RESUMO
Paciente femenina de 22 años con antecedente de asma bronquial desde la infancia. Fue derivada al servicio de broncoscopia para ser evaluada por sospecha de tumor endoluminal. Trae a la consulta una espirometría normal. En la tomografía de tórax, se observa una lesión endoluminal en el bronquio fuente izquierdo (BFI). Además de disminución volumétrica del campo pulmonar izquierdo con lateralización mediastínica homolateral y herniación del pulmón derecho hacia la izquierda. En el examen físico, se constataron sibilancias generalizadas en el campo pulmonar izquierdo, sin otra alteración.

La criptococosis afecta predominantemente a pacientes con compromiso de la inmunidad celular. Se presenta el caso de un paciente masculino de 45 años, con antecedentes de VIH y linfoma de Hodgkin, internado por fiebre persistente sin neutropenia. El PET-TC evidenció imágenes hipermetabólicas pulmonares y ganglionares se sospechó recaída de su enfermedad y/o proceso infeccioso. Se realizó BAL, se aisló en cultivo Crytococcus laurentii. Recibió tratamiento con anfotericina B y fluconazol, cultivos de control negativos. Se repitió TC de control sin infiltrados pulmonares y persistencia de adenopatías. Realizó tratamiento con ESHAP evolucionando con buena respuesta.
Cryptococcosis mostly affects patients with cell-mediated immunity involvement. We present the case of a male patient, 45 years old, with history of HIV and Hodgkin's lymphoma, who was admitted to the hospital due to persistent fever without neutropenia. The PET-TC (Positron Emission Tomography - Computed Tomography) showed hypermetabolic pulmonary and lymph node images. We suspected disease relapse and/or the presence of an infectious process. We performed a BAL (Bronchoalveolar Lavage) and Cryptococcus laurentii was isolated in culture. The patient received treatment with amphotericin B and fluconazole, with negative control cultures. The CT control was repeated without pulmonary infiltrates and persistence of adenopathies. The patient received treatment with ESHAP and evolved with good response.
RESUMO
Introducción y objetivo: Encuestas nacionales sobre la práctica broncoscópica se han repetido desde hace tres décadas en el mundo. En Argentina la broncoscopía tiene una larga historia, sin embargo, hay poca información disponible sobre esta práctica. El objetivo del estudio es obtener información sobre las características específicas de las prácticas de prevención de infecciones en los procedimientos broncoscópicos. Métodos: En 2014, distribuimos una encuesta para broncoscopistas y asistentes en la reunión anual de neumólogos. Resultados: Se completaron un total de 41 cuestionarios. No recibió capacitación específica en prevención de infecciones el 68%. Es neumonólogo el 85%. Infecciones, pseudoinfeciones o pseudoepidemias asociadas a broncoscopía fueron registradas por el 7%. No refiere haber sufrido un accidente laboral relacionado con la broncoscopía el 87%. Conoce la conducta a adoptar ante un accidente el 80%. Utiliza detergente enzimático para el proceso de limpieza 97%. Reutiliza este detergente 40%. Ortofitalaldehído, glutaraldehído o ambos es empleado como agente de desinfección de alto nivel (DAN) por el 95%. Realiza DAN sobre el broncoscopio siempre el 75%, lo hace a veces 9% y no lo hace el 14%. Realiza DAN o esterilización sobre material reutilizable el 87%. Los accesorios reutilizables (pinzas o cepillos) son esterilizados, reprocesados con DAN o ambas cosas por el 77%; y sometidos sólo a limpieza de nivel medio por el 12%. Emplea “Single Use Device” 78%, de ellos reprocesa este material 84%. Posee procesador automático el 5%. Conclusiones: Se identificaron características específicas locales de prácticas de prevención de infecciones en los procedimientos broncoscópicos.
Background and objective: Nationwide surveys about bronchoscopic practice have been carried out for three decades over the world. In Argentina, bronchoscopy has a long history; however, little information is available about this practice. The aim of this study is to obtain information regarding specific characteristics of practices to prevent in the bronchoscopy-associated infections. Methods: In 2014, we carried out a survey addressed to bronchoscopists and bronchoscopy assistants at the annual meeting of lung specialists. Results: 41 persons were surveyed. 68% did not receive any specific training in infection prevention practices. 85% were pulmonologists. 7% recorded infections, pseudoepidemics or pseudoinfections. 80% knew how to manage bronchoscopy-related accidents. 97% used enzymatic detergents in the cleaning process. 40% knew when to reuse the detergent. 95% used orthophthaldehyde, glutaraldehyde, or both of them as a high level disinfection agent (HLD). 75% used always HLD to clean the bronchoscope while 9% did it sometimes, and 14% never did it. 87% used HLD or sterilization for reusable materials. 77% sterilized reusable accessories (biopsy forceps or brushes), 77% reprocessed them with HLD, and 12% exposed them to mid level cleaning. 78% used a single device. 84% reprocessed the materials. 5% had an automatic processor. Conclusions: Local specific characteristics on the practice to prevent infections in the bronchoscopic procedures were identified.

BACKGROUND: Pandemic influenza A (H1N1) has emerged rapidly in Argentina since May 2009. Preliminary comparisons with seasonal influenza suggest that H1N1 disproportionately affects younger patients, generally causing mild disease, but in a minority of cases can be lethal. OBJECTIVE: The aim of this study was to develop a clinical tool for the initial management of patients with influenza-like syndrome, within the context of the novel H1N1 virus epidemic, to detect patients who need further investigation (e.g., chest X-ray study) for the diagnosis of pneumonia. METHODS: We prospectively studied 1090 consecutive patients with influenza-like syndrome for a period of 15 days. Based on the presence of inspiratory crackles and the level of transcutaneous pulse oximetry, we selected 217 patients requiring chest X-ray study, and pneumonia was confirmed in all of these patients. RESULTS: Among the patients with pneumonia, 132 viral diagnostic tests were available, from which specimens tested by real-time reverse-transcriptase polymerase-chain reaction (RTPCR) were positive for H1N1 in 61 patients (46%). Comparison between RTPCR-positive and RTPCR-negative patients did not show any significant difference. Eighty-seven randomly selected patients with influenza-like syndrome, but without crackles and with O(2) saturation>96%, received chest X-ray studies; none demonstrated pulmonary infiltrates. CONCLUSION: Within the context of an influenza epidemic with the new H1N1 virus, the use of two simple and accessible clinical signs permits a rapid differentiation between those patients requiring close monitoring vs. those with mild and self-resolving disease.
