Acute Small Bowel Obstruction and Small Bowel Perforation as a Clinical Debut of Intestinal Endometriosis: A Report of Four Cases and Review of the Literature.

Endometriosis is a quite common pathology, however, intestinal endometriosis is a rare condition, which typically occurs with chronic symptoms. Its acute presentation is very infrequent. We herein report four cases of intestinal endometriosis, in which the clinical debut occurred acutely: two as an acute small bowel obstruction and two as a small bowel perforation.

Molecularly determined total tumour load in lymph nodes of stage I-II colon cancer patients correlates with high-risk factors. A multicentre prospective study.

Stage I-II (pN0) colorectal cancer patients are surgically treated although up to 25 % will eventually die from disease recurrence. Lymph node (LN) status is an independent prognostic factor in colorectal cancer (CRC), and molecular tumour detection in LN of early-stage CRC patients is associated with an increased risk of disease recurrence and poor survival. This prospective multicentre study aimed to determine the relationship between LN molecular tumour burden and conventional high-risk factors in stage I-II colon cancer patients.

Pathological features and diagnosis of intraductal papillary mucinous neoplasm of the pancreas.

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a noninvasive epithelial neoplasm of mucin-producing cells arising in the main duct (MD) and/or branch ducts (BD) of the pancreas. Involved ducts are dilated and filled with neoplastic papillae and mucus in variable intensity. IPMN lacks ovarian-type stroma, unlike mucinous cystic neoplasm, and is defined as a grossly visible entity (≥ 5 mm), unlike pancreatic intraepithelial neoplasm.

[Association of hyperhomocysteinemia with liver steatosis in patients with chronic hepatitis C].

Background And Objectives: Liver steatosis in chronic hepatitis C (CHC) is related to viral and metabolic factors and likely to genetic factors. The aim of this study was to know if hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR)-C677T polymorphisms are associated with liver steatosis in nonalcoholic patients with CHC.

Patients And Method: In 54 consecutive patients with CHC, alcohol consumption less than 40g/week, and no other causes of liver disease, a liver biopsy was performed.
