Summary form only given, as follows. As part of their PAC system, the authors are developing two types of workstations to meet the needs of both the radiologists and referring physicians. In examining these needs, they found a difference in requirements. Radiologists are most interested in a workstation which can emulate a CT viewing console and provide some added capability. Referring physician requirements are either for a very simple viewbox-like system, or (for some specialists) much more elaborate graphics displays. The authors examine the reasons for these requirements and their approaches to fulfilling them

A review of the current status of penile artery revascularization and its methodology is presented. Microsurgical anastomosis of the inferior epigastric artery or central arteries produces good results in younger men. Older patients or those with diabetes, hypertension or who have had coronary bypass surgery do not appear to have good results

Three young men with impotence due to a pudendal arteriovenous malformation had a common selective pudendal arteriographic finding of early passage of contrast medium from the bulbar artery region into the venous drainage of the pelvis. Perineal exploration revealed the malformation and correction resulted in significant restoration of erectile capacity. This entity may be a frequent occurrence in young men that may become apparent only when trauma or disease affects the contralateral pudendal artery or its branches

In nine adult baboons, full-thickness skin grafts were reciprocally exchanged between three glabrous skin sites on one hand and glabrous skin sites on the contralateral hand or foot, and a hairy skin site on the dorsum of the ipsilateral hand. The grafts acquired some of the physical characteristics of the recipient site; glabrous skin became thinner and more pliable on the dorsum of the hand and hairy skin became thicker and displayed a more irregular surface contour when transferred to the palm. The electrophysiological properties of cutaneous mechanoreceptors serving these grafts were examined about 5 months after surgery and again after 1 year. Measurements of conduction velocity, receptive field size and shape, and responses to mechanical stimuli suggested that axons serving mechanoreceptors in glabrous grafts functioned at nearly normal levels by 5 months, while axons innervating hairy skin grafts, whether transferred to a glabrous skin site or to a hairy skin site, performed less well even after 1 year. These observations suggest that factors intrinsic to the graft are a major determinant of the quality of sensory function achieved following a skin graft procedure. These factors affect the relative proportions of rapidly and slowly adapting fibres, conduction velocities, thresholds and receptive field configurations. As a result, hairy skin is not the tissue choice for plastic surgical procedures requiring optimum sensory return

Nerve grafting has made advances in the last 100 years. One of the most significant of these was realizing the importance of adequate blood supply for successful nerve grafting. The vascular anatomy of the six potential vascularized donor nerves we have reviewed may prove to be extremely useful in reconstructing proximal nerve lesions, large nerve defects, and compromised recipient beds

13 cases of Goldenhar-Gorlin syndrome are presented in which numerous central nervous system anomalies have been found. These include occipital encephalocele, hydrocephalus, aqueductal stenosis, agenesis of corpus callosum, multiple congenital lipomas and many others. Pertinent literature has been reviewed. It is concluded that any part of the central nervous system can be involved in this condition and that careful evaluation is indicated in order to rule out a treatable intracranial anomaly
