Squamous Cell Carcinomas of the Sinonasal Region and Temporal Bone Diagnosed After Recurrences: A Report of Two Patients.

squamous cell carcinoma is a recently recognized entity characterized by a non-viral-related non-keratinizing squamous cell carcinoma with chromosomal rearrangement between on 6p22.3 and on Xq28. This neoplasm is associated with an aggressive clinical behavior, particularly regarding local recurrences and distant metastases even with its deceptively bland histomorphology.

Middle ear ventilation tubes and water precautions: A survey of otolaryngologists and pediatricians on their recommendations.

Introduction. Middle-ear ventilation tubes are commonly placed in pediatric patients because of the high frequency of otitis media. Although avoidance of water activity has been recommended to prevent otorrhea, studies indicate that exposure to water does not increase these episodes.

d-Limonene inhibits cytokines and chemokines expression by regulating NF-kappaB and STAT in HaCat cells and DNCB-induced atopic dermatitis in BALB/c mice.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by itching and redness, affecting individuals of all ages and significantly impairing their quality of life. The prevalence of AD is rising, posing serious health concern. Relief of itching is a primary treatment objective; however, steroid treatments can lead to adverse effects, including skin barrier thinning.

Association between the gene polymorphism-determined earwax properties and external auditory canal microbiota in healthy adults.

Unlabelled: The concept of genome-microbiome interactions, in which the microenvironment determined by host genetic polymorphisms regulates the local microbiota, is important in the pathogenesis of human disease. In otolaryngology, the resident bacterial microbiota is reportedly altered in non-infectious ear diseases, such as otitis media pearls and exudative otitis media. We hypothesized that a single-nucleotide polymorphism in the ATP-binding cassette sub-family C member 11 () gene, which determines earwax properties, regulates the ear canal microbiota.

Outer hair cells stir cochlear fluids.

We hypothesized that active outer hair cells drive cochlear fluid circulation. The hypothesis was tested by delivering the neurotoxin, kainic acid, to the intact round window of young gerbil cochleae while monitoring auditory responses in the cochlear nucleus. Sounds presented at a modest level significantly expedited kainic acid delivery.

Body Temperature Regulation in Domestic Dogs After Agility Trials: The Effects of Season, Training, Body Characteristics, Age, and Genetics.

An animal's body mass is said to be indirectly related to its rate of heat loss; that is, smaller animals with higher surface area to volume tend to lose heat faster than larger animals. Thus, thermoregulation should be related to body size, however, generalizable patterns are still unclear. Domestic dogs are a diverse species of endothermic mammals, including a 44-fold difference in body size.
