Data from 2,764 Rottweiler dogs born from 1987 to 1996 were analyzed with a Restricted Maximum Likelihood procedure using a mixed linear animal model to obtain variance component estimates for hip and elbow dysplasia. The data included 2,764 hip dysplasia and 2,278 elbow dysplasia records. Hip joints were scored as normal (0), borderline (1), slight (2), moderate (3), and severe (4, 4.5, and 5)...

Glandular dysplasia in Barrett's esophagus may regress spontaneously but can also progress to cancer. The human telomerase RNA template and the human telomerase reverse transcriptase enzyme which do not, of themselves, correlate strongly with telomerase activity, are too often overexpressed in Barrett's dysplasia to predict individual cancer risk. This study relates telomerase activity, mucosal...

Ultrasound (US) imaging of an infant's hip joint is widely used for early detection of developmental dysplasia of the hip. In current US-based diagnosis of developmental dysplasia of the hip, trained clinicians acquire US images and, if they judge them to be adequate (i.e., to contain relevant hip joint structures), analyze them manually to extract clinically useful dysplasia metrics. However, ...

AIM To evaluate the efficacy and safety of liquid nitrogen cryotherapy as a primary or rescue treatment for BE, with and without dysplasia, or intramucosal adenocarcinoma (IMC). METHODS This was a retrospective, single-center study carried out in a tertiary care center including 45 patients with BE who was treatment-naïve or who had persistent intestinal metaplasia (IM), dysplasia, or IMC des...

IMPORTANCE High-resolution anoscopy (HRA) is becoming increasingly advocated as a method of screening for anal dysplasia in high-risk patients. OBJECTIVE To describe, through HRA findings, the association between patient symptomatology and anal dysplasia among patients at high risk for anal dysplasia. DESIGN, SETTING, AND PARTICIPANTS Univariable and multivariable analyses were conducted of...

BACKGROUND In contrast to longitudinal deficiencies, phocomelia is considered a transverse, intercalated segmental dysplasia. Most patients demonstrate severe, but not otherwise classifiable, upper-extremity deformities, which usually cannot be placed into one of three previously described phocomelia groups. Additionally, these phocomelic extremities do not demonstrate true segmental deficits; ...

Background Hip dysplasia is an abnormality of the hip joint where the socket portion does not fully cover the ball portion, which might increase the risk of joint dislocation. Hip dysplasia may occur at birth or develop in early life. The purpose of the present study was to assess the effect of treatment with Tübingen hip flexion splint for Dev...

The aim of the study was to evaluate the correlation of c-erb-b2 and Bcl-xl expression in biopsy specimens of Barrett's oesophagus from 44 patients with morphological features. The examined group was subdivided into: negative for dysplasia, indefinite for dysplasia, positive for dysplasia-low grade, and adenocarcinoma with high grade dysplasia. Positive c-erb-B2 staining was found in 34.1% and ...

Our aim was to determine whether abnormalities noted on MRI immediately after reduction for developmental dysplasia of the hip could predict the persistance of dysplasia and aid surgical planning. Scans of 13 hips in which acetabular dysplasia had resolved by the age of four years were compared with those of five which had required pelvic osteotomy for persisting dysplasia. The scans were analy...

The histopathology of 12 patients with adenoma of the ampulla of Vater was examined to trace the adenoma-carcinoma sequence of the ampulla of Vater. Immunohistochemistry for carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 was also performed. Four large adenomas with mild dysplasia also had foci of moderate dysplasia while another one contained foci of severe dysplasia (intramu...
