Chapter 3: IMPACT OF PRIMARY HYPERPARATHYROIDISM.

At present, primary hyperparathyroidism is most often discovered in an asymptomatic patient, but can sometimes be revealed by a renal or bone complications. In all cases, a full work-up is recommended, with assessment of renal function (glomerular filtration rate), 24-hour calciuria, screening for risk factors for lithiasis, and renal and urinary tract imaging (ultrasound or CT scan) to look for stones or nephrocalcinosis. Bone densitometry, with measurements of the spine, femur and radius, is the recommended reference test for demineralization.

Nanopore Sequencing as a Cutting-Edge Technology for Medulloblastoma Classification.

Background: Medulloblastoma (MB) is one of the most prevalent embryonal malignant brain tumors. Current classification organizes these tumors into four molecular subgroups (WNT, SHH, Group 3, and Group 4 MB). Recently, a comprehensive classification has been established, identifying numerous subtypes, some of which exhibit a poor prognosis.

Effect of oral nintedanib vs placebo on epistaxis in hereditary hemorrhagic telangiectasia: the EPICURE multicenter randomized double-blind trial.

Epistaxis greatly affects patients with hereditary hemorrhagic telangiectasia (HHT). Although few systemic treatment exist, nintedanib, is a good candidate thanks to its anti-angiogenic activity. Our main objective was to evaluate the efficacy of oral nintedanib on epistaxis duration in HHT patients with moderate to severe epistaxis.

Advanced Hybrid Closed Loop Algorithm Use in Type 1 Diabetes: The French MiniMed™ Glycemic Control and Quality of Life Study.

The MiniMed™ 780G Glycemic Control and Quality of Life (EQOL) study aimed to provide routine clinical practice data on system effectiveness and associated patient-reported outcomes (PROs) in France.

Methods: Individuals aged ≥ 7 years with T1D were enrolled.

Neuropsychological profile of French adults with early-treated phenylketonuria: a multicenter study.

Background And Objective: Adult patients with early-treated phenylketonuria (AwET-PKU) may present some subtle neurocognitive deficits. The aim of the study was to investigate 1) neurocognitive functions in a large group of AwET-PKU 2) the influence of plasma phenylalanine (Phe).

Methods: Participants: 187 AwET-PKU (classic PKU [cPKU] 81%, mild PKU [mPKU] 14%, and mild persistent hyperphenylalaninemia [MPH] 5%).

Evaluation of the analytic performance and macroprolactin sensitivity of a new prolactin immunoassay.

Purpose: Prolactin measurement is essential in endocrine diagnostics. Challenges such as the hook effect and reactivity to macroprolactin, which varies according to the reagent, complicate accurate measurement. The present study evaluated a newly marketed reagent to detect prolactin, IDS Prolactin, comparing it to an established reagent, Roche Elecsys Prolactin, assessing its behavior toward macroprolactin and polyethylene glycol (PEG) treatment, and establishing reference intervals.

Thyroidectomy without radioiodine in patients with low-risk thyroid cancer: 5 years of follow-up of the prospective randomised ESTIMABL2 trial.

Background: ESTIMABL2, a multicentre randomised phase 3 trial in patients with low-risk differentiated thyroid cancer (ie, pT1am or pT1b, N0 [no evidence of regional nodal involvement] or Nx [involvement of regional lymph nodes that cannot be assessed in the absence of neck dissection]), showed the non-inferiority of a follow-up strategy without radioactive iodine (I) administration compared with a postoperative I administration at 3 years post-randomisation. Here, we report a pre-specified analysis after 5 years of follow-up.

Methods: Patients treated with total thyroidectomy with or without prophylactic neck lymph node dissection, without postoperative suspicious findings on neck ultrasonography, were randomly assigned to the no-radioiodine group or to the radioiodine group (1·1 GBq-30 mCi after recombinant human thyrotropin-stimulating hormone).

Heterozygous BTNL8 variants in individuals with multisystem inflammatory syndrome in children (MIS-C).

Multisystem inflammatory syndrome in children (MIS-C) is a rare condition following SARS-CoV-2 infection associated with intestinal manifestations. Genetic predisposition, including inborn errors of the OAS-RNAseL pathway, has been reported. We sequenced 154 MIS-C patients and utilized a novel statistical framework of gene burden analysis, "burdenMC," which identified an enrichment for rare predicted-deleterious variants in BTNL8 (OR = 4.

Pulmonary Hypertension Associated With Trastuzumab-Emtansine: An Analysis of French PH Registry and WHO Pharmacovigilance Database.

Background: Trastuzumab emtansine has been recently suspected to be associated with the development of pulmonary arterial hypertension (PAH).

Research Question: Is there an association between trastuzumab, trastuzumab emtansine, or trastuzumab deruxtecan and the development of PAH?.

Study Design And Methods: Characteristics of incident PAH cases treated with trastuzumab, trastuzumab emtansine, or trastuzumab deruxtecan were analyzed from the French PH Registry, the VIGIAPATH program, concurrently with a pharmacovigilance disproportionality analysis using the World Health Organization pharmacovigilance database using a broad definition of pulmonary hypertension (PH) and a narrow definition of PAH.

Cystinosis metabolic bone disease: inflammatory profile in human peripheral blood mononuclear cells and derived osteoclasts.

Unlabelled: Cystinosis metabolic bone disease (CMBD) is an emerging concept in infantile nephropathic cystinosis, patients presenting with bone pains, fractures, and deformations during teenage or early adulthood. The underlying mechanisms remain unclear. Our aim was to explore the pro-inflammatory profile of osteoclastic lineage in cystinotic patients.

Is Carmustine Wafer Implantation in Progressive High-Grade Gliomas a Relevant Therapeutic Option? Complication Rate, Predictors of Complications and Onco-Functional Outcomes in a Series of 53 Cases.

: The aim was to determine the complication rate and the predictors of complications and survival in high-grade glioma surgically managed at progression with implantation of Carmustine wafers. : A retrospective series of 53 consecutive patients operated on between 2017 and 2022 was built. : The median age was 55 ± 10.

A French multicenter analytical evaluation of the automated Lumipulse G sNfL blood assay (Fujirebio®) and its comparison to four other immunoassays for serum neurofilament light chain assessment in clinical settings.

Objectives: Measurement of serum neurofilament light chain (sNfL) protein is becoming a key biomarker for many neurological diseases. Several immunoassays have been developed to meet these clinical needs, revealing significant differences in terms of variability and results. Here, we propose a French multicenter comparison of 5 sNfL assays.

Evaluation of general anesthesia protocols for a highly controlled cardiac ischemia-reperfusion model in mice.

Background: The aim of our study was to test different anesthetic mixtures in order to identify the most suitable one for a surgical cardiac ischemia-reperfusion model in mice.

Methods: 1) Sixty four mice were submitted to one of the 6 combinations of ketamine or alfaxalone associated to xylazine, medetomidine or midazolam. Depth and quality of anesthesia were evaluated via 5 reflex scores.

[Adult and pediatric thesaurismosis: Lysosomal, lipid and glycogen storage diseases].

Thesaurismosis or storage diseases are rare genetic disorders due to an abnormal accumulation of an organic compound or its metabolite within cells. These conditions are either secondary to a defect in catabolism caused by enzymatic dysfunction or to a deficiency in transport proteins. They encompass lysosomal storage diseases, lipid storage diseases or dyslipidemias, and glycogen storage disorders or glycogenoses.

[SFBC Working Group on sources of errors in laboratory medicine: objectives and key areas of work].

Laboratory medicine plays a crucial role in patient care, contributing to approximately 70 % of clinical decisions. In collaboration with clinicians, laboratory medicine specialists perform analyses that are useful for diagnosis, screening and prevention. Laboratories are known for their efficiency, which is reached through a rigorous quality system.
