A clinical and histopsthological study were done on 1,817 biopsied inflammatory skin diseases among 58,386 out-patients in Dermatologic department of Korea University Hospital during the period of 24 years from January, 1962 to December, 1985. The results were summarized as follows : 1. According to pattern analysis(Ackerman AB), 1,605 cases(88.3%) of inflammatory skin diseases were classified into 9 patterns and by author's modified pattern analysis, additional 437 cases could be classified. 2. Of the 1605 cases which were classified by 9 pattern analysis, 1185 cases(78.8%) of inflammatory skin diseases were diagnosed as individual disease entity. The ratio of accordance between the histopathological diagnosis and clinical diagnosis on the biopsied inflammatory skin diseases was 44.5%, 3. The ratio of accordance between the histopathological diagnosis and clinical diagnosis by the patterns were '. Vasculitis(75.5%), Subepidermal vesicular dermatitis (73.3%), Nodular and diffuse dermatitis(68.2%), etc. 4. The diseases showing above the 70% accordance were scleroderma, erythema induratum, vitiligo, arthropod reaction, etc; and the diseases showing under the 30% accnrdance were erythema multiforme, erythema annulare centrifugum, neurodermatitis, etc.

Fifty-seven patients with Tinea versicolor were studied clinically and mycologically, from May 1980 to August 1981, at the Department of Dermatology, Korea University Hospital. Also observed were twenty-four Tinea versicolor patients, who were factory workers frorn Wolsan area, and whose diagnoses were confirmed by clinical and mycological examination. The results obtained were as follows: 1. During the study period, out of a total of 5475 out patients, there were 57 cases of Tinea versicolor for an average of 1.04 percent. In Wolsan area, out of a total of 1835, there were 24 cases of Tinea versicolor(1.3%). 2. The average age of all patients at visit was 27.9 years, the oldest patient was 69 year-old and the youngest patient was 13 year-old. The onset of disease was observed most commonly in June, July and August, these patients comprising 55.6 percent of the whole series, 3. The male to female ratio was 7:1, excluding workers from Wolsan area. 4. Distribution of lesions were anterior chest(21.4%), back(18.0%), alxlomen (17%), axilla(16.5%), neck(12.6%), pubic area(4.4%), upper extremites (4.4%), hip(3.4%), and lower extremites(2.4%). The incidence of hyperpigmented lesions was 71.8% and of hypopigmented lesions was 28.2%.

Orthopaedic Surgeons have recognized for a long time the importance of end-result studies of low back pain, and the analyses of such reports abound in orthopaedic journal. Most studies were designed to answer definite questions relative to the results of a specific treatment. It is unfamiliar for us to use rating systems developed by the Occidental in the analyses of treatment of low back pain. There has not been generally accepted rating systems for the treatment of low back pain in Korea. Therefore a new rating system for the results of treatment of low back pain is proposed.

There are many hypotheses of spinal instability after trauma and the concept had been recently changed from 2-column concept by Holdsworth to 3-column concept by Francis Denis & McAfee and also there are controversies about the operative management of the unstable thoracolumbar spine fractures and fracture-dislocations. So we tried to find some relationship between the spinal instability and the effect of the stabilization operation for the fractures and fracture-dislocations in the thoracolumbar spine in this study. Totally 53 cases that stabilization operation had been performed for the unstable fractures and fracture-dislocations of the thoracolumbar spine at Yonsei University Hospital, including Yongdong hospital, from March, 1973 to October, 1984 and followed up over 6 months, were reviewed. 1. Majority of the patients (84.9%) was in an active age group (20–49 years of his age) and more common in males. 2. The first lumbar vertebra was most commonly involved segment (43.3%) and falling from a height was the most common cause of injuries (50.9%). 3. Injuries to the anterior, middle and posterior column of the spine (58.5%) was the most common mechanism of injury according to the classification by Francis Denis and McAfee. 4. The wedged deformity of the involved segment over 50% was usual (71.7%) and mean wedged deformity was 57% of the height of the vertebral body and most commonly associated fractures besides the body itself was laminae fractures (46.5%). 5. Seventy eight percent of the angular deformity was corrected after Luque rod instrumentation and 76%, after Harrington rod instrumentation, 68%, after posterior wiring, 58%, after anterior decompression and anterior interbody fusion. 6. Forty twa point seven percent of the displacement in anteroposterior plain X-ray film and 58.8% in the lateral film were corrected by Luque rod instrumentation and 39.5% in anteroposterior film and 44.3% in the lateral film were corrected by Harrington rod instrumentation. 7. No significant differences in the recovery of the neurologic signs were found according to the method of surgical treatments. 8. So Luque rod or Harrington rod instrumentation is now recommended for obtaining the spinal stability as a method of surgical treatment in the unstable thoracolumbar spine fractures and fracture-dislocations.

Suppurative arthritis of the knee is a well known complication following intra-articular injection of steroids on the other hand, tuberculous arthritis following such injection is rare. From January, 1981 to April, 1986, 46 patients of tuberculous arthritis of the knee were admitted to Severance Hospital and Yong-Dong Severance Hospital of Yonsei University College of Medicine. Among them 22 patient (48%) had a history of intra-articular injection of steroids and we analyzed them. The results were as follows: 1. The average age was 48.6 years (3–71 years). And sex ratio was in 1:2.7 as female predominant. 2. Initial diagnosis before the steroid injection were osteoarthritis (13 patients), rheumatoid arthritis (6 patients), and traumatic arthritis (3 patients). The fifty percent of the patients were injected by the local practitioner and fourty five percent had a history of accupuncture and moxa cautery. The preoperative diagnosis (diagnosis on admission) were tuberculous arthritis (12 patients), pyogenic arthritis (5 patients), rheumatoid arthritis (3 patients) and osteoarthritis(2 patients). 3. The number of intra-articular injection ranged from 2 to 100 times (average 12.8) during periods ranging from 1 month to 4 years (average 19.2 months). And interval between last injection and confirmation of tuberculous arthritis ranged from 1 week to 2 years (average 7.0 months). 4. Eight patients (36%) had a active or inactive pulmonary tuberculosis. 5. The positive cultures of typical Mycobacteria tuberculosis were obtained from 11 patients 59%). 6. The modalities of treatment were synovectomy or curettage in 16 patients and arthrodesis in 6 patients. And all patients were treated by antibuberculous chemotherapy. In conclusion, we observed that tuberculous arthritis developed not infrequently after intra-articular injection of steroids. And we considered the causes of tuberculous arthritis following intra-articular injection of steroids were; 1) reactivation of dormant injection or hematogenous, spreed due to interferance of host defence mechanisms, 2) contamination by the instrument and equipment, 3) aggravation of preexisting tuberculous lesions. Whenever one try to inject the steroid into joint, bacterial culture foi the pyogenic organism including tuberculosis and fluid analysis from the joint fluid should be done before the injection. We recommend that other method for the confirmation for the tuberculosis is needle biopsy of the synovium. If the symptoms are not improved after injection or the joint shows inflammatory reaction, one must discontinue the injection and reexamine the joint fluid analysis and culture for the confirmation of the infection.

Spinal dimensions (anterior, mid, and posterior height of the vertebral body) and shape variation (wedge compression, biconcave, and crush ratio) were obtained from plain radiographs of healthy Korean men and women. The purpose of this study was to define vertebral fracture from normal spinal morphometry of Korean men and women and to compare spinal dimension between men and women. Healthy 100 men and 100 women were included in this study. Plain lateral radiographs of thoracic and lumbar vertebrae were taken with standard method. Quantitative morphometry (anterior, mid, and posterior height of the vertebral body) was performed with plain radiographs. Spinal shape variations (wedge compression, biconcave, and crush ratio) were calculated from morphometric data. Spinal dimensions and shape variation of Korean men and women were presented, and morphometric cut-off vaiues for vertebral fracture were evaluated(mean-3xSD). Spinal dimensions of men were greater than women in all level (p<0.01). Wedge compression ratios (T6, 7, 8, 9, 12, L5 level) and biconcave ratios (T12, Ll, 4, 5 level) and crush ratios (Tll, L4, L5 level) were different between men and women (p<0.01). Spinal dimensions and shape variation from quantitative morphometry can be used in objective definition of vertebral fracture which can be used in medicolegal problem, workers compensation and medical insurance.

Subcorneal pustular dermatosis is a chronic, benign, relapsing pustular eruptions characterized histologically by subcorneal pustules which contain abundant neutrophils. We report a case of subcorneal pustular dermatosis occured in a 71-year-old male with typical climcal lesions. Biopsy of a pustule showed a subcorneal cavity with numerous neutrophils, which were also scattered throughout the Malpighian layer below. The result of imrnunofluorescent studies was negative. His eruption is controlled by DDS (25-100mg daily) but the eruptions recur quickly on sessation of the drug.
