A clinical observation was made on 136 cases of benign prostatic hyperplasia, admitted to the department of Urology, National Medical Center during the period from January 1970 to December 1981. The result are summarized as follows: 1. Incidence of benign prostatic hyperplasia was 6.1% to 2,226 total in-patients, 10.3% to 1,315 male in-patients and 23.3% to male in-patients 50 years old or more. 2. Majority of cases Was found in 7Ih and 8th decades (78.6%) with mean age of 68.9 years old. 3. Seventy one patients (52.2%) suffered from urinary retention prior to admission. 4. Mean interval elapsed from initial symptoms to visit was 26.8 months. 5. Method of operative treatment included 68 suprapubic prostatectomy, 10 retropubic prostatectomy and 5 T.U.R. 6. Mean weight of removed adenoma was 42.6 gm in suprapubic prostatectomy and 34.7 gm in retropubic prostatectomy. 7. Mean amount of blood transfusion was 700 ml in suprapubic prostatectomy, and 224 ml in retropubic prostatectomy. 8. Mean period of catheter drainage was 11.9 days in suprapubic prostatect0my, 13.3 days in retropubic prostatectomy and 5.4 days in T.U.R. 9. Mean duration of postoperative hospitalization was 17.8 days in suprapubic prostatectomy, 15.8 days in retropubic prostatectomy and 8 days in T.U.R. 10. Postoperative complications were delayed healing with suprapubic fistula, wound infection, prolonged bleeding 14 days or more, temporary incontinence, epididymitis, unable to void and pneumonia, in suprapubic prostatectomy and prolonged bleeding, wound infection, temporary incontinence and unable to void in retropubic prostatectomy.

A Malignant Schwannoma is a relatively rare primary nerve sheath tumor arises from Sehwann cells of the peripheral nerves. This tumor is frequently associated with von Recklinghausens disease. A high percentage of patients experience local recurrence even after radical surgical excision, and eventual pulmonary metastases via the intraneural and hematogenous routes. The treatment of choice is radical excision or amputation. Results of treatment with radiation and chemotherapy have been disappointing. The authors have experienced two cases of Malignant Schwannoma, one of which was located in the median nerve of the palm, the other in the ulnar nerve of the arm, but neither were associated with von Recklinghausens disease.

BACKGROUND: The reference list is an important part of a scientific article. To be useful it must be accurate. OBJECTIVE: The purpose of this study was to evaluate the accuracy of reference citations in the Korean Journal of Dermatology and the Annals of Dermatology. METHODS: We randomly selected 200 references (100 references from Korean language journals and 100 references from foreign language journals) from the Korean Journal of Dermatology and 100 references from the Annals of Dermatology and checked them against the .original articles. RESULTS: The overall rate of citation error was 32%, and errors in the title and author names of the citation were common, each occurring in about two fifths of the citation errors. CONCLUSION: This study shows that the rate of citation errors is unacceptably high in the Korean Journal of Dermatology and the Annals of Dermatology, which significantly diminishes the value of the reference list.

Dysregulation of TGF-beta that is a modulator of cell growth and differentiation can result in uncontrolled growth and tumor formation. Monitoring these pattern of genes and protein expression during tumor development will provide a basis for understanding normal growth and distortion of osteochondrogenesis. Our comparative studies on the experssion of TGF-beta protein indicate that TGF-beta may primarily be a regulator of epithelial differentiation during tooth development (between 4 weeks and 40 gestational weeks) and tumorigenesis of odontogenic neoplasm (ameloblastoma). In early human tooth germ (cap/early bell stage) TGF-beta protein was found in the epithelial dentallamina and enamel orgen. TGF-beta experessions were seen in inner and outer dental epithelium during bell stage. During enamel and cementum appositional stage, TGF-beta expression shifted from the ameloblast to the odontoblast. In eruption stage, TGF-beta expressions look like moderate positive pattern in odontoblast and rare pattern in enamel, dentin and cementum. TGF-beta expressions of follicular and plexiform amelobalstoma are moderate positive reaction in ectodermal tumor components and mild positive in vessels of stroma tissue. In acanthomatous type, TGF-beta expression was shown severely positive finding in stellate reticulum cell. TGF-beta expressions were noted moderate reaction in margin of tumor epithelium and stellate reticulum cell of granular ameloblastoma. In unicystic ameloblastoma, TGF-beta expression was rare feature in cystic luminal epithelium. With these result, I should be suggested that TGF-beta may play an important role in epithelial-mesenchymal interactions in human tooth morphogenesis and development of odontogenic epithelial tumors.
