Background: Paracoccidioidomycosis (PCM) is a neglected fungal infection with a high impact on the quality of life of the affected patients. The disease presents primary pulmonary involvement and systemic dissemination may occur. About 50% of the cases show oral involvement, and the factors that lead to this manifestation are not clear.
Objectives: The aim of this study was to evaluate the DNA methylation profile in PCM patients with oral lesions.
Material And Methods: Genomic DNA was extracted from whole blood of eighteen PCM patients, being ten with oral lesions and eight with no oral lesion. Analysis of methylation profile was performed using the technique of methylation-sensitive arbitrarily primed PCR (MS-AP-PCR). The sequences of recombinant plasmids obtained were evaluated according to parameters that define a CpG island, as well as their relative position in the known human genome genes and/or CpG islands.
Results: After DNA amplification, three different expressed bands were observed between the two groups, being found in the samples of patients with no oral manifestations. The cloned fragment in the plasmid showed similarity with a DNA sequence present in chromosome 20, next to the YTHDF1 gene. Other bands showed homology with intronic region in the genes RBPMS2 and DPH6 and no CpG island was identified.
Conclusions: DNA methylation was found in PCM patients with no oral lesion affecting the YTHDF1 gene. Further studies are necessary to elucidate to role of YTHDF1 gene in the oral PCM manifestations.

Introduction: The burden of severe asthma on patients, especially on those with concomitant chronic rhinosinusitis with nasal polyps (CRSwNP), is substantial. Treatment intensification with oral corticosteroids is a common strategy for managing severe asthma exacerbations; however, prolonged exposure to systemic corticosteroids is associated with multisystem toxicity. This study aimed to quantify the association between oral corticosteroid use and annual asthma-related costs in patients with severe asthma with or without CRSwNP.

Aims: Apical Periodontitis (AP) involves complex interactions between the root canal microbiome and the host immune response, with potential risk of local and systemic inflammatory burden, however there is no evidence available regarding correlation between microbiome and inflammatory marker levels. This study aims to identify the microbiome of saliva, intracanal and blood samples in AP subjects and investigate the correlation between intracanal and blood microbiomes with serum inflammatory biomarker levels, and salivary microbiomes with salivary inflammatory biomarker levels.
Methodology: Saliva, Intracanal and blood samples were collected from AP patients undergoing root canal retreatment.

We describe the utility of 'folic and folinic acid load tests' in the investigation of a 26-year-old woman with persistently low serum folate and moderate hyperhomocysteinaemia unresponsive to folic acid supplements. Serum folate, plasma 5-methyltetrahydrofolate (5-MTHF), red cell 5-MTHF and plasma total homocysteine at baseline, 2-h, 4-h and 2- or 4-days (if applicable) post administration of a large dose of oral folic acid, or oral or parenteral folinic acid were measured. The tests confirmed non-compliance but also suggested an unsuspected possible defect in the folate pathway based on differential response to folic versus folinic acid supplements.

Background: Sesame allergy (SA) is a growing concern because of its association with severe reactions and the limited knowledge of long-term outcomes.
Objective: This retrospective study aimed to identify the risk factors influencing persistent SA (PSA) in children to improve management and select suitable candidates for oral immunotherapy (OIT).
Methods: We analyzed the electronic medical records of 84 children with confirmed SA, as defined by consistent clinical reactions and immunoglobulin E (IgE)-mediated sensitization.
