RESUMO
This paper describes a simple system for the performance of slow continuous hemodialysis (SCHD) as a means of treating difficult and complicated cases of oliguric acute renal failure. The method, which employs access to the circulation via a double-lumen central venous catheter and a BSM 22 blood systems module, can be performed safely in the intensive care unit of a general hospital if closely supervised by a trained nephrologist. The results of treating 16 consecutive cases of complicated acute renal failure in a large general hospital without a hemodialysis unit are described. The method, whose simplicity makes it suitable for intensive care unit nurses without previous hemodialysis training, was not associated with any serious accidents or complications, and was tolerated well by even the most critically ill and hemodynamically unstable patients. The advantages of this approach over more traditional continuous arteriovenous hemofiltration (CAVH) are discussed.

Osteoarthrosis is described in a wild, 14-year-old coyote (Canis latrans) x dog (C. familiaris) hybrid shot in southeastern Nebraska. There was ankylosis of five vertebrae, the head of the left femur was absent, and periarticular osteophytes occurred throughout the skeleton. The age is significant because wild coyotes seldom live beyond 6 years and coyote x dog hybrids are considered to be less fit for survival in the wild than coyotes.

This study examined the effect of voice disorders on judgments of personality and appearance. One-hundred-and-five college students evaluated the personality and appearance characteristics of 12 speakers, four with normal voice quality, four with harsh-breathy voice quality, and four with hypernasal voice quality. A semantic differential procedure was employed to obtain ratings on 12 bipolar adjectives. Results indicate a significant difference between the normal and disordered voices. Voice disorders elicit more negative responses on judgments of personality and appearance of the speaker. These findings indicate that voice disorders warrant correction.
