Abstract: haemorrhagic colitis caused by escherichia coli h7-o157. a review and 2 clinical cases e. coli h7: o157 is an emerging infection in chile. two serious cases in our unit permit a review of little known aspects of this disease. it differs from that in developed countries where the average age is 15 years, in chile it affects small children, an with an average age of 1.5 years. this suggests a domestic transmission from an adult who has immunity. the colitis can be severe requiring colectomy, although there are no clear cut indications. it is not proven whether antibiotics increase the incidence of hemolytic uremic syndrome (hus) but is suggested that their early use should be avoided. although the diagnostic method is simple, not all laboratories routinely screen for the organism. treatment should include careful observation, seeking complications e.g. hus and an adequate management of contacts. prevention is based on adequate hygiene of cooking utensils, contact with uncooked meats especially if minced. doctors should seek the aetiology of a haemorrhagic colitis, and health authorities promote information about prevention, and commence obligatory notification of the disease.

Abstract: Resumen Escherichia coli enterohemorrágica O157 H:7 es una infección emergente en nuestro país. Dos casos graves en nuestra unidad permiten actualizar aspectos poco conocidos. A diferencia de países desarrollados (edad media 15 a os), en nuestro país afecta a ni os peque os (media 1,5 a os) indicando probablemente transmisión doméstica desde el adulto, que no enferma por inmunidad. La colitis puede ser grave y requerir colectomía cuyas indicaciones no son precisas. No está comprobado que los antibióticos aumenten la incidencia de SHU pero se sugiere evitar su uso temprano. No todos los laboratorios clínicos buscan este germen aun cuando la técnica es fácil. El tratamiento debe incluir una observación cuidadosa buscando las complicaciones como síndrome hemolítico urémico y un manejo adecuado de contactos. La prevención se basa en buen lavado de utensilios de cocina en contacto con carne cruda, de las manos antes de tomar o alimentar ni os, y la ingestión de carne de vacuno y cerdo bien cocida, en especial si es molida. Proposiciones: El médico debe buscar la etiología, y las autoridades difundir medidas de prevención e instaurar notificación obligatoria. Haemorrhagic colitis caused by Escherichia coli H7-O157.

Abstract: El Síndrome Nefrótico primario (SN) responde favorablemente a corticoides en un 80-90% de los casos. Los pacientes cortico resistentes (SNCR) evolucionan, en su gran mayoría, a insuficiencia renal crónica (IRC). De etiología desconocida, se ha reportado la presencia de un factor de permeabilidad (FP) en el suero de estos pacientes, con algunos efectos conocidos a nivel de otras membranas biológicas, incluyendo el peritoneo. Objetivo: Evaluar las pérdidas proteicas vía peritoneo en ni os con SNCR en diálisis peritoneal crónica (DP). Pacientes y Método: Análisis retrospectivo de 4 a os (2003-2007), Se incluyeron 9 pacientes portadores de SNCR (grupo 1), y un grupo control de 10 ni os en DP portadores de IRC por otra etiología (grupo 2). Se evaluó a los 2 grupos al mes 1 y 6 ó 12 de su ingreso. Los grupos fueron comparables respecto a edad, sexo, peso, superficie corporal, tiempo en DP, concentración de dextrosa utilizada, modalidad dialítica y dosis de diálisis. Resultados: No se observó diferencias de los parámetros bioquímicos (creatinina, nitrógeno ureico, calcio, fósforo). La hormona paratiroidea (PTH) fue significativamente mayor en el grupo control (164 ± 144 vs 564 ± 454 pg/dl p < 0,05), y la albúmina fue menor en los pacientes con SN al inicio (2,27 ± 0,63 gr/dl vs 3,62 ± 1,45 gr/dl p < 0,05) y al final de la evaluación (2,8 ± 0,5 gr/dl vs 3,9 ±0,86 gr/dl, p < 0,05). Las pérdidas proteicas peritoneales fueron significativamente mayores en el grupo 1 vs el grupo 2 al ingreso: 3,41 ± 2,01 vs 1,76 ± 1,45 gr/m2/día, y al final de la evaluación: 4,27 ± 3,47 vs 1,66 ±1,31 gr/m2/día, (p < 0,05) respectivamente. Lo mismo ocurrió con las pérdidas urinarias. No hubo diferencias en la ingesta proteica, KtV peritoneal ni KtV total entre los grupos, mientras que el KtV residual fue significativamente menor en los pacientes nefróticos al término del estudio, sugiriendo una caída más precoz de la función renal residual. Tampoco se observó diferencias respecto a las tasas de peritonitis en el período estudiado. Conclusión: Las pérdidas de proteínas por peritoneo en pacientes en DP portadores de SN, son significativamente mayores que en el resto de los pacientes en DP, y son consistentes con un posible efecto sistémico de un FP en estos pacientes.

Abstract: primary nephrotic syndrome (ns) responds favorably to steroids in 80-90% of cases. most corticoresistant (cr) patients evolve into chronic renal failure (crf), of unknown origin, a permeability factor in these patient's serum has been reported, with some known effects in membranes including the peritoneum. objective: to evaluate peritoneal protein loss in cr children on chronic peritoneal dialysis (cpd). patients and methods: four year retrospective analysis. group 1 included 9 cr children, group 2 was a control group of 10 children with crf of other causes on cpd. children in both groups were comparable in age, gender, weight, body surface, duration of cpd, concentration of solution, modality and dose of dialysis. both groups were evaluated at 1, 6 and 12 months after admission. results: no differences were observes in biochemical parameters: creatinine, urea nitrogen, calcium, phosphorus. pth (parathyroid hormone) was significantly higher in the control group (164 ± 144 vs 564 ± 454 pg/dl p < 0,05), albumin was lower in ns patients at the beginning (2.27 ± 0.63 gr/dl vs 3.62 ± 1.45 gr/dl p < 0,05) and end (2.8 ± 0.5 gr/ dl vs 3.9 ± 0.86 gr/dl, p < 0,05) of the evaluation. peritoneal protein loss was significantly larger in the index group at the beginning (3,41 ± 2,01 vs 1,76 ± 1,45 gr/m7dia), and end (4,27 ± 3,47 vs 1,66 ±1,31 gr/m7dia, (p < 0.05) of the evaluation. the same happened with urinary loss: while there was no difference in protein intake, peritoneal ktv or total ktv between groups, residual ktv was significantly lower among ns patients at the end of the study, suggesting an earlier drop in residual renal function. no differences were observed in rates of peritonitis between groups in the study period. conclusion: peritoneal protein loss in cpd children with ns are significantly larger than other patients in cpd, suggesting a possible systemic permeability factor in these patients.

Abstract: Con la finalidad de conocer la presencia de residuos de antibióticos y sulfamidas en animales de abasto, se analizaron las canales de 300 vacas faenadas en una Planta Faenadora de Carnes de la X Región de Chile. Para ello se obtuvieron muestras de tejido muscular diafragmático y de ri ón que fueron examinadas por el método microbiológico que emplea Bacillus subtilis BGA como cepa sensible, en un substrato de cultivo a tres niveles de pH. De las vacas analizadas, 259 correspondieron a matanza normal y 41 a faenamiento de urgencia. Del análisis de las 300 canales resultaron 13 vacas positivas (4.3%) a la detección de antimicrobianos de las cuales 6 casos correspondieron a vacas de faenamiento normal (2.3%) y 7 muestras a vacas de faenamiento de urgencia (17.1%). Entre las causas más frecuentes de faenamiento de urgencia que presentaron residuos de antibióticos está la mastitis (4 de 10), seguida de cojera ( 2 de 7) y cuerpo extra o (1 de 7). Cotejando los resultados obtenidos en este estudio, con el criterio de decomiso aplicado en otros países, habría correspondido a decomiso total el 2% de la totalidad de las vacas faenadas en el período de muestreo. Considerando las vacas clínicamente sanas y aquellas de faenamiento de urgencia como poblaciones separadas, el decomiso total habría afectado a un 1.5% de las vacas sanas y a un 4.9% de las vacas de faenamiento de urgencia To determine the incidence of antimicrobial residues in slaughtered animals, 300 cow carcasses from a slaughter house the Xth region, Chile were analysed. Muscle and kidney samples were obtained and analysed with the three plates microbiological method which uses Bacillus subtilis BGA as sensible strain included in a nutrient agar at three pH levels (6.0; 7.2 and 8.0). Of the 300 cows analysed, 259 corresponded to normal slaughter and 41 to urgency slaughter. he results show 13 cows positive to antimicrobial residues (4.3%) of the total. Six cases correspond to normal slaughtered cows (2.3%) and seven cases to urgency slaughtered cows (17,1%). The most frequent causes for urgency slaughter among the positive cows were, mastitis (4 from 10), lameness (2 from 7) and strange body (1 from 7). According to the condemnation criteria used in the German legislation, 2% of the 300 cows were affected by complete carcasses condemnation. Considering the normal and urgency slaughtered cows as different populations, condemnation affected 1.5% and 4.9% of the complete cow carcasses respectively
