BACKGROUND Cancer risk and Lhermitte-Duclos disease (LDD) risk estimates for Cowden syndrome (CS) are broad and based on a small number of patients. Risk estimates are vital to the development of diagnostic criteria, genetic counseling, and cancer surveillance. To further elaborate and estimate the risks associated with CS, a large cohort of patients was evaluated. METHODS CS patients were id...

Predicting forest-tree seed dispersal across a landscape is useful for estimating gene flow from genetically engineered (GE) or transgenic trees. The question of biocontainment has yet to be resolved, although field-trial permits for transgenic forest trees are on the rise. Most current field trials in the United States occur in the Southeast where Pinus taeda L., an indigenous species, is the ...

PTEN is a tumor suppressor gene mutated in many human sporadic cancers and in hereditary cancer syndromes such as Cowden disease, Bannayan-Zonana syndrome and Lhermitte-Duclos disease. The major substrate of PTEN is PIP3, a second messenger molecule produced following PI3K activation induced by variety of stimuli. PIP3 activates the serine-threonine kinase PKB/Akt which is involved in anti-apop...

Following lumbar extradural analgesia with 0.5% bupivacaine, the placental transfer of bupivacaine was examined in 40 women undergoing elective and 40 women undergoing emergency Caesarean section. Within each group, the patients received randomly either plain bupivacaine or bupivacaine with adrenaline 1 in 200,000. Plasma bupivacaine concentrations were measured in blood samples taken simultane...

INTRODUCTION Epiphysiodesis has become one of the most popular methods in the treatment of leg length discrepancy (LLD) due to its surgical simplicity, short hospitalization time, and a low risk of complications. PATIENTS AND METHODS A retrospective analysis was performed on 34 patients treated for LDD with percutaneus epiphisiodesis of the distal femur and/or the proximal tibia. The mean dis...

The spatial variability of three indicators of learning and developmental disability (LDD) was assessed for Cape Cod, Massachusetts. Maternal reports of receiving special education services, attention deficit hyperactivity disorder, and educational attainment were available for a birth cohort from 1969-1983. Using generalized additive models and residential history, maps of the odds of LDD were...
