ENTERALGIA IN LEAD COLIC. 



The periumbilical and epigastric pains of acute lead 

 poisoning, the constipation, the increase in blood pressure 

 (hypertensive crisis) are a real syndrome of stimulation 

 of the solar plexus (Laignel-Lavastine). 



MUCO MEMBRANOUS ENTERO COLITIS. 



This affection is characterized by three cardinal signs: 

 constipation, the presence of muco membranes and painful 

 crisis and are really an enteralgia of the abdominal sympa- 

 thetic. A. Mathieu has brought out the fact that in this 

 disease it is possible to illicit the various painful points of 

 the solar plexus. While there is spasm of the colon, the 

 maximum pain is near the umbilicus and can even be from 

 1 to 2 c.m. above it. The umbilical and superumbilical 

 pain is more marked when the examination is made during 

 the course of one of these painful attacks. 



"The intensity of the crisis," says Mathieu, "is measured 

 by the intensity of the pain on palpation in the median 

 line of the abdomen between the xyphoid and the 

 umbilicus." 



Next to muco membranous entero colitis can be consid- 

 ered as closely allied from a pathological point of view, 

 the painful intestinal attacks observed in uremic or oxalic, 

 or gouty patients (Loeper), the probable cause of which 

 is impregnation of the plexus with toxic substances. 



IV. PERIPHERAL SYMPATHETIC SYNDROMES. 



The following affections can be considered as such: 

 Raynaud's disease, erythromelalgia, angio-neurotic edema 

 and periodic intermittent hydrarthrosis. While the path- 

 ology of these conditions is still hypothetical the inter- 

 ference of the sympathetic does not appear to be doubtful
