La relación entre la calidad de la enseñanza y la mala práctica odontológica: relato de caso clínico

Las actividades desarrolladas en el área de la salud son de gran importancia, pues tienen como finalidad preservar la vida de los individuos y para eso deben ser desempeñadas por personas habilitadas. El aumento del número de facultades de Odontología, la disminución en la calidad de la enseñanza y el mayor ingreso de alumnos con baja capacidad para ejercer la profesión son hechos que traen consecuencias desastrosas para la sociedad. Estos hechos también se reflejan en el desempeño moral, ético y técnico-científico del profesional. El objetivo de ese relato de caso clínico es enseñar que, aunque hay una considerable oferta de instituciones de enseñanza, existe un desconocimiento científico y de técnicas adecuadas por parte de los cirujanos dentistas graduados. La paciente MSL, 17 años, sexo femenino, compareció al consultorio odontológico usando un molde tipo Vernis, sujeto al arco inferior. Tras evaluación clínica, se observó la utilización de un material incorrecto para la toma de impresión, siendo imposible su retiro con el método convencional. La planificación para su retiro se hizo por medio de seccionamiento. De esta manera, la consecuencia de la falta de conocimiento en el uso de materiales para la impresión causó gran trastorno a la paciente. Se puede concluir que el índice de impericia está relacionado directamente con la formación profesional, evidenciando la importancia de la enseñanza odontológica de calidad para una práctica clínica responsable.

Estudiar economía y racionalidad: un experimento

En este documento se lleva a cabo el mismo experimento realizado por Harbaugh et al. (2001) usando como sujetos en el experimento a estudiantes de economía, ciencias políticas y medicina, quienes tienen una fuerte, mediana y nula formación en economía. El objetivo es encontrar violaciones al axioma débil de preferencia revelada (ADPR) y medir la magnitud de las violaciones mediante el calculo del índice de Afriat. Después de la evaluación de los resultados del experimento encontramos que un entrenamiento exhaustivo y medio en economía genera básicamente los mismos resultados en términos de la violación al ADPR, y que ningún entrenamiento en economía implica un considerable numero de decisiones erróneas en términos económicos.

Comunicar com símbolos em contexto inclusivo : aplicação de software educativo

O presente estudo de investigação-ação partiu da necessidade de investigar e aprofundar a aprendizagem do mecanismo da leitura e da escrita numa criança com Paralisia Cerebral mediante a aplicação do software educativo “Comunicar com Símbolos”. O trabalho desenvolveu-se inicialmente num Centro Escolar de um Agrupamento de Escolas da zona centro do país, no distrito de Santarém, passando a realizar-se, após avaliação diagnóstica, numa Instituição Particular de Segurança Social - Centro de Deficientes Profundos da mesma região e analisa essencialmente o desenvolvimento da aprendizagem da leitura e da escrita numa criança com Paralisia Cerebral Espástica Bilateral com predomínio nos membros inferiores através da aplicação de dez sessões planificadas com base na utilização do software educativo Comunicar com Símbolos, da Cnotinfor – Imagina. Após a intervenção e a análise dos resultados, concluiu-se que o programa informático supramencionado apresenta vantagens significativas na consolidação da leitura e da escrita da criança com Paralisia Cerbral. Este trabalho de natureza interventiva não pretende, de forma alguma, dar respostas únicas na implementação de estratégias na melhoria do desenvolvimento do mecanismo da leitura e da escrita em crianças com Paralisia Cerebral, mas apenas contribuir para uma reflexão aprofundada sobre a importância da aplicação das tecnologias de apoio na prática pedagógica com crianças com Necessidades Educativas Especiais, no geral.

Beyond to APO s implements were applied behavior setting s techniques too, what presented the most knowledge about to satisfactions levels pointed by the users

Cosmoeducação: uma abordagem transdisciplinar no ensino de astronomia

This work proposes a transdisciplinary approach that integrates transpersonal psychology exercises with astronomy teaching, seeking to allow one to reintegrate the sky in his/her daily life, expand his/her environmental awareness and eventually experiment the unity between human and cosmos. This proposal intends to collaborate with the supplying of education, which lacks initiatives of this kind, with the promotion of an integration of the scientific knowledge with the human experience that transcends the materialistic and fragmentary objectives of the current educational system. As a result of that lack, the teachers formation is also poor as for an integral and transdisciplinary approach. Besides, we also approached in this research the necessity to propose alternatives so that the educators may work in a more assertive way with the environmental and anthropological crisis in which we are living. Our working hypothesis is that the contents of astronomy, when they are dealt in a holisticanthropological focus and are related with transpersonal psychology practices, can come to be an efficient cultural-academic vehicle, capable of propitiating an expansion of consciousness and changes in the way one conceives the world. Such changes are necessary so that a more solidary, fair and ecologically balanced life may come to exist and prevail in the planet. Part of the collection of data was done through the ethnographic method, once an anthropological interpretation is inextricably associated with this kind of educational intervention, which will naturally include ethno-visions of the universe as well as specific cultural elements. In the beginning the scope of this research was a group of students attending the Astronomy assignment in an undergraduate Geography course (UFRN), in which we accomplished participant observation, half-open interviews and the first experimental practices mentioned. After the evaluation of the first data collected from that initial group, we elaborated an academic extension course, Laboratory in Cosmoeducation, and we offered it to teachers of the 1st and 2nd cycles of the fundamental level of the Alceu Amoroso Lima State School, located in the North Zone of Natal. We prized self-experimentation in that course, so that the teachers could enrich their repertoire of personal experiences, stimulating meditative reflections and eventual changes in the ways of conceiving the world and in their pedagogical practice. The transdisciplinary attitude permeated all our educational action, because this approach transcends the boundaries of disciplines, seeking essentially the integral development of the human being. The process has made us realize that the practice of looking at the sky , as a way of reintegrating it into daily life, provokes a process of expansion of the consciousness and of reintegration of the self in a wider level of environmental interrelation. According to the results, the occurrence of conceptual and existential changes of the world vision of the participant teachers was evident, reassuring ourselves of the idea that the interface between astronomy teaching and the practices of transpersonal psychology can contribute to the recovery of a holistic relationship between the human being and the cosmos and to inspire the arising of a more wide-ranging ethics, based on universal, impartial and sustainable values

Influência da fisioterapia complexa descongestiva associada à ingestão de triglicerídeos de cadeia média no tratamento do linfedema de membro superior

OBJETIVO: Verificar a influência da utilização da fisioterapia complexa descongestiva associada à dietoterapia com triglicerídeos de cadeia média (TCM) como forma de intervenção no linfedema de membro superior (MS). MÉTODOS: Para a avaliação do linfedema, foram utilizadas cirtometria, volumetria, pregas cutâneas e quantidade de água corporal total. A Escala Visual Análoga (EVA) foi utilizada para avaliar as sensações de desconforto, peso e dor no MS. Participaram deste estudo dez mulheres mastectomizadas com linfedema de MS homolateral à cirurgia, com idade média de 65,9 ± 10,4 anos e índice de massa corpórea (IMC) de 26,8 ± 3,0kg/m² que, após avaliação nutricional, foram divididas aleatoriamente em dois grupos: Grupo Controle (n= 5), submetido ao tratamento fisioterapêutico constando da terapia complexa descongestiva (massagem clássica, drenagem linfática manual, bandagem compressiva e cuidados com a pele) três vezes na semana, durante quatro semanas; Grupo TCM (n= 5), submetido ao mesmo protocolo fisioterapêutico somado ao tratamento dietético diário com ingestão de TCM, por quatro semanas. RESULTADOS: Ao final da intervenção, a análise da cirtometria e da volumetria mostraram diferenças significativas entre os grupos (< 0,05), com maior redução do linfedema no Grupo TCM. Não houve diferença significativa nos valores das pregas cutâneas e da quantidade de água corporal total. A sensação de peso no membro superior, antes e após a intervenção, foi significativamente menor (< 0,05) no Grupo TCM. CONCLUSÕES: O tratamento fisioterapêutico somado à dietoterapia com ingestão de TCM em mulheres portadoras de linfedema de MS pós-cirurgia e tratamento de câncer de mama foi efetivo na involução desta condição.

Use of radiograph optical densitometry to monitor bone quality in broiler breeders

This study was carried out at Faculdade de Medicina Veterinária e Zootecnia, Universidade Estadual Paulista, Botucatu, SP, Brazil, and evaluated bone quality in broiler breeders. Twenty-three families of Ross broiler breeders were housed in 5.0-m² pens. The families were comprised of 13 females and one male at the onset of the experimental period. The mean number of females per family was 9.34 at the end of the trial. The feeding program and management followed strain guidelines (Agroceres Ross, 2003). Bone analyses were performed in the right tibia and femur using optical radiographic densitometry at 4, 8, 12, 15, 20, 24, 30, 35, 42, 47 and 52 weeks of rearing. Trap nests were used to collect eggs from the breeders two weeks before and after the evaluation weeks. At each evaluation day, five birds were sacrificed after radiographs were taken and the tibias and femurs were collected to perform the following analyses: fatfree dry matter, ash percentage, bone resistance and Seedor index. Therefore, it was possible to establish correlations between bone quality and eggshell quality. Characteristics of bone quality were highly correlated to each other; on the other hand, there were no correlations between bone quality and external egg quality. In conclusion, there was no effect of egg production on egg quality, possibly because there was no reabsorption of bone minerals.

Foreign Body in Preauricular Region

Foreign bodies, although they are often found throughout the body, to a lesser degree in the face, still constitute a diagnostic challenge for the trauma surgeon. Its removal means danger of damaging important facial anatomic structures, even if its exact position from the image data was known. So, the objective is to describe a clinical report of a patient (42 years of age, male sex) who experienced falling to the ground, attended by the Department of Surgery and Traumatology Bucco-Maxillo-Facial Surgery, Faculty of Dentistry of Aracatuba, São Paulo State University, and 2 days after the trauma, he reported difficulty in mouth opening and pain. After clinical evaluation, we observed the presence of injury in the left preauricular region already in the process of healing. During the intraoral physical examination, a limitation of the mouth opening was noted. Radiographic posteroanterior and profile of the face showed 2 radiopaque foreign bodies in the left side, lying apparently at the region of the mandibular condylar process. Under local anesthesia, foreign body removal was carried from there with access to it through the preexisting facial injury. Further clinical examinations showed an improvement in mouth opening, absence of pain complaints, and/or functional complaints.

doi: 10.1111/j.1741-2358.2012.00636.x Hyperbaric oxygen therapy treatment for the fixation of implant prosthesis in oncology patients irradiated Objectives: This study aimed to present a clinical report of an irradiated oncologic patient who underwent hyperbaric oxygen therapy to be rehabilitated with implant-supported prosthesis. Materials and Methods: A 67-year-old man was admitted at Oral Oncology Center (FOA-UNESP) presenting a lesion on the mouth floor. After clinical evaluation, incisional biopsy and histopathological exam, a grade II squamous cell carcinoma was diagnosed. The patient was subjected to surgery to remove the lesion and partial glossectomy. Afterwards, the radiotherapy, in the left/right cervicofacial area of the supraclavicular fossa, was conducted. After 3 years of the surgery, the patient was submitted to hyperbaric oxygen therapy. Then, four implants were installed in patients mandible. Five months later, an upper conventional complete denture and lower full-arch implant-supported prosthesis were fabricated. Conclusion: The treatment resulted in several benefits such as improving his chewing efficiency, swallowing and speech, less denture trauma on the mucosa and improving his self-esteem.

Relação entre o índice de massa corporal e a gravidade da asma em adultos

OBJETIVO: O aumento do índice de massa corporal (IMC) tem sido associado a uma maior prevalência da asma em adultos. O presente estudo tem o objetivo de avaliar a associação entre a prevalência da obesidade e a gravidade da asma. MÉTODOS: Prontuários de duzentos asmáticos acima dos 20 anos de idade foram avaliados retrospectivamente. A asma foi classificada quanto à gravidade através da história clínica e do diagnóstico registrados, dos resultados da espirometria e da medicação prescrita. O IMC foi calculado e foram considerados obesos os pacientes com IMC > 30 kg/m². RESULTADOS: 23% dos pacientes apresentavam asma intermitente, 25,5%, asma persistente leve, 24%, asma persistente moderada e 27,5%, asma persistente grave. O IMC < 29,9 kg/m² foi observado em 68% dos pacientes e em 32% o IMC foi > 30 kg/m². O odds ratio da relação entre a obesidade e a gravidade da asma foi de 1,17 (CI95%: 0,90-1,53; p > 0,05). CONCLUSÕES: Na amostra estudada não foi encontrada correlação entre a obesidade e a gravidade da asma nem no sexo masculino, nem no feminino.

Developmental lead exposure induces depressive-like behavior in female rats

The involvement of neurotoxicants in the etiology of emotional pathologies is becoming an issue in neurotoxicology. Lead (Pb) exposure during childhood has been associated with increased impulsivity, aggressivity, and delinquency. Considering the paucity of experimental studies investigating the involvement of developmental Pb exposure in emotional disorders, our objective was to investigate whether Pb exposure during pregnancy and/or lactation could be related to depressive symptoms in adult male and female rats. Wistar dams received 10 mg of Pb, as Pb acetate, or 13.4 mg of Na acetate, by gavage, daily, during pregnancy and lactation. By cross-fostering at the time of birth, pups were either exposed to Ph or Na acetate during pregnancy only, lactation only, or during both pregnancy and lactation. At 70 days of age, animals were submitted to the open-field test followed by the forced swimming test. Ph levels were measured in the blood of dams (weaning) and pups (after behavioral evaluation). The results demonstrated that exposure to Ph during both pregnancy and lactation induced, in males, an increased emotionality state detected in the open-field test, and in females, depressive-like behavior detected in the forced swimming test. These alterations were observed at residual blood Pb levels (i.e., around 5 mug/dL).

Low-grade endometrial stromal sarcoma presenting as vaginal nodule

Endometrial stromal sarcoma is a rare neoplasm of the uterus. Extrauterine locations of this neoplasm, excluding metastases or local extension, are even more unusual and are usually associated with the presence of endometriosis. The authors report a case of endometrial stromal sarcoma presenting as a vaginal wall nodule, without any sign of primary uterine tumor after extensive evaluation or presence of endometriosis. The morphology, immunohistochemical profile, differential diagnoses, and pathogenesis are discussed, as well as a review of the literature on this issue. © 2004 Elsevier Inc. All rights reserved.

Utilização do primeiro ciclo ovulatório da estação reprodutiva para produção de embriões em éguas sob condições tropicais

The efficacy of the first ovulation of the breeding season was determined through the response of first pre-ovulatory follicle of the breeding season to hCG, embryo recovery rate, viability of recovered embryos, serum concentrations of progesterone, and response of first CL to PGF 2α. Thirteenth mares that were in vernal transition were accompanied until the first pre-ovulatory follicle was detected. At this moment, the ovulation was induced with 2,500 IU hCG (IV) and the mares were inseminated every other day until ovulation. Seven days after the ovulation, embryo recovery was performed and the progesterone concentration was determined. After detection of the first pre-ovulatory follicle of breeding season with ≥ 25mm, it took 14.92 ± 10.80 days for the follicle to reach the preovulatory size and 18.00 ± 11.08 days to ovulation. After administration of hCG, 11/13 mares ovulated in 48 hours. These follicles growth 2.19 ± 0.86 mm/day on average. Nine of 13 mares (69.2%) produced embryos and all were considered viable after morfological evaluation and fluorescence exams. The CL appeared competent producing 7.39 ± 2.11 ng/ml P 4 on average, and responding to PGF 2α. According to these results the first ovulatory cycle of the year can be utilized to produce viable embryos.

Proteômica para investigar a congelabilidade do semen bovino

The present study was undertaken the protein composition in 2D-electrophoretic pattern (2DE) of the seminal plasma (SP) can interfere in the semen bull freezability, and if we can use that for predicting semen bull freezability. Samples were obtained of 20 bulls (different breeds) with a minimum of 3 years history semen production in commercial semen collection Center. All animals ranged between 2 - 7 years of age. The semen freezability was calculated by # of thawed and approved ejaculates / # of ejaculates submitted to cryopreservation (after semen evaluation and approved to submitted to freeze). The bulls were divided in 3 groups: HIGH (=>80% ejaculates approved); MEDIUM (>60% and <79% ejaculates approved); LOW (=<59% ejaculates approved); the pattern and criteria were the same used in the routine of the commercial semen Center. 68 gels were carried through by 2DE of SP samples indicated 225 detected spots with protein different amount (VION) comparing. Comparing bull ́s semen freezability and VION of each spot found difference among 2 spots from High and Low, even considering just spots with % of detection frequency bigger than 75%. The taurine bulls demonstrated more homogeneous profile when comparing with zebu bulls, considering number and frequency of appearance of spots. The results showed that proteomics can be a useful tool to predict the semen freezability, but we ́ll need to study better the interactions between sperm membrane, seminal plasma and extender to comprehend better which proteome phenotype interfere positive or negatively in the semen freezability.
