1.Experience of Double J Stents on Urinary Diversion.
Korean Journal of Urology 1987;28(6):881-886
Double J stents have been advocated for drainage or splintage of the ureter. Fifty-four attempts at double J stent insertion were made in 46 patients. In 93% attempts the stent was satisfactorily placed. Their use in adjunct to urologic and gynecologic surgery, percutaneous nephrolithotomy and ureterorenoscopy has been encouraging but poor results have been obtained in patients with ureteral obstruction due to tuberculosis and malignancy.

Neoplasms showing both carcinomatous and sarcomatous features are well established, and have been reported in practically every organ where carcinoma can occur. But the difference in terminology and difficulties in histopathologic interpretation have hampered adequate understanding of these neoplasms. We report a case of carcinosarcoma in the recurrent form of serous cystadenocarcinoma of the ovary. The patient was a 64-year-old female who underwent total hysterectomy and bilateral salpingoophorectomy three years ago, due to perforated papillary serous cysta denocarcinoma of the right ovary. Recurrent pelvic masses contained both carcinomatous and sarcomatous components. Morphological transition between carcinomatous and sarcomatous components, and epithelial characteristics in the sarcomatous component by immunohistochemistry were recognized. We postulate the histopathogenetic mechanism based on the phenotypic conversion of carcinoma into sarcoma in the carcinosarcoma.

A case of an ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma is reported. The patient was a 46-year-old female with a right ovarian cystic mass and underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The patient died of the disease in five months. Macroscopically, the right ovarian cyst wall contained numerous well-demarcated mural nodules. Histologically, the cysts were mucinous cystadenocarcinoma, and the nodules were composed of sarcoma-like spindle and polygonal cells with atypia and numerous mitoses. Spindle cells in the mural nodule showed epithelial characteristics by electron microscopy and immunohistochemistry. This case supports an epithelial origin of the mural nodule of anaplastic carcinoma in ovarian mucinous tumors.

In transtrochanteric rotational osteotomy to treat osteonecrosis of the femoral head, the necrotic superior anterior femoral head is rotated anteriorly around the longitudinal neck axis so that the weight bearing force is transferred to the intact posterior surface. The ratio of transposed intact articular surface of the femoral head to the weight-bearing surface of the acetabulum on postoperative anteroposterior view of the hip roentgenograph is the most important indicator of the prognosis. During the period from December 1992 to June 1994, we treated 31 hips in 28 patients who were indicated for the anterior rotational osteotomy among the patients of osteoncrosis of the femoral head. Among the patients, male were 27 and female was one. Age distribution was from 13 to 62 years old and mean age was 44.3. According to the Ficat and Arlet classification, II A was most in number as 16 II B was 7 and III was 8. As their etiolgic factors, alcohol was most in number as 18, steroid was 3, idiopathic was 5 and trauma was 2. The mean rate of the intact area of the posterior part of the femoral head to the total articular surface on the preoperative lateral view of the hip roentgenograph was 41.8%. The mean ratio of transposed intact articular surface of the femoral head to the weight bearing surface of the acetabulum was 53.8% Fixation devices were screws or dynamic hip screw.

Endoscopic retrograde cholangiopancreatography(ERCP) procedures are more difficult in patients who have undergone partial gastrectomy with Billroth II anastomosis. Because its altered anatomical relationship. the endoscopist is presented with additional problems: (i) Dfficulties in entering the afferent loop, depending on the surgical techiques used. (ii) The endoscope may be too sort to reach the papillary region unless the loops are suecessfully straightened out. (iii) Difficulties in passing the ligament of Treitz, especially in patients with Braun's anastomosis, (iv) Problems in cannulating the papilla and especially the common bile duct from a reversed position. (v) Problems in carrying out a papillotomy in a correct position. We attempted endoscopic sphincterotomy in 3 opatients previously subjected to gastrectomy with needle knife, and succeeded in 2 of them. In the two patients, successful billary drainage was achieved. And one patients with Billroth II gastrectomy, presented with CBD stone and cholangit, was successfully treated with endoscopic stone retriveial. The patient with a Billroth-II operation may unergo endscopic diagnostic as well as therapeutic procedures with a high rate of success, and can be suitable candidates for ERCP and endoscopic sphincterotomy

A case of diffuse malignant mesothelioma of peritoneum which was difficult to distinguish from metastatic anaplastic carcinoma or malignant melanoma was presented. The patient was a 50 year-old woman and complained of an abdominal pain and ascites for 20 days. Histologically, the tumor cells showed highly anaplastic appearance with sheet-like arrangement without any papillary or tubular structure. They stained Positive for cytokeratin and vimentin and negative for CEA, S-100 protein and melanoma associated antigen. A few cells within the tumor showed Positive reactivity to desmin. Ultrastructurally, the tumor cells had characteristic findings of mesothelioma such as long, exuberant, wavy microvilli with 10 to 12 of length/diameter ratio. The patient died 3 months after the diagnosis in spite of intraperitoneal chemotherapy.

Human papillomavirus (HPV) 16/18 is a causative agent of uterine cervical carcinoma. HPV 16/18 can alter cell cycle regulation through apoptosis. Bcl-2 is an important regulatory gene of apoptosis. A study was done to evaluate the relation between HPV 16/18 and bcl-2 and apoptosis in 21 cases of carcinoma in-situ (CIS), 5 cases of microinvasive carcinoma and 23 cases of invasive squamous cell carcinoma. HPV 16/18 was detected by hybrid capture system (HCS), bcl-2 protein by immunohistochemical method and apoptosis by using the hematoxylin-eosin stained slide. The results were as follows: Expression of the bcl-2 protein was 43% (9/21) in CIS and 26% (6/23) in invasive carcinoma. Expression of the bcl-2 protein was 42% (5/12) in CIS with HPV 16/18 infection, 44% in CIS without HPV 16/18 infection, 20% (2/10) in invasive carcinoma with HPV 16/18 infection and 31% (4/13) in invasive carcinoma without HPV 16/18 infection. Mean apoptotic index (mAI) was 3.36 in CIS, 5.23 in microinvasive and 6.25 in invasive carcinoma. mAI was 3.66 in CIS with HPV 16/18 infection, 2.86 in CIS without HPV 16/18 infection, 6.18 in invasive carcinoma with HPV 16/18 infection and 6.30 in invasive carcinoma without HPV 16/18 infection. Based on these results, we conclude that there are no correlation between HPV infection and bcl-2, and between HPV infection and apoptosis in invasive and in situ carcinoma of the uterine cervix, and apoptosis is increased according to tumor progression.

In the correction of congenital blepharoptosis, there are banked fascia lata, silicone band or rod, palmaris longus tendon, Gore-Tex, Mersilene, Supramid and etc. used for frontalis suspension. A retrospective study on the results and recurrences of 63 patients[79 eyes] who were diagnosed as congenital blepharoptosis and received frontalis suspension with Supramid Extra II(r) from Jan.1994 to Dec.1998. was done. The patients were consisted of 36 males and 27 females and the average age at the time of operation was 18 months[3.5 months~58 months]. The postoperative results were satisfactory in all the patients, yet recurrence was found in 26 patients between 4.5 months and 56 months after surgery. The results of 48 patients who could be followed up for over a year showed a 52%[25 patients] recurrence rate with a mean follow-up time of 41.3 months. The mean recurrence time was 30.7 months after operation. The use of Supramid Extra II(r) in frontalis suspension has benefit such as easy availability and favorable handling characteristics, but due to its high recurrence rate, it prompts the need for patient education and a follow-up period of over 4 years.

Journal of the Korean Ophthalmological Society 1999;40(12):3246-3252
To investigate results of treatment with essential blepharospasm, patients were evaluated by results of treatment with botulinum toxin A and myectomy operation. Seventy patients of the essential blepharospasm who received local injection of botulinum toxin or orbicularis muscle extirpative surgery were evaluated according to results and complications of the treatment modality over a 7-year period. Fifty-six patients[80%] were primarily treated with botulinum toxin and 14 patients[20%] underwent myectomy operation as the primary treatment. Of the 56 patients, 8[14.3%] were treated later with myectomy operation. In botulinum toxin treatment, the mean subjective improvement was found in 89.2% of the patients, and the mean effective durations of essential blepharospasm were 12.7 weeks. Severity and frequency grades in eyelid spasm were significantly lower after injection[P=.000]. Tearing, dry eye, and headche were the most frequent complications and ptosis was observed in 2 cases[2.0%]. In the orbicularis myectomy operation, 13 patients[59.1%] were carried out through a brow incisions, 1[4.5%] through a blepharoplasty incisions, and 8[36.4%] through both. Fourteen patients[63.6%] had acceptable control of blepharospasm throughout follow-up after the upper lid orbicularis stripping procedure alone. We believe that botulinum toxin is the treatment of first choice because of its higher acceptance rate. Surgery is reserved for botulinum toxin failure. In otherwise fit patients, myectomy is the treatment of first choice.

We investigated the effects of panretinal photocoagulation (PRP)on macular microcirculation in diabetic retinopathy. PRP using argon blue green laser was performed in 23 eyes of 15 patients with early proliferative diabetic etinopathy and very severe nonproliferative diabetic retinopathy without significant macular edema. The changes in volume, flow, velocity of macular microcirculation were measured before PRP, 1 hour, 1 day, 1 week, and 1 month following PRP, using Heidelberg Retina Flowmeter(HRF). Mean volume, flow, velocity of macular microcirculation decreased to a maximal degree 1 hour following PRP, from 14.87+/-0.40, 387.45 +/-101.40, 1.40+/-0.28(before PRP)to 12.44+/-1.39, 347. 33+/-100.39, 1.27+/-0.34(p<0.05). From 1hour to 1 month after PRP, macular microcirculation gradually increased. However, throughout this period, all parameters of macular microcirculation remained lower than pre-PRP level(p<0.05). Our study suggests that panretinal photocoagulation reduces the macular microcirculation in diabetic retinopathy.
