A patient with hepatic angiosarcoma is described. The significant aspects of this malignancy are delineated. This tumor constitutes only 2% of all primary tumors of the liver. The association with exposure to vinyl chloride and other carcinogens is reviewed. Diagnostic and therapeutic modalities are discussed.
One of the more fascinating aspects of patient management arises when dealing with coagulation disorders. Factor XII deficiency, first described by Ratnoff in 1968, is one such coagulation disorder which provides some interesting challenges in management. Factor XII deficiency has been shown to be an inherited autosomal recessive disorder. The presence of Hageman factor abnormality trait can be clinically suspected in a patient with a prolonged activated partial thromboplastin time (APTT), normal prothrombin time (PT), normal bleeding time, and no clinical history of bleeding. Once suspected, the deficiency can be confirmed by normalization of partial thromboplastin time (PTT) with normal aged plasma and by factor assay. The importance of understanding the mechanism of factor XII deficiency has clinical significance when attempts are made to heparinize individuals who have this deficiency. Three methods can be used to monitor therapy: the chromogenic heparin assay, the citrated thrombin time, and the recalcified thrombin time. Two cases are presented.
Valentine Shortis, a young Irish immigrant, was convicted of murder in Quebec in 1895. His insanity defence was unsuccessful in spite of psychiatric evidence given by the leading psychiatrists in Canada. Shortis spent the next 42 years in custody. The case provides a good vehicle for exploring a number of aspects of the history of psychiatry, the insanity defence, and the treatment of the criminally insane in Canada. Comparisons are made with the insanity defence and the treatment of the criminally insane today.
