Aim The aim of this study was to describe neuroimaging patterns associated with arterial ischaemic stroke (AIS) in childhood and to differentiate them according to stroke aetiology. Method Clinical and neuroimaging (acute and follow‐up) findings were analysed prospectively in 79 children (48 males, 31 females) aged 2 months to 15 years 8 months (median 5y 3mo) at the time of stroke by the Swiss Neuropaediatric Stroke Registry from 2000 to 2006. Results Stroke was confirmed in the acute period in 36 out of 41 children who underwent computed tomography, in 53 of 57 who underwent T2‐weighted magnetic resonance imaging (MRI) and in all 48 children who underwent diffusion‐weighted MRI. AIS occurred in the anterior cerebral artery (ACA) in 63 participants and in all cases was associated with lesions of the middle cerebral artery (MCA). The lesion was cortical–subcortical in 30 out of 63 children, cortical in 25 out of 63, and subcortical in 8 of 63 children. Among participants with AIS in the posterior circulation territory, the stroke was cortical–subcortical in 8 out of 16, cortical in 5 of 16, and thalamic in 3 out of 16 children. Interpretation AIS mainly involves the anterior circulation territory, with both the ACA and the MCA being affected. The classification of Ganesan is an appropriate population‐based classification for our Swiss cohort, but the neuroimaging pattern alone is insufficient to determine the aetiology of stroke in a paediatric population. The results show a poor correlation between lesion pattern and aetiology. 相似文献

It has been previously reported that intravenous application of cisapride leads to a contraction of the gallbladder. To evaluate this potential prokinetic effect cisapride was given to healthy subjects in the clinically relevant oral form. In a randomized double-blinded placebo controlled design gallbladder volumes were monitored by ultrasound. Orally given single doses above 5 mg cisapride resulted in a significant increase of gallbladder volume reaching a maximum of 176.7 ± 10.0% at 90 min after ingestion of the 40 mg dose. This effect was observed over more than 3 h. Contraction after a standard meal was significantly impaired by 20 mg cisapride (minimal residual volumes 8.4 ± 2.3% vs. 18.7 ± 3.7%; P < 0.05). Refilling of the gallbladder started significantly earlier after cisapride ingestion. The underlying mechanisms of these observations being in contrast to the prokinetic effects cisapride generally exerts on the gastrointestinal tract are still unknown. 相似文献

At the end of extracorporeal shockwave lithotripsy (ESWL) gallstone fragments are dispersed throughout the gall-bladder. In this state they should be expelled more easily than when later sedimented to the gall-bladder fundus. Thus, a randomized study was performed to evaluate the clinical benefit of induced gall-bladder contraction after ESWL. One hundred and five patients with radiolucent gallstones (1–3 stones, diameter ≤ 30 mm) were randomized to received either saline or an infusion of 0.2 μg/kg ceruletide. Stone clearance rates and incidence of biliary symptoms were recorded. Clearance rates at 6 weeks and 3 months after ESWL were significantly (P≤ 0.025) improved by the ceruletide infusion. This effect, resulting in shortened bile acid therapy, was limited to patients with small solitary stones and dependent on a good initial fragmentation. Major side effects attributable to ceruletide were not observed. These results suggest that induced gall-bladder contraction can be successfully applied as an adjuvant treatment in a subgroup of patients with small solitary gallstones. 相似文献

Aim To describe the characteristics of paediatric cerebral sinus venous thrombosis (CSVT) in Switzerland. Method Data on clinical features, neuroimaging, risk factors, and treatment were collected for all children in Switzerland younger than 16 years of age who had CSVT between January 2000 and December 2008. A follow‐up examination and a cognitive assessment were performed (mean follow‐up period 26mo). Differences between neonates and children (patients older than 28d) were assessed and predictors of outcome were determined. Results Twenty‐one neonates (14 males, seven females; mean age 9d, SD 8d) and 44 children (30 males, 14 females; mean age 8y 7mo, SD 4y 5mo) were reported. The incidence of paediatric CSVT in Switzerland was 0.558 per 100 000 per year. In neonates, the deep venous system was more often involved and parenchymal injuries were more common. The strongest predictor of poor outcome was neonatal age (odds ratio 17.8, 95% confidence interval 0.847–372.353). Most children showed global cognitive abilities within the normal range, but impairments in single cognitive subdomains were frequent. Interpretation Paediatric CSVT is rare. Its outcome is poor in neonates. Most children have good neurological outcomes, but some patients have individual neuropsychological impairments. 相似文献

Cisapride increases gallbladder volume in gallstone patients before and after extracorporeal shock wave lithotripsy 总被引:1,自引:0,他引:1

We have previously shown that oral cisapride causes a dose-related increase of fasting gallbladder volume in healthy subjects. The present study investigates the effect of cisapride on gallbladder motility in 16 patients with gallbladder stones: 8 patients had no biliary symptoms, but the other 8 patients with symptomatic gallstone disease were studied before and 6 weeks after extracorporeal shock wave lithotripsy (ESWL). For each study the patients received a single oral dose of 20 mg cisapride; fasting gallbladder volume was measured by ultrasound before, and for 120 minutes after, drug administration. In the 8 asymptomatic patients a mean maximal increase of the fasting volume to 152.7 ± 7.6% of the initial value was observed at a mean 97.5 ± 8.3 minutes after cisapride ingestion. Similarly, in the 8 patients with biliary pain mean fasting volume after cisapride ingestion increased to 141.3 ± 5.7% before ESWL treatment and to 145.0 ± 5.8% after ESWL and 6 weeks of oral litholytic therapy. There were no significant differences between the results in the symptomatic and asymptomatic patients. Our results indicate that cisapride increases the gallbladder volume in gallstone patients regardless of biliary symptoms. Similar volume changes were observed before therapy and after ESWL with bile acid therapy. The therapeutic efficacy of litholytic agents could be diminished by simultaneous cisapride administration. 相似文献

Aim We report on seizures, paroxysmal events, and electroencephalogram (EEG) findings in four female infants with pyridoxine‐dependent epilepsy (PDE) and in one female with pyridoxine phosphate oxidase deficiency (PNPO). Method Videos and EEGs were analysed and compared with videos of seizures and paroxysmal events archived from 140 neonates. PDE and PNPO were proven by complete control of seizures once pyridoxine or pyridoxal 5′‐phosphate was administered and by recurrence when withdrawn. Mutations in the antiquitin gene were found in three patients and in the PNPO gene in one child. Results Seizures began within 48 hours after birth in four newborns and at age 3 weeks in one. Frequent multifocal and generalized myoclonic jerks, often intermixed with tonic symptoms, abnormal eye movement, grimacing, or irritability, were observed in all infants with PDE and PNPO, but rarely in the other archived videos of neonates. EEGs were inconstant and frequently no discernable ictal changes were recorded during the seizures and the paroxysmal events. In addition, interictal EEGs were inconclusive, with normal and abnormal recordings. In older children tonic–clonic seizures, abnormal behaviour, inconsolable crying, frightened facial expression, sleep disturbance, loss of consciousness, paraesthesia, or intermittent visual symptoms were described during controlled and uncontrolled withdrawal or insufficient dosage. Interpretation PDE or PNPO should be considered in infants with prolonged episodes of mixed multifocal myoclonic tonic symptoms, notably when associated with grimacing and abnormal eye movements. 相似文献
