We report a case of calcinosis cutis following administration of 10% calcium gluconate, used for the treatment of a hypocalcemic seizure in a 5-week-old neonate. After administration of 10% calcium gluconate, subcutaneous induration developed at the infusion site. The histopathological findings taken from the dorsum of the left foot showed multiple foci of calcium deposits with infiltration of epitheloid histiocytes between collagen bundles and foreign body giant cells phagocyting calcific granules throughout the reticular dermis and subcutis.

PURPOSE: With the process of neoangiogenesis being linked to the growth and metastasis of various tumors, anticancer therapeutics with a basis in the suppression of neoangiogenesis has recently been receiving attention. In this study, we tried to clarify the immunoreactivities of vascular endothelial growth factor (VEGF), major angiogenic inducer and thrombospondin-1 (TSP-1), major angiogenic inhibitor in human Wilms' tumor and its clinicopathological significance. MATERAILS AND METHODS: Utilizing immunohistochemical staining, we assessed the immunoreactivities of VEGF and TSP-1 in archival tissues of 29 Wilms' tumors and 25 normal kidneys. Also, we assessed the relationship between expression of each factor and clinicopathological parameters in 29 cases of Wilms' tumors. RESULTS: Immunoreactivities of VEGF and TSP-1 were detected mainly in the cytoplasm of the tubular cells in normal kidneys. In Wilms' tumors, whereas VEGF was detected in the cytoplasm of the tumor cells and peritumoral stromal tissues, but TSP-1 only in the peritumoral stromal tissues. Immunohistochemical expression patterns of each factor were divided into two groups according to the area of immunoreactivity (negative:<10%, positive: > OR =10%). VEGF immunoreactivity was detected in 25 (100%) normal kidneys and in 20 (69%) Wilms' tumors. However, TSP-1 immunoreactivity was detected in 24 (97%) normal kidneys and in 3 (10%) Wilms' tumors. Therefore, although no significant difference was observed between the expressions of VEGF and TSP-1 in normal kidney, the TSP-1 immunoreactivity was significantly lower than VEGF immunoreactivity in Wilms' tumors. A relatively higher rate of positive expression of TSP-1 was observed in the patients with no demonstrable lymph node metastasis. Also, as for the VEGF, maximal diameter of the tumor was larger in the positive expression group. However, it proved otherwise for TSP-1 as the negative expression group demonstrated tumors with larger maximal diameters. CONCLUSIONS: Our study demonstrated that the TSP-1 immunoreactivity was significantly lower than VEGF immunoreactivity in Wilms' tumors, and disease progression has a tendency to be found in the VEGF-positive cases and TSP-1 negative cases. We suggest that the growth and metastasis of Wilms' tumor may be influenced mainly by TSP-1 decrease rather than VEGF increase.

2 patients of forearm deformities with ulnar defect and radial head dislocation were treated with the Ilizarov apparatus at Chungnam University Hospital. One patient had a severe hypoplastic remnant-like ulnar fragment and a anterolaterally dislocated radial head due to complicated osteomyelitis of ulnar. We applied an Ilizarov apparatus to transport the radial head distally, and fixed to remaining proximal ulnar fragment. The other had a large bony defect at the ulnar shaft and a dislocated radial head due to complicated osteomyelitis of ulna. We performed internal transport of ulna to decreased the ulnar defect and to descend the dislocated radial head. The clinical-radiological features and functional results of those 2 forearm deformities were described with brief review of the articles about the Ilizarov method for correction of forearm defor- mities.

The incidence of conjoined twins is so rare that few anesthesiologists have an opportunity of managing them. Especially in Korea, there are only a few reports describing the anesthetic management for surgical separation of newborn conjoined twins. We experienced the successful anesthetic management for surgical separation of thoraco-xiphopagus conjoined twins without any particular problems. After applying the noninvasive monitors (ECG, pulse oximeter), one of the twins (twinA) with congenital heart disease was administered with intravenous ketamine for induction of anesthesia and intubated without neuromuscular blocker. Anesthesia was maintained with N2O-O2 and hand ventilation using Mapleson D breathing circuit. After maintaining airway of the twinA, the twinB was intubated and maintained with the same manner. Eighteen days after the separation procedure, the twinA with congenital heart disease died and the other one, twinB has been alive with normal growth and development.

PURPOSE: In patient with blunt trauma of chest, supine AP x-ray cannot differenciate the lung contusion, laceration, atelectasis, and hemothorax definitely. Therefore, computed tomographic evaluation is needed for accurate evaluation of the injuries. In our knowledge, there are few reports about CT findings of blunt chest trauma, in our country, therefore we tried to fiud the characteristic CT findings in patients with blunt trauma. MATERIALS AND METHODS: We analyzed the plain x-ray and CT image of 4 patient with blunt chest trauma. Location and morphology of lung parenchymal contusion and laceration, hemopneumothorax, chest wall injuries and location of chest tube. RESULTS: Lung parenchymal contusion was noted in 53 segments. of 16 patiants'infiltration(n=27 segment), and multiple nodular pattern was noted in 15 segment, pattern of consolidation along the lung periphery was seen in 11 segment. Laceration was noted in 18 lesion and most commonly located in paravertebral area(b=8). CONCLUSION: CT scan of chest in patient with blunt chest trauma, provides accurate informations of the pattern of injuries, and localization, therefore, should be performed as po9ssible.

BACKGROUND: Inguinal hernia is one of the most common surgical diseases in pediatric patients. We reviewed pediatric inguinal hernia cases retrospectively to analyze the clinical characteristics. METHODS: We reviewed 200 herniorrhaphies in 194 patients who were under the age of 15 and who were operated on at Chungbuk National University Hospital from January 1992 to July 1997. RESULTS: 1) All of the cases were indirect inguinal hernias. Sliding hernias were noticed in 6 cases. High ligations were performed in all cases except 2 cases of Bassini operations. 2) Boys were affected 3.4 times more often than girls. 56.2% of the hernias occurred on the right side, 35.0% on the left side, and 8.8% bilaterally. Bilateral inguinal hernias occurred more often in girls (13.6%) than in boys (7.3%). 3) Hernias were noticed under the age of 1 year (47.9% of the cases). In most of those cases, operations were delayed. Especially, the operations were delayed more than 3 months for 82.1% of patients with hernias and under the age of 6 months. 4) On admission, most patients complained of inguinal or scrotal swelling and inguinal pain or discomfort. 5) Hospitalization occurred in 20.6% of the cases, 3 of which needed emergency operations. Hospitalization occurred in 47.5% of the cases under the age of 1 year; in those cases, hernias were noticed within the first 6 months, and in most of those cases, operations were delayed more than 3 months. 6) Postoperative complications occurred in 9 cases, i.e., 8 cases of scrotal swelling and 1 case of scrotal hematoma. There were no recurrent cases after operation (average follow-up of 33 months). 7) After unilateral inguinal hernia repairs, contralateral hernias developed in 10 patients including 4 patients who had had received their first hernia operations at other hospitals. The sex ratio was 9:1. Laterality of the first hernias were right in 5 cases and left in 5 cases. Contralateral hernias developed within an average of 4.8 months after the first operation; however, 6 cases developed within 6 months after the first operation. CONCLUSIONS: Education for early operation to prevent complications of hernias and careful evaluation of contralateral inguinal hernias in unilateral hernias are needed in the treatment of pediatric inguinal hernias.
