We describe a case of severe neuroexcitatory reaction with hyperthermia after administration of propofol in a 43-year-old patient suspected of a relapse of sarcoidosis who underwent bronchoscopy. This resulted in a lengthy stay in intensive care and long-term neuropsychological impairment. A review of the literature shows that severe neuroexcitatory symptoms (seizure-like phenomena, abnormal hypertonic, and/or jerky movements) occur rarely after propofol administration and may be life-threatening. Due to the paucity of data, the treatment is mostly empirical. The diagnosis can also be delayed owing to underrecognition. We conclude that health practitioners who frequently use propofol should be aware of this specific manifestation of drug toxicity, which albeit rare can be devastating for the patient.

Parkinson's disease (PD) is a complex multisystem disorder clinically characterized by motor, non-motor, and premotor manifestations. Pathologically, PD involves neuronal loss in the substantia nigra, striatal dopamine deficiency, and accumulation of intracellular inclusions containing aggregates of α-synuclein. Recent studies demonstrate that PD is associated with dysregulated metabolic flux through the kynurenine pathway (KP), in which tryptophan is converted to kynurenine (KYN), and KYN is subsequently metabolized to neuroactive compounds quinolinic acid (QA) and kynurenic acid (KA).

Functional somatic syndromes are increasingly diagnosed in chronically ill patients presenting with an array of symptoms not attributed to physical ailments. Conditions such as chronic fatigue syndrome, fibromyalgia syndrome, or irritable bowel syndrome are common disorders that belong in this broad category. Such syndromes are characterised by the presence of one or multiple chronic symptoms including widespread musculoskeletal pain, fatigue, sleep disorders, and abdominal pain, amongst other issues.

Propofol "frenzy" is considered a severe propofol-induced neuroexcitatory reaction involving nonepileptic spells of extremity thrashing, marked agitation, irregular eye movements, and impaired consciousness. Patients with propofol neuroexcitation present unique challenges for anesthesia providers due to underrecognition, lack of diagnostic tests, and differentiating from other comparable disorders that require medications that can exacerbate symptoms. We present a case of a healthy young patient whose postoperative course was complicated by propofol frenzy and functional limb paralysis following hip surgery with a spinal anesthetic and propofol sedation.

Objectives: Ketamine offers a plausible mechanism with favorable kinetics in treatment of severe ethanol withdrawal. The purpose of this study is to determine if a treatment guideline using an adjunctive ketamine infusion improves outcomes in patients suffering from severe ethanol withdrawal.
Design: Retrospective observational cohort study.
