6. Cost of home and hospital care for patients with cystic fibrosis followed up in two reference medical centers in France.
Match Strength: 4.206
OBJECTIVES: In France, new guidelines for clinical practices concerning cystic fibrosis came out in 2002, underscoring the need for early and intensive management of this disease. Because no recent health economic studies on cystic fibrosis in France were available, we conducted a cost-analysis study before the new guidelines were put into practice, with a view to a later study on the medical and economic impact of these guidelines. METHODS: A cost-analysis study was performed of the inpatient and outpatient costs of patients with cystic fibrosis for the 2000-2001 period. The various direct ... Read More »

PURPOSE: We have previously introduced a minimally invasive technique for the treatment of limited pilonidal disease. In this paper, the results for patients who had at least one year of follow-up are provided. METHODS: All patients operated with the sinus excision technique were studied retrospectively and those who had a follow-up period shorter than 12 months were excluded.

8. Comparison of 18S ribosomal RNA gene sequences of Eurytrema coelmaticum and Eurytrema pancreaticum.
Match Strength: 4.010
The partial 18S rRNA sequences of E. coelmaticum and E. pancreaticum were amplified using conserved primers and an evolutionary tree was constructed using Neighbor-Joining. The percent identity of Eurytrema species with other Dicrocoeliidae varied from 97.5 to 98.2, while the percent identity between the two Eurytrema species was up to 99.3. The tree showed that E. coelmaticum and E. pancreaticum were not situated in the same position, and they formed one cluster with L. collurioni. These results support a confirmation with molecular data that E. coelomaticum and E. pancreaticum are different ... Read More »

10. Percutaneous CT scan-guided drainage vs. antibiotherapy alone for Hinchey II diverticulitis: a case-control study.
Match Strength: 3.974
PURPOSE: CT-scan-guided percutaneous abscess drainage of Hinchey Stage II diverticulitis is considered the best initial approach to treat conservatively the abscess and to subsequently perform an elective sigmoidectomy. However, drainage is not always technically feasible, may expose the patient to additional morbidity, and has not been critically evaluated in this indication. This study was undertaken to compare the results of percutaneous drainage vs. antibiotic therapy alone in patients with Hinchey II diverticulitis.

14. The CD4(+) regulatory T-cells is decreased in adults with latent autoimmune diabetes.
Match Strength: 3.767
The latent autoimmune diabetes in adults (LADA) is a subgroup of type 1 diabetes, which procession of autoimmune destruction of beta-cells was slower than classic type 1 diabetes. To investigate the pathogenesis of LADA, we examined the lymphocyte subsets including the CD4(+)CD25(+) T-cells in 60 LADA patients and 30 patients of type 2 diabetes and 30 healthy individuals by FACS. And we compared the expression of FOXP3 mRNA in CD4(+) T-cell between 10 patients of LADA and 10 matched healthy individuals by real time PCR. The percent of CD4(+)CD25(+) T-cells were higher (11.89+/-4.96% versus 8 ... Read More »

PURPOSE: The efficacy of Surgisis anal fistula plug in closure of Crohn's anorectal fistula was studied. METHODS: Patients with Crohn's anorectal fistulas were prospectively studied. Diagnosis was made by histologic, radiographic, or endoscopic criteria. Variables recorded were: number of fistula tracts (primary openings), presence of setons, and current antitumor necrosis factor therapy. Under general anesthesia and in prone jackknife position, patients underwent irrigation of the fistula tract by using hydrogen peroxide. Each primary opening was occluded by using a Surgisis anal fistula plug ... Read More »

17. Estimating average annual percent change for disease rates without assuming constant change.
Match Strength: 3.540
The annual percent change (APC) is often used to measure trends in disease and mortality rates, and a common estimator of this parameter uses a linear model on the log of the age-standardized rates. Under the assumption of linearity on the log scale, which is equivalent to a constant change assumption, APC can be equivalently defined in three ways as transformations of either (1) the slope of the line that runs through the log of each rate, (2) the ratio of the last rate to the first rate in the series, or (3) the geometric mean of the proportional changes in the rates over the series. When ... Read More »

19. Clinical and subclinical leaks after low colorectal anastomosis: a clinical and radiologic study.
Match Strength: 3.475
PURPOSE: This study was designed to examine the natural history of subclinical leaks and their effect on bowel function and quality of life and to evaluate water-soluble contrast enema features that predict anastomotic healing after leaks. METHODS: Consecutive patients who underwent low rectal anastomosis were followed up postoperatively for leaks. All leaks were confirmed radiologically with CT scanning and water-soluble contrast enema imaging. Water-soluble contrast enemas were serially repeated to identify healing. Characteristics on initial water-soluble contrast enema were correlated with ... Read More »
