Contraception
|July 10, 2012
Summary
Implanon® contraceptive implant insertion can cause nerve injury, leading to forearm pain and numbness. Proper technique and anatomical knowledge are crucial to prevent complications with subdermal implants.
Area of Science:
- Contraception
- Neurology
- Surgical Complications
Background:
- Etonogestrel contraceptive implant (Implanon®) is a long-acting subdermal hormonal method.
- Effective for women seeking reversible contraception.
Observation:
- A case of forearm pain and hypoesthesia occurred post-Implanon® insertion.
- Symptoms resulted from direct implant contact with the medial cutaneous nerve.
Findings:
- Improper insertion technique can lead to nerve injury.
- Correct anatomical understanding is vital for safe implantation.
Implications:
- Subdermal contraceptive implant insertion requires careful technique to avoid nerve damage.
- Nexplanon®, a successor to Implanon®, features an improved applicator for accuracy.

01:20Antiepileptic Drugs: Potassium Channel Activators
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.

01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:22Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
