A Rapid Cognitive and Motor Decline: A Case of Misdiagnosed Sporadic Creutzfeldt-Jakob Disease.

Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder that leads to rapid cognitive decline, dementia, and neurological deterioration. CJD has several forms, including sporadic CJD (sCJD), which accounts for most cases, and variant CJD (vCJD), linked to exposure to bovine spongiform encephalopathy (BSE or mad cow disease). The disease is caused by abnormal prion proteins, which damage the brain and lead to death.

Descending necrotizing mediastinitis.

Descending necrotizing mediastinitis (DNM) is a rare but severe life threatening complication of oropharyngeal infections. We report a young lady who had severe pharyngitis complicated by anterior neck infection that descended to the mediastinum causing necrotizing mediastinitis. The course of her illness was complicated with septic shock, acute kidney injury, tracheo-esophageal fistula, and critical illness polyneuropathy.
