Prevalencia del síndrome del edificio enfermo en trabajadores de la industria manufacturera / Prevalence of sick building syndrome in manufacturing industry workers

El síndrome del edificio enfermo, se refiere a un conjunto de síntomas generales en mucosa (ocular y/o respiratoria) y piel que presentan los ocupantes de edificaciones con calidad ambiental deficientes, exponiendo a sus ocupantes a factores de riesgos físicos, mecánicos, químicos, biológicos y psicosociales, que puede afectar negativamente la salud y productividad de las personas. Con el propósito de determinar la frecuencia de los síntomas de los ocupantes de una industria manufacturera del Perú, se realizó estudio transversal aplicándose a 237 trabajadores, estratificados por áreas laborales, el cuestionario sugerido por el Instituto Nacional de Higiene y Seguridad en el Trabajo, además de evaluar la condición ambiental mediante la determinación de bioaerosoles cultivables y contables. Los resultados mostraron prevalencia superior al 20% en síntomas como: sequedad en ojos y garganta, picor en garganta congestión nasal, dolor de cabeza y debilidad general. Se tomaron, cuantificaron y caracterizaron 164 muestras de bioaerosoles, los microrganismos encontrados con mayor porcentaje fueron, Aspergillus sp. 54,68% (68) en el área administrativa, mientras que en las áreas de producción y almacén predomino Penicillium sp. con 87,10% (108) y 62,21% (77) respectivamente. Otros géneros encontrados en mayor porcentajes, en las tres áreas fueron: Trichoderma, Acremonium, Monilia, Cladosporium, entre otros. Los hallazgos se correlacionan con lo reportado en diversas investigaciones, la presencia de mencionados hongos, sugiere que existe una inadecuada calidad ambiental y aunada a la prevalencia obtenida en cuanto a sintomatología, se puede clasificar la edificación objeto de estudio con el Síndrome del edificio enfermo(AU)

Sick building syndrome refers to a set of general mucosal (ocular and/or respiratory) and skin symptoms presented by occupants of buildings with poor environmental quality, exposing their occupants to physical, mechanical, chemical, biological and psychosocial, which can negatively affect the health and productivity of people. In order to determine the frequency of the symptoms of the occupants of a manufacturing industry in Peru, a cross-sectional study was carried out, applying to 237 workers, stratified by work areas, the questionnaire suggested by the National Institute of Hygiene and Safety at Work, in addition to to evaluate the environmental condition by determining cultivable and countable bioaerosols. The results showed a prevalence greater than 20% in symptoms such as: dry eyes and throat, itchy throat, nasal congestion, headache and general weakness. 164 samples of bioaerosols were taken, quantified and characterized, the microorganisms found with the highest percentage were Aspergillus sp. 54.68% (68) in the administrative area, while in the production and storage areas, Penicillium sp. with 87.10% (108) and 62.21% (77) respectively. Other genera found in higher percentages in the three areas were: Trichoderma, Acremonium, Monilia, Cladosporium, among others. The findings correlate with what has been reported in various investigations, the presence of these fungi suggests that there is an inadequate environmental quality and, together with the prevalence obtained in terms of symptoms, the building under study can be classified with the Sick Building Syndrome(AU)

Aspergillosis pulmonar / Pulmonary aspergillosis

RESUMEN Se presenta a una paciente de 50 años de edad, atendida durante 2 años por Consulta de Neumología, en la ciudad de Matanzas. Presentaba bronquitis crónica con tratamiento para la misma, hace 3 meses ingresa por Servicio de Medicina Interna por una neumonía de lenta resolución, asociada un síndrome general. Durante el ingreso se manejan varias posibilidades diagnósticas como: posible tuberculosis pulmonar, neoplasia de pulmón o neumonía a gérmenes atípicos. Se confirmó diagnóstico de aspergilosis pulmonar mediante lavado bronquial por broncoscopio. Se aplicó tratamiento con antifúngicos sistémicos y se logró mejoría clínica y radiológica. En esta paciente no existían evidencias de inmunosupresión (AU).

ABSTRACT We present a female patient aged 50 years, attended for two years in the Pulmonology consultation, in the city of Matanzas. She suffered chronic bronchitis with treatment; three months ago she was admitted in the Internal Medicine Service due to a low resolution pneumonia associated to a general syndrome. During her staying in the hospital several diagnostic possibilities were managed: possible pulmonary tuberculosis, lung neoplasia or pneumonia to atypical germs. The diagnosis of pulmonary aspergillosis was confirmed through bronchial lavage `per bronchoscope. no existían evidencias de inmunosupresión. The pronosis is Lung Aspergilosis due to a bronchial washing for bronchoscopy and the treatment begins with systemic antifúngicos, achieving clinical and radiological improvement. There is no evidence of inmunosupression in the patient (AU).

Micosis pulmonares en pacientes de la Quinta Región: Período 2007-2010 / Frequency of pulmonary mycoses determined by analyzing lung secretion samples

Background: The frequency of pulmonary mycoses has increased in the past few years specially in immunocompromised patients. Aim: To determine the frequency of invasive fungal diseases by analyzing lung secretion samples. Material and Methods: Samples of bronchoalveolar lavage (BAL) tracheal aspiration (TA) and induced sputum (IS) were obtained from patients of five hospitals in the Valparaíso Region for the diagnosis of invasive or non-invasive fungal disease, and pneumocystis (PCP), in the period 2007-2010. Clinical data of patients was obtained reviewing medical records or interviewing attending physicians. The diagnosis considered the clinical condition of the patient (immunocompromised or prior lung damage), computed tomography imaging, direct microscopy and cultures. European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) criteria was used for the diagnosis of invasive fungal diseases. Results: Ninety respiratory samples were received and 39 fungal infections were diagnosed. Eleven were probably invasive, seven were non-invasive and 21 were PCP. All patients with probable invasive disease had neutropenia. Most patients with non-invasive infections had bronchiectasis. Aspergillus fumigatus was the main causing agent in both invasive and non-invasive fungal diseases. Patients with PCP were mostly adults with AIDS and children with leukemia. The total mortality rate of patients with invasive fungal disease was of 73%. No deaths were recorded among patients with non-invasive disease. Among patients with PCP, three of 11 HIV and six of 10 non HIV subjects died. Conclusions: Aspergillus fumigatus predominates both in invasive and non-invasive pulmonary mycoses. The former has a high mortality. PCP occurred mainly in adult patients with HIV-AIDS.
