Emotional assessment of patients with oral lichen planus

Oral lichen planus is a chronic immune‐mediated disease with an estimated prevalence of 0.5–2.5% in the general population. Patients with oral lichen planus are often emotionally unstable and anxious and may develop concomitant systemic disorders. The objective of this study was to evaluate emotional characteristics of patients with oral lichen planus.

Is DNA ploidy related to smoking

BACKGROUND In the oral cavity, genomic instability is caused by long-term exposure to carcinogens. The aim of this study was to evaluate the relationship between smoking and DNA ploidy. METHODS Cytological material was obtained from patients participating in the Outpatient Smoking Treatment Program of the Heart Institute (INCOR-HCFMUSP), and of the Discipline of Oral Medicine (ICT-UNESP). The inclusion criteria for all groups were the absence of a history of malignant tumors, absence of clinical signs of changes in the selected area, and alcohol consumption of less than 3 units per week. Group 1:30 smokers before smoking cessation treatment; Group 2:30 non-smokers; Group 3:30 ex-smokers abstinent for at least 1 year. Cytological smears were collected from the floor of the mouth and border of the tongue and stained by Feulgen. Aneuploidy was evaluated using the ACIS® III system. RESULTS The Kruskal-Wallis test showed no statistically significant difference (P = .4383) between the groups studied. No association between tobacco consumption and aneuploidy was observed in group 1 (P = 1) or group 2 (P = .68; Fishers exact test). CONCLUSION Smoking was not associated with changes in DNA content or the incidence of aneuploidy in normal oral mucosa.

O processo de alfabetização: da pré-história da escrita a escrita simbólica

This article focuses on literacy in the light of Historical-Cultural Psychology, establishing relationships between it and the cultural development of the psyche, highlighting the links between speech and writing. It aims to present elements that corroborate the understanding of the psychic processes that mediate the learning of the writing exploring the cultural traffic that advances from the primeval graphic expressions, denominated by Alexander Romanovich Luria like “prehistory of the writing”, to the symbolic writing. Since the legacy of this author confers centrality to the early development of writing, we have identified in the historical-cultural literature the existence of a hiatus in the treatment, specifically, of the transition between prehistory and symbolic writing, since it leads us the search for clarifications about it. Based on the historical-dialectical materialist method, we adopted as research procedures: the conceptual analysis of the bibliographic references adopted and the analysis of empirical data derived from the field records of two literacy teachers,
