XI. B, 1 Mendoza-Guazon: Case of Dipylidium Caninum 27 



In the annual report of the Sanitary Commissioner with the 

 Government of India for 1913 (Calcutta) Bothriocephalus latus 

 is recorded in 18 cases, Tasnia asiatica in 4, T. saginata in 

 21, and T. solium in 288, but no case of Dipylidium is recorded. 

 Reports from different places in China, published in the China 

 Medical Journal, . indicate that Tsenia infestation is rare and 

 that Dipylidium caninum is conspicuous by its absence. 



In the article "Medical conditions in the Torrid Zone," the 

 data for which were collected by the College of Medicine and 

 Surgery, University of the Philippines, in 1912, the tapeworm 

 was not found in American Samoa nor in Korea, and 99 per cent 

 of the intestinal worms in China were chiefly Ascaris. 



In Formosa J. P. Maxwell found only one case of T. solium 

 among 15,000 patients. (27) 



In the United States of America we have the classical report 

 and description of C. W. Stiles (2) of a child 16 months old at 

 Detroit, Michigan, in 1903, and that of W. A. Riley (4) in 1910 

 of a boy 11 years old, who was very fond of a bull terrier which 

 was later found to be infested with Dipylidium, caninum. 



In looking for new cases during recent years, the following 

 reports were interesting. Wood (28) reported the intestinal 

 parasites from the different laboratories in the southern part 

 of the United States and found 10 cases of T. saginata and 1,004 

 of Hymenolepis nana in 1912. 



In 1914 Judkins,(29) from 15,000 stool examinations in Texas, 

 found 71 cases of Hymenolepis nana, 67 of T. saginata, and 2 of 

 T. cucumerina. Of the last he states that they are rare and 

 have no clinical interest, except that children are probably 

 infected from fondling and kissing cats and dogs. 



In order to shorten this report, let me quote the various me- 

 moirs of Blan chard, (30) before the Academy of Medicine in 

 Paris, 1913, who collected 76 authentic cases and tabulated them 

 according to their geographical distribution.
