Influência de calços na orientação postural de indivíduos com escoliose idiopática

INTRODUCTION: The relationship between the orientation of the segments and the adjustments that can be triggered by shoe lift and insoles in scoliotic patients during maintenance of standing position is unclear. OBJECTIVE: To verify static changes and those associated with unilateral manipulations of shoe lift in the postural orientation in people with idiopathic scoliosis. MATERIALS AND METHODS: Experimental group composed of ten patients with idiopathic scoliosis with double curve (less 10°) and control group with ten participants without scoliosis (aging from 13 to 24 years). Participants were videotaped in upright stance, standing with no, low (1 cm), and high (3 cm) shoe lift, which were placed under right and left shoe. In each condition, the participant maintain upright stance for 15 seconds and reflective markers were affixed on specific anatomical places. Postural angles were obtained: high thoracic; medium thoracic; thoracolumbar; and lumbar, as well segmental angles: shoulder; scapula; pelvis; and knee. RESULTS: In the no shoe lift condition, differences were observed between groups for high and medium thoracic angles and for shoulder. With low and high shoe lift under the right foot, difference was observed between shoe lift heights for high thoracic, for pelvis and knee angles. With low and high shoe lift under the left foot, differences between groups were observed for thoracolumbar angle and between shoe lift heights for pelvis and knee angles. CONCLUSIONS: The shoe lift promotes reorientation in the lower regions of the spine and segments of pelvis and knee. It might be suggested that in the scoliosis with double curves, manipulation in the basis of support changes the alignment of the trunk that might promote structural reorganization and the search of new adjustments among segments in individuals with idiopathic scoliosis.

Pelvic differences between brachycephalic and mesaticephalic cats and indirect pelvimetry assessment

Pelvic measurements were carried out in cats with various cranial conformations to (1) determine pelvic morphometry, (2) compare any pelvic differences with cranial conformation and gender and (3) determine whether body biometrics can be used to predict pelvic measurements. Thirteen brachycephalic and 14 mesaticephalic female cats and 17 brachycephalic and nine mesaticephalic male cats were used. Body and external pelvic measurements, as well as pelvic radiographs, were performed. Brachycephalic females all had external pelvic and radiographic measurements that were significantly smaller than those of the mesaticephalic females, including smaller pelvic inlet and outlet areas and a smaller pelvic canal shape. Brachycephalic females had wider and flatter heads than do mesaticephalic females. Similarly, brachycephalic males all have radiographic pelvic measurements that are smaller than those of mesaticephalic males. Males had larger pelvis measurements than did their female counterparts for both cranial types, and indirect pelvimetry did not demonstrate good predictive value in determining the internal pelvic measurements. Thus, we conclude that pelvic differences exist between genders and between brachycephalic and mesaticephalic cats. Furthermore, body biometric measurements do not have good predictive value for determining internal pelvic measurements.

Iliac osteosynthesis with nylon clamp associated to polymethylmethacrylate bone cement - experimental study in dogs cadavers

Fractures of iliac body are generally consequences of traumas of great impact. These fractures lead to a lack of locomotor response and in specific cases, surgery is needed. Among the possible therapeutic lines, implants become a good option. In this paper, the authors used dog corpses to develop a surgery technique of iliac osteosynthesis, employing nylon clamps and bone cement of polymethylmethacrylate (PMMA). Sixteen hemi pelvises of eight dog corpses, which had its iliac bodies totally fractured previously, were utilized. The osteosynthesis was reached through the implantation of six nylon clamps, distributed equally between the bone fragments. With the use of the nylon clamps there were bone realignment and a contact surface to fixation of the biomaterial. The technique developed in corpses was easily executed, effective in reduction, alignment and stabilization of the fracture. The authors suggest more studies in vitro to evaluate immobilization resistance and functionality in dogs with this condition.

Estudo da toxicidade de diferentes doses do Diuron (3-(3,4 -dichlorophenyl)-1,1-dimethylurea) no epitélio da bexiga de ratos wistas machos por microscopia eletrônica de varredura

Diuron (3-(3,4-Dichlorophenyl)-1,1-dimethylurea) is a substituted urea herbicide widely used on agricultural crops such as soy, cotton and sugar cane. In a previous long-term study this herbicide exerted carcinogenic activity on the urinary bladder and renal pelvis mucosa of Wistar rats and breast of mice. Also, it was shown to be carcinogenic to the mice skin in a initiation-promotion assay. In 1997, the northamerican EPA evaluated Diuron as a “known/likely” carcinogen for humans (USEPA, 2004). In a previous study developed at this laboratory, male Wistar rats treated with Diuron 2500 ppm during 20 weeks presented increased indices of cell proliferation and incidences of simple urothelial hyperplasia (HS) in the urinary bladder. Under scanning electron microscopy (SEM) severe urothelial necrosis and hyperplasia were observed. However, in that study the urinary bladders of animals exposed to lower doses of Diuron were not examined under SEM. Therefore, the possible dose-response influence of Diuron on the urothelium under SEM is not known. The present study aimed to analyze under SEM the urinary bladder of male Wistar rats exposed to 125 ppm, 500 ppm and 2500 ppm doses of Diuron through diet during 20 weeks and to compare to the previous histological findings in the same material. Under SEM, 125 ppm and 2500 ppm groups presented significantly (p<0,05) increased incidences of simple hyperplasia, i.e., 7/10 and 8/10 respectively, compared to control group and the 500 ppm group The sensitivity of SEM was higher since it detected a 45% incidence of hyperplasiaswhile the histological analysis found only 27%. Considering SEM as the gold-standard, histology showed a 44% sensitivity, 86.4% specificity, a positive predictive value of 72,7% and negative predictive value of 65,5% and accuracy of 67,5%.

Expressão do gene Glipican 3 (Gpc3) no urotélio da bexiga de ratos expostos ao diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea) por 7 dias e 20 semanas

Diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea) is a substituted urea herbicide widely used in crops of sugar cane, cotton and soybeans. In 1997, this agent has been classified by the United States Environmental Protection Agency as known/likely human carcinogen because it induced tumors in the urinary bladder and renal pelvis of rats, and breast and skin of mice exposed to 2500 ppm for feed for two years. A previous study from our group demonstrated dose-response relationship in the gene expression profile associated with severe necrosis on bladder urothelium and increased incidence of simple hyperplasia in male Wistar rats treated with different concentrations of diuron for 20 weeks. To check how early the molecular changes occurs, rats were fed for 7 days with diets containing diuron at 0, 125, 500 or 2500 ppm. The main observations recorded were urothelium ultrastructural alterations and disruptions of molecular pathways associated with cell-cell interaction and the tissue organization maintenance. Particularly, the gene Glypican 3 (Gpc3), a surface proteoglycan related to cellular adhesion and apoptosis induction, was down regulated on urothelium exposed to 2500ppm diuron for 7 days and 20 weeks. The aim of this study was validate by quantitative RT-PCR real time, the reduced Gpc3 gene expression in epithelial cells of the urinary bladder of male Wistar rats treated with different concentrations of diuron for 7 days and 20 weeks. The endogenous control of the quantitative PCR real time technique was the β-actin gene and the target was the gene Gpc3. The relative quantification (RQ) was obtained by the method of relative quantification 2-ΔΔCt . Animals exposed to diuron for 7 days or for 20 weeks presented reduction of Gpc3 gene expression compared to the control group. This reduction was statistically significant only for the 7 days study. Moreover, by comparing animals exposed for 7 days with the exposed for 20 weeks, it was ...

Análise da flexibilidade e da postura em jovens atletas praticantes de futebol

there is evidence that sport can trigger the onset of postural patterns specific to each modality, regardless of the geopolitical aspects, social, cultural habits of everyday life and ethnicity. Since changes in flexibility are cited as possible precursors of decreased range of motion, thereby harming the mechanics of the lower limbs and gait. Objetcive: The objective of this study was to analyze changes in posture and flexibility in young soccer players. Methods: were assessed 51 youngsters, aged between 14 and 18 years, soccer players registered in the Municipal Presidente Prudente SP and categories of the base of Gremio of Presidente Prudente. Data were collected from the assessment by the postural software assessment, and flexibility tests the Bench, to jail and later by tests of muscle length to jail earlier proposed by Kendall et al , was also collected anthropometric data were later confronted with the results statistically. The results were organized into spreadsheets for computing, which later could be performed the statistical analysis. Values are expressed by means of central tendency and variability as well as medians and 95% confidence intervals. The comparison for each profile height and BMI was made by means of analysis of variance complemented by Tukey test. Were considered the statistical differences when P <0.05. Results: In the sample studied 64% of the subjects classified as normal posture, the same happened with 70.59% of the athletes for flexibility in relation to the center of gravity of the sample had 100% anterior displacement of the trunk and 86.28% with a deviation of center of gravity to the left, showing a tendency to some postural deviations for the group assessed. Conclusion: from the results we can conclude that there was significant relationship between the postural angle of the right leg and left angle of the pelvis with BMI and also ankle angle...
