RESUMO
Paciente femenina de 58 años sin antecedentes patológicos conocidos, con cuadro de tos crónica expectorante de 7 años de evolución. En la radiografía de tórax posteroanterior se visualiza como hallazgo incidental múltiples imágenes nodulares bilaterales difusas en ambos campos pulmonares por lo que se admite como sospecha de metástasis pulmonares de primario desconocido. Marcadores tumorales negativos y baciloscopía por TBC negativa. Se realiza Tomografía de tórax de alta resolución (TCAR) visualizando los nódulos descritos en la radiografía de tórax por lo que se toma biopsia confirmando el diagnostico de amiloidosis pulmonar. La paciente tiene una evolución favorable con seguimiento ambulatorio por neumología. (provisto por Infomedic International)
58-year-old female patient with no known pathological history, presented with chronic expectorant cough of seven years of evolution. As `incidental finding, posteroanterior chest x-ray revealed multiples diffuse bilateral nodular images in both lung fields. Due to this finding, is admitted as suspicion of pulmonary metastases of an unknown primary neoplasm. Tumor markers and TBC smear were negative. HRCT was performed visualizing the nodules described in the chest x-ray, so a biopsy was taken confirming the diagnosis of pulmonary amyloidosis. The patient has a favorable evolution with outpatient follow-up by pneumology. (provided by Infomedic International)
RESUMO
The digestion efficiency of liquid industrial wastes increases when using bioreactors colonized by microbial biofilms. High concentrations of proteins derived from the fish processing industry lead to the production of ammonia, which inhibits methane production. Two bioreactors were constructed to compare methanogenic activity: one enriched with mMPA (methylaminotrofic methane production archaea) consortia (control bioreactor), and the second with NH3 tolerant consortia (treatment bioreactor). Ammonia tolerant activity was assessed by applying an ammonia shock (755 mg NH3/L). Methane production, consumption of total organic carbon (TOC) and the taxonomic composition of bacteria and archaea was evaluated using 16S rDNA in the acclimatization, ammonia shock, and recovery phases.The ammonia shock significantly affected both methane production and the consumption of TOC in the control reactor (p < 0.05) and taxonomical composition of the microbial consortia (OTU). These values remained constant in the treatment reactor. The analysis of biofilm composition showed a predominance of Methanosarcinaceae (Methanomethylovorans sp., and probably two different species of Methanosarcina sp.) in bioreactors. These results demonstrate that using acclimated biofilms enriched with ammonia tolerant methanogens control the inhibitory effect of ammonia on methanogenesis.

Objetivo: Determinar la efectividad a 3 y 6 meses de una intervención integral para la prevención y tratamiento de caries en dientes permanentes en escolares de 9 a 11 años atendidos por cuatro Unidades Comunitarias de Salud familiar. Metodología: Estudio de intervención comunitaria, cuasi experimental con grupos controles pre y post. Realizada en cuatro Unidades Comunitarias. Para lo cual se tomó una muestra aleatoria de 120 niños y niñas en edades entre 9 y 11 años. Los datos se obtuvieron a través de una guía de observación, utilizando la herramienta informática S-DENT1 para determinar diagnóstico y tratamiento específico. Resultados: La prueba Fisher reflejó que la población estaba concentrada en un nivel regular (1.15 de ISHO) y a los 3 y 6 meses la población se mantuvo en un nivel óptimo, siendo este valor estadísticamente significativo ya que el valor p es inferior a 0.05. El promedio del índice CPO por individuo en la evaluación inicial fue de 3 dientes cariados, 0 dientes perdidos y obturados, posterior a la realización de tratamientos, en la evaluación a 3 y 6 meses la proporción se modificó a 1 diente cariado, 0 perdidos y 2 obturados. Se realizaron 809 sellantes con un 93.45% de supervivencia a los 3 meses y 64.52% en el último control. Se efectuaron 287 obturaciones con 89.55% de supervivencia a la evaluación a los 3 meses y un 75.61% a la evaluación a 6 meses. Conclusión: El abordaje temprano, seguimiento, monitoreo y motivación periódica de la población de estudio son factores fundamentales que influyeron positivamente en la disminución de la carga de placa dentobacteriana y lesiones cariosas activas.
Objective: To determine the effectiveness after 3 and 6 months from a comprehensive intervention for the prevention and treatment of caries in permanent teeth in schoolchildren aged 9 to 11 served by four Community Family Health Centers. Methodology: Quasi-experimental research study of community intervention with pre and post control groups performed in four Community Family Health Centers. For this a random sample of 120 boys and girls between the ages of 9 and 11 was taken. The data was obtained through an observation guide, using the S-DENT1 computer tool to determine diagnosis and specific treatment. Results: The Fisher test showed that the population was concentrated at a regular level (1.15 of OHI) and after 3 and 6 months the population remained at an optimum levelthis value is statistically significant since the p-value is less than 0.05. The average of the DMF Index per individual in the initial evaluation was 3 decayed teeth, 0 lost and 0 sealed teeth; and after performing treatments, the 3 and 6 months evaluation showed that this proportion was modified to 1 decayed tooth, 0 lost and 2 sealed teeth. 809 dental sealant treatments were performed with 93.45% survival after 3 months and 64.52% in the last control. There were 287 fillings with 89.55% survival after 3 months and 75.61% after 6 months. Conclusion: The early approach, monitoring and control, and periodic motivation of the research study population are fundamental factors that positively influenced the decrease in the load of dental plaque and active carious lesions.
