Although lipomas are encapsulated benign tumors, systemic lipomatosis defines infiltrative nonencapsulated tumors resembling normal adipose tissue. Abdominal lipomatosis and intestinal lipomatosis are different clinicopathological entities with similar clinical symptoms. We describe here a case presenting with upper gastrointestinal bleeding from eroded submucosal lipoma at duodenum secondary t...

Part 1 of this series focused on urinary organic acids as markers of detoxification; part 2 focuses on dysbiosis markers. Intestinal microbial growth is accompanied by the release of products of their metabolism that may be absorbed and excreted in urine. Several organic acids are known to be specific products of bacterial metabolic action on dietary polyphenols or unassimilated amino acids or ...

The short bowel syndrome appears for the reduction of intestinal absorptive surface due to functional or anatomical loss of part of the small bowel. We present the case of a 35-year-old woman with severe short bowel syndrome secondary to acute intestinal ischemia in adults, who presented at 5 years of evolution episodes of dizziness with gait instability and loss of strength in hands. The diagn...

Gastrointestinal (GI) diseases, such as inflammatory bowel diseases (IBD), can manifest themselves with intestinal and extra-intestinal symptoms. Among the latter, cutaneous manifestations, such as pyoderma gangraenosum (PG) and metastatic Crohn's disease (MCD), represent a possible onset of IBD, with or without simultaneous bowel alterations. In such cases, intestinal and skin lesions are supp...

Blastocystis is a widely prevalent intestinal protozoan of man and other animals. It is associated with gastro intestinal disorders and symptoms. Emerging literature suggests that several subtypes of this parasite exist and are responsible for virulence, pathogenicity and symptoms. A variety of new diagnostic methods have been developed which help to recognize genotypic variations, subtype rela...

BACKGROUND Mutations in the NOD2 gene are a significant risk factor to acquire intestinal failure requiring home parenteral nutrition. Tuberculous lymphadenitis is the main manifestation of extrapulmonary tuberculosis. Defects in the innate immunity, including NOD2 mutations, may increase the risk for acquiring infections caused by M. tuberculosis. An association of intestinal failure, mutation...

INTRODUCTION Intestinal parasitic infections have been reported in different regions of Argentina. Giardia intestinalis is recognized as "the national parasite". The aim of this work was to determine the prevalence of both intestinal parasites and G. intestinalis genotypes, as well as to analyze the clinical and epidemiological characteristics in schoolchildren from a suburban community. METH...

BACKGROUND The precise relation of intestinal gas to symptoms, particularly abdominal bloating and distension remains incompletely elucidated. Our aim was to define the normal values of intestinal gas volume and distribution and to identify abnormalities in relation to functional-type symptoms. METHODS Abdominal computed tomography scans were evaluated in healthy subjects (n = 37) and in pati...

BACKGROUND Heterotaxia syndrome involves multiple anomalies, including cardiac malformations and intestinal rotation abnormalities. Most authors recommend routine radiological evaluation, with laparotomy and Ladd procedure if a rotation abnormality is found. AIMS To determine if routine radiological screening is necessary, and if there is a group of children that can safely be managed expecta...

Background. Intestinal atresia refers to complete obstruction or partial stenosis of the intestinal lumen. Prevalence is 1/4000-5000 births, without gender predilection. When the blockage is incomplete, signs such as vomiting, abdominal distension, and constipation may occur shortly after birth or delayed in an unspecified manner. In intestinal atresia, the challenge may not be significant; how...
