### input:
My elderly dad has extrememly dry cracked (were talking BIG cracks!), callouses everywhere... on his feet. Its no wonder he can barely walk. His nails are long, rock hard and havent been cut in years. He cannot reach his feet, so they go untreated. He rarely soaks them. I am not sure what I can do for him. He lives alone. I live 100 miles away, and he doesnt drive. So I can only go down for a day at a time and he wont be able to get to the doctors on a regular basis for treatment.  If I had one day, maybe 4 hours... what would you suggest I can do to at least ease his pain a little?

### output:

Hi, your elderly dad is having palmoplanter keratoderma with nail deformity. Give him vitamin A and vitamin E orally. Cap.isotretinoin 10 mg once a day may be given. If there is side effect like colitis, discontinue it. If there is itching antihistamines, like levocetirizine 5 mg daily may be given. If there is pain, nimesulide 200 mg twice delay for few weeks may be given. Tell him to keep the feet in salt water for 10 to 15 minutes daily. Give him salicylic acid point. 12 percent for rubbing on the soles twice a day. Tell him to keep the feet moist with moisturizer contains lactic acid and urea. You can trim the nails with big nail cutter after soaking the nails in salt water, it would be easy for you.... With this much treatment he will feel better. Still, you may consult dermatologist. Ok
