We present a case of a patient submitted for extirpation of a neoplasm of the larynx, by means of carbon dioxide laser surgery. High frequency jet ventilation was applied by means of orotracheal intubation with two Teflon catheters, 2 mm in external diameter and 30 cm in length, attached with three equally placed strips of adhesive paper tape. One catheter(More)
A case of menouria (Youssef's syndrome) following a vesicovaginal fistula repair is presented. The patient had typical clinical features of cyclic hematuria, absence of vaginal bleeding and complete urinary continence. Diagnosis was established by cystoscopy, cystography and hysterosalpingography which disclosed the communication between the bladder and the(More)

Perhaps the most compelling new trend in system-level semiconductor design is the concept of application “platforms”. Such platforms are intended to make the development of complex, application-specific systems-on-chip (SOCs) an order of magnitude faster and more reusable. They may provide either functional and infrastructure IP, or both, as well as(More)
Following determination of minimum alveolar anesthetic concentration (MAC) of halothane during normotension, 18 dogs were divided into three groups. Dogs in each group then received either pentolinium, trimethaphan, or sodium nitroprusside, and mean arterial pressure was decreased to 60% of control values for 1 hour. The MAC of halothane was determined(More)
