The recommendations gathered from a workshop with expert professors on the challenges in OPMD/OC teaching were reported.

Oral management of children/adolescents with ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome: A scoping review.

Aims: EEC is a rare syndrome characterized by the triad of ectrodactyly, ectodermal dysplasia, and orofacial clefting, along with other clinical manifestations mainly in hair, skin, and teeth. The present paper aimed to perform a scoping review to collect the most relevant studies and focused on the diagnosis and oral management of EEC syndrome in the pediatric dental setting. This review also pretended to make recommendations and map the gaps in this clinical topic.

Do fluoroquinolone agents produce therapeutic benefits or harmful effects in patients with periodontitis? A systematic review and meta-analysis.

The adjunctive use of fluoroquinolone (FQ) agents in patients with periodontitis produces contradictory results. There has been no meta-analysis performed based on the evaluations of FQ use that would enable making appropriate clinical decisions. Our study aimed to evaluate, via a systematic review and metaanalysis conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines, the clinical benefits, antimicrobial effects and safety profiles of the FQ agents administered to periodontitis patients under a conventional treatment regime.

Effect of Five Commercial Probiotic Formulations on Candida Albicans Growth: In Vitro Study.

Purpose: The objective was to evaluate the antagonistic effect of Lactobacillus and Bifidobacterium recovered from five commercial probiotics on the growth of C. albicans.

Study Design: The Lactobacillus and Bifidobacterium strains of five commercial probiotics were recovered and grown: Probio Hp+®, ProBiseis®, Lactipan®, Liolactil®, and Lacteol Fort®; 50 mg of each was hydrated and grown in Lactobacilli MRS (De Man, Rogosa and Sharpe) broth and incubated at 37°C with stirring (120 RPM) for 24 hours.

Effect of cytomegalovirus infection and leukocyte immunoglobulin like receptor B1 polymorphisms on receptor expression in peripheral blood mononuclear cells.

Leukocyte immunoglobulin like receptor B1 (LILRB1) plays a significant role in a number of infectious, autoimmune, cardiovascular, and oncologic disorders. LILRB1 expression varies between individuals and may be associated with polymorphisms on the regulatory region of the LILRB1 gene, as well as to previous cytomegalovirus infection. In this study, the contribution of these two factors to LILRB1 expression in peripheral blood mononuclear cells of healthy young adults was analyzed.

Tau Protein in Oral Mucosa and Cognitive State: A Cross-sectional Study.

Neurodegenerative diseases are characterized by the presence of abnormal aggregates of proteins in brain tissue. Among them, the presence of aggregates of phosphorylated Tau protein (p-Tau) is the hallmark of Alzheimer's disease (AD) and other major neurodegenerative disorders such as corticobasal degeneration and frontotemporal dementia among others. Although Tau protein has previously been assumed to be exclusive to the central nervous system, it is also found in peripheral tissues.

The essential oil of Allium sativum as an alternative agent against Candida isolated from dental prostheses.

Background: The colonization of the surfaces of dental prostheses by Candida albicans is associated with the development of denture stomatitis. In this context, the use of fluconazole has been proposed, but its disadvantage is microbial resistance. Meanwhile, the oil of Allium sativum has shown an effect in controlling biofilm formation by C.

Measurement of levofloxacin in human plasma samples for a reliable and accessible drug monitoring.

Objectives: Levofloxacin monitoring is recommended to obtain clinical cure and low incidence of antimicrobial resistance. During the monitoring procedure, levofloxacin should be measured in plasma samples and several assays are reported for this purpose. However, those methods do not have all of the characteristics for an accessible and reliable drug monitoring.

Orosomucoid-1 Expression in Ameloblastoma Variants.

Odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. Ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. We previously described orosomucoid-1 protein expression in odontogenic myxomas.

Oral Candida isolates and fluconazole susceptibility patterns in older Mexican women.

Objectives: To assess the epidemiologic and microbiologic profile and in vitro fluconazole susceptibility of yeasts isolated from the oral mucosa colonization/infection of elderly patients.

Background: It has been reported that in older adults increases the oral colonization by Candida particularly C. non-albicans, showing a decreased response to fluconazole, which increases the risk of recalcitrant local and disseminated candidiasis.

Oral presentation of 10 patients with Cowden syndrome.

Cowden syndrome (CS) is an autosomal dominant genodermatosis that frequently affects several tissues with hamartomatous growth. The oral cavity is quite commonly involved with papillomatous lesions, which can be crucial to early diagnosis of this disease. In this series, 10 patients with a great diversity of manifestations associated with CS are presented, in whom oral papillomatosis was a constant and relevant finding to establish the diagnosis of CS.

Killer-cell immunoglobulin-like receptors (KIR) in severe A (H1N1) 2009 influenza infections.

Introduction of a novel influenza virus into the human population leads to the occurrence of pandemic events, such as the one caused by pandemic influenza A (H1N1) 2009 virus. The severity of infections caused by this virus in young adults was greater than that observed in patients with seasonal influenza. Fatal cases have been associated with an abnormal innate, proinflammatory immune response.
