Stomatitis is an inflammation of the oral mucosa that can affect the tongue, gums, inner cheeks, palate, and lips, causing painful sores that make simple tasks like eating, drinking, and speaking difficult. According to otolaryngologist Dr. Cleonice Hirata, from Hospital Paulista, the term does not refer to a specific disease, but rather to an inflammatory process with several possible origins, including viral, fungal, and bacterial infections, trauma from bites, orthodontic appliances, or poorly fitted dentures, as well as allergies, autoimmune diseases, tumors, and nutritional deficiencies.
The last partial lunar eclipse of the year offers today an unmissable opportunity for early risers to observe the Moon plunge into Earth's shadow, in a phenomenon that promises to be a spectacle in the night sky. For those who cannot wake up during the early morning hours or don't have the conditions to see the event directly, several online broadcasts are available that allow following the eclipse from anywhere.
Days after the largest solar eclipse of the century in Portugal, it is now the turn of a lunar eclipse, although not total in the country, reaching a maximum of 83%. The article debunks seven popular myths about lunar eclipses, including the belief that they are signs of bad omens, unfounded theories about effects on pregnancy and babies, and the legend of a mythological jaguar. It explains that a lunar eclipse occurs when the Earth positions itself between the Sun and the Moon, and unlike a solar eclipse, it can be observed with the naked eye. The phenomenon will be visible in Portugal between 2:30 AM and 7:10 AM, with its peak around 5:10 AM.
Portuguese researchers from the GeoBioTec center at Nova University of Lisbon and the Dom Luiz Institute concluded, through theoretical models, that energy storage in porous rocks located at depth can reach capacities sufficient to supply a small city. This discovery represents a significant advance in the field of renewable energies and geological energy storage.
Dentist Andréa Melo explains a groundbreaking Brazilian research conducted by the Headache Center Brasil, presented at the 22nd Congress of the International Headache Society, which identified a high prevalence of awake bruxism in patients with chronic migraine. The study, conducted using surface electromyography, showed that both conditions share the same neurological mechanism: hyperactivation of the trigeminal nerve, which runs through the facial muscles. Melo's clinical observation, which she has noted for years in patients referred by neurologists, now has scientific backing.
