S.I. of TCSA PCH (group B) and musk ambrette PCH (group D) were respectively g3 49% and 75.00 S.I. of group A and B, which were only challenged with TCSA and musk ambrette respectively without prior sensitization, were 33, 33% and 27. 78%. These data indicated the TCSA PCH (group B) was experimentally produced in guinea pigs when it compared to musk ambrette PCH (group D) and controls (group A and C) (Table 1). However, S.I. of TCSA PCH was somewhat lower than index of musk ambrette PCH.

A clinical evaluation has been undertaken of 41 patients with urethral stricture who have been treated with visual urethrotomy in the Department of Urology, Seoul National University Hospital during 3 years periods from 1983 to 1985. The over all success rate was 54%. The results were unrelated to the sites of the lesion, the causes of the stricture and the durations of the catheter drainage. However, the results of the obliterated strictures (12.5%) are more poor than the non-obliterated strictures (64%), and patients with nonobliterated stricture less than 2cm long had the best results (22%). The overall morbidity rate was 20%, six cases of false way, one case of incontinence, one case of penile hematoma. Twenty seven cases were followed up over 6 months and its success rate showed 44.4%.

Subperiosteal Ganglion is a rare cystic lession, although ganglions are frequently found in close proximities to joints and tendon sheaths. It is characterized by a thin-walled cyst containing tenacious mucoid fluid and by the pedicle attached to periosteum. This report describes a middle-aged man with a subperiosteal ganglion which occured beneath the periosteam of the tibia. Presenting symptoms were pain and circumscribed swelling over the anteromedial aspect of the right proximal tibia.

Fetal teratomas rarely complicate pregnancy,having an incidance of only 20,000:1 to 40,000:1 of live births. Overthere, cervical teratomas are rare and accounts for only 5.5% of all neonatal teratomas. We have experienced a large cervical immature teratoma and present this case with a brief review of literatures.

PURPOSE: We conducted a phase II study in previously untreated patients with unresectable stage IIIB or IV non-small cell lung cancer to evaluate the response rate and toxicity of the combination chemotherapy regimen of etoposide, ifosfamide and cisplatin. MATERIALS AND METHODS: From September 1993 to December 1996, twenty patients with advanced non-small cell lung cancer (stage IIIB 5 and IV 15) (squamous cell 8, adeno- carcinoma 12), were enrolled in this study. There were 13 (65%) males and 7 (35%) females, and median age of patients were 56 years (range: 34~66). Eighteen patients had performance status (ECOG) 0~1, two patients had performance status 2. Treatment was consisted of cisplatin (20 mg/m2 i.v., day 1~4), VP-16 (etoposide) (75 mg/m2 i.v., day 1~4), ifosfamide (1000 mg/m2 i.v., day 1~4) with mesna. This treatment was repeated every four weeks. RESULTS: The overall response rate was 25%. Complete response rate was 5% (1/20) and partial response rate was 20% (4/20). The median cycle of response was 4 (2~6) cycles. The median overall survival time was 28 weeks (9~98 weeks). The median time to progression was 10 weeks (3~50 weeks). Toxicities were evaluated by WHO criteria. Toxicity > GradeIII included: leukopenia 1.6%, thrombocytopenia 3.2%, nausea and vomiting 15%, alopecia 30%, stomatitis 10%. These toxicities were tolerable and reversible. CONCLUSION: VIP regimen was not superior to previous regimens for advanced non-small all lung cancer, and the toxicities were tolerable.

Lichen planus is a common, usually intensely pruritic papulosquamous dermatosis with unknown etiology, which may involve the skin, mucous membranes, hair follicles, and nails. Its lesions are usually a localized form but generalized ones are an unusual presentation of lichen planus. We report herein three cases of generalized lichen planus in one male and two female patients, which was diagnosed on clinical and histopathological examinations in all cases.

20-year-old patient presented with the episodes of generalized hyperkeratotic lesions with bullae since her early life, without family history. Histopathological examination by light and electron microscopes showed the characteristic features of epidermolytic hyperkeratosis. Primarily, she failed to respond to the treatment with propylene glycol. Vitamine A palmitate(A-Mulsin) per os appears to be a beneficial remedy for epidermolytic hyperkeratosis, although its availability is limited due to the side effects on a long term therapy. Repeated biopsies in the normal appearing lesions 2 months after treatment of vitarnin .A palmitate showed a substantial reduction of the horny layer on the light microscope and orderly arrangement of the tonofilaments, and properly formed keratohyaline granules on EM, but the underlying disorder of keratinization remained unchanged. Treattnent of 2 months with vitamin A was interrupted by side effects of nasal bleealing, chelitis and xerosis.

Lichen nitidus, characterized by its typical clinical and histopathologic findings, is an uncomrnon chronic dermatosis of unknowned etiology. The distribution of this disease is most often localized, but in some cases it may becorne generalized. Some authors suggested that lichen nitidus is a variant of lichen planus in terms of its coincidence, ultrastructural and immunophenot,ypic studies. We report herein a case of lichen nitidus which presents dark brown linear, grouped, or confluent papules on the face, cheat, and upper extremities, accompanying with the histopathologic findings of pigmentary incontirence in the portion of claw clutching a ball appearance. This report suggests that lichen nitidus shows hyperpigmentation clinically and could be one of the dermatoses which exhibit pigmentavy incontinence in a histopathologic study.

OBJECTIVE: Peripartum emergency cesarean hysterectomy of 28 cases at our hospital for 10years were reviewed that the clinical indication, history, and annual incidence change. METHODS: A retrospective descriptive analysis from January, 1988 to December, 1997 was carried out. RESULTS: There were 28 cases of emergency cesarean hysterectomy identified during this period among total 24, 689 deliveries. The annual incidence of emergency cesarean hysterectomy was significantly declined statistically(p<0.005). Cesarean hysterectomy was performed in 20 of 6, 671 cesarean section(0.30%) and in 8 of 18, 018 vaginal deliveries(0.04%), so more frequently after cesarean section than vaginal delivery. The cesarean hysterectomy rate was more frequent in multiparous women(0, 22%) than in nulliparous women(0, 02%). The most common indication of cesarean hysterectomy was 13 cases of uterine atony(46%), followed by 5 cases uterine rupture(18%), 5 cases of placenta previa with placenta accreta(18%), 3 cases of placenta previa(11%), 2 cases of uterine myoma(7%). No significant difference in length of operating time, amount of blood loss and operative complications were found between total abdominal hysterectomy and subtotal hysterectomy. The all patient who had cesarean hysterectomy recieved from 1200ml to 15840ml of blood transfusion with a mean of 3673ml. In aspect of fetal outcome, 3 cases of FDIU(Fetal death in utero) in uterine rupture and 1 case of stillbirth in preterm were found. The maternal complications were wound disruption, DIC, wound hematoma, ureter injury, vaginal stump bleeding, UTI(Urinary tract infection) and retroperitoneal bleeding, CONCLUSION: We conclude that the incidence of emergency cesarean hysterectomy declined with prediction of antenatal risk factor, preparing of sufficient fresh blood, prophylactic antibiotics, vigorous uterotonics and close observation after delivery.

Journal of the Korean Ophthalmological Society 2015;56(9):1371-1376
PURPOSE: To investigate the effect of gas tamponade with vitrectomy for lamellar macular hole. METHODS: This study included 18 eyes of 18 patients with lamellar macular hole who reported visual acuity loss or distorted vision. All patients underwent vitrectomy, epiretinal membrane removal and internal limiting membrane peeling. Intravitreal gas tamponade was performed only in 8 eyes of 8 patients. The patients were divided into 2 groups: 8 eyes in the gas tamponade with vitrectomy group and 10 eyes that did not receive gas tamponade in the control group. The best-corrected visual acuity (BCVA) and appearance based on optical coherence tomography (OCT) were obtained retrospectively. RESULTS: Epiretinal membranes were observed in all cases. Average visual acuity of the gas tamponade group improved from log MAR 0.50 +/- 0.24 to log MAR 0.25 +/- 0.14 (p = 0.041). In the control group, average visual acuity improved from log MAR 0.53 +/- 0.36 to log MAR 0.32 +/- 0.28 (p = 0.041), however, no significant difference was observed in visual acuity between the 2 groups (p = 0.584). Anatomical closure or normalized foveal contour after surgery was confirmed in 6 of 8 eyes in the gas tamponade group and in 7 of 10 eyes in the control group. No significant difference between the 2 groups was observed (p = 1.00). CONCLUSIONS: Gas tamponade combined with vitrectomy for lamellar macular hole did not affect postoperative anatomical and functional recovery.
