ARYTENOIDERAPHY. 
Arytenoideraphy is a new surgical treatment for roaring due 
to laryngeal hemiplegia. The operation consists of suturing 
the arytenoid cartilage to the crico-thyroridean ligament and 
excision of the thyro-arytenoidean ligament (vocal cord). 
From a physiological and surgical aspect, the operation is 
much more rational than arytenectomy, and, being less com¬ 
plicated, is not followed by the same serious sequelae. 
To date six patients have received the treatment, with re¬ 
sults varying from marked improvement in two cases to com¬ 
plete recovery in four. 
A detailed description will be submitted to the profession 
when more'data is at hand. 
THE PERIOD OF IMMUNITY IN TETANUS. 
From the evidence of the following case it would seem the 
period of immunity in tetanus is very transient. 
In March, 1897, a case of acute tetanus was presented at the 
clinics. Under the usual depresso-motor treatment, the disease 
gradually aborted in five weeks. Five and one-half months 
later the disease recurred, with all its acuteness, and resulted 
in death three weeks later. 
In both instances the cause was a nail-prick in a hind foot. 
Tetanus antitoxin has entirely been discarded in the treat¬ 
ment of tetanus. Its value as a preventive is indeed doubtful. 
manorek’s antistreptococcus serum 
has thus far failed to give positive results in the treatment of 
purpura hsemorrhagica.
