The delayed blanch is one of the most discussed but undecided facets of atopic dermatitis as yet. At present, they favor the theory that delayed blanch is due to vasoconstriction, but it is not obvious whether this is due to "true" vasoconstriction or to the blood vessels being narrowed by the surrounding exudative edema, resulted from vasodilatation and increased capillary per meability. We compared cutaneous response of severe atopic dermatitis with that of age matched non-atopic individuals after intradermal injection of acetylcholine by means of naked eye and laser Doppler flowmeter examination, control group showed flare and wheals while at,opy group resulted in delayed blanch in addition to flare and whealing. The results of laser Doppler flowmeter examination revealed that, as compared to baseline, atopy group showed statistically significantly increase in spite of delayed blanch. We suggested that the delayed blanch may be not due ta va.soconstriction but due to the vasadilatation and aceumulation of edema fluid.

237 patients with Legg-Calve-Perthes disease were treated during past 12 years. Among them, a comparative study was done for 87 patients who were followed up over 2 years. They were analyzed according to Catteralls classification and divided into a group of conservative treatment and of surgical treatment. 74 patients were boys and 13 patients were girls and the ratio of boys to girls was 5.7 to 1. The mean age was about 6.9-year-old. Bilateral involvement was observed in 6 patients. According to Catterall classification. 1(1.1%) was classified as group I, 27(29.0%) as group II, and 36(38.7%) as group III, and 29(31.2%) as group IV. According to assessment by Harrison et al., satisfactory result was achieved in 63.2% of cases of conservative treatment and 34.3% of cases of operative treatment. The measurement of epiphyseal quotient and femoral head sphericity(by Mose) were considered meaningful methods for assessing the result of the treatment. The most frequent one of “Head-at-Risk” factors was lateral subluxation of femoral head. The result of treatment was not always coincided with the classification by Catterall. In bilateral involvement, the first affected hip had better prognosis than contralateral one.

The anterior cruciate ligament injury is one of the most common ligament injury of the knee joint, and anterior cruciate ligament is as important structure for stabilization as a primary restraint. Noyes reported that the diagnosis of a tek of the anterior cruciate ligament was made by the original treating physician in only 6.8%. And there are many controversies in its treatment. It is certain thatearly diagnosis and treatment are th most important clue. Authors studied 48 patients of isolated anterior cruciate ligament injury who were diagnosed by same physician from Jan. 1983 to Dec. 1985 after follow ups ranging from six mnths to 4 years, average beimng one year and two months. The results were as followings: 1. The most common cause was sports injury. 2. The most common sign and symptom were hemarthrosis in acute injury and giving way in chronic injury. 3. Anterior drawer test without anesthesia had 25% of diagnostic accuracy but pivot shift test under anesthesia 95.8%. 4. 31 cases in 48 cases (64.8) had associated meniscal injury. 5. In acute torn ACL, the primajy repair was preparable but conservative treatment with arthroscopic partial menisectomy was eful in chronic case.

Although procedures to reproduce the lost thumb through osteoplastic reconstruction and adjacent finger transfer operations appeared reasonably successful in providing for better prehension, nonetheless the methods lacked predictabiiity and too often the results were unacceptable esthetically. In recent years the development of microsurgery and surgical experiences has made it possible to free one stage transplantation of toe to replace missing thumb. Based on our past experiences with limb replantation since 1975, we accomplished the first toe to thumb transplantation done in Korea on October 28, 1978. Therafter we succeeded in one stage toe-to-thumb transplanatation in five cases. The shortest follow up period was thirteen months, and the longest, twenty-three months. One cases was excluded in this report due to short follow up period. Excellent results were achieved in all cases. There were no limping or pain while walking after removal of great toes or second toe. Great toe transplantation is more favorable donor area than second toe in toe-to-thumb transplantation. Free toe-to-thumb transplantation on making a thumb in missing thumb is the most excellent method of thumb reconstruction, but skillful technique and specialized microsurgical training is mandatory.

Sixteen microvasular free flap transfers have performed during recent two years in this department, which was first attempt in Korea. Neurovascular free flap was nine and vascular free flap was seven. The donor flaps were thirteen dorsalis pedls falps, two groin flaps and one latissimus dorsi flap respectively. The recipient sites were heel pad loss, vital organ exposure and scar contracture lesions in extremity. Their main cause of soft tissue defect was traumatic in all. All patients have experienced more than two times of split thickness skin graft before free flap transfer. The success rate of vascular free flap transfer was 94%. The only one failure case was due to venous thrombosis, but secondary split thickness skin graft performed with satisfactory result. The follow up period was from 5 months to 20 months. Sweating in transferred free flap was found at all neurovascular free flap within postoperative 4 months. Adequate 2-point discrimination was obtained at six patients of nine neurovascular free flaps and protective sensation seems to progressively improve in remained three patients. Two point discrimination was shortened at hand after neurovascular dorsalis pedis flap transfer in two cases. The weight bearing function at heel pad region and tactile sensation at hand have satisfactorily recovered after free flap transfer. Free flap transfer have many advantages compare to conventional skin graft, such as shorter therapeutic time, lesser physical and economic burdens, primary covering to vital organs and protective sensation of neurovascular free flap transfer. The most important factors are meticulous microvascular operation technique and anatomic knowledge.

It is notoriously difficult to obtain a sound bony union of congenital paeudarthrosis of tbe tibia with conventional methods. This paper is the results of using the free vascularized fibular graft for congenital pseudarthorsis of the tibia in 7 patients since 1978 in this hospital, which is the first attempt in Korea. During the follow-up periods from 9 months to 32 months, 5/7 patients(71%) had good or excellent bony union, 2 patients had bone resorption at tbe distal site of grafted bone and required a second supplementary cancellous bone graft with electrode insertion. So it is thought that the free vascularized fibular graft is one of good methods of treatment for congenital pseudarthrosis of the tibia.
