Until now, the need for wide exposure and nonmanipulative dissection of pheochromocytoma has dictated the use of a large intraperitoneal transabdominal approach, which unfortunately results in a significant incidence of morbidity. A unilateral retroperitoneal approach guided by the refinements of new imaging techniques is less invasive but is associated with a small risk of incomplete cure. In one case report, we tested the hypothesis that laparoscopic surgery could combine the beneficial effects of both operative strategies without their respective side effects. We concluded that a laparoscopic approach combined with exclusive intraoperative infusion of nicardipine, a calcium-channel blocker, can be used to surgically remove pheochromocytoma under stable hemodynamic conditions. This provides better exposure of the anatomical structures than open surgery and allows a visual exploration of the entire abdominal cavity to exclude tumor multicentricity or ectopic sites in the case of inconclusive preoperative imaging investigations. Moreover, conversion to open surgery is always possible if needed. [less ▲]

BACKGROUND: Scientific evidence demonstrating interest in the laparoscopic approach for surgical repair of colonoscopic perforations is still lacking. The authors retrospectively reviewed the records of 43 patients who suffered from colonic perforations after colonoscopy between 1989 and 2008 in two tertiary centers in order to compare the results of the laparoscopic and the open approaches to repair. METHODS: The patients' demographic data, perforation location, therapy, and outcome were recorded from the medical charts. Forty-two patients were managed operatively (19 laparoscopies and 23 laparotomies). In three patients who underwent explorative laparoscopy, the procedure had to be converted to laparotomy due to surgical difficulties. The patients who underwent laparotomy management had a longer period between the colonoscopy and the surgery (P = 0.056) and more stercoral contaminations. RESULTS: The mean hospital stay was shorter for the laparoscopy group (P = 0.02), which had fewer postoperative complications (P = 0.01) and no mortality (NS). CONCLUSION: This series demonstrates that early laparoscopic management of colonoscopic perforation is safe. Laparoscopic management may lead to reduced surgical and psychological stress for the patient because of its low morbidity and mortality rates and shorter hospital stay. However, the procedure should be converted to a laparotomy if necessary. [less ▲]

PURPOSE: Nowadays laparoscopic colorectal surgery has demonstrated its advantages, including reduced postoperative pain, decreased duration of ileus, and shorter hospital stay. Few studies report results of laparoscopic surgery in complicated diverticulitis. This study was designed to analyze the results of laparoscopic sigmoidectomy in patients with fistulized sigmoiditis. METHODS: The authors retrospectively reviewed 16 patients who had laparoscopic sigmoidectomy for fistulized diverticulitis between 1992 and 2003 in a series of 247 laparoscopic colectomies. Eleven patients presented with colovesical, four with colovaginal, and one with colocutaneous fistulas; all were caused by sigmoiditis. The procedure always consisted of celioscopic sigmoidectomy with stapled transanal suture and, when indicated, closure of the cystic or vaginal fistula orifice. RESULTS: Mean age was 60 (range, 39-78) years. Mean number of episodes of diverticulitis before operation was three (range, 1-5). Mean time between the last episode and operation was 46 (range, 2-250) weeks. In our first three years of experience, three cases (18.7 percent) were converted to laparotomy. Reasons for conversion were the necessity for intestinal resection, splenectomy, and a wound of the anterior rectum. The mean operative time was 172 (range, 100-280) minutes. Mean hospital stay was 5.7 (range, 3-12) days. There was no mortality. Postoperative morbidity (2 patients, 12.5 percent) consisted of one pulmonary infection and one splenectomy. Long-term follow-up revealed no recurrence of diverticulitis and one incisional hernia. CONCLUSIONS: In experienced hands, laparoscopic sigmoidectomy may be a safe and effective procedure for fistulized sigmoiditis. [less ▲]

The use of laparoscopically assisted vaginal hysterectomy with or without annexectomy has been widely discussed. We report the technique of laparoscopic supracervical (subtotal) hysterectomy (LASH), which was first performed in 1990. Laparoscopic supracervical hysterectomy was carried out in a series of 36 women. The duration time was 60 min in experienced hands. There were no major complications. The feasibility and low morbidity rate of this laparoscopic approach led us to propose LASH in certain indications, particularly in cases of a uterus with multiple submucosal myomas where hysteroscopic therapy is less successful.

Reports of laparoscopy in heart graft recipients are scarce and, to our knowledge, laparoscopic colectomy has not yet been reported in heart transplant patients. The magnitude and the tolerance of the hemodynamic changes induced by pneumoperitoneum are unknown in heart graft recipients, who have a denervated heart and are "preload-dependent". The authors report the clinical courses of 2 heart graft recipients who developed acute diverticulitis without perforation or peritonitis and who underwent laparoscopic-assisted colectomy without complications.

La séduisante archéologue Lara Croft, protagoniste de la série de jeux Tomb Raider, est aujourd'hui l'une des icônes les plus célèbres du jeu vidéo, si bien qu'elle a même dépassé les limites de ce médium pour se faire connaître à un public élargi (à travers des adaptations au cinéma, en comics ou encore à travers des publicités). Toutefois, ce personnage est aussi une figure complexe qui a été reçue de manières très diverses : tantôt envisagée comme un symbole féministe (Lara Croft est une héroïne forte et indépendante, loin de la demoiselle en détresse à laquelle se cantonnaient généralement les premiers jeux vidéo), elle a aussi pu être interprétée comme une représentation caricaturale et réifiante de la femme. C'est donc d'un personnage chargé de contradictions que cette conférence propose de faire le portrait. [less ▲]

We present a summary of important computational issues and opportunities that arise from the use of semi-aggregate data (where the explanatory data for choice scenarios are not necessarily unique for each decision-maker) in discrete choice models. This data feature is commonly encountered with large transactional databases that have limited consumer information, such as itinerary choice modeling. We developed a software package called Larch, written in Python and C++, to take advantage of this kind of data to greatly speed the estimation of discrete choice model parameters. Benchmarking experiments against Stata (a commonly used commercial package) and Biogeme (a commonly used freeware package) based on an industry dataset for airline itinerary choice modeling applications shows that the size of the input estimation files are 50 to 100 times larger in Stata and Biogeme, respectively. Estimation times are also much faster in Larch; e.g., for a small itinerary choice problem, a multinomial logit model estimated in Larch converged in less than one second whereas the same model took almost 15 seconds in Stata and more than three minutes in Biogeme. For more complex discrete choice models, such as the ordered generalized extreme value model, estimation times were two seconds in Larch and four to five days in Biogeme. [less ▲]

Earlier systematic nonlinear treatments of parallel propagating electromagnetic waves have been given within a fluid dynamic approach, in a frame where the nonlinear structures are stationary and various constraining first integrals can be obtained. This has lead to the concept of oscillitons that has found application in various space plasmas. The present paper differs in three main aspects from the previous studies: first, the invariants are derived in the plasma frame, as customary in the Sagdeev method, thus retaining in Maxwell's equations all possible effects. Second, a single differential equation is obtained for the parallel fluid velocity, in a form reminiscent of the Sagdeev integrals, hence allowing a fully nonlinear discussion of the oscilliton properties, at such amplitudes as the underlying Mach number restrictions allow. Third, the transition to weakly nonlinear whistler oscillitons is done in an analytical rather than a numerical fashion. (C) 2005 American Institute of Physics. [less ▲]

Waves in electron-positron plasmas have fundamentally different dispersion characteristics due to the equal charge-to-mass ratios between negative and positive charges, which mix different timescales, and are of interest in understanding aspects of pulsars and active galactic nuclei, where astrophysical electron-positron plasmas occur. Earlier systematic nonlinear treatments of parallel propagating electromagnetic waves via a reductive perturbation analysis had indicated unusual results, namely a vector equivalent of the modified Korteweg-de Vries equation. The latter is nonintegrable except in the case of linear polarization when it becomes equivalent to the scalar (integrable) modified Korteweg-de Vries equation. Here large amplitude purely stationary nonlinear solitary waves are studied in their own reference frame via the McKenzie approach. The behavior of the wave magnetic field can be expressed through an energy integral that involves the Mach number of the structure. Possible solitons are super-Alfvenic and occur symmetrically for positive or negative fields, owing to the obvious symmetry between positive and negative charges with the same mass. The limits on the allowable Mach numbers and soliton amplitudes have also been computed. (C) 2004 American Institute of Physics. [less ▲]

Resolving the early diversification of animal lineages has proven difficult, even using genome-scale datasets. Several phylogenomic studies have supported the classical scenario in which sponges (Porifera) are the sister group to all other animals ("Porifera-sister" hypothesis), consistent with a single origin of the gut, nerve cells, and muscle cells in the stem lineage of eumetazoans (bilaterians + ctenophores + cnidarians). In contrast, several other studies have recovered an alternative topology in which ctenophores are the sister group to all other animals (including sponges). The "Ctenophora-sister" hypothesis implies that eumetazoan-specific traits, such as neurons and muscle cells, either evolved once along the metazoan stem lineage and were then lost in sponges and placozoans or evolved at least twice independently in Ctenophora and in Cnidaria + Bilateria. Here, we report on our reconstruction of deep metazoan relationships using a 1,719-gene dataset with dense taxonomic sampling of non-bilaterian animals that was assembled using a semi-automated procedure, designed to reduce known error sources. Our dataset outperforms previous metazoan gene superalignments in terms of data quality and quantity. Analyses with a best-fitting site-heterogeneous evolutionary model provide strong statistical support for placing sponges as the sister-group to all other metazoans, with ctenophores emerging as the second-earliest branching animal lineage. Only those methodological settings that exacerbated long-branch attraction artifacts yielded Ctenophora-sister. These results show that methodological issues must be carefully addressed to tackle difficult phylogenetic questions and pave the road to a better understanding of how fundamental features of animal body plans have emerged.
