Geographic tongue as a reaction-diffusion system.

Chaos 2021 Mar;31(3):033118

Department of Physics, The College of Wooster, Wooster, Ohio 44691, USA.

Geographic tongue or benign migratory glossitis is a condition of an unknown cause characterized by chronic lesions that slowly migrate across the surface of the tongue. The condition's characteristic wavefronts suggest that it can be modeled as a reaction-diffusion system. Here, we present a model for geographic tongue pattern evolution using reaction-diffusion equations applied to portions of spheroids and paraboloids that approximate a tongue shape. Read More

Virchows Arch 2021 Jan 19. Epub 2021 Jan 19.

Unidade Integrada de Patologia Especializada (UniPE), Postgraduate Program in Pathology, Pathological Anatomy Service of Hospital Universitário Antônio Pedro, Universidade Federal Fluminense, Niterói, RJ, 23033-900, Brazil.

Department of Stomatology, Oral Medicine Clinic, School of Dentistry, University of São Paulo, São Paulo, Brazil.

Oral mucosal lesions presenting as erythematous patches usually pose difficulties for a clinical diagnosis. They elicit an array of differential diagnosis that mainly includes oral candidosis, contact mucosal reaction, oral lichenoid lesion, oral psoriasiform, autoimmune disease, and, not to forget, secondary syphilis. In this present case, all those above-mentioned possibilities were ruled out, while secondary syphilis stood as the main diagnosis. Read More

Animals (Basel) 2020 Jul 1;10(7). Epub 2020 Jul 1.

Department of Psychology, University of Tennessee, Knoxville, TN 37996, USA.

Denning behavior has long remained the least observed aspect of bear behavior. During 2010-2013, we used webcams, microphones, the internet, and 14,602 h of archived video to document the denning behaviors of two adult wild black bears () as they gave birth and cared for four litters through six winters in northeastern Minnesota. Observations included types of dens, labor, pre-parturient genital swelling, birthing positions, post-partum vocalizations, mothers removing amniotic tissues and warming newborn cubs in sub-freezing temperatures, frequency of nursing, cubs establishing nipple order, yearlings suckling, the ingestion of snow and icicles, the ingestion of foot pads, urination and defecation in latrine areas, toilet-licking, eye opening, reciprocal tongue-licking, play, rapid eye movement (REM) sleep and possible dreaming, and reactions to wildlife intruders.

Oral rehabilitation in a patient with Jeune syndrome presenting with multiple teeth agenesis.

Spec Care Dentist 2020 Sep 3;40(5):493-497. Epub 2020 Jul 3.

Department of Dental Materials and Prosthodontics, School of Dentistry of Ribeirão Preto, University of São Paulo (USP), Ribeirão Preto, São Paulo, Brazil.

Jeune syndrome (JS) is a rare disease, with systemic manifestations, such as renal and hepatic insufficiency, retinal pigmentation, and respiratory insufficiency. Etiological factors have not been completely elucidated, but the molecular biology has contributed to the diagnosis and understanding of JS with DNA sequencing, showing the association among polymorphisms in different genes DYNC2H1 (MIM 603297) and TCTEX1D2 (MIM617353), which are the main genes associated with JS. There are a few reports on buccal findings in these patients; here, we present dental anomalies and clinical oral findings in a patient with JS, focusing on a multidisciplinary approach for rehabilitation.
