1.Nasal Diseases and Its Impact on Sleep Apnea and Snoring.
Sleep Medicine and Psychophysiology 2004;11(1):17-21
Nasal congestion is one of the most common symptoms of medical complaints. Snoring is caused by vibration of the uvula and the soft palate. Nasal obstruction may contribute not only to snoring and obstructive sleep apnea (OSA) but also impair application of continuous nasal positive airway pressure (CPAP), which is the most widely employed treatment for OSA. Total or near-total nasal obstruction leads to mouth breathing and has been shown to cause increased airway resistance. However, the exact role of the nasal airway in the pathogenesis of OSA is not clear and there is no consensus about the role of nasal obstruction in snoring and sleep apnea. Some reports have failed to demonstrate any correlation between snoring and nasal obstruction. On the other hand, opposing reports suggest that nasal disease may cause sleep disorders and that snoring can be improved after nasoseptal surgery. Reduced cross-sectional area causes increased nasal resistance and predisposes the patient to inspiratory collapse of the oropharynx, hypopharynx, or both. Discrete abnormalities of the nasal airway, such as septal deformities, nasal polyps, and choanal atresia and with certain mucosal conditions such as sinusitis, allergic rhinitis and inferior turbinate hypertrophy can cause snoring or OSA. Thus, these sources of nasal obstruction should be corrected medically or surgically for the effective management of OSA and adjunctive for CPAP.

2.Perinatal Hypoxic-lschemic Brain Injury: MR Findings.
Journal of the Korean Radiological Society 1994;31(3):405-410
PURPOSE: To characterize the MR findings of hypoxic-ischemic brain injury and to assess the value of the MR imaging. MATERIALS AND METHODS: SE T1 -, T2-weighted, and IR brain MR images of 44 infants and children with the past history of perinatal hypoxic insults were reviewed. Abnormal brain MR findings of 8 patients with birth history of prematurity and 36 patients with birth history of full-term/posterm including 7 with severe anoxic insult history, were compared in regard to the location and the character of the lesions RESULTS: MRI demonstrated the followings;(1)abnormal signal intensity lesions of subcortical and/or deep cerebral white matter, cortex, and deep gray matter, (2)atrophy of the cerebral white matter, cortex and corpus callosum, with/without ventriculomegaly, and (3)delay in myelination. Periventricular and deep white matter lesions were demonstrated in the prematurity, the deep white matter lesions and/or subcortical white matter lesions in the term/post-term, and deep gray matter lesions in the 7 patients with severe anoxic insults history. CONCLUSION: MR imaging was useful in the diagnosis of the hypoxic-ischemic brain injury, and the white and gray matter lesions were correlated with the time of the injury and the severity of hypoxic insult.

PURPOSE: The skeleton is commonly affected by metastatic cancer. The purpose of this study was to evaluate the results of treating metastatic pathologic fractures in lower extremities using locking plates. MATERIALS AND METHODS: Between 2004 and 2010, we evaluated 12 patients (13 cases) of metastatic pathologic fractures in lower extremities, treated with the locking plate. Mean patient age was 62.2 years (range, 50-81 years), the locations of the fractures were; proximal femur in 2 cases, femoral mid-shaft in 3, distal femur in 3, proximal tibia in 4, and distal tibia in 1 case. The interval to wheelchair ambulation, pain relief and complications were evaluated. Additionally, we assessed operation time and postoperative blood loss. RESULTS: Mean time from operation to wheelchair ambulation was 3.2 days (range, 1-6 days). Mean VAS scores improved from a preoperative score of 8.1 points (range, 7-9 points) to a score of 2.7 points (range, 2-4 points) at 1 week postoperatively. No early complications associated with surgery were encountered. Mean operation time was 88.4 minutes (range, 70-105 minutes), and mean postoperative blood loss was 246.5 ml (range, 130-320 ml). CONCLUSION: Internal fixation of metastatic pathologic fractures using a locking plate in the lower extremity can be an effective treatment option in the meta- or diaphyseal area of long bones with massive bony destruction or poor bone stock by offering early ambulation, pain relief and low postoperative complications.

5.Moyamoya Disease: Difference of MR Findings between Children and Adults.
Journal of the Korean Radiological Society 1995;33(6):979-985
PURPOSE: To evaluate whether there are any differences in MR findings between the childhood and the adult moyamoya disease. MATERIALS AND METHODS: We compared the brain MR findings in 22 children (13 boys and 9 girls, 2-18 years of age) who had moyamoya disease with 15 adult patients (7 men and 8 women, 19-55 years of age). The MR findings were classified as parenchymal-(infarctions and intracranial hemorrhages) and vascular abnormalities (intracranial vascular patency and moyamoya vessels). The difference in each of these MR findings was analyzed using Chi-squaretest and Fisher's exact test (two-tailed). Out of 22 children, two children with normal MR finding were excluded from the statistical analysis. Moyamoya diseases were diagnosed angiographically in all adult patients. In children, they were diagnosed by MR imaging, MR angiography(6), and/or conventional cerebral angiography(18). RESULTS: In children, cerebral infarctions were observed in 20 of 22 patients (91%) (cortex 86%, periventricular white matter/centrum semiovale 32%, basal ganglia 10%). In two patients, there was no parenchymal abnormality. Intra-cranial hemorrhages were not demonstrated in any patients. In adults, intra-cranial hemorrhages(intracerebral hematoma, intraventricular hemorrhage, alone or combined) were demonstrated in 10 of 15 patients(67%). Cerebral infarctions with or without intracranial hemorrhage were detected in 10 of 15 patients(67%)(cortex 40%, periventricular white matter/centrum semiovale 53%, basal ganglia 20%). The difference in parenchymal abnormalities between the childhood and the adult moyamoya disease was statistically significant (p=0. 000164). There was no significant difference between the two groups with regard to the occlusive changes of the internal carotid and middle cerebral arteries or to moyamoya vessels(p> 0.01 ). CONCLUSION: This study could prove the fact that the principal clinical symptoms in the childhood moyamoya disease were due to cerebral infarction and those in the adult cases were due to infarction and intracranial hemorrhage. In addition, cortical infarction was more prevalent in children and infarction in periventricular white matter/centrum semivoale and basal ganglia was more frequentin adults. There was no significant difference in vascular abnormalities between the two groups.

This survey was conducted from January 1991 to May 1991. Two hundred and eight residents in 4 government supported homes for the aged and hundred and eleven living in the community in Taegu, Korea, were examined to evaluate the depression and the anxiety of the aged with combined anxiety and depression scale (CADS) and somatization symptom check list (SCL). There are no significant differences between residents in the home for the aged and those living in the community on the total scores of CADS and SCL. However, in the case of the total score of CADS of the female subjects in the home for the aged were significantly higher than those of the community residents. The elderly in the home for the aged tended to have pure depression, while community residents were likely to have anxiety and depression. Fifty-two subjects of home for the aged and sixty-nine of the community scored over 50 points of CADS, which indicates considerable depression or anxiety. In psychosocial factors, the subjects who in the following situations had statistically significant higher scores than others. The results were as follow. Poor health, unhappiness, unsatisfaction to the past occupation, pessimistic thought in future view for both group and unsatisfaction of the relationship with familiar people for the elderly in the community. The SCL scores of two groups subgrouped by under 49 and 50 on CADS showed significant differences between each subgroup on all of the SCL items. It could be suggested that somatic symptoms for the aged is a sign of depression.

Korean Journal of Pathology 1986;20(3):305-312
The coronary arteries of young individuals are histologically studied. Fourteen cases in pediatric age group and three adult hearts were used. No case had clinical and pathological evidences of heart disease. Inner circumference, thickness of tunicae intima, media and adventitia were measured at eight different sites of coronary arteries. The thickness of tunica media was used as a standard scale of cardiac growth, and the heart weight, body weight, height and age were compared with the medial thickness. The morphological changes were assessed in five groups by the heart weights. Group I ( less than 10 gm) showed single endothelial lining with cytoplasmic vacuolization or endothelial denudation. Group II (more than 10 but less than 20 gm) consisted of full term babies and showed first stigma of focal intimal thickening and intimal collagen fibers. Diffuse intimal thickening more than 1/1 of medial thickness was first seen in a case with 46 gm of heart weight. Elastic fiber was not seen in internal elastic laminae of groups I and II. Fragmentation of internal elastic lamina and smooth muscle proliferation as a form of musculoelastic layer were the major findings of intimal thickening in childhood and no case showed complicated atherosclerotic lesions.
