IL36G genetic variant is independently associated with susceptibility, severity and joint involvement in psoriasis.

Psoriasis (PsO) is a chronic, immune-mediated, inflammatory and polygenic dermatosis associated with both physical and psychological burden that can be triggered by injury, trauma, infections and medications. The etiology of PsO is not fully elucidated but genetic, epigenetic and environmental factors are all likely to play a role. A case-control study was carried out to evaluate the frequency of the IL36G C>T (rs13392494) and the IL36G A>G (rs7584409) variants and their association with susceptibility, joint involvement and severity of PsO. The study included 154 patients with PsO and 154 controls from Brazilian population. The severity of PsO was assessed by the Psoriasis Area and Severity Index (PASI). The IL36G (rs13392494 and rs7584409) variants were genotyped by allelic discrimination assay using the real-time polymerase chain reaction. The association between the IL36G genetic variants and the study variables was analyzed in allelic, dominant, codominant, overdominant, recessive, and haplotype models. The main results were that PsO patients were older (p < 0.001) and had higher body mass index (p < 0.001) than controls; 95.8% of the patients had plaque PsO, 16.1% had psoriatic arthritis (PsA), and 27.9% had PASI > 10. The IL36G rs1339294 variant showed no association with PsO in all genetic models while the IL36G rs7584409 variant showed a protective effect in PsO. However, the G allele of the IL36G rs7584409 in the dominant model was positively associated with PASI > 10 (p = 0.031). Moreover, patients with the GG genotype of the IL36G rs7584409 variant had about 5.0 times more chance of PsA than those with the AA genotype (p = 0.014). Regarding the haplotypes, the C/A in a recessive model (CACA versus C/G and T/A carriers) was associated with PsO (p = 0.035) while the C/G haplotype in a dominant model (C/A carriers versus C/G and T/A carriers) showed a protective effect for PsO (p = 0.041). In conclusion, the G allele of the IL36G rs7584409 variant was associated with protection to PsO; however, in patients with PsO, this same allele was associated with moderate to severe disease and PsA. These results suggest that the IL36G rs7584409 variant may be used as a possible genetic biomarker to predict severity and joint involvement of PsO.

Por que e como reformar um currículo inovador? Um relato de experiência de Londrina / Why and how to reform an innovative curriculum? An experience report from Londrina

Resumo: Introdução: O curso de graduação em Medicina da Universidade Estadual de Londrina foi o segundo do Brasil a adotar currículo integrado e Aprendizagem Baseada em Problemas (PBL). Apesar de seu currículo inovador ter servido de referência a outras escolas, avaliações recentes mostraram a necessidade de reforma. Relato de experiência: As avaliações sistemáticas do curso indicaram os seguintes problemas: dificuldade de adaptação dos ingressantes à primeira série; desorganização da sequência de conteúdos ao longo do curso; falta de motivação docente para as atividades da primeira à quarta série; necessidade de incluir tópicos obrigatórios e novas tendências; e desgaste da metodologia (PBL) a partir da terceira série. Um amplo trabalho de reforma curricular foi iniciado, baseado na construção coletiva, culminando em mudanças, como: o desenho de uma primeira série mais acolhedora por meio da inclusão de nivelamento de ciências básicas e mentoria; a reorganização cronológica dos conteúdos; o redesenho dos módulos, agora organizados ao redor de grandes áreas ou especialidades afins; a adoção de metodologias ativas mais motivadoras; e a inclusão de novos conteúdos. Discussão: A adoção de novas metodologias ativas em substituição à PBL em alguns momentos apresenta vantagens estratégicas. A Aprendizagem Baseada em Equipes (TBL), mais estruturada que a PBL, pode ajudar na adaptação dos ingressantes à primeira série e facilitar a realização de metodologias ativas num contexto de escassez de docentes. A Aprendizagem Baseada em Casos (CBL) é mais motivadora e pode ser mais efetiva para desenvolver habilidades de raciocínio clínico nas séries pré-internato. Conclusão: O novo currículo, que incorpora as mudanças mencionadas, foi implantado em 2022. Novas avaliações mostrarão se as mudanças trarão melhorias ao curso em termos de adaptação, motivação e resultados de aprendizagem.

Abstract: Introduction: The undergraduate medical course of the State University of Londrina was the second in Brazil to adopt an integrated curriculum and Problem-Based Learning (PBL). Despite its innovative curriculum, which became a reference for other schools, new assessments showed the need to reform it. Experience Report: Systematic course evaluations showed some issues: difficulties in adaptation of new students attending the first year; disorganized sequence of contents throughout the course; teachers' lack of motivation for activities from first to the fourth years; need to include new contents; and deterioration of the methodology (PBL) in third and fourth years. A wide collective effort for curricular reform was initiated, which led to important changes, such as: a more welcoming first year, by including mentoring and activities for the leveling of basic knowledge; chronological reorganization of contents; redesign of modules around great areas of knowledge or related specialties; adoption of new and more motivating active learning and teaching methodologies, and the inclusion of new topics/trends. Discussion: The adoption of other active learning and teaching methodologies present strategic advantages in replacement for PBL. Team-Based Learning (TBL) is a more structured method than PBL, so it can help newcomers to adapt to the first year and make it easier to implement active methodologies in a context of teacher shortage. Case-Based Learning (CBL) generates higher motivation and can be more effective to foster the development of clinical reasoning skills in the preclinical years. Conclusion: The new curriculum, incorporating the changes described above, started in 2022. Further evaluations will show whether the changes will improve the course in terms of adaptability, motivation and learning outcomes.

Cell adhesion molecules, plasminogen activator inhibitor type 1, and metabolic syndrome in patients with psoriasis.

The objective of this study is to delineate the cellular adhesion molecule (CAM) profile and plasminogen activator inhibitor type 1 (PAI-1), and their association with metabolic syndrome (MetS) and carbohydrate metabolism biomarkers in psoriasis patients with mild and moderate severity. Sixty-seven patients with psoriasis as well as 102 healthy subjects were recruited. Insulin and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), but not glucose, were significantly higher in psoriasis than in controls. Psoriasis was characterized by increased plasma levels of platelet endothelial cell adhesion molecule 1 (PECAM-1), vascular cell adhesion molecule 1 (VCAM-1), intercellular adhesion molecule 1 (ICAM-1), E-selectin, and PAI-1 as compared with controls. Psoriasis diagnosis could explain 59.0% of CAM and PAI-1 variance, with a particularly strong impact on E-selectin (45.6%), VCAM-1 (32.7%), and PAI-1 (24.8%). Subjects with MetS showed significantly higher E-selectin and PAI-1 than those without MetS. Using VCAM-1, E-selectin, PAI-1 (all positively), and P-selectin (inversely) in a binary regression equation, it was found that 87.6% of all patients were correctly classified with a sensitivity of 92.5% and a specificity of 84.3%. CAM and PAI-1 were correlated with carbohydrate metabolism biomarkers (glucose, insulin, and HOMA-IR). In conclusion, CAM levels are associated with psoriasis diagnosis and MetS may influence E-selectin and PAI-1 concentrations. More studies are needed to verify the causality among these factors, as well as their relation to the different degrees of disease severity.

Dermatosis neglecta: a report of two cases.

Few cases of dermatosis neglecta have been reported in the medical literature, although the diagnosis is well-known to dermatologists. Recognizing this condition avoids unnecessary, aggressive diagnostic and therapeutic procedures. This case report discusses two cases of this condition in female patients in whom the dermatosis developed as a result of deliberate or unconscious neglect of personal hygiene.

Dermatitis neglecta: relato de dois casos / Dermatosis neglecta: a report of two cases

Poucos são os casos de dermatitis neglecta relatados na literatura, apesar de o diagnóstico ser conhecido pelos dermatologistas. Reconhecer o quadro evita condutas diagnósticas e terapêuticas agressivas e desnecessárias. Os autores relatam dois casos de pacientes do sexo feminino nos quais a dermatite se desenvolveu como resultado intencional ou não de negligência com o asseio pessoal.
