1. The occlusion of the frontal sinus cavity with such materials as fat or others is descriptionbed. 2. The osteo-periosteal flap technique is used in this operation, with an improvement over other similar practices. 3. The treatment of the other sinus through the intersinal septum can be done without any difficulty. 4. In cases of fracture or fissure of the cribriform plate (ethmoidal fissure or fracture) with cranial hydrorrhea, we are of opinion that this operation offers the simplest means of approach for surgical treatment to this area and it is easier and less dangerous than the intracranial route used by neuro-surgeons.
A case of neuroblastoma in a child aged 10 years is reported. This appears to have been a predominantly Hutchinson type of neuroblastoma with massive skull secondaries and diffuse involvement of other bones. The characteristic features are discussed briefly.
Terramycin used alone is a most effective agent in the treatment of acute dysenteric amoebiasis. As relapses occur, amoebacides should be used as well. Most cases of amoebic dysentery may now safely be treated without hospitalization. Non-dysenteric amoebiasis does not warrant the use of expensive antibiotics.
Thirty-six consecutive batches of antitoxin have been investigated for the presence of blood group substances. In- every case an A or A-like substance was present; B substance was not demonstrable.As the injection of group substances results in the formation of immune agglutinins and haemolysins, the above findings explain the mechanism by which the injection of antitoxic sera may produce a similar result. Blood donors, especially of group 0 but also of group B may, after such an injection, be rendered dangerous by the formation of immune anti-A. Every donor should be questioned on this point and a recent history of an injection of antitoxin or of vaccine should debar the use of such a donor for recipients of other groups. The blood of every donor to be used for recipients of other groups should be investigated for the presence of immune forms of agglutinins by the relatively simple techniques now available.
