Long-term follow-up of children with risk organ-negative Langerhans cell histiocytosis after 2-chlorodeoxyadenosine treatment.

The nucleoside analogue, 2-chlorodeoxyadenosine (2CDA), was reported to be an active treatment for childhood Langerhans cell histiocytosis (LCH) without risk organ (RO-) involvement. However, we lack data on long-term effects of 2CDA treatment, including the disease reactivation rate, permanent sequelae and long-term tolerance. This study included 44 children from the French LCH registry, treated for a RO- LCH with 2CDA monotherapy (median number of six courses).

Evaluation of a web-based self-reporting method for monitoring international passengers returning from an area of emerging infection.

Objectives: Emerging infectious diseases are a public health issue of international concern. Identifying methods to limit their expansion is essential. We assessed the feasibility of a screening strategy in which each traveler would actively participate in the screening process after an intercontinental flight by reporting their own health status via a web-based self-administered questionnaire.

Evaluation of Venous Thromboembolism Recurrence Scores in an Unprovoked Pulmonary Embolism Population: A Post-hoc Analysis of the PADIS-PE trial.

Background: We aimed to validate the Men Continue and HERDOO2 (HERDOO2), D-dimer, age, sex, hormonal therapy (DASH), and updated Vienna recurrent venous thromboembolism prediction models in a population composed entirely of first unprovoked pulmonary embolism, and to analyze the impact of the addition of the pulmonary vascular obstruction index (PVOI) on score accuracy.

Methods: Analyses were based on the double-blind, randomized PADIS-PE trial, which included 371 unprovoked pulmonary embolism patients initially treated for 6 months, successively randomized to receive an additional 18 months of warfarin or placebo, and subsequently followed-up for 2 years.

Results: The HERDOO2, DASH, and updated Vienna scores displayed C-statistics of 0.

Role of MRI in the assessment of interbody fusion with tantalum intervertebral implant.

Introduction: Radiologic assessment of interbody fusion (IF) is controversial; thin-slice CT is the present gold standard despite artifacts due to the metal implant that hinder interpretation. The present study aimed to assess the contribution of MRI in IF assessment after instrumented posterior lumbar interbody fusion (PLIF) using tantalum intervertebral implants. The study hypothesis was that fusion following PLIF can be assessed on MRI.

Tantalum implants for posterior lumbar interbody fusion: A safe method at medium-term follow-up?

Introduction: Intervertebral implants increase stability and improve results in lumbar interbody fusion (LIF). The aim of the present study was to assess clinical and radiological results of posterior lumbar interbody fusion (PLIF) using a tantalum intervertebral implant without associated interbody bone graft.

Materiel And Methods: A single-center retrospective study included 52 cases of single-level PLIF, using 2 tantalum intervertebral cages, without interbody bone graft: 42 for degenerative disc disease, 10 for isthmic spondylolisthesis.

Effect of Early Initiation of Varenicline on Smoking Cessation in COPD Patients Admitted for Exacerbation: The Save Randomized Clinical Trial.

Our main objective was to demonstrate that, in smoker patients hospitalised for Chronic Obstructive Pulmonary Disease (COPD) exacerbation, early initiation of varenicline during 12 weeks, combined with an intensive counselling, is associated with a higher continuous abstainers rate (CAR) at one year as compared to intensive counselling alone. In this multicenter, prospective, double-blind, randomised study, 81 smoking COPD patients hospitalised for an acute exacerbation for at least 24 h were allocated to receive either varenicline ( = 42) or placebo ( = 39) for 12 weeks, in association with an intensive counselling in the 2 groups, and followed up for 40 weeks. The primary outcome was CAR at week 52.

Predictors for Residual Pulmonary Vascular Obstruction after Unprovoked Pulmonary Embolism: Implications for Clinical Practice-The PADIS-PE Trial.

Background:  We aimed to identify risk factors for residual pulmonary vascular obstruction after a first unprovoked pulmonary embolism (PE).

Methods:  Analyses were based on data from the double-blind randomized "PADIS-PE" trial that included 371 patients with a first unprovoked PE initially treated during 6 uninterrupted months; all patients underwent baseline ventilation-perfusion lung scanning at inclusion (i.e.

Multicenter validation of the flow measurement of classical monocyte fraction for chronic myelomonocytic leukemia diagnosis.

Peripheral blood monocytes include three subsets defined by CD14 and CD16 surface markers. An increase in the CD14CD16 classical monocyte fraction ≥ 94% of the total monocytes was proposed to rapidly and efficiently distinguish chronic myelomonocytic leukemia from reactive monocytosis. The robustness of this assay required a multicenter validation.

Incidence and risk factors for clinical neurodegenerative Langerhans cell histiocytosis: a longitudinal cohort study.

Neurodegenerative (ND) complications in Langerhans cell histiocytosis (LCH) are a late-onset but dramatic sequelae for which incidence and risk factors are not well defined. Based on a national prospective registry of paediatric LCH patients, we determined the incidence rate of clinical ND LCH (cND-LCH) and analysed risk factors, taking into account disease extent and molecular characteristics. Among 1897 LCH patients, 36 (1·9%) were diagnosed with a cND-LCH.

[What is the best management for a spermatic cord sarcoma in 2018?].

Spermatic cord sarcomas are rare tumors for which the most important is the initial diagnostic procedure. They are frequently misdiagnosed after surgery for inguinal hernia, inguinal lymphadenectomy or testicular malignancy. Any clinical suspicion has to lead to perform imaging with MRI and a core needle biopsy in order to obtain an accurate preoperative diagnosis.

[Risk factors for thromboembolic disease in young women-the role of hormones].

Unlabelled: Hormonal exposure in young women increases the risk of venous thromboembolic disease (VTE). Thrombophilia testing is often proposed in women of childbearing age before the initiation of contraception. However, the presence of a familial history of VTE has the potential to be more accurate than the presence of inherited thrombophilia.

Characteristics and outcome of multidrug-resistant tuberculosis in a low-incidence area.

Objectives: To characterize multidrug-resistant tuberculosis (MDR-TB) patients treated in a low endemic area in France and to determine risk factors for resistance. We also analyzed the efficacy and tolerability of tuberculosis (TB) treatment.

Methods: Between 2002-2013, all MDR-TB patients diagnosed in western France (hospitals belonging to the GERICCO group) were retrospectively included, with a follow-up period running until 2016.

Diagnostic Yield of Next-generation Sequencing in Very Early-onset Inflammatory Bowel Diseases: A Multicentre Study.

Background And Aims: An expanding number of monogenic defects have been identified as causative of severe forms of very early-onset inflammatory bowel diseases [VEO-IBD]. The present study aimed at defining how next-generation sequencing [NGS] methods can be used to improve identification of known molecular diagnosis and to adapt treatment.

Methods: A total of 207 children were recruited in 45 paediatric centres through an international collaborative network [ESPGHAN GENIUS working group] with a clinical presentation of severe VEO-IBD [n = 185] or an anamnesis suggestive of a monogenic disorder [n = 22].

Risk factors for recurrent venous thromboembolism after unprovoked pulmonary embolism: the PADIS-PE randomised trial.

We aimed to identify risk factors for recurrent venous thromboembolism (VTE) after unprovoked pulmonary embolism.Analyses were based on the double-blind randomised PADIS-PE trial, which included 371 patients with a first unprovoked pulmonary embolism initially treated during 6 months who were randomised to receive an additional 18 months of warfarin or placebo and followed up for 2 years after study treatment discontinuation. All patients had ventilation/perfusion lung scan at inclusion ( at 6 months of anticoagulation).

Prenatal exposure to glycol ethers and cryptorchidism and hypospadias: a nested case-control study.

Objectives: Glycol ethers (GE) are oxygenated solvents frequently found in occupational and consumer products. Some of them are well-known testicular and developmental animal toxicants. This study aims to evaluate the risk of male genital anomalies in association with prenatal exposure to GE using urinary biomarkers of exposure.

Interendoscopist variability in proximal colon polyp detection is twice higher for serrated polyps than adenomas.

Aim: To assess the interendoscopist variability in the detection of colorectal polyps according to their location and histological type.

Methods: This study was a retrospective analysis of prospectively collected data from a regional colorectal cancer (CRC) screening program; 2979 complete colonoscopies from 18 endoscopists were included. Variability in performance between endoscopists for detection of at least one adenoma (A), one proximal adenoma (PA), one distal adenoma (DA), and one proximal serrated polyp (PSP) was assessed by using multilevel logistic regression models.

Langerhans cell histiocytosis: therapeutic strategy and outcome in a 30-year nationwide cohort of 1478 patients under 18 years of age.

The French national cohort of children with Langerhans cell histiocytosis (LCH) has included 1478 patients since it was established in 1983. LCH therapeutic strategies substantially changed in 1998, so we have divided the cohort into two 15-year periods. Starting in 1998, therapy duration increased from 6 to 12 months, repeated induction therapy was performed in cases showing a poor response to the first induction with vinblastine and steroids, and refractory disease in a risk organ (RO+) was treated with cladribine and cytarabine.
