In 30 patients with hyperlipoproteinemia (19 type II and 11 type IV), the role of the intrinsic coagulation pathway was evaluated by assays of preK, Kl's, and Hageman factor (factor XII). Analysis of the plasma of type II patients suggested activation of the intrinsic pathway characterized by a 40% decrease in preK (p less than 0.01) and a 50% decrease Kl(More)
Thirteen asymptomatic women taking oral contraceptives (OCs) were compared with normal subjects. Platelet aggregation and serotonin (tagged with carbon 14) release with adenosine diphosphate, epinephrine, and collagen did not differ from controls. Activation of the intrinsic coagulation pathway was evaluated by measurements of factor XII, prekallikrein, and(More)
Gorlin-Goltz syndrome, or nevoid basal cell carcinoma syndrome (NBCCS), is a rare autosomal dominant disorder caused by mutations in the PTCH1 gene and shows a high level of penetrance and variable expressivity. The syndrome is characterized by developmental abnormalities or neoplasms and is diagnosed with 2 major criteria, or with 1 major and 2 minor(More)
In the framework of censored regression models, the distribution of the error terms departs significantly from normality, for instance, in the presence of heavy tails, skewness and/or atypical observations. In this paper we extend the censored linear regression model with normal errors to the case where the random errors follow a finite mixture of Student-t(More)
Congenital anomalies of genital region frequently occur but congenital scrotal anomalies are not common and few cases have been reported in the literature. Among these reported anomalies the accessory scrotum is the lowest incidence principally when not associated with other congenital anomalies. The authors reports a case of accessory perineal scrotum(More)
