Background: Road running is a growing sport. Objectives: To determine the prevalence of sports-related dermatoses among road runners. Methods: Cross-sectional study of 76 road runners. Assessment was performed by means of a questionnaire, interview, and clinical examination. The chi-square and linear trend tests were used for analysis. Results: Most athletes were men (61%), aged 38±11 years, who ran mid- or long-distance courses (60.5%) for 45 to 60 minutes (79%), for a total of 25-64 km (42.1%) or more than 65 km (18.4%) per week. The most prevalent injuries were blisters (50%), chafing (42.1%), calluses (34.2%), onychomadesis (31.5%), tinea pedis (18.4%), ony-chocryptosis (14.5%), and cheilitis simplex (14.5%). Among athletes running >64 km weekly, several conditions were significantly more frequent: calluses (p<0.04), jogger's nipple (p<0.004), cheilitis simplex (p<0.05), and tinea pedis (p<0.004). There was a significant association between the weekly running distance and the probability of skin lesions. Of the athletes in our sample, 57% trained before 10 a.m., 86% wore clothing and accessories for sun protection, 62% wore sunscreen, and 19.7% experienced sunburn. Traumatic and environmental dermatoses are common in practitioners of this outdoor sport, and are influenced by the weekly running distance. Conclusion: In this group of athletes, rashes, blisters, sunburn, and nail disorders were recurrent complaints regardless of running distance. Calluses, athlete's foot, chapped lips, and jogger's nipple predominated in individuals who ran longer routes. © 2014 by Anais Brasileiros de Dermatologia.

Genetics has been revolutionised by recent technologies. The latest addition to these advances is next-generation sequencing, which is set to transform clinical diagnostics in every branch of medicine. In the research arena this has already been instrumental in identifying hundreds of novel genetic syndromes, making a molecular diagnosis possible for the first time in numerous refractory cases. However, the pace of change has left many clinicians bewildered by new terminology and the implications of next-generation sequencing for their clinical practice. The rapid developments have also left many diagnostic laboratories struggling to implement these new technologies with limited resources. This review explains the basic concepts of next-generation sequencing, gives examples of its role in clinically applied research and examines the challenges of its introduction into clinical practice.

This study aims to describe the construction of knowledge as a component of professional power in gerontological nursing in Brazil between 1970 and 1996. It is a descriptive study with qualitative socio-historical approach that used oral history and was developed with 14 nurses, who are pioneers in the area. The categories found are: 1. The origin of gerontological nursing studies; 2. The inclusion of gerontology in the professional education; 3. The relevance of knowledge to the specialty. Historical understanding allowed to learn the efforts engaged for the development of scientific production in the area, by detailing the creation of research groups and the difficulties found in the professional education. The connection between knowledge and professional power is a unanimous discourse among the pioneer nurses, confirmed in the efforts made by them for the development of expertise in the area.

The procedure for obtaining the particle size distribution by visual inspection of a sample involves stereological errors, given the cut of the sample. A cut particle, supposedly spherical, with radius R, will be counted as a circular particle with radius r, r≤R. The difference between r and R depends on how far from the center of the sphere the cut was performed. This introduces errors when the extrapolation of the properties from two to three dimensions during the analysis of a sample. The usual method is to correct the distribution by probabilistic functions, which have large errors. This paper presents a method to reduce the error inherent to this problem. The method is to compute a simulation of the preparation process in a sample whose structure can be described by nonpenetrating spheres of various diameters which meet a known probability distribution function, for example, a log-logistic function, or even a constant function. For each distribution radius, a number of spheres is generated and virtually cut, generating a bi-dimensional (2D) distribution. The 2D curves of the spheres distribution obtained in this simulation are compared with that obtained by the experimental procedure and then the parameters of the threedimensional distribution function are adjusted until the 2D curves are similar to the experimental one using the optimization method Simulated Annealing for the curve-fitting. In future this method will be applied to the analysis of the oil reservoir rocks. © 2016 The authors and IOS Press.

BACKGROUND: In Curitiba, systemic hypertension (SH) is the second leading cause of hospitalization and the leading cause of death from cardiovascular diseases. The protocols for the treatment of hypertension provide a systematic approach to patient management, aiming at improving the efficiency and quality of health services. OBJECTIVE: To evaluate medical professionals' compliance with the protocol of hypertension of the Municipal Health Department (MHD) of the city of Curitiba. METHODS: This was a cross-sectional observational study. The data collection for the study was conducted in four health units in Curitiba. The sample consisted of 200 hypertensive patients enrolled in the hypertension program. The collected data refers to the first two consultations. The data source was the electronic records of the health units. The protocol used for comparative analysis was the protocol of the Municipal Health Department of Curitiba. RESULTS: The non-conformity percentage between clinical practice and the protocol in the first consultation was 56.8% on hypertension grade classification, 63.8% on cardiovascular risk evaluation, and 54% on treatment. In the second consultation, the non-conformity percentage was 67% on risk evaluation, and 51.3% on treatment. CONCLUSION: The non-conformity between clinical practice and the protocol of the MHD of Curitiba was evident on hypertension grade classification, cardiovascular risk evaluation, and treatment of hypertensive patients. This non-conformity may result in low efficiency of the health service, which hinders the efforts to reduce morbidity and mortality from cardiovascular disease in the population.

This article describe a rare case of multiple taurodontism involving all molars in a 17-year-old male. Volumetric cone-beam computed tomography was used to investigate internal and external root morphology, including that of a maxillary first molar which required endodontic treatment and retreatment. Medical history was not contributory; however, Klinefelter syndrome was the diagnostic hypothesis in this case.

The purpose of this article is to report the use of the subepithelial connective tissue graft technique combined with the coronally positioned flap on a composite resin-restored root surface to treat Miller Class I gingival recessions associated with deep cervical abrasions in maxillary central incisors. Clinical measurements, including gingival recession height, probing depth, and bleeding on probing (BoP), were recorded during the preoperative clinical examination and at 2, 6, 12, and 24 months postoperatively. During the follow-up periods, no periodontal pockets or BoP were observed. The periodontal tissue of the teeth presented normal color, texture, and contouring. In addition, it was observed that creeping attachment had occurred on the restoration. This case report shows that this form of treatment can be highly effective and predictable in resolving gingival recession associated with a deep cervical abrasion.

The treatment of furcation defects is a complex and difficult task that may compromise the success of periodontal therapy. Here we report a new clinical treatment of a Class II furcation defect using an autogenous bone graft associated with a buccal fat pad (BFP) used as a membrane. The surgical treatment was performed following initial periodontal therapy. Post-operative follow-up appointments were performed at 3, 7, and 12 months. Clinically, after 3 and 7 months, a reduction in probing depth without bleeding on probing and an increase in vertical and horizontal clinical attachment level were observed. After 7 post-operative months, an increase in keratinized gingiva was observed. Radiographically, a significant improvement was noted, with the furcation defect almost completely closed. These results could also be observed after 12 postoperative months. It can be concluded that the combined use of autogenous bone graft and a BFP yielded clinically favorable outcome in the treatment of a mandibular Class II furcation defect.

The success of endodontic therapy is based on good endodontic access, correct cleaning and shaping, and adequate root canal obturation. However, endodontic treatment is also dependent on a sound knowledge of the internal anatomy of human teeth, especially when anatomical variations are present. Certain anatomical changes may be present to varying degrees, and it is important to report these to improve the understanding and expertise of endodontic specialists. With this aim in mind, this study reports an example of a maxillary first molar showing unusual anatomy (four roots and six root canals) and describes the endodontic treatment that was employed.

The aim of this study was to evaluate the performance of undergraduates in their first contact with manual and rotary root canal instrumentation. Forty-two students who had never worked on a root canal before instrumented 42 extracted lower-incisors. Participants were assigned to one of two groups: Rotary instrumentation or manual instrumentation. Pre- and post-operative computed tomography scans were obtained with a 3-dimensional dental imaging system. Starting and finishing times of preparation were recorded. The cross-sectional area of the root canal was analyzed with 2-mm-below-the-apex initial and final transverse images recorded through a digital imaging system and analyzed with software to measure the initial and final area of the root canal in mm(2). Data from the cross-sectional area of the root canal and time spent were subjected to the Mann-Whitney's U-test (p<0.05). The rotary instrumentation group showed smaller time for preparation (p=0.0204). No differences between rotary and manual instrumentation regarding the cross-sectional area of the root canal were observed (p=0.25). No accidents occurred. Undergraduate students showed good performance in their first contact with the manual and rotary instrumentation with regard to time spent and cross-sectional area of the root canal, with no operative accidents.
