AIDS-related mycoses: the way forward.

The contribution of fungal infections to the morbidity and mortality of HIV-infected individuals is largely unrecognized. A recent meeting highlighted several priorities that need to be urgently addressed, including improved epidemiological surveillance, increased availability of existing diagnostics and drugs, more training in the field of medical mycology, and better funding for research and provision of treatment, particularly in developing countries

Vitamin D intoxication: a cause of hypocalcaemia and acute renal failure in a HIV patient

Hypercalcaemia in patients with HIV infection is usually associated with specific conditions such as lymphoma and granulomatous diseases. We described a case of severe hypercalcaemia consequent to vitamin D intoxication and secondary renal failure in a HIV patient under tenofovir using. Serum creatinine and calcium returned to near normal levels after vitamin D discontinuation, saline and furosemide administration. Some aspects of the drug-induced nephropathy are discussed

Treatment of severe forms of paracoccidioidomycosis: is there a role for corticosteroids?

Despite their immunosuppressive effects, corticosteroids have long been used as adjunct therapy (aCST) in the treatment of infectious diseases. The rationale is that in certain infections it is necessary to decrease the exacerbated host's inflammatory response, which can otherwise result in tissue damage and organ dysfunction. In fact, a major concern in treating paracoccidioidomycosis (PCM) is the host's intense inflammatory response to Paracoccidioides brasiliensis, which can be further intensified by antifungal therapy. Depending on its localization, this immunological phenomenon may be life threatening or result in permanent sequels, as is the case for some patients with cerebral or laryngeal involvement. However, the literature on aCST in paracoccidioidomycosis treatment is scarce and as a result we present our recent experience in the management of four patients with severe PCM manifestations, i.e., cerebral paracoccidioidal granuloma, laryngeal stenosis, compressive abdominal mass, and exacerbated inflammatory response with tissue destruction. In addition to the antifungal therapy, these patients required aCST, which probably promoted their clinical improvement and/or prevented serious complications. We suggest that aCST: (a) can potentially help in the management of selected cases of severe forms of PCM, particularly when there is a risk of acute complications, and (b) that it can be used safely provided that the risk-benefit ratio is carefully weighed. Well-controlled, prospective studies of aCST in the treatment of severe cases of paracoccidioidomycosis are needed to better define its role in the management of PCM

Potencialidade do conceito de vulnerabilidade para a compreensão das doenças transmissíveis

O artigo traz a evolução e a contribuição da produção científica relacionada ao conceito de vulnerabilidade e sua potencialidade em estudos das doenças transmissíveis. Apresenta-se o conceito de Vulnerabilidade e a produção do conhecimento em Enfermagem, particularmente desenvolvida no Grupo Pesquisa Vulnerabilidade, Adesão e Necessidades em Saúde, do CNPq. Tem como finalidade ampliar a compreensão de agravos de saúde, com base neste conceito, além de possibilitar a proposição de intervenções para o seu enfrentamento, que extrapolem o âmbito do indivíduo, mas contemple a organização do trabalho nos serviços de saúde e a determinação social do processo saúde-doença
