The Rastelli operation has been a standard procedure for repairing complete transposition of the great arteries combined with a ventricular septal defect and pulmonary stenosis. Yet this procedure has several shortcomings, including the risk of incurring left ventricular outflow tract obstruction on long-term follow-up. In this regard, aortic translocation has recently been regarded as a potent alternative to Rastelli's operation. We report here on a case of complete transposition of the great arteries that was combined with an inlet-extended perimembranous ventricular septal defect and pulmonary stenosis in a 2-year-old boy. All the problems were successfully repaired using the aortic translocation technique. Postoperative echocardiography showed a straight and wide left ventricular outflow tract.

Frictional force between the orthodontic bracket and arch wire during sliding tooth movement is related to many factors, such as the size, shape and material of both the bracket and wire, ligation method and the angle formed between the bracket and wire. There have been clear conclusions drawn in regard to most of these factors, but as to the effect of bracket width on frictional force there are only conflicting studies. This study was designed to investigate the effect of bracket width on the amount of frictional forces generated during clinically simulated tooth movement. Three different widths of brackets (0.018x0.025"standard), narrow (2.40mm), medium (3.00mm) and wide (4.25mm) were used in tandem with 0.016x0.022" stainless steel wire. Three bracket-arch wire combinations were drawn on for 4 minutes on a testing apparatus with a head speed of 0.5mm/min and tested 7 times each. To reproduce biological conditions, dentoalveolar models were designed with indirect technique using a material with similar elastic properties as periodontal ligament (PDL). In addition, to minimize the effect of ligation force, elastomer was used with added resin, which was attached to the bracket to make up for the discrepancies of bracket width. The results were as follows: 1. Maximum frictional force for each bracket-arch wire combination was: Narrow (2.40mm) : 68.09+/-4.69 gmf Medium (3.00mm) : 72.75+/-4.98 gmf Wide (4.25mm) : 72.59+/-4.54 gmf 2. Frictional force was increased with more displacement of wire through the bracket slot. 3. The ANOVA post-hoc test showed that the bracket width had no significant effect on frictional force when tested under clinically simulated conditions (P>0.05)

Subcellular localizaton of HBcAg have been found to be related to the activity of liver disease and HBV replication. The aim of this study was to determine whether the degree of expression of HBcAg in the hepatocyte nucleus and cytoplasm reflects the level of viral replication and histological activity in chronic HBV infection. A total of 102 patients with biopsy proven chronic hepatitis B were included. There was a highly significant correlation between the levels of HBV DNA in serum and the degree of expression of HBcAg in the nucleus for HBeAg-positive(p=0.000) and negative patients(p=0.04). There was a highly significant, correlation between the degrees of expression of HBcAg in hepatocyte cytoplasm and histologic activities (p<0.01) for HBeAg-positive patients. The degrees of expression of HBcAg in the hepatocyte cytoplasm correlated positively with the lobular activities (p<0.01), but not correlated with the portal activity and fibrosis for HBeAg-negative patients. In conclusion, in the young patients with chronic B viral hepatitis, the degree of expression of HBcAg in the hepatocyte nucleus may affect viral load, and the degree of expression of HBcAg in the hepatocyte cytoplasm may affect histologic activities of liver disease.

Adenomyoepithelioma (AME) of the breast is an uncommon tumor characterized by its dual differentiation into luminal cells and myoepithelial cells. In most cases these tumors have a benign clinical course, but distant metastases have been reported. We present the case of a 51-year-old woman diagnosed with malignant AME. The patient underwent a right modified radical mastectomy, and pathological examination confirmed the diagnosis of malignant AME. Ten months after the operation, multiple hepatic, pleural, and abdominal wall metastases were detected. A number of palliative chemotherapeutic agents were tried, including anthracycline and taxanes. However, the disease continued to progress, and superior vena cava syndrome developed as a result of direct tumor invasion. The patient received salvage eribulin monotherapy. After two cycles of this treatment, her clinical symptoms were ameliorated, and a computed tomography scan showed a partial response. Eribulin chemotherapy was thus effective in treating malignant AME in this case.

Uterine artery embolization for the treatment of uterine leiomyomas is gaining acceptance as an effective alternative to surgical treatment in preserving uterus and reducing symptoms. Vaginal expulsion of leiomyomas after UAE is uncommon, and has been regarded as a side effect of the procedure, as well as a natural phenomenon of treatment response. A-28-year-old unmarried woman who has been suffered from menorrhagia underwent UAE. MRI revealed the remnant leiomyomas were reduced in size and volume and also symptoms of leiomyomas were much improved. After 6 month, We've made sure about non-visualization of leiomyoma on follow-up pelvic dynamic MRI. We report this rare case of vaginal expusion of intramural leoimyoma with a brief literature.

PURPOSE: High voltage electrical injury mainly occurs in the industrial field. It can cause serious complications and sequelae that lead to high social and economic costs. We investigated the causes of this to try to help prevent these injuries. METHODS: We reviewed 128 patients who incurred high voltage electrical injury during a 3-years period from Jan. 1, 2006 to Dec. 31, 2008. We performed a retrospective analysis of the medical records to review the epidemiology. We also performed a survey by telephone. The survey questions addressed the following: the duration of work, wearing safety equipment, the reason for working without safety equipment, did they receive safety education, was the safety education adequate, recognition of a high tension wire before working and did they understand the effect of high voltage on the human body. RESULTS: The safety education was relatively carried out well. But most patients did not wear safety equipment even though they knew they had to wear it (92%). The major reason was discomfort of wear it (72%). The hand was the most common injury site (80%). Most injuries occurred with 22,900 volt or less (92%). In spite of safety education, many patients were unaware of the effects of electrical injury on their body. CONCLUSION: Strengthened safety education can play a significant role in preventing high voltage electrical injury. At this point, the doctors who are experienced in treating high voltage electrical injury must actively participate in this safety education. We suggest that handy safety equipment can lessen the incidence of high voltage electrical injury. It is essential to develop a handy safety glove for 22,900V with considering that the hand was the most common injury site and the most frequent voltage for injury was 22,900 volt or less.

BACKGROUND: It was reported that patients who have left ventricular hypertrophy have higher D allele frequency of angiotensin I-converting enzyme gene polymorphism, especially in Caucasian normotensive men. We studied to know whether genetic polymorphism of angiotensin I-converting enzyme gene is associated with the development of left ventricular hypertrophy in Korean people whose genotype frequency is quite different from that of Caucasians. METHODS: Total 156 patients were included in this study. Presence of hypertension was checked with the criteria that hypertensives are one whose blood pressures were all above 140/90 at least 3 times spanning 2 months or one who had been diagnosed as hypertension and on his medication. Left ventricular mass index(LVMI) was calculated using electrocardiogram by Rautaharju equation, and left ventricular hypertrophy(LVH) was defined as LVMI was above 131g/m2 in male or above 110g/m2 in female. Genomic DNA was extracted from the mononuclear cell of each subjects and PCR was performed using new primers for the region of intron 16 and exon 17. RESULTS: Genotype frequencies of D/D genotype and D allele were 0.200 and 0.413 respectively in group with LVH(n=40), 0.103 and 0.392 respectively in group without LVH(n=116). There was no significant difference with each other group. However, when only the normotensives were included in this analysis, frequency of D/D genotype is significantly higher in group with LVH(0.231, n=26) than in group without LVH(0.076, n=79)(Fisher's exact test,p<0.05). There was no significant difference in genotype frequency between the normotensives(n=105) and the hypertensives(n=51). CONCLUSIONS: In Korean people, D allele of polymorphism of angiotensin I-converting enzyme gene is also associated with development of left ventricular hypertrophy in the normotensives and is not associated with essential hypertension.

Several studies have shown associations between irinotecan toxicity and UGT1A genetic variations in colorectal and lung cancer, but only limited data are available for gastric cancer patients. We evaluated the frequencies of UGT1A polymorphisms and their relationship with clinicopathologic parameters in 382 Korean gastric cancer patients. Polymorphisms of UGT1A1*6, UGT1A1*27, UGT1A1*28, UGT1A1*60, UGT1A7*2, UGT1A7*3, and UGT1A9*22 were genotyped by direct sequencing. In 98 patients treated with irinotecan-containing regimens, toxicity and response were compared according to the genotype. The UGT1A1*6 and UGT1A9*22 genotypes showed a higher prevalence in Korean gastric cancer patients, while the prevalence of the UG1A1*28 polymorphism was lower than in normal Koreans, as has been found in other studies of Asian populations. The incidence of severe diarrhea after irinotecan-containing treatment was more common in patients with the UGT1A1*6, UGT1A7*3, and UGT1A9*22 polymorphisms than in controls. The presence of the UGT1A1*6 allele also showed a significant association with grade III–IV neutropenia. Upon haplotype and diplotype analyses, almost every patient bearing the UGT1A1*6 or UGT1A7*3 variant also had the UGT1A9*22 polymorphism, and all severe manifestations of UGT1A polymorphism-associated toxicity were related to the UGT1A9*22 polymorphism. By genotyping UGT1A9*22 polymorphisms, we could identify high-risk gastric cancer patients receiving irinotecan-containing chemotherapy, who would experience severe toxicity. When treating high-risk patients with the UGT1A9*22 polymorphism, clinicians should closely monitor them for signs of severe toxicity such as intense diarrhea or neutropenia.

Hyperthermia can cause severe complications such as rhabdomyolysis, which can induce acute kidney injury. Normal thermoregulation can be disturbed by high fever, and maintenance of a normal body temperature by external cooling can reduce oxygen consumption, and increase vascular tone. Several studies have been conducted to determine the effectiveness of external cooling in treat rhabdomyolysis or renal failure. We report a case of rhabdomyolysis leading to multiple organ dysfunction, including renal failure. The use of an external cooling device achieved fever control and successfully treated rhabdomyolysis and renal failure.
