Intermittent hyperammonemic encephalopathy after ureterosigmoidostomy: spontaneous onset in the absence of hepatic failure

2015

Intermittent hyperammonemic encephalopathy after ureterosigmoidostomy is a rare, but if unrecognized, potentially lethal condition. Ureterosigmoidostomy was performed in a male patient with bladder extrophy. After 35 years, he developed hyperammonemic encephalopathy. Diagnostic procedures did not reveal hepatic nor metabolic disorders. Despite administration of preventive medical treatment, several episodes recurred. A durable prevention was finally achieved by conversion into an ileal conduit. Intermittent hyperammonemic encephalopathy can occur decades after ureterosigmoidostomy. In the case of absence of metabolic disorders and resistance to medical treatment, conversion into a urinary d…

Extracorporeal shock wave lithotripsy of urinary calculi: experience in treatment of 3,278 patients using the Siemens Lithostar and Lithostar Plus.

1991

Between March 1986 and June 1989, 3,278 patients with upper urinary tract calculi were treated at our medical center with the Lithostar lithotriptor. The stones were located in the calices in 41.9% of the cases, renal pelvis in 25.7% and ureter in 32.4%. Perirenal hematoma was noted in 0.5% of the patients but this resolved spontaneously within a few days. Auxiliary procedures were performed in 37.3% of the cases, including Double-J stent and ureteral catheter in 26.8%, ureterorenoscopy in 2.1%, percutaneous nephrostomy in 1.6%, Zeiss loop in 4.3% and percutaneous nephrolithotripsy in 3.5%. Of the treatments 83.1% were performed without general or regional anesthesia. Followup after 3 month…

The effect of gestational age and cervical length measurements in the prediction of spontaneous preterm birth in twin pregnancies : an individual pat…

2016

OBJECTIVE: To assess the effect of gestational age (GA) and cervical length (CL) measurements at transvaginal ultrasound (TVUS) in the prediction of preterm birth in twin pregnancy. DESIGN: Individual patient data (IPD) meta-analysis. SETTING: International multicentre study. POPULATION: Asymptomatic twin pregnancy. METHODS: MEDLINE and EMBASE searches were performed and IPD obtained from authors of relevant studies. Multinomial logistic regression analysis determined probabilities for birth at ≤28(+0) , 28(+1) to 32(+0) , 32(+1) to 36(+0) , and ≥36(+1) weeks as a function of GA at screening and CL measurements. MAIN OUTCOME MEASURES: Predicted probabilities for preterm birth at ≤28(+0) , 2…

Power of lower extremities and age were the main determinants on the agility test for adults in a cohort of men aged 66–91 years

2019

Study Design: Cross-sectional study. Objective: To evaluate the relationship between agility and personal factors, muscle strength and power, mobility, self-reported balance and physical activity among older men. Methods: Agility was measured by using the Agility Test for Adults (ATA). We studied 100 Finnish male former elite athletes (endurance n = 50; power n = 50) and 50 matched controls aged 66 to 91 years (mean age 75.5 years). The associations between agility and other variables were similar between three groups; thus, multiple linear regression analyses were done by using the pooled data of the participants. Results: On the basis of multiple linear regression analyses, combination of…

Continent urinary diversion in childhood

1992

Continence and a positive body image are important, especially to the adolescent patient. Since 1964 we have used ureterosigmoidostomy and have achieved a complete continence rate of 92.3%. The creation of a low-pressure reservoir by antimesenteric splitting of the recto-sigmoid eliminated many of the shortcomings of ureterosigmoidostomy. This procedure is termed the sigma-rectum pouch and has been applied in six children to date. Mainz-pouch bladder augmentation or substitution has been performed in 20 children, 17 of whom are completely continent. The results of the modified Young Dees procedure were disappointing. In three children, conversion into a continent diversion was necessary. Al…

Influence of induced intrauterine diuresis on the upper urinary tract

1993

There are many possible etiologies of sonographically detected dilatation of the renal pelvis and the ureter during pregnancy. The observation that fetal ureteral dilatation occurs with congenital diabetes insipidus has led to the suspicion of at least a modifying influence resulting from intrauterine diuresis. To increase fetal diuresis experimentally, Wistar rats were treated with 100 mg chlorthalidon and 40 mg furosemide per kg bodyweight per day. The animal experiment was performed with four groups. Group I was treated during the entire course of pregnancy. Group II during the first half and Group III during the second half. Group C was the untreated control group. For morphometric inve…

Kontinente Harnableitung und Schwangerschaft

1995

We report on our experience with 7 pregnancies in 6 women who previously underwent reconstruction of the urinary tract with a continent urinary diversion using an ileo caecal segment (Mainz-Pouch I), ureterosigmoidostomy or bladder augmentation. Urinary tract infection and upper tract dilatation were the only complications during pregnancy which required bilateral nephrostomies in one case. All other sequelae were handled conservatively. The continence mechanisms were not compromised during pregnancy or delivery. Deliveries were vaginal in two cases and by Caesarean section in five. All seven newborn were healthy. Pregnancy is not contraindicated after any type of urinary diversion includin…

Remember, know, confidence and the mirror effect: Changes as a function of discriminability conditions

2003

Recognition memory for Spanish-Catalan cognate and noncognate words was tested at retention intervals of 20 minutes, 1 hour, and 24 hours (Experiment 1) using a remember/know response procedure, and requiring a confidence judgement on the yes/no response. Noncognate words were accompanied by more “remember” responses than cognates, and overall A' was significantly different from remember A', except in the cognate condition at the longest retention interval. A strong mirror effect for the cognate-noncognate stimulus class was found for overall responding, and for high but not low confidence, indicating a differential use of recollection and familiarity in recognition. In general, the pattern…

Peripheral Intravenous Access in Preterm Neonates during Postnatal Stabilization: Feasibility and Safety

2017

Background Current European Guideline for resuscitation recommends a centrally positioned umbilical venous catheter as the best option for administering necessary drugs. Especially in preterm infants, a frequently used alternative is the peripheral venous catheter. Methods Two randomized controlled studies were conducted at the Division of Neonatology, Medical University of Graz. During neonatal resuscitation, a standardized protocol was filled out by an uninvolved observer including time points after birth of all attempts of venous puncture, time point of successful venous puncture, and total number of needed attempts. Arterial oxygen saturation (SpO2) and heart rate (HR) were measured usi…
