RESUMO
Television transmission of diagnostic and educational information can help to improve specialized medical care in remote and underserviced areas. This paper describes a pilot study in which the Canadian satellite Anik-B was used to link the James Bay area in northern Quebec with two large Montreal teaching hospitals. Broad-band real-time television was well suited for tele-education and teleconsultation activities. A much less costly method, using narrow-band slow-scan television, was also examined, but it requires improvements. The technology of telemedicine is in place, but its future use is impeded by the prohibitive costs of operating an efficient two-way broad-band television system for several remote health care sites. A solution to this problem may be an intermediate-band system combining some of the low-cost features of narrowband slow-scan television with the interactive high-resolution advantages of broad-band real-time television.

A case report and a review of this recently described entity are presented. A feature of interest in our case is the presence of Aspergillus fumigatus at the pulmonary needle biopsy as well as in the surgical specimen. This finding is described for the first time in a non asthmatic patient.

A two-way television network using the Canadian satellite ANIK-B was utilized to transmit radiographic images from Northern Quebec to Montreal. The accuracy of the radiologist's interpretation and his satisfaction with the TV system were studied using a series of 67 preselected cases and 425 current clinical cases. The four participating radiologists gave correct TV interpretations in 81% of the 39 selected cases presented at the beginning of the experiment. This value reached 94% for the other 28 selected cases presented after three months of regular use of the TV system. With current clinical cases, the agreement between TV and direct interpretations was 93%. Although magnification was available, correct identification of very small lesions proved to be the major source of error. On the whole, the radiologists were satisfied with the TV system.

Fourteen patients with bony lesions of the thoracic wall, seven benign and seven malignant, were evaluated. In lesions with an aggressive appearance on plain films, computed tomography proved to be very accurate for mapping their extent, and for evaluating adjacent organ involvement. For non-aggressive bony lesions of the chest wall, plain films are sufficient for determining the nature of the lesion.

Cases of ureteropelvic (UP) obstruction presenting for the first time in the adult were analyzed and etiologic factors considered. Besides idiopathic causes, calculi and neoplasm were found in our series. Comparison with other reports of UP obstruction in pediatric patients revealed differences pertaining to mode of clinical presentation, sex predominance and incidence of neoplasm occuring at the UP junction in the adult.
