IgG4-related disease: Case report and 6-year follow-up of an elusive diagnosis mimicking malignancy.

Key Clinical Message: IgG4-related disease is a rare and emerging pathology, characterized by the appearance of pseudotumors. Due to the ability to mimic other pathologies, it is essential to consider it as a differential diagnosis in multisystemic processes. The diagnosis is challenging, requiring a multidisciplinary approach, to minimize the associated morbidity and mortality. Abstract: IgG4-related disease (IgG4-RD) is a rare, emerging, systemic and chronic pathology, characterized by the appearance of pseudotumors resulting from tissue infiltration by IgG4-positive plasma cells that promote eosinophilic inflammation of the tissue with subsequent fibrosis. We present the case of a male, 45-year-old patient, with marked weight loss and skin pallor detected by his family doctor during a child health consultation of his daughter. When questioned, the patient referred complaints of postprandial discomfort in the left hypochondrium with a feeling of fullness, weight loss, chronic fatigue and hyperhidrosis that had lasted for a month. On physical examination, he was pale, and had pain at palpation of the left hypochondrium. Laboratory data showed increased inflammation markers, abdominal ultrasound and CT demonstrated numerous enlarged lymph nodes in the upper quadrants, raising concern for a malignant lymphoproliferative process. Serological, imaging, clinical and laparoscopic excisional biopsy revealed features of IgG4-related disease and excluded malignant lymphoproliferative disease. The immediate response to treatment with oral prednisolone 30 mg/day also contributed for diagnosis confirmation. Due to refractory disease after gradual prednisolone reduction, second-line therapy with rituximab was initiated. Over the 6 years of follow-up, the patient presented multiple exacerbations characterized by the emergence of systemic symptoms, being maintained under close clinical and imaging follow-up by reumathology, infectious diseases, and family medicine specialists.

A Compreensão da Intersubjetividade Entre um Adolescente Suicida e seus Pais Através da Combinação de Métodos na Análise do Discurso / La Comprensión dela intersubjetividadentre un adolescente suicida y sus padres mediante la combinación de métodos en el análisis del discurso / Understanding Intersubjectivity Between a Suicidal Adolescent and His Parents Through the Combination of Methods in Discourse Analysis

Trata-se de um recorte de pesquisa de doutorado em que se intencionou estudar o vínculo intersubjetivo familiar em um adolescente com histórico de tentativa de suicídio, pautando-se nos desejos e defesas. Utilizou-se a combinação de três instrumentos (ADL-AH, ADL-R e o Genograma) para a análise do discurso. Após exame individual dos dados apontados por cada instrumento, realizou-se asanálises comparativas. Inicialmente, confrontou-se os resultados do ADL-AH com o ADL-R conforme a descrição do caso. Em seguida, o Genograma propiciou o entendimento intergeracional da família estudada, confirmou aspectos já levantados e elucidou pontos dos quais o ADL não poderia ter alcançado, embora esse último tenha encontrado discrepâncias no discurso, isto é, aquilo que se pretendia disfarçar ou esconder de forma consciente ou inconsciente. A combinaçãodos três instrumentos trouxe consistência para a investigação no sentido de uma melhor compreensão da intersubjetividade do adolescente, sua família e do comportamento suicida AU

Primary care in supplementary health: assessment of costs in the care of older adult patients with heart diseases.

OBJECTIVES: to identify whether implementing a supplementary Primary Health Care (PHC) system makes it possible to reduce care costs for older adults with heart diseases. METHODS: a retrospective cohort of 223 patients with heart disease aged ≥ 60 years. Data were obtained from medical records and cost databases, assessed for a period of one year before and after PHC implementation. The results were expressed as mean absolute frequencies for number of hospitalizations and as average annual expenses expressed in dollars (US$) in relation to cost data. RESULTS: there was a reduction in hospitalization expenses after implementing supplementary PHC (p=0.01) and a decrease in the frequency of hospitalizations for the entire sample (p=0.006). There was a reduction in the frequency of consultations at the Emergency Room among frail older adults (p=0.011). CONCLUSIONS: there was a reduction in hospitalization costs and frequency of visits to the Emergency Room after supplementary PHC.

Factors Associated with Leg Ulcers in Adults with Sickle Cell Disease in Brazil.

OBJECTIVE: To define the prevalence of leg ulcers and identify the clinical and laboratory factors associated with leg ulcers in adult participants. METHODS: The authors conducted a cross-sectional study of 1,109 patients who were 18 years or older with SS or Sß0-thalassemia genotypes from a Brazilian cohort. Investigators assessed the prevalence of factors associated with leg ulcers from 2013 to 2017. RESULTS: The prevalence of leg ulcers was 21%. Increasing age (odds ratio [OR], 1.07; range, 1.06-1.09), male sex (OR, 2.03; range, 1.44-2.87), treatment with chronic transfusion therapy (OR, 1.88; range, 1.15-3.03), higher indirect bilirubin levels (OR, 1.48; range, 1.02-2.16), and low hemoglobin levels (OR, 2.17; range, 1.52-3.11) were associated with leg ulcers. Participants who self-reported as Black (OR, 6.75; range, 2.63-21.32), mixed (OR, 3.91; range, 1.55-12.20), and other/unknown (OR, 3.84; range, 1.04-15.24) were more likely to have leg ulcers compared with those who self-reported as White. CONCLUSIONS: The prevalence of leg ulcers in this Brazilian cohort was higher than the prevalence reported in developed countries. Known factors such as age and male sex were corroborated. The increased bilirubin level and decreased hemoglobin levels among participants with leg ulcers support the hypothesis that hemolysis is correlated with leg ulcer pathogenesis. Self-reported black skin color was an independent predictor of leg ulcers and warrants further study to understand the etiology and implications of this finding.

Epidemiological Profile of Patients with Infective Endocarditis at three Tertiary Centers in Brazil from 2003 to 2017

Abstract Background Infective endocarditis (IE) is a disease with high morbimortality and an increasing incidence. With improved diagnosis and treatment, a number of epidemiological changes have been reported over time. Objectives We sought to describe the epidemiological profile, mortality predictors, and analysis of a possible microbiological transition in patients admitted to three tertiary centers in Brazil. Methods In this cross-sectional retrospective study, data from 211 patients with definite or probable IE were analyzed according to the modified Duke criteria between 2003 and 2017. The association between categorical variables was assessed using the chi-square or Fisher's exact test, and binary logistic models were built to investigate mortality. We considered p <0.05 statistically significant. Results The median age of the sample was 48 (33-59) years old, 70.6% were men, and the most prevalent pathogen was Staphylococcus spp. (19%). Mortality was 22.3%, with increasing age being the leading risk factor for death (p = 0.028). Regarding the location of the disease, native valves were the most affected site, with the aortic valve being more affected in men than women (p = 0.017). The mean number of cases of Staphylococcus spp. (τ = 0.293, p = 0.148) and Streptococcus spp. (τ = -0.078, p = 0.727) has remained stable over the years. Conclusion No trend towards reduced or increased mortality was evident between 2003 and 2017. Although Staphylococcus spp. were the most prevalent pathogen, the expected epidemiological transition could not be observed.

Prevalence and Risk Factors for Human T-Cell Lymphotropic Virus (HTLV) in Blood Donors in Brazil-A 10-Year Study (2007-2016).

It is unknown whether HTLV-1/2 prevalence has been stable or changing with time in Brazil. We present a 10-year (2007-2016) analysis of HTLV-1/2 infection in first-time blood donors from four blood banks in Brazil. The Brazilian blood centers participating in this multicenter Recipient Epidemiology and Donor Evaluation Study (REDS) are located in Recife in the Northeast and in São Paulo, Rio de Janeiro and Belo Horizonte located in the Southeast of the country. A previous REDS study using the same database from 2007 to 2009 showed that the prevalence per 100,000 donors was 222 in Recife, 83 in Belo Horizonte and 101 in São Paulo. From 2007 to 2016, HTLV-1/2 prevalence was calculated by year, blood center and birth cohort. Covariates included age, gender, schooling, self-reported skin color and type of donation. From 1,092,174 first-blood donations, in the general analysis, HTLV-1/2 infection predominated in females, donors over 50 years of age, black skin color and less educated. The average prevalence was 228 per 100,000 donors in Recife, 222 in Rio de Janeiro, 104 in Belo Horizonte and 103 in São Paulo. In the 10-year analysis, HTLV-1/2 prevalence was stable, but a trend was observed toward an increase in HTLV-1/2 infection among younger people (p < 0.001), males (p = 0.049), those with white skin color (p < 0.001), and higher education (p = 0.014). Therefore, this 10-year surveillance of the infection showed stable HTLV-1/2 prevalence overall but a trend toward increased prevalence among the younger and more educated donors despite Brazilian policies to control sexually transmitted infections being in place for more than 10 years.

Downregulation of CD73 on CD4+ T cells from patients with chronic Chikungunya infection.

Chikungunya is an important mosquito-borne disease caused by the arthritogenic chikungunya virus, characterized by sporadic outbreaks all around the world. Although CD4+ T cells seem to have an important role in the pathogenesis of chikungunya, the mechanisms involved in this process are not yet fully elucidated. The ectoenzymes CD39 and CD73, also expressed by CD4 T lymphocytes, are involved in the hydrolysis of pro-inflammatory extracellular ATP and generation of immunosuppressive adenosine and seem to be modulated in some arthritogenic pathologies. However, their involvement in Chikungunya disease is unclear. Thus, using flow cytometry, we investigated peripheral CD4+ T cells from patients with acute and chronic chikungunya to assess the expression of ectonucleotidases CD39 and CD73 and coinhibitory receptors and production of cytokine and cytolytic granules. Patients in the acute phase displayed increased levels of PD-1, CTLA-4, IL-10, and IFN-γ compared to healthy individuals and patients in the chronic phase. Moreover, during chronic Chikungunya, analyses of Mean Fluorescent Intensity (MFI) demonstrated a reduced density of LAP, Perforin and Granzyme B compared to the healthy control. Finally, reduced levels of the ectoenzymes CD39 and CD73 expression was found during the chronic phase suggesting a possible modulation of extracellular ATP and adenosine by CD4+ T cells that may be involved in the persistence of arthritogenic symptoms.

Regulatory T cells in acute and chronic human Chikungunya infection.

Chikungunya virus (CHIKV) infection generates strong immune responses that are associated with the disease pathophysiology. Regulatory T cells (Treg-cluster of differentiation (CD)-4+CD25highforkhead box P3 (FOXP3+)) are essential for the induction and maintenance of peripheral tolerance. Thus, they play key roles in determining the patient prognosis by preventing excessive immune responses via different suppression immune mechanisms. However, the regulatory mechanisms involved in human CHIKV infection are still poorly understood. Here, we characterize for the first time the Treg cell molecule-associated-mechanism during acute and chronic human Chikungunya disease. Here, we assessed the Treg cell population and molecule-associated mechanism in the peripheral blood samples of acute and chronic patients with Chikungunya. Our results indicate that CHIKV infection is associated with reduced frequency of Tregs, along with the impaired expression and production of Treg functional markers, including CD39, CD73, perforin, granzyme, programmed death 1 (PD-1), cytotoxic T lymphocyte antigen (CTLA)-4, and transforming growth factor (TGF)-ß. This observation suggests that Treg cells possess the poor regulatory capacity in both acute and chronic phases of the disease. Taken together, these data provide significant evidence that the imbalanced response of Treg cells plays an essential role in establishing the pathogenesis of Chikungunya.

Quando édipo encontra Lábdaco: Sobre o complexo de édipo entre um avô e uma neta à luz da psicanálise vincular / When oedipus meets Lábdaco: About the oedipus complex between a grandfather and a granddaughter in the light of Links Psychoanalysis / Cuando edipo encuentra Lábdaco: Sobre el complejo de edipo entre un abuelo y una nieta a la luz de Psicoanálisis Vincular

O complexo de Édipo é até hoje um dos conceitos mais centrais no campo da psicanálise e se refere a uma dada situação familiar prototípica que supostamente atravessa todo sujeito no decorrer de seu desenvolvimento emocional. Tendo o conceito passado por diversas revisões, complementações e críticas ao longo do tempo, e, embora tenha perdido seu caráter universal, não ocorrendo necessariamente entre pai, mãe e criança, como acreditava Freud, ainda assim tem sua importância. Entretanto, são poucos os trabalhos que abordam outras dinâmicas relacionais na família, para além do relacionamento pais e filhos. Este artigo se propõe a contribuir para o estudo específico do vínculo entre avós e netos, por meio de um relato de caso bastante particular acerca de um complexo edípico envolvendo esse tipo de dupla. O aporte teórico da psicanálise vincular foi eleito por ser um referencial que enfatiza o âmbito intersubjetivo e o todo familiar, podendo, assim, melhor abarcar uma reflexão aprofundada sobre essa temática.

The Oedipus complex is to this day one of the most central concepts in the field of psychoanalysis and refers to a given prototypical family situation that supposedly crosses every subject in the course of his emotional development. Since the concept has undergone several revisions, complements and criticisms over time, and although it has lost its universal character, not necessarily occurring between father, mother and child, as Freud believed, it still has its importance. However, few studies deal with other relational dynamics in the family, in addition to the relationship between parents and children. This article proposes to contribute to the specific study of the bond between grandparents and grandchildren, through a very particular case report about an oedipal complex involving this type of pair. The theoretical contribution of the links psychoanalysis was chosen because it is a reference that emphasizes the intersubjective scope and the family, and, therefore, better to include a deep reflection on this theme.

Sin embargo, son pocos los trabajos que abordan otras dinámicas relacionales en la familia, además de la relación padres e hijos. Este artículo se propone contribuir al estudio específico del vínculo entre abuelos y nietos, por medio de un relato de caso bastante particular acerca de un complejo edípico envolviendo ese tipo de doble.

Trabalhando o vínculo, trabalhando no vínculo: considerações sobre o papel da transferência no atendimento de crianças e jovens que sofreram rupturas familiares / Working the bond, working in the bond: considerations about the role of transfer in the care of children and young people who have suffered family breaks / Trabajar el vínculo, trabajar en el vínculo: consideraciones sobre el papel de la transferencia en el cuidado de los niños y jóvenes que han sufrido descansos familiares

O objetivo deste trabalho é refletir acerca de situações de rupturas familiares, que geram consequências importantes para a formação do self, e sobre a possibilidade de elaboração frente a esperança produzida pela construção de novos vínculos. Quais as reverberações dessas rupturas familiares no processo de constituição da identidade e no desenrolar da própria transferência num atendimento de orientação psicanalítica? Numa tentativa de responder a essa pergunta, será destacado aqui o vínculo transferencial como promotor de uma potencialidade terapêutica.

The main objective of the present paper is, based on the psychoanalytic theory (specially Winnicott's considerations), to reflect about situations regarding the rupture of family links, which cause relevant consequences to the construction of the self of a child, and about the possibility of elaboration with the development of new links. Considering those ruptures, what are the reverberations in the process of identity constitution and, considering the analysis environment, in the outcome of the transference itself? To answer this question, it will be highlighted in the present paper the bond between analyst and patient as a promoter of a therapeutic potentiality.

El objetivo desto trabajo es refletir acerca de situaciones de rupturas familiares y las consecuencias que estas tienen en la formación del self, y acerca de la posibilidad de elaboración frente a la esperanza producida por la construcción de novos vinculos. ¿Quales son las reverberaciones de esas rupturas familiares en los procesos de constitución de la identidad y en el desenvolvimiento de la propia transferencia en un atendimiento de orientación psicoanalítica? En una tentativa de responder a essa pregunta, será destacado aqui el vínculo transferencial como promotor de una potencialidad terapeutica.

Enlightening clinical and therapeutic heterogeneity in thoracic actinomycosis: A review in bronchiectasis and non-bronchiectasis patients.

Actinomycosis is a rare chronic infection triggered by species of Actinomyces. Although thoracic involvement represents about 15% of human actinomycosis, its true incidence may be underestimated, not only because of its challenging diagnosis, but also because it can be treated unintentionally with antibiotics for other diseases. In this sense, this work aims at providing an up-to-date literature review on thoracic actinomycoses, with particular emphasis on presentation, diagnostic and therapeutic approaches, also paving upcoming clinical interventions from findings obtained of a presentation of a case series. Data discussed here clearly denote the rarity, non-specificity and heterogeneity of clinical presentations of the disease, reinforcing the need for individualized therapeutic approaches.

Phenotypical characterization of regulatory T cells in acute Zika infection.

Zika virus (ZIKV), alongside Dengue virus (DENV), Chikungunya virus (CHIKV), and Yellow Fever Virus (YFV) are prevalent arboviruses in the Americas. Each of these infections is associated with the development of associated disease immunopathology. Immunopathological processes are an outcome of counter-balancing impacts between effector and regulatory immune mechanisms. In this context, regulatory T cells (Tregs) are key in modulating the immune response and, therefore, in tissue damage control. However, to date, Treg phenotypes and mechanisms during acute infection of the ZIKV in humans have not been fully investigated. The main aim of this work was to characterize Tregs and their immunological profile related to cytokine production and molecules that are capable of controlling the exacerbated inflammatory profile in acute Zika infected patients. Using whole blood analyses of infected patients, an ex vivo phenotypical characterization of Tregs, circulating during acute Zika virus infection, was conducted by flow cytometry. We found that though there are no differences in absolute Treg frequency between infected and healthy control groups. However, pro-inflammatory cytokine up-regulation such as IFN-γ and LAP was observed in the acute disease. Furthermore, acute ZIKV patients expressed increased levels of CD39/CD73, perforin/granzyme B, PD-1, and CTLA-4, all markers involved in mechanisms used by Tregs to attempt to control strong inflammatory responses. Thus, the data indicates a potential contribution of Tregs during the inflammatory ZIKV infection response.

Predictors and reference equations for augmentation index, an arterial stiffness marker, in healthy children and adolescents.

OBJECTIVES: To investigate predictors and propose reference equations for the augmentation index normalized to 75 bpm heart rate (AIx@75) in healthy children and adolescents. METHODS: This was a cross-sectional, observational study involving 134 healthy children and adolescents aged 9 to 19 years old. Participants were categorized into child (n=53) and adolescent (n=81) groups, as well as into male (n=69) and female (n=65) groups. We evaluated AIx@75, vascular and hemodynamic parameters, anthropometric data, physical activity profile, and quality of life (Peds-QL4.0; physical, emotional, social and school domains). RESULTS: The predictors of AIx@75 in the whole sample were age, peripheral diastolic blood pressure (pDBP), mean arterial pressure, pulse pressure amplification (PPA), systolic volume (SV), cardiac index (CI), and pulse wave velocity (PWV; R2=80.47%). In the male group, the predictors of AIx@75 were SV, CI, total vascular resistence (TVR), and PWV (R2=78.56%), while in the female group, they were pDBP, PPA, SV, and PWV (R2=82.45%). In the children, they were pDBP, PPA, SV, and PWV (R2=79.17%), while in the adolescents, they were body mass index, pDBP, PPA, SV, TVR, and PWV (R2=81.57%). CONCLUSION: In the present study, we used a representative sample from Belo Horizonte to establish normality values of AIx@75. We also identified, for the first time, independent predictors of AIx@75 in healthy children and adolescents categorized by sex and age. Determining AIx@75 reference equations may facilitate the early diagnosis of preclinical atherosclerosis and allow an objective measure of the vascular effects of therapeutic interventions aimed at modifying cardiovascular risk factors.

Partial Pulpotomy with Mineral Trioxide Aggregate in Permanent Incisors with Complicated Crown Fracture: 5-Year Follow-Up.

Traumatic dental injuries are highly prevalent among children. This article describes a case report of a patient who has experienced dental trauma at 8 years old, which has led to enamel-dentine fracture with pulp exposure in the left central incisor and crown-root fracture with pulp exposure in the right central incisor. Partial pulpotomy was performed with the aim of maintaining the neurovascular bundle, thus allowing normal radicular formation. During follow-up 5 years later, teeth were asymptomatic and with no evidence of radiolucent lesions in radiographic examinations. This report demonstrates that traumatic fractures with pulp exposure can be treated effectively by the described technique.

The DNA Sensor AIM2 Protects against Streptozotocin-Induced Type 1 Diabetes by Regulating Intestinal Homeostasis via the IL-18 Pathway.

Pattern recognition receptors (PRRs), such as Nod2, Nlrp3, Tlr2, Trl4, and Tlr9, are directly involved in type 1 diabetes (T1D) susceptibility. However, the role of the cytosolic DNA sensor, AIM2, in T1D pathogenesis is still unknown. Here, we demonstrate that C57BL/6 mice lacking AIM2 (AIM2-/-) are prone to streptozotocin (STZ)-induced T1D, compared to WT C57BL/6 mice. The AIM2-/- mice phenotype is associated with a greater proinflammatory response in pancreatic tissues, alterations in gut microbiota and bacterial translocation to pancreatic lymph nodes (PLNs). These alterations are related to an increased intestinal permeability mediated by tight-junction disruption. Notably, AIM2-/- mice treated with broad-spectrum antibiotics (ABX) are protected from STZ-induced T1D and display a lower pancreatic proinflammatory response. Mechanistically, the AIM2 inflammasome is activated in vivo, leading to an IL-18 release in the ileum at 15 days after an STZ injection. IL-18 favors RegIIIγ production, thus mitigating gut microbiota alterations and reinforcing the intestinal barrier function. Together, our findings show a regulatory role of AIM2, mediated by IL-18, in shaping gut microbiota and reducing bacterial translocation and proinflammatory response against insulin-producing ß cells, which ultimately results in protection against T1D onset in an STZ-induced diabetes model.
