Placental metal concentrations and birth outcomes: The Environment and Childhood (INMA) project
2019
To examine the association of placental levels of arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), manganese (Mn), and chromium (Cr) with birth outcomes (birth weight, length, and head circumference, low birth weight [LBW], gestational age, preterm delivery, and small for gestational age [SGA]) in mother-child pairs from the Environment and Childhood (INMA) Project in Spain.Metal concentrations were measured in placenta tissue samples randomly selected from five INMA cohorts. Data on birth outcomes were obtained from medical records. Associations were assessed in a sub-sample of 327 mother-infant pairs by regression models adjusted for confounding factors and for all metals simultaneous…
Variable phenotypic expression of chylomicron retention disease in a kindred carrying a mutation of the Sara2 gene
2010
Chylomicron retention disease is a recessive inherited disorder characterized by fat malabsorption and steatorrhea and is associated with failure to thrive in infancy. We describe a kindred carrying a mutation of Sara2 gene causing a chylomicron retention phenotype. The proband was a 5-month-old baby, born of consanguineous, apparently healthy parents from Morocco, with failure to thrive. There was a large quantity of fats in feces and malabsorption of fat-soluble vitamins. Intestinal biopsies showed a diffused enterocyte vacuolization with large cytosolic lipid droplets. Chylomicron retention disease or Anderson disease was hypothesized, and the Sara2 gene was analyzed by direct sequencing…
Local excision of urothelial cancer of the upper urinary tract.
1986
Abstract In 9 of 93 patients (9.7%) with urothelial cancer of the upper tract (7 renal pelvis tumors, 3 ureteral tumors), conservative surgery was employed using a free peritoneal autotransplant for replacement of the renal pelvis in 5 kidneys. Absolute indications for conservative surgery were solitary kidneys/nonfunctioning contralateral kidneys in 4 patients and bilateral tumors in 1 patient. Local recurrences developed 1-3 years after operation in 4 of 6 kidneys (3 patients), 3 of which had grade-2 and grade-3 primary lesions. All patients were treated successfully by repeated local excision. In the presence of a normal contralateral kidney, local tumor excision was done electively in 4…
Urinary diversion in children and young adults using the Mainz Pouch I technique
1997
Objectives To determine the late complications and consequences for renal function, vitamin and acid-base metabolism after application of the Mainz Pouch I (MZP-I) technique in children and young adults. Patients and methods To November 1994, the MZP-I procedure was carried out in 463 patients at our institution, 91 of whom were children and adolescents (≤20 years old) using bladder augmentation in 21 and a continent cutaneous stoma in 70. A minimum follow-up of 1 year was possible in 87 patients or 163 renal units (RUs) with a mean of 5.5 years (range 1–10.5). Results At the last examination, 23 of 55 (42%) pre-operatively dilated RUs had improved, 131 of the 163 RUs (80%) were stable and …
Strategies for reconstruction after unsuccessful or unsatisfactory primary treatment of patients with bladder exstrophy or incontinent epispadias.
1999
Following unsuccessful or unsatisfactory primary treatment in patients with the epispadias/exstrophy complex, the options for a surgical solution to preserve the upper urinary tract, to achieve complete continence, and to reconstruct the external and female internal genitalia are limited. We reviewed the records of the patients treated at our institution to determine a surgical compromise between ingenious operative constructions and patient desires, both of which are secondary to stabilization of renal function.From 1967 to December 1997, 128 patients with bladder exstrophy/epispadias complex were treated, of 80 whom had received previous unsuccessful or unsatisfactory treatment. Of these …
Studies on adaptation to complete dentures. Part II: Oral stereognosis and tactile sensibility
1995
High oral perception is thought to contribute to poor adaptation to new dentures. The aim of this study was to evaluate the oral stereognosis and tactile sensibility in edentate subjects and relate these to patient age and capability of adaptation to new prostheses. A total of 67 patients were provided with new complete dentures 2-3 weeks before the experiment. In 54 subjects, the oral stereognosis was evaluated by 12 different test-pieces, which were placed unseen on the tongue and had to be recognized. In 38 patients, the oral tactile sensibility was determined in the premolar area using copper foils. The capability of adaptation was evaluated by a questionnaire. Denture retention was ass…
From algorithmic computing to direct retrieval: Evidence from number and alphabetic arithmetic in children and adults
1998
A number of theories of mental arithmetic suggest that the ability to solve simple addition and subtraction problems develops from an algorithmic strategy toward a strategy based on the direct retrieval of the result from memory. In the experiment presented here, 2nd and 12th graders were asked to solve two tasks of number and alphabet arithmetic. The subjects transformed series of 1 to 4 numbers or letters (item span) by adding or subtracting an operand varying from 1 to 4 (operation span). Although both the item and operation span were associated with major and identical effects in the case of both numbers and letters at 2nd grade, such effects were clearly observable only in the case of …
Dissociable contributions of left and right dorsolateral prefrontal cortex in planning.
2010
It is well established that the mid-dorsolateral prefrontal cortex (dlPFC) plays a critical role in planning. Neuroimaging studies have yielded predominantly bilateral dlPFC activations, but the existence and nature of functionally specific contributions of left and right dlPFC have remained elusive. In recent experiments, 2 independent parameters have been identified which substantially determine planning: 1) the degree of interdependence between consecutive steps (search depth) and 2) the degree to which the configuration of the goal state renders the order of single steps either clearly evident or ambiguous (goal hierarchy). Thus, search depth affects the actual mental generation and eva…
Stone-Free Rate after Treating Kidney Stones Exceeding 10 mm via Flexible Ureteroscopy: Can Endoscopic Assessment Replace Low-Dose Computed Tomograph…
2019
<b><i>Introduction:</i></b> It is unclear whether endoscopic assessment of the stone-free rate after flexible ureteroscopy (fURS) is as effective as assessment with low-dose computed tomography (CT) scan. <b><i>Methods:</i></b> Prospective documentation of patients with kidney stones &#x3e; 10 mm diameter from 2 different centers (Freiburg, Regensburg), who underwent fURS and were declared to be endoscopically completely stone-free. Low-dose CT control performed 4–8 weeks postoperatively. <b><i>Results/Conclusion:</i></b> Thirty-eight patients were treated between October 2015 and August 2016 (12 F, 26 M). Average a…
Picture naming yields highly consistent cortical activation patterns: Test–retest reliability of magnetoencephalography recordings
2020
Reliable paradigms and imaging measures of individual-level brain activity are paramount when reaching from group-level research studies to clinical assessment of individual patients. Magnetoencephalography (MEG) provides a direct, non-invasive measure of cortical processing with high spatiotemporal accuracy, and is thus well suited for assessment of functional brain damage in patients with language difficulties. This MEG study aimed to identify, in a delayed picture naming paradigm, source-localized evoked activity and modulations of cortical oscillations that show high test–retest reliability across measurement days in healthy individuals, demonstrating their applicability in clinical set…
