A rare surgical complication of Crohn's diseases: free peritoneal perforation

BACKGROUND: Free peritoneal perforation is a rare complication of Crohn's disease. METHODS: We evaluated the incidence of free peritoneal perforation among 208 patients with Crohn's disease surgically treated in the period 1992-2000. RESULTS: Five patients (2.4%) suffered from free peritoneal perforation. In 1 patient free peritoneal perforation was the first symptom of Crohn's disease. In 3 cases the perforation was in the small bowel and in 2 in the large bowel. All patients underwent surgery: all cases had a resection of the involved bowel and in two cases an ileostomy was performed in order to prevent severe peritonitis. We did not observed mortality or major complications. CONCLUSIONS: Free peritoneal perforation is rare with about 100 cases reported in literature. No correlation seems to exist with previous corticosteroid treatment. The surgical treatment is mandatory. Simple suture should be avoided. The most appropriate treatment, whenever it is feasible, is resection of the involved bowel with immediate or, in case of severe sepsis, delayed anastomosis

Psoas abscess: a rare complication of Crohn's disease

Psoas abscess is a rare complication of Crohn's disease.METHODS AND MATERIALS: We evaluated the incidence of psoas abscess on 312 patients with Crohn's disease, seen at our institution between 1992-2001. RESULTS: We encountered three cases of psoas abscess (0.9%). One patient was managed with ileocolic resection and immediate anastomosis, while in two patients a percutaneous drainage was first performed and then, after 12 days of total parenteral nutrition, a resection of the diseased bowel with immediate reconstruction was carried out. CONCLUSIONS: A correction of the nutritional deficiencies is mandatory. Percutaneous computed-tomography guided drainage of the abscess with intestinal resection with immediate anastomosis, performed after a parenteral hyperalimentation, should be the method of choice in the management of such patients

High-resolution analysis of male genomes by the addition of nine biallelic polymorphisms to the classic 8-STR forensic haplotype

DNA typing of male-specific polymorphisms is a well-established procedure of molecular analysis. A haplotype of eight different human male Y-specific short tandem repeats (STRs) has been intensively used for forensic casework. This haplotype has also been effectively used to address specific problems of population genetics. A collection of 50 male genomes from our laboratory previously genotyped for 8-Y-STR has been reinvestigated with a battery of eight single nucleotide polymorphisms (SNPs) mapping to the Y-chromosome. The addition of these biallelic markers provided additional identification power. Population investigation revealed genetic structure in Italy, with notably implications in Forensic Genetics. © 2003, Elsevier Science B.V. All rights reserved

Severe gastrointestinal bleeding in Crohn's disease

INTRODUCTION: Acute gastrointestinal bleeding is rare in Crohn's disease. METHODS: We characterized the clinical features and course of such hemorrhage in patients seen at our institution from 1992 to 2000. RESULTS: Five patients had gastrointestinal bleeding during Crohn's disease. All patients had a known Crohn's disease, with a mean duration of the disease of 6 years. The source of bleeding was identified in four patients (80%). Endoscopy was, in all patients, the first diagnostic procedure. An Hartmann total colectomy with closure of the rectal stump and ileostomy was performed in three patients, while two patients with ileal massive bleeding were treated conservatively. One patient had a recurrence of bleeding from the small bowel one week later but he didn't required surgical treatment. One patient with pancolic Crohn's disease died on 10th postoperative day because of multiorgan failure and septic complications. CONCLUSIONS: Gastrointestinal bleeding is rare in Crohn's disease, with a predilection for site of involvement. The preoperative diagnosis of the site of bleeding is not easy, and enteroscopy should be mandatory in such patients. Surgery is required for half of cases and recurrent haemorrhage should be an appropriate indication for surgery
