Children and Mothers' Preferences of Dentists’ Attire in Public Daycare Centers

According to the environment and appearance of the professional in the dental office, the child may have different emotional reactions. New designs and styles of clothing are emerging in the market and offered to health professionals. This study aimed to verify the preference of mothers and children from 3 to 6 years of age concerning dental attire. Material and Method. The sample had 621 preschoolers of both genders, age randomly selected in public daycare centers in 6 cities, covering the Brazil states of Tocantins, Goiás, Pará, and Bahia. The study was conducted with a child playful projective test and an interview questionnaire for the mothers. The results among children's preferences of dental attire from daycare centers in different cities showed a statistically significant correlation at the level of 5% (P < 0.0001). The mother’s preferences for attire showed a significant correlation at the level of 5 % (P = 0.0004). The children's preferences were for colorful attires, and their respective mothers prefer blue color. This selection has no cultural character nor for the family environment, as demonstrated in the various places the non-predominance of a single preference they mothers and their children. Preschool children were able to select their game options with this infant test

Chronic chagasic cardiopathy is the most severe form of the disease, characterized by lesions in the myocardium associated with inflammation and fibrosis which often evolve to progressive decrease of heart function. Chagas’ disease during aging may have specific aspects that require further studies. The aim of the study was to describe the relationship of angiogenesis and mast cell density with myocardial fibrosis in elderly patients with chronic Chagas' disease. To reach this goal we selected left ventricular fragments of autopsied patients at the Clinical Hospital, Federal University of Triangulo Mineiro. The samples were divided into four groups: elderly with chagasic cardiopathy - 6 (CC elderly); elderly without chagasic cardiopathy - 5 (SC elderly); Non-elderly with chagasic cardiopathy - 5 (no elderly CC); Non-elderly without chagasic cardiopathy - 5 (no elderly SC). Picrosirius red staining was performed for quantifying the percentage of collagen in common light and 10x magnification. Immunohistochemistry was performed to obtain the mast cell density, using antitriptase monoclonal antibody, and the density of blood vessels, using CD34 monoclonal antibody. The samples were evaluated under common light and at 40x magnification. The percentage of collagen was significantly higher in the elderly CC group compared to the other groups (p = 0.003). The density of mast cells was higher in elderly CC group, but no significant difference (p = 0.226). The density of blood vessels was lower in the elderly CC group and no significant difference (p = 0.224). Therefore, in elderly CC group there was more collagen, and also higher density of mast cells and lower density of blood vessels, although not significant, which are probably associated to the etiopathogenesis of myocardial lesions in chronic Chagas' disease during aging.Nas Américas milhões de pessoas são portadoras da doença de Chagas causada pelo Trypanosoma cruzi. A cardiopatia chagásica crônica é a forma mais grave da doença, caracterizada por lesões no miocárdio associadas a processo inflamatório e fibrose que muitas vezes evoluem para progressiva diminuição das funções cardíacas. A doença de Chagas durante o envelhecimento pode ter aspectos específicos que precisam ser mais claramente entendido. O objetivo do estudo foi descrever a relação da angiogênese e da densidade de mastócitos com a fibrose miocárdica em idosos portadores de cardiopatia chagásica crônica. Para tanto foram selecionados fragmentos do ventrículo esquerdo de pacientes autopsiados no Hospital das Clínicas da Universidade Federal do Triângulo Mineiro. Formou-se quatro grupos, idosos com cardiopatia chagásica – 6 (Idoso CC); idosos sem cardiopatia chagásica – 5 (Idoso SC); Não-idosos com cardiopatia chagásica – 5 (não idoso CC); Não-idosos sem cardiopatia chagásica - 5 (não idoso SC). Realizou-se a técnica de picrosirius para quantificação da porcentagem do colágeno sob luz comum e objetiva de 10x. A imunohistoquímica foi realizada para obtenção da densidade de mastócitos utilizando o anticorpo monoclonal antitriptase, e para a densidade de vasos sanguíneos o anticorpo monoclonal CD34, ambas foram avaliadas sob luz comum e objetiva de 40x. A porcentagem de colágeno foi significativamente maior no grupo de idosos CC, quando comparada aos outros grupos (p=0,003). A densidade de mastócitos foi maior no grupo de idosos CC, mas sem diferença significativa (p=0,226). A densidade de vasos sanguíneos foi menor no grupo de idosos CC e sem diferença significativa (p=0,224). Portanto, foi verificada no grupo de idosos CC maior quantidade de colágeno, e ainda, maior densidade de mastócitos e menor densidade de vasos sanguíneos, embora não significativa, que provavelmente estão relacionados com a etiopatogênese das lesões miocárdicas na cardiopatia chagásica crônica durante o envelhecimento
