Iatrogenic myelodysplastic syndrome complicating multiple sclerosis: A case report.

After 1.5 years of treatment with dimethyl fumarate (DMF) for multiple sclerosis, preceded 8 years earlier by intravenous (IV) cladribine and 1 year earlier by natalizumab, our patient developed myelodysplastic syndrome (MDS). The initial manifestation was a severe drop in absolute neutrophil and lymphocyte counts.

Clinical Reasoning: A 47-Year-Old Man With an Upper Respiratory Infection, Acute Confusion, Dysarthria, and Ataxia.

A patient presenting with acute confusion, dysarthria, and appendicular ataxia with gait instability warrants a broad differential including emergent consideration of acute ischemic or hemorrhagic stroke. Moreover, in acute to subacute presentations, a wide array of etiologies including infectious causes, toxins, or autoimmune conditions may be considered. This article features a 47-year-old man who presented acutely with confusion, severe dysarthria, left upper extremity dysmetria, and unsteady gait.

Targeted epidural blood patch through a catheter in the treatment of spontaneous intracranial hypotension.

Objective: Spontaneous intracranial hypotension (SIH) can be effectively treated by epidural blood patch (EBP) following the primary unsuccessful conservative therapy. Nevertheless, multi-site cerebrospinal fluid (CSF) leaks or those originating at the cervical or thoracic spine remain therapeutically challenging. Therefore, this study aimed to present our experience in the treatment of thoracic CSF leaks using epidural catheters for the EBP infusion.

LGALS3 (galectin 3) mediates an unconventional secretion of SNCA/α-synuclein in response to lysosomal membrane damage by the autophagic-lysosomal pathway in human midbrain dopamine neurons.

Numerous lines of evidence support the premise that the misfolding and subsequent accumulation of SNCA/α-synuclein (synuclein alpha) is responsible for the underlying neuronal pathology observed in Parkinson disease (PD) and other synucleinopathies. Moreover, the cell-to-cell transfer of these misfolded SNCA species is thought to be responsible for disease progression and the spread of cellular pathology throughout the brain. Previous work has shown that when exogenous, misfolded SNCA fibrils enter cells through endocytosis, they can damage and rupture the membranes of their endocytotic vesicles in which they are trafficked.

Clinical Features and Treatment Response in Immune-Mediated Small Fiber Neuropathy with Trisulfated Heparin Disaccharide or Fibroblast Growth Factor Receptor 3 Antibodies.

Objective: Novel antibodies to trisulfated heparin disaccharide (TS-HDS) and fibroblast growth factor receptor 3 (FGFR-3) have been recently described in otherwise cryptogenic small fiber neuropathy (SFN) cases. Our goal was to further describe clinical features in such cases and to analyze treatment responses.

Methods: In a retrospective analysis, 40 cases of cryptogenic SFN in a university neuropathy clinic were identified.

Dual-Energy Computed Tomography in Loosening of Revision Hip Prosthesis: A Comparison Between MARS and non-MARS Images.

Purpose: The aim of the study was to assess potential endoprosthesis loosening in patients after revision total hip arthroplasty, based on monochromatic dual-energy computed tomography (DECT) images obtained with and without metal artifact reduction software (MARS) and comparison with the clinical examination and hip function.

Materials And Methods: Twenty-five consecutive patients underwent DECT examinations. Two monochromatic data sets were generated: with MARS (75-keV MARS) and without MARS (140-keV non-MARS) and evaluated for signs of loosening, using a dedicated radiological score.

Interest in Babies Negatively Predicts Testosterone Responses to Sexual Visual Stimuli Among Heterosexual Young Men.

Men's testosterone may be an important physiological mechanism mediating motivational and behavioral aspects of the mating/parenting trade-off not only over time but also in terms of stable differences between mating-oriented and parenting-oriented individuals. In this study, we tested the hypothesis that self-reported interest in babies is inversely related to testosterone reactivity to cues of short-term mating among heterosexual young men. Among 100 participants, interest in babies was related to a slow life-history strategy, as assessed by the Mini-K questionnaire, and negatively related to testosterone responses to an erotic video.
