Pathologic fracture occurs in a bone with preexisting stuctual weakness. The author reviewed 30 cases of pathologic fractures in which admission record and X-ray finding was well preserved among 53 cases admitted patients in the department of Orthopaedic Surgery, Seoul National Universty Hospital for 10 years from 1967. The results were as follows: 1.Age & Sex incidence showed even distribution. 2. The most frequent involved site was femur (40%) 3. The underlying etiology was as follows: 2 chronic osteomyelitis 1 homophilia 7 benign tumor 20 malignant tumor 4. metastatic tumor was the most frequent cause in 30 cases. 5. Treatment was as follows: Conservative treatment 4 cases Surgery 21 cases.

PURPOSE: We analysed the role of modified Gianturco self-expandable stents in the treatment of tracheobronchial stenosis in 13 patients. MATERIALS AND METHODS: We inserted modified Gianturco self-expandable stents under the fluoroscopic and bronchoscopic guidance. There were stenosis in the trachea(n--2), the right main bronchus(n=2), and the left main bronchus(n=9). The causes of the stenosis were endobronchial tuberculosis(n=10), intubation granuloma (n=l), restenosis after surgical reconstruction(n=2). RESULTS: Dyspnea or wheezing was improved within 1 or 2 days following the procedure. There were 32% and 22% respective increase in average FEV1 and FVC. Lung perfusion scan showed 9.6% increase of perfusion in the involved lung. No complications related to the procedure were encountered. During follow-up period of up to 31 months, 2 patients showed tracheal or bronchial restenosis, at 3 and 6 months, retrospectively. There was a distal migration of the stents in one case. CONCLUSION: During the follow up period after stent insertion, improvement of the obstructive changes and dyspnea persisted in 10 out of 13 patients. The modified Gianturco self-expandable metallic stents may be a good choice for the treatment of tracheobronchial stenosis, either as a primary treatment, or when the reconstruction failed.

PURPOSE: The purpose of this study was to determine the following:the safety of fine needle aspiration biopsy in immunocompromized children with radiographic features of Pneumocystis car/nil pneumonia, its diagnostic rate in those groups and the appropriate radiographic stage for fine needle aspiration biopsy to prove the etiologic agent. METHODS AND MATERIALS: We retrospectively reviewed the patient records of 16 children with immune compromizing diseases who had undergone fine needle aspiration biopsy of the lung. They showed the infectious sign of the lung along with the radiographic pattern of diffuse pulmonary disease, suggesting Pneumocystis carlnil pneumonia. All patients had underlying lymphoreticular malignancies including 14 acute lymphocytic leukemia and 2 non Hodgkin's lymphoma. According to the radiographic pattern of biopsy site, parenchymal disease was categorized as fine reticulonodular density(n=4), ground-glass opacity(n=9) and compact consolidation(n=3). We assessed the diagnostic rate of Pneumocystis carinii pneumonia and complications in each of the three groups. RESULTS: A diagnosis of Pneumocystis carinii pneumonia was established by fine needle aspiration biopsy in 9 patients(56%) including 2 of 4 patients with fine reticulonodular density, 4 of 9 patients with ground-glass opacity, and all 3 patients with compact consolidation. Four patients(25%) developed pneumothorax, and three of them required tube insertion. There was no patient who developed hemoptysis. CONCLUSION: Fine needle aspiration biopsy is a safe and easy method that can yield Pneumocystis carinii organism at a relatively high rate in immunocompromized children with diffuse pulmonary lesions suopicions of Pneumocystis carinii pneumonia. We recommend performing fine needle aspiration biopsy regardlesss of radiographic patterns when Pneumocystis carinii pneumonia is suggested.

Trichorrhexis nodosa(TN) denotes small node-like swelling with a loss of cuticle of the hair shaft through which the hair readily fractures. The basic cause of TN is mechanical or chemical trauma, and a contributing factor is an inherent weakness of the hair shaft. We report a case of localized TN in a 37-year-old male. He had an ovoid hair patch with multiple small white-gray dotted and stubby hairs localized to the right occipital scalp. TN is known to be the commonest of all hair shaft anomalies (Price, 1975). However TN is rarely reported, and there have been only four reports in Korean dermatological literature, to our knowledge, which might be due to underdiagnosis of this disorder. We postulated that diagnostic difficulty lies in the discrepancy between terminology and gross morphological findings.

A collodion baby is born with a tough, inelastic parchment-like membrane covering the whole body surface. As the meinbrane fissures and peels, a more characteristic ichthyosiform change is evident beneath the collodion membrane. Uncommonly, normal skin is found under it. We herein present two cases af collodion baby, which were confirmed as a sporadic case of lamellar ichthyosis and a case of lamellar exfoliation of the newborn, respectively, after long-term clinical observation. It is necessary that detailed genetical and molecular biological studies should be perforrned in order to elucidate the fur:damental, molecular changes that cause these dramatic cutaneous changes.

Hand tumor may arise as primary growth from any of the tissue present in the hand. Most are benign and malignant are uncommon. The hand is a sensitive organ, has a little potential space and moving parts, so tumors are usually detected early because of pain, impairment of function or swelling. A knowledge of frequency, location and clinical characteristics of hand tumor is invaluable in diagnosis. Usually early susgical measure is the treatment of choice. For the period of 6 years from 1962 to 1977, 29 cases of hand tumor were treated surgically and the results of clinical observation were as follows 1. Of 29 cases, benign tumor was 25 cases (86%) and bone-origin tumor was 18 cases. Enchondroma and enchondromatosis was the most frequent (12 cases). 2. The tumor occurred 22 cases in phalanx, 10 in metacarpal, and 2 in carpal bones. 3. The tumors were treated with excision in 11 cases, curettage & bone graft in 10, amputation in 4, biopsy in 2 and no treamtent in 2. 4. The most frequent site of enchondroma and enchondromatosis were ulnar side, ring and little finger, and of these metacarpophalangeal joints were involved most frequently.

Unilateral absence of a pulmonary artery is an uncommon anomaly, which presents as an isolated lesion or in combination with other congenital heart disease such as TOF or PD^. We encountered three cases of isolated unilateral absence of a pulmonary artery;one was left pulmonary artery agenesis with right sided aortic arch and the others were right pulmonary artery agenesis with left sided aortic arch. Plain chest radiograph showed considerable loss of unilateal lung volume and lack of ipsilateral hilar shadow. Pulmonary angiogram which was done in two cases, revealed proximal interruption of a pulmonary artery. Chest CT was done in only one case, on which right pulmonary artery was absent and was replaced by adipose tissue. CT with its clean demonstration pulmonary artery without any evidence of aquired obstruction of a pulmonary artery by pulmonary embolism or tumor invasion, maybe a valuable method for evaluaton of the unilateral absence of a pulmonary artery.
