Training in fibreoptic tracheal intubation in the north of England.

Twenty-nine departments of anaesthesia in the North of England were questioned about the availability and teaching of fibreoptic tracheal intubation techniques. While 27 departments had both suitable equipment and trained consultant staff, only one offered formal teaching to all its junior anaesthetists.

Long-term storage of frozen lenticules for cryorefractive surgery.

We studied freezing rates, cryoprotectants, and storage times on keratocyte viability, using rabbit corneal buttons incubated in either KM-26, CPTES, K-Sol, or TC 199 for 30 minutes at 4 degrees C. Using a controlled freezing rate (2 degrees/min to -40 degrees C), viabilities were 69 +/- 7% for KM-26, 113 +/- 21% for CPTES, 0.1 +/- 0.08% for K-Sol, and 0 +/- 0% for TC 199. The KM-26 and CPTES were further studied in corneas stored one to 30 days at -80 or -196 degrees C; CPTES had a better cryoprotective efficacy over one, three, and seven days of -80 degrees storage, and at liquid nitrogen storage temperature (-196 degrees) over one, 14, and 30 days storage. The findings demonstrate the superiority of CPTES. It provides better viability than KM-26 under similar conditions, and may enable long-term frozen storage of lenticules for later use in cryorefractive surgeries, with minimal loss of keratocyte viability.

Health problems reported by residents of a neighborhood contaminated by a hazardous waste facility.

A symptom prevalence survey was conducted of a neighborhood exposed to airborne hazardous wastes. Residents' responses were compared to those of a nearby control population. The results revealed that the exposed group had more self-reported complaints referable to the respiratory system (wheezing, shortness of breath, chest discomfort, persistent colds, coughs), constitutional complaints (always fatigued, bowel dysfunction), and irregular heart beat. When the effect of a documented irritant source in a small portion of the control population was removed, the exposed group also complained more often of irritation of the eyes and nose. There was a biological gradient for several of these effects. Efforts to eliminate the influence of confounding and recall bias are discussed. The results suggest either that the general population reacts to chemicals at levels much lower than the available occupational literature would indicate or that the effects are more long lasting than previously thought.
