CASE P. 



DESCRIPTION OF THE CASE. 



Male; born May 10, 1894; single; no occupation; lost strength in Decem- 

 ber 1910; came under our observation September 1911; diagnosis of diabetes, 

 which was confirmed by his physician, in January 1911 ; died in coma November 

 5, 1911. 



Family history. Father and one sister well; mother in poor health; one 

 sister died at 2 months, cause unknown. No history of diabetes in the family. 



Past history. Measles. Always good health. As the family moved fre- 

 quently from place to place he was much retarded in his studies at school ; this 

 caused him much anxiety, and he consequently worked very hard. 



General history of the case. -In December 1910, at the age of 17, his health 

 failed, and the disease was diagnosed as diabetes in January 1911. He suffered 

 from numerous furuncles which did not yield to local treatment, or treatment 

 with vaccines. Worn out by these, the patient gradually failed, and suc- 

 cumbed to coma on November 5, 1911. 



Physical examination. Greatest weight, 49.9 kilos.; usual weight, 48.6 

 kilos.; January 1911, 45.8 kilos.; September 16, 1911, 42.1 kilos.; all weights 

 without clothing. Height, 173 cm. Acetone odor to breath. Examination 

 negative except for numerous furuncles, especially about the neck. 



Urine data. The quantity of urine in January 1911 was approximately 

 5,000 c.c. The sugar disappeared after treatment for a month, but then per- 

 manently returned. The reaction of the urine was acid throughout the period 

 of observation. The ammonia amounted to 3.3 grams shortly after the patient 

 came under observation in September 1911, rising to 6.5 grams October 14-15. 

 The acidosis was so considerable that no great restriction of diet was attempted. 

 The albumen never exceeded a very slight trace. The urinary record is given 

 in table 40.
