ABSTRACT

ABSTRACT Introduction: Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) patients are exposed to acute and chronic nephrotoxic events (drugs, hypotension, infections, and microangiopathy). The need for hemodialysis (HD) may be associated with high mortality rates. However, the risk factors and clinical impact of HD are poorly understood. Aim: To analyze survival and risk factors associated with HD in allo-HSCT Patients and methods: single-center cohort study 185 (34 HD cases versus 151 controls) consecutive adult allo-HSCT patients from 2007-2019. We performed univariate statistical analysis, then logistic regression and competing risk regression were used to multivariate analysis. Survival was analyzed by Kaplan-Meier and Cox proportional-hazards models. Results: The one-year HD cumulative incidence was 17.6%. Univariate analysis revealed that HD was significantly associated with male gender, age (p 0.056), haploidentical donor, grade II-IV acute GVHD, polymyxin B, amikacin, cidofovir, microangiopathy, septic shock (norepinephrine use) and steroid exposure. The median days of glycopeptides exposure (teicoplanin/vancomycin) was 16 (HD) versus 10 (no HD) (p 0.088). In multivariate analysis, we found: norepinephrine (hazard ratio, HR:3.3; 95% confidence interval, 95%CI:1.2-8.9; p 0.024), cidofovir drug (HR:11.0; 95%CI:4.6 - 26.0; p < 0.001), haploidentical HSCT (HR:1.94; 95%CI:0.81-4.65; p 0.14) and Age (HR:1.01; 95%CI: 0.99-1.03; p 0.18). The HD group had higher mortality rate (HR:6.68; 95% CI: 4.1-10.9; p < 0.001). Conclusion: HD was associated with decreased survival in allo-HSCT. Carefully use of nephrotoxic drugs and improving immune reconstitution could reduce severe infections (shock) and patients requiring cidofovir, which taken together may result in lower rates of HD, therefore improving survival.

ABSTRACT

ABSTRACT Objective To analyze the karyotype test and myeloid panel with next-generation sequencing findings in patients with myelofibrosis, and to compare transplant characteristics in patients referred for bone marrow transplantation. Methods Retrospective, single-center study with patients diagnosed with myelofibrosis treated at Hospital Israelita Albert Einstein between 2010 and 2020. Results A total of 104 patients with myelofibrosis were examined. Patients who had not been submitted to tests in our service were excluded. The final sample comprised 69 patients. Of these 69, 56 were submitted to karyotyping and 22 to myeloid panel with next-generation sequencing. Karyotype was normal in 60% of the patients and altered in 40%. The prevalence of high-risk molecular mutations was higher in patients referred for bone marrow transplantation (100% versus 50%). The median follow-up of transplant patients was 2.4 years and the overall survival at 2 years was 80% (95%CI: 62-100%). Conclusion The molecular analysis enables estimating the patient's risk and thus instituting more aggressive treatment such as bone marrow transplant for patients at higher risk, being a relevant tool to guide therapy. Given the significance of molecular analysis for therapeutic decision-making in myelofibrosis, collection and disclosure of data on the prevalence of cytogenetic changes and findings of next-generation sequencing in affected patients is important.

ABSTRACT

A fístula liquórica para o osso temporal constitui um evento raro que decorre da comunicação anormal entre o espaço subaracnóideo e as células da mastoide, permitindo que o líquido cefalorraquidiano flua para as porções pneumatizadas do osso temporal. Tem como consequência a hipotensão intracraniana espontânea, caracterizada por perda de líquor e pela manifestação clínica de cefaleia ortostática. Acredita-se que a hipotensão intracraniana espontânea crie condições hemodinâmicas favoráveis à ocorrência de trombose venosa cerebral, uma desordem potencialmente fatal e de difícil diagnóstico, visto a inespecificidade de sinais clínicos e sintomas. Dessa forma, é pertinente atentar para a possibilidade de trombose venosa cerebral em pacientes com fístulas liquóricas, especialmente quando houver mudança do padrão da cefaleia, que passa de ortostática a intensa e contínua.


Temporal bone cerebrospinal fluid fistula is a rare event that results from abnormal communication between the subarachnoid space and the mastoid cells, allowing the cerebrospinal fluid to flow into the pneumatized portions of the temporal bone. It leads to spontaneous intracranial hypotension, characterized by loss of cerebrospinal fluid and orthostatic headache as a clinical manifestation. Spontaneous intracranial hypotension is believed to create favorable hemodynamic conditions to the occurrence of cerebral venous thrombosis, a potentially fatal disorder of difficult diagnosis given the nonspecific clinical signs and symptoms. Therefore, it is pertinent to consider the possibility of cerebral venous thrombosis in patients with cerebrospinal fluid fistulas, especially when there is a modification in the headache pattern from orthostatic to intense and continuous pain.

ABSTRACT

Schwannomas are the fourth most common primary neoplasms affecting the brain and cranial nerves. Central lesions commonly arise from sensory nerve roots, and a common intracranial site is the vestibular branch of the 8th nerve (>85%). We present the case report of a patient who has a schwannoma extending from the pterygopalatine fossa to the orbit, complaining about facial pain in the trajectory of the trigeminal ophthalmic branch. Schwannomas represent 1 to 2% of all neoplasms of the orbit, and trigeminal schwannomas are extremely rare, accounting for less than 0.5% of all intracranial tumors.

ABSTRACT

ABSTRACT The novel coronavirus has swept across the world in 2020 and ushered a new era. In the current scenario, it is not clear how patients with myeloproliferative neoplasms (including chronic myelogenous leukemia) should be managed, considering the risk of therapy, the need for social distancing and the risk of untimely therapy discontinuation of delay. This guideline aims to give providers a sense of direction in order to better take care of patients and prioritize care.

ABSTRACT

ABSTRACT Acute myeloid leukemia is a hematopoietic stem cell neoplastic disease associated with high morbidity and mortality. The presence of FLT3 internal tandem duplication mutations leads to high rates of relapse and decreased overall survival. Patients with FLT3 internal tandem duplication are normally treated with hematopoietic stem cell transplantation in first complete remission. Nevertheless, the incidence of post-transplant relapse is considerable in this group of patients, and the management of this clinical condition is challenging. The report describes the outcomes of patients with FLT3 internal tandem duplication positive acute myeloid leukemia who relapsed after allogeneic hematopoietic stem cell transplantation and were treated with the combination of re-induction chemotherapy, donor lymphocyte infusion, sorafenib and azacitidine. Three cases are described and all patients achieved prolonged complete remission with the combined therapy. The combination of induction chemotherapy followed by donor lymphocyte infusion, and the maintenance with azacitidine and sorafenib can be effective approaches in the treatment of post-hematopoietic stem cell transplant and relapsed FLT3 internal tandem duplication positive acute myeloid leukemia patients. This strategy should be further explored in the context of clinical trials.


RESUMO A leucemia mieloide aguda é uma doença neoplásica de células-tronco hematopoiéticas com alta morbimortalidade. A presença de mutações de duplicação em tandem de FLT3 leva a altas taxas de recorrência e a menor sobrevida global. Os pacientes com duplicação em tandem de FLT3 são normalmente tratados com transplante de células-tronco hematopoiéticas na primeira remissão completa. No entanto, a incidência de recidiva pós-transplante é considerável neste grupo de pacientes, e a conduta, nestes casos, é um desafio. O relato descreve os resultados do tratamento de pacientes com leucemia mieloide aguda positiva e duplicação em tandem de FLT3 que recidivaram depois do transplante alogênico de células-tronco hematopoiéticas e que foram tratados com combinação de quimioterapia de reindução, infusão de linfócitos de doador, sorafenib e azacitidina. São descritos três casos, e todos os pacientes apresentaram remissão completa prolongada com a terapia combinada. A combinação de quimioterapia de indução, seguida de infusão de linfócitos do doador, e a manutenção com azacitidina e sorafenib podem ser abordagens eficazes no tratamento da recorrência pós-transplante em pacientes com leucemia mieloide aguda e duplicação em tandem de FLT3. Essa estratégia deve ser mais explorada no contexto de ensaios clínicos.

ABSTRACT

The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the left axilla. An ultrasound guided fine needle biopsy of this lymph node identified by I-131 SPECT/CT and FDG-F-18 PET/CT revealed lymphoma cells and was negative for thyroid tissue and thyroglobulin content. The sequential blood counts done routinely after radiation treatment showed a marked fall until return to normal values of leucocytes and lymphocytes (absolute and relative), which were still normal in the last control 19 months after the radioiodine administration. Chest computed tomography showed a decrease in size of axillary and para-aortic lymph nodes. By immunohistochemistry, cells of the lymphoid B lineage decreased from 52% before radioiodine therapy to 5% after the procedure. The authors speculate about a possible sodium iodide symporter expression by the cells of this lymphoma, similar to some other non-thyroid tumors, such as breast cancer cells.


Os autores relatam o caso de um paciente de 70 anos com leucemia linfóide crônica que apresentou subsequentemente um carcinoma papilífero da tireóide com metástases para linfonodos regionais. O paciente foi tratado com tireoidectomia total cirúrgica com exérese de linfonodos regionais e cervicais e radioiodoterapia (I-131). A pesquisa de corpo inteiro protocolar de controle 4 dias após a dose radioativa mostrou captação de I-131 em ambas as axilas e mesmo nas regiões inguinais. PET/CT mostrou discreta captação de FDG-F-18 em um linfonodo da axila esquerda. A biópsia por agulha fina guiada por ultrassom deste linfonodo identificado por SPECT/CT com I-131 e PET/CT com FDG-F-18 revelou células linfomatosas e foi negativa para tecido tireoidiano e conteúdo de tireoglobulina. Os hemogramas sequenciais feitos rotineiramente após tratamento com radiações mostraram uma acentuada queda até retorno aos valores normais de leucócitos e de linfócitos (absolutos e relativos), que continuavam normais no último controle 19 meses após a administração do radioiodo. Tomografia computadorizada de tórax mostrou uma redução em tamanho de linfonodos axilares e para-aorticos. Por imunohistoquímica, as células da linhagem linfoide B decresceram de 52% antes da radioiodoterapia para 5% depois do procedimento. Os autores conjeturam sobre uma possível expressão de symporter de iodeto de sódio pelas células deste linfoma, à semelhança de outros tumores não tireoidianos, tais como células de câncer da mama.

ABSTRACT

As tonsilas palatinas e faríngea são órgãos linfoides imunologicamente reativos, que manifestam anticorpos específicos e atividade de células B e T em resposta a uma variedade de antígenos, desempenhando funções de imunidade humoral e celular. Os possíveis efeitos imunológicos da adenotonsilectomia ainda permanecem controversos. OBJETIVO: O propósito desse estudo foi investigar o impacto da tonsilectomia na imunidade celular e humoral em crianças a curto e longo prazo. MÉTODO: Desenho do estudo: longitudinal prospectivo. Foram incluídas 29 crianças com indicação de adenotonsilectomia por hipertrofia adenoamigdaliana. IgA, IgM e IgG séricas e contagem de linfócitos foram analisados em 3 períodos: antes, 1 a 2 meses (curto prazo) e 12 a 14 meses (longo prazo) após o procedimento cirúrgico. RESULTADOS: Houve aumento estatisticamente significante de linfócitos TCD4+ a curto prazo após adenotonsilectomia. Os valores de IgA e IgG apresentaram diminuição significante a longo prazo, mas permaneceram dentro dos parâmetros de normalidade para a faixa etária. CONCLUSÃO: Os resultados do presente estudo indicam que a adenotonsilectomia, tanto a curto como a longo prazo, não apresenta repercussão negativa sobre a imunidade celular e humoral das crianças submetidas a este procedimento.


Palatine and pharyngeal tonsils are immune reactive lymphoid organs that manifest specific antibodies and B/T-cell activity to respond to a variety of antigens. They perform humoral and cellular immune functions. The possible effects of adenotonsillectomy upon the immune system remain controversial. OBJECTIVE: To study the short and long-term impacts of tonsillectomy upon the cellular and humoral immunity of children. METHOD: This longitudinal prospective study included 29 children referred to adenotonsillectomy for adenotonsillar hypertrophy. Serum IgA, IgM, and IgG and lymphocyte counts were analyzed at three points in time: before surgery, 1-2 months after surgery (short term), and 12-14 months after surgery (long term). RESULTS: TCD4+ cell counts were significantly increased shortly after surgery. IgA and IgG values were significantly reduced in the long run, but were within normal ranges for this age group. CONCLUSION: This study indicated that adenotonsillectomy does not pose negative short or long term impacts upon the cellular and humoral immunity of children submitted to the procedure.

ABSTRACT

Myeloproliferative neoplasms are clonal diseases of hematopoietic stem cells characterized by myeloid hyperplasia and increased risk of developing acute myeloid leukemia. Myeloproliferative neoplasms are caused, as any other malignancy, by genetic defects that culminate in the neoplastic phenotype. In the past six years, since the identification of JAK2V617F, we have experienced a substantial increase in our knowledge about the genetic mechanisms involved in the genesis of myeloproliferative neoplasms. Mutations described in several genes have revealed a considerable degree of molecular homogeneity between different subtypes of myeloproliferative neoplasms. At the same time, the molecular differences between each subtype have become clearer. While mutations in several genes, such as JAK2, myeloproliferative leukemia (MPL) and LNK have been validated in functional assays or animal models as causative mutations, the roles of other recurring mutations in the development of disease, such as TET2 and ASXL1 remain to be elucidated. In this review we will examine the most prevalent recurring gene mutations found in myeloproliferative neoplasms and their molecular consequences.

ABSTRACT

Objective: To identify how the Brazilian hematology centers treated and diagnosed cases of acute myeloid leukemia in 2009. Methods: An epidemiological observational multicenter study of 11 listed Brazilian centers that treat acute myeloid leukemia and perform bone marrow transplantation. Data were collected from clinical charts of patients with acute myeloid leukemia treated at the said centers between 2005 and 2009. The availability for immunophenotyping and cytogenetic tests was assessed. Results:During 2009, a total of 345 new cases of acute myeloid leukemia were diagnosed. Differences were noted in the tests performed between patients who initiated treatment at the center and those referred for treatment. Of the participating centers, 72% conducted some type of molecular study in acute myeloid leukemia upon diagnosis. Conclusion: Treatment for acute myeloid leukemia in Brazil shows significantly inferior results when compared to other centers worldwide.

ABSTRACT

Objective: To analyze the outcome of patients treated with gemtuzumab ozogamycin combined with conventional therapy treated at Hospital Israelita Albert Einstein. Methods: 14 patients who had high risk features (secondary leukemia, unfavorable cytogenetics, and refractory disease) were treated with gemtuzumab ozogamycincombined with conventional therapy and their outcome was analysed by reviewing their medical records. Results: Overall response rate was 58%, with 43% achieving complete response, with a median followup of 11 months, event-free survival was 3 months. Eleven patients died, 6 of them due to refractory acute myeloid leukemia. Only four patients presented with grade 3 to 4 toxicities and only one patient had sinusoidal obstruction syndrome after bone marrow transplant. Conclusion: gemtuzumab ozogamycin combined with chemotherapy is a feasible treatment regimen in acute myeloid leukemia patients. However, further studies are necessary to clarify which subgroup of patients may benefit from this treatment.


Objetivo: Analisar a evolução de pacientes tratados com gemtuzumabe ozogamicina combinado à terapêutica convencional no Hospital Israelita Albert Einstein. Métodos: 14 pacientes que tinham alto risco (leucemia secundária, citogenética desfavorávele doença refratária) foram tratados com gentuzumabe ozogamicina associado à terapêutica convencional, e sua evolução foi analisada por meio de seus prontuários médicos. Resultados: A taxa total de resposta foi de 58%, com 43% chegando a resposta completa, em acompanhamento médio de 11 meses, e três meses com intervalo de sobrevivência livre. Foram a óbito 11 pacientes, 6 deles por leucemia mieloide aguda. Somente quatro pacientes apresentaram graus 3 a 4 de toxicidade e apenas um paciente teve síndrome de obstrução sinusoidal após transplante de medula. Conclusão: Gemtuzumabe ozogamicina associado à terapêutica quimioterápica convencional éum tratamento factível em pacientes com leucemia mieloide aguda. Contudo, novos estudos são necessários para esclarecer qual o subgrupo de pacientes que pode se beneficiar desse tratamento.

ABSTRACT

O azanucleosídeo decitabina é aprovado para tratamento de pacientes com síndrome mielodisplásica de alto risco. Decitabina é droga relativamente bem tolerada quando comparada a esquemas de quimioterapia intensiva empregados em neoplasias mieloides, porém apresenta uma série de efeitos adversos, no qual se destaca a mielossupressão. A mielossupressão com decitabina depende do esquema posológico utilizado e tende a ser mais intensa nos primeiros ciclos de tratamento. Outros efeitos adversos de importância incluem mucosite, diarreia e hepatotoxicidade. Um conhecimento aprofundado sobre a toxicidade da decitabina e as melhores estratégias para seu manejo são necessários para se maximizar o benefício obtido com essa droga no tratamento da síndrome mielodisplásica.

ABSTRACT

Introdução e objetivos: Endoscópios são equipamentos utilizados com sucesso em diversos procedimentos de várias especialidades médicas. Entretanto, na área da otologia, mesmo com a incorporação dos endoscópios em procedimentos conjuntos com microscópio, os procedimentos puramente assistidos por endoscopia ainda são muito limitados. Nosso trabalho tem como objetivos demonstrar os procedimentos otológicos puramente endoscópicos realizados em nosso serviço e apresentar nossos resultados preliminares. Métodos: De outubro de 2007 até junho de 2009 fizemos revisão de cinco pacientes, quatro do sexo masculino e um feminino, com idades variando entre 7 e 54 anos de idade, selecionados para a realização de procedimentos otológicos puramente endoscópicos. Desenho do estudo: Retrospectivo. Resultados: Todos os pacientes apresentaram melhora da sintomatologia e correções das alterações em exame físico pré-operatório após a realização do procedimento endoscópico. Não houve complicações. Conclusões: A realização de procedimentos puramente endoscópicos em cirurgias otológicas é possível e pode apresentar algumas vantagens em relação ao uso de microscópios, dependendo principalmente do tipo e extensão de doença apresentada. Apresentamos nossa casuística, mostrando nossos resultados preliminares. Entretanto estudos com maior número de procedimentos são necessários para uma completa desmistificação destes instrumentos, que podem ser bastante úteis também na otologia.

ABSTRACT

Os distúrbios respiratórios do sono são doenças altamente prevalentes com grande impacto na qualidade de vida dos pacientes. Em grande parte dos casos não podemos estabelecer o diagnóstico e a gravidade do caso, baseando-nos apenas nos achados clínicos. Dessa forma torna-se imperativo a complementação diagnóstica com a polissonografia. O diagnóstico preciso permite um melhor planejamento terapêutico, elevando o sucesso do tratamento. Este artigo se propõe a revisar aspectos clínicos e diagnósticos dos distúrbios respiratórios do sono com ênfase na interpretação da polissonografia.

ABSTRACT

INTRODUCTION AND AIMS: the Internet is the world's fastest growing source of health related information. Parents and guardians are increasingly turning to the Internet for information about their children's medical conditions and treatments. This paper has the following objectives 1) determine the prevalence of web searches for medical information performed by parents/guardians of children undergoing ENT surgery in a private hospital of Sao Paulo, Brazil. 2) assess whether the gathered information influenced the parents/guardians' decision on the treatment/surgery. METHOD: questionnaire voluntarily responded by 132 parents/guardians of children submitted to ENT surgery in a private hospital in Sao Paulo, Brazil. CONCLUSIONS: 117 parents/guardians (90 percent) used the Internet to search for information on the disease and surgical treatment of the children. Only 12 parents/guardians (10 percent) discussed the information with the physician assigned to perform the surgical procedure. 91 parents/guardians (78 percent) said that the information had impact upon the decision to have surgery performed on their children.

Nosso trabalho tem por objetivos: 1) determinar a prevalência de procura sobre informações médicas na Internet por pais/responsáveis de crianças submetidas a cirurgias otorrinolaringológicas em hospital privado de São Paulo, Brasil. 2) avaliar se estas informações influenciaram os pais/responsáveis quanto à decisão médica. MÉTODO: Questionário respondido voluntariamente por 132 pais/responsáveis de crianças submetidas a cirurgias otorrinolaringológicas em hospital privado de São Paulo, Brasil. CONCLUSÕES: 117 pais (90 por cento) utilizaram a Internet para procurar informações sobre a doença e tratamento cirúrgico dos filhos. Somente 12 parentes (10 por cento) discutiram as informações adquiridas com o médico que realizou o procedimento cirúrgico. Entretanto, 91 (78 por cento) afirmaram que as informações influenciaram as decisões sobre os procedimentos a serem realizados em filhos/dependentes. Otorrinolaringologistas devem estar conscientes do crescente uso da Internet como fonte de informações médicas e do conteúdo de páginas específicas com informações confiáveis e de fácil acesso para direcionarem pacientes, além de discutirem estas informações.

ABSTRACT

Introdução: Doenças sinusais afetam milhões de pessoas anualmente. Na maioria dos pacientes o tratamento clínico é eficaz, mas em casos de falha desta terapêutica a cirurgia endoscópica funcional é o atual método de escolha para tratamento cirúrgico. O objetivo da cirurgia endoscópica funcional é a aumentar a ventilação e drenagem dos seios paranasais envolvidos permitindo o retorno do funcionamento adequado dos movimentos mucociliares da mucosa nasal. Entretanto este método ainda apresenta algumas limitações, principalmente porque remove mucosa nasal e tecido ósseo, o que pode levar à alterações fisiológicas da mucosa nasossinusal e fibrose cicatricial. Muitos destes poderiam ser beneficiados com métodos menos invasivos, com maior preservação de mucosa nasal. A partir de 2006, um procedimento ainda menos invasivo ganhou destaque em nossa especialidade: a dilatação por balões dos óstios dos seios paranasais. Objetivo: Este artigo tem por objetivos: definir o conceito de sinuplastia, mecanismo de ação e apresentar o material necessário para realização de procedimentos; descrever as técnicas utilizadas com o equipamento em modelo simulador de cirurgia endoscópica nasossinusal e revisar na literatura atual, as indicações, complicações, resultados e seguimento de pacientes submetidos a este procedimento. A sinuplastia com balão é segura e parece ser efetiva na melhoria da qualidade de vida de pacientes não responsivos aos tratamentos clínicos convencionais. Novas aplicações e indicações para estes equipamentos devem ser trazidos e pesquisados.


Introduction: Sinus diseases affect millions of people annually. Clinical treatment is effective in most patients, but in case of failure of this therapy the functional endoscopic surgery is currently the treatment choice for surgical treatment. The objective of the functional endoscopic surgery is to increase the aeration and drainage of the involved paranasal sinuses, which allows for the adequate functioning of the nasal mucosa mucociliary clearance. However, this method still has some limitations, mainly because it removes the nasal mucosa and bone tissue, and it may lead to physiologic alterations of the nasosinusal mucosa and cicatricial fibrosis. Many of these patients could be benefited from less invasive methods, with larger nasal mucosa preservation. Since 2006, an even less invasive procedure was remarked in our specialty: the balloon dilatation of the paranasal sinus ostia. Objective: The objective of this article is to define the concept of sinuplasty, its action mechanism, and present the necessary material for the procedures performance; to describe the techniques with the equipment in a nasosinusal endoscopic surgery simulator model and review the current literature about the indications, complications, results, and follow-up of patients submitted to this procedure. Balloon sinuplasty is safe and appears to be effective in the improvement of the quality of life of patients not responsive to conventional clinical therapy. New applications and indications for this equipment should be described and researched.
