Even young patients with no alarm symptoms should undergo endoscopy for earlier diagnosis of gastric cancer

BACKGROUND AND STUDY AIMS: There has been a tendency in recent years to omit endoscopy in dyspeptic patients younger than 45 years with no so-called "alarm symptoms." This study was conducted to test whether this policy might lead to an increased rate of delayed diagnosis of gastric cancer, especially in a population with a high prevalence of the disease. PATIENTS AND METHODS: The study included 860 patients (465 women, 395 men; median age 44) referred for the first time for upper gastrointestinal endoscopy because of suspected upper gastrointestinal pathology, to a secondary referral center between 1983 and 1993. Symptoms were assessed using a special questionnaire prior to endoscopy. The endoscopic diagnosis was always confirmed by histology. RESULTS: Gastric cancer was found in 83 patients (12 early cancers, 71 advanced). Patients with cancer were predominantly male (68 %, compared with 44 % in the no-cancer group; P < 0.001), and significantly older (median age 56, 44 and 42 years for advanced, early cancer, and no cancer, respectively; P < 0.001). As many as 24 % of patients with cancer were aged under 45 years. Symptoms occurring more frequently in the gastric cancer group compared with the no-cancer group were weight loss (11 % vs. 0.1 %; P < 0.001), gastrointestinal bleeding (18 % vs. 8 %; P < 0.001), anorexia (43 % vs. 25 %; P < 0.001), and fatigue (53 % vs. 30 %; P < 0.001). In 27 % of cancer patients none of the above symptoms was observed. No statistical difference was seen for pain, nausea, vomiting, and other symptoms. The mean symptom score (1 point for one symptom) was higher in patients with cancer compared with those without (3.1 vs. 2.4; P < 0.001). The duration score (1 to 4 points for durations of less than 6, less than 12, less than 24, and more than 24 months) was lower (1.3 vs. 1.8; P < 0.001) in cancer patients. In three-quarters of cancer patients the duration of symptoms was shorter than 6 months. CONCLUSIONS: Symptoms suggesting gastric cancer are gastrointestinal bleeding, weight loss, and to a lesser degree anorexia and fatigue. Gastric cancer patients show a greater intensity but shorter duration of symptoms than patients with no cancer. Age and alarm symptoms cannot determine the need for upper gastrointestinal endoscopy, at least in areas of high prevalence of gastric cancer.     

The prevalence and significance of increased gastric wall radiotracer uptake in sestamibi myocardial perfusion SPECT

Background: Limited available data indicate that a specific pattern of increased gastric wall radiotracer uptake is associated with dyspepsia. Our purpose was to evaluate the frequency of this finding and its relation with dyspeptic evidences. Method: 1056 consecutive outpatients referred for myocardial perfusion SPECT were interviewed concerning the dyspeptic symptoms, current gastric medications and previous gastroduodenal interventions. The intensity of gastric wall activity was graded qualitatively as G1 or hyperactive gastric wall (equivalent to the patient’s heart activity) and G2 (less than heart activity). Results: The pattern of gastric wall hyperactivity was identified in 1.9% of patients. Dyspeptic symptoms were present in 80 and 18.6% of G1 and G2 patients, respectively (p<0.001). The dyspeptic symptoms were classified as ulcer-like in 37.5%, dysmotility-like in 43.75% and GERD-like in 18.75% of the dyspeptic G1 patients. Considering the classification of dyspepsia, there was no significant difference between the dyspeptic patients of groups. The history of previous gastroduodenal interventions and current use of gastric medications was significantly higher among G1 patients. Conclusion: The infrequent pattern of gastric wall hyperactivity could be clinically important and can identify a category of patients, who require additional diagnostic gastrointestinal investigation to specify another possible noncardiac origin of complaints.     

Prevalence of unexplained upper abdominal symptoms in patients with migraine

Patients with functional gastrointestinal disorders frequently report migraine. We aimed to determine the prevalence of idiopathic upper abdominal symptoms in patients with migraine and compare it with a control population of healthy blood donors. We assessed abdominal symptoms using the Bowel Disease Questionnaire in a series of 488 consecutive blood donors without migraine and 99 patients with migraine. Upper abdominal symptoms were reported by 38%[95% confidence interval (CI) 32, 44] of blood donors compared with 81% (67, 91, P<0.001) of migraine patients. Of the blood donors, 23% (18, 28) reported frequent dyspepsia compared with 60% (44, 74, P<0.001) of the migraine patients. Migraine was associated with frequent upper abdominal symptoms (odds ratio 2.7, 95% CI 1.2, 6.1) after adjusting for age, gender, smoking and consumption of analgesics and alcohol. Upper abdominal symptoms are significantly more frequent in patients with migraine compared with healthy controls. The association between migraine and idiopathic upper abdominal symptoms may suggest common pathophysiological mechanisms.     

Patients with headache and functional dyspepsia present meal–induced hypersensitivity of the stomach

Headache is a frequent feature of functional gastrointestinal disorders but there is no data on the responsible pathophysiological mechanism. The aim of this study was to verify whether alteration of post–prandial gastric tone or sensitivity might explain this association. Fourteen patients affected by functional dyspepsia (7 migraine without aura) and 7 healthy volunteers (HV) underwent gastric tone measurement in fasting condition and after the administration of a liquid meal by barostat. Gastric volume (GV) and accommodation were calculated as difference between mean post–prandial and mean fasting volume. Mean postprandial GV increase and fasting perception and discomfort threshold (DTh) were similar among the 3 groups. DTh after meal was lower in dyspeptic headache patients than in HV and dyspeptic without headache patients. Patients with migraine and functional dyspepsia may be characterised by meal-induced hypersensitivity of the stomach.     

Migraine Symptoms: Results of a Survey of Self-Reported Migraineurs

Migraine is an episodic headache disorder associated with various combinations of neurologic, gastrointestinal, and autonomic symptoms. Gastrointestinal disturbances including nausea, vomiting, abdominal cramps, or diarrhea are almost universal. Sensory hyperexcitability manifested by photophobia, phonophobia, and osmophobia are frequently experienced. Other symptoms include blurry vision, nasal stuffiness, tenesmus, polyuria, pallor, and sweating, Our telephone interview survey of 500 self-reported migraine sufferers was performed in 1994. The most common reported symptoms associated with migraine were pain, nausea, problems with vision, and vomiting. Nausea occurred in more than 90% of all migraineurs; nearly one third of these experienced nausea during every attack. Vomiting occurred in almost 70% of all migraineurs; nearly one third of these vomited in the majority of attacks. In those who experienced nausea, 30.5% indicated that it interfered with their ability to take their oral migraine medication; in those with vomiting, 42.2% indicated that it interfered with their ability to take their oral migraine medication. The most important features of a migraine medication were rapid and effective relief of headache pain, decreasing the likelihood of headache recurrence, and not causing nausea. Many migraine patients suffer needlessly because their nausea and vomiting are both unreported to, and unrecognized by physicians. The presence of these symptoms is crucial to diagnose migraine not accompanied by aura.     

Transdermal sumatriptan for acute treatment of migraineurs with baseline nausea

Objective.— To evaluate the efficacy and safety of transdermal sumatriptan in migraine patients who have baseline nausea. Background.— Migraine‐associated nausea and vomiting can limit the effectiveness of acute treatment with oral agents by causing delays, avoidance, or incomplete absorption of medication due to post‐dose vomiting. Methods.— In a multicenter, randomized, double‐blind, placebo‐controlled study in adult (aged 18‐66 years) migraineurs, 530 patients were randomized to receive transdermal sumatriptan or a placebo patch and remained in the study until they had treated a single moderate to severe migraine attack or had gone 2 months without treatment. At baseline (before applying the study patch), patients recorded headache pain intensity and the presence or absence of migraine‐associated symptoms, including nausea. The use of analgesic or anti‐emetic rescue medications within 2 hours of patch activation was prohibited. Post‐hoc analyses were conducted to assess the proportion of patients with nausea at baseline who experienced headache relief and who were free from nausea, photophobia, and phonophobia at 1 and 2 hours post‐activation. Results.— A total of 454 patients were included in the intent‐to‐treat population for efficacy analyses. Baseline demographic and migraine headache characteristics were generally similar between the treatment groups. In the overall study population, transdermal sumatriptan was significantly superior to placebo at 1 hour post‐activation for pain relief (29% vs 19%, respectively; P < .0135) and freedom from nausea (71% vs 58%, respectively; P < .05) and at 2 hours post‐activation for freedom from pain (18% vs 9%, respectively; P < .009), pain relief (53% vs 29%, respectively; P < .0001), freedom from nausea (84% vs 63% respectively; P < .001), freedom from photophobia (51% vs 36%, respectively; P < .0028), freedom from phonophobia (55% vs 39%, respectively; P < .0002); and freedom from migraine (16% vs 8%, respectively; P < .0135). In the post‐hoc analysis, transdermal sumatriptan was markedly superior to placebo for pain relief and freedom from pain, nausea, photo‐, and phonophobia at 1 and 2 hours post‐activation. Conclusions.— Transdermal sumatriptan is superior to oral triptans for migraine patients whose baseline nausea causes them to delay or avoid acute treatment.     

High-risk ED patients with nonvariceal upper gastrointestinal hemorrhage undergoing emergency or urgent endoscopy: a retrospective analysis

OBJECTIVES: The optimal timing of interventional endoscopy within the initial 24 hours remains controversial. We designed a retrospective study to compare the outcomes between emergency endoscopy (EE) and urgent endoscopy (UE) for high-risk patients with nonvariceal upper gastrointestinal hemorrhage presenting to the emergency department (ED). METHODS: The medical records of 189 patients with nonvariceal upper gastrointestinal hemorrhage who underwent endoscopy within 24 hours of admission to the ED were reviewed. Patients were divided into 2 groups: EE group (<8 hours) or UE group (8-24 hours). We compared the endoscopic findings, hemostatic procedures, rate of hemostasis, rebleeding, need for transfusion, length of hospitalization, and mortality between the 2 groups. RESULTS: There were 88 patients (47%) in the EE group and 101 patients (53%) in the UE group. Ulcers with active bleeding or exposed vessel were found more frequently in the EE group than in the UE group (19% vs 8%, P = .03; 34% vs 12%, P < .001). Fifty patients had blood retention in the stomach, especially in the EE group (40% vs 15%, P < .001). Forty-four (50%) patients in the EE group and 21 (21%) patients in the UE group received endoscopic interventions. Combination modalities of endoscopic hemostasis were more commonly used in the EE group than in the UE group (40% vs 15%, P < .001). Primary hemostasis was achieved at a rate of 95% in both groups. There was no statistical difference regarding the rate of recurrent bleeding, total amount of transfusion, length of hospital stay, and mortality rate in both groups. CONCLUSIONS: Although more active lesions were detected and more therapeutic attempts were performed in the EE group, the outcome showed no difference in both groups. Emergency endoscopy performed less than 8 hours after arrival to the ED showed no definite benefit in comparison with UE performed within 8 to 24 hours.     

An assessment of the potential value of endoscopic ultrasound as a cost-minimizing tool in dyspeptic patients with persistent symptoms

STUDY AIMS: To quantify resource utilization in dyspeptic patients with persistent symptoms and to determine whether using both the endoscopic and ultrasound capabilities of endoscopic ultrasound could reduce costs. METHODS: Consecutive patients with persistent dyspepsia, after a minimum 1-month trial of acid suppression, underwent endoscopic ultrasound (EUS) and upper endoscopy using the GF-UM20 echo endoscope. Assuming EUS could replace imaging tests which had been requested in addition to upper endoscopy, the hypothetical costs of the EUS-based and upper endoscopy-based strategies were compared. RESULTS: 116 patients with persistent dyspepsia underwent EUS, of whom 64.6 % had > or = 2 imaging procedures, most commonly computed tomography (CT) (70.6 %) and abdominal ultrasound (64.7 %). The number of tests did not correlate strongly with any demographic variables. The fiberoptic echo endoscope provided an adequate endoscopic and ultrasound examination but was damaged by retroflexion. Direct hospital costs were lowest for the EUS-based strategy. Total avoidable cost for 116 patients was $ 4137 to $ 14 121 (or $ 36 to $ 122 per patient), depending on whether upper endoscopy was performed in the non-EUS strategies. CONCLUSIONS: Patients with persistent dyspepsia may undergo multiple abdominal imaging procedures. Clinical variables do not predict the need for additional testing. An EUS-based strategy may reduce overall costs if it prevents additional testing.     

A trial of a test-and-treat strategy for Helicobacter pylori positive dyspeptic patients in general practice

Computer models of different strategies for the management of dyspepsia in primary care indicate that a 'test-and-treat' approach is likely to be associated with the lowest costs and acceptable clinical outcomes. We present information on computer modelling studies and report the findings of a randomised trial comparing a Helicobacter pylori test-and-treat strategy with referral to direct access endoscopy in the management of dyspepsia in general practice. We compared costs and clinical outcomes in patients managed for one year in study (test-and-treat) and control (endoscopy) practices in south London. Patients aged less than 45 years presenting with persistent dyspepsia without alarm symptoms (141 study patients, 91 control patients) were studied. In the one-year follow-up period there were 17 endoscopies in the study group: all the control patients underwent initial endoscopy and five further endoscopies were performed. None revealed peptic ulcer or cancer. Forty-three (30%) of the study patients compared with 16 (17%) of the controls were referred to hospital clinics (p < 0.025). The cost of management per patient for one year in the study group was 205.67 Pounds, compared with 404.31 Pounds in the control group (p < 0.0001). Clinical outcomes in both groups at one year were comparable. An H. pylori test-and-treat strategy for dyspeptic patients aged less than 45, employing office-based serology testing, appears to be associated with substantially lower costs than initial endoscopy and with similar clinical outcomes.

Gastroduodenal morphology and related symptoms in chronic alcoholics

Twenty-four chronic alcoholics admitted to hospital for detoxification after a drinking spree were examined by upper gastrointestinal endoscopy. Biopsy specimens were taken from corpus/fundus, antrum and duodenum for tissue histology (eosin stain). From the duodenum villus index and ultrastructure (scanning electron microscopy, SEM) were also performed. As a control group 12 subjectively healthy non-alcoholics referred to upper gastrointestinal endoscopy mainly for dyspepsia were chosen.Gastrointestinal symptoms were common in alcoholics (88%). Endoscopic and histological gastroduodenitis were not more common in the alcohol group. There was no correlation between gastrointestinal symptoms and endoscopic or histological gastroduodenitis in both groups. In the duodenum, 50% of the alcoholics and 82% in the control group had alterations by scanning electron microscopy. Ten of the 11 alcoholics with an abnormal ultrastructure had diarrhoea. In the control group dyspepsia (ulcus suspect) was correlated to a pathological SEM.     

Association between Helicobacter pylori cytotoxic type I CagA-positive strains and migraine with aura

Recent studies have suggested an association between Helicobacter pylori infection and migraine. However, various strains of the bacterium are present, some endowed with greater pathogenicity. In particular, H. pylori type I CagA-positive strains induce a higher release of proinflammatory substances by the gastric mucosa that could trigger systemic vasospasms. The aim of the present study was to assess the prevalence of H. pylori CagA-positive strains in subjects with migraine. One hundred and seventy-five patients affected by migraine (49 with aura, 126 without aura) were consecutively enrolled and matched for sex, age, social background and geographical origin with 152 controls. Helicobacter pylori infection was assessed through 13C-urea breath test. Specific serological IgG against CagA were detected through ELISA. The prevalence of H. pylori infection was similar in migraine patients and in controls (40% vs. 39%, respectively). Among migraine patients, prevalence of infection was not related to presence or absence of aura (45% vs. 37%, respectively). However, among infected subjects, a significantly higher prevalence of CagA-positive strains was observed in patients affected by migraine with aura when compared with those affected by migraine without aura (41% vs. 19%, P < 0.01) and with controls (41% vs. 17%, P < 0.01). CagA-positive H. pylori strains were found to be strongly associated with migraine with aura. A higher inflammatory response of the gastric mucosa to more virulent strains could release substances that may act as triggers of vasospasm in peculiar cerebral arterial districts, probably implicated in the 'aura' phenomenon.     

Dyspepsia in AIDS is correlated to ultrasonographic changes of antral distension.

OBJECTIVES: Patients with acquired immune deficiency syndrome (AIDS) frequently complain about dyspeptic symptoms. We set out to test whether changes in antral emptying or antral distension may account for these dyspeptic symptoms in AIDS. METHODS: We studied antral emptying in ten patients with HIV infection (CDC 1993 classification stage C) by means of an established real-time ultrasonographic method. Organic abdominal lesions had been excluded. Six upper gastrointestinal symptoms were evaluated using a score ranging from 0 to 3. Fifteen subjects without any abdominal complaints and without any abdominal history served as controls. Antral cross sectional area was measured after an overnight fast and at 0, 15, 30, 45, 60, 90, 120 min after an semisolid test meal. Antral postprandial distension was expressed using an antral expansion ratio (postcibal antral area/fasting antral area). Gastric emptying of the test meal was derived from the measurement of the area under the postcibal antral distension curve (AUC). RESULTS: Fasting antral cross sectional area and AUC (gastric emptying) were similar in both groups. Antral postprandial expansion tended to be lower in AIDS patients compared to controls (mean+/-S.D.): 288+/-84 versus 397+/-156%; P=0.08. In AIDS patients the symptom score of dyspepsia showed a positive correlation (r=0.55; P<0.05) with fasting antral area and a negative correlation (r=-0.62; P<0.05) with postprandial expansion. No signs of autonomic neuropathy were to be found in the AIDS patients tested in this study. CONCLUSION: A wider fasting antral cross sectional area and an impaired antral postprandial expansion are related to dyspeptic symptoms in AIDS patients. This suggests the same relationship between dyspeptic symptoms and disturbed antral distension as seen in other patients with functional dyspepsia.     

<Emphasis Type="Italic">Helicobacter pylori</Emphasis> infection as an environmental risk factor for migraine without aura

Helicobacter pylori (H. pylori) infection has recently been associated with various extraintestinal pathologies and migraine. The aim of this study was to investigate the correlation of the H. pylori infection with the pathogenesis of migraine without aura, especially in cases not affected by endogenous risk factors, like hereditary pattern or hormonal fluctuations. A total of 49 outpatients (37 females and 12 males; age range: 19–47 years; mean age: 31,±14 years) affected by migraine without aura was evaluated. We divided them in 2 subgroups: a) with positive familial history, and/or with menstrual type of migraine b) with negative familial history and with menstrual unrelated type of migraine. H. pylori infection was diagnosed by the 13 C- urea breath test (INFAI — test). Control subjects consisted of 51 patients without any primary headache history (38 females; mean age of 32,±14,4 years; range 21–49 years), who underwent upper gastrointestinal (GI) endoscopy for investigation of anaemia or non ulcer dyspepsia. H. pylori detection was based on the histologic analysis of gastric mucosa biopsy. The prevalence of H. pylori infection was significantly higher in the migraineurs without aura compared to controls (p=0.016). The prevalence of H. pylori infection was significantly high in the mixed and in the female group of our patients without other predisposing factors for migraine without aura (81 and 87% respectively), while in the same groups with predisposing factors (menstruation and/or family history) the prevalence was only 36 and 37% respectively (p=0,001 for the first group and p=0,002 for the second group). Our results seem to highlight the role of H. pylori infection as a probable independent environmental risk factor for migraine without aura, especially in patients that are not genetically or hormonally susceptible to migraine.     

Gastric myoelectrical activity and gastrointestinal motility in patients with functional dyspepsia

Abstract. The aim of our study was to examine the prevalence of gastric myoelectrical disturbances in relation to gastrointestinal motility abnormalities in patients with functional dyspepsia, using simultaneous electrogastrography and antroduodenojejunal manometry. We carried out electrogastrography in 20 patients with functional dyspepsia and in 20 healthy volunteers. In 10 of these patients and in 10 of the volunteers antroduodenojejunal manometry was performed simultaneously. Apart from a higher postprandial power content of the 3 cycles per minute (cpm) component in the patients (1263 ± 317 and 393 ± 101 μV², respectively; P = 0.016), no differences in the electrogastrographic variables were found between the groups. In the manometric part of the study, postprandial antral hypoactivity was not a prominent finding. Instead, small intestinal hyper-activity was found in the dyspeptic patients, with both a higher frequency and amplitude of the contractions ( P < 0.05). This hyperactivity often consisted of bursts, which were significantly more frequent in patients than in control subjects (total duration of burst activity 25.6 ± 6.4 and 6.0 ± l.7 min, respectively; P = 0.013). A positive correlation was found between the frequency of the gastric electrical control activity and the antral contraction frequency ( P = 0.006), between the power content of the electrographic signal and the antral contraction amplitude ( P = 0.025), and between the postprandial/fasting electrographic power ratio and the antral motility index ( P = 0.007). In conclusion, gastric myoelectrical activity is minimally disturbed in patients with functional dyspepsia. Motor abnormalities, especially small intestinal hyperactivity, are more likely to play a prominent role in the genesis of dyspeptic symptoms.     

Efficacy of sumatriptan tablets in migraineurs self-described or physician-diagnosed as having sinus headache: a randomized, double-blind, placebo-controlled study

BACKGROUND: Many patients and physicians interpret episodic headache in the presence or absence of nasal symptoms as "sinus' headache, while ignoring the possible diagnosis of migraine. OBJECTIVE: The purpose of this study was to assess the efficacy and tolerability of sumatriptan succinate 50-mg tablets in patients with migraine presenting with "sinus" headache. METHODS: A randomized, double-blind, placebo-controlled, multicenter study was conducted in adult (aged 18-65 years) migraine patients presenting with self-described or physician-diagnosed "sinus" headache. From November 2001 to March 2002, patients meeting International Headache Society criteria for migraine (with > or =2 of the following: unilateral location, pulsating quality, moderate or severe intensity, aggravation by moderate physical activity; and > or =1 of: phonophobia and phonophobia, nausea and/or vomiting) and with no evidence of bacterial rhinosinusitis were enrolled and randomized in a 1:1 ratio via computer-generated randomization schedule to receive either 1 sumatriptan 50-mg tablet or matching placebo tablet. The primary efficacy end point was headache response (moderate or severe headache pain reduced to mild or no headache pain) at 2 hours after administration. The presence or absence of migraine-associated symptoms and sinus and nasal symptoms was also measured. Tolerability was assessed through patient-reported adverse events (AEs). RESULTS: Two hundred sixteen patients with self-described or physician-diagnosed "sinus" headache received a migraine diagnosis and treated 1 migraine attack with sumatriptan 50 mg. The efficacy (intent-to-treat) analysis included 215 patients treated with sumatriptan 50 mg (n = 108; mean [SD] age, 39.6 [12.3] years; mean [SD] weight, 77.7 [17.7] kg; sex, 71% female; race, 69% white) or placebo (n = 107; mean [SD] age, 41.0 [11.3] years; mean [SD] weight 80.7 [20.9] kg; sex, 69% female; race, 64% white). Significantly more patients treated with sumatriptan 50 mg achieved a positive headache response at 2 and 4 hours after administration compared with those treated with placebo (69% vs 43% at 2 hours and 76% vs 49% at 4 hours, respectively; both, P < 0.001). Significantly more sumatriptan-treated patients were free from sinus pain compared with placebo recipients at 2 hours (63% vs 49% placebo, P = 0.049) and 4 hours (77% vs 55%, P = 0.001). All treatments were generally well tolerated. The most common drug-related AEs reported in the sumatriptan and placebo groups, respectively, were dizziness (5% vs < 1%), nausea (3% vs 2%), other pressure/tightness (defined as sense of heaviness; heaviness of upper body, upper extremities; jaw tension; neck tension) (4% vs 0%), and temperature sensations (defined as warm feeling of back of neck, or flushing) (2% vs 0%). No patients experienced any serious AEs. CONCLUSIONS: Sumatriptan 50-mg tablets were effective and generally well tolerated in the treatment of these patients presenting with migraine headaches that were self-described or physician-diagnosed as sinus headaches.     

Long-term safety and clinical effectiveness of controlled-release metoclopramide in cancer-associated dyspepsia syndrome: a multicentre evaluation

Patients with cancer frequently report gastrointestinal symptoms such as anorexia, early satiety, nausea, vomiting, and bloating. A reduction of the severity of some of these symptoms would benefit the patient by enhancing quality of life and improving their treatment. Forty-eight patients (25 female and 23 male; mean age 63 +/- 11 years) with a minimum two-week history of cancer-associated gastrointestinal symptoms were assigned to a single, open-label treatment group and received controlled-release metoclopramide 20 mg-80 mg q12h for a maximum period of 12 weeks (mean 46 +/- 35 days). There was a 40%-60% decrease in the severity of nausea over the first two weeks of treatment, and an approximate 50% reduction in severity of vomiting over the first four weeks of treatment. Appetite and bloating also improved, although smaller and less consistent changes were observed. Patient ratings of overall clinical effectiveness with respect to relief from symptoms and tolerability of side effects indicated that controlled-release metoclopramide was highly and moderately effective in 36% and 30% of the patients, respectively. Controlled-release metoclopramide is a useful treatment for the management of gastrointestinal symptoms associated with the cancer-associated dyspepsia syndrome including nausea, vomiting, loss of appetite, and bloating.     

Predictors of delayed gastric emptying in diabetes.

OBJECTIVE: To define the predictors of the rate of gastric emptying in patients with diabetes. RESEARCH DESIGN AND METHODS: A total of 101 outpatients with diabetes (79 type 1 and 22 type 2) underwent measurements of gastric emptying of a solid/liquid meal (scintigraphy), upper gastrointestinal symptoms (questionnaire), glycemic control (blood glucose concentrations during gastric emptying measurement), and autonomic nerve function (cardiovascular reflexes). RESULTS: The gastric emptying of solid and/or liquid was delayed in 66 (65%) patients. Solid (retention at 100 min 64 +/- 3.2 vs. 50.2 +/- 3.6%, P < 0.005) and liquid (retention at 100 min 22.7 +/- 1.7 vs. 16.0 +/- 1.8%, P < 0.001) gastric emptying was slower in women than in men. Of all upper gastrointestinal symptoms (including nausea and vomiting), only abdominal bloating/fullness was associated with slower gastric emptying (P < 0.005). A multiple regression analysis demonstrated that both abdominal bloating/fullness and female sex were predictors of slower gastric emptying of both solids and liquids. CONCLUSIONS: We conclude that the presence of abdominal bloating/fullness but not any other upper gastrointestinal symptom is associated with diabetic gastroparesis and that gastric emptying is slower in diabetic women than in diabetic men.     

Partial seizure: an unusual cause of recurrent vomiting

Partial seizure is a rare cause of nausea and vomiting. We report an adult patient with abdominal discomfort lasting 15 years accompanied by nausea and vomiting at least twice a week. On admission, physical examination and detailed laboratory tests were normal. Abdominal ultrasound examination, upper gastrointestinal endoscopy and CT scanning of the brain did not reveal any evidence of disease. Electroencephalography revealed bilateral synchronous sharp wave discharges and spike wave activities. The diagnosis of partial seizure was considered and the patient was administered sodium valproate. The patient's symptoms subsided and he has been asymptomatic for the past 20 months. We conclude that partial seizure should be considered in patients suffering from abdominal complaints who do not have any underlying gastrointestinal disorder.
