Investigação diagnóstica de erros inatos do metabolismo em um hospital universitário

OBJETIVOS: Estabelecer a freqüência de erros inatos do metabolismo (EIMs) em uma amostra de pacientes com hipótese diagnóstica de EIM proveniente do Hospital das Clínicas da Faculdade de Medicina de Botucatu da Universidade Estadual Paulista (UNESP) e analisar a metodologia empregada nessa investigação. AMOSTRA E MÉTODOS: Foram triadas para EIM, por testes químicos e técnicas cromatográficas, 1.233 amostras de urina de 905 pacientes. RESULTADOS: O diagnóstico de EIM foi estabelecido em 18 (1,98%) pacientes; 12 deles apresentaram triagem (testes químicos e cromatografias) alterada para EIM. Todos os pacientes foram diagnosticados por análises enzimáticas. CONCLUSÃO: A freqüência de EIMs diagnosticados neste estudo (1,98%), quando comparada com a literatura, foi satisfatória, uma vez que este grupo de pacientes foi proveniente de um único hospital. A metodologia provou ser eficaz, indicando 12 casos de EIM entre os 18 diagnosticados. O estudo mostra a importância de laboratórios especializados na detecção deste tipo de patologia.

Estudo dos métodos de rotina diagnóstica de mastite no leite de éguas

Routine diagnosis methods used in bovine mastitis were studied in 55 mares in lactation. The findings of strip cup test, California Mastitis Test-CMT, electronic somatic cell count-CCS, microbiological culture, and in vitro antimicrobial susceptibility profile of isolates were discussed. Streptococcus spp., Staphylococcus spp, and enterobacteria were the most common microorganisms isolated in health and CMT-positive mammary glands. Staphylococcus aureus and Arcanobacterium pyogenes were identified in two mares presenting clinical mastitis. Mean somatic cell count of eight mares without presence of microorganisms in milk was 247.57x10³/mL and 1.621,86x10³/mL in 47 mares with positive microbiological culture. Moderate concordance (63.8%) between positive reactions in CMT (1 to 3+) and microbiological culture was observed. Amicacin (78.9%), ceftiofur (74.7%), sulpha-trimetoprim (69,0%) and norfloxacin (69.0%), were the most effective drugs, while resistance of isolates was mainly observed against penicillin (64.8%), gentamycin (35.2%), azithromycin (35.2%), enrofloxacin (28.2%), and florfenicol (28.2%).

Em defesa da categoria de voz média no português

A voz média representa uma categoria flexional das línguas clássicas indo-européias com a função de expressar estados de coisas que afetam o sujeito do verbo ou seus interesses. O português dispõe de um conjunto de predicados, formalmente identificados pelo uso anafórico e não-correferencial do pronome 'se', em que se sustenta a noção de diátese medial. Este trabalho pretende fornecer evidências formais, semânticas e tipológicas para postular uma distinção entre construções médias e reflexivo-recíprocas.

Hemoglobin as AS/alfa talassemia - Importância diagnóstica

Sickle Cell disease is a generic term for a group of genetic disorders characterized by the predominance of hemoglobin S. These disorders include Sickle Cell anemia, the Sickle Cell beta Thalassemia syndromes and Hemoglobinopathies in which hemoglobin S is in association with another abnormal hemoglobin, such as hemoglobin S/C. The Sickle Cell trait (hemoglobin AS) associated with Alpha Thalassemia presents alterations in the red blood cells morphology, usually absent in the heterozygous for this hemoglobin variant. The interaction between hemoglobin Sand alpha Thalassemia has been described as one of the factors responsible for the improvement in the clinical picture of homozygous of hemoglobin S (Sickle Cell Anemia), decreasing the number of episodes of pain. The genetic mechanisms of this influence are evaluated using molecular analyses of the human globin genes. With the objective of verifying the presence of alpha Thalassemia in heterozygous of hemoglobin S, with anemia, sent to the Laboratory of Hemoglobins, Department of Biology, UNESP, São José do Rio Preto, SP, we analyzed 1002 blood samples with Sickle Cell trait, in the period from 1990 to 1998. The samples were picked with EDTA 5% as anticoagulant, after previous authorization of the carriers. Appropriated counseling and management requires definitive diagnosis. For the laboratorial diagnosis the blood samples were submitted to electrophoretic procedures in alkaline and acid pH and cytological evaluation of hemoglobin H. The electrophoretic procedures confirmed the presence of hemoglobin AS. The cytological evaluation evidenced the presence of alpha Thalassemia. Of this total analyzed, 16(1,59%) blood samples presented the association between hemoglobin AS and alpha Thalassemia and two individuals belonged of the same family. Our results addressed us to suggest to the routine laboratories, that is important to accomplish the research of alpha Thalassemia among the Sickle Cell trait, with anemia, to verify the interaction with alpha Thalassemia, supplying to the carriers a important information on its hematological profile, genetic pattern of hemoglobinopathies and the appropriated counseling.

Hemoglobinas anormais e dificuldade diagnóstica

The human hemoglobins, with genetically defined inheritance patterns, have shown characteristic polymorphic variation within the Brazilian population, depending on the racial groups of each region. They have appeared under the form of hemoglobin variants or thalassemias, the variant types S and C and the alpha and beta thalassemias being more common, all of them in heterozygote form. During the year of 1999, blood samples from 506 individuals, with suspected anemia or that had already passed through hemoglobinopathies screening, were sent to the Hemoglobin Reference Center - UNESP for diagnostic confirmation and submitted to electrophoresis proceedings, biochemical and cytological analyses in order to characterize the type of abnormal hemoglobins. The goal of the present study was to verify which abnormal hemoglobin types show greater diagnostic difficulty. The samples came from 24 cities in twelve states. The results showed that 354 (69.96%) individuals presented abnormal hemoglobins, 30 (5.93%) being Hb AS, 5 (0.98%) being Hb AC, 76 (15.02%) suggestive of heterozygote alpha thalassemia, 134 (26.48%) suggestive of heterozygote beta thalassemia and 109 (21.54%) with other forms of abnormal hemoglobin, including rare variants and different forms of thalassemias and variant hemoglobin interactions. It has been concluded that, despite the improved techniques currently available and a constant influx of capacitated personnel, the heterozygote form of thalassemias (210 individuals -41.50%) is challenging to diagnose, followed in difficulty by rare variant characterization and interactive forms of hemoglobinopathies (109 individuals-21,54%), suggesting that the capacity for production of qualified professionals and information about these genetic changes in our population should be increased.

Abordagem diagnóstica dos pacientes com suspeita de trombose venosa profunda dos membros inferiores

Deep venous thrombosis is a relatively common disease, which can present pulmonary embolism as a complication in its acute phase, and later the post-thrombotic syndrome. Thus, diagnosis should be made as soon as possible, in order to prevent or minimize such complications. Several studies have shown that the symptoms and the clinical signs are inaccurate for the deep venous thrombosis diagnosis and that complementary exams are necessary. As an attempt to simplify the patients' assessment, Well et al., in 1997, developed a clinical prediction index that combines symptoms, signs and risk factors for deep venous thrombosis and managed to make a simpler approach through an association of this index with the complementary exams. Phlebography has been considered the gold standard of complementary exams. However, since it is an invasive exam and thus subject to complications, other diagnostic methods were introduced aiming at making the diagnostic approach simpler and less invasive. Doppler ultrasound, duplex scan, impedance plethysmography, computed tomography, and blood tests such as the D-dimer are some of the available methods for assessing the patient with suspicion of deep venous thrombosis. Among them, duplex scan has shown excellent accuracy and it is currently widely accepted as the first choice test for approaching the patient with deep venous thrombosis. Several authors have suggested an association of diagnostic methods to simplify and make the assessment of such patients more cost-effective, leading to the introduction of a wide range of diagnostic strategies. The different diagnostic methods used for assessing deep venous thrombosis are discussed, as well as a review of the literature on the accuracy, advantages and disadvantages of these methods.

Perfil antropométrico e fisiológico de atletas de futsal da categoria sub-20 e adulta

The aim of this study was to determine the anthropometrical and physiological profile of futsal players and compare between under-20 and adults categories. Twenty four male athletes futsal participated in the study. They played in two teams of futsal-level state: a team with players under-20 (12 athletes); and another with players of the adults category (12 athletes). The participants performed a routine assessment involving anthropometric measurements (body mass, size, thickness of skin folds, perimeter body and bone diameter) and tests to estimate the aerobic and anaerobic capacity. The results did not indicate differences in relation to the anthropometrical and physiological profile between the under-20 and adults categories. We concluded that the promotion of athletes from the under-20 category for the adult's category taking into account the anthropometrical profile and aerobic and anaerobic performance indicators is recommended. However, other indicators, such as the technical, tactical and psychological aspects are important to help in understanding this promotion phase and in the training. © FTCD/FIP-MOC.
