    Notes: Abstract  Fechtner syndrome, a disease in the spectrum of the hereditary nephridites, is a macrothrombocytopenia associated with sensorineural hearing loss, cataracts, nephritis, and characteristic leukocyte inclusions. Renal biopsy findings are consistent with those of Alport syndrome, and the associated renal disease is said to be unusual before mid to late adulthood. Here, we review the available literature on this disease and report two African-American pediatric patients with Fechtner syndrome who rapidly progressed to end-stage renal disease during adolescence. We conclude that chronic renal failure can occur at a young age in patients with Fechtner syndrome, with a possible relation to race/ethnicity. Fechtner syndrome, or other variants of Alport syndrome, need to be considered in patients presenting with proteinuria and thrombocytopenia.

    Notes: Abstract Adult female Sprague-Dawley rats were prepared with chronic cortical and muscle electrodes and i.v. cannulas, made tolerant to and physically dependent on morphine, and trained to lever press for i.v. morphine self-injections to maintain dependence. Methadone or l-alpha-acetylmethadol (LAAM) was then substituted for morphine in some of these rats. During self-maintained dependence on either morphine or methadone, head shakes appeared and increased in frequency before lever pressing for selfinjections. In contrast, there were fewer head shakes during LAAM dependence, which were evenly distributed over the entire duration of the interinjection interval. These findings suggest a relationship between head-shake distributions, drug-seeking behavior, and the pharmacodynamics of these three narcotics.
