Systematic review on the treatment of ischaemic colitis.

AIM: Ischaemic colitis is uncommon. Aetiological factors include abdominal aortic surgery, drugs (especially inotropics) or rheumatoid diseases, such as Takayasu's or Buerger's diseases. However, there is often no triggering factor, and it may be part of multifactorial cardiac, respiratory, renal or metabolic failure. METHOD: A systematic review of the current literature on the management of ischaemic colitis was carried out. RESULTS: Ten retrospective trials (841 patients) were included. No randomized controlled or prospective trial of the management of ischaemic colitis was found. CONCLUSION: There is very little evidence base for the management of this condition.

[In situ ductal carcinoma of the breast: current status and our experience]. / Il carcinoma duttale in situ della mammella: situazione attuale e nostra esperienza.

INTRODUCTION: Selecting the appropriate treatment strategy for the individual patient with DCIS represents a major challenge to the surgeon treating breast cancer in the 1990's. CASES AND METHODS: In this study 48 "pure" DCIS patients, treated at Surgical Department of Genoa University, have been selected and divided into Van Nuys prognostic groups. New prognostic classification (Van Nuys) defines three distinct and easily recognizable groups, each of which has a different likelihood of local recurrence if treated with breast conservation. RESULTS: Our results confirm that the risk of local recurrence increases in close relation with prognostic classification groups and suggests that different forms of DCIS may require different treatments.
