Variation in the facial pattern and effect of the rotational jaw growth on the facial proportion were studied in serial cephalometric radiographs of 40 Korean children (35 boys, 15 girls) ranging in age from 6 to 13 years. According to Y-axis (N-S-Gn) growth change during the 7 years of period, the subject who had exhibited "wave-like" manner of Y-axis growth change within +/- 2degrees was classified to the Parallelwise group and the subject who had exhibited Y-axis increase more than +/- 2degrees was classified to the Clockwise rotation group and the subject who had exhibited Y-axis decrease more than -2degrees was classified to the Counterlockwise rotation group. For the comparison of each group, a total of 22 morphologic variables were employed and the data were analyzed by means of computer morphometrics and statistical methods. On the basis of the finding of this study, the following trends were eatablished: 1. The Parallelwise group was 75%, the Clockwise rotation group was 12.5% and the Counterclockwise rotation group was 12.5%. 2. The growth pattern of cranial base was related to the rotation of mandible. 3. Maxillary prognathism was occured in the Counterclockwise rotation group and the rotation of palatal plane was occured in the Clockwise rotation group. 4. Mandibular prognathism was occured in the Parallelwise and the Counterclockwise rotation groups, especially in the Counterclockwise rotation group. 5. The degree of maxillo-mandibular divergency was constant in the Clockwise rotation group but decreased in the Counterclockwise rotation and the Parallelwise groups, especially in the Counterclockwise group. 6. There were no differences in the size of the anterior upper facial height (N-ANS) and the posterior lower facial height ((Go-Me)-PNS) but there were differences in the size of the anterior lower facial height (ANS-Me) and the posterior upper facial height ((S-N)-PNS) between each group. 7. The growth increment and the size of the facial gepth was not relater to the growth pattern of the face but the growth increment and the size of the facial height was related to the growth pattern of the face. 8. Proportional change due to the facial growth rotation was concentrated in the anterior lower face. 9. The most apparent difference between each group was happened in the size of the posterior cranial base (S-Ba) and the facial length (S-Gn).

There has not been any report on massive air-containing liver abscess in diabetic patients, although emphysematous cholecystitis or pyelonephritis is a well-known complication in them. Authors report two cases of emphysematous liver abscess in diabetic patient, which showed typical findings of massive air-containing hepatic abscess on ultrasonography and computed tomography, but very poor progrosis in spite of immediate and successful percutanoeus drainage procedure.

A 31-year-old woman with surgically proven spinal extradural granulocytic sarcoma was examined with magnetic resonance (MR) imaging. This patient had no evidence of systemic leukemia. The signal intensities of the mass on T1-weighted and gradient echo images were higher than those of spinal cord, which were different from iso-intensity of cases reported by other authors.

A hemagglutination(HA)-typing system has been developed for the presumptive identification of enterotoxigenic Escherichia coli(ETEC) possessing the colonization factor antigens(CFA) Seventy-seven E. coli strains from pediatric patients with or without diarrhea were examined for the mannose-resistant(MR) HA or mannose-sensitive(MS) HA of human, bovine, chicken, and guinea pig erythrocytes and their antibiotic resestances. A significant proportion(68%) of the isolates exhibited the HA pattern of NNNN(experssed in the order human/bovin/chicken/guinea pig erythrocytes), and 10% of the isolates exhibited NNSS, known as the pattern about half of enteropathogenic E. coli serogroups produced. Sixty-nine strains(88%) were resistant to one or more antibiotics; 55(80%) were reristant to four or more antibiotics. The strains showed multiple drug resistance were more higher in HA-positive strains(92% of HA-positive strains) than in HA-negative strains(76% of HA-negative strains) and all of the HA-positive strains with human erythrocytes were resistant to 4 or more antibiotics. There were no significant differences between HA patterns and antibiotic resistance in both the strains from the patients with or without diarrhea. In summary, although the causative organisms in cases of diarrhea of this study have not been established, the date herein suggested that ETEC possessing CFA which produce RRRN or NRRN HA pattern was not participated in this diarrhea.

From 1979 to 2006, fifty eight patients with esophageal atresia were treated by one pediatric surgeon at Hanyang University Hospital. We analyzed the clinical findings and outcome of these 58 patients. There were 30 males and 28 females. Their mean birth weight was 2,960 +/- 400 g (1,170~4,020 g). The most common type of anomaly was Gross type C (49 patients; 84.5 %). There was no type B. Fifty-two patients underwent definitive surgery. Postoperative complications were as follows: anastomotic leakage in 17 patients (32.7 %), anastomotic site stricture in 15 (28.8 %), gastroesophageal reflux in 10 (19.2 %) and recurrent TEF in 1 (1.9 %). A total of 152 associated anomalies were detected from 48 patients (82.2 %). The cardiovascular system was the most commonly affected (30 patients with 46 anomalies). The VACTERL association was present in 14 patients (24.1 %). Operative mortality was 17.3 % including self-discharge patients after operation.

PURPOSE: We performed a retrospective study to compare the accuracy between conventional CT staging and intraoperative staging for advanced gastric cancer. MATERIALS AND METHODS: Sixty patients with advanced gastric cancer were included in this study during the recent 2 year-period. All were pre- and posto- peratively diagnosed as advanced gastric cancer. CTwas performed with G E 9800 and Somatom DR3 under conventional technique in 50 and with others in 10 referred patients. The CT staging for T and N category with emphasis on incurable factor, if not resacted, were performed. And we compared the accuracy between conventional CT and intraoperative staging. The final histo-pathologic staging was used as a gold standard. RESULTS: Accuracy of CT and operation for T4(n=l7) factor is 76.9 % and 86.2 % respectively. Overestimation rate for T4 was 9.3 % by CT and 6.1% by operation, and underestimation rate for was 13.8 % and 7.7 % respectively. Accuracy of CT and operation for N (n=60) factor was 50 % and 60 % respectively. Overestimation rate for N factor was 18.3 % by CT and 18.3 % by operation, and underestimation rate for N factor was 31.7 % and 21.7 % respectively. Correct Tand IM staging was possible only in 33% by CT and 38% by intraoperative assessment. CONCLUSION: Conventional CT and intraoperative staging for incurable T/N factor in advanced gastric cancer have a potential limitations, especially for N factor. Therefore, more reliable modality or technique such as dynamic scanning by spiral CT, transabdominal or endoscopic ultrasonography should be preoperatively performed to complement infrequent errors in intraoperative staging. Furthermore, a histology-oriented surgical approach seems essential in selecting the most appropriate surgical procedure.

Pulmonary Langerhans' cell histiocytosis is an uncommon granulomatous disorder of unknown cause. The authors retrospectively evaluated radiographs and computed tomographic findings of five patients with biopsy-proven pulmonary Langerhans' cell histiocytosis. The main structural abnormalities consisted of small nodules and cystic air spaces, but one case showed only pneumothorax due to bullae rupture. Its distribution has been known predominently in the upper lung fields, but in our cases, the lung lesions were distributed in the entire lung fields or predominently in the lower lung fields. We propose that pulmonary Langerhans' cell histiocytosis is extremely variable of its structural abnormalities and distribution.

OBJECTIVE: The aim of this study was to obtain information on the prognosis and treatment of the low grade endometrial stromal sarcoma. PATIENTS AND METHODS: Three patients with low grade endometrial stromal sarcoma treated in kangnam St. Mary's hospital between 1993 and 2002 were evaluated. The clinical stage, management and outcome were analyzed. RESULTS: Those patients with low grade endometrial stromal sarcoma had a long overall survival in the presence of receiving hormonal therapy after initial surgery. Two are alive with disease-free status, one has shown a partial response to hormonal treatment. CONCLUSION: Surgery is the primary treatment for low grade endometrial stromal sarcoma. High dose hormonal replacement as adjuvant therapy will be associated with a lengthened overall survival in patients with low grade endometrial stromal sarcoma.

PURPOSE: The this study was performed to evaluate whether the extent and location of retroperitoneal hematoma correlate with the severity of renal injury. MATERIALS AND METHODS: We evaluated the CT findings of 27 patients with renal trauma. The retroperitoneal hematoma were subdivided into perirenal hematoma(PRH), anterior pararenal hematoma(APH), posterior pararenal hematoma(PPH) and interfascial hematoma(IFH) The perirenal hematoma (PRH) was classified as grade I, II and III according to the amount of hematoma. RESULTS: PRH was present in all 27, PPH in 8, IFH in 3 patients and APH was not observed. Grade I PRH was present in 7 (70%) of 10 minor injury (contusion, intrarenal hematoma), grade Ill PRH in 2(20%) of 10 minor injury and in 7 (41.2%) of 17 major and catastrophic injury (laceration, fracture, shattered kidney and renal pedicle injury). Eight PPH were present only in the major and catastrophic injury and 3 IFH in each of intrarenal hematoma, laceraton and pedicle injury. CONCLUSION: The location and extent of PRH and PPH correlated somewhat with the severity of renal injury, while the presence of IFH and APH did not correlate with severity of the renal inury.

Leiomyoma is a neoplasm of smooth muscle relatively common in the stomach, but very rare in the duodenal location. Recurrent bouts of severe melana remain the most frequent presenting symptom for leiomyoma. A 69-year-old man presented to us with a 4-day history of melena. Endoscopy revealed norinal mucosa covered ovoid elevated lesion with central linear depression and ulcer at the second portion of duodenum. Endoscopic biopsy showed chronic inflammation only. Duodenal mass was excised through a duodenotomy. Pathological diagnosis was leiomycena.
