Ingrown toenails are one of the most common pathologic conditions encountered in podiatric medical practice. Many methods of treatment for ingrown toenails have been used and studied, including chemical matrixectomies, surgical approaches, and CO2 laser ablation. This study is a retrospective review of a new technique that consists of resection of the involved nail matrix using a No. 15 blade and controlled cauterization using a CO2 laser. The technique was performed on 381 painful ingrown toenails, and all of the patients were followed up postoperatively for an average of 34 months. The results showed minimal pain, a low recurrence rate, rapid return to activity, and good cosmesis. (J Am Podiatr Med Assoc 95(2): 175–179, 2005)

A new technique has been developed for the purpose of studying, by means of vapor pressure changes, the effect of wood and cellulose on the system calcium-oxide–sulphur-dioxide–water. Preliminary experiments are described. A sample calculation has been made, to indicate that vapor pressure changes might be used to determine the relative rate of consumption of sulphur dioxide and calcium oxide during the cooking of wood. Cellulose does not yield carbon dioxide in appreciable quantities during cooking.

Density Of Water

The partial molal volumes of nitrogen, oxygen, and carbon dioxide in water at 0 �C have been determined by a new technique based on the use of a Gilfillan-Polanyi micro-pyknometer as a float. The value obtained for nitrogen is 37.0 ml and that for oxygen, 31 ml. The value for carbon dioxide is found to vary from 44 to 28 ml as the pressure at which the water is saturated with the carbon dioxide varies from 0 to 6 cm Hg. The changes in the density of water at 0 �C produced by saturation with nitrogen, oxygen, and air at 1 atm pressure are -9.3, + 1.8, and -4.7 p.p.m. respectively. The density of air-saturated water is considerably greater than would be expected from the sum of the effects due to nitrogen and oxygen separately.

A new technique using the carbon dioxide (CO2) laser for the treatment of aural hematomas is described. The laser is used to make an incision into the hematoma to allow for evacuation of the blood, and then multiple, small incisions are made over the surface of the hematoma to stimulate adhesions between the tissue layers. The CO2 laser was used in this fashion to treat 10 aural hematomas in eight dogs. Follow-up ranged from 1 to 23 months. Owners evaluated the cosmetic results following CO2 laser surgery as excellent in three ears, good in five ears, and fair in two ears. Hematomas were resolved in all 10 cases, although two cases developed serosanguineous fluid accumulation that required percutaneous drainage in one case and a second laser procedure in the other case.

Laser Effect

While much is known regarding the effect of lasers on the retina, little study has been done on the effect of lasers on cornea, because of the limitation of the size of the material. Using a combination of electron microscope and several newly developed cytochemical methods, the effect of laser can now be studied on eye for the purpose of correlating functional and morphological damage. The present paper illustrates such study with CO2 laser on Rhesus monkey.
