1. Pre-analytical parameters associated with unsuccessful karyotyping in myeloid neoplasm: a study of 421 samples
Cytogenetics is essential in myeloid neoplasms (MN) and pre-analytical variables are important for karyotyping. We assessed the relationship between pre-analytical variables (time from collection to sample processing, material type, sample cellularity, and diagnosis) and failures of karyotyping. Bone marrow (BM, n=352) and peripheral blood (PB, n=69) samples

2. Maxillomandibular giant osteosclerotic lesions
Abstract Giant Osteosclerotic Lesions (GOLs) are a group of rarely reported intraosseous lesions. Their precise diagnosis is important since they can be confused with malignant neoplasms. Objective This retrospective study aimed to record and analyze the clinical and radiographic Giant Osteosclerotic Lesions (GOLs) detected in the maxillomandibular area of

3. Evaluation of the Prevalence of Maxillary Sinuses Abnormalities through Spiral Computed Tomography (CT)
Abstract Introduction Maxillary sinus disease is common and numerous disorders can affect this anatomical area. Abnormalities can be classified as: non-neoplastic, neoplastic benign, and neoplastic malignant. Objective Evaluate through CT the prevalence of diseases in maxillary sinuses, using the Radiology Department’s database of a hospital in São Pa

4. Secondary myeloid neoplasms: bone marrow cytogenetic and histological features may be relevant to prognosis
Abstract Background: Secondary myeloid neoplasms comprise a group of diseases arising after chemotherapy, radiation, immunosuppressive therapy or from aplastic anemia. Few studies have addressed prognostic factors in these neoplasms. Method: Forty-two patients diagnosed from 1987 to 2008 with secondary myeloid neoplasms were retrospectively evaluated conce

6. Subungual squamous cell carcinoma
Abstract Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or vira

7. The role of magnetic resonance imaging in the evaluation of transfusional iron overload in myelodysplastic syndromes
Myelodysplastic syndromes represent a group of heterogeneous hematopoietic neoplasms derived from an abnormal multipotent progenitor cell, characterized by a hyperproliferative bone marrow, dysplasia of the cellular hemopoietic elements and ineffective erythropoiesis. Anemia is a common finding in myelodysplastic syndrome patients, and blood transfusions are

8. Oral cancer after prolonged immunosuppression for multiorgan chronic graft-versus-host disease
Long-term survivors of hematopoietic stem cell transplantation are recognized as a risk group for malignization. Malignant oral neoplasms are increasingly being reported in the literature as a consequence of lesions of chronic graft-versus-host disease, and prolonged multidrug treatment to control its manifestations. This report describes a 43-year-old patie

9. Karyotypic and fluorescent in-situ hybridization study of the centromere of chromosome 7 in secondary myeloid neoplasms
BACKGROUND: Secondary myeloid neoplasms comprise a group of secondary diseases following exposure to myelotoxic agents or due to congenital diseases. The improvement of anticancer agents and immunosuppressive drugs seem to be associated with an increased incidence of secondary myeloid neoplasms. Karyotyping of bone marrow is essential for diagnosis and progn

10. Análise de glicosaminoglicanos e proteoglicanos em linhagens tumorais de próstata / Analysis of glycosaminoglycans and proteoglycans in prostate cancer cell lines
Proteoglycans (PG) are cell surface, extracellular matrix and citoplasmatic granule macromolecules, that play an important role in cellcell and cell-matrix interactions. Several studies indicated that significant changes in PG content occur in the tumor stroma of epithelial neoplasms and that these alterations influence tumor growth and invasion. In this stu

11. Estudo morfológico e por citogenética da medula óssea de portadores de síndrome mielodisplásica secundária no Serviço de Hematologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo / Morphological and cytogenetic bone marrow studies in patients with secondary myelodysplastic syndrome diagnosed at Department of Hematology of Clinical Hospital of São Paulo Medical School
As Síndromes mielodisplásicas (SMD) são doenças clonais da célula progenitora hematopoética, cursando com citopenias, medula óssea displástica e tendência à evolução para leucemia. As SMD secundárias estão associadas a fatores de risco como doenças congênitas (Anemia de Fanconi), doenças hematológicas adquiridas (aplasia medular, HPN), expo

12. Comparison of different severity score used in an oncologic pediatric intensive care unit / Comparação dos diferentes escores de gravidade utilizados em unidade de terapia intensiva pediátrica oncológica
Introduction: Although cancer is responsible for more deaths in children older than 1 year of age than any other disease, outcomes are improving. Improvements in survival rates and quality of life have been achieved due to early diagnosis, as well as aggressive therapies (chemotherapy, radiotherapy, surgery, bone marrow transplantation, and supportive measur
