Estudo da correlação da densitometria óssea e do perímetro diafisário medial do terceiro metacarpiano em equinos

In this study, 14 post mortem equine metacarpal bones were evaluated to correlate the medial III metacarpus perimeter to dorsal bone density of the same region using Computed Tomography and Quantitative Ultrasound (QUS). According to Pearson's test, there were not correlations between these variables. Considering there are few bone densitometry studies in horses and there are many variables that can interfere with bone mineralization, new studies on equine bone density applying standard variables are recommended.

Determinação da densidade mineral e da elasticidade óssea após a aplicação de ondas de choque extracorpóreas no terceiro metacarpiano de equinos atletas

The porpoise of this study was to evaluate the effects of extracorporeal shock waves in third metacarpus bone from healthy horses by determination of bone elasticity. It were used 20 Thoroughbred horses, male and female, with two years old, on top of training and selected as the state healthy. At the beginning of the experiment (D0), all animals were submitted for evaluation of bone elasticity held in the third metacarpus bone. The animals were divided into two groups (Control Group - CG and Experimental Group - EG). The application of extracorporeal shock wave therapy (ESWT) was performed on the right forelimb of the animals in the experimental group in the same place evaluated for bone elasticity and was used apparatus for extracorporeal therapy of waves with 0.15 mJ/mm2 energy flux density and 2000 pulses with E6R20 probe, with focus feature of the shock wave of 20 mm. The ESWT were repeated every 21 days, a total of three sessions (D0, D21 and D42). The analysis of bone elasticity determination was realized at D21, D42 and D72. The average of speed ultrasound differed between groups at D21, D42 and D72, and the animals from EG had lower bone mineral density after applications of ESWT. There was also difference in the analysis of bone mass (Z-Score) between the groups at D21 and D42, which animals from EG showed a significant decrease in bone mass. The risk of fracture was higher in animals from experimental group at D21. It was concluded that ESWT is able to promote change in bone mineral density.

Cisto coloide no terceiro ventrículo e morte súbita em jovem

Morte súbita de jovem, sexo masculino, 23 anos, assintomático, suscitou verificação de óbito. Antes queixou-se de cefaleia excruciante, em sala de aula, caindo sobre o computador. Encéfalo apresentou edema e congestão vascular. Sem herniações. Cortes coronais evidenciaram dilatação dos ventrículos laterais e nódulo aderido ao teto do terceiro ventrículo. À microscopia o diagnóstico foi cisto coloide do terceiro ventrículo. A ameaça de morte súbita em portadores de cisto coloide é sério problema diagnóstico na emergência médica. A relevância deste caso está em lembrar aos médicos que esta entidade deve permanecer como diagnóstico diferencial nas cefaleias em crianças, adolescentes e adultos jovens.

Glioma cordoide do terceiro ventrículo: descrição de um novo caso

O glioma cordoide é um tumor cerebral raro, recentemente descrito, localizado na região do terceiro ventrículo e com características histológicas, imuno-histoquímicas e ultraestruturais peculiares. Este estudo ilustra um caso de glioma cordoide do terceiro ventrículo em uma paciente de 59 anos de idade.

As escolas vocacionais e o terceiro ambiente de Hargreaves

The article refers to an official school experience which was developed in the Brazilian education in the 60's - the vocational schools. These schools enabled an artistic-musical learning experience which would be less technicist and autocratic, contributing in a satisfactory way to the future performing formation of the students. In addition to the historical report, the text refers to the British educator D. Hargreaves, who researched on the importance of the "third environment" in the musical learning and on the relationship existing between the internal and the external cognitive process. The text is part of the Master or Arts dissertation which is being carried out in the IA-UNESP (Institute of Arts - State of São Paulo University). The musical-theoretical foundations were provided by the ideas of D. Hargreaves, Sigurd Rascher, Yehudi Menuhi, among others, and by some researchers in the area of education. It is justified on the grounds of the present moment experienced by the musical teaching in face of the approval of Law n(o) 11.769/2008.

Importância da região anteroventral do terceiro ventrículo (AV3V) no controle cardiovascular e do equilíbrio hidroeletrolítico

The maintenance of the arterial pressure in normal levels is important for the homeostasis of body fluids. The central nervous system regulating sympathetic and parasympathetic autonomic efferent can adjust arterial pressure which allows animals or human to face different daily activities with the best performance. Different central areas are responsible for the control of autonomic discharges to cardiovascular system and many of them are also involved in the control of fluid electrolyte balance. One of these areas is the tissue surrounding the anteroventral third ventricle (AV3V region) localized in the forebrain and a main central site for angiotensin II receptors and osmoreceptors. The AV3V lesions impair the development of many models of experimental hypertension in rats and the pressor responses to different stimuli. Lesions of the AV3V region also reduce dipsogenic responses to angiotensin II, central cholinergic activation, water deprivation and increase in plasma osmolarity, atrial natriuretic peptide secretion produced by body fluid expansion and the increase in renal excretion to central cholinergic activation. Recent evidence also suggests the participation of AV3V region in pressor responses produced by the activation of medullary mechanisms.

Transformação cística como consequência de terceiro molar inferior incluso

The permanence of impacted third molar in the jaws can cause many pathological alterations, amongst them the appearance of odontogenic cysts. The paradental cyst appearance and evolution next to a mandibular included third molar was diagnosised in radiograph routine follow-up, and its evolution and treatment are described. Are discussed the aspects related with the preventive removal to the impacted third molars and the necessity to institution a plan of treatment based in clinical history and radiograph in order to establish a preventive protocol the alterations caused by these impactions. The indication of extraction of impacted third enclosed can be a way to preventing the appearance of these and otherspathologies associates to these lesions.

Tumor maligno da bainha de nervo periférico envolvendo raízes nervosas do terceiro segmento medular lombar em um cão

Malignant peripheral nerve sheath tumors (MPNST) involving spinal nerve roots are uncommon in dogs. A nine-year old, intact, mixed-breed dog, demonstrated clinical signs of incoordination in the pelvic limbs and micturition for approximately one week. Clinical examination revealed proprioceptive deficits and bilateral patellar hyperreflexia. During exploratory celiotomy a mass was observed adhered to the lumbar vertebral segments. Medical therapy was initiated, but neurological signs were progressive, and the owner opted for euthanasia. Gross examination showed that the mass in the abdominal cavity was attached to the lumbar segments L3 and L4, causing bone lysis in L3, but showed no tumor invasion into the spinal canal. Microscopic features were characterized by prominent proliferation of ovoid and fusiform cells with poorly defined cytoplasm arranged in interlacing bundles and concentric whorls. The cells were embedded in a delicate to moderate collagenous stroma and moderate anisokariose and high mitotic activity were noted. The immunohistochemical assay showed positive staining for GFAP, S-100 protein and vimentin, and negative staining for factor VIII, α-actin and citokeratine. The definitive diagnosis of malignant peripheral nerve sheath tumor was made on the basis of the histological and immunohistochemical findings.
