Subacute osteomyelitis of the mandible
after each meal and also chewing the betel nut. The Chinese, on the contrary, have no dental hygiene worth mentioning, and the soft rice lodges undisturbed in the interstices of the teeth. The Chinese in general are hardy and resist infection far better than the Tamils, and the latter’s superior teeth cannot. be attributed to bacterial defense any more than to vitaminiferous diet. There is abundant evidence that the coolies of the tropics have abundant exposure to ultraviolet rays and much of their food shares this advantage.

The authors incidentally report 8 cases of this sequence and then comment as follows: The discovery of the Vincent bacilli and spirochetes in painful sockets is doubt,less without significance, although it is a remarkable coincidence that all of the patients in the series presented this find when pain was present, and that the organisms vanished with the pain. The authors sought to disinfect the mouths of patients before ext,raction by the use of sodium perborate, which does not destroy but exerts a bactcriostatic action on microorganisms. In 400 cases this precautionary measure was used, but postextraction pain was present to some extent iii 5 per cent. IInfortunately they neglect to mention the normal proportion of these cases in unselected material for comparison, a.lthough it must be more t,han 5 per cent for the authors think it worth while to recommend the use of the sodium perborate as a routine practice before extraction. Other causal elements may be present, for the solution of perborate being injected warm into the socket after extraction as a secondary measure involves keeping the socket open, and the authors have not.iced that in painful sockets there is mostly an occlusion of the opening. Moreover, if pain is present, relief is immediate. Hence in any case after extraction the socket must be kept open. In rare cases there may, of course, be a special reason for pain, such as fracture of the process.

The authors give, three case histories with the following summary: These ca,ses show the likelihood of the existence of a special type of osteomyelitis with the following characters. On the anatomic side,there is a granulomatous reaction of the connective tissue of the int.raosseous tissue with a certain amount of osteolysis. Such lesions are seen at a maximum in the spongy tissue of the bone, and the horizontal ramus infected by some microorganism forms a trough of compact tissue with concavity above, which is filled with exuberant granulations more or less purulent and bleeding. The process may extend to the entire horizontal ramus and involve the central portion of the ascending
emus. OH the clinical side there is no violent OIW~, and for some clays oh,: degree of pain is in sharp contrast with the absence of objective symptoms. Finally there are tumefaction, loosenin, 0’ of teeth and the formation of multiple fist,ulas. From the operative side prompt intel,vcntion will limit the process, this consisting of a curettage of the cavity. In this form of osteomyelitis there is evidently no possibility of sequestrum formation. The latter we may expect in the acute type of osteomyelitis, but in this subacute form we see, instead, proliferation in the connective tissue and rarefaction of bone. The ;adiodiagnosis of this condition is chiefly negative at first and hence of no va,lne for early recognition. There may be transitions between the acute and xnbacutc forms, for small sequestr-a may be found in the contents of the cavity. Nut&ion

It has been generally accepted by ph~siolopists and by psychologists that emotions such as anger, fear, pain; horror and repulsion, as well as anxiety, tiespondencp a,nd despair cause an inhibition of excretion and mobility, and this I*eaction occurs while the object arousing the emotion is still in eonsciousnew. The author states that these emotions by liberating an excess of epinephpin into the blood stream, or by acting on the sympathetic ga.nglions liberate sugar from the liver cells into the blood stream to such an extent as to cause transient glycosuria. However, from his study on 300 women patients with psychosis the author believes that chronic emotionalism and morbid moods through their protract,ion and summation have less and less effect on visceral functions but work their greatest harm at the higher levels.

Working in Darien General IIospital, Darien, South Manchuria, the author endeavors to ascertain the probable effects on the growth of newborn rabbits of a medium quantity of x-ray applied to their bodies. His conclusions show that the x-ray obstructs the growth in 64 per cent of these rabbits. The thyroid is slightly damaged by x-ray radiation.

Sherman believes that one quart of milk a day is needed in addition to other foods if children between the ages of three and thirteen years are to fulfill their calcium requirement. of one gram daily. No other food, vegetables for example, seems satisfactory as a substitute for the supply of available calcium for the body. If the child will not take milk as such, the author suggests that it be used in the preparation of the child’s other foods.
