ABSTRACT
Las enfermedades granulomatosas incluyen una amplia gama de enfermedades. Sin embargo, en la práctica clínica, muchos casos de enfermedad granulomatosa permanecen sin etiología después del examen histológico. Nuestro objetivo fue determinar, a partir de las biopsias de pulmón, pleura y ganglios linfáticos mediastínicos, en los que se informaron granulomas, las características clínicas y los diagnósticos de estos pacientes. Así también la mortalidad a un año de seguimiento. Metodología: Analizamos retrospectivamente biopsias de pulmón, pleura y/o ganglios linfáticos mediastínicos con granulomas de 75 pacientes del Instituto Nacional del Tórax (2012-2016), sus características clínicas y de laboratorio. La información se obtuvo de los registros médicos. Los datos de mortalidad se obtuvieron del registro civil. Resultados: Se determinó una etiología en todos los casos, excepto en 3 (4%). Los diagnósticos más frecuentes fueron tuberculosis (n = 37; 49%) y sarcoidosis (n = 18; 24%). Otras causas fueron silicosis (5,3%), vasculitis (4%) y neumonitis por hipersensibilidad (2,7%). Los pacientes con tuberculosis (TB) tenían parámetros inflamatorios más altos, como velocidad de eritrosedimentación y proteína C reactiva. Además, sólo se encontraron granulomas con necrosis caseosa en pacientes con tuberculosis. En cambio, los pacientes con sarcoidosis tenían lesiones cutáneas y una mayor frecuencia de linfadenopatías. Cuatro (5.3%) pacientes fallecieron a un año de seguimiento: dos debido a neumonía, uno por hipersensibilidad crónica y uno por TB. Conclusión: La tuberculosis y la sarcoidosis fueron las causas más frecuentes de granulomas respiratorios en este estudio retrospectivo. Se logró determinar una etiología en el 96% de los casos, considerando variables clínicas, de laboratorio e histopatológicas para un diagnóstico diferencial correcto.
Granulomatous diseases comprise a wide range of pathologies. However, in clinical practice, many pulmonary granulomas remain without etiology after the histologic examination. Our aim was to determine from the biopsies of the lung, pleura and mediastinal lymph nodes in which granulomas were reported, the clinical characteristics and diagnoses of the patients. Methodology: We analyzed retrospectively biopsies of the lung, pleura and mediastinal lymph nodes with granulomas from 75 patients handled at our institution (2012-2016), as well as their clinical and laboratory data. The information was obtained from medical records. A one-year mortality date was obtained from the civil registry. Main results: A cause was determined in all the cases, except in three of them (4%). The most frequent diagnoses were tuberculosis (n =37; 49%) and sarcoidosis (n =18; 24%). Other causes were silicosis (5.3%), vasculitis (4%) and hypersensitivity pneumonitis (2.7%). Patients with tuberculosis (TB) had higher inflammatory parameters such as erythrocyte sedimentation rate and C-reactive protein. Besides granulomas with caseous necrosis were only found in TB patients. Instead, patients with sarcoidosis had skin lesions and a higher frequency of lymphadenopathy. Four patients (5.3%) died in a one-year of follow-up: two of them because of pneumonia and the other two patients because of chronic hypersensitivity and TB respectively. Conclusion: Tuberculosis and sarcoidosis were the most common causes of respiratory granulomas in this retrospective study. A specific cause was determined in 96% of cases, considering clinical, laboratory and histopathological variables to do a right differential diagnosis.

BACKGROUND: Fetal drug addiction is a serious public health problem. In the United States 10 to 15% of children have been exposed "in utero" to cocaine. In a Chilean public health service, more than 200 offspring of cocaine free base abuser have been detected. AIM: To analyze the clinical and social features of 100 children exposed to cocaine free base during fetal development. PATIENTS AND METHODS: Clinical features of children born from cocaine free base consume mothers were described at birth. During subsequent follow up, growth and development, disease episodes, developmental alterations and social situation were recorded. Data was compared with other newborns from the same health service. RESULTS: Compared to their normal counterparts, exposed children has a lower birth weight, the frequency of premature babies was thrice higher, and small-for-gestational age children were four times more common. There was also a higher prevalence of cardiac malformations, seizures and apnea. Hospital admissions were more frequent, prolonged and required more complex facilities. During follow up, undernutrition and stunting were more prevalent. Psychomotor retardation was present in 67% of children and behavioral disturbances in 93%. Most of these children are governmental protection. CONCLUSIONS: Strategies to prevent drug abuse during pregnancy and its devastating medical and social consequences should be urgently developed (Rev Méd Chile 2000; 128: 1093-1100).

A retrospective and collaborative study was done in Santiago, Chile, in order to obtain national data on birth-weight, height and head circumference of babies born at 24 to 34 weeks of gestation: 370 babies with reliable gestational age, single pregnancies and no maternal nor fetal morbidity were included in the study. Babies were born in three government and one private hospitals from 1982 to 1987. Mean birthweight, height and head circumference for each gestational age from 24 to 34 weeks are presented in tables with their S.D. and charts +/- 1.5 S.D. The national use of these tables and curves is recommended.
