Factors associated with oral biofilm in ICU patients with infectious diseases / Fatores associados à presença de biofilme oral em pacientes internados na UTI

Introduction: Hospitalization may cause a decline in oral health and affect the entire body. The intensive care unit (ICU) may be a favorable environment for oral biofilm to accumulate in critically ill patients. Objective: To identify factors associated with oral biofilm in ICU patients in a hospital for infectious diseases. Method: This was a retrospective, descriptive and inferential study with a quantitative approach. Data were collected from 178 medical records of patients from January 2012 to July 2015. Biofilm presence was assessed according to the Greene and Vermillion index. Potential influential factors were analyzed by logistic regression. Result: Among ICU patients, 69.1% were men, 60.7% had acquired immune deficiency (AIDS), 66.3% were ward patients, 50.6% were intubated, and 50.0% were sedated. The oral elements of the patients were mostly normal. The following characteristics were significantly associated with oral biofilm: changes in the lips, gums, cheeks, and palates and bleeding. Patients from the ward had a lower risk of biofilm. Conclusion: Increased oral biofilm accumulation was observed in patients with oral changes, and patient origin was associated with the presence of biofilm.

Introdução: A hospitalização pode provocar deterioração da saúde bucal, repercutindo em todo o corpo. A UTI pode ser um ambiente favorável ao acúmulo de biofilme oral em pacientes críticos. Objetivo: Identificar fatores associados à presença do biofilme em pacientes da UTI de um hospital de doenças infectocontagiosas. Método: Estudo retrospectivo, descritivo e inferencial, com abordagem quantitativa. Os dados foram obtidos em prontuários de pacientes da UTI, de janeiro de 2012 a julho de 2015. O biofilme foi avaliado de acordo com o índice de Greene e Vermillion. Os fatores influentes foram analisados por regressão logística. Resultado: Entre os pacientes da UTI, 69,1% eram homens, 60,7% pacientes com AIDS, 66,3% pacientes na enfermaria, 50,6% intubados e 50,0% sedados. Seus elementos orais eram na maioria normais. As seguintes características foram significativamente associadas a biofilmes orais: alterações orais nos lábios, gengivas, bochechas e palatos e sangramento. Pacientes da enfermaria apresentaram menor risco de apresentar biofilmes. Conclusão: o aumento do acúmulo de biofilme oral foi observado em pacientes com alterações na boca e a procedência do paciente foi associada à presença de biofilme.

Profile of Hospitalizations and Deaths from Craniofacial Fractures in Brazilian Children and Adolescents: An Ecological Study

Objective: To characterize the profile of hospitalizations and deaths related to craniofacial fractures in Brazilian children and adolescents. Material and Methods: This is an ecological cross-sectional study with inductive approach with comparative-descriptive procedure and indirect documentation technique. Data were obtained from the DATASUS / SIH-SUS website for the years 2010-2014, considering information for each state of the five Brazilian regions. Admission rates were calculated per 100,000 inhabitants, and data were analyzed by population rates, averages and absolute and relative frequencies. Results: The Northeastern region of Brazil showed the highest hospitalization rate (81.72), followed by the Northern (56.84), Southern (50.94), Midwestern (44.25) and Southeastern regions (30.28). In all regions, the years with the highest hospitalization rates were: 2010 for the Northern (13.17) and Southeastern regions (6.61), 2013 for the Northeastern (20.07) and Midwestern regions (10.17) and 2014 for the Southerner region (10.52). The highest hospitalization rates in all regions of the country in the last five years were observed for male children and adolescent. In relation to age group, higher rates were recorded from 15 to 19 years. Of the total of 27,244 hospitalizations (3.8%), 1028 patients died and 35.5% of them occurred in the Northeastern region. Considering the years under study, the average length of stay and average daily hospitalization cost were respectively 4.0 days and US$ 82.7. Conclusion: The Northeast region of Brazil had the highest hospitalization rate of children and adolescents by craniofacial fractures, and male adolescents and those aged 15-19 years were the most affected in different regions of the country. Costs of hospital admissions due to this type of injury are significant, with more deaths as a result of these injuries in Brazil in the last 5 years evaluated with the highest prevalence in the Northeastern region of Brazil.

Use of the Chronological Dental Mineralization Table of Nicodemo, Moraes and Medici Filho (1974) to Estimate Age by Undergraduate Dentistry Students

Objective: To evaluate the agreement and applicability of the Chronological Dental Mineralization Table of Nicodemo, Moraes and Medici Filho (1974) to estimate age held by undergraduate Dentistry students at the Federal University of Paraíba. Material and Methods: Field research applied with a sample of 50 students according to inclusion and exclusion criteria. Sequentially, 3 panoramic radiographs were exposed (actual age known only by teachers), and students were instructed to interpret them from the selection of 2-4 teeth under formation. Data were analyzed using SPSS software (Statistical Package for Social Sciences), version 20.0, adopting significance level of 5%. Results: Most students chose 3 teeth, with percentages of 56.0% (n = 28); 38.0% (n = 19) and 58.0% (n = 29) for radiographs 1, 2 and 3, respectively. Teeth selected with greater frequency were: 47 (20.1%, n = 33) and 45 (19.5%, n = 32) - radiography 1; 38 (22.7%, n = 32) and 18 (13.4%, n = 19) - radiography 2; and 47 (17.9%; n = 26) and 36 (13.7%; n = 20) - radiography 3. The agreement between estimated and actual ages was 60.0% for radiography 1, 12.0% for radiography 2 and 32.0% for radiography 3. Age was underestimated in 40.0% (n = 20) and 88.0% (n = 44) in radiographs 1 and 2, respectively. Overestimation of the actual age occurred only in radiography 3 (68.0%; n = 34). The linear regression analysis revealed that it is possible to estimate the actual age from the maximum age stipulated by training students with 88.1% success rate. Conclusion: The method is applicable; however, the correlation between estimated and actual ages varied considerably among radiographs, and maximum estimated values were closer to the actual age than minimum values.
