Doctors' Answers to "Frequently Asked Questions" - Fungus
Nail fungus (toenail)[posted
Answer: I haven't heard of this one. Currently the only ones that work are systemic pills.
Foot Fungus Prevention [posted
Answer: Keep her toes dry, use the medication topically 3-4 weeks after all superficial signs are gone and use a sterilizing spray in her bathroom to kill all remaining spores.
Ringworm Fungal Infections [posted
Answer: First, get a biopsy to see what you are treating. Second get a new doctor, a dermatologist would be find. The lamisil and sporanax are better drugs and might work fine, but, you need a diagnosis after this amount of time.
Identifying Possible Fungal Infection
Answer: Hard to tell without seeing it. Greenish discoloration would be very unusual for most skin fungal infections. You'll need a health professional to see the distribution, color, etc.
Stubborn Nail Fungus Treatment [posted
Answer: Sometimes methotrexate will work, but often nothing controls this problem.
Nail Fungus Treatment Preferences
Answer: Depends on the md and their philosophy. They all work about the same and have potential liver toxicity, cost can be a factor as well depending on patient resources. I usually use sporonox.
Answer: There are antifungals that will kill nail fungus infections. Since the toe nails take about 6 months to grow out there must be treatment for at least 6 months and often for one year. The original medications have the risk of liver toxicity and are rarely used. Newer medications like Sporonex are given for one to two weeks a month due to their ability to concentrate in the nailbed. They work better with less liver toxicity since there is a lower overall dosage. However, I rarely use them because these infections are only cosmetic. They will not spread to your body and will not cause other problems.
Answer: The two are probably separate. First, in treating the fungal infection of the foot you will need to apply the topical antifungal for 3 to 4 weeks after the infection is superficially gone. This is because the fungal spores will stay in the deep dermis until a compete layer of skin grows out (about 3 weeks). Then you need to ensure that your bath tub and anywhere that your feet are bare is free of fungal spores. Initially, this means twice a week cleaning with an antifungal preparation. If you use common showers like a health club wear shower shoes to keep your feet off the tiles. After the infection is clear apply the topical cream anytime you use the health club's shower. I'm not quite sure what the nasal infection is. Do systemic antibiotics help? Did the cortisone help?
Answer: The usual reason for return of ringworm is insufficient time taking the drug. A complete layer of skin must grow out before the infection will clear. This can take up to 4-6 weeks for most patients. Topical use of antifungals for extended periods will usually work.
Answer: There are a few funguses that grow on wood that could spread to people. These usually require being aerosolized by saw blades, etc. Casual contact would be extremely rare. The most usual fungus in this category is Blastomycosis dermatitis. Most infections are limited to the lung although they occasionally spread to other organs in the body. Infection is heralded by fever, cough, myalgia and malaise. Although I am aware of this disease I have never seen a case in 15 years of practice. As noted, most cases involve workers in wood factories who inhale the fungus after mechanical aerosolization.
Answer: There are new agents for fungal diseases being developed constantly.
However, none are immediately on the horizon for release. Thrush does not become
"resistant" to these drugs. However, recurring infections caused by underlying
medical conditions can cause repeat infections.
