title: Experiment and learning in the affective and sexual life of young women from a favela in Rio de Janeiro, Brazil, with experience of clandestine abortion

description: Abstract This paper discusses the topic of first sexual intercourse in adolescence focusing on the course of ten young girls with experience of induced abortion living in a favela in Rio de Janeiro. The analysis uses the description of the process of entry into sexuality as a strategy to elucidate the context of pregnancy and the first clandestine abortion in the affective-sexual path of girls interviewed. The first sexual intercourse is a realm of sexuality and social life involving socialization, interpretation of rules and meanings, system of attitudes, ways of approximation, control and modeling of affections, emotions and gender relationships. The results showed that the age difference between couples in sexual initiation is significant, clarifying the context in which decisions on contraceptive methods, pregnancy and abortion were held. We noted that adolescents subject to difficult decisions about their sexuality and reproduction at a time of life where they still lack sexual and reproductive experience. The data collected show the importance of strengthening of public policies, discussions on gender and adolescent sexual and reproductive rights in many spheres of society, such as schools, family and other institutions.

title: Young population, sexually-transmitted diseases and rights. National and regional scenario in Argentina

description: Abstract In the context of social and demographic studies of sexual and reproductive health, this paper discusses the situation of young people in Argentina, emphasizing the problems revolving around Sexually Transmitted Diseases (STDs) and the compliance with sexual rights. This work aims to study the calendars and characteristics of the onset of sexual life in young Argentinean people and to describe the current situation of knowledge, practices, and access related to sexual life. Based on data from the National Survey on Sexual and Reproductive Health ( 2013) we worked with the universe of young people between 15 and 29 years of age (n = 2,084 women, n = 1,872 men, without weighting) and analyzed the differences in the calendars of the onset of sexual life, as well as the knowledge and prevention of STDs by gender sex, age groups, household income and geographical regions.A national scenario was found featuring marked tendencies in the calendars of first sexual intercourse by gender sex, as well as in the knowledge about STDs. However, the analysis by region and household income in each gendersex showed high heterogeneities, which would indicate certain limitations in the access to sexual education and the effective compliance of people’s rights, as well as an increased risk to contracting STDs in specific social groups.

title: Dental age estimation in a Brazilian adult population using Cameriere’s method

description: The objectives of this study were to develop a specific formula to estimate age in a Brazilian adult population and to compare the original formula from Cameriere to this Brazilian formula. The sample comprised 1,772 periapical radiographs from 443 subjects (219 men, 224 women) that were organized into 12 groups according to sex (men or women) and age (20-29, 30-39, 40-49, 50-59, 60-69, and 70 years and older). The films were analyzed using the criteria described by Cameriere et al. (2004) and Adobe Photoshop®. We obtained a mean error of 8.56 (SD = 5.80) years for tooth 13, 7.99 (SD = 5.78) years for tooth 23, 8.38 (SD = 6.26) years for tooth 33, and 8.20 (SD = 6.54) years for tooth 43. When teeth were combined in the analysis, we observed lower mean errors. The Brazilian formula developed from this sample group was more accurate than Cameriere’s formula. However, other factors must be considered to improve age estimates in adults.

title: Knowledge and behavior of dentists in a dental school regarding toothbrush disinfection

description: The aim of this study was to evaluate the knowledge and behavior of dentists regarding toothbrush disinfection. This study included 147 dentists (88 women and 59 men) who were actively employed at a dental school in Ankara, Turkey. Participants were asked to fill out a standard questionnaire, which contained questions regarding their demographics, brushing habits, toothbrush storage and disinfection habits, toothpaste use, knowledge about toothbrush disinfection, and whether they advised their patients about toothbrush storage. Descriptive statistics were calculated, and statistical analyses were performed with t-tests, chi-squared tests, and Fisher exact tests, where appropriate. Among the 147 surveyed dentists, 62.6% and 85.7% reported that they did not have any knowledge about toothbrush disinfection and did not disinfect their toothbrushes, respectively. However, approximately two thirds of surveyed dentists thought that toothbrush disinfection should be performed by everyone, including healthy individuals. Significant associations were found between knowledge about toothbrush disinfection and the professional title of dentists, how they stored their toothbrushes, and whether their toothbrushes were in contact with each other during storage (p &lt; 0.05). A minority of dentists reported that they disinfected their toothbrushes.

title: Laparoscopic treatment of celiac axis compression by the median arcuate ligament and endovascular repair of a pancreaticoduodenal artery aneurysm: case report

description: Abstract Compression of the celiac axis by the median arcuate ligament of the diaphragm can cause nonspecific symptoms such as abdominal pain, vomiting, and weight loss. There is a known association between stenosis or occlusion of the celiac trunk and aneurysms of the pancreaticoduodenal artery. Treatment strategies for patients who have this association should be selected on a case-by-case basis. We describe the case of a patient with pancreaticoduodenal artery aneurysm associated with compression of the celiac trunk by the arcuate ligament, which were managed with endovascular and laparoscopic techniques, respectively.

title: Dentin hypersensitivity treatment of non-carious cervical lesions – a single-blind, split-mouth study

description: This study aims to compare the in vivo effect of a desensitizing therapy associated with a restorative technique for the treatment of cervical dentin hypersensitivity (CDH) in non-carious lesions. The sample consisted of 68 teeth with moderate or severe dentin hypersensitivity in 17 individuals (one tooth per quadrant). The sensitivity levels of the teeth were scored, and the teeth were randomly distributed into four groups: T1 – desensitizing gel applied once per week until remission of pain; T2 – desensitizing gel applied once per week followed immediately by restoration with resin composite (Filtek Z250, 3M Espe); T3 – desensitizing gel once per week until remission of pain and then restoration with resin composite; and T4 - restoration with resin composite. Dentin hypersensitivity was assessed at 0, 7, 30, 90 and 180 days. The Kruskal-Wallis, Wilcoxon and Mann-Whitney (p&lt; 0.05) tests were used to compare the treatments. The mean baseline CDH scores were T1 - 2.41, T2 - 2.41, T3 - 2.47, and T4 - 2.70 (p &gt; 0.05). At seven and 180 days, the mean CDH scores were as follows: T1 - 1.47/0.65, T2 - 1.35/0.71, T3 - 0.71/0.53, and T4 - 1.12/0.59, all of which were significantly lower (p&lt; 0.001) than the baseline scores. The scores at 30, 90 and 180 days were not significantly different when compared to the score of the previous period. At 180 days, CDH scores were similar among groups (p&gt; 0.05). Teeth with moderate or severe hypersensitivity that required a filling responded similarly regardless of whether the desensitizing procedure was carried out prior to the filling.

title: Impact of autologous whole blood administration upon experimental mouse models of acute Trypanosoma cruzi infection

description: Abstract Background: Autologous whole blood (AWB) administration is described as alternative/complementary medical practice widely employed in medical and veterinary therapy against infections, chronic pathologies and neoplasias. Our aim is to investigate in vivo biological effect of AWB using healthy murine models under the course of Trypanosoma cruzi acute infection. Methods: The first set of studies consisted of injecting different volumes of AWB and saline (SAL) into the posterior region of quadriceps muscle of healthy male Swiss mice under distinct therapeutic schemes evaluating: animal behavior, body and organ weight, hemogram, plasmatic biochemical markers for tissue damage and inflammatory cytokine levels and profile. To assess the impact on the experimental T. cruzi infection, different schemes (prior and post infection) and periods of AWB administration (from one up to 10 days) were conducted, also employing heterologous whole blood (HWB) and evaluating plasma cytokine profile. Results: No major adverse events were observed in healthy AWB-treated mice, except gait impairment in animals that received three doses of 20 μL AWB in the same hind limb. AWB and SAL triggered an immediate polymorphonuclear response followed by mononuclear infiltrate. Although SAL triggered an inflammatory response, the kinetics and intensity of the histological profile and humoral mediator levels were different from AWB, the latter occurring earlier and more intensely with concomitant elevation of plasma IL-6. Inflammatory peak response of SAL, mainly composed of mononuclear cells with IL-10, was increased at 24 h. According to the mouse model of acute T. cruzi infection, only minor decreases (&lt; 30%) in the parasitemia levels were produced by AWB and HWB given before and after infection, without protecting against mortality. Rises in IFN-gamma, TNF-alpha and IL-6 were detected at 9 dpi in all infected animals as compared to uninfected mice but only Bz displayed a statistically significant diminution (p= 0.02) in TNF-alpha levels than infected and untreated mice. Conclusions: This study revealed that the use of autologous whole blood (AWB) in the acute model employed was unable to reduce the parasitic load of infected mice, providing only a minor decrease in parasitemia levels (up to 30%) but without protecting against animal mortality. Further in vivo studies will be necessary to elucidate the effective impact of this procedure.

title: Saliva, supragingival biofilm and root canals can harbor gene associated with resistance to lactamic agents

description: This study aimed to determine the presence of Prevotella strains and genes associated with resistance to lactamics in different oral niches from patients with/without primary endodontic infections. Saliva (S) and supragingival biofilm (SB) were collected from three patient groups: Group I – no endodontic infection (n = 15); Group II – acute endodontic infection (n = 12); and Group III – chronic endodontic infection (n = 15). Root canal (RC) samples were collected from Groups II and III. The presence of P. intermedia, P nigrescens, P. tannerae and cfxA/cfxA2 gene was assessed by PCR. The cfxA/cfxA2 gene was not detected in all environments within the same patient. The cfxA/cfxA2 gene was present in 23.81% of S samples, 28.57% of SB samples, and 7.41% of RC samples. Prevotella species were detected in 53.97%, 47.62% and 34.56% of the S, SB, and RC samples, respectively. P. intermedia had a high frequency in saliva samples from Group 3. Saliva samples from Group 1 had higher detection rates of P. nigrescens than did Groups 2 and 3. Patients without endodontic disease had high frequencies of P. nigrescens in the SB samples. The presence or absence of spontaneous symptoms was not related to the detection rates for resistance genes in the RC samples. Saliva, supragingival biofilm and root canals can harbor resistant bacteria. The presence of symptomatology did not increase the presence of the cfxA/cfxA2 gene in the supragingival biofilm and inside root canals.
