Angiomyxolipoma is a rare variant of lipoma, which is described by Mai, 1996, at first. The nine cases of which have been reported to date. Microscopically, the lesion consists of adipose tissue with the paucicellular myxoid areas and fat tissue with numerous thin, dilated, and congestive blood vessels. The reported cases mostly located to the superficial layer on the scalp, subungual, extremities in adults. We report one case of angiomyxolipoma located in the submuscular and parosteal area in the distal femur around knee joint in a child.

PURPOSE: This study compared the results between PFN (Proximal Femoral Nail) and DHS (Dynamic Hip Screw)in the treatment of a peritrochanteric fracture of the proximal femur. MATERIALS AND METHODS: 33 patients with peritrochanteric fractures treated with PFN for a minimum follow-up of at least 12 months were analyzed retrospectively. The patients with PFN group (n=33, group I) were taken from operations between Jan. 2003 and Dec. 2004, and the DHS group (n=34, group II) were used as the control group. Both groups were compared with regard to the operation time, blood loss, transfusion, ICU care, drain amount, duration of admission, complications, the neck shaft angle, the sliding length of lag screws, radiological union, and the functional recovery grade using Jensen and Palmar and Parker's method. RESULTS: The mean operative times were 105 (group I) and 157 minutes (group II), blood losses were 540 and 840cc, transfusion volumes were 1.5 and 2.2 pints, ICU care was 6 and 30%, drain amounts were 36 and 203 cc, admission duration was 25 and 33 days, complications were 15 and 17%, reoperations by the failure of the reduction were 2 cases(6%) (group I) and 0 (group II), difference in the neck shaft angles were 3.70 and 3.87degrees, sliding length of the lag screws were 1.9 and 6.9 mm, radiological union was achieved in 17.5 and 18.9 weeks, function scores were 1.81 and 1.94, and the mobility scores were 6.51 and 6.16, respectively. These results show that there were advantages of PFN in terms of the operative times, blood loss, transfusion, ICU care, drain amounts, admission duration, sliding length of the lag screws and radiological union with statistical significance (p<0.05). CONCLUSION: Good clinical results can be achieved with PFN compared with the DHS for the treatment of peritrochanteric fractures of the proximal femur.

Inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, known as statins, are widely used for primary and secondary prevention of coronary artery atherosclerosis. Pathogenesis of atherosclerosis is multistep processes where transendothelial migration of various leukocytes including monocytes is a crucial step. Interferon-gamma(IFN-gamma) contributes in this process by activating macrophages and T-lymphocytes, and by inducing adhesion molecules in vascular endothelial and smooth muscle cells. In this study we investigated the expression of intercellular cell adhesion molecule- 1 (ICAM-1) in transformed endothelial cell line ECV304 cells as influenced by lovastatin, tumor necrosis factor-alpha (TNF-alpha) and IFN-gamma. Results show that lovastatin suppresses expression of ICAM-1 by inhibiting the IFN-gamma-induced extracellular signal-regulated kinase (ERK) p44/p42-STAT1 signaling pathway. In cells treated with lovastatin and IFN-gamma.ICAM-1 was expressed at a lower level than in cells treated with IFN-gamma alone. However, lovastatin does not reduce TNF-alpha induced expression of ICAM-1. A similar result was observed in cells treated with the MEKK inhibitor PD98059 and IFN-gamma. Cis-acting DNA sequence elements were identified in the 5'-flanking region of the ICAM-1 promoter that mediate inhibition by lovastatin; these sequences map to the IFN-gamma activated site which also binds the STAT1 homodimer. However, lovastatin did not inhibit IFN-gamma-mediated induction of the Y701 phosphorylated form of STAT1. But lovastatin does inhibit the IFN-gamma-mediated phosphorylation of ERK1/ERK2 (T202/Y204) and S727 phosphorylation of STAT1. TNF-alpha does not induce phosphorylation of ERK1/ERK2 and S727 in ECV304 and smooth muscle cells. The results provide the evidences that statins may have beneficial effects by inhibiting IFN-gamma action in atherosclerotic process

BACKGROUND: It is known that propofol protects myocardium against a global ischemia-reperfusion injury in the isolated rat heart model. The aim of this study was to investigate whether propofol, at a clinically relevant concentration infused during the peri-ischemic period, also provides a protective effect against a regional myocardial ischemia-reperfusion injury in vivo. METHODS: Rats were subjected to 25 minutes of coronary artery occlusion followed by 24 hours of reperfusion. Propofol or intralipid was administrated during 35 minutes starting 5 minutes before the onset of ischemia until 5 minutes after the onset of reperfusion. A micromanometer catheter was advanced into the left ventricle and the hemodynamic function was evaluated. The infarct size was determined by triphenyltetrazolium staining after 24 hours of reperfusion. RESULTS: Propofol administration during the peri-ischemic period demonstrated protective effects on hemodynamic function and infarct size reduction. In the control group, the peak rate of the ventricular pressure increase (+dP/dt(max))(P = 0.0001) and the peak rate of the intraventricular pressure decline (-dP/dt(max))(P = 0.0001) were significantly decreased compared to the sham group. In the propofol group, the +dP/dt(max) (P = 0.003) and -dP/dt(max) (P = 0.002) were significantly improved compared to the control group. The infarct size was 47.6% of the area at risks in the control group, and was reduced markedly by administration of propofol during the peri-ischemic period to 26.2% in the propofol group (P = 0.004). CONCLUSIONS: Propofol, at a clinically relevant concentration infused during the peri-ischemic period, have protective effect after regional myocardial ischemia-reperfusion injury in an in vivo rat heart model.

Lithium has been established as a drug useful for the treatment of manic depressive disorder. It is now well recognized that long-term administration of this drug is associated with various antithyroid effects such as goiter, and subclinical and overt hypothyroidism. However, it has been associated less commonly with thyrotoxicosis. Recently we experienced a case of thyroitoxicosis during lithium therapy. A 24-year-old man treated with lithium carbonate 900 mg-1,200 mg/day for manic-depressive illness for four weeks. He then complained of nervousness, palpitation, tremor, heat intolerance, and sweating. Neck pain was not noted. At that time the results of thyroid function test were consistent with hyperthyroidism: T3 568.8 ng/dL, TSH 0.01 mU/mL, FT4 6.0 ng/dL, but 24 hr radioiodine uptake was 0.3%. We suspected this case as lithium induced thyrotoxicosis and discontinued lithium administration. After discontinuation of lithium thyrotoxic symptoms were subsided. One month later, thyroid hormon levels became normalized: T 100.2 ng/dL, TSH 0.06 mU/mL, FT4 0.97 ng/dL and 24hr radioiodine uptake was 16%. We report this case with review of literatures.

Papillary thyroid carcinoma (PTC) is the most common type of thyroid malignancy and has relatively favorable prognosis. Blood-borne metastases of PTC are very rare among the thyroid malignancies. Moreover a case of blood-borne central nervous system metastasized PTC with only unilateral Horner's syndrome, and without any abnormalities in laboratory or physical examinations has not been described before. A 53-year-old female patient had been managed in ophthalmologic clinic due to vague symptoms of right monocular blurred vision with eye dryness for 3 months, but showed no signs of improvement. So it was performed a magnetic resonance imaging and magnetic resonance angiography to evaluate the possibilities of cerebral lesion. And a left frontal mass was incidentally found, and the tumor turned out to be a PTC that had metastasized to brain, regional lymph node, cervical, thoracic spine, and lung. We describe a PTC with extraordinary initial symptoms that metastasized to an unusual site. We recommend that if a papillary thyroid tumor with unusual symptoms or at an advanced stage is found, further investigation should be performed for distant metastasis.

OBJECTIVES: In this study, we investigated the biodegradation features of 4 perfluorooctanesulfonate (PFOS) alternatives developed at Changwon National University compared to those of PFOS. METHODS: Biodegradation testing was performed with microorganisms cultured in the good laboratory practice laboratory of the Korea Environment Corporation for 28 days following the Organization for Economic Cooperation and Development guidelines for the testing of chemicals (Test No. 301 C). RESULTS: While C₈F₁₇SO₃Na, PFOS sodium salt was not degraded after 28 days, the 4 alternatives were biodegraded at the rates of 20.9% for C₁₅F₉H₂₁S₂O₈Na₂, 8.4% for C₁₇F₉H ₂₅S₂O₈Na₂, 22.6% for C₂₃F₁₈H₂₈S₂O₈Na₂, and 23.6% for C₂₅F₁₇H₃₂O₁₃S₃Na₃. CONCLUSIONS: C₂₅F₁₇H₃₂S₃O₁₃Na₃, C₂₃F₁₈H₂₈S₂O₈Na₂, and C₁₅F₉H₂₁S₂O₈Na₂ were superior to PFOS in terms of biodegradation rates and surface tension, and thus they were considered highly applicable as PFOS alternatives. Environmental toxicity, human toxicity, and economic feasibility of these compounds should be investigated prior to their commercialization.

Traumatic anterior dislocation of the hip is rare. Bilateral traumatic anterior dislocation is an even rarer injury; indeed, only 5 cases have been reported in the English literature. We describe a case of a bilateral traumatic anterior dislocation of the hip and a concomitant unstable lumbar burst fracture following a mechanism of injury distinctly different from other reports.
