Herpes and polyoma family viruses in thyroid cancer.

Thyroid cancer is considered the most common malignancy that affects the endocrine system. Generally, thyroid cancer derives from follicular epithelial cells, and thyroid cancer is divided into well-differentiated papillary (80% of cases) and follicular (15% of cases) carcinoma. Follicular thyroid cancer is further divided into the conventional and oncocytic (Hürthle cell) type, poorly differentiated carcinoma and anaplastic carcinoma.

Investigation of BK virus, Epstein-Barr virus and human papillomavirus sequences in postoperative thyroid gland specimens.

Background: Although recent evidence has implicated viruses in the regulation of epithelial-to-mesenchymal transition and tumor progression, little is known regarding viral infections in thyroid malignancies. Thus the aim of this study was to detect sequences of 3 potentially oncogenic viruses - BK virus (BKV), Epstein-Barr virus (EBV) and human papillomavirus (HPV) - in a series of postoperative thyroid gland specimens.

Methods: Thirty patients with thyroid nodules who underwent surgery for thyroid disease within a 3-year period were enrolled.

Detection of human papillomavirus (HPV) DNA prevalence and p53 codon 72 (Arg72Pro) polymorphism in prostate cancer in a Greek group of patients.

Prostate cancer is the most common neoplasm found in males and the second most frequent cause of cancer-related mortality in males in Greece. Among other pathogens, the detection frequency of human papillomavirus (HPV) has been found to be significantly increased in tumor tissues among patients with sexually transmitted diseases (STDs), depending on the geographical distribution of each population studied. The present study focused on the detection of HPV and the distribution of Arg72Pro p53 polymorphism in a cohort of healthy individuals, as well as prostate cancer patients.

Detection and genotype analysis of human papillomavirus in non-small cell lung cancer patients.

Although the role of human papillomavirus (HPV) in the development of uterine cervical cancer is well established, the role of HPV in lung carcinogenesis remains controversial. The detection rates of HPV DNA are subject to a wide variation from 0 to 100%. This is partly influenced by the detection techniques employed.

Secondary rhinoplasty fixations with hyaluronic acid.

The management of nasal deformities especially after rhinoplasty is a challenge. Postsurgical edema may last 6-8 months, causing aesthetic irregularities and nose deformities. The aim of this study is to present the correction of minor nose deformities secondary to rhinoplasty using hyaluronic acid subdermal injections.

Expression analysis of B-Raf oncogene in V600E-negative benign and malignant tumors of the thyroid gland: correlation with late disease onset.

B-Raf, a member of the Raf serine/threonine kinase family, is an intermediate molecule in the mitogen-activated protein kinase pathway, which relays extracellular signals from the cell membrane to the nucleus via a cascade of phosphorylation events, ultimately promoting cancer development. This pathway is usually activated in human neoplasias. The purpose of this study was to investigate the role of B-Raf in thyroid pathology.
