OBJECTIVE To deal with public and professional concern regarding possible overprescription of attention-deficit/hyperactivity disorder (ADHD) medications, particularly methylphenidate, by reviewing issues related to the diagnosis, optimal treatment, and actual care of ADHD patients and of evidence of patient misuse of ADHD medications. DATA SOURCES(More)
Medical scientists and public health policy makers are increasingly concerned that the scientific discoveries of the past generation are failing to be translated efficiently into tangible human benefit. This concern has generated several initiatives, including the Clinical Research Roundtable at the Institute of Medicine, which first convened in June 2000.(More)
X-linked adrenal hypoplasia congenita (AHC) is a disorder associated with primary adrenal insufficiency and hypogonadotropic hypogonadism (HH). The gene responsible for X-linked AHC, DAX1, encodes a member of the nuclear hormone receptor superfamily. We studied an extended kindred with AHC and HH in which two males (the proband and his nephew) were affected(More)
Three years ago, we detected H-Y antigen in the white blood cells of a phenotypic female with several of the stigmata of Turner's syndrome, and the mosaic karyotype: 45,X/46,X,i(Xq). We surmised at the time that the isochromosome, i(Xq), may have contained occult Y-chromosome-derived material. We have now confirmed the presence of H-Y in this patient and we(More)
To improve plasma glucose control, we administered insulin via the subcutaneous route in seven ambulatory patients with juvenile diabetes (12 to 17 years of age), using a portable infusion pump at a basal rate with pulse-dose increments before meals. After two to four days, the mean plasma glucose (+/- 1 S.E.) of 94 +/- 5 mg per deciliter was markedly lower(More)
The clinical research infrastructure of the United States is currently at a critical crossroads. To leverage the enormous biomedical research gains made in the past century efficiently, a drastic need exists to reengineer this system into a coordinated, safe, and more efficient and effective enterprise. To accomplish this task, clinical research must be(More)
GH release in response to clonidine and human GH-releasing hormone-(1-44) (hGHRH-44) was assessed in 11 boys (aged 7-14 yr) with short stature, who had normal GH secretion. The response to these 2 provocative stimuli was repeated after, respectively, 2 and 3 days of treatment with human GH (0.1 U/kg, im). Exogenous GH significantly blunted the response to(More)
