PURPOSE: The purpose of this study was to measure the bone mineral density (BMD) of the proximal tibia, lumbar spine and proximal femur and to determine out their correlations with the knee alignment in knee osteoarthritic (OA) patients. MATERIALS AND METHODS: The study involved 203 patients (322 knees) with knee osteoarthritis and who had underwent total knee arthroplasty from July 2005 to September 2006. The BMDs of the proximal tibia, lumbar spine and proximal femur were measured and compared. The knee alignment was checked and its correlation with each BMD was analyzed. RESULTS: The mean BMD of the medial proximal tibia, lateral proximal tibia, lumbar spine and proximal femur were 0.857+/-0.180 g/cm(2), 0.772+/-0.177 g/cm(2), 0.940+/-0.174 g/cm(2), and 0.721+/-0.126 g/cm(2), respectively. The mean knee alignment was 10.2+/-4.7degrees varus and the deformity got severe as the BMD of the lateral proximal tibia, lumbar spine and proximal femur were lower and that of the medial proximal tibia was higher. CONCLUSION: The BMD of the proximal tibia was lower than that of the lumbar spine and higher than that of the proximal femur in patients with knee osteoarthritis. The BMDs of the lateral proximal tibia, lumbar spine and proximal femur were negatively correlated with the degree of varus deformity, but that of the medial proximal tibia was positively correlated.

Focal dystonia of musicians is one of the most disabling problems for professional musicians. It has focal task-specificity, presenting with involuntary flexion or extension of individual fingers when musicians play their instruments. It occurs mostly in pianists, and controversies still exist about the pathophysiology, whether it is caused by motor function disability or by a psychological condition. Although sensorimotor rehabilitation, change in instrument, skill or teacher, and immobilization with brace have been tried as treatment, there is still no definitive treatment. Because botox therapy has been effective in certain cases without irreversible side effects, this could be applied even in professional players. We report a case of focal dystonia of the hand in a professional pianist treated using electromyogram-guided botox injection and a review of the relevant medical literature.

Background: Dual-energy X-ray absorptiometry (DXA) is the most widely used method for evaluating muscle masses. The aim of this study was to investigate the agreement between muscle mass values assessed by two different DXA systems. Methods: Forty healthy participants (20 men, 20 women; age range, 23 to 71 years) were enrolled. Total and regional body compositional values for fat and lean masses were measured consecutively with two DXA machines, Hologic Horizon and GE Lunar Prodigy. Appendicular lean mass (ALM) was calculated as the sum of the lean mass of four limbs. Results: In both sexes, the ALM values measured by the GE Lunar Prodigy (24.8±4.3 kg in men, 15.8±2.9 kg in women) were significantly higher than those assessed by Hologic Horizon (23.0±4.0 kg in men, 14.8±3.2 kg in women). Furthermore, BMI values or body fat (%), either extremely higher or lower levels, contributed greater differences between two systems. Bland-Altman analyses revealed a significant bias between ALM values assessed by the two systems. Linear regression analyses were performed to develop equations to adjust for systematic differences (men: Horizon ALM [kg]=0.915×Lunar Prodigy ALM [kg]+0.322, R2=0.956; women: Horizon ALM [kg]=1.066×Lunar Prodigy ALM [kg]–2.064, R2=0.952). Conclusion Although measurements of body composition including muscle mass by the two DXA systems correlated strongly, significant differences were observed. Calibration equations should enable mutual conversion between different DXA systems.

Stent fracture is a complication following implantation of drug eluting stents and is recognized as one of the risk factors for in-stent restenosis. We present the first case of successfully managing a stent fracture and subsequent migration of the fractured stent into the ascending aorta that occurred during repeat revascularization for in-stent restenosis of an ostium of saphenous vein graft after implantation of a zotarolimus-eluting stent. Although the fractured stent segment had migrated into the ascending aorta with a pulled balloon catheter, it was successfully repositioned in the saphenous vein graft using an inflated balloon catheter. Then, the fractured stent segment was successfully connected to the residual segment of the zotarolimus-eluting stent by covering it with an additional sirolimuseluting stent.

An 80-year old woman suffered from sudden onset of chest pain and dyspnea, and visited the emergency room. She received stent implantation with a biolimus A9-eluting stent (Nobori(R) 3.0x24 mm) at a the mid-portion of the left anterior descending artery 5 months prior to admission. The emergency 5-month follow-up angiogram was performed under the impression of late stent thrombosis. The follow-up angiogram showed subtotal occlusion at the mid-portion of the left anterior descending artery, which was the same segment of previous stent implantation 5 months ago. Immediately after thrombus aspiration with the thrombus aspiration catheter, the optical coherence tomography showed layered appearance of neointimal hyperplasia and neointimal rupture within the previously stented segment. Thus, neointimal rupture within accelerated growth of neointimal tissue was observed within a relatively shorter period (i.e., about 5 months) after stent implantation.

PURPOSE: Plasma adiponectin concentrations are inversely related with metabolic syndrome (MetS), and MetS is associated with increased risk for heart failure (HF). However, the relationship between adiponectin and MetS in HF remains undetermined. Therefore, we tested whether MetS was associated with the degree of plasma adiponectin concentrations in HF patients. MATERIALS AND METHODS: One hundred twenty eight ambulatory HF patients with left ventricular ejection fraction of <50% (80 males, 61.8+/-11.9 years old) were enrolled for this cross-sectional study. Echocardiographic measurements were performed, and plasma concentrations of adiponectin, lipoproteins, apolipoproteins (apoB, apoA1) and high sensitive C-reactive protein (hsCRP) were measured. RESULTS: Adiponectin concentrations in HF patients with MetS (n=43) were significantly lower than those without MetS (n=85) (9.7+/-7.0 vs. 15.8+/-10.9 microg/mL, p=0.001). Higher concentrations of apoB (p=0.017), apoB/A1 ratio (p<0.001), blood urea nitrogen (p=0.034), creatinine (p=0.003), and fasting insulin (p=0.004) were observed in HF patients with MetS compared with those without MetS. In HF patients with MetS, adiponectin concentrations were negatively correlated with hsCRP (r=-0.388, p=0.015) and positively correlated with the ratio of early mitral inflow velocity to early diastolic mitral annular velocity, E/E' (r=0.399, p=0.015). There was a significant trend towards decreased adiponectin concentrations with an increasing number of components of MetS (p for trend=0.012). CONCLUSION: Our study demonstrated that adiponectin concentrations decreased in HF patients with MetS, and that relationship between adiponectin, inflammation and abnormal diastolic function, possibly leading to the progression of HF.

OBJECTIVE: Previous studies have shown that fenofibrate therapy increases serum creatinine level and that there is a return of serum creatinine to baseline level after the discontinuation of the drug. We evaluated the effect of long-term fenofibrate therapy on creatinine levels and its reversibility in patients with hypertension and hypertriglyceridemia. METHODS: This retrospective study enrolled 54 hypertensive and hypertriglyceridemic patients taking fenofibrate for 3–6 years (Fenofibrate group) and 30 control patients with similar age, sex, follow-up duration, and creatinine levels (Control group). In 23 patients taking fenofibrate with low triglyceride level and/or with high creatinine levels, fenofibrate was discontinued, and creatinine levels were measured after 2 months. RESULTS: Creatinine levels increased in both the fenofibrate group (from 0.91±0.18 mg/dL to 1.09±0.23 mg/dL, p < 0.001) and the control group (from 0.94±0.16 mg/dL to 0.98±0.16 mg/dL, p=0.04) compared to baseline. However, the elevation was more pronounced in the fenofibrate group than in the control group (21.1±15.4% vs. 4.5±11.3%, p < 0.001). The discontinuation of fenofibrate lowered creatinine levels (from 1.39±0.32 mg/dL to 1.15±0.24 mg/dL, p < 0.001) which were still higher than pre-treatment levels (p=0.013). CONCLUSION: Long-term fenofibrate therapy significantly increased creatinine levels in hypertensive and hypertriglyceridemic patients. The effect of fenofibrate on creatinine level was partially reversible. This finding suggests that follow-up creatinine level is necessary with fenofibrate therapy.
