Capacidad de respuesta y desafíos del sistema de salud cubano frente a las enfermedades transmisibles / Response capacity and challenges of the Cuban health system against communicable diseases / Capacidade de resposta e desafios do sistema de saúde cubano contra doenças transmissíveis

RESUMEN En el presente artículo se identifican rasgos distintivos y esenciales en las transformaciones del sistema de salud cubano que han permitido la erradicación y disminución de las tasas de incidencia de algunas enfermedades transmisibles a niveles inferiores a 0,1 por 100 000 habitantes. Los resultados obtenidos son consecuencia de la importancia otorgada a la prevención y control de estas enfermedades, así como a los riesgos y daños potenciales. La estructura y funcionamiento del subsistema de higiene y epidemiología y sus interrelaciones con el resto del sistema a partir de los diferentes modelos de prestación de servicios han constituido escenarios de integración permanentes para la toma de decisiones. Se eliminaron enfermedades como la poliomielitis, paludismo, difteria, tosferina, rubéola, parotiditis, meningitis posparotiditis, sarampión, fiebre amarilla, cólera, formas graves de la tuberculosis, rabia humana transmitida por caninos, leishmaniasis, enfermedad de Chagas, la transmisión vertical del virus de inmunodeficiencia humana, sífilis congénita y formas clínicas como el tétanos neonatal y el síndrome de rubéola congénita. Se hace énfasis en algunas enfermedades transmisibles y, en especial, en la respuesta social desarrollada contra la tuberculosis, la lepra, el sida y las enfermedades transmitidas por vectores. Se demuestra que el contexto sanitario actual revela aún desafíos para la sostenibilidad de los logros alcanzados en el país. Garantizar el mantenimiento de la cobertura universal con acceso de la población cubana a los servicios de salud será siempre un principio de la salud pública cubana.

ABSTRACT This article presents distinctive and essential features in the transformations of the Cuban health system that have allowed the eradication and reduction of the incidence rates of some communicable diseases at levels lower than 0.1 per 100 000 inhabitants. The results obtained are a consequence of the importance given to the prevention and control, as well as to the risks and potential damages, of these diseases. The structure and functioning of the hygiene and epidemiology subsystem and its interrelations with the rest of the system, based on the different models of service provision, have been permanent integration scenarios for decision making. Diseases such as poliomyelitis, malaria, diphtheria, whooping cough, rubella, mumps, post-mumps meningitis, measles, yellow fever, cholera, severe forms of tuberculosis, human rabies transmitted by canines, leishmaniasis, Chagas disease, vertical transmission of HIV, congenital syphilis and clinical forms such as neonatal tetanus and congenital rubella syndrome were eliminated. Some communicable diseases are analyzed in more detail and, in particular, the social response developed against tuberculosis, leprosy, AIDS and vector-borne diseases. However, the current health context presents challenges for the sustainability of the achievements made in the country. Assuring the maintenance of universal coverage with access of the Cuban population to health services will always be a principle of Cuban public health.

RESUMO No presente artigo se identificam características específicas e essenciais nas transformações do sistema de saúde cubano que permitiram a erradicação e redução das taxas de incidência de algumas doenças transmissíveis a níveis inferiores a 0,1 por 100 000 habitantes. Os resultados obtidos são uma conseqüência da importância dada à prevenção e controle dessas doenças, bem como aos riscos e danos potenciais. A estrutura e o funcionamento do subsistema de higiene e epidemiologia e suas inter-relações com o resto do sistema, com base nos diferentes modelos de prestação de serviços, constituíram cenários de integração permanente para a tomada de decisões. Foram eliminadas doenças como a poliomielite, malária, difteria, coqueluche, rubéola, parotidite, meningite pós-parotidite, sarampo, febre amarela, cólera, formas graves de tuberculose, raiva humana transmitida por cães, leishmaniose, doença de Chagas, a transmissão vertical do vírus da imunodeficiência humana, sífilis congênita e formas clínicas como o tétano neonatal e a síndrome da rubéola congênita. É dada ênfase a algumas doenças transmissíveis e, em particular, à resposta social desenvolvida contra a tuberculose, a hanseniasis, a AIDS e as doenças transmitidas por vetores. Mostra-se que o atual contexto de saúde revela desafios para a sustentabilidade das realizações no país. Garantir a manutenção da cobertura universal com acesso da população cubana aos serviços de saúde sempre será um princípio da saúde pública cubana.

A clausura enferma: petições para a saída do Convento da Ajuda no Rio de Janeiro para tratamento de doenças contagiosas, c. 1750-1780 / Disease in the cloisters: requests to leave Convento da Ajuda, Rio de Janeiro, for the treatment of contagious diseases, c. 1750-1780

Resumo O artigo discute os pedidos de freiras do Convento da Ajuda para deixar a clausura a fim de curar doenças contagiosas. O padecimento dessas doenças era considerado uma das poucas exceções para permitir a saída das freiras. As ordens femininas guardavam estritamente a clausura, condição necessária para manter o recato de virgens consagradas a Cristo. A documentação contém detalhes sobre as causas e as formas de transmissão das doenças, bem como sobre os tipos de tratamento para combatê-las. Por fim, os processos esclarecem os procedimentos adotados fora da clausura para as freiras não colocarem em risco o recolhimento e a honra, quando iam buscar em locais distantes o tratamento adequado para aquelas doenças.

Abstract This article discusses the requests submitted by nuns from Convento da Ajuda (Ajuda Convent) to leave their life of enclosure to receive treatment for contagious diseases. Disease was one of the few cases in which nuns were granted permission to leave. The female orders were strictly cloistered in order to preserve their purity as virgins consecrated to Christ. Extant documents detail the causes of the diseases, the ways they were transmitted, and the treatments used to fight them. These processes shed light on the procedures adopted outside the cloisters so that the nuns did not jeopardize their reclusion and honor when they went to distant places in search of treatment.

Proceedings of a joint meeting between the Norwegian Society of Infectious Diseases and the Royal Society of Tropical Medicine and Hygiene, Oslo, 20 June 2008.

This paper presents the proceedings of a scientific meeting that was held between the Royal Society of Tropical Medicine and Hygiene and the Norwegian Infectious Diseases Society at Ullevål University Hospital, Oslo on 20 June 2008. Seven speakers updated the audience on recent advances in relevant issues, including international maternal and child health, podoconiosis, schistosomiasis and HIV, leprosy in the UK, rapid diagnostic tests for malaria, delayed diagnosis of tuberculosis and the Global Filariasis Programme. The meeting ended with a series of case presentations.

Zinc and infection: a review.

Dietary zinc deficiency is widespread in developing countries and is often aggravated by intercurrent acute and chronic infections. Recent studies have demonstrated that zinc supplementation can significantly reduce the morbidity and mortality of apparently well-nourished children and shorten the time to recovery from acute infectious diseases. This review summarises current knowledge of the role of zinc in childhood diarrhoea, acute respiratory infections and malaria, and its potential role in diseases associated with impaired cellular immunity, namely tuberculosis, lepromatous leprosy and leishmaniasis, and explores avenues for future research.

[Biological properties and clinical applications of interferon gamma (IFN-gamma)]. / Wlasciwosci biologiczne i kliniczne zastosowanie interferonu gamma (IFN-gamma).

Interferon-gamma (IFN-gamma) is produced by activated T cells and probably by NK cells. Its production can be induced by mitogens, antigens and other molecules. IFN-gamma interacts with cells by binding to specific membrane receptors. IFN-gamma--1b is an Escherichia coli--derived recombinant DNA product, which has biological activity identical to natural human IFN-gamma. This IFN type is a more potent immunomodulator than IFN-alpha and IFN-beta. Long term treatment with a therapeutic dosage of IFN-gamma--1b produces a significant reduction in the incidence of serious infections in patients with chronic granulomatous disease. This cytokine can be also useful in the treatment of patients with visceral leishmaniasis, Epstein-Barr virus infections, lepromatous leprosy and other infectious diseases. Phase I and II studies have demonstrated it to be capable of producing antitumor effects, especially in metastatic renal cell carcinoma and some hematologic malignancies. Clinical trials have suggested efficacy of IFN-gamma in the treatment of severe atopic dermatitis and rheumatoid arthritis. The most common adverse reactions are fever, headaches and erythema at the injection site.

[A new approach to immunotherapy: the transfer factor]. / Un nuovo approccio all'immunoterapia: il transfer factor.

The transfer factor is a tiny molecule capable of transferring the function of the T lymphocytes (immunological memory and retarded hypersensitivity) from a sensitized to a non-sensitized individual. The exact structure and action modalities of the molecule have not yet been precisely established. The difficulties involved in the study of the transfer factor are aggravated by the lack of any suitable experimental model. The attention of immunologists is attracted by this factor which opens up new prospects for the treatment of cancer, immunological deficiencies and certain infectious and autoimmune diseases. More profound research would appear useful to evaluate if and in what cases a potentiation of the immune mechanism can represent an alternative to immunosuppression.
