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)
OBJECTIVE To compare Hybrid Capture Tube (HCT) and the second-generation Hybrid Capture II (HC II) test for detection of high-risk human papillomavirus (HPV) DNA at the time of colposcopy. STUDY DESIGN Colposcopy and HPV testing were performed by HCT and HC II on 1,309 women for evaluation of abnormal Pap smears. Differences in the proportions were tested(More)
Using a 1982 to 1983 regional network data bank of 33,545 delivered infants, a study was conducted comparing 574 macrosomic infants weighing greater than 4500 g to a control group of 18,739 infants whose birth weights were 2500 to 3499 g. Macrosomic infants occurred in 1.7% of the deliveries. Women delivering macrosomic infants were significantly older, of(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)
OBJECTIVE The purpose of this study was to determine the risk and presentation of cervical intraepithelial neoplasia (CIN) 3 or cancer after colposcopic diagnosis of CIN 1 or less. STUDY DESIGN After colposcopy for an abnormal cytology, women with CIN 1 or less had annual cytology evaluations and high-risk human papillomavirus (HPV) tests (Hybrid Capture(More)
This paper presents a field study that compares natural language call routing with standard touch-tone menus. <i>Call routing</i> is the task of getting callers to the right place in the call center, which could be the appropriate live agent or automated service. <i>Natural language</i> call routing lets callers describe the reason for their call in their(More)
A study was done on the occurrence of neonatal seizures in 14,367 infants delivered by cesarean section in a perinatal region in 4 years. Although seizures occurred in 1% of all of these infants, small infants weighing less than 2500 gm at birth had the highest frequency (greater than 4%). Term infants delivered before labor (repeat cesarean section) had(More)
We describe the methods and hardware that we are using to produce a real-time demonstration of an integrated Spoken Language System. We describe algorithms that greatly reduce the computation needed to compute the N-Best sentence hypotheses. To avoid grammar coverage problems we use a fully-connected first-order statistical class grammar. The speech-search(More)
