BACKGROUND: Combination of metformin to reduce the fasting plasma glucose level and an α-glucosidase inhibitor to decrease the postprandial glucose level is expected to generate a complementary effect. We compared the efficacy and safety of a fixed-dose combination of voglibose plus metformin (vogmet) with metformin monotherapy in drug-naïve newly-diagnosed type 2 diabetes mellitus. METHODS: A total of 187 eligible patients aged 20 to 70 years, with a glycosylated hemoglobin (HbA1c) level of 7.0% to 11.0%, were randomized into either vogmet or metformin treatments for 24 weeks. A change in the HbA1c level from baseline was measured at week 24. RESULTS: The reduction in the levels of HbA1c was −1.62%±0.07% in the vogmet group and −1.31%±0.07% in the metformin group (P=0.003), and significantly more vogmet-treated patients achieved the target HbA1c levels of <6.5% (P=0.002) or <7% (P=0.039). Glycemic variability was also significantly improved with vogmet treatment, estimated by M-values (P=0.004). Gastrointestinal adverse events and hypoglycemia (%) were numerically lower in the vogmet-treated group. Moreover, a significant weight loss was observed with vogmet treatment compared with metformin (−1.63 kg vs. −0.86 kg, P=0.039). CONCLUSION: Vogmet is a safe antihyperglycemic agent that controls blood glucose level effectively, yields weight loss, and is superior to metformin in terms of various key glycemic parameters without increasing the risk of hypoglycemia.

In order to study the treatment of aneurysms, the technique of making experimental aneurysms in laboratory animals must be established. In our study, to examine the feasibility of making experimental aneurysm and selective angiography on the common carotid artery in rabbits and to determine the size of experimental aneurysm after surgery, saccular aneurysms were fashioned on the right common carotid artery in 17 rabbits using a vein pouch technique. Selective angiography of the common carotid artery was performed immediately after surgery, and at 1 week, 4 weeks, and 8 weeks after surgery. Also, histological changes in the aneurysms were observed. In 16 rabbits with established successful experimental aneurysm, no differences were found in diet intake and behavior before and after surgery. The patency of the carotid artery was confirmed by selective angiography. The average size of the aneurysm immediately after surgery was similar to that of 1 week postoperatively in selective angiography, however it increased with time at 4weeks and 8 weeks. Histologically, infiltration of inflammatory cells and hemorrhage were found at the junction of the carotid artery and the vein pouch at 1 week, which disappeared at 4 weeks and 8 weeks. This study suggests experimental saccular aneurysm using the vein pouch technique might form aneurysms similar to that of the human in its properties such as increment of size, and selective angiography might be suitable for assessment of experimental aneurysm. Therefore, this animal model may be suitable for investigating new treatment methodologies for human aneurysms.

A conference was convened by the Korean Diabetes Association and the Korean Endocrine Society on September 7, 2009 to discuss and organize the results of research on intensive glucose control for the prevention of cardiovascular disease in patients with type 2 diabetes. Professor Kyung Soo Park led the conference, and Professors Kwang Won Kim and Ho Young Son acted as chairmen. Professors Doo Man Kim, Tae Sun Park, and Bong Soo Cha reported on intensive glucose control and diabetic complications, including the UK Prospective Diabetes Study (UKPDS), Diabetes Control and Complication Trial (DCCT) research results, the recently published Action to Control Cardiovascular Risk in Diabetes (ACCORD), Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE), and Veterans Affairs Diabetes Trial (VADT) research, as well as meta-analyses. Professor Jeong-Taek Woo reported on the manuscript written by the committee for the Korean Diabetes Association which dealt with the treatment of diabetes mellitus. Professors Kyung Soo Ko, Joong Yeol Park, Hyun Shik Son, Moon-Kyu Lee, Dong-Won Byun, and Yoon-Sok Chung participated in the discussion and collected information for the manuscript from all of the participants. The aim of the debate was to determine how to establish target goals for intensive glucose control and how to individualize those goals. The participants concluded that there was no need to modify the recommendation of maintaining an HbA1c under 6.5%, the current blood glucose treatment goal that is recommended by the Korean Diabetes Association. In addition, individual target goals for glucose control were recommended depending on the situation of each patient. We report on the consensus statement from the meeting.

BACKGROUND: It is known that chronic sustained hyperglycemia and its consequent oxidative stress causes diabetic complication in type 2 diabetes. It has been further proven that glycemic variability causes oxidative stress. The aim of this study is to measure the average daily risk range (ADDR)-index of glycemic variability, and to evaluate relevant variables. METHODS: We measured the blood glucose level of type 2 diabetic patients who were treated with multiple daily injections from January to July, 2008. The blood glucose levels were checked four times a day for 14 days and were conversed according to the ADRR formula. The degree of glycemic variability was categorized into non-fluctuation and fluctuation groups. We collected patient data on age, sex, duration of diabetes, body mass index, HOMA(IR), HOMA(betacell) and HbA1c. RESULTS: A total of 97 patients were enrolled in this study. The mean age, duration of diabetes, HbA1c and mean ADRR were 57.6 +/- 13.4, 11.5 +/- 8.5 years, 10.7 +/- 2.5%, and 26.6 +/- 9.8, respectively. We classified 18.5% of the patients to the non-fluctuation group, and 81.5% to the fluctuation group. ADRR was significantly correlated with duration of diabetes, fasting and postprandial glucose, fructosamine, HbA1c and BMI and HOMAbetacell. In addition, this study confirmed that BMI, HOMAbetacell and HbA1c were ADRR-related independent variables. CONCLUSION: ADRR can be used as an index for blood glucose fluctuation in type 2 diabetic patients. Measuring ADRR in patients with low BMI and a long duration of diabetes is helpful to improve the effectiveness of their care.

BACKGROUND/AIMS: Treatment using multiple daily insulin (MDI) should give diabetic patients many benefits. Nevertheless, few studies have examined the impact of an increased frequency of daily insulin injection on quality of life, anxiety levels, and depression in diabetic patients, and individual's continued compliance with MDI is unclear. This study examined these issues using standardized questionnaires. METHODS: This was a cross-sectional, randomized study. Ninety-nine insulin-treated type 2 diabetic patients (mean age 53.1+/-12 years, mean duration of diabetes 10.3+/-6.5 years) were divided a group (n=50) who injected insulin four times daily (mean age 49.6+/-12.3 years, mean duration of diabetes 6.5+/-6.4 years) and a group (n=49) who injected insulin once or twice daily (mean age 56.4+/-11.6 years, mean duration of diabetes 11.5+/-5.8 years). All patients independently completed the Korean Version of the World Health Organization Quality of Life Scale Abbreviated Version and standardized Hospital Anxiety and Depression Scale for Koreans. RESULTS: No significant differences were evident with respect to age, gender, and duration of diabetes between the two groups (p<0.05). No significant differences were evident in the results of the questionnaires between the two groups, except for the physical health domain (p<0.05). CONCLUSIONS:Multiple daily insulin injections had nearly no influence on quality of life, anxiety levels, or depression in type 2 diabetic patients. Therefore, treatment with MDI should be considered for patients who would benefit from this.

Inflammatory pseudotumor of the lung is considered to be a rare, benign, neoplastic lesion, consisting mainly of spindle mesenchymal cells, sometimes in such a way that its histological appearance mimics that of a spindle cell sarcoma, fibrous histiocytoma or fibrosarcoma. A case of inflammatory pseudotumor of the lung occurring in a 13-year-old boy is reported with pathologic findings, including its ultrastructure. The patient had had no symptoms and accidentally discovered his condition after a chest X-ray examination at a regular school physical check up. The mass was located in the suprahilar area of the left lung. Exploratory thoracotomy revealed a large mass that was removed, together with the left upper lobe of the lung. Microscopically, the mass was composed of numerous interstitial inflammatory cells, mainly lymphoplasma cells. Ultrastructurally, the spindle-shaped mesenchymal cells were arranged haphazadly and the normal pulmonary structure was nearly totally destroyed. Emphasis is given to complete resection of the tumor for both diagnostic and therapeutic purposes.

OBJECTIVE: To observe the ipsilateral upper limb function after stroke comparing proximal with distal part and to determine how they recover after stroke. METHOD: Cohort study of 72 patients with stroke in the middle cerebral arterial territory undergoing multidisciplinary stroke rehabilitation program. The main outcome was assessed by the Manual Function Test (MFT) for upper limb function, weekly. RESULTS: The recovery time of the ipsilateral upper limb to maximum function was 32.4+/-15.4 days. The functions of the ipsilateral shoulder and hand after stroke decreased significantly. Even at the maximum recovery, complete recovery was not seen. For ipsilateral shoulder, more severe functional deficits were seen with subcortical lesion than with cortical lesion, whereas for ipsilateral hands, no difference was seen between them. CONCLUSION: Therefore, the fact that recoveries of the shoulders and hands were different according to the presence of cerebral cortical or subcortical lesions suggests that the brain structures that control these areas or the recovery mechanisms might be different.

OBJECTIVE: We observed the nature of ipsilateral weakness, not hemiplegic side after stroke. And we studied correlation between ipsilateral weakness and neurologic recovery of hemiplegia. METHOD: This study was prospective, follow-up clinical trial. Ipsilateral motor power was checked serially in 20 subjects using Nicholas Manual Muscle Tester (NMMT) (shoulder abduction, wrist extension, hip flexion, ankle dorsiflexion). The subjects are first attacked hemiplegic stroke patients. Other outcome measures are Mini-mental Status Examination (MMSE) and National Institutes of Health Stroke Scale (NIHSS). We studied correlations between motor power recovery in ipsilateral limbs and recovery of neurologic impairment in hemiplegic limbs of stroke patients through SPSS 7.0 program. RESULTS: Ipsilateral motor power in early stage stroke patients is significantly low compared with that of normal subject except ankle dorsiflexion (p<0.05). Comparing ipsilateral proximal with distal limbs power in pre and post multidisciplinary rehabilitation program, upper proximal part recovered faster than the distal part, but which was not statistically significant. Recovery of ipsilateral upper proximal and distal limb weakness is associated with neurologic recovery in hemiplegic side. CONCLUSION: After the stroke, ipsilateral upper limb motor weakness does occur and which follows similar neurologic recovery pattern to the hemiplegic side. Ipsilateral cortical and subcortical tracts take effect on the neurologic recovery of contalateral side.
