Effect of wheat bran in treatment of chronic nonorganic constipation. A double-blind controlled trial.

After a two-week basal period, 24 patients were randomly allocated to receive, with a crossover double-blind design, for two consecutive four-week periods, bran (20 g/24 hr) or placebo. The daily intake of water and dietary fibers was standardized. Symptomatology, oroanal transit time, bowel frequency, and stool weight were assessed in basal conditions and at week 4 and 8 of the treatment. Oroanal transit time decreased and bowel frequency and stool weight increased significantly during both bran and placebo administration in comparison with basal period. Bran treatment was more effective than placebo in improving bowel frequency and oroanal transit. During bran treatment oroanal transit time became normal only in patients with slow colonic transit and not in those with slow rectal transit. Neither the occurrence nor the severity of the most frequent accompanying symptoms of chronic constipation differed significantly between placebo and bran treatments.

[The diagnostic-therapeutic approach to hypertension. A study of 1000 Italian physicians].

A survey was made on a sample of Italian practitioners to evaluate the diagnostic and therapeutic approach to arterial hypertension. A questionnaire was distributed containing thirteen questions, that was personally completed and restituted by 919 physicians. The first datum that was evidenced was that the hypertensive patient observed by the practitioner is, in the great majority of cases, in old age. The percentage of patients with concomitant diseases (dyslipidemia, diabetes, obesity, cardiac failure) is very high. The blood pressure measurement is correct, especially by expert physicians. By contrast, the younger physicians tend to prescribe further diagnostic instrumental measures. The antihypertensive therapy is prescribed very accurately. According to the sample studied, the first line drugs that are more often recommended are the ACE-inhibitors, especially by younger physicians. From this survey a prualently positive judgment by the physicians emerged in relation to the available drugs for the anti-hypertensive therapy, as consequence of the observation of satisfactory therapeutic efficacy and tolerability by the patients.

Rectal sensitivity in chronic constipation.

Rectal sensitivity is often reduced in patients affected by chronic constipation, but it is not known whether this alteration differs according to the severity and the site(s) of the slowing of gastrointestinal transit. Moreover, it is not known whether alteration precedes or follows bowel complaints. In this study, perception of intrarectal distension was evaluated in 28 healthy controls, in 20 patients complaining of constipation and with a normal gastrointestinal transit time (less than 96 hr), and in 44 patients complaining of constipation and with a prolonged gastrointestinal transit time (greater than 96 hr). Within the latter group, perception to intrarectal distension was analyzed in patients with slowing of transit in the rectum only, in the colon only, and in both the rectum and the colon. In a subgroup of 22 patients, rectal sensitivity was evaluated before and after treatment. Rectal sensitivity was found to be reduced significantly in constipated patients; it was more severely reduced in patients with objective evidence of prolonged gastrointestinal transit time and with slow transit in the rectum. Rectal sensitivity improved in patients who responded to treatment and did not vary significantly in nonresponders.

Large-bowel transit in paraplegic patients.

Severe constipation often follows spinal cord injury. The aim of this study was to evaluate transit of contents through the large bowel in patients with paraplegia after a complete transverse lesion of the spinal cord. Transit through the right colon, left colon, and rectum was evaluated in 11 patients (eight males, 3 females; 17 to 63 years old) and data were compared with that of 37 healthy control subjects. In all patients there was either no, or abnormally low, transit at the level of the left colon and rectum. A minor degree of transit delay at the level of the right colon was also present in eight patients. These data indicate that constipation in patients with paraplegia is due to abnormal transit, mainly at the level of the left colon and rectum, and transection of the spine between the C-4 and T-12 vertebral levels causes alteration of large-bowel motor activity mainly at the level of the segments innervated by the parasympathetic fibers of the sacral outflow.

Laxative consumption in chronic nonorganic constipation.

We looked at laxative consumption and its relationship to bowel habits, total gastrointestinal transit time (TGITT), and symptoms in patients with chronic nonorganic constipation. Of the patients, 87.9% used laxative, 30% habitually. Laxative intake increased with age, so that habitual consumption was more frequent in patients with long-standing (greater than 10 years) constipation. Although habitual laxative users had a consistent trend toward lower bowel frequency and prolonged TGITT, no relationship was found among intake and observed bowel frequency, TGITT, or large bowel segmental transit time. Although laxatives induced more satisfactory or less difficult evacuations, they also caused diarrhea and mucus in the stool. Laxative consumption did not bring about any detectable improvement in the abdominal or extraabdominal symptoms usually associated with constipation.

Melanosis of the rectum in patients with chronic constipation.

In patients with constipation the prevalence of melanosis in rectal biopsies was evaluated in an attempt to correlate its occurrence with laxative consumption and intestinal stasis. Melanosis was present in 58 percent of the patients and in none of a control group. Melanosis was present in 73.4 percent of patients consuming anthracene laxatives and in 26.6 percent of those not consuming anthracene laxatives (P less than 0.01). No correlation was found between the occurrence (and grading) of melanosis and pattern of transit through the large bowel, bowel movements, and duration of symptoms. Results of this study seem to indicate that intestinal stasis is not a cause of melanosis of the colon and rectum and confirm that melanosis may well be due only to the consumption of anthracene laxatives; melanosis coli does not appear to be a sensitive marker of impairment of motor function in the "cathartic colon."
