BACKGROUND: The proportion of patients with subacute cutaneous lupus erythematosus(SCLE) is considered to be 10% among the total LE population in western countries. The morphology of LE-specific skin lesions in SCLE : appear as papulosquamous erythema or annular erythema developing mostly on the exposed areas. Among Korean patients with LE the prevalence and the pattern of cutaneous eruption of SCLE may be different from those patients of western countries. OBJECTIVE: To obtain the prevalence and the morphological characteristics of cutaneous lesions in Korean patients with SCI E v;ere the main objectives. METHODS: With 7 cases of SCLE, clinical dermatologic examinations for the character, the distribution, and the clinical course of those cutaneous lesions, and for the extent of systemic symptoms and LE-related laboratory abnormalities in each patient were performed. Results/Coeclusion. The prevalence of SCLE among Korean patients with LE or latent LE was much lower than those seen in Caucasians. The pattern of cutaneous lesions were papular/ papulosquamous erythemas with no (or rare) cases of annular erytherna among those patients diagnosed as SCLE. ~Other cl~inica! features were similar to Caucasian patients. It seems that there are some racial differences in the cutaneous manifestat.ions of LE, which may be relevant to the dissimilarities in immunogenetic backgrounds between different racial groups.

Before impression making in the fixed restorations or other prosthesis, hemostatic solutions are used for hemostasis and moisture control. Hemostatic solutions effectively control bleeding but their major ingredients, acid removes smear layers which are formed in the tooth preparation, exposes the dentinal tubular orifices which are occluded by smear layers, makes dentinal tubular fluid displace more easily to the various external stimulus, and according to the hydrodynamic theory, consequently causes dentin hypersensitivity. To know the effect of hemostatic solutions on dentin permeability, coronal dentin discs, 1 mm in thickness, were prepared from extracted third molars free from decay and wear, and a spilt chamber device was used. Hydraulic conductance values and SEMs, which were measured before and after treatment with Astringedentr , Altract and Epri-dent , were compared and analyzed. The following conclusion were drawn : 1. Hydraulic conductance values which wee measured after the treatment of hemostatic solutions were increased in all groups(p<0.05). 2. %change values of hydraulic conductance were compared but no significant difference was found among the three hemostatic solutions(p<0.05). 3. on SEM observations of all groups, after treatment smear layers were removed and dentinal tubular orifices were partially exposed. on the basis of these conclusions, the reckless use of hemostatic solutions should be restricted, and when in use, various methods should be considered to protect dentin.

Renal vein thrombosis is usually a complication of multiple underlying renal disease rather than primary process. High incidence of renal vein thrombosis in patients with nephritic syndrome, which suggest the nephrotic syndrome play a paramount role in the genesis of renal vein thrombosis or thromboembolic phenomena. But these are likely to relationship of “egg and chicken”, and then we cannot determine what is primary of these. Recently authors experienced a case that was questioned renal vein thrombosis with nephrotic-syndrome clinically, laboratory and preliminary radiologically, and this case in confirmed by selective left renal venography. Here we report a case of renal vein thrombosis with nephrotic syndrome which successfully managed with oral anticoagulants and reviewed literatures.

Background:Insulin dependent diabetes mellitus(IDDM) is known to be a disease characterized by a deficiency of insulin caused by destruction of the pancreatic beta-cells. It has been suggested that the clinical and immunological characteristics of IDDM in Korean are different from those of Caucasian. This study was undertaken to investigate the clinical characteristics and the prevalence of autoimmune markers in type I diabetic children and their prediabetic siblings in Korea. METHODS:Insulin autoantibody(IAA), antiglutamic acid decarboxylase(Anti-GAD) antibody, thyroid autoantibodies such as antithyroid antibody(ATA) and antimicrosomal antibody(AMA), and rheumatoid facter(RF) in 54 type I diabetic children have been measured. Diabetic autoimmune antibodies were also measured in 48 siblings. RESULTS: 1)Clinical characteristics of type I diabetic children were that age of onset was 8.6+/-4.4 years, duration of diabetes was 4.1+/-3.3 years. C-peptide at onset of diabetes was fasting 0.7+/-0.5ng/ml, and postprandial 1.2+/-0.5ng/ml, and HbA1c was 12.5+/-4.3%. 2)The positivity of IAA and anti-GAD antibody of type I diabetic children was 74% and 50% respectively. ATA and AMA positivity of type I diabetic children was 3.7% and 5.6%. however RF was not detected at all. Among the diabetic siblings, 48 persons for anti-GAD antibody, 21 for IAA, 27 for ICA were measured but 1 case was positive for IAA. 3)Clinical characteristics of type I diabetic children were not specific different between IAA and anti-GAD antibody positivity. But the mean age of onset of type I diabetic children was younger in case of both positivity of IAA and anti-GAD antibody than both negativity(7.8 vs 11.4 years old, P<0.05). 4)A case in whose brothers are diagnosed as IDDM has shown that autoantibody of elder brother was positive in both IAA and anti-GAD antibody, and younger brother was also strongly positive in IAA. Another case in whose sisters were IDDM, has shown that, while elder sister was positive in IAA, younger sister strongly positive in both IAA and anti-GAD antibody. 5)In a case of identical twin brother, the elder is type I diabetic child and the younger is normal, elder brother's onset of age was 6 years and 8 months old, and titer of anti-GAD antibody was measured as strong positive. Both ICA and anti- GAD antibody were negative in normal younger brother. First phase insulin release in IV GTT and the insulin levels in oral GTT showed reduction from the normal level in normal brother, and repeat check up showed normal ranges but on-going study is needed under observation. CONCLUSION: The prevalence of autoantibody positivity of type I diabetic children of Korea in this study were IAA 74%, and anti-GAD antibody 50%. Cases with both IAA and anti-GAD antibody positive were shown to be earlier onset. Though titers of auto-antibody in IDDM twins, brothers and sisters were strongly positive, auto-antibodies in siblings of IDDM patients were detected only one case with IAA positive(0.47%). We suggest that the pathogenesis of IDDM in Korean is different from foreign countries in terms of prevalence of autoimmune antibodies and more numbers of diabetic siblings should be tested for further study.

A retrospective study was made of 10 consecutive patients who underwent mandibular reconstruction with PCBM from December 1994 to July 1996. Free autogenous iliac bone in the from of particulate cancellous bone and marrow was densely packed into the crib that was adapted to bridge the mandibular discontinuity defect. Frozen-treated autogenous mandibular bone, splitted autogenous rib, and titanium mesh(Dumbach, Leibinger) were used as cribs carrying the PCBM. All ten cases underwent successful healing with the formation of a continuous bony union with the remaining mandible. The rate of resorption was assessed by sequential panoramic radiographs. The mean horizontal dimension of the madibular defects was 44mm and the mean vertical dimension of the reconstructed segments was 23mm. The bony height of the reconstructed segments retained about 90% of the bony height of over a 1-year period. We confirmed that PCBM grafts were the most successful and predictable grafts in mandibular discontinuity reconstruction.

We studied 24 cases of cutaneous T-cell lymphomas and six cases of benign lymphoproliferative diseases of the skin (2 Jessner's lymphocytic infiltration, 2 pseudolymphoma, 2 lymphomatoid papulosis) for the presence of Epstein-Barr Virus(EBV) RNA, using the in situ hybridization(ISH) method. Among the 24 cases of cutaneous T-cell lymphomas (CTCL), 18 cases including 12 cases of mycosis fungoides(MF) were primary CTCL, and the other 6 cases were secondary CTCL. The ISH study demonstrated a positive reaction for EBER probe in 6 out of the 24 cases(25%) of CTCL, and a negative reaction for BHLF nuclear RNA probe in all the cases studied. Double-labelling immunohistochemistry/ISH studies revealed that the EBV positive cells were CD45RO positive and CD20 negative. EBV genome was not demonstrated in any benign lymphoproliferative diseases of the skin. Among the EBER positive cases, none of the 12 cases of MF demonstrated EBER signals, and 6 out of the 12(50%) cases of CTCL were positive for EBER probe. In conclusion, latent infection of EBV may play a role in the development of non-mycosis fungoides T-cell lymphomas involving the skin.

To evaluate the relationships among the c-erbB-2 oncogene expression, DNA ploidy and other prognostic factors, an immunohistochemical study of the c-erbB-2 oncogene product and flow cytometric analysis of DNA ploidy were performed in paraffin sections of 42 cases of ovarian carcinomas. The results were as follows: 1) The positive reaction for c-erbB-2 oncogene product was observed mainly along the cytoplasmic membrane, and occasionally within the cytoplasm of the tumor cells. 2) Overall the positivity of c-erbB-2 oncogene expression was 45.2% of the ovarian carcinomas. By the histological types, the positivity was 35.7% in serous carcinoma, 80.0% in mucinous carcinoma, and 45.2% in endometrioid carcinoma; by the degree of differentiation, 57.1% in well differentiated carcinoma, 40.0% in moderately differentiated, and 27.3% in poorly differentiated; by the nuclear grading, 58.3% in grade I, 52.6% in grade II, and 18.2 % in grade III; and by the clinical staging, 57.1% in stage I, 42.8% in stage II, and 35.0% in stage III. The expression of the c-erbB-2 oncogene in the ovarian carcinomas was higher in the tumors of good differentiation, of the lower nuclear grade and of the lower clinical stage. 3) The incidence of DNA aneuploidy in the cases positive for the c-erbB-2 oncogene expression(47.3%) was higher than that in the negative cases(31.4%). From the above results, therefore, it is suggested that the c-erbB-2 oncogene may be involved in the early stage of ovarian carcinogenesis. Also suggested is that ovarian carcinomas positive for the c-erbB-2 oncogene in the early stages may have higher probability of having a DNA aneuploid cell line during the progress of the tumors.

Dermatitis herpetiformis is a chronic, intensely itchy, papulovesicular skin disorder of unknown cause, which is usually symmetrically distributed on extensor surface. Most patients have an associated gluten-sensitive enteropathy which is usually asymptornatic. We report six cases of dermatitis herpetiformis diagnosed by direct immunofluorescence studies. The patients have had characteristic features of dennatitis herpetiformis, such as vesicles, erythernatous papules, urticaria-like plaques, and hypopigmentation or hyperpigmentation, dispersed on the neck, back, and arms. None of the patients had subjective symptoms associated with gluten-sensitive enteropathy. Clinicians should be aware of the clinical features of this disease to avoid possible misdiagnosis, and to provide better therspeutic approaches in time.
