Genomic variations in patients with myelodysplastic syndrome and karyotypes without numerical or structural changes.

Myelodysplastic syndrome (MDS) is an onco-hematologic disease with distinct levels of peripheral blood cytopenias, dysplasias in cell differentiation and various forms of chromosomal and cytogenomic alterations. In this study, the Chromosomal Microarray Analysis (CMA) was performed in patients with primary MDS without numerical and/or structural chromosomal alterations in karyotypes. A total of 17 patients was evaluated by GTG banding and eight patients showed no numerical and/or structural alterations.

Hepatitis B virus infection among oncohematologic disease patients in Central Brazil: prevalence, risk factors and immunization.

Introduction: Carriers of oncohematological diseases are at high risk for hepatitis B virus (HBV) infection.

Objective And Method: To investigate the epidemiology of HBV infection in Goiânia, Central Brazil, 322 individuals with oncohematological diseases (leukemias, Hodgkin lymphoma and non-Hodgkin lymphoma) were interviewed and blood samples were collected for the detection of serological markers of HBV-DNA by polymerase chain reaction (PCR). Medical records of participants were also reviewed.

Invasive fungal infection in patients with hematologic disorders in a Brazilian tertiary care hospital.

Introduction:: Invasive fungal infections (IFIs) are an important complication in immunocompromised individuals, particularly neutropenic patients with hematological malignancies. In this study, we aimed to verify the epidemiology and diagnosis of IFIs in patients with hematologic problems at a tertiary hospital in Goiânia-GO, Brazil.

Methods:: Data from 117 patients, involving 19 cases of IFIs, were collected.

Effect of low-level laser therapy on inflammatory mediator release during chemotherapy-induced oral mucositis: a randomized preliminary study.

Patients undergoing hematopoietic stem cell transplantation (HSCT) are submitted to a conditioning regimen of high-dose chemotherapy, with or without radiation therapy, which usually results in oral ulcerations and mucosal barrier breakdown. Oral mucositis (OM) is a common and debilitating toxicity side effect of autologous and allogeneic HSCT. The aim of this study was to evaluate the effect of low-level laser therapy (LLLT) on the severity of OM and inflammatory mediator (TNF-α, IL-6, IL-1β, IL-10, TGF-β, metalloproteinases, and growth factors) levels in saliva and blood of HSCT patients.

Embolization of intracranial aneurysms and sickle cell disease.

The association of intracranial aneurysms and sickle cell disease (SCD) has been described in the English-language literature. Treatment strategies have included angiography and craniotomy. However, with advancement of non-operative interventions, much controversy surrounds the treatment of these patients.
