Hepatitis Viral en Chile: actualización al 2006

En las últimas décadas se han producido importantes cambios epidemiológicos, respecto de la incidencia y prevalencia de los distintos tipos de hepatitis viral en nuestro país. De alguna manera estos cambios podrían entenderse como índices de desarrollo, cuando se evalúan las hepatitis que se transmiten enteralmente (virus A y E), infecciones sin frontera en relación a la transmisión por contacto sexual (virus B), desafíos y estrategias acerca del impacto de las transfusiones hace tres décadas (virus C) y otras formas de transmisión y/o agentes no identificados (virus noA-E)

Cirrosis Biliar Primaria

Primary biliary cirrhosis is a chronic, progressive cholestatic liver disease of unknown cause that usually affects middle-aged women and eventually leads to liver failure and the need for liver transplantation. It is diagnosed more frequently now than it was a decade ago because of its greater recognition by physicians and the widespread use of automated blood testing and the antimitochondrial-antibody test, which is relatively specific for the disease. Important advances have been made in our understanding of the natural history, pathogenesis, and treatment of primary biliary cirrhosis since the subject was last reviewed in the Journal. Little has changed in its pathological features, diagnosis, and clinical manifestations.

Hemorragia Digestiva Alta no variceal: Recomendaciones

Se define como hemorragia digestiva alta aquella que se origina en una lesión situada por encima del ángulo de Treitz. Clínicamente, se manifiesta en forma de hematemesis de sangre fresca o en «poso de café», de melenas, de ambas o, con menor frecuencia, como hematoquecia.
La causa más frecuente de hemorragia digestiva alta no varicosa es la úlcera péptica gastroduodenal, que representa alrededor del 70% de los casos, pero también puede ser debida a lesiones agudas de la mucosa gástrica, esofagitis, síndrome de Mallory-Weiss, tumores o lesiones vasculares. La hemorragia digestiva alta no varicosa es una emergencia médica frecuente, con una incidencia anual que oscila entre 50 y 150 casos por 100.000 habitantes.

Dolor Abdominal Recurrente

Recurrent abdominal pain (RAP) is a frequent and troublesome complaint in childhood and adolescence, and the search for a cause and a credible approach to management can be taxing for both family and physician. The term “recurrent abdominal pain” was coined by the British pediatrician John Apley, who first published on the subject in 1958. His definition included at least three attacks of pain occurring over a period of 3  months that were severe enough to affect activities and for which no organic cause was identified. In practice, the definition may include any child or adolescent who has RAP for which the family seeks medical attention and explanation, even if the duration of the pain does not adhere strictly to the Apley definition. The definition explicitly excludes the many causes of acute abdominal pain, which lie outside the scope of this review.

Hepatitis Viral Aguda en Pediatría

La hepatitis viral aguda, corresponde a la inflamación aguda del hígado, ocasionada por los agentes
hepatotróficos clásicos: virus hepatitis A, B, C, D y E. Sin embargo, existen otras causas de
inflamación aguda como otros agentes infecciosos virales (CMV, Epstein Barr, Herpes, enterovirus,
etc.), agentes bacterianos, parasitarios, fúngicos, agentes tóxicos, enfermedades metabólicas,
autoinmunes y alteraciones anatómicas. En Chile, de los pacientes que consultan por un cuadro de
hepatitis viral, sobre el 95% corresponde a infección por virus A.

Diarreas Bacterianas

“Foodborne bacterial diarrhea is an emerging health threat that is attributable to the increased consumption of fresh vegetables and fruits, the challenges associated with producing large quantities of inexpensive foods, the increasing importation of foods from developing regions, and the growing pattern of consumption of foods in public restaurants.1 Of the more than 5.2 million cases of bacterial diarrhea that occur each year in the United States, 80% are a result of foodborne transmission.2 Person to-person spread occurs if only a small amount of a pathogen is required for infection; these pathogens include shigella, Shiga toxin–producing Escherichia coli, and protozoal and viral agents.”
