Abstract
The impact of the gut microbiome is being increasingly appreciated in health and in various chronic diseases, among them neurodegenerative disorders such as Parkinson's disease (PD). In the pathogenesis of PD, the role of the gut has been previously established. In conjunction with a better understanding of the intestinal microbiome, a link to the misfolding and spread of alpha-synuclein via inflammatory processes within the gut is discussed. In a case-control study, we assessed the gut microbiome of 54 PD patients and 32 healthy controls (HC). Additionally, we tested in this proof-of-concept study whether dietary intervention alone or additional physical colon cleaning may lead to changes of the gut microbiome in PD. 16 PD patients underwent a well-controlled balanced, ovo-lacto vegetarian diet intervention including short fatty acids for 14 days. 10 of those patients received additional treatment with daily fecal enema over 8 days. Stool samples were collected before and after 14 days of intervention. In comparison to HC, we could confirm previously reported PD associated microbiome changes. The UDPRS III significantly improved and the levodopa-equivalent daily dose decreased after vegetarian diet and fecal enema in a one-year follow-up. Additionally, we observed a significant association between the gut microbiome diversity and the UPDRS III and the abundance of Ruminococcaceae. Additionally, the abundance of Clostridiaceae was significantly reduced after enema. Dietary intervention and bowel cleansing may provide an additional non-pharmacologic therapeutic option for PD patients.

Abstract
PURPOSE A prospective evaluation of fifty patients with faecal soiling but normal sphincter function treated by a conservative treatment algorithm. PATIENTS AND METHODS Between January 2010 and January 2011, 50 consecutive patients of two different clinical centres, with faecal soiling and normal anorectal function as assessed by endoanal ultrasound, MRI and anal manometry, were eligible for the purpose of this study. All patients started the therapy by psyllium (PS) and a fibre-rich diet daily after 2 months followed by rectal irrigation (RI) in case of incomplete response and after 4 months by 4 g colestyramine (CO), respectively. The patients completed the Vaizey incontinence score and a 2-week diary card. All tests were performed repeated after 2, 4 and 8 months, respectively. RESULTS The study group consisted of 41 men and 9 women and a mean age of 38 years (21-70). The soiling complaints resolved completely in 37 (79%) patients. After treatment with PS, RI and CO, 12 (24%) patients, 24 (73%) patients and 1 (79%) patient, respectively, resolved completely of faecal soiling. Average weekly soiling frequency, the amount of patients wearing pads daily and the Vaizey incontinence score diminished significantly after treatment with psyllium and after treatment with rectal irrigation (P < 0.001). CONCLUSION Conservative treatment focussed on complete evacuation or clearing the anorectal canal is effective in the treatment of patients with faecal soiling.

Abstract
BACKGROUND A colon free of faecal residue is required for accurate diagnostic colonoscopy. Patient tolerance of his/her colonoscopy cathartic regimen affects patient compliance and willingness to undergo repeated examinations. AIM: To determine whether a meal could be consumed during standard bowel preparation. METHODS This was a randomized, endoscopists' blinded comparison of the tolerability and efficacy of a prepackaged, low-residue diet (NutraPrep) combined with the LoSo Prep bowel cleansing system, which contains magnesium citrate, bisocodyl tablets and a bisocodyl suppository (NP-LS regimen), compared with a clear liquid diet and a double-dose sodium phosphate (Fleet Phospho-soda) regimen (2F regimen). Outcome measures included efficacy of bowel preparation, patient preparation tolerability, side-effects and patient safety. RESULTS A total of 506 patients completed the study, 222 randomized to 2F and 284 to NP-LS. The NP-LS regimen resulted in significantly better colon cleansing in terms of the proportion with good or excellent results (P = 0.025) and in significantly better patient tolerance and willingness to repeat the cathartic preparation (P < 0.01). CONCLUSION The NP-LS regimen proved superior to the 2F regimen.

Abstract
BACKGROUND Currently available aqueous purgatives used before colonoscopy are poorly tolerated. We designed a tableted sodium phosphate purge that we believe will yield much greater patient acceptance. METHODS A total of 305 outpatients undergoing routine diagnostic colonoscopy were randomized to one of three preparation groups: Colyte (100 patients), Fleet Phospho-Soda (106 patients), or sodium phosphate tablets (99 patients). Endoscopists were blinded to the type of preparation administered and answered a questionnaire regarding preparation quality. Patients answered a questionnaire designed to analyze tolerability. Adverse events were closely followed and recorded. RESULTS There were no significant differences in quality of preparation across the groups (80% excellent or good, 4% repreparation). Although hypocalcemia (4 of 71), hypokalemia (18 of 68), and hyperphosphatemia (39 of 69) were observed in patients receiving the tablets, no adverse events occurred. Patients preferred taking the tablets over Colyte and Fleet Phospho-Soda. CONCLUSION The evaluation of a novel delivery system of a sodium phosphate purge is described. Intended for use before colonoscopy, it circumvents the poor taste and excessive volume of ingestion that are aversive to patients. The tableted purgative is equally effective, safe, and greatly preferred over the existing aqueous preparations. This may improve patient compliance with recommendations for screening colonoscopy.
