Colorectal cancer (CRC) is one of the leading causes of mortality in the western world. It is widely accepted that neoplasms such as colonic polyps are precursors to CRC formation; with the polyp-adenoma-carcinoma sequences well described in medical literature [1, 2]. It has been shown that Aspirin and other non-steroid anti-inflammatory drugs (NSAID) have a negative effect on polyp and cancer ...
Hereditary non-polyposis colorectal cancer (HNPCC) is characterised by a genetic predisposition to develop colorectal cancer at an early age and, to a lesser degree, cancer of the endometrium, ovaries, urinary tract, and organs of the gastrointestinal tract other than the colon. In the majority of families the disease is linked to mutations in one of the two mismatch repair genes, hMSH2 or hMLH...
BACKGROUND Aberrantly methylated genes are promising biomarkers for the detection of colon adenomas and colorectal cancers (CRCs). The optimal assay type and specific methylated genes for these assays remain to be determined. METHODS We used genomewide microarray-based assays to identify methylated genes as candidate biomarkers for colon neoplasms. The frequency of aberrant methylation of the...
Colonic diverticula are outpouchings of mucosa and submucosa through the large intestine wall. Inverted colonic can be confused with adenoma. It is important to differentiate them. Here we report two cases inverted that seem like adenomas.
Background: Diet therapy in gastrointestinal (GI) surgeries is influenced by site of surgery and its complications. Some GI surgeries are rare so diet therapy becomes complicated. The aim of this report is informed the appropriate nutritional management in wide and rare GI surgeries. Case report: The case is a patient by colon interposition and partial gastrectomy surgery. Complications suc...
To characterize the expression of the mismatch repair gene MutL-homolog 1 (MLH1) in normal colorectal crypts in humans, and assess parameters of its expression as a potential biomarker of risk for colorectal neoplasms, we conducted a pilot, colonoscopy-based case-control study (51 cases, 154 controls) of incident, sporadic colorectal adenoma. Biopsies of normal-appearing rectal, sigmoid, and as...
Background & objective:Primary pleural neoplasms are rare entities compared with the pleural involvement by metastatic carcinoma. The current study aimed at investigating the complete spectrum of pleural neoplasms and differentiating between them with the aid of immunohistochemistry (IHC). Methods: Consecutive pleu...
BACKGROUND Birt-Hogg-Dubé syndrome (BHD) is a dominantly inherited predisposition for development of fibrofolliculomas, trichodiscomas, and acrochordons. Concurrent internal tumors, such as colonic polyps and renal carcinoma, have been described in patients with BHD. OBJECTIVE To evaluate kindreds with familial renal tumors for cutaneous manifestations of BHD. DESIGN One hundred fifty-two p...
Intestinal obstruction is a significant disease specially in patients with previous surgery. Patients symptoms and signs usually are abdominal pain, vomiting, abdominal distention and obstipation. Adhesion bands secondary to previous abdominal surgery is the most common cause of small bowel obstruction and in USA up to 70% of small bowel obstruction is caused by adhesions. In our study adhesion...
background: to determine the colon transit time (ctt) in patients complaining of functional constipation and to evaluate the correlation between abnormal transit times and the types of constipation and the correlation with age and sex. materials and methods: the signs and symptoms of 84 patients with infrequent or difficult defecation, 33 males and 51 females, with a median age of 33.7 were rec...
