Recovering the function and esthetics of fractured teeth using several restorative cosmetic approaches. Three clinical cases

The teeth most commonly affected by trauma are the maxillary central incisors. The most frequent types of traumatic dental injuries to permanent teeth are enamel fractures, enamel and dentine fractures, and enamel and dentine fractures with pulp involvement. This article describes three clinical cases with different levels of traumatized maxillary incisors and several cosmetic approaches for recovery of the esthetics and the masticatory function, as well as the social/psychological aspects of treatment. All cases involved young adult men. The three clinical cases involve dentin and enamel fractures, dentin and enamel fractures with pulp exposure, and dentin and enamel fractures with pulp exposure associated with root fracture. The cosmetic treatments used to resolve fractures were direct composite resin by layering technique, indirect all-ceramic restorations (laminate veneer and ceramic crowns over the teeth), and immediate implant after extraction followed by immediate loading (ceramic abutments with ceramic crown over implant). In all three cases, excellent functional and esthetic results were achieved by use of these treatment modalities. The patients were very satisfied with the results.

Validade da citologia cervicovaginal na detecção de lesões pré-neoplásicas e neoplásicas de colo de útero

Introdução: O exame colpocitológico ou teste de Papanicolaou permite o diagnóstico precoce do câncer de colo do útero. O êxito no rastreamento desta doença dependerá, além de outros fatores, da acuidade diagnóstica do exame colpocitológico. Objetivos: Avaliar a acurácia diagnóstica da citologia cervicovaginal na detecção de lesões cervicais através da comparação citoistopatológica. Material e métodos: Avaliou-se o grau de concordância entre os exames citológico e histopatológico de 373 pacientes atendidas em um hospital universitário no período de 1990 a 1997 e foram calculados os indicadores: sensibilidade, especificidade, valores preditivos positivos e negativos e as taxas de falsos positivos e falsos negativos do exame. Resultados: A taxa bruta de concordância citoistopatológica foi de 65,1%. A sensibilidade do exame foi alta (96,0%), no entanto sua especificidade foi baixa (51,5%), significando a inclusão de muitos resultados falsos positivos. A taxa de falsos positivos foi de 48,4%, enquanto a de falsos negativos foi de 4%. Discussão: Apesar de a sensibilidade do teste ser alta, sua especificidade é baixa, significando que muitas mulheres seriam falsamente diagnosticadas como doentes, levando a um número elevado de resultados falsos positivos e custos desnecessários, além do potencial caráter iatrogênico que esta ação poderia assumir. No entanto, um exame altamente sensível é o teste de escolha para programas de rastreamento de câncer cervical na população feminina. Conclusões: Para garantir a acuidade diagnóstica do teste de Papanicolaou são essenciais atividades de controle de qualidade nos laboratórios, tanto do procedimento colpocitológico quanto do histopatológico, permitindo, assim, o êxito na detecção precoce e no tratamento das lesões cervicais.

Desordens temporomandibulares e dor orofacial: estudo da qualidade de vida medida pelo Medical Outcomes Study 36 - Item Short Form Health Survey

JUSTIFICATIVA E OBJETIVOS: O conhecimento de indicadores de qualidade de vida (QV) relacionados à saúde bucal é especialmente relevante para a Odontologia considerando o impacto que as condições bucais podem provocar no bem estar psicológico e social. Estudos sobre aspectos psicossociais contribuem para maior integração da conduta clínica e assistencial, preocupação compartilhada com profissionais da saúde. Integrar as áreas de Psicologia e Odontologia quebrando paradigmas interdisciplinares e o interesse em conhecer os aspectos psicológicos dos pacientes, motivou a realização deste estudo. O objetivo deste estudo foi avaliar a QV dos pacientes com disfunção temporomandibular e/ou dor orofacial. MÉTODO: Foi aplicado o Questionário Genérico de Avaliação de Qualidade de Vida - Medical Outcomes Study 36 - Item Short Health Survey (SF-36) a 91 pacientes, que buscaram atendimento por apresentarem sinais e/ou sintomas de disfunção temporomandibular (DTM) e dor orofacial (DOF). O SF-36 avalia 8 domínios: capacidade funcional (CF), aspectos físicos (AF), dor, estado geral de saúde (EGS), saúde mental (SM), aspectos emocionais (AE), aspectos sociais (AS) e vitalidade (V). RESULTADOS: A análise estatística descritiva e inferencial pela Correlação de Pearson (p-valor < 0,05) demonstrou, com exceção da capacidade funcional (73,2), valores médios entre 50 e 64 para os demais domínios: AF - 57,6; Dor - 50; EGS - 54,5; V - 53,4; AS - 63,6; AE - 51,8; SM - 58. Considerando-se que a pontuação varia de 0 a 100, ou seja, do pior para o melhor estado de saúde, os valores médios foram baixos. Verificou-se correlação entre CF e EGS (p-valor 0,01), tendência de significância para dor e EGS (p-valor 0,07). CONCLUSÃO: Os aspectos dor e capacidade funcional interferem no estado geral de saúde; os pacientes com DTM e DOF sofreram impacto negativo na qualidade de vida pelo prejuízo dos aspectos físicos e mentais.

Diagnóstico laboratorial de hemoglobinopatias em populações diferenciadas

The inherited haemoglobinopathies are a heterogeneous group of recessive disorders that include the thalassaemias and sickle cell disease. Nearly a thousand mutant alleles have now been characterized. The mutations are regionally specific and in most cases the geographical and ethnic distribution shave been determined providing the foundation for a program of control through screening, genetic counseling and prenatal diagnosis. The diagnosis of hemoglobinopathies requires care for the methodologies applied and the population group which will be evaluated. The information about the abnormal hemoglobin, the medical and psychological aspects and genetic counseling of the carriers and their families are goals of great importance for the success of preventive programs in this area. Aiming to evaluate the laboratory methods for hemoglobinopathy screening and their use in clinical laboratories, we have compared abnormal hemoglobins incidence in the different population groups: blood donors, anemia carriers, newborn and students. The laboratory methods applied involved eletrophoretic proceedings, cytological and biochemical analysis. Within the period from September 1999 through January 2000, we analyzed 524 individuals with varied types of abnormal hemoglobins. Among blood donors, we diagnosed two sickle cell carriers, which suggest the necessity for better care in the process of selection of blood donor candidates. The current interest in the medical and social aspects of sickle cell anemia has resulted in a great increase in methodology research leading to the development of sickle cell screening techniques.

Survey on tuberculosis teaching in Brazilian nursing schools, 2004

OBJECTIVE: To characterise tuberculosis (TB) teaching in Brazilian nursing schools by state and region and its theoretical and practical contents. METHODOLOGY: In an educational research survey in 2004, 347 nursing schools were identified. Questionnaires were posted to faculties providing training in TB. Data were compiled in a database with a view to descriptive result analysis. Replies to the questionnaire were received by 32% of the nursing schools contacted. RESULTS: Undergraduate TB teaching is heterogeneous. For training in theory, the principle teaching method is through classes in 102 (91.9%) nursing schools. Practical TB teaching is carried out at the primary care level (89.2%). Teachers update their knowledge through events and internet; little reference is made to manuals. The time devoted to practical TB teaching ranges from 10 to 20 hours, although this is not always included in student training. CONCLUSION: Teaching in TB should go beyond the traditional model that focuses only on biological aspects. It should introduce tools that lead to permanent behavioural change, such as a more human approach and social and psychological aspects, such as living conditions, habits and customs. It should involve new partners, such as families, communities and other health professionals, and identify obstacles within the university. © 2006 The Union.

Transtorno bipolar do humor e gênero

Although the bipolar disorder (BD) occurs almost with the same frequency in both genders, the phenomenology and the outcome of the illness differ between them. Nevertheless, there is evidence that women with BD show, more than men, delayed beginning, especially in their fifth decade, more rapid cycling outcome, more depressive episodes, more dysphoric mania, more mixed states and more BD type II. Even so, the findings are not always consistent. Although the risk of comorbidities in BD includes, for both the sorts, excessive alcoholic consumption and drugs, bipolar men would have greater probability of being alcohol dependent, of not seeking treatment and of committing suicide. Suggested hypotheses to explain such differences vary from those centered in cultural or psychological aspects to those that focus on the steroids hormones, and other hormones such as cortisol, thyroid hormones and even on the cerebral anatomy. The reproductive cycle (menstrual cycle, pregnancy and menopause) influences on the BD phenomenology and its relevance to the therapeutical options in the treatment of the BD in women are presented in the last part of this review. Further investigations must to be done in order to clarify this controversy. However, up to now the data indicate that estrogen therapy is not to be primarily indicated to prevent depression, Alzheimer disease or cognition impairment.

Prevalence and associated factors for suicidal ideation and behaviors in obsessive-compulsive disorder

Introduction: Patients with obsessive-compulsive disorder (OCD) have historically been considered at low risk for suicide, but recent studies are controversial. Objective: To study the prevalence of suicidal thoughts and attempts in OCD patients and to compare those with and without suicidality according to demographic and clinical variables. Methods: Fifty outpatients with primary OCD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) from a Brazilian public university were evaluated. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to assess OCD severity, the Beck Depression Inventory to evaluate depressive symptoms and the Alcohol Use Disorders Identification Test to assess alcohol problems. Results: All patients had obsessions and compulsions, 64% a chronic fluctuating course and 62% a minimum Y-BOCS score of 16. Half of the patients presented relevant depressive symptoms, but only three had a history of alcohol problems. Seventy percent reported having already thought that life was not worth living, 56% had wished to be dead, 46% had suicidal ideation, 20% had made suicidal plans, and 10% had already attempted suicide. Current suicidal ideation occurred in 14% of the sample and was significantly associated with a Y-BOCS score ≥16. Previous suicidal thoughts were associated with a Beck Depression Inventory score ≥19. Conclusion: Suicidally has been underestimated in OCD and should be investigated in every patient, so that appropriate preventive measures can be taken.

Obsessive-compulsive disorder: Influence of age at onset on comorbidity patterns

Purpose: This study investigates the influence of age at onset of OCS on psychiatric comorbidities, and tries to establish a cut-off point for age at onset. Methods: Three hundred and thirty OCD patients were consecutively recruited and interviewed using the following structured interviews: Yale-Brown Obsessive Compulsive Scale; Yale Global Tic Severity Scale and the Structured Clinical Interview for DSM-IV. Data were analyzed with regression and cluster analysis. Results: Lower age at onset was associated with a higher probability of having comorbidity with tic, anxiety, somatoform, eating and impulse-control disorders. Longer illness duration was associated with lower chance of having tics. Female gender was associated with anxiety, eating and impulse-control disorders. Tic disorders were associated with anxiety disorders and attention-deficit/hyperactivity disorder. No cut-off age at onset was found to clearly divide the sample in homogeneous subgroups. However, cluster analyses revealed that differences started to emerge at the age of 10 and were more pronounced at the age of 17, suggesting that these were the best cut-off points on this sample. Conclusions: Age at onset is associated with specific comorbidity patterns in OCD patients. More prominent differences are obtained when analyzing age at onset as an absolute value. © 2008 Elsevier Masson SAS. All rights reserved.

Regional odontodysplasia in early childhood: A clinical and histological study

Regional odontodysplasia (RO) is a rare disorder of dental development. The affected teeth are clinically hypoplastic and hypocalcified, presenting a ghost-like appearance radiographically. The aim of this work was to report a clinical case of a child with both primary and permanent dentition affected by RO. The conducted therapy was based on a conservative approach, which consisted of follow-up clinical evaluations of the anomalous teeth. However, the endodontic treatment of the primary incisors failed. Then, the chosen option for patient rehabilitation became extraction followed by removable of prosthesis confection. The extracted teeth were processed for histological analysis. In spite of the uncertain prognosis, but taking into account the psychological aspects of the patient, a conservative approach in an attempt to maintain those viable teeth in the oral cavity should be established.

Perfil antropométrico e fisiológico de atletas de futsal da categoria sub-20 e adulta

The aim of this study was to determine the anthropometrical and physiological profile of futsal players and compare between under-20 and adults categories. Twenty four male athletes futsal participated in the study. They played in two teams of futsal-level state: a team with players under-20 (12 athletes); and another with players of the adults category (12 athletes). The participants performed a routine assessment involving anthropometric measurements (body mass, size, thickness of skin folds, perimeter body and bone diameter) and tests to estimate the aerobic and anaerobic capacity. The results did not indicate differences in relation to the anthropometrical and physiological profile between the under-20 and adults categories. We concluded that the promotion of athletes from the under-20 category for the adult's category taking into account the anthropometrical profile and aerobic and anaerobic performance indicators is recommended. However, other indicators, such as the technical, tactical and psychological aspects are important to help in understanding this promotion phase and in the training. © FTCD/FIP-MOC.
