ObjectivesTo identify the viral aetiology in adult patients with severe acute respiratory infection (SARI) admitted to sentinel surveillance institutions in Bogotá in 2012.DesignA cross-sectional study was conducted in which microarray molecular techniques for viral identification were used on nasopharyngeal samples of adult patients submitted to the surveillance system, and further descriptions of clinical features and relevant clinical outcomes, such as mortality, need for critical care, use of mechanical ventilation and hospital stay, were obtained.SettingRespiratory infections requiring hospital admission in surveillance centres in Bogotá, Colombia.ParticipantsNinety-one adult patients with acute respiratory infection (55% were female).MeasurementsViral identification, intensive care unit admission, hospital stay, and mortality.ResultsViral identification was achieved for 63 patients (69.2%). Comorbidity was frequently identified and mainly involved chronic pulmonary disease or pregnancy. Influenza, Bocavirus and Adenovirus were identified in 30.8%, 28.6% and 18.7% of the cases, respectively. Admission to the intensive care unit occurred in 42.9% of the cases, while mechanical ventilation was required for 36.3%. The average hospital stay was 9.9 days, and mortality was 15.4%. Antibiotics were empirically used in 90.1% of patients.ConclusionsThe prevalence of viral aetiology of SARI in this study was high, with adverse clinical outcomes, intensive care requirements and high mortality.

We have treated 45 cases of urinary tract infection with cefazolin (i.m.) and cure was achieved in 35 (77.77%). 26 of the 28 patients (92.85%) with acute cystitis who received 250 mg every 12 h for 6–10 days were cured. 17 patients with pyelonephritis received 500 mg every 12 h during 10–14 days and therapeutical success was achieved in 9 of them (52.94%). Laboratory control was carried out at the initiation of therapy, at the end, and 1 month after therapy. Tolerance to injections of cefazolin was considered good and only in one case appeared a mild eosinophilia.

Se presenta el caso de una mujer de 65 años a quien se diagnostica neumonía organizada criptogénica (NOC), como primera manifestación de artritis reumatoide (AR). La paciente presentó tos y posteriormente disnea. La tomografía computarizada de tórax mostró opacidades parenquimatosas con broncograma de aire en los lóbulos superiores. Ocho semanas después presenta criterios clínicos y serológicos para AR, se diagnosticó NOC por biopsia abierta de pulmón, con excelente respuesta clínica y radiológica al tratamiento con corticosteroides

<p>La eritrocitosis es una condición infrecuente en las enfermedades pulmonares crónicas que cursan con hipoxemia; su adecuada aproximación fisiopatológica y clínica no es bien conocida. Aunque la eritrocitosis es una respuesta compensatoria frente a la hipoxemia, sus efectos en la microcirculación pueden afectar parámetros cardiovasculares con deterioro de la sintomatología de pacientes con esta patología. La corrección por medio de la flebotomía puede ser una medida terapéutica útil, pero no hay claridad sobre su indicación en consideración a la evidencia actualmente disponible; de igual forma, existen preocupaciones sobre los desenlaces adversos que podrían generarse con su uso en la reología y en la ferrocinética. Es también desconocida la pertinencia de la flebotomía ante el aparente pronóstico benigno de quienes presentan eritrocitosis en el contexto de una neumopatía crónica. Con la escasa información actual, se hace necesaria la ampliación de la investigación en los tópicos relacionados con la eritrocitosis debida a hipoxemia.</p>
