Prospective study of long-term neurological sequelae of acute methanol poisoning
Kotíková, Kateřina ; Zacharov, Sergej (advisor) ; Pohanka, Miroslav (referee) ; Ehler, Edvard (referee)
Background: Methanol is widely industrially used alcohol with known neurotoxic properties. Bilateral necrosis of basal ganglia is a typical finding detected on MRI or CT scan of the brain in acute methanol poisoning. The impact of methanol exposure on peripheral nervous system is unknown. Aim: To study the prevalence and predisposing factors of haemorrhagic and non-haemorrhagic brain lesions in survivors of acute methanol poisoning; to investigate whether 123 I-ioflupane SPECT (DaT SPECT) has the potential as a marker of basal ganglia damage in acute methanol poisoning; to investigate the role of acute methanol exposure in the development of peripheral polyneuropathy (PNP) during the years following discharge from the hospital. Methods: A six year prospective, single-centre, cohort study of patients with confirmed methanol poisoning was conducted. The examination protocol consisted of neurological examination, including magnetic resonance imaging (MRI) of the brain, DaT SPECT and electromyographic examination, further, visual evoked potentials, ocular examination with retinal nerve fiber layer thickness measurement, series of biochemical and toxicological tests. In 46 patients, follow-up examinations including brain MRI were performed 3-8 and 24-28 months after discharge from the hospital, in 42...
