Leiomyosarcoma(LMS) is a malignant tumor from smooth muscle origin that arises most commonly in the gastrointestinal tract and uterus, but rarely in the oral and maxillofacial area which lacks smooth muscles. 63 cases of oral LMS have been reported, especially LMS that occurred in the mandibular gingiva is only 2 cases. Major symptom of oral LMS is painful or painless swelling. Besides it, oral LMS has no specific characteristics. So it is difficult to diagnose the case as LMS of the oral cavity. Certain cases report that LMS of the oral cavity was misdiagnosed as periodontitis and the patients were treated with unnecessary procedures. Conventional treatment of LMS is the radical surgical excision. LMS that is infiltrative and very malignant has poor prognosis despite of well-circumscribed boundary. LMS of the oral cavity is often recurred, has high rate of distant metastasis and 5-year-survival rate is as low as 23%. This article reports LMS of the mandibular gingiva that treated with surgical intervention, had local recurrence and metastasis to the lymph node after 16-month's follow-up examination.

Nonparasitic liver cysts are usually asymptomatic and require treatment when they are symptomatic. Hence, many treatment methods, such as percutaneous aspiration, aspiration followed by injection of sclerosing agents into the cyst, excision of the liver cyst, and hepatic resection have been suggested. Recently, the laparoscopic cholecystectomy has become popular, and this method has been challenged as a treatment for symptomatic nonparasitic liver cysts. To evaluate the feasibility of using and the disadvantages of laparoscopic treatment, we reviewed the medical records of 10 patients with a symptomatic nonparasitic liver cyst who were treated by laparoscopic unroofing at the Department of Surgery, Chungbuk National University Hospital. All patients were diagnosed by USG and abdominal CT. All patients had vague abominal discomfort, abdominal distension, or indigestion. The sizes of the liver cysts varied from 7 cm to 20 cm, and half of them were located in the right lobe, the other half in the left lobe. In 5 patients, the cysts were multiple. The mean operative time was 99.5 minutes, and mean hospital stay was 8 days. The follow up period was from 3 to 37 months. Two patients required a reoperation because of cyst infection and a rapidly growing cyst. Remaining cysts were identified in 4 among 8 patients, but they did not have any symptoms. In conclusion, laparoscopic unroofing is feasible as a first choice for treatment of a symptomatic liver cyst. However, in liver cyst that are located at the dome of right side or in a thickened wall, incomplete unroofing and residual cysts can be anticipated. In this case, we suggest that open cyst excision or unroofing may be better than laparoscopic unroofing.

BACKGROUND: Because of the common etiologic factor, such as smoking, lung cancer and chronic obstructive Pulmonary disease are often present in the same patient. The preoperative prediction of remaining pulmonary function after the resectional surgery is very important to prevent serious complication and postoperative respiratory failure. 99mTc-MAA perfusion scan has been used for the prediction of postoperative pulmonary function, but it may be inaccurate in case of large V/Q mismatching. We compared 99mTc-DTPA radioaerosol inhalation scan with 99mTc-MAA perfusion scan in predicting postoperative lung function. METHOD: Preoperative inhalation scan and/or perfusion scan were performed and pulmonary function test were performed preoperatively and 2 month after operation. We predicted the postoperative pulmonary functions using the following equations. Postpneumonectomy FEV1=Preop FEV1x% of total function of lung to remain RESULTS: 1) The inhalation scan showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.94, 0.91, 0.87 respectively). 2) The perfusion scan also showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.86, 0.72, 0.97 respectively). 3) Among three parameters, FEV1 showed the best correlations in the prediction by lung scans. 4) Comparison between inhalation scan and perfusion scan in predicting pulmonary function did not show any significant differneces except FVC. CONCLUSION: The inhalation scan and perfusion scan are very useful in the prediction of postoperative lung function and don't make a difference in the prediction of pulmonary function although the former showed a better correlation in FVC.

Procalcitonin (PCT) is a newly introduced marker of systemic inflammation and bacterial infection. A marked increase in circulating PCT level in critically ill patients has been related with the severity of illness and poor survival. The goal of this study was to compare the prognostic power of PCT and three other parameters, the arterial ketone body ratio (AKBR), the acute physiology, age, chronic health evaluation (APACHE) III score and the multiple organ dysfunction score (MODS), in the differentiation between survivors and nonsurvivors of systemic inflammatory response syndrome (SIRS). The study was performed in 95 patients over 16 years of age who met the criteria of SIRS. PCT and AKBR were assayed in arterial blood samples. The APACHE III score and MODS were recorded after the first 24 hours of surgical ICU (SICU) admission and then daily for two weeks or until either discharge or death. The patients were divided into two groups, survivors (n=71) and nonsurvivors (n=24), in accordance with the ICU outcome. They were also divided into three groups according to the trend of PCT level: declining, increasing or no change. Significant differences between survivors and nonsurvivors were found in APACHE III score and MODS throughout the study period, but in PCT value only up to the 7th day and in AKBR only up to the 3rd day. PCT values of the three groups were not significantly different on the first day between survivors and nonsurvivors. Receiver operating characteristic (ROC) curves for prediction of mortality by PCT, AKBR, APACHE III score and MODS were 0.690, 0.320, 0.915 and 0.913, respectively, on the admission day. In conclusion, PCT could have some use as a mortality predictor in SIRS patients but was less reliable than APACHE III score or MODS.

To validate ventricular diastolic phase parameters of reconstructed transmitral flow rate curve by M-mode, 2-dimensional and pulsed Doppler Echocardiography, these parameters were compared with same parameters by left ventriculography. The study population was 22 patients who received both coronary arteriography and echocardiographic examination. Transmitral flow rate curve and left ventricular filling volume curve were reconstructed from transmitral flow velocity curve by pulsed Doppler, mitral annulus diameter by two diameter by two dimensional and diastolic motion of both mitral leafltes by M-mode echocardiography. From left ventriculography, left ventricular filling volume curve and transmitral flow rate curve were made using area-length method by Sandler and Dodge. From trasmitral flow fraction, 1/2 diastolic time filling fraction, normalized peak filling volume, 1/3 diastolic time filling fraction, 1/2 diastolic time fraction, normalized peak early filling rate and ratio of early to late peak filling rate were measured. Correlation between same parameters derived from echocardiography and left ventriculography were observed. 1) Total diastolic filling volume:correlation coefficient r=0.47, P<0.05. 2) 1/3 diastolic time filling fraction:correlation coefficient r=0.90, P<0.001. 3) 1/2 diastolic time filling fraction:correlation coefficient r=0.80, P<0.001. 4) Normalized peak early filling rate:correlation coefficient r=0.57, P<0.01. 5) Ratio of early to late peak filling rate:correlation coefficient r=0.85, P<0.001. Therefore, left ventricular diastolic phase parameters of reconstructed transmitral flow rate curve using, M-mode, 2-dimensional and pulsed Doppler echocardiography seems to be useful for the noninvasive evaluation of the left ventricular diastolic function.

The purpose of this study is to evaluate the degree of osseointegration of resorbable blasting media (RBM) surface implants retrieved from humans. Three implants in the mandibular molar region that were surface-treated with RBM were retrieved from two patients. The implants were used to manufacture specimens in order to measure the bone-implant contact (BIC) ratio. The BIC ratios of the three implants were found to be an average of 69.0%+/-9.1%. In conclusion, that RBM surface implants are integrated into the host environment with histological significance and the BIC ratio of the RBM surface-treated implant was not significantly different from that of other surface-treated implants.
