Introduction

Recently two of us reported on the treatment of the brittle nail with gelatin.¹ This study raised several questions requiring further investigation.

It was felt also that an attempt should be made to correlate other physiological changes in pathological nails. Specifically, the concept that blood levels of calcium, phosphorus, and/or the basal metabolic rate in pathological nails are disturbed, was challenged. This idea seems to have established itself firmly on the medical mind, in spite of the work of Kile² and others. A recent query on brittleness in nails was answered by giving calcium deficiency³ as the usual cause.
