OBJECTIVE: Adult onset Still s disease is an acute systemic inflammatory disorder. There are no pathognomonic symptoms or specific laboratory abnormalities. In recent reports, serum ferritin concentration is increased in active disease phase and decreased after defervescence. Our purpose was to determine the clinical significance of serum ferritin as an indicator for disease activity. METHODS: Seven patients who were diagnosed as adult onset Still s disease at Samsung Medical Center between October 1994 and March 1997, were reviewed. In these patients we checked leukocyte count, ESR, CRP and serum ferritin concentrations at the time of diagnosis and during follow-up periods and recorded febrile events during follow-up periods. RESULTS: At the time of diagnosis and during febrile periods, the concentrations of ferritin were extremely high(927ng/ml to 96,650ng/ml normal 10-290.8 ng/ml). The values were unrelated to other manifestations of the disease or laboratory findings. The ferritin concentrations decreased rapidly after adequate treatment. Eleven febrile reattacks happened in 7 patients. Serum ferritin concentrations were increased in 8 febrile attacks, while leukocyte count, ESR, and CRP were increased in 5, 5, 6 febrile attacks respectively, There were 10 events of increased serum ferritin concentrations in 7 patients during follow-up periods and 8 events were related with fever. The increases of other laboratory tests were similar. CONCLUSIONS: In all patients, serum ferritin concentrations were increased at the time of diagnosis and closely related to fever. During follow-up periods, serum ferritin concentrations are helpful in monitoring disease activity and guiding decisions about treatment.

Relapsing polychondritis is a rare inflammatory disorder affecting the cartilaginous structures throughout the body. Although there is no pathognomonic laboratory tests, clinical features, when coupled with histopathologic findings, enable one to make a diagnosis of relapsing polychondritis. A 26-year-old man presented with purplish, swollen, and tender auricles and injected eyes. His symptoms had developed eight months ago and fluctuated irrespective of various medications such as corticosteroids and antibiotics. Histopathologic examination revealed loss of basophilic staining of the cartilage with some dissolution of its structures. Treatment was initiated with dapsone, However, the remission was too immediate to be considered as a effect of dapsone.

Closed interlocking nailing has become a common method of treatment of femoral fractures in adults. Interlocking nailing had a tendency toward rotational deformity and shortening. Therefore, we determined anteversion of the femoral neck after closed IM nailing of the femoral fractures. Femoral rotational deformity in both leg was determined by the construction of a line through the femoral neck and another through the transcondylar plane of the distal portion of the femur, using the CT scanning. We performed a retrospective study of 15 patients treated with closed IM nailing for femoral shaft fractures from 1989 to 1994. 1. The average differences in anteversion angle was 12.9 degree. 2. 3 cases(50%) in 6 cases that have difference more than 15° are accompanied with ispilateral injury of the knee joint and the lower leg. 3. Angle difference of the rotational deformity of proximal or distal femoral fractures is 15.5° which is 3.5° larger than that of fractures of femoral midshaft, 12.0°.

6.Comparison of the accuracy of implant digital impression coping
Journal of Dental Rehabilitation and Applied Science 2020;36(1):29-40
Purpose:
The purpose of this study was to compare the accuracy of impression taking method using the encoded healing abutment, scan body and pick-up impression coping with different implant angulations.
Materials and Methods:
Master model was fabricated by 3D printer and three implants were placed into the model with 0°, 10° and 20° mesial angulation. The abutments were secured to each implants and master model was scanned to make a reference model. Group P model was fabricated using pick-up impression copings and model was scanned after securing the abutments. Encoded healing abutment (Group E) and scan body (Group S) were secured on the master model and digital impression was taken using intraoral scanner 15 times each. Each STL files of test groups were superimposed with reference model using best fit alignment and root mean square (RMS) value was analyzed.
Results:
The RMS values were lowest in Group P, followed by Group S and Group E. Group P showed significant difference with Group S and E (P< 0.05) while there was no significant difference between Group S and E. Correlation between implant angulation and RMS value was significant in Group E (P < 0.05).
Conclusion
The pick-up impression coping method showed higher accuracy and there was no significant difference in accuracy between the healing abutment and the scan body. The clinical use of the encoded healing abutment is possible, but it should be used with caution in the case of angulated implant.

Liver function tests before treatment showed abnormalities of liver function tests during treatment, while 15(68. 2%) of 22 patients who had abnormal liver function tests before treatment showed abnormalities during treatment. In 12 of the 25 patients who showed abnormalities of liver function tests during treatment with allopurinol, allopurinol was stopped and all patients showed improvement of liver function tests. In remaining 13 patients, 10 patients were improved and other 2 patients showed only mild abnormalities of liver function tests despite of continuing allopurinol and 1 patient was lost during follow-up. CONCLUSION: Abnormalities of liver function tests were common during treatment with allopurinol. Most patiensts who had mild abnormalities of liver functions tests during treatment with allopurinol were improved regardless of continuing allopurinol.

BACKGROUND: Little data is available regarding hospitalized patients with nursing home-acquired pneumonia (NHAP). This is unfortunate because there is an increasing number of elderly persons who are living in nursing homes in Korea. The aim of this study was to compare clinical characteristics and treatment responses of NHAP with community-acquired pneumonia (CAP). METHODS: Patients with pneumonia who were admitted from eight nursing homes or from their own homes were enrolled between May 2007 and April 2009. Their clinical characteristics and treatment responses were reviewed retrospectively, and differences between the two groups were analyzed. RESULTS: Of 110 Patients with pneumonia, 66 (60%) were from nursing homes and their median age was 84. In the NHAP group, functional performance status was significantly poorer, classical symptoms of pneumonia were less severe, and multi-lobe involvement (on chest radiographs) was more frequent than in the CAP group. Patients with NHAP more frequently showed lymphocytopenia, anemia, hypoalbuminemia, hypoxemia, and elevated blood urea nitrogen on admission. The mean CURB-65 score was 2.2 in the NHAP group, higher than 1.7 in the CAP group (p=0.004), and multi-drug resistant pathogens were also highly identified in NHAP group (39% vs. 10%, p=0.036). The mean duration of antibiotic therapy was greater for the NHAP (12.6 days) than for the CAP group (6.6 days) (p<0.001). The mortality rate was 23% in NHAP group, which was significantly higher than 5% in the CAP group (p=0.014). CONCLUSION: NHAP should be more intensively investigated because of the higher frequency of multi-drug resistant pathogens and mortality than the CAP.

9.Comparative observations of lingualized occlusion and monoplane occlusion in the treatment of severe atrophy of edentulous mandible
Journal of Dental Rehabilitation and Applied Science 2018;34(2):127-136
The patient who has severely absorbed residual ridges, treatments are challenging to satisfy many factors: support, retention, stability, etc. The neutral zone or monoplane occlusion with non-anatomical tooth would be helpful to get additional retention and stability. The monoplane occlusion has been used long time because it can eliminate horizontal forces and many other advantages. The lingualized occlusion was introduced to improve chewing efficiency and esthetics. But from a stability aspect, it seems controversy between monoplane occlusion and lingualized occlusion. This case report shows the results of the treat two flat residual ridge patients using functional impression; piezography, and made 2 other dentures with monoplane and lingualized occlusion that patient can select denture.

OBJECTIVES:
To report analytic results about association factors related to effect of conservative treatment in surgically indicated single level lumbar spinal stenosis patient.SUMMARY OF LITERATURE REVIEW: There have been various reports about clinical outcomes and relative factors after surgical treatment of spinal stenosis. However, there are few reports about factors related to effect of conservative treatment in surgically indicated lumbar spinal stenosis patient.
MATERIALS AND METHODS:
We based on 40 patients who had visited our hospital from May 2010 to April 2016 who were traceable for at least three years. We analysed 20 patients who improved symptom and who didn't improved symptom then investigated association factors related to effect of conservative treatment. Clinical assessment was conducted using questionnaire and spinal canal's area and muscle amount were measured in the MRI.
RESULTS:
Average of the spinal canal of not-improved group is 91.29(±34.26) mm², improved group is 130.70 (±32.18) mm² and impoved group is wider (p=0.001). Muscle mass of improved group is 91.47(±9.43) cm², not-improved group is 79.26 (±14.35) cm², and improved group is wider (p=0.003). Repetitive strain and traffic accident were related in not-improved group (p=0.028). However, practiced stretching continuously were related to symptom improvement (p=0.022).
CONCLUSIONS
Association factors related to effect of conservative treatment are cases of wide spinal canal, wide muscle amount, repetitive sprain, traffic accident and stretching. A small muscle amount can be considered as a key factor related to surgical conversion.
