Gamasoidose ilustrada: do ninho à dermatoscopia

Gamasoidosis (acariasis, avian-mite dermatitis or bird-mite dermatitis) is a challenging diagnosis that is becoming more common because of the frequent use of window air conditioners in tropical countries. These devices may serve as shelters for nests of urban birds such as pigeons. Dermatologists should become familiar with this infestation to establish the correct diagnosis and treatment

Síndrome de Morgagni-Stewart-Morel: Morgagni-Stewart-Morel syndrome

Introdução: a síndrome de Morgagni Stewart Morel é uma entidade clínica rara. Sua principal característica é a hiperostose frontal interna. Além disso, conta com alterações endócrinas​ metabólicas e psiquiátricas. Pode estar acompanhada de obesidade, diabetes mellitus e hirsutismo. Possui maior prevalência na população feminina. Apresentação do caso: paciente do sexo feminino, 65 anos, obesa em menopausa há 12 anos. Relata em consulta queixa de cefaleia em aperto na região frontal há cerca de 6 anos. A mesma vem se intensificando gradativamente e há 01 semana a dor não é sanada mesmo com o uso de anti-inflamatórios ou analgésicos orais. Discussão: a síndrome de Morgagni-Stewart-Morel consiste em uma condição rara, caracterizada pela presença de Hiperostose Frontal Interna (HFI) associada a alterações metabólicas, psiquiátricas e endócrinas. Sua definição não é uniforme devido a diversidade de sintomas e a sua variabilidade em cada indivíduo. Possui incidência maior no sexo feminino e com idade acima de 50 anos, sua etiologia ainda é pouco conhecida. Algumas teorias buscam elucidar o tema como o aumento da leptina, desordem hormonal de andrógenos e há também defensores de uma síndrome genética, ligada ao X com penetrância variável. Conclusão: diante da raridade de casos da síndrome, o diagnóstico geralmente ocorre de modo incidental, por meio da correlação entre sintomatologia variada e investigação radiológica. Sua abordagem terapêutica é predominantemente sintomática, de modo a se optar por conduta cirúrgica em casos reservados

Avulsão da Espinha Ilíaca anterosuperior pós traumática : Post-traumatic anterosuperior Iliac Spine avulsion

Introdução: As lesões ósseas da pelve e quadril são raras, e ocorrem principalmente na faixa etária de 8 a 14 anos, e estão relacionadas à prática de atividades físicas de alto impacto e repetitivas. As fraturas por avulsão das espinhas ilíacas superior e inferior e tuberosidade isquiática tem maior incidência devido ao aumento da prática de desportos nessa faixa etária. Apresentação do caso: I.P.M, masculino, 17 anos de idade, procurou o serviço do Hospital Geral de Goiás (HGG), referindo dor iniciada há 30 dias na face anterior do quadril esquerdo, durante partida de futebol. Refere aumento da intensidade da dor, e ao exame físico possui equimose local, edema e dor em quadril esquerdo. Ao raio x apresentou fratura da espinha ilíaca ântero superior à esquerda. Discussão: Essa lesão geralmente ocorre como resultado da contração súbita, vigorosa ou repetitiva do músculo sartório e tensor da fascia lata. Os sintomas mais comumente relatados são dor intensa associada a “estalos” na hemipelve afetada, edema, limitação funcional ipsilateral e equimoses. O tratamento é preferencialmente conservador, durando, em média, de 6 a 8 semanas. Já a cirurgia, é indicada para casos em que há desvio de mais de três centímetros ou com lesão neurovascular associada. Conclusão: Seu tratamento adequado, feito precocemente, torna-se importante na prevenção de lesões permanentes e complicações futuras. Na maioria das vezes, o tratamento e conservador, excetuando-se os casos de desvio fragmentário superior a três centímetros

A global experiment on motivating social distancing during the COVID-19 pandemic

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

Data from: Seed dispersal syndromes in the Madagascan flora: the unusual importance of primates

Madagascar is one of the most threatened biodiversity hotspots, and protection of its biodiversity is becoming increasingly urgent as deforestation of the island continues. For the long-term success of conservation efforts it is essential that key ecological processes, such as seed dispersal, are protected and restored. Therefore, the identification of ecological gaps is a vital task. For Madagascar, only little is known about plant–animal interactions, and traditional methods of ecological research are too time-consuming to provide crucial information about breakdowns in these interactions. To identify likely dispersal gaps we therefore used a theoretical approach to analyse plant–disperser interactions in Madagascar. We used data science tools to impute missing data on relevant plant traits to subsequently predict the most likely dispersal agents for each of Madagascar’s endemic plant species. We found that 38% of the endemic species (N = 8,784) are endozoochorous, and among these 26–41% display a primate syndrome and 17–19% a bird syndrome (depending on the definition of syndromes). This lower percentage of endozoochorous species and higher percentage of species with a primate syndrome in Madagascar compared to other tropical areas reflects the unusual disperser guild on the island. Only five bird species but 20 lemur species are frugivorous, and 16 of those lemur species are currently threatened with extinction. The disappearance of frugivorous lemurs would significantly change the vegetation dynamics of Madagascar’s ecosystems, and a high proportion of Madagascar’s endemic plants would enter an extinction vortex

Madagascan plant traits

Data on traits of endemic Madagascan plant species before and after imputation of missing values (using multivariate imputations by chained equations). Data were compiled from the literature, public databases (Madagascar Catalogue, 2013) and examination of herbarium specimens at the Royal Botanic Gardens, Kew (2,519 specimens) and at the Muséum National d’Histoire Naturelle, Paris (364 specimens)
