I am a 24-year-old woman with a five-month-old baby boy. I am still breastfeeding him exclusively. At Tipat Halav (the family health center), I was told to give him an iron supplement. But later, I thought that iron should not be given soon after or before milk. Is this relevant for breast milk as well? Should I give the iron drops a certain time after nursing him?

Prof. David Branski, chairman of the pediatrics departments at Hadassah University Medical Centers in Jerusalem, replies:
Yes - breast milk is a kind of milk. You should wait about 30 minutes after nursing him to give him the iron, as the calcium in milk combines with the iron and reduces its efficacy.
I am a 55-year-old man taking 5 milligrams of prednisone daily to control an asymptomatic autoimmune liver condition I was diagnosed with. As my liver enzymes, platelets and hemoglobin become irregular when I don't take this cortisone drug, my doctor says I should take the low dose. I don't suffer from any side effects from the drug, but I worry about the long-term. Are there any dangers in taking prednisone for years on end?

Prof. Jeffrey Aronson, a senior expert in the department of clinical pharmacology at Oxford University in the UK, comments:
All drug therapy depends on the balance of benefits and harms. Prednisone can be highly beneficial in autoimmune liver disease, but it can cause long-term adverse effects after three months of continuous treatment. The most important are hypertension, diabetes mellitus and osteoporosis. Monitoring the blood pressure and blood glucose concentration can give early warning of the first two. A bisphosphonate, such as alendronate, can prevent osteoporosis, but may not be necessary in those under 65, who are usually at a low risk of fractures. Lifestyle guidance for the prevention of osteoporosis includes a good dietary intake of calcium and vitamin D, regular exercise, stopping smoking, and avoiding excess alcohol. The dose is certainly small. However, the adverse effects are related to both dose and the duration of therapy. Thus, there are still long-term risks, even with low doses. For example, in one study, the relative risk of needing treatment for an increased blood glucose concentration was 1.77 at a dosage equivalent of prednisone of about 5 mg. per day. Some of the unwanted effects can be reduced by giving alternate-day therapy (e.g. 10 mg on alternate days), but in that case the beneficial effect may not be so marked.
I am a 52-year-old woman who is suffering from a fungus on my right big toe. About six years ago I had the same thing there, and it healed nicely with tea tree oil and a solution I got from a pharmacist. Today I cannot get that solution, and the fungus is not going away. I cut the nail down to almost nothing. I tried cyclamid, prescribed by the dermatologist, but it's not working. Now I am trying Mycroclear, and it's too early to tell if it's effective. What else can I do?

Dr. Julian Schamroth, a veteran Jerusalem dermatologist, replies:
Fungal infections of the toenails (onychomycosis) are characterized by crumbly nails, thickening of the nail plate, and various color changes. Onychomycosis of toenails is extremely difficult to treat; even physically removing the nail does not guarantee a cure, as the nail invariably gets reinfected as it regrows. There are many topical treatments available, such as nail paints, drops and creams. These, however, are only minimally effective. There are also numerous folk remedies including bleach, tea-tree oil, havdala wine, urine and the like, but although some people swear by them, I'm afraid there is no proof that they are effective.
The best method of treatment is oral therapy. There are several choices available, but patients should realize that it takes several months to effect a cure, it is not 100-percent effective (probably an 80-85% success rate), and even if successful, the fungus could come back. Griseofulvin (Grifulin Forte) and terbinafine (Lamisil) are administered daily for several months, whereas itraconazole (Sporanox or Itranol) is given daily as pulse therapy - one week per month for about three months. The efficacy of these drugs is probably much the same.
Many patients are reluctant to begin a long course of oral therapy, especially because they worry about liver damage. But oral drugs are very safe if the treatment is being monitored by the doctor. Some of these drugs can even be given to small children. A liver function test will be indicated during therapy, but in the vast majority of patients, this is merely a precautionary measure.
A new product - a topical solution called amorolfine (Loceryl) that is applied to the nails once per week - was recently launched here. It is not currently subsidized by the health funds and is somewhat expensive. For those patients who are reluctant to take oral therapy, this solution should be considered.
