cover the necessary surgical procedures so that today these can be undertaken earlier, with greater safety and effect and aTithout the risk of still further peripheral spread to give a type of lesion we met in the prepenicillin days. In these cases, penicillin is not a substitute for surgery. In the out,patient departments of hospitals where beds are filled, we see a number of patients already with x-ray evidence of osteomyelitis under so-called penicillin treatment, often in itself inadequate. Their symptoms may have improved, lulling those concerned to continue with a regime which never can cure a local condition long, since it requires drainage of well walled-off abscess or the removal of dead bone before the natural repair processes can get under way.

the Life, Due to Stimulation
of the Carotid Plexus.
G. Guntert.
Welt 4: 33, 1949.
Arrest of the function of the heart and respiration may be caused by chemical, mechanical, or irritating stimulation to the carotid plexus. The author suggests the use of anesthesia on the reflex zones of respiration and cardiac activity. With the use of an anesthetic, the likelihood of incurring trauma on the carotid plexus is diminished.
ORAL PATHOLOGY Damages Due to Overstrees of the Masticatory System Caused by Endocrine Disturbances (Lipophile, Dystrophia, Myxedema) . W. Friedrich and A. Schmitz. Deutsche zahniirztl. Welt 4: 335, 1949. Neurovegetative changes of the body are cau.sed by the lack of food, and especially the foods rich in albumin. Examples of these neurovegetative changes are hunger dystrophia and hunger osteopathy. Bone changes are manifested in the periodontium. These bone changes include a thickening of the lamina dura and an enlargement of the periodontal space. The changes are most pronounced in the area of the lower anterior teeth, the upper and lower premolar areas, and the area of the upper lateral incisors. It i,s questionable as to whether the changes in the bone may be due to, and the re$ult of, local causes.

Thyroglossal cysts and their associated sinu,ses constituted 40 per cent of the cases seen at the Lahey Clinic, presenting various tumors, cysts, and sinuses of the neck, excluding lymph node enlargements. Three hundred eighty-four patients with such cysts and sinuses were operated upon and the authors have been able to make follow-up studies on three hundred ten of these patients. A thyroglossal cyst or sinus may be found at any level in the midline of the neck from the foramen ceeum to the suprasternal notch, but the majority of them are just below the hyoid bone. The diagnosis of thyroglossal cyst i,s not dificult. The presence of a firm cystic tumor in the midline of the neck at. the level of the hyoid bone or over the thyroid cartiTransillumination is of little use as few lage is usually sufficient to make the diagnosis. cysts are tran.slucent. Elevation of the tongue will help to make the diagnosis, and this sign i.s of value in distinguishing it from a true sequestration dermoid cyst. Bronchial cysts are lateral, occur under the sternohyoid muscles, and usually develop later in life. Lipomas can be distinguished by their distinct edge and lobulation.
