Evaluation of temperature corrections for pesticide half-lives in tropical and temperate soils.

Temperature is a key factor that influences pesticide degradation. Extrapolating degradation half-lives (DT50) measured at a given temperature to different temperatures remains challenging, especially for tropical conditions with high temperatures. In this study, the use of the standard Arrhenius equation for correcting temperature effects on pesticide degradation in soils was evaluated and its performance was compared with that of alternative Arrhenius-based equations.

Association between binge eating disorder and psychiatric comorbidity profiles in patients with obesity seeking bariatric surgery.

Background: Eating disorders could be an important factor in the development of obesity, but psychiatric comorbidities are very heterogeneous in patients with obesity. Moreover, relationship between binge eating disorder and other psychiatric comorbidities is not clear. Our objective was to identify psychiatric comorbidity profiles of bariatric surgery candidates and to analyze the association between these profiles and binge-eating disorder.

Impact of Surgical Technique on Long-term Complication Rate After Laparoscopic Adjustable Gastric Banding (LAGB): Results of a Single-blinded Randomized Controlled trial (ANOSEAN Study).

Objective: The aim of the study was to explore the impact of the absence of band fixation on the reoperation rate and to identify other risk factors for long-term complications.

Background: Laparoscopic adjustable gastric banding has been demonstrated to permit important weight loss and comorbidity improvement, but some bands will have to be removed mainly for failure or in case of planned 2-step surgery. Then, the absence of a gastro-gastric suture (GGS) would allow easier band removal.

Prospective, multicenter, 3-year trial of laparoscopic adjustable gastric banding with the MIDBAND™.

Background: Although laparoscopic adjustable gastric banding (LAGB) is a popular metabolic/bariatric procedure, few prospective studies have assessed its outcomes. This study aimed to prospectively assess LAGB safety and effectiveness outcomes using the MIDBAND™ (MID, Dardilly, France).

Methods: Between May 2005 and September 2006, 262 morbidly obese patients underwent primary gastric banding with pars flaccida technique in 13 French medical centers.

[Dental implant news: from help to diagnosis to help to surgery].

Imaging has always been a part of dental implant procedures from its beginning. Initially, imaging was performed by dentists. The introduction of CT scan at the end of the seventies was revolutionary.

[Radical surgery in intrahepatic cholangiocarcinoma].

The aim of this retrospective study was to evaluate the results of surgical treatment of intrahepatic cholangiocarcinoma treated by the same team. Between 1988 and 2005, 75 patients underwent surgery for intrahepatic cholangiocarcinoma. There were 53 resections including three additional interventions for recurrence.

[Pregnancy after gastric banding: maternal tolerance, obstetrical and neonatal outcomes].

Objective: To define specific features of follow-up in pregnant women with gastric banding in order to evaluate obstetrical outcomes and gastric banding related complications.

Materials And Methods: A systematic review of observational and case-control studies, as well as case reports to discuss pregnant women follow-up.

Results: Seven articles were retained.

Prognostic factors after resection for hepatocellular carcinoma in nonfibrotic or moderately fibrotic liver. A 116-case European series.

The purpose of this study was to identify factors influencing prognosis after resection for hepatocellular carcinoma in the noncirrhotic liver and to measure the impact of moderate fibrosis on presentation and prognosis. A series of 116 primary procedures were performed for hepatocellular carcinoma in the noncirrhotic liver. These cases accounted for 42% of hepatic resections performed for hepatocellular carcinoma during the study period (1987-2005).

Resection of hepatocellular carcinoma with tumor thrombus in the major vasculature. A European case-control series.

Tumor thrombus in major vasculature is a frequent finding with a poor long-term prognosis in patients with hepatocellular carcinoma (HCC). The utility of surgical resection is still controversial. This study compared morbidity and survival after resection for HCC with and without tumor thrombus.

[Liver transplantation and living donors].

LIVER SPLITTING: Classically, cadaver livers are split ex situ to provide two grafts for transplantation. This procedure could be performed in situ, limiting the duration of the operation and improving recovery of liver function. LIVING RELATED DONORS: Living donor liver transplantation is a well established technique in children.

Effect of ischemia-reperfusion on bile canalicular F-actin microfilaments in hepatocytes of human liver allograft: image analysis by confocal laser scanning microscopy.

We studied and quantified the effect of ischemia-reperfusion on hepatic F-actin on bile canalicular and basolateral membranes in human liver allografts by means of confocal laser scanning microscopy imaging. The phalloidin-FITC staining of F-actin was normal in liver hepatocytes before reperfusion but decreased significantly after reperfusion (by 25% of controls). These results indicate that hepatic F-actin alteration is produced during the reperfusion phase.

Quantitative analysis of glycogen content in hepatocytes of human liver allograft after ischemia and reperfusion.

In order to examine glucose metabolism in liver grafts after cold ischemia and reperfusion, the heterogeneous lobular distribution pattern of glycogen content was studied using histochemical quantitative analysis. In most of the cases, this heterogeneous pattern of glycogen was observed after preservation and reperfusion. However, a 42% reduction of glycogen content, expressed as the ratio between stained surface and total surface of liver biopsies, was observed in biopsies after reperfusion.

Effect of ischemia-reperfusion on the heterogeneous lobular distribution pattern of glycogen content and glucose-6-phosphatase activity in human liver allograft.

In order to examine glucose metabolism in liver grafts after cold ischemia and reperfusion, the heterogeneous lobular distribution pattern of glycogen content and glucose-6-phosphatase activity was studied using histochemical methods. The characteristic heterogeneous lobular distribution pattern of glycogen and glucose-6-phosphatase was maintained after preservation and reperfusion. However, it appeared that glycogen content decreased in both periportal and centrilobular hepatocytes after reperfusion.

[Hepatocellular carcinoma in a non-cirrhotic liver. Presentation of series of 77 operated patients].

Objective: To present epidemiologic profile of this supposedly rare condition, its diagnostic management and the results of surgical treatment in a population of the mediterranean border.

Patients And Methods: Between 1987 and 1999, the records of patients operated on for hepatocellular carcinoma and in whom cirrhosis was not present on pathological examination of liver parenchyma were collected. Data were collected prospectively.

Morbidity of major hepatic resections: a 100-case prospective study.

Objective: To assess the morbidity and its main risk factors after major hepatic resection.

Design: Retrospective study of prospectively collected data.

Setting: University hospital, France.

[A fatal aorto-esophageal fistula due a foreign body: a foreseeable accident?].

Background: The ingestion of foreign bodies is the second most frequent cause of aorto-esophageal fistulization after aneurysms of the thoracic aorta.

Case Report: A 28-year-old man died from catastrophic hematemesis 7 days after ingesting a bone splinter. The CT scan performed 3 days before the fatal event had demonstrated a fistulous formation originating in the aorta.

[Liver transplantation in the adult: who and when to transplant?].

Introduction: The shortage of cadaveric organ donors imposes a severe limit to the number of liver transplantations. A selection is thus necessary among patients: should the sickest be selected, or those who supposedly have the best chance to survive and recover? Optimizing the timing of transplantation during the course of the disease (not too early, but not too late) is another issue.

Current Knowledge And Key Points: Suitable candidates for transplantation are patients suffering from an irreversible, symptomatic liver disease.

Inflammatory process complicating giant hemangioma of the liver: report of three cases.

Three cases of giant hemangioma of the liver associated with clinical and laboratory signs of inflammatory process, including low-grade fever, weight loss, abdominal pain, accelerated erythrocyte sedimentation rate, anemia, thrombocytosis, and increased fibrinogen level with normal white blood cell count are described. One patient presented with slight cholestatic jaundice because of tumor-related bile duct compression, but the other two patients had normal liver function tests, except for a slight increase in gammaglutamyl transferase. Clinical and laboratory abnormalities disappeared after surgical excision.

Intravenous leiomyomatosis with caval involvement: report of a case with radical resection and venous replacement.

Intravenous leiomyomatosis is a rare, histologically benign neoplasm that may be malignant in its specific tendency to intravascular extension. A case of intravenous leiomyomatosis with extension into the entire inferior vena cava in a 41-year-old woman is described. The patient was diagnosed with syncope 3 years after hysterectomy and was treated with a 1-stage procedure including venous replacement.

Pilot study on n-3 polyunsaturated fatty acids in the treatment of human experimental gingivitis.

The anti-inflammatory effect of n-3 PUFA on the gingivae has already been demonstrated in animal models. The aim of this double-blind, randomized pilot study versus placebo is to evaluate this action in human experimentally-induced gingivitis. For 14 days (D0-D14), 37 healthy volunteers practised intensive oral hygiene, then abstained from brushing their teeth for 21 days (D14 to D35).

[Polyunsaturated omega-3 fatty acids in the treatment of experimental human gingivitis].

The anti-inflammatory effect of omega-3 polyunsaturated fatty acids (n-3 PUFA) has already been demonstrated in an animal model. The aim of this randomized, double-blind, versus placebo study is to assess this action on experimental gingivitis in humans. Over a 14-day period (day 0-day 14), 37 healthy volunteers undertook intensive oral hygiene, and then did not brush their teeth for 21 days (day 14-day 35) so that gingivitis could then develop.
