With the exploration of new horizons in the frontiers of genetic linkage with head and neck cancer by advanced molecular biological technique it may be possible to know the various steps involved in the cancer development and new prognostic markers for not only predicting prognosis but also progression and predisposition including routine diagnostic tests for mutantgenes for a better diagnosis and treatment of squamous cell cancers of head and neck. Various oncogens and their products so far identified are ras, myc, c-erb, Bl, PRAD-.l, int-2, hst-1 and p 53 etc with lirikage to head and neck malignancy. The HLA gene association is the most convincing evidence for the role of genetics in the aetiology of nasopharyngeal cancer. EGFR looks to be a promising prognostic indicator as its interaction with the polypeptide epidermal growth factor stimulates proliferation of target cells.

Department of Otorhinolaryngology, Qilu Hospital of Shandong University, Jinan, Shandong, China.
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.
