Analysis of Urinary Mass Screening for Second Grade of Elemantary School Children in Paju City

PURPOSE: We performed urinary mass screening(UMS) program for 2,804 children of second grade elemantary school 8 years of age in Paju city with cooperation of Paju City Health Center to determine the prevalence of asymptomatic proteinuria and hematuria, and to estimate the risk of incipient renal diseases. Also we attempted to evaluate the significance of hematuria in UMS in addidtion to proteinuria. METHODS: 2,804 children of the 2nd grade of elementary school who lived in Paju city were included to our UMS program in 2000. They were constituted with 1,428 boys and 1,376 girls. The screening program was carried out in 3 steps. The 1st screenig test was performed at schools and then students with abnormal results were examined repeatedly at Paju City Health Center and our hospital. Those students who showed proteinuria and/or hematuria in the 1st and 2nd test were referred to our hospital to undertake the 3rd close examination including physical examination, laboratory tests and radiologic tests. RESULTS: (1) The prevalence of urinary abnormality in the 1st screening test was 8.3%(233 students), comprised of 5.9% of boys, 10.8% of girls. (2) Among 2,804 children tested in the first screening, prevalences of asymptomatic proteinuria and isolated hematuria were 64(2.3%), 163(5.8%) respectively, and the prevalence of proteinuria with hematuria was 6(0.2%). (3) Among 233 students with urinary abnormalities at the 1st screening test, 102 students applied to the 2nd test. 32 children, about one third of them, were also found to have abnormal urinary findings; isolated hematuria 30, proteinuria with hematuria 2. (4) Those findings of clinical evaluation for children with isolated hematuria at the hospital showed as follows: idiopathic isolated microscopic hematuria 21, normal 6, urinary tract infection 1, idiopathic hypercalciuria 1 and simple renal cyst 1. Those 2 students with proteinuria and hematuria seemed to have chronic glomerulonephritis. CONCLUSION: (1) The clinical evaluation for children who showed positive results at the 1st screening test should be done judiciously. Because of high false positive rate, almost who showed positive results was normal, only a few of them had pathologic conditions. In this study, actual incidence of incipient renal diseases in children of 8 year old was calculated to be 0.4%. (2) The definite conclusion whether a urinary mass screening test can alter the prognosis of incipient renal diseases could not be drawn with this study. Further study must be necessary. (3) We could acknowledge the significance of hematuria in UMS, but it is necessary that one should be judicious in managing and follow-up those that show abnormal results.

Occurrence of Gray Mold Caused by Botrytis cinerea on Cryptotaenia japonica in Korea

A gray mold disease occurred on Cryptotaenia japonica in Korea. All the isolates of Botrytis sp. from the lesions of the diseased plants were identified to be B. cinerea based on the morphological characteristics. Conidia formed on conidiogenous cells were not in chains, hyaline to pale brown, unicellular, ellipsoidal to obovate with a single hilum at the base, entirely verruculose, and 6.3-11.3~6.3-10.0 microm in size. Pathogenicity of the fungus was proved by artificial inoculation on C. japonica. This is the first record of gray mold on C. japonica caused by B. cinerea in Korea.

A Case of Acute Necrotizing Encephalopathy

This disease predominantly affects infants and young children living in Japan and Taiwan, and manifests itself as acute encephalopathy following viral infections. The hallmark of this encephalopathy is multifocal, symmetric brain lesions affecting bilateral thalamus, brainstem tegmentum, cerebral periventricular white matter and cerebellar medulla, which can be visualized by computed tomography and magnetic resonance imaging. Both the gray and white matter are involved, with neuropathological evidence of local breakdown of the blood-brain barrier. The prognosis was poor in the 1980s, but has improved recently. A characteristic combination of focal neurologic signs is often recognized as the sequelae. We experienced a case of a 7-month-old male infant who had been transferred to our hospital for comatous mentality and clonic seizure of both arms and legs. We report this case with a review of the related literatures.

A Case of Tansient Hyperphosphatasemia

We examined a male infant with transient increase in alkaline phosphatase(ALP) activity. The 25-month-old infant was admitted to a local hospital because of pneumonia of unknown etiology. Initial laboratory investigation revealed a serum ALP of 11,260U/L, which was comparable to that of bone isoenzyme on the electrophoresis pattern, There was no evidence of hepatitis, skeletal or intestinal diseases. The hyperphosphatasemia disappeared 3 months later. We report a case of transient hyperphosphatasemia diagnosed inci- dentally in the course of management of pneumonia.

A Case of Branchio-Oto-Renal Syndrome

Branchio-oto-renal(BOR) syndrome is an autosomal dominant disorder. The pathophysiology of this syndrome is unknown. BOR syndrome has a wide range of clinical manifestations affecting the branchial, auditory and renal systerns. Associated abnormalities of the face, lacrimal duct, palate and ureters have also been described. However, the major clinical findings associated and/ or ear pits, and renal anormaly. We experienced a case of a 15-day-old rnale newborn who had visited our hospital for deformed auricle and atresia of external auditory canal found at birth. We report this case with a review of the related literatures.

A Study on the Intertrochanteric Fracture / 대한정형외과학회잡지

As trochanteric fractures frequently occur in the elderly patients and complications such as pneumonia, thrombo-embolic disease, decubitus ulcer, and urinary tract infection are common, early mobilization after open reduction and internal fixation with hip nail are the standard treatment. Since 1931 when Smith-Peterson first introduced a tri-flanged nail, further more, since 1941 when Jewett pioneered the one-piece nail by adding a solid plate to a Smith-Peterson nail, numorous implants including threaded pins, screws, nails, and plates have been modified and desiged for fractured hips till now to achieve early ambulation and to maintain stable reduction. In 1955 Pugh and Ken introduced a sliding nail-plate and Schumpelick described the use of sliding screw-plate, which was modified further by Callender and Holt pioneered the concept of heavy nail in 1963. Recently compression sliding screw-plate is popular. Also many surgeons such as Evans, Dimon and Hughston, Sarmiento, and Boyd and Anderson have attempted to provide stable fixation of fracture by altering the position of fracture fragments to improve the mechanical resistances of bone to disruptive forces of weight-bearing. The surgical procedures of open reduction and internal fixation were carried out and followed for more than 6 months on 45 intertrochanteric fractures at Department of Orthopedic Surgery, Seoul National University Hospital, from Jan. 1968 to June. 1975 and the results were observed as follows. 1. Of 45 cases of inter-trochanteric fractures 28 cases occurred in man, 17 cases in woman and each mean age was 54 years in man, 74 years in woman. 2. Of fixation devices, Smith-Peterson nail-plates were used in 19 cases, Jewett nails in 15 cases, compression sliding screw-plates in 9 cases, Smith-Peterson nail in 1 case, and Ken sliding nail-plate in 1 case. 3. Stable fractures occurred in 10 cases were fixed internaly after anatomical reduction. 4. Dimon-Hughston reductions and Jewett Nailing were achieved in 11 cases of 12 unstabIe fractures and had disadvantages such as some limitation of R.O.M. of the affected hip, shortening, and valgus deformity. 5. Of 9 unstable fractures treated by compression sliding screw-plate 7 cases were reduced as anatomicaly as possible and 2 cases were reduced non-anatomicaly because of impossible anatomical reduction but good results were obtained except one failed nailing. 6. Of 7 failures, 6 cases resuIted from failures of nailing during operation and only 1 failure resulted in varus defermity after Dimen-Hughston reduction with Jewett nail.
