PIPAC in patients with peritoneal metastases from gastrointestinal tract (PIPOX01): An open label, non-comparative phase 1/2 dose escalation and expansion trial.

Background: Despite modern systemic chemotherapy, survival remains poor for patients with advanced isolated peritoneal metastases from the gastrointestinal tract. We aimed to assess the safety and efficacy of pressurized intraperitoneal aerosol chemotherapy (PIPAC) with oxaliplatin.

Patients And Methods: We conducted a phase 1/2, open label, non-comparative, dose escalation and expansion trial of PIPAC with oxaliplatin in patients with a peritoneal cancer index (PCI) of more than 5, 13 and 15 for respectively a gastric, small bowel and colorectal primary cancer, and who had received at least three months of systemic chemotherapy.

Modeling and Simulation as a Tool to Assess Voriconazole Exposure in the Central Nervous System.

Voriconazole is a triazole antifungal used empirically for the treatment of complicated meningitis associated with . Biopsy studies show that the drug exhibits adequate brain penetration although levels of cerebral spinal fluid (CSF) are highly variable. Considering that CSF is one of the main surrogates for CNS exposure, the present work proposed the building of a population pharmacokinetic modeling (popPK) model able to describing the exposure achieved by voriconazole in the plasma, interstitial cerebral fluid and CSF of healthy and infected rats.

Difficulties interpreting concentrations in fatal cases: example of 2,5-dimethoxy-4-chloroamphetamine.

Purpose: Death related to the use of drugs is evident when drugs are detected in biological matrices within toxic levels, but sometimes it can be less obvious. Intoxications after 2,5-dimethoxy-4-chloroamphetamine (DOC) use are occurring but up to date, only one fatality has been reported. Here we present the case of a young woman admitted to hospital as she presented vomiting, convulsions and cardiorespiratory arrest.

Molybdenum Occupational Study in a French Cohort of Workers.

Objectives: Occupational exposure to molybdenum has been poorly documented to date. Here, we present a retrospective study evaluating urinary molybdenum concentration before and after shift over a period of 2 years in exposed workers.

Methods: This retrospective study was conducted across eight industrial sites in France and included all workers undergoing medical follow-up for occupational molybdenum exposure.

High silver concentrations in biological samples following different exposures: Two case reports.

Background: Silver is used in various industrial applications, but also in confectioneries and for therapeutic use due to its antibiotic properties. Its toxicity is not well documented and most often only in the context of professional exposure.

Aim: Here we report two cases of high silver concentrations in biological samples in two women: the first patient presented grey marks around her cuticles, probably due to her consumption of silvered sweets and the second patient presented agranulocytosis and thrombocytopenia occurring within 24 h after the topical application of a cream containing sulfadiazine and silver to burns over a large surface area.

A fatal case after an intravenous injection of levamisole.

Levamisole is a drug originally prescribed as an antihelmintic. Because of the occurrence of severe cases of agranulocytosis and leukoencephalitis it was removed from the French market in 1998 for human use, while it remains available for veterinary use. Nowadays in France its only use in humans is regulated by authorization for temporary use for its immunomodulatory properties in the treatment of nephritic syndrome.

Baclofen self-poisoning: Is renal replacement therapy efficient in patient with normal kidney function?

Aims: We aimed at assessing the effectiveness of renal replacement therapy in patients severely self-poisoned with baclofen and with normal kidney function.

Methods: A population pharmacokinetic model was built using analytical data extracted from 26 baclofen poisoning cases reported to a French Poison Centre: 8 patients underwent renal replacement therapy (RRT), 18 did not. In the RRT group, 2 patients suffered from kidney failure.

A phase I dose-escalation study of oxaliplatin delivered via a laparoscopic approach using pressurised intraperitoneal aerosol chemotherapy for advanced peritoneal metastases of gastrointestinal tract cancers.

Objective: The objectives were to define the maximum tolerated dose (MTD), safety profile and pharmacokinetics (PKs) of intraperitoneal oxaliplatin delivered by pressurised intraperitoneal aerosol chemotherapy (PIPAC) in patients with advanced peritoneal carcinomatosis from gastrointestinal tract cancers.

Methods: PIPAC was applied every 4-6 weeks, for 5 cycles, in a phase I dose-escalation study using a 3 + 3 design. The first dose level was 90 mg/m with planned increases of 50 mg/m per level.

Identification of the origin of infantile saturnism based on lead isotopic and elemental ratios.

Background: In France, the prevalence of childhood lead poisoning is becoming rare since the avoidance of lead in paints in 1949 and the gradual replacement of water pipes. Chronic lead toxicity is well known and is well correlated to blood lead concentration.

Aim: Here we report a case of severe lead poisoning occurring in a young female child with a pica behavior.

Correction to: Clinical Practice Guidelines for Childbearing Female Candidates for Bariatric Surgery, Pregnancy, and Post-Partum Management after Bariatric Surgery.

In the original article, due to an XML tagging error the name of Véronique Taillard was omitted from the list of members of the French Study Group for Bariatric Surgery and Maternity (the BARIA-MAT Group). The correct list is as follows.

Pitfalls of toxicological investigations in hair, bones, and nails in extensively decomposed bodies: illustration with two cases.

It is difficult to carry out toxicological investigations in biological samples collected from extensively decomposed bodies and to interpret obtained results as several pitfalls should be considered: redistribution phenomena, degradation of xenobiotics during the postmortem period, contamination by putrefaction fluids, and external contamination. This work aims to present two cases in order to illustrate and discuss these difficulties in this tricky situation. Case#1: the body of a 30-year-old woman was found in a wooded area (1 month after she has been reported missing by her family): hair and a femur section were sampled.

Prognostic significance of the renal resistive index in the primary prevention of type II diabetes.

The renal resistive index has been demonstrated to predict the progression of renal disease and recurrence of major cardiac events in high-risk cardiovascular patients, in addition to other comorbidities. We aimed to assess the prognostic significance of the renal resistive index in type 2 diabetic patients for primary prevention. From 2008 to 2011, patients with type 2 diabetes underwent cardiovascular evaluation, including renal resistive index assessment by renal Doppler ultrasound.

Clinical Practice Guidelines for Childbearing Female Candidates for Bariatric Surgery, Pregnancy, and Post-partum Management After Bariatric Surgery.

Emerging evidence suggests that bariatric surgery improves pregnancy outcomes of women with obesity by reducing the rates of gestational diabetes, pregnancy-induced hypertension, and macrosomia. However, it is associated with an increased risk of a small-for-gestational-age fetus and prematurity. Based on the work of a multidisciplinary task force, we propose clinical practice recommendations for pregnancy management following bariatric surgery.

Bismuth Concentrations in Patients Treated in Real-Life Practice with a Bismuth Subcitrate-Metronidazole-Tetracycline Preparation: The SAPHARY Study.

Introduction: A fixed-dose association of bismuth subcitrate, metronidazole and tetracycline (BMT) (Pylera, Allergan, NJ, USA) was made available in France in 2013 for the eradication of Helicobacter pylori. Due to a historical issue of bismuth encephalopathy, the French Health Authorities requested a study of blood and plasma bismuth concentrations with BMT in daily practice.

Aims: The aim of the study was to measure eventual bismuth accumulation and neurological toxicity in patients prescribed BMT.

Rethinking Alkylating(-Like) Agents for Solid Tumor Management.

Although old molecules, alkylating agents and platinum derivatives are still widely used in the treatment of various solid tumors. However, systemic toxicity and cellular resistance mechanisms impede their efficacy. Innovative strategies, including local administration, optimization of treatment schedule/dosage, synergistic combinations, and the encapsulation of bioactive molecules in smart, multifunctional drug delivery systems, have shown promising results in potentiating anticancer activity while circumventing such hurdles.

Clinical consequences related to a defective elimination of clobazam caused by homozygous mutated CYP2C19 allele.

Voluntary drug intoxication with benzodiazepines is common and in most cases without consequences. We report an interesting case of voluntary drug intoxication with clobazam (CLB) in a patient with a homozygous mutated genotype. A 63-year-old Caucasian man was admitted to an intensive care unit for voluntary drug intoxication with CLB (1200 mg) complicated by prolonged hospitalization (46 days).

Estimation of Unbound Carboplatin Clearance From Total Plasma Concentrations as a Means of Facilitating Therapeutic Drug Monitoring.

Background: Therapeutic drug monitoring of carboplatin is based on its unbound clearance (CLU) determined by Bayesian analysis on unbound (U) concentrations. However, the ultrafiltration of plasma samples presents technical and time constraints. Therefore, this study aims to estimate CLU using total plasma (P) concentrations.

Hybrid Gd/cisplatin cross-linked polymer nanoparticles enhance platinum accumulation and formation of DNA adducts in glioblastoma cell lines.

Glioblastoma is the most frequent and aggressive primary malignant tumor of the central nervous system with a gloomy prognosis. Platinum derivatives and one among them, cisplatin, exhibited promising results when locally administered into the brain of glioblastoma bearing rats. Nanovectorization of anticancer agents through polymeric nanoparticles may even promote drug accumulation within cells, thus concentrating the drug efficiently at its target.
