Relationship between temporomandibular disorders and orthodontic treatment: a literature review

OBJETIVO: revisar a literatura mais atual, dos últimos 15 anos, em busca de estudos clínicos que relatem a relação entre a disfunção temporomandibular (DTM) e o tratamento ortodôntico e/ou a má oclusão. A intenção foi verificar se o tratamento ortodôntico aumentaria o aparecimento de sinais e sintomas de DTM, e se o tratamento ortodôntico seria um recurso para o tratamento ou prevenção dos sinais e sintomas de DTM. MÉTODOS: artigos dos tipos revisão de literatura, editorial, carta, estudo experimental em animais e comunicação foram excluídos dessa revisão. Foram incluídos artigos prospectivos, longitudinais, caso-controle ou retrospectivo com amostra maior, com relevante análise estatística. Estudos que abordassem deformidades e síndromes craniofaciais e tratamento por cirurgia ortognática também foram excluídos, bem como aqueles que relatassem apenas a associação entre má oclusão e DTM. RESULTADOS: foram encontrados 20 artigos relacionando Ortodontia à DTM, segundo os critérios adotados. Os estudos, então, associando sinais e sintomas de DTM ao tratamento ortodôntico apresentaram resultados heterogêneos. Alguns encontraram efeitos positivos do tratamento ortodôntico para os sinais e sintomas de DTM; entretanto, nenhum deles apresentou diferença estatisticamente significativa. CONCLUSÕES: todos os estudos citados nessa revisão de literatura relataram que o tratamento ortodôntico não forneceu risco ao desenvolvimento de sinais e sintomas de DTM, independentemente da técnica utilizada para tratamento, da exodontia ou não de pré-molares e do tipo de má oclusão previamente apresentada pelo paciente. Alguns estudos realizados com acompanhamento em longo prazo concluíram que o tratamento ortodôntico não seria preventivo ou uma modalidade de tratamento para DTM.

Blindness after laryngectomy and bilateral neck dissection in a diabetic patient: case report

CONTEXTO: O esvaziamento cervical que acompanha a ressecção da lesão primária no tratamento dos tumores malignos das vias aerodigestivas superiores possibilita o surgimento de complicações inerentes a ela ou ao prolongamento do tempo cirúrgico, aumentando os riscos para o paciente. Entre as complicações que podem ocorrer está a amaurose, de incidência rara. RELATO do CASO: Um paciente submetido a laringectomia total e esvaziamento cervical seletivo à esquerda e radical modificado à direita, que evoluiu com amaurose, provavelmente decorrente de hipotensão intra-operatória, com contribuição dos Diabetes Mellitus descompensado e trombose da veia jugular interna à direita. Discutem as possíveis causas, os fatores de risco e os cuidados que devem ser tomados para evitar essa rara, mas tão debilitante complicação.

Complete atrioventricular block during renal transplantation in a patient with Alport's syndrome: case report

CONTEXTO: A síndrome de Alport é responsável por aproximadamente 5% dos pacientes com insuficiência renal crônica. Nessa doença, anormalidades no sistema de condução cardíaco são mais freqüentes que na população em geral. OBJETIVO: Relatar caso de síndrome de Alport que desenvolveu bloqueio atrioventricular total durante um transplante renal. RELATO DE CASO: Paciente masculino, 21 anos de idade, com insuficiência renal crônica secundária à síndrome de Alport, foi submetido a transplante renal sob anestesia peridural. Durante o procedimento anestésico-cirúrgico apresentou bloqueio atrioventricular total, que foi tratado rapidamente, e com sucesso, usando-se um marcapasso transcutâneo. O bloqueio simpático extenso pode contribuir para o desenvolvimento de distúrbios no sistema de condução cardíaco, particularmente em pacientes com insuficiência renal crônica em esquema de diálise. Mesmo em pacientes com eletrocardiograma pré-operatório normal e sem distúrbios de condução, graus variáveis de bloqueio atrioventricular, incluindo bloqueio atrioventricular total, podem ocorrer. Nesse caso, o uso de marcapasso transcutâneo é tratamento rápido e efetivo na sala de operação até o final da cirurgia, quando o tratamento definitivo pode ser planejado.

RELATIONSHIP BETWEEN PLASMA 17-BETA ESTRADIOL ON THE DAY OF ESTRUS AND NUMBER OF VIABLE EMBRYOS IN BOS-INDICUS (NELLORE) COWS SUPEROVULATED WITH FSH

Thirteen cows, Bos indicus, of the Nellore breed were superovulated with 22 mg of follicle stimulating hormone (FSH) administered by intramuscular route during four consecutive days (D10, D11, D12 and D13), starting on the 10th day of the estrous cycle (day 0 = estrus). Prostaglandin (PGF2alpha, 1.0 mg, im) was administered on D12, 48 h after the first FSH injection, for the induction of estrus on D14, when artificial insemination was performed. Seven days later (D21 of the cycle), embryos were collected, and evaluated, and the ovarian response was estimated on the basis of number of corpora lutea determined by rectal palpation. Blood samples were obtained for the determination of plasma 17-beta estradiol on D10, D11, D12, D13, D14 and D21 and plasma progesterone on D14 by RIA. The donors were divided into two groups according to progesterone levels on D14, the day of the induced estrus (GI: P4 less-than-or-equal-to 1.00 ng/ml, N = 5 and GII: P4 > 1.00 ng/ml, N = 8). A linear positive correlation was observed between plasma 17-beta estradiol concentration on the day of estrus and viable embryo number. We conclude that plasma 17-beta estradiol and progesterone concentrations on the day of estrus can be used to predict the viability of embryos recovered from Nellore cows superovulated with FSH.

Relationship between lower-lip fistulae and cleft lip and/or palate in Van der Woude syndrome

Objective: This study was conducted to evaluate the relationship between fistulae of the lower lip and cleft lip and/or palate in patients with Van der Woude syndrome.Methods: the medical records of 11,000 patients with cleft lip and/or palate registered at the Cleft Lip-Palate Research and Rehabilitation Hospital, University of São Paulo, Bauru were reviewed. of these patients, 133 (1.2%) presented with Van der Woude syndrome.Results: of the 133 patients, 88 (66.2%) exhibited full clefts, 22 (16.5%) only cleft lip, and 23 (17.3%) only cleft palate. The lower-lip fistulae observed in these 133 patients were bilateral symmetric in 66 (49.7%), bilateral asymmetric in 42 (31.6%), microform in 19 (14.3%), median in 5 (3.8%), and unilateral in 1 (0.7%).Conclusion: This population sample appears to exhibit the previously published tendency for bilateral, unilateral, or mixed-type congenital fistulae to be associated with cleft lip with or without cleft palate, while so-called microforms or conic elevations are almost exclusively associated with cleft palate.

O processo de trabalho em ambulatorio de saude mental

This study was carried out to evaluate the working procedures of the mental health at the medical and administrative team at the mental health outpatient unit in Botucatu, attempting to understand its previous and social characteristics in relation to psychiatry, health and Brazilian society. The objective of this study was to analyze the activities being used and the professional inter-relationship of the team. It tried to identify the main factors that controlled the actions, the social needs are attended to. Direct observation and interviews focused on the patients and workers were the methods used. The results were reviewed in the lights of the concepts of 'work technological organization' and 'working process' which enabled the identification of the units of work at the center. After all, it was noticed that there were two distinct trends of work organization: one of them aimed at individual treatment by medical staff and the other aimed at group treatment by non-medical staff.

Psychiatric disorders and psychiatric consultation in a general hospital: A case- control study

Introduction: Psychiatric consultation (PC) has been considered an efficient tool to develop research, to track and to give assistance benefiting patients, health professionals and the institution. However, it has not been much used in Brazil. Although 30 to 50% of general hospital (GH) inpatients may present a psychiatric disorder, only 1 to 12% of them are referred to assessment. The aims of this study were: to assess mental disorders in a GH; to identify which of these patients are sent to psychiatric care; to verify alleged reasons for referral to psychiatric consultation, and to examine the relationship between PC and psychiatric learning (during medical school and residence). Methods: A case-control patient study was conducted (47 cases and 94 controls) to analyze in detail the following variables: socio-demographic; clinical; degree of information (about the disease and diagnostic/therapeutic procedures), and relationship between patient and health team. Psychiatric diagnoses were made according to the ICD- 10 criteria. The Self Report Questionnaire (SRQ), the CAGE and Brief Psychiatric Rating Scale (BPRS) were used as well as a specifically designed questionnaire to collect clinical and demographic data. Results: Behavioral alterations, either of elation or of depression, were the main for requesting a PC; 95.8% of the cases and 27.7% of the controls had a mental disorder. Organic mental disorders and alcohol-related disorders were the most frequent diagnoses in group I (cases), while anxiety, depressive and alcohol-related disorders were predominant in group II (controls). Control group patients were better informed and more able to establish an appropriate relationship with the health team than case patients. The logistic regression showed CAGE-positive patients having 12.85 times greater risk of being referred to PC, followed by unemployed patients (2.44 times more PC referrals). Discussion: The SRQ and CAGE were quite useful in the screening of possible patients and might be important for medical students to learn and use as generalists. Further research is needed to verify if and how the newly-established service will improve the diagnostic and treatment skills of our students.

A preliminary report on the effect of laser therapy on the healing of cutaneous surgical wounds as a consequence of an inversely proportional relationship between wavelength and intensity: Histological study in rats

Objective: The objective of the present investigation was to assess the histological effects of different wavelengths and intensities on the healing process of cutaneous wounds. Background Data: Tissue repair is a dynamic interactive process which involves mediators, cells and extra-cellular matrix. Several reports on the use of laser therapy have shown that the healing process is positively affected when the correct parameters are used. Methods: Eighteen standardized wounds were surgically created on the dorsum of male and female Wistar rats, which were subsequently divided into two experimental groups according to wavelength used λ.670 or λ685 nm) for lasertherapy (LLLT). Each group was divided into three subgroups of three animals according to the intensity of the applied irradiation (2,15, or 25 mW). Twelve animals were used as entreated controls and were not irradiated. The irradiation was carried out during seven consecutive days. The animals were sacrificed eight days after surgery. The specimens were removed, kept in 4% formaldehyde for 24 h, routinely prepared to wax, stained with H&E, and analyzed under light microscopy. Results: For both groups, light microscopy showed a substitution repair process; however, when LLLT was used, a positive biomodulatory effect was detectable, chiefly associated with shorter wavelength and low intensity. Conclusions: The results of the present study indicate that LLLT improved cutaneous wound repair and that the effect is a result of an inversely proportional relationship between wavelength and intensity, with treatment more effective when combining higher intensity with short wavelength or lower intensity with higher wavelength.

Multiplicadores reflexivos: Uma experiância do Instituto Familiae junto ao Grupo de Assistância em Transtornos Alimentares (GRATA) do HC-FMRP-USP

This article describes the Reflecting Practitioners Program developed by Instituto Familiae at GRATA (Grupo de Assistência em Transtornos Alimentares) placed at the Clinical Hospital of the Faculty of Medicine of Ribeirão Preto - University of Sao Paulo (HC-FMRP-USP). The aim of this program was to take care of the caretakers - the GRATA interdisciplinary team - through the development of their reflecting ability, the appropriation of their own resources and the support on constructing alternative histories and on solving situations defined by them as problematic. Thirteen monthly meeting had been carried out among Familiae members and GRATA interdisciplinary team. The changes described by the participants had occurred through sessions developed with interdisciplinary pairs and through the development of their capacity to construct more comfortable positions - as members of the team and in the relationship among professional/client/ family. This triad became to be seen by the team through its resources and abilities, instead of its flaws and lacks. As a result, horizontal relationships could be privileged instead of hierarchical ones.
