Diphtheria is, I believe, only a phase of albuminuria. Says Dr. Grasmuck, treating of diphtheria, and other physicians have observed the fact: “Another peculiarity of the scourge is its fondness for children of a certain condition——the fat, sleek, soft, tender, ‘well-fed’ children so generally admired——such children can offer but slight resistance to this disease; being, in fact, chronically diseased, they are predisposed to ‘attacks’ of all kinds; and, living to adult age, furnish the greater proportion of cases of tuberculous disease. On the other hand,” he continues, “I do not know of a single instance where the disease proved fatal to——rarely attacking——a child of the _genus_ ‘Street Arab’——children who spend most of their time out of doors, are thinly clad, sleep in cold rooms, have a spare diet, and who have no one to pamper them unwisely.” Dr. Dickinson treats of albuminuria under three heads, viz., tubular nephritis, granular degeneration, and lardaceous disease. He designates, also, such other diseases as are likely to result in consequence of this disorder; and finds some of these peculiar to, or more apt to afflict, sufferers from one or the other forms. He says: “It is seen (from the table presented) that nephritis is a disease of infancy and youth, causing most deaths in the first decade coincidentally with the prevalence of scarlatina; many in the third when the toils and exposures of active life are perhaps the most prolific of evil. Granular degeneration belongs to middle and advancing life, and is most fatal between fifty and sixty. The one flourishes upon the febrile accidents [!] of childhood and the susceptibilities of youth; the other develops when _the habits of life begin to tell_ and the effects of old age begin to appear. The lardaceous disorder has little to do with either extreme of the mortal course; it is chiefly associated with the _vices of early maturity_, and with tubercle and struma, disorders more incident to the young than the old, and in their suppurative form to youth rather than childhood.” Among the diseases resulting, or likely to result, from one or other forms of the disease, Dr. Dickinson names the following: dropsy, pneumonia, pleurisy, peritonitis, bronchitis [before mentioned]; pericarditis, endocarditis, hypertrophy of the heart, with cardio-vascular thickening, [heart “diseases”]; hemorrhagic accidents [bursting of blood-vessels——apoplexy] depending as they do upon structural changes of the vessels; diarrhœa. SOME OTHER SYMPTOMS. Nasal catarrh; the radical suppression of this discharge is likely to be followed by serious if not fatal kidney disease.[49] (To remove the former by removing its cause, thus rendering the discharge unnecessary, is quite another thing). Hence the danger of using so-called catarrh remedies, or of adopting any specific local treatment: they are either inert or injurious.
