Hypertrophic Obstructive Cardiomyopathy

Americani. The Jensen (genetic) positioin on racial (lifferences in intelligence is well alnswered l)y PettigTew's consi(leration of environmental influences on intelligence ancl iintelligence testing (even tlhotuglh Pettigrew's article precdates the Jenseni controversy). Also consi(lere(d by Pettigrew is the social (lefinition of mental illness andl the impact of social class in creating al)plarent racial differences in mlental illness. The otlher articles in this section (lo not lhave the breadtlh or (lepth of Pettigrew's andl consicler-ratlher isolatedl aspects of the social (lefiinition of race, whlereas thie first section preseints a more balancedl andl far-rainging view of tlle biological nattuie of race. This restult is)erlhap)s inevitable, given tllat thle souirce of the articles (Eugenics Quarterly) is primuarily a biological publication, not a sociological one. Otlher ai-ticles in the secondl section coincern nonwhliite fertility rates, the racial implications of eulgenics, andcI the (lisa(lvantage(l sclhool chiil.

Thlle family members assulme many postures, ranging from "I was really quite mistaken many years ago" to "I knew I was correct all the time." The endl prodtuct of this sympositum is at the least interestinig ancd at the most a very positive exploration of the presenit state of knowledlge of the disease named.lhypertrophic obstrUctive car(liomyopathy. I believe we cani look forwardl to a tlhirdI symiposium some years from now after tlle adolescent hlas mattured even fturtlher and hiis basic biochemical (lerangemnent and long-range prognosis become better tunderstoodl.
