Background. Geriatric health care has become a worldwide concern, but a few statistical studies were carried out about skin diseases in this age group. In this study, we set out to determine the frequency as well as the age and gender distribution of dermatological diseases in geriatric patients. Materials and Methods. In a cross-sectional study, all patients over 60 years who were accepted to ...

conclusions since ki-67 is extensively accepted as an important biomarker in diagnosis, prognosis and treatment of cancerous and precancerous lesions, a high degree of presence of this biomarker in chronic precancerous lesions, such as erosive olp, can be of great use in prognosis and suggested treatments. objectives this study aimed to evaluate ki-67 expression in erosive and non-erosive oral ...

Gastric carcinoma is a common malignant disease associated with an unfavorable prognosis in the case of late dia-gnosis. The most significant precancerous condition is chronic atrophic gastritis and intestinal metaplasia caused by Helicobacter pylori infection. These longlasting changes may lead to formation of dysplastic precancerous lesions. Upper endoscopy and histologic examination of force...

Colorectal cancer (CRC) is a common and often lethal tumor. Over the last 25 years, remarkable progress has been made in understanding its biological and molecular features and in elucidating the steps involved in colon carcinogenesis. This, in turn, has led to a more rational and effective clinical approach to the treatment of CRC. While colorectal adenoma is the most frequent precancerous les...

Oral cancer continues to be a serious problem in the UK and it is well known that prevention and early recognition of potentially malignant lesions will provide the best prognosis. This article discusses recent changes in the nomenclature of lesions and current concepts in diagnosis and management.

background: the present study was undertaken to estimate and compare the levels of plasma total cholesterol (tc), low density lipoprotein (ldl), high density lipoprotein (hdl), very low density lipoprotein (vldl) and triglycerides in patients with oral precancerous lesions/conditions, oral cancer and normal subjects. materials and methods: the study comprised of 60 patients with oral precancero...

The present study aimed to investigate the feasibility of detecting p33 inhibitor of growth 1b (p33ING1b) gene methylation in fecal DNA as a screening method for colorectal carcinoma (CRC) and precancerous lesions. The methylation of p33ING1b was analyzed in fecal samples from 61 patients with CRCs, 27 patients with precancerous lesions (advanced adenoma) and 20 normal individuals by nested met...

To dissect the role of constitutively altered Tgfbr1 signaling in pancreatic cancer development, we crossed Elastase-Kras(G12D) (EL-Kras) mice with Tgfbr1 haploinsufficient mice to generate EL-Kras/Tgfbr1(+/-) mice. Mice were euthanized at 6 to 9 months to compare the incidence, frequency, and size of precancerous lesions in the pancreas. Only 50% of all EL-Kras/Tgfbr1(+/-) mice developed prein...
