RESUMO
BACKGROUND: Functional constipation (FC), a functional bowel disorder with symptoms of constipation, has considerable impact on quality of life. As data regarding its prevalence and epidemiology are lacking, this study aimed to evaluate the prevalence, population composition, lifestyle, quality of life, and clinical characteristics of these individuals by comparing people with and without FC. These parameters were also compared among individuals with strong and weak awareness of constipation. METHODS: An internet survey was conducted among 10,000 individuals aged 20-69 years from the general Japanese population; they were registered with an internet survey company. The following data were obtained: age, sex, educational history, occupation, residence, history of other diseases, lifestyle (including smoking/drinking habits using the Japanese Health Practice Index, medication use, symptoms of constipation according to the Rome III criteria, stool types according to the Bristol stool scale, and use of laxatives, including the place of purchase and cost per month or acceptable cost per month. The 8-item Short Form Health Survey Questionnaire was also used; FC was diagnosed based on Rome III criteria. All respondents were classified according to their awareness of constipation (i.e. strong or weak), and their characteristic features were compared. RESULTS: The data of 3000 respondents were evaluated; 262 (8.7%) had FC, which was common among older adults, women, and homemakers. FC was associated with changes in the frequency of bowel movement, sensation of incomplete or scanty evacuation, and the use of manual maneuvers; these are consequential clinical symptoms of FC. These individuals frequently skipped breakfast, had insufficient sleep, had more severe constipation, and had purchased laxatives in pharmacies or online more often than those without FC. A strong awareness of constipation was significantly more prevalent among women and homemakers. A history of anemia and cardiovascular disease was significantly more frequent in the strong awareness group, whereas a history of hypertension was more frequent in the weak awareness group. CONCLUSIONS: Appropriate and comprehensive management should be provided for FC, based on the understanding of its characteristic features and considering the symptoms and lifestyle.
RESUMO
BACKGROUND/AIMS: Our study aimed to evaluate the effect of oral litholysis in patients with chronic calcific pancreatitis (CCP) unresponsive to or ineligible for extracorporeal shock wave lithotripsy (ESWL) and endoscopic therapy. METHODS: Trimethadione, an antiepileptic agent, was administered orally at a dose of 0.6-0.9 g/day to 15 patients with this condition. Treatment outcome was evaluated by assessment of dissolution of the pancreatic stones on plain X-ray films and computed tomography scans of the upper abdomen. Plasma glucose, hemoglobin A1c, and body mass index (BMI) were also monitored throughout the therapy. RESULTS: Litholysis was observed in 13 out of 15 patients (86.7%) and was definite in 10 and partial in 3. Six patients had pancreatitis attacks during the therapy; 5 of whom showed definite litholysis and had only 1 mild attack. Of the 11 patients with normal or impaired glucose tolerance at baseline, none developed diabetes mellitus and all showed litholysis. BMI significantly increased in patients whose pancreatic stones dissolved. There was no vital organ impairment by trimethadione. CONCLUSION: Oral litholysis using trimethadione may represent a noninvasive and effective complementary treatment in patients with CCP unresponsive to or ineligible for ESWL and endoscopic therapy.
