Fibrolipoma is a rare histological variant of lipoma characterized by proliferation of mature fat and fibrous tissue. Most of the benign lipomatous tumors in the palm reported in the literature developed in the nervous tissue, especially the median nerve sheath. We report an unusual form of fibrolipoma on the palm which arose from the subcutaneous tissue or superficial palmar fascia in the palm, not the nerve or tendon sheath. There was no recurrence 3 years after surgical removal was performed.

BACKGROUND: The maximum surgical blood order schedule (MSBOS) is a viable option for reducing unnecessary crossmatching and achieving significant cost savings in the blood bank. In this study, we showed the process establishing MSBOS and through a prospective study, we evaluated the efficacy of MSBOS. METHODS: We organized task force team for transfusion management improvement composed of a director of the blood bank, surgeons and anesthesiologists in the Committee for Quality Improvement (CQI) of Asan Medical Center. In this team, we established MSBOS for most elective surgeries through the review of the previous transfusion and crossmatching data. We introduced MSBOS in April 1998 and prospectively analyzed surgeon's acceptance rate of MSBOS, crossmatch-to-transfusion ratio (C/T ratio), blood wastage rate, and cost savings. RESULTS: During the first 19 months after introducing MSBOS at our hospital, there was gradual increase in the surgeon's compliance rate of MSBOS from 30% to 94.0% through continuous education. The C/T ratio was changed from 3.5 to 1.6 and blood wastage rate was decreased from 4.0% to 1.9%. And also we could save more than 38,400,000 won through not performing the unnecessary crossmatches of 7,680 cases per year. CONCLUSION: Introduction of MSBOS can have a significant impact in reducing C/T ratio, blood wastage rate, and unnecessary crossmatches for the unused blood units. For successful application of MSBOS, cooperation with surgeons and anesthesiologists and continuous education is essential.

PURPOSE: This study was designed to evaluate diagnostic accuracy of serial electrocardiograms(ECG), myocardial band of creatinine phosphokinase(CK)(CK-MB/CK ratio) and two dimensional echocardiography(ECHO) for myocardial injury in patients with blunt chest trauma. METHODS: We prospectively investigated 54 patients(male : 38, female : 16, mean age : 41) with severe blunt chest trauma. Presence of myocardial injury was determined by increase(>0.1ug/L) of peak serum troponin T(TnT) concentration from serial mesurements. RESULTS: Among 54 patients with blunt chest trauma, 23 patients(43%) had increased peak TnT level which suggested of myocardial injury. Among 23 patients with increased TnT, abnormal ECG findings were found in 18(78%) and echocardiographic abnormalities were observed in 17(74%). Cardiovascular events in 9(39%) of 23 patients with increase Tnt. There was no cardiovascular events in patients with normal TnT. CONCLUSION: Significant proprotion of patients with blunt chest trauma had elevated TnT value which suggested of myocardial injury. We recommend echocardiagraphy and serial tracing of ECG to verify the clinical significance of elevated TnT in patients with blunt chest trauma.

One hundred and two patients with benign prostatic hyperplasia were treated by transurethral radio-frequency thermotherapy (TURT) device (Thermex-II, Direx, Israel) with 47.5 degrees C in single session for 2 hours and 30 minutes from November 1992 to October 1993. Among them, 83 patients, who were followed up for more than 3 months were included in this study. Twenty-seven (32.5%) patients had a history of acute retention. Pretreated values of the mean Madsen-Iversen symptom score, maximum urine flow rate, postvoiding residual urine volume, prostate volume and prostate specific antigen (PSA) were 15.4, 6.5 ml/sec, 61.3ml, 43.2ml and 0.77 ng/ml respectively. Madsen-Iversen symptom score, maximum urine flow rate were measured at 2 weeks, 1, 3 and 6 months after TURT. The residual urine volume, prostate volume and PSA level were measured at 3 and 6 months after TURT. During the follow up, the symptom score started to decrease significantly at 1 month (9.9, p< 0.01) after TURT, and gradually decreased up to 6.9 at 3 months. The maximum flow rate showed initial significant improvement at 2 weeks (8.1 ml/sec., p< 0.01), but no significant interval change was observed thereafter. The residual volume decreased significantly at 3 months (41.3 ml, p< 0.01) and no decrement was noted until 6 months. Neither the prostate volume nor PSA value changed significantly at 3 or 6 months after TURT. The improvement, which was defined as a change of 50% or more in at least one of subjective or objective symptoms showed in 63.9% (53/83) at 3 months and 57.1% (32/56) at 6 months. Both subjective and objective improvements at 3 and 6 months after treatment showed in 24.1% and 19.6%, respectively.

Teratoma is one of germ cell tumor, common neoplasm in women of reproductive age, but it can arise at any age. Its malignant transformation is rare, less than 2%, frequently at older age. Nearly all the cases are squamous, sarcomatous and adenomatous transformation. Here we present a case of mixed transformation, adeno-squamous cell carcinoma with brief review of the concerned literature.

It is often difficult, on the basis of clinical examination and conventional investigations, to evaluate the functional impairment of brain in children with cerebral palsy in which early detection remains a challenge. This study was designed to know the usefulness of single photon emission tomography(SPECT) of the brain with technetium-99 m hexamethylpropyleneamineoxime (99mTc-HMPAO) as a semiquantitative method of determination of right-left asymmetries in tracer uptake and a change in antero-posterior regional cerebral blood flow(rCBF) distribution. We investigated 33 children with cerebral palsy aged from 4 months to 48 months(mean 19.3 months). The results were as follows: right to left ratio and regional index of a transverse view were useful to quantify the decrease of tracer uptake in left hemiplegia, but not in right hemiplegia who were all mild in severity, and in tetra- and diplegia in which cerebral lesions were found bilaterally; cortico-cerebellar ratios of a sagittal view were found useful to detect a decrease of rCBF distribution in tetra- and diplegia ,which was not distinct by means of right to left ratio and regional index on transverse view. The results suggest that semiquantitative analysis of 99mTc-HMPAO Brain SPECT would be a valuable complementary tool for determination of topographical involvement in cerebral palsy.

BACKGROUND: Epithelial-mesenchymal transition (EMT) is critical for morphogenesis during embryonic development and is also implicated in the conversion of early-stage tumors into invasive malignancies. Recently, Twist has been identified to play an important role in EMTmediated metastatic progression of several types of human cancer. The present study examined the expression of Twist and evaluated its clinicopathologic significance in urothelial carcinoma of upper urinary tract. METHODS: Immunohistochemical staining for Twist expression was performed on 70 upper urinary tract urothelial carcinomas (UUT-UCs) using tissue microarray. RESULTS: Immunohistochemical staining for Twist was positive in 31/70 cases (44.3%) of UUT-UCs. Twist expression was associated with high-grade and advanced-stage (ISUP grade, p<0.01; stage, p=0.045). The patients with Twist positive-tumors revealed lower disease free survival rate than those with Twist negative-tumors (p<0.01). The overall survival for patients with Twist positive-tumors was slightly worse than the patients with Twist negative- tumors, but the difference was not statistically significant (p=0.12). CONCLUSION: Our results suggest that Twist is a novel marker for advanced UUT-UC.
