RESUMO Objetivos: compreender as noções de ética e bioética e como ser ético e bioético no quotidiano da Atenção Primária à Saúde, a partir do olhar do profissional enfermeiro. Métodos: Estudo de Casos Múltiplos Holístico-qualitativo, fundamentado na Sociologia Compreensiva do Quotidiano, com 54 participantes. Resultados: apresenta a categoria Ser ético e bioético no quotidiano da APS: noções do enfermeiro e duas subcategorias. O ser ético e bioético perpassa por um eu subjetivo e abstrato, cujos medos, anseios e preocupações entrelaçam-se às dimensões humanas e profissionais no quotidiano do trabalho e da relação pessoal-profissional. As noções de ética e bioética emergem da subjetividade, das relações estabelecidas, experiências vividas e ações cotidianas dos enfermeiros essenciais à profissão, ao profissional e ao indivíduo a ser cuidado. Considerações Finais: as noções e atitudes éticas e bioéticas são essenciais às ações assistenciais, gerenciais e organizativas, ao cuidado à saúde, e à segurança de usuários e profissionais.

ABSTRACT Objectives: to understand the perceptions of ethics and bioethics and how to be ethical and bioethical in daily life of Primary Health Care, from the perspective of nurses. Methods: this is a Holistic-qualitative Multiple Case Study, based on Comprehensive Everyday Sociology, with 54 participants. Results: two subcategories and the category Being ethical and bioethical in daily life of PHC: nurses’ perceptions emerged. The ethical and bioethical being permeates a subjective and abstract self, whose fears, anxieties and concerns are intertwined with the human and professional dimensions in daily work and in personal-professional relationship. Ethics and bioethics perceptions emerge from subjectivity, established relationships, lived experiences and daily actions of nurses essential to the profession, professionals and individuals to be cared for. Final Considerations: ethical and bioethical perceptions and attitudes are essential to care, management and organizational actions, health care, and the safety of users and professionals.

RESUMEN Objetivo: comprender las nociones de ética y bioética y cómo ser ético y bioético en la vida diaria de la Atención Primaria de Salud, desde la perspectiva del profesional de enfermería. Método: Estudio de caso múltiple holístico-cualitativo, basado en la sociología integral del día a día, con 54 participantes. Resultados: presenta la categoría Ser ético y bioético en la vida diaria de la APS: nociones del enfermero y dos subcategorías. El ser ético y bioético impregna un yo subjetivo y abstracto, cuyos miedos, ansiedades y preocupaciones se entrelazan con las dimensiones humana y profesional en el trabajo diario y en la relación personal-profesional. Las nociones de ética y bioética surgen de la subjetividad, de las relaciones establecidas, de las vivencias y acciones cotidianas de los enfermeros esenciales para la profesión, el profesional y el individuo a cuidar. Consideraciones finales: las nociones y actitudes éticas y bioéticas son fundamentales para el cuidado, la gestión y las acciones organizativas, la atención de la salud y la seguridad de los usuarios y profesionales.

Introduction: Strongyloides has been shown to infrequently mimic inflammatory bowel disease (IBD) or to disseminate when a patient with IBD and unrecognized strongyloides is treated with immunosupression. Case report: A man from Ecuador, living in Spain for years, with a history of type 2 diabetes mellitus and psoriasis treated with topical corticosteroids, was admitted to the hospital with an 8-month history of diarrhoea. Blood tests showed hyperglycemia, hyponatremia, elevated CRP and faecal calprotectin. Colonoscopy suggested IBD. The patient improved with steroids, pending biopsy results, and he was discharged. Biopies were compatible with IBD, but careful examination revealed strongyloides. He was given a prescription of albendazole. He had to be readmitted due to SIADH, which resolved with fluid restriction. Upon discharge albendazole was prescribed again. The patient skipped most of the out-patient-clinic visits. He returned a year later on 10 mg/week methotrexate, asymptomatic, with 20% eosinophilia, and admitting he had never taken the strongyloides treatment for economical reasons. He then received a week of oral albendazol at the hospital. Biopsies and blood cell count were afterwards normal (eosinophils 3.1%) and serology for strongyloides antibodies was negative. Discussion: This case is of interest for four rarely concurring reasons. It's a worm infection that mimics IBD; the infection was diagnosed by colon biopsy; the infection caused a SIADH; and, most interestingly, even though the patient is on immunosupression, he remains asymptomatic.

We present filaria-nested polymerase chain reaction (PCR), which is based on amplification of first internal transcribed spacer rDNA to distinguish three parasitic filarial species (Onchocerca volvulus, Mansonella ozzardiand Mansonella perstans) that can be found in the Amazon Region. Nested PCR-based identifications yielded the same results as those utilizing morphological characters. Nested PCR is highly sensitive and specific and it detects low-level infections in both humans and vectors. No cross-amplifications were observed with various other blood parasites and no false-positive results were obtained with the nested PCR. The method works efficiently with whole-blood, blood-spot and skin biopsy samples. Our method may thus be suitable for assessing the efficacy of filaria control programmes in Amazonia by recording parasite infections in both the human host and the vector. By specifically differentiating the major sympatric species of filaria, this technique could also enhance epidemiological research in the region.
