THE SYMPATHETIC SYSTEM 199 



(b) Infectious Diseases. Renon and A. Delille have 

 studied the use of organo therapy in infectious diseases; 

 in particular, in severe typhoid associated with myocar- 

 ditis. In the majority of cases, the medication caused a 

 rapid rise in the blood pressure, a decrease in the tachy- 

 cardia and an increase in the diuresis. 



2. RADIOTHERAPY. It has been studied in France by 

 Beclere and Jaugeas in cases of acromegalia and gigantism. 

 In some cases treatment by the fronto temporal route has 

 given satisfactory results, which are worth describing: 

 arrest of growth of the extremities without, however, 

 any regression the re-appearance of the genital functions 

 and particularly, improvement of the visual disturbances, 

 depending of course on the treatment having been started 

 early enough, before optic atrophy. 



This treatment may be attempted in the syndromes due 

 to a diagnosed pituitary tumor. 



3. SURGICAL TREATMENT. Theoretically, this is the 

 best treatment in tumors of the pituitary. The removal 

 of the pituitary by the nasal route has given good results, 

 in spite of a high mortality. It is, however, only appli- 

 cable to those tumors which grow in the direction of the 

 sphenoidal sinus. 



In acromegalia in which the tumor surely is located in 

 the sella tursica, intervention has the greatest chance of 

 being successful. In certain cases there has been a 

 decrease of the signs of compression and even a regression 

 of the dystrophic disturbances (Toupet). 



In the adiposo-genitalis syndrome, the operative con- 

 ditions are not as satisfactory, for the variability of the 

 location of the lesions makes the detection of the tumor 

 and its removal very problematic. There are, however, 

 certain cases of simple adiposo-genitalis syndrome or 

 associated with acromegalia in which the symptoms have
