Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia in Children: A Retrospective Cohort Study at a Pediatric Oncology Center.

Background and objective Philadelphia chromosome-positive acute lymphoblastic leukemia (ALL Ph+) is quite rare among pediatric patients. Its management has undergone significant changes in the past few years, leading to some variability in how it is approached. At the Portuguese Oncology Institute of Porto (IPOP), a tertiary oncological center, the standard of care has been aligned with the guidelines proposed by the European intergroup study of post-induction treatment of ALL Ph+ (EsPhALL). In this study, we aimed to examine the experience and outcomes related to the treatment of pediatric patients with ALL Ph+ at IPOP. Methods This retrospective cohort study involved pediatric patients diagnosed with ALL Ph+ at IPOP between January 2008 and December 2022 and analyzed their outcomes. Results A total of 14 patients were included. IKFZ1 was altered in five patients (out of nine in whom it was searched). Five patients were treated according to EsPhALL 2004, which involved starting imatinib later in a discontinuous manner [resulting in both five-year overall survival (OS) and progression-free survival (PFS) of 60%]. The EsPhALL 2010 (preconizing a continuous imatinib regimen instead) was employed in three patients, with a five-year OS and PFS of 66.7%. All children mentioned above received cranial irradiation therapy (CRT). Finally, six were treated according to the EsPhALL 2015, which stopped including CRT in its backbone. The five-year OS was 100%, whereas every patient progressed with an increase in BCR::ABL1 levels greater than 1-log. Moreover, until 2015, all patients had been recommended to undergo allogeneic hematopoietic stem cell transplantation (alloHSCT). However, since 2015, alloHSCT has been exclusively reserved for relapsed/refractory (R/R) disease or poor responders with positive measurable residual disease (MRD). In total, alloHSCT was performed in nine patients. Conclusions Although initially associated with a poor prognosis, the ALL Ph+ paradigm is drastically shifting. Further studies will hopefully clarify the outcomes in this population and help understand the role of central nervous system (CNS) prophylaxis, alloHSCT, and MRD quantification.

Monitoring differences in the function of the autonomic nervous system in patients with chronic insomnia using a wearable device.

STUDY OBJECTIVES: to characterize possible differences in the function of the ANS in patients with chronic insomnia compared to a control group, using a wearable device, in order to determine whether those findings allow diagnosing this medical entity. METHODS: Thirty-two patients with chronic insomnia and nineteen patients without any sleep disorder, as a control group, were recruited prospectively. Both groups of patients underwent an in-patient night with simultaneous polysomnography and wearable device recording Empatica E4 a diverse array of physiological signals, including electrodermal activity, temperature, accelerometry, and photoplethysmography, providing a comprehensive resource for in-depth sleep analysis. RESULTS: In polysomnography, patients suffering from insomnia showed a significant decrease in sleep efficiency and total sleep time, prolonged sleep latency, and increased wakefulness after sleep onset. Accelerometry results were statistically significant differences in the three axis (x, y, z) just in stage N3, no differences were observed between both groups in REM sleep. The lowest temperature was reached in REM sleep in both groups. Peripheral temperature did not decrease during the different sleep phases compared to wakefulness in insomnia, unlike in the control group. Heart rate was higher in patients with insomnia than in controls during wakefulness and sleep stage. Heart rate variability was lower in stage N3 and higher in REM sleep compared to wakefulness in both groups. Sweating was significantly higher in patients with insomnia compared to the control group, as indicated by Skin Conductance Variability values and Sudomotor Nerve. CONCLUSIONS: Our study suggests that patients with insomnia have increased sympathetic activity during sleep, showing a higher heart rate. Temperature and sweating significantly influence the different sleep phases.

Acute Lymphoblastic Leukemia in a Pediatric Patient With Turnpenny-Fry Syndrome.

Turnpenny-Fry Syndrome (TPFS) is a rare genetic disorder characterized by a severe developmental delay and a distinctive facial gestalt. It is caused by mutations in the Polycomb Group Ring Finger Protein 2 (PCGF2) gene, which is also known to play a role in numerous tumor types. Up to date, there have been no published case reports of patients with TPFS and concomitant malignancies. The present case describes the clinical evaluation and follow-up of a male infant with severe global developmental delay (GDD) and a distinctive phenotype. At 4 years of age, clinical exome sequencing confirmed the diagnosis of TPFS. Posteriorly, at 5 years of age, the patient was also diagnosed with T-cell acute lymphoblastic leukemia (ALL). Given the scarce literature regarding this syndrome, the authors expect that this case report will provide valuable information that could improve the follow-up of patients with TPFS. Furthermore, this case highlights the necessity for the appropriate diagnosis of developmental disorders, to ensure adequate care, surveillance of comorbidities and proper genetic counselling.

Proteomic analysis of exosomes derived from human mature milk and colostrum of mothers with term, late preterm, or very preterm delivery.

The growth and development of the human brain is a long and complex process that requires a precise sequence of genetic and molecular events. This begins in the third week of gestation with the differentiation of neural progenitor cells and extends at least until late adolescence, possibly for life. One of the defects of this development is that we know very little about the signals that modulate this sequence of events. The first 3 years of life, during breastfeeding, is one of the critical periods in brain development. In these first years of life, it is believed that neurodevelopmental problems may be the molecular causes of mental disorders. Therefore, we herein propose a new hypothesis, according to which the chemical signals that could modulate this entire complex sequence of events appear in this early period, and the molecular level study of human breast milk and colostrum of mothers who give birth to children in different gestation periods could give us information on proteins influencing this process. In this work, we collected milk and colostrum samples (term, late preterm and moderate/very preterm) and exosomes were isolated. The samples of exosomes and complete milk from each fraction were analyzed by LC-ESI-MS/MS. In this work, we describe proteins in the different fractions of mature milk and colostrum of mothers with term, late preterm, or very preterm delivery, which could be involved in the regulation of the nervous system by their functions. We describe how they differ in different types of milk, paving the way for the investigation of possible new neuroregulatory pathways as possible candidates to modulate the nervous system.

Human Breast Milk microRNAs, Potential Players in the Regulation of Nervous System.

Human milk is the biological fluid with the highest exosome amount and is rich in microRNAs (miRNAs). These are key regulators of gene expression networks in both normal physiologic and disease contexts, miRNAs can influence many biological processes and have also shown promise as biomarkers for disease. One of the key aspects in the regeneration of the nervous system is that there are practically no molecules that can be used as potential drugs. In the first weeks of lactation, we know that human breast milk must contain the mechanisms to transmit molecular and biological information for brain development. For this reason, our objective is to identify new modulators of the nervous system that can be used to investigate neurodevelopmental functions based on miRNAs. To do this, we collected human breast milk samples according to the time of delivery and milk states: mature milk and colostrum at term; moderate and very preterm mature milk and colostrum; and late preterm mature milk. We extracted exosomes and miRNAs and realized the miRNA functional assays and target prediction. Our results demonstrate that miRNAs are abundant in human milk and likely play significant roles in neurodevelopment and normal function. We found 132 different miRNAs were identified across all samples. Sixty-nine miRNAs had significant differential expression after paired group comparison. These miRNAs are implicated in gene regulation of dopaminergic/glutamatergic synapses and neurotransmitter secretion and are related to the biological process that regulates neuron projection morphogenesis and synaptic vesicle transport. We observed differences according to the delivery time and with less clarity according to the milk type. Our data demonstrate that miRNAs are abundant in human milk and likely play significant roles in neurodevelopment and normal function.

Comunidade de Práticas em Terapia Ocupacional no Sistema Único de Assistência Social: articulando encontros e promovendo debates em terapia ocupacional social / Community of Practice in Occupational Therapy in the Brazilian Unified Social Assistance System: arranging meetings and promoting debates in social occupational therapy

Resumo Com o crescente número de terapeutas ocupacionais atuantes no Sistema Único de Assistência Social (SUAS), amplia-se a necessidade por processos formativos que desenvolvam criticamente a atuação profissional neste campo. A partir desta demanda formativa foi criado, em outubro de 2020, um projeto de extensão intitulado "Comunidade de práticas em terapia ocupacional no SUAS: articulação profissional e construção de estratégias", com o intuito de promover trocas de conhecimento e experiências entre terapeutas ocupacionais trabalhadoras em unidades socioassistenciais. Neste artigo se apresentam as possibilidades e os limites do trabalho no SUAS sob o ponto de vista de terapeutas ocupacionais que nele atuam e que foram participantes da Comunidade de Práticas, analisando se e como suas ações profissionais têm se relacionado com a fundamentação teórico-metodológica da terapia ocupacional social. Para isso, foi revisitado todo o material de registro produzido nos dois ciclos do projeto, efetivados de outubro de 2020 a julho de 2021. As informações extraídas das atas foram organizadas em um quadro que agrupou as temáticas encontradas. A análise dos dados revelou dois principais aspectos que possibilitam a correlação das ações das profissionais com a fundamentação teórico-metodológica da terapia ocupacional social, sendo: a necessária leitura acerca da indissociabilidade entre os fatores micro e macrossociais para o desenvolvimento do trabalho e a dimensão técnico-política da atuação terapêutico-ocupacional. Em ambos os debates a fundamentação teórico-metodológica da terapia ocupacional social foi e tem sido o fio condutor do processo, possibilitando uma leitura social e maior apropriação das finalidades técnico-profissionais no âmbito da assistência social.

Abstract With the growing number of occupational therapists working at the Unified Social Assistance System (SUAS) in Brazil, there has been an increasing need for education processes focusing on the critical development of professional practice in this field. From this education demand, a project was created in October 2020: "Communities of Practice in Occupational Therapy at SUAS: professional planning and construction of strategies" aiming to promote the exchange of knowledge and experiences between occupational therapists working in social assistance. This study aims to present the work possibilities and limits at SUAS from the point of view of occupational therapists who work at its units and who participated in the Community of Practice, analyzing whether and how their professional actions have been related to the social occupational therapy theoretical-methodological framework. To this end, all the recording material produced in the two project cycles from October 2020 to July 2021 was revisited. The collected information was organized in a table that grouped the themes found. Data analysis revealed two main aspects that allow the correlation of the professionals' actions with the social occupational therapy theoretical-methodological framework, namely, the necessary interpretation of the inseparability between micro- and macro-social factors for the development of work and the professional and political dimensions of the occupational-therapeutic actions. In both debates, the social occupational therapy theoretical-methodological framework has been the guiding thread of the process, enabling a social reading and a greater understanding of technical-professional purposes within the scope of social assistance.

Efficacy and Safety of Lithium Treatment in SARS-CoV-2 Infected Patients.

At the beginning of the pandemic, we observed that lithium carbonate had a positive effect on the recovery of severely ill patients with COVID-19. Lithium is able to inhibit the replication of several types of viruses, some of which are similar to the SARS-CoV-2 virus, increase the immune response and reduce inflammation by preventing or reducing the cytokine storm. Previously, we published an article with data from six patients with severe COVID-19 infection, where we proposed that lithium carbonate could be used as a potential treatment for COVID-19. Now, we set out to conduct a randomized clinical trial number EudraCT 2020-002008-37 to evaluate the efficacy and safety of lithium treatment in patients infected with severe SARS-CoV-2. We showed that lithium was able to reduce the number of days of hospital and intensive care unit admission as well as the risk of death, reduces inflammatory cytokine levels by preventing cytokine storms, and also reduced the long COVID syndromes. We propose that lithium carbonate can be used to reduce the severity of COVID-19.

Changes in the Brain Extracellular Matrix Composition in schizophrenia: A Pathophysiological Dysregulation and a Potential Therapeutic Target.

The brain extracellular matrix (ECM) is involved in crucial processes of neural support, neuronal and synaptic plasticity, extrasynaptic transmission, and neurotransmission. ECM is a tridimensional fibrillary meshwork composed of macromolecules that determine its bioactivity and give it unique characteristics. The characterization of the brain ECM is critical to understand its dynamic in SZ. Thus, a comparative study was developed with 71 patients with schizophrenia (SZ) and 70 healthy controls. Plasma of participants was analysed by label-free liquid chromatography-tandem mass spectrometry, and the results were validated using the classical western blot method. Lastly, immunostaining of post-mortem human brain tissue was performed to analyse the distribution of the brain ECM proteins by confocal microscopy. The analysis identified four proteins: fibronectin, lumican, nidogen-1, and secreted protein acidic and rich in cysteine (SPARC) as components of the brain ECM. Statistical significance was found for fibronectin (P = 0.0166), SPARC (P = 0.0003), lumican (P = 0.0012), and nidogen-1 (P < 0.0001) that were decreased in the SZ group. Fluorescence imaging of prefrontal cortex (PFC) sections revealed a lower expression of ECM proteins in SZ. Our study proposes a pathophysiological dysregulation of proteins of the brain ECM, whose abnormal composition leads to a progressive neuronal impairment and consequently to neurodegenerative processes due to lack of neurophysiological support and dysregulation of neuronal homeostasis. Moreover, the brain ECM and its components are potential pharmacological targets to develop new therapeutic approaches to treat SZ.

Experiências e percepções relacionadas ao gênero nas práticas profissionais de homens terapeutas ocupacionais / Experiences and perceptions related to gender in the professional practices of male occupational therapists

Resumo Introdução Estudos feministas contribuíram para o entendimento dos papéis de gênero atribuídos à mulher e ao homem enquanto processos socialmente construídos e não biologicamente determinados. No trabalho em saúde no Brasil, marcado pela predominância numérica de mulheres, a divisão sexual do trabalho é influenciada pela naturalização do cuidado como atributo feminino. Na terapia ocupacional, segundo o Conselho Regional da categoria, apenas 3,7% dos profissionais do Estado de São Paulo são homens, o que confere singularidade às relações entre gêneros na profissão. Objetivo Busca-se identificar e analisar experiências e percepções relacionadas ao gênero entre terapeutas ocupacionais autodeclarados homens. Método Estudo qualitativo de tipo exploratório, realizado por meio de entrevistas em profundidade com cinco terapeutas ocupacionais no município de São Paulo, SP, Brasil, posteriormente analisadas por meio de análise temática. Resultados Os entrevistados identificaram experiências que consideram ser privilégios de gênero não dissimulados, principalmente no que tange ao acesso ao emprego e à valorização profissional. Percebem que, no ambiente profissional, atuam estereótipos ligados ao padrão de comportamento atribuído ao gênero masculino, associando-o à força, autoridade e poder. Em se tratando de relações de cuidado com usuários, alguns participantes não percebem a presença de normas de gênero, o que parece convergente com a invisibilidade social desses processos. Conclusão Questões de gênero estão presentes nas vivências profissionais dos entrevistados, os quais, de modo geral, percebem-nas sob uma perspectiva crítica. Mostra-se relevante para a terapia ocupacional brasileira que novos estudos adensem reflexões e abordem distintas faces das relações de gênero na prática profissional.

Abstract Introduction Feminist studies have contributed to the understanding of the gender roles assigned to women and men as socially constructed and not biologically determined processes. In health work in Brazil, marked by the numerical predominance of women, the sexual division of labor is influenced by the naturalization of care as a female attribute. In occupational therapy, according to the Regional Council of the category, only 3.7% of professionals in the State of São Paulo are male, which gives uniqueness to gender relations in the profession. Objective We seek to identify and analyze gender-related experiences and perceptions among self-declared male occupational therapists. Method Qualitative exploratory study, carried out through in-depth interviews with five occupational therapists in the city of São Paulo, SP, Brazil, later analyzed through thematic analysis. Results Respondents identified experiences that they consider to be undisguised gender privileges, especially regarding access to employment and professional development. They perceive that, in the professional environment, there are stereotypes linked to the pattern of behavior attributed to the male gender, associating it with strength, authority and power. When it comes to care relationships with users, some participants do not perceive the presence of gender norms, which seems to converge with the social invisibility of these processes. Conclusion Gender issues are present in the professional experiences of the respondents, who, in general, perceive them from a critical perspective. It is relevant for Brazilian occupational therapy that new studies increase reflections and address different aspects of gender relations in professional practice.

The Role of the Second Extracellular Loop of Norepinephrine Transporter, Neurotrophin-3 and Tropomyosin Receptor Kinase C in T Cells: A Peripheral Biomarker in the Etiology of Schizophrenia.

The neurobiology of schizophrenia is multifactorial, comprising the dysregulation of several biochemical pathways and molecules. This research proposes a peripheral biomarker for schizophrenia that involves the second extracellular loop of norepinephrine transporter (NEText), the tropomyosin receptor kinase C (TrkC), and the neurotrophin-3 (NT-3) in T cells. The study of NEText, NT-3, and TrkC was performed in T cells and plasma extracted from peripheral blood of 54 patients with schizophrenia and 54 healthy controls. Levels of NT-3, TrkC, and NET were significantly lower in plasma and T cells of patients compared to healthy controls. Co-immunoprecipitation (co-IPs) showed protein interactions with Co-IP NEText-NT-3 and Co-IP NEText-TrkC. Computational modelling of protein-peptide docking by CABS-dock provided a medium-high accuracy model for NT-3-NEText (4.6935 Å) and TrkC-NEText (2.1365 Å). In summary, immunocomplexes reached statistical relevance in the T cells of the control group contrary to the results obtained with schizophrenia. The reduced expression of NT-3, TrkC, and NET, and the lack of molecular complexes in T cells of patients with schizophrenia may lead to a peripheral dysregulation of intracellular signaling pathways and an abnormal reuptake of norepinephrine (NE) by NET. This peripheral molecular biomarker underlying schizophrenia reinforces the role of neurotrophins, and noradrenergic and immune systems in the pathophysiology of schizophrenia.

Evaluation of the PBP2 transglycosylase region of Staphylococcus aureus as a target for immunotherapeutic approaches.

Infections caused by Staphylococcus aureus are increasingly prevalent, and treatment has become more difficult due to the emergence of strains that are resistant to multiple drugs, such as methicillin-resistant Staphylococcus aureus (MRSA). Penicillin-binding proteins (PBPs) are essential enzymes in peptidoglycan biosynthesis. Only found in bacteria, they are an excellent target for the development of bacterial control strategies. S. aureus has 4 PBPs, and only PBP2 has transglycosylation activity, making it a good model to evaluate whether the inactivation of the transglycosylase domain (PBP2t) could lead to bacterial death. (His6)-tagged PBP2t was purified from the E. coli cell lysate using Ni-charged resin, and ELISA and immunoblotting assays demonstrated that PBP2t is immunogenic. Flow cytometry analysis was performed to verify the binding of polyclonal antibodies to the bacterial cell surface. In order to verify the ability to provide protection, immunized mice were challenged with a sublethal dose of MRSA, and the bacterial loads in kidneys and spleen were evaluated. A reduction of 2-2.5 logs was seen in organs from immunized mice compared with the negative controls in two independent assays (p < 0.01). Our results demonstrate that the PBP2t is a promising target for the development of novel antimicrobial strategies, but further testing should be performed to validate the protection conferred by immunization with this protein.

Transformações na vida cotidiana de famílias que adotam crianças maiores: o ponto de vista de pais e mães / Transformations in daily life of families who adopt older children: the point of view of fathers and mothers

In Brazil, a large part of adopted children and adolescents were sheltered after a protective court order. In the adoption process, after the steps of gradual contact, children and parents start to live together permanently, when they experience the process of building a new daily life, in which activities and interactions already known undergo transformations. The study aimed to understand the deinstitutionalization process by adoption from the point of view of fathers and mothers who adopted children over two years. It was support by references that constitute the understanding of everyday life in the scope of occupational therapy, from a perspective that denaturalizes it, putting into view its complexity in the constellation of human interactions. It took place through the collection and analysis of interviews with adopting fathers and mothers. The results composed thematic axes gathering the perspectives of the parents, indicating that: a) their projections about future daily life were relevant in defining the profile of the children to be adopted; b) children's daily experiences in SAI were not properly presented to them prior to the phase of definitive coexistence; c) the process of building parenthood was essentially linked to the constitution of a common daily life, in family. It is essential to pay attention to the centrality of everyday life to build bonds and a stable socio-relational environments It is essential to pay attention to the centrality of everyday life to build bonds and stable socio-relational environments that are conducive to the development of children and adolescents

Os Sound Systems e os jovens das periferias de São Paulo: afirmando identidades e ampliando circuitos / The Sound Systems and the young people from the peripheries of São Paulo: affirming identities and expanding circuits

Introdução: Coletivos juvenis de periferias urbanas têm se constituído em torno de linguagens artísticas diversas e adquirido importância central na mediação das juventudes com a sociedade. Alguns se reúnem em torno dos Sound Systems de música reggae, que com a ocupação sonora de espaços públicos com caixas de som empilhadas e discos de vinil criam eventos culturais de rua. Objetivos: Conhecer os Sound Systems como atividade cultural, bem como suas repercussões no cotidiano de jovens que participam de coletivos que os promovem. Metodologia: Observações em eventos de Sound System e entrevistas com seletores de coletivos, interpretadas por análise temática. Resultados e discussão: Os coletivos se organizam na conjunção entre sonoridade, celebração e difusão de valores ligados à cultura negra. Para os seletores, o Sound System deve oferecer oportunidades de aprendizagem sobre a opressão histórica dos povos negros, bem como de fortalecimento da identidade e cultura negra. O pertencimento social, a elevação da autoestima e as oportunidades de aprendizagem pessoal foram mudanças associadas por eles à participação na cultura Sound System. Considerações finais: Os coletivos buscam ativamente produzir pontes entre o universo reggae jamaicano e as realidades dos jovens negros das periferias pobres da cidade de São Paulo, investindo no resgate da história e dos poderes agregadores da memória, da sonoridade, e de símbolos e mensagens da cultura reggae.

Introduction: Youth groups from urban peripheries have been constituted around diverse artistic languages and have acquired central importance in the mediation of youths with society. Some gather around the reggae music Sound Systems, which with the sound occupation of public spaces through stacked speakers and vinyl records create cultural street events. Objectives: To learn about the Sound Systems as a cultural activity as well as its repercussions on the daily lives of young people who participate in groups that promote them. Methodology: Observation in Sound System events and interviews with young people who work as selectors of these groups, interpreted by thematic analysis. Results and discussion: Sound System groups have been organized around the conjunction between sonority, celebration and dissemination of values linked to black culture. The selectors interviewed argue that the Sound System should provide opportunities to learn about the historical oppression of black people, as well as to strengthen of black identity and culture. Social belonging, increased self-esteem and opportunities for personal learning were changes they associated with participation in the Sound System culture. Final considerations: The groups actively seek to build bridges between the Jamaican reggae universe and the realities experienced by young black people from the disadvantaged peripheral areas of São Paulo city, investing in the rescue of history and the aggregating powers of memory, sound, symbols and messages from reggae culture.

The dentist as a child abuse informer: a case report

Introducition: Domestic violence against children interferes in their psychological development, leading to sequels that manifest and persist up to adulthood. Physical evidence of domestic violence is easily observed in the orofacial complex and eventually becomes detected by dentists. Case Report: We report the case of a 9-year-old victim of maltreatment who was diagnosed during dental treatment. The existence of physical injuries (a hematoma in the left orbit and burns on the left hand and in the lips) aroused the attention of the pediatric dentistry, whose brought the case to the responsible authorities. Custody of the child was granted to the grandmother by a court decision, which enabled the recovery of health and quality of life. Conclusion: Professionals must properly conduct cases through complaints in order to protect children from future occurrences.

Introdução: A violência doméstica contra as crianças interfere no seu desenvolvimento psicológico, levando a sequelas que se manifestam e persistem até a idade adulta. A evidência física da violência doméstica é facilmente observada no complexo orofacial e, eventualmente, é detectada pelos dentistas. Relato do Caso: Relatamos o caso de uma vítima de maus-tratos, de 9 anos de idade, que foi diagnosticada durante o tratamento odontológico. Um odontopediatra, durante as consultas de rotina, após identificar injúrias físicas (hematoma na órbita esquerda e queimaduras na mão esquerda e lábios), suspeitou tratar-se de maus tratos, levando o caso às autoridades responsáveis. A custódia da criança foi concedida à avó por uma decisão judicial, o que permitiu a recuperação da saúde e qualidade de vida. Conclusão: Os profissionais devem conduzir adequadamente os casos de abuso, a fim de proteger as crianças de ocorrências futuras.

A Rare Case of Spontaneous Remission and Relapse of a Primary Central Nervous System Lymphoma.

Primary central nervous system lymphoma remission after steroid treatment is a well-known phenomenon, but remission without any type of treatment is extremely rare. We present a rare case of spontaneous remission of a diffuse large B-cell lymphoma of the central nervous system as well as its subsequent reappearance in another location. The atypical presentation misled the neurosurgeons and neurologists, delaying diagnosis and treatment. The patient underwent brain biopsy after the relapse and started radiotherapy and chemotherapy with cytarabine + methotrexate + rituximab. As of 32 months after the diagnosis, the patient remained asymptomatic, with no focal neurological deficits and the disease in complete remission. A PubMed search of the literature up to June 2017 regarding spontaneous remission central nervous system lymphoma was also carried out.

É bem conhecida a remissão com corticoterapia dos linfomas primários do sistema nervoso central, mas a sua remissão sem qualquer tipo de tratamento é extremamente rara. Apresentamos um caso raro de uma remissão espontânea e posterior recidiva noutra localização de um linfoma difuso de grandes células B do sistema nervoso central. A apresentação atípica deste caso confundiu os neurocirurgiões e neurologistas, atrasando o diagnóstico e tratamento. A doente foi submetida a biópsia de uma das lesões cerebrais e, posteriormente, iniciou radioterapia e quimioterapia com citarabina + metotrexato + rituximab. Neste momento, 32 meses após o diagnóstico histológico, a doente encontra-se assintomática, sem défices neurológicos focais e com remissão completa da doença. Foi também efetuada uma pesquisa na PubMed até junho de 2017 sobre a remissão espontânea dos linfomas do sistema nervoso central.
