Hare contended also that excessive intake of starch and sugar by inducing a state of “glycogenic distension” of the liver, might through compression of the intra-hepatic portal capillaries, lead to congestion of the retro-hepatic portal venous system, and sequentially of the gastric and intestinal mucosa. Through consequent inhibition of digestion and absorption, a condition of hyperpyræmia is induced. This, under varying conditions, may eventuate in acute gout, the coincident pyrexia of which is curative of the underlying hyperpyræmic state, and of all those hyperpyræmic manifestations (irregular or suppressed gout) which so often are the harbingers of an on-coming articular outbreak. NERVOUS THEORIES It may be noted _en passant_ that the influence of the nervous system was frequently invoked directly or indirectly in many of the theories already discussed. Stahl, it will be recalled, was the pioneer in this direction, and later Cullen and Henle propounded the view that “the origin of the affection was probably to be found in the central nervous system.” Gairdner, too, by implication, as also Laycock, postulated a neural origin for at any rate some of, the phenomena of gout. But it was reserved for Edward Liveing (1873) explicitly to advocate the nervous origin of the disease, his reflections on the paroxysmal nature of the attacks, its tendency to periodicity leading him to suspect its kinship with other neuroses. Those inclining towards the neural conception were later strengthened in their convictions by Charcot’s momentous identification of the nervous origin of certain arthropathies. Accordingly, in 1880, we find Sir Dyce Duckworth advocating the view that gout was “a primary neurosis,” “a functional disorder of a definite tract of the nervous system.” The gouty neurosis, Duckworth contended, may “be acquired, intensified, and transmitted; also that it may be modified variously and commingled with other neuroses; that it may suffer metamorphic transformations, or be altogether repressed.” Arguing by analogy, Duckworth saw in the paroxysmal attacks, the tendency to periodicity and alternation in the manifestations, evidence of an alliance between gout and the various neuroses. He further postulated that “this diathetic neurosis determined a disorder of nutrition and led to the perverted relations of uric acid and sodium salts in the economy.” He also held that the localisation of attacks, and the determination of urate of soda to the affected part was also due, in all probability to nervous influence. And the temporary renal incapacity for excretion of uric acid was also attributed by him to the same nerve inhibition.
