These data indicate that the incidence of colostomy related hernia increases with follow up and is significantly higher in patients over the age of 60. Other risk factors, particularly obesity and coexisting cardiorespiratory disease, have no impact.

Penicillamine and zinc can effectively treat Wilson's disease, though the side effects of penicillamine may be severe enough to prompt its suspension. Liver transplantation remains the treatment of choice for end-stage liver disease.

The expression of CD40 in the colonic mucosae of patients with ulcerative colitis is significantly increased and is proportional to the state of activity. The results seem to confirm the hypothesis that a loss of tolerance could be involved in the pathogenesis of this disease.

Restorative proctocolectomy (RPC) is the favorite operation for ulcerative colitis, but it may influence health-related quality of life (HRQL). Our aims were to determine the long-term HRQL of patients and its modifications after a 5-year follow-up and to identify any risk factor for a worse outcome. We enrolled 36 patients submitted to RPC (mean follow-up 8.4 +/- 4.7 years), 36 ulcerative colitis (UC) patients, and 36 healthy subjects. We used a previously validated questionnaire that explored bowel symptoms, systemic symptoms, emotional function, and social function. A series of 17 patients had completed the same questionnaire 5 years earlier. Clinical and surgical factors were investigated. Statistical analysis was performed with Student's t-test, Wilcoxon matched-pairs test, and Fisher's exact test. The scores of the RPC patients were significantly better than those of moderate or severe UC patients, similar to those with remission/mild UC, and higher than those of the controls. The scores of patients interviewed 5 years earlier did not change in the present study, except for patients during the first postoperative year, in whom the scores were now significantly better. The analysis of RPC patients in subgroups showed that the use of drugs, high stool frequency, pouchitis, pelvic complications, and younger age at UC diagnosis worsened the HRQL outcome. We concluded that RPC patients, after a long-term follow-up, had an HRQL similar to that of the remission/mild UC patients. Recently operated patients improved their quality of life mainly because of improved emotional function, and patients who had been operated on for a longer time maintained their HRQL. HRQL is influenced by drugs, stool frequency, pouchitis, postoperative pelvic complications, and age at diagnosis.

Ileostomies were associated with a high frequency of complications, but most could be managed by minor surgical interventions. Patients who are considered for an ileostomy for severe idiopathic constipation should, where possible, have a loop ileostomy through a trephine rather than a laparotomy.

DSS induces colonic inflammation which is modulated by the administration of anti-TNFα. Combining anti-TNFα with Zn acetate offers marginal benefit in colitis severity.

Iron deprivation diminishes the severity of DNBS colitis while supplementation worsens colitis. Zinc and copper status are modified by iron manipulation.
