Ureteral injury during left colectomy for cancer: Laparoscopic management. A case report
2020
Abstract Introduction Iatrogenic ureteral lesions may occur after any abdominal and pelvic surgery. They are severe and can affect renal function and even vital prognosis. This study aimed to determine the clinical aspects and the therapeutic approaches of a lower third injury of the ureter during a laparoscopic left colectomy. Presentation of case An 81 year-old-man with left-sided colon cancer underwent laparoscopic left colectomy. During surgery there was a continuous full-thickness solution of the left ureter for which an end-to-end ureteral anastomosis was performed. In the postoperative period the patient underwent multiple urological and radiological interventional procedures due to …
Altemeier's procedure for complete rectal prolapse; outcome and function in 43 consecutive female patients.
2019
Background The aim of this retrospective study was to evaluate morbidity, mortality, postoperative function and recurrences in patients treated by Altemeier’s rectosigmoidectomy for complete rectal prolapse in a referral center for pelvic floor functional disorders. Methods Peri-operative data on 43 consecutive female patients were reviewed. At follow-up any change in pelvic floor function and recurrences were determined. Thirty four patients were assessed at a median interval of 49 (2–135) months, six being deceased for reason not related to the prolapse and three lost to follow-up. Results Post-operative complications at 30 days occurred in 18 patients (38%). Major complication occurred i…
Urethral recurrence of transitional cell carcinoma in a female patient after cystectomy and orthotopic ileal neobladder.
2000
A 63-year-old woman presented elsewhere with a unifocal pT1, G3 transitional cell carcinoma at the bladder base in 1995. She underwent urethral sparing cystectomy and ileal neobladder. Intraoperative frozen section from the proximal urethra did not demonstrate tumor involvement. Final histological examination revealed pT1, pN2, G3 transitional cell carcinoma. Adjuvant chemotherapy was not given. In 1998 the patient had symptoms of obstructive voiding due to a 3 3 3 cm. solid mass at the neobladder-urethra anastomosis (see figure). After 6 cycles of methotrexate, vinblastine, doxorubicin and cisplatin and a transient tumor size reduction, the patient was referred to us for local tumor progre…
Repetition without Repetition or Differential Learning of Multiple Techniques in Volleyball?
2021
A variety of approaches have been proposed for teaching several volleyball techniques to beginners, ranging from general ball familiarization to model-oriented repetition to highly variable learning. This study compared the effects of acquiring three volleyball techniques in parallel with three approaches. Female secondary school students (N = 42

ON-LINE CONSTRUCTION OF A SMALL AUTOMATON FOR A FINITE SET OF WORDS
2012
In this paper we describe a "light" algorithm for the on-line construction of a small automaton recognising a finite set of words. The algorithm runs in linear time. We carried out good experimental results on real dictionaries, on biological sequences and on the sets of suffixes (resp. factors) of a set of words that shows how our automaton is near to the minimal one. For the suffixes of a text, we propose a modified construction that leads to an even smaller automaton. We moreover construct linear algorithms for the insertion and deletion of a word in a finite set, directly from the constructed automaton.
Modélisation des choix d'itinéraires pédestres en milieu urbain. Approche géographique et paysagère
2006
Nowadays, on foot journeys create renewed interest as a complementary mode of transport. Indeed, local decision makers appear as willing to reduce the imbalance between different ways of transport within the cities. In the field of Geography the term ‘mobility' refers to the practice of exchanges and movements done by individuals or groups of individuals; this mobility is likely to reveal the characteristics of places and to contribute to their alteration. Among all the modes of transport, walking implies a privileged relation between persons and area they live in. As an element of the living environment used on a daily basis and eventually integrated by the prism of perception the visible …
On the Fundamental Period of Infilled RC Buildings
2015
This paper investigates the fundamental period of vibration of RC buildings by means of finite element macro-modelling and modal eigenvalue analysis. As a base study, a number of 14-storey RC buildings have been considered \"according to code designed\" and \"according to code non-designed\". Several parameters have been studied including the number of spans; the span length in the direction of motion; the stiffness of the infills; the percentage openings of the infills and; the location of the soft storeys. The computed values of the fundamental period are compared against those obtained from seismic code and equations proposed by various researchers in the literature. From the analysis of…
Desarrollo de nuevas estrategias en cromatografía líquida para el análisis de muestras complejas
2023
Desde los años 70, el uso de la cromatografía líquida de alta resolución (HPLC, High Performance Liquid chromatography) ha ido creciendo en los laboratorios analíticos, siendo actualmente la técnica de separación analítica más utilizada. Desafortunadamente, la eficacia suele ser menor que la que se logra en otras técnicas de separación como la cromatografía de gases y la electroforesis capilar. Esto restringe el análisis de muestras complejas. De ahí el gran esfuerzo dedicado a aumentar la eficacia y selectividad en HPLC, con importantes mejoras desde el inicio de la técnica. A pesar de los avances en las últimas décadas, con el desarrollo de instrumentación cada vez más sofisticada, y la m…
Recursion at the crossroads of sequence modeling, random trees, stochastic algorithms and martingales
2013
This monograph synthesizes several studies spanning from dynamical systems in the statistical analysis of sequences, to analysis of algorithms in random trees and discrete stochastic processes. These works find applications in various fields ranging from biological sequences to linear regression models, branching processes, through functional statistics and estimates of risk indicators for insurances. All the established results use, in one way or another, the recursive property of the structure under study, by highlighting invariants such as martingales, which are at the heart of this monograph, as tools as well as objects of study.
