Background: The submental island flap (SIF) is a pedicled flap based upon the submental artery and vein. Its utility in reconstruction following ablative head and neck procedures has been applied to various subsites including skin, lip, buccal mucosa, retromolar trigone, parotidectomy defects, and tongue. We review our experience using the SIF for reconstruction following tumor ablation. Methods: This prospective case series with medical record review includes consecutive patients undergoing SIF reconstruction following ablative surgery for malignancy at a single tertiary care facility between November 2014 and November 2016...

BACKGROUND: Periodontitis is a major risk factor of systemic diseases with inflammatory etiology. Numerous studies have established the connection between periodontal condition and diabetes, but there are no reports in the literature on the relationship between periodontitis and other pancreas conditions. The activity of pancreatic enzymes is an important parameter of pancreatic damage, and is also a diagnostic marker of acute and chronic pancreatitis, and the bleeding index determines the periodontitis activity...

Nicotine, obtained from tobacco leaves, has been used to promote the cessation of smoking and reduce the risk of COPD and lung cancer. Incorporating the active in lipid nanoparticles is an effective tool to minimize its irritation potential and to use the particles as intermediate to produce final products. However, as a hydrophilic active, it is a challenge to prepare nicotine loaded lipid nanoparticles with high drug loading. In this study, lipid-drug-conjugates (LDC) were formed by nicotine and different fatty acids to enable the production of sufficiently loaded nicotine lipid nanoparticles...

Head and neck squamous cell carcinomas (HNSCC) are a diverse group of tumor types, including neoplasia of the paranasal sinuses, oral cavity, trachea, pharynx and larynx. Laryngeal cancer is the most common type of HNSCC. The proline-rich 4 (PRR4) protein is synthesized in the acinar cells of human lacrimal glands. Previous studies have demonstrated that PRR4 may function as an antimicrobial protein protecting the ocular surface and the oral cavity. In order to determine differentially expressed genes (DEGs) in laryngeal tumors, a GeneFishing Assay was performed; 27 DEGs were identified...

BACKGROUND: The increasing incidence of oropharyngeal squamous cell cancer (OPSCC) is well established. However, up-to-date incidence estimates and trends for head and neck squamous cell cancers (HNSCCs) overall, including major anatomic sites, and nonoropharyngeal (non-OP) HNSCCs by sex, race, and age in the United States are not well described. METHODS: A retrospective analysis of incident HNSCCs during 1992 through 2014 using the Surveillance, Epidemiology, and End Results database was performed to evaluate the incidence of HNSCCs overall, OPSCC, and non-OP HNSCC (those of the larynx, oral cavity, hypopharynx, nasopharynx, and nasal cavity)...

PURPOSE OF REVIEW: The quantity of tissue removed during an oncologic surgical procedure is not standardized and there are numerous reports of local recurrence despite histologically adequate resection margins. The oral cavity is one of the sites in the head and neck with high chances of recurrence following negative margins. To address this need, this article reviews the recent applications of Dynamic Optical Contrast Imaging (DOCI) towards both oral screening and the intraoperative evaluation of tumor margins in head and neck surgery...

Metastasis to the sublingual lymph nodes is very rare in oral cavity cancers. We present an early-stage floor of the mouth (FOM) cancer case with metastasis to the sublingual lymph node. Even though the rate of metastatic sublingual lymph nodes is low, the uncommon presence of sublingual lymph node metastasis in an early-stage FOM cancer case raises the question of routine FOM dissection. Further anatomic and pathologic studies addressing the rate and pattern of sublingual lymph node metastasis are warranted...

Metallic biomaterials in the oral cavity are exposed to many factors such as saliva, bacterial microflora, food, temperature fluctuations, and mechanical forces. Extreme conditions present in the oral cavity affect biomaterial exploitation and significantly reduce its biofunctionality, limiting the time of exploitation stability. We mainly refer to friction, corrosion, and biocorrosion processes. Saliva plays an important role and is responsible for lubrication and biofilm formation as a transporter of nutrients for microorganisms...

Smokeless tobacco (SLT) products are consumed by millions of people in over 130 countries around the world. Consumption of SLT has been estimated to cause a number of diseases accounting to more than 0.65 million deaths per year. There is sufficient epidemiological evidence on the association of SLT products with nicotine addiction, cancers of oral cavity and digestive systems but there is a lack of understanding of the role of toxic chemicals in these diseases. We provide the first comprehensive in-silico analysis of chemical compounds present in different SLT products used worldwide...

This paper provides a review of various image analysis approaches that have been previously used for recognition of dysplasia in images of the epithelium of the oral cavity. This domain has become especially admissible with the uncovering of the importance of image analysis which can probably be an aid to subjective diagnosis by histopathologists. Oral malignancy is a rampant form of cancer found among people of the Indian subcontinent due to various deleterious habits like consumption of tobacco, areca nut, betel leaf etc...
