Follicular Helper T-cell Lymphoma With Hodgkin/Reed-Sternberg-Like Cells Versus Classic Hodgkin Lymphoma: A Comparative Study.

Lymphomas of T-follicular helper origin (T-follicular helper-cell lymphoma [TFHL]) are often accompanied by an expansion of B-immunoblasts, occasionally with Hodgkin/Reed-Sternberg-like (HRS-like) cells, making the differential diagnosis with classic Hodgkin lymphoma (CHL) difficult. We compared the morphologic, immunophenotypic, and molecular features of 15 TFHL and 12 CHL samples and discussed 4 challenging cases of uncertain diagnosis. Compared with CHL, TFHL disclosed more frequent sparing of subcortical sinuses, high-endothelium venule proliferation, dendritic cell meshwork expansion, T-cell atypia, and aberrant T-cell immunophenotype.

Multi-Elemental Analysis of Edible Insects, Scorpions, and Tarantulas from French (Online) Market and Human Health Risk Assessment Due to Their Consumption: A Pilot Study.

Edible insects are becoming increasingly popular as protein alternatives to traditional animal-based products. As such, information on their elemental composition is important to ensure they are safe for human consumption. This article describes the development and validation of a rapid, reliable method for the simultaneous determination of 19 elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Pb, Se, Sr, and Zn) in edible insects by inductively coupled plasma mass spectrometry (ICP-MS) following closed vessel microwave digestion.

Target Product Profile for Cutaneous Neurofibromas: Clinical Trials to Prevent, Arrest, or Regress Cutaneous Neurofibromas.

Cutaneous neurofibromas (cNFs) are benign tumors of the skin that affect >95% of adults with neurofibromatosis type 1. Despite their benign histology, cNFs can significantly impact QOL due to disfigurement, pain, and pruritus. There are no approved therapies for cNFs.

French Neonatal Society issues recommendations on preventing nasal injuries in preterm newborn infants during non-invasive respiratory support.

Aim: To issue practical recommendations regarding the optimal care of nasal skin when non-invasive ventilation support is used.

Methods: We performed a systematic search of PubMed to identify relevant papers published in English or French through December 2019. Different grades of evidence were evaluated.

Heart Rate Control during Experimental Sepsis in Mice: Comparison of Ivabradine and β-Blockers.

Background: Tachycardia is a hallmark of sepsis. An elevated heart rate could impair ventricular filling and increase myocardial oxygen demand. β-Blockers and ivabradine (a selective inhibitor of If channels in the sinoatrial node) are both able to control sinus tachycardia, with the latter drug being devoid of negative inotropic effect.

Skin-reducing oncoplasty: A new concept and classification in breast cancer surgery.

Background And Objectives: Breast-conserving surgery and skin-sparing mastectomy are nowadays widely accepted as the standard of care in selected patients with early breast cancer. After an accurate review of the literature, it appeared that no ordered list of the numerous techniques described for conservative breast surgery has been established so far. The aim of this study was to develop a simple classification of the different skin incision patterns that may be used in breast surgery.

Contribution and limits of clinical specimens for the screening of intestinal multi-drug-resistant bacteria in view of laboratory automation.

The detection of multi-drug-resistant bacteria carriers constitutes a race against time for infection preventionists. Alongside standard analysis for diagnostic purposes and a rectal screening strategy, the authors tested a heavy-loaded selective method against 562 clinical specimens from 439 patients to detect extended-spectrum beta-lactamase-producing (ESBL) or carbapenemase-producing Enterobacteriaceae (CPE) and vancomycin-resistant enterococci (VRE). The approach identified five more specimens positive for ESBL-producing Enterobacteriaceae than standard analysis, and six out of nine known VRE/CPE carriers (three new CPE/VRE strains were also identified in this cohort).

Stenotrophomonas maltophilia healthcare-associated infections: identification of two main pathogenic genetic backgrounds.

Background: Stenotrophomonas maltophilia is an opportunistic multi-drug-resistant bacterium responsible for healthcare-associated infections. Strategies for in-hospital infection control and management of carriers and environmental reservoirs remain controversial.

Aim: To determine the population structure of S.

Psoas abscess and chronic Q fever: a contiguous or hematogenous complication? A case report and literature review.

Few cases of psoas abscesses (PA) during chronic Q fever have been reported, and the route of transmission remains unknown. Here, we report a new case and have performed a systematic literature review to determinate the spreading route of this complication. Medline, EMBASE and Web of Science were searched.

Brain injury unmasking Ehlers-Danlos syndromes after trauma: the fiber print.

Background: The role of physical trauma in the onset of symptoms in Ehlers-Danlos syndrome (EDS) has never been characterized. We sought to search and describe brain lesions EDS patients also having personal history of physical trauma. We systematically performed brain magnetic resonance imaging in a first cohort of patients with a hypermobility type of EDS which described the onset of their disease or its worsening after a physical trauma.

Laboratory-based strategy using a new marketed polymerase chain reaction assay to manage diarrheic episodes among patients from rehabilitation and long-term care facilities.

Management of Norovirus and Clostridium difficile gastroenteritis is challenging for rehabilitation and long-term care facilities. We evaluated the contribution of a 2-step laboratory-based strategy, including a new ready-to-use Norovirus polymerase chain reaction assay to promote isolation precautions. C difficile and Norovirus were successively identified from 17% and 23% of 52 episodes of diarrhea, respectively, during the winter season, leading to 100% adequate isolation measures.

Role of radiation therapy in non-melanoma cancers, lymphomas and sarcomas of the skin: Systematic review and best practice in 2016.

Radiotherapy (RT) has been used for the treatment of skin cancers since very early after the discovery of X-rays. Indications for radiotherapy in non-melanoma cancers are controversial, and are usually decided according to the tumor type and the possibility of curing the patient with surgery. The introduction of sophisticated surgery techniques and the information of the general population on potential late radiation-induced toxicity and carcinogenesis have led to limiting radiation indications in the dermatologist community.

Factors associated with postoperative complications in elderly patients with skin cancer: A retrospective study of 241 patients.

Objectives: The increasing frequency of skin tumors and longer life expectancy of the general population are likely to increase the frequency of dermatological surgery among elderly patients. The purpose of this study is to assess the rate of postoperative complications related to dermatological surgery in elderly patients and highlight the factors associated with these complications.

Methods: We conducted a retrospective monocentric study of patients aged >75 years who presented at our multidisciplinary consultation specialized for skin tumors from January 2008 to December 2010.

Distribution and antimicrobial susceptibility of bacteria from adults with community-acquired pneumonia or complicated skin and soft tissue infections in France: the nationwide French PREMIUM study.

The empirical therapy of community-acquired pneumonia (CAP) and complicated skin and soft tissue infections (cSSTIs) must be based on updated bacterial distribution and susceptibility data. A nationwide study consecutively collected 1288 isolates from CAP (n=467) and cSSTIs (n=821) from 18 French hospitals between 2012 and 2013. The MIC values of commonly used antimicrobial agents, including ceftaroline, were determined.

Patterns of practice of regional nodal irradiation in breast cancer: results of the European Organization for Research and Treatment of Cancer (EORTC) NOdal Radiotherapy (NORA) survey.

Background: Predicting outcome of breast cancer (BC) patients based on sentinel lymph node (SLN) status without axillary lymph node dissection (ALND) is an area of uncertainty. It influences the decision-making for regional nodal irradiation (RNI). The aim of the NORA (NOdal RAdiotherapy) survey was to examine the patterns of RNI.
