Abstract Sickle cell intrahepatic cholestasis is a potentially fatal syndrome characterized by jaundice, painful hepatomegaly, and organ dysfunction. Two cases of sickle cell intrahepatic cholestasis associated with dengue fever were described. Endothelial damage/dysfunction is a mechanism involved in severe hepatobiliary complications related to sickle cell diseases. However, the reasons for the lack of increase in the admission of patients with sickle cell disease having severe acute hepatobiliary complications triggered by endothelial damage/dysfunction due to dengue fever remain unknown. This study describes the first association between sickle cell intrahepatic cholestasis and dengue fever.

ABSTRACT Objective analyze the meanings and perceptions of patients undergoing intrathecal chemotherapy about this treatment Method qualitative and descriptive study carried out with 13 participants attended at a Chemotherapy Center of a University Hospital in the interior of Minas Gerais, from 2015 to 2016, whose data were submitted to the analysis of the collective subject discourse. Approved by the Research Ethics Committee of the study development institution. Results the information obtained through the interviews was coded and five discourses emerged: lack of treatment, pain, anxiety, faith and hope. Conclusion intrathecal chemotherapy is unknown to patients undergoing treatment, causing anxiety, pain and adverse reactions that impair their quality of life. This creates mechanisms for coping with the disease through faith and hope.

RESUMEN Objetivo analizar los significados y las percepciones de los pacientes sometidos a quimioterapia intratecal sobre este tratamiento. Método estudio de enfoque cuantitativo y descriptivo desarrollado con 13 participantes atendidos en un Centro de Quimioterapia de un Hospital Universitario en el interior de Minas Gerais, entre 2015 y 2016, cuyos datos fueron sometidos al análisis del discurso del sujeto colectivo. Aprobado por el Comité de Ética en Investigación de la institución de desarrollo del estudio. Resultados la información obtenida a través de las entrevistas fue codificada y surgieron cinco discursos: falta de tratamiento, dolor, ansiedad, fe y Esperanza. Conclusión la quimioterapia intratecal es desconocida para los pacientes sometidos a tratamiento, lo que causa ansiedad, dolor y reacciones adversas que deterioran su calidad de vida. Esto crea mecanismos para hacer frente a la enfermedad a través de la fe y la esperanza.

RESUMO Objetivo analisar os significados e as percepções dos pacientes submetidos à quimioterapia intratecal sobre esse tratamento. Método estudo descritivo de abordagem quantiqualitativa, desenvolvida com 13 participantes atendidos em uma central de quimioterapia de um hospital universitário do interior de Minas Gerais, entre os anos de 2015 a 2016, cujos dados, obtidos por meio de entrevistas, foram submetidos à análise do discurso do sujeito coletivo. Aprovado pelo Comitê de Ética em Pesquisa da instituição campo do estudo. Resultados dos dados codificados emergiram cinco discursos: desconhecimento do tratamento, dor, ansiedade, fé e esperança. Conclusão a quimioterapia intratecal é desconhecida pelos pacientes em tratamento, causando ansiedade, dor e reações adversas as quais trazem prejuízo para a qualidade de vida desses indivíduos. Com isso criam-se mecanismos de enfrentamento da doença por meio da fé e da esperança.

Saprophytic fungi are being increasingly recognized as etiologic agents of mycoses in immunosuppressed patients. We report a case of subcutaneous infiltration by Aureobasidium pullulans, likely due to traumatic inoculation, in a neutropenic patient during chemotherapy for chronic lymphocytic leukemia. The patient was treated with amphotericin B deoxycholate but was subsequently switched to itraconazole, which improved the lesion. This case highlights the importance of considering unusual fungal infections in critically ill patients such as those who are immunosuppressed due to chemotherapy. Diagnostic techniques and effective antifungal therapy have improved the prognosis of these cases.

Aplastic anemia is a bone marrow failure syndrome characterized by peripheral cytopenias and hypocellular bone marrow. Although aplastic anemia is idiopathic in most cases, rheumatic diseases such as systemic lupus erythematosus are recognized as causes of aplastic anemia, with their possible etiological mechanisms being T and B lymphocyte dysfunction and pro-inflammatory cytokines and autoantibody production directed against bone marrow components. In the course of the human immunodeficiency virus infection/acquired immunodeficiency syndrome, the identification of autoantibodies and the occurrence of rheumatic events, in addition to the natural course of systemic lupus erythematosus which is modified by immune changes that are characteristic of human immunodeficiency virus infection/acquired immunodeficiency syndrome, make the diagnosis of systemic lupus erythematosus challenging. This study reports the case of a woman with acquired immunodeficiency syndrome treated with a highly active antiretroviral therapy, who had prolonged cytopenias and hypocellular bone marrow consistent with aplastic anemia. The clinical picture, high autoantibodies titers, and sustained remission of the patient's hematological status through immunosuppression supported the diagnosis of systemic lupus erythematosus-associated aplastic anemia. This is the first report of aplastic anemia concurrent with systemic lupus erythematosus and acquired immunodeficiency syndrome, providing additional evidence that immune dysfunction is a key part of the pathophysiological mechanism of aplastic anemia.

Myeloid sarcomas are extramedullary solid tumors composed of immature granulocytic precursor cells. In association with acute myeloid leukemia and other myeloproliferative disorders, they may arise concurrently with compromised bone marrow related to acute myeloid leukemia, as a relapsed presentation, or occur as the first manifestation. The testicles are considered to be an uncommon site for myeloid sarcomas. No therapeutic strategy has been defined as best but may include chemotherapy, radiotherapy and/or hematopoietic stem cell transplantation. This study reports the evolution of a patient with testicular myeloid sarcoma as the first manifestation of acute myeloid leukemia. The patient initially refused medical treatment and died five months after the clinical condition started.
