History of SO2 removal system at the Meramec plant of union electric.

In line with the then emerging air pollution control regulations Union Electric installed a limestone injection wet scrubber sulfur dioxide removal system on an intermediate size coal-fired utility boiler at its Meramec Power Plant on an experimental basis in September, 1968. Approximately 3 years of operation many difficulties were encountered with plugging and scaling of various system components by calcium sulphate. As a result of this experience along with related experiences by other utilities employing similar systems, the experiment was terminated in June, 1971. As a result of the experiences gained, however, second generation experiments in sulfur dioxide removal have been initiated elsewhere with the hope of improved performance. A number of experimental projects are still under tests. Costs in resources, reliability, and disposal of residual by-products are matters of great concern. The ture cost of sulfur dioxide removal systems in dollars and resources is not well known and perhaps a reevaluation of current and future SO2 removal projects is in order at this time before additional resources are committed.

Coarctation of the aorta in male cousins with similar maternal environmental exposure to insect repellent and insecticides.

Two male infants, whose mothers are sisters and whose fathers are unrelated, were born within two weeks of each other. Both infants had coarctation of the aorta. Since both mothers were exposed to an insecticide while on a camping trip in the first trimester of pregnancy, it is unknown whether genetic or environmental factors caused the anomalies. Observations should be made on other patients with congenital heart defects to clarify the etiologic factors.

Current practice of occupational therapy for children with autism.

OBJECTIVE: The purpose of this study was to examine the current practice patterns of occupational therapists experienced in working with children with autism spectrum disorders. METHOD: Occupational therapists experienced in providing services to 2-year-old to 12-year-old children with autism completed a mail questionnaire describing practice patterns, theoretical approaches, intervention techniques, and preferred methods of preparation for work with children with autism. RESULTS: Of those contacted, 72 occupational therapists met the study criteria and returned completed questionnaires. Practice patterns included frequent collaboration with other professionals during assessment and intervention. Intervention services were typically provided in a one-to-one format with the most common techniques being sensory integration (99%) and positive reinforcement (93%). Theoretical approaches included sensory integration (99%), developmental (88%), and behavioral (73%). Evaluations relied heavily on nonstandardized tools and clinical observations. Educational methods identified as most helpful were weekend workshops (56%) and on-the-job training (52%). CONCLUSION: This study clarified the nature of current occupational therapy practice patterns for 2-year-old to 12-year-old children with autism. Additional studies are needed to examine the efficacy of current evaluation and intervention methods, as well as to explore the relevance of available standardized assessments for this population.

Changes in gait at 1 year post-selective dorsal rhizotomy: results of a prospective randomized study.

We performed a prospective randomized trial to compare the effects of selective dorsal rhizotomy with intensive physical therapy to intensive physical therapy alone in a group of children with mild spastic diplegic cerebral palsy. Instrumented gait analysis was carried out upon enrollment into the study and after 1 year. Changes in ambulatory status, time/distance parameters, and gait kinematics were observed for both groups. Considerable variability was present in both groups. Changes in ankle dorsiflexion, foot progression angle, and hip and knee extension in stance were significantly better in the selective dorsal rhizotomy group compared to the physical therapy group at 1 year (p < 0.05). These differences were not associated with significant improvements in functional gait as determined by changes in time/distance parameters or ambulatory status.
