Modified seromuscular tube: serosa lined bowel wall imbrication as a continent outlet for continent cutaneous urinary diversion.
1999
Purpose: We created a simplified modification of the seromuscular tube technique for continent cutaneous urinary diversion. Materials and Methods: We applied a simplified modification of our seromuscular tube technique in 1 woman and 2 men with a mean age of 53 years in whom outlet failure developed after continent cutaneous urinary diversion, and in whom adiposity and postoperative adhesions rendered revision difficult. We constructed a continent outlet conduit by imbricating the whole bowel wall and suturing it into a tube. Results: At a followup of 4 to 13 months (mean 7) all 3 patients are completely continent without leakage. Catheterization is performed at 3 to 5-hour intervals (mean …
Solvable Extensions of Nilpotent Complex Lie Algebras of Type {2n,1,1}
2018
We investigate derivations of nilpotent complex Lie algebras of type {2n, 1, 1} with the aim to classify nilpotent complex Lie algebras the commutator ideals of which have codimension one and are nilpotent Lie algebras of type {2n, 1, 1}
Behavioral and Brain Measures of Morphological Processing in Children With and Without Familial Risk for Dyslexia From Pre-school to First Grade
2021
School-age reading skills are associated with and predicted by preschool-age cognitive risk factors for dyslexia, such as deficits in phonological awareness, rapid automatized naming, letter knowledge, and verbal short-term memory. In addition, evidence exists that problems in morphological information processing could be considered a risk factor for dyslexia. In the present study, 27 children at pre-school age and the same 27 children at first grade age performed a morphological awareness task while their brain responses were measured with magnetoencephalography. Our aim was to examine how derivational morphology in Finnish language, and concomitant accuracy and reaction times are associat…
The radial artery is larger than the ulnar.
2003
The radial artery is presently widely used as a bypass graft for coronary artery reconstruction. However, the traditional opinion that the ulnar artery is the larger forearm artery has been questioned.The internal diameters of the radial and ulnar arteries were measured at the wrist in postmortem angiograms of 24 cadavers. Differences in mean values of variables between ulnar and radial arteries were analyzed using the Wilcoxon test.The mean diameter of the radial artery was 28% larger than that of the ulnar artery in the right arm (p0.001) and 26% larger in the left arm (p0.001). In the right arm the radial artery was dominant in 20 of 24 cadavers (83%), the ulnar artery in 3 of 24 (13%), …
Lp(a) levels in patients undergoing aorto-coronary bypass surgery.
1992
The aims of this study were to evaluate plasma lipid, apoprotein and Lp(a) levels in patients with severe coronary atherosclerosis undergoing aorto-coronary bypass surgery (BP) and to relate these parameters to the involvement of one or more vessels. Seventy-seven male patients and 77 cardiovascular disease-free controls, matched for sex, age and body weight were studied. Higher triglyceride and apo B levels with lower HDL-cholesterol and apo A-I levels were found in BP patients in comparison with the controls. Lp(a) levels were slightly, but not significantly, increased. Moreover BP patients presented a significantly higher prevalence of HDL-cholesterol levels below 35 mg dl-1 (49.3% vs 22…
Long-Term Results of Ileocecal Continent Urinary Diversion in Patients Treated With and Without Previous Pelvic Irradiation
2002
Patients who receive pelvic irradiation may require urinary diversion to manage complications resulting from progressive malignancy or radiotherapy. The choice of urinary diversion is an important issue and remains controversial. We characterized the long-term outcome of urinary diversion with a continent ileocecal reservoir in patients who received pelvic irradiation versus those who underwent urinary diversion without previous irradiation.Continent urinary diversion with an ileocecal reservoir (Mainz pouch 1) was performed in 36 irradiated patients in a 9-year period. Morbidity, mortality, the reoperative rate and parameters associated with the surgical procedure were determined at a medi…
Cracking the Code : The Impact of Orthographic Transparency and Morphological-Syllabic Complexity on Reading and Developmental Dyslexia
2019
Reading is an essential skill in modern societies, yet not all learners necessarily become proficient readers. Theoretical concepts (e.g., the orthographic depth hypothesis; the grain size theory) as well as empirical evidence suggest that certain orthographies are easier to learn than others. The present paper reviews the literature on orthographic transparency, morphological complexity, and syllabic complexity of alphabetic languages. These notions are elaborated to show that differences in reading acquisition reflect fundamental differences in the nature of the phonological recoding and reading strategies developing in response to the specific orthography to be learned. The present paper…

Diagnostic accuracy of non-invasive tests for advanced fibrosis in patients with NAFLD : an individual patient data meta-analysis
2021
ObjectiveLiver biopsy is still needed for fibrosis staging in many patients with non-alcoholic fatty liver disease. The aims of this study were to evaluate the individual diagnostic performance of liver stiffness measurement by vibration controlled transient elastography (LSM-VCTE), Fibrosis-4 Index (FIB-4) and NAFLD (non-alcoholic fatty liver disease) Fibrosis Score (NFS) and to derive diagnostic strategies that could reduce the need for liver biopsies.DesignIndividual patient data meta-analysis of studies evaluating LSM-VCTE against liver histology was conducted. FIB-4 and NFS were computed where possible. Sensitivity, specificity and area under the receiver operating curve (AUROC) were c…
