BACKGROUND: Neurofibromatosis type 1 (NF1: Online Mendelian Inheritance in Man (OMIM) #162200) is an autosomal dominantly inherited tumour predisposition syndrome. Heritable constitutional mutations in the NF1 gene result in dysregulation of the RAS/MAPK pathway and are causative of NF1. The major known function of the NF1 gene product neurofibromin is to downregulate RAS. NF1 exhibits variable clinical expression and is characterized by benign cutaneous lesions including neurofibromas and café-au-lait macules, as well as a predisposition to various types of malignancy, such as breast cancer and leukaemia...

Serrated lesions in the colorectum are currently predominantly classified as hyperplastic polyps (HPs), sessile serrated adenomas/polyps (SSA/Ps), and traditional serrated adenomas (TSAs) according to their morphology. However, the histological morphology and the molecular changes in the serrated lesions are still unclear. We performed immunohistochemistry for Ki67, p16INK4a, and WNT5A in human HPs (n=22), SSA/Ps (n=41), and TSAs (n=19). The distribution of Ki67 and p16INK4a positive cells in TSAs was different from that in HPs and SSA/Ps...

OBJECTIVE: Forkhead box (FOX) proteins are important regulators of the epithelial-to-mesenchymal transition (EMT), which is the main mechanism of cancer metastasis. Different studies have shown their potential involvement in progression of cancer in different tissues such as breast, ovary and colorectum. In this study, we aimed to analyze the expression of genes encoding two FOX proteins in gastric adenocarcinoma. MATERIALS AND METHODS: In this experimental case-control study, the expression of FOXC2 and FOXQ1 was examined in 31 gastric adenocarcinoma tumors and 31 normal adjacent gastric tissues by reverse transcription polymerase chain reaction (PCR)...

A 67-year-old male patient underwent transurethral resection for a bladder tumour at the lower posterior wall found incidentally on imaging for an unrelated disease. The initial histomorphological examination suggested an adenocarcinoma with partial neuroendocrine differentiation. Imaging of the thorax and the abdomen, showed no evidence of another primary tumour. Due to the unusual diagnosis, the case was sent to our department of pathology for expert consultation, which confirmed the diagnosis of a primary mixed adeno-neuroendocrine carcinoma of the bladder (MANEC)...

The pathologic interpretation of gut biopsies in hematopoietic cell transplant recipients to assess graft-versus-host disease (GVHD) is well accepted and supplements clinical and endoscopic findings. However, the histologic activity grading of GVHD is controversial, with attempts to predict prognosis or response to treatment largely unsuccessful. GVHD is being diagnosed earlier in its course, raising the possibility that the pathologic grading system can be profitably modified. We developed a histologic activity grading system designed to replace the commonly used modified Lerner grading systems...

H Listle, C Gutt
The diagnosis ileus is one of the most common indications for an emergency laparotomy. In 70% of the cases, the small intestine is affected, and in 30% it is the colorectum. While stuck hernias are a major cause in developing countries, the most common causes in western countries are postoperative adhesions that lead to an acute bowl obstruction. The timeframe for treatment of a complete mechanical obstruction is short as acute ischemia can lead to necrosis with bowl perforation within 6 h. The perioperative lethality for an emergency laparotomy due to an ileus ranges from 5-15%...

REVIEW
E Rijcken, N Senninger, R Mennigen
Restorative proctocolectomy with ileo-pouch-anal anastomosis is the standard procedure for ulcerative colitis. It provides complete removal of the diseased colorectum, avoids permanent ileostomy and allows the preservation of continence. Functional results and quality of life after restorative proctocolectomy are of great importance. Patients usually have 5-6 bowel movements per day, and continence is satisfactory in more than 90% of patients. A good pouch function strongly correlates with high quality of life...

BACKGROUND: Circadian disruption is a probable human carcinogen. From the eastern to western border of a timezone, social time is equal whereas solar time is progressively delayed, producing increased discrepancies between individuals' social and biological circadian time. Accordingly, western timezone residents experience greater circadian disruption and may be at an increased risk of cancer. METHODS: We examine associations between the position in a timezone (PTZ) and age-standardized county-level incidence rates for total cancers combined and 23 specific cancers by gender using the data of the Surveillance, Epidemiology, and End Results Program (2000-2012), including four million cancer diagnoses in white residents of 607 counties in 11 US states...
