BACKGROUND: Flecainide is an antiarrhythmic agent that is used primarily in the treatment of cardiac arrhythmias. Some evidences also suggest that flecainide can participate in alveolar fluid clearance and inflammatory responses. This experiment was aimed to evaluate the effects of flecainide on sepsis induced acute lung injury in a rat model. METHODS: Rats were treated with subcutaneous infusion of saline or flecainide (0.1 or 0.2 mg/kg/hr) by a mini-osmotic pump. Subcutaneous infusion was started 3 hours before and continued until 8 hours after intraperitoneal injection of saline or endotoxin. Animals were sacrificed for analyses of severity of acute lung injury with wet to dry (W/D) ratio and lung injury score (LIS) in lung and inflammatory responses with level of leukocyte, polymorphonuclear neutrophils (PMNs) and inteleukin-8 (IL-8) in bronchoalveolar lavages fluid (BALF). RESULTS: Flecainide markedly improved dose dependently sepsis induced acute lung injury as analysed by W/D ratio (from 2.24 ± 0.11 to 1.76 ± 0.09, p < 0.05) and LIS (from 3 to 1, p < 0.05), and inflammatory response as determined by leukocyte (from 443 ± 127 to 229 ± 95, p < 0.05), PMNs (from 41.43 ± 17.63 to 2.43 ± 2.61, p < 0.05) and IL-8 (from 95.00 ± 15.28 to 40.00 ± 10.21, p < 0.05) in BALF. CONCLUSIONS: Flecanide improve sepsis induced acute lung injury in rats by controlling inflammatory responses.

Prior to 1988, endometrial cancer was clinically staged but there was the considerable discrepancy between clinical and aetual stage. FIGO surgical staging classification of endometrial cancer(I988) provides the advanatage of recognizing the true disease distribution and extension, and more rational treatraent can be accomplished. This retrospective study was based on a clinical review of 73 patients with endometrial carcinoma from l982 through 1991 who underwent primary surgical evaluation. A11 cases were restaged ueing the newly adopted FIGO surgical staging. The distribution of FIGO clinical staging was as follows:85 patients(89.1%) were with stage I, 5(6.9%) with stage II, 2(2.7%) with stage III and 1(l.3%) with stage IV. Surgical restaging according new FlG0 classification reveald 56(76.7%) patients with stage I, 1(1.4%) with stage II, 14(19.2%) with stage III and 2(2.7%) with stage IV. Surgery upstaged 12.3% of clinical stage I patients, In clinical stage II patients, 80.0% was doenstaged. There wes no stage changing in cliaical stage III and IV patients. The acturial survival rates for surgical stages I a, I b, I c, and III were 80.0%, 77.2%, 68.4A%, and 35.0% respectively. By using FIGO surgical staging, the initial extent of endometrial cancer can be more accurately evaluated and we may predict prognosis and survival relatively well.

Thyroid acropachy is a rare complication of Graves' disease, manifested by clubbing of the terminal phalanges, periosteal new bone formation and overlying soft tissue swelling, It may occur when the patient is hypothyroid, euthyroid or hyperthyroid. In most cases, it is a part of the syndrome, including exophthalmos and/or pretibial myxedema. The authors have experienced one case of thyroid acropachy and report with a review of the literature review. The patient a 56-year-old female with a characteristic feathery new bone formation on the medial side of the shaft of the left first metatarsal bone and overlying soft tissue swelling. However, there was no pretibial myxedema and clubbing of fingers. She was hypothyroid and treated with systemic corticosteroid for mild pain and persistent swelling. The treatment had temporarily improved the patient's condition.

BACKGROUND & AIMS: Management of ovarian carcinoma presents most commonly by surgery and subsequent platinum-based chemotherapy, but most patients will have either residual or recurrent disease. Taxol, a new antimicrotubule agent, has been indicated as a salvage measure after failure of first-line or subsequent chemotherapy. The purpose of this study is to investigate the efficacy and toxicity of Taxol used as a salvage therapy. MATERIALS & METHODS: Between January 1994 and Jun 1996, 19 patients aged 38-64 years(median 52) with ovarian carcinoma were given Taxol-containing regimen. Taxol was administered at a dose of 135mg/m2 intravenously with cisplatin or carboplatin every 3 weeks. The patients who treated with Taxol only were received 175mg/m2 intravenously with same interval. The median treatment cycle was 6.6 cycles(range, 3 to 15 cycles). Patient's response were evaluated with tumor marker(CA-125) and CT or MRI before and after chemotherapy. Responses and toxicities were defined according to the Gynecologic Oncology Group criteria.

Even though malignant potential of vaginal intraepithelial neoplasia(VaIN) may be low, the prevalence is increasing and the mean age at diagnosis is decreasing. Various treatment options have been used for the eradication of ValN, but most effective standard protocol is not present because it is a rare disease. Laser vaporization was used to treat 7 patients with VaIN diagnosed at Department of Obstetrics and Gynecology, Seoul National University Hospital between 1992 to 1996. The patients were from 40 to 70 years of age with a mean 57 of years. All patients had a history of radical or simple hysterectomy, and final pathologic diagnosis were as follows : cervical cancer(n=5), cervical intraepithelial neoplasia(n=l), leiomyoma(n=l). Vaginal intrae-pithelial neoplasia(VaIN) was identified between 4 months and 8 years after first operation. All lesions were unifocal disease and found at the upper one third of the vagina. Treatment was performed with a CO2 laser unit and colposcope. Four(57%) out of seven patients had general anesthesia for the purpose of treatment. Patients were followed up for an average of 16.8 months with regular cytologic evaluation, colposcopy and biopsy. Failure of therapy was defined as evidence of intraepithelial neoplasia in any one of these three parameters. Only one patients showed persistent disease and the others remain free of disease. The success rate of therapy was 85.7%(6/7). (continue)

Interferon(IFN) has been noted to augment the cytotoxicity of cisplatin analogues and S-FU, and varying degrees of success were reported when combined with chemotherapy in a number of squamous cell carcinomas. The aims of this study were to assess its therapeutic efficacy and to establish the feasibility and toxicity of biochemical modulation of the interferon-a-2a when combined with 5-FU and carboplatin(CBDCA) in locally advanced(> or =FIGO clinical stage IJb) and/or bulky(largest diameter > or = 3cm) cervical cancer. From January 1995 to December 1996, 20 patients with bulky and/or locally advanced cervical cancer were enrolled in this study and received FAC(5-FU/Interferon-a/CBDCA) combination chemotherapy as a neoadjuvant setting. The FAC regimen was composed of IFN- a -2a 3x10(6) IU/day from day l to day 6, 5-FU 750mg/m2/day from day 2 to day 6, and carboplatin at a dose calculated by Calvert formula with AUC(area under the curve) 6.0 on day 2. Three cycles of neoadjuvant chemotherapy was performed with 3 weeks interval if toxicity permitted it. Patients were examined after every treatment cycle and evaluated for toxicities and responses using standard GOG criteria. Two patients(10.0%) showed complete clinical response and 15 patients(75,0%) had partial response. The other patients had stable(10.0%) or progressive disease(5.0%). Among fifteen patients who have undergone radical hysterectomy, pathological complete response was not noted. Surgery was possible in 15 patients(75.0%) and 10 patients received adjuvant radiotherapy. Lymph node metastases were found in 5 patients(33.3%) and the number of positive nodes was ranged from 1 to 5. The most frequent grade 3 or 4 toxicity was neutropenia(60.0%) followed by alopecia(40.0%), nausea/vomiting(35.0%), thrombocytopenia(15.0%), diarrhea(5.0%), and anemia(5.0%). (continue)

OBJECTIVE: Large loop excision of transformation zone(LLETZ) is gaining popularity as an alternative to other ablative or cone methods for the treatment of cervical intraepithelial neoplasia(CIN). The optimal management of CIN after LLETZ, however, remains controversial and the reliable predictors of residual disease after LLETZ have not been consistently identified. This study was performed to identify factors to predict residual disease after LLETZ. METHODS: From August 1993 to July 1995, 133 patients who received subsequent hysterectomy after LLETZ in Department of Obstetrics and Gynecology at Seoul National University Hospital were retrospectively reviewed. Residual disease was defined as positive findings of CIN or further advanced findings in hysterectomy specimen. The age of patients, the severity of disease and the status of resection margin(RM) were analyzed for predictive values of residual disease. The Chi-square test, Fisher's exact test and Student t-test were used for statistical analysis. RESULTS: The residual disease after hysterectomy was negative in 85.7%(114/133) and positive in 14.3%(19/133). Among 19 cases with positive residual disease, 3 cases were revealed to be microinvasive cervical cancer. The mean age of patients with no residual disease was 42.5 years(range; 27-71) and that of patients with residual disease was 49.1 years(range; 33-72). Nine out of 94 cases(9.6%) with negative RM and 10 out of 39 cases(25.6%) with positive RM in LLETZ had residual disease. Two out of 14 cases(14.3%) with CIN II and 17 out of 119 cases(14.3%) with CIN III in LLETZ had residual disease. The success of LLETZ which means no residual disease was influenced by the age of patients(p=0.005) and the status of resection margin of LLETZ(p=0.032). CONCLUSION: The negative resection margin in LLETZ does not always guarantee that there is no residual disease. Close preoperative workup and more aggressive treatment plan(wide conization or hysterectomy) should be considered in patients who has higher possibility of positive residual disease such as old age and positive resection margin in LLETZ.

OBJECTIVE: This study was performed to identify the prognostic factor for survival of patients with recurrent cervical cancer. METHODS: Sixty-eight patients were diagnosed as recurrent cervical cancer at the Seoul National University Hospital from January, 1988 to December, 1998. Recurrence was defined as new evidence of tumor after 6 months of disease free survival. Retrospective analysis was done in terms of clinical features and the Cox proportional hazard model was used to identify independent variables associated with an improved survival rate. Histopathologic types were distributed as follows; squamous cell carcinoma in 70.6%, adenocarcinoma in 11.8%, adenosquamous cell carcinoma in 11.8%, and small cell carcinoma in 1.5%. Distribution of FIGO stage was as follows; stage I in 25.0%, stage II in 66.2%, and stage III in 4.4%. Sites of recurrence were as follows; central pelvic recurrence in 44.1%, pelvic side wall recurrence in 11.8%, and distant metastasis in 44.1% and the most common site of distant recurrence was extrapelvic lymph nodes (29.4%). 29.4% of recurrences were observed within the first 12 months after initial therapy, 50.0% within 2 years and 64.7% within 3 years. RESULTS: Positive rate of SCC-Ag at initial diagnosis was 45.2% with cutoff value of 2.0 ng/ml. Positive rate of SCC-Ag at the diagnosis of recurrence was 60.0%. Overall response rate to the treatment was 29.1%. Complete response rate was higher in central pelvic recurrrence than pelvic side wall recurrence and distant metastasis (P = 0.002) and also higher in normal SCC-Ag level (< or = 2.0 ng/ml) at the diagnosis of recurrence than elevated level (P = 0.032). Cumulative survival rates of 1 year after recurrence was 66.8%, 2 year 36.7%, and 5 year 18.7%. Central recurrence showed higher cumulative survival rate than pelvic side wall or distant recurrence (P = 0.029). The patients with elevated SCC-Ag level at the time of diagnosis of recurrence showed lower cumulative survival rate than those with normal SCC-Ag level (P < 0.001). Cox proportional hazard model showed that SCC-Ag elevation at the time of diagnosis of recurrence retained significant values in predicting survival(OR = 2.56; 95% CI = [1.22-5.39]; P = 0.01). CONCLUSION: SCC-Ag elevation at the diagnosis of the recurrence is a strong independent prognostic indicator for survival of patients with recurrent cervical cancer.
