BACKGROUND: Definite criteria for the diagnosis and treatment evaluation for different clinical stags of syphilis are not yet present dute to the inability to dultivate Treponema pallidum in vitro. However, as the staining methods and the serological tests currently used have their limitations, a more definite method for its confirmation is needed. Polymerase chain reaction (PCR), due to its high sensitivity and specificity, is currently being applied to the detection of T. pallidum. OBJECTIVE: We have used PCR for the detection of T. pallidum DNA in various clinical specimens in orber to evaluate its potenital as a diagnostic tool. METHOD: Clinical specimens were collected from patients with different stages of syphilis who visited ithe Deparment of Dermatology of Yonsei medical Center for 1 year beginning from May, 1991. Sera from 63 patients, cerebrospinal fluids from 24 patients, amniotic fluids from 3 patients, and 21 tissues from 19 patients were subjected to PCR and the results were analyzed to evaluate its usefulness as a diagnostic and treatment evaluation tool. A portion of the T. pallidum-specific chromosomal DNA, tpp47, which encodes the 47 kDa surface protein, was used as the template DNA to amplify the 658 bp DNA fragment, and the following results were obtained. PCR using primers 47-1 and 47-2 were applied to amplify 658 bp DNA fragments from the T. pallidum-specific tpp47 gene encoding 47 kDa surface protein. RESULT: 1. To evaluate the sensitivity of the PCR, T. pallida and their chromosomal DNA were diluted. The diluents contataining a single organism and 1 fg of the chromosomal DNA showed positive reactions by the amplification. 2. Specificity of the PCR was determined by using T. pallidum, 4 species beloging to genus Treponema, and 9 species of nonpathogenic or pathogenic organisms. A positive reaction was obtained only when T. pallidum chromosomal DNA was used. 3. PCR was positive in 5 of 9 (55%) sera in primary syphilis, 22 of 26(84%) in secondary syphilis, 3 to 15(20%) in early latent syphilis, 1 of 19 (11%0 in late latent syphilis, 2 of 2 (100%) in neurosyphlis, and 0 of 2 (0%) in congenital syphilis. The differences in the positive rates were statistically significant (P<0.01) in all stages except neurosyphilis and congenital syphilis, as their numbers were too smalll to deduce any significant meaning. Despite their high VDRL titers, the positive rate in early latent syphilis was relatively low when compared to the rate in secondary syphilis. 4. Follw-up PCR of sera in some patients showed positive results 9 months after treatment. However, some with negative PCR before treatment showed positive results after treatment. 5. PCR was positive in 1 of 1 (50%) cerebrospinal fluid in primary syphilis, 3 of 14 (21%) in secondary syphilis, 2 of 7 (29%) in early latent syphilis, and 1 of 1(100%) in neurosyphlis. The differences in the positive rates showed no statistical significance in relation to the clinical stages. Cerebrospinal fluid VDRL test, white blood cell count, and protein content showed no correlation to the PCR results in early syphilis patients. 6. Amniotic fluid showed a positive PCR result only in a pregnant woman whose serum showed a high VDRL titer and a positive PCR. 7. PCR positive rates were 90% in frozed tissues and 50% in paraffin embedded tissues. CONCLUSION: From the results, it is suggested that PCR is not suitable for treatment evaluation but is useful for the detection of T. pallidum in sera of secondary syphilis patients and syphilitic lesions, and for the confirmation of the diagnosis the diagnosis in these cases.

Using the FTA-ABS complernent test, 32 skin speciruens from 27 patients with primary and secondary syphilis and a stomach specimen from a patient with suspected gastric syphilis which were confirmed by clinical history, physical examination, VDRL, FTA-ABS, and 19S(IgM)-FTA test, were tested. The following results were obtained. 1. In the darkfield examination, 7 of the 9 specimens(78%) were positive and in the FTA-ABS complernent test, 20 of the 33 specimens(61%) were positive. 2. The ratio of agreement between the darkfield examination and the FTA-ABS complement test was 89%. 3. In the chancres, macular syphilids, and condyloma lata, T. pallida were diffusely scattered in the epidermis, dermoepidermal junction, connective tiasue, and vascular walls, whereas in the papular syphilid T. pallida were mainly aggregated in the the epidermis, dermoepidermal junction, papillary dermis as well as the blood vessel walls in the papillary dermis. From these results, the FTA-ABS complement test can be considered to be a useful method for both the diagnosis and research of syphilis. It is especially helpful in cases where serological or histopathological study can not confirrn the diagnosis as when internal organs are involved.

BACKGROUNDS: An inhibitory effect of magnesium L-ascorbyl-2-phosphate (VC-PMG, a stable derivative of ascorbic acid) on melanogenesis has been described. Furthermore, glabridin in licorice is known to have inhibitory effects on melanogenesis and widely used for raw materials for depigmenting agents. OBJECTIVE: The purposes of this study are to provide objective data by measuring the visual clinical effects of VC-PMG with the colorimeter and to promote the development of de-pigmenting agents. METHODS: 20 volunteers joined the study. With an artificial UVB irradiation, eight tanned areas were made on the inner side of the forearm. During two months, each tanned area was treated with five whitening cosmetics with 3% VC-PMG and increasing concentration of licorice from 0% to 3%. Darkness degree of each area was measured weekly by the colorimeter and the visual assessment. RESULTS: For all cosmetics, whitening effect was measured by colorimeter and visual as-sessment. The cosmetic containing VC-PMG 3% and licorice 1% had more whitening effect than any other cosmetics of different concentrations. Moreover, VC-PMG 3% alone also had whitening effect in some volunteers. CONCLUSION: VC-PMG was clinically found to have whitening effect.

Iliofemoral vein thrombosis is a serious disease causing major morbidity, such as phlegmasia alba dolens, phlegmasia cerulea dolens, fatal pulmonary embolism, and post-thrombotic syndrome. Systemic anticoagulation therapy with heparin and coumadin often shows no effect and thrombectomy often results in poor long term patency due to recurrent thrombosis. Some recent studies have reported good results by catheter-guided thrombolysis therapy (CGTT) in iliofemoral vein thrombosis. Authors have experienced a good result by CGTT in an old (aging 7 weeks) iliofemoral vein thrombosis. (Case) A 21 years-old female patient with diffuse edema of left thigh and leg was admitted in SNUH. Her parents notified her abnormal gait at the age of three, but no treatment was done. In Jan. 1998, she was diagnosed as spastic diplegia due to cerebral palsy and underwent orthopedic surgery (semitendinosus tendon transfer) at other hospital. After long leg cast for 6 weeks, swelling of her left thigh developed, which waxed and waned. Seven weeks thereafter, she was diagnosed to have left iliofemoral vein thrombosis and transferred to our hospital. After initial evaluation and systemic heparin therapy, we performed CGTT via left popliteal vein puncture. After successful passage of guidewire, serial balloon dilatation and intra-clot urokinase infusion was done. Total 3.5 million units of urokinase was infused for 28 hours with simultaneous intravenous heparin. Despite of some residual thrombi, the venous flow of iliofemoral vein was restored with no complication and her symptom has much improved. Patent venous flow was detected at 6 months follow-up doppler examination.

From January to December of 1990, we have evaluated VDRL reactivity among 17,142 apparently normal Korean adults which consisted of 9,151 blood donors in Seoul area, 2,682 pregnant woman delivered at Severance Hospital, Yonsei University and 5,309 physical examinees. The VDRL-positive rates were 0.3% in the blood donors, 0.1% in the pregnant women and 0.8% in the physical examinees but the rates were higher in the age group of 50 years or older. The VDRL titers were below 1:2 in 94% of the VDRL-positive pregnant women and physical examinees. From the comparison of the results obtained by the present author group since 1977, i.e., 2.5 % in 1977, 1.1 % in 1981, 0.6 % in 1986 and 0.4 % in 1990, it is evident that the prevalence of syphilis in Korea is continually decreasing.

Syphilis is a communicahble disease caused by the motile microaerophilic spirochete Treponema pallidum, which is only a netural pathogen for human. Prevalence of syphilis and other sexually transmitted diseases has traditioially fluctuated with changes in sccia, conditions and sexual behavior. Although sexual contact is the main route of transmission, T. pallidum may also be infected through direct contact with syphilitic lesions, blood transfusion, ingestion of menstrual blood or vaginal secretions, or trsnsplacental transemission. Fomites as the means of transfer is only hypothetical and account for very few, if any, infection. Prosectors, blood handlers and laboratory technicians are at risk for accidental inoculation with infected materials. In extremely unusual circumstances, infection by means of contact with a skin lesion and human bite have been reported. We report two cases of eyphilis following the abnormal imposition of hands, which caused unnecessary erosive trauma with fingernails,
