Abstract
OBJECTIVE Gastrointestinal (GI) uptake of 2-[18F]-fluoro-2-deoxy-D-glucose (FDG) is frequently observed in whole-body positron emission tomography (PET) images. Such physiological uptake may interfere with accurate interpretation. The aim of the present study was to determine whether physiological gastrointestinal FDG uptake can be decreased by means of an antiperistaltic agent, N-butylscopolamine, or a gastric secretion inhibitor, omeprazole. METHODS Sprague-Dawley rats were divided into three groups: omeprazole-treated (n = 6), N-butylscopolamine-treated (n = 7), and control group (n = 6). The rats in the omeprazole-treated group were administered omeprazole (1.0 mg/kg) intravenously 45 minutes before FDG injection. The rats in the N-butylscopolamine-treated group were administered N-butylscopolamine (1.0 mg/kg) intramuscularly 10 minutes before FDG injection. Sixty minutes after FDG injection under overnight fasting state, the gastrointestinal tissues were excised and weighed to determine the radioactivity of 18F using a gamma counter. RESULTS The mean values of FDG uptake in the esophagus, stomach, small intestine, cecum and colon of the N-butylscopolamine-treated group vs. the omeprazole-treated group were 148% vs. 162%, 109% vs. 113%, 113% vs. 88%, 102% vs. 85%, 105% vs. 70% of the control group, respectively. There were no statistical differences in FDG uptake rate in the esophagus, stomach, or cecum among the three groups. FDG uptake rates in the small intestine and colon of the omeprazole-treated group were significantly lower than those in the control group. CONCLUSION Physiological FDG uptake in the GI tract was not decreased by the administration of N-butylscopolamine. Omeprazole was effective in decreasing FDG uptake in the small intestine and colon. Omeprazole has a potential to decrease FDG uptake rate in a limited part of the GI tract.

Abstract
BACKGROUND AND STUDY AIMS There is wide variation in the use of antispasmodics to facilitate colonoscopy, both within and between countries, and its use before such procedures remains controversial. The aim of this study was to determine whether there was any objective benefit in using hyoscine as a premedication for colonoscopy in a district general hospital. PATIENTS AND METHODS Consecutive day-case patients undergoing colonoscopy were included in the study. They were prospectively randomly allocated to receive either intravenous hyoscine (n = 61) or intravenous placebo (n = 56) as part of their premedication. RESULTS Our analysis demonstrated no statistically significant difference between the two groups with respect to the median time from colonoscope insertion to caecal intubation (9.7 minutes in the hyoscine group vs. 8.3 minutes in the placebo group) or the median total procedure time (14.8 minutes in the hyoscine group vs. 13.8 minutes in the placebo group). There was also no statistically significant difference in success rates for caecal intubation between the two groups ( P < 0.06). However a type II error cannot be excluded because of the small sample size. CONCLUSION This study demonstrated no obvious benefit in the routine use of hyoscine as a premedication for colonoscopy in a district general hospital setting.

Abstract
PURPOSE To determine the practicality of MRI using a new real-time sequence for the assessment of gastric motion, and quantify the effects of motility-modifying substances. MATERIALS AND METHODS Six healthy volunteers ingested 400 mL of a high-calorie liquid nutrient. Two-dimensional real-time TrueFISP sequences were acquired for up to 30 minutes following the ingestion. The acquisition plane was chosen parallel to the axis of the gastric antrum. The examination was performed on three separate days with and without i.v. administration of 10 mg metoclopramide or 20 mg scopolamine. A motility index was calculated for each real-time data set. RESULTS Delineation of the gastric lumen proved easy and robust. The intravenous application of motility-modifying agents resulted in significant changes in the motility index. The administration of metoclopramide resulted in an average increase of the index by a factor of 1.5, whereas the application of scopolamine led to a decrease of the index by a factor of 3.0. CONCLUSION TrueFISP MRI performed well in depicting the gastric lumen and assessing gastric motility. Furthermore, we were able to evaluate and quantify the effect of motility-modifying agents. The noninvasive nature of MRI makes this imaging modality an attractive alternative to conventional invasive diagnostic tools for gastric motility disorders and monitoring of therapy.

Abstract
OBJECTIVES Evaluate the safety and effectiveness of quinacrine for non-surgical female sterilization in five different protocols. METHODS The 5 trials were conducted sequentially. The first and largest, with 985 cases, tested the use of a curved inserter to place a 50 mg dose of quinacrine near each tubal ostia. The next 3 trials were carried out to determine the effect of adjunct procedures on the efficacy of the standard recommended protocol. The three adjuncts were 75 mg of intrauterine diclofenac, 10 mg medroxyprogesterone IM and either 10 mg of atropine IM or 20 mg of hyoscine butylbromide IM The final trial focused on the currently recommended protocol. RESULTS The 100 mg dose placed at the tubal ostia with the curved inserter resulted in a failure rate of 9.0% at 20 years. Diclofenac or medroxyprogesterone did not improve efficacy over quinacrine alone. Atropine or hyoscine butylbromide substantially diminished the effectiveness of the quinacrine. The failure rate with the standard protocol in our series of 122 cases was 0.8% at 3.5 years. Side effects were minor. There were no deaths nor serious complications with any of these protocols. DISCUSSION All 5 protocols appeared to be safe and the standard one was the most effective.

Abstract
The aim of this study was to examine the efficacy of IV Buscopan as a muscle relaxant in CT colonography in terms of colonic distension and polyp detection, and to determine its particular efficacy in patients with diverticular disease. Seventy-three consecutive patients were randomised to receive IV Buscopan or no muscle relaxant prior to CT colonography. CT colonography was performed using a Siemens Somatom 4-detector multislice CT scanner. The following parameters were recorded: degree of colonic distension using a 4-point scale; diagnostic adequacy of colonic distension; presence or absence of diverticular disease; and presence of colonic polyps. Accuracy of polyp detection was assessed using subsequent conventional colonoscopy as a gold standard. There was no significant difference between the two groups in the number of segments that were deemed to be optimally or adequately distended (p=0.37). Although IV Buscopan did improve distension of certain segments, this effect was not sufficient to improve the number of diagnostically adequate studies in the Buscopan group (p=0.14). In patients with diverticular disease, IV Buscopan did not have any significant effect on segments affected by diverticulosis but was associated with an improvement in distension of more proximal segments. There was no significant difference between the two groups in terms of polyp detection (p=0.34). The addition of prone scanning to supine scanning was found to be the most useful technique for maximising colonic distension. Intravenous Buscopan at CT colonography does not improve the overall adequacy of colonic distension nor the accuracy of polyp detection. In patients with sigmoid diverticular disease IV Buscopan improves distension of more proximal colonic segments and may be useful in selected cases, but our results do not support its routine use for CT colonography.

Abstract
The administration of drugs by s.c. infusion is routinely practiced in palliative medicine for the management of patients who are no longer able to take oral medication. It is not uncommon for two or more drugs to be combined in s.c. infusion solutions. Unfortunately, the compatibility and stability of haloperidol and hyoscine- N-butyl bromide has not yet been determined. The objective of this study was to study the compatibility and stability of solutions containing both drugs in polypropylene syringes. Nine different solutions were assessed for up to 15 days following preparation. The solutions were prepared in polypropylene syringes with 0.9% saline as a diluent and stored at 4 degrees C and 25 degrees C. High-performance liquid chromatography was the analytical technique used to measure haloperidol and hyoscine- N-butyl bromide. The initial concentration ranges were 0.3125-1.25 mg/ml for haloperidol and 2.5-10.0 mg/ml for hyoscine- N-butyl bromide. Haloperidol was precipitated at a concentration of >/=1.25 mg/ml when it was combined with hyoscine- N-butyl bromide. Concentrations of hyoscine- N-butyl bromide lower than 10 mg/ml in mixtures with haloperidol or 0.625 mg/ml of haloperidol in mixtures with hyoscine- N-butyl bromide for s.c. infusion allow for the administration of both drugs without any significant loss after storage at 25 degrees C for periods of up to 15 days, with approximately >/=90% and 88%, respectively, of haloperidol and hyoscine- N-butyl bromide remaining. However, after storage of the mixtures for equivalent periods at 4 degrees C the losses of hyoscine- N-butyl bromide observed at the end of the study were higher than 20%, while the percentages of haloperidol remaining after 15 days at this temperature were >/=94.37%.

Abstract
In abdominal MR imaging, ghost artifacts from noncyclic bowel movements can reduce the quality of the images. Although pharmacologic suppression of motion is effective, no study has being conducted to analyze the influence of drug motion suppression on fast breath-hold 1.5-T examinations of the upper abdomen. A prospective, randomized, double-blind trial was conducted in 50 patients. Patients were randomly distributed into two groups: The control group received only an oral solution, whereas the other group received the oral solution plus a subcutaneous injection of 20 mg of butylscopolamine 10 min before the MR examination. Breath-hold T1-weighted gradient-recalled-echo (GRE) MR images were obtained in a 1.5-T superconductive unit. Quantitative image analysis was performed with region-of-interest (ROI) measurements of the signal intensity of the liver and in background air anterior and lateral to the patient. A qualitative analysis of the subjective quality of the T1-weighted images was also done, and the adverse reactions were registered. The groups were homogeneous regarding age, gender, and weight distribution. No significant differences in the signal intensity of the liver and in the incoherent noise measurements were found between the two groups. Gastrointestinal noise showed significant differences between groups, with lower values for the butylscopolamine group compared with the control group. There was also a statistically significant difference in the image quality between groups, and optimal studies were only found in the butylscopolamine group, where most patients had a good-quality evaluation. Regarding adverse events, there were non-significant differences between groups. In conclusion, administration of an antiperistaltic agent to reduce the movements of the gastrointestinal tract diminishes the motion artifacts generated on MR imaging of the abdomen, even at high field strength and with fast imaging sequences. Images of the upper abdomen obtained after pharmacologic suppression of the gastrointestinal movement are of significantly superior quality.

Abstract
BACKGROUND Many drugs have been utilized for the treatment of renal colic, but to date no drugs that relieve pain quickly and completely have been developed. Thus, we conducted a prospective trial to evaluate the effects of trigger point injection on renal colic. In this study, we used a local injection of lidocaine to the trigger point of patients experiencing renal colic, and evaluated the efficacy in patients using the visual analog scale. METHODS Sixty patients with renal colic were enrolled in this study and divided into two groups by a simple randomization: (i) the butylscopolamine group (n = 30, intravenous injection of butylscopolamine bromide and sulpyrine); and (ii) the lidocaine group (n = 30, local anesthesia to the trigger point with lidocaine). RESULTS Renal colic had disappeared completely at the end of the trigger point injection in 15/30 patients and the average time required to produce a 50% improvement in symptoms was 9 min in all patients in the group. In the lidocaine group, only one patient needed an additional anodyne treatment after 60 min and none of the 29 patients whose pain disappeared within 60 min needed further anodyne treatment within 24 h. These results were all significantly superior to those of the conventional treatment. No side-effects and complications were observed. CONCLUSION Trigger point injection, in our experience, is an easy, safe and effective method for the amelioration of renal colic. It was significantly superior to the combination of intravenous butylscopolamine and sulpyrine.

Abstract
PURPOSE The purpose of our study was to assess the diagnostic potential of helical CT-enteroclysis (HCTE) and to correlate our findings to endoscopic and surgical results. METHODS Twenty-eight consecutive patients suffering from histologic proven Crohn disease underwent HCTE and endoscopy within 4 weeks. HCTE findings were read by two observers in consensus and compared with endoscopic and surgical results. RESULTS Morphological signs of an acute or recurrent bowel inflammation were found in 25 of 28 (89%) patients. HCTE demonstrated accurately all mural and extramural changes of the inflamed bowel walls. Moreover, in 18 of 25 (72%) patients, HCTE depicted additional pathologic changes such as fistulas, abscesses, and skip lesions, all of which could not be visualized by endoscopy. CONCLUSION HCTE is an accurate technique to detect mural and extramural abnormalities in patients with Crohn disease. HCTE should be considered as a complementary imaging method to endoscopy, and should be the first imaging method especially when Crohn-associated complications are suspected.

Abstract
BACKGROUND AND STUDY AIMS Colonoscopy is generally perceived as being a painful procedure. Contributory factors are: stretching of the colonic wall and mesenteric attachments from looping of the instrument shaft, overinsufflation, the degree of torque or force applied to the colonoscope shaft, and patient pain threshold. The aim of this study was to determine the frequency of pain episodes experienced during diagnostic colonoscopy and the corresponding colonoscope configuration, utilizing real-time magnetic endoscope imaging (MEI). PATIENTS AND METHODS Consecutive outpatients undergoing colonoscopy were studied. Patients with previous colonic resections were excluded. Procedures were commenced with antispasmodics only, and patient sedation was self-administered whenever significant discomfort was experienced, using a patient-controlled analgesia (PCA) syringe pump. All "demands" were correlated with the MEI record, which was subsequently analysed. RESULTS A total of 650 demands were recorded in 102 patients. Seventy-seven percent of all demands occurred with the colonoscope tip in the sigmoid colon, 7 % in the descending colon, 6 % at the splenic flexure, 5 % in the transverse colon, and 4 % in the proximal colon. Ninety percent of all pain episodes coincided with either looping (79 %) or straightening of the colonoscope shaft (11 %); presumed overinsufflation being an infrequent cause of pain (9 %). Of the loops encountered during colonoscopy, the N-sigmoid spiral loop was associated with the majority of pain episodes (56 %). Looping was both more frequent ( P = 0.0002) and less well tolerated in women than in men ( P = 0.0140). CONCLUSIONS This study is the first to document pain at colonoscopy accurately. Looping, particularly in the variable anatomy of the sigmoid colon, is the major cause of pain, especially in women. Use of MEI may improve pain control by facilitating the straightening of loops within the sigmoid colon, and by enabling the endoscopist to target patient analgesia.

Abstract
The objectives of this study were first to investigate the compatibility and physical stability of drug admixtures destined for s.c. administration through elastomeric infusion pumps to terminally ill cancer patients followed up at home by staff of the Palliative Care Unit (AECC), "La Paz" Hospital, Madrid and secondly, to evaluate the local side-effects related to the infusion of some of the drug mixtures to a population of 50 patients. The drug mixtures prepared included combinations of two, three, four and five of the following drugs: morphine hydrochloride, 60 mg/day; midazolam hydrochloride, 15 mg/day; haloperidol lactate, 7.5 mg/day; hyoscine-N-butyl-bromide, 60 mg/day; dexamethasone sodium phosphate, 16 mg/day; metoclopramide hydrochloride, 40 mg/day, and tramadol, 400 mg/day. Out of 86 mixtures evaluated in vitro, 52 were found to be physically compatible. Precipitation was always obtained when dexamethasone sodium phosphate at the concentrations assayed was combined with haloperidol lactate and/or midazolam hydrochloride. However, no precipitation occurred when morphine hydrochloride, the opioid most frequently used in patients of this type, and dexamethasone sodium phosphate were combined. Of the drug mixtures that were physically compatible, 18 were administered to the patient population evaluated. Very good symptom control was obtained with all of them, and especially with the mixture of morphine + midazolam + haloperidol + hyoscine, which is the one most frequently administered to cancer patients for palliative care in the final stages of life in our Unit.

Abstract
BACKGROUND Glucagon inhibits digestive motility and is used for endoscopic premedication; however, its effect on cardiopulmonary function during endoscopy has not yet been fully investigated. AIM To clarify the efficacy and safety of glucagon compared with butyl scopolamine bromide as upper gastrointestinal endoscopy premedication. METHODS Two hundred and forty consecutive patients over 40 years of age, referred for upper gastrointestinal endoscopy, without any complications, were studied. These patients were randomly premedicated with butyl scopolamine bromide (SC group) or glucagon (G group). Time course changes in blood pressure, arterial oxygen saturation, heart rate and the number of retching episodes during endoscopy were examined. The efficacy of glucose tablets after upper gastrointestinal endoscopy to prevent hypoglycaemia caused by glucagon was evaluated. Cardiopulmonary parameters were also examined in 77 complicated patients with glucagon premedication (GC group). RESULTS A continuous increase in heart rate during upper gastrointestinal endoscopy was observed in the SC group, but not in the G and GC groups. Blood pressure, arterial oxygen saturation and number of retching episodes were not different between the groups. Hypoglycaemia-related symptoms were frequent in the G group without glucose tablets, but were prevented by the administration of glucose. CONCLUSIONS Glucagon has a weaker effect on cardiopulmonary function during upper gastrointestinal endoscopy than butyl scopolamine bromide. Glucose administration prevents hypoglycaemia-related symptoms caused by glucagon.

Abstract
The effects of pretreatment with the gastrointestinal stimulant domperidone and the suppressant scopolamine butylbromide on the absorption of AS-924, a novel prodrug-type cephem antibiotic, were investigated in six healthy adult male volunteers by a cross-over method. The T(max) of ceftizoxime (CTIZ), the active moiety of AS-924, was slightly prolonged by scopolamine butylbromide (T(max)=1.8 vs. 1.5 h for the group without pretreatment). However, there were no significant differences in pharmacokinetic parameters including T(max), cumulative urinary excretion rates of CTIZ and cumulative urinary excretion rates of pivaloylcarnitine for 12 h after the dosing between the pretreated and control groups. Domperidone did not affect the absorption of AS-924.

Abstract
AIM To determine whether the timing of buscopan administration during double-contrast barium enema examination (DCBE) affects diagnostic quality. MATERIALS AND METHODS In a prospective setting, 100 consecutive adult out-patients referred for DCBE received 20 mg buscopan (hyoscine-N-butylbromide) intravenously, either before infusion of barium suspension (Group A) or after barium infusion and gas insufflation (Group B). A subjective assessment of ease of contrast medium infusion was made at the time of examination and the films subsequently analysed by two radiologists unaware of the mode of relaxant administration, who noted the quality of mucosal coating and made subjective and objective measurements of segmental distension. RESULTS There was no significant difference in screening times, infusion difficulty or colonic contrast medium coating between the two groups. Subjective assessment of distension of the caecum, ascending colon, transverse colon and rectum were not significantly different. Patients receiving intravenous relaxant after barium and gas infusion had less subjective descending (P = 0. 05) and sigmoid (P = 0.04) colon distension, but there was no significant difference with respect to maximal bowel diameter in any of the segments measured. CONCLUSION The timing of intravenous administration during DCBE is likely to have no significant effect on the diagnostic quality of the study.

Abstract
PURPOSE To improve the image quality of magnetic resonance cholangiopancreatography (MRCP) by modification of examination conditions. MATERIALS AND METHODS MRCP of 72 patients was performed with a 1.5 T system (Magnetom Vision, Siemens, 25 mT/m) using two breath-hold techniques, half-fourier acquisition with multislice T2-WI HASTE in MIP technique, and single shot T2-WI turbo-spin-echo (RARE) with different slice thicknesses. The effects of n-butylscopolamine were assessed. Furthermore, oral contrast agents [barium sulfate, Fe(II)-gluconate, Fe(II,III)-oxide] in various concentrations were used. The slice thickness was varied for the RARE sequence (3-7 cm). RESULTS N-butylscopolamine had no influence on image quality. Improvements could be attained by variation of the slice thickness. A significant reduction of disturbing background noise was obtained by oral application of iron gluconate, or iron oxide-containing contrast media. Similar improvements were achieved with barium sulfate. CONCLUSIONS Variation of slice thickness allows an improvement of MRCP quality. Oral contrast media improve the image quality of MRCP. The expense of contrast media may be a determinant of choice.

Abstract
PURPOSE Hyoscine-N-butylbromide (HB) is an anticholinergic drug used in digital subtraction angiography of the aortoiliac region because it decreases bowel gas movement artifact. HB also causes an increase in heart rate. We investigated whether this could cause silent myocardial ischemia (SMI) in susceptible patients during peripheral angiography. METHODS Thirty-six patients undergoing peripheral angiography were randomized into two groups, with 17 patients receiving 20 mg HB intraarterially during the angiogram and 19 patients receiving no drug. All patients were fitted with a Holter monitor that recorded the electrocardiogram before, during, and after the angiogram. Heart rate trends and ST segments were then analyzed. RESULTS Patients given HB had a statistically significant rise in heart rate compared with the control group. Although the difference was not statistically significant, two (12%) patients receiving HB had procedural ST depression compared with none in the control group. Pre- and postprocedural episodes of ST depression were common, occurring in 41% of patients receiving HB and 37% of patients receiving no drug, and were associated with an increase in heart rate. CONCLUSION The infrequent episodes of procedural SMI, potentially caused by the positive chronotropic effects of HB, are probably insignificant when compared with the high frequency of SMI episodes occurring outside the procedure.

Abstract
Mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade lymphoma that differs from high-grade non-Hodgkin lymphoma both clinically and histologically. The CT appearances of MALT lymphoma are described. Of 40 patients referred with biopsy-proven MALT lymphoma, only seven had not had gastrectomy or chemotherapy prior to CT examination. The CT scans of these seven cases were analysed for the degree and extent of gastric wall thickening, enlargement of abdominal and extra-abdominal lymph nodes, and presence of extra-nodal disease. In all patients the stomach was distended with oral contrast medium and scans performed at narrow collimation, after intravenous administration of 20 mg hyoscine butylbromide. In six patients focal thickening of the gastric wall was 1 cm or less. One patient had thickening of over 4 cm. There was no enlargement of abdominal or extra-abdominal lymph nodes or extension to adjacent organs. Thus on CT, at presentation, MALT lymphoma results in minimal gastric wall thickening, unlike high-grade non-Hodgkin lymphoma, which typically causes bulky gastric disease, nodal enlargement and extension into adjacent organs. CT is therefore of limited value in monitoring response to treatment. With disease greater than minimal thickening, transformation to a higher grade should be considered.

Abstract
PURPOSE We studied the motility of orthotopic bladder substitution with stomach (gastric pouch) in adults with bladder cancer and the effect of oral intake as measured on urodynamics. We also investigated the probable relationship between continence and sensitivity of the proximal urethra. Anticholinergic medication effects on pouch motility were tested. MATERIALS AND METHODS Six patients with a gastric pouch were questioned about quality of life 6 to 43 months after surgery, and examined urodynamically before and after oral intake. During the examination the proximal urethra (directly under the anastomosis between the pouch and urethra) was electrically stimulated to determine sensitivity. We tried to inhibit the peristaltic contractions with 20 mg. butylscopolamine intravenously. RESULTS The main difference before and after oral intake was the onset time of peristaltic contractions. After eating the contractions began at a lower filling volume, which was statistically significant. There were no or insignificant differences in capacity and urodynamic parameters. We were successful in inhibiting the peristaltic contractions with anticholinergic medication. CONCLUSIONS The gastric pouch is a valuable bladder substitute with sufficient volume, antireflux characteristics, satisfactory continence rate and adequate voiding behavior. Oral intake causes motor activity of the gastric pouch at a lower fill volume than fasting during urodynamic investigation. Anticholinergic medication may be useful for inhibiting peristalsis in the gastric pouch.

Abstract
This was conducted to evaluate the analgesic effect of intravenous tenoxicam (non-steroidal anti-inflammatory drug) in the treatment of biliary colic pain and compared with spasmolytics. Thirtytwo patients (26 women, 6 men, mean age 47, range 38-55 years) with acute biliary colic were entered for study. They were allocated randomly to receive either tenoxicam 20 mg i.v. or hyoscine N-butylbromide 20 mg i.v. The patients recorded their pain severity on 5 point scale. The results showed that tenoxicam caused significant pain relief in 10 out of 16 patients at 30 min (mean pain score decreased from 2.75 +/- 0.93 to 0.49 +/- 0.51, p < 0.05) and in other 4 patients at 60 min (mean pain score decreased to 0.58 + 5.7, p < 0.05). None of these patients developed acute cholecystitis or pain relapse over a period of 24 h follow up. With use of hyoscine N-butylbromide, 7 out 16 patients had significant pain relief at 30 min (mean pain score decreased from 2.62 +/- 1.01 to 0.57 +/- 0.53, p < 0.05) and 3 other patients relieved at 60 min (mean pain score decreased to 0.66 +/- 0.57, p < 0.05). Four patients showed pain relapse within 24 h and needed pethidine-rescue treatment, two of them developed acute cholecystitis. Three out of 6 patients who showed no response to hyoscine N-butylbropmide and treated with 100 mg pethidine progressed to acute cholecystitis. We concluded that intravenous tenoxicam has rapid and prolong analgesic effects in the treatment of acute biliary colic as compared to hyoscine N-butylbroimde and it prevents the progression to acute cholecystitis.

Abstract
The aim of this study was to compare the effects of a genetically engineered glucagon (geG) and hyoscine N-butylbromide (HBB) on the quality of double-contrast barium meal (DCBM) study. Two hundred sixty-four patients scheduled for DCBM were randomized to receive intravenously geG 0.25 mg (geG-25), or geG 0.5 mg (geG-50), or HBB 20 mg as hypotonic agent. The evaluation concerned: duration of isolated visualization of the stomach (A); gastric mucosal coating (B); visualization of areae gastricae (C); quality of duodenal cap (D) and loop (E) study; delay, if any, of duodenal study (F). Global significant differences (P from 0.0183 to < 0.0001) were found for A, C, D, and F. GeG-50 allowed the longest isolated gastric visualization (P < 0.0001); geG-25 allowed more extensive visualization of areae gastricae than HBB (P = 0.0006); HBB allowed a better study of duodenal cap (P = 0.0052) and loop (P = 0.0190) than geG-25; geG-50 prolonged the examination time (P < 0.01). No adverse effect was observed with geG within 1 h after DCBM. In conclusion, geG can be safely used as a hypotonic agent in DCBM. When DCBM is focused on the stomach, 0.25 mg of geG is the optimal choice; if DCBM is focused on the duodenum, 0.5 mg of geG (with a prolonged examination time) or 20 mg of HBB (with a less effective study of the stomach) should be used.

Abstract
The purpose of this longitudinal open but not comparative study was to confirm the safety and efficacy of Lysine clonixinate (125 mg) and hyoscinbutylbromide (10 mg) capsules, during a period of observation of there menstrual cycles on 30 women with uterine dysfunction due to primary or secondary dysmenorrhea. The time of evolution for primary dysmenorrhea was of 4.46 years, and for secondary was of 1.77 years. Some associated manifestations of dysmenorrhea were: nausea (92%), vomit (92%), general pain (82.1%), abdominal pain (85.7%) and headache (46.4%). Regarding to the menstrual pain intensity, at first was highly severe in 10.7% severe in 42.9%, and moderate in 46.4%. At the end of the study, only 1 of 28 patients showed menstrual pain of moderate intensity. Only three adverse effects of light intensity were found without needing treatment, related to the manifestations of gastralgia and sleepiness. The association of a spasmolytic analgesic (Lysine clonixinate and hyoscinbutylbromide bromide) on the treatment for primary or secondary dysmenorrhea, reduces and prevents the menstrual pain (colic) as well as the associated manifestations with few spasmolytic association is efficacy and safety.

Abstract
A double-blind study was conducted to evaluate the efficacy, safety and usefulness of cimetropium bromide (DA3177) in the patients with pain caused by upper urinary calculus at a daily dose of 75 mg t.i.d. (Group D, 97 patients) in comparison with scopolamine butylbromide at a daily dose of 60 mg t.i.d. (Group B, 101 patients). According to patient's impression, the rate of "moderately improved" or better was significantly higher in Group D (68.7%) than in Group B (53.5%; Wilcoxon 2 sample test: p = 0.0044). For pain, the rate of "moderately improved" or better was 69.1% in Group D and 60.4% in Group B. In global improvement, the rate of "moderately improved" or better was significantly higher in Group D (70.1%) than in Group B (61.4%; Wilcoxon 2 sample test: p = 0.0469). The rate of "no problem in safety" showed no significant difference between Group D (91.5%) and Group B (93.3%). Adverse reactions occurred in 8.5% in Group D and 6.7% in Group B. The major adverse reactions were "dry mouth", "abdominal distension", "constipation" and "nausea". The rate of "useful" or better was 68.7% in Group D, and 60.4% in Group B. In conclusion, DA3177 was confirmed to be a useful drug for patient with pain caused by upper urinary calculus.

Abstract
PURPOSE The purpose of this article was to assess the impact of intravenous (IV) anticholinergic hyoscine butylbromide in abdominal magnetic resonance (MR) imaging with oral magnetic particles (OMP) [ABDOS-CAN, Ferristene (USAN), Nycomed Imaging AS, Oslo, Norway]. MATERIALS AND METHODS In 31 patients with abdominal tumors, T1-weighted spin-echo (SE) images (SE 600/ 15; 1.5 T) were obtained without and with IV hyoscine butylbromide (20 mg) before and after administration of 800 ml of OMP. Two blinded readers assessed motion artifacts, bowel-wall visualization, and lesion delineation on the four sets of T1-weighted images. The two-tailed Wilcoxon paired sample test was used for statistical analysis (p < .05). RESULTS Hyoscine butylbromide reduced motion artifacts and improved bowel-wall visualization on precontrast and OMP-enhanced images at a statistically significant level (p = 0.0006-0.037). The lowest degree of artifacts was recorded on OMP images with hyoscine butylbromide. OMP with hyoscine butylbromide significantly improved lesion delineation compared to studies without antiperistaltic drug before (p = 0.019) and after OMP administration (p = 0.01). CONCLUSIONS The authors conclude that the use of IV hyoscine butylbromide is recommended for OMP-enhanced abdominal MR imaging with T1-weighted SE pulse sequences at 1.5 T.
