BACKGROUND: Steroid myopathy is an unexpected side effect to the prolonged therapeutic use of steroids. To treat steroid myopathy, the followings are recommended; reduction of the steroid dose, usage of a nonfluorinated steroid, and conversion to an alternate day regimen. As muscle loading is encouraged in maintaining normal muscle properties, it is also apparent that physical exercise may be useful in the prevention and treatment of steroid myopathy. METHOD: The experiment was designed to investigate the effects of exercise on steroid myopathy. Rats being treated with triamcinolone acetonide (TA) (5 mg/kg/day) for 7 days exercised on a treadmill (speed 20m/min, 30 min/day, 3 days/week) for 2 weeks. The extensor digitorum longus (EDL) and soleus were then examined histochemically and ultrastructurally. RESULTS: Rats treated with TA showed significant loss of body and muscle weight. In the TA treated group, cross-sectional areas of type II fibers of both EDL and soleus were decreased in comparison with the controls. Necrotic changes were found only in type II fibers of the soleus. Recovery from the weight loss with type II fiber atrophy was more pronounced in the exercise group than that of the sedentary group, but was not significant statistically. Ultrastructural abnormalities, that consisted of subsarcolemmal mitochondrial accumulation, mitochondrial vacuolation, increased number of mitochondria in autophagic vacuoles, and dilatation of sarcoplasmic reticulum, were seen in TA treated muscles. These injuries were significantly reduced by the exercise, however, complete recovery could not be seen. CONCLUSIONS: These results suggest that treadmill exercise for 2 weeks partially ameliorate steroid myopathy in.

The schwannoma is a benign neoplasm originating from Schwann cell. Solitary nerve sheath tumors such as benign schwannomas arising in the pelvic retroperitoneum are infrequently reported. Those tumors can indeed be misdiagnosed for other more common conditions both clinically and instrumentally. We report a very rare case of a benign retroperitoneal pelvic schwannoma of the obturator fossa, which was incidentally found and misdiagnosed as adnexal mass preoperatively in fifty one-years-old postmenopausal women.

Urodynamics is a neurourolgic diagnostic tool concerned with identification and measurement of physiologic and pathologic factors involved in the storage, transportation, and evacuation of urine. It plays an important role in the diagnosis, management of neurogenic bladder and its use has gradually increased. But a disparity between clinical and urodynamic findings is commonly found and its application to the clinical management of neurogenic bladder is practically as well embarrassing as its reading. We analyzed the results of 81 cases of neurogenic bladder with urodynamic study. Urodynamically, there were 18 cases showing D. hyperreflexia with DSD, 10 cases D. Hyperreflexia without DSD, 36 cases D. areflexia without low compliance, and 17 case D. areflexia with low compliance. A disparity between the clinical and urodynamic :assessment was noted in 28 cases( 35%). Clinically severe symptom with complication was particularly common in D. hyperreflexia with DSD, D. areflexia with low compliance and catheter indwelling patients.

BACKGROUND: It has been suggested that clearance of HBeAg was usually durable in Caucasians with chronic hepatitis B (CHB) after cessation of lamivudine, but little is known whether such effect is durable in Asian patients. The aim of this study was to evaluate the therapeutic efficacy of lamivudine, the predictive factors for response (defined as clearance of both HBV-DNA and HBeAg) and relapse rate in patients with CHB. METHODS: We retrospectively analyzed 67 patients with CHB who were treated with lamivudine from August 1996 to September 1997. Among them, 41 were non-responders to interferon alpha. Lamivudine was given at a dose of 150 mg a day over 6 months. In responders, lamivudine was continued between 2 and 4 months more after clearance of HBeAg and they were followed for 12 months without further treatment. Mean duration of therapy in responders and non-responders was 8.9 months (range; 6-13 months) and 11.6 months (range; 7-22 months) respectively. RESULTS: 51 (79.1%) cleared serum HBV-DNA, 31 (46.3%) cleared both serum HBV-DNA and HBeAg, and 25 patients (37.3%) were seroconverted to anti-HBe. Predictive factors for response were female, high levels of serum ALT and low levels of serum HBV-DNA. However, during follow-up in responders, the cumulative relapse rate was 64% at 12 months. CONCLUSION: Although lamivudine effectively suppressed HBV replication, relapse rate was high even in responders. It is suggested that the response to lamivudine is not durable in Korean patients with CHB.

Bone scan is one of the most frequently performed studies in nuclear medicine with few adverse reactions for the examination of pathologic conditions of bone. Diffuse liver uptake of Technetium-99m methylene diphosphonate (Tc-99m MDP) is a rare occurrence with only a few reports in the literature. Furthermore, there is no report of Tc-99m MDP-induced liver injury. Here we report a case of acute hepatitis with diffusely increased uptake of Tc-99m MDP in a hemodialysis patient.

Urinary biomarkers of acute kidney injury (AKI) have been revealed recently to be useful for prior prediction of AKI. However, it is unclear whether these urinary biomarkers can also detect recovery from established AKI. Urinary biomarkers, including neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C, were measured every 2 days for 8 days in 66 patients with AKI. At day 0, there were no significant differences in plasma creatinine, BUN, and urine cystatin C between AKI patients in the recovery (n = 33) and non-recovery (n = 33) groups. Plasma creatinine concentrations were significantly lower in the recovery group (3.0 +/- 2.0 mg/dL) than in the non-recovery group (5.4 +/- 1.9 mg/dL) on day 4 after AKI diagnosis (P < 0.001). In contrast, there were significant differences in urine NGAL between the two groups starting on day 0 (297.2 +/- 201.4 vs 407.6 +/- 190.4 ng/mL, P = 0.025) through the end of the study (123.7 +/- 119.0 vs 434.3 +/- 121.5 ng/mL, P < 0.001). The multiple logistic regression analysis showed that urine NGAL could independently predict recovery from AKI. Conclusively, this prospective observational study demonstrates that urine NGAL can be a highly versatile marker for early detection of the recovery phase in established AKI patients.

OBJECTIVE: To evaluate the clinical significance of fetal choroid plexus cysts (CPCs) in the second trimester, especially an association with trisomy 18. METHODS: From March 1998 through June 1999, second trimester screening ultrasonography was performed on 4,948 unselected single-ton pregnancies. CPCs were noted in 132 fetuses. Among them, detailed ultrasonography and follow-up was possible in 119 cases and they were recruited into the study. There were 91 cases of isolated CPCs and 28 cases of CPCs in high-risk population. "Isolated CPCs" were defined as: mother did not have any risk factors requiring amniocentesis and there were no other sonographic abnormalities on detailed ultrasound. "CPCs in high-risk population" were defined as: mother had any risk factor requiring karyotyping or there were any other sonographic abnormalities although she was general population. Amniocentesis was performed in 39 cases. We compared gestational age at time of detection, size, bilaterally, multiplicity, and complexity of CPCs in the group of isolated CPCs and CPCs in high-risk population (t-test, chi-square test; P<0.05). We evaluated the findings of detailed and follow-up ultrasonography, karyotypes, and final outcomes of pregnancy. RESULTS: Gestational age at time of detection was not different in both groups of isolated CPCs and CPCs in high-risk population (19+/-2 vs 18+/-1 wk, p>0.05). Mean size (6.4 vs 6.2 mm), bilaterality (60% vs 57%), multiplicity (66% vs 57%), and complexity (8% vs 14%) of CPCs were also similar. All CPCs were disappeared irrespective of size and mean time of disappearance was 25+/-3 and 26+/-3 week, respectively (p>0.05). All cases of isolated CPCs resulted in phenotypically-normal neonates. It was confirmed by either amniocentesis or postnatal examination by the pediatrician. Among fetuses having CPCs in high-risk population, two trisomy 18 and one trisomy 21 were detected. All of them had positive result of maternal serum marker test and/or sonographic abnormalities. Remaining cases were proved normal. CONCLUSION: The risk of chromosome abnormalities is very high when CPCs are associated with other abnormalities on detailed ultrasound, indicating a clear need to offering genetic amniocentesis. As contrast, the risk of chromosome abnormalities for a case of isolated CPCs is very low, and in this series there was no trisomy 18. Therefore isolated CPCs should be considered as the indication of detailed ultrasound examination, but not routine karyotyping.

PURPOSE: Acute pyelonephritis (APN) is among the most common infectious diseases. Most APN occurs in young women and easily treated. Bacteremia has been associated in approximately 20-30% of those with APN. But recent documents demonstrated that blood cultures provide no useful information toward the clinical management of acute pyelonephritis. Thus we compared demographic and clinical characteristics as related to the bacteremic status, and investigated the risk factors for bacteremia. METHODS: One hundred sixty five patients, who visited myongji hospital for APN from January, 2004 to December, 2006 were included. Retrospective data were analyzed by medical record review. RESULTS: Bacteremic patients (N=51, 30.9%) were significantly older than those in nonbacteremic group (p<0.0001), had elevated serum creatinine (p=0.008), decreased platelet counts (p=0.029), lower serum protein (p=0.010), and lower serum albumin (p=0.011) than those without bacteremia. Hematuria was more severe in bacteremic patients (p<0.0001). The bacteremic cases were observed more frequently in patients with complicated APN patients than uncomplicated patients (46.7% vs. 21.4%, p=0.001). No significant difference existed between the bacteremic and non-bacteremic patients in the prevalence of resistance to quinolone of E. coli. In multivariate logistic regression analysis, serum albumin (p= 0.023), hematuria (p=0.003), and age (p=0.003) at presentation were found to be independent risk factors for bacteremia in acute pyelonephritis. CONCLUSION: Our study reveals that patients with bacteremia have different clinical characteristics compared to those without bacteremia. It is recommended to concern about the presence of bacteremia in the treatment of APN.

We present a case of thrombotic coronary aneurysm of the left anterior descending artery (LAD) presenting with recurrent severe orthopnea in an end stage renal disease patient. She was admitted to the hospital with progressive dyspnea, exertional chest pain, and profound orthopnea. The echocardiography revealed a well marginated mass lesion between the main pulmonary artery and the left atrium. Chest CT showed a space-occupying lesion surrounded by the main pulmonary artery, the left atrium and the appendage adjacent to the atherosclerotic calcified lesion. Coronary angiography confirmed a huge thrombotic aneurysm with total occlusion of the proximal LAD. The presentation and management of the coronary aneurysm was reviewed.
