An asymptomatic 26-year-old man was initially admitted with a suspicious mediastinal mass. On the basis of the contrast-enhanced chest CT findings, aneurysm formation involving the left cervical aortic arch associated with subaortic left innominate vein was diagnosed. The aneurysm was confirmed by MR angiography and DSA. The arch aneurysm was surgically removed. We describe this case, and review the literature.

Nodular type malignant melanoma is uncommon in fingers. In previous publications, treatment, diagnosis and case reports of subungal melanoma is often, however fingertip lesion was not focused. A 64-year-old woman who had a non-healing red and dark colored nodular mass with ulceration over the finger tip in the right thumb visited our clinics. Biopsy results was malignant melanoma then we performed amputation surgery of distal phalanx. Lymph node biopsy and resection margin was negative for melanoma. Chemotherapy was administered immediately. After 5 months, pulmonary nodular lesion was found and diagnosed as metastatic malignant melanoma by the wedge resection surgery. The patient is treated for additional chemotherapy consistently and disease free for 2 years. Nodular type melanoma of the finger is uncommon and it could be presented as ulceration and amelanotic nodular mass. Therefore we recommend biopsy to diagnose correctly if there are chronic non healing lesions on the fingers.

BACKGROUND: Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. METHODS: A total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland) plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA) in 61 patients. Their mean age was 35.2 years (range, 15-84 years). Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla. RESULTS: Complications occurred in eight (3.4%) of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction. CONCLUSIONS: Inadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations.

Acute renal failure can be the result of acute renal cortical necrosis (RCN), which commonly occurs from complications occurring during pregnancy. RCN is rarely caused by medications, although tranexamic acid, which is used in patients with acute bleeding for its antifibrinolytic effects, reportedly causes acute RCN in rare cases. An 82-year-old woman experienced gastrointestinal bleeding after endoscopic papillectomy of an ampullary adenoma. The bleeding was controlled with tranexamic acid administration; however, 4 days later, her urine volume decreased and she developed pulmonary edema and dyspnea. Serum creatinine levels increased from 0.8 to 3.9 mg/dL and dialysis was performed. Abdominal pelvic computed tomography with contrast enhancement revealed bilateral RCN with no renal cortex enhancement. Renal dysfunction and oliguria persisted and hemodialysis was continued. Clinicians must be aware that acute RCN can occur after tranexamic acid administration to control bleeding.

OBJECTIVES: The purpose of this study was to evaluate the characteristics of psychopathology, adverse drug effects, and subjective response to drugs that have a significant impact on the subjective quality of life in schizophrenic patients receiving atypical antipsychotics. METHODS: One hundred and one schizophrenic patients, who were receiving maintenance treatment with atypical antipsychotics, were evaluated. Subjective quality of life was assessed using the standardized Korean modification of a self-rating scale to measure subjective well-being under neuroleptics (KmSWN). Patients' psychopathology was evaluated using the Positive and Negative Syndrome Scale. Adverse effects and subjective response to drug were evaluated using the Liverpool University Neuroleptic Side Effect Rating Scale and the Drug Attitude Inventory-10, respectively. Correlation analysis and stepwise multiple regression analysis were conducted. RESULTS: In psychopathology, the severity of depression and anxiety showed the most significant correlation with the score of KmSWN. In adverse drug effects, the severity of psychic side effect and extrapyramidal side effect showed the most significant correlation with the score of KmSWN. Regarding subjective response to drug, significant correlation was observed between the severity of subjective negative response and the score of KmSWN. Stepwise multiple regression analysis revealed that psychic side effect, extrapyramidal side effect, and depression contributed significantly to the total score of KmSWN. These variables accounted for 59.7% of the total variance. CONCLUSION: The results of the present study suggest that psychic side effect, extrapyramidal side effect and depressive symptom are the clinical characteristics that are significantly associated with the subjective quality of life. An effective management strategy for these variables should be established in developing a treatment program to enhance the quality of life of patients with schizophrenia.

Thrombospondin-1 (TSP-1) level is tightly regulated at the transcriptional level. To determine the detailed molecular mechanisms of TSP-1 expression, nine serial 5'-deletion constructs of the human genomic tsp-1 promoter (nucleotides -2,220 to +756) were prepared, inserted into luciferase reporter plasmids, and transiently transfected into the Hep3B human hepatocarcinoma cell. Among the nine 5'-deletion constructs, pTSP-Luc-4 (-767~+756) had consistently decreased luciferase activity with or without PMA stimulation, whereas a further truncated construct [pTSP-Luc-4' (-407~+756)] had increased levels of expression. By searching the nucleotides from -767 to -407, a consensus binding sequence (5'-CCATTTT-3') for the repressor Yin Yang-1 (YY-1) at nucleotide -440 was identified. The suppression induced by this site was weakened in the presence of the region upstream of nucleotide -767 (pTSP-Luc-1 and -2). Nuclear protein directly bound to an oligonucleotide containing the repressive YY-1 sequence but the binding capacity of the sequence was decreased by the increased c-Jun levels. Moreover, proteins immunoprecipitated with anti-YY-1 revealed an interaction between c-Jun and YY-1 factor. These data suggest that the repressive YY-1 site of the tsp-1 promoter could not be functional via activating positive cis-elements on the upstream from this site and weakened via c-Jun/YY-1 interactions.

PURPOSE: The purpose of this study was to identify the effects of a multi agent obesity control program in obese school children. This program was composed of strategies to modify diet and exercise habits and to change cognitive behavior variables(stress, coping, and self-efficacy). METHOD: The subjects were 40 obese school children who participated in our project voluntarily via homepage, TV, newspaper, public paper and school official documents. The program was implemented daily for 4 sessions per day for ten days from August 16 to 26, 2004. The daily program consisted of exercise therapy, dance therapy, cognitive behavior therapy and aroma therapy. The data was analyzed by paired t-test using the SPSSWIN program. RESULT: There was a significant decrease in children's waist-hip ratio (p=.04) and in children's stress (p=.00) after the program. There was a significant increase in children's self-confidence after the program(p=.02) and a significant decrease in children's diet habit after the program(p=.02). CONCLUSION: This study provides evidence that a multiagent obese control program is effective in changing waist-hip ratio, stress, self-confidence, and diet habits in obese school children.

Natural infections with influenza A viruses have been reported in a variety of animal species including humans, pigs, horses, sea mammals, and birds. Although viruses of relatively few haemagglutinin(HA) and neuraminidase(NA) subtype combinations have been isolated from mammalian species, all subtypes, in most combinations, have been isolated from birds. During the past few years, several subtypes of avian influenza A have been shown to cross the species barrier and infect humans. During an outbreak of a highly pathogenic influenza A(H5N1) virus among poultry in Hong Kong in 1997, 6 of 18 people with confirmed infection died. And a total of 89 human infections with influenza A(H7N7), including 1 resulting in the death of a Dutch veterinarian, occurred during the extensive outbreak in 2003. During late 2003 and early 2004, there were reports of large outbreaks of H5N1 among poultry throughout Asia (including Korea, Japan, Indonesia, Vietnam, Thailand, Laos, Cambodia, and China). In Korea, we had also highly pathogenic avian influenza(HPAI) outbreak in 2003~2004 with a first suspected case reported on 10 December 2003. The case was reported at a parent stock farm for broilers, which was located in Chungbuk province, and the farm was immediately placed under movement restrictions. Laboratory tests confirmed the outbreak of HPAI on 12 December 2003. Up to 20 March 2004, a total of 19 farms were confirmed as having been infected with HPAI virus. No further outbreaks occurred after that date. Fortunately there were no human cases founded in this epidemic in Korea. In January 2004, there was confirmation that influenza A(H5N1) virus had been isolated from patients who had died of a respiratory illness in Vietnam. Total 107 human confirmed cases were reported until June 2005 to WHO, threatening new pandemic outbreak. We reviewed our prevention and control strategies of avian influenza and preparedness to the pandemic outbreak.

Human toxocariasis is a common helminthozoonosis due to the infestation of toxocara canis or toxocara cati larvae, and is a common cause of blood eosinophilia in Korea. Toxocariasis has various clinical manifestations depending on the involved organ, and cardiac involvement can range from asymptomatic to fulminant myocarditis with cardiogenic shock. Treatment of toxocariasis is based on corticosteroid and anthelmintic therapies. Here, we report a case of a 57-year-old male with eosinophilic myocarditis caused by toxocariasis as diagnosed via serial echocardiography follow up.
