OBJECTIVE This study aimed to develop and validate a model to estimate the likelihood of detecting advanced colorectal neoplasia in Caucasian patients. DESIGN We performed a cross-sectional analysis of database records for 40-year-old to 66-year-old patients who entered a national primary colonoscopy-based screening programme for colorectal cancer in 73 centres in Poland in the year 2007. We ...
Human papillomavirus causes anal condylomata, high-grade anal intraepithelial neoplasia, and anal squamous cell cancer. We found high-grade intraepithelial neoplasia or squamous cell cancer in 75 (47%) of 159 HIV-seropositive men who have sex with men (MSM) and in 42 (26%) of 160 HIV-seronegative MSM with anal condylomata meriting surgery (P<.001, determined by use of the chi(2) test). Anal con...
BACKGROUND The incidence of neoplasia after surgery has not been sufficiently evaluated in patients with ulcerative colitis (UC), particularly in the Japanese population, and it is not clear whether surveillance endoscopy is effective in detecting dysplasia/cancer in the remnant rectum or pouch. The aims of this study were to assess and compare postoperative development of dysplasia/cancer in p...
UNLABELLED Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells. This review summarizes data found in the literature regarding the applications of Doppler ultrasound in managing patients with gestational trophoblasti...
Disseminated neoplasia, a diffuse tumor of the hemic system, is characterized in many bivalve mollusks by hemolymph containing 1–100% mitotic hemocytes. Little is known about the onset and chronic distribution of neoplasia in populations of Mya arenaria (Soft-shell Clam), though studies have reported episodic exposure to environmental contaminants or an infectious agent as a potential cause of ...
Background: Methotrexate is used in the treatment of Low-risk Gestational Trophoblastic Neoplasia. The purpose of this study was to compare the therapeutic responses and side effects of two therapeutic methods which were prescribed for patients suffering from Low-risk Gestational Trophoblastic Neoplasia. One method was the daily use of Methotrexate-Folic Acid (for 8 da...
Background: Complete molar twin pregnancy with coexisting fetus is a rare and important diagnosis in obstetrics. Preeclampsia, preterm labor and life-threatening vaginal bleeding are the serious complications of this type of pregnancy. Gestational trophoblastic neoplasia should be ruled out after termination of pregnancy. In this study we reviewed a molar twin pregnancy with a live coexisting t...
Intraepithelial neoplasia is of critical importance to the cancer chemoprevention field because it is a target condition for which drugs must be sought that will prevent its development or stop its progression. The term "dysplasia" refers to the morphological alterations that characterize intraepithelial neoplasia and according to many authors consists of seven basic morphological changes that ...
BACKGROUND AND AIM Crohn's colitis (CC) is associated with primary sclerosing cholangitis (PSC). However the risk of colon cancer or dysplasia in CC and PSC is unclear. Our aim was to study the risk of colon neoplasia in CC in patients with and without PSC. METHODS This is a nested, case-control cohort study of all patients diagnosed with concurrent CC and PSC, seen at the Cleveland Clinic be...
BACKGROUND Endoscopic tri-modal imaging (ETMI) incorporates white light endoscopy (WLE), autofluorescence imaging (AFI) and narrow-band imaging (NBI). AIMS To assess the value of ETMI for the detection and classification of neoplasia in patients with longstanding ulcerative colitis. DESIGN Randomised comparative trial of tandem colonoscopies. SETTING Academic Medical Centre Amsterdam, Net...
