To evaluate the atlantoaxial instability in children with Down syndrome, the authors analyzed the 97 children with Down syndrome attending to 2 schools for handicaped children in Pusan. The rsults of study were as follows; 1)The incidence of atlantoaxial instability in 97 individuals with Down syndrome was 8(8.3%) in neutral position and in 10(10.3%) in flexion, respectively. 2) The mean atlantoaxial gap was significantly higher in patients with Down syndrome than in the control group(P<0.05). 3) The mean atlantoaxial gaps in patients with Down stydrome according neck position was significantly higher in flexion(3.27 +/-1.08mm)than in neutral(2.63 +/-1.18)(p<0.05). 4) When mean atlantoaxial gaps of patients with Down syndrome were analyzed according to age groups, young age groups were statistically higher than old age groups in flexion position(p<0.05) but no statistically signigican differences were in neutral position. 5) The mean atlantoaxial gap of obese group was slightly higher than those of non-obese group but no statistically significant difference was noted(p<0.05).

Allergic contact dermatitis is a prototype of delayed hypersensitivity reaction. Langerhans cells, keratinocytes and T lyrnphocytes play major roles in the pathogenesis of allergic contact dermatitis. We observed Langerhans cells and keratinocytes in contact sensitized epidermal sheets of mice and performed mixed epidermal cell lymphocytes reaction with normal epidermal cells and contact sensitized epidermal cells to determine the lymphocyte stimulating capacity of contact sensitized epidermal cell. We obtained following results : 1. The Langerhans cells were decreased in number and morphologically damaged in contact sensitized epidermis. 2. Ia antigen expression on keratinocytes was detected in almost all contact sensitized epidermal sheets. 3. The allogeneic lymphocyte stimulating capacity of contact sensitized epidermal cells was greater than that of normal epidermal cells. 4. The allogeneic lymphocyte stimulating capacity of contact sensitized epiderrnal cells was lost after treatment of epidermal cells with anti Ia antibody and complement. From these results, it is conceivable that the contact sensitized epidermal cells can amplify the immune reactions by stimulating the lynphocytes which are infiltrated in contact sensitized epidermis.

BACKGROUND: Emergency Medical Technicians can do emergency care only under the control of the physicians. Emergency medical services system(EMSS) in Korea is now extended from the level of basic life support(BLS) to advanced life support(ALS). Unfortunately we don't have any official medical control system yet. We and regional EMSS, 119 rescue team(BLS), have had monthly joint meeting to validate and improve the prehospital care since August, 1998. METHODS: From August, 1998 to February, 1999, 1,708 patients were transported to Ewha Mokdong Hospital by regional 119 rescue team. Eight hundred and six(47.2%) run record were collected and analyzed. The appropriateness of the prehospital care were evaluated based on the comparison of assessment data and treatment data in each run record. The run record were divided into 5 groups; 1) necessary-adequate, 2) necessary-inadequate, 3) necessary-undo, 4) unnecessary-done, and 5) unnecessary-undo. 1) and 5) were judged as acceptable, and 2), 3), and 4) as unacceptable. RESULTS: Among 806 transported patients, 60.8% required one or more emergency care. 21.0% of required care were not provided, and 20.7% of provided care were not adequate. 78.8% of unprovided and 75.9% of inadequate care were 'airway and oxygen supply'. Overall unacceptable rate was decreased from 31.7% to 17.0% during first 5 months, but it rose up again to 24.7% after 2 months. Cardiopulmonary resuscitation(CPR) was performed in 29 prehospital cardiac arrest victims and admitted to ICU in 5 cases. CPR was not provided in 8 necessary situations, and unnecessary CPR was done in 3 cases. CONCLUSION: EMSS in Korea also need a kind of medical control system, even for BLS level. Major portion of the quality assurance program could be 'airway and oxygen supply', but attention should be focused in cardiac arrest victims and CPR. Record keeping and reliance of run record data are now pending problems. Fire department should develop a formal medical control system and the referring hospital should have an organization for maintaining the quality of prehospital care.
