Abstract: the term ameloblastic carcinoma is used to describe the ameloblastomas with histological characteristics of malignancy. this type of lesion may to occur in any age, but it may be more frequent observed in the fourth decade of life. the is not apparently a predominance sexual. the commonest involved area is the posterior portion of mandible involving in less extent the maxillary. this is a tumor with few cases mentioned in the literature, thus, the aim of present paper was to present a case of ameloblastic carcinoma in a female patient aged 38 came to consultation due to painful symptoms and facial asymmetry. in intrabuccal clinical examination it was noted a volume increase in the right posterior region of mandible. the computed tomography showed a slimming of the cortex with presence of a homogenous hypo-dense area. an incisional biopsy was made and its initial histological diagnosis was an ameloblastoma without histological characteristics of malignancy. after histopathological examination the surgical treatment of lesion was prescribed with a partial resection of mandible. the surgical structure (sample) was sent to laboratory to obtain a new diagnosis of ameloblastic carcinoma. it is probable that the difference of final histological diagnosis with the initial one could be related to the fact that the ameloblastic carcinoma has focal areas similar to ameloblastoma. after 6 months of surgical procedure the patient had tumoral lung metastasis and is under medical supervision.

Abstract: O termo carcinoma ameloblástico é usado para descrever ameloblastomas com características histológicas de malignidade. Les es desse tipo podem ocorrer em uma extensa faixa etária, sendo mais comum na quarta década de vida. N o há predile o aparente por sexo, a área mais comumente afetada é a por o posterior da mandíbula, envolvendo em menor propor o a maxila. Por se tratar de um tumor com poucos casos descritos na literatura, o objetivo deste trabalho foi relatar um caso de carcinoma ameloblástico em paciente do sexo feminino, 38 anos, com queixa de dor e assimetria facial. Ao exame clínico intrabucal observou-se um aumento de volume em regi o posterior de mandíbula, do lado direito. A tomografia computadorizada revelou adelga amento das corticais com presen a de área hipodensa homogênea. Foi realizada biópsia incisional cujo diagnóstico histológico inicial foi de ameloblastoma, sem características citológicas de malignidade. Baseando-se no exame histopatológico, optou-se pelo tratamento cirúrgico da les o através da ressec o parcial da mandíbula. A pe a cirúrgica foi encaminhada ao laboratório obtendo-se novo diagnóstico de carcinoma ameloblástico. Provavelmente, a diferen a do diagnóstico histológico final para o inicial pode estar relacionada ao fato de o carcinoma ameloblástico apresentar áreas focais semelhantes ao ameloblastoma. Após 6 meses da cirurgia, a paciente apresentou metástase tumoral no pulm o e encontra-se sob supervis o médica. El término carcinoma ameloblástico es utilizado para describir ameloblastomas con características histológicas de malignidad. Este tipo de lesión puede ocurrir en cualquier edad, pero se puede observar con mayor frecuencia en la cuarta década de vida. No existe aparentemente un sexo predominante. El área más comúnmente afectada es la porción posterior de la mandíbula y afecta en menor proporción el maxilar. Por ser un tumor con pocos casos relatados en la literatura, el objetivo de este trabajo fue presentar un caso de carcinoma ameloblástico en un paciente del sexo femenino con 38 a os de edad, que acudió a la consulta por presentar síntomas dolorosos y asimetría facial. Al examen clínico intrabucal se observó un aumento de volumen en la región posterior derecha de la mandíbula. La tomografía computadorizada mostró un adelgazamiento de las corticales con presencia de un área hipodensa homogénea. Fue realizada una biopsia incisional y su diagnóstico histológico inicial fue de un ameloblastoma sin características citológicas de malignidad.

Case Reports in Pathology , 2013, DOI: 10.1155/2013/725380
Abstract: The calcifying epithelial odontogenic tumor (CEOT) is a rare benign epithelial odontogenic neoplasm of slow growth that is locally aggressive and tends to invade bone and adjacent soft tissue. Here is reported the case of a 21-year-old female patient with a CEOT in the left mandibular posterior region. The computerized tomography in coronal plane revealed a hypodense lesion in the posterior region of the left mandibular body with hyperdense areas inside and was associated with element 37. An incisional biopsy of the lesion was performed and the histopathological analysis revealed the presence of layers of epithelial odontogenic cells that formed prominent intercellular bridges. A large quantity of extracellular, eosinophilic, and amyloid-like material and an occasional formation of concentric calcifications (Liesegang rings) were also found. The histopathological diagnosis was a Pindborg tumor. Resection of the tumor with a safety margin was performed and after 6 months of follow-up there has been no sign of recurrence of the lesion. 1. Introduction The calcifying epithelial odontogenic tumor (CEOT) or Pindborg tumor is a rare benign epithelial odontogenic neoplasm [1, 2], with approximately 200 reported cases in the literature [3]. In general it occurs as a slow-growing tumor [4], associated with an impacted tooth in the posterior mandibular region [5, 6]. This occurs predominantly between the fourth and fifth decades of life, with no preference of gender [2–4]. Radiographically, CEOT is characterized by a uni- or multilocular lesion that often shows a mixed radiolucent-radiopaque pattern [6]. Treatment consists in the surgical removal of the lesion, with recurrence in 14% of cases [5]. The prognosis is considered good [6]. 2. Case Report A 21-year-old black female patient sought treatment at the Oral and Maxillofacial Trauma Surgery Unit, with swelling in the mandibular left posterior region. While performing the intraoral physical exam an asymptomatic hardened exophytic nodule was found in region 37 (Figure 1). Figure 1: Intraoral aspect of the lesion, characterized by a hardened nodular and exophytic mass in the mandibular body, on the left side. The patient reported a clinical evolution of only five months of the lesion. A radiographic exam revealed a diffuse radiolucent, unilocular lesion, associated with region 37, yet including the distal root of region 36 up to the crown of region 38 (Figure 2). Using a computerized tomography in coronal section, it was possible to observe that it was a question of a local hypodense lesion in the mandibular

Creative Education (CE) , 2019, DOI: 10.4236/ce.2019.101012
Abstract: This article presents a brief history of distance education since its inception until present days, highlighting the correlations between that learning method and technological developments in the field of Education throughout the years. Furthermore, it aims at stressing that distance learning has always been a relevant subject in the field of education and is gaining ground all around the world once it is at the forefront of educational technology. Distance learning may enable learners to have widespread access to knowledge that they would not otherwise and, in this context, may keep alive the hope that teachers, students and educational public policies might converge so as to shape a promising future, especially in developing countries such as Brazil.

Abstract: urban violence has become a major concern for politicians, corporate managers and ordinary people, following social and environmental degeneration in the largest cities in brazil. in 1998, inter-american development bank estimated that the total costs of urban violence for the brazilian society were about 10,5% of the gross domestic product. the objective of this paper was to estimate, with the support of a hedonic prices model, the impact of criminal urban violence on the market price of residential real estate in the district of tijuca, city of rio de janeiro, brazil. two hedonic prices models have been used to evaluate both the impact of criminal violence in different districts of the city and the loss of value of houses and apartments due to the nearness of the slums in tijuca. main results were in accordance with common sense and previous studies. readers must be advised that the results are very preliminary, because of the well-known problems with both the data on the brazilian housing market and the hedonic prices model itself.

Abstract: OBJETIVO: Avaliar os resultados cirúrgicos dos pacientes com metástase vertebral secundária ao carcinoma de mama. MéTODOS: Vinte e duas pacientes operadas com doen a metastática vertebral secundária ao carcinoma de mama foram avaliadas no pré-operatório, pós-operatório imediato e depois de 1 mês e 6 meses do procedimento cirúrgico, usando a escala numérica da dor e o índice de incapacidade de Oswestry (ODI). RESULTADOS: As medidas para dor produziram valor de p de 0,0001 para a diferen a entre o pré-operatório e o pós-operatório imediato, 0,0005 entre o pós-operatório imediato e 1 mês de pós-operatório, e 0,0908 entre 1 mês de pós-operatório e 6 meses de pós-operatório, portanto, encontram-se evidências de diferen as entre o pré-operatório e o pós-operatório imediato, assim como entre o pós-operatório imediato e após o 1o mês, mas n o há tal evidência entre o 1o e o 6o mês de pós-operatório. Quanto ao ODI, a diferen a foi significativa em todos os períodos. CONCLUS O: A cirurgia melhora a dor e diminui a incapacidade dos pacientes com doen a metastática secundária ao carcinoma de mama. OBJETIVO: Evaluar los resultados quirúrgicos de los pacientes con metástasis vertebrales secundarias a carcinoma de mama. MéTODOS: Veintidós pacientes operados con enfermedad metastásica espinal secundaria a carcinoma de mama fueron evaluadas antes de la cirugía, inmediatamente después de la operación y después de 1 mes y 6 meses de la cirugía, mediante la escala numérica del dolor y el índice de discapacidad de Oswestry. RESULTADOS: Las medidas para el dolor produjeron un valor de "p" de 0,0001 para la diferencia entre el pre y postoperatorio, 0,0005 entre el postoperatorio inmediato y un mes después de la operación, y 0,0908 entre 1 mes después de la cirugía y el postoperatorio de 6 meses, por lo tanto, son la evidencia de las diferencias entre el pre y postoperatorio, así como entre el postoperatorio inmediato y después de un mes, pero no hay evidencia de tales diferencias entre 1 y 6 meses después de la operación. En cuanto al ODI, la diferencia fue significativa en todas las épocas. CONCLUSIóN: El procedimiento mejora el dolor y reduce la discapacidad en pacientes con enfermedad metastásica secundaria a carcinoma de mama. OBJECTIVE: To evaluate the surgical outcomes of patients with spinal metastasis secondary to breast carcinoma. METHODS: Twenty-two patients operated spinal metastatic disease secondary to breast carcinoma were assessed preoperatively, immediately postoperatively and after 1 and 6 months of surgery, using the numerical scale of pain and Oswestry Disa
