Insights

An 84-year-old woman experienced a seizure and confusion while taking imipenem, a broad-spectrum antibiotic. This case highlights potential neurotoxicity associated with beta-lactam antibiotics, emphasizing the need for careful monitoring.

Area of Science:

  • Neurology
  • Pharmacology
  • Clinical Medicine

Background:

  • Beta-lactam antibiotics, including imipenem, are widely used for bacterial infections.
  • Neurotoxicity is a potential adverse effect of some antibiotics, particularly in vulnerable patient populations.

Observation:

  • An 84-year-old female patient presented with a confusional state.
  • The patient experienced a generalized tonic-clonic seizure during treatment with imipenem.
  • Electroencephalogram (EEG) revealed focal and generalized epileptiform discharges and a photoparoxysmal response.

Findings:

  • Imipenem, a beta-lactam antibiotic, was implicated in the patient's neurological adverse events.
  • Transient EEG changes, including epileptiform activity, were observed.
  • The patient's presentation suggests a potential link between imipenem and seizure activity.

Implications:

  • This case underscores the importance of recognizing and managing potential neurotoxic effects of imipenem.
  • Clinicians should consider antibiotic-induced seizures in patients presenting with unexplained neurological symptoms.
  • Further research may be warranted to elucidate the mechanisms of imipenem-induced neurotoxicity and identify risk factors.

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Cytotoxic Edema: Pathophysiology01:21

Cytotoxic Edema: Pathophysiology

Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
