Models for releasing the lupus anticoagulant test
Conclusion: ICA aided in identifying the weak antibodies that were probably diluted in the mixing step. There is no gold standard test for the diagnosis of APS, and LAC detection still requires standardization of technique and interpretation.RESUMO Introdu ção: Trombofilia é a suscetibilidade à trombose, de natureza genética, adquirida ou mista. Entre as causas adquiridas, destaca-se a síndrome do anticorpo antifosfolípide (SAF) - doença autoimune caracterizada por anticorpos antifosfolípides, eventos trombóticos ou perda gestacional recorre nte. O diagnóstico laboratorial baseia-se na detecção do anticoagula...

Evaluation of relationship between hematocrit and lipid profile in adults
Conclusion: The relationship between hematocrit and lipid profile in all aspects of this study was more evident in women; nevertheless, the higher proportion of not recommended levels of HDL-C was shown in men. The reverse cholesterol transport probably plays an important role in the increase of cholesterol levels in blood in the presence of high hematocrit, by interaction of HDL-C and erythrocytes. Thus, further studies are necessary to elucidate these findings and to describe more aspects of the reverse cholesterol transport and its relationship with hematocrit and lipid profile.RESUMO Introdu ção e objetivo: Este est...

Analysis of BCL11A gene polymorphisms and hemolysis parameters in patients with sickle-cell disease
Conclusion: Polymorphisms in the rs7557939 region of the BCL11A gene appear to somehow interfere in the clinical setting of patients with SCD, suggesting relation with the concentration of MetHb and LDH. This study pioneered an investigation into the association of hemolysis biomarkers with BCL11A gene polymorphisms in SCD.RESUMO Introdu ção: Pacientes com anemia falciforme (AF) apresentam hemólise crônica com biomarcadores séricos aumentados. Os polimorfismos genéticos do gene BLC11A modulam a hemoglobina fetal (HbF), reduzindo, assim, a hemólise. Objetivo: Associar os polimorfismos do gene BCL11A aos marcadores ...

D2-40/podoplanin expression in chronic villitis of the placenta
ABSTRACT D2-40/podoplanin (D2-40/PDPN) is a multifunctional protein that can be expressed in lymphatic endothelium and immune cells. D2-40/ PDPN expression in chronic villitis (CV) has not been studied. In 22 cases of CV, we analyzed both D2-40/PDPN expression as well as its coexpression with immune cells markers, and the relationship with stromal cells. In the non-inflamed villi, the D2-40/PDPN positive plexiform pattern has a lymphatic-like conductive network. In the inflamed villi, the D2-40/PDPN expression, predominantly restricted to stromal cells forming a cellular network, is likely related to a phase of the inflamm...

Chondroblastic osteosarcoma of the mandible: case report
We report the case of a 32-year-old male patient, who was subjected to cone-beam tomography for planning the removal of an unerupted tooth. Cone-beam CT scans revealed the presence of a mixed lesion with poorly defined limits in the left posterior mandibular region, with "sun-ray" periosteal reaction. An incisional biopsy was performed and the diagnosis was chondroblastic osteosarcoma. In this paper, a discussion of the differential diagnosis criteria and treatment of this unusual malignant neoplasm is performed. Thus, it is intended to provide information that will help in the study of management protocols for the increas...

Autopsy findings of a child with left atrial isomerism associated with pulmonary agenesis
ABSTRACT Isomerism is a rare laterality defect. Our aim was to describe the autopsy findings of a child with left atrial isomerism (LAI) and pulmonary agenesis (PA), an association still not described in the literature. Fetal ultrasound revealed right renal agenesis, single umbilical artery and polyhydramnios. Echocardiography revealed a complex heart defect with LAI. The child died minutes after birth. Autopsy confirmed the prenatal findings and revealed the presence of unilateral PA, complex vascular abnormalities and polysplenia. Despite its rarity, health professionals should be aware for the possibility of such an ass...

Adipose metaplasia of the thyroid associated with Hashimoto's thyroiditis with nodular hyperplasia and oncocytic cells adenoma: case report and literature review
ABSTRACT Lesions involving adipose tissue and the thyroid gland are usually rare. In the present report, adipose metaplasia is associated with Hashimoto's thyroiditis with nodular hyperplasia and oncocytic adenoma in a 40-years-old female patient, which is one of the first reported cases of this association. The main clinical finding is the diffuse goiter, and the differential diagnosis must be performed to exclude the possibility of malignancies. The treatment is performed through total thyroidectomy. Thus, it is important the physicians be aware of this pathology with a view to a more effective clinical reasoning and to ...

Hereditary thrombophilia by factor V Leiden G1691A (heterozygous) and FII prothrombin G20210A (homozygous) mutations in a patient with ischemic cerebrovascular accident
ABSTRACT Mutations related to Factor V Leiden (G1691A) and prothrombin (G20210A) are associated with a significantly increased risk of venous thromboembolism. The identification of a patient affected by episodes of venous thromboembolism and carrier of G1691A (heterozygous) and G20210A (homozygous) polymorphisms was determined by molecular tests [real-time polymerase chain reaction (PCR) methodology, Genexpert system] during attendance at the Base Hospital of S ão José do Rio Preto-SP, Brazil.RESUMO Muta ções relacionadas com o fator V de Leiden (G1691A) e a protrombina (G20210A) estão associadas a um significativo au...

The role of cytogenetics and molecular biology in the diagnosis, treatment and monitoring of patients with chronic myeloid leukemia
ABSTRACT Chronic myeloid leukemia (CML) is the most common myeloproliferative disorder among chronic neoplasms. The history of this disease joins with the development of cytogenetic analysis techniques in human. CML was the first cancer to be associated with a recurrent chromosomal alteration, a reciprocal translocation between the long arms of chromosomes 9 and 22 - Philadelphia chromosome. This work is an updated review on CML, which highlights the importance of cytogenetics analysis in the continuous monitoring and therapeutic orientation of this disease. The search for scientific articles was carried out in the PubMed ...

Prevalence and antimicrobial susceptibility profile of microorganisms in a university hospital from Vitória (ES), Brazil
ABSTRACT INTRODUCTION: Healthcare associated infections (HAIs) occur during the hospital stay as a result of underlying morbidity, invasive procedures, acute pathology or medical treatment. They lead prolonged stay and, consequently, to an increase in financial charges. The main tool to control these infections is the use of antimicrobials. However, the increase in resistance and the low frequency of discovery of new drugs justify the research that evaluates the resistance profile of microorganisms to antimicrobials. OBJECTIVE: To evaluate the prevalence and antimicrobial susceptibility profile of HAIs at a philanthropic...
