The author analyzed detailed pattern of pelvic bone fracture in 52 cases of posterior urethral injuryassociated with pelvic bone fracture in male. The relationship between fracture and urethral injury was reviewed n38 cases who received retrograde urethrography at the time of injury. The pattern of urethral injury due to pelvicbone fracture was newly classified. The results were as follows; 1. In age distribution, the most common was 5thdecade(26.9%). 2. The most freqent type of pelvic rami fracture was two rami fracture(52%). 3. There was no casewith only the superior ramus fracture, and all cases were associated with inferior ramus fracture with or withoutsuperior ramus fracture. 4. In inferior ramus fracture, the ratio of ischial ramus fracture to pubic ramusfracture was 46.1:17.4. 5. In cases with only the ischial ramus or pubic ramus fracture, unilateral fractureexceeded bilateral fracture(44.2:19.3). 6. The bladder rupture was found in 10 among the total 52 cases, 9 ofwhich were associated with superior ramus fracture, and 8 were extraperitoneal type. 7. The most common type ofurethral injury was Type III(73.7%), and followed by Type II(10.5%), Type I(7.9%), and Type IV(7.9%). 8. Theseresults strongly suggested that the superior ramus frature was related to bladder rupture, and inferior ramusfracture to urethral injury.

Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.

The authors performed percutaneous antegrade pyelography guided by ultrasound on 33 patients, from J une 1982 to October 1984, at the department of radiology, Busan National University Hospital. The results obtained were as follows: 1. Of the 31 cases,17 cases (5 1.5%) were female and 16 cases (48.5 %)were male,and age distribution was nearly even, but most prevalent age group was third decade. 2. Comparing intravenous pyelographic findings with ultrasonographic findings, pyelographically non. visualized kidney 15 cases (45 .5%) were hydronephrosis 12 cases, multiple cysts 2 cases, and intrarenal cystic mass 1 case, ultrasonographically. Pyelographically hydronephrosis 9 cases (27.3%) were all hydronephrosis, ultrasonographically. Intrarenal mass 5 cases (15.2%) were all intrarenal cystic mass, NVK with air in kidney 1 case (3.0%) was air in perirenal space, partial NVK 1 case (3.0%) was per. irenal fluid , suprarenal mass 1 case (3 .0%) was suprarenal intrarenal and huge perirenal cystic masses, ultraso nograp h ically. 3. On technical reliability of antegrade pyelography under ultrasound gUide, 31 cases (93 .9%) could be done fluid aspiration and visualization, and 2 cases (6.1 %) could be only done fluid aspiration but failed visualization . 31 successful cases were visualization of collecting systems 23 cases, visualization of cyst 6 cases, i!nd visualization of perirenal space 2 cases. 2 partial successful cases were perirenal injection 1 case and parenchymal injection 1 case. 4. On fluid aspiration, 22 cases (66.7%) were clear, but 11 cases (33.3%) were not clear, which were pus 7 cases, turbid urine 2 cases, bloody urine 1 case, and bloody pus and air 1 case. 5. Comparing ultrasonographic findings with antegrade pyelographic findings, ultrasonographically hydronephrosis 21 cases revealed obstruction in 16 cases, antegrade pyelographically, which were consisted of ureteral stricture 14 cases, ureteral stone 1 case, and ureteral mass 1 case, non-obstruction in 4 cases, which were consisted of pyonephrosis 2 cases, posterior urethral valve 1 case, and megaureter 1 case, and other 1 case was visualization failure. Ultrasonographically intrarenal cystic mass 6 cases were simple renal cyst 4 cases, and infected renal cyst 2 cases, antegrade pyelographically. Multiple cysts 2 cases were lobulated huge renal cyst 1 case, and visualization failure 1 case, which was multi.cystic kidney. Air in perirenal space 1 case was emphysematous pyelone. phritis, suprarenal cystic mass 1 case was complete duplication with ectopic ureteral orifice, perirenal fluid 1 case due to kidney fracture was perirenal fluid , and intrarenal and perirenal cystic mass was per irenal abscess, antegrade pyelographically. 6. On ana lysis of anteg rade pyelography result as next diagnostic step of ultrasound, 31 successful cases were 27 conclusive diagnostic cases (87.1%), and 4 heplful diagnostic cases (12.9%) with percutaneous antegrade pyelography guided by ultrasound . 7. Antegrade pyelography provides significant diagnostic information on the nature of the obstructive lesion and can be performed as an adjunct to retrograde study or as an alterative to a pyelogram. 8. Ultrasonographic examination could be performed easiJy in diagnosis of renal and perirenal diseases as non.invasive method without risk of radiation hazard , and was not influenced by renal function. 9. Ultrasound is considered a most advantageous aid to the performance of antegrade pyelography and has yie lded valuab le diagnostic information in patients with obstructive hydronephrosis.

The reversible cerebral vasoconstriction syndromes (RCVS) is a group of conditions, which is characterized by a reversible segmental constriction, typically associated with recurrent thunderclap headaches, and is often complicated by ischemia or hemorrhagic stroke. Clinical situations, associated with the development of RCVS, include pregnancy or the postpartum period, as well as various medications and illicit drugs. However, vasoconstriction syndromes remain poorly characterized, under-recognized, and difficult to diagnose, because of the lack of specific diagnostic tests or diagnostic criteria. Therefore, we present a first case of reversible cerebral vasoconstriction syndrome of pregnancy complicated with preeclampsia, diagnosed by a magnetic resonance image and angiography, which results in chronic cerebral infarction, with a brief review of the relevant literature.

Phenylketonuria (PKU), an autosomal recessive disorder, occurs in one of 53,000 births in Korea. The disorder is associated with deficient activity of phenylalanine hydroxylase. In PKU, phenylalanine cannot be used in a normal fashion because of the deficient enzyme. Untreated, affected individuals develop marked mental disabilities, behavioral difficulties, seizures, rashes, pigment dilution, and unusual body odor. PKU treatment consists of a phenylalanine-restricted diet supplemented with a phenylalanine-free mixture of amino acids. During the restricted diet, PKU patients have an increased risk of developing vitamin B12 deficiency because of a limited intake of animal products. We report a successful anesthetic management in a patient with phenylketonuria for dental procedures.

A 19-year-old man was referred to Seoul National University Dental Hospital for evaluation of a large painless swelling of the left mandibular angle area in August, 1999. The growth had been first noted 6 years ago. He had visited other hospital in 1997. In spite of the treatment given at the hospital, the mass continued to grow rapidly. Conventional radiographs in 1999 showed an expansile, lobulated, and destructive lesion of the left mandibular body. CT scan demonstrated an expansile mass with a corticated margin. Bony septa were seen within the lesion. Internal calcification noted on the bone-setting CT image, and corresponded to the hypointense area in T1-weighted MRI image. MRI clearly delineated the extent of the lesion which had heterogenous intermediate signal intensity in T1-weighted images and heterogenous hyperintense signal intensity in T2-weighted images. The lesion was well-enhanced. Histopathologically, the lesion was completely encapsulated. Multinucleated giant cells were presented in a fibrous background, demonstrating a storiform pattern. Areas of osteoid rimmed by a few osteoblasts were scattered throughout the lesion. Inflammatory cells, blood vessels, and hemosiderin deposition were also shown. CGCG may show lots of internal calcification foci on the CT, and varied signal intensity in MRI. More cases will be needed to understand the features of the CT and MR finding of CGCG.

OBJECTIVE: To evaluate the relationship between the expression of cytokeratins, Ki-67 and the infection of human papillomavirus 16, 18 type in the carcinogenic progrssion of the uterine cervical epithelium. METHODS: Investigation the expression patterns of CKs and Ki-67 monoclonal antibody, and compared them with the incidence of HPV infection in 120 patients including 30 cases of normal cervical epithelium, 30 cases of LSIL, 30 cases of HSIL and 30 cases of SCC, to possible relationship between them. RESULTS: The expression of CK 14, and Ki-67 increased as the cervical lesions progressed from normal to SILs and SCC. In contrast, CK 13 is decreased as the cervical lesions progressed from normal to SILs and SCC. Statistical analysis revealed significant corelations between the CK 14 and spinal layer, between CK 13 and basal layer, between Ki-67 and all layers. HPV was detected in 16.7% of normal cervical tissue, 50.0% of LSIL, 70.0% of HSIL, 80.0% of SCC with PCR technique. The labelling indices of Ki-67 were significantly higher in HSIL than in normal cervical tissue and LSIL. The labelling indices were also higher in groups with positive reactions to CK 14, 13, and HPV than in groups with negative reactions to them. CONCLUSION: It was postulated that examination of patterns of immunoreactivity of CK 14, 13, and Ki- 67 could be a useful and convenient tool to explain the trasition from normal cervical epithelium to SCC via LSIL and HSIL and thereby predict the differentiation potential of the studies for lesions.

BACKGROUND: The delta neutrophil index (DNI) is a useful marker for diagnosing and predicting the prognosis of sepsis. The purpose of this study was to investigate the usefulness of DNI as a prognostic marker in patients within the pediatric intensive care unit (PICU), as well as its association with other prognostic factors. METHODS: A total of 516 children admitted to Severance Children's Hospital PICU from December 2009 to February 2015 were analyzed. DNI was measured on the day of PICU admission. Mortality was defined as death within 28 days following PICU admission. RESULTS: The median value of DNI was 1.2% (interquartile range [IQR] 0-4.3%) in the survivor group and 9.5% (IQR 2.3-20.8%) in the non-survivor group, and the difference was statistically significant (p < 0.001). DNI was significantly positively correlated with ICU scores such as Pediatric Index of Mortality 3 and Pediatric Risk of Mortality III, as well as with C-reactive protein and lactate levels. The area under the receiver operating characteristic curve of DNI for mortality was 0.748 (95% CI: 0.687-0.808) and the cut-off value was 4.95%. CONCLUSIONS: The initial DNI level can be considered a useful indicator for predicting prognosis in PICU patients.

BACKGROUND: Serum albumin as an indicator of the disease severity and mortality is suggested in adult patients, but its role in pediatric patients has not been established. The objectives of this study are to investigate the albumin level as a biomarker of poor prognosis and to compare it with other mortality predictive indices in children in intensive care unit (ICU). METHODS: Medical records of 431 children admitted to the ICU at Severance Hospital from January 1, 2012 to December 31, 2015 were retrospectively analyzed. Children who expired within 24 hours after ICU admission, children with hepatic or renal failure, and those who received albumin replacement before ICU admission were excluded. RESULTS: The children with hypoalbuminemia had higher 28-day mortality rate (24.60% vs. 9.28%, P < 0.001), Pediatric Index of Mortality (PIM) 3 score (9.23 vs. 8.36, P < 0.001), Pediatric Risk of Mortality (PRISM) III score (7.0 vs. 5.0, P < 0.001), incidence of septic shock (12% vs. 3%, P < 0.001), C-reactive protein (33.0 mg/L vs. 5.8 mg/L, P < 0.001), delta neutrophil index (2.0% vs. 0.6%, P < 0.001), lactate level (1.6 mmol/L vs. 1.2 mmol/L, P < 0.001) and lower platelet level (206,000/µl vs. 341,000/µl, P < 0.001) compared to the children with normal albumin level. PIM 3 (r = 0.219, P < 0.001) and PRISM III (r = 0.375, P < 0.001) were negatively correlated with serum albumin level, respectively. CONCLUSIONS: Our results highlight that hypoalbuminemia can be a biomarker of poor prognosis including mortality in the children in ICU.

PURPOSE: This study evaluated color stability of Dentca 3D-printed denture teeth, in comparison to color stabilities of four conventional types of denture teeth, upon being immersed in various colorants.MATERIALS AND METHODS: Four types of conventional prefabricated denture teeth (Surpass, GC, Artic 6, Heraeus Kulzer, Premium 6, Heraeus Kulzer, Preference, Candulor), 3D-printed denture teeth (Dentca); and Z250 (Filtek Z250, 3M ESPE) were prepared for testing. The samples were immersed in erythrosine 3%, coffee, cola, and distilled water (DW) at 37℃. Color change (ΔE) was measured by spectrophotometer before immersion and at 7, 14, and 21 days after immersion. One-way analysis of variance was performed along with Tukey's honestly significant difference multiple comparisons test (P<.05).RESULTS: No great difference was observed between the color change of Dentca denture teeth and that of conventional denture teeth in most cases (P>.05). The color change of Dentca denture teeth immersed in erythrosine 3% was greater than that of Surpass (ΔE = 0.67 ± 0.25) after 1 week; Artic 6 (ΔE = 1.44 ± 0.38) and Premium 6 (ΔE = 1.69 ± 0.35) after 2 weeks; and Surpass (ΔE = 1.79 ± 0.49), Artic 6 (ΔE = 2.07 ± 0.21), Premium 6 (ΔE = 2.03 ± 0.75), and Preference (ΔE = 2.01 ± 0.75) after 3 weeks (P<.05).CONCLUSION: A color change was observed in Dentca denture teeth when immersed in some colorants; however, the maximum value of ΔE for Dentca denture teeth was within the clinically acceptable range.
