AI Article Synopsis
- Gloriosa superba is a flowering plant found in South and Southeast Asia, known for causing self-poisoning due to its toxic compound, colchicine, which is mainly present in its seeds and tubers.
- A case study outlines a 28-year-old woman who developed delayed encephalopathy after consuming the tubers of G. superba.
- MRI scans revealed specific brain abnormalities, and the delayed onset of her symptoms is linked to the effects of colchicine on microtubular transport in the body.
Article Abstract
Gloriosa superba, a flowering plant widespread in South and Southeast Asia, is implicated in many cases of self-poisoning. Colchicine is concentrated in the seeds and tubers and this mediates its toxicity. We describe a 28-year-old woman who developed delayed encephalopathy after eating G superba tubers. MR scan of brain showed bilateral symmetrical T2 basal ganglia hyperintensities in the caudate and lentiform nuclei. The delay in onset of encephalopathy is attributable to a direct-effect colchicine, probably mediated through its effect on microtubular transport.

Altered protein conformation can cause incurable neurodegenerative disorders. Mutations in , the gene encoding neuroserpin, can alter protein conformation resulting in cytotoxic aggregation leading to neuronal death. Familial encephalopathy with neuroserpin inclusion bodies (FENIB) is a rare autosomal dominant progressive myoclonic epilepsy that progresses to dementia and premature death.

Food contamination with mycotoxin-producing fungi increases the risk of many diseases, including neurological diseases closely related to the neurotoxicity of these toxins. Based on the latest literature data, we presented the association of common mycotoxins with neurological diseases. Articles from 2001 to 2024 were analyzed.

Nova Scotia (NS) began offering CAR T-cell therapy as a third-line standard of care for eligible patients with relapsed or refractory large B-cell lymphoma (r/r LBCL) in 2022. Recipients of CAR T-cell therapy often experience acute toxicities, including cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), which require close monitoring and prompt management. This retrospective review aimed to describe the characteristics of adult patients with r/r LBCL deemed eligible to receive CAR T-cell therapy with axicabtagene ciloleucel in NS between January 2022 and June 2024, the toxicities experienced and toxicity management, hospital visits and intensive care unit (ICU) admissions, the utilization of toxicity management guidelines, and general efficacy outcomes.

Toluene intoxication constitutes a persistent public health problem worldwide. While most organs can be damaged, the brain is a primary target whether exposure is accidental, occupational, or recreational. Interventions to prevent/revert brain damage by toluene are curtailed by the scarce information on the molecular targets and mechanisms mediating toluene's brain toxicity and the common exposure to other neurotoxins and/or coexistence of neurological/psychiatric disorders.

Sarcopenia and hepatic encephalopathy (HE) are complications of chronic liver disease (CLD), which negatively impact clinical outcomes. Hyperammonemia is considered to be the central component in the pathogenesis of HE, however ammonia's toxic effects have also been shown to impinge on extracerebral organs including the muscle. Our aim was to investigate the effect of attenuating hyperammonemia with ornithine phenylacetate (OP) on muscle mass loss and associated molecular mechanisms in rats with CLD.
