Prevalence and characteristics of chronic kidney disease among Danish adults with cystic fibrosis

Background

With improved prognosis of CF, comorbidities including chronic kidney disease (CKD) are becoming increasingly important. Identification of those at highest CKD risk is hence a priority.

Kinesiophobia and Its Association With Health-Related Quality of Life Across Injury Locations

Objective

To compare baseline kinesiophobia levels and their association with health-related quality of life across injury locations.

Diffuse excess mucosal collagen in rectal biopsies facilitates differential diagnosis of solitary rectal ulcer syndrome from other inflammatory bowel diseases

Solitary rectal ulcer syndrome (SRUS) is sufficiently uncommon that the clinician or general pathologist may lack familiarity with the disorder and may confuse it with other inflammatory bowel diseases. To evaluate the role of collagen staining in facilitating the differential diagnosis of SRUS, an initial open review was undertaken on 1672 consecutive patients whose 4780 colorectal biopsies were stained with H&E with added saffron to demonstrate collagen. Excess mucosal collagen was present in 39 (2.3%) of these patients. Twenty patients with a diffuse excess of mucosal collagen in biopsies from rectal ulcer margins or from otherwise abnormal rectal mucosa had SRUS; in the remaining 19 patients, excess mucosal collagen was focal (seven ischemic colitis, five collagenous colitis, three adenocarcinoma, and four chronic idiopathic ulcerative colitis). Diffuse excess mucosal collagen never was seen in idiopathic inflammatory bowel disease (128 Crohn's colitis and 446 ulcerative colitis). Blinded reviews then were performed on rectal biopsies from 33 patients with a variety of diagnoses (14 SRUS and 19 controls). Diffuse excess collagen by saffron staining was consistently observed in SRUS but was absent in all 19 controls. Additional blinded reviews were carried out because the collagen staining pattern in ischemic colitis, although focal, could potentially be confused with SRUS. It was possible to differentiate these two diseases blindly from one another by using additional histologic criteria (14 SRUS and 12 ischemic colitis). We conclude that the demonstration of a diffuse excess of mucosal collagen in rectal biopsies facilitates the diagnosis of SRUS and differentiates it from idiopathic ulcerative colitis and Crohn's disease, with which SRUS is often confused, and other inflammatory bowel diseases.Supported in part by United States Public Health Service National Research Service Award AM07113 and NIH Grant PO1 AM32971.This work was presented, in part, at the Annual Meeting of the American Federation for Clinical Research (Western Section), Carmel, California, February 1986.     

Abnormal glucose tolerance is a predictor of steatohepatitis and fibrosis in patients with non-alcoholic fatty liver disease

Objective. The majority of patients with non-alcoholic fatty liver disease (NAFLD) have simple steatosis. A minority, however, present with non-alcoholic steatohepatitis (NASH), a condition that can lead to advanced fibrosis and cirrhosis. The frequencies of NASH and fibrosis among patients with NAFLD and sustained elevation of liver function tests (LFT) are uncertain. Our aim was to estimate these frequencies. We characterize a population with NAFLD, with special emphasis on insulin resistance and the metabolic syndrome, and study possible predictors for different stages of the disease. Material and methods. All referred patients with sustained elevation of LFT, radiological evidence or clinical suspicion of fatty liver, and absence of other liver disease, were invited to participate in our study in the period June 2002 to December 2004. Results. Of 129 patients who met the inclusion criteria, 88 underwent liver biopsy. NAFLD was verified in 83 of them. Among these patients, 59 (71%) had the metabolic syndrome, 41 (49%) had NASH and 36 (43%) had fibrosis. Abnormal glucose tolerance (T2DM or impaired glucose tolerance) was the only independent risk factor for NASH (OR: 3.14; 95% CI: 1.20–8.23). Independent predictors for fibrosis were abnormal glucose tolerance (OR: 3.83; 95% CI: 1.29–11.40) and body mass index (OR: 1.20; 95% CI: 1.06–1.36) per kg/m². Conclusions. Both NASH and fibrosis are frequently present among patients with NAFLD and sustained elevation of LFT. The probability of these potentially progressive stages of NAFLD increases with the presence of abnormal glucose tolerance.     

ASRA Practice Advisory on Neurologic Complications in Regional Anesthesia and Pain Medicine

Neurologic complications associated with regional anesthesia and pain medicine practice are extremely rare. The ASRA Practice Advisory on Neurologic Complications in Regional Anesthesia and Pain Medicine addresses the etiology, differential diagnosis, prevention, and treatment of these complications. This Advisory does not focus on hemorrhagic and infectious complications, because they have been addressed by other recent ASRA Practice Advisories. The current Practice Advisory offers recommendations to aid in the understanding and potential limitation of neurologic complications that may arise during the practice of regional anesthesia and pain medicine.
