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.
Apply an anti-fungal topical medication to the nail, nail bed and under the toenail. If the toenail has become very thick, visit a podiatrist to have the nail filed down some. Smoothing down the thick nail will make it easier for the skin under the nail to receive the medication.
