Aims: Expanded indications for neuromodulation are continually being explored. We evaluated secondary changes in bowel function after successful neuromodulation for voiding symptoms., Methods: Patients in our prospective neuromodulation database study with comorbid irritable bowel syndrome (IBS), constipation and/or diarrhea, or fecal incontinence (FI) at baseline were evaluated. Pre- and 3, 6, and 12 months post-operative measures included Interstitial Cystitis Symptom Index and Problem Index (ICSI-PI), bowel diaries (assessing bowel movement frequency; constipation, diarrhea, and FI episodes), and scaled global response assessments (GRA) ("markedly worse" to "markedly improved" bowel function)., Results: Most patients reporting secondary bowel problems (128/199; 64.3%) were female (89%; mean age 56 ± 15.4 years). Primary voiding complaints were urgency/frequency (U/F) with or without urinary incontinence (n=74), interstitial cystitis/painful bladder syndrome (IC/PBS; n=43), and urinary retention (n=11). Secondary bowel complaints included constipation and/or diarrhea (49%), IBS (27%), and FI (23%). Urinary (ICSI-PI) scores improved after treatment (P<0.0001 for IBS and constipation/diarrhea; P=0.0021 for FI). Bowel diary data only indicated that mean FI episodes/day increased over time (P = 0.0100) in the FI group. Only the 12-month value (1.4 ± 2.2; n=8) was significantly different from baseline (0.3 ± 0.5; n = 18). On the GRA, only the IBS group consistently reported bowel function improvement versus worsening at each time point. Many reported no change., Conclusions: Studies have indicated that neuromodulation improves FI in carefully selected patients. The impact on other bowel conditions, including IBS, is unclear. Since voiding and bowel symptoms often coexist, it is crucial to fully evaluate all potential treatment benefits., (Copyright © 2010 Wiley-Liss, Inc.)

Right heart catheterization (RHC) is commonly used in the diagnosis and management of acute lung injury (ALI). However, controversy exists regarding RHC. We examined RHC use during the first 3 d of ALI in an observational study of 135 patients defined by American-European Consensus Conference criteria. Study parameters examined for association with RHC included the Acute Physiology and Chronic Health Evaluation (APACHE) III score, lung injury score (LIS), and 20 additional epidemiologic, clinical, and laboratory parameters. RHC was performed in 70 patients (52%) within the first 3 d of ALI. RHC was positively associated (p < 0.05) with a diagnosis of sepsis, APACHE III score, blood urea nitrogen (BUN), creatinine, net fluid balance, and positive end-expiratory pressure. RHC was negatively associated (p < 0.05) with mean arterial pressure (Pa) and PaO2/FIO2. Logistic regression identified four predictors for RHC placement: sepsis, PaO2/FIO2, BUN, and Pa. Initial right atrial and pulmonary artery occlusion pressure measurements demonstrated a moderately strong correlation (r = 0.72). Use of RHC was associated with a change in one or more therapeutic interventions (intravascular fluids, vasopressors, diuretics) in 78% of patients. In summary, patients receiving RHC during the first 3 d of ALI were more severely ill than those who did not receive RHC, and RHC was associated with a change in therapy in most patients.

Our study objective was to assess health-related quality of life in survivors of acute lung injury (ALI) and to supplement generic and disease-specific questionnaires with findings from a focus group of ALI survivors. Six patients participated in the focus group, which revealed patient concerns with amnesia, depressed mood, avoidance behaviors, and a prolonged recovery period. Using a cross-sectional study design, 24 patients completed a questionnaire 6 to 41 mo after their lung injury. A total of 43% of the patients with ALI met criteria for depression; 43% had self-reported significant functional limitations, although 39% had minimal or no limitations. Significant respiratory and psychologic symptoms were reported in a quarter to a third of patients. There were large decrements in all domains of the SF-36 (a generic health-related quality-of-life instrument) in our sample compared with norms previously established for the general population. In addition, our patients had similar physical difficulties compared with previously studied patients with chronic medical illnesses but had more deficits in the social functioning and mental health domains. We conclude that long after lung injury, survivors have significantly lower health-related quality of life than the general population and are likely to have pulmonary and psychologic symptoms.
