The differential diagnoses for severe enteropathy or severely damaged small intestinal mucosa.

Aim: The aim of this study was to explore the aetiology of severe duodenal mucosal abnormality in consecutive patients who underwent gastroscopy and duodenal biopsy over the past 10 years.

Background: A range of differential diagnoses have been reported for severe duodenal architectural distortion.

Methods: Clinical and laboratory data of all the patients with severe duodenal architectural distortion diagnosed at MidCentral District Health Board (DHB), New Zealand were collected and statistically analysed.

Agricultural intensification leads to higher nitrate levels in Lake Ontario tributaries.

Eutrophication remains the most widespread water quality impairment globally and is commonly associated with excess nitrogen (N) and phosphorus (P) inputs to surface waters from agricultural runoff. In southern Ontario, Canada, increases in nitrate (NO-N) concentrations as well as declines in total phosphorus (TP) concentration have been observed over the past four decades at predominantly agricultural watersheds, where major expansions in row crop production at the expense of pasture and forage have occurred. This study used a space-for-time approach to test whether 'agricultural intensification', herein defined as increases in row crop area (primarily corn-soybean-winter wheat rotation) at the expense of mixed livestock and forage/pasture, could explain increases in NO-N and declines in TP over time.

Symptomatic giant gastric hyperplastic polyp: a case report.

Herein we describe a rare case of a 59-year-old male who was diagnosed with giant hyperplastic polyps after referring with symptoms of abdominal pain and vomiting, and associated red-flag symptoms of unintentional weight loss and early satiety.

Five-year follow-up after cervical cytology and histology discordance: A retrospective cohort study.

Background: Cervical smear cytology and colposcopic biopsy histology are prone to error at both collection and interpretation stages, leading to a large number of discordant cases.

Aims: Investigation of five-year outcomes for women who have cervical cytology that is discordant and higher grade than histology results.

Materials And Methods: A retrospective cohort study was carried out for 111 women with cervical cytology discordant and higher grade than histology, after cytopathological review, over a three-year period.

The prevalence of human papillomavirus in oropharyngeal cancer in a New Zealand population.

Background: The incidence of oropharyngeal cancer (OPC) in New Zealand (NZ) has more than doubled over the last 14 years with 126 cases in 2010. Overseas studies have shown that human papillomavirus (HPV) plays a significant role in the development of these cancers. However, the role of HPV in OPC and the burden on the NZ health system is unclear.
