Small predators tend to eat small prey, whereas larger predators attack predominantly larger prey. Neotropical primates form a substantial proportion of the total food resource available to predators, but their interactions are poorly addressed. We investigated through a review of the literature whether the body mass of predators predicts primate body mass. The mean size of predator species explained 53% of the variation in the size of the primates. Large felids, especially the jaguar, concentrate their efforts on large primates. Body size is a fundamental underlying factor in the evolution of trophic relations between Neotropical primates and their predators. Predadores de pequeno porte tendem a consumir presas pequenas, enquanto predadores maiores atacam predominantemente presas maiores. Os primatas neotropicais formam uma proporção relevante do volume total de recurso alimentar disponível para os predadores, mas as interações entre eles são pouco estudadas. Nós investigamos, através de revisão da literatura, se a massa corporal dos predadores determina a massa corporal dos primatas. O peso médio das espécies de predadores explicou 53% da variação no tamanho dos primatas. Felinos de grande porte, especialmente a onça, concentram seus esforços em primatas de maior porte. O tamanho do corpo é um fator fundamental e determinante na evolução das relações tróficas entre os primatas neotropicais e seus predadores. © 2013 Copyright Taylor and Francis Group, LLC.

The Sun Protection Factor (SPF) is the most important data to quantify the effectiveness of a sunscreen, being universally accepted. The method is based on determining the minimum erythematous dose (MED), defined as the smallest amount of energy required for triggering the erythema, in areas of protected and unprotected skin. The SPF value is then calculated as the ratio between the MED of protected and unprotected skin. The first publication of a method for determining the SPF was presented in 1978 by the U.S. FDA agency, followed by other publications of FDA and other international regulatory agencies. Although considered the reference method for quantification of sunscreen efficacy of topical products, there are controversies in literature about the method for determining the SPF and the implications of the real conditions of use in the protection achieved in practice by users. © 2011 by Anais Brasileiros de Dermatologia.

PURPOSE: To analyze the risk factors associated with obesity and overweight in school children of both sex. METHOD: Survey study carried out with 162 children students from a public school in the city of São Paulo, SP, Brazil. Data collection was obtained by means of a form with anthropometric data and about dietary habits. Data were analyzed using inferential statistics. RESULTS: Obese and over weighted children represent 38.2% of the sample. Relevant associated risk factor was the use of soda beverages and the practice of physical exercises. CONCLUSION: The study highlighted the presence of obesity and overweight in the sample under study, confirming the global trend of change in the nutritional profile of the population in general.

This study aimed to verify with the community of Tenentes District (Extrema Municipality, Minas Gerais State, Brazil) how diseases are treated by using medicinal plants, as well as to identify and relate the used plants to the scientific literature. Thus, interviews were done and plants used in the local folk medicine were collected; after the herborization process and identification, the obtained data were compared with information available in the literature. Seventy-one species were identified; they belonged to 33 botanical families, of which Asteraceae and Lamiaceae were most expressive. Leaves and branches (88%) were the most used part and the most frequent form of preparation was infusion (67%). The plants were indicated especially for the treatment of illness associated with digestive (23 species), respiratory (16), excretory (10), nervous (6), circulatory (5), endocrine (4) and woman reproductive systems (2), as healing (7), anti-inflammatory (4), and for general body aches (5).

This was a retrospective study, which aimed to describe the profile of nursing diagnoses of 31 patients starting hemodialysis treatment in a hemodialysis clinic in the South Zone of São Paulo. The survey was conducted from patients' records. The data used included: patient identification, underlying disease, data from physical examination notes and multidisciplinary evaluations. The most prevalent nursing diagnoses included: ineffective renal tissue perfusion (100.0%), risk for infection (100.0%), innefective protection (80.6%) and ineffective management of therapeutic regimen (54.8%). It was concluded that the identification of the profile of nursing diagnoses of these patients is essential for the planning of nursing care after initiation of hemodialysis.

Although relatively rare, the gastrointestinal stromal tumors comprise most mesenchymal tumors of the digestive tract and account for 5% of all sarcomas. The most common symptoms are pain, gastrointestinal bleeding and palpable mass. This study reported the case of a young patient who developed hemoperitoneum due to gastric neoplasm rupture and required urgent surgical treatment. Pathology and immunohistochemistry analysis showed an epidemiologically rare case: epithelioid and c-KIT negative tumor.

Non-iatrogenic traumatic cervical esophageal perforations are usually hard to manage in the clinical setting, and often require a careful and individualized approach. The low incidence of this particular problem leads to a restricted clinical experience among most centers and justify the lack of a standardized surgical approach. Conservative treatment of esophageal perforation remains a controversial topic, although early and sporadic reports have registered the efficacy of non-operative care, especially following perforation in patients that do not sustain any other kind of injuries, and who are hemodynamically stable and non-septic. We report a case of a patient sustaining a single cervical gunshot wound compromising the cervical esophagus and who was treated exclusively with cervical drainage, enteral support and antibiotics.

Background: Psoriasis exerts a significant negative effect on quality of life and is associated with comor-bidities. The inflammatory activity of the psoriasis plaques is partially triggered by activation of the Th1 lymphocytes, which release proinflammatory cytokines such as TNF-alpha. Infliximab neutralizes the biological activity of TNF-alpha. Adverse reactions that occur during infusion or up to 24 hours afterwards are referred to as acute reactions. Delayed reactions are those occurring between 24 hours and 14 days after an infusion. Objective: To evaluate the profile of patients with moderate to severe psoriasis that is resistant to conventional treatment, and to assess adverse reactions to infliximab. Methods: Fifty-three patients, 40 men and 13 women, were treated with infliximab. The dose used was 5 mg/kg in weeks 0, 2 and 6 (induction phase), followed by maintenance therapy every 8 weeks. Results: Of the 53 patients, 6 participated only in the induction phase. These patients reached Psoriasis Area Severity Index (PASI) of 90-100 and opted to discontinue treatment. Forty-seven patients continued therapy with the drug for at least 2-3 years. Of these, 55.3% (n=26) experienced some type of adverse event. Acute adverse events were recorded in 34% of the patients and delayed adverse events in 36.1%. The prevalence of comorbidities was 57.4%. Conclusion: In the present study, infliximab was found to constitute a safe and effective form of therapy. Of the comorbidities recorded in the patients in this study, obesity was associated with a delayed and less effective response to treatment. When adequately monitored, neither acute nor delayed adverse events require discontinuation of therapy, since they do not represent an uncontrolled risk to the patient. © 2011 by Anais Brasileiros de Dermatologia.

Because of the advances made with the industrial revolution through technological discoveries in machinery, professional-patient relationship has become increasingly automated, leaving the humanization in the background. The purpose of this paper was to reflect about the humanization process in intensive environments and its relation with the technology insertion. Technology contributes as an effective way to treat patients who require extreme care. However, if it is associated with humanization can achieves satisfactory results, improving the host of customer who receives the care provided by technology.

The Special Public Health Service (Serviço Especial de Saúde Pública) reframed both the training and the professional identity of Brazilian nursing when it reopened the doors to black men and women. This is the premise of the present article, which uses the historical method to analyze the results of Brazil's Nursing Program based on the personal experience of one of its actors. Primary sources consist of the documents attached to the academic dossier of Maria de Lourdes Almeida, one of the first beneficiaries of a grant from the Service and head nurse with the Araraquara Special Health Service, part of the Center for Training School of Hygiene and Public Health at the Universidade de São Paulo. It is argued that the Nursing Program, which was implemented in Brazil under the Estado Novo, changed the professional profile of Brazilian nursing after the 1930s and solidified the interventionist policy promoted in the Vargas era.
