Under the term carotinemia, Hess and Myers1 described the occurrence of a peculiar yellow discoloration of the skin of the body with the presence of carotin, the characteristic pigment of carrots, in the blood of children fed on a diet containing carrots. We wish to report a similar occurrence in an adult, a case in which we were able to establish the casual relationship between diet and pigmentation, and to identify the offending pigment chemically, in a relatively large amount, in the blood.The yellow pigment carotin is not confined to carrots. It is included with xanthophylls under the general term carotinoids. They are widely distributed in nature, often in close association, and can be separated from each other on the basis of solubility. The yellow color of milk fats, corpus luteum and egg yolk, is due to carotinoids which are sometimes called lipochromes and again, lutein. Among human vegetable

Stiller1 devotes a whole chapter to the subject.Lawrason Brown has emphasized the fact that in no disease is the neurasthenic state so frequently encountered as in tuberculosis.It is not my intention to discuss the relationship between neurasthenia and clinically demonstrable tuberculosis, nor do I intend to consider the cases of clinically recognizable tuberculosis exhibiting neurasthenic symptoms.The purpose of this study is to present evidence to prove that:Many cases of clinically pure neurasthenia harbor tuberculous lesions so concealed as to escape detection by the examination methods usually employed.No organic disease except tuberculosis can be discovered in these cases.The diagnosis of tuberculosis rather than neurasthenia should be made in these cases.The nervous symptoms exhibited by these patients should be interpreted as a new clinical symptom type for tuberculosis produced by the toxin of the tubercle bacillus.In proof of this contention I here present

It seems to have been fairly well established that poor or insufficient food, per se, does not cause pellagra. The epidemiologic observations of Goldberger1 in 1914 furnish rather conclusive evidence that the disease is not bacterial in origin or transmissible by insect bites. To quote from Goldberger: "The investigations of the Public Health Service now permit one to answer the oft-repeated question: 'Is pellagra catching?' in the negative. No germ that can properly be considered the cause of the disease has ever been found. Attempts to give persons pellagra by inoculations of the blood, saliva, or other body discharges from several cases of pellagra have failed completely. . . . Furthermore, in an asylum where many of the inmates developed pellagra year after year, it was observed that the nurses and helpers who lived with them never developed the disease."The work of White2 and of Stannus3 in which both

Scattering angiomas (telangiectases) of the skin are frequently found in apparently normal persons and have no pathologic significance. On the other hand, they may develop in large numbers and in varying sizes on the skin of persons with diseases of the liver (cirrhosis and cancer), in chronic jaundice from gallstones, or simple catarrhal jaundice, also in tertiary lues (S. Ehrmann,1 Trawinski2), and as a result of Roentgen-ray skin exposure (Kingsbury3).A family form of multiple telangiectases of the skin and mucous membranes, with recurring epistaxis, has been described by Osler,4 and later by Hanes5 and Langmead.6In this group of cases the dilated capillaries are confined largely to the mucous membranes of the mouth and nose and the skin of the face. The tendency to recurring nasal hemorrhages is a prominent feature and there is an hereditary history of recurring hemorrhages in the family.An exceedingly rare form of generalized
