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.

One hundred eighty infants with oxygen therapy who were under 2,500gm birth weight or under 37 weeks of gestational age, were examined between January 1990 and November 1992. We performed clnical analysis and results were as follows. 1) Fifty six infants (31.1%) were diagnosed as retinopathy of prematurity. 2) The first examination was performed at 2.5 weeks of life on average, and the retinopathy of prematurity was diagnosed at 3.8 weeks on average. 3) The incidence of retinopathy of prematurity was highly associated with low birth weight (< or =1,890 gm), low gestational age ( < or =33.1 weeks), and high oxygen concentration with long duration (FiO2> or =0.4 over 1 week)(P<0.005). 4) Other associated risk factors were idiopathic respiratory distress syndrome, anemia, neonatal hypoxia and sepsis.

PURPOSE: This study attempted to identify influential variables on types of smoking in adult smokers, which have been derived from Q-study. METHODS: A survey was conducted with 328 adult smokers at community settings in Seoul, South Korea from April 2006 to July 2006. To identify the influential variables related to smoking, variables from the Trans-theoretical model(i.e., self-efficacy for smoking abstinence, smoking temptation, process of change, decisional balance(pros and cons)) and nicotine dependency were analysed by ANOVA. Post-comparison tests were also done. RESULTS: The scores of nicotine dependency and smoking temptation were higher in habitual craving types than any other types, while the scores of self-liberation and self-efficacy for smoking abstinence were higher in self control types than any other types. CONCLUSION: Specific smoking intervention methods for each of the smoking types needs to be developed, based on how different groups of individuals gets into a decisions to quit smoking within their contexts.
