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.

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.

Syringocystadenoma papilliferum is s rare tumor of disputed origin that was first reorted by peterson in 1892. Theclinical features of syringocystadenoma papilliferum are not constant. It may be present at birth or develop later in life. Its appearance varies from an irregular, flat, grey or reddish area to a grey or dark brown. raised and cauliflower-like surface. Sometimes it is moist, flesh or pedunculated and occasionally a verrucous plaque, or cyst may be seen. The typical lesion occurs most frequently on the scalp, and is a hairless smooth plaque until puberty, when a nodular verrucous transformation occurs. A 39 years old male patient had egg sized (3*5cm) and yellowish red colored verrucous tumor mass on his epigastric area, which had grown up slowly for 7 years. The diagnosis of syringocysyadenoma papilliferum was confirmed by histological examination. We repoet a case of syringocystadenoma papilliferum in unusually large size on the epigastric area.

There has been much interest in the involvement of wind-up in the hyperalgesia and allodynia of chronic pain syndrome. For investigating the hehaviorml parallels of this wind-up phenomenon, it was limed to evaluate the changes of neurotransmitters(aspartate. lutamate, and taurine) in central sensitization after formalin-induced peripheral nerve injurv in the rats. The experiment was divided into two subexperiments; One was the formalin test.;and the other was microdialysis for evaluation of neurotransmitters. In formalin test (n=7), 50 microliter of 5% formalin was injected suhcutaneously in the foot dorsum of the right hind limb with a 30 G neeclle. To cluantify the formilin response. the number of spontaneous t1inches was counted at 1-2 minutes and 5-6 minutes and at 5 minutes intervals during the period 10- 60 minutes after formalin injeclion. In microdialysis study. the experimental animals were divided randomly into two groups. In experimentl group (n=10). the microdialysis catheter was perfused with artificial cerehrospinal fluid by 3 microliter/min for one hour. Then. the two beseline dialysis samples were collected and 50 microliter of 5% formalin was injected .iuhcutaneously in thc plantar surface of the right hind paw with a 30 G needle. Three 10 minutes dialysate samples were collected after formalin injection. In control group(n=10), the normal saline instead of formalin was used. The results were as followed: In formalin test, there was a biphasic pattern of flinchine after formalin injection. The peak in phase I was shown at 2 minutes after formalin injection. The second peak was shown at 35 minutes alter formalin injection during phase II. In microdialysis study, thcre were statistically significant increascs of aspartate and lutamate concentrations, excitatory neuro transmitters, during the first 10 minutes after formalin injection. After lhen, all values of these neurotransmitters were rcturned to baseline values. The concentrations of taurine, an inhihitory neurotransmitter, was shown a tendency of an increase after formalin injection but, it was not statistically significant. From these results, it secms that the excitatory amino acid ncurotransmitter may partly play a role to triqer the central sensitization after peripheral nerve injury.
