Tomografia computada de la apendicitis epiploica primaria aguda / Computed tomography of acute primary epiploic appendicitis

La apendicitis epiploica o también llamada apendagitis epiploica consiste en la inflamación de uno de los aproximadamente 100 apéndices epiploicos del colon, habiendo sido descripta tanto en el ascendente como en el descendente. Su conocimiento es important porque constituye una de las causas del abdomen agudo, cuya única sintomatología es el dolor ya que no cursa con alteración de la fórmula leucocitaria ni fiebre, pero de todas maneras el diagnóstico diferencial debe hacerse con otras causas como diverticulitis o apendicitis en primera instancia. La TC es categórica porque muestra la alteración de la densidad del espacio graso entre el colon y la pared abdominal, a diferencia de la apendicitis que se evidencia por dentro y detrás del colon, y sin mayor alteración de la pared colónica a diferencia de la diverticulitis. El tratamiento es conservador, estando indicados analgésicos en los casos de importante dolor. (AU)

Primary epiploic appendicitis is a rare but well known intraabdominal inflammatory process that characteristically presents with an onset of symptoms similar to diverticulitis, appendicitis and other abdominopelvic processes. CT findings are pathognomonic, consistent with a pericolonic oval shaped area of increased density with peritoneal thickening, and fat stranding. The condition is self limited and resolves completely within days under non-steroid antiinflammatory therapy.

Valor diagnostico del dolor abdominal en el tumor desmoide intra-abdominal / Diagnostic value of abdominal pain in intraabdominal desmoid tumor

Desmoid tumors are rare, less than 0,1% of all tumors (6,2%). The word desmoid has been reconized since 1838, and applied to non-encapsulated tumors, of connective origin and locally infiltrative. Generally, their course is painless and the recurrence rate is high if resection has not been complete. Most of these tumors can be found in different anatomic areas, most commonly the anterior abdominal wall although other sites, intra or extraabdominal, have been reported. We describe the case of 50 years old female patient, with abdominal pain caused by an intraabdominal desmoid tumor (AU)

[Symptomatic malignant melanoma of the small intestine]. / Melanoma maligno sintomático de intestino delgado.

A 46-year-old woman presented with abdominal pain, nausea vomiting and abdominal distention. Small bowel x-rays and CT scan of the abdomen revealed small bowel obstruction due to malignant melanoma. The diagnosis of cutaneous melanoma was performed 8 years prior to admission on one lesion in the back. Patient received surgical treatment. Completed resection of an involved jejunal [correction of ileal] segment was performed. Three tumor masses were found at laparotomy. Metastasis from malignant melanoma at the gastrointestinal tract occurs frequently though rarely are these intestinal lesions symptomatic. The efficacy of surgical treatment for symptomatic metastatic melanoma is justified to relief symptoms and prolonged survival.

Campylobacter pylori: associations with antral and fundic mucosal histology and diagnosis by serology in patients with upper gastrointestinal symptoms.

We obtained a sample of serum and mucosal biopsies from the antrum and usually from the corpus of the stomach from 35 symptomatic patients during routine endoscopy to analyze for the relationship between Campylobacter pylori infection, inflammation, and the diagnostic utility of a C. pylori IgG antibody assay. C. pylori was identified prospectively by culture and/or silver stain in gastric biopsies from 24 patients, and the antibody was detected in 19 (79%) of these patients. The antibody assay was positive in three other patients, two of whom had C. pylori, on reexamination of their biopsies. The accuracy of the antibody assay was 83%. Inflammation was detected in all C. pylori-positive antral biopsies (N = 19). However, five (71%) of seven antral biopsies from patients in whom all tests were C. pylori negative, also had inflammation, constituting 17% of all patients with antral gastritis (N = 30). Both antral and fundic mucosa were obtained from 26 patients and, in this group, C. pylori was detected in fundic mucosa from all patients in whom the organism also was present in the antrum (N = 15). In significant (p less than 0.001) contrast to C. pylori-positive antral histology, fundic mucosal histology was normal in 6 (40%) of 15 C. pylori-positive biopsies, all from patients with peptic ulcer disease. We conclude that C. pylori antibody assays will be useful for epidemiological studies and initial screening of the C. pylori status of individual patients. In addition, there is a high concordance rate between antral and fundic mucosa for the prevalence of C. pylori, but in contrast to the probable etiological role of C. pylori in antral gastritis, the organism appears to be only a commensal of fundic mucosa. Moreover, C. pylori infection is not evident in all patients with type B gastritis.

Effect of nifedipine on gastric emptying and gastrointestinal motility in man.

Nifedipine, a calcium-blocking agent, inhibits smooth muscle contractions in various organs including gastric muscle in vitro. Despite this, nifedipine has been found to have no effect on gastric emptying in man. We have investigated the effect of nifedipine on gastric emptying of liquids and solids and on gastrointestinal motility in six healthy subjects. For this, isotopic techniques and manometric methods were used. We confirm that nifedipine 30 mg per os does not modify gastric emptying of liquids or solids. By contrast, antral motility was significantly inhibited (P less than 0.05) and duodenal motility increased. These results could be interpreted as (1) gastroduodenal motility changes are not severe enough to alter emptying or (2) isotopic techniques are not sensitive enough to detect subtle changes in gastric emptying.
