Dermatological diseases of compulsory notification in Brazil

A estruturação do Sistema Nacional de Vigilância Epidemiológica do Brasil, em 1975, tornou obrigatória a notificação de algumas doenças transmissíveis com o objetivo de reduzir a carga destes eventos no país. Entretanto, as alterações no perfil epidemiológico destas doenças, associadas a características da sociedade contemporânea, determinam a constante adequação das atividades de vigilância a este cenário. Neste manuscrito, são descritos epidemiologia, tendências e diagnóstico diferencial das seguintes doenças dermatológicas de notificação compulsória no Brasil: aids, dengue, hanseníase, leishmaniose tegumentar americana, sarampo, rubéola e síndrome da rubéola congênita e sífilis. Também são apresentados os principais desafios atuais para o controle e prevenção para cada uma dessas doenças no BrasilThe development of a Brazilian National Surveillance System in 1975 led to a compulsory reporting of selected infectious diseases aiming to reduce the burden of these events in the country. However, shifts in the epidemiology of these diseases associated with modern life style, demand constant revision of surveillance activities. In this manuscript we present the epidemiology, trends and differential diagnosis of the following compulsory notifiable diseases in Brazil: Aids, dengue fever, hanseniasis, American tegumentary leishmaniasis, measles, rubella and congenital rubella syndrome and syphilis. Additionally, the current challenges for control and prevention of each disease are presente

Prospective Observational Study on acute Appendicitis Worldwide (POSAW)

Acute appendicitis (AA) is the most common surgical disease, and appendectomy is the treatment of choice in the majority of cases. A correct diagnosis is key for decreasing the negative appendectomy rate. The management can become difficult in case of complicated appendicitis. The aim of this study is to describe the worldwide clinical and diagnostic work-up and management of AA in surgical departments.info:eu-repo/semantics/publishedVersio

Performance and muscle activity during a high-intensity intermittent task after the ingestion of sodium bicarbonate: A randomized, double-blind, placebo-controlled, crossover study

The aim of the present study was to determine whether the ingestion of sodium bicarbonate (NaHCO3) promotes changes in strength, muscle activity, and perceived exertion in trained individuals following high-intensity intermittent exercise. Twelve trained men were enrolled in a randomized, double-blind, crossover study. Each participant underwent two interventions with a 14-day washout period: i) alkalosis (ALK) – administration of gelatinous capsules containing 0.3 g.kg-1 of NaHCO3; ii) placebo (PLA) – administration of capsules containing 0.3 g.kg-1 of calcium carbonate (CaCO3). The outcomes (electromyographic activity of the quadriceps, peak torque, pH, lactate, scales of perceived effort and pain) were collected during a dynamic high-intensity intermittent protocol performed on an isokinetic dynamometer. Repeated-measures ANOVA revealed no differences between conditions for any of the outcomes analysed. Based on the present findings, the ingestion of sodium bicarbonate does not promote changes in muscle activity, strength of the quadriceps, or perceptions of effort and pain in trained individuals during high-intensity intermittent exercise on an isokinetic dynamometer

Analysis toxicity by different methods and anxiolytic effect of the aqueous extract Lippia sidoides Cham.

Abstract Lippia sidoides Cham. (Verbenaceae) is a species often mentioned in traditional medicine due to the medicinal properties attributed to its leaves, which include antibacterial, antifungal, acaricidal and antioxidant. Several of these actions have been scientifically proven, according to reports in the literature; however, little is known about toxicological aspects of this plant. This work included studies to determine the chemical composition and toxicity tests, using several methods aiming to evaluate the safety for use of the aqueous extract of L. sidoides leaves, in addition, the anxiolytic effect on adult zebrafish was investigated, thus contributing to the pharmacological knowledge and traditional medicine concerning the specie under study. The chemical profile was determined by liquid chromatography coupled to mass spectrometry-HPLC/MS with electrospray ionization. Toxicity was evaluated by zebrafish, Drosophila melanogaster, blood cells, and Artemia salina models. 12 compounds belonging to the flavonoid class were identified. In the toxicity assays, the observed results showed low toxicity of the aqueous extract in all tests performed. In the analysis with zebrafish, the highest doses of the extract were anxiolytic, neuromodulating the GABAa receptor. The obtained results support the safe use of the aqueous extract of L. sidoides leaves for the development of new drugs and for the use by populations in traditional medicine
