Trauma dos canalículos lacrimais

Purpose: To evaluate the canalicular trauma causes and the characteristics of the patients in our region. Local: Faculdade de Medicina de Botucatu - UNESP - Botucatu, São Paulo. Method: A retrospective observational study was conducted in a 7 years period evaluating 25 canalicular trauma carriers according gender, occupation, cause and lesion localization, associated structures affected, time to surgical procedure, surgery performed and results with the treatment. Results and conclusion: 68,0% of the patients were male and there is no age prevalence. The car accidents was the most important cause of canalicular trauma. The inferior canaliculus were the most frequently affected. The majority of the patients showed another structure lesioned (eye, eyelid or orbit) and most of patients presented good results with treatment.

Physical inactivity and related barriers: A study in a community dwelling of older brazilians

This study sought to investigate the prevalence of physical inactivity and related barriers in older Brazilian adults. A cross-sectional, population-based study was conducted, and a stratified random sampling procedure was used. A total of 359 older adults were interviewed. The long version of the International Physical Activity Questionnaire (IPAQ) and the Questionnaire of Barriers to Physical Activity Practice were used to assess physical activity level and barriers, respectively. No statistically significant difference was observed on the prevalence of physical inactivity in either gender or age groups. Regarding barriers, the proportion of 9 out of 22 barriers was statistically significant between men and women. Self-reported physical inactivity/activity in older Brazilian adults continues to be a concern. Uncommonly, older males reported a higher prevalence of physical inactivity compared to their counterparts. Additionally, physical inactivity prevalence continued to increase with the aging process. Yet, personal barriers such as lack of time and poor health were strongly associated with physical inactivity. The results of this study may help health professionals and public policy makers to better address the issues related to a healthy lifestyle among older adults and promote physical activity among Brazilian older adults and in other countries with similar characteristics. © 2012 Sebastião Gobbi et al.

Breaking down barriers:teenage girls’ perceptions of engineering as a study and career choice

Background: Stereotypically perceived to be an ‘all male’ occupation, engineering has for many years failed to attract high numbers of young women [1,2]. The reasons for this are varied, but tend to focus on misconceptions of the profession as being more suitable for men. In seeking to investigate this issue a participatory research approach was adopted [3] in which two 17 year-old female high school students interviewed twenty high school girls. Questions focused on the girls’ perceptions of engineering as a study and career choice. The findings were recorded and analysed using qualitative techniques. The study identified three distinctive ‘influences’ as being pivotal to girls’ perceptions of engineering; pedagogical; social; and, familial. Pedagogical Influences: Pedagogical influences tended to focus on science and maths. In discussing science, the majority of the girls identified biology and chemistry as more ‘realistic’ whilst physics was perceived to more suitable for boys. The personality of the teacher, and how a particular subject is taught, proved to be important influences shaping opinions. Social Influences: Societal influences were reflected in the girls’ career choice with the majority considering medical or social science related careers. Although all of the girls believed engineering to be ‘male dominated’, none believed that a woman should not be engineer. Familial Influences: Parental influence was identified as key to career and study choice; only two of the girls had discussed engineering with their parents of which only one was being actively encouraged to pursue a career in engineering. Discussion: The study found that one of the most significant barriers to engineering is a lack of awareness. Engineering did not register in the girls’ lives, it was not taught in school, and only one had met a female engineer. Building on the study findings, the discussion considers how engineering could be made more attractive to young women. Whilst misconceptions about what an engineer is need to be addressed, other more fundamental pedagogical barriers, such as the need to make physics more attractive to girls and the need to develop the curriculum so as to meet the learning needs of 21st Century students are discussed. By drawing attention to the issues around gender and the barriers to engineering, this paper contributes to current debates in this area – in doing so it provides food for thought about policy and practice in engineering and engineering education.

Empowering, degrading or a 'mutually exploitative' exchange For women?: Characterising the power relations of the strip club

This paper seeks to characterise the gendered and sexualised power relations of both female and male strip clubs, and to signal what this means for establishing positive definitions of female desire. It is argued that while it is not useful to present female strippers, or female patrons of male strip clubs as purely passive victims of male heterosexism within these venues, it is equally damaging to assume that these venues represent a whole-scale challenge to conventional oppressive gender and sexual relations for women. Some research has even suggested that both strippers and their patrons are engaged in a 'mutually exploitative' power relationship. Moreover, further empirical research documents key points where female dancers have perhaps wielded 'more' power over patrons at certain moments, and female dancers have highlighted feelings of empowerment and highlighted potential for gender and sexual relations which position women as passive to be subverted within stripping. However, such feelings are often temporally specific and are not applicable to all women in the strip industry. It may be particularly hard for these to manifest in women concentrated in the least economically-rewarding areas of the industry who have less 'power' to resist compromising their bodily boundaries. Furthermore, it is argued that women watching male strippers does little to reverse the 'male gaze', and nor does this male occupation carry as much negative social stigma with it as female stripping suffers. It is thus argued that the overwhelming picture, stemming largely from accounts of former dancers and from empirical studies of individual clubs, suggests these venues in fact do very little to challenge normative hetero-oppressive sexual scripts.

Männlichkeiten. Geschlechterkonstruktionen in pädagogischen Institutionen

Männlichkeiten stehen im Brennpunkt aktueller bildungspolitischer und erziehungswissenschaftlicher Debatten. Betrachtet man die Diskussion um Jungen als 'Bildungsverlierer', birgt bereits Männlichkeit als solche ein Benachteiligungsrisiko. Gleichzeitig gibt es Bestrebungen, dagegen anzugehen: Initiativen für mehr männliche Fachkräfte in Kindertagesstätten oder Schulen wollen durch die bloße Präsenz von Männern mehr Bildungsgerechtigkeit schaffen. Der vorliegende Band nimmt diese und andere Auffassungen von Männlichkeit kritisch in den Blick. Der Band kritisiert essentialisierende Thematisierungen von Männlichkeiten; eine unveränderliche, da, wahre' bzw. , natürliche' Sicht auf Männlichkeit hält sich nicht nur in pädagogischer Praxis und Bildungspolitik, sondern auch in Empirie und Theorie. Oftmals werden hier verkürzte Konzepte von Männlichkeit zu Grunde gelegt. Insbesondere die Verknüpfung von Männlichkeiten in pädagogischen Institutionen mit politischen Fragen von Bildung und sozialer Ungleichheit ruft Diskussionen um Geschlechterdifferenzen auf den Plan. Pädagogische Institutionen sind von besonderer Relevanz, da sie Einfluss auf (beispielsweise legitime und illegitime) Konstruktionen von Männlichkeiten nehmen. Gleichzeitig beeinflussen Männlichkeitskonstruktionen selbst die pädagogischen Institutionen. Die Autorinnen stellen sich der Herausforderung, Geschlecht theoretisch (neu) zu konzipieren und empirisch zum Gegenstand zu machen. Sie eröffnen damit neue Perspektiven auf Männlichkeit als solche.

Teaching boys in neoliberal and postfeminist times: Feminization and the question of re-masculinization in the education system and policy field

This paper focuses on teaching boys, male teachers and the question of gendered pedagogies in neoliberal and postfeminist times of the proliferation of new forms of capitalism, multi-mediated technologies and the influence of globalization. It illustrates how a politics of re-masculinization and its reconstitution needs to be understood as set against changing economic and social conditions in which gender equity comes to be re-focused on boys as the ‚new disadvantaged‘. This re-framing of gender equity, it is argued, has been fuelled by both a media-inspired backlash discourse about ‚failing boys‘ and a neo-positivist emphasis on numbers derived primarily from standardized testing regimes at both global and national levels. A media-focused analysis of the proliferation of discourses about ‚failing boys‘ vis-a-vis the problem of encroaching feminization in the school system is provided to illuminate how certain truths about the influence of male teachers come to define how the terms of ensuring gender equity are delimited and reduced to a question of gendered pedagogies as grounded in sexed bodies. Historical accounts of the feminization of teaching in the North American context are also provided as a basis for building a more informed understanding of the present, particularly as it relates to the contextualization of policy articulation and enactment regarding the problem of teaching boys. In light of such historically informed and critical media analysis, it is argued that what is needed is a more informed, evidenced based policy articulation of the problem of teaching boys and a more gender sensitive reflection on the politics of masculinities in postfeminist times.

Occupation, hours worked, and leisure-time physical activity

Background. International research indicates that blue-collar employees typically exhibit lower rates of leisure-time physical activity. While lack of time and work demands are commonly reported barriers to activity, the extent to which time-at-work mediates the relationship between occupation and leisure-time physical activity is unclear. This study investigated the association between occupation, time spent in paid employment, and participation in leisure-time physical activity. Methods. This was a secondary analysis of cross-sectional data from the 1995 Australian Health Survey, focusing on employed persons ages 18-64 years (n = 24,454), Occupation was coded as per the Australian Standard Classification of Occupations and collapsed into three categories (professional, white-collar, blue-collar). Hours worked was categorized into eight levels, ranging from 1-14 to more than 50 h per week. Participation in leisure-time physical activity was categorized as either insufficient or sufficient for health, consistent with recommended levels of energy expenditure (1600 METS-min/fortnight). The relationship between occupation, hours worked, and leisure-time physical activity was examined using logistic regression. Analyses were conducted separately for male and female, and the results are presented as a series of models that successively adjust for a range of potential covariates: age, living arrangement, smoking status, body mass index, and self-reported health. Results. Individuals in blue-collar occupations were approximately 50% more likely to be classified as insufficiently active. This occupational variability in leisure-time physical activity was not explained by hours worked. There was a suggested relationship between hours worked and leisure-time physical activity; however, this differed between men and women, and was difficult to interpret. Conclusions. Occupational variability in leisure-time physical activity cannot be explained by hours worked. Therefore, reports that work constitutes a barrier to participation should be explored further. Identification of the factors contributing to occupational variability in leisure-time physical activity will add to our understanding of why population subgroups differ in their health risk profiles, and assist in the development of health promotion strategies to reduce rates of sedentariness and health inequalities.

Activité professionnelle des utilisateurs d'implant cochléaire [Professional occupation after cochlear implantation]

This study verifies whether cochlear implants helps deaf adults to maintain or develop their professional occupations. Sixty-seven patients received a questionnaire concerning their professional activities before and after implantation. At the time of implantation 34 were professionally active. After the implantation 29 remained active, 4 of them reporting positive developments in their careers. Five patients became inactive. The previously inactive patients remained inactive. There was no difference in auditory performances between professionally active or inactive patients. Cochlear implants enable most implanted adults to maintain and even progress in their professions. However, deafness still represents an obstacle to social integration as inactive patients who searched for a job were rejected after the job interviews.

Exposure To Bisphenol-a During Pregnancy Partially Mimics The Effects Of A High-fat Diet Altering Glucose Homeostasis And Gene Expression In Adult Male Mice.

Bisphenol-A (BPA) is one of the most widespread EDCs used as a base compound in the manufacture of polycarbonate plastics. The aim of our research has been to study how the exposure to BPA during pregnancy affects weight, glucose homeostasis, pancreatic β-cell function and gene expression in the major peripheral organs that control energy flux: white adipose tissue (WAT), the liver and skeletal muscle, in male offspring 17 and 28 weeks old. Pregnant mice were treated with a subcutaneous injection of 10 µg/kg/day of BPA or a vehicle from day 9 to 16 of pregnancy. One month old offspring were divided into four different groups: vehicle treated mice that ate a normal chow diet (Control group); BPA treated mice that also ate a normal chow diet (BPA); vehicle treated animals that had a high fat diet (HFD) and BPA treated animals that were fed HFD (HFD-BPA). The BPA group started to gain weight at 18 weeks old and caught up to the HFD group before week 28. The BPA group as well as the HFD and HFD-BPA ones presented fasting hyperglycemia, glucose intolerance and high levels of non-esterified fatty acids (NEFA) in plasma compared with the Control one. Glucose stimulated insulin release was disrupted, particularly in the HFD-BPA group. In WAT, the mRNA expression of the genes involved in fatty acid metabolism, Srebpc1, Pparα and Cpt1β was decreased by BPA to the same extent as with the HFD treatment. BPA treatment upregulated Pparγ and Prkaa1 genes in the liver; yet it diminished the expression of Cd36. Hepatic triglyceride levels were increased in all groups compared to control. In conclusion, male offspring from BPA-treated mothers presented symptoms of diabesity. This term refers to a form of diabetes which typically develops in later life and is associated with obesity.

Indole-3-carbinol Attenuates The Deleterious Gestational Effects Of Bisphenol A Exposure On The Prostate Gland Of Male F1 Rats.

Bisphenol A (BPA) is a chemical that has been investigated for it potential to cause prostate diseases. In this study, pregnant Sprague-Dawley rats were treated with 25 or 250 μg/kg BPA from gestational day (GD) 10 to GD21 with or without concurrent indole-3-carbinol (I3C) feeding. I3C is a phytochemical, and it affords chemoprotection against many types of neoplasia. Male F1 rats from different litters were euthanized on post-natal day (PND) 21 and PND180. BPA-treated groups showed a significant increase in histopathological lesions, but I3C feeding reversed many of these changes, mainly at PND180. Maternal I3C feeding increased prostate epithelial apoptosis in the BPA-treated groups and across age groups. Furthermore, I3C induced partial normalization of the prostate histoarchitecture. The results pointed to a protective effect of maternal I3C feeding during pregnancy in the BPA-exposed male offspring, thereby indicating reduction in the harmful effects of gestational BPA imprinting on the prostate.

Gonadal Hormones Modulate The Responsiveness To Local β-blocker-induced Antinociception In The Temporomandibular Joint Of Male And Female Rats.

We have previously demonstrated that blockade of β-adrenoreceptors (β-AR) located in the temporomandibular joint (TMJ) of rats suppresses formalin-induced TMJ nociceptive behaviour in both male and female rats, but female rats are more responsive. In this study, we investigated whether gonadal hormones modulate the responsiveness to local β-blocker-induced antinociception in the TMJ of rats. Co-administration of each of the selective β1 (atenolol), β2 (ICI 118.551) and β3 (SR59230A)-AR antagonists with equi-nociceptive concentrations of formalin in the TMJ of intact, gonadectomized and hormone-treated gonadectomized male and female rats. Atenolol, ICI 118.551 and SR59230A significantly reduced formalin-induced TMJ nociception in a dose response fashion in all groups tested. However, a lower dose of each β-AR antagonist was sufficient to significantly reduce nociceptive responses in gonadectomized but not in intact and testosterone-treated gonadectomized male rats. In the female groups, a lower dose of β1 -AR antagonist was sufficient to significantly reduce nociceptive responses in gonadectomized but not in intact or gonadectomized rats treated with progesterone or a high dose of oestradiol; a lower dose of β2 -AR antagonist was sufficient to significantly reduce nociceptive responses in gonadectomized but not in intact and gonadectomized rats treated with low or high dose of oestradiol. Gonadal hormones may reduce the responsiveness to local β-blocker-induced antinociception in the TMJ of male and female rats. However, their effect depends upon their plasma level, the subtype of β-AR and the dose of β-blockers used.

Interictal hyposexuality in male patients with epilepsy

The purpose of this study was to compare the serum levels of androgens between hyposexual and non-hyposexual patients with epilepsy. Adult male patients with epilepsy were investigated. Serum levels of testosterone (T) and free-T, estradiol, and sex hormone binding globulin (SHBG) were measured and the free androgen index (FAI) was calculated. While there were no differences between hyposexual and non-hyposexual patients in the serum levels of T, free-T, and estradiol, or to the FAI, the serum levels of SHBG were significantly higher in hyposexual patients than in non-hyposexual patients. Thus, the effects of increased SHBG upon serum levels of testosterone biologically active in patients with epilepsy and hyposexuality were not detected by the methods used in this study. Four (44%) of nine hyposexual patients who were re-evaluated after two years follow-up improved sexual performance. Thus, clinical treatment that results in good seizure control may improve sexual performance in some patients with epilepsy.

46,XX Male - Testicular Disorder of Sexual Differentiation (DSD): hormonal, molecular and cytogenetic studies

The XX male syndrome - Testicular Disorder of Sexual Differentiation (DSD) is a rare condition characterized by a spectrum of clinical presentations, ranging from ambiguous to normal male genitalia. We report hormonal, molecular and cytogenetic evaluations of a boy presenting with this syndrome. Examination of the genitalia at age of 16 months, showed: penis of 3.5 cm, proximal hypospadia and scrotal testes. Pelvic ultrasound did not demonstrate Mullerian duct structures. Karyotype was 46,XX. Gonadotrophin stimulation test yielded insufficient testosterone production. Gonadal biopsy showed seminiferous tubules without evidence of Leydig cells. Molecular studies revealed that SRY and TSPY genes and also DYZ3 sequences were absent. In addition, the lack of deletions or duplications of SOX9, NR5A1, WNT4 and NROB1 regions was verified. The infant was heterozygous for all microsatellites at the 9p region, including DMRT1 gene, investigated. Only 10% of the patients are SRY-negative and usually they have ambiguous genitalia, as the aforementioned patient. The incomplete masculinization suggests gain of function mutation in one or more genes downstream to SRY gene.
