Comparison of television and telephone for remote medical consultation.

Television and telephone communications were randomly used to compare their effectiveness in allowing consultation between a hospital-based physician and remote nurse practitioners. Visits using television for consultation averaged 50 minutes as compared with 40 minutes for telephone. This difference was caused by longer work-ups before the consultation, longer delays after it was requested, and longer consultations, themselves, on television. However, television consultations resulted in significantly fewer immediate referrals of patients to hospital physicians: 6 plus or minus 1 as compared to 12 plus or minus 1 per cent (mean plus or minus S.E.M) OF ALL TELEPHONE CONSULTATIONS (P SMALLER THAN 0.005). Although no overall difference in satisfaction was documented between the results of television and telephone consultations, participants preferred the former for medical decision making and cited it for allowing more social interaction than telephone. These findings suggest that television may have its greatest value in remote sites where the sense of isolation is great and the need to reduce long-distance referrals offsets the costs of the system.

The fate of fresh, layered, nonsutured and sutured, autogenous cartilage in the rabbit model.

OBJECTIVE: To compare the thickness, area, and volume of sutured and nonsutured multilayered cartilage grafts in a rabbit population. DESIGN: Autogenous rabbit cartilage grafts were harvested, layered, and placed in the contralateral auricle. Half the grafts were sutured; the other half were nonsutured. Graft thickness, area, and volume were measured before implantation, after 90 days in vivo, and after explantation. RESULTS: The area and volume of the cartilage grafts increased during the 90-day period. Histologically, this was caused by increased fibrous tissue around the cartilage grafts. Minimal cartilage resorption was observed. No differences were noted between sutured and nonsutured grafts. CONCLUSIONS: Autogenous, fresh, uncrushed, layered nonsutured or sutured cartilage grafts are well tolerated. Statistically significant increases in the area and volume of autogenous, fresh, uncrushed, layered cartilage grafts occurred primarily because of fibrous tissue formation at the margins of the layered grafts. Suturing had no effect on the postoperative volume retention of these layered grafts. This information will be helpful to the facial plastic surgeon when using fresh-layered autogenous cartilage grafts during cosmetic or reconstructive procedures.

Abductor hallucis tendon transfer for hallux varus.

Hallux varus deformity, which may be either congenital or acquired, can be very painful and disabling, in addition to having a poor cosmetic appearance. In this paper, the author discusses the acquired type. He believes the abductor hallucis tendon transfer to be the procedure of choice for correction of hallux varus deformity, and he discusses its use and results in three cases.
