Urticaria is a common disease and a well known reaction pattern of the skin eharacterized by erythema or wheals and edema, that is the results of a local leakage ef plasma, from minute vessels into the connective tissue of the dermis. Seven hundred and sixty cases of urticaria visited to this department from January 1973 to December 1974 were studied clinically in various ways. Patients were classified as acute and chronic urticaria-acute form when the hives have been present for less than 8 weeks and chronic form when the hives lasted longer. In all patients, a detailed history, a complete physical examination, a total and differential leukocyte count, erythrocyte sedimentation rate and routine stool examination were performed. Foods were incriminated as the exciting causes of urticaria by history, diet elimination test and ingestion test. An ice cube test was done for corroboration of cold allergy. Cholinergic urticaria, was diagnosed by the appearance of small wheals surrounded by erythema after exercise, emotional disturbances or hot drinks. The diagnosis of urticaria due to drug was based on the history of urticaria following the taking of a certain drug. Infection as the inciting cause was determined by history and physical examination. The results: 1. The incidence of urticaria is 4. 6% to total number of dermatologic patients. 2. Among the 760 urticaria patients, acute cases were 498 which were 2 times more than chronic cases, and female patients were 474 cases that revealed marked high incidences than male patients. 3. The age of the patients ranged from 2 months to 87 years, and the patients between 20 and 39 years occupied more than half of the all patients. 4. Abnormal hematologic findings were more marked in acute form; leukocytosis and neutrophilia were dominate in acute form, and lymphocytosis and eosinophilia were more marked in chronic form. 5. Among the etiologic factors, the bacterial infection was the most frequent which occupied 22. 4% of the all urticaria patients. 6. Seven cases of urticaria due to parasites were clonorchis sinensis, in which I had experienced the complete recovery with the treatment of subcutaneous injection of clonorchis sinensis antigen (1: 10,000) 0.01- 0.1ml at the interval of one week. 7. In this study, the inciting or perpetuating causes could not be found in 50.8% of patients-46.2% of acute form and 59.5% of chronic form.

PURPOSE: To evaluate the treatment results of geriatric intertrochanteric fractures by using Asian-Pacific Gamma nails. MATERIALS AND METHODS: From June 1994 to June 1997, 58 cases of the intertrochanteric fractures were treated with Asian-Pacific Gamma nail, particularly compression hip screw fixation complications such as communited fracture involving lesser trochanter, transverse or reverse oblique intertrochanteric fracture. We evaluated the bone union time, neck-shaft angle, lag screw sliding by follow up radiographs, and studied complications and intraoperative cautions. RESULTS: The average age was 74.4 years old, the mean duration of follow-up was 17 months, the mean duration of bone union was 14.2 weeks, the average neck-shaft angle was postop. 133+/-2.78 degree and last follow-up was 129.5+/-3.37 degree, and the average lag screw sliding was 4.7+/-3.16 mm. Intraoperative complications were difficulty in distal drilling (posterior drilling) in 4 cases, fracture displacement by nail insertion in 3 cases, and postoperative complications were coxa vara in 13 cases, superior cutting out of lag screw with nonunion in 1 case and superficial infection in 1 case. The entry portal must be formed by awling. The fracture displacement when inserting nail could be prevented by proper reaming after inserting the C-shaped guide pin, and posterior drilling could be avoided by confirming the locking between target device and nail. CONCLUSIONS: We conclude that the Asian-Pacific Gamma nail could appropriately treat the osteoporotic, communited intertrochanteric fracture in elderly patients and we obtained satisfactory results.

PURPOSE: To evaluate the effect of common three photon energies (6-MV, 10-MV, and 15-MV) on intensity-modulated radiation therapy (IMRT) plans to treat prostate cancer patients. MATERIALS AND METHODS: Twenty patients with prostate cancer treated locally to 81.0 Gy were retrospectively studied. 6-MV, 10-MV, and 15-MV IMRT plans for each patient were generated using suitable planning objectives, dose constraints, and 8-field setting. The plans were analyzed in terms of dose-volume histogram for the target coverage, dose conformity, organs at risk (OAR) sparing, and normal tissue integral dose. RESULTS: Regardless of the energies chosen at the plans, the target coverage, conformity, and homogeneity of the plans were similar. However, there was a significant dose increase in rectal wall and femoral heads for 6-MV compared to those for 10-MV and 15-MV. The V20 Gy of rectal wall with 6-MV, 10-MV, and 15-MV were 95.6%, 88.4%, and 89.4% while the mean dose to femoral heads were 31.7, 25.9, and 26.3 Gy, respectively. Integral doses to the normal tissues in higher energy (10-MV and 15-MV) plans were reduced by about 7%. Overall, integral doses in mid and low dose regions in 6-MV plans were increased by up to 13%. CONCLUSION: In this study, 10-MV prostate IMRT plans showed better OAR sparing and less integral doses than the 6-MV. The biological and clinical significance of this finding remains to be determined afterward, considering neutron dose contribution.

The time course of recovery in vestibular neuritis varies between individuals. The aim of this study was to identify the predictors for the early or late recovery of vestibular neuritis. The inclusion criteria were patients 1) who had an acute onset of vertigo lasting at least 24 hours, 2) with a horizontal-torsional unidirectional spontaneous nystagmus, and 3) with a canal paresis of 20% or more on the bithermal caloric tests. The primary endpoint for this study was an early or late recovery of vestibular neuritis as a dependent variable. A functional level scale was used to define the late recovery (5 or more points) at seven days after the symptom onset. The secondary endpoint was the duration of hospitalization. One hundred twenty eight patients met the inclusion criteria for this study, and among them, 71 patients had an early recovery. Multiple logistic regression analysis showed that diabetes mellitus was the only independent significant variable for the prediction of a late recovery of vestibular neuritis. In addition, the diabetes mellitus was a predicting variable for long duration of hospitalization. Diabetes mellitus was a predictor for a late recovery of vestibular neuritis.

Leg length discrepancy in the growing children was developed by multiple causes; such as congenital, infection, traumatic, and mechanical facotrs etc. The discrepancy have been treated by several methods including bony lengthening which is preferable method, but epiphysiodesis also has been one of the valuable methods in which was applied to the treatment of mild to moderate leg length discrepancy in the growing children. We report on patients(15 cases) with leg length discrepancy treated by percutaneous epiphysiodesis since July 1986. There were 8 males and 7 females and the average age of them was 12.6 years old. And we also performed an experimental study which was to find out the effectiveness of the pereutaneous physeal destruction comparing the techningues between curette and drill in the bony models. The causes of leg length discrepancy were trauma in 8 cases and osteomyelitis in 2 cases, congenital dislocation of the hip in 2 cases, poliomyelitis, Legg-Galve-Perthes disease, congenital hemihypertropy in each 1 case. The average preoperative leg length discrepancy was 2.6cm(range:1.9-3.7cm), and average anticipated discrepancy without operation have been 3.7cm(range:2.2-6.3cm) at maturity. The final discrepancy was 0.9cm after 43 months follow-up. According to the result by experimental study, percutaneous epiphysiodesis with curette technique would be more effective and safe than drill thchnique. Percutaneous epiphysiodesis might be one of the useful methods for the treatment of mild to moderate degree of leg length discrepancy in the growing children, and also could be applied combining with bony lengthening for treatment of severe degree of leg length discrepancy.

The herniation of intervertebral disc is possibly diagnosed through the myelography, electromyography, discography or computerized tomography. Among them, the myelography is regarded as the popularized method that helps accurate analysis on the location and pattern of the lesion. The authors have studied 363 cases of herniated intervertebral disc with respect to the diagnostic accuracy of myelographic examination from January, 1982 to December, 1985 at the Department of Orthopedic Surgery and Radiology, National Police Hospital. The results were as follows; 1. The most common age group was 21 to 30 years old and ratio of male and female was 9.7: l. 2. The most common site of the lesion was between L4 and L5 vertebra in myelography. 3. Of the 363 cases which underwent the myelography, 305(84.0%) represented positive findings. 4. Myelographic accuracy was coincided with the clinical diagnosis regarding the location of herniation of intervertebebral disc in 262 cases(72.1%).
