BACKGROUND: In epidermolysis bullosa acquisita, it has been recognized that there exists heterogeneity in the clinical and serologic/immunopathologic features. OBJECTIVE: We examined patients with epidermolysis bullosa acquisita to see if there were any associated clinical and serological features which may predict disease activity or prognosis in the disease. METHODS: Clinical and some serologic features were compared. between 2 groups of patients with epidermolysis bullosa acquisita; one with complete remission of the symptoms and signs of the disease for more than 2 years and the other group with persistent disease activities of longer than 5 years.

The anatomical structure of vermiform appendix was studied for 124 Korean adult cadavers and the articles were reviewed with special reference to its position and length. The results are as follows ; 1. On the frequency of positional types based on Wakeley (1933), postileal type was recorded most frequently (37.7%) and retrocecal type was found in 19.7% of cases, showing the difference from other ethnic groups whose most frequent position was retrocecal or pelvic type. 2. In the direction of appendix in relation to the clock, the direction between 1 and 3 o'clock was most frequently found. 3. Appendix of fixed form was found in 22.1% of cases, that of free form 77.9%. In free form, postileal type was found most frequently, but retrocecal type was met most frequently in fixed form. 4. The length of appendix was 5.95±1.64 cm (male ; 6.14±1.67 cm ; female 5.59±1.51 cm). Neither significant difference between sex nor positional type was noted. 5. Positions of appendix are seemed to be set up during fetal stage. The Ethnic variation in the positions of appendix is thought to be determined by inherited physical anthropological factor, not by postnatal one.

Postoperative colonoscopy is an effective tool for management of colonic adenomas. Authors analyzed the pattern of colonic adenomas detected during follow-up colonoscopy after colorectal cancer surgery and evaluated the characteristics of adenornas, risk groups, and effective fo1low-up schedule. Study group were 222 patients and colonoscopy was performed 389 times. Patterns of adenornas were analyzed by variables as age, sex, preoperative serum CEA level, location of primary colorectal cancer, Borrmann type, Duke's stage, histologic differentiation, DNA ploidy, recurrence and histology. Metachronous adenomas were detected in 79 patients(35.6%) and both metachronous and syachronous adenomas were observed in 29 cases(13.1%). High risk variables for adenomas were male, old age and presence of synchronous adenoma. There were 2 patients with maligant change of adenomas. Yearly follow-up by complete colonoscopy over 3 years or more is recommended and follow-up interval should be shortened in the high risk groups.

OBJECTIVE: Identification of the regulatory mechanism for arrest and initiation of primordial follicular growth is crucial for female fertility. Previously, we found 15 expressed sequence tags (ESTs) that were specifically abundant in the day-5-subtracted cDNA library and that the B357 clone was novel. The present study was conducted to obtain the whole sequence of the novel gene including B357 and to characterize its mRNA and protein expression in mouse ovary and testis. METHODS: The extended sequence of the 2,965-bp cDNA fragment for the clone B357 was named 5-day-ovary-specific gene-1 (5DOS1) and submitted to GenBank (accession number AY751521). Expression of 5DOS1 was characterized in both female and male gonads at various developmental stages by Northern blotting, real-time RT-PCR, in situ hybridization, Western blotting, and immunohistochemistry. RESULTS: The 5DOS1 transcript was highly expressed in the adult testis, brain, and muscle as compared to the other tissues. In the ovary, the 5DOS1 transcript was detected in all oocytes from primordial to antral follicles, and highly expressed at day 5 after birth and decreased thereafter. In contrast, expression of 5DOS1 showed a gradual increase during testicular development and its expression was limited to various stages of male germ cells except spermatogonia. CONCLUSIONS: This is the first report on the expression and characterization of the 5DOS1 gene in the mouse gonads. Further functional analysis of the 5DOS1 protein will be required to predict its role in gametogenesis.

Primary cutaneous monomorphous lymphoma is rare compared to the more usual involvement of skin secondary to internal monomorphous lymphoma. The histopathological diagnosis of the primary cutaneous monomorphous lymbhoma (PCML) requires differentiation from cutaneous lymphoid hyperplasia. The authors observed 3 cases of PCML. Case 1 was 21 year-old woman, who had an initial lesion on her left arm. Histopathologically it was diagnosed as poorly differentiated. lymphocytic lymphoma and was treated by surgical excision. Six months after onset she developed new lesions on her skin elsewhere, histopathologically diagnosed as well differentiated lymphocytic lymphoma. She died of infiltration of the bone marrow 19 months after the initial onset, even though combination of radiotherapy and chemotherapy resulted in clinical improvernent. Case 2 was a 70 year-old woman having an unusual cutaneous manifestation of an adult palm sized ulcerative, indurated tumor on her right forearm, histopathologically diagnosed as histiocytic lymphoma. There was no evidence of extracutaneous in volvement except right axillary lymphadenopathy. Case 3 was 72 year-old man, who had a clinical manifestation to that of case 2, histopathologically diagnosed as histiocytic lymphoma and received radiotherapy with good improvement. The patient did not show any evidence of extracutaneous involvement five months after the onset.

PURPOSE: To evaluate intrahepatic nodular lesions detected on CTAP but not on conventional contrast CT in regard to its relationship with satellite nodules or borderline malignancies. MATERIALS AND METHODS: From June 1991 to March 1994, CTAP was undertaken in 132 cases with confirmed hepatocellular carcinoma(HCC), of which 35 cases having 82 lesions were suitable for analysis(excluding the cases which had no follow-up studies, showed segmental abnormal portal perfusion, no additional lesions and, or inumerable lesions). The CTAP findings were compared with those on artery dominant imaging studies (angiography, DSA, bolus dynamic CT, arterial CT, Lipiodol CT) taken during the same period(to confirm the presence of lesions) and the findings on follow-up imaging studies(to assess the developemerit of malignancy). RESULTS: Arterial vascularity was identified in 35 of 82 lesions(42.7%) on arterial dominant imaging studies. Developement into malignancy was identified on follow-up imaging studies in 25 of remained 47 lesions(53.2%). CONCLUSION: The total positive predictive value of nodules on CTAP was 73.2%(35+25/82), but the predictive value for HCC by follow-up only was 53.2%. Given'the difficulties in detecting intranodular arterial flow and the short follow-up duration in many patients, the actual positive value might be higher.
