Implantable cardioverter-defibrillator. An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform cardioversion, defibrillation, and (in modern versions) pacing of the heart. The device is therefore capable of correcting most life-threatening cardiac arrhythmias.
Prescription Treatments. Nail fungi are small organisms that require warm moisture to survive, which means that they thrive inside shoes and socks. This makes toe fungus especially difficult to treat. Prescription treatments include the oral medications terbinafine and itraconazole.
Some of the treatments are affordable and others are expensive. These include oral medication, over-the-counter treatments, home remedies, and laser treatment. Now that you understand the causes of toenail fungus, you can take the necessary precautions to avoid it. This is particularly important if you are in a higher risk category due to age or the existence of another medical condition.
