Nevus sebaceus of Jadassohn is a hamartoma of the skin with the potential to develop benign and malignant neoplasms. This case was characterixed by multiple basal cell epitheliomas, clinically one reddish nodule and multiple pigmented papules, arising in the nevus sebaceus. Histologically, epithelial papillomatous hyperplasia and high-positioned hyperplastic sebaceous glands were found, and tumor nests consisting of basaloid cells with peripheral palisading arrangements were mainly situated in the upper dermis without significant infiltrative growth. We report a rare case of nevus sebaceus with multiple basal cell epitheliomas in the right cheek of a 49-year-old woman.

Vasectomy is the most popular method of birth control in Korea. Because of changing views about family life, increasing prevalence of divorce and remarriage, desire for more children, and fear of child death. a large number of men now. are requesting reversal or vasectomy. Between March 1987 and September 1991 we performed vasovasostomy using modified one-layer technique with optical loupe magnification in 58 patients who had underwent vasectomy for family planning. Of these 58 patients, 46 patients could be followed up. Rates of patency and pregnancy varied depending on the interval from vasectomy until its reversal. Patients whose vasectomies had been performed less than 5 years had a 95.0% patency rate and a pregnancy rate of 72.0%. Patients who had an obstructive interval of 5 to 10 years had a 85.7% patency rate and a pregnancy rate of 50.0%. Beyond 10 years, there was a 33.3% patency rate and a pregnancy rate of 0.0%. The overall success rate was 86.5% for patency and 58.7% for pregnancy. Since the modified one-layer vasovasostomy is easier, faster, and less expensive, this technique deserves further clinical experience and evaluation.

A comparative analysis was made in 115 cases of TUR and 38 cases of open surgery in benign prostatic hyperplasia from March 1982 to December 1988.The results were as follows: The mean duration of operation was 84 min in TUR and 112 min in open surgery. The mean weight of resected tissues was 15.9em in TUR and 34.8gm in open surgery. The number of patients who needed transfusion were 74 of 115 in TUR(64%) and 35 of 38 in open surgery. Mean periods of postoperative hopitalization wee 9.1 days in TUR and 15.3 days in open surgery. Intraoperative complications were massive bleeding(5.2%), perforation of prostatic capsule(2.6%), hyponatremia(0.9%) in TUR and massive bleeding( 10.5%) in open surgery. Postoperative complications were unable to void, bleeding, incontinence, epididymitis, pyelonephritis and urethral stricture in TUR and bleeding. incontinence, epididymitis, pyelonephritis, vesicocutaneous fistula and wound infection in open surgery. Total complication rate was 26.1% in TUR and 28.9% in open surgery.

Chronic prostatitis is very common urologic disease, but its symptomatology is varied and nondiagnostic. We have performed transrectal ultrasonography in 66 cases of patients who were impressed as chronic prostatitis based upon their symptoms and physical findings for the purpose of evaluating the role of transrectal ultrasonography in the diagnosis of chronic prostatitis.The results were summarized as follows;1. In microscopic findings of prostatic secretion, 20 cases(Group I ) showed W.B.C. less than 10/H.P.F and 16 cases(Group II ) showed W.B.C. more than 10/H.P.F. 2. The abnormal findings of transrectal sonography in chronic prostatitis were as follows; 1) Echolucent zones; 22 cases(39%) 2) Calcification; 37 cases( 56%). 3) Heterogeneous echo; 40 cases( 61%). 4) Capsular irregularity or thickening; 35 cases( 50%) 5) Periurethral zone irregularity, 28 cases(42%). 6) Echolucent 'halo' sign; 33 cases( 50%). 7) Seminal vesicle or ejaculatory duct abnormality; 18 cases(27%). 3. Among above findings, l), 2), 3), 4), 5) findings were more frequently detected in Group II than in Group I (p<0.05). 4. The combined detection rate of l), 2), 3), 4), 5) findings were statistically higher in Group II than in Group I (p<0.05). 5. High grade l), 2), 3), 4), 5) findings were more frequently detected in Group II than in Group I (p<0.05). Our results suggest that although transrectal ultrasonography is not diagnostic for chronic prostatitis, it may be an useful adjuvant diagnostic modality to laboratory studies in the evaluation of chronic prostatitis.

Six patients with macular hole and retinal detachment and no visible vitreoretinal connection examined by slitlamp and 3-mirror contact lens were treated by two methods. In two patients with relatively localized retinal detachment in central fundus, 0.7ml or more of pure SF6 gas was injected into vitreous cavity by 27 gauge needle after paracentesis was done because of keeping the large space of gas injection as preventmg the increase of lOP. In the remained 4 patients, 1.2ml or more of pure SF6 gas was injected into vitreous cavity after the subretinal fluid was released externally, and then paracentesis was done because of preventing the increase of lOP. After operation, all patients were placed in prone position for 6 hours or more in a day. In 5 of 6 patients, the retina remained attached duing more than 6 months. Even if 2 with posterior staphyloma in 6 patients were treated with two or more operations, 1 patient was failed. Although visual improvement at 6 months after operation was limited due to macular degeneration, the visual acuity were above 0.05 in 3 patients. This operation is simple and safe and not damaged en macula. This procedure is good surgical method in patients with retinal detachment wirh macular hole but without other breaks or visible vitreous adhesion or posterior staphyloma.

The vitrectomy and silicone oil injection has been used occasionally for the advertent retinal detachment, but the silicone oil placement within the vitreous cavity may cause the complications in such as band keratopathy, emulsification of silicone oil, iritis and glaucoma, etc. Especially, in the phakic eyes, the silicone oil may enter the anterior chamber in the form of a suspension of fine globules resembling an inverted hypopyon and it is called the hyperoleon. The authors observed a case of hyperoleon 4 months after surgery, reporting it with the review of literatures.
