BACKGROUND: To evaluate the usefulness of exercise echocardiography in diagnosis of coronary artery disease and to compare it with exercise ECG test. METHOD: We performed exercise test in 48 patients who suffered from angina-like chest pain, according to the modified Bruce protocol. During exercise, we observed the ECG changes and recored the images of left ventricular wall motion before and after exercise on the video tape. The echocardiogram were digitally stored and displayed in a format that allowed simultaneous analysis of rest and stress images. Newly developed left ventricular wall motion abnormalities were determined as positive findings. RESULTS: The feasibility of exercise echocardiography was 75%. The sensitivity and specificity fo exercise ECG test was 67% and 89%. The sensitivity and specificity of exercise echocardiography was 85% and 100%. The sensitivity of ECG and echocardiography was 50%(7 of 14) and 78.6%(11 of 14) in those with one-vessle disease and 84.6%(11 of 13) and 92.3%(12 fo 13) in those with multi-vessle disease. CONCLUSION: Exercise stress echocardiography was very usefull method for detecting the coronary artery disease especially in single vessle disease. And it had much higher accuracy than the stress ECG test.

The rupture of anterior cruciate ligament has been diagnosed by stress test, radiogram and diagnostic arthroscopy, but these methods have several disadvantages of lack of objectivity, exposure to radiation and risk of anesthesia. To eliminate these difficulties, the K-T 1,000 knee ligament arthrometer was used for the objective diagnosis in the injury of anterior cruciate ligament. We performed instrumented measurement of anterior-posterior laxity of the knee in 100 normal subjects by using the K-T 1,000 knee ligament arthrometer under the 15 lb., 20 lb. and maximum anterior pulls, and 20 lb. posterior push. The following results were obtained: 1. The mean anterior displacement at 20 lb.: 4.43mm The mean posterior displacement at 20 lb.: 2.30mm 2. The mean right knee-left knee difference in anterior displacement: 0.89mm 3. The mean anterior compliance index: 1.16mm So, we believed that a right knee-left knee difference and a anterior compliance index are sensitive measures of the integrity of the anterior cruclate ligament. And this test method was helpful for the diagnosis and objective recording in the injury of anterior cruciate ligament. This test method has following advantages: 1. There is no anesthesia risk. 2. The patient and examiner undergo no radiation exposure. 3. Diagnostic arthroscopy may be avoided. 4. Due to patient comfort, there is minimal muscle guarding.

BACKGROUND: Dermatophytosis is sometimes difficult to diagnose deinitively if it has atypical clinical characteristics and mycological tests are negative. Histopathologic findings may be different depending upon the location and causative dermatophytes. OBJECTIVE: The purpose of the present study was to evaluate histopathologic characteristics nf dermatophytosis depending upon the areas of involvement. METHODS: We evaluated the clinical and histopathologic features of 32 cases of dermatophytosis which were diagnosed by skin biopsies at the Dermatology Department of branch hospitals of Catholic University Medical College from March 1985 to August, 1994. Histopathologic features were observed in three dilferent groups divided by location, area of terminal hair, areas of vellus hair and hairless areas. RESULTS: Epidermal changes including hyperkeratosis, parakeratos, acanthosis, spongiosis and neutrophilic exocytosis were frecuently observed in the three groups of Iermatophytosis. In 7 cases of tinea capitis and linea barbae, follicular and inflamma or changes of the deep dermis were important. Hyphae and spores were observed in 71%(5 cases) and 57%(4 cases) respectively, in the follicles. In 19 cases of tinea faciale, tiriea corporis and tinea cruris, change epidermis and superficial dermis as well as findings of follicular infundibulum were important. Herphae were observed in 84%(16 cases) and 53%(10 cases) in the stratum corneum and vellus hir follicle respectively, and in 3 cases the hyphae were observed only in the vellus hair follicle. Sandwich sign, known to be important clue of dermaliophytosis, was observed in only 5%(1 cacse, In 6 cases of tinea manus and linea pedis, hyphae and spores were rebserved in 100% (6 cases) and 33%(2 cases) respectively, in the stratum corneum. CONCLUSION: We consider tha histopathologic observations may of great help to diagnose some difficult cases of dermatophytosis and the presence of hyphae n .he vellus hair follicle may be a more frequent and important finding than the sandwich sign the dermatophytosis of the vellus hairy regions.

Three cases of congenital coxa vara were treated by subtroch-anterie abduction osteotomy with percutaneous pin fixation of both fragments. The indications of the corrective subtrochanteric osteotomy for coxa vara deformity were the neck-shaft angle of 100 degress or less, the presence of marked gluteus medius limp and the vertical neck defect with progression of the varus deformity. Through a lateral approach, the lateral aspect of the proximal end to the femoral shaft was exposed and 2 Steinmann pins were inserted through the upper and lower levels to the proposed osteotomy. The distal pin was inserted perpendicular to the long axis of the femur and the proximal pin at an algle of desired correction to the distal pin and a subtrochanteric transverse osteotomy was completed. Two Steinmann pins were paralell to each other by adducting the proximal fragment and abducting the distal fragment. and the lateral cortex of the proximal fragment was impacted into the marrow cavity of the distal fragment. The Steinmann pins were then incorporated in the hip spica cast. The object of the operation was to correct the coxa vara, to change the stress on the vertical fissure in the neck from shear to compression and to overcome shortening of leg. With this technically simple method, the authors achieved adequate correction of the deformity. The ostetomies healed rapidly and the medullary canal was re-established in all cases, The gait of each patient was markedly improved and the Trendelenburg test become negative in all of them. One of these patients showed a mild recurrence of varus deformity and limp 2 years following surgery.

Allergic contact dermatitis from aroma oils has long been recognized and with increasing frequency. Contact dermatitis of the allergic type of fragrances used for aromatherapy has been reported rarely, and only in patients exposed due to their occupation. We report herein a case of allergic contact dermatitis to aroma oils in an aroma therapist. A 25-year-old woman, an aroma therapist, had been treated with topical steroids under the impression of contact dermatitis. She had had pruritic erythematous maculopapules on the arms extending to the hands for the previous 6 months. Patch tests showed strong reactions to aroma oils(3% fennel and 3% juniper). The skin lesions were cleared after she stopped her job. However, re-exposure to aroma oils caused eczematous lesions repeatedly at the sites previously involved. We predict that increasing popularity of aromatherapy will lead to increasing number of patients developing allergic contact dermatitis from aroma oils. This has to be taken into consideration when testing patients with suspected contact dermatitis.

Freys syndrome is characterized by attacks of facial erythema and gustatory sweating occurring in the cutaneous distribution of the auriculotemporal nerve. After sugery, trauma, abscess, or other diseases of the parotid gland, the postganglionic sympathetic and parasympathetic nerve fibers are disrupted. Some misdirected auriculotemporal nerve fibrils join with the distal sympathetic nerves innervating the sweat glands and subcutaneous vessels. We report a case of Freys sindrome in a 6-year old boy without any definite injury to the parotid gland. After considering our case and review of literature of Freys syndrome in children, we conclude that there may be a congenital defect in the auriculotemporal nerve innervation responsible for cases occuring in children.

Hematogenous contact dermatitis may be produced by the systemic administrationof a drug to an individeal who has been previously sensitized by the topical application of the drug or related chemicals. 37 year-old male patient had frequent rhus dermatitis. He took rhus with chicken for treatment of peptic ulcer, on next day generalized skin rashes with itching sensation were developed. the aptient was diagnosed as hematogenous contact dermatitis or systemic exzematous contact dermatitis according to the history, symptoms and the result of patch test.
