Sporotrichosis | Fungal Diseases | CDC

SymptomsRisk & PreventionSourcesDiagnosis & TestingTreatmentStatisticsThe symptoms of sporotrichosis depend on where the fungus is growing in the body. Contact your healthcare provider if you have symptoms that you think are related to sporotrichosis. Sporotrichosis usually affects the skin or tissues underneath the skin. The first symptom of cutaneous (skin) sporotrichosisis usually a small, painless bump that can develop any time from 1 to 12 weeks after exposure to the fungus. The bump can be red, pink, or purple, and usually appears on the finger, hand, or arm where the fungus has entered through a break in the skin. The bump will eventually grow larger and may look like an open sore or ulcer that is very slow to heal. Additional bumps or sores may appear later near the original one. Pulmonary (lung) sporotrichosisis rare. Symptoms include cough, shortness of breath, chest pain, and fever. Symptoms of disseminated sporotrichosisdepend on the body part affected. For example, infection of the joints can cause joint pain that may be confused with rhe...Get price

Deaths Attributable to High Body Mass in Brazil

AbstractObjectiveMethodsResultsDiscussionAcknowledgmentsAuthor InformationReferencesTableOur study estimated the proportion of deaths from major noncommunicable diseases (NCDs) that could be prevented in Brazil by reducing population-wide body mass index (BMI) to different counterfactual (optimally theoretical) scenarios. We calculated population-attributable fractions by using BMI data from a representative national survey and relative risks from a published meta-analysis. Reductions in population-wide BMI could prevent 30,715 to 168,431 deaths from NCDs per year in Brazil. Cardiovascular diseases were the most preventable causes of death (5.8%–31.5% deaths prevented). Policies are needed to reduce population-wide BMI in Brazil. TopGet price

Sulfur Hexafluoride (Sulfr hexafluoride) |

IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula gaz sf6) is a compound of sulfur and fluorine and the most potent greenhouse gas known. Several classes of compounds containing fluorine—including the chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), and gaz sf6—are potent greenhouse gases. HCFCs and CFCs are better-known as destroyers of atmospheric ozone, and are regulated under the 1987 Montreal Protocol that has been widely hailed as successful at halting depletion of the ozone layer. Although sf 6 is a potent greenhouse gas and its concentration in the atmosphere is increasing rapidly, its contribution to global warming is much smaller than that of the major greenhouse gases, especially carbon dioxide and methane, because it is present in smaller quantities. sf6 gas is one of the six greenhouse gases regulated under the Kyoto Protocol.Get price
