Epidemiology of Severity of Temporomandibular Disorders in Brazilian Women

Aims: To evaluate the severity of temporomandibular disorders (TMD) of women in the municipality of Araraquara (Brazil) as well as the contribution of the perception of oral health, mandibular functional limitation, and sociodemographic variables on the severity of TMD. Methods: The participants were interviewed by telephone. Information regarding age, marital status, economic level, education, and use and type of dental prostheses was surveyed. To evaluate TMD severity, mandibular functional limitation and perception of oral health, Fonseca's Anamnesic Index (IAF), the Mandibular Function Impairment Questionnaire (MFIQ), and the General Oral Health Assessment Index (GOHAI) were used. To evaluate the contribution of these variables on TMD severity, a structural equation model (SEM) was fitted to the data and assessed by usual goodness-of-fit indices. Results: A total of 701 women with a mean age of 44.36 years (SD = 16.31) participated. According to the IAF, 59.6% (95% confidence interval = 56.00%-63.2%) of the women were classified as having TMD, of which 63.9% presented light, 26.8% moderate, and 9.3% severe TMD. Mandibular functional limitation was low in 91.0% of the women, moderate in 7.1%, and severe in 1.9%. Goodness-of-fit for the structural model was adequate. The predictors explained 43% of the variation in the TMD severity, with significant contributions of the variables dental prostheses (beta = -.008; P = .006), perception of oral health (beta = -.43; P < .001), and mandibular functional limitation (beta = .014; P = 014). Conclusion: The severity of TMD among Brazilian women was greater in non-users of dental prostheses and was also associated with greater mandibular functional limitation and poor perception of oral health.

Hyperlipidemia as a risk factor of renal allograft function impairment

In this study, the graft outcome in renal allograft recipients with [high cholesterol group (HCG), n = 30] or without [normal cholesterol group (NCG), n = 42] hypercholesterolemia and with [high triglyceride group (HTG), n = 33] or without [normal triglyceride group (NTG), n = 36] hypertriglyceridemia were prospectively compared. At 6 months post-transplantation, no significant difference was observed between the groups (NTG compared with HTG, and NCG compared with HCG) regarding age, presence of arterial hypertension, kind of donor (living related or cadaveric), immunosuppressive therapy, number of rejection episodes per patient, frequency of patients with acute cellular rejection, prevalence of patients with diabetes mellitus or proteinuria > 3 g/24 h, and mean serum creatinine. The probability of doubling serum creatinine during follow-up was statistically different between NTG and HTG (12 months: NTG = 0.03, HTG = 0.15; 36 months: NTG = 0.08, HTG = 0.33; 60 months: NTG = 0.08, HTG = 0.48; and 120 months: NTG = 0.18, HTG = 0.48), but not between NCG and HCG (12 months: NCG = 0.05, HCG = 0.13; 36 months: NCG = 0.13, HCG = 0.24; 60 months: NCG = 0.19, HCG = 0.31; 84 months: NCG = 0.27, HCG = 0.31). There was no significant difference in actuarial graft survival between HCG and NCG or between NTG and HTG. Hypertriglyceridemia, but not hypercholesterolemia, was associated with loss of graft function.

Consistência interna e reprodutibilidade da versão em português do critério de diagnóstico na pesquisa para desordens temporomandibulares (RDC/TMD - Eixo II)

OBJETIVO: Estudar a confiabilidade, da versão em português, do questionário para o diagnóstico psicológico e psicossocial dos indivíduos com desordens temporomandibulares (RDC/TMD). MÉTODOS: Foram entrevistados 109 indivíduos, de ambos sexos, que demandaram atendimento junto à Clínica de Fisioterapia do Centro Universitário de Araraquara, de janeiro a julho de 2006. Os questionários foram aplicados por um único examinador. Após duas semanas, o mesmo foi reaplicado em 36 indivíduos. Para avaliação da consistência interna do método, utilizou-se o Coeficiente Alfa de Cronbach; para análise da reprodutibilidade intra-examinador, o Coeficiente de Correlação Intraclasse (ro) e a estatística Kappa (kapa), respectivamente às variáveis de natureza quantitativa e qualitativa. RESULTADOS: A consistência interna para as dimensões intensidade da dor crônica e incapacidade; limitação da função mandibular; sintomas físicos não-específicos, incluindo os itens de dor; sintomas físicos não-específicos, excluindo os itens de dor e depressão foi de 0,8479, 0,8971, 0,8673, 0,8080 e 0,9270 respectivamente, atestando ao método excelente validade interna. Obteve-se excelente concordância intra-examinador para as questões referentes ao tempo de presença da dor e sua gradação, e boa para a questão referente à dor presente. Os menores valores de kapa relacionaram-se aos itens de sintomas físicos e depressão. A percepção de estalos ou rangidos pelos indivíduos apresentou concordância regular bem como a questão referente à procura de profissional para tratamento da dor. As demais questões apresentaram reprodutibilidade boa e ótima, sendo que a maioria dessas apresentou nível máximo de concordância. CONCLUSÃO: A versão adaptada para o português mostrou-se confiável para detecção das alterações psicológicas e psicossociais associadas às desordens temporomandibulares.

Participação da excreção renal de cálcio, fósforo, sódio e potássio na homeostase em cães sadios e cães com doença renal crônica

Na doença renal crônica (DRC) a manutenção da homeostase de água e sódio é o primeiro problema a ser contornado pelo organismo e com o agravamento das lesões renais surgem outros problemas graves relacionados à homeostase de cálcio e fósforo. O presente estudo tem por escopo avaliar a excreção renal de cálcio, fósforo, sódio e potássio, e o perfil sérico destes eletrólitos em cães normais e em cães com DRC naturalmente adquirida. Foram avaliados três grupos de cães adultos, machos ou fêmeas, de raças variadas. Animais normais compuseram o grupo controle (G1) e os cães com DRC foram distribuídos em dois grupos de acordo com os estágios de comprometimento da função renal (G2 e G3, respectivamente, estágios 1-2 e estágios 3-4, descritos pela IRIS 2006 staging CKD). Os cães do G3 apresentaram aumento das concentrações séricas de cálcio ionizado e fósforo, além de diminuição da concentração sérica de sódio. Quanto à excreção renal dos eletrólitos analisados, os animais dos grupos G1 e G2 apresentaram diminuição de carga filtrada e aumento de excreção fracionada, mas as excreções urinárias não variaram significativamente. Os resultados são indicativos de que os rins de cães com DRC podem manter a excreção urinária dos eletrólitos em valores se melhantes aos dos normais. O mecanismo envolve aumento da excreção fracionada na medida em que haja diminuição da filtração glomerular. Esse processo de compensação, entretanto, pode perder a eficiência nos estágios mais avançados da enfermidade no que se refere à manutenção das concentrações séricas de fósforo e sódio.

Impairment of adult male reproductive function in rats exposed to ethanol since puberty

The objective of this work was to evaluate reproductive function in adult male rats exposed to ethanol since puberty. Male Wistar rats, 50 days old, received a liquid diet with 36% of the daily calories derived from ethanol or an isocaloric control diet for 55 days. The ethanol treatment impaired sexual behavior and only 22% of these rats reached ejaculation. The fertility of ethanol-treated animals was significantly reduced, mainly after natural mating. Serum testosterone levels, daily sperm production and sperm count in the epididymis were also significantly diminished after ethanol treatment, associated with an acceleration of the sperm transit time in the cauda epididymidis, decrease in sperm motility and increased percentage of abnormal shaped sperm cells. The results showed that chronic consumption of ethanol beginning at puberty impairs the reproductive function of adult male rats. (c) 2006 Elsevier B.V. All rights reserved.

Effects of mandibular fixed implant-supported prostheses on masticatory and swallowing functions in completely edentulous elderly individuals

Purpose: To evaluate the effect of oral rehabilitation with immediately loaded fixed implant-supported mandibular prostheses on chewing and swallowing in elderly individuals. Materials and Methods: Fifteen completely edentulous patients aged more than 60 years (10 women and rive men), wearing removable dentures in both arches, had a mandibular denture replaced by an implant-supported prosthesis. All individuals were evaluated before surgery and again 3, 6, and 18 months later with regard to mastication and swallowing conditions. Examinations entailed an interview, evaluation of tactile sensitivity of the face, and observation of food intake, masticatory type, formations of bolus, and pain during mastication. The swallowing evaluation comprised observation of clinical signs related to the oral and pharyngeal stages of swallowing, as well as the presence of oral residue. The findings of different evaluations before and 3, 6, and 18 months after the surgical-prosthetic procedure were statistically compared by analysis of variance for repeated measurements at a significance level of 5%. Results: The questionnaire revealed a reduction in complaints of masticatory and swallowing disturbances, a decreased need for liquid ingestion, and reduced choking and coughing. Clinical evaluations showed improved oral function and bolus propulsion for both solid and paste-consistency foods; pain during mastication was also resolved. Conclusion: Treatment with mandibular implant-supported dentures had positive effects on the clinical aspects of mastication and swallowing in elderly individuals.

Greater level of physical activity associated with better cognitive function in hemodialysis in end stage renal disease

Patients with chronic kidney disease (CKD) have a lower exercise tolerance and poor functional capacity, carry on a sedentary lifestyle. Another important change found in patients with CKD is cognitive dysfunction. Physical inactivity has been associated with cognitive dysfunction in the general population, but few studies have evaluated this association in CKD. To assess the association between physical activity and cognitive function in patients with CKD on hemodialysis (HD). We evaluated 102 patients undergoing HD. The participants completed the International Physical Activity Questionnaire, which assesses the level of physical activity and the Mini Mental State Examination, used for cognitive screening. Patients were divided into three groups according to their level of physical activity (GI: active/GII: irregularly active/GIII: sedentary). It was applied logistic regression analysis and adopted as outcome variable the presence of cognitive impairment and preserving as independent variables those with a probability of statistical difference between groups of less than 0.1. It was considered statistically significant when p less than 0.05. The groups were similar in age, duration of HD, and smoking. Statistically significant difference regarding race, body mass index, diabetes mellitus, underlying disease and degree of cognitive impairment. Regarding laboratory data, the groups differed in terms of creatinine, glucose, hemoglobin and hematocrit. There was significant association with better physical activity and cognitive function, even adjusting for confounding variables. the highest level of physical activity was associated with better cognitive function in CKD patients undergoing HD.

Parafunção severa: reabilitação oral com prótese total mandibular x overlay maxilar: relato de caso

In many oral rehabilitation professionals seeking venture renew people smile. However, these procedures have functional implications and aesthetic criteria which must be satisfied so that the final result is predictable. The restoration of relations intermaxillary, phonetics, masticatory function, esthetics and patient comfort are the goals to be achieved. An effective way to achieve these goals when immediate reconstruction with permanent dentures is not possible, make use of a type of partial denture called overlay. Bruxism is a manifestation of biopsychological imbalance that affects the stomatognathic system, characterized by clenching and / or attrition of teeth together so centric or eccentric, can be manifestation of nocturnal or diurnal. Its effects can manifest themselves in different parts of the stomatognathic system, varying the severity of the damage as the resistance of the structures affected, the time of existence, its regularity and the general state of the wearer. The description of the steps followed in solving this case, in which the patient edentulous mandibular arch while the maxillary arch showed absence of teeth 16 and 26 and, except for the teeth 17 and 27, all other teeth showed wear very sharp in the sense denoting incisal cervical, severe impairment of the vertical dimension, the quality of masticatory function and a marked impairment phonetic, this case report aims to guide the beginning of a rehabilitation, as well as the transitional phase of treatment for recovery of functional and aesthetic relationships intermaxillary .
