John Rollo

[2] Rollo was frequently consulted about cases of diabetes, and in treatment had some success with the use of a nitrogenous diet.

[3] He was the first to take Matthew Dobson's discovery of glycosuria in diabetes mellitus and apply it to managing metabolism.

[7] By means of Dobson's testing procedure (for glucose in the urine) Rollo worked out a diet that had success for what is now called type 2 diabetes.

[8] The addition of the term "mellitus", distinguishing the condition from diabetes insipidus, has been attributed to Rollo.

[9] Rollo's diet for diabetic patients consisted of "milk, lime water, bread and butter, blood pudding, meat, and rancid fat".

[13] This kind of dietary management continued to the 1920s, being more successful for adults, who might survive some years, than for young patients who typically had only some months of life on it.

[14] Other collaborations of Rollo and Cruikshank related to treatments for syphilis involving acids, and published with the work on diabetes;[15][16] proteinuria; and strontium.
