A few days after a seafood meal a patient suffered ataxia and stupor. His examination revealed a confused patient with cerebellar signs and ocular disturbances (hypotropia). Blood results, cerebrospinal fluid and brain CT scan were unremarkable. The patient developed a septic shock and died 4 weeks after admission. No necropsy was performed. Questioning his family confirmed that he had eaten a shellfish meal a few hours before onset of the digestive signs. Trocas (Tectus pyramis) were definitely identified. The clinical picture strongly suggested a seafood poisoning, namely ciguatera. However, no toxicologic assay was performed. To our knowledge, this poisoning has never been reported with trocas. Nevertheless, the feeding habits of trocas would suggest similarity with ciguatera poisoning.

Background And Objectives: Breast cancers (BCs) of patients with paraneoplastic neurologic syndromes and anti-Yo antibodies (Yo-PNS) overexpress human epidermal growth factor receptor 2 (HER2) and display genetic alterations and overexpression of the Yo-onconeural antigens. They are infiltrated by an unusual proportion of B cells. We investigated whether these features were also observed in patients with PNS and anti-Ri antibodies (Ri-PNS).

Background: Migraine is a neurological disorder that is chronic and presents with episodes of paroxysmal features consisting of multiphase attacks of head pain, along with other symptoms related to neurological dysfunction such as sensitivity to movement, photophobia, phonophobia, nausea, and vomiting. Antiseizure medications are frequently used for the treatment of migraine. Of the antiseizure medications, sodium valproate and topiramate have received approval from the Food and Drug Administration (FDA) to prevent adult migraine.

Nystagmus has various clinical manifestations, including downbeat, upbeat, and torsional types, each associated with distinct neurologic features. Current rehabilitative interventions focusing on fixation training and optical correction often fail to achieve complete resolution. When nystagmus coexists with fragile X-associated tremor/ataxia syndrome (FXTAS), functional impairments worsen, particularly affecting balance.

Head and neck paragangliomas (HNPGLs) are typically slow-growing, hormonally inactive tumors of parasympathetic paraganglia. Inactivation of prolyl-hydroxylase domain-containing 2 protein causing indirect gain-of-function of hypoxia-inducible factor-2α (HIF-2α), encoded by EPAS1, was recently shown to cause carotid body hyperplasia. We previously described a syndrome with multiple sympathetic paragangliomas caused by direct gain-of-function variants in EPAS1 (Pacak-Zhuang syndrome, PZS) and developed a corresponding mouse model.

Introduction: The MAPT gene encodes Tau, a protein mainly expressed by neurons. Tau protein plays an important role in cerebral microtubule polymerization and stabilization, in axonal transport and synaptic plasticity. Heterozygous pathogenic variation in MAPT are involved in a spectrum of autosomal dominant neurodegenerative diseases known as taupathies, including Alzheimer's disease, Pick's disease, fronto-temporal dementia, cortico-basal degeneration and progressive supranuclear palsy.
