A series of studies was conducted to compare group differences in the goal orientations of delinquent, at-risk, and not-at-risk adolescents. An Importance of Goals Scale was developed by examining the item responses of 230 high school students and validated by administering the revised scale to 80 delinquent, 90 at-risk, and 90 not-at-risk adolescents. Results identified differences in the importance attributed to different goals by the 3 groups. Delinquent and at-risk adolescents attached significantly more importance to goals associated with developing a social image (e.g., delinquency, freedom-autonomy), whereas not-at-risk adolescents were more concerned with goals associated with an academic image (e.g., educational, interpersonal). Results are discussed in terms of their implications for school achievement, peer relations, and future life paths.

On 20 December 1996, Justice J Finn of the Federal Court of Australia handed down his judgment in the case of the Tobacco Institute of Australia (TIA) Ltd and others v the National Health and Medical Research Council (NHMRC) and others. Justice Finn concluded that, in developing its recommendations for control of environmental tobacco smoke, the NHMRC's Working Party on Passive Smoking erred significantly in regard to the consultative procedures that it employed. As the following discussion shows, the legal decision has profound implications for the NHMRC and the provision of expert advice to Australian governments on matters of health and health policy. The discussion has been prepared by three members of the NHMRC Working Party, but reflects their personal views and not necessarily those of the Working Party as a whole or those of the NHMRC.

Clinical trial is considered a breakthrough method in medicine and essential to the development of new drugs. Clinical trials that comply with international and national regulations require an appropriate infrastructure and team qualification. The goal of this study was to evaluate clinical trial groups in Brazil: professional qualification, site structure regulatory knowledge and Good Clinical Practice (GCP) adherence. This is a transversal study with investigators (PI) and sub investigator (SI). PI and SI data were initially identified from Curriculum Lattes from National Advice of Scientific and Technological Development. The study participants were submitted to a questionnaire, which was composed of qualitative and quantitative questions. A hundred PI and SI were interviewed. The most representative Brazilian regions were Southeast (68%) and South (18%). The main institutions involved were HCFMUSP complex and UNIFESP among others institutions. Academic graduation is observed in 86% of them and the higher degree is Doctorate (62%). 91% had GCP knowledge although only 74% had formal training. About the team, all of them are multidisciplinary with majority of nurses and pharmaceuticals. 88% had GCP knowledge although only 77% had formal training. 36%, 60% and 44% of clinical trials were in phase II,III and IV. In conclusion, researchers have appropriate skills and knowledge to perform clinical studies however there is still a need for training. The centers where the researchers work, have trained staff and adequate infrastructure for conducting clinical trials phase II,III and IV. (C) 2010 Elsevier Inc. All rights reserved.

Background. Physical inactivity is recognized as an important public health issue. Yet little is known about doctors' knowledge, attitude, skills, and resources specifically relating to the promotion of physical activity. Our survey assessed the current practice, perceived desirable practice, confidence, and barriers related to the promotion of physical activity in family practice, Methods. A questionnaire was developed and distributed to all 1,228 family practitioners in Perth, Western Australia. Results. We received a 71% response (n = 789). Family practitioners are most likely to recommend walking to sedentary adults to improve fitness and they are aware of the major barriers to patients participating in physical activity. Doctors are less confident at providing specific advice on exercise and may require further skills, knowledge, and experience, Although they promote exercise to patients through verbal advice in the consultation, few use written materials or referral systems, Conclusions. There are significant differences between self-reports of current practice and perceived desirable practice in the promotion of physical activity by doctors, Future strategies need to address the self-efficacy of family physicians and involve resources of proven effectiveness. The potential of referral systems for supporting efforts to increase physical activity by Australians should be explored. (C) 1997 Academic Press.

Dengue has emerged as a frequent problem in international travelers. The risk depends on destination, duration, and season of travel. However, data to quantify the true risk for travelers to acquire dengue are lacking. We used mathematical models to estimate the risk of nonimmune persons to acquire dengue when traveling to Singapore. From the force of infection, we calculated the risk of dengue dependent on duration of stay and season of arrival. Our data highlight that the risk for nonimmune travelers to acquire dengue in Singapore is substantial but varies greatly with seasons and epidemic cycles. For instance, for a traveler who stays in Singapore for 1 week during the high dengue season in 2005, the risk of acquiring dengue was 0.17%, but it was only 0.00423% during the low season in a nonepidemic year such as 2002. Risk estimates based on mathematical modeling will help the travel medicine provider give better evidence-based advice for travelers to dengue endemic countries.

To determine whether peer-reviewed consensus statements have changed clinical practice, we surveyed acromegaly care in specialist centers across the globe, and determined the degree of adherence to published consensus guidelines on acromegaly management. Sixty-five acromegaly experts who participated in the 7th Acromegaly Consensus Workshop in March 2009 responded. Results indicated that the most common referring sources for acromegaly patients were other endocrinologists (in 26% of centers), neurosurgeons (25%) and primary care physicians (21%). In sixty-nine percent of patients, biochemical diagnoses were made by evaluating results of a combination of growth hormone (GH) nadir/basal GH and elevated insulin like growth factor-I (IGF-I) levels. In both Europe and the USA, neurosurgery was the treatment of choice for GH-secreting microadenomas and for macroadenomas with compromised visual function. The most widely used criteria for neurosurgical outcome assessment were combined measurements of IGF-I and GH levels after oral glucose tolerance test (OGTT) 3 months after surgery. Ninety-eight percent of respondents stated that primary treatment with somatostatin receptor ligands (SRLs) was indicated at least sometime during the management of acromegaly patients. In nearly all centers (96%), the use of pegvisomant monotherapy was restricted to patients who had failed to achieve biochemical control with SRL therapy. The observation that most centers followed consensus statement recommendations encourages the future utility of these workshops aimed to create uniform management standards for acromegaly.

Introduction. After hematopoietic stem cell transplantation (HSCT), many patients present genital graft-vs.-host disease (GVHD) that can culminate with sexual problems, which are poorly dimensioned. Aim. We hope to draw attention to the need to perform genital biopsy to diagnose genital GVHD, and thus to call attention to the need to incorporate careful attention to sexual health in the treatment of these patients. Methods. Five allogeneic stem cell transplant recipients complaining of coital pain after HSCT were clinically diagnosed for genital GVHD. Genital biopsies were given for histological analysis, and microphotographs of the corresponding marked field in the slide were taken. Specimens were evaluated by the site pathologist and then sent to a reference pathologist, each blinded to the histological findings. A literature search was performed in PubMed/MEDLINE (1966-2009) for cross-sectional and cohort studies or trials related to genital GVHD. Expert opinions peer reviews and case reports were also considered. Main Outcome Measures. HSCT, genital GVHD, genital biopsy. Results. The biopsy showed evidence of dilated apoptotic cells in the basal layer and detachment of the epithelial lining of the mucosa, hyalinization and thickening of collagen fibers, capillary ectasia, and mononuclear inflammatory infiltrate of the submucosa. Three patients presented vulval lesion such as leucoplasia and ulcer on the large lip. Histological analyses showed evidence of epithelial hyperplasia and influx of inflammatory cells to the epithelial surface, intercellular edema and spongiosis, apoptotic bodies on the basal layer of the epithelium, spongiosis, and nuclear vacuolization. A common treatment based on corticotherapy resulted in complete remission of coetaneous or mucous genital lesions in all five patients. Conclusion. Genital biopsy is important to differentially diagnose GVHD and secondary symptoms due to hypoestrogenism. Prevention is the most important step in controlling the evolution GVHD in the vagina to prevent vaginal obstruction and sexual dysfunction. da Silva Lara LA, de Andrade JM, Mauad LMQ, Ferrarese SR, Marana HRC, Tiezzi DG, and de Sa Rosa e Silva ACJ.

Low birth weight and preterm birth, and social disadvantage may negatively affect mental health of children, but findings have been inconsistent. To assess the influence of perinatal and social factors on mental health problems in children aged 7-9 years. A random sample of 805 births in So Luis, Brazil was studied in 1997/1998 and again in 2005/2006. Perinatal, socioeconomic and demographic variables were assessed within 24 h after delivery. The Strengths and Difficulties Questionnaire (SDQ) was used to assess mental health problems in the children. Simple and multiple Poisson regressions were used for statistical analysis. The overall prevalence of mental health problems in the total sample was 47.7%. The prevalences of emotional and conduct problems were 58.2 and 48.8%, respectively. Only paternal age (< 20 years) was associated with mental health problems as measured by the full SDQ scale (prevalence ratio PR = 1.27). Children born to single mothers (PR = 1.31) and those with birth weight from 1,500 to 2,499 g (PR = 1.18) and from 2,500 to 2,999 g (PR = 1.17) had a higher risk of emotional problems, but those from low income families had a lower risk (PR = 0.80). Children with a father of less than 20 years had a higher risk of having problems with their peers (PR = 1.75). A maternal education of 9 years or over was inversely associated with peer (PR = 0.70) and conduct problems (PR = 0.73). Girls had a lower risk of conduct (PR = 0.77) and hyperactivity problems (PR = 0.68). A maternal education of 4 years or less increased the risk of hyperactivity (PR = 1.48). Socioeconomic and demographic conditions were better predictors of mental health problems in children than birth weight or preterm birth. However, since most effect sizes were small most mental health problems were, unexplained by the variables in the study.

The key to successful long-term management of diabetes in cats is individualization of advice to suit cat and owner. A relationship based on trust and cooperation between veterinarian and client leads invariably to the most satisfactory outcome. Success requires knowledge of the options for monitoring diabetic cats, selection and adaptation of appropriate techniques for each individual case, and provision of ongoing support and guidance for owners. The ongoing treatment of a diabetic cat can be one of the more rewarding experiences of feline practice, and many diabetic cats and their owners come to occupy a special place within the clinic environment. This chapter provides a comprehensive overview of the current options for monitoring diabetes in cats and guidelines for application of the techniques to clinical cases.

Authorised trustee status is a legal concept which has economic implications; one of the major implications is that it assists in the direction of investment funds into particular securities and areas of the economy. The concept of authorised trustee status, while attempting to achieve specific outcomes for the beneficiaries of trusts cannot be relied upon to secure these results. Economic analysis of the role of the trustee maintains that this role is one of portfolio manager; a role which is complex but which is explicable in terms of definable procedures and practices. The role of trustee as portfolio manager is one which requires greater financial knowledge than can be assumed is possessed by all trustees. The trustee as portfolio manager is required to maintain a review of decisions make under powers to invest trust assets. A solution to the problem of authorised trustee status is proposed. The solution takes two parts: the first is the adoption of the prudent person approach but with the codification of duties of the trustee and the explicit listing of the factors that a trustee should consider in using the investment powers. The second part of the proposed solution is to link the investment powers of trustees to the best practice features of securities advisers who are now licensed by a regulatory body, the Australian Securities and Investment Commission.

After providing some background on the domestication and use of elephants in ancient India, this article concentrates on the role of the elephant in Indian statescraft as outlined in Kautilya’s Arthasastra, reputed to have been written in the fourth century BC (over 2300 years ago). The body of this essay is presented as follows: first background on the nature of Kautilya’s Arthasastra is provided and then his advice is outlined and discussed about the care of elephants. This care involves the duty of the King, the duties of the superintendent of elephants and the law relating to the treatment of elephants. Subsequently, Kautilya’s views about the use of elephants in war are considered. The essay concludes with an overall assessment of the role of the elephant in the polity of ancient India as portrayed by Kautilya. It is argued that the high use value of elephants to ancient Indian rulers, especially in war, had a significant positive impact on the conservation of Asian wild elephants, and incidentally other wildlife in India as well. Today, the conservation of the Asian elephant depends mostly on its use for tourism and its non-use economic values which reflect human empathy with it and which are reinforced in India by social and cultural values.

Introduction: The purpose of this study was to compare the occlusal stability of Class II malocclusion treatment with and without extraction of 2 maxillary premolars. Methods: A sample of 59 records from patients with complete Class II malocclusion was used. This sample was divided into 2 groups with the following characteristics: group 1, comprising 29 patients treated without extractions, and group 2, comprising 30 patients treated with extraction of 2 maxillary premolars. Dental cast measurements were obtained before and after treatment and at a minimum of 2.4 years after treatment. The pretreatment, posttreatment, and postretention occlusal statuses were evaluated with the peer assesment rating index. The occlusal indexes at the postretention stage and the posttreatment changes and percentages of posttreatment changes were compared with t tests. Results: The nonextraction and the 2 maxillary premolar extraction treatment protocols of complete Class II malocclusions had no statistically significant differences in occlusal stability. Conclusions: Finishing Class II malocclusion treatment with the molars in a Class II relationship has similar occlusal stability as finishing with the molars in a Class I relationship.

The objective of this study was to compare, on study models and initial cephalograms, the efficiency of Class II malocclusion treatment with the pendulum appliance, and with two maxillary premolar extraction protocol. The sample consisted of 48 treated Class II malocclusion patients: group 1 comprised 22 patients (7 males, 15 females) treated with the pendulum appliance, with an initial mean age of 14.44 years and group 2, 26 patients (14 males, 12 females) treated with two maxillary premolar extractions at an initial mean age of 13.66 years. To compare the efficiency of each treatment protocol, the occlusal outcomes were evaluated on dental casts using the Peer Assessment Rating (PAR) Index and the treatment time (TT) of each group was calculated on clinical charts. The degree of treatment efficiency was calculated as the ratio between the percentage of occlusal improvement, evaluated through the PAR index, and TT. Statistical analysis was undertaken by means of t-tests. The findings demonstrated that the two maxillary premolar extraction protocol provided the occlusal outcomes in a shorter time (group 1: 45.7 months, group 2: 23.01 months) and, therefore, demonstrated greater treatment efficiency than the pendulum appliance.
