This paper aims to apply a model of water quality, the Sistema de Apoio a Decisao/Instituto de Pesquisas Hidraulicas (SAD-IPH), in the Piracicaba River basin. The quality parameters were modeled biochemical oxygen demand (BOD), dissolved oxygen (DO), total phosphorus, nitrogen and thermotolerant coliforms. The flow data were obtained through the application of the hydrological model Modelo de Grandes Bacias/IPH (MGB-IPH). The quality model was calibrated using data from stations monitoring the water quality of the Instituto Mineiro de Gestao das Águas (IGAM). The curves of Bod, DO and total phosphorus showed good adherence to data from monitoring campaigns. The parameters organic nitrogen, ammonia, nitrite, nitrate, and coliforms were underestimated by the model. Most streams have the quality of its waters compatible with Class 4. Current concentrations are well above what would be ideal for the basin, as its current framework is in Class 2. © 2017, ABES - Associacao Brasileira de Engenharia Sanitaria e Ambiental.

A study was carried out to describe users of methotrexate injectable solution, as well as to estimate proportion of inappropriate setting of administration and factors associated. Participants included had at least a prescription from January to July, 2010, in Specialized Component of Pharmaceutical Services in Health Region of Belo Horizonte, State of Minas Gerais, Brazil. This study was cross-sectional and retrospective. A total of 513 subjects were included in research. Administration in pharmacy, Unit of Basic Health Care and residence was considered inappropriate. Majority of individuals was female, aged 20 to 59 years-old and lived in municipalities with 500.000 habitants or more. Setting of administration of methotrexate was inappropriate in 93,6% patients. Residence in larger cities was associated with an inappropriate setting of administration (p‹0,05). Results of research can subsidize actions to promote appropriate administration of methotrexate and rational use of this medicine. © 2014, Colegio de Farmaceuticos de la Provincia de Buenos Aires.

Objective: To compare the accuracy of craniometric measurements made on lateral cephalograms and on cone beam computed tomography (CBCT) images. Materials and Methods: Ten fiducial markers were placed on known craniometric landmarks of 25 dry skulls with stable occlusions. CBCT scans and conventional lateral headfilms subsequently were taken of each skull. Direct craniometric measurements were compared with CBCT measurements and with cephalometric measurements using repeated measures analysis of variance (ANOVA). All measurements were repeated within a 1-month interval, and intraclass correlations were calculated. Results: No statistically significant difference was noted between CBCT measurements and direct craniometric measurements (mean difference, 0.1 mm). All cephalometric measurements were significantly different statistically from direct craniometric measurements (mean difference, 5 mm). Significant variations amongmeasurements were noted. Somemeasurements were larger on the lateral cephalogram and some were smaller, but a pattern could be observed: midsagittal measurements were enlarged uniformly, and Co-Gn was changed only slightly; Co-A was always smaller. Conclusion: CBCT craniometric measurements are accurate to a subvoxel size and potentially can be used as a quantitative orthodontic diagnostic tool. Two-dimensional cephalometric norms cannot be readily used for three-dimensional measurements because of differences in measurement accuracy between the two exams. © 2011 Education and Research Foundation, Inc.

Well-placed dental implants are a prerequisite of functional and esthetically successful dental implant - supported crowns. The presence of soft tissue is essential for excellent esthetics because the dental implant or titanium abutment may become visible if the soft-tissue contour is not acceptable. This clinical report describes the use of a custom ceramic implant abutment designed with computer-aided design and computer-aided manufacturing (CAD/CAM) technology by milling a zirconia framework that was cemented extraorally to a prefabricated titanium abutment with a reduced diameter. This ceramic abutment has the strength and precise fit of a titanium interface and also the esthetic advantages of shaded custom-milled zirconia, with no visible metal.

Tumors of the pineal region are rare in adulthood, accounting for approximately 1% of intracranial neoplasms in this age range. Papillary tumor of the pineal region (PTPR) was first described by Jouvet et al. in 2003. In 2007, PTPR was included by the World Health Organization as a distinct entity in their new classification of central nervous system tumors. We report a case of PTPR, and undertake a literature review of this rare neuroepithelial neoplasm. Patients with PTPR need long-term follow up, and new cases should be well documented so that we can gain a better understanding of this neoplasm. © 2011 The Japan Society of Brain Tumor Pathology.

The lacrimal drainage system consists of the lacrimal puncta, inferior and superior canaliculi, common canaliculus, lacrimal sac, and nasolacrimal duct. It is classically divided into upper and lower portions. Obstruction of the drainage system can be congenital or acquired, and may result in persistent epiphora and mucopurulent discharge. This paper discusses the etiology, clinical picture, diagnosis, and surgical treatment of lacrimal drainage system obstruction. © 2010 Informa UK Ltd.

Ectropion is the most frequent eyelid malposition, characterized by the eversion of the margin and exposure of the conjunctiva and the cornea. It is classified as congenital (primary and secondary) and acquired (involutional, paralytic, mechanical and cicatricial). Congenital ectropion is rare and it is usually associated with other malformations such as euryblepharon, ptosis, epicanthus inversus, and blepharophimosis syndrome. Involutional ectropion is the most frequent form of acquired eyelid eversion and a result of multiple factors. The mechanisms involved in its pathogenesis are discussed in this review. Cicatricial ectropion is caused by the shortening of the anterior lamella of the lid, secondary to congenital malformations, trauma, burns, skin conditions, scarring skin tumors, medications, allergies, blepharoplasty complications, and involutional changes that result in loss of skin elasticity. Mechanical ectropion is caused by eyelid tumors or inflammatory disorders that cause orbicularis spasm. The evaluation of the patient, selection of treatment and surgical techniques are described in detail. © 2010 Informa UK Ltd.

Introduction The objectives of this study were to evaluate the prevalence and long-term behavior of extraction space reopening in patients with Class I malocclusion and to identify some associated factors. Methods A sample of 43 patients met the inclusion criteria. Dental casts at the onset of treatment, after treatment, and 1 and 5 years after debonding were used. Initial and final cephalometric radiographs were used to measure the amount of incisor retraction. Cochran tests were used to compare the numbers of open and closed extraction spaces after treatment and at 1 and 5 years after debonding (P <0.05). Initial incisor crowding, amounts of anterior retraction, and angulations between the canines and the second premolars were compared between patients with and without space reopening with t tests. Results Of the sample, 30.23% had extraction space reopening. The frequency of open spaces significantly increased between the final and the 1-year posttreatment dental casts and decreased between the casts at 1 and 5 years posttreatment. Patients with space reopening had less initial anterior crowding and greater amounts of mandibular incisor retraction during treatment. Conclusions There was a high prevalence of space reopening 1 year after treatment. However, these spaces tended to decrease by 5 years after treatment. © 2016 American Association of Orthodontists.

Introduction. Besides hypogonadism, other endocrine disorders have been associated with male sexual dysfunction (MSD). Aim. To review the role of the pituitary hormone prolactin (PRL), growth hormone (GH), thyroid hormones, and adrenal androgens in MSD. Methods. A systematic search of published evidence was performed using Medline (1969 to September 2011). Oxford Centre for Evidence-Based Medicine-Levels of Evidence (March 2009) was applied when possible. Main Outcome Measures. The most important evidence regarding the role played by PRL, GH, thyroid, and adrenal hormone was reviewed and discussed. Results. Only severe hyperprolactinemia (>35ng/mL or 735mU/L), often related to a pituitary tumor, has a negative impact on sexual function, impairing sexual desire, testosterone production, and, through the latter, erectile function due to a dual effect: mass effect and PRL-induced suppression on gonadotropin secretion. The latter is PRL-level dependent. Emerging evidence indicates that hyperthyroidism is associated with an increased risk of premature ejaculation and might also be associated with erectile dysfunction (ED), whereas hypothyroidism mainly affects sexual desire and impairs the ejaculatory reflex. However, the real incidence of thyroid dysfunction in subjects with sexual problems needs to be evaluated. Prevalence of ED and decreased libido increase in acromegalic patients; however, it is still a matter of debate whether GH excess (acromegaly) may create effects due to a direct overproduction of GH/insulin-like growth factor 1 or because of the pituitary mass effects on gonadotropic cells, resulting in hypogonadism. Finally, although dehydroepiandrosterone (DHEA) and its sulfate have been implicated in a broad range of biological derangements, controlled trials have shown that DHEA administration is not useful for improving male sexual function. Conclusions. While the association between hyperprolactinemia and hypoactive sexual desire is well defined, more studies are needed to completely understand the role of other hormones in regulating male sexual functioning. © 2012 International Society for Sexual Medicine.

Introduction. Endocrine disorders may adversely affect men's sexual function. Aim. To provide recommendations based on best evidence for diagnosis and treatment of endocrine-related male sexual dysfunctions. Methods. The Endocrine Aspects of Male Sexual Dysfunctions Committee, including 11 members from eight countries and four continents, collaborated with the Endocrine subcommittee of the Standards Committee of the International Society for Sexual Medicine. Medical literature was reviewed in detail, followed by extensive internal committee discussion over 2 years, then public presentation and discussion with the other experts before finalizing the report. Main Outcome Measure. Recommendations based on grading of evidence-base medical literature and interactive discussion. Results. From animal studies, it is derived that testosterone modulates mechanisms involved in erectile machinery, including expression of enzymes that both initiate and terminate erection. In addition, testosterone is essential for sexual motivation. Whether these findings could be extrapolated to human erections is unclear. Testosterone plays a broad role in men's overall health. Recent studies have established strong associations between low testosterone and metabolic and cardiovascular imbalances. In some studies, low testosterone decreased longevity; however, longitudinal studies do not support the predictive value of low testosterone for further cardiovascular events. The article proposes a standardized process for diagnosis and treatment of endocrine-related male sexual dysfunctions, updating the knowledge on testosterone and prostate safety. There is no compelling evidence that testosterone treatment causes prostate cancer or its progression in men without severe testosterone deficiency (TD). The possible roles of prolactin and thyroid hormones are also examined. Conclusions. Men with erectile dysfunction, hypoactive sexual desire and retarded ejaculation, as well as those with visceral obesity and metabolic diseases, should be screened for TD and treated. Prospective interventional studies are required before screening for TD in more conditions, including cardiovascular diseases, and considering correction as preventive medicine as much data suggests.
