RESUMO

We describe two new cases of Peptostreptococcus endocarditis, one case of Peptostreptococcus micros prosthetic valve endocarditis and the other of Peptostreptococcus assaccharolyticus tricuspid native valve endocarditis in an intravenous drug user (IDU) patient and review nine cases previously reported.

RESUMO

With the objective of analyzing the usefulness of a new technique of fast detection of pneumococcal antigen in urine (Binax NOW Streptococcus pneumoniae urinary antigen test) 163 community pneumonia episodes were reviewed. The test was positive in 30 cases, and gave rise to therapeutic implications in 12 patients. The global sensitivity was 57%, being superior in patients with HIV infection (70%), and the specificity was 91.6%. In 16 episodes it was the only diagnostic test of pneumococcal infection. The determination of pneumococcal antigen through this technique is a useful tool for the diagnosis of community pneumonia, mainly due its high specificity.

RESUMO

Con el objetivo de analizar la utilidad de una nueva técnica de detección rápida de antígeno neumocócico en orina (Binax NOW Streptococcus pneumoniae urinary antigen test) se revisaron 163 episodios de neumonía comunitaria. La prueba fue positiva en 30 casos, con implicaciones terapéuticas en 12. La sensibilidad global fue del 57 por ciento, siendo superior en pacientes con infección por el virus de la inmunodeficiencia humana (VIH) (70 por ciento) y la especificidad del 91,6 por ciento.En 16 episodios fue la única prueba diagnóstica de infección neumocócica. La determinación de antígeno neumocócico mediante esta técnica es una herramienta útil en el diagnóstico de la neumonía comunitaria, principalmente por su alta especificidad (AU)

RESUMO

BACKGROUND: To analyze the situation of resistance to antituberculous drugs among strains of Mycobacterium tuberculosis recovered in our environment during a five-year period and its relationship with HIV co-infection. PATIENTS AND METHODS: Review of the Mycobacterium tuberculosis strains recovered from patients aged older than 14 years in Hospital Joan March from 1992 to 1996 of which a susceptibility testing study by means of the multiple proportions method was available. The initial or secondary resistance was considered according to the previous antituberculosis treatment antecedent. RESULTS: The susceptibility testing was available from 179 cases (136 males and 43 females) out of a total of 214. The overall resistance rate to any of the tested drugs was 10.1% (18 cases) with a 4% (6 cases) of initial and 38.7% (12 cases) secondary resistances. Co-infection with HIV showed not to be a risk factor for the development of resistance. No significant increase was observed analyzing the temporal trend through the five years studied. CONCLUSIONS: At present, the situation of resistance to Mycobacterium tuberculosis seems not to be alarming in our environment. Co-infection with HIV has not been shown to be associated with an increase in resistance rates.
