Supracondylar fracfture of the humerus is the most common fracture about the elbow joint in children. Early accurate reduction is very important to obtain good results. The authors reviewed 44 cases of supracondylar fractures treated at Inje Universsity Pusan Paik Hospital from January 1986 to December 1990. Average follow-up time was 1 year 6 months. The results were as follows; 1. Thirty cases were treated with closed reduction and percutaneous pinning, ten with manipulation and cast immobilization, three with skeletal traction and the rest one with open reduction and internal fixation. 2. If there was a difference of the angle within 10-degree in post-reduction X-ray, deformity did not follow at the last follow-up. 3. The common formula was that a change of 5-degree in Baumann's angle corresponded to a 2- degree change in the clinical carrying angle. 4. Baumann's angle did not change between that of initially accepted and that of the final follow up X-ray. So, the authors recommend post-reduction measurements of the Baumann's angle as the adequancy of reduction of supracondylar fractures in children.

Bone defect of the long bone continues to challenge orthopedic surgeons. It is usually very difficult to obtain union. Ilizarov ext. fixation has recently gained popularity as a multifactorial approach to the management of tibial bone defect because nonunion, bone defects, limb shortening, and deformity can all be addressed simultaneously with the Ilizarov apparatus. From February 1992 to May 1993 at the department of orthopedic surgery, Inje University Pusan Paik Hospital, 9 patients aged from 8 to 37 years were treated for tibial bone defect. The causes were open comminuted fractures with initial bone loss and bone defect after removal of infected necrotic bone. Bony defect size was ranged from 2cm to 14cm, averaging 7.2cm. Bony defects were gradually closed by the Ilizarov's internal bone transport technique, and final equalization of leg length discrepancy was achieved by means of external lengthening technique. Soft tissue defects were treated with secondary closure, split thickness skin graft, and muscle flap. The average healing index was 42.8 days/cm. According to Paley's classification the complications were developed as follows; The problem included pin tract infection(9), knee flexion contracture(4), and intractable pain(1), the obstacles included delayed union(3) and premature consolidation(1), the complication included nonunion(9) and equinus ankle(1). At an average 1 years follow up, according to Paley and Catagnl's classification, body and functional results were either excellent or good in 7 cases. So, we recommend that Ilizarov technique is very useful treatment for open fracture with bone loss, bone defect after removal of infected necrotic bone and limb shortening.

Aniskiasis is caused by the accidental infestation of human by larvae of marine mammals found in saltwater fish and squid. The clinical picture may be severe enough to stimulate an acute surgical abdomen. More commonly, colicky pain, diffuse abdominal tenderness, nausea, vomiting, fever, and leukocytosis are seen. Gastroscopically, 2-to 4-cm larvae can be seen penetrating the mucosa. More characteristically, the larvae burrow into the mucosa of the stomach. Here they produce eosinophilic granulomatous tumors with edema, thickening, and induration which may be mistaken for gastric canceer. The pathalogic changes are thought to be the result of a hypersensitivity reaction. We report a case of chronic gastric anisakiasis, which was diagnosed as submucosal tumor with massive bleeding.

Gastric metastasis occurs in about 0.7% to 1.7%, of patients dying of solid tumors of extragastrointestinal origin. Metastatic disease involving the stomach is an unusual and difficult clinical problem and presenting symptoms include nonspecific epigastric pain and melena. In most cases of gastric metastasis, the histologic finding of the gastroscopic biopsy suggests the correct diagnosis. There are only a few reports of gastric metastasis from malignant melanoma. We report a case of malignat melanoma of gastric metastasis, which was diagnosed by gastroscopy.

Cis-AB and B(A) alleles encode an ABO enzyme with dual A and B glycosyltransferase activity. Although globally rare, the cis-AB phenotype is found relatively often in Korean, Japanese, and Chinese populations. Cases of the B(A) allele have been reported mostly in the Chinese population. Forward typing performed in a Cambodian woman with an ABO discrepancy demonstrated a strong reaction with anti-A and anti-B reagents, while there was no reaction with lectin anti-A 1. The anti-A 1 antibody was detected in reverse typing. Through ABO gene sequence analyses of exons 6 and 7, one of the alleles was identified as ABO*B.01. In contrast, the other allele harboring a c.803G>C substitution was either ABO*cisAB.05 or ABO*BA.06 allele. The ABO*cisAB.05 and ABO*BA.06 alleles remain indistinguishable despite routine serological testing and ABO genotyping. To the best of the author’s knowledge, this is the first case report of these variants discovered in a Cambodian individual residing in Korea.

The interlocking nail is used as a valuable method in treating humerus shaft fracture because of the merit, including relatively simple procedure, one of the most stable fixation methods, and allowing early ROM excericise and low complication. Fourteen pateints with humerus shaft fractures were treated using interlocking nail at the Department of Orthopaedic Surgery Paik Hospital from Jan.1993 to Oct.1994. l. Among the 14 pateints, average age was 34.8 years and 9 cases were male and the most common cause of injury was traffic accident. 2. Associated injury including 3 cases of ipsilateral scapular fracture, I case of ipsilateral clavicle fracture, and 1 case of brachial plexus injury, and 1 case of radial nerve injury. 3. The mean duration of the radiologic bone union was 8.6 weeks. 4. There was no serious post operative complication such as non-union, infection, bending or rotational deformity at fracture site, impingement syndrome, metal failure of the nail or interlocking screws. 5. To prevent the impingement syndrom and rotator cuff injury, we countersinked the proximal end of the nail into the humeral head and minimized skin incision.

In the assessment of thoracolumbar burst fractures, computed tomography(CT) is superior to other imaging modalities, especially when a more definitive assessment of the posterior elements of the spine or the nueral canal is desired. A few authors have reported the relationship between traumatic spinal canal stenosis and neurologic deficits. Authors analysed 64 patients with thoracolumbar burst fractures about the relationship between traumatic spinal canal stenosis and neurologic deficits using plane x-ray findings and CT scans. The results were as follows; 1. There was no difference of kyphotic angle and anterior vertebral height loss between neurologic deficit group on lateral plane x-ray findings. 2. The incidence of injury of the superior endplate was 100%(64/64); of the inferior endplate 53%(36/64); of the posterior element 45.3%(29/64). 3. Twenty(69.0%) of 29 patients with disruption of posterior element had neurologic deficits, while fourteen(40.0%) of 35 patients without disruption had neurologic deficits. 4. Spinal canal ratio of 35.3% or more at the epiconus level, 56.0% or more at the conus medullaris level, and 65.3% or more at the cauda equine level were significant factors for neurologic deficits in thoracolumbar burst fractures. Spinal canal ratio of 22.0% or less at the epiconus level, 34.5% or less at the conus medullaris level, and 43.1% or less at the cauda equine level were not accompanied with neurologic dieficit in thoracolumbar burst fractures. 5. Fifteen(68%) of 22 patients with neurologic deficit in epiconus and conus medullarsis level had the horsehoe or crescent shape of patient spinal canal, eight (66.7%) of 12 patients with neurologic deficit in cauda equine level had the horsehoe or crescent shape of spinal canal.

Antibodies to high-incidence red blood cell antigens should be considered if panagglutination reactions are noted in all panel cells, and negative reactions to autologous red blood cells are detected on antibody screening and identification tests. In Korea, most of those antibodies are identified through international reference laboratories. To prevent a hemolytic transfusion reaction, antigen-negative red cells should be provided for those patients who have antibodies to red cell antigens. However, this is nearly impossible when the antibody has specificity to high-incidence red cell antigen. In those cases, transfusion of autologous blood, cryopreserved rare blood and the least incompatible blood components can be considered. In the case of surgery, acute normovolemic hemodilution or intraoperative blood salvage can also be considered. For the patients who have antibodies to high-incidence red cell antigens, it should be discussed to set up a national reference laboratory to quickly identify antibody specificities, and to consider establishing rare blood donor registry and frozen rare blood storage/supply system. This article reviews characteristics of antibodies to high-incidence antigens found in Koreans and also the transfusion experiences of those patients based on literature.

Weak D type 102 allele (RHD*01W.102) carrying a missense variant (c.73A>T, p.Ile25Phe) in exon 1 of the RHD has not been reported in Koreans to date. This is the first report of the weak D type 102 allele in the Korean population. The proposita, a 35-year-old woman, showed a serological weak D phenotype in routine RhD typing. Sequencing of all 10 RHD exons and zygosity testing targeting the hybrid Rhesus box revealed this proposita to harbor the weak D type 102 allele, as well as an RHD deletion (RHD*01W.102/RHD*01N.01). Family studies showed that the weak D type 102 allele was also present in her father and older brother (both assumed to be RHD*01W.102/RHD*01) but not in her mother and oldest brother (both assumed to be RHD*01/RHD*01N.01). In silico analysis of the replacement of isoleucine by phenylalanine at position 25 was done with PolyPhen-2, SIFT, and PROVEAN. While PolyPhen-2 predicted the variant as benign, SIFT and PROVEAN predicted it as damaging and deleterious, respectively, suggesting RHD c.73A>T (I25F) as the cause of serologic weak D phenotype. This patient should be treated as D-negative, when transfusion is needed.
