The author obtained index of red cell volume distribution width(RDW) and other red cell indices in 210 patients of various hematoncologic conditions and 200 healthy control group using, an automated blood analyzer, Coulter Counter Model S-plus II. This study performed to classify various etiologic anemia based on the MCV and RDW, to evaluate availability to the differential diagnosis in korean anemic distoders somewhat different from etiologies of anemias in foreginers. In the most of cases, the increase or decrease of MCV were always combined the pararell changes of MCH and MCHC: But the values of MCV and RDW were not correlated in control group and patient group. So the terms of heterogenous of homogenous anemia were meaningful morphologic classification than hypochromic or normochromic anemia. The heterogenous microcytic anemia contained iron deficiency anemia. In heterogenous normocytic anemia, myelophthisic anemia, acute leukemia were contained. In heterogenous macrocytic anemia, megaloblastic anemia, hemolytic anemia were contained. The homogenous microcytic anemia was observed in anemia of chronic disorders. In homogenous normocytic anemia, acute blood loss, chronic leukemia, multiple myeloma were contained. The aplastic anemia was belonged to homogenous macrocytic anemia. The diagnostic significance of RDW in hemoglobinopathies is most importhant. But this study was not contained hemoglobinopathies. Instead RDW was very helpful to differential diagnosis of most common anemias, iron deficiency anemia and anemia due to chronic disorders in Korea.

3.Computerization of Patient Data Management for Vology by Automatic Coding System : A Program Using dBASE IV in Personal Computer.
Korean Journal of Urology 1990;31(5):734-740
In recent years there are so many medical informations that urologists should know. Computer systems offer new opportunities for the storage and manipulation of hospital informations. A computer-based system for urologic patient data management has been designed and developed by the authors. This program was written in dBASE IV language and could be used in IBM PC/AT (16 Bit) with at least 20MB hard disk drive. The main features of this program include storage and retrieval of data easily by pull-down menus using automatic coding system for diagnoses and operation names. Searching a case or a group of cases could be performed by name, chart number and filters (date of input, diagnosis code, operation code, urology number). And they are easily printed out by two different print forms. The automatic coding system is that after diagnoses and operation named are typed, their codes are automatically registered. The urologic code system for automatic coding was also designed by the authors. In our experience this computer-based urologic patient data management system by automatic coding is very useful, easy to handle, and minimizing input errors.

Moyamoya disease is an unusual vascular disorder highlighted by progressive bilateral internal carotid artery occlusion and collateralization of intracranial blood flow. The purposes of the bypass procedures : 1) reduce or arrest of the chance of repeated ischemic attack by making the additional collateral blood flow, 2) decrease the chance of repeated bleeding by reducing the number of moyamoya vessels. During the period from June 1989 through February 1991, 8 moyamoya diseases associated with intraventricular hemorrhage were operated by STA-MCA anastomosis plus EMS. Results are as follows : 1) Slightly female dominancy in incidence(5 : 3), and all of the patients were middle aged(range 32 to 55 years). 2) All of the patients had sudden onset of headache, and most patients whad neck stiffness and vomiting. 3) In all of the patients, confirmatory diagnosis could be done by angiography, and all of the patients had gypical angiographic findings of moyamoya disease. 4) All of the patients had IVH in brain CT scan. 5) All of the patients were surgically treated : STA-MCA anastomosis plus EMS. 6) The postoperative revascularization rate was 89%(8 sides in 9 sides). 7) The postoperative results were excellent in 5, good in 1, and death in 2. The rarity of such lesions in KOrea and their surgical results are reviewed briefly.

A clinical review of 31 cases of multiple myeloma which were diagnosed by criteria of the SWOG between May 1983 and February 1990 at Yeungnam University Hospital was done. The results were as followings: 1. The peak incidence was in 7th decade and male to female ratio was 1.8:1. 2. The most common presenting symptom at first diagnosis was bone pain (58%), but fever, dyspnea, dizziness and palpable mass were also noted. 3. The distribution of laboratory findings as following diagnostic criteria of Southwest oncology group (SWOG): Plasmacytoma on tissue biopsy was noted 6 cases, bone marrow plasmacytosis with more than 10% plasma cells was 22 cases, monoclonal globulin spike on serum electrophoresis was 24 cases, lytic bone lesions was observed 22 cases. 4. Initial clinical stages were classified as 2 cases in stage I, 3 cases in stage II, 26 cases in stage III (84%). 5. Immunoelectrophoresis revealed the distribution of IgG 64%, light chain 22%, IgA 10%, Kappa to Lambda ratio of 1.1:1. 6. Hematologic & biochemical findings revealed anemia with <8.5% of hemoglobin in 42%, hypercalcemia with <10.6 mg% of serum calcium in 22%, azotemia >2.0 mg% of serum creatinine in 19%. 7. The multiple punched out lesion of bone x-ray examination were noticed skull (65%), rib (42%), L-spine (35%), pelvis (23%), T-spine (19%). The initial skeletal roentgenographic findings showed osteoporosis, osteolytic lesion and fracture in 55%, only osteolytic lesion in 23%, only osteoporosis in 10%. 8. Complications of multiple myeloma, such as 10 cases of renal impairment, 8 cases of infection, 16 cases of compression fracture of spine were observed.

The surgical intervention for secondary developmental cervical spinal stenosis that results in myelopathy and radiculopathy has been modified by technical improvement to obtain more reliable enlargement of the cervical spinal canal. The authours have experienced good results with the modified open door expansive laminoplasty, so we report this article. The patients were treated by surgical intervention during the period from October 1989 to February 1991. The results obtained were as follows : 1) The average age was 54.7 years, and the sex distribution ratio of female to male was 2 : 8. 2) In clinical symptoms and symptoms of both myelopathy and radiculopathy. 3) In morphological analysis of lesions, all patients except one case had lesions over 3 levels, The lesions were spondylosis, spondylosis combined with soft disc herniation, spondylosis combined with OPLL, spondylosis combined with OPLL and soft disc herniation, OPLL and OYL in the order of frequency. 4) The operation method was as follows : after the patient was positioned in modified Concorde position, open door lamina was anchored to faced joint capsule and surrounding tissue with nylon sutures. And then the raw epidural space was covered with Lyodura by the modified Hirabayashi method. By this method, reclosure of widened spinal canal was prevented. 5) The outcomes were evaluated by JOA score difference between preoperation and post operation times. The outcome of recovery rate was 100% in five cases. Therewere no aggravated or unimproved cases. The results were excellent 8 cases, good 1 case, unchanged 0 case, poor 0 case and expired 1 case.

Recently we performed a modified sternum-splitting approach in surgery for anterior space-taking lesion in the upper thoracic region. In contrast to the original trans-sternal approach introduced by Cauchoix, we cut only the manubrium and split it using vertebral spreader. After reaching the anterior surface of the cervico-Thoracic vertebrae, the central portion of the vertebral body was removed with air-drill under an operating microscope. The longitudinal bone defect of the vertebral bodies was filled with a bone graft obtained from the iliac bone. Removal of the space-taking lesions in the cervico-thoracic junction and upper thoracic region can be performed safely by utilizing the modified sternum-splitting approach. This approach can be applied also to endarterectomies at the origins of the vertebral arteries and the subclavian artery.

8.Molecular Characterization of Clinical and Environmental Strains of Cryptococcus neoformans Isolated from Busan, Korea.
Journal of Bacteriology and Virology 2010;40(2):91-98
Cryptocococcus neoformans is an encapsulated yeast that can cause life-threatening infections in immunocompromised patients. In this study, the genetic variability and epidemiological relationships of clinical and environmental isolates of C. neoformans from Busan, Korea, 2000~2005 were investigated. A total of 12 strains of C. neoformans, 7 clinical and 5 environmental isolates were analyzed by random amplified polymorphic DNA (RAPD) using three different primers and PCR-fingerprinting with a minisatellite-specific core sequence of phage M13. All strains belonged to C. neoformans serotype A and mating type MATa. Two different RAPD profiles (I and II) and a single pattern by M13 PCR-fingerprinting were identified. The major RAPD profile was pattern I (8 of 12 strains) and pattern II was identified from 2 clinical and 2 environmental strains, which clearly distinguished among isolates. Clinical strains with pattern II were isolated from the patients with HIV positive. Taken together, molecular patterns provide a good characterization of strains of C. neoformans as a heterogeneous group and epidemiological relationships in clinical and environmental strains.

10.Molecular Typing of Clinical Cryptococcus gattii Isolates in Korea.
Journal of Bacteriology and Virology 2012;42(2):152-155
Cryptococcus gattii causes life-threatening yeast infection in the pulmonary and central nervous systems of humans and animals, and traditionally has been considered to restrict into the tropical and subtropical areas. Despite rare incidence of cryptococcosis caused by C. gattii in Korea, three strains of C. gattii isolated from cryptococcosis patients between 1993 and 2010 were identified. To determine the genetic diversity, 3 strains of C. gattii were typed using PCR fingerprinting with primer M13 and the restriction fragment length polymorphism (RFLP) of orotidine monophosphosphate pyrophosphorylase (URA5) gene. All isolates were identified as serotype B and MATalpha mating type. The molecular types of each strain, on the other hand, turned out to be distinct belonging to VGI, VGII or III types, respectively. Although the travel histories of the patients were not available, clinical C. gattii strains isolated in Korea may represent the diverse molecular types existing worldwide.
