We experienced a case of acquired bronchial stenosis in a male premature infant who had recurrent postextubation atelectasis of the right lung. Bronchography showed the stenosis of the distal portion of right main bronchus and the proximal portion of intermediate bronchus and autopsy findings showed ill-defined irregularly elevated nodule with fibrotic scarring in the trifurcation of right main bronchus. Endotracheal suction was suspected as the main cause. A brief review of literature was made.

The widespread use of diagnostic radiography, especially using magnetic resonance imaging, has helped to increase the diagnosis of paralabral cysts in patients with chronic shoulder pain. These paralabral cysts are frequent in the anterior, the superior, and the posterior compartment of the shoulder joint but are rare in the inferior compartment. Paralabral cysts in the shoulder appear particularly in men in their third and fourth decades but rarely in elderly patients. We report a case of an inferior paralabral cyst in an elderly patient whom we treated through arthroscopic decompression.

Congenital scoliosis is defined as a lateral curvature of the spine caused by congenital anomalies of the vertebral development. In this study seventeen congenital scoliosis patients seen and treated by either Milwaukee brace or surgical intervention at Department of Orthopedic Surgery, Seoul National University Hospital from December 1972 to April 1978 were evaluated according to frequency of the curve pattern, character of the deformity, method of treatment and its correctability. The following results were obtained in this study. 1. Age distribution was from 2 to 39 years and mean age was 13.4 years. 2. The most common deformity pattern was hemivertebra in 8 cases (47.1%), unilateral unsegmented bar in 4 (23.6%) and mixed type in 3 (17.6%). 3. The most common curve level was thoracic in 6 cases (35.3%), followed by thoracolumbar in 4 (23.5%) and lumbar in 4 (23.5%). 4. The best corrected type by Milwaukee brace was trapezoid vertebra (29.4%) and then mixed type(26.1%), followed by block type (20%) and hemivertebra(2.3%). 5. The operative treatment was performed in the cases of unilateral bar and progressive type with Milwaukee brace. In terms of the correctability of the curvature, the surgical intervention was better than the conservative treatment, with the result of its average correction of 33.5% that is compared with 15.9% of Milwaukee brace. 6. Halofemoral traction was effectively applied in the cases of rigid and severe curve; the initial curve 76.3 degress with 21.3% of flexibility. 7. Loss of correction in operative treatment was 2.3 degrees (6.5%).

In 1868 Charcot described the join in tabes dorsalis, which since then has been designated as Charcot neuroarthropathy. It is characterized by painless swelling and abnormal mobility of the affected joint. Arthropathy of the type described by Charcot has been associated with various other conditions, such as diabetes mellitus, syringomyelia, injury to nerve root, congenital indfference to pain, leprosy, and intra-articular use of steroid, etc. Authors present a case of Charcot joint which involved the left knee joint associated with pathologic fracture of the left tibia and fibula.

To evaluate the efficacy and safety of Excimer Laser Photorefractive Keratectomy (PRK) on the correction of high myopia, we performed planned double-pass PRK procedure at the same session on 62 eyes of 55 patients with myopia ranging from -6.30D to -15.25D (mean, -9.94D). In the first pass, a myopic correction of -6.00D with a 4.5 millimeter ablation zone was performed, and immediately after, a second correction of remaining myopia with a 5.0 millimeter ablation zone was performed. Attempted correction ranged from -6.30D to -9.50D (mean, -8.70D). The eyes were divided into two groups which were -10.50D or less (group A), and higher than -10.50D (group B). All the eyes received topical corticosteroid therapy postoperatively. One year after double-pass PRK, uncorrected visual acuity in group A and B improved to 20/40 or better in 84.0%, and 73.3% of the eyes and to 20/30 or better in 75.0% and 33.3% of the eyes respectively. The mean refractive errors at 12 months after PRK were -0.3 +/- 1.6D in group A, and -1.5 +/- 2.1D in group B. The percent of achieved correction within +/- 1.0D were 70.8% in group A, and 46.7% in group B 12 months after surgery. The epithelium healed by three days and there were no corneal erosions. Corneal haze (Grade 2 or more) was seen in 9.0% in group A and 36.4% in group B at 12 months after PRK. A planned double-pass PRK is a promising approach to correct high myopia (up to -10.50D), but long-term follow up will be required.

We had replaced 159 hips in 130 patients with cementless porous-coated AML porsthesis at Kwang Ju Christian Hospital between April 1987 and Feb. 1992. Among them, 100 cases(80 patients) could be analyzed clinically and radiologically with an average follow-up of 38.5 months(range 10 months to 74 months). The purpose of this study was to evaluate the relationships of initial fit, follow up stability and clinical results. The results were as follows. 1. The average postoperative Harris hip score was 90 points(preop. 42) at the follow-up of 1 year or more, the pain score 41 points(preop. 15). 2. When the surgical fit of stem was achieved properly, fixation by bone ingrowth could be expected. Simultaneously adequate fit of acetabular cup provided stable fixation. 3. The incidence of thigh pain was high in patients with an unstable implant of stem and the hip pain was more common in group of a definitely unstable cup. 4. Stress shielding was seen in 44 cases(44%). Of the 44 cases, 38 cases(86%) revealed in bone ingrowth. In conclusion, this study showed good clinical result of THR using AML prosthesis at the average follow-up of 38.5 months and it seemed to be influenced by initial fit significantly. But long-term follow-up is needed for accurate clinical and radiological evaluation.

Surgical treatment of congenital scoliosis is often frustrating due to its severity and rigidity. Many surgical methods were provided for these complex deformities and some instruments were used to achieve better correction. However, no surgical treatment was satisfactory to correct the deformities. Recently, pedicle screw fixation, enabling a powerful grip of individual vertebral segment, is becoming a promising method to enhance correction of these tenacious deformities. This study was to compare the correction, loss of correction and complications of the various surgical methods employed for congenital scoliosis in Seoul National University Hospital and to verify the advantages of pedicle screw fixation. Ninety-two congenital scoliosis subjected to surgery and followed up for more than 2 years(range 2-9 years) were analysed. Surgical methods were; anterior uninstrumented fusion, 5; posterior fusion, 50(14 without instrument, 15 with hooks, 21 with screws); combined anterior and posterior fusion, 37(7 without instrument, 11 with posterior hooks, 10 with posterior screws, 9 with anterior VDS and posterior screws). Mean preoperative magnitude of index curve was 58° with no significant difference between the groups except for the anterior VDS and posterior screw group which had a mean magnitude of 93°. Mean flexibility of index curve was 18.7% with no significant difference between groups. The correction of index curves were; anterior uninstrumented fusion, 23%; posterior uninstrumented fusion, 28%; posterior hook, 31%; posterior screw, 46%; combined anterior and posterior uninstrumented, 37%; anterior fusion and posterior hook, 30%; anterior fusion and posterior screw, 47%; anterior VDS and posterior screw, 48%. The correction of pedicle screws were significantly better(p < 0.01) with significantly smaller loss of correction(p < 0.01). Nonunion occurred in 4, 1 in posterior uninstrumented fusion, 2 in posterior hooks and 1 in posterior pedicle screws with concomitant instrument failures. However, there were no neurologic or visceral complications related to screw placement. Pedicle screw fixation offers an enhances correction of congenital scoliosis with low complication rate, and when combined with an anterior procedure, enables control of the most severe and rigid curves.

Although liver function test abnormality is frequently noted in children, there is no report about the distribution of the etiology and natural recovery time of the abnormal liver function. From March 2005 to February 2014, clinical information was retrospectively collected from 559 children who had abnormal liver function and were hospitalized or visited the outpatient clinic at the Jeju National University Hospital. The etiology of abnormal liver function was classified into groups and the natural recovery time of abnormal liver function was analyzed. The etiological groups of 559 patients included 'nonspecific hepatitis' in 42 (7.5%), 'infection' in 323 (57.8%), 'rheumatologic and autoimmune' in 66 (11.8%), 'nonalcoholic fatty liver disease' in 57 (10.2%), 'anatomic' in 12 (2.1%), 'toxic' in 13 (2.1%), 'metabolic' in 8 (1.4%), 'hematologic' in 7 (1.3%), 'hemodynamic' in 4 (0.7%), and 'others' in 27 (4.8%). Among the 'infection' group (57.8%), the 'viral infection in the respiratory tract' subgroup, which had 111 patients (19.8%), was the most common. The natural recovery time of the abnormal liver function was 27 days (median) in 'nonspecific hepatitis', 13 days (median) in 'viral respiratory tract disease', 16 days (median) in 'viral gastroenteritis', 42 days (median) in 'viral febrile illness", and 7 days (median) in "Kawasaki disease". The information on the natural recovery time of abnormal liver function may help the physician to perform good clinical consultation for patients and their parents.

Rotator cuff tear is a common musculoskeletal disease that often requires surgical repair. Despite of recent advances in surgical techniques, the re-tear rate of the rotator cuff tendon is very high. In this study, a platelet-derived growth factor-BB (PDGF-BB)-immobilized asymmetrically porous membrane was fabricated to investigate the feasibility for enhancing rotator cuff tendon regeneration through the membrane. PDGF-BB is recognized to promote tendon regeneration. The asymmetrically porous membrane was fabricated by polycaprolactone and Pluronic F127 using an immersion precipitation technique, which can allow selective permeability (preventing scar tissue invasion into defect region but allowing permeation of oxygen/nutrients) and incorporation of bioactive molecules (e.g., PDGF-BB) via heparin binding. The PDGF-BB immobilized on the membrane was released in a sustained manner over 42 days. In an animal study using Sprague-Dawley rats, the PDGF-BB-immobilized membrane group showed significantly greater regeneration of rotator cuff tendon in histological and biomechanical analyses compared with the groups of control (suturing) and membrane without PDGF-BB immobilization. The enhancing regeneration of rotator cuff tendon of the PDGF-BB-immobilized membrane may be caused from the synergistic effect of the asymmetrically porous membrane with unique properties (selective permeability and hydrophilicity) as a scaffold for guided tendon regeneration and PDGF-BB sustainedly released from the membrane.
