Dyskinesia-hyperpyrexia Syndrome (DHS) is a rare movement disorder emergency associated with Parkinson’s disease (PD), characterized by severe continuous dyskinesia accompanied by high fever and subsequent alterations in mental state. We present the case of a 74-year-old man with a nine-year history of PD who was admitted to the emergency room. He exhibited severe general dyskinesia, including myoclonus and chorea, along with a high fever and a stuporous mental state. Upon initial examination, a general myoclonic seizure associated with high fever was suspected. Consequently, the patient received hydration, antipyretic therapy, and sedative treatment. Upon the recovery of mental status, it was discovered that he had taken a higher dose of dopaminergic medication than usual on the day of his visit, as per his medical history. Subsequently, it was hypothesized that the severe dyskinesia, high fever, and loss of consciousness were related to this increased medication dosage. Therefore, his final diagnosis was DHS in PD. The dosage of dopaminergic medication was adjusted, and re-education was provided to the patient. This case report highlights the importance of recognizing DHS, as this patient was initially misinterpreted as having a generalized seizure due to severe dyskinesia and impaired mental state.

Abstract We report comparative catalytic studies of two types of commercial graphene nanoplatelets as electrode materials with different physical properties for Li–O2 batteries. The graphene nanoplatelets were characterized by field-emission scanning electron microscopy, transmission electron microscopy, N2 physisorption, X-ray photoelectron spectroscopy, and Raman spectroscopy. The electrochemical performance of the graphene nanoplatelets, which have large pore volume density, large pore diameter, and high population of defect sites, was evaluated using galvanostatic discharge–charge cycling and a depth-of-discharge test. Higher specific capacity of the Li–O2 battery was achieved when graphene nanoplatelets were used as an electrode material; this specific capacity could be associated with pore volume density, pore diameter, and number of defects in the graphene nanoplatelets.

Concomitant moyamoya syndrome and infratentorial arteriovenous malformation in a neurofibromatosis type 1 patient: a case report

Background: Neurofibromatosis type 1 (NF1) is a genetic disorder with diverse phenotypic manifestations. Cerebral vasculopathy is one of the multisystem involvements often overlooked unless symptomatic. Case Report: A 28-year-old male patient with prolonged NF1 complained of right-hand position-specific rhythmic tremor after surviving an ipsilateral cerebellar arteriovenous malformation (AVM) hemorrhagic transformation. Not only did he suffer rupture of the infratentorial vasculopathy but he also endured asymmetric supratentorial occlusive vessel changes in Moyamoya syndrome. Due to contralateral limb clumsiness, his right hemispheric vasculature was revascularized by encephaloduroarteriosynangiosis 13 years before the AVM rupture.Conclusion: This case report describes exceptional NF1 CNS involvement where the cerebral vasculature had concomitant Moyamoya syndrome and unilateral cerebellar AVM in a single patient. Cerebral vasculopathy should be surveyed and adequately addressed during the follow-up of chronic NF1, as it can cause irreversible sequelae or can be life-threatening.
