M. Epifanio, Matteo Baldisserotto, Valéria Sgnaolin
Open Journal of Radiology (OJRad) , 2013, DOI: 10.4236/ojrad.2013.34035
Abstract:

Purpose: To disseminate the current knowledge about the intestinal inflammatory processes in children and its approach by ultrasound (US) and provide necessary information to pediatricians for early diagnosis through this complementary method. Source of Data: The sources of data were selected by Medline, the international manuscripts, international medical journals more relevant in the last 20 years about Gray Scale and Color Doppler Ultrasound in the evaluation of inflammatory bowel disease in children and adolescents. Conclusions: Several authors have suggested that the ultrasound should be the first study in the diagnostic investigation process in suspected inflammatory bowel disease to determine the most affected region and monitor the therapy response. While colonoscopy still remains as the reference diagnostic method, the literature suggests that US can be an extremely useful tool in the context of the suspected diagnosis of a wide variety of intestinal inflammatory processes in children.

Abstract: For all infants we carried out physical assessment, photographic records, analysis of medical records and collection of additional information with the family, besides the karyotypic analysis or molecular tests in indicated cases.The incidence of birth defects was 2.8%. Among them, the etiology was identified in 73.6% (ci95%: 64.4-81.6%). Etiology involving the participation of genetic factors single or associated with environmental factors) was more frequent 94.5%, ci95%: 88.5-98.0%) than those caused exclusively by environmental factors (alcohol in and gestational diabetes mellitus). The conclusive or presumed diagnosis was possible in 85% of the cases. Among them, the isolated congenital heart disease (9.5%) and Down syndrome (9.5%) were the most common, followed by gastroschisis (8.4%), neural tube defects (7.4%) and clubfoot (5.3%). Maternal age, parental consanguinity, exposure to teratogenic agents and family susceptibility were some of the identified risk factors. The most common observed consequences were prolonged hospital stays and death.The current incidence of birth defects among newborns and stillbirths of in our population is similar to those obtained by other studies performed in Brazil and in other underdeveloped countries. Birth defects are one of the major causes leading to lost years of potential life. The study of birth defects in underdeveloped countries should continue. The identification of incidence, risk factors and consequences are essential for planning preventive measures and effective treatments.Birth defects (BD) or congenital anomalies include all structural and functional alterations in embryonic or fetal development resulting from genetic, environmental or unknown causes, which result in physical and/or mental impairment. There may be single or multiple alterations with major or minor clinical significance [1,2]. The incidence of BD is 3 to 5% among newborn babies [3]. BD comprise a complex and heterogeneous group of embryonic and/o

Abstract: this study compared the mandibular displacement from three methods of centric relation record using an anterior jig associated with (a) chin point guidance, (b) swallowing (control group) and (c) bimanual manipulation. ten patients aged 25-39 years were selected if they met the following inclusion criteria: complete dentition (up to the second molars), angle class i and absence of signs and symptoms of temporomandibular disorders and diagnostic casts showing stability in the maximum intercuspation (mi) position. impressions of maxillary and mandibular arches were made with an irreversible hydrocolloid impression material. master casts of each patient were obtained, mounted on a microscope table in mi as a reference position and 5 records of each method were made per patient. the mandibular casts were then repositioned with records interposed and new measurements were obtained. the difference between the two readings allowed measuring the displacement of the mandible in the anteroposterior and lateral axes. data were analyzed statistically by anova and tukey's test at 5% significance level. there was no statistically significant differences (p>0.05) among the three methods for measuring lateral displacement (a=0.38 ± 0.26, b=0.32 ± 0.25 and c=0.32 ± 0.23). for the anteroposterior displacement (a=2.76 ± 1.43, b=2.46 ± 1.48 and c=2.97 ± 1.51), the swallowing method (b) differed significantly from the others (p<0.05), but no significant difference (p>0.05) was found between chin point guidance (a) and bimanual manipulation (c). in conclusion, the swallowing method produced smaller mandibular posterior displacement than the other methods.

Abstract: the goal of this study was to evaluate the effect of using die spacers on the marginal fit of nicr (m1) and nicrbe (m2) alloys and commercially pure titanium (cpti) (m3) copings cast by the lost wax technique. using a metal matrix, 45 resin added extra hard type iv stone models were obtained for the fabrication of wax patterns under the following conditions: no die spacer (a), with one die spacer layer (b) and with two die spacer layers (c), with five repetitions for each condition (alloy x die). each die was waxed and the wax patterns were invested as per manufacturer's instructions. three wax patterns were embedded in each casting ring, each corresponding to one of the conditions. each coping, seated to the metal matrix by a seating pressure standardizing device (spsd), was taken to an optical microscope for measurement of marginal discrepancy. the obtained data (μm) were analyzed statistically by anova and tukey' test (a=5%). there was statistically significant difference (p<0.05) among the materials (m1=110.67; m2=130.33 and m3=148.33). regarding the use of the die spacer, there was a statistically significant difference (p<0.05) among the three conditions (a=162.00; b=131.06 and c=96.67). it was concluded that there is less marginal discrepancy with two die spacer layers.

Abstract: the success of metal-ceramic restorations depends on an optimal bond between metal and ceramic. this study evaluated the effect of 3 casting atmospheres on the metal-ceramic bond strength (mcbs) of 2 ni-cr alloys, with beryllium (fit cast v) and without beryllium (fit cast sb). sixty acrylic resin patterns (8 mm long and 5 mm diameter) were obtained using a fluorocarbon resin matrix. wax was used to refine the surface of acrylic resin patterns that were invested and cast in an induction casting machine under normal, vacuum, and argon atmospheres at a temperature of 1340oc. the castings were divested manually and airborne-particle abraded with 100-μm aluminum-oxide. ten castings were obtained for each group. the ips classic v ceramic was applied (2 mm high and 5 mm diameter). the shear bond strength was tested in a mechanical testing machine with a crosshead speed of 2.0 mm/min. the mcbs data (mpa) were subjected to 2-way analysis of variance (α=0.05). there was no statistically significant difference (p>0.05) between the alloys or among the casting atmospheres. within the limitations of this study, it may be concluded that the presence of beryllium and the casting atmosphere did not interfere in the mcbs of the evaluated metal-ceramic combinations
