PURPOSE: Moyamoya disease is a primary vascular disease characterized by stenosis that is followed by occlusion of the intracranial portion of the internal carotid artery and other vessels of the circle of Willis. Since there has not been any specific reports about clinical manifestation in children, we plan to study on clinical manifestation through these patients who have moyamoya disease. METHODS: We have reviewed our case of moyamoya disease in patients admitted to Yonsei University College of Medicine and analyzed their age & sex distribution as well as clinical manifestations, together with brain CT and angiographic findings. RESULTS: The results were as follows: 1) Fifty cases of moyamoya disease were encounted during a 10-year period. 2) The male to female ratio was 1:2.3 and mean age was 6.3 years old. 3) The most common chief complaint on admission was hemiparesis followed by convulsion. 4) 42 patients(84%) showed infarction on brain CT and only 5 patients(10%) showed hemorrhage. Most common lesion was frontal lobe. 5) Bilateral occlusion of the internal carotid arteries was most common site of lesions on cerebral angiography.

Acrylonitrile is most commonly used aliphatic nitrile compounds characterized by the structural formula R-C=N and used mossy to make acrylic fibers, plastics, synthetic rubber, and wall coverings. In recent, because of its extensive usage and the rapid expansion of the chemical industry, many poisonings have been reported and many studies on its health effects have been performed. Acute toxicity resembles cyanide poisoning and results mainly in effects on the nervous system. High exposure also can cause temporary damage to red blood cells and the liver and can cause lead to death. Because long-term occupational exposure to the acrylonitrile has been with cancer in humans, the U.S EPA classifies acrylonitrile as probable carcinogen. For this reason, The federal government has developed regulations and advisories to protect individuals firm the potential health effects of acylonitrile in the environment, but there are few studies, case reports and regulations of the government in our country. We experienced acute poisoning caused by acrylonitrile inhalation that occurred in an industrial accident. So, we report this case with literature reveiw.

The treatment of acetabular fractures is composed of operative and conservative methods, however, they are still controversial. Generally, because the acetabular fracture involves the joint surface and one sequalae such as post-traumatic arthritis can follow treatment, therefore an accurate reduction and postoperative early mobilization to obtain the prevenation of joint stiffness and arthritis are required. In order to achieve these purposes, we have studied and done a comparative survey between conservative and operative treatment on 55 patients with acetabular fractures, who were treated at our department from Jan. 1982 to Dec. 1988. Results were obtained as follows. 1. The prevalent age was the third decade and the cause of injury was traffic accidents in the majority. 2. The most common type of fracture was a posterior wall by Letournel classification. 3. Satisfactory results of operative treatment were 76% and conservative treatment 47%. 4. The complications were post-traumatic arthritis, ectopic ossification, peroneal nerve palsy and skin infection. 5. In the majority of displaced acetabular fractures, ORIF was recommended.

Histiocytosis X(Langerhans cell histiocytosis) is a rare prolifertive disorder of Langerhans cells that includes Lettere-Siwe disease, Hand-Shiiller-Christian his ase and eosinophilic granuloma. Since many authors have reported in anintermediate and poarl classified form histiocytosis X has a namenclatural had nosologic problem. We report a case benign cutaneous variant of histiocytisis X. A four-month-old boy had shown multiple skin-colour papules on the trunk, head and nik for one month. Extensive in- vestigations failed to detcct any systemic involvement. The clixron microscopic findings of the skin biopsy specimen were Qefinitely diagnostic for histiocytosi. X Since he did not sbow evidence of internal organ involvernent and any further progression of he skin lesion, no therapy was given. Over the next two months the disease underwent spontane us and complete remission.

BACKGROUND: In these days of increasing need for medical treatment, and the trend of changing lifestyles for personal health care, the position of medical treatment has led to the increase of careful and various services to every member of the community. But the reality of medical treatment, including the present situation of the emergency room in general hospital is recognized as the cause of those dissatisfactions and complaints of both patients and their caregivers. So this study aims at contributing to the harmonious relation between doctor and patient. METHODS: This study has been carried out by the questionnaire method on the basis of the relatively reasonable 331 papers among 430 questionnaire papers of the patients and their caregivers hospitalized by way of the emergency room in Cheonju Yeong Dong Hospital from Sep. 1994 to Apr. 1995. RESULTS: Among 331 subjects of this questionnaire, there were 121 male patients(36.6%), 76 female patients(23.0%), 80 male caregivers(24.2%), 54 female caregivers. The subjects were compaced of 23 teenagers(7.8%), 74 in their twenties(22.4%), 135 in their thirties(40.8%), 52 in their fourties(15.7%), 29 in their fifties(8.8%), 12 in their sixties(3.6%), 6 in their seventies(1.8 %). Both patients and their caregivers seemed to have a great dissatisfactions and complaints, which can be extraneous to medical treatment. Many patients complained of the unbearable situations such as delayed pain control before after a first-aid treatment, as well as various poor condition of medical treatment in emergency room. Their caregives complained of the lack of a thought explanation of diagnosis and prognosis, as well as the tedious waiting time before taking medical teratment. There were many cases where the emergent patients took medical treatment with some dissatisfa'ctions and complaints of medical staffs or medical donditions. CONCLUSIONS: When using the emergency room in a general hospital, both patients and their caregivers experiance a great deal of dissatisfactions and complaints, which can be followed by a distrust of the hospital and an obstacle of medical treatment. The medical staff, such as the hospital authorities, doctors, and nurses should make various improvements upon the medical conditions of the emergency room in general hospital.
