Cefepime-Induced Nonconvulsive Status Epilepticus in a Pediatric Patient with Normal Renal Function.

Child Neurol Open 2022 Jan-Dec;9:2329048X221119575. Epub 2022 Aug 7.

Department of Pediatrics and Neurology, Penn State Health Milton S. Hershey Medical Center, Hershey, PA, USA.

Cefepime, a fourth-generation cephalosporin, is known to risk the induction of neurotoxic impairment from confusion to nonconvulsive status epilepticus (NCSE). Neurotoxic effects of cefepime are most commonly evident in the setting of impaired renal function in adults; however, are rarely present in those with normal renal excretion function or in the pediatric population. We present a case of a 16-year-old female with a complicated past medical history but no accounts of impaired renal function yet, after starting cefepime, presented with encephalopathy, intermittent stimulus-induced posturing, and was found to have NCSE.

Refractory Seizures Secondary to Vitamin B6 Deficiency in Parkinson Disease: The Role of Carbidopa-Levodopa.

Case Rep Neurol 2022 May-Aug;14(2):291-295. Epub 2022 Jun 27.

Department of Neurology, Icahn School of Medicine at Mount Sinai, New York, New York, USA.

Carbidopa-levodopa has been used for more than 50 years in the treatment of Parkinson disease (PD) and other movement disorders. Pyridoxal 5'-phosphate (PLP), an active form of vitamin B6 (pyridoxine), is involved in the decarboxylation of levodopa to dopamine; carbidopa, which is combined with levodopa to reduce peripheral levodopa conversion and minimize peripheral dopamine side effects, binds irreversibly with PLP. As a result, carbidopa-levodopa may cause vitamin B6 deficiency and associated sequelae, including seizures, especially in high doses. Read More

SARS-CoV-2 infection and seizures: the perfect storm.

J Integr Neurosci 2022 Jun;21(4):115

Department of Neurology, University of North Carolina, Chapel Hill, NC 27599-7025, USA.

Seizures have been increasingly identified as a neurologic manifestation of coronavirus disease 2019 (COVID-19) infection. They may be symptomatic due to systemic infections, as a result of direct central nervous system (CNS) invasion, or occur in response to inflammatory reactions to the virus. It is possible that proinflammatory molecules released in response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can lead to hyperexcitability and epileptogenesis, similar to infections caused by other neurotrophic viruses.

Seeking the Light in Intensive Care Unit Sedation: The Optimal Sedation Strategy for Critically Ill Patients.

Front Med (Lausanne) 2022 24;9:901343. Epub 2022 Jun 24.

Department of Medical and Surgical Specialties, Radiological Science and Public Health, University of Brescia, Brescia, Italy.

The clinical approach to sedation in critically ill patients has changed dramatically over the last two decades, moving to a regimen of light or non-sedation associated with adequate analgesia to guarantee the patient's comfort, active interaction with the environment and family, and early mobilization and assessment of delirium. Although deep sedation (DS) may still be necessary for certain clinical scenarios, it should be limited to strict indications, such as mechanically ventilated patients with Acute Respiratory Distress Syndrome (ARDS), status epilepticus, intracranial hypertension, or those requiring target temperature management. DS, if not indicated, is associated with prolonged duration of mechanical ventilation and ICU stay, and increased mortality. Read More
