In an ever-changing business climate, the need for strategically oriented management increases, for the organization that is insensitive and unresponsive to its environment will not survive. The authors of this "Action Plan" examine the challenges facing the health industry and outline a series of actions for initiating strategic-driven management.
A case of leiomyosarcoma of the scrotum is presented. The tumor measured 3 X 2.5 X 2 cm and had been present as a slowly enlarging mass in the right scrotum for three months prior to excision. Light microscopy demonstrated the typical interlacing fasicles of neoplastic cells with eccentric cigar-shaped nuclei and electron microscopy confirmed the neoplastic cells to be of smooth muscle origin. A review of the world's literature revealed this to be the fifth reported case of leimyosarcoma confined to the scrotal wall.
Catecholamine-induced alterations of the myocardium were studied in 48 rats following a single subcutaneous injection of 40 mg Aludrin/kg body weight after different intervals following the injection by means of the HBFP stain described by LIE et al. (1971). As early as 5 minutes following application of Aludrin extensive areas with ischemic fuchsinorrhagic cells could be demonstrated. Six hours post injection a decrease in the extent of the alterations could be observed. Five weeks following the injection only small feathery strands of scar tissue could be found in the experimental animals as sequela of the effect of Aludrin. The stain according to LIE et al. (1971) employed by us allows earliest demonstration of (catecholamine-induced) ischemic alterations in the myocardium.
