This report suggests modest changes in the criteria used for the diagnosis of ET and allows tentative recommendations concerning therapy. As outlined in Table I, we believe that absent stainable marrow iron does not necessarily indicate iron deficiency in these patients and that the serum ferritin and RBC mean corpuscular volume should be incorporated in(More)
Neural tube defects (NTD) are one of the most common birth defects and are caused by both environmental and genetic factors. The approach to identifying the genes predisposing to NTD, through linkage analysis and candidate gene analysis, is reviewed along with characteristics of a large, nationally ascertained cohort of families. Results from specific(More)
The sequential biopsies and the careful clinical and laboratory studies in this large prospective study of PV patients offer a unique opportunity to properly evaluate the diagnostic and prognostic importance of the biopsy and to study the complications of this condition. The results of the study to date confirm and extend previous studies. Because of the(More)

The PVSG study is unique in that it is prospective and composed of 432 patients randomized to three treatment arms. This study also provides the opportunity for serial studies of numerous sequential biopsies. Large numbers of cases with sequential biopsies covering the entire long course are essential to appreciate the full spectrum of tissue changes in(More)
Previously untreated patients who had anemia (hemoglobin level, less than or equal to 10 g/dL) caused by myelofibrosis (MF) (16 patients) or other myeloproliferative disorders (13 patients) were given the opportunity to participate in a prospective randomized study-to be treated either with 30 mg/day of oral fluoxymesterone and necessary transfusions or by(More)
A workshop was held 18 to 19 March 1991 at the National Institutes of Health to address critical issues in research concerning the chronic fatigue syndrome (CFS). Case definition, confounding diagnoses, and medical outcome assessment by laboratory and other means were considered from the perspectives of key medical specialties involved in CFS research. It(More)
The major conclusions of this position article are as follows: (1) In the absence of a history of a bleeding disorder, the bleeding time is not a useful predictor of the risk of hemorrhage associated with surgical procedures. (2) A normal bleeding time does not exclude the possibility of excessive hemorrhage associated with invasive procedures. (3) The(More)
