The purpose of this study was to compare surface roughness and bone formation around two types of threaded commercially pure titanium implants manufactured by two different companies. The test implants were manufactured by Sumin synthesis dental materials Co. (Avana, Busan, Korea), while the controls were manufactured by Nobel Biocare (MK II, Goteborg, Sweden). To compare bone formation adjacent to newly product with Branemark MK II implant, surface roughness was measured by Accurate 1500M and histomorphometric analysis was done. The results were as follows : 1. Measurement of surface roughness showed that Avana implant had a slightly more irregular surface compared with Branemark implant. 2. In the light microscopic studies, no infiltration of inflammatory cells nor the giant cells wee observed on both groups. 3. In th light and fluorescent microscopic studies, the amount of osseointegration and the extent and the timing of bone formation were similar. 4. There were no statistically difference between two groups in the average bone to implant contacts. Branemark implant ; 67%(SC 23%), Avana implant ; 70%(SD 16%). Comparing with Branemark implant, Avana implant made of CP grade II titanium showed similar good bone healing, formation and osseointegration.

Neck circumference is associated with a distinctive fat storage process that confers additional metabolic risk. Hence, this study aimed to investigate the correlation between baseline neck circumference and the incidence of cerebrovascular disease using a prospective community-based sample of Korean adults over 12 years of follow-up, after controlling for selected covariates. Methods: Participants with non-cerebrovascular disease were divided into 4 groups (Q1–Q4) based on their baseline neck circumference. Cox proportional hazards analysis was used to calculate hazard ratios and 95% confidence intervals (CIs) to evaluate the relationship between neck circumference and cerebrovascular disease incidence over a 12-year period. Results: Among this study’s 3,662 participants, 128 (3.50%) developed cerebrovascular disease. The incidence of cerebrovascular disease increased from 2.2% in Q1 to 4.3% in Q2, 2.5% in Q3, and 5.0% in Q4. When compared to Q1, the relative risks of cerebrovascular disease development were 0.57 (95% CI, 0.25–1.31), 0.86 (95% CI, 0.38–1.96), and 0.79 (95% CI, 0.30–2.07) in man and 1.86 (95% CI, 0.66–5.20), 3.50 (95% CI, 1.25–9.86), and 4.71 (95% CI, 1.50–14.77) in woman in Q2, Q3, and Q4, respectively, after adjusting for most risk factors related to cerebrovascular disease. Conclusion: The relationship between neck circumference and cerebrovascular disease was stronger in woman than in man, indicating potential differences between the sexes. These results are meaningful for evaluating and surveilling neck circumference as a promising tool for identifying subgroups of vulnerable and at-risk populations.

Clinical observation was carried out for 147 patients with mucocutaneous lymph node syndrome (MCLS) who were admitted to the Department of Pediatrics, Wonju Christian Hospital during the period from June, 1983 to June, 1992. A spinal tap was performed on 114 of these patients and the following results were obtained. 1) The incidence of aseptic meningitis in patients with MCLS was 52.6%. (60 cases of the 114 cases who had spinal taps (52.6%).) 2) The predominent age group for aseptic meningitis was 6 months to 1 year of age (35%). 3) For the majority, the value of glucose and protein in the CSF were within normal limit or only mildly elevated. 4) The neurologic manifestations associated with aseptic meningitis in patients with MCLS were irritability (78.3%), vomiting (25.0%), nuchal rigidity (11.7%), convulsion (5.0%) and facial nerve palsy (1.7%) in that order.

OBJECTIVES: This study compared attitudes toward antipsychotic treatment according to awareness of the name of their illness in patients with schizophrenia. METHODS: Information on sociodemographic and clinical characteristics, including awareness of the importance of antipsychotic treatment, was obtained through a self-report questionnaire. The Drug Attitude Inventory (DAI) was administered. The data were compared according to awareness of the name of their illness. RESULTS: The study analyzed data for 199 patients with schizophrenia. Of these, 115 patients (57.8%) were aware that their illness was called schizophrenia, while 84 patients (42.2%) knew it by their psychotic symptoms or as another mental illness, such as depression. The patients aware of the name of their illness had significantly longer durations of illness and higher scores on the DAI. They were significantly more likely to have stopped taking medication on their own accord and to agree with the importance of antipsychotic treatment. Statistical significance was sustained in a logistic regression analysis after adjusting for the duration of illness and study site, except for the DAI score, which had borderline significance (p=0.055). In subjects with duration of illness > or =5 years, patients aware of the name of their illness had significantly higher scores on the DAI. CONCLUSION: Awareness of the name of their illness was associated with awareness of the importance of, and a positive attitude toward, antipsychotic treatments in patients. Psycho-education, including telling the patient the correct name of his or her illness, might be needed for maintaining antipsychotic treatment in patients with chronic schizophrenia.

We performed both peripheral and coronary angiographies in 52 patients with an arteriosclerosis in lower extremities. The severity of arteriosclerotic narrowing of the coronany and peripheral anteries were compared on angiographies. An angiographic vascular score(AVS, 0-5) reflecting the number and the degree of stenosis in 12 lower extremity arteries and three major coronary arteries was assigned to each angiogram and the sum of scores in the lower extremity arteries was compared with the incidence of significant coronary artery disease(more than grade 3) and coronary score. Relation of incidence and severity of vascular stenosis and four risk factors(diabetes mellitus, hypertension, smoking, and hypercholesterolemia) was also analyzed. Thirty-four of 52 patients(65%) had an angiographically significant coronary artery disease. Thirteen of these 34 patients (38%) had no clinical symptom and sign of the ischemic heart disease. There was no statistically significant difference in the incidence and severity of coronary artery disease between high (more than 30) and low AVS group in lower extremity(P>0.14). All patients had at least one risk factor and 49 of 52 patients(94%) had multiple risk factors. Coronary angiography was normal in three patients with only one risk factors, and angiographically significant coronary artery disease existed in nine of 16 cases(56.3%) with two risk factors. 13 of 17 cases(76.5%) with three risk factors, and 12 of 16 cases(75.0%) with all four risk factors. There were no significant correlations between individual risk factors and incidence, severity of arteriosclerosis in coronary and lower extremity arteries. In conclusion, angiographic evaluation of the coronary artery disease in patients with lower extremity arteriosclerosis is necessary because of the high chance of coronary artery disease and difficulty in the prediction of coronary artery disease with a severity of the peripheral arteriosclerosis, presence of various risk factors, and clinical symptoms.

A nationwide survey was performed to know the distribution and prevalence of human Gymnophalloides seoi infection on western and southern coastal islands in the Republic of Korea. A total of 4,178 fecal specimens were collected from residents on 45 (24 western and 21 southern) islands, and examined by Kato-Katz and formalin-ether sedimentation techniques. Eggs of G. seoi were detected from 160 (3.8%) people living on 22 (13 western and 9 southern) islands. The prevalence varied by the location of islands; higher on western islands than on southern islands. The highest prevalence was found on Amtaedo (25.3%), followed by Cheungdo (25.0%), and Anchwado (20.9%) (Shinan-gun). A little lower prevalence was observed on Munyodo (13.3%), Shinshido (12.9%), and Sonyudo (10.3%) (Kunsan-shi). Of the remaining islands, the regions showing the prevalence greater than 5% included Kohado, Dallido (Mokpo-shi), Pyeongildo, Kogumdo (Wando-gun), and Keogumdo (Kohung-gun). A strong age predilection was noted (P < 0.05); 95% of the infected people were over 40 years old. Females showed a little higher prevalence than males. The results indicate that human G. seoi infection is more widely distributed than previously considered. Nine of 11 islands (excluding the 2 known areas Munyodo and Sunyudo) that showed greater prevalence than 5% are regarded as new endemic foci of G. seoi.

To evaluate the usefulness of MR in the osteomyelitis, we reviewed MR examinations of 14 patients with pyogenic osteomyelitis of the long bone. All 14 patients were confirmed to have osteomyelitis either surgically (13/14) or by aspiration (1/14). MRI was performed with 0.5R (n=8) or 2.0T (n=6) SE technique, and Gd-DTPA enhanced T1WI was obtained in 10 examinations. Anatomic location of lesions were femur (8/14), tibia (5/14),m and fibula (1/14). The marrow cavity and soft tissue were involved in 13/14, 12/14 respectively. The signals of both intraosseous and extraosseous infected area were iso to low signal intensity to muscles on T1WI and high signal intensity on PDWI & T2WI. Rim or diffuse enhancement of the marrow cavity and soft tissue were seen in all (10/10) cases. Sequestra, periosteal reaction. And cortical defect were found in 12/14, 10/14, 9/14. MR provided more accurate and detailed anatomic information including extent of disease and possible activity than bone scintigraphy, CT, or conventional radiography. We conclude that MR might be the choice of modality in the diagnosis of osteomyelitis of the long bone.

Although Soft tissue contrast and direct multiplanar imaging capability of MRI are well recognized, myelo Been the imaging modality of choice in evaluationg cervical root injury. We assessed the role of M compared its diagnostic accuracy with myelography in the evaluation of cervical root injury. MR finding Root injury in ten patients (55 roots) were retrospectively reviewed. In 26 explored roots (6 patin Frndings were compared with myelography and surgical results. In 29 roots (8 patients), which were By myelography or exploration, the MR findings were focal extraudral CSF collections (pseudomem In 21/29(72.4%, 8 patients), thickening of extradural roots in 4/29 (13.6%, 5 patients), and thickern Darn in 12/29 (41.4%, 6 patients) roots. T2-weighted axial image was superior to Tl weighted and Density-weighted images for delineationg root avulsion. The sensitivity and specificity of MRI were 7 93.3% respectively, while those of myelography were 83% and 90%. Overall diagnostic accuracy of Myelography were comparable (84.6% vs 87.5%). In conclusion, myelography is still considered as the Of choice in the preoperative evaluation of the cervical root avulsion because of its higher sensi, however, may obviate the myelography with some technical refinements.
