PURPOSE: The purpose of this study is to compare CO2 DSA and nonionic contrast media angiography in respect to the quality of the opacification of collaterals and incidence of side-effects in peripheral occlusive arterial disease. MATERIALS AND METHODS: Sixteen patients who were suspected to have peripheral occlusive arterial disease were performed angiography with nonionic contrast media and CO2 at the same location with the same catheter. The causes of the lesions were atherosclerosis(n=7) and Buerger's disease(n:9). CO2 DSA was compared with nonionic contrast media angiography in respect to the quality of image in the diagnosis of the lesions, opacifications of collaterals and side-effects. RESULTS: In atherosclerosis;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 6 patients and was poor in 1 patient;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 5 patients and was poor in 2 patients. In Buerger's disease;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 2 patients and was poor in 7 patients;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 1 patient and was poor in 8 patients. Leg pain was the only side-effect after CO2 injection occuring in 4 out of 16 patients. CONCLUSION: CO2 could be used as safe contrast media in patient with risk factors for nonionic contrast media and for diagnosis of the atherosclerosis in lower extremity. For the procedures such as vascular intervention reguiring large amount of contrast media CO2 could effectively replace nonionic contrast media.

Amicrobial pustulosis of the folds (APF) is a rare pustular eruption, which predominantly involves the cutaneous folds, including the external auditory canals, scalp, and palms. It occurs in patients with a wide spectrum of autoimmune abnormalities. Systemic lupus erythematosus is the autoimmune disorder observed most commonly in patients with APF. The etiology of APF is unclear, but all reported cases have involved women of reproductive age when the eruptions first occurred. This report describes a 34-year-old woman who presented with an acute pustular rash. Her medical history was unremarkable, except for transitory dry eyes, dry mouth, and polyarthralgia for 1 year. Coalescing pustular lesions arising on erythematous skin, forming crusted and eroded plaques, were observed, which predominantly affected the anterior chest, mainly the cutaneous folds. The periorificial regions were also involved, including the nasal alae, mouth angles, and external auditory canals. Our patient had the characteristic clinical and histopathological features of APF, in association with primary Sjogren's syndrome (pSS). In conclusion, we present a patient having APF associated with pSS.

Actinomycosis is an uncommon chronic infectious disease caused by Actinomyces. There are three distinct forms of the condition, namely cervicofascial, thoracic, and abdominal; the hepatic variety is an unusual form of abdominal actinomycosis, accounting for about 15% of cases of this type. Many reports of actinomycosis have been published, but few have detailed the MR findings of hepatic actinomycosis. We describe the contrast-enhanced CT and MR findings in one case of hepatic actinomycosis.

PURPOSE: To evaluate characteristic MR findings of craniocerebral anomaly and its relationship with neurologic manifestations. MATERIALS AND METHODS: We retrospectively reviewed MR images of 36 patients with craniocerebral anomaly diagnosed by MRI and clinical courses. We correlated the characteristic MR findings in 41 lesions with neurologic manifestastions focusing on seizures and developmental delay. RESULTS: Twenty-three patients with seizures consisted of 14 patients(60%) with neuronal migration disorders and seven(30%) with phakomatosis, among which 18 patients(78%) had generalized type of seizures. Locations of the lesions were the parietal lobes in 11 patients(52%) and the subependymal or periventricular regions in seven(33%). Two patients with tuberous sclerosis had the lesions in both parietal and subependymal areas. Nine patients had the signs of developmental delay that were seen in the four(44%) with schizencephaly, two (22%) with tuberous sclerosis, two(22%) with heterotopia, and one(ll %) with pachygyria. CONCLUSION: Neuronal migration anomaly was relatively common lesion that presented neurologic manifestations such as seizures and developmental delay. Generalized type of seizures was common. We were able to diagnose these anomalies using the MRI that helped establish therapeutic plans.

PURPOSE: To assess the usefulness of three-dimensional spiral CT angiography in the diagnosis and as a guide for the treatment of arteriosclerosis obliterans of the lower extremity. MATERIALS AND METHODS: During a recent one-year period, CTA and conventional angiography were performed in 12 patients with suspected ASO. From the upper margin of the third lumbar vertebral body to below the knee joint, helical CT scanning was performed 30-45 seconds after the injection of Ultravist 370(150-180ml) by a power injector at the rate of 2.5-3.0ml/sec via the antecubital vein. The resulting data were reformatted by SSD after reconstruction of 5mm intervals, and CTA was compared with CA for site and degree of stenotic or occlusive lesion. RESULTS: On CTA and CA, twenty-three occlusive lesions above the tibioperoneal artery were detected in 12 patients. On CA, three mild seven moderate and eight severe stenoses were seen, as well as five occlusions. There were three cases of overgrading and three of undergrading. Overall diagnostic accuracy was 73.9%(17/23). Calcifications were detected at on axial CT scanning in the two of three underestimated lesions. Migration of the thrombi was noted in one case. CONCLUSION: CTA may be useful in the evaluation of the arteries of the lower extremities, and valuable in the planning and follow-up of treatment.

BACKGROUND: Regular exercise improves glycemic control and exercise capacity. However, 47.5% of Korean patients with type 2 diabetes do not take part in exercise at least once a week. A recommendation to accumulate 10,000 steps throughout the day has many advantages. The purpose of this study was to investigate the effects of increasing the number of walking steps per day on glycemic control and exercise capacity using a pedometer in newly diagnosed type 2 diabetics who did not take part in exercise at least once a week. METHODS: We included twenty nine Korean type 2 diabetic patients aged 46-62 years who presented with newly diagnosed type 2 diabetes and did not take part in exercise at least once a week. They were encouraged to walk more than 10,000 step/day and the daily steps were recorded using pedometers. A gradual loading exercise test was administered, with an electric stationary upright cycle ergometer, to estimate the rate of oxygen consumption (VO2), exercise time, load and metabolic equivalent (MET) before and after 12 weeks of walk training. Before and after the intervention, metabolic and lipid profiles and aerobic exercise levels were evaluated for all subjects. Subject descriptive comparisons were made with paired t-tests. The Pearson's correlation coefficients were calculated as well to analyze the linear relationship among variables. RESULTS: The results showed that the number of steps per day were increased to about 10,000 steps per day (p<0.001). Body mass index (p<0.001), abdominal circumference (p=0.011), aerobic exercise capacity level and glycemic control were significantly improved (p<0.001). However, lipid profiles were not affected during the exercise intervention. There was a positive correlation between increases in steps per day and changes of aerobic capacity such as peak VO2 (r=0.46, p<0.05). Also, increases in steps per day were negatively correlated with changes in HbA1c (r=-0.711, p<0.001). CONCLUSIONS: This study suggests that both glycemic control and aerobic capacity are improved with increasing the number of steps to over 10,000 steps per day in newly diagnosed Korean type 2 diabetics. Our result suggest that a pedometer may be used as a simple and effective method of encouraging physical activity to type 2 diabetics who did not take part in exercise at least once a week.

STUDY DESIGN: To examine the factors considered in the selection of therapeutic methods, and the methods for accessing postoperative clinical outcomes, in degenerative lumbar spondylolisthesis. OBJECTIVES: In this retrospective study, patients who had taken only posterolateral fusion, and with a posterior lumbar interbody fusion, were evaluated. The analyses of the pre- and post-operative factors associated with the clinical outcomes of the surgery for degenerative lumbar spondylolisthesis were also performed. MATERIALS AND METHOD: Of the patients who had received the surgery for degenerative lumbar spondylolisthesis, between January 1995 and December 2000, there were 59 for whom follow-up observations were possible, and these were selected for the present study. The patients were comprised of 19 males and 40 females, with ages ranging from 42 to 74 years (58.4+/-8.4 years old). Of the 59 patients, 39, and 20, received a posterolateral fusion, or both a posterolateral fusion and a posterior lumbar interbody fusion, respectively. In the present study, the pre-operative factors considered were the surgical method, sex, age, L1 axis S1 distance (LASD), lordosis angle and the degree and duration of spondylolisthesis, with the degree of fusion, the lordosis angle of the fused body, the lordosis angle at the final follow-up and the lordosis angle of the fused body at the final follow-up, used as the post-operative factors. Each factor was statistically tested to see if it had a significant correlation with clinical outcomes (Recovery rate by Hirabayashi's method). A value of P < 0.05 was considered as being statistically significant. RESULT: The posterolateral fusion group showed a significantly lower recovery rate with an LSAD over 35 mm, a degree of spondylolisthesis over 10 mm and a pre-operative lordosis angle under 20 degrees, indicating that an additional posterior lumbar interbody fusion would provide a good clinical outcome. At the final follow-up, both groups showed significantly lower recovery rates with a lumbar lordosis angle under 20 degrees, and the posterolateral fusion group showed significantly lower recovery rates when the post-operative lordosis angle of the fused segment was under 18 degrees, and with a lordosis angle of the fused segment was under 18 degrees at the final follow-up. These post-operative factors showed significant correlations with the clinical outcomes. CONCLUSIONS: It is considered that an additional posterior lumbar interbody fusion is indicated in patients with a LSAD over 35 mm, an anterior slippage over 10 mm and a lumbar lordosis angle over 20 degrees. It is also considered that the lordosis angles of the fused segment, and the post-operative lumbar lordosis, are important factors that require peri-operative correction and maintenance.

OBJECTIVE: The purpose of this study was to evaluate the MR spectrum and MR cholangiographic imaging findings of clonorchiasis. MATERIALS AND METHODS: We reviewed 26 patients with confirmed clonorchiasis by either stool tests (n=24) or surgery (n=2). MR imaging was performed on a 1.5 T system (GE Medical Systems, Milwaukee, WI) with a torso coil. Axial T1-and T2-weighted, gadolinium-enhanced dynamic images and MR cholangiography were obtained. Image analyses were used to identify abnormalities of the intrahepatic and extrahepatic bile ducts and the presence of hepatobiliary malignancy. All MR examinations were reviewed by the consensus of two abdominal radiologists. RESULT: Intrahepatic bile duct abnormalities were seen in 23 (89%) of the 26 patients. The most common finding was mild dilatation of the intrahepatic bile duct which was found in 21 (81%). "Too many intrahepatic ducts" were found in 16 (62%), wall enhancement and thickening in 21 (81%) and filling defects and ductal stricture in the intrahepatic bile duct in 6 (24%) and 3 (12%) patients, respectively. Extrahepatic ductal dilation was found in 5 (19%) and 9 (35%) revealed hepatobiliary malignancy. CONCLUSION: MR imaging revealed various findings of clonorchiasis, including dilatation, wall enhancement, stricture of the intrahepatic ducts and filling defect within the intrahepatic bile duct.

PURPOSE: With gold electroforming system for the double crown, the secondary crown is electroformed directly onto the primary crown. An even thick layer of high precision can be acquired. It is thought that the retention of electroformed outer crown is primarily acquired by the adhesive force (surface tension) through the saliva which is interposed between precisely fitted inner and outer crown. The purpose of this study was to investigate the effect of taper and surface area of inner crown on the retentive force of electroformed outer crown according to the presence of saliva. MATERIALS AND METHODS: 32 titanium inner crowns with cervical diameter of 8 mm and cone angles of 0, 2, 4, 6 degrees, which had same surface area by regulated height, were machined on a lathe. Another 32 titanium inner crowns with cone angles of 0, 2, 4, 6 degrees, which had doubled surface area by increased cervical diameter, were fabricated. Eight specimens of each group, for a total of 64 titanium inner crowns, were prepared. The electroformed outer crowns were fabricated directly on the inner crowns by using electroforming machine(GAMMAT free, Gramm Technik, Germany). The tertiary frameworks were waxed-up on the electroformed outer crown and cast using nonprecious alloy(Rexillium(R)III, Jeneric(R)/ Pentronh(R) Inc., USA). The cast metal frameworks were sandblasted with alubimium oxides and cemented using resin cement(Superbond C and B, Sun Medical Co., Japan) over the electroformed copings of each specimen. Then, artificial saliva(Taliva(R), Halim Pharm Co., Korea) was sprayed between the inner and outer crown, and they were connected under 5 kg force. The retentive force was measured by the universal testing machine(Tinius Olsen 1000, Tinius Olsen, USA) with a cross-head speed of 66.67 mm/sec. The direction of cross-head travel was exactly aligned with the path of removal of the respective specimens. This measurement procedures for retentive force of electroformed outer crown with artificial saliva were repeated in the same way without presence of artificial saliva. RESULTS AND CONCLUSION: The following conclusions were drawn: 1. The retentive force of electroformed outer crown was decreased according to increased taper of inner crown(P<.05). 2. The retentive force of electroformed outer crown showed no significant differences according to surface area and the presence of artificial saliva(P>.05).
