Giant prolactinomas, rare in children, can have devastating endocrine, neurological and visual sequelae. Dopamine agonists (DA) are effective first-line therapy with few side-effects at doses usually used for prolactinoma treatment(1) , but higher-dose therapy for Parkinson's disease has well-recognized associations with impulse control disorders (ICD) including pathological gambling, impulsive eating, compulsive shopping and hypersexuality. Such associations are not well recognized with prolactinomas; to our knowledge this is the first reported case of hypersexuality in an adolescent receiving cabergoline for a giant prolactinoma...

Vitamin D deficiency (<20 ng/mL) and insufficiency (20-29 ng/mL) are common among patients with chronic kidney disease (CKD) or undergoing dialysis. In addition to nutritional and sunlight exposure deficits, factors that affect vitamin D deficiency include race, sex, age, obesity and impaired vitamin D synthesis and metabolism. Serum 1,25(OH)₂D levels also decrease progressively because of 25(OH)D deficiency, together with impaired availability of 25(OH)D by renal proximal tubular cells, high fibroblast growth factor (FGF)-23 and decreased functional renal tissue...

Neurodegenerative diseases progress slowly, creating increasing physical disability with unpredictable disease trajectories. The disease's life-threatening nature often places these patients in palliative care. There are several factors that complicate the care of patients with neurodegenerative diseases in palliative care units. Owing to physical impairments, there are many communication barriers between patients and staff. Nurses are not able to duplicate the patient's meticulous daily routine leading to caregiver mistrust in the nurse's competencies...

Astrocytes play a critical role in the development and homeostasis of the central nervous system (CNS). Astrocyte dysfunction results in several neurological and degenerative diseases. However, a major challenge to our understanding of astrocyte physiology and pathology is the restriction of studies to animal models, human post-mortem brain tissues, or samples obtained from invasive surgical procedures. Here, we report a protocol to generate human functional astrocytes from cerebral organoids derived from human pluripotent stem cells...

During this decade, breakthrough conceptual shifts have commenced to emerge in the field of Alzheimer's disease (AD) recognizing risk factors and the non-linear dynamic continuum of complex pathophysiologies amongst a wide dimensional spectrum of multi-factorial brain proteinopathies/neurodegenerative diseases. As is the case in most fields of medicine, substantial advancements in detecting, treating and preventing AD will likely evolve from the generation and implementation of a systematic precision medicine strategy...

Paraneoplastic neurological disorders (PNDs) are rare human autoimmune diseases that mostly affect the central nervous system (CNS). They are triggered by an efficient immune response against a neural self-antigen that is ectopically expressed in neoplastic tumors. Due to this shared antigenic expression, the immune system reacts not only to tumor cells but also to neural cells resulting in neurological damage. Growing data point to a major role of cell-mediated immunity in PNDs associated to autoantibodies against intracellular proteins...

Tuberous sclerosis complex (TSC) is a disease featuring devastating and therapeutically challenging neurological abnormalities. However, there is a lack of specific neural progenitor cell models for TSC. Here, the pathology of TSC was studied using primitive neural stem cells (pNSCs) from a patient presenting a c.1444-2A>C mutation in TSC2. We found that TSC2 pNSCs had higher proliferative activity and increased PAX6 expression compared with those of control pNSCs. Neurons differentiated from TSC2 pNSCs showed enlargement of the soma, perturbed neurite outgrowth, and abnormal connections among cells...

REVIEW
L Tatu, J Bogousslavsky
Neuropsychiatry had a profound impact on the life and work of one of the most influential French writers of the 20th century, Frédéric Sauser, better known by his pen name Blaise Cendrars (1887-1961). Cendrars, whose right writing hand was amputated after a battlefield wound in 1915, described with acuity his stump pain and phantom limb syndrome. He became a left-handed writer. Between 1956 and his death in 1961, he also suffered two strokes that progressively paralyzed his left side and greatly diminished his ability to speak...

REVIEW

Transient receptor potential vanilloid type 1 channel (TRPV1), as a ligand-gated non-selective cation channel, has recently been demonstrated to have wide expression in the neuro-immune axis, where its multiple functions occur through regulation of both neuronal and non-neuronal activities. Growing evidence has suggested that TRPV1 is functionally expressed in glial cells, especially in the microglia and astrocytes. Glial cells perform immunological functions in response to pathophysiological challenges through pro-inflammatory or anti-inflammatory cytokines and chemokines in which TRPV1 is involved...

Defective RNA metabolism is common pathogenic mechanisms involved in neurological disorders. Indeed, a conspicuous feature of some neurodegenerative diseases is the loss of nuclear activities of RNA-binding proteins (RBPs) like Fused in sarcoma (FUS) and eventually, their accumulation in cytoplasmic proteinaceous inclusions. Long non-coding RNAs (lncRNAs) are emerging as important regulators of tissue physiology and disease processes, including neurological disorders. A subset of these lncRNAs is the core of nuclear bodies (NBs), which are the sites of RNA processing and sequestration of specific ribonucleoproteins (RNPs) complexes...

INTRODUCTION: In-hospital stroke alerts are typically activated by nurses or physicians when a patient's neurological status acutely changes from baseline. It is unclear if knowledge of stroke symptoms translates to accurate activation of the acute stroke team. We hypothesized that nurses who activate the stroke alert system would correctly identify as great a proportion of acute strokes as physicians. We also investigated the time to activation of these in-hospital stroke alerts. METHODS: We retrospectively reviewed consecutive inpatient stroke team calls over a 12-month period at a single, tertiary care center...

Farber disease is a rare autosomal recessive disorder caused by acid ceramidase deficiency that usually presents as early-onset progressive visceral and neurologic disease. To understand the neurologic abnormality, we investigated behavioral, biochemical, and cellular abnormalities in the central nervous system of Asah1(P361R/P361R) mice, which serve as a model of Farber disease. Behaviorally, the mutant mice had reduced voluntary locomotion and exploration, increased thigmotaxis, abnormal spectra of basic behavioral activities, impaired muscle grip strength, and defects in motor coordination...

Conor Oliver, David J Timson
Triose phosphate isomerase (TPI) deficiency is a rare, but highly debilitating, inherited metabolic disease. Almost all patients suffer severe neurological effects and the most severely affected are unlikely to live beyond early childhood. Here, we describe an in silico study into well-characterised variants which are associated with the disease alongside an investigation into 79 currently uncharacterised TPI variants which are known to occur in the human population. The majority of the disease-associated mutations affected amino acid residues close to the dimer interface or the active site...

The precise assessment of pressure ulcer extension in patients with neurological diseases has crucial therapeutic implications, especially in the early detection of fistula to interior structures and osteomyelitis. Two case reports are presented on patients with a similar ischial ulcer, in whom an (18)F-FDG PET/CT study enabled a precise assessment of infectious complications in underlying tissues. These cases support the implementation of (18)F-FDG PET/CT as a first-line technique in their management.
