Argentoleon irrigatus (Gerstaecker), is a common antlion species, but with sparse figures and incomplete location records in the literature, whose genitalia and larvae remained undescribed. Herein, the adults are redescribed and immatures (larvae and pupa) are described for the first time, providing images of internal and external characters, including both male and female genitalia. The examination and illustration of these characters allowed us to better understand the position and the limits of the genus Argentoleon Stange, within the tribe Brachynemurini, including the differentiation of the larval stages of the closely related genus Austroleon Banks.

Article Synopsis
  • The study analyzes the characteristics of oral reactions to injectable soft tissue fillers, focusing on 151 patients, predominantly females averaging 54.9 years old.
  • Most reactions occurred about 20.4 months after injection, often presenting as painless nodules in the lips, with silicone and polymethylmetacrylate being the most common fillers used.
  • Key findings showed differences in reaction patterns based on the type of filler and highlighted the importance for clinicians to recognize these potential reactions when assessing asymptomatic nodules in older female patients.

Microplastics (MPs) are increasingly widespread in the environment, which raises questions about their potential effects at different biological levels. It is essential to assess the impacts on biodiversity, and it is also crucial to understand whether the presence of MPs can interfere with the biological traits of species of relevance in public health. Considering that the life-history traits of mosquitoes, such as size and the wingbeat frequency (WBF), are related to its vector competence, here, we study the effects of 10 particles L (as expected concentration of MPs on the environment, using the polyethylene type) on WBF, as well as wing morphology, testing the Culicidae species found across all continents, Aedes aegypti, as an indicator.

COVID-19, a respiratory illness with a global impact on millions, has recently been linked to manifestations affecting various bodily systems, including the oral cavity. Studies highlight oral issues, like ulcers, blisters, and white patches, alongside olfactory and gustatory dysfunction, influencing an individual's quality of life. In this context, our study aimed to assess the frequency of oral lesions, olfactory and gustatory disorders, and xerostomia resulting from COVID-19.

Objective: To report the case of a girl presenting a severe phenotype of mandibuloacral dysplasia type A (MADA) characterized by prominent osteolytic changes and ectodermal defects, associated with a rare homozygous LMNA missense mutation (c.1579C>T).

Case Description: A 6-year-old girl was evaluated during hospitalization exhibiting the following dysmorphic signs: subtotal alopecia, dysmorphic facies with prominent eyes, marked micrognathia and retrognathia, small beaked nose, teeth crowding and thin lips, generalized lipodystrophy, narrow and sloping shoulders, generalized joint stiffness and bone reabsorption in the terminal phalanges.

The aim of this systematic review was to describe the clinical and genetic features of syndromes showing oligodontia as a sign. The review was performed according to the PRISMA 2020 checklist guidelines, and the search was conducted using PubMed, Scopus, Lilacs, Web of science, Livivo, and EMBASE and supplemented by a gray literature search on Google Scholar and ProQuest, applying key terms relevant to the research questions. The systematic review identified 47 types of syndromes in 83 studies, and the most common was hypohidrotic ectodermal dysplasia, which was reported in 24 patients in 22 studies.

This study aimed to compare factors that influence perception of quality of life (QoL) in patients scheduled for orthognathic surgery. This was a cross-sectional study with 91 participants from two universities in Curitiba. The orthognathic quality of life questionnaire (OQLQ) was used to assess patients' perceptions of their QoL.

Purpose: The purpose of this study was to measure and compare coronectomy versus extraction in patients at increased risk for inferior alveolar nerve (IAN) injuries associated with third molar removal in terms of IAN injury and other complications.

Methods: The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist. We conducted a comprehensive literature search across six databases and the gray literature from July 15 to August 01, 2022.

Background: Nonsyndromic orofacial clefts (NSOC) are the craniofacial most common congenital malformations. There are evidences that the nonsyndromic cleft palate (NSCP) development differs from other NSOC. However, most of the publications treat NSCP without considering that information.

Objective: The study evaluated the association of tag-SNPs and SNP-SNP interactions involving genes active by BMP4 pathway during craniofacial development in the susceptibility of nonsyndromic orofacial clefts (NSOC) in the Brazilian population.

Design: Case-control study.

Setting: Brazilian Oral Cleft Group.

Background: The expression of heat-shock protein 47 (HSP47) has been linked to collagen synthesis control and implicated in fibrotic disorders, but more recent studies have demonstrated its role in solid tumors. In this study, we explored the prognostic impact of HSP47 in oral squamous cell carcinomas (OSCC) and determined the in vitro effects of its loss-of-function on viability, proliferation, migration, invasion, and resistance to cisplatin of OSCC cells.

Methods: The HSP47 expression in tumor samples was assessed by immunohistochemistry in two independent cohorts totaling 339 patients with OSCC, and protein levels were associated with clinicopathological features and survival outcomes.

Article Synopsis
  • The study explores the connection between hypertrichosis (excessive hair growth) and various dental anomalies, identifying 39 genetic syndromes that may exhibit these traits through searches in genetic databases.
  • Dental agenesis (missing teeth) is the most common dental issue found in these syndromes, present in about 41% of the cases analyzed, with causative genes identified in 33 of the syndromes.
  • An integrative analysis revealed significant biological processes related to chromosomal organization and nucleosome disassembly, suggesting potential pathways involved in these conditions, which could help in diagnosing the associated syndromes.

Article Synopsis
  • This study focused on examining the prevalence of oral lesions in HIV patients and how these lesions relate to factors like CD4 count, viral load, and antiretroviral therapy.
  • Among the 161 patients studied, 58.39% presented with oral lesions, with periodontal disease being the most common, alongside fewer cases of hyperpigmentation and candidiasis.
  • The research found no significant links between the presence of oral lesions and key HIV indicators like CD4 count or viral load, but longer treatment duration correlated with reduced severity of periodontal disease.

Objective: Although there have been remarkable achievements in the molecular landscape of oral squamous cell carcinoma (OSCC) in recent years, bringing advances in the understanding of its pathogenesis, development and progression, little has been applied in the prognosis and choosing the optimal treatment. In this study, we explored the influence of the stress induced phosphoprotein 1 (STIP1), which is frequently reported to be highly expressed in many cancers, in OSCCs.

Methods: STIP1 expression was assessed in the TCGA database and in two independent cohorts by immunohistochemistry.

Associations of (cysteine-rich secretory protein LCCL domain containing 2) and genes belonging to its activation pathway, including (Fos proto-oncogene), (caspase 8) and with nonsyndromic orofacial cleft risk, have been reported, but the results are yet unclear. The aim of this study was to evaluate single nucleotide polymorphisms (SNPs) in , and and to determine their SNP-SNP interactions with variants in the risk of nonsyndromic cleft lip with or without cleft palate (NSCL±P) in the Brazilian population. The SNPs rs1046117 (), rs3769825 () and rs243836 () were genotyped using TaqMan allelic discrimination assays in a case-control sample containing 801 NSCL±P patients (233 nonsyndromic cleft lip only (NSCLO) and 568 nonsyndromic cleft lip and palate (NSCLP)) and 881 healthy controls via logistic regression analysis adjusted for the effects of sex and genomic ancestry proportions with a multiple comparison value set at ≤0.
