Compression force rupture experiments were conducted in dog eyes at varying time intervals after scleral diathermy to determine the time variable of scleral weakening and recovery. The sclera was weakened immediately after the diathermy, and there was progressive further weakening for three weeks and then gradual partial recovery to 60% of control eye strength at eight months, at which point the experiment was terminated.

PURPOSE: Edwin Beer introduced the first endoscopic treatment of papillary bladder tumors in 1910. This historical review describes how his landmark discovery paved the way for office cystodiathermy to treat recurrent papillary tumors. MATERIALS AND METHODS: The medical writings of Edwin Beer and all studies pertaining to the treatment of papillary bladder tumors from 1879 to the present were reviewed. RESULTS: Edwin Beer discovered that papillary bladder tumors could be destroyed through the ordinary cystoscope with high frequency current by electro-coagulation. This therapy revolutionized the treatment of bladder tumors. CONCLUSIONS: The legacy of Edwin Beer is that office fulguration of recurrent papillary bladder tumors has now become a practical reality due to recent changes in the histological classification of papillary tumors, better definition of their biological behavior and improved endoscopic equipment.
The history of open and subsequently stereotactic brain lesions for the relief of pain is traced. Important steps included recognition of the importance of the non-specific pain pathways and the differential effects of lesioning on nociceptive pain and on different elements of neuropathic pain. Although the advent of morphine infusion and deep brain stimulation has greatly eroded the number of destructive lesions made, new technical and conceptual advances must be carefully evaluated.

At the end of the 19th century, the early evolution of the specialty of neurological surgery was restricted by complications related to infection, increased intracranial pressure, and excessive intraoperative blood loss. These complications often caused mortality rates of 30 to 50%. An improved understanding of pathophysiological factors involved in increased intracranial pressure, along with meticulous surgical techniques learned from William Halsted, allowed Harvey Cushing to increase the safety of neurosurgical procedures that were then in their infancy. Cushing's later development of the "silver clip" and incorporation of electrosurgical techniques facilitated safe resection of brain tumors previously assumed to be inoperable. These pivotal accomplishments paved the way for the establishment of our specialty.

LE is a management modality offered, at present, to less than 5 per cent of all patients with carcinoma of the rectum. It is indicated, as a primary curative procedure, in the subgroup of patients with early lesions of a favorable histologic grade. It has also been used, for palliation, in patients with overt disseminated malignant disease or in patients too old or too ill, or both, to withstand a radical operation or unwilling to accept a colostomy. Various techniques have been described and can be divided into two categories: excision of the intact tumor, best suited for a curative procedure when tumor characteristics can be accurately determined, and tumor destruction therapy, more generally used for palliation. The results of local excision, compared with those of radical operations, are very good when a strict selection policy is implemented and coupled with adequate patient follow-up study.
