ABSTRACT Severe hemorrhage with necessity of allogeneic blood transfusion is common complication in intensive care unit and is associated with increased morbidity and mortality. Prompt recognition and treatment of bleeding causes becomes essential for the effective control of hemorrhage, rationalizing the use of allogeneic blood components, and in this way, preventing an occurrence of their potential adverse effects. Conventional coagulation tests such as prothrombin time and activated partial thromboplastin time present limitations in predicting bleeding and guiding transfusion therapy in […]

The use of vitamin D has increased in recent years because of its benefits, but as a result, intoxication cases have occurred more frequently. This report describes a patient who presented worsening of renal function and hypercalcemia. After investigation, vitamin D intoxication was confirmed and it was due to an error in compounding.

Objective:To describe the vertical clinical pharmacist service’s interventions in prevention of venous thromboembolism.Methods: This prospective study was done at a private hospital. From January to May 2012, the clinical pharmacist evaluated medical patients without prophylaxis for thromboembolism. If the patient fulfilled criteria for thromboembolism and did not have contraindications, the clinical pharmacist suggested inclusion of pharmacologic agents and/or mechanical methods for venous thromboembolism prevention. In addition, the appropriate dose, route of administration, duplicity and replacement of the drug were suggested.Results: […]

ABSTRACT Objective: To identify antiplatelet antibodies by flow cytometry (direct method) in patients with thrombocytopenia. Methods: Between January 1997 and March 2004 a total of 15100 patients were referred to the Centro de Hematologia de São Paulo for hematological investigation of several diagnoses (anemia, leukopenia, thrombocytopenia, coagulation abnormalities, adenomegaly, leukemia and others). Of those, 1057 were referred because of thrombocytopenia and were divided into two groups: Group Idiopathic thrombocytopenic purpura, with no identifiable cause; and Group Other thrombocytopenia, which included […]

ABSTRACT Objective: To demonstrate the advantages of correlating flow cytometry immunophenotyping with the pathology/ immunohistochemistry of lymph nodes or nodules in the diagnosis of lymphoproliferative diseases. Methods: A retrospective study was carried out of 157 biopsy or fine-needle aspiration lymph nodes/ nodule specimens taken from 142 patients, from 1999 and 2009. The specimens were simultaneously studied with fow cytometry and pathology at Hospital Israelita Albert Einstein. The specimens were prepared in hematoxylin/eosin, Giemsa, or monoclonal antibody stained slides for detecting […]

A 69-year-old Caucasian female was referred to the Imaging Department for investigation of fever of unknown origin (FUO), fatigue for seven months, and recent onset of atypical chest pain. Laboratory tests revealed elevation of serum C-reactive protein levels and erythrocyte sedimentation rate. Positron emission tomography with computed tomography fusion (PET-CT) with F18-fluorodeoxyglucose (FDG) was performed for the evaluation of FUO by excluding malignancy. The FDG images revealed markedly diffuse and circumferential increased uptake suggesting diffuse inflammatory process along the walls […]
