Paralytic scoliosis is a disease characterized by its long severe curve and the continuous progression of the deformity even after cessation of growth. It is also resistent to conservative treatment and more patients require surgical treatment than those with idiopathic or congenital curvature. Patients suffer from marked limitation of normal activities in walking and sitting due to imbalanced paralysis of trunk muscles and pelvic obliquity. The indication for the conservative treatment with Milwaukee brace allowing for skeletal growth in a straight alignment is much limited and surgical correction and fusion are almost always indicated even in a young age. This paper was aimed to review our experience with ninteen patients with paralytic scoliosis who were treated with various methods of preoperative corrections and surgery from Jan. 1970 to Dec. 1981 and the following results were obtained. 1. The average age when scoliosis was observed was 7.7 years but the average age of surgery was deferred to 17.7 years. 2. No treatment had been done until most of the patients could no longer maintain balanced posture in sitting and walking due to collapsing spine and marked pelvic obliquity. 3. The causes of paralysis were poliomyelitis in 15 cases, meningocele in two, cerebral palsy and Charcots disease in each one. 4. Preoperative average degree of scoliosis was 107.8° and the final correction was 47.9°(44.4%) with loss of correction 3.6° (3.4%) after 5.6 years of follow-up in average. 5. The more severe the curve was, the more flail was the spine and the more correction could be obtained. 6. Preoperative correction was performed for 16 cases and Harrington instrumentation and posterior fusion were performed for all cases except one meningocele with defect of posterior element in which Dwyer instrumentation was indicated. 7. Breakage of Harrington rod was observed in two cases 1.3 and 3.8 years postoperatively but no problem arose from it in seven and two years of follow-up respectively. 8. Significant pelvic obliquity was observed in seven cases, which were treated by Harrington instrumentation with sacral bar or sacral hook and posterior fusion extended to sacrum.

We report herein three cases of vesicular pemphigoid that is a varient of bullous pemphigoid, occuring in 38-year old female, 51-year old male, and 35-year old female patients. They had recurrent and moderate to severe pruritic tense vesicles with symmetrical distribution chiefly on the head and neck areas. The histological findings showed subepidermal bullae which contained a few eosinophils and the direct irnmunofluorescent tests revealed linear deposition of IgG, IgM and C, on the basement mernbrane zone. Futhermore, all the patients showed a good response to dapsone.

OBJECTIVES: The aim of this study was to evaluate the differences in patients with positional dependent sleep apnea according to their non-supine apnea-hypopnea index (AHI, > or =5 vs. <5). METHODS: 92 patients with positional sleep apnea were evaluated. The patients were divided into two groups : group I was non-supine AHI having > or =5 ; group II was non-supine AHI having less than 5. Statistical analysis was performed to find the difference between two groups. RESULTS: In 92 patients, the number of group I patients was 11 (12%) and the number of group II patients was 81 (88%). In the severe AHI group, percentage of group I was dominated (70%) and showing a significant difference compared with the mild and moderate AHI groups (p<.05). In the severe body mass index (BMI) group, percentage of group I was dominated (54.5%) and showing a significant difference compared with of the mild and moderate BMI groups (p<.05). The percentage of group I was significantly higher than group II (p<.05) in the AHI, supine AHI, non-supine AHI and snore time. CONCLUSIONS: In patients with positional sleep apnea, severe OSA and high BMI are more common in patients with non-supine AHI> or =5 than non-supine AHI<5.

STUDY DESIGN: A retrospective analysis of 166 patients was undertaken to observe radiologically the changes of adjacent segments at follow-up more than three years after lumbar fusion. OBJECTIVES: The purpose of this study is to analyse the changes of adjacent segments and to correlate these changes to the length of using level and to the degree of deviation from physiologic lumbar lordosis. The authors also correlate these radiologic changes to the clinical symptoms. MATERIALS AND METHODS: In simple x-ray, authors observed traction spur, disc space narrowing, endplate sclerosis and vacuum phenomenon of adjacent segments. Authors used Gelb's criteria in segmental lordosis angle(SLA) and Katz's classification in clinical results. RESULTS: The average age was 49.6 years old and the average follow-up period was 57.2 months(4 years and 9.2 months). We observed radiologically the traction spurs in 35 cases(21.1%), end-plate sclerosis in 32 cases(19.3%), disc space narrowing in 33 cases(19.9%) and the vacuum phenomenon in 10 cases(6.0%). The numbers of fusion segments and the degree of unphysiologic segmental lordosis angle in fusion segments were related with the frequency and degree of changes of adjacent segments(P<0.05). The clinical results showed satisfaction in 142 cases(85.5%), unsatisfaction in 24 cases(14.5%) and low back pain in 24 cases(14.5%), leg pain in 11 cases(6.6%) and extension of fusion level in 4 cases(2.4%). In low back pain patients more than two kinds of radiological changes were frequently observed than the patients without low back pain(P<0.05). CONCLUSIONS: The radiological changes of adjacent segments were more frequently observed in long fusion and in fusion with unphysiologic lumbar lordosis angle. And these changes are frequently associated with low back pain. Thus long fusion and fusion with unphysiologic lumbar lordosis angle should be avoided if possible.

This clinical and histopathological study was performed with 147 cases of benign mielanocytic tumors and 19 cases of malignant melanomas, which were obtained as surgical specimens from 1974 to 1984 at Department of Clinical Pathology, Catholic Medical College. The results were as follows: 1, In 89 cases of acquired benign melanocytic nevi, the average age of intradermal type(64 cases) was 34. 7 years and that of compound type(24 cases) was 24. 6 years. 2. In 30 cases of congenital nevus, nevus cells were present in the lower two thirds of reticular layer of the dermis in 93. 3% and in the subcutis as well in 3.3%. A case of giant congenital nevus with balloon cell appearance was found. 3. Of the 147 benign melanocytic tumors, a pigmented spindle cell nevus and a desmoplastic nevus were observed. 4. Blue nevi were 11 in number and excised from the face in 7, buttock in 2, shoulder in 1, upper arm in 1, and all were common type histopathologically. 5. Twelve malignant melanornas which were possible to be re-examined histopathologically were composed of 5 nodular type, 3 acral lentiginous type, 1 superficial spreading type and 3 metastatic malignant melanoma.

We obtained sixty normal chest postero-anterior(PA) radiographs with high kilovoltage technique(90-110kVp), 10 radiographs from the consecutive normal persons in each decade from twenties to seventies to analyze normal course and appearance of azygoesophageal recess (AER) line. (AER) line. CT scans from sixty consecutive normal persons were correlated with the radiographs to see how the line is formed and what structure the line abuts. In 20 patients with a lesion in AER area(10 with subcarinal lymphadenopathy of various size, five with left atrial enlargement, three with lesions in the esophagus, and two with dilated azygos vein), radiographic and CT correlation was done with main attention to the pattern of displacement of the azygoesophageal line. In normal chest PA radiographs, AER was shown as a straight line in young adults. As age increased, it was seen as a smooth are with convexity to the left. Sigmoid shape with midline cross was noted in an aged person. At the level of the right main bronchus on CT, AER was noted along the right lateral aspect to the vertebral margin in young adults. It extended medially as age increased. Caudally the recess extended more medially. The azygos vein usually bordered the recess. The esophagus or mediastinal fat sometimes bordered the recess in caudal level. In normal persons, the recess appeared deeper on plain radiographs than on CT. On plain radiographs, there were no changes in contour of AER with subcarinal lymphadenopathy of less than 2.5cm in diameter. However right sided and downward displacement of AER line just below the carina was noted with lymphadenopathy of more than 2.5cm in diameter. With left atrial enlargement, obliteration of the line was noted at T8-10 level. Focal right sided bulging of the line was noted with esophageal cancer Dilatation of azygos vein caused the line to appear with right sided displacement. In conclusion, AER line can be delineated with various features on radiographs with high KVP technique, depending on the age of normal persons and the formation of the line can be explained with CT. Displacement and change in the contour of the line can be seen with various mediastinal diseases.
