The pubic bone is an unusual site for an aneurysmal bone cyst. This case, a 15year old male patient, was diagnosed as an aneurysmal bone cyst in the superior ramus of the right pubic bone. He was treated by complete excision of the superior ramus and on five years follow up no problems were noted in terms of weight bearing as well as hip function or evidence of recurrence.

Much has been learned of the pathogenesis and pathophysiology of the toxic shock syndrome (TSS) since the initial description in 1978 by Dr. James K, Todd. The clinical illness is defined by the criteria listed in the case definition formulated for epidemiologic studies. With the advent of widespread recognition of TSS, there have been numerous published reports describing the clinical and laboratory findings, primarily in menstruating females. And there have been also reported about six cases in Korea. Moreover, TSS is uncommon in the prepubertal age group and no case report in infant in Korea. We experienced two cases of TSS in infants aged 11/2 yrs and 9 months associated with respiratory infection-pneumonia, pyopneumothorax and localized skin abscess that were confused with Kawasaki disease (KD). The diagnosis was made on the basis of clinical features and laboratory findings, and the cases met the Centers of Disease Control case definition of TSS. And thus we report these cases and review related literatures.

4.Biological and Genetic Characteristics of Clinically Isolated Enterobacter cloacae with Multidrug Resistance.
Laboratory Medicine Online 2018;8(3):99-106
BACKGROUND: From January 2014 to December 2015, 69 clones of Enterobacter cloacae showing multidrug resistance to six classes of antimicrobial agents were collected from two medical centers in Korea. METHODS: Minimum inhibitory concentrations were determined using the E-test method, and 17 genes were detected using polymerase chain reaction (PCR). The epidemiological relatedness of the strains was identified using repetitive element sequence-based PCR and multilocus sequence typing. RESULTS: The 69 E. cloacae clones produced extended spectrum β lactamase (ESBL) and AmpC and showed multidrug resistance to cefotaxime, ceftazidime, and aztreonam. We identified the following sequence types: ST56 of type VI for ESBL SHV (N=12, 17.4%); ST53, ST114, ST113, and ST550 of types I, IV, VI, and VII, respectively, for CTX-M (N=11, 15.9%); and ST668 of type III for the carbapenemase NDM gene (N=1, 1.5%). The AmpC DHA gene (N=2, 2.89%) was confirmed as ST134, although its type was not identified, whereas EBC (MIR/ACT; N=18, 26.1%) was identified as ST53, ST24, ST41, ST114, ST442, ST446, ST484, and ST550 of types V, I, III, IV, VII, and VI, respectively. The formed subclasses were bla CTX-M-3 and bla CTX-M-22 by CTX-M-1, bla CTX-M-9 and bla CTX-M-125 by CTX-M-9, bla DHA-1 by DHA, and bla MIR-7 and bla ACT-15,17,18,25,27,28 by EBC (MIR/ACT). CONCLUSIONS: There were no epidemiological relationships between the gene products and the occurrence of resistance among the strains.

PURPOSE: This study aimed to compare cerebral hemispheric volumes between pharmacologic treatment and supportive management of patent ductus arteriosus (PDA). METHODS: The study was conducted retrospectively. The subjects of period 1 group were very low birth weight infants whose PDA were treated with pharmacologic closure. Period 2 group were treated with supportive management. Regional brain volumes measured using magnetic resonance imaging were compared between the two groups. RESULTS: total of 12 infants were included. Their median gestational age was 27⁺⁶ (range: 24⁺¹–31⁺¹) weeks and birth weight was 1,065 g (range: 690–1,380). Between the two groups, there was no difference in Apgar score, incidence of bronchopulmonary dysplasia, necrotizing enterocolitis, and culture proven sepsis. The regional brain volumes such as gray matter (Period 1 group, 76,833 mm³ [55,759–100,388] vs. Period 2 group, 79,870 mm³ [59,957–113,018], P=0.59), white matter (82,993 mm³ [63,130–121,311] vs. 92,576 mm³ [77,200–104,506], P=0.18), cerebrospinal fluid (17,167 mm³ [9,279–22,760] vs. 14,348 mm³ [7,018–27,604], P=0.94), basal ganglia (2,065 mm³ [1,697–2,482] vs. 2,306 mm³ [2,065–3,009], P=0.18), and cerebellum (18,374 mm³ [14,843–24,657] vs. 18,096 mm³ [16,134–23,627], P=0.94) were not different between the two groups. CONCLUSION: Regional brain volumes were not different between pharmacological and conservative treatment in infants with PDA. Further wellcontrolled studies are required to evaluate the advantages or disadvantages of supportive management without pharmacologic treatment of PDA.

PURPOSE: Surgical excision has been the primary treatment for hepatoblastoma and hepat-ocellular carcinoma. However, at presentation, only one third of such tumors are surgically resectable. Without operation, the disease is fatal. Therefore, neoadjuvant chemotherapy has been introduced for conversion of the unresectable tumors into the resectable ones. We studied th e effects of chemotherapy for hepatic malignancy in children. METHODS: Between November 1986 and August 1993, 30 children presented with hepatoblastomas or heptocellular carcinoma, which were diagnosed by histology. We analysed the laboratory findings of hepatic tumors and the outcome of chemotherapy. RESULTS: Laboratory findings revealed mild anemia, elevated SGOT/SGPT, and extremely increased AFP level. Twenty-six among 30 patients entered into surgery or neoadjuvant chemotherapy. Initial complete resection of tumor was attempted in 11 case, and was successful in 9 cases. Fifteen cases with initially unresectable tumors were treated with chemotherapy including cisplatin and/or doxorubicin. Nine of 15 showed significant reduction in tumor size, and delayed resection of the primary lesion was possible. But one case did not respond to chemotherapy, and 5 cases was droped out due to death(n=2) and refusal of chemotherapy(n=3). Twenty p atients were enrolled in survival analysis. Over-all 3 year survival rate was 61%, and 2 year survival rates of hepatoblastoma and hepatocellular carcinoma were 85% and 33% respectively(P=0.06). According to the stage, 2 year survival rate of stage I and III were 87% and 75% respectively. None of patient with metastasis survived at 16 months. Chemotherapy was tolerable in most patients and its principal toxicities were myelosuppression and fever. Three patients developed decreased left ventricular shortening fraction and their cumulative dose of doxorubicin were 771mg/m2, 557mg/ m2, and 390mg/ m2. CONCLUSIONS: Chemotherapy including cisplatin and/or doxorubicin is an effective treatment in inducing surgical resectability in hepatoblastomas which are unresectable at diagnosis.

Transformation and progression of breast cancer are thought to be caused by an accumulation of complex genetic alterations, but little is known about specific changes. In this study, the author has undertaken a genome-wide screening to detect genetic changes in 20 cases of breast cancer among Koreans, including 16 infiltrating ductal carcinomas, 2 medullary carcinomas, 1 invasive lobular carcinoma, and 1 borderline phyllodes tumor. Comparative genomic hybridization (CGH) was used to screen for DNA sequence gains and losses across all human chromosomes. Simultaneous immunohistochemical staining for c-erbB-2 (Her-2/neu), c-myc, cyclin D1, and p53 protein was done to make comparisons with nuclear grade and that with CGH results. Biotin-labeled tumor DNA and digoxigenin-labeled normal DNA were hybridized to normal metaphase cells. The fluorescence signals were captured by fluorescence microscope after detection by avidin-FITC and anti-digoxigenin rhodamine. Then, the ratio of fluorescence was calculated by an image analyzer. The immunohistochemical staining was done in paraffin-embedded tissue with an LSAB kit and avidin-biotin complex (ABC) method. The CGH results showed gains on chromosomes 8q (40%), 1q (30%), 17q (15%), 20q (15%), 18q (15%), 5p (15%), and 13q (15%). Deletions were on chromosomes 17p (45%) and 22q (20%). High-level amplifications (green/red ratio >1.5) were noted on chromosomes 1p31, 1q, 3q25-qter, 5p, 7q31-qter, 8q, 9p22-qter, 10p, 11p, 11q22-qter, 12p, 12q24, 14q21-qter, 15q23-qter, 17q, 18p, 18q12-qter, 20p, and 20q. By comparison with infiltrating ductal carcinoma, the two medullary carcinomas showed high-level amplification on chromosomes 1p31, 1q, 8q, 10p, 11p and 12p. c-erbB-2, c-myc, cyclin D1, and p53 protein expression was immunohistochemically detected in 9 of 20 (45%), 8 of 20 (40%), 10 of 20 (50%), and 13 of 20 (65%), respectively. The results indicate that the amplification on chromosome 8q, 1q and the deletions on chromosomes 17p and 22q are the most frequent genetic alterations in breast cancers among Koreans. The results reveal a different pattern of genetic alteration from previous studies. The CGH results were not correlated with the immunohistochemical profiles. The amplification pattern of medullary carcinomas was quite different from the pattern of infiltrating ductal carcinomas. The CGH was thought to be very useful in the screening of genetic alterations of solid tumors.

Because available therapy cannot always distinguish between malignant and nonmalignant cells, the toxicity ofchemotherapeutic agents to normal tissue remains a troublesome issue. Various chemotherapeutic agents such asbleomycin, doxorubicin, cyclophosphamide and L-asparaginase, which cause pulmonary fibrosis, cardiomyopathy,pancreatitis, and hemorrhagic cystitis, respectively, are familiar to radiologists. The purpose of this report isto describe the radiologic findings of various organ abnormalities related to chemotherapy.

OBJECTIVE: The purpose of this study was to correlate permeability parameters measured with dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) using a clinical 3-tesla scanner with extravasation of Evans blue in a rat model with transient cerebral ischemia. MATERIALS AND METHODS: Sprague-Dawley rats (n = 13) with transient middle cerebral artery occlusion were imaged using a 3-tesla MRI with an 8-channel wrist coil. DCE-MRI was performed 12 hours, 18 hours, and 36 hours after reperfusion. Permeability parameters (K(trans), v(e), and v(p)) from DCE-MRI were calculated. Evans blue was injected after DCE-MRI and extravasation of Evans blue was correlated as a reference with the integrity of the blood-brain barrier. Correlation analysis was performed between permeability parameters and the extravasation of Evans blue. RESULTS: All permeability parameters (K(trans), v(e), and v(p)) showed a linear correlation with extravasation of Evans blue. Among them, K(trans) showed highest values of both the correlation coefficient and the coefficient of determination (0.687 and 0.473 respectively, p < 0.001). CONCLUSION: Permeability parameters obtained by DCE-MRI at 3-T are well-correlated with Evans blue extravasation, and K(trans) shows the strongest correlation among the tested parameters.
