A retrospective study was made of 10 consecutive patients who underwent mandibular reconstruction with PCBM from December 1994 to July 1996. Free autogenous iliac bone in the from of particulate cancellous bone and marrow was densely packed into the crib that was adapted to bridge the mandibular discontinuity defect. Frozen-treated autogenous mandibular bone, splitted autogenous rib, and titanium mesh(Dumbach, Leibinger) were used as cribs carrying the PCBM. All ten cases underwent successful healing with the formation of a continuous bony union with the remaining mandible. The rate of resorption was assessed by sequential panoramic radiographs. The mean horizontal dimension of the madibular defects was 44mm and the mean vertical dimension of the reconstructed segments was 23mm. The bony height of the reconstructed segments retained about 90% of the bony height of over a 1-year period. We confirmed that PCBM grafts were the most successful and predictable grafts in mandibular discontinuity reconstruction.

A fetal rhabdomyomatous nephroblastoma is considered to be a predominantly monophasic mesenchymal variant of Wilms' tumor, which acts less aggressively than a conventional Wilms' tumor despite its much larger size. Bilaterality of this tumor in a nine month-old girl, however, may negatively affect the overall prognosis. A radical nephrectomy for bulky masses in the left kidney and a partial nephrectomy for right kidney with five small tumor masses was performed at the same time. Two small tumor masses in the upper part of right kidney were left behind because of preserving minimal renal functional capacity. Pathological study revealed a mixed type of nephroblastoma which was composed predominantly of mesenchymal components with fetal rhabdomyomatous differentiation. After post-operative chemotherapy with vincristine, actinomycin D and adriamycin, and radiotherapy(2,130 rad), residual tumor masses became a single tumor 5 cm in diameter and well demarcated, which was resected at 15 months after first operation when the size and renal function of remained right kidney was appropriate to resect out the residual tumor. The tumor resected out at second operation was entirely composed of scattered differentiated fetal skeletal muscle cells in the fibrovascular tissue. Only a few entrapped epithelial components were seen but no blastemal cornponents were present. Follow up abdominal CT and ultrasonographic examinations revealed no evidence of tumor recurrence. The girl has developed normally without disease.

Carcinosarcoma of the female genital tract, also called malignant mixed mullerian tumor (MMMT), is a rare and relatively aggressive tumor with various homologous and heterologous components. There have been various studies to find prognostic factors and to investigate the histogenesis, including tissue culture, electron microscopy, and immunohistochemical studies. We investigated carcinomatous, sarcomatous, and transitional areas of 6 cases of carcinosarcoma of the uterus and ovary by using epithelial and mesenchymal markers. Immunohistochemical profiles of the transitional areas were significantly different from those of carcinomatous and sarcomatous areas. Immunoreactivities for cytokeratin and epithelial membrane antigen (50% and 22.2%) were weaker than those of carcinomatous areas (95.2% and 100%), but stronger than those of sarcomatous areas (11.1% and 5.6%)(p<0.01). In transitional areas, vimentin, smooth muscle actin and S-100 protein were more strongly expressed than in carcinomatous areas, but more weakly expressed than in sarcomatous areas (p<0.01, p<0.01, and p=0.018, respectively). Myoglobin was entirely negative in carcinomatous areas and immunoreactive in minor portions of transitional and sarcomatous areas (22.2% and 16.7%, respectively). These results suggest that the transitional areas are between the carcinomatous and sarcomatous nature in differentiation, further supporting that the carcinosarcomas of the female genital tract may arise, through metaplastic change, from a type of carcinoma.

Nineteen patients suffering from post-traumatic intracerebral hematoma, being managed by stereotactic aspiration of hematoma were evaluated. The outcome in this series is quite satisfactory, with 58% of patients having a functional survival. Eight patients died, of which three patients died of brain swelling and 5 died of systemic causes such as respiratory failure, gastrointestinal(GI) bleeding, and renal failure. It is our belief that stereotactic aspiration is helpful in managing patients with traumatic intracerebral hematoma without herniation and wevere brain swelling.

BACKGROUND: Hypothermia is a condition that can lead to serious complications and even to death in newborn. Although the temperature control is essential in neonatal care, it is often neglected during urgent transfer from local private hospitals. The purpose of this study is to evaluate the incidence and clinical outcomes of transfer induced neonatal hypothermia. SUBJECTS AND METHOD: In this retrospective study, subject is limited to transferred outborn babies with age less than 24 hours from June 1996 to May 1999. A total of 3,086 patients were admitted in NICU during the study period and inborn and outborn babies were 1,743(56%) and 1,343(44%) respectively. Among the 1,343 outborn babies, 212 babies were transferred from the private hospital within 24 hours of birth and were eligible for the study. Rectal temperature on arrival, transfer time, birth weight, gestational age, initial arterial gas study, and clinical outcome were compared. Statistical analysis has been done with chi-sqaure test and multiple logistic regression analysis. RESULTS: There were 84 cases(39.6%) hypothermia(<36degrees C> among the 212 babies and the rate of hypothermia in transfered babies have not decreased over the study period. There were significantly more hypothermia in lower gestational age (less than 28 weeks) and lower birth weight (less than 2,000gm) caused hypothermia significantly more than normal gestational age or normal range of birth weight. And time interval (less than 12 hour) from birth to arrival at emergency department was also significant factor in hypothermia. The mortality rate was three fold higher in hypothermia than normothermic or hyperthermic babies. CONCLUSION: This study shows that hypothermia during neonate transportation is a major cause of neonatal mortality and morbidity in prehopital care. Body temperature control during transport of neonates under 24 hours of age should be emphasized for the better outcome of treatment.

Three patients with primary non-Hodgkin's lymphoma of the uterine cervix are reported and the literature is reviewed. All the three patients in the current study presented with vaginal bleeding. They were found to have diffuse large cleaved cell lymphoma, one of which was multilobated variant with marked sclerosis. Histologically, differential diagnsis from undifferentiated small cell carcinoma, endometrial stromal sarcoma & other sarcomas was difficult and requires special stains including immunobistochemical study. Vaginal pap smears were diagnosed as 'class V; malignant lymphoma' in only one patient. Immunologically, two cases were beta-cell lineage and one case was T-cell lineage. All the patients were treated with chemotherapy only and showed good responses.

OBJECTIVE: This study investigated whether it is possible to use a two-dimensional (2D) standard in three-dimensional (3D) analysis, by comparing the angles and lengths measured from a midsagittal projection in 3D cone-beam computed tomography (CBCT) with those measured by 2D lateral cephalometric radiography (LCR). METHODS: Fifty patients who underwent both LCR and CBCT were selected as subjects. CBCT was reoriented in 3 different methods and the measuring-points were projected onto the midsagittal plane. Twelve angle values and 8 length values were measured on both LCR and CBCT and compared. RESULTS: Repeated measures analysis of the variance revealed statistically significant differences in 7 angular and 5 linear measurements among LCR and 3 types of CBCT (p < 0.05). Of these 12 measurements, multiple comparisons showed that 6 measurements (ANB, AB to FH, IMPA, FMA, Co-Gn, Go-Me) were not significantly different in pairwise comparisons. LCR was significantly different from 3 types of CBCT in 3 angular (SN to FH, interincisal angle, FMIA) and 2 linear (S-Go, Co-ANS) measurements. The CBCT method was similar for all measurements, except for 1 linear measurement, i.e., S-N. However, the disparity between the mean values for all parameters was within the range of clinical measurement error. CONCLUSIONS: 3D-CBCT analysis, using midsagittal projection, is a useful method in which the 2D-LCR normative values can be used. Although the measurements changed with reorientation, these changes were not clinically significant.
