ABSTRACT
A comparative study was made of two methods of cartilage preservation, 98% glycerol and 70% alcohol. Rib cartilage was treated by either of these methods and transplanted into the malar process of rats. Cartilage grafts preserved by both methods were equally well tolerated. Resorption and bone substitution were similar in both groups after 120 days, although resorption was greater for the alcohol-preserved cartilage up until day 30. The possible reduction in antigenicity by the 98% glycerol did not produce any difference of behavior from the cartilage preserved in 70% alcohol.

Using a questionnaire, 41 patients scheduled for orthognathic surgery were evaluated pre- and postoperatively to determine some of their psychological characteristics and treatment outcome from the patient's standpoint. Among other conclusions, the results showed that some patients may not fully understand the details of their deformity, despite a full explanation by the orthodontist and surgeon. Expectations regarding treatment outcome may be unrealistic even in patients with valid self-motivation for surgery. Social adjustment usually improves after treatment. Functional changes were noticed by over 80% of the patients and esthetic changes in over 90%.

In 1986 legislation established the Virginia Congenital Anomalies Reporting and Education System (VaCARES). The system has three goals: to collect data that can be used to evaluate possible causes of congenital anomalies, to improve diagnosis and treatment, and to let parents and physicians know what resources are available to aid children born with anomalies. All children (from birth to age 2) with congenital anomalies admitted to Virginia hospitals after January 1, 1987, are being reported to VaCARES; VaCARES then contacts their families and physicians. Before the system was implemented statewide, its procedures were thoroughly tested through two pilot projects in selected hospitals. During the pilots, it was concluded that birth certificates alone are inadequate for case ascertainment. According to hospital reports, the incidence of all congenital anomalies during Pilot II was 562 out of 10,034 births (5.6%); birth certificates showed an incidence of only 83 out of 10,034 births (0.8%). During Pilot I, 3,466 (73.8%) of the diagnoses reported were perinatal conditions; the list of reportable conditions was accordingly altered, reducing perinatal conditions reported in Pilot II to 5 diagnoses (0.4%). It was estimated that there will be about 5000 to 7000 reports submitted to VaCARES each year. It was also shown that parents should be sent general rather than specific information about their child's birth defect and that quality control and close contact with reporting hospitals are essential to maintain the integrity of the registry data.
