Myositis ossificans is a rare benign ossifying lesion in skeletal muscles which is commonly seen after trauma. However, it has been reported that myositis ossificans can be developed without any history of trauma and surgery. A 37-year-old female presented with a painful progressive swelling in her right femoral area, with no history of trauma or other diseases, which had been developed for 2 weeks. Initial X-rays were normal. An incision biospy specimen showed a lesion of fibroblastic tissue in which areas of osteoid and trabecular bone tissue, which was compatible with the early stage of myositis ossificans. The mass was excised totally and no signs of recurrence have been noted until now.

BACKGROUND: Korea is an endemic area of viral hepatitis B with a rate of 5~10% carrier state. Therefore, hepatitis B vaccination is performed nationwide. But 5~15% of healthy individuals fail to respond adequately to the vaccine and an approved guideline for the nonresponders has not been developed yet. This study is designed to identify risk factors for those who lack anti-HBs after hepatitis B vaccination and to document the results of a double-dose revaccination in such nonresponders to the primary vaccination. METHODS: From Feb. 1996 to Aug, 1997, we assessed 51 healthy subjects(HBs Ag negative, anti-HBs negative, anti-HBc negative and a normal LFT). All subjects were vaccinated with Hepavax- B, 1.0ml, 24 by a rapid schedule(0, 1, and 2 months) and 27 by a standard schedule(0, 1, and 6 months). Anti-HBs titers were evaluated 3 months after the third vaccine and assessed the nonre-sponders (anti-HBs titer<2mIu/ml) and the hyporesponders(2~10mK/ml). All 13 nonresponders were revaccinated with 2ml of Hepavax-B 3 months after the primary vaccination. Anti-HBs titers were evaluated 1 month later. RESULTS: The differences in age(p<0.01) and smoking amount(p<0.05) between the responders and the hypo and the nonresponders were statistically significant. There were more males and higher body mass index in the hypo and the nonresponders but not statistically significant. The seroconversion rate after the double-dose vaccination was 92.3%(12/13) with an average titer of 5K08mlU/ ml(1-132.4mIU/ml). CONCLUSIONS: Increase in age and smoking amount were the risk factors of the nonresponders after the primary vaccination. Most of the hypo and the nonresponders to the primary vaccination responded adequately to the double-dose revaccination.

PURPOSE: To obtain the findings of normal variant types of lower cervical body configuration for the purpose of differention from compression fracture. MATERIALS AND METHODS: We retrospectively analysed simple true lateral radiographs of cervical spine from C3 to C7 in 157 pediatric patients who did not have definitive clinical symptoms of cervical spinal injury. We classified the variations of normal cervical spine into 5 types by their configuration. In case of rounded upper corner or anteriorly wedged type, we measured the height and the width of vertebral body to classify these types, and undertook ANOVA test and multiple range test to determine the correlation between the gross configuration and the measured values. RESULTS: Type 1 was similarly observed at each of C3 to C7 in age of 1-4 group but the frequency was markedly decreased in age of 5-8 group. Type 2a was frequently observed at both age groups, and its incidence increased considerally at C3 and C4 with advancing age. Type 2b was more frequently observed at C3 body and Type 3 was observed only at C3 body in age group 1-4. Type 4 was markedly increased at 5-8 age group. Type 2b and 3 were seen mostly at C3, but sometimes at C4 body. Height of body was statistically more significant than width of body in classification of type 2a, 2b and 3. CONCLUSION: The configuration of lower cervical spine in infants and children changes from immature oval type(type 1) to mature rectagular type(type 4) with increasing age. Among the 4 types, the rounded upper corner type or anterior wedging type of lower cervical spine should be differentiated from compresson fracture. We concluded that the height of cervical body is more significant than the width of body in simple radiographic classification of types 2a, 2b and 3.

Hydroxychloroquine, an 4-amino-quinoline, has been used widely for the treatment of lupus erythematosus due to its anti-inflammatory and immuno-modulatory activities, as well as for the treatment of malaria. A 37-year-old woman who was suspected as lupus erythematosus and treated with hydroxychloroquine for 3 weeks was seen with exfoliated annular patches and pustules on the trunk, neck, and extremities. Histological examination showed subcorneal and spongiform neutrophilic pustules with perivascular lymphocytes, eosinophils and neutrophils infiltrations. The patient had been treated with systemic steroid and antihistamine. The pustular lesions had improved 2 weeks later without recurrence. The causative drug was confirmed by a positive patch test.

PURPOSE: We evaluared the risk factors, clinical characteristic, diagnosis and treatment of neonatal systemic fungal infection in 28 cases in order to find ways to prevent development of and to improve the prognosis of neonatal systemic fungal infection METHODS: From November 1994 to August 1996, 28 premature infants who were diagnosed as systemic fungal infection at Ilsin Christian Hospital NICU were analyzed retrospectively. RESULTS: 1) The mean gestational age was 30.7 weeks(27-35.5weeks) and the mean birth weight was 1528g(975-2980g). 2) The risk factors associated with the development of neonatal systemic fungal infection included long-term use of broad-spectrum antibiotics, prolonged hyperalimentation, prolonged use of aminophylline and steroid, and endotracheal intubation. 3) The most common presenting clinical manifestations were temperature instability, feeding intolerance, and apnea. 4) In laboratory studies, blood, urine, and CSF culture positivity was 92.8%, 92.8%, and 10.7%, respectively and renal and cranial sonogram were helpful to evaluate the renal and CNS involvement. 5) The principal treatment was intravenous amphotericin B administration for 4 weeks. The side effects, such as renal toxicity, hepatotoxicity, hypokalemia, and vomiting, developed but were reversible. 6) The mortality rate was 7.1%, and ventriculo-peritoneal shunts was performed in 3 cases who had fungal meningitis for the management of postmeningitic hydrocephalus. CONCLUSION: For was beformedin the diagnosis of neonatal systemic fungal infection is very difficult and the mortality is high, we recommend that antifungal therapy be initiated in clinically ill infants who are not responsive to antibiotic therapy and have negative culture findings and have some of the risk factors associated with systemic fungal infection.

The authors reported the cases of 23 patients with aneurysms measuring 2.5 cm or greater in diameter found during 7 years period in which we performed 596 operations for aneurysm of the 23 patients, 14 were treated by direct operation, 3 by internal carotid ligation with or without bypass surgery, 2 by trapping, 1 by wrapping and the other 3 by conservative therapy. The overall incidence of giant aneurysms was 3.9% but varied according to location; 9 cases were located on the internal carotid artery; 8 were on the anterior communicating artery; 5 were on the middle cerebral artery. 14 patients had hemorrhagic attacks, 7 had mass effects from the aneurysm, and 2 had ischemic events. Overall favorable outcome was 65% and the mortality was 13%. Based on the review of the literature, the appropriateness of surgery and surgical methods are discussed.

It has been widely accepted that the detachable balloon catheter technique is the treatement of choice in thecarotid-cavernous fistula and in the unclippable giant aneurysm at the cavernous or petrous portion of theinternal carotid artery. The authors successfully treated one case of the carotid-carvernous fistula and one caseof giant aneurys, located in petrous portion of the internal carotid artery using Debrun's latex datachableballoon catheter technique. In thecase with carotid-cavernous fistula, the only fistula was occluded with adetachable balloon, presserving the intrenal carotid artery. In the aneurysm case, both internal carotid arteryand aneurysm itself were completely occluded with 3 latex detachable balloons. Both patients have nocomplications. The authors will describe and discuss the Debrun's latex detachable balloon catheter technique.

In order to have the statistical basis of intracranial aneurysms, the authors analyzed the cases of angiographically proven intracranial aneurysms which were admitted to the department of neurosurgery, Seoul National University Hospital from Sep. 1957 to June 1988. The results of analysis were summarized as follows; 1) Total number of patients was 564 and 64 patients had multiple aneurysms, so total number of aneurysms was 647. Peak age incidence was in the 5th & 6th decades and male to female ratio was 1 : 1.2. 2) Location of aneurysms were anterior communicating artery(32%), posterior communicating artery(28.1%), middle cerebral artery(21.5%) in the order of frequency. Posterior circulation aneurysms comprised 7.1% and multiple aneurysms were 11.3%. 3) Among 647 aneurysms, 368 aneurysms were neck-clipped(56.9%), and operative mortality was 4.9%. 4) After 1983, 300 patients of 344 aneurysms were admitted to the neurosurgical department. The size of aneurysm was most frequent in 6-10 mm in diameter(49.4%) and 5 giant aneurysms were detected. 5) Among 344 aneurysms, 253 aneurysms were neck-clipped(73.5%) and operative mortality were lowered to 2.4%. 6) Among 300 patients 287 patients had ruptured aneurysm. Angiographic spasm was detected in 32.1% and symptomatic spasm was in 19.5%. 7) Hydrocephalus was detected in 36.2% during the period of admission and follow-up. 8) Anterior communicating artery aneurysms ruptured most frequently among the multiple aneurysms. 9) Clinical state on admission was an important factor for the outcome and preoperative clinical state was related to the operative outcome and mortality.

Evaluation of postpneumonectomy space (PPS) by CT in patients with lung cancer for operation-related complication or tumor recurrence is critical, but often difficult. We retrospectively analysed CT scans of 38 patients who underwent pneumonectomy for lung cancer. CT scans were obtained on 7-10th post-operative day for baseline image and at varying intervals of 2 to 24 months thereafter. Usual postoperative findings in patients without complication included mediastinal shifting, changes in subpleural space, changes in parietal pleura, and herniation of contralateral lung. Four patients had postoperative complications including empyema(n=3) and bronchopleural fistula(n=2). Twelve patients showed findings of tumor recurrence such as lymph node metastasis, local recurrence, and pericardial and contralateral pleural effusion. By comparing follow-up CT with baseline CT, we were able to detect early cancer recurrence and postoperative complications. Our results indicate that serial chest CT play an important role in the evaluation of the patients who underwent pneumonectomy for lung cancer.
