Incidence of maternal Rh immunization by ABO compatible and incompatible pregnancies.

The incidence of maternal Rh immunization in Rh-negative women following a single ABO compatible Rh-positive pregnancy is about 17%. This incidence was determined by following Rh-negative women through two Rh-incompatible pregnancies and analysing their sera for anti-Rh at the time of delivery of their second observed pregnancy. Maternal Rh immunization occurs almost exclusively after delivery; however, antibodies may not be detectable in the absence of further antigenic stimulation.The incidence of maternal Rh immunization when maternal-foetal ABO incompatibility is also present is 9-13% and 17% for group O and non-group O women respectively. This study emphasizes the need to offer Rh-immune prophylaxis to Rh-negative women having Rh-positive infants whether or not ABO incompatibility exists between the mother and infant.

Agglutinating specificity for LW factor in guinea pig and rabbit anti-Rh serums.

Serums produced in guinea pigs or rabbits inocutlated with monkey (rhesuts or baboon) or human red cells contain the same high-incidence agglutinating activity found in human antiLW serumls. After one absorption with LW-negative blood cells. anti-LW specificity, was observed with stronger reactions on Rh-positive than Rh-megative cells. The 85-percent specificity was obtained after complete absorption with Rh-negative blood.

What follow-up studies say about postschool life for young men and women with learning disabilities: a critical look at the literature.

Follow-up studies examining the outcomes for children and youth with learning disabilities who attended special education have appeared in the literature for decades. As American society becomes more technologically advanced and competitive, postsecondary school opportunities and subsequent employment choices that are meaningful and provide a livable wage teeter out of the reach of young people with learning disabilities. Follow-up study investigators seek to understand how to better prepare youth to meet these challenges by studying their long-term outcomes. The authors review data from 13 frequently referenced follow-up studies regarding postschool outcomes, postsecondary education, and employment, with attention to gender differences, for youth with learning disabilities who were served by and graduated from special education programs nationwide. They take a critical look at contradictions in the findings and discuss five methodological issues that seem to influence the conduct and interpretation of follow-up studies: aggregating data across disability categories; combining data on graduates who have been out of school for unequal periods of time; ignoring the issues of missing data, participant attrition, and incomplete data sets; combining data from different informants; and using nonequivalent databases to make comparisons to a population with no disabilities. The authors provide recommendations for conducting follow-up research on the long-term quality of life of children and youth with disabilities and their families.

Modified constraint induced therapy: a randomized feasibility and efficacy study.

This case series examined the feasibility and efficacy of a modified constraint induced therapy (CIT) protocol administered on an outpatient basis. The Fugl-Meyer Assessment of Motor Recovery After Stroke (Fugl), Action Research Arm Test (ARA), Wolf Motor Function Test (WMFT), and Motor Activity Log (MAL) were administered to six patients between 2 and 6 months poststroke (CVA) exhibiting stable motor deficits and learned nonuse of the affected limb. Two patients then participated in half-hour physical and occupational therapy sessions three times/week for 10 weeks. During the same period, their unaffected arms and hands were restrained 5 days/week during 5 hours identified as times of frequent use. Two other patients received regular therapy and two control patients received no therapy. The ARA, Fugl, WMFT, and MAL were again administered after 10 weeks. Patients receiving modified CIT exhibited substantial improvements on the Fugl, ARA, and WMFT, as well as increases in amount and quality of use of the limb using the MAL. Patients receiving traditional or no therapy exhibited no improvements. Results suggest that modified CIT may be an efficacious method of improving function and use of the affected arms of patients exhibiting learned nonuse.
