The need for a rotavirus vaccine in any particular country depends primarily on the number of hospitalized cases. Since only limited data are available for Germany, we undertook a retrospective hospital-based analysis in order to gather further information. From 1987 through 1996, a total of 3618 inpatients were hospitalized with a diagnosis of gastroenteritis (ICD 9). In 892 (25%) of them the causative organism wasa rotavirus. During the same period, 1886 (out of 8383; 22%) stool speciment tested in the hospital laboratory were obtained from rotavirus-positive inpatients. In 49.2% the infection was community-acquired, and in the remainder of nosocomial origin. Infants under 4 months of age(n=709; 38%) predominated among both the nosocomial and community-acquired infections. Premature neonates made up 26% of the nosocomial, but only 2% of the community-acquired cases of diarrhoea. The winter peak (January) was most pronounced in the age group 4-12 months, but in those more than 1 y old the peak came a month later. The median hospitalization time for community-acquired cases was 4 d (mean 5.9 d).The mortality was 0.1%. Rotavirus infection must therefore be regarded as a considerable burden, particularly with regard to infants and young children. Furthermore, the morbidity due to nosocomial infection with the rotavirus, analysed here in a long-term observational study, is unexpectedly high. □ Hospital-based study, nosocomial infection, rotavirus  相似文献

Treatment of gastroparesis: a multidisciplinary clinical review   总被引:9,自引:0,他引:9  
This clinical review on the treatment of patients with gastroparesis is a consensus document developed by the American Motility Society Task Force on Gastroparesis. It is a multidisciplinary effort with input from gastroenterologists and other specialists who are involved in the care of patients with gastroparesis. To provide practical guidelines for treatment, this document covers results of published research studies in the literature and areas developed by consensus agreement where clinical research trials remain lacking in the field of gastroparesis.  相似文献

Abstract  To investigate whether there is an association between gastric emptying rate and symptom improvement in gastroparetic patients treated with gastric electrical stimulation (GES), we retrospectively reviewed 63 gastroparetic patients who received GES therapy for at least 1 year. Patient characteristics, seven upper gastrointestinal (GI) symptoms and 4-h standardized gastric emptying test (GET) were evaluated at baseline and at 1 year of GES. All symptoms were significantly reduced ( P  <   0.001). Mean gastric retention was reduced by 7% ( P  =   0.102) for measurement at 4 h. Of the 63 patients, 14 had their GET normalized and 49 remained delayed after 1 year. Normalized GET patients had a similar symptom improvement as those whose GET remained delayed. Of all upper GI symptoms, the improvements in vomiting ( P  =   0.04), nausea ( P  =   0.002) and epigastric pain ( P  =   0.001) were significantly correlated with reduction in 4-h gastric retention between baseline and 12 months of GES therapy for patients with normalized gastric emptying but there were no correlations with any symptoms and change in gastric emptying for those patients who remained delayed. In summary, overall gastric emptying is not significantly accelerated at 4 h after successful symptomatic improvement with GES but nausea, vomiting and epigastric pain can be correlated with normalization of GET in a subset of patients.  相似文献

The aims were to determine symptom responses and long-term outcomes in gastroparetic patients receiving gastric electrical stimulation (GES) therapy beyond 3 years by presenting per protocol analysis and intention-to-treat (ITT) analysis. Data collected at baseline, 1 year and beyond 3 years in 55 patients included total symptom scores (TSS), nutritional status, weight, hospitalizations, the use of prokinetic and/or antiemetic medications, HbA1c in diabetics and adverse events. Of the 55 patients, 10 died of non-pacemaker-related complications, six had the devices removed and two could not be reached. The remaining 37 patients had the device activated for a mean of 45 months. Both per protocol and ITT analysis demonstrated that TSS, hospitalization days and the use of medications were all significantly reduced at 1 year and were sustained beyond 3 years. Average TSS decreased by 62.5% for the 37 patients completing 3 years of GES. At implantation, 15/37 patients required nutritional support and only five continued beyond 3 years. Mean HbA1c level in diabetics was significantly reduced from 9.5 to 7.9% at 3 years. We conclude that a significant improvement in symptoms and all measures of clinical outcome can be maintained for greater than 3 years with GES in patients with refractory gastroparesis.  相似文献

Abstract  Our goal was to investigate associations between the status of interstitial cells of Cajal (ICC) and electrogastrogram (EGG) parameters, gastric emptying and symptoms in a large cohort of patients with gastroparesis. Forty-one patients with refractory gastroparesis who were referred for gastric electrical stimulation (GES) underwent full thickness gastric (antrum) biopsy during the surgery to place the GES device. The biopsy samples were stained with c-kit and scored for the presence of ICC based on criteria obtained from 10 controls. All patients underwent EGG recordings, a 4-h standardized scintigraphic gastric emptying study and symptom assessment prior to the surgery. Based on antral biopsy, 15 patients (36%) had almost no ICC (ICC− group) and 26 patients had adequate cell numbers (ICC+ group). EGG recordings in the ICC− group displayed significantly less normal slow waves than in the ICC+ group both in the fasting and fed states. Tachygastria in the ICC− group was significantly more than in the ICC+ group both in the fasting (32 ± 8% vs 11 ± 2%) and fed states (27 ± 9% vs 12 ± 2%). There was no statistical difference in gastric emptying, symptom severity of gastroparesis, aetiology, age and gender between the two groups. Severely depleted ICC occurs in up to 36% of gastroparetic patients and significantly correlates with an abnormal EGG. Severely depleted ICC does not correlate with the severity of gastroparesis as assessed by gastric emptying or symptom status but did result in a poorer symptomatic response to GES. These data suggest that the EGG may have a role for predicting ICC status during clinical evaluation of gastroparetic patients.  相似文献
