Tour de Maitre (toor-de-matr) [Fr. , -'the master's 

 turn "]. A maneuver in passing the catheter in a fat 

 person. The surgeon stands on the right side of the 

 patient and introduces the catheter, with its convexity 

 upward, the shaft lying obliquely across the left thigh 

 of the patient, and as the point enters the bulb, the 

 handle is swept around toward the abdomen, when 

 the beak enters the membranous urethra and is 

 carried into the bladder by depressing the shaft be- 

 tween the patient's thighs. The sound may be intro- 

 duced into the uterus in an analogous manner, enter- 

 ing the instrument with the convexity upward, and 

 then sweep- 

 ing the shaft 

 around.

 turn]. An 

 instrument

 ling the cir- 

 culation by 

 means of 

 compres- 

 sion. It 

 usually con- 

 sists of two metallic plates united by a thumb-screw and

a strap provided with a pad. The strap is fastened 

 about the part, the pad being placed over the artery to 

 be occluded. The screw is placed diametrically op- 

 posite the pad, and the strap is tightened by separating 

 the metallic plates of the screw. T., Dupuytren's, 

 one for compressing the abdominal aorta, consisting of 

 a semicircle of metal with a pad at one extremity. T., 

 Esmarch's, consists of a stout, elastic rubber band 

 applied above the proximal turn of an elastic bandage 

 passing around the part to be rendered exsanguine. 

 T., Field, one consisting of a strap and buckle with a 

 pad to pass over the artery. T., Horse-shoe, one 

 shaped like a horse-shoe, to compress (by a screw) only 

 two points, and thus permit venous return. T., Lip, 

 one consisting of a U-shaped piece of steel, the arms 

 being provided with plates which are approximated by 

 a central screw. T., Provisional, one applied loosely, 

 so that it may be tightened at once upon the recur- 

 rence of hemorrhage. T., Signorini's. See '/'., 

 Horse-shoe. T., Skey's, also a modification of the 

 horse-shoe or Signorini's. T., Spanish Windlass, 

 a knotted bandage or handkerchief twisted by a stick 

 and used as a tourniquet. T., Torcular, same as T., 

 Spanish Windlass. 



Tous-les-mois (too-la-mwali) [F., "every month"]. 

 A variety of arrow-root starch prepared from Catina 

 edulis ; canna-starch. 



Toussaint's Theory. A theory as to the cause of im- 

 munity conferred by inoculation. After one attack of 

 a disease (e.g., anthrax) the lymphatic glands undergo 

 a hardening of their surrounding envelop, thus render- 

 ing them impervious to the after-entrance of infectious 

 agents by this, the usual, portal. 



Tow (to) [ME., to7t>, tow]. The refuse of flax or 

 hemp ; coarse flax ; it has a limited use in surgery.

Toxa (toks'-ah) [pi. of Toxum, from to^ik6v, poison]. 

 Diseases due to poisons. 



Toxaemia (tohs-e / -me-ah). See Toxemia. 



Toxalbumin (toks-al ' ' ' -bu-miii)\ro^iK6v, poison ; albumin, 

 white of egg]. A proteid subs'.ance resembling a ferment 

 rather than a poison. Any one of the poisonous albumi- 

 noids which are produced or separated from the albu- 

 min of the tissues by the agency of bacteria, and enter- i 

 ing the circulation, constitute the cause of the general 

 symptoms of infectious diseases. Toxalbumins have 

 been obtained from cultures of a number of bacteria — i 

 among others from those of diphtheria, typhoid I 

 cholera, tetanus, glanders, tuberculosis, anthrax, 

 pneumonia; likewise, also, from cultures of the staphy- 

 lococcus pyogenes aureus, the swine-plague bacillus; 

 from those of certain germs found by Booker in the , 

 stools of the summer diarrhea of infants, and from 

 of two toxicogenic germs isolated by Yaughan from 

 drinking-water. It is possible that poisonous albumin 

 ous substances are also produced by animal parasiti 

 organisms. Thus Viron has isolated a toxic ; 

 from the fluid of hydatid cysts. 



Toxanemia (toks - an - e'-me- alt) [to? ikov, poison; 

 priv. ; ai/ia, blood]. Anemia produced by poisons 



Toxemia (toks-e f -me-ah) [to^ik6v, poison ; aiua. blood] 

 A condition of the blood in which it contain 

 ous products, either those produced by the bod) cell 

 and not properly eliminated, or those due to the ^ 

 of microorganisms.
