title: Influence of cortical thickness on the stability of mini-implants with microthreads

description: The objective of this study was to assess the influence of cortical thickness and bone density on the insertion torque of a mini-implant (MI) with microthreads. Mini-implants with lengths of 6 and 8 mm in the active part were inserted into synthetic bone blocks (polyurethane resin). The density of these blocks was 20 pounds per cubic foot (pcf), simulating bone marrow, and that of blocks 1, 2, and 3-mm-thick blocks was 40 pcf, simulating cortical bone. Blocks with uniform density of 40 pcf were also used to simulate bone areas of greater density. Insertion torque was quantified with a universal testing machine (EMIC). For both MIs, increasing insertion torque was associated with increasing cortical bone thickness. For the same MI length, significant differences were observed among all assessed groups. The insertion torque of the 6-mm-long MI inserted in a 3-mm-thick cortical bone was equivalent to that of the 8-mm-long MI inserted in a 1-mm-thick cortical bone. MIs inserted in bone blocks of greater density presented insertion torque values almost twice as high as those in other groups. The shorter MI, the lower the insertion torque, and the greater the cortical bone thickness, the greater the insertion torque. To minimize fracture risk, the size of MI should be selected according to the insertion site.

title: Assessment of skeletal and dental ages of children and adolescents with type 1 Diabetes Mellitus

description: The present study aimed to assess the skeletal and dental ages of type 1 diabetes mellitus (T1DM) patients. Therefore, panoramic and hand-wrist radiographs of 82 patients, aged between 5 and 15 years, were collected and divided into case and control groups. The case group consisted of 41 panoramic and 41 hand-wrist radiographs of T1DM patients, whereas the control group consisted of 41 panoramic and 41 hand-wrist radiographs of patients without T1DM. Skeletal age was assessed according to the method of Greulich and Pyle (1999), whereas dental age was assessed according to the method of Nolla (1960). Chi-square tests revealed no statistically significant differences between skeletal and dental ages between the case and control groups (p &gt; 0.05). However, in the case group, the skeletal age of females was greater than that of age-matched males (p = 0.005). Considering that skeletal and dental growth of the case and control groups were closely related, clinical interventions involving orthodontics and dentomaxillofacial orthopedics should be equally performed both for healthy and specific patient groups, such as those with T1DM.

title: Epidemiological and imaging features that can affect the detection of ureterolithiasis on ultrasound

description: Abstract Objective: To identify, in patients with clinical suspicion of ureterolithiasis, epidemiological and imaging features that affect calculus detection on ultrasound, as well as to compare ultrasound with multidetector computed tomography (MDCT). Materials and Methods: We searched our database for patients who underwent ultrasound, followed by MDCT (if the ultrasound was negative), for suspected ureterolithiasis in an emergency setting. Patients were divided into three groups: positive ultrasound (US+); negative ultrasound/positive MDCT (US−/MDCT+); and negative ultrasound/negative MDCT (US−/MDCT−). We evaluated age, gender, ureterolithiasis laterality, location of the calculus within the ureter, body mass index, calculus diameter, and calculus attenuation on MDCT. Results: Of a total of 292 cases of suspected ureterolithiasis, 155 (53.1%) were in the US+ group, 46 (15.7%) were in the US−/MDCT+ group, and 91 (31.2%) were in the US−/MDCT− group. There were no significant differences among the groups in terms of age, gender, ureterolithiasis laterality, and mean MDCT attenuation values. Distal ureterolithiasis was most common in the US+ group, and calculi at other ureteral locations were more common in the US−/MDCT+ group. The mean body mass index was significantly higher in the US−/MDCT+ group than in the US+ group, and the mean calculus diameter was significantly greater in the US+ group than in the US−/MDCT+ group. Conclusion: A high body mass index, large calculus diameter, and calculus location in the distal third of the ureter are the major factors favoring ureterolithiasis detection on ultrasound.

title: Family burden among caregivers of people with mental disorders: an analysis of health services

description: Abstract The objective of this study was to analyze the objective and subjective levels of burden felt by family caregivers of patients who were treated at three institutions: a General Psychosocial Care Center (known as ‘CAPS Geral’), a CAPS center for Alcohol and Drugs (‘CAPS AD’) and the Psychiatric Admissions Unit of a General Hospital (‘UIPHG’) in the municipality of Sobral, Ceara State, Brazil. The study included 385 caregivers, 216 of whom were in the CAPS Geral, 86 in the CAPS AD and 83 in the UPHG, and applied the Family Burden Interview Scale (FBIS-BR). Excel and SPSS were used to organize and analyze the data, and a 5% significance level was applied. The results show that the general objective burden was greater for caregivers at the UIPHG. This group was also found to bear a greater objective burden with regard to caring in day-to-day life. The analysis of the subjective sub-scales showed that caregivers from the UIPHG group were most troubled by supervising problematic behaviors and also by the future and patient’s type of care and medical treatment. Variables including sex and age were associated with burden.

title: Negative binomial distribution and multiplicities in proton collisions

description: Abstract Particle production in proton collision experiments provides fundamental information on the mechanisms of initial energy conversion of protons in a number of secondary particles by measuring their Multiplicity Distribution in strong nuclear interactions. In this context, the Negative Binomial Model has been extensively used in theoretical studies and parameterization of experimental information, making it important to know the hypotheses involved in the elaboration of the model, in order to provide adequate application and interpretation of results. We thus conduct a discussion of the Negative Binomial Model based on the realization of a classic random experiment, which leads and assists in obtaining the analytical expression of the Probability Function. We also express the said Function of Probability in terms of the Gamma Function, the multiplicity variable and the average multiplicity adopting a mathematical procedure not found in the specific literature. Implications of the application of the model in the study of Multiplicities Distributions in collisions between protons are discussed.

title: Aqua regia as an alternative extractor for the environmental diagnosis of areas impacted by industrial waste: case study Centres (Queimados, RJ)

description: ABSTRACT Metal contaminated areas lead to environmental and public health risks. In the 1980s, dangerous industrial waste storage was initiated in the CENTRES area in the municipality of Queimados, Rio de Janeiro, Brazil. The inadequate management of these wastes has promoted a large environmental impact to this region’s soils. The Brazilian legislation for diagnostics of contaminated areas limits the extraction of metals on soils to USEPA 3050-B and USEPA 3051-A methods. However, many researchers use the aqua regia method for extracting metals in soil, but there are few studies comparing concentrations of metals extracted by aqua regia and USEPA 3051A. Therefore, the objective of this work was to evaluate if the method of extracting metals in soils by aqua regia is statistically different from US EPA 3051A. The results showed that the Cd, Cr, Cu, Ni, Pb and Zn concentrations using both extractions were statistically similar. It was also observed that Cu, Ni, Pb and Zn concentrations were higher than the industrial investigation value which characterizes this area as highly contaminated and soil class 4.

title: Frozen Section in the Management of Ovarian and Uterine Tumors: The Past 5 Years in a Tertiary Centre

description: Abstract Objective Intraoperative frozen section (IFS) is a valuable resource, and its use in gynecological pathology has not been sufficiently emphasized. The main goal of the present study is to evaluate the reliability and agreement rates between IFS and the final paraffin section (PS) and determine how reliable IFS is. Methods A retrospective study of all IFSs performed on uterine tumors and suspicious adnexal masses between January 2012 and December 2016 (excluding metastases) at the department of obstetrics and gynecology of the Centro Hospitalar Tondela Viseu. Frozen versus permanent section diagnosis were compared regarding the histologic type of the tumor, and the depth of myometrial invasion. Results A total of 286 cases were eligible for the present study, including 102 (35.7%) IFSs of uterine tumors, and 184 (64.3%) IFSs of ovarian tumors. The overall rate of deferred cases was 5.2% (15/286). The accuracy of the diagnosis in cases of endometrial carcinoma was 96.25% (77/80). Among the ovarian tumors, misdiagnoses occurred in 2 cases (1.1%), corresponding to a borderline tumor (serous type) and a clear cell intracystic adenocarcinoma. Conclusion The IFS analysis plays an important role in selected situations and is associated to a high sensitivity and specificity in cases of ovarian and endometrial tumors. Its high accuracy is almost universally associated with the possibility of obtaining an optimal surgical treatment at the time of the first surgical approach.

title: Mineral content of ionomer cements and preventive effect of these cements against white spot lesions around restorations

description: This study evaluated the ion exchange at the material/enamel interface and the preventive effect of restorative materials submitted to cariogenic challenge against white spot. Restorations in enamel/dentin of bovine teeth were performed with composite resin (Filtek™ Z250 – control group) and glass-ionomers cements - GICs (Ionomaster R™ and Fuji IX™ - experimental groups). Samples were grouped and submitted to neutral saliva (n = 15) or pH-cycling regimen (n = 15). After eight days of pH cycling, material/enamel interfaces were analyzed by EDX in order to determine the differences (p &lt; 0.05) in ionic exchange (Ca, P, F, Al, Sr, and Si) between restorative materials and teeth. In addition, enamel white spot lesion formation was evaluated macroscopically (p &lt; 0.05). Sr content was higher in the enamel of the control group (p &gt; 0.05) versus the experimental groups. Ca and P content were higher in enamel than in restorative materials. After pH cycling, the GIC enamel bulk showed a significantly higher Sr content compared with the composite resin (p &lt; 0.05). Filtek™ Z250 was not able to prevent white spot formation around restorations in comparison with Ionomaster R™ (p &lt; 0.001) and Fuji IX™ (p = 0.004). GICs reduced white spot formation and presented a preventive effect (p = 0.051). GICs presented a greater percentage of fluoride, aluminum, and strontium, and proved effective in white spot lesion prevention around restorations.
