Background Constipation has a significant impact on quality of life. Aim of this study was to evaluate the safety and the efficacy for relieving dyschezia symptoms of a CO2-releasing suppository in a randomized, placebo-controlled, clinical trial. Methods Fifty-three office-based primary care physicians and 24 gastroenterologists conducted the study in France, between November 2010 and January 2012. Patients (aged 18-75 years) with dyschezia were eligible. Patients were randomly allocated a once-a-day suppository (CO2-releasing suppository or placebo) for 21 days. Primary endpoint was the change, from Day 0 to Day 21, in the intensity of discomfort related to dyschezia based on a self-assessed 0-100 visual analogue scale. Results A total of 323 patients were randomized, i.e. 166 into the intervention group and 157 into the placebo group. Co-variance analysis showed a greater reduction in discomfort visual analogue scale score in the intervention group (-34.5 mm; standard error of the mean: 1.8 mm) than in the placebo group (-26.2 mm; standard error of the mean: 1.9 mm; p < 0.001). The greater efficacy of the CO2-releasing suppository was confirmed for all secondary efficacy parameters. No significant side effects for either treatment were observed. Conclusion A CO2-releasing suppository is more effective than a placebo for the relief of symptoms of dyschezia. This efficacy is associated with a good safety profile. [ABSTRACT FROM AUTHOR]

Electrical activity of the colon was investigated in six healthy volunteers and 22 patients presenting functional colonic disorders associated with pain, constipation, or diarrhoea. Myoelectrical activity during 10 hours, including two daily meals, was recorded from eight groups of nickel-chrome electrodes using a 1.5 m length probe introduced by the rectal route. Electromyograms of volunteers consisted of slow waves at two distinct rhythms, approximately 3 and 10 cycles per minute, during 16 to 28% of the recording time respectively for each site. Action potentials were also recorded as 11 to 80 short spike bursts (SSB) per hour lasting 1.5 to 3.5 s at any site and 20-26 long spike bursts (LSB) per hour, lasting 17 to 21 s, occurring in series of four to eight propagated bursts. Additional high-velocity propagated bursts were recorded during the three hour postprandial period. Three typical changes in spike activity patterns were detected: an increase by 170-420% of the number of SSB associated to a high spiking activity was recorded in 13 patients (group I), the absence of SSB, a low spiking activity level and only 3 to 8 LSB per hour (group II), in six patients; and the postprandial response was absent (group III) in three other investigated patients. Evidence for three groups of motor disturbances and their possible relation to clinical manifestations of functional disorders is presented. [ABSTRACT FROM PUBLISHER]

Background and Study Aims: The purpose of this study was to describe the real-life conditions of use, efficacy, safety, and acceptability of sodium phosphate (NaP) tablets for colon cleansing in routine medical practice in France., Patients and Methods: A total of 996 patients undergoing bowel preparation were enrolled by 108 gastroenterologists in this observational, longitudinal, prospective, multicenter study. The conditions of use of NaP tablets were assessed with a composite endpoint, which included six criteria for patient compliance with the recommended administration scheme and a criterion for the absence of contraindications to NaP use., Results: Adequate use of NaP was reported for 75.1 % of the patients. The main reasons for misuse were a smaller fluid intake than expected with a dose of 4 tablets and noncompliance with age-related contraindications. The quality of cleansing was satisfactory: the Boston Bowel Preparation Scale (BBPS) total score was 7 or higher in 75.4 % of the patients. Gastroscopy associated with colonoscopy in 38.9 % of the patients revealed gastric lesions, which were considered as possibly related to the use of NaP tablets in 10.3 % of them. Vomiting occurred in 9.8 % of the patients, and 0.6 % discontinued bowel preparation after an adverse event. No electrolyte disorders or renal impairment was reported, even if not systematically sought. The acceptability of the NaP tablets was high, particularly among patients who previously had undergone other methods of bowel preparation., Conclusions: Despite being defined according to strict criteria, adequate use of NaP tablets was observed in a high percentage of patients. The quality of colon cleansing and the safety and acceptability of NaP tablets were satisfactory and consistent with data from randomized clinical studies.

Hemorrhoids are a clinical and anatomical subject that has not been completely investigated. A link between the anatomy and the symptoms has still not been established. For this reason, it is difficult to class the different treatments. Non-surgical treatment is intended not to remove but to reposition and hold the hemorrhoids in an anatomically correct position and the reduce the vascularity. Different techniques have been studies but not all of them have been approved. For the moment, the recognised techniques include: infrared therapy, sclerotherapy, rubber band ligation. Cryotherapy has not been studied in controlled studies. One hopes that new techniques such as Doppler-guided artery ligation will soon be tested and validated.

A new cytochemical assay of acid phosphatase activity employing Triton WR-1339, a non-ionic detergent, has been used to demonstrate the probable origin of the phytolysosome system and of the organization of the Golgi complex in the root meristem, Cucurbita pepo. The results were controlled biochemically by differential and linear density gradient ultracentrifugation of extracts from normal and Triton-treated roots. The various fractions were characterized by electron microscopy or by assay of marker enzymes.
