State-of-the-art definitions for IAH and ACS are proposed based upon current medical evidence as well as expert opinion. The WSACS recommends that these definitions be used for future clinical and basic science research. Specific guidelines and recommendations for clinical management of patients with IAH/ACS are published in a separate review.

Background:We surveyed the occurrence of physical symptoms among long-term gynaecological cancer survivors after pelvic radiation therapy, and compared with population-based control women.Methods:We identified a cohort of 789 eligible gynaecological cancer survivors treated with pelvic radiation therapy alone or combined with surgery in Stockholm or Gothenburg, Sweden. A control group of 478 women was randomly sampled from the Swedish Population Registry. Data were collected through a study-specific validated postal questionnaire with 351 questions concerning gastrointestinal and urinary tract function, lymph oedema, pelvic bones and sexuality. Clinical characteristics and treatment details were retrieved from medical records.Results:Participation rate was 78% for gynaecological cancer survivors and 72% for control women. Median follow-up time after treatment was 74 months. Cancer survivors reported a higher occurrence of symptoms from all organs studied. The highest age-adjusted relative risk (RR) was found for emptying of all stools into clothing without forewarning (RR 12.7), defaecation urgency (RR 5.7), difficulty feeling the need to empty the bladder (RR 2.8), protracted genital pain (RR 5.0), pubic pain when walking indoors (RR 4.9) and erysipelas on abdomen or legs at least once during the past 6 months (RR 3.6). Survivors treated with radiation therapy alone showed in general higher rates of symptoms.Conclusion:Gynaecological cancer survivors previously treated with pelvic radiation report a higher occurrence of symptoms from the urinary and gastrointestinal tract as well as lymph oedema, sexual dysfunction and pelvic pain compared with non-irradiated control women. Health-care providers need to actively ask patients about specific symptoms in order to provide proper diagnostic investigations and management.

Background: The aim of this treatment planning study was to investigate the potential advantages of intensity-modulated (IM) proton therapy (IMPT) compared with IM photon therapy (IMRT) in nasopharyngeal carcinoma (NPC).

The identification of parathyroid carcinomas is based upon histopathological criteria in which an invasive growth pattern or distant metastasis is demonstrated. A dilemma arises when tumours present with atypical histopathological features but lack direct evidence of malignancy. Recently, reduced expression or loss of the tumour suppressor proteins parafibromin and adenomatous polyposis coli (APC) has been associated with parathyroid malignancy. We report results from APC and parafibromin expression analyses by immunohistochemistry and Western blot in five cases of atypical adenoma, a single case of carcinoma and 54 adenomas without atypical features. Complete loss of APC immunoreactivity and reduced expression of parafibromin was evident in two of the atypical adenomas and in the parathyroid carcinoma. By contrast, all adenomas displayed APC expression, including two cases with hyperparathyroidism 2 gene (HRPT2) mutations and loss of parafibromin expression. We conclude that loss of APC is a frequent molecular event in atypical adenomas and carcinomas, but not in adenomas. Following verification in an independent material, APC could become a valuable tool when assessing parathyroid tumours in the clinical setting. Furthermore, the molecular resemblance of atypical adenomas with carcinoma concerning parafibromin and APC expression indicates that atypical adenomas should be subjects to watchful follow-up.

Lower rates of anastomotic leakage have been reported after rectal resection with a colonic pouch-anal anastomosis than with a conventional straight anastomosis. The microcirculation in the bowel segment that was used for construction of a colonic pouch or a conventional straight anastomosis was examined. Transmural colonic blood flow was measured by laser Doppler flowmetry during the operation before the construction of a straight (n = 16) or pouch (n = 14) anastomosis. The blood flow recordings were first done before dissection of the bowel at one point close to the planned bowel end and at another point 8 cm more proximally. A second recording was done at the same sites after dissection and, where appropriate, after construction of the pouch, but before the anastomosis was completed. In the straight group (end-to-end anastomosis), blood flow levels at the site intended for the anastomosis were significantly decreased following dissection of the bowel. In the pouch group (side-to-end anastomosis), blood flow levels at the site of the anastomosis were similar following dissection of the bowel and pouch construction. It is concluded that unaffected blood flow at the site of the anastomosis of the pouch may be a favourable factor for anastomotic healing.
