrocardiographic changes associated with coronary arteriography were compared with those occurring during left ventricular catheterization in 16 patients. In 1 patient, a 36 year old man, transient left anterior divisional block was documented when the catheter tip was in the outflow tract of the left ventricle. The ÂQRS shifted from +90 to −50°, the initial 0.02 second QRS forces shifted interiorly and to the right, and the QRS interval increased from 0.07 to 0.09 second, fulfilling previously described criteria for the diagnosis of left anterior divisional block. This was attributed to transient injury of the anterior division of the left bundle branch. During recovery, several progressively decreasing degrees of left anterior divisional block were recorded.     

Uveitis and cerebral reticulum-cell sarcoma (large-cell lymphoma). Case report.

A patient with a peculiarly refractoy uveitis and vitritis was later found to have an infiltrative mass lesion of the posterior portion of the corpus callosum. The histopathological diagnosis of reticulum-cell sarcoma (large-cell lymphoma) was made after study of vitreous tissue obtained by pars plana vitrectomy of the right eye. Intraocular involvement with cerebral reticulum-cell sarcoma has been reported previously.     

Propranolol and depression revisited: three cases and a review

The occurrence of major depressive episodes as complications of treatment with propranolol has been a matter of controversy. Three cases are reported of depressions meeting DSM-III criteria following administration of propranolol for medical conditions. Possible relationships between beta blockade and affective illness are discussed.
