1.Radiodermatitis from Occupational Exposure to 192Ir.
Korean Journal of Occupational and Environmental Medicine 1998;10(1):128-135
Portable gamma radiography for nondestructive testing with 192Ir is commonly used in various industrial fields to defect possible internal defects of metals in pipelines, tanks, bridges, ships and so forth in Korea. Compared to the numerous researches about biologic effects and potential risks of radiation, only a Jew papers were reported about radiodermatitis from occupational exposure to 192Ir. In this study, we investigated six patients with occupational radiodermatitis with developed during portable gamma radiography for nondestructive testing with 192Ir. All six patients had developed radiodermatitis on their hands and fingers. They noticed painful swelling, erythema, and bullae on their fingers or palms 1 to 2weeks after exposure. Three patients suffered from chronic fibrosis and recurrent ulcerations. We also discussed about the working situation of our patients and reviewed the literatures about the radiodermatitis from occupational exposure to 192Ir. In conclusion, we think ionizing radiation, though it is a useful tool in industry, must be carried out in accordance with radiation protection rules and regulations.

Hypertrophic cardiomyopathy has been a well-known genetical transmitted disease entity with the advance of echocardiography. We have recently experienced a family with hypertrophic cardiomyopathy proved by noninvasive methods including chest x-ray,, electrocardiography and echocardiography. The propositus of this family was a 21 year-old solier who was admitted because of exertional dyspnea during military exercise. Both he and his sister had severely affected hearts with typical echocardiographic findings, asymmetrical septal hypertrophy(ASH) and systolic anterior motion of the anterior mitral leaflet(SAM). The clinical study is reported with the concerned literatures.

BACKGROUND: The 5α-reductase inhibitor finasteride blocks the conversion of testosterone to dihydrotestosterone(DHT), the androgen responsible for androgen- etic alopecia in genetically predisposed men. OBJECTIVE: The purpose of this study was to determine the efficacy of finaster- ide treatment according to the type of androgenetic alopecia in Korea. METHODS: 196 patients with finasteride(1.25mg/day) were registered in this study and 68 patients were followed over 8 months. Efficacy was evaluated by globa1 photographs, investigator assessment of clinical change,and patients' self assessment via self administered hair growth questionnaire. RESULTS: Patients' self-assessment demonstrated that finasteride treatment slowed hair loss, increased hair growth, and improved appearance of hair. These improvements were corroborated by objective assessments after 4 months of treatment. Adverse effects such as sexual dysfunction were minimal. CONCLUSION: Oral finasteride 1.25mg/day slowed the progression of hair loss and increased hair growth in clinical tria1s of men with androgenetic alopecia over 8 months. With its generally good tolerability profile, finasteride is a new approach to the management of this condition, for which treatment options are few.

To evaluate the clinical efficacy of emergency cervical cerclage in the treatment of advanced cervical incompetence, a prospective clinical trial was performed in 18 patients with advanced cervical incompetence at 20 to 25 weeks gestation. Modified McDonalds operation with or without transabdominal amniocentesis was used for cervical cerclage. Pregnancy was prolonged for a sufficient time to deliver viable fetuses in 56.3% of patients. The median procedure-to-delivery interval was 8.6 (range 0.1 to 20.5) weeks for the entire group, and 13.9 (range 6.5 to 20.5) weeks for 9 patients who achieved live birth. The median gestational age at delivery was 38.6 (range 28.3 to 41.0) weeks for the live infants. The median birthweight of the live infants was 3062 g (range 1050 to 3620 g). The lack of significant matemal morbidity combined with the results for the fetus-infant supports further efforts in this area.

BACKGROUND: Although drug eruption refers to a common dermatologieal condition, there are numerous setbacks in the diagnosis. In addition there are no annual average prevalence rates of drug eruptions according to time sequence in Korea. OBJECTIVE: This study attempts to detme the clinical features and causative drugs of drug eruptions, the diagnostic value of various skin tests and to evaluate the dome,stic annual average prevalence rate of drug eruptions according to time sequence. METHOD: 270 patients with drug eruptions were reviewed clinically. In 103 patients, intradennal, patch and scratch-patch tests were performed using suspected drugs. The annual average prevalence rate of drug eruptions was calculated from 10 different general hositals in Korea. RESULT: Exanthematous eruptions(49.3), fixed drug eruptions(30.1), and urticaria(10.0%) were the common types of drug eruptions. The common causative agents were antibiotics/antimicrobials, antipyretics(NSAIDs, and CNS depressants. 52 patients out of 103 had positive results after at least one skin test with suspected drugs. CONCLUSION: In our study, we were ahle to obtain somewhat meaningful results basnl on data from the combination of various skin tests. As a result, physicians need to prescrible drugs with care.

PURPOSE: To analyze the clinical features and treatment outcome of Langerhans' cell histocytosis. MATERIALS AND METHODS: From August 1996 to June 2013, 28 patients who histologically proven with LCH were analyzed of medical records, radiography, pathologic character retrospectively. RESULTS: A total of 28 cases of LCH including 22 child has been reported. Onset age was 0.6 to 51 years old, occurred in the average age was 14.8 years. Follow-up period was 6 months to 134 months average was 44.6 months. The M:F ratio was 2.5:1. The initial symptoms was pain in 18 cases, 5 cases of pathologic fracture, 3 case of palpable mass, 1 case of discovered by accident in radiography, 1 case of torticollis. In radiological examination osteolysis was seen all cases, 7 cases showed a periosteal reaction, 1 case showed soft tissue extension. Clinical type of all cases were eosinophilic granuloma. 25 cases were classified as unifocal disease and 3 cases were multifocal single systemic diseases. In all cases, incisional biopsy was performed. After histologic confirmed, 14 cases was treated with curettage or surgical excision of the lesion and the other 14 cases were followed up without treatment. There is no death during follow up period. 11 cases has no radiological improvement after 3-6 months observation, intralesional steroid injection was performed. CONCLUSION: Patients with LCH who has rapid systemic onset is very rare, so if you meet the young children who suspected LCH, you shoulder avoid the examination which cause excessive radiation exposure to the young patient. In order to confirm the diagnosis of disease, biopsy is needed. Close observation after confirmed by histological method will bring the satisfactory results. But the patients who had pathologic fracture or wide bone destruction already may need curettage and bone grafting to lesion or internal fixation. The lesion which has no radiological improvement after 3-6 months observation or appear with pain interferes daily life may need local steroid injection as a good treatment.

PURPOSE: With advances in various treatment modalities, limb salvage surgery has been commonly used in osteosarcoma of extremities. An alternative method for skeletal reconstruction is reimplantation of the tumor bearing bone following extracorporeal irradiation (ECI). We report the long-term results of ECI autograft in aspect of the oncological and functional outcomes, and complications. MATERIALS AND METHODS: We retrospectively reviewed 31 osteosarcoma patients who underwent reconstruction with ECI between July 1995 and January 2006. There were 24 males and 7 females with a mean age of 24 (7-74 years) and a mean follow-up of 117 months (17-177 months). Twenty-five cases were reconstructed with ECI autograft, 6 cases with ECI autograft-prosthesis composite. The pathologic subtypes were conventional in 29 cases, periosteal in 1 case, and parosteal in 1 case. The most common location of tumor was distal femur (15 cases) followed by humerus (3), proximal fibula (3) and proximal tibia (3). Musculoskeletal Tumor Society (MSTS) score was used for functional evaluation. The overall survival rate, local recurrence, complications were analyzed. RESULTS: The overall survival rate was 80.6% and the disease-free survival rate was 64.5%. Five patients died of distant metastasis. One patient required above-knee amputation due to local recurrence. All of them, twenty-three complications occurred, which included nonunion in 7 cases, deep infection in 5 cases, joint instability in 4 cases, metal failure in 2 cases, Limb-length discrepancy (LLD) in 2 cases, periprosthetic fracture in 1 case, epiphyseal collapse in 1, local recurrence in 1 case. The mean MSTS functional score was 62.5%. CONCLUSION: Extracorporeal irradiated autograft can be achieved relatively good result in aspect of oncological and functional aspect, but is needed to be additional research about occurring many complications. The reconstruction with ECI after intercalary or fragmentary resection is effective reconstruction in aspect of oncological and functional result, complications.

BACKGROUND AND PURPOSE: Radioopaque lesions are commonly seen in patients who received thoracic radiotherapy for various kinds of thoracic neoplasm, But therir exact diagnos are sometimes uncertain. PATIENTS AND METHODS: We examined simple chest radiograph and computed tomogram(CT) of 69 patients who received thoracic radiotherapy for lung cancer and were follow up at least 6 months in Yeungnam University Medical Center. RESULTS: Of the 69 patients. thirty-eight patients showed radioopaque lesions in their chest radiographs except radiation fibrosis; radiation pneumonitis was witnessed in 24 patients. infectious pneumonia in 8 patients, and recurrence in 6 patients. In radiateionpneumonitis patients, the pneumonitis occurred usually between 50 to 130 days after receiving radiation therapy, and interval between pneumonitis and fibrosis is 21 to 104 days. Simple chest radiographs of radiation pneumonitis(24 patients) represented ground glass opacities or consolidation in 4 cases(type I, 17%), reticular of reticulonodular opacities in 10 cases(type II, 42%), irregular patichy consolidations in 2 cases( type III, 8%), and consolidation with fibrosis in 8 cases(type IV, 33%), CT represent ground glass opacities or consolidation in 5 cases(type I, 29%), irregular nodular opacities in 3 cases(type II, 19%), irregular opacity beyond radiation fields in 3 cases(type III, 18%), and consolidation with fibrosis in 6 cased(typeIV, 35%). The CT of four patients who represented type II on simple chest radiographs reveal type I and III, and CT of two patients with clinical symptoms who had no abnormal finding on simple radiograph revealed type I. CONCLUSIONS: In conclusion, computed tomogram is superior to the simple radiograph when trying to understand the pathologic process of radiation pneumonitis and provide confidence in the diagnosis of radiation induced lung disease.

A 63 Year-old-lady has had substernal chest pain on exertion for 8 years. The chest pain has been increased over the last 3 years. A continuous murmur was heard at the left second to third inercostal spaces along the left sternal border. The electrocardiogram showed the inverted T-waves in the precordial leads. The right heart catheterization revealed 5% oxygen step up between RV and PA. The right sided pressures were normal. The coronary arteriography revealed markedly tortuous vessels starting shortly after the left main stem coronary artery was normally originated. One of the large vessel was shown to be drained into the pulmonary artery. In the operation room, without using heart-lung machine this abnormally drained vessel was simply ligated at it's draining site into pulmonary artery. After the operation the patient is feeling well with little symptoms and the continuous murmur is no longer heard.
