A lg year-old female patient with pityriasis lichenoides et varioliforrnis acuta (PLEVA) was been treated with PUVA, At first, she was treated with tetracycline for 8 weeks with improvement somewhat. But 2 months later, her skin lesions aggravated slowly. So, we tried to treated her with PUVA and then she was cleared completely. The initial dose of UVA was 5 J/cm The UVA dosage increased by 10g of the previous exposure and increased to the maximum dose, 15 J/cm The patient exposed to UVA R times per week. 12 times after the PUVA therapy, the skin lesions begin to improve and completely improved at 21 times of Pl.JVA therapy. She was followed up every week and there was no side effect except hyperpigrnentation till 24 months. The total dose during treatment is 210 J/cm.

Crohn's disease, a chronic relapsing, multisystemic, inflammatory disorder, may involve any part of the gastrointestinal tract and shows a cobblestone-like appearance on intestinal mucosa. There are also extraintestinal features, including lesions of the skin, eye, and joints. Ulcers, fissures, sinus tracts, abscesses, and vegetant plaques have been reported for the perianal skin lesions of Crohn's disease. We experienced a case of Crohn's disease in a 21-year-old Korean female showing a skin lesion with a cobblestone-like appearance in the perianal region.

A clinical study was made on the 28 cases underwent prostatectomy during the 5 year-period from 1964 to 1968. The results are summarized as follows: 1. The patient underwent prostatectomy revealed increasing tendency in incidence, residual urine in average and being usually in the age range between 60 and 70 years. 2. The degree of prostatic enlargement was mostly grade 11 on rectal palpation and the removed prostate was 49. 3gm. in average weight. 3. Blood loss attributable to the operative manipulation was 1143 cc. in average. The patients underwent prostatectomy were discharged on the average 21.3 days postoperatively in which postoperative indwelling catheter was left in place for 15.3 days in average. 4. Postoperatively the convalescence was uneventful and the residual urine was disappeared or decreased markedly. 5. In the patients underwent prostatectomy via retropubic approach operative blood loss was mild and postoperative duration of indwelling catheterization was short as compared to that via the suprapubic approach. 6. No serious complication other than epididymitis developed in a few patients was observed postoperatively. 7. Suprapubic prostatectomy was found to be suitable for the patient with marked prostatic enlargement while the retropubic one yielded less tissue damage and somewhat rapid postoperative convalescence as compared to the former.

Secondary cutaneous cryptococcosis may occur earlier than other manifestations of disseminated cryptococcosis. A 68-year-old woman presented with multiple ulcerative lesions on the right calf of 2 weeks duration. She had been treated with antibiotics, but the lesions spread rapidly. The initial clinical impression was necrotizing fasciitis, but routine KOH mounting from the ulcerative lesions showed numerous budding yeast cells with peripheral clear zones and further investigations including a skin biopsy, tissue cultures and India ink preparations allowed a rapid and definitive diagnosis of cutaneous cryptococcosis. Studies for other evidence of infection elsewhere revealed an asymptomatic pulmonary lesion. We report a case of secondary cutaneous cryptococcosis clinically mimicking necrotizing fasciitis that occured before other manifestations of disseminated cryptococcosis.

A 28-year-old man presented with a 6.0 * 5.0 cm sized ulcer on the anterior chest and widespread copper-red colored maculopapular eruptions. There was no past or family history of syphilis sign or STS. He had been taken imposition of hands twice to treat chronic hepatitis about 4 months prior to presentation. Thereby, the ulcerative lesion on the anterior chest developed as a result of erosive trauma through contact with infected fingernails. The clinical features and serologic tests as well as biopsy findings were consistent with syphilis. Spirochetes were observed under the dark field examination of the anterior chest lesion. On Warthin-Starry staining, spirochetes were identified in the epidermal area of the papular lesion. We report a case of unusual transmission of syphilis.

BACKGROUND: It has been known that blood group antibodies are not produced in the neonatal period and that if the antibodies exist, they are probably maternal in origin which had crossed the placenta. There have been several studies conducted abroad on when these antibodies are formed but none has been done in Korea. This study was carried out to determine the ABO blood type and blood group antibodies in children from neonates up to 5 year old. We hoped to determine when and in what pattern blood group antibodies were produced. METHODS: We selected 337 children from neonates up to 5 year old who were admitted to Hanyang university Hospital in Seoul or Kuri from 1994 to 1996. Cell typing was done immediately by the slide method. The anti-A and anti-B used for cell typing were supplied by Immucor (Norcrosis, Ga) . Sera were stored at -70 degrees C until they were tested for ABO blood group antibodies by the standard saline test tube method. When uncertain results were obtained, a drop of the mixture was placed on a slide and observed under a microscope. RESULTS: ABO blood group antibodies were detected in 9 of 50 (18%) infants less than 1 week old and in 10 of 51 (20%) infants between 1 week and 3 months of age. The pattern of ABO blood group antibody production was similar to that of the fetal period up to 3 months after birth, after which antibody production increased rapidly to reach approximately 80% at 6 months of age, There was no difference in ABO antibody production between boys and girls. The antibody formation pattern of group A and group B infants less than 6 months of age showed anti-A to be 35% and anti-B to be 20%. In group O infants of the same age, anti-A was positive In 42% and antral-B In 33%. However, after 6 months of age, there was no difference in antibody production among groups A, B, or O. CONCLUSIONS: Antibodies directed toward ABO antigens were detected in 19 out of 101 (19%) infants less than 3 months old. We therefore believe it is necessary to Perform serologic typing as well as cell typing in these Infants. Furthermore, the emergency transfusion of type A or B blood to a type O infant under the impression that anti-A and anti-B do not exist should be forbidden.

Korean Journal of Medical Physics 2008;19(4):219-226
In this study, we have conducted characterization of imaging performance for a flat panel digital X-ray detector using amorphous Selenium and a-Si TFT which was developed by the authors. The procedures for characterization were in concordance with internationally recommended standards such as IEC (international electrotechnical commission). The measures used for imaging performance characterization include response characteristic, modulation transfer function (MTF), detective quantum efficiency (DQE), noise power spectrum (NPS), and quantum limited performance. The measured DQEs at lowest and highest spatial frequencies were 40% and 25% respectively, which was superior to that of commercial products by overseas vendor. The MTF values were significantly superior to that of CR and indirect type DRs. The quantum limited performance showed the detector was limited by quantum noise at the entrance exposure level below 0.023 mR, which is sufficiently low for general X-ray examination.
