OBJECTIVE: To evaluate the outcome of antroduodenal manometry studies and their effect on the clinical treatment of patients. DESIGN: A retrospective review of clinical antroduodenal manometric studies performed between September 1990 and March 1997 (n = 109). SETTING: Tertiary referral centre. MAIN OUTCOME MEASURES: The predominant symptom, the indication for the study, the outcome and the clinical impact were scored. A positive impact was defined as an outcome that resulted in an alteration of the management of the patient (medication, surgery, feeding), established a new diagnosis, or resulted in new investigations or in referral to another specialist. RESULTS: Full records were obtained from 91 studies in 85 patients (mean age 43 years). Nausea and vomiting were the most predominant symptoms (37.4%). In 49.5% of the cases, the test was performed due to suspicion of a generalized motor disorder. A normal outcome was found in 37 studies. Non-specific motor abnormalities were reported in 72% of the studies with an abnormal outcome. Pseudo-obstruction was diagnosed in 20%. The manometric studies resulted in a new therapy in 12.6%, a new diagnosis in 14.9%, and referral to another specialist in 8%. A positive clinical impact was found in 28.7% of the patients. CONCLUSION: Antroduodenal manometry can be a helpful diagnostic technique in a specialized centre. More research is needed to gain insight into the significance of the large number of non-specific abnormalities that are often found. 相似文献

Cholecystokinin (CCK) is the major hormonal stimulus of gallbladder contraction. Both somatostatin and CCK-A receptor antagonists inhibit stimulation of the gallbladder by CCK. The aim of this study was to compare the effect of somatostatin and the CCK-A receptor antagonist loxiglumide (CR 1505) on gallbladder volume at baseline and after feeding.In random order nine healthy subjects received somatostatin (IV loading dose 125 g, followed by IV infusion of 125 g · h–1), loxiglumide (10 mg · kg–1 · h–1) and control saline. Gallbladder volumes and plasma CCK levels were measured basally and during stimulation by an intraduodenal infusion of fat using, respectively, ultrasound and a sensitive and specific radioimmunoassay.Mean basal gallbladder volume was similar prior to the saline control (28.5 ml), loxiglumide (28.7 ml) and somatostatin (23.4 ml) experiments. In the control experiment, intraduodenal fat led to a significant increase in plasma CCK from 2.6 to 4.8 pmol · l–1, accompanied by contraction of the gallbladder to 2.0 ml. Loxiglumide induced dilatation of the gallbladder to 40 ml and prevented the any contraction in response to intraduodenal fat. During the somatostatin infusion, gallbladder volume remained the same both basally and during fat stimulation. The plasma CCK response to intraduodenal fat was exaggerated by loxiglumide and was abolished by somatostatin.We conclude that there are major differences between the effects of loxiglumide and somatostatin on gallbladder motility. Loxiglumide dilates the gallbladder, while somatostatin prevents its contraction during fat stimulation. 相似文献

A divergent rhabdovirus was discovered in the bloodstream of a 15-year-old girl with Nodding syndrome from Mundri West County in South Sudan. Nodding syndrome is a progressive degenerative neuropathy of unknown cause affecting thousands of individuals in Sub-Saharan Africa. The index case was previously healthy until she developed head-nodding seizures four months prior to presentation. Virus discovery by VIDISCA-NGS on the patient’s plasma detected multiple sequence reads belonging to a divergent rhabdovirus. The viral load was 3.85 × 103 copies/mL in the patient’s plasma and undetectable in her cerebrospinal fluid. Further genome walking allowed for the characterization of full coding sequences of all the viral proteins (N, P, M, U1, U2, G, U3, and L). We tentatively named the virus “Mundri virus” (MUNV) and classified it as a novel virus species based on the high divergence from other known viruses (all proteins had less than 43% amino acid identity). Phylogenetic analysis revealed that MUNV forms a monophyletic clade with several human-infecting tibroviruses prevalent in Central Africa. A bioinformatic machine-learning algorithm predicted MUNV to be an arbovirus (bagged prediction strength (BPS) of 0.9) transmitted by midges (BPS 0.4) with an artiodactyl host reservoir (BPS 0.9). An association between MUNV infection and Nodding syndrome was evaluated in a case–control study of 72 patients with Nodding syndrome (including the index case) matched to 65 healthy households and 48 community controls. No subject, besides the index case, was positive for MUNV RNA in their plasma. A serological assay detecting MUNV anti-nucleocapsid found, respectively, in 28%, 22%, and 16% of cases, household controls and community controls to be seropositive with no significant differences between cases and either control group. This suggests that MUNV commonly infects children in South Sudan yet may not be causally associated with Nodding syndrome. 相似文献

Effect of Erythromycin on Gallbladder Emptying in Patients with Antrectomy or Truncal Vagotomy 总被引:2,自引:0,他引:2

Objectives : Erythromycin, a motilin-like agent, stimulates gallbladder contraction in healthy control subjects. Because the action of erythromycin is cholinergic dependent and possibly related to premature phase III migrating motor complex activity in the antrum, we investigated the effect of erythromycin on gallbladder volume in six patients with truncal vagotomy without gastric resection and 14 patients with antrectomy (6 with Billroth 1 anastomosis, 8 with Billroth II anastomosis), and we compared the results obtained with those in eight healthy controls. In addition, the effect of meal ingestion on gallbladder volume was studied. Methods : Gallbladder volumes, measured with ultrasonography, were determined every 15 min for 180 min after erythromycin infusion (3 ing/kg i.v. ), as well as 30 and 60 min after meal ingestion. Results : Basal gallbladder volumes were not significantly different among the four groups. Erythromycin induced a significant ( p < 0.01–0.05) gallbladder contraction of maximal 46 ± 6% in the controls, 49 ± 9%c in the patients with truncal vagotomy, and 38 ± 7% in the patients with antrectomy and Billroth I anastomosis. In the patients with antrectomy and Billroth II anastomosis, no significant reduction in gallbladder volume after erythromycin was observed. Meal-induced gallbladder contraction was normal in all patients, including those with Billroth II anastomosis. Conclusions : These results indicate that neither the long vagus nerve nor the antrum is essential for erythromycin-induced effects on the gallbladder. Because no significant reduction in gallbladder volume in response to erythromycin was observed in the patients with antrectomy and Billroth II anastomosis, we suggest that duodenojejunal anatomical integrity is essential for crythromycin-in-duced gallbladder contraction. 相似文献
