The treatment of Achilles tendon rupture is controversial between surgical repair and conservative cast treatment. This study was attempted to compare the biomechanical and morphological results between operative and nonoperative treatments of experimentally tenotomized rabbit Achilles tendon with the lapse of time. A total of 72 adult rabbits were used. After tenotomizing the Achilles tendons, the subjects were divided into 3 groups according to the time of the initiation of the treatment and each group was subdivided into 2 further subgroups according to the method of treatment; immediate operation and nonoperation, 1 week delayed operation and nonoperation, and 2 weeks delayed operation and nonoperation subgroups. Ten animals from each subgroup were sacrificed after four weeks of cast immobilization and the Achilles tendons were prepared for the gross, biomechanical and histological examinations. At the same time, two animals from each subgroup were examined by Microfil perfusion for microvascular changes in the healed tendons. On biomechanical examination, maximal loads were decreased with the lapse of time in each treatment method, and there were statistical significances between the immediate and 2 weeks delayed operation subgroups, 1 week and 2 weeks delayed operation subgroups, and immediate and 2 weeks delayed nonoperation subgroups. A maximal loads were higher in the operative treatment of each group but there was no statistical significances between operative and nonoperative treatment of each group. The results of absorption energy and stiffness were similar to those of maximal load. In conclusion, these results suggest that a rupture of the Achilles tendon should be treated as early as possible preferably within 1 week, in order to achieve a high tensile strength irrespective of the treatment method. In terms of rerupture, nonoperative treatment is comparable with surgical treatment if a rupture of Achilles tendon is managed within 2 weeks of injury.

A retrospective study was conducted on 10 patients who had undergone extended pyelolithotomy for staghorn calculi. There were some complications which were such as retained stones in 3 cases, urine leak 1 case, pneumothorax 1 case, but this surgical technique was relatively simple and easy for patients with staghorn calculi disease.

Plastic surgeons have frequently encountered wide and long skin defects which require flap coverage. These include defects that occur after radical tumor resection of the head and neck region, release of severe bum scar contracture, and defects with exposure of the bone or tendons in upper and lower extremities. Lateral thigh fasciocutaneous flap, first introduced by Baek in 1983, has a long and wide skin territory. By using this flap, we performed 6 cases of burn scar contractures and 2 cases of head and neck cancer defects. In the flap elevation, it is not necessary to change the patient's position, therefore, the two-team approach shortens the operating time. The donor site can be closed primarily if the width of flap is not over 8 cm. The donor scar of the thigh is easily concealed. The lateral thigh flap can also be used as a composite or sensate flap. We conclude that, due to the lateral thigh flap being a thin and pliale fasciocutaneous flap which has a long and wide skin territory, it is very useful for reconstruction of large skin defects.

Varioua articles have been reported that extemal contactants were the cause Acne venenata. The daily use of cosmetics are tbe cause of Acne minor in adult wamen. To distinguish this from other type of Acne venenata due to extemal contactants Kligman had coined the term Acne cosmetica, which is a low grade persistant acneiform eruption with occasional papulopustulea in adult women. The authors have tested a wide range of available cosmetics(Total twenty including four kinds of cold cream species, two of cleansing cream species, three of nutrient cream species, six of lotion species, three of foundation make up species and two of foreign cosmetics) using the rabbit ear assay recently popularized by Kligman in order to evaluate comedogenic effects of various Korean ccsmetics. The results a.re as follows. 1. Among these twenty facial cosmetics, We observed no comedogenccicy in two facial cosmetics, mildly comcdogenecity in twelve facial cosmetics, moderately comedo- genecity in four facial cosmetics and severe comedogenecity in two facial cosmetics. 2. Histologic gradings were paralleled the findings of tbe naked eye in up to 65% 3. There were significant differences on comedogenecity between Korean cosmetics and foreign cosmetics which used by Kligman. 4. There were no significant diffrences between cold cream species, cleansing cream species. nutrient, cream species, lotion species and foundation make up species. 5, There were various differences among twenty kinds of every cosmetic specie.

To a patient suffering from intractable pain due to the terminal state of cervix cancer, 7% phenol-glycerine solution was injected through the L2-L3 interspace. We obtained a good result of pain relief, but motor paralysis developed.
