Imaging Findings of the Unusual Presentations, Associations and Clinical Mimics of Acute Appendicitis.

There are many kinds of unusual presentations or associations and clinical mimics of acute appendicitis, and definitive diagnosis requires knowledge of the imaging findings in some cases. The unusual presentations and associations of acute appendicitis included in this study are perforated appendicitis, acute appendicitis occurring in hernias, acute appendicitis with cystic endosalpingiosis, intussusception of appendix, and acute appendicitis with pregnancy. We also present uncommon gastrointestinal, urinary and gynecologic clinical mimics of acute appendicitis including anomalous congenital band, duplication cysts, giant Meckel's diverticulitis, inflammatory fibroid polyp, renal artery thrombosis, spontaneous urinary extravasation and OHVIRA syndrome.

Granulomatous mastitis: is it an autoimmune disease? Diagnostic and therapeutic dilemmas.

Purpose: Granulomatous mastitis (GM) is a rare benign inflammatory breast disease. The clinical presentation of granulomatous mastitis usually mimics malignancy or infection. The aim of this study was to review the clinical and diagnostic features of GM and discuss the medical and surgical treatment of our series of eight GM patients.

Calcium-sensing receptor gene polymorphisms and cardiac valvular calcification in patients with chronic renal failure: a pilot study.

Cardiac valvular calcification (VC) is a frequent finding in chronic hemodialysis patients. In addition to demographic and metabolic factors, genetic susceptibility may also influence the occurrence and severity of these abnormalities and account for interindividual variability among patients. In this report, we studied the relation of calcium-sensing receptor (CaSR) gene polymorphisms to the development of VC in chronic hemodialysis patients.
