Can habits and behaviors predict colonization by community-associated MRSA in patients admitted to a Brazilian hospital?

This study aimed to identify factors associated with colonization by community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in adult patients admitted to a Brazilian hospital. This is a cross-sectional study, in which patients underwent a nasal swab and were asked about hygiene behavior, habits, and clinical history. Among the 702 patients, 180 (25.6%) had S. aureus and 21 (2.9%) MRSA. The factors associated with MRSA colonization were attending a gym (OR 4.71; 95% CI; 1.42 - 15.06), smoking habit in the last year (OR 2.37; 95% CI; 0.88 - 6.38), previous hospitalization (OR 2.18; CI 95%; 0.89 - 5.25), and shared personal hygiene items (OR 1.99; 95% CI; 0.71 - 5.55). At the time of admission, colonization by CA-MRSA isolates was higher than that found in the general population. This can be an important public health problem, already endemic in hospitals, whose factors such as those associated with habits (smoking cigarettes) and behaviors (team sports practice and activities in gyms) have been strongly highlighted. These findings may help developing infection control policies, allowing targeting patients on higher-risk populations for MRSA colonization.

Methicillin-resistant Staphylococcus aureus and coagulase-negative Staphylococcus produce antimicrobial substances against members of the skin microbiota in children with atopic dermatitis.

Coagulase-negative Staphylococcus (CoNS) species inhibiting Staphylococcus aureus has been described in the skin of atopic dermatitis (AD) patients. This study evaluated whether Staphylococcus spp. from the skin and nares of AD and non-AD children produced antimicrobial substances (AMS). AMS production was screened by an overlay method and tested against NaOH, proteases and 30 indicator strains. Clonality was assessed by pulsed-field gel electrophoresis. Proteinaceous AMS-producers were investigated for autoimmunity by the overlay method and presence of bacteriocin genes by polymerase chain reaction. Two AMS-producers had their genome screened for AMS genes. A methicillin-resistant S. aureus (MRSA) produced proteinaceous AMS that inhibited 51.7% of the staphylococcal indicator strains, and it was active against 60% of the colonies selected from the AD child where it was isolated. On the other hand, 57 (8.8%) CoNS from the nares and skin of AD and non-AD children, most of them S. epidermidis (45.6%), reduced the growth of S. aureus and other CoNS species. Bacteriocin-related genes were detected in the genomes of AMS-producers. AMS production by CoNS inhibited S. aureus and other skin microbiota species from children with AD. Furthermore, an MRSA colonizing a child with AD produced AMS, reinforcing its contribution to dysbiosis and disease severity.

Short Implant and Heavy Smokers as Predictors for Failure of Immediate Implants: a Retrospective Study.

Background: The possibility of installing implants in fresh sockets was first proposed as a viable treatment option in the 1970s. Objective: to assess the relationships of subject-level and implant-level characteristics on the failure of immediate implants installed in sites that contained teeth associated or not with chronic apical periodontitis. Material and Methods: A retrospective study was undertaken with data from patients who received immediate implants with a minimum follow-up of 12 months after loading. The Generalized Estimating Equation, applying a multiple logistic regression model, was employed to investigate the association between predictor variables/co-variables and failure of the immediate implants. Results: Four hundred and twenty-three implants were installed (208 uninfected/215 infected sites) in 186 patients (92 men/96 women) with a mean age of 57.1 years old. The survival rate of implants was 91%. Approximately half (215/50.8%) of the alveoli that received immediate implants had chronic apical periodontitis associated with the extracted teeth, and 191 (88.8%) of these survived until the last follow-up visit. When the infection-free sites were analyzed, this frequency was higher (93,3%), but the presence of chronic apical periodontitis did not show statistical significance in the implant failure (p=0.167). Smokers with a consumption of more than 20 cigarettes/day and short implants had more failures (OR:7.66, p=0.012; OR:14.06, p=0.002; respectively). Conclusions: Short implants and consumption of more than 20 cigarettes/day were important predictors for failure of immediate implants, regardless of presence of chronic apical periodontitis. Key words:Osseointegration, dental implant, smokers, study, immediate dental implant loading.

Interleukin 17 expression in periapical lesions from elderly patients.

OBJECTIVE: To compare the expression of IL-17 in periapical lesions (cysts and granulomas) among elderly individuals and adults. We selected 20 periapical lesions of the elderly (12 granulomas and eight cysts) and 20 periapical lesions of adults (12 granulomas and eight cysts). MATERIALS AND METHODS: Immunohistochemistry was performed using a specific antibody for IL-17. The slides were subdivided into five high magnification fields and then the images were observed through an optical microscope. According to the number of positive markings for the antibody, grades were given, ranging from 0 to 2. RESULTS: The results demonstrate that there was no statistical difference when comparing the expression of IL-17 between cysts and granulomas of both groups (study group: cysts 0.7 ± 0.21 × granulomas 0.96 ± 0.58, p = .61; control group: cysts 0.37 ± 0.16 × granulomas 0.31 ± 0.23, p = .27). The comparison between adult (control group) and elderly patients (study group) showed a statistical difference both in cysts (study group: 0.7 ± 0.21 × control group: 0.37 ± 0.16, p = .007) and in granulomas (study group: 0.96 ± 0.58 × control group: 0.31 ± 0.23, p = .0009), in which elderly patients had a higher expression of interleukin 17, in relation to adult patients. CONCLUSION: We concluded that elderly patients have a higher expression of IL-17 in both cysts and granulomas, when compared to adult patients.

Deciduous Molars Complexity Anatomy Reveled by Computed Microtomography.

OBJECTIVE: The aim of this study was to analyze the internal morphology of deciduous molars through the use of computed microtomography in a sample from Rio de Janeiro. MATERIAL AND METHODS: Thirty maxillary and 30 mandibular deciduous molars (n = 60), divided in first and second primary molars, were scanned by computed microtomography. The teeth were evaluated for root number, root canals, Vertucci classification, root curvature, presence of lateral canals, furcation dentin thickness, structure model index (SMI), volume, and canal surface area. RESULTS: The results showed 100% of maxillary molars had three roots and Vertucci type I canal was more prevalent in this group. In the mandibular ones, type IV was more frequent in the mesial root and class I in the distal root and the cavo-interradicular canal occurred in 2 specimens. Dentin thickness in the furcation region measured 1.53 and 1.59 mm in the maxillary and mandibular, respectively. Volume and area parameters varied according to the evaluated canals and SMI demonstrated that all canals had a cylindrical shape. CONCLUSION: More detailed information about the internal anatomy of the primary molars has been described, which may help strategies in the preparation of these root canals.

Investigation of possible relationship between atopic dermatitis and salivary biomarkers, stress, and sleep disorders.

Atopic dermatitis (AD) is a chronic, relapsing, multifactorial inflammatory disease with genetic, environmental, and immunological characteristics. The quality of life and sleep of patients and their families are affected by AD, which triggers stress, described as one of the factors that worsens AD. Salivary biomarkers such as cortisol, alpha-amylase, chromogranin A, and melatonin have been associated with stress and sleep disturbances. Therefore, the evaluation of stress and sleep disorders using salivary biomarkers in AD patients is important. This review aims to describe the possible relationship between atopic dermatitis and stress, sleep disorders, and salivary biomarkers, seeking to contribute to better understanding and clinical management of AD. This descriptive study is characterized as a narrative literature review. A literature search was conducted of studies published in English and Portuguese between January 2012 and October 2022 that are available in electronic media from various databases, such as Scientific Electronic Library Online, Latin American and Caribbean Literature on Health Sciences, and PubMed. AD is associated with different degrees of impact on the lives of individuals who present with the disease. Psychological stress may induce changes in saliva composition and worsen AD; at the same time, the severity of the disease may be associated with emotional impact. Further studies are needed to assess and correlate AD severity, stress, and sleep disturbances with salivary biomarkers in order to better understand this association.

Is YouTubeTM a reliable source of information regarding ultra-thin ceramic laminates?

An aesthetic smile is usually associated with healthy appearance and success in many areas of life. Currently, individuals access the internet and social media in search of health information. The aim of this study was to analyse the quality and reliability of information in videos available on the YouTubeTM platform about ultra-thin ceramic laminates. Methods: YouTubeTM was searched using the therms "dental ceramic laminates" and "dental contact lens" for videos uploaded on ultra-thin ceramic laminates. The first 100 videos in Portuguese were selected and rated for quality and reliability. The content and source of videos were also noted. The quality of the videos was determined by evaluating the presence or absence of reliable information and distributed into seven domains. To compare the distributions of quantitative variables between the classifications of source, content, and quality, the Kruskal-Wallis and Dunn's post-hoc tests were performed. Results: Seventy-two videos were included for qualitative analysis. Regarding quality rating, most videos were rated with poor quality. The reliability of the evaluated videos was low. Conclusion: YouTubeTM showed a large number of videos with many views on the topic, but it does not contribute with good quality and reliable information to the population

Methicillin-resistant and methicillin-sensitive Staphylococcus aureus isolates from skin and nares of Brazilian children with atopic dermatitis demonstrate high level of clonal diversity.

BACKGROUND: Atopic dermatitis (AD) primarily affects the pediatric population, which is highly colonized by S. aureus. However, little is known about the genetic features of this microorganism and other staphylococcal species that colonize AD patients. OBJECTIVE: This study aimed to characterize Staphylococcus spp. isolated from the nares and skin (with and without lesion) of 30 AD and 12 non-AD Brazilian children. METHODS: Skin and nasal swabs were cultured onto mannitol salt agar, and bacterial colonies were counted and identified by matrix assisted laser desorption ionization time of flight mass spectrometry and polymerase chain reaction (PCR). Antimicrobial susceptibility was evaluated by phenotypic and genotypic tests. In S. aureus isolates, Panton-Valentine leukocidin genes were detected by PCR, and their clonality was assessed by pulsed-field gel electrophoresis and multilocus sequence typing. RESULTS: S. aureus was more prevalent in the nares (P = 0.005) and lesional skin (P = 0.0002) of children with AD, while S. hominis was more frequent in the skin of non-AD children (P < 0.0001). All children in the study, except one from each group, were colonized by methicillin-resistant coagulase-negative Staphylococcus and 24% by methicillin-resistant S. aureus. Despite the great clonal diversity of S. aureus (18 sequence types identified), most AD children (74.1%) were colonized by the same genotype in both niches. CONCLUSION: High colonization by polyclonal S. aureus isolates was found among children with AD, while S. hominis was more frequent among non-AD children. The high prevalence of methicillin-resistant staphylococcal isolates highlights the importance of continued surveillance, especially when considering empiric antibiotic therapy for the treatment of skin infections in these patients.

Risk factors for survival after head and neck cancer: a cohort study in the south of Espirito Santo state

Introduction: Head and check squamous cell carcinomas (HNSCC) affects the Brazilian population with a high incidence and usually has a poor prognosis. Objective: To evaluate the risk factors for survival of patients diagnosed with HNSCC and investigate the influence of epidemiological and clinical factors on the prognostic of HNSCC in southeastern Brazil. Materials and Methods: Clinical records of 211 patients with head and neck squamous cell carcinomas diagnosed and treated between 2010 and 2018 at a reference hospital for oncology, were selected. Clinical and pathological characteristics at diagnosis and for 5 years follow up were collected. The Kaplan-Meier Curve with the Log-Rank test assessed survival, and forward stepwise multivariate logistic regression model was performed to determine the factors affecting HNSCC survival. Results: The 5-year overall survival was 30.0%. Laryngeal cancer was the most prevalent (34.1%), followed by oropharynx (33.6%) and oral cavity (24.2%). About 64% of patients had locally advanced tumors (T3 and T4) and 75.4% of the patients were diagnosed as being in the advanced clinical stages (III and IV). In the multivariate analysis, the locally advanced tumors (OR=2.748; 95%CI:1.310- 5.765), palliative chemotherapy (OR=15.757; 95%CI:5.868-42.309) and metastasis during oncological follow-up (OR=11.602; 95%CI:1.380-97.507) were associated with a poor prognosis. Conclusion: The survival rate was considered low when compared with the literature. Locally advanced tumors, palliative chemotherapy, and the appearance of metastases during follow-up were considered the most important risk factors associated with a low HNSCC survival.

Introdução: O carcinoma de células escamosas (CCE) de cabeça e pescoço possui alta incidência na população brasileira e normalmente está associado a um prognóstico desfavorável. Objetivo: Avaliar os fatores de risco para sobrevida de pacientes diagnosticados com CCE de cabeça e pescoço e investigar a influência de fatores clínicoepidemiológicos no prognóstico do CCE. Materiais e Métodos: Foram selecionados prontuários de 211 pacientes com CCE de cabeça e pescoço diagnosticados e tratados entre 2010 e 2018 em um hospital de referência em oncologia. Foram coletadas as características clínico-patológicas no momento do diagnóstico e nos 5 anos de acompanhamento. A curva de Kaplan-Meier com o teste Log-Rank avaliou a sobrevivência e o modelo de regressão logística multivariada progressiva foram realizados para determinar os fatores que afetaram a sobrevivência do CCE. Resultados: A sobrevida global em 5 anos foi de 30,0%. O câncer de laringe foi o mais prevalente (34,1%), seguido de orofaringe (33,6%) e cavidade oral (24,2%). 64% dos pacientes apresentavam tumores localmente avançados (T3 e T4) e 75,4% dos pacientes foram diagnosticados em estádios clínicos avançados (III e IV). Na análise multivariada, os tumores localmente avançados (RC = 2,748; IC 95%: 1,310-5,765), quimioterapia paliativa (RC = 15,757; IC 95%: 5,868-42,309) e metástases durante o acompanhamento oncológico (RC = 11,602; IC 95%: 1,380-97,507) foram associados a um pior prognóstico. Conclusão: A taxa de sobrevida foi considerada baixa. Tumores localmente avançados, quimioterapia paliativa e aparecimento de metástases durante o seguimento foram considerados os fatores de risco mais importantes associados a uma baixa sobrevida.

Aging as a Risk Factor on the Immunoexpression of Pro-Inflammatory IL-1ß, IL-6 and TNF-α Cytokines in Chronic Apical Periodontitis Lesions.

Persistent inflammatory responses in the elderly may act as modifiers on the progression and repair of chronic apical periodontitis lesions (CAPLs). While the involvement of IL-1ß, IL-6 and TNF-α in inflammatory responses and, particularly, in CAPL has been documented, their expression in elderly patients needs to be further characterized. Therefore, the purpose of this study was to evaluate and compare the expressions of pro-inflammatory cytokines in CAPL from elderly individuals with young/middle-aged individuals. Thirty CAPL (15 cysts and 15 granulomas) from elderly patients (>60 years) and 30 CAPL (15 cysts and 15 granuloma) from young/middle-aged individuals (20-56 years) were selected. Immunohistochemical reactions were performed against IL-1ß, IL-6 and TNF-α. The slides were subdivided into five high-magnification fields and analyzed. The number of positive stains was evaluated for each antibody. There was no significant difference between the cytokines when the cysts and granuloma were compared in the two groups. In the young/middle-aged, only IL-1ß showed a difference and was significantly higher in granulomas (p = 0.019). CAPL pro-inflammatory cytokine levels in the elderly were significantly higher than in young/middle-aged individuals (p < 0.05). The pro-inflammatory cytokines IL-1ß, IL-6 and TNF-α were significantly higher in CAPL in the elderly compared with the young/middle-aged group. Further elaborate research studies/analyses to elucidate the reasons for and consequences of inflammation in the elderly are recommended.

Clinical oral profile of pediatric patients with atopic dermatitis: A cross-sectional study.

OBJECTIVES: This work aims to describe oral health conditions, eating habits, and oral hygiene in pediatric and adolescent patients with atopic dermatitis and correlate them with the severity of the Scoring Atopic Dermatitis (SCORAD). Also, we aim to estimate the effect of several variables on the diagnosis of dental caries in these patients. MATERIAL AND METHODS: A total of 92 children and adolescents with atopic dermatitis had their oral cavities examined. The effect of independent variables on the diagnosis of dental caries (outcome) was assessed using multiple binary logistic regression model. RESULTS: Mild patients presented higher score of decayed, missing, and filled teeth in permanent dentition than moderate patients (p = 0.040). In the multivariable regression final model, the covariates using inhaled corticoid (OR = 6.4; p = 0.003), type of teething [deciduous dentition (OR = 7.9; p = 0.027) and mixed dentition (OR = 10.5; p = 0.007)], and brushing quality [poor mechanical control (OR = 10.6; p < 0.0001)] demonstrated significant direct effect on the diagnosis of dental caries. CONCLUSIONS: Our findings suggest that the presence of dental biofilm, use of inhaled corticoid, and type of teething are related to the presence of caries in atopic dermatitis patients.

Syphilis among HIV serodiscordant partners associated with Human Papillomavirus Infection in a bisexual man / Sífilis entre parceiros sorodiscordantes para HIV associada à infecção por papilomavírus humano em um homem bissexual

Introduction: Syphilis and HIV infections are sexually transmitted infections whose diagnosis and treatment contribute toward preventing congenital transmission. Objective: To report a case of three sexually transmitted infections detected in a male partner during Couple Consultation and syphilis in the female partner during prenatal care. Case report: A 34-year-old black female G2P1 pregnant woman was referred to an outpatient clinic of sexually transmitted infections in Vitória, Brazil, reporting a 30-day evolution of painless papular lesions in the external genitalia, suggestive of condylomata lata. Nontreponemal tests were positive for syphilis and negative for HIV. The husband reported unprotected receptive anal intercourse and possessed anal condylomatous lesions and perianal condylomata lata. He was positive for both HIV and syphilis. Histopathological findings showed low-grade HPV lesions and the PCR test found 16, 39, and 53 HPV subtypes. Treatment with benzathine penicillin G was successful for both partners. Conclusion: This study emphasizes the need for Couple Consultation during pregnancy to identify and treat possible sexually transmitted infections.

Introdução: As infecções por sífilis e HIV são infecções sexualmente transmissíveis cujo diagnóstico e tratamento contribuem para a prevenção da transmissão congênita.

Conclusão: Este estudo enfatiza a necessidade de consultas de casal durante a gravidez para identificar e tratar possíveis infecções sexualmente transmissíveis.

Covid-19 e Odontologia: análise de informações disponíveis em uma plataforma virtual. Um estudo descritivo e observacional / Covid-19 and Dentistry: analysis of available information on a virtual platform. A descriptive and observational study

Objetivo: avaliar as informações disponíveis no site de buscas Google® sobre a relação entre a odontologia e a infecção pelo novo Coronavírus, e sua concordância com a literatura atual. Material e Métodos: estudo descritivo e observacional, realizado em uma universidade privada em Rio de Janeiro, Brasil, através da utilização da plataforma de buscas Google® aonde analisou-se os sites através de um roteiro de perguntas previamente elaborado. Resultados: foram analisados 67 sites após buscas pelas expressões "Coronavírus e odontologia", "Saúde bucal e Coronavírus" e "Fratura de dente e Coronavírus". Apenas 24,2% das perguntas foram respondidas com conteúdo completo enquanto 62,5% não apresentavam os conteúdos e 13,3% simplesmente os citavam sem dar maiores esclarecimentos. Apesar disso, 99% dos conteúdos foram publicados por fontes confiáveis (órgãos renomados, sites privados de profissionais da saúde bucal ou matérias de jornal assessoradas por estes). Conclusão: Apesar de confiáveis, os resultados das buscas apresentaram pequena quantidade de informações que realmente auxiliariam o leigo no entendimento da relação entre Coronavírus e odontologia, o que demonstra a necessidade de criação de canais oficiais para disseminação destas para o público geral

Objective:to evaluate the information available on the Google® search site concerning the relationship between dentistry and infection with the new coronavirus, and its concurrence with the current literature. Material and Methods: a descriptive and observational study was conducted by a private university in Rio de Janeiro, Brazil, to analyze the Google® search platform and the sites found through a previously prepared questionnaire. Results: the expressions "Coronavirus and dentistry", "Oral health and Coronavirus" and "Tooth fracture and Coronavirus" searched produced 67 sites for analysis. However, only 24.2% of the questions of the questionnaire were answered fully, while 62.5% did not answer them at all and 13.3% simply cited them without giving details. Notwithstanding this, 99% of the contents were published by official entities, dental websites or articles assisted by oral health care professionals. Conclusion: although reliable, the search results presented little information that would really help a layperson understand the relationship between Coronavirus and dentistry, which demonstrates the need to create official channels to disseminate such information to the public in an appropriate manner

High incidence of acquiring methicillin-resistant Staphylococcus aureus in Brazilian children with Atopic Dermatitis and associated risk factors.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) colonization in Atopic Dermatitis (AD) patients can contribute to worsening their clinical condition. OBJECTIVE: A cohort study was carried out to determine the incidence of MRSA acquisition and its risk factors in AD children. METHODS: Patients with AD (2 months-14 years old) were followed up for about 1 year at a reference center for AD treatment in Rio de Janeiro, Brazil, from September 2011 to February 2014. Nasal swabs from patients and contacts were collected every 2 months. The SCORAD system assessed the severity of the AD. S. aureus isolates were evaluated to determine the methicillin resistance and the clonal lineages. RESULTS: Among 117 AD patients, 97 (82.9%) were already colonized with S. aureus and 26 (22.2%) had MRSA at the first evaluation. The incidence of MRSA acquisition in the cohort study was 27.47% (n = 25). The SCORAD assessments were: mild (46.15%), moderate (37.36%) or severe (16.48%). Risk factors were: colonized MRSA contacts (HR = 2.27; 95% CI: 1.16-7.54), use of cyclosporine (HR = 5.84; 95% CI: 1.70-19.98), moderate or severe AD (HR = 3.26; 95% CI: 1.13-9.37). Protective factors were: availability of running water (HR = 0.21; 95% CI: 0.049-0.96) and use of antihistamines (HR = 0.21; 95% IC: 0.64-0.75). MRSA isolates carried the SCCmec type IV and most of them were typed as USA800/ST5. CONCLUSIONS: The high incidence of MRSA acquisition found among AD patients and the risk factors associated show that an effective surveillance of MRSA colonization in these patients is needed.

Alterações bucais associadas à presença de atopia em crianças: um estudo transversal / Oral changes associated with the presence of atopy in children: a cross-sectional study

Resumo Introdução É por meio da interação entre ambiente, indivíduo, sua predisposição à atopia e exposição a alérgenos que surgem as doenças alérgicas. Em crianças atópicas, foi observada uma alta prevalência de padrão respirador bucal, assim como resposta positiva a testes alérgicos. Essas alterações respiratórias possuem uma associação com deformidades orofaciais, especialmente as maloclusões. Objetivo Identificar a frequência de crianças e adolescentes portadores de alergias e buscar uma provável associação entre atopia e maloclusão, traumatismos dentoalveolares e hábitos bucais viciosos. Material e método Foram avaliados prontuários de crianças e adolescentes atendidos em duas instituições particulares de ensino da cidade do Rio de Janeiro no período compreendido entre agosto de 2017 e julho de 2018. Foram coletados dados do prontuário relacionados ao histórico médico, odontológico e de alergias. Os dados foram analisados descritivamente e por meio do teste qui-quadrado (p<0,05). Resultado Um total de 136 prontuários foi considerado elegível para avaliação. Durante a anamnese, 49 responsáveis (36%) relataram histórico de alergias em suas crianças e adolescentes. A prevalência de hábitos bucais viciosos foi verificada em 87 pacientes (64%), sendo presente em 65,3% de crianças e adolescentes que apresentavam atopia (p<0,05). Conclusão A prevalência de alergias relatada nesta população foi de 34,6%, e foi observada ainda uma alta prevalência de hábitos bucais viciosos e traumatismos dentoalveolares nesses pacientes. Foram constatadas associações significativas entre presença de atopias e histórico de traumatismos dentários, maloclusão e hábitos viciosos, demonstrando haver correlação entre atopia e alguns aspectos de saúde oral.

Abstract Introduction Allergic diseases appear through the interaction between the environment, the individual, their predisposition to atopy and exposure to allergens. In atopic children there is a high prevalence of mouth breathers, as well as positive response to allergic prick tests. These respiratory changes have an association with orofacial deformities especially malocclusions. Objective To identify the frequency of children and adolescents that have atopies and search for a probable association between atopy and oral aspects like malocclusion and vicious oral habits. Material and method Medical records were taken of children and adolescents seen at two educational institutions in the city of Rio de Janeiro in the period between August 2017 and July 2018. Data were collected from medical records related to medical history, history of atopies and dental history. The data were transmitted descriptively through the chi-square test (p<0.05). Result A total of 136 records were considered eligible for evaluation. During the anamnesis, 49 (36.0%) parents reported a history of atopy in their children adolescents. The prevalence of vicious oral habits was found in 87 children and adolescents (64.0%), being presented in 65.3% of the patients who had atopy (p<0.05). Conclusion It can be observed that the prevalence of atopy reported in this population was 34.6% and there was also a high prevalence of vicious oral habits and dento-alveolar trauma in these patients. Relevant associations between the presence of atopies and history of dental trauma, malocclusion and the presence of oral vicious habits were observed, demonstrating a correlation between atopy and some aspects of oral health.

Trauma in Primary Teeth at a Specialized Service Center: Retrospective Cohort

Abstract Objective: To evaluate the factors associated with the occurrence of dental trauma in children up to six years of age and describe the results of clinical follow-up and possible sequelae. Material and Methods: A retrospective study was carried out with data collected from the dental records of 96 pediatric patients up to 6 years old with traumatized primary teeth who sought care from the. Pediatric Dental Trauma project of a private university in the city of Rio de Janeiro from July 2014 to July 2017, and who had clinical and radiographic follow-up for up to three months as of their initial visit. Results: 96 children (58.3% boys and 41.7% girls) included who presented 166 traumatized primary teeth. Intrusion was the most observed type of trauma and in 45.8% of cases, the care occurred one-week post trauma. The maxillary central incisors were the most affected teeth (97.6%). The prognosis of the dental elements with more than 3 months of follow-up was considered favorable, and 59.6% of the teeth did not present any clinical or radiological sequelae. Oral hygiene instruction and monitoring were the most common approaches. Conclusion: The prevalence of dental trauma in the present study was high and occurred mainly in domestic settings. The upper central incisors were the teeth that suffered the most injuries. The presence of patients at follow-up visits was an important factor for the positive result in most cases.

CONHECIMENTO SOBRE BEIJO NA BOCA DE ADOLESCENTES DE UM GRUPO DE ESCOLAS PRIVADAS DE NOVA IGUAÇU/RIO DE JANEIRO ­ ESTUDO PILOTO / KNOWLEDGE ABOUT KISSING IN THE MOUTH OF ADOLESCENTS FROM A GROUP OF PRIVATE SCHOOLS IN NOVA IGUAÇU / RIO DE JANEIRO - PILOT STUDY

Objetivo: Descrever os conhecimentos sobre o beijo na boca e sua possibilidade de transmissão de doenças infecciosas em um grupo de adolescentes de escolas privadas de Nova Iguaçu/Rio de Janeiro, através deste estudo piloto. Metodologia: Estudo seccional em que foi aplicado um roteiro de perguntas semi-estruturado autoaplicável em adolescentes (de 18 e 19 anos) de ambos os gêneros, pertencentes a três escolas da rede de ensino privado do município de Nova Iguaçu no Estado do Rio de Janeiro. Resultados: De um total de 100 adolescentes que participaram deste estudo, mais da metade eram solteiros e do gênero feminino (61%), apenas estudantes como ocupação (88% do total) e 96% já haviam beijado na boca. A amostra selecionada demonstrou características próprias, com a alta frequência do conhecimento da possibilidade de transmissão de doenças infecciosas pelo beijo na boca e saliva (71%), que possivelmente se confirmou pela baixa ocorrência de lesões após o ato do beijo e pela observação da boca do parceiro antes de beijar. Conclusão: A pratica do beijo na boca e o sexo oral devem ser temáticas consideradas na assistência fornecida a adolescentes. O uso de estratégias preventivas e o acesso às redes sociais podem contribuir para a redução de situações de risco advindos de situações de vulnerabilidade.

Aim: To describe the knowledge about the kiss on the mouth and its possibility of transmission of infectious diseases in a group of adolescents from private schools in Nova Iguaçu / Rio de Janeiro, through this pilot study. Methodology: Cross-sectional study in which a self-administered semi-structured question script was applied to adolescents (18 and 19 years) of both genders, belonging to three schools of the private school system of Nova Iguaçu, Rio de Janeiro State. Results: Of a total of 100 adolescents who participated in this study, more than half were single and female (61%), only students as occupation (88% of the total) and 96% had already kissed the mouth. The selected sample demonstrated its own characteristics, with the high frequency of the knowledge of the possibility of transmission of infectious diseases by kissing in the mouth and saliva (71%), which was possibly confirmed by the low occurrence of lesions after the kiss and the observation of the mouth. of the partner before kissing. Conclusion: The practice of kissing on the mouth and oral sex should be thematic considered in the care provided to adolescents. The use of preventive strategies and access to social networks can contribute to the reduction of risk situations arising from vulnerability situations.

Osteoradionecrosis in a Patient Submitted to Head and Neck Radiotherapy: A Case Report / Osteoradionecrosis en un Paciente Sometido a Radioterapia de Cabeza y Cuello: Reporte de un Caso

ABSTRACT: Radiotherapy applies ionizing radiation at predetermined doses for a limited period of time in order to destroy tumors. The oral cavity, which has a high rate of cell renewal, is affected by the side effects of radiotherapy including osteoradionecrosis (ORN). This condition occurs due to irradiated bone tissue that becomes devitalized and exposed in the oral cavity. Conservative therapies are recommended for ORN lesions that are not extensive or in an early stage. Surgical intervention is necessary for extensive areas affected by necrosis. This study reports a case of ORN in the left mandibular body which resulted in a pathological fracture. The treatment consisted of segmental mandibulectomy and the use of a reconstruction plate. Also, low-level laser therapy around bone exposure was performed. After surgery, the patient underwent 6 months of follow-up and was satisfied with the outcome. However, the patient died before control of ORN was achieved due to a heart attack.

RESUMEN: La radioterapia aplica radiación ionizante a dosis predeterminadas durante un período de tiempo limitado para destruir tumores. La cavidad oral, que tiene una alta tasa de renovación celular, se ve afectada por los efectos secundarios de la radioterapia, incluida la osteorradionecrosis (ORN). Esta condición se produce debido al tejido óseo irradiado que se desvitaliza y expone en la cavidad oral. Se recomiendan terapias conservadoras para las lesiones de ORN que no son extensas o en una etapa temprana. La intervención quirúrgica es necesaria para áreas extensas afectadas por necrosis. Este estudio reporta un caso de ORN en el cuerpo mandibular izquierdo que resultó en una fractura patológica. El tratamiento consistió en mandibulectomía segmentaria y el uso de una placa de reconstrucción. Además, se realizó una terapia con láser de bajo nivel alrededor de la exposición ósea. Después de la cirugía, el paciente se sometió a 6 meses de seguimiento y quedó satisfecho con el resultado. Sin embargo, el paciente falleció antes de que se lograra el control de ORN debido a un ataque cardíaco.
