CKS1B is a member of the highly conserved cyclin kinase subunit 1 (CKS1) protein family which interacts with cyclin-dependent kinases and plays a critical role in cell cycle progression. In oral squamous cell carcinoma (OSCC), as in other malignancies, CKS1B overexpression has been correlated with reduced survival. To our knowledge, no studies evaluating the genetic status of CKS1B gene in OSCC...

OBJECTIVES/HYPOTHESIS To assess the efficacy of laser therapy for the management of premalignant oral lesions. STUDY DESIGN The study group consisted of seventy consecutive laser-treated patients with oral leukoplakia. The microscopic diagnosis included idiopathic focal keratosis, dysplasias of all grades, and verrucous hyperplasia (proliferative verrucous leukoplakia). Thirty-nine patients h...

Introduction: Verrucous carcinoma is one of squamous cell in the oral cavity which can caused by smoking, alcohol consumption, HPV etc. mimick as pre cancer lesion such leukoplakia, so that early detection mandatory. Vital staining be done toluidine blue, but it reported toxic organ. Methylene blue had similar chemical structure and exhibited physicochemical properties to blue.The aim this case...

Lipid peroxidation induced by reactive oxygen species (ROS) is involved in the pathogenesis of malignancy. Overall, lipid peroxidation levels are indicated by malondialdehyde (MDA), which is the most frequently used biomarker to detect oxidative changes. Antioxidant defense systems such as glutathione (GSH) limit cell injury induced by ROS. Therefore, MDA and GSH can be used to monitor oxidativ...

OBJECTIVE To document the prevalence, age and gender distribution of oral lesions in HIV infected adults and the influence of highly active antiretroviral therapy and correlate them to the immune status of the patients. MATERIALS AND METHODS Oral lesions were diagnosed by a detailed physical examination by trained and calibrated examiners according to the case definitions established by the O...

The efficacies of CO2 laser and conventional laryngeal microsurgery for vocal cord benign (vocal cord polyp) and precancerous (vocal cord leukoplakia) lesions were compared. Patients with bilateral vocal cord polyps (n = 60) and leukoplakia (n = 30) were divided randomly into two groups. One group was treated with throat microsurgical instruments and underwent routine lesion resection (conventi...

The blue-green microalgae Spirulina, used in daily diets of natives in Africa and America, have been found to be a rich natural source of proteins, carotenoids, and other micronutrients. Experimental studies in animal models have demonstrated an inhibitory effect of Spirulina algae on oral carcinogenesis. Studies among preschool children in India have demonstrated Spirulina fusiformis (SF) to b...

Leukoplakia is the most common potentially malignant disorder of the oral mucosa. The prevalence is approximately 1% while the annual malignant transformation ranges from 2% to 3%. At present, there are no reliable clinicopathological or molecular predicting factors of malignant transformation that can be used in an individual patient and such event can not truly be prevented. Furthermore, foll...

OBJECTIVE To review the epidemiology, etiology, diagnosis, management, and prognosis of the most common, potentially lethal, lip lesions: leukoplakia, actinic cheilitis, and squamous cell carcinoma (SCC). QUALITY OF EVIDENCE MEDLINE: was searched from 1966 to 2002 for English-language articles on prevalence of lip lesions. No articles for a family physician audience were found. MEDLINE was sear...
