O objetivo deste estudo foi estimar e analisar os custos de tratamento da criança com HIV/AIDS em um hospital universitário de São Paulo, Brasil. Foram analisados 291 prontuários de crianças expostas ou infectadas acompanhadas no Instituto da Criança, Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo, em março de 2002. O custo foi estimado por categoria de paciente (exposta e infectada) e nível de gravidade (graves e leves/moderados), com base na quantidade de procedimentos e insumos utilizados no tratamento, e valorizado monetariamente por meio do sistema de apuração de custos existente no Instituto da Criança. O custo total estimado de tratamento da criança exposta ao HIV foi de R$ 956,41 e da criança infectada de R$ 8.092,71 por ano. O custo do tratamento ambulatorial foi de R$ 6.047,28, R$ 3.714,45 e R$ 948,63, respectivamente para os pacientes infectados graves, leves/moderados e para as crianças expostas, e o custo médio de internação foi de R$ 19.353,34, R$ 18.823,16 e R$ 871,03, respectivamente. O custo foi fortemente influenciado pelo consumo de medicamentos e comparável aos obtidos pelos demais estudos publicados, embora inferior ao estimado em estudos internacionais.

The objective of this study was to estimate and analyze the costs of treating children with HIV/AIDS at a university hospital in São Paulo, Brazil. The study collected and analyzed data from 291 medical records of children treated at the hospital as of March 2002. The costs of treatment were estimated for each category of patient (exposed and infected) and severity, based on the quantity of inputs and procedures used in treating each child, based on the cost accounting system used at the hospital. The total cost of treatment for children exposed to the HIV was R$ 956.41 and for those infected with HIV R$ 8,092.71 per year. The mean cost of ambulatory care was R$ 6,047.28 for children with severe conditions, R$ 3,714.45 for those with light/moderate conditions, and R$ 948.63 for the exposed. Hospitalized children had annual costs of R$ 19,353.34, R$ 18,823.16, and R$ 871.03, respectively. The medication was a major factor in the cost of treatment. Our estimates are comparable to the findings from other studies, but lower than corresponding findings from the international literature.

Objetivou-se verificar entre seringas hipodérmicas descartáveis e reutilizáveis qual interfere mais com o vírus vivo presente na vacina contra o sarampo. Vacinas pertencentes a dois lotes foram reconstituídas com os dois tipos de seringas, de modo a formarem dois pools distintos, mantidos à temperatura de +2 a+8°C e protegidos da luz. De cada lote foram realizadas, no mínimo, seis titulações em paralelo, com amostragem a cada hora, de zero a seis horas após reconstituição. A análise estatística dos resultados obtidos nas titulações, feita pelo sistema de retas de regressão demonstrou que embora as vacinas manipuladas com ambos os tipos de seringas apresentassem um decréscimo de título estatisticamente significativo com o decorrer das horas, ele foi bem mais acentuado para as vacinas reconstituídas com seringas reutilizáveis. A menor interferência das descartáveis no título da vacina viva, atenuada contra o sarampo, demonstrou que a preconização e uso desse tipo de seringas pela Secretaria de Estado da Saúde de São Paulo é o ideal e recomendável, por preservar mais a vacina desde a reconstituição até sua administração e, conseqüentemente, a sua eficácia na prevenção dessa infecção.

The study was performed in the State of S.Paulo, SP, Brazil, with the purpose of finding out whether reusable (glass) and disposable hypodermic syringes used for administration of live attenuated measles vaccines would interfere with their virus. At least six different experiments using two distinct lots of vaccines were carried out. Each time, a lot was reconstituted with reusable and disposable syringes in parallel to form separate pools from which samples were collected hourly from zero to the sixtieth hour after reconstitution for virus titration in monolayers of Vero cells. The straight line regression system chosen for the analysis of the results demonstrated that although vaccines reconstituted with both types of syringes presented a statistically significative titer decrease as time went by, there was a more pronounced decrease for vaccines manipulated with the glass syringes. The fact that the disposable syringes affected the titer of the virus present in the live, attenuated measles vaccine less confirmed that the preconization and routine usage of this type of syringe by the Health Department of the State of S.Paulo, Brazil, is ideal and highly recommended because it preserves the vaccine from reconstitution to administration better, and thus, its efficacy in preventing the infection.

Com o objetivo de comparar reações locais e conversão sorológica apresentadas por adultos que receberam o toxóide tetânico através de Ped-o-Jet (via subcutânea) ou de seringa hipodérmica (via intramuscular), o toxóide foi administrado a 472 recrutas do Exército. Em observações realizadas 4 e 24 horas após a vacinação verificou-se que as reações locais dos indivíduos vacinados com Ped-o-Jet eram significativamente mais freqüentes e mais intensas do que aquelas dos vacinados com seringa hipodérmica, não tendo ocorrido, entretanto, reações graves. A conversão sorológica dos não imunes vacinados com Ped-o-Jet ocorreu numa freqüência maior do que nos indivíduos vacinados com seringa hipodérmica. Conclui-se portanto, que o Ped-o-Jet pode ser utilizado em campanhas de vacinação em massa contra o tétano, embora a via de administração preferencial, até o momento, seja a intramuscular.

This paper deals with the administration of tetanus toxoid to 472 army recruits, 50% of which received the vaccine subcutaneously using a Ped-o-Jet pressure injector and the remaining subjects received the vaccine intramuscularly, with hypodermic syringe and needle. The objective was to draw comparative conclusions regarding local reactions and serumconvertion in those young adults. Local reactions were observed four and 24 hours after immunization. Although significantly more frequent and intense in individuals receiving the toxoid by jet injection than in those inoculated with hypodermic syringe, no serious reactions were registered. At the first observation, local reactions occured in 64% of black men vaccinated by Ped-o-Jet and in only 31% of those vaccinated by syringe; 70% of the non-black showed local reactions when vaccinated by Ped-o-Jet and 21% when vaccinated by hypodermic syringe. At the second observation, black men vaccinated by Ped-o-Jet showed local reactions in 78% of the cases and in 3% when vaccinated by syringe; 87% of the non-black had some kind of local reaction when vaccinated by Ped-o-Jet and 17% when the vaccine was administered by syringe. Systemic reactions did not differ in either group. There was no statistical difference between blacks and non-blacks regarding local reactions. Antibody response to vaccination as measured by the paper filter Whatman # 31 technique, after digital punction, occured in a higher frequency in non-immune individuals vaccinated by Ped-o-Jet than in those vaccinated by hypodermic syringe. While in the first ones only 6.6% did not show serumconvertion, 26.9% of those vaccinated by syringe remained susceptible. The jet injector did not have any performance problems and was well accepted by the subjects, Results led to the conclusion that the Ped-o-Jet can be used for mass vaccination against tetanus.
