          Abstract

          A crescente disponibilidade de dados de abrangência nacional, organizados em distintos sistemas de informação, requer o desenvolvimento de metodologias para o relacionamento de variáveis constantes em diferentes bases de dados. Este artigo descreve e analisa a metodologia utilizada no relacionamento das bases de dados nacionais do Sistema de Informação de Beneficiários (planos privados de assistência à saúde) e do Sistema de Informação de Mortalidade. Foram analisados os registros de óbitos e os registros de beneficiários no ano de 2004, identificando-se 92.566 óbitos em beneficiários de planos privados de saúde. O rigor na especificidade, em detrimento da sensibilidade do método empregado, não gerou vieses de seleção que pudessem comprometer as análises resultantes. A razão de mortalidade padronizada aponta a subestimação do número de óbitos, além de evidenciar diferenças no risco de morte entre as populações analisadas; no entanto, as diferentes situações de vida e saúde a que estão expostas podem ter interferido nos resultados.

          The increasing availability of nationwide data organized in distinct information systems requires the development of linkage methodologies to identify the relationships between the same variables in different databases. This article describes and analyzes the linkage methodology between two countrywide databases: the Brazilian Mortality System and the database of the population covered by private health insurance. Death registrations and the records of individuals covered by private health insurance in 2004 were analyzed. 92,566 deaths were identified in those covered by private health insurance. The strictness in specificity instead of sensitivity in the method employed did not lead to selection biases that could have compromised the resulting analyses. The standardized mortality ratio (SMR) indicates underestimation of the number of deaths, in addition to showing differences in the risk of death between the populations analyzed; however, different life and health situations may have affected the results.

              Diagnosis and management of G6PD deficiency.

              Glucose-6-phosphate dehydrogenase deficiency, the most common enzyme deficiency worldwide, causes a spectrum of disease including neonatal hyperbilirubinemia, acute hemolysis, and chronic hemolysis. Persons with this condition also may be asymptomatic. This X-linked inherited disorder most commonly affects persons of African, Asian, Mediterranean, or Middle-Eastern descent. Approximately 400 million people are affected worldwide. Homozygotes and heterozygotes can be symptomatic, although the disease typically is more severe in persons who are homozygous for the deficiency. The conversion of nicotinamide adenine dinucleotide phosphate to its reduced form in erythrocytes is the basis of diagnostic testing for the deficiency. This usually is done by fluorescent spot test. Different gene mutations cause different levels of enzyme deficiency, with classes assigned to various degrees of deficiency and disease manifestation. Because acute hemolysis is caused by exposure to an oxidative stressor in the form of an infection, oxidative drug, or fava beans, treatment is geared toward avoidance of these and other stressors. Acute hemolysis is self-limited, but in rare instances it can be severe enough to warrant a blood transfusion. Neonatal hyperbilirubinemia may require treatment with phototherapy or exchange transfusion to prevent kernicterus. The variant that causes chronic hemolysis is uncommon because it is related to sporadic gene mutation rather than the more common inherited gene mutation.
