is about fourteen days. Eruption follows the onset closely and reaches 

 its maximum intensity on the fifth day. It is during this five-day 

 period that there is greatest danger of infection. The disease seems 

 to be a general septicemia, the on.y discovery relative to its pathology 

 being the recovery from the spleen of an organism resembling the 

 Plotz organism. 



In the eradication of the epidemic the American Red Cross Sanitary 

 Commission employed such measures as fumigation of all hospitals, bar- 

 racks, schools and other foci of infection, bathing patients and steriliz- 

 ing their clothing, maintaining quarantine of patients, and the institu- 

 tion of measures of general sanitation. 



The treatment of typhus fever is unsatisfactory and is supportive 

 and symtomatic in character. The serum prepared by Nicolle, or the 

 vaccine prepared from the Plotz organisms tends to abort the disease 

 and apparently has therapeutic value. The prophylactic value of the 

 Plotz vaccine is problematic. — G. H. S. 



PROTOZOA AND OTHER ANIMAL PARASITES 



Trichinosis. Arthur R. Elliott. Jour. A. M. A., 1916, 66, 504.

 larvae were foimd in the spinal fluid. — G. H. S. 



Filaria Sanguinis Hominis. Codis Phipps. Journ. A. M. A., 1916, 



^^,266 



The author reports a case of infection with Filaria sanguinis hominis 

 {Filaria nocturua, Filaria bancrofii) in which a cure was effected by the 

 administration of salvarsan. — G. H. S. 



Dermatitis Herpetiformis. M. F. Engman and Robert Davis. Jour. 



A. M. A., 1916, 66, 492. 



It is probable that the endameba is an etiologic factor in a certain 

 percentage of cases of dermatitis herpetiformis. 



In such cases the administration of emetin hydrochloride has proved 

 of value.— G. H. S. 



Trichiniasis. Michael G. Wohl. Medical Record, 1916, 89, 98. 



A general review of the disease with the report of one case. 



In discussing methods of treatment, the author states that the admin- 

 istration of vaccines prepared from trichinae derived from infected hogs 

 would be a logical step, as specific antibodies have been demonstrated 

 in the blood of patients suffering from trichiniasis. — M. W. C.
