Non-convulsive status epilepticus versus periodic EEG pattern in sporadic Creutzfeldt-Jakob disease: two sides of the same coin?

Sporadic Creutzfeldt-Jakob disease is characterized by rapid cognitive and neuropsychiatric impairment. The Heidenhain variant of Creutzfeldt-Jakob disease is known for isolated visual disturbance that precedes other features. Periodic sharp wave complexes on EEG are typical of sporadic Creutzfeldt-Jakob disease, but at the onset, the electroclinical pattern may be unclear and suggest the hypothesis of a non-convulsive status epilepticus. Furthermore, non-convulsive status epilepticus and sporadic Creutzfeldt-Jakob disease could coexist simultaneously. We report the case of a patient admitted to our hospital for progressive psychiatric and cognitive disorders. In the initial phase, based on clinical, EEG, and neuroradiological features, a diagnosis of possible non-convulsive status epilepticus was made. Subsequently, the rapid neurological degeneration led to the diagnosis of Creutzfeldt-Jakob disease confirmed by cerebrospinal fluid real-time quaking-induced conversion. Non-convulsive status epilepticus could mimic Creutzfeldt-Jakob disease or be present in overlap. Antiseizure drugs may be started when the etiology is unclear, but overtreatment should be avoided when invasive treatment protocols fail, and the neurological progression suggests an encephalopathy.

Uncommon presentation of allergic bronchopulmonary aspergillosis during the COVID-19 lockdown: a case report.

BACKGROUND: During the ongoing pandemic of coronavirus disease 2019 (COVID-19), lockdown periods have changed the way that people and communities live, work and interact. CASE PRESENTATION: This case report describes an uncommon but important presentation of allergic bronchopulmonary aspergillosis (ABPA) in a previously healthy male, who decided to live in the basement of his house when Italy entered a nationwide lockdown during the COVID-19 pandemic. As high resolution computed tomography (HRCT) of the chest on admission showed diffuse miliary nodules, a miliary tuberculosis was initially suspected. However, further investigations provided a diagnosis of unusual presentation of ABPA. CONCLUSIONS: This case highlights the importance of maintaining awareness of Aspergillus-associated respiratory disorders during the COVID-19 pandemic, especially because lifestyle changes associated with home isolation carry an increased risk of exposure to mold spores present in some indoor environments.
