GLUCOCORTICOID USE IN STEVENS-JOHNSON SYNDROME AND TOXIC EPIDERMAL NECROLYSIS CASES IN HOSPITAL NOSSA SENHORA DA CONCEIÇÃO - MARCH 2007 TO AUGUST 2014

Introdução: A síndrome de Stevens-Johnson e a necrólise epidérmica tóxica (NET) são reações cutâneas severas, associadas a lesões mucosas e comprometimento sistêmico. Os glicocorticoides foram empregues por muitos anos no tratamento da síndrome de Stevens-Johnson/necrólise epidérmica tóxica, mas não há evidências que sustentem esta conduta.Objetivo: Avaliação da mortalidade em casos de síndrome de Stevens-Johnson/necrólise epidérmica tóxica em um grupo de pacientes que fez uso de glicocorticoides sistêmico e em outro grupo não fez uso.Objetivo secundário: Descrição da população estudada; avaliação de infecção secundária e complicações extra-cutâneas nos dois grupos de pacientes.Material e Métodos: Coorte retrospectiva de pacientes avaliados por meio de consultorias solicitadas ao Serviço de Dermatologia do Hospital Nossa Senhora da Conceição, bem como pelo diagnóstico na internação ou óbito, durante o período de Março de 2007 a Agosto de 2014.Resultados: Mortalidade foi de 63.2% no grupo que usou corticoide e 9,1% no grupo que não usou corticoide, com p valor de 0,005 (IC 95% 1.79-163.8). Análise multivariada ajustada pelo SCORTEN demonstrou apenas uma tendência, com odds ratio para mortalidade no grupo de pacientes que usou glicocorticoides sendo de 7.38 (IC 95% 0.87-161.43) e p valor de 0.06.Conclusão: Este estudo sugere uma tendência de malefício relacionado ao uso de glicocorticoides para o tratamento dessas doenças, principalmente no que diz respeito à mortalidade.Introduction: Stevens-Johnson syndrome and toxic epidermal necrolysis are severe skin reactions associated with mucosal lesions and systemic involvement. Glucocorticoids were used for many years in the treatment of Stevens-Johnson syndrome / Toxic Epidermal Necrolysis, but there is no evidence to support this approach.Objective: Assessment of mortality in Stevens-Johnson syndrome/Toxic Epidermal Necrolysis cases in a group of patients that used systemic glucocorticoids and another group who did not.Secondary objective: Description of the study population; review of secondary infection and extra-cutaneous complications in both groups of patients.Material and Methods: Retrospective cohort of patients selected by consulting requested to the Dermatology Service of the Hospital Nossa Senhora da Conceição, as well as the diagnosis at admission or death, during the period March 2007 to August 2014.Results: Mortality rate was 63.2% in the group that used corticosteroids and 9.1% in the group that did not use steroids, with p value 0.005 (95% CI 1.79-163.8). Multivariate analysis adjusted for SCORTEN showed only a trend for harm, with an odds ratio for mortality in patients who used glucocorticoids being of 7:38 (95% CI 0.87-161.43) and p value 0.06.Conclusion: This study suggests a trend for harm associated with glucocorticoids use for treatment of these diseases, especially in regard to mortality

Trypsin-like serine peptidase profiles in the egg, larval, and pupal stages of Aedes albopictus

BACKGROUND: Aedes albopictus, a ubiquitous mosquito, is one of the main vectors of dengue and yellow fever, representing an important threat to public health worldwide. Peptidases play key roles in processes such as digestion, oogenesis, and metamorphosis of insects. However, most of the information on the proteolytic enzymes of mosquitoes is derived from insects in the adult stages and is often directed towards the understanding of blood digestion. The aim of this study was to investigate the expression of active peptidases from the preimaginal stages of Ae. albopictus. METHODS: Ae. albopictus eggs, larvae, and pupae were analyzed using zymography with susbtrate-SDS-PAGE. The pH, temperature and peptidase inhibitor sensitivity was evaluated. In addition, the proteolytic activities of larval instars were assayed using the fluorogenic substrate Z-Phe-Arg-AMC. RESULTS: The proteolytic profile of the larval stage was composed of 8 bands ranging from 17 to 130 kDa. These enzymes displayed activity in a broad range of pH values, from 5.5 to 10.0. The enzymatic profile of the eggs was similar to that of the larvae, although the proteolytic bands of the eggs showed lower intensities. The pupal stage showed a complex proteolytic pattern, with at least 6 bands with apparent molecular masses ranging from 30 to 150 kDa and optimal activity at pH 7.5. Peptidases from larval instars were active from 10°C to 60°C, with optimal activity at temperatures between 37°C and 50°C. The proteolytic profile of both the larval and pupal stages was inhibited by phenyl-methyl sulfonyl-fluoride (PMSF) and Nα-Tosyl L-lysine chloromethyl ketone hydrochloride (TLCK), indicating that the main peptidases expressed during these developmental stages are trypsin-like serine peptidases. CONCLUSION: The preimaginal stages of Ae. albopictus exhibited a complex profile of trypsin-like serine peptidase activities. A comparative analysis of the active peptidase profiles revealed differential expression of trypsin-like isoforms among the preimaginal stages, suggesting that some of these enzymes are stage specific. Additionally, a comparison of the peptidase expression between larvae from eggs collected in the natural environment and larvae obtained from the eggs of female mosquitoes maintained in colonies for a long period of time demonstrated that the proteolytic profile is invariable under such conditions

O transtorno dissociativo de identidade compreende uma condição psicológica complexa provavelmente causada por inúmeros fatores, envolvendo trauma grave na primeira infância, como abuso sexual, físico ou emocional repetitivo e extremo e repetitivo. Este estudo teve como objetivo identificar as terapias voltadas para o tratamento do transtorno dissociativo de identidade. Para isso, foi realizada uma revisão integrativa de literatura, selecionando fontes a partir das bases de dados Medline e Lilacs. A partir da análise qualitativa de dados, concluiu-se que há vários tipos de terapias para o tratamento de pessoas transtorno dissociativo de identidade, devendo essas serem aplicadas conforme cada realidade. Nos estudos, foram identificados os modelos de tratamento psicanalítico relacional, fásico, psicoativo e psicotraumatológico. Em todos esses, foram registrados resultados satisfatórios, tais como a diminuição na dissociação e o aumento do funcionamento adaptativo do paciente, revelando a possibilidade de desconstruir crenças solidamente cultivadas e trazendo esperança aos pacientes no sentido de amenizar ou superar esse transtorno e garantir uma boa interação social

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

São João del Rey, MG, Brasil.Aedes albopictus is a vector for several fatal arboviruses in tropical and sub-tropical regions of the world. The midgut of the mosquito is the first barrier that pathogens must overcome to establish infection and represents one of the main immunologically active sites of the insect. Nevertheless, little is known about the proteins involved in the defense against pathogens, and even in the processing of food, and the detoxification of metabolites. The identification of proteins exclusively expressed in the midgut is the first step in understanding the complex physiology of this tissue and can provide insight into the mechanisms of pathogen-vector interaction. However, identification of the locally expressed proteins presents a challenge because the Ae. albopictus genome has not been sequenced
