[Massive hookworm infection as a cause of intestinal bleeding and severe anemia]. / Infección masiva por Ancylostoma duodenale como causa de hemorragia intestinal y anemia severa.

Overt gastrointestinal bleeding caused by hookworm infection is rarely reported. We present a 34 year old male with lower gastrointestinal bleeding with evidence of massive hookworm infection on colonoscopy and discuss the need to consider hookworm infection as a possible etiology of gastrointestinal bleed in endemic areas.

El sangrado gastrointestinal masivo causado por uncinarias es raramente reportado. El caso de un paciente varón de 34 años que se presentó con hemorragia digestiva baja con evidencia de infección masiva por uncinarias en la colonoscopia es reportado en este manuscrito. Además, se discute la necesidad de considerar la infección por uncinarias como una posible etiología del sangrado gastrointestinal en áreas endémicas...

Noninvasive intestinal amebiasis: Entamoeba histolytica colonization without invasion.

PURPOSE OF REVIEW: Entamoeba histolytica infection remains a major cause of morbidity and mortality worldwide. Although research with the organism began in the late nineteenth century, our understanding of the natural history of the infection remains incomplete and is heavily based on expert opinion. Most persons infected with E. histolytica are carriers with the organism colonizing the large intestine. Host defense mechanisms that prevent invasive diseases are poorly understood. A timely review could lead to renewed interest. RECENT FINDINGS: We herein review 2012 and 2013 publications related to the epidemiology, diagnosis, management and potential mechanisms that enable noninvasive E. histolytica colonization without invasion. SUMMARY: There are several publications that advance our knowledge in the first three categories listed above, but studies of mechanisms for noninvasive E. histolytica colonization are glaringly few.
