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.

Uterine sarcomas are relatively rare tumors of mesodermal origin that constitute 2-6% of uterine malignancies. Uterine sarcomas include endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), malignant mixed m llerian tumor (MMMT) of both homologous and heterologous type, pure heterologous sarcomas, blood vessel sarcomas, and lymphoma. Endometrial stromal tumors are divided into three types: 1) endometrial stromal nodule, 2) low-grade stromal sarcoma or endolymphatic stromal myosis, and 3) endometrial stromal sarcoma. The low grade endometrial stromal sarcoma is very rare. It shows occasional local recurrence, which might arise from endometrial stroma, from adenomyosis, and rarely from endometriosis. We have experienced a case of low grade endometrial stromal sarcoma of the uterus in a 54-year-old woman, which is presented with a review of literatures.

Purpose: To report a case of contact lens-related infectious keratitis caused by three different bacterial species.Case summary: A 40-year-old man presented with pain and redness in his left eye. His best-corrected visual acuity (BCVA) in the affected eye was 20/25. Slit-lamp examination revealed a 3 × 3 mm corneal epithelial defect with infiltration located 1 mm inferior to the pupil. Following admission, a microbial culture test was performed, and empirical antibiotic therapy was initiated. On the fourth day, Pseudomonas aeruginosa was isolated from the corneal sample and the contact lens, while Serratia marcescens and Stenotrophomonas maltophilia were isolated from the contact lens case. Based on the results of the antibiotic susceptibility tests, 0.5% moxifloxacin, fortified amikacin, and ceftazidime were administered topically and intravenously. The corneal epithelial defect reduced to 1 × 1 mm by the eleventh day of admission. After two months, BCVA improved to 20/20 with no remaining corneal epithelial defect, although an inactive corneal opacity persisted at the previous ulcer site. Conclusions Contact lens wear can be associated with polymicrobial keratitis involving three distinct Gram-negative bacteria, which may present greater treatment challenges compared to monomicrobial keratitis. Microbial culture testing of the contact lens, its case, and corneal scrapings is essential for identifying the causative organisms and selecting appropriate antibiotic therapy.

PURPOSE: Deep vein thrombosis and pulmonary embolism are common and potentially fatal complication among hospitalized patients. The first clinical manifestation of venous thromboembolism may be fatal pulmonary embolism. Therefore, some form of prophylaxis is warranted for patients at risk. Prolonged major surgery is well known as high risk factor in development of venous thromboembolism and venous thromboembolism following surgery remains a significant health care problem. But little data are available concerning the changes of venous hemodynamic during prolonged surgery. METHOD: To access the relationship of the lower leg venous congestion that occurred during prolonged and position-fixed surgery to the development of postoperative deep vein thrombosis, the venous pressure of lower leg were measured continuously. A flexible indwelling angiocatheter was inserted into the greater saphenous vein near ankle area and venous pressure was measured by pressure monitor. The data of patients (experimental group:n=10) who performed spinal operation in Jack-Knife position over 180 minutes, healthy volunteers (n=10) and patients (venous hypertension group) who diagnosed as lower leg deep vein thrombosis (n=7), chronic venous insufficiency (n=3) were collected and analyzed. RESULT: The mean age was 34 years old in experimental group and the patients were 7 males and 3 females. The mean lower leg venous pressures of healthy volunteer in Jack-Knife position were 42.89+/-3.52 mmHg at 30 minutes. In acute deep vein thrombosis and chronic venous insufficiency patients, the mean venous pressures were 73.14+/-4.78, 57.33+/-2.52 mmHg at 30 minutes and these data were statistically significant compared with control group (P<0.05). In experimental group, the changes of the mean venous pressures at 30, 60, 90, 120 and 180 minutes were 48.78+/-2.38, 45.89+/-2.09, 45.33+/-2.24, 45.11+/-2.03 and 46.33+/-2.18 mmHg and these data were not statistically significant compared with control group. There was no postoperative development of deep vein thrombosis. CONCLUSION: The surgical factors (prolonged operation time, fixed position) and anesthetic factor may not play a major role in development of postoperative deep vein thrombosis and other postoperative factors will intervene the development of deep vein thrombosis.

OBJECTIVE: To investigate the expression of fragile histidine triad (FHIT) protein and the possible relationship between FHIT expression and clinicopathological indices in cervical adenocarcinoma. METHODS: FHIT protein expression was examined in 40 cases of cervical adenocarcinoma stage Ia to IIa and 28 cases of corresponding normal endocervical tissue by immunohistochemical method. We analyzed the relationship between the reduction of FHIT protein expression and several prognostic factors such as histological grade, lymph node metastasis, tumor size, cervical invasion depth and parametrial invasion. We used Fisher's exact test for statistical analysis. RESULTS: The FHIT protein expression was positive in 77.5% (31/40) of cervical adenocarcinoma tissue, and reduced its expression in 22.5% (9/40) whereas positive in 100% (28/28) cases of adjacent normal endocervical gland. The FHIT expression was decreased in 14.3% (4/28) of cancers without lymph node metastasis but 55.5% (5/9) of those with metastasis (p=0.023). And the reduction of FHIT expression was found in 34.8% (8/23) of grade II and III cancers and only 6.3% (1/16) of grade I (p=0.056). CONCLUSION: Loss of FHIT protein expression may be associated with metastasis and poor prognosis of cervical adenocarcinoma.

BACKGROUND: Recent restriction enclonuclease analysis studies hsve revealed that MCV DNA can be classified into two major types, designated MCV-1 and MCV-2, by th:ir restriction enzyme cleavsge patterns. In earlier reports of MCV DNA analysis, MCV-2 was the main virus type found in genital lesions. However many recent studies cienied the relationship between virus type and anatomical distribution. OBJECTIVE: The purpose of this study was to examine the ratio of MCV-l to MCV-2 in Korean isolates of MCV DNA and the relationship between MCV subtypes and with clinical features such as anatomical location, age, sex, numiber of lesions, and atopic dermatitis. METHODS: MCV DNA extrated from 112 cases of Korean patients waa examined by restriction endonuclease analysis using Brtm HI. RESULTS: 1. MCV-1 was found in 108 of 112 (96.4%) patients and MCV-2 in of 112 (3.6%) patients. The ratio of MCV-1 to MCV-2 wss 28:1. 2. There was no significant ciprrelation between MCV subtypes and the age, sex, number of lesions, atopic dermatitis, and anatoimic loction. 3. Lesions induced by MCV-1 MCV-2 were indistinguishable on the brsis of size and form. CONCLUSION: This study showis that the ratio of MCV-1 to MCV-2 was 28:1 in Korean molluscum contagiosum patients and there was no relationship between MCV subtyies and lesional morphology or snatomical distribution.
