One of the most frequent structural chromosomal anomaly is t(8;21)(q22;q22) that occurs in approximately 5-15% of all acute myeloid leukemia (AML). However, t(3;21)(p21;q22) and t(2;11)(q31;p15) translocations are rarely reported in AML. Here, we report a unique case of AML with two translocations, t(3;21;8)(p21;q22;q22) and t(2;11)(q31;p15). Using multiplex reverse transcription polymerase chain reaction, we identified a RUNX1-RUNX1T1 fusion gene. Following a second relapse, the patient did not respond to therapy and died 55 months following the first diagnosis. We believe that this is the first case describing concurrent chromosomal aberrations involving three-way t(3;21;8) and two-way t(2;11) translocations in de novo acute myeloid leukemia.

PURPOSE: In order to avoid functional disability that may be caused by radical excision or amputation in extremity soft tissue sarcomas, authors employed limb-conserving surgery together with extemal radiation therapy plus interstitial brachytherapy. MATERIALS AND METHODS: From June 1995 to Febrary 1997, 10 extremity soft tissue sarcoma patients were treated with limb-conserving surgery and external radiation therapy plus interstitial brachytherapy. In six patients, whose histologic diagnoses were made at the time of surgery, wide or marginal excision and interstitial brachytherapy was done 4 weeks before postoperative external radiation therapy. In four patients whose histologic confinnations were done before definitive treatment, preoperative external radiation therapy was given 4 weeks before surgery and interstitial brachytherapy. The types of surgery were wide excision in five patients, and marginal excision in five patients. Gross or microscopic residual was left at the surgical resection margins in four patients. The brachytherapy dose ranged from 17.5 Gy to 24 Gy and external beam radiation did from 40 Gy to 45 Gy. RESULTS: With the median follow-up duration of 21.5 months(range: 13 to 29 months); one local recurrence, and three new distant metastases were observed. There were three patients with wound complications attributable to the current treatment regimen. CONCLUSION: Satisfactory local tumor control may be achievable with limb-conserving surgery and external radiation therapy plus brachytherapy in patients with extremity soft tissue sarcomas, while more caution should be used to avoid wound problems.

BACKGROUND: Diabetic nephropathy is the most frequent complication in patients with diabetes mellitus (DM). In clinical practice, the glomerular filtration rate (GFR) is often estimated from serum creatinine. Recently, serum cystatin C has been suggested being a better parameter for diagnosis of impaired renal function. We evaluated serum cystatin C as a potential new marker of GFR in diabetes patients. METHODS: Serum cystatin C and serum creatinine (sCr) were measured in 73 DM patients to evaluate their usefulness in diabetic patients. DM patients were divided into three groups (whole DM patients, albuminuric patients, and DM patients with sCr<1 mg/dL). Serum cystatin C and sCr were compared with creatinine clearance (CCr). RESULTS: The overall correlation coefficient for the reciprocal of serum cystatin C was superior to that of the reciprocal of serum creatinine in all three patient groups. With CCr cut-off values of 60 mL/min and 80 mL/min, receiver operating characteristic (ROC) plotting demonstrated that serum cystatin C had a higher sensitivity and specificity for detecting decreased GFR than did serum creatinine in all three patient groups. CONCLUSIONS: These findings suggest that serum cystatin C is superior to serum creatinine as a marker of GFR measured by correction or mean ROC-plot AUC in diabetic patients; therefore, serum cystatin C could be used for the early detection of the impairment of renal function.

This was a clinical trial study to aid the recovery of elderly female alcoholic liver disease patients by providing a balanced nutritional supplement comprising soymilk. All patients gave their consent before enrolling. The average demographics of the subjects were age 81.57 years, height 150.43 cm, weight 52.67 kg, and body mass index 24.15 kg/m2 . An increase in the daily consumption of fruits and fruit juice was observed after the patients had started taking the balanced meal as compared to before. Intakes of vitamin A, vitamin C, vitamin E, and cholesterol decreased after consuming soymilk, whereas vitamin B 12, niacin, folic acid, and dietary fiber significantly increased (P<0.05). Blood cholesterol and BUN levels showed a decreasing tendency.Our results indicate that consuming soymilk in a balanced diet for female patients afflicted with alcoholic liver disease helps improve their nutritional status by increasing the nutrients lacking in the body.

PURPOSE: In this study, we retrospectively analyzed the clinical outcomes of patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) grafted from HLA-matched parents. METHODS: Seven children with acute leukemia (4 acute lymphoblastic leukemia, 3 acute myeloid leukemia) in first complete remission received allogeneic HSCT from their respective parents at the St. Marys Hospital between April, 1999 and October, 2005. The median age of patients at transplantation was 5 years (range, 1-11 years; 2 male, 5 female) and the median age of donors was 35 years (range, 30-41 years; 5 male, 2 female). We investigated the clinical outcomes such as engraftment, acute and chronic graft-versus-host disease (GVHD), transplant-related morbidity and mortality, relapse and survival. RESULTS: Median time from transplantation to last follow-up was 69.5 months (range, 18.8-96.5 months). All patients were successfully engrafted, with a median time of 11 days (range, 10-16 days) and 26 days (range, 13-39 days) for neutrophil and platelet recovery, respectively. Grade II acute GVHD occurred in 3, and grade III acute GVHD in 1 of 7 recipients. Extensive chronic GVHD developed in 2, and limited chronic GVHD in 1 of 7 recipients. Death from transplant-related complications occurred in 1, and relapse occurred in 1 of 7 recipients. Estimated 5-year overall survival was 83+/-15%. CONCLUSION: The clinical outcomes of recipients who underwent HSCT from HLA-matched parents were comparable to those of patients who received HSCT grafted from HLA-matched sibling donors in childhood leukemia. HLA typing of parents, as well as siblings will increase the likelihood of finding an HLA-matched family donor for patients who need HSCT.

PURPOSE: This study is to evaluate the efficacy of small bowel displacement system (SBDS) in post-operative pelvic radiation therapy (RT) of rectal cancer patients by measurement of small bowel volume included in the radiation fields receiving therapeutic dose. MATERIALS AND METHOD: Ten consecutive new rectal cancer patients referred to the department of Radiation Oncology of Samsung Medical Center in May of 1997 were included in this study. All patients were asked to drink Gastrographin before simulation and were laid prone for conventional simulation and CT scans with and without SBDS. The volume of opacified small bowel on CT scans, which was to be included in the radiation fields receiving therapeutic dose, was measured using picture archiving and communication system (PACS). RESULTS: The average small bowel volumes with and without SBDS were 176.0ml (5.2- 415.6ml) and 185.1ml (54.5- 434.2ml), respectively. The changes of small bowel volume with SBDS compared to those without SBDS were more than 10% decrease in three, less than 10% decreaseintwo,lessthan10%increaseinthree,andmorethan10%increaseintwopatients. CONCLUSION: No significant advantage of using SBDS in post-operative pelvic RT for rectal cancer patients has been shown by small bowel volume measurement using CT scan considering additional effort and time needed for simulation and treatment setup.

BACKGROUND: Acinetobacter baumannii infections are difficult to treat owing to the emergence of various antibiotic resistant isolates. Because treatment options are limited for multidrug-resistant (MDR) A. baumannii infection, the discovery of new therapies, including combination therapy, is required. We evaluated the synergistic activity of colistin, doripenem, and tigecycline combinations against extensively drug-resistant (XDR) A. baumannii and MDR A. baumannii. METHODS: Time-kill assays were performed for 41 XDR and 28 MDR clinical isolates of A. baumannii by using colistin, doripenem, and tigecycline combinations. Concentrations representative of clinically achievable levels (colistin 2 microg/mL, doripenem 8 microg/mL) and achievable tissue levels (tigecycline 2 microg/mL) for each antibiotic were used in this study. RESULTS: The colistin-doripenem combination displayed the highest rate of synergy (53.6%) and bactericidal activity (75.4%) in 69 clinical isolates of A. baumannii. Among them, thedoripenem-tigecycline combination showed the lowest rate of synergy (14.5%) and bacteri-cidal activity (24.6%). The doripenem-tigecycline combination showed a higher antagonistic interaction (5.8%) compared with the colistin-tigecycline (1.4%) combination. No antagonism was observed for the colistin-doripenem combination. CONCLUSIONS: The colistin-doripenem combination is supported in vitro by the high rate of synergy and bactericidal activity and lack of antagonistic reaction in XDR and MDR A. baumannii. It seems to be necessary to perform synergy tests to determine the appropri-ate combination therapy considering the antagonistic reaction found in several isolates against the doripenem-tigecycline and colistin-tigecycline combinations. These findings should be further examined in clinical studies.

BACKGROUND AND OBJECTIVES: Survivors of pediatric hematopoietic stem cell transplantation (HSCT) are at risk for developing hypertension. The objectives of this study are to evaluate the prevalence and risk factors of early onset hypertension during the engraftment period after HSCT. SUBJECTS AND METHODS: This is a retrospective study of 157 consecutive patients (mean age at HSCT: 9.1+/-5.1 years) who underwent HSCT for acute myeloid leukemia (n=47), acute lymphoblastic leukemia (n=43), severe aplastic anemia (n=41), and other reasons (n=26). Blood pressure data were collected at five time points: 0, 7, 14, 21, and 28 days after HSCT. Hypertension was defined as having systolic and/or diastolic blood pressure > or =95th percentile according to age, gender, and height. To analyze the risk factors related to hypertension, data, including patients' demographic and transplant characteristics, were reviewed. RESULTS: Hypertension developed in 59 patients (38%), among whom 12 (7.6%) required long term therapy. Thirty-two (54%) patients had systolic and diastolic, 8 (14%) had only systolic, and 19 (32%) had only diastolic hypertension. Younger age, acute graft-versus-host disease, sinusoidal obstruction syndrome, treatment with antifungal agent, and greater increase in serum creatinine (Cr) levels were associated with hypertension. Multivariate analysis showed that younger age at HSCT and greater increase in serum Cr level were independent risk factors for hypertension. CONCLUSION: Prevalence of hypertension during immediate post-HSCT period is high, especially in younger children. A greater increase in Cr after HSCT was significantly associated with hypertension. Further study is needed to elucidate long-term cardiovascular complications in pediatric HSCT survivors.

Fulminant myocarditis is characterized by critical illness at presentation. However, if affected patients recover with pharmacologic therapy and mechanical circulatory support, they may have a better long-term prognosis than patients with other forms of myocarditis. A 31-year-old man was admitted due to chest pain associated with dyspnea. Electrocardiogram showed ST-segment elevation in all leads except for aVR and aVL. Non-sustained ventricular tachycardia developed 12 hours after admission. The echocardiography showed diffuse hypokinesia, concentric edematous thickening of the left ventricular wall, and pericardial effusion. Serum cardiac enzymes and absolute eosinophil count were elevated. Since the ELISA (Enzyme-Linked Immunosorbent Assay) against Paragonimus westermani was positive, the patient was treated with praziquantel for 2 days. Eosinophil count normalized after 10 days, with conversion to negativity on ELISA after 4 weeks. We concluded that his myocarditis was probably caused by allergic reaction secondary to Paragonimus westermani infection.

Iatrogenic aortic dissection occurs in association with diverse invasive procedures. It occurs primarily as a complication of cardiac surgery or after catheterization procedure. We found a case of iatrogenic abdominal aortic dissection caused by traumatic needle injury. The patient complained of abdominal pain after balloon kyphoplasty. Abdominal computed tomography (CT) showed intramural hematoma with air density suggestive of an iatrogenic cause. The patient was managed conservatively, and no lesion progression was noted in the follow-up CT. To the best of our knowledge, this is the first case of iatrogenic aortic dissection associated with kyphoplasty.
