ABSTRACT
BACKGROUND AND OBJECTIVE: With the increasing use of laser resurfacing, concerns have arisen about the biological hazards associated with the procedure. This study analyzed the potential bacterial and viral exposure to operating room personnel as a result of the laser smoke plume in CO2 laser resurfacing. STUDY DESIGN/MATERIALS AND METHODS: Thirteen consecutive patients underwent CO2 laser resurfacing. A HEPA filter in the smoke evacuator was used to collect specimens of the laser plume smoke for cultures. The study was controlled by a second filter exposed to room air. RESULTS: The 13 patients each had one bacterial, one viral, and one control culture (total, 39 specimens). In the control group, none of the 13 specimens had any growth. No viral growth has been found to date. Of 13 bacterial cultures, 5 resulted in growth of coagulase-negative Staphylococcus. Of these five positive specimens, one also had growth of Corynebacterium and one had growth of Neisseria. CONCLUSION: The potential exists for operating personnel to be exposed to viable bacteria during laser resurfacing.

The author describes the positive experiences of Cranston General Hospital, Osteopathic in establishing a 24-month program, combining an entry level rotating podiatric residency and a podiatric surgical residency. The program grew from a 12-month surgical program to become a 24-month program, using expanded training opportunities available in Brown University teaching hospitals. An improved quality of care and a greater fund of knowledge for the residents are two results of the 24-month training program. Recommendations and views about developing entry level residency programs are presented.

Capsular correction is an important part of the repair of hallux abducto valgus. In this paper, the authors discuss the tear-drop method of capsular repair--a method that can be used in all hallux valgus corrections, either alone or in conjunction with the dorsolinear capsulotomy and repair. They believe the tear-drop method has many advantages, among which is the fact that severe splinting and/or casting is not needed and the patient can walk in a surgical shoe almost immediately after surgery. Excellent results were obtained in a high percentage of their 288 cases.

The magnetic properties of samples of rock, fines, and magnetic separate from the fines from Apollo 11 have been measured. Native iron, or possibly nickel-iron, of submicroscopic particle size is the most important constituent, with minor contributions from ilmenite, paramagnetic iron minerals, and other iron-titanium oxides. The remanent magnetization of a sample of the micro-breccia rapidly acquires a viscous magnetization and does not appear to have a significant stable remanence. The crystalline sample has a weak natural remanence showing some stability.
