This study was conducted to investigate the causes of burn and emergency cares taken on the spot for the burn patient. study population included 161 burn patients admitted to 2 university hospitals and 1 general hospital in Taegu from November 1, 1987 to April 30, 1988. Patients or guardians were interviewed with a structured questionnaire. Out of 161 burn patients 111(69.8%) were males and 50(31.1%) females. Preschool children of 1-4 years old accounted for 29.8% of the total patients. Burns of children under 15 years of age took place at home in 91.0%, while 48.3% of burns of adult (15 years and over) males occurred at the working place, and 68.0% of adult females occurred at the home. Out of total burns occurred at home 39.8% took place at kitchen/dining room and 24.1% in the room. The most common cause of burns in children was the boiling water or hot food (74.3%). In adults the common causes were electrical burn(22.4%), hot water or food(19.0%) and explosion(12.1%) for males, and hot water or food(32.0%) and explosion(20.0%) for females. Common emergency cares for the burn taken on the spot were undressing(64.6%), pouring Soju(liquor)(13.7%), and pouring cold water(5.0%). There were a few cases who applied ash, soy or salt. To prevent burn, it is recommended to remodel the traditional kitchen and coal-briquet hole, to strengthen the safety control of LP Gas and LN Gas supply, to educate the public for the handling method for such gases, to strengthen the occupational safety control, to improve the safety device for the electric wire and socket, and to limit the temperature of hot water at home and public baths.

Lipomas of the heart are benign neoplasms and have rarely been described. Due to the fact that they normally cause no symptoms, diagnosis is often purely accidental. Because of the rarity of these tumors, it seems worthwhile to present an example studied at autopsy. It was associated with the sudden death of a 15-year-old boy. The tumor arose from the wall of the left ventricle and occupied the pericardial cavity, measuring 13x7x6 cm in size. The tumor was whitish-yellow, translucent, and soft. Microscopically, the tumor was composed of mature adipose tissue which extended between muscle fibers. This current case, the giant cardiac lipoma is believed to produce disturbances of the conduction system and distrubances of cardiac filling.

BACKGROUND: The purpose of this study was to identify the clinical and radiological outcomes of hook plate fixation for lateral end fracture of the clavicle and acromioclavicular dislocation. METHODS: There were a total of 20 cases with lateral end fracture of the clavicle and 16 cases with acromioclavicular dislocation. All patients were evaluated for range of motion, functional score by using Constant score, and American Shoulder and Elbow Surgeons shoulder index at just before implant removal and at final follow-up. Coracoclavicular distance was measured in acromioclavicular dislocation and bony union was evaluated in the lateral end fracture of the clavicle. RESULTS: The clinical outcomes and range of motion were increased at the final follow-up compared with just before implant removal in both the lateral end fracture of the clavicle and acromioclavicular dislocation. In acromioclavicular dislocation, all cases—except one—showed maintenance of reduction after implant removal. Moreover, in the lateral end fracture of the clavicle, all cases—except one—showed bony union. CONCLUSIONS: Hook plate fixation in the lateral end fracture of the clavicle and acromioclavicular dislocation resulted in good clinical and radiological results.

Injuries and pains of musculoskeletal joint in human body is common onset in industrialized world. However, muscle fatigue plays a very significant role in contributing causes of many pains associated with musculoskeletal joints. Based on this hypothesis, degree of muscle fatigue was investigated using electromyography measurement technique during isometric and concentric/eccentric muscle contractions. Different response of the muscle fatigue between two different muscle contractions (isometric and concentric/eccentric contractions) was examined by comparison of parameters which were median frequency, median power and RMS value. Healthy 16 young persons without previous musculoskeletal diesease history were tested with Noraxon Myosystem 2000 EMG measurement system. In this study, two different exercises were performed. First exercise was concentric/eccentric exercise. Second exercise was isometric muscle contraction. In the case of the isometric exercise, median frequency was decreased, but median power and RMS were increased. However, during the concentric/eccentric exercse, median frequency was increased, but median power and RMS were decreased. Both of those revealed that the pattern of the median frequency was W type, but median power and RMS were M type as time passed. In this study, the patterns of the muscle fatigue during concentric/eccentric exercise as well as isometric exercise were identified. It will be helpful to prevent musculoskeletal injury from over-working andexercising.

STATEMENT OF PROBLEM: In cases where bony defects were present, guided bone regenerations have been performed to aid the placement of implants. Nowadays, the accepted concept is to isolate bone from soft tissue by using barrier membranes to allow room for generation of new bone. Nonresorbable membranes have been used extensively since the 1980's. However, this material has exhibited major shortcomings. To overcome these faults, efforts were made to develop resorbable membranes. Guided bone regenerations utilizing resorbable membranes were tried by a number of clinicians. Bio-Gide. is such a bioresorbable collagen that is easy to use and has shown fine clinical results. PURPOSE: The aim of this study was to evaluate the histological results of guided bone regenerations performed using resorbable collagen membrane(Bio-Gide.) with autogenous bone, bovine drived xenograft and combination of the two. Surface morphology and chemical composition was analyzed to understand the physical and chemical characteristics of bioresorbable collagen membrane and their effects on guided bone regeneration. MATERIAL AND METHODS: Bioresorbable collagen membrane (Bio-Gide.), Xenograft Bone(Bio-Oss), Two healthy, adult mongrel dogs were used. RESULTS: 1. Bioresorbable collagen membrane is pure collagen containing large amounts of Glysine, Alanine, Proline and Hydroxyproline. 2. Bioresorbable collagen membrane is a membrane with collagen fibers arranged more loosely and porously compared to the inner surface of canine mucosa : This allows for easier attachment by bone-forming cells. Blood can seep into these spaces between fibers and form clots that help stabilize the membrane. The result is improved healing. 3. Bioresorbable collagen membrane has a bilayered structure : The side to come in contact with soft tissue is smooth and compact. This prevents soft tissue penetration into bony defects. As the side in contact with bone is rough and porous, it serves as a stabilizing structure for bone regeneration by allowing attachment of bone-forming cells. 4. Regardless of whether a membrane had been used or not, the group with autogenous bone and Bio-Oss. filling showed the greatest amount of bone fill inside a hole, followed by the group with autogenous bone filling, the group with blood and the group with Bio-Oss. Filling in order. 5. When a membrane was inserted, regardless of the type of bone substitute used, a lesser amount of resorption occurred compared to when a membrane was not inserted. 6. The border between bone substitute and surrounding bone was the most indistinct with the group with autogenous bone filling, followed by the group with autogenous bone and Bio-Oss. filling, the group with blood, and the group with Bio-Oss. filling. 7. Three months after surgery, Bio-Gide. and Bio-Oss. were distinguishable. CONCLUSION: The best results were obtained with the group with autogenous bone and Bio-Oss. filling used in conjunction with a membrane.

A 81-year-old man was referred for respiratory failure by emergency medical technicians. He admitted at intensive care unit for ventilator treatment. Several hours before admission, he took sildenafil 100 mg for erectile dysfunction without prescription. The episodes of hemoptysis occurred several hours later. Computed tomography revealed multifocal diffuse ground-glass attenuation in both lungs. And the more we performed bronchoalveolar lavage, the more the color of it was turned into red. We treated him with empirical antibiotics and tranexamic acid, and hemoptysis was stopped in one day after admission. But in the 5th admission day, he died from sepsis combined with pneumonia caused by Acinetobacter baumannii abruptly.

An intraosseous epidermal cyst is a rare benign cystic lesion. It is thought to result from congenital factors or trauma and can lead to bone destruction because the cyst develops at the soft tissue around the bone. Radiological findings of intraosseous epidermal cysts are a well-defined radiolucent lesion, with cortical expansion. It is important to differentiate an intraosseous epidermal cyst with other disease developed at distal phalanx because its clinical and radiological findings are similar. We report two rare cases of intraosseous epidermal cysts that developed at the distal phalanx.

A case of Wegener's granulomatosis is described, with special attention focused on the typical histologic findings and involvement of both middle ear and lung. The patient is a 37-year-old man presented with four-month history of cough and sputum. He had a past history of surgery of both ears because of otitis media followed by left facial palsy. Chest radiographs showed variable sized ill defined nodules in both lower lobes with internal airspace consolidation. Histologic preparations of the open lung biopsy specimens demonstrated a diffusely scattered palisading micro and macrogranulomas with central focus of neutrophils and necrotic collagen surrounded by histiocytes, histiocytic giant cells. Fibrinoid necrosis involved blood vessels and lung parenchyma. Chronic inflammation, diffuse granulation tissue formation and irregular fibrosis are also found in the lung parenchyma. The histologic findings of middle ear which was previously biopsied showed scattered palisading ill defined microgranulomas mixed with fibrotic tissue.

We report two cases of recurrent extramarnmary Pagets disease after wide local excision. Both cases involved the scrotum and the penoserotal junction, respectively. On histopathological examination, we could observed many Paget cells confined to the epidermis and the hair follicle, but not invading the underlying dermis in both cases. There was no evidence of internal malignancy. Both cases were treated with wide local reexcision.
