We reviewed 23 patients of injury to the spine who were under 15 years of age and treated at Wonju Christian Hospital from January, 1978 to December, 1987. The patients were classified into 3 different categories, that were frsctures(17 cases), dislocations(3cases), and fracture-dislocation(3 cases). We analyzed the cause of injury, sexage distribution, treatment and neurological injuries. The results were as follows : l. Among the 23 cases, there were 16 boys(70%) and 7 girls(30%). The mean age was 11 years of age, and ages of active period, that is 10 to 15 years of age, were most common, 17 cases(74%). 2. The most common cause of injury was fall from a height, 13 cases(57%). The most common location of injury was cervicsl spine, 10 cases(43%) and among these cases, injury to upper cervical portion(C1–C3) was more common than lower cervical portion(C4–C7). 3. The cases of multiple compression fracture were 6 patients(26%), and all cases were located thoracic or thoraclumbar junction. 4. Most cases were stable spinal injury, 18 cases(78%), and the most common mechanism of injury were compreesion injuries due to hyperflexion, 15 cases(65%). 5. The most common associated injury was head injury, 9 cases(39%), and associated neurological complications were in 4 cases, 3 cases of these were recovered. We could ascertain that the prognosis of children spinal cord injury is better than that of adult. 6. Restoration of the height of the involved vertebral bocy occurred in all but one compression fractures of vertebral body. 7. There were 3 cases of epiphyseal injury, 2 of these were epiphyseal separations of odotoid process of atlas, the other was fracture of lumbar vertebral apphysis. 8. All but two were treated conservatively and the results were good. In stable spinal injury, we considerded that the duration of treatment was 4 to 6 weeks.

Congenital adrenal hyperplasia is inherited disorder of adrenal steroidogenesis. 21-hydroxylase deficiency is the most commone enzymatic defect and is divided into classic and late-onset or nonclassic forms. Both classic non-classic 21-hydrozylase deficiencies are inherited in a recessive manner as allelic variants. But it is rare that happened in twin infants. Chief complaints of affected twins in our case were ambiguous genitalia, hyperpigmentation and dehydrations. They were revealed into hyponatremia, hyperkalemia and increased amount of serum progesterone, 17-hydroxyprogesterone and urinary 17-ketosteroid excretion and were administered with DOCA, 9alpha-fluorohydrocortisone, hydrocortisone to control the electrolyte imbalance. And now, both of them are going to normal ratio of weight gain and body growth.

The chondrogenic potential of free autogenous periosteal grafts for osteochondral defects was investigated at the Department of Orthopaedic Surgery, Yonsei University, Wonju College of Medicine. Five millimeter diameter of circular full-thickness defects were made in patellar groove of both femur in 64 adolescent rabbits and the rectangular periostei, prepared from the proximal tibiae, were placed over the defects of patellar groove and sutured(cambium layer, facing joint surface) and the rabbits were allowed to move actively. A serial gross and histologic examinations of neochondrogenesis were done during 8 weeks. The results were as follows. l. At 2 weeks after operation, neochondrogenesis was hardly seen either in the graft group or in the control group. The defects were partially filled with some fibrous tissue. 2. After 6 weeks of operation, all defects in the graft group(postop 6 weeks and 8 weeks) were filled with hyaline cartilage cells but only 38% (postop 6 weeks) and 44% (postop 8 weeks) of the control group were filled with hyaline cartilage cells. 3. The cartilages, formed at 6 and 8 weeks, were more mature and better than those formed at 4 weeks. 4. The newly formed hyaline cartilage of the graft group filled the defect earlier and were better than those of the control group. 5. The chondrocytes in the newly formed tissue were originated from the cambium layer of periosteal grafts. 6. Free autogenous periosteal grafts can repair a full-thickness defect in a joint surface by producing tissue that resembles articular cartilage grossly and histologically.

BACKGROUND: The risk of bleeding during extracorporeal membrane oxygenation (ECMO) is a potential deterrent in performing tracheostomy at many centers. To evaluate the safety of surgical tracheostomy (ST) in critically ill patients supported by ECMO, we reviewed the clinical correlation between preoperative coagulation status and bleeding complication-related ST during ECMO. METHODS: From April 1, 2012 to March 31, 2016, ST was performed on 38 patients supported by ECMO. We retrospectively reviewed and analyzed the medical records including complications related to ST. RESULTS: Heparin was administered to 23 patients (60.5%) for anticoagulation during ECMO, but 15 patients (39.5%) underwent ECMO without anticoagulation. Of the 23 patients administered anticoagulation therapy, heparin infusion was briefly paused in 13 prior to ST. The median platelet count, international normalized ratio, and activated partial thromboplastin time before ST were 126 ×109/L (range, 46 to 434 ×109/L), 1.2 (range, 1 to 2.3) and 62 seconds (27 to 114.2 seconds), respectively. No peri-procedural clotting complications related to ECMO were observed. Two patients (5.3%) suffering from ST-related major bleeding required surgical hemostasis. Minor bleeding after ST occurred in two cases (5.3%). No significant difference was found according to anticoagulation management (P = 0.723). No fatality was attributable to ST. CONCLUSIONS: The complication rates of ST in the patients supported by ECMO were low. Therefore, ST performed by an experienced operator, and with careful optimization of coagulation status, is a relatively safe procedure; the use of ST with ECMO should thus not be dismissed on account of the potential for bleeding caused by the administration of anticoagulants.

PURPOSE: To compare the effect of breast milk containing fortifier with preterm formula on bone mineral metabolism in premature infants, we evaluated the state of bone mineralization, biochemical alteration and the frequency of rickets during the first five months of life. METHODS: Fourteen fortified breast milk-fed infants and eleven preterm formula-fed infants who were born at Il-Sin Christian Hospital from August, 1996 through July, 1997, were studied. The breast milk-fed group received human milk fortifier. The intake of Ca, P, Mg, protein, and fat was calculated at one month of age. Birth weight and weight at one, two and five months of age were measured. Serum Ca, P, alkaline phosphatase and 25-hydroxyvitamine D were measured at one month of age, and the wrist received X-ray examinations monthly. Total body bone mineral content was measured by Dual energy X-ray absorptiometry (Lunar WI) at two and five months of age. RESULTS: The two groups were similar in birth weight, gestational age, and weight at one, two and five months of age. Enteral Ca, P, protein, Mg, and fat intake, and urinary excretion of Ca, P were similar among the two groups. Serum Ca, P, ALP and 25-hydroxyvitamin D were not different. Occurrence of rickets and bone mineral content were similar among the two groups. CONCLUSION: Fortified breast milk-fed infants and preterm formula-fed infants showed no difference in total body bone mineral content and occurrence of rickets. Ultimately, we could enhance the advantage of breast milk fed to premature infants by adding fortifier.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) strategy is proposed to reduce the ventilator-induced lung injury in acute respiratory distress syndrome (ARDS). As ECMO use has increased, a number of studies on prognostic factors have been published. Age is estimated to be an important prognostic factor. However, clinical evidences about ECMO use in elderly patients are limited. Therefore, we investigated clinical courses and outcomes of ECMO in elderly patients with ARDS. METHODS: We reviewed medical records of patients with severe ARDS who required ECMO support. Study patients were classified into an elderly group (> or = 65 years) and a non-elderly group (< 65 years). Baseline characteristics, ECMO related outcomes and associated factors were retrospectively analyzed according to group. RESULTS: From February 2011 to June 2013, a total of 31 patients with severe ARDS were treated with ECMO. Overall, 14 (45.2%) were weaned from ECMO, 9 (29.0%) survived to the general ward and 7 (22.6%) survived to discharge. Among the 18 elderly group patients, 7 (38.9%) were weaned from ECMO, 4 (22.2%) were survived to the general ward and 2 (11.1%) were survived to discharge. Overall intensive care unit survival was inversely correlated with concomitant acute kidney injury or septic shock. CONCLUSIONS: In this study, ECMO outcome was poor in severe ARDS patients aged over 65 years. Therefore, the routine use of ECMO in elderly patients with severe ARDS is not warranted except in highly selective cases.

PURPOSE: This study is to analyze the prevalence of various intra-articular lesions in patients with traumatic recurrent anterior dislocation of shoulder over 40 years and suggest clinical implications for treatment. MATERIALS AND METHODS: We retrospectively studied 16 cases that underwent surgical treatment for recurrent anterior dislocation of shoulder from January 2001 to May 2009. There were 9 males and 7 females, and the mean age was 52.7years. We carried out arthroscopic exam for all patients based on standard protocol, which included labrum, capular lesion, cuff, bony lesions. RESULTS: All 16 cases showed Hill-Sachs lesion, 3 patients (19%) had bony Bankart lesion, 6 patients (38%) had labral tear. Capsular tear were found 15 patients (94%). Twelve (75%) had ruptured supraspinatus and 5 (31%) had subscapularis tear. Only one (6%) had SLAP lesion. CONCLUSION: There was relatively higher incidence of capsular and rotator cuff tears in patients over age 40 years. Preoperative planning to address these lesions is highly recommended.

Goodpasture's syndrome (GS) is characterized by lung hemorrhage and glomerulonephritis and caused by autoimmune reaction between anti-glomerular basement membrane (GBM) autoantibodies and the alpha 3 (type IV) collagen chain. Some reports suggested that patients with anti-GBM autoantibody could be related with other autoimmune diseases including Graves' disease. We report a case of 14-year-old girl with Graves' disease treated with PTU for 4 years, who was admitted because of hemoptysis and dyspnea. Laboratory values included a serum creatinine value of 0.7 mg/dL, BUN 22 mg/dL, hemoglobin 3.9 g/mm3 and albumin 3.2 mg/dL. The thyroid function tests showed normal serum T3 and free T4, suppressed TSH, and elevated thyroglobulin Ab and TSH-R-Ab levels. Urinalysis showed 2+ for protein and many dysmorphic RBC/HPF. Both anti-GBM Ab and pANCA were positive serologically. In renal biopsy, the glomeruli showed mesangial proliferation and crescent formation with linear deposits of IgG along the GBM. This case is to represent the GS of patient with Graves' disease referring to medical documents.

PURPOSE: to investigate the effect of amniotic membrane transplantation (AMT) on corneal epithelial healing. METHODS: A 4-mm epithelial debridement was made in central rabbit cornea. Then, human amniotic membrane was transplanted (AMT group) or a contact lens was applied (contact lens group). The contralateral eyes were unwounded as controls. After surgery 5-bromo-2'-deoxyuridine (BrdU) was injected via ear vein. Each corneal tissue including the limbus was obtained on postoperative 12, 24 and 48 hours. Proliferating cell nuclear antigen (PCNA) in limbal and peripheral corneal epithelium and keratinocyte growth factor (KGF) in limbal stroma were immunolocalized by immunohistochemical method. Incorporation of BrdU in limbal and peripheral corneal epithelium was visualized by indirect immunofluorescent method. RESULTS: AMT group significantly accelerated the expression of PCNA and BrdU at limbal and peripheral corneal epithelial cells. The expression of PCNA and BrdU showed a peak at 24hr in both groups and increased in limbal epithelial cells more than peripheral corneal epithelial cell in AMT group. The expression of KGF on limbal keratocyte increased in AMT group more than contact lens group and coincided wiht the expression pattern of PCNA and BrdU. The number of keratocyte in significantly decreased in contanct lens group compared wiht AMT group. CONCLUSION: AMT enhanced corneal epithelial wound healing in vivo by stimulating limbal epithelial proliferation which is indirectly mediated in part by upregulating the expression of KGF, which is a potent epithelial mitogen secreted by limbal keratocytes.
