Knowledge of Dentists about Hypomineralization Enamel Defects: A Cross-Sectional Study

Objective: To evaluate a group of Brazilian dentists on their knowledge of Molar Incisor Hypomineralization (MIH) and Hypomineralized Second Primary Molars (HSPM) related to clinical aspects, consequences, and diagnostic criteria. Material and Methods: In this cross-sectional, the participants were invited by e-mail and Whatsapp® to answer a questionnaire about their knowledge of hypomineralization enamel defects (MIH/HSPM) on the Google Forms® platform. The questionnaire comprised eight questions about personal data and multiple-choice questions about their knowledge concerning clinical aspects, diagnostic criteria of MIH/HSPM and differential diagnosis through clinical images. Chi-square test was applied with the significance level set at 5%. Results: Most participants (n = 492; 91.1%) reported having knowledge about MIH/HSPM. The general dentists gave more incorrect answers (n = 40; 65.6 %;) about dental tissues affected by MIH/HSPM. Overall, 83.3% of the dentists gave the correct answer to which dentitions are associated with this condition. In addition, most dentists presented knowledge about the consequences related to possible fractures (n= 487; 90.2%) and about an increased risk of caries (n= 479; 88.9%) in the affected teeth.  Regarding the differential diagnosis performed through clinical images, most participants gave incorrect answers (p≤0.001). Conclusion: The participants presented knowledge about the dentition associated with this condition and possible consequences related to the teeth affected by MIH/HSPM; however, they showed difficulties concerning clinical diagnostic criteria

No coração das trevas: União Européia, imigração e psiquiatria. O debate civilizacional se repete?

A política de inclusão da União Européia (UE) com relação aos imigrantes “extracomunitários” revela o encontro da diferença ainda marcado pelo “pensamento abissal” na relação com o outro. Contudo, a UE vem se apresentando como um território aberto para o livre-trânsito de cidadãos comunitários. Cabe a interrogação: ao se tratar de um imigrante africano estaria a UE resguardando os estatutos jurídicos do campo dos direitos humanos como o faz aos imigrantes europeus? É sabido que a mão-de-obra imigrante possui papel importante para a economia européia; entretanto, muitas políticas públicas – como as da saúde e as da área da segurança – não refletem essa importância e acabam impondo um silenciamento destes mesmos imigrantes. Nossa intenção está em analisar tal cenário a partir do tratamento psiquiátrico que se apresenta com um olhar transcultural voltado para os imigrantes das ex-colônias portuguesas, buscando desvelar as ressignificações do pensamento colonial diante do imigrante e num contexto de desterritorialização do direito referenciado nos direitos humanos

Ureterolitíase bilateral em um gato de sete meses de idade

Feline ureteral obstruction can have several causes; however, ureterolithiasis has been increasing in occurrence. The restriction of urinary flow induced by the obstruction has harmful consequences to the body and can lead to acute renal failure. Calcium oxalate ureterolithiasis is reported in older cats, aged mean 12 years old. A case of bilateral ureteral obstruction in a 7-month-old mixed breed cat is described in this report. Imaging tests such as abdominal ultrasonography, radiography and excretory urography were performed to determine the diagnosis. The surgical procedure of bilateral ureterotomy was then performed, which allowed the improvement of the urinary flow of both kidneys and the resolution of clinical signs caused by uremia. The quantitative analysis of both uroliths revealed the composition of 100% monohydrate calcium oxalate. Calcium oxalate stones can also cause ureteral obstruction in young cats; although, are less common in this age. When conservative treatment fails, surgical intervention becomes necessary for the rapid return of renal function. To author’s knowledge this is the first report of a ureterolithiasis caused by calcium oxalate in a young cat.A obstrução ureteral em gatos pode ter diversas causas, entretanto, a ureterolitíase vem apresentando um aumento na sua ocorrência. A restrição do fluxo urinário induzida pela obstrução traz consequências graves ao organismo, podendo levar a insuficiência renal aguda. A ureterolitíase por cálculos de oxalato de cálcio é relatada em gatos mais velhos, com média de idade de 12 anos. Um caso de obstrução ureteral bilateral em um gato, SRD, com sete meses de idade é descrito nesse relato. Exames de imagem, como ultrassonografia e radiografia abdominais e urografia excretora, foram realizados para confirmar o diagnóstico. O procedimento cirúrgico de ureterotomia bilateral foi então realizado, permitindo a melhora do fluxo urinário de ambos os rins e dos sinais clínicos de uremia. A análise quantitativa de ambos os urólitos revelou a composição de 100% oxalato de cálcio monohidratado. Cálculos de oxalato de cálcio são um diagnóstico diferencial para obstrução ureteral também em gatos jovens, apesar de serem menos comuns. Quando há falha no tratamento conservador, a intervenção cirúrgica torna-se necessária para o rápido restabelecimento e preservação da função renal. No conhecimento dos autores, esse é o primeiro relato de ureterolitíase causada por oxalato de cálcio em um gato jovem

Prevention and Management of Dental Trauma in Primary Teeth in the Context of the COVID-19: A Critical Literature Review

Objective: To evaluate and discuss the prevention and management of dental trauma in primary teeth during the COVID-19 pandemic. Material and Methods: Critic literature review, searching electronic databases and Google for articles and guidelines published in English that described prevention and management of dental trauma in primary dentition during the pandemic of COVID-19. Results: 5 publications regarding management and 1 leaflet about prevention for parents were identified. Urgent care is required when the child presents tooth fracture resulting in pain or causing soft tissue trauma and luxation affecting bite. Avulsed teeth should not be replanted and advice and self-help may be sufficient in some situations. Instructions about soft diet and hygiene must be provided. Remote consults are recommended for non-urgent situations and during follow-up to evaluate the presence of sequelae. Aerosol generating procedures should be avoided and, in cases of poor prognosis, extraction is recommended to prevent recurring visits to the dental office. Conclusion: During COVID-19 pandemic, remote consults should be recommended to evaluate traumatic dental injuries in primary dentition. Follow-up should not be neglected and may be performed through remote consultation

Adenocarcinoma acinar pulmonar primário em gato : relato de caso

Among the diseases that cause dyspnea in felines, primary pulmonary neoplasia is rare and tends to affect senile cats. This study reports the case of a seven teen year old FeLV infected cat who was diagnosed acinar adenocarcinoma of the lung and kidney metastasis. It presented prostration and anorexia and was hospitalized with dyspnea and pleural effusion. Chest radiography indicated increased radiopacity in the cranial portion of the right hemithorax, compatible with presence of intrathoracic mass and the cytologic analysis of pleural effusion suggested feline infectious peritonitis. The animal died two days after, and the definitive diagnosis was concluded after necropsy and histopathological examination. Pulmonary adenocarcinoma should be included with differential diagnosis of respiratory diseases in cats, especially the elderly.Entre as doenças que causam dispneia em felinos, a neoplasia pulmonar primária é rara e costuma acometer gatos senis. Este trabalho tem por objetivo relatar o caso de um felino, de 17 anos, portador do vírus da leucemia felina, diagnosticado com adenocarcinoma acinar pulmonar primário com metástase no rim e na pleura parietal. O paciente apresentava histórico inespecífico, sendo as principais queixas prostração e anorexia, e foi internado apresentando dispneia e efusão pleural. A radiografia torácica indicou aumento da radiopacidade na porção cranial do hemitórax direito, compatível com presença de neoformação intratorácica. A citologia da efusão foi sugestiva de peritonite infecciosa felina. O animal veio a óbito dois dias após o atendimento inicial e o diagnóstico definitivo foi determinado por meio da necropsia e da avaliação histológica. O adenocarcinoma pulmonar deve ser incluído como diagnóstico diferencial de doenças respiratórias em gatos, principalmente idosos

Intoxicação por amitraz em um gato

A 4-month-old male Himalayan cat presented with clinical signs of acute lethargy and motor incoordination after being treated with amitraz for parasite control. On clinical examination, the patient was lethargic and ataxic with severe pulicosis, hypothermia, pale mucous membranes, bradycardia, weak femoral pulses, hyperglycemia, and bilateral mydriasis. Blood tests revealed non-regenerative hypochromic microcytic anemia. Serum alanine levels were elevated tenfold. The patient received supportive treatment with atipamezole (an α2-adrenergic antagonist) at a dose of 0.1 mg/kg intramuscularly. After 24 h of hospitalization and constant monitoring, the patient recovered and was discharged. The published literature showed that the active ingredient amitraz is effective in the treatment of some parasitic diseases in cats, such as scabies and demodicosis; therefore, it is still used for this purpose. Given the small therapeutic margin of this insecticide, veterinarians should caution owners about its potential toxicity. This report emphasized the significance of amitraz intoxication in feline species and the success of the treatment, which should be initiated in the first hour after intoxication.Um gato da raça Himalaia, macho, com quatro meses de idade, apresentou sinais clínicos de letargia aguda e incoordenação motora após ser medicado com amitraz para controle de parasitas. No exame clínico, o paciente se apresentava letárgico e atáxico, com pulicose grave, hipotermia, mucosaspálidas, bradicardia, pulso femoral fraco, hiperglicemia e midríase bilateral. O exame de sangue revelou anemia microcítica hipocrômica não regenerativa. Os níveis séricos de ALT estavam 10x elevados. O paciente recebeu tratamento de suporte e administração de atipamezol (antagonista α2-adrenérgico) na dose de 0,1 mg/kg por via intramuscular. Após 24 horas de internação e acompanhamento constante, o paciente se recuperou e recebeu alta. Dados publicados na literatura demonstram que o princípio ativo amitraz é eficaz no tratamento de algumas doenças parasitárias em gatos como sarna e demodicose e, portanto, ainda é utilizado para esta finalidade. Dada a pequena margem terapêutica deste inseticida, os veterinários devem informar os proprietários sobre o seu potencial de toxicidade. O objetivo deste relato é enfatizar a importância da intoxicação por amitraz na espécie felina e o sucesso do tratamento, que deve ocorrer nas primeiras horas após a intoxicação

Influence of Environmental Factors on the Presence and Severity of Molar Incisor Hypomineralization

Objective: To assess the association between environmental factors during pregnancy and early childhood with the presence and severity of Molar Incisor Hipomineralization (MIH). Material and Methods: This cross-sectional study was conducted with 120 patients between 7 and 14 years of age. MIH was evaluated according to EAPD criteria. Data collected included the child’s medical history and the mother’s health. Chi-square and logistic regression were performed to determine any statistical evidence of the environmental factors, with the significance level set at 5%. Results: The participants were divided into groups with MIH (n=60) and without MIH (n=60), with average ages of 9.9 (±1.9) and 9.7 (±1.7) years, respectively. There was a statistically significant difference between intercurrences during pregnancy (OR=3.55; IC95%=1.35-10.57) and medication taken by the child (OR=3.01; IC95%=1.74-8.42) and the presence of MIH. In addition, other variables were also associated with the MIH (p≤0.05). However, there was no association with variables and degree of MIH severity (p>0.05). Conclusion: The use of medications in childhood and complications during pregnancy can be association to the presence of MIH. However, these factors do not interaction to MIH severity
