RESUMO

Objectives: This study aimed to evaluate the clinical and serological profile in systemic sclerosis (SSc) by comparing females and males. Patients and methods: This retrospective study was conducted with 215 SSc patients (193 females, 22 males; mean age: 50.1±14.5 years; range, 16 to 88 years) between September 2005 and September 2020. Disease severity was calculated by the Medsger severity score. Males and females were compared for clinical and serological markers. Results: Females more frequently had esophageal involvement (p=0.003), telangiectasias (p=0.03), and antinuclear antibodies (p=0.04). Males more frequently had fingertip scars (p=0.03), digital ulcers (p=0.006), and a worse median Medsger severity score (6 in males vs. 4 in females, p=0.05). Conclusion: In the studied sample, males had more severe disease than females with greater repercussions in periferic circulatory system.

RESUMO

Cutaneous fibrosis is one of the main features of systemic sclerosis (SSc). Recent findings correlated abnormal collagen V (Col V) deposition in dermis with skin thickening and disease activity in SSc. Considering that Col V is an important regulator of collagen fibrillogenesis, understanding the role of Col V in the first two years of the skin fibrosis in SSc (early SSc) can help to determine new targets for future treatments. In this study, we analyzed the morphological, ultrastructural and molecular features of α1(V) and α2(V) chains and the expression of their coding genes COL5A1 and COL5A2 in collagen fibrillogenesis in early-SSc. Skin biopsies were obtained from seven consecutive treatment-naïve patients with SSc-related fibrosis and four healthy controls. Our data showed increased α1(V) and α2(V) chain expression in the reticular dermis of early-SSc patients; however, immunofluorescence and ultrastructural immunogold staining determined a significant decreased expression of the α1(V) chain along the dermoepidermal junction in the papillary dermis from early-SSc-patients in relation to the control (12.77 ± 1.34 vs. 66.84 ± 3.36; p < 0.0001). The immunoblot confirmed the decreased expression of the α1(V) chain by the cutaneous fibroblasts of early-SSc, despite the increased COL5A1 and COL5A2 gene expression. In contrast, the α2(V) chain was overexpressed in the small vessels (63.18 ± 3.56 vs. 12.16 ± 0.81; p < 0.0001) and capillaries (60.88 ± 5.82 vs. 15.11 ± 3.80; p < 0.0001) in the reticular dermis of early-SSc patients. Furthermore, COLVA2 siRNA in SSc cutaneous fibroblasts resulted in a decreased α1(V) chain expression. These results highlight an intense decrease in the α1(V) chain along the dermoepidermal junction, suggesting an altered molecular histoarchitecture in the SSc papillary dermis, with a possible decrease in the expression of the α1(V)3 homotrimeric isoform, which could interfere with the thickening and cutaneous fibrosis related to SSc.

RESUMO

La acrodisostosis es una displasia esquelética rara, de herencia autosómica dominante, que se caracteriza por la presencia de disostosis facial y periférica, talla baja y diferentes grados de obesidad. La acrodisostosis de tipo 1, secundaria a la mutación heterocigota en el gen PRKAR1A (17q24.2), se caracteriza por la asociación de resistencia hormonal múltiple con anomalías esqueléticas. Su incidencia está infradiagnosticada debido a que comparte rasgos clínicos y de laboratorio con otras entidades como el seudohipoparatiroidismo. Presentamos el caso de una niña de 8 años, con acrodisostosis tipo 1, confirmada mediante estudio genético. Además del fenotipo característico descrito, la talla baja y la resistencia hormonal, la paciente presentó una afectación progresiva de la función pulmonar: un patrón pulmonar obstructivo no reversible. En la literatura revisada, no se han encontrado otros casos que describan esta asociación entre acrodisostosis y afectación respiratoria.

Acrodysostosis is a rare skeletal displasia, of autosomal dominant inheritance, characterized by the presence of facial and peripheral dysostosis, short stature and obesity. Type 1 acrodysostosis is secondary to a mutation in the PRKAR1A (17q24.2) gene, which results in multi hormonal resistance and skeletal anomalities. This syndrome is under-diagnosed as it shares analytical and clinical characteristics with other entities, such as pseudohypoparathyroidism. We report the case of an eight-year-old girl with genetically confirmed type 1 acrodysostosis. In addition to the characteristic phenotype described, the short stature and the hormonal resistance, the patient suffered a progressive lung function deterioration: an irreversible pulmonary obstructive pattern. We have not found in previous literature cases reporting an association between acrodysostosis and lung function impairement.

RESUMO

OBJECTIVE: To study a sample of rheumatoid arthritis (RA) patients for their gynecological/obstetric history and compare them to controls to determine their influences on number of pregnancies, menarche, menopause and reproductive years following RA onset. METHODS: This is a cross-sectional study of 122 RA patients and 126 controls. Patients and controls were questioned about age of menarche, age of menopause, number of pregnancies and abortions. Reproductive years were calculated as the difference between age at menopause and age at menarche. For comparison, we used the Mann-Whitney, unpaired t, chi-squared, and Spearman tests. The adopted significance was 5%. RESULTS: In the RA patients with disease beginning in the postmenopausal years, the period of reproductive years (age at menopause - age of menarche) showed a positive correlation with age at disease onset (rho = 0.46; 95% confidence interval [CI] = 0.20-0.55 with p = 0.0008). The number of pregnancies was higher in patients with postmenopausal disease onset when compared with those with premenopausal disease onset (median of 3 with interquartile range [IQR] = 2-4 versus median of 2 with IQR = 1-3; p = 0.009), and RA patients had more pregnancies than controls (p = 0.0002). CONCLUSION: The present study shows that, in our population, the duration of reproductive years and the number of pregnancies are linked to the onset of RA.

OBJETIVO: Estudar uma amostra de pacientes com artrite reumatoide (AR), com investigação da história ginecológica e obstétrica, comparando-a com controles, visando conhecer suas influências no número de gestações, menarcas, menopausa e anos reprodutivos no início da AR. MéTODOS: Trata-se de um estudo transversal de 122 pacientes com AR e 126 controles. Pacientes e controles foram questionados sobre idade da menarca, idade da menopausa, número de gestações e abortos. Os anos reprodutivos foram calculados com a diferença entre a idade da menopausa e a idade da menarca. Para comparação, foram utilizados Mann Whitney, Teste t não pareados, Teste qui-quadrado e teste de Spearman. A significância adotada foi de 5%. RESULTADOS: Nas pacientes com AR e início da doença na pós-menopausa, o período de anos reprodutivos (idade da menopausa - idade da menarca) apresentou correlação positiva com a idade de início da doença (rho = 0,46; intervalo de confiança de 95% [IC95%] = 0,20­0,55 com p = 0,0008). O número de gestações foi maior nas pacientes com início da doença no período pós-menopausa quando comparadas às pacientes em pré-menopausa (mediana de 3 com intervalo interquartil [IIQ] = 2­4 versus mediana de 2 com IIQ = 1­3; p = 0,009). Nas pacientes com AR, foi observado um maior número de gestações do que no grupo controle (p = 0,0002). CONCLUSãO: O presente estudo mostra que, em nossa população, a diminuição dos anos reprodutivos e o alto número de gestações estão relacionados ao surgimento da AR.

RESUMO

Resumen El artículo presenta un estudio de caso cuya objetivo es mejorar las condiciones de accesibilidad web de un dispositivo de comunicación pública de ciencia y tecnología titulado Dispositivo Hipermedial Dinámico Memoria y experiencia Cossettini. El mismo, publica en Acceso Abierto documentos digitalizados del Archivo pedagógico Cossettini conteniendo una gran cantidad de elementos estéticos visuales. Desde el marco teórico se sostiene que la elaboración colaborativa de objetos digitales multimodales contextualizados podría posibilitar a quienes participan del DHD MyECossettini una experiencia sensible/accesible de exploración, interpretación y recreación no excluyente de los archivos patrimoniales digitalizados, sin desmedro de lo singular y significativo de la fuente original. En este sentido, se ha propuesto la Accesibilidad-DHD basada en los principios de Percepción, Comprensión, Acción y Flexibilidad. En lo metodológico, se abordó el análisis y desarrollo de objetos digitales accesibles con un enfoque socio-técnico e interdisciplinar en atención al principio de percepción. Los resultados alcanzados constatan que las alternativas accesibles elaboradas habilitan nuevos canales perceptivos y proporcionan información contextual que constituye un valor agregado para todas las personas. Finalmente, se concluye que participar de la Accesibilidad-DHD no requiere necesariamente de experticia en informática, habilitando a que cada persona, desde su lugar, colabore en garantizar el acceso equitativo a la información. No obstante se advierte que, el desafío más complejo se presenta en la construcción de una toma de conciencia colectiva activa que asuma con responsabilidad de garantizar el Derecho Humano a habitar sin exclusiones el ciberespacio.

Abstract This article presents a case study with the aim to improve the conditions of web accessibility of a science and technology public communication device, "Dynamic Hypermedia Device, Memoria y Experiencia Cossettini". It publishes in Open Access digitized documents from the "Cossettini pedagogical archive" containing a large number of visual aesthetic elements. From the theoretical framework, the collaborative elaboration of contextualized multimodal digital objects could allow those who participate in the DHD MyECossettini a sensitive/accessible experience of exploration, interpretation and non-exclusive recreation of digitized heritage archives, without detriment to the singular and significant of the original source. Therefore, it is proposed DHD-Accessibility based on the principles of Perception, Comprehension, Action and Flexibility. Methodologically, the analysis and development of accessible digital objects are developed with a socio-technical and interdisciplinary approaches, focused on the principle of perception. The results achieved confirm that the accessible alternatives developed enable new perceptual channels and provide contextual information that constitutes added value for all people. Finally, it is highlighted that participating in "DHD-Accessibility" does not necessarily require IT expertise, enabling each person, from their place, to collaborate in guaranteeing equitable access to information. However, it is noted that the most complex challenge is presented in the construction of an active collective awareness that assumes with responsibility to guarantee the Human Right to inhabit cyberspace without exclusions.

RESUMO

Racional: Esclerose sistêmica (ES) e lúpus eritematoso sistêmico (LES) são doenças difusas do tecido conjuntivo que, quando agregadas, geram a síndrome de sobreposição (SP ES-LES), condição ainda não claramente caracterizada do ponto de vista clínico e epidemiológico. Objetivo: Caracterizar clínica e epidemiologicamente pacientes com SP ES-LES. Método: Trata-se de um estudo retrospectivo, descritivo de análise de prontuários. Coletaram-se dados demográficos, clínicos, laboratoriais e exames de imagens de pacientes com SP ES-LES.Resultados: O perfil encontrado foi o de mulher, jovem, caucasiana, não tabagista e com forma de limitada de ES. Foram comuns: fenômeno de Raynaud; acometimento gastroesofágico, pulmonar e cutâneo; anemia; linfopenia; FAN pontilhado grosso; anti-RNP; anti-Ro e anti-Sm. Nunca ter fumado foi achado protetor para serosite e lesões discoides, como também foram significativas associações anti-Scl-70 com lúpus discoide, anti-La com síndrome de Sjögren e anti-DNA com úlceras digitais. Conclusão: A SP ES-LES é multissistêmica, com aspectos clínicos predominantes de ES. Devido à grande prevalência de envolvimento pulmonar nesses pacientes, justifica-se o rastreamento de possíveis complicações.

Background: Systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are diffuse autoimmune diseases of the connective tissue that when combined generate the SSc-SLE overlap syndrome (OS), condition without consistent epidemiological data. Objective: Characterize clinical and epidemiological data in patients with OS SSc-SLE. Method: This is a retrospective descriptive study of medical records. Demographic, clinical, laboratory data and image exams of older patients with SSc-SLE were collected. Results: Epidemiological profile was of female patients, young, caucasian, non-smoker with limited ES. Raynaud's phenomenon, gastroesophageal, pulmonary and skin disorders, anemia and lymphopenia were common as well as thick dotted ANA; anti-RNP; anti-Ro and anti-Sm. No smoking was protective for serositis and for discoid lesions, as well as significant associations of anti-Scl-70 with discoid lupus, anti-La with Sjogren's syndrome and anti-DNA with digital ulcers were found. Conclusion: OS SSc-SLE is multisystemic with clinical predominance of SSc. Due to high prevalence of lung involvement, screening for such possible complication is justified.
