In human subjects, aberrant crypt foci (ACF) can be classified as dysplastic or non-dysplastic using magnifying colonoscopy. Dysplastic ACF are thought to be a biomarker for the risk of colorectal cancer (CRC). Hyperinsulinemia and insulin-like growth factor-1 (IGF-1) have also been reported to be associated with an increased risk of CRC. To clarify this association, we investigated the relatio...
Peutz-Jeghers syndrome (PJS) is caused by mutations in the LKB1 gene. It is characterized by gastrointestinal polyposis and an increased cancer risk, mainly in the gastrointestinal tract. Mechanisms of PJS-associated carcinogenesis are unclear. We investigated the involvement of candidate genes and molecular pathways in PJS-associated gastrointestinal cancers and dysplastic hamartomas. Cases we...
OBJECTIVE The aim of this study was to evaluate three-dimensional (3D) distribution of acetabular articular cartilage thickness in patients with hip dysplasia using in vivo magnetic resonance (MR) imaging, and to compare cartilage thickness distribution between normal and dysplastic hips. DESIGN Forty-five dysplastic hips without joint space narrowing on radiographs and 13 normal hips underwe...
Human dysplastic kidneys are developmental aberrations which are responsible for many of the very young children with chronic renal failure. They contain poorly differentiated metanephric cells in addition to metaplastic elements. We recently demonstrated that apoptosis was prominent in undifferentiated cells around dysplastic tubules (Winyard, P.J.D., J. Nauta, D.S. Lirenman, P. Hardman, V.R. ...
BACKGROUND/AIM The vascular supply of dysplastic nodules (DN) is altered compared with surrounding cirrhotic nodules. Dysplastic nodules contain unpaired arteries which are isolated arteries unaccompained by bille ducts. In adition, capillarization or neovascularization is evident on CD34 and CD31 staining. The investigation of angiogenic profile of regenerative, dysplastic and nodules of hepat...
We previously reported a favorable histologic response of dysplastic nevi to topical tretinoin in three patients. To investigate the anticancer and cancer preventive effects of retinoids we have examined the effect of systemic isotretinoin on dysplastic nevi. After confirmatory baseline biopsies, eleven patients with the dysplastic nevus syndrome were treated with oral isotretinoin, 40 mg twice...
BACKGROUND Dys-megakaryopoiesis is defined as ≥10 % of dysplastic megakaryocytes in bone marrow smears by the World Health Organization. However, concordance rates for dysplastic megakaryocytes between different observers is low and, consequently, evaluation of dysmegakaryopoiesis is also often discordant. RESULTS We performed CD41 immune staining and proposed a systematic classification of d...
posttraumatic cerebral infarction is a rare complication and is an indicator of poor clinical outcome of head-trauma in spite of appropriate medical and surgical interventions. cerebellar infarction following head trauma is also very rare and only a few reported cases are available in literatures. a 2-year-old child sustained head injury in a car accident and underwent surgery because of cerebr...
