Transanal Endoscopic Microsurgery (TEM) for Rectal Cancer: University Hospital of North Tees Experience.

Transanal endoscopic microsurgery (TEM) is a minimally invasive technique that is increasingly being used to treat early rectal cancer (T1/T2). We studied the outcomes of TEM for rectal cancer at our institution looking at the indication, recurrence rate, need for further radical surgery, 30-day and 12-month mortality and complication rate. We performed a retrospective analysis of prospectively collected data of cases between 2008 and 2012: 110 TEM procedures were performed during this period: 40 were confirmed rectal cancers and 70 were benign.

Dynamic QTL analysis and candidate gene mapping for waterlogging tolerance at maize seedling stage.

Soil waterlogging is one of the major abiotic stresses adversely affecting maize growth and yield. To identify dynamic expression of genes or quantitative trait loci (QTL), QTL associated with plant height, root length, root dry weight, shoot dry weight and total dry weight were identified via conditional analysis in a mixed linear model and inclusive composite interval mapping method at three respective periods under waterlogging and control conditions. A total of 13, 19 and 23 QTL were detected at stages 3D|0D (the period during 0-3 d of waterlogging), 6D|3D and 9D|6D, respectively.

The relationship between nonalcoholic fatty liver disease and colorectal cancer: the future challenges and outcomes of the metabolic syndrome.

Nonalcoholic fatty liver disease (NAFLD) is closely related to insulin resistance, metabolic syndrome, obesity, type 2 diabetes, and dyslipidaemia. Obesity and metabolic syndrome are associated with an increased cancer risk, and recent evidence demonstrated an association between NAFLD and colorectal cancer (CRC). The mechanism of how NAFLD can be associated with increased risk of CRC is not fully understood; however, NAFLD represents a condition of profound insulin resistance and a proinflammatory state.

Emergency colectomy for fulminant Clostridium difficile colitis: Striking the right balance.

The number of reported cases of Clostridium difficile (CD) infections has increased markedly worldwide. CD causes a spectrum of clinical syndromes, ranging from mild diarrhea to a very severe illness in the form of pseudomembranous colitis (PMC), toxic megacolon, leading to colonic perforation, peritonitis, and even death. In today's practice, toxic megacolon is more often caused by pseudomembranous colitis than ulcerative colitis.

Preoperative axillary staging in breast cancer-saving time and resources.

This study was performed to assess the feasibility and accuracy of ultrasound guided fine needle aspiration biopsy for axillary staging in invasive breast cancer. Data were collected prospectively from June 2005 to June 2006. In all, 197 patients with invasive breast cancer and clinically nonsuspicious axillary lymph nodes were included.

Venous gangrene and cancer: a cool look at a burning issue.

Venous gangrene (VG) is defined as a clinical triad of skin necrosis and discolouration, documented evidence of venous thromboembolism (VTE) and presence of palpable or doppler-identifiable arterial pulsation. Venous gangrene is rare condition which is associated with poor prognosis in cancer patients. The pathogenesis of VG is multifactorial and could paradoxically be due to warfarin treatment.

Tamoxifen-induced non-alcoholic steatohepatitis: where are we now and where are we going?

Tamoxifen is a cheap and effective estrogen-receptor antagonist, used as the adjuvant hormonal treatment of choice in women with estrogen-receptor-positive breast cancer. Tamoxifen-induced non-alcoholic steatohepatitis (NASH) may increase the demand on oncologists, not only with regard to screening for diabetes, but also for the suggested link of NASH with high incidence of coronary heart disease. At present, there is no guideline for treatment of hyperlipidaemia associated with tamoxifen-induced NASH.

Moderate ischemic mitral regurgitation (IMR) and metabolic syndrome: where are we now and where are we going?

Background: The metabolic syndrome appears to affect 10% to 25% of adult population worldwide. Several studies have described the association between metabolic syndrome and ischaemic heart disease, however, none linked metabolic syndrome to ischemic mitral regurgitation, a serious clinical problem facing both the cardiologists and cardiac surgeons. Ischemic mitral regurgitation is mitral insufficiency caused by myocardial infarction.

Does the type of prosthesis influence the incidence of permanent pacemaker implantation following isolated aortic valve replacement.

Background: The incidence of conduction disorders requiring permanent pacing (PPM) in patients operated on for aortic valve replacement (AVR) has been reported to be 5.7%. However, perioperative risk predictors for PPM following AVR are not well characterized and debate exists regarding selection of the prosthesis-type most likely to minimize this incidence.
