Presentation
In this edition, the Pain and Pain Management section is now at the front of the book, since a large percentage of emergency department patients present with pain-related complaints. [books.google.de]
Because of the competitive nature of the immunoassay as well as the complexity of the mixture of cross-reacting cardiac glycosides present in the plant material, the measured apparent digoxin concentration is not linearly related to the cardiac glycoside [ncbi.nlm.nih.gov]
We compared two immunoassays (LOCI digoxin assay and iDigoxin assay) for rapid detection of convallatoxin if present in human serum. [readbyqxmd.com]

- Insomnia
She had no previous medical or cardiac history, with the patient stating that she tried a herbal remedy of boiled comfrey leaves for insomnia 18 hours before arrival to the department. [readbyqxmd.com]
Treatment
Digoxin Fab fragment treatment should be given if indicated. Fab Fragment Treatment Sheep-derived digoxin antibody Fab fragments reportedly are effective for some plant cardiac glycosides. [emedicine.medscape.com]
The treatment of oleander poisoning is empirically based on the treatment of digitalis glycoside toxicity and consists of supporting the patient hemodynamically. [roaic.eg.net]
Overdose can quickly become life-threatening and swift treatment is vital. The first-line treatment for cardiac glycoside poisoning is administration of digoxin-specific antibodies. [amboss.com]
Because cardenolides from these plants are structurally similar, acute poisonings are managed using similar treatments. [cochrane.org]
Specific Treatment The first priority in treatment is ensuring the patient has an adequate airway and breathing. Patients who are bradycardic can receive atropine 0.5 mg IV, although any response is likely to be transient and minimal. [clinicaladvisor.com]
Prognosis
In such cases, the prognosis may be adversely affected. However, fatalities have generally not been reported from Lily-of-the-Valley Plant Poisoning In general, toxicities are common situations in the emergency departments. [dovemed.com]
Prognosis The prognosis for acute digoxin toxicity directly correlates with the mortality. [clinicaladvisor.com]
Age-related differences in incidence AAPCC data from 2019 show the following age breakdowns for plant cardiac glycoside exposure [4] : Infants and children younger than 6 years - 52% Children aged 6-19 years - 18% Adults older than 19 years - 30% Prognosis [emedicine.medscape.com]
Etiology
Cardiac glycoside poisoning Etiology Digoxin overdose ( iatrogenic, by nonadherence to prescribed dosages or by ingestion of plants containing cardiac glycosides) Hypokalemia Renal failure Treatment with verapamil, diltiazem, amiodarone, and/or quinidine [amboss.com]
Etiology Exposure to plants containing glycosides can occur through ingestion of sap, berries, leaves, blossoms, or seeds, or of teas brewed from plant parts. Plant extracts also have been intentionally injected. [emedicine.medscape.com]
Alternative diagnosis If an adequate dose of digoxin immune Fab fragments has been administered and there is no change in the hemodynamics, one should consider searching for alternative etiologies. [clinicaladvisor.com]

Epidemiology In the 1780s, the foxglove plant (from which digoxin is derived) was used in the treatment of congestive heart failure. [clinicaladvisor.com]
Pathophysiology
Pathophysiology More than 200 naturally occurring cardiac glycosides have been identified. These bind to a site on the cell membrane, producing reversible inhibition of the sodium (Na+)-potassium (K+)-adenosine triphosphatase (ATPase) pump. [emedicine.medscape.com]
Pathophysiology Ingested cardioactive steroids (CAS) are approximately 80% bioavailable. However, toxicokinetics depends on multiple factors,... References 1. [link.springer.com]
Pathophysiology Digoxin, like other cardiac glycosides, inhibits the sodium-potassium-ATPase. This inhibition results in a rise in extracellular potassium and a rise in intracellular sodium. [clinicaladvisor.com]

Prevention
Centers for Disease Control and Prevention Poisoning Prevention is a resource offering tips for preventing poisonings at home, including those by pesticides and plants. [redfin.com]

To prevent further absorption, oral administration of activated charcoal is recommended if no contraindications exist. [emedicine.medscape.com]
Cardiac glycosides function by inhibiting the intercellular sodium-potassium pumps to prevent the extrusion of sodium. Raised sodium levels derange the action of the sodium-calcium pump leading to an increased intracellular calcium concentration. [sites.google.com]
