ACNE 457 



which is one of the commonest locations of the disorder, due to pressure of 

 the muzzle, the accompanying figure shows a muzzle recently put on the 

 market (Fig. 1(51), which obviates the pressure on the nose, the ordinary 

 nose strap being replaced by a snooth metallic arch. The ordinary 

 muzzle can be covered b}^ ra^vhide, leather or wadding or, better still, 

 the portion toward the nose faced with patent leather. The treatment 

 consists in the energetic local application of various external preparations. 

 If the aeneous nodules are in the early part of their development, we 

 must puncture them or open the follicles by some strong antiseptic, such 

 as salicylic or balsam of peru ointment. In cases where purulent dis- 

 integration has gone on it is advisable to open the pustules. This is 

 l)est performed by means of a small bistoury or short strong needle, 

 and then fill in the opening with iodine or paint it with disinfecting 

 solutions, such as pyroktanin solution (1 to 10 of alcohol), or a 1 to 1000

 with boracic acid, or bismuth-formic-iodide. This should be used once a

Frohner advises curetting the cavities and the use of the creolin 

 ointment just mentioned, and in some cases cauterization with nitrate 

 of silver, or powdering with sulphonal and tannic acid. In cases of 

 circumscribed acne it is advisable sometimes to cut out the diseased 

 portion of the skin. 



The scales or scurf must be removed daily, until the pus is cleared 

 out and granulation has commenced, then encourage the formation of a 

 scab by using one of the various antiseptic dusting powders or the daily
