The first review on prenatal drug exposure and ocular malformation occurrence.

Even though a non-negligible portion of congenital eye anomalies has a clear genetic origin, an etiology is not found for most patients. Prenatal medication exposure is recognized to be involved in fetal malformations and several medications are specifically known to alter eye morphogenesis during embryonic development leading to congenital eye defects. We explored and reviewed the role of medications described in the genesis of ocular malformations, a role that has been little evaluated and probably still underestimated especially since several studies have shown the wide exposure of pregnant women to medication.

The EFEMEREYE Study: prenatal medication exposure and ocular anomaly occurrence in EFEMERIS health database.

Purpose: To describe ocular anomalies (OAs) in children and fetuses in a French general population, to estimate their prevalence, and to investigate a possible association between prenatal medication exposure and the occurrence of OA in utero or in early childhood.

Methods: We conducted a case-control study using the EFEMERIS cohort, a database containing pregnancies registered in Haute-Garonne and their outcomes. We collected OA descriptions of fetuses at the time of pregnancy termination or of children at birth and the results of eye examinations of children at 9 months and 2 years of age.

Real-time and non-invasive acute lung rejection diagnosis using confocal LASER Endomicroscopy in lung transplant recipients: Results from the CELTICS study.

Background And Objective: Traditionally, the diagnosis of acute rejection (AR) relies on invasive transbronchial biopsies (TBBs) to obtain histopathological samples. We aimed to evaluate the diagnostic yield of probe-based confocal laser endomicroscopy (pCLE) as a complementary and non-invasive tool for ACR screening, comparing its results with those obtained from TBBs.

Methods: Between January 2015 and April 2022, we conducted a retrospective study of all lung transplant recipients aged over 18 years at Toulouse University Hospital (France).

[The Paris System, 2022 edition: What is new?].

The second version of the Paris System for reporting urine cytology was published in 2022. It follows the first version of 2016, which was very successful and widely adopted by many cytopathologists from different countries. Thus, numerous publications using the Paris System have made possible to refine the criteria as well as discussing the limits.

Cytopathological analysis of salivary gland cancer: REFCOR recommendations by the formal consensus method.

Objective: To determine the indications for fine-needle cytology and the modalities of frozen section pathological analysis in the management of salivary gland cancer.

Material And Methods: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group according to the formal consensus method.

[Serous fluid cytopathology : International system: Ancillary studies for serous fluids and special considerations for peritoneal washings].

The International System for serous fluids cytopathology is a cytologic classification which purpose is to establish a consensus on diagnostic terminology. The exponential discovery of prognostic and theranostic molecular alterations in many cancers, particularly in advanced stages, led the authors to describe the indications and the feasibility of these new markers on cytological samples from serous effusions. The various immunocytochemistry techniques, FISH and those testing DNA and RNA are reported in regard to their ability to identify the main targets currently explored in routine practice.

Artificial intelligence to improve cytology performance in urothelial carcinoma diagnosis: results from validation phase of the French, multicenter, prospective VISIOCYT1 trial.

Purpose: Cytology and cystoscopy, the current gold standard for diagnosing urothelial carcinomas, have limits: cytology has high interobserver variability with moderate or not optimal sensitivity (particularly for low-grade tumors); while cystoscopy is expensive, invasive, and operator dependent. The VISIOCYT1 study assessed the benefit of VisioCyt for diagnosing urothelial carcinoma.

Methods: VISIOCYT1 was a French prospective clinical trial conducted in 14 centers.

[Serous fluid cytopathology: International system].

The International System for Serous Fluid Cytopathology is a cytologic classification which purpose is to establish a consensus on diagnostic terminology. Five diagnostic categories are proposed associated to an increased rate of malignancy and specific cytological criteria. The categories are reported as: (I) Non-diagnostic (ND), the cells are insufficient for interpretation; (II) Negative for malignancy (NFM), only benign cells are present; (III) Atypia of undetermined significance (AUS), the cells present mild atypia more likely to be benign, but a malignant process cannot be definitively excluded; (IV) Suspicious for malignancy (SFM), the cells are present with atypia or in a number suspect of malignancy but with insufficient ancillary studies to give a positive malignant diagnosis; (V) Malignant (MAL), the cytological criteria are absolutely and definitively malignant.

Artifacts and main lesions in fetal ocular histology.

Histological artifacts in fetal eyes can involve different tissues and can be related to mechanical or autolytic lesions, fixation, the cause of death or the cutting technique. Knowing the causes, effects and appearance of artifacts allow the minimization of the risk of avoidable artifacts and help distinguish them from "true" pathological lesions. We describe these different types of artifacts and specifically analyze their involvement in different tissue structures of the eye.

The autumnal lockdown was not the main initiator of the decrease in SARS-CoV-2 circulation in France.

Background: In response to the SARS-CoV-2 pandemic, governments have taken drastically restrictive public health measures with significant collateral effects. It is important to understand the impact of these measures on SARS-CoV-2 circulation. However, pandemic indicators lag behind the actual level of viral circulation and these delays are an obstacle to assessing the effectiveness of policy decisions.

Impact of Regorafenib on Endothelial Transdifferentiation of Glioblastoma Stem-like Cells.

Glioblastomas (GBM) are aggressive brain tumours with a poor prognosis despite heavy therapy that combines surgical resection and radio-chemotherapy. The presence of a subpopulation of GBM stem cells (GSC) contributes to tumour aggressiveness, resistance and recurrence. Moreover, GBM are characterised by abnormal, abundant vascularisation.

Severe placental lesions due to maternal SARS-CoV-2 infection associated to intrauterine fetal death.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause severe placental lesions leading rapidly to intrauterine fetal death (IUFD). From August 2020 to September 2021, in the pathology department of Toulouse Oncopole, we analyzed 50 placentas from COVID-19-positive unvaccinated mothers. The purpose of our study is to describe the clinicopathological characteristics of these placental damages and to understand the pathophysiology.

African Gene Flow Reduces Beta-Ionone Anosmia/Hyposmia Prevalence in Admixed Malagasy Populations.

While recent advances in genetics make it possible to follow the genetic exchanges between populations and their phenotypic consequences, the impact of the genetic exchanges on the sensory perception of populations has yet to be explored. From this perspective, the present study investigated the consequences of African gene flow on odor perception in a Malagasy population with a predominantly East Asian genetic background. To this end, we combined psychophysical tests with genotype data of 235 individuals who were asked to smell the odorant molecule beta-ionone (βI).

Translation reprogramming by eIF3 linked to glioblastoma resistance.

Intrinsic resistance to current therapies, leading to dismal clinical outcomes, is a hallmark of glioblastoma multiforme (GBM), the most common and aggressive brain tumor. Understanding the underlying mechanisms of such malignancy is, therefore, an urgent medical need. Deregulation of the protein translation machinery has been shown to contribute to cancer initiation and progression, in part by driving selective translational control of specific mRNA transcripts involved in distinct cancer cell behaviors.

[Salivary gland cytopathology: Milan system 2018].

The salivary glands cytology is one of the most challenging area in cytopathology because of the wide diversity of benign and malignant tumors also because of their heterogeneity. However, fine needle aspiration cytology, with magnetic resonance imaging, represents a first-line examination to guide a possible surgical procedure and its extent. An accurate diagnosis of a specific tumor is sometimes difficult to assess in cytology.

A 4-Year Retrospective Analysis of Salivary Gland Cytopathology Using the Milan System for Reporting Salivary Gland Cytology and Ancillary Studies.

The cytopathology of salivary glands presents major challenges due to the heterogeneity of benign and malignant neoplasms, which is reflected in the large range of WHO 2017 Classifications. Fine needle aspiration (FNA) of salivary gland tumours is still the favoured initial approach as it results in good sensitivity and specificity. The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) was published in 2018 and comprises seven categories.

Ionizing radiation induces endothelial transdifferentiation of glioblastoma stem-like cells through the Tie2 signaling pathway.

Glioblastomas (GBM) are brain tumors with a poor prognosis despite treatment that combines surgical resection and radio-chemotherapy. These tumors are characterized by abundant vascularization and significant cellular heterogeneity including GBM stem-like cells (GSC) which contribute to tumor aggressiveness, resistance, and recurrence. Recent data has demonstrated that GSC are directly involved in the formation of new vessels via their transdifferentiation into Tumor Derived Endothelial Cells (TDEC).
