Dr. Mark Falcon Lesses - two scientific articles

My grandfather, Dr. Mark Falcon Lesses, published a number of research articles over the year. In the same box with his certificate from the UJA in 1948, I found offprints of some of the articles. These are the first pages of two of them.

The first one, tititled "Hyperparathyroidism with Nephrolithiasis" (New England Journal of Medicine, 1949), is a case study of a young woman who suffered from a high fever and urinary tract infection. It turned out that she had kidney stones which were a consequence of hyperparathyroidism. One of the symptoms of hyperparathyroidism can be kidney stones because of the high calcium levels associated with this syndrome. She was in and out of the hospital, and treated unsuccessfully many times with antibiotics and removal of the kidney stones, until the misbehaving parathyroid was found and removed.

The second article is titled "Treatment of Thyroid Carcinoma with Radioactive Iodine (I 131)," from the American Journal of Medicine, 1951. I haven't read it yet so I can't provide my layperson's summary of it.
