Article Abstract
Purpose: The skin tumors can occur on any part of the body, these anatomical subunits are considered prognostic factors for localized carcinomas. Tumor size is a prognostic criterion that also varies according to the anatomical location of these tumors. Head and neck region is the most common location. This study aimed to investigate the distribution of BCC, SCC, and MM in the anatomical subunits of the head and neck region and their relationships with these anatomical subunits.
Materials And Methods: Patients who underwent surgery for BCC, SCC, BSCC and/or MM in the head and neck region. The head and neck region was divided topographically into the following subunits: scalp, forehead, orbital region, ear and periauricular region, cheeks, nose, perioral region, and neck. Patients were analyzed according to age, sex, and tumor location, type, and size.
Results: The SCC group was found to have significantly larger mean tumor size than the BCC group (p = 0.003). SCC was more frequently located in the perioral region (p = 0.001), BCC was more frequently located on the nose (p = 0.001), and MM was more frequently located on the forehead and scalp (p = 0.034, p = 0.49) when compared with the other types. BCC was more frequently located in the orbital region than SCC (p = 0.018) CONCLUSIONS: In this study, we observed statistically significant differences in the distribution of BCC, SCC, and MM, the most common types of skin cancer, among the topographical subunits of the head and neck region.

Objectives: As one of the most common complications of laryngopharyngeal reflux or gastroesophageal reflux disease, dental erosion presents a significant association with laryngopharyngeal reflux. This study aimed to elucidate the role of laryngopharyngeal reflux and gastroesophageal reflux disease on the severity and occurrence of dental erosion in adult populations.
Methods: A comprehensive search was performed in the databases of PubMed/MEDLINE, Web of Science, Cochrane Library, and Scopus for English literature published from July 1999 to June 2024.

Background: Heterozygous TRPV4 mutations cause a group of skeletal dysplasias characterized by short stature, short trunk, and skeletal deformities.
Objective: The aim of this study is to compare the natural history of clinical and radiologic features of patients with different TRPV4-related skeletal dysplasias.
Materials And Methods: Thirteen patients with a mutation in TRPV4 were included in the study, and 11 were followed for a median of 6.

As the most common and lethal cancer of the female gonads, ovarian cancer (OC) has a grave impact on people's health. OC is asymptomatic, insidious in onset, difficult to diagnose and treat, fast-growing, and easy to metastasize and has poor prognosis and high mortality. How to detect OC as early as possible and treat it without side effects has become a challenging medical problem.

The present systematic review aims to put together human population studies that include some relationship between genetic polymorphisms and genotoxicity as well as to evaluate the quality of the published studies induced by cigarette smoke exposure in vivo. The present systematic review was built according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Different genotoxicity assays were used by different authors, although the major goal was the genotoxicity assessment by means of micronucleus, comet, sister chromatid exchange, and chromosomal aberration assays.
