Consensus statement by the French Society of Endocrinology (SFE) and French Society of Pediatric Endocrinology & Diabetology (SFEDP) on diagnosis of Cushing's syndrome.

Cushing's syndrome is defined by prolonged exposure to glucocorticoids, leading to excess morbidity and mortality. Diagnosis of this rare pathology is difficult due to the low specificity of the clinical signs, the variable severity of the clinical presentation, and the difficulties of interpretation associated with the diagnostic methods. The present consensus paper by 38 experts of the French Society of Endocrinology and the French Society of Pediatric Endocrinology and Diabetology aimed firstly to detail the circumstances suggesting diagnosis and the biologic diagnosis tools and their interpretation for positive diagnosis and for etiologic diagnosis according to ACTH-independent and -dependent mechanisms.

Intradural spinal cord arteriovenous shunts in a personal series of 210 patients: novel classification with emphasis on anatomical disposition and angioarchitectonic distribution, related to spinal cord histogenetic units.

Objective: Few classifications of intradural spinal arteriovenous shunts (ID-SAVSs) have considered their anatomical localization in relation to their phenotype and angioarchitectonics. The authors propose another vision of ID-SAVSs allowing a reappraised classification based on analysis of the anatomical disposition, angioarchitecture, and histogenetic location of these vascular malformations.

Methods: The radiological and clinical records of 210 patients with ID-SAVSs were retrospectively reviewed, considering their localization, vascular architectonics, and correlation with the 5 histogenetic units of the spinal cord.

Spinal cord arterio-venous shunts: From classification to therapeutic management.

Spinal Cord Arterio-Venous shunts (SCAVSs) are a rare disease. The aim of this paper is to describe how we classify and consider management of SCAVSs in relation to the location of the shunt focusing mainly on intradural SCAVSs. The anatomical features of the SCAVSs together with data provided by MRI and CT scans allow identification of four types of SCAVSs: paraspinal, epidural, dural and intradural ones.

A unique case of pure lateral spinal cord herniation.

Background: Spinal cord herniation (SCH) remains a challenging diagnosis for neuroradiologists and may require treatment challenging for neurosurgeons. Most cord herniations are usually found at anterior thoracic levels.

Clinical Presentation: A 28-year-old woman presented at our department with a 7-year history of progressive myelopathy.

[Therapeutic and endovascular management of cerebral mycotic aneurysms].

Infective endocardites are associated with both ischemic and hemorrhagic neurological complications and also with cerebral abscesses and the development of "mycotic" aneurysms, which are detected in about 5 % of patients in the acute and sub-acute phase of the infection. Data about their natural history and their hemorrhagic risk are scarce and fragmented. The therapeutic management is represented by the medical treatment of the infection with interventional abstention, the surgical treatment and the endovascular approach by selective embolization of the aneurysm.

Pangenomic Classification of Pituitary Neuroendocrine Tumors.

Pituitary neuroendocrine tumors (PitNETs) are common, with five main histological subtypes: lactotroph, somatotroph, and thyrotroph (POU1F1/PIT1 lineage); corticotroph (TBX19/TPIT lineage); and gonadotroph (NR5A1/SF1 lineage). We report a comprehensive pangenomic classification of PitNETs. PitNETs from POU1F1/PIT1 lineage showed an epigenetic signature of diffuse DNA hypomethylation, with transposable elements expression and chromosomal instability (except for GNAS-mutated somatotrophs).

Metabolomics and Communication Skills Development in Children; Evidence from the Ages and Stages Questionnaire.

We hypothesized metabolomic profiling could be utilized to identify children who scored poorly on the communication component of the Ages and Stages Questionnaire (ASQ); which assesses development in childhood, and to provide candidate biomarkers for autism spectrum disorders (ASD). In a population of three-year-old children, 15 plasma metabolites, were significantly ( < 0.05) different between children who were categorized as having communication skills that were "on schedule" ( = 365 (90.

Thrombectomy by Direct Cervical Access in Case of Common Carotid Occlusion with Collateral Supply to Internal Carotid Artery: Uncommon Anatomic Variant.

Background: Mechanical thrombectomy for acute ischemic stroke recently proved its superiority to standard medical management alone. With the increasing number of procedures, practitioners are exposed to unexpected situations that may lead to failure of access and significantly worse clinical outcome. Being able to plan the procedure and use alternative techniques may be useful in case of peculiar anatomy.

Efficacy of endoscopic endonasal transsphenoidal surgery for Cushing's disease in 230 patients with positive and negative MRI.

Object: The primary objective was to assess the remission rate, and the secondary objectives were to evaluate the early complications and recurrence rate and to define the predictive factors for the remission and recurrence rates.

Patients And Methods: This prospective single-center study included 230 consecutive patients, operated on by a single surgeon for Cushing's disease via a transsphenoidal endoscopic endonasal approach, over a 6-year period (2008-2013). The patients included in this series were all adults (>18 years of age), who presented with clinical and biological characteristics of Cushing's disease confirmed based on dedicated MRI pituitary imaging.

Predicting episodic memory formation for movie events.

Episodic memories are long lasting and full of detail, yet imperfect and malleable. We quantitatively evaluated recollection of short audiovisual segments from movies as a proxy to real-life memory formation in 161 subjects at 15 minutes up to a year after encoding. Memories were reproducible within and across individuals, showed the typical decay with time elapsed between encoding and testing, were fallible yet accurate, and were insensitive to low-level stimulus manipulations but sensitive to high-level stimulus properties.

Biological and radiological exploration and management of non-functioning pituitary adenoma.

Non-functioning pituitary adenoma may be totally asymptomatic and discovered "incidentally" during radiological examination for some other indication, or else induce tumoral signs with compression of the optic chiasm and pituitary dysfunction. Non-functioning adenomas are mainly gonadotroph, but may also be "silent". Treatment strategy depends on initial clinical, biological, ophthalmological and radiological findings.

Management of nonfunctioning pituitary incidentaloma.

Prevalence of pituitary incidentaloma is variable: between 1.4% and 27% at autopsy, and between 3.7% and 37% on imaging.

Pituitary MRI characteristics in 297 acromegaly patients based on T2-weighted sequences.

Responses of GH-secreting adenomas to multimodal management of acromegaly vary widely between patients. Understanding the behavioral patterns of GH-secreting adenomas by identifying factors predictive of their evolution is a research priority. The aim of this study was to clarify the relationship between the T2-weighted adenoma signal on diagnostic magnetic resonance imaging (MRI) in acromegaly and clinical and biological features at diagnosis.

Silent, but not unseen: multimicrocystic aspect on T2-weighted MRI in silent corticotroph adenomas.

Objective: Silent corticotroph adenomas (SCAs) present as nonfunctional pituitary tumours in routine pre-operative evaluation. The objective of this study was to evaluate the diagnostic accuracy of MRI T2-weighted sequences for detecting the corticotroph subtype pre-operatively.

Design: The pre-operative T2-weighted MRI sequences were retrospectively evaluated in patients with SCA and two control groups: clinically manifest corticotroph macroadenomas (CSMs) and nonfunctional gonadotroph macroadenomas (NFGMs).

MRI and MRA of spinal cord arteriovenous shunts.

The purpose of this review is to describe the diagnostic criteria for spinal cord arteriovenous shunts (SCAVSs) when using magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), and to discuss the extent to which the different MRI and MRA sequences and technical parameters provide the information that is required to diagnose these lesions properly. SCAVSs are divided into four groups according to location (paraspinal, epidural, dural, or intradural) and type (fistula or nidus); each type of lesion is described. SCAVSs are responsible for neurological symptoms due to spinal cord or nerve root involvement.

Advice and hints on imaging the lateral sellar compartments.

The lateral sellar compartment is a complex anatomical structure containing many different elements, any of which can be at the root of a pathological condition. MRI is the examination of choice for this region, and requires the use of specific protocols and systematic examination of each of these elements to produce a suitable diagnosis.

Follow-up of coiled intracranial aneurysms: comparison of 3D time-of-flight MR angiography at 3T and 1.5T in a large prospective series.

Background And Purpose: Our aim was to compare 3D TOF-MRA sequences at 3T and 1.5T in the follow-up of coiled aneurysms. The follow-up of coiled intracranial aneurysms is mandatory to depict potential recanalization.

Follow-up of coiled intracranial aneurysms: comparison of 3D time-of-flight and contrast-enhanced magnetic resonance angiography at 3T in a large, prospective series.

Objectives: To compare 3D-TOF magnetic resonance angiography (MRA) and contrast-enhanced MRA (CE-MRA) sequences at 3T in the follow-up of coiled aneurysms with digital subtracted angiography (DSA) as the gold standard.

Methods: DSA, 3D-TOF and CE-MRA were performed in a prospective series of 126 aneurysms in 96 patients (57 female, 39 male; age: 25-75 years, mean: 51.3 ± 11.

Developmental venous anomalies with capillary stain: a subgroup of symptomatic DVAs?

Introduction: Intracranial developmental venous anomalies (DVAs) are considered benign vascular dispositions; they are asymptomatic in the vast majority of cases. They represent extreme variations of the venous drainage and may rarely be responsible for focal venous ischemia leading to neurological dysfunction. The aim of the study is to analyze a group of patients with symptomatic DVAs with capillary stain at angiography.
