This paper aims to provide an update on the main aspects of sepsis, a very relevant health care issue. A number of hypotheses have been proposed to explain its origin, involving interactions between microorganisms and the innate immune system, inflammation/immune mediation and the coagulation system. The clinical features of sepsis are variable and depend on the primary site of infection. The identification of early signs and symptoms is crucial for starting therapeutic measures fundamentally based on volume resuscitation, antibiotic therapy, use of steroids, anticoagulant therapy, biologic viability maintenance interventions and nutritional support.
Malaria is one of the world's leading parasitic diseases and affects a considerably large number of people. Considering the epidemiological reach of Plasmodium falciparum, which is almost always responsible for the most severe cases of malaria, a discussion of the clinical features and therapeutic interventions is important. In the cases of patients with severe malaria, admission to an intensive care unit is mandatory to reduce complications. To have an impact on survival rates, treatment with antimalarial drugs and supportive measures should be initiated as quickly as possible. The aim of this article is to discuss the components of severe malaria, with an emphasis on its clinical features and treatment.
RESUMO
Diante das atuais demandas sociais, tornou-se imprescindível para a educação médica a transição-Learning.-Medical Students.-Medical Education.
ABSTRACT
Given current social demands, it has become essential for medical education to break from the traditional model of biological reductionist and training based only at hospitals and redefine itself towards a holistic care (integrality). The construction of new training practices in health with the use of new outdoor scenarios, in partnership with (Unified National Health System -SUS), assumed a key role.
In 2005 the Centro Universitário Serra dos Órgãos (Unifeso) incorporated into its curriculum the
Problem-Based Learning and the insertion of medical undergraduates into Basic Health Units
The systemic inflammatory response represents the core pathogenic event of sepsis, underlying clinical manifestations and laboratory findings in patients. Numerous studies have shown that CD4+CD25+ T lymphocytes, also known as regulatory T lymphocytes (Treg), participate in the development of sepsis due to their ability to suppress the immune response. The present article discusses the role of Treg lymphocytes in sepsis based on a specific search strategy (Latin American and Caribbean Health Sciences / Literatura Latino-americana e do Caribe em Ciências da Saúde-LILACS, PubMed, and Scientific Electronic Library Online-SciELO) focusing on two main topics: the participation of Treg cells in inflammation and immunity as well as perspectives in the computational physiological investigation of sepsis.
The increased knowledge regarding proteomic analysis techniques has allowed for better understanding of the molecular bases related to the identification of cell signaling, modifying protein, and post-translational modification pathways, in addition to the characterization of specific biological markers. Thus, documenting certain proteins expressed in sepsis is a promising approach to elucidate pathophysiological, diagnostic, therapeutic, and prognostic aspects in this condition with a purpose of applying them to clinical practice. Although the studies are still preliminary, proteomics may offer good benefits for the better management of septic patients. Thus, this article aims to introduce a short review of the applications of proteomic studies to sepsis.
This research corroborated that these nosocomial infections are a relevant medical problem in our context. The most prevalent bacterial infections in the lower respiratory tract of ventilated patients were by Acinetobacter spp., Pseudomonas spp. and Klebsiella spp. The panel of antibiotics used as preventive therapy was not the solution of infections and probably induced drug-resistance mechanisms in these isolated microorganisms.
Erucism is a skin reaction to envenomation from certain poisonous caterpillar bristles. In Brazil, most reports of erucism provoked by Lonomia caterpillars are from the southern region. Most manifestations of erucism are local and include burning pain, itching, local hyperthermia and, rarely, blisters (benign symptoms with spontaneous regression in a few hours). General symptoms such as nausea and vomiting, headache, fever, myalgia, abdominal pain and conjunctivitis may also occur. Uncommon symptoms include arthritis, coagulation disorders (manifested as bruising and bleeding), intracerebral hemorrhage and acute renal failure, which comprise serious complications. The present study reports the case of 60-year-old patient from Rio de Janeiro state, Brazil, who came into contact with a caterpillar and developed, a few days later, chronic renal disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
