Prevalência de alterações locais e sistêmicas em indivíduos com disfunção temporomandibular

Temporomandibular disorder describes a variety of conditions including joint and muscle in the stomatognathic system, characterized by pain, TMJ sounds, functions irregular jaw and represent the leading cause of nondental pain in the orofacial region. The objective of this research was to evaluate the prevalence of ophthalmological, otological and cognitive-behavioral changes, parafunctional habits in individuals with temporomandibular disorders (TMD). A total of 117 medical records of female and male individuals, aged 18 to 60 years, from the Occlusion, Temporomandibular Dysfunction and Orofacial Pain of the Ribeirão Preto School of Dentistry – USP, between 2010 and 2011. The anamnesis index proposed by Helkimo was used to classify the individuals according to TMD severity degree and to divide them into two groups: AiI (mild to moderate) with 69 individuals and AiII (severe) with 48 individuals. The groups were then subdivided with respect to gender (72.64% female and 27.36% male) and age. There was predominance in the 18-40 year age group (60.68%) when compared to the 41-60 year age group (39.32%). Data were collected through an interview with questions about the presence of parafunctional habits, otological, ophthalmological and behavioral changes. Data were subjected to the statistical analysis using the Kruskal-Wallis test. The prevalence of each change was also evaluated. The results showed statistically significant for all groups according to gender, age and degree of severity. Individuals with temporomandibular disorders exhibited high prevalence of systemic and local dysfunctions.

Acupuntura em disfunção temporomandibular: relato de caso clínico

A técnica milenar da Acupuntura vem sendo empregada na Odontologia e obtendo bons resultados em diversas situações. Analgesia, relaxamento muscular e inflamação vêm sendo controlados, demonstrando assim conexão entre Acupuntura e redução de certas sintomatologias. As reações locais e à distância necessitam de correto posicionamento das agulhas assim como integridade do sistema nervoso, e são decorrentes da liberação de neurotransmissores (noradrenalina, acetilcolina, serotoninas e dopamina). Dentro da Odontologia, podemos nos utilizar dos seus efeitos no pré e pós operatório, em xerostomia, cefaléias, trismos, disfunção de ATM por estresse, parestesias, paresias, ansiedade, entre outras condições. Nos casos de disfunção de Articulação Temporomandibular por hiperatividade muscular, podemos utilizar a Acupuntura ao invés de relaxante muscular e antiinflamatório. Nesse trabalho, apresentaremos um caso clínico (paciente MCH, 23 anos, gênero feminino), a qual apresentava crises de dor de cabeça (região temporal), fazendo uso constante de medicação analgésica e antiinflamatória, o diagnóstico estabelecido foi Dor Muscular Local associado à hiperatividade muscular. Através do uso da Acupuntura, após aplicações semanais por 3 meses, houve remissão da dor por completo.

Prótese de palato em sujeitos com disfunção velofaríngea: expectativa e ansiedade

Cleft lip and palate (CLL) is a very common craniofacial anomaly. The cleft is usually corrected with surgery which may fail resulting in velopharyngeal dysfunction (VPD). The use of palatal prosthesis is an alternative treatment for correcting both, CLP and VPD. This study evaluated anxiety symptoms expectations of subjects of both genders, with velopharyngeal dysfunction, referred to palatal prosthesis program for VPD treatment. In this cross sectional and descriptive study 30 subjects with velopharyngeal dysfunction, aged 15 to 64 years old (mean age of 28) were interviewed at the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC). All subjects referred to the palatal prosthesis program at HRAC in the year of 2005 were considered for participation in the study but only the first 30 candidates were included. A questionnaire addressing expectation elaborated by the researcher and the Beck Scale on anxiety were used. All subjects showed expectation regarding speech modification. Changes in professional and affective aspects of their lives after changes in speech were obtained with palatal prosthesis were the most reported expectations. Subjects’ age and gender influenced anxiety levels significantly which were minimum across subjects. High levels of expectation were more frequent than anxiety in the sample population.

Indicadores diagnósticos da síndrome metabólica, butirilcolinesterase e estado de condicionamento físico em adolescentes obesos e eutróficos: uma breve explanação do atual estado da arte

Damage to health caused by excess body fat also generating a negative economic impact, with significant increase in public spending. The metabolic syndrome, which also gets several other names, such as plurimetabolic syndrome or syndrome X, is nothing more than the combined incidence of some diseases or metabolic disorders in which obesity, besides being one of them, seems to promote parallel effects that contribute to the development of other chronic diseases such as diabetes and cardiovascular disease. Researchers agree that hyper caloric diets associated with a sedentary lifestyle are the main triggers of disease, including the increasing on genetic predisposition to this disease in children and adolescents. In the case of children and adolescents the diagnosis is complicated by the lack of a consensus accepted by the scientific community. In addition to behavioral and environmental factors unfavorable to health, in a more detailed analysis also found hereditary aspects or simply genetic, such as hepatic enzyme Butyrylcholinesterase. When compared to eutrophic, obese adolescents, like adults obese, have higher serum concentration values as well as major activity for this enzyme. Increasing evidence suggests that excess body weight assumes an important role in the variation of metabolic functions in adolescents, favoring the emergence of early diagnostic indicators of metabolic syndrome.

Disfunção miocárdica e alterações no trânsito de cálcio intracelular em ratos obesos

Abstract Background: Several mechanisms have been proposed to contribute to cardiac dysfunction in obesity models, such as alterations in calcium (Ca2+) handling proteins and β-adrenergic receptors. Nevertheless, the role of these factors in the development of myocardial dysfunction induced by obesity is still not clear. Objective: The purpose of this study was to investigate whether obesity induced by hypercaloric diets results in cardiac dysfunction. Furthermore, it was evaluated whether this functional abnormality in obese rats is related to abnormal Ca2+ handling and the β-adrenoceptor system. Methods: Male 30-day-old Wistar rats were fed with standard food (C) and a cycle of five hypercaloric diets (Ob) for 15 weeks. Obesity was defined as increases in body fat percentage in rats. Cardiac function was evaluated by isolated analysis of the left ventricle papillary muscle under basal conditions and after inotropic and lusitropic maneuvers. Results: Compared with the control group, the obese rats had increased body fat and glucose intolerance. The muscles of obese rats developed similar baseline data, but the myocardial responsiveness to post-rest contraction stimulus and increased extracellular Ca2+ were compromised. There were no changes in cardiac function between groups after β-adrenergic stimulation. Conclusion: Obesity promotes cardiac dysfunction related to changes in intracellular Ca2+ handling. This functional damage is probably caused by reduced cardiac sarcoplasmic reticulum Ca2+ ATPase (SERCA2) activation via Ca2+ calmodulin kinase. (Arq Bras Cardiol 2011; 97(3) : 232-240).

Síndrome da disfunção cognitiva em cães

Cognitive dysfunction syndrome (CDS) is a progressive degenerative disorder of older dogs, characterized by a decline in cognitive function. The main clinical signs consistent with CDS are: disorientation, changes in socio-environmental interaction, sleep-wake cycle disturbance, changes in hygiene habits, urinate and/or defecate in unusual places, decreased physical activity, anxiety and eating disorders. There are no specific diagnostic tests for this condition in vivo, but alterations in neurological examination, cognitive tests and magnetic resonance imaging can be observed. The diagnosis is confirmed by histopathological examination of brain tissue. Diets rich in antioxidants, environmental enrichment with exercise and the use of selegiline and L-deprenyl have been recommended for the treatment of CDS.

Influência da temperatura e do termoperíodo sobre a taxa metabólica de repouso em cascavéis, Crotalus durissus (Serpentes: Viperidae)

Snakes are ectothermic animals and, therefore, their physiological functions are strongly affected by temperature. For instance, the resting metabolic rate (RMR) of this animals increase with the rise in body temperature. However, metabolic determinations in ectothermic organisms, including snakes, are generally made by submitting the animals to constant temperature regimes. This experimental procedure, although widely used, accepted and certainly suitable in several cases, submit the animals to a very different situation from that experienced by them in nature. In fact, ectothermics are known by presenting extensive variations in their body temperatures trough the day and/or seasons. If this disagreement between the thermal biology of the animals and the experimental conditions, for instance over the circadian cycle, affects the determinations of metabolic rates of ectotherm animals, remains quite uncertain. Thus, this study aimed to test the effects of different thermal regimes (fluctuating vs constant) in different temperature ranges over the TMR of rattlesnakes (Crotalus durissus). Therefore, the TMR of rattlesnakes was measured by the oxygen consumption rates ( V O2) in the constant temperatures of 15°C, 20°C, 25°C, 30°C and 35°C. For fluctuating regimes, snakes were measured in thermoperiods of 12/12 hours, as follows: 15°C and 25°C; 20°C and 30°C; 25°C and 35°C. Our results show that the RMR of C. durissus rises as the temperature increases, regardless of the thermal regime. The obtained RMR in the constant regimes of 20°C and 25°C was not different from that measured in the correspondent fluctuating regimes (i.e., 15 - 25°C e 20 - 30°C). However, at constant 30°C, the RMR was significantly higher than that obtained in the 30°C fluctuating regime (25 - 35ºC). This indicates that the potential effects in submitting of snakes to different thermal regimes of its thermal biology become more important with...
