Both GU (obstruction, incontinence, frequency, cystitis) and GI (diarrhea, proctitis, hemorrhage) systems were evaluated at each follow-up visit greater than 3 months after completing RT.
The existence of correlations between airway obstructions and frequency of malocclusions was frequently refuted [6, 7].
Symptoms reflecting obstruction, urgency and frequency are reported to remain at the same level with time (Potosky et al, 2004; Moinpour et al, 2008) while incontinence is typically reported to increase (Fransson, 2008; Parsons et al, 2009).
Symptoms of urinary irritation, urgency, frequency and obstruction, known as lower urinary tract symptoms, are common in urological practice.
Residents with chronic catheters have a decreased frequency of obstruction with silicone catheters, but this observation is attributed to the larger bore size of the catheter, rather than the catheter material.
In keeping with the nature of biliary tract cancers, non-neutropenic infections were fairly common at some point during the treatment (mostly cholangitis with biliary obstruction), occurring with similar frequency in both arms and usually requiring admission to hospital for biliary drainage and antibiotic therapy.
Figure 7 presents the percentage of sweep in the region upstream of the obstruction for various update frequencies.
Although the American Thoracic Society Statement 41 addresses the relationship of chronic airway obstruction to asbestos exposure, the frequency and severity have been observed to be greater in the Libby cohort.
Statistical differences in the frequency of airway obstruction were tested using Chi-square tests, or Fisher Exact test when the numbers were too low.
When the analysis was run separately in never smokers to discard any possible residual confounding by tobacco, there was a tendency for a higher frequency of airway obstruction in GG subjects as compared to AA+GA (7.1% vs. 0.6%, respectively, p = 0.004 using Fisher's exact test).
