Cytomegalovirus ileitis associated with goblet cell carcinoid tumour of the appendix

We report a female patient with cytomegalovirus (CMV) terminal ileitis and CMV viraemia, associated with a metastatic goblet cell carcinoid (GCC) tumour of the appendix. She was treated with ileocaecal resection followed by ganciclovir. We highlight the importance of vigilant histopathological assessment and discuss the existing literature on gastrointestinal CMV infection in immunocompetent patients.     

The role of pouch compliance measurement in the management of pouch dysfunction

Purpose  

Ileal pouch anal anastomosis is an established option for patients who require total proctocolectomy and restoration of bowel continuity. However, the functional results are not always good and low pouch compliance has been suggested as one possible cause. We aimed to review the results of pouch compliance tests over 11 years to assess whether measuring pouch compliance is a useful diagnostic tool to guide management of pouch dysfunction.     

Community interventions to promote healthy social environments: early childhood development and family housing. A report on recommendations of the Task Force on Community Preventive Services.

The sociocultural environment exerts a fundamental influence on health. Interventions to improve education, housing, employment, and access to health care contribute to healthy and safe environments and improved community health. The Task Force on Community Preventive Services (the Task Force) has conducted systematic reviews of early childhood development interventions and family housing interventions. The topics selected provide a unique, albeit small, beginning of the review of evidence that interventions do effectively address sociocultural factors that influence health. Based on these reviews, the Task Force strongly recommends publicly funded, center-based, comprehensive early childhood development programs for low-income children aged 3-5 years. The basis for the recommendation is evidence of effectiveness in preventing developmental delay, assessed by improvements in grade retention and placement in special education. The Task Force also recommends housing subsidy programs for low-income families, which provide rental vouchers for use in the private housing market and allow families choice in residential location. This recommendation is based on outcomes of improved neighborhood safety and families' reduced exposure to violence. The Task Force concludes that insufficient evidence is available on which to base a recommendation for or against creation of mixed-income housing developments that provide safe and affordable housing in neighborhoods with adequate goods and services. This report provides additional information regarding these recommendations, briefly describes how the reviews were conducted, and discusses implications for applying the interventions locally.     

Prospective Study Comparing Multislice CT Colonography With Colonoscopy in the Detection of Colorectal Cancer and Polyps

PURPOSE: Multislice CT colonography is an alternative to colonoscopy. The purpose of this study was to compare multislice CT colonography with colonoscopy in the detection of colorectal polyps and cancers. METHODS: Between June 2000 and December 2001, 45 males and 35 females (median age, 68 (29–83) years) with symptoms of colorectal disease were studied prospectively. All patients underwent multislice CT colonography and colonoscopy, and the findings were compared. RESULTS: Colonoscopy was incomplete in 18 (22 percent) patients because of obstructing lesions or technical difficulty, and multislice CT colonography was unsuccessful in 4 (5 percent) because of fecal residue. Colonoscopy was normal in 26 patients and detected 29 colorectal cancers and 33 polyps in 35 patients, diverticulosis in 16 patients, and colitis in 3 patients. Multislice CT colonography identified 28 of 29 colorectal cancers with one false negative and one false positive (sensitivity, 97 percent; specificity, 98 percent; positive predictive value, 96 percent; negative predictive value, 98 percent). Multislice CT colonography identified all 12 polyps measuring 10 mm in diameter (sensitivity, 100 percent), 5 of 6 measuring 6 to 9 mm in diameter (sensitivity, 83 percent), 8 of 15 polyps 5 mm (sensitivity, 53 percent), and false-positive for 8 polyps. The overall sensitivity was 74 percent and specificity 96 percent. The positive predictive value for polyps was 88 percent, and the negative predictive value was 90 percent. Multislice CT colonography also detected 5 of 16 patients with diverticulosis (sensitivity, 31 percent; specificity, 98 percent) and colitis in 2 of 3 patients (sensitivity, 67 percent; specificity, 100 percent). In ten (13 percent) patients, extracolonic findings on multislice CT colonography altered management and included five patients with colorectal liver metastases. In 15 (19 percent) patients, there were incidental findings that did not demand further investigation. CONCLUSIONS: The results from this study indicate that the efficacy of multislice CT colonography in the detection of colorectal cancers and polyps 6 mm is similar to colonoscopy. Multislice CT colonography allows clinical staging of colorectal cancers, outlines the whole length of the colon in obstructing carcinoma when colonoscopy fails, and can identify extracolonic causes of abdominal symptoms.     

Liver fibrosis progression after acute hepatitis C virus infection in HIV-positive individuals

Fibrosis progression after acute hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)-infected patients with follow-up >9 months became similar to reported rates from studies in chronic HIV/HCV coinfection, as measured with transient elastometry. The duration of follow-up and serum alanine transaminase correlated with liver stiffness, and short follow-up resulted in high fibrosis progression rates.
