Review[Diagnosis and treatment of mycobacterial infections in patients with HIV/AIDS].
Mycobacterial infection remains as a frequent complication associated to HIV infection. Although the widespread use of HAART has intensely decreased incidence of disseminated Mycobacterium avium (MAC) infection, it does not seem that it has affected tuberculosis occurrence so intensely. In spite of the intense search of new methods of rapid diagnosis, in the clinical practice the diagnosis of the mycobacterial illnesses continues based on culture, although the appearance of new media has allowed to shorten the time of growth. ⋯ The emergence of strains of Mycobacterium tuberculosis resistant to the antituberculosis drugs, the lack of adherence to treatment, and the frequency of adverse events hinders even more the control of the tuberculosis and they demand a narrow follow up of these patients. The treatment of the disseminated infection by MAC has improved in the last years with the generalization of the combinations including macrolides as claritromicin or azitromicin with ETB. The doubt persists about what combination is more effective, although like in other opportunists infections associated with a severe immunodeficiency, using antiretrovirals combinations that enhance the immune system could be a fundamental therapeutic approach.

Refractory hypotension is the main cause of death of patients with septic shock. It has been shown that an excessive release of NO is responsible for the sepsis-induced hypotension and vascular hyporeactivity. ⋯ Randomized clinical trials have shown that the administration of inhibitors of NO synthesis to patients with septic shock is associated with a greater incidence of shock resolution, without significant adverse effects. The recent discovery of the different biological functions of NO, both under normal and inflammatory conditions, has allowed the development of new concepts about the pathophysiology of septic shock, and has provided the bases to design novel therapeutic strategies for the treatment of septic shock, based on the inhibition of NO synthesis.

Review[Infectious bursitis: study of 40 cases in the pre-patellar and olecranon regions].
Septic bursitis usually affects subcutaneous localized bursae such the prepatellar and elbow bursae. This condition is infrequently reported in the spanish medical literature. The aim of this report was to study patients suffering from septic bursitis with regard to predisposing conditions, the causative agents, therapy and clinical outcome. ⋯ The majority of patients with septic bursitis suffered systemic and/or local predisposing illness. S. aureus is the commonest pathogen. Prepatellar septic bursitis is associated with a more aggressive clinical presentation and bacteremia. Usually, the prompt and proper antibiotic therapy make innecessary surgical drainage.
