Uremic pruritus is the most common skin manifestat,ion of chronic renal failure nnd cloes not respond to conventional treatment for pr uritus such as antihistamine. Although the pathophysiology of pruritus in uremia is uncliar, UVE3 phototherapy is consi(dered as the most effective and safest, therpy. We report two rases of uremic pruritus treated with LJVB. Initial doses were 70mJ, cm and 60mJ/cm. Pruritus was some relieved after two treatments and nearly completely disappeared after eight, treatments. Total doses were 840mJ/cm and 94G)mJ/

The present study was performed to evaluate the characteristics and incidence of the nail changes in chronic renal failure patients. Sixty-six patients who were admitted to the Department of Internal Medicine between March and December, 19R3 and thirtyn'ine patients who were receiving hemodialysis therapy at the hemodialysis unit during June, 1983 in Seoul National University Hospital, were examined. The results were as follows; 1. The brown band just proximal to the free margin of the nail is a frequent nail change in chronic renal failure patients. The term half-and-half nail can be used when the band is wide enough to call it half and the term brown distal arc may be apposite for the whole. 2 .Among the 66 admitted patients, 21 cases(31.8%,) had half-and-half nails,26 cases(39.5%) had brown arcs and 3 cases(4.5%) had white nails. Overall the brown distal arc was present in 47 cases(71.2%,). 3, Among the 39 patients receiving hemodialysis, 3 casesp. 7p,) had half-and-half nails, 9 cases(23. 1%) had brown arcs and 5 cases(23,l%) had white nails. The brown distal arc was present in 12 cases(30.8%) over all. 4. There was no correlation between the level of impaired renal function and the presence or the width of a brown distal arc.

OBJECTIVES: Of 339 patients with systemic lupus erythematosus(SLE) observed at Seoul National University Hospital in Seoul, 221 fulfilled criteria for lupus nephritis. We evaluated the clinicopathologic findings, outcomes and prognostic factors of patients' survival. METHODS: We searched computer system of our center using disease code for SLE from January 1973 to January 1995 and found 339 SLE patients among whom there were 221 definite lupus nephritis patients. We retrospectively reviewed medical records and investigated the influence of multiple prognostic factors on patients' survival using Cox hazard function analysis. RESULTS: Of 221 patients, 89.6% were female. The mean age of onset of SLE was 27.7+/-10.4 years and the mean follow-up duration was 42.5+/- 40.2 months. The most frequent symptoms at diagnosis were skin manifestations. Hypertension was diagnosed in 21.7% of patients and 21.6% had serum creatinine greater than 1.4mg/dL. Overall, 37.7% were nephrotic. Renal biopsy performed on 159 patients showed the following World Health Organization Class distribution : Class I 1.3%, class II 8.8%, class III 6.3%, class IV 65.4%, class V 13.2%, class IV+V 5.0%. Remission of nephritis was observed in 31.3% of patients. At the last follow-up period, there were 23 patients with deteriorated renal function among 168 patients and renal failure developed in 3.2%. Twenty eight patients died, primarily from infection, with 86.2% and 78.3% 5-year and 10-year survival rates, respectively. Initial presence of renal insufficiency(serum creatinine>or=1.4mg/dL) and treatment with prednisolone only were most important in predicting patients' survival. Combination treatment of high dose prednisolone and cytotoxic drug(azathioprine, oral cyclophosphamide, or iv cyclophosphamide) appeared to be beneficial for nephritis. Treatment modality was only independent risk factor associated with lower survival probability. CONCLUSION: The characteristics of our patients were not so different from those of others. Treatment modality and renal function were important predictors of fatality. Treatment with high dose prednisolone and cytotoxic drug improved the clinical outcome of lupus nephritis, as compared with prednisolone alone.

It has been reported in autopsy that most of the patients with Korean hemorrhagic fever had necrotic areas inthe anterior lobe of the pituitary gland. The high resolution CT of sella was performed to demonstrate thepossible pituitary necrosis in consecutive 13 patients with Korean hemorrhagic fever. Only 3 patients demonstrate normal sellar findings. Ten (77%) out of 13 cases reveal abnormal findings; 2 patients show typical empty sellar and the rest (8 patients) reveal localized low denstiy area in the anterior portion of the sella turcica, which may be from partial empty sella, pituitary infarction or other unknown pathology. The low denisties within the sella will be discussed.

Authors analysed and present chest X-ray findings of serologically proven leptospirosis from Seoul NationalUniversity Hospital, either admitted or referred for serological verification, during recent 2 years. Radiologicalfindings were correlated with the lung specimen finding of experimentally induced leptospirosis in guinea pig. Theresults are as follows: 1. 24 cases(56%) showed positive X-ray findings. 2. Predominent radiological patterns ofinvolved lung were tiny dot, small nodule, rosette density in 11 cases, massive confluent consolidation in 4cases, and diffuse ill-defined veilly increased density in 9 cases. 3. Distribution of pulmonary lesions werebilateral (100%), non-lobar, non-segmental(95%), and there were conspicuous tendency of peripheral lungpredominence. 4. Extrapulmonary manifestation, such as pleural effusion or cardiomegaly was rare. 5. Pulmonarylesions resolved completely usually 5 to 10 days after their appearance. 6. From the gross and microscopicfindings of serially sacrified guinea pig's lung and a case of autopsy, authors conlcuded that fine dot-likedensity in chest X-ray was due to petechial hemorrhage in intraalveolar space at initial stage, growing up toressette density or confluent consolidation as the petechia extends to surrounding lung forming purpura andcoalescent hemorrhage.

Eleven hantavirus isolates were obtained by innoculation of viremic blood, urine, or autopsy tissue specimens from ten HFRS patients, and sera were obtained from five patients with HFRS. The disease was diagnosed by clinical manifestations and indirect immunofluorescent antibody technique. We obtained 6 hantaviruses from gene bank. So, we analyzed 22 hantavirus samples to elucidate the genetic diversity. The hantaviral RNAs were extracted and 365 base-pair complementary DNAs of M segment were obtained by reverse transcriptase polymerase chain reaction (RT-PCR) and 326 base-pair by nested PCR. The nucleotide sequences of amplified cDNA fragments were determined by the direct sequencing method using automatic DNA sequence analyzer. We got full M segment sequences of 28 reported hantaviruses with medline searching, and aligned them with our 22 samples, and the phylogenetic analysis for nucleotide and amino acid sequences were done by the Clustal method. The nucleotide and amino acid sequences of Hantaan virus 17 samples showed high (above 90%) homology with 76-118 strain, but 2 samples showed significant differences with 76-118 strain and with other 17 samples. The 3 Seoul virus samples showed high intraspecies differences in 1 sample, and showed singnificant differences with SR-11 strain. In phyogenetic tree analysis, Puumala virus and Hantavirus pulmonary syndrome viruses showed high homology, but Hantaan and Seoul viruses showed significant genetic diversity among strains. In conclusion, hantaviruses isolated from HFRS patients showed genetic diversity compared with those isolated from rodent hosts.

Recently, it becomes conspicuous that the network should have enough communication bandwidth and be organized with steadiness to operate and support hospital information system successfully. Seoul National University Hospital completed to reconstruct legacy network which had been used since 1995. We had a consultation to diagnose the current problems and reconstructed the network according to the consultation. The design of network architecture was mainly focused on the circuit route in case of error condition and the suitable bandwidth for the easy communication. We also regulated the use of unsuitable protocols which might broadcast inappropriate data packets over the whole network. After 6 months of operation we evaluated the performance of newly constructed network. The average traffic rate from the input port of main servers was 0.5% and that from the output port was 6% separately. The average traffic rate on the overall ATM backbone showed around 1 %.From the result, we concluded that the newly constructed network had such an enough capability supporting hospital information system without any interruption. Furthermore, we expect that it will be sufficient to support the additional traffic increment by PACS and group ware applications.
