Geographic tongue (GT) is a benign inflammatory disorder of unknown etiology. Epidemiology and histopathology in previous studies found that generalized pustular psoriasis (GPP) is a factor associated with GT, but the molecular mechanism remains obscure. To investigate the mechanism of GT, with and without GPP, three cohorts were recruited to conduct genotyping of IL36RN, which is the causative gene of GPP. In a family spanning three generations and diagnosed with only GT ("GT alone"), GT was caused by the c...

In this study we developed a genome-based method for detecting Staphylococcus aureus subtypes from metagenome shotgun sequence data. We used a binomial mixture model and the coverage counts at >100,000 known S. aureus SNP (single nucleotide polymorphism) sites derived from prior comparative genomic analysis to estimate the proportion of 40 subtypes in metagenome samples. We were able to obtain >87% sensitivity and >94% specificity at 0.025X coverage for S. aureus. We found that 321 and 149 metagenome samples from the Human Microbiome Project and metaSUB analysis of the New York City subway, respectively, contained S...

The interesting history of papillomavirus (PV) research has been reviewed before. The history of human papillomavirus (HPV) in head and neck region starts in 1901 when the contagious transmission of warty lesions into the mouth via oral sex was described, although the confirmation of their viral etiology had to wait until 1907. Ullman was the first to associate the human wart virus with laryngeal warts. Parsons and Kidd described the natural history of oral PV infections in rabbits already in 1942, but these findings were corroborated in humans only recently...

The oral mucosa including the lips is constantly exposed to several noxious stimuli, irritants and allergens. However, oral contact pathologies are not frequently seen because of the relative resistance of the oral mucosa to irritant agents and allergens due to anatomical and physiological factors. The spectrum of signs and symptoms of oral contact allergies (OCA) is broad and a large number of condition can be the clinical expression of OCA such as allergic contact stomatitis, allergic contact cheilitis, geographic tongue, oral lichenoid reactions, burning mouth syndrome...

Geographic tongue is a chronic, inflammatory, and immune-mediated oral lesion of unknown etiology. It is characterized by serpiginous white areas around the atrophic mucosa, which alternation between activity, remission and reactivation at various locations gave the names benign migratory glossitis and wandering rash of the tongue. Psoriasis is a chronic inflammatory disease with frequent cutaneous involvement and an immunogenetic basis of great importance in clinical practice. The association between geographic tongue and psoriasis has been demonstrated in various studies, based on observation of its fundamental lesions, microscopic similarity between the two conditions and the presence of a common genetic marker, human leukocyte antigen (HLA) HLA-C*06...

OBJECTIVES: Geographic tongue or migratory glossitis is an inflammatory disorder with unknown etiology. Considering the accompanied burning pain, taste dysfunction, and lack of definite cure, it is important to treat this condition symptomatically. The objective of the current study was to compare the efficacy of a combination of 0.05% retinoic acid and 0.1% triamcinolone acetonide with that of triamcinolone acetonide alone for treatment of symptomatic geographic tongue. MATERIALS AND METHODS: This randomized controlled double-blind clinical trial was performed on 28 patients with symptomatic geographic tongue, who were referred to two dental clinics...

INTRODUCTION: Scurvy, or "Barlow's disease", is a widely described disease involving cutaneous and mucosal lesions resulting from vitamin C deficiency. Herein, we report a case of scurvy in a 48-year-old woman that was unusual in its atypical cutaneous-mucosal presentation as well as its association with anorexia nervosa. PATIENTS AND METHODS: A 48-year-old woman treated for depression for several years was admitted to hospital for her impaired general state of health...

This study investigated the cause of the mortality of piglets with cutaneous, enteric and neurological disorders from seven pig farms located in different geographical regions of Brazil. Twelve 1- to 5-day-old piglets were submitted for pathological evaluation. The principal gross findings included faint rib impressions on the pleural surface of the lungs (n = 9), diphtheritic glossitis (n = 6) and ulcerative lesions at the coronary band (n = 5). Histopathology revealed interstitial pneumonia (n = 12), myocarditis (n = 6), diphtheritic glossitis (n = 3), encephalitis (n = 3) and atrophy of intestinal villi with vacuolation of the superficial epithelial cells (n = 6)...

OBJECTIVE: To assess the association between the prevalence of tongue cyst-positive and antigen-positive pigs across different settings in Africa, to evaluate whether examining pigs for cysts could be used as a rapid surveillance tool for identifying geographical areas with a higher probability of high transmission of cysticercosis. METHODS: Published data were collated from 26 study sites across Africa that reported the prevalence of porcine cysticercosis by both lingual and serological examinations...

Melkersson Rosenthal syndrome is a very infrequent disease of unknown etiology, chronic and progressive course, with neurocutaneous disease that affects the orofacial innervation and mucocutaneous tissues with non-caseating granulomatous infiltration. Clinically, it is characterized by the diagnostic triad: recurrent edema of lips and/or face; recurrent and alternating acute peripheral facial paralysis and scrotal or geographic tongue. The condition generally presents as oligosymptomatic or monosymptomatic form...

BACKGROUNG: The aim of the present study was to determine the prevalence of oral mucosal non-malignant lesions in the Sicilian population. In addition, we evaluated the association between each oral lesion and its risk factors. METHODS: This study analyzed a total of 2539 consecutive patients, attending the Department of Surgical, Oncological and Stomatological Disciplines of Palermo University, who were examined for the presence of various oral lesions during the period from January 2012 and February 2015...

Parasites of the genus Trichinella are cosmopolitan nematodes infecting primarily wild animals, which represent the main reservoirs of these zoonotic pathogens. To investigate the transmission patterns of Trichinella spp. from wild to domestic animals and to humans and for the risk assessment of these parasites in a geographical area, it is important to know the number of possible transmission events deriving from carcasses of infected hosts. For this purpose, the evaluation of the larval biomass in reservoir hosts is needed...

BACKGROUND: Geographic tongue (GT) is a benign inflammatory condition usually involving the dorsal surface and lateral borders of the tongue. Numerous etiological factors of GT have been suggested, including immunological factors; genetic; atopic or allergic predisposition; emotional stress; and hormonal disturbances. GT may also coexist as one of the possible manifestations of celiac disease (CD). Therefore, the aim of this study was to investigate the prevalence of CD, positive serologic tests for CD screening, and HLA-DQ presence in patients with GT...

Practitioners and policy-makers need information about the relative frequency of dental anomalies among children in their region. This study investigated the prevalence of different oral anomalies among schoolchildren in Sana'a city, Yemen. A sample of 1000 private and public schoolchildren aged 4-12 years were examined by the same examiner using disposable tongue blades. The total prevalence of oral anomalies was 15.1%, most commonly in boys (male:female ratio 3.2:1) aged 7-12 years. The most prevalent dental anomaly related to hard tissues was tooth hypoplasia (2...

BACKGROUND: Oral lichen Planus (OLP) is a chronic inflammatory disease involving skin and mucous membranes. Its etiology is still uncertain whilst an autoimmune mechanism is known to be implicated. OLP is commonly considered a geriatric disease and gender differences in prevalence are clear, whereby females are generally more frequently affected than males more often during the 5th and 6th decades of life. Lesions are symmetrical and bilateral and the buccal mucosa is frequently involved...
