D-tagatose is a potential new sugar substitute. Ingested D-tagatose is incompletely absorbed from the small intestine; unabsorbed D-tagatose reaches the colon where it is completely fermented. In a double-blind, controlled crossover study, the gastrointestinal effects were compared following acute consumption of 40 g plain chocolates containing 20 g of sucrose, lactitol, or D-tagatose by 50 healthy adults ages 18 to 24 years. Consumption of D-tagatose was not associated with a significant increase in the frequency of passing feces, or in the number of subjects passing watery feces. However, lactitol consumption was associated with an increase in both of these occurrences. Consumption of chocolate containing D-tagatose and lactitol resulted in significant increases in colic, flatulence, borborygmi, and bloating compared to consumption of the sucrose-containing chocolate, but the majority of symptoms were described as only "slightly more than usual." D-tagatose-containing chocolate did not provoke significantly more of these symptoms than lactitol-containing chocolate. A significant number of subjects reported nausea following consumption of D-tagatose chocolate compared to the sucrose chocolate control, and multiple symptoms occurred in some subjects. Overall, these results demonstrate that a 20-g dose of D-tagatose is tolerated well in comparison to lactitol.

A randomized, double-blind, placebo-controlled, parallel-group study was conducted to evaluate the efficacy and safety of gabapentin in relieving the symptoms of social phobia. Sixty-nine patients were randomly assigned to receive double-blind treatment with either gabapentin (dosed flexibly between 900 and 3,600 mg daily in three divided doses) or placebo for 14 weeks. A significant reduction (p < 0.05) in the symptoms of social phobia was observed among patients on gabapentin compared with those on placebo as evaluated by clinician- and patient-rated scales. Results were similar for the intent-to-treat and week-2 completer populations. Adverse events were consistent with the known side effect profile of gabapentin. Dizziness (p = 0.05), dry mouth (p = 0.05), somnolence, nausea, flatulence, and decreased libido occurred at a higher frequency among patients receiving gabapentin than among those receiving placebo. No serious adverse events or deaths were reported. On the basis of these limited data, it seems that gabapentin offers a favorable risk-benefit ratio for the treatment of patients with social phobia. Further studies are required to confirm this effect and to determine whether a dose-response relationship exists.

A multinational, multicentre, randomized, prospective, parallel-group study compared treatment with ciprofloxacin administered as an oral suspension (500 mg twice daily for 7 days) with co-amoxiclav tablets (625 mg three times daily for 7 days) in patients suffering from acute exacerbations of chronic bronchitis (AECB). A total of 147 of 165 cases treated with ciprofloxacin (89.1%) and 146 of 162 cases treated with co-amoxiclav (90.1%) were classified as being clinical successes at the primary efficacy assessment 7 days after the end of therapy (assessed as reduced cough, improvement in dyspnoea, reduction in 24-h sputum volume or reduced purulence of sputum). Treatment equivalence was statistically confirmed; treatment difference:--1.0%, 95% CI--6.6% and 4.5%. Before treatment, 128 bacterial strains were isolated from 103 patients (60 ciprofloxacin and 68 co-amoxiclav). The most commonly isolated organism was Haemophilus influenzae (60 isolates), followed by Moraxella catarrhalis (12 isolates), Streptococcus pneumoniae (11 isolates) and Staphylococcus aureus (10 isolates). At day 14, 40 of 46 ciprofloxacin-treated patients (87.0%) and 46 of 55 co-amoxiclav-treated patients (83.6%) who were valid for bacteriological analysis were classified as being bacteriological success (classed as eradication, eradication with colonization or presumed eradication; treatment difference: 3.3%, 95% CI--8.3% and 14.9%). The adverse event profile was comparable between treatment groups. Most adverse events considered possibly or probably related to study drug were related to the gastrointestinal system and were of mild or moderate severity: nausea (13% ciprofloxacin, 10.6% co-amoxiclav), flatulence (10.3% ciprofloxacin, 3.9% co-amoxiclav), abdominal pain (7.6% ciprofloxacin, 7.3% co-amoxiclav) and diarrhoea (4.3% ciprofloxacin, 6.7% co-amoxiclav). We concluded that a 7-day course of ciprofloxacin suspension is equivalent to a 7-day course of co-amoxiclav tablets in terms of clinical and bacteriological efficacy and tolerability for the treatment of AECB. Thus, ciprofloxacin suspension may offer a suitable alternative treatment for AECB patients who have difficulty in swallowing, or who prefer liquid medications to tablets.

Intramuscular (i.m.) injection with meperidine is the most common analgesic approach to treat postoperative pain in Taiwan. Hydromorphone (Dilaudid) can provide very potent and rapid analgesic effect through subcutaneous (s.c.) injection. Although hydromorphone is widely used in North America, no study has compared the analgesic efficacy, side effect profiles and patients' satisfaction with the method of injection of hydromorphone s.c. and meperidine i.m. for the immediate post-operative analgesia. In this randomized and double-blind study, 60 female patients scheduled for abdominal total hysterectomy were treated either with 1 mg hydromorphone s.c. (n = 30) or 50 mg meperidine i.m. (n = 30) when they regained consciousness and asked for analgesic treatment in the recovery room. Visual analogue score (VAS) of wound pain was obtained at 0, 10 and 30 min after injection by a blinded observer. The occurrence and severity of nausea, vomiting, dizziness, drowsiness, flatus passage and respiratory depression were recorded. Post-operative analgesia in the ward was maintained by patient-controlled analgesia (PCA) with intravenous morphine. Time to first PCA demand, the number of demands, delivery, delivery/demand ratio and 24 h morphine consumption were documented. We found that VAS was reduced at 10 min and, to a greater extent, at 30 min postinjection in both groups but with no significant difference between the two groups. The occurrence and severity of side effect profiles were similar in both groups except that dizziness was more frequently observed after meperidine injection. Delivery, demand, delivery/demand ratio and 24 hr morphine consumption by PCA were not significantly different between the two groups. Time to first PCA trigger was also similar. Patients receiving hydromorphone s.c. injection exhibited higher satisfactory score than those receiving meperidine i.m. injection. Hydromorphone 1 mg, injected subcutaneously, was as effective as intramuscular meperidine 50 mg while permitting more favorable injection technique and fewer side effects. We suggest that subcutaneous hydromorphone is a good alternative to intramuscular meperidine for postoperative analgesia in the recovery room.

Cholecystoenteric fistula is a rare complication of biliary tract diseases. The symptoms are abdominal pain, fever, nausea, vomiting, flatulence, fat intolerance, diarrhoea and weight loss. The fistula may often be asymptomatic for a long time. We report a 76-year-old woman with a cholecystocolic fistula between the gallbladder and the right flexure of the colon. The symptoms were persistent right upper quadrant pain and diarrhoea. Barium enema demonstrated the fistula. The patient was treated with an open cholecystectomy and a resection of the fistula.

Anaesthesia and surgical procedures lead to a reduction of intestinal motility, and opioids may produce a postoperative ileus, that might delay postoperative feeding. The aim of this prospective randomised study is to test whether or not different kinds of epidural analgesia (Group A: morphine 0.0017 mg/kg/h and bupivacaine 0.125%-0.058 mg/kg/h; Group B: morphine alone 0.035 mg/kg/12h in the postoperative period) allow earlier postoperative enteral feeding, enhance intestinal motility a passage of flatus and help avoid complications, such as nausea, vomiting, ileus, diarrhoea, pneumonia or other infective diseases. We included in the study 60 patients (28 males and 32 females) with a mean age of 61.2 years (range 50-70) and with an ASA score of 2 or 3. All patients had hepato-biliary-pancreatic neoplasm and were candidates for major surgery. We compared two different pharmacological approaches, i.e., morphine plus bupivacaine (30 patients, Group A) versus morphine alone (30 patients, Group B). Each medication was administered by means of a thoracic epidural catheter for the control of postoperative pain. In the postoperative course we recorded every 6 hours peristaltic activity. We also noted morbidity (pneumonia, wound sepsis) and mortality. Effective peristalsis was present in all patients in Group A within the first six postoperative hours; in Group B, after 30 hours. Six patients in Group A had bowel motions in the first postoperative day, 11 in the second day, 10 in the third day and 3 in fourth day, while in Group B none in the first day, two in the second, 7 in the third, 15 in the fourth, and 6 in the fifth: the difference between the two groups was significant (p<0.05 in 1st, 2nd, 4th and 5th days). Pneumonia occurred in 2 patients of Group A, and in 10 of Group B (p < 0.05). We conclude that epidural analgesia with morphine plus bupivacaine allowed a move rapid return to normal gut activity and early enteral nutrition compared with epidural analgesia with morphine alone.

This study explored older adults' perceptions of constipation, and the measures taken if they believed themselves to be afflicted by this condition. The paper provides an overview of the current literature surrounding laxative use, followed by a discussion of the pilot study and its findings. The objectives of the pilot study were to establish older people's definitions of the term 'constipation'; identify prescribed laxatives, over-the-counter laxatives, and home remedies used by older people to manage constipation; produce a detailed account of when these products are used; identify the older person's belief system underpinning their concepts of constipation, and their consequent use of laxative products; and produce information which will inform nursing practice, with a particular focus on nurses in community practice. People who identified themselves as being constipated were interviewed on a one to one basis. Participants shared their stories of loneliness, social isolation and anxiety related to constipation and the need to use laxatives on a daily basis, and described persistent unpleasant and often painful physical symptoms such as bloating, urges, excessive flatus, nausea and cramps, commonly associated with laxative ingestion. Nurses are challenged to work with older people within a 'wellness' framework, helping clients to maintain their bowel function, rather than fall back on short-term options, which provide only brief relief of symptoms, while ignoring the underlying causes.

Carbohydrates are hydrolyzed in the intestinal lumen by specific enzymes to monosaccharides before transport across the brush border membrane of epithelial cells into the cell interior. The enzymes implicated in the digestion of carbohydrates in the intestinal lumen are membrane-bound glycoproteins that are expressed at the apical domain of the enterocytes. Absent or reduced activity of one of these enzymes is the cause of disaccharide intolerance and malabsorption, the symptoms of which are abdominal pain, cramps or distention, flatulence, nausea and osmotic diarrhea. Lactose intolerance is the most common intestinal disorder that is associated with an absence or drastically reduced levels of an intestinal enzyme, in this case lactase-phlorizin hydrolase (LPH). The pattern of reduction of activity has been termed late onset of lactase deficiency or adult type hypolactasia. It was thought that the regulation of LPH was post-translational and was associated with altered structural features of the enzyme. Recent studies, however, suggest that the major mechanism of regulation of LPH is transcriptional. Other forms of lactose intolerance include the rare congenital lactase deficiency and secondary forms, such as those caused by mucosal injury, due to infectious gastroenteritis, celiac disease, parasitic infection, drug-induced enteritis and Crohn's disease. This review will shed light on important strucural and biosynthetic aspects of LPH, the role played by particular regions of the LPH protein in its transport, polarized sorting, and function, as well as on the gene expession and regulation of the activity of the enzyme.

To evaluate the glycemic response to a food starch esterified by 1-octenyl succinic anhydride (OSA), 30 healthy nondiabetic adult subjects were studied in a double-blind crossover design. After an overnight fast, subjects consumed a product containing either 25 g of glucose or 25 g of OSA-substituted starch. Finger-prick capillary blood was obtained at baseline and 15, 30, 45, 60, 90, and 120 min postprandial for glucose measurement. After OSA treatment, the rise in blood glucose was reduced (P < 0.05) at 15 and 30 min and tended (P < 0.08) to be lower at 45 min. Mean peak rise in glucose was reduced 19% (P < 0.01) by OSA (3.30 +/- 0.19 versus 2.66 +/- 0.16 mmol/L) compared to glucose, but time to peak did not differ between treatments. Net incremental area under the curve was also lower (P < 0.05) on OSA compared to glucose. Minimal effects on gastrointestinal symptoms (intensity and frequency of nausea, cramping, distention, and flatulence) were noted for both products, with no clinically significant difference between products. In conclusion, starch substitution with OSA attenuated the postprandial glycemic excursion compared to an equivalent glucose challenge and was well tolerated by fasting healthy adult subjects.

There is considerable evidence to support an immunopathogenic basis of psoriasis. However, changes such as altered angiogenesis have also been implicated in the pathogenesis of psoriasis. AE-941 (Neovastat; Aeterna Laboratories, Quebec City Quebec, Canada) is a naturally occurring product currently in clinical investigation that blocks two main mechanisms of angiogenesis activation, namely, vascular endothelial growth factor and matrix metalloproteinase. We hypothesized that psoriasis could be modulated by inhibiting the neovascularization of psoriatic plaques. We conducted a randomized dose-comparison trial to evaluate the safety and potential therapeutic benefit of AE-941, administered orally to patients with psoriasis. Forty-nine patients with psoriasis were enrolled and assigned to receive AE-941 at 30, 60, 120, or 240 mL/d for 12 weeks. Patients were followed up for another 12-week period. Improvement in the Psoriasis Area and Severity Index (PASI) score was observed in 50%, 41.7%, and 30.8% of the patients receiving 240, 120, and 60 mL/d, respectively. No patients receiving a dosage 30 mL/d showed a PASI score improvement. A statistically significant improvement with increasing dose was observed for the PASI score, severity of itch, and the physician's global assessment. The most commonly reported nonserious drug-related adverse events affected the gastrointestinal system in 12 of 49 patients (primarily nausea, diarrhea, vomiting, flatulence, and constipation) and the skin and appendages in 4 of 49 patients (primarily acne and rash). This randomized phase I/II study provides evidence that the antiangiogenic agent AE-941 offers a new therapeutic approach to the management of psoriasis.
