BACKGROUND: There is controversy over whether aerobic or resistance exercise is more effective for improving endothelial function in type 2 diabetes mellitus (T2DM). This study was aimed to investigate the effects of an aerobic and resistance training program on endothelial function, and the influences of glycemic control, body weight changes, and aerobic capacity in T2DM. METHODS: Total 40 overweight women with T2DM were assigned into 3 groups: an aerobic exercise group (AEG, n=13), resistance exercise group (REG, n=12), and control group (CG, n=15), and followed either brisk walking for the AEG or resistance band training for the REG, 60 minutes per day, 5 days per week for 12 weeks with monitoring daily activity using accelerometers. We assessed endothelial function by flow-mediated dilation (FMD), and aerobic capacity by oxygen uptake at anaerobic threshold (AT_VO2) at baseline and following training program. RESULTS: The mean participants' age was 57.0+/-6.8 years, and body mass index (BMI) was 27.0+/-2.3 kg/m2. After intervention, FMD increased by 2.2+/-1.9% in AEG, which differed from REG and CG (P=0.002), despite of decreased body weight (BW) in both AG and RG (2.8+/-2.5%, P=0.002; 1.6+/-2.0%, P=0.017, respectively). A significant increased AT_VO2 and decreased HbA1c were found only in AEG. In all participants, FMD was changed with the significant relations to the AT_VO2 (r=0.348, P=0.035), but not to HbA1c levels or BW. CONCLUSION: Aerobic exercise appears to be more beneficial than resistance exercise for improving endothelial function in T2DM. In addition, aerobic capacity could be a better predictor of changes in FMD than BW and glycemic control.

BACKGROUND: Aerobic exercise can effectively reduce visceral fat. However, few studies have examined the effect of daily physical activity on obesity and cardiopulmonary function in the subjects with diabetes. We examined the effect of moderate intensity of walking in obese diabetes patients by monitoring of daily activity and measuring the change in abdominal fat area, muscle are and maximal muscle strength. METHODS: We randomly assigned 27 obese women with type 2 diabetes to an aerobic exercise group (AG, n = 13) and control group (CG, n = 14). The AG performed moderate intensity walking for 60 minutes per exercise, 5 times per week, and for 12 weeks. The activity energy expenditure was monitored by a multi-record accelerometer. The CG maintained routine daily activities. At the time of the initiation of the study and after 12 weeks of exercise, the aerobic exercise capacity was assessed using oxygen consumption rate at anaerobic threshold (VO2-AT). The abdominal fat area and the quadriceps muscle area were measured by computed tomography, and the maximum muscle strength of the upper and lower limbs was measured by a chest press and a leg press, respectively. RESULTS: The mean age of the study subjects was 56.6 +/- 8.0 years, the mean duration of diabetes was 6.3 +/- 6.0 years, and the body weight index (BMI) was 27.3 +/- 2.7 kg/m2. The BMI of the AG was significantly decreased (P = 0.003). In the AG, the visceral fat area and subcutaneous fat area were also significantly decreased (P = 0.018 and P < 0.001, respectively) but not in CG. VO2-AT of the AG was significantly improved, while that of the CG did not change (P = 0.009 and P = 0.115, respectively). The quadriceps muscle mass and the maximal muscle strength of the AG did not change, however, the CG showed a significant decrease. Duration of moderate intensity exercise was correlated with the decrease in total abdominal fat area (r = -0.484; P = 0.011) and that of high intensity exercise was correlated with improvement of cardiopulmonary function (r = 0.414; P = 0.032). CONCLUSION: Daily moderate intensity aerobic exercise is effective at reducing abdominal fat mass, while high intensity exercise improves cardiopulmonary function.

PURPOSE: To compare the results of two different instruments made of stainless steel and titanium alloy for correction of single thoracic adolescent idiopathic scoliosis (AIS) using pedicle screw instrumentation. MATERIALS AND METHODS: A total of 141 patients with single thoracic AIS treated with pedicle screw instrumentation and selective thoracic fusion were retrospectively reviewed after a follow-up of 2 years. The patients had a main thoracic curve of 40° to 75° and were divided into two groups based on instrument materials; S group (stainless steel, n=90) and T group (titanium alloy, n=51). The diameter of the stainless steel rod used was 7.0 mm while that of the titanium alloy rod was 6.35 mm or 6.0 mm. Standing long-cassette radiographic measurements including various coronal and sagittal parameters for the preoperative, early postoperative and 2-year postoperative follow-up were analyzed. There were no significant differences in the preoperative curve characteristics between the two groups. RESULTS: In the S group, the preoperative main thoracic curve of 51.3°±8.4° was improved to 19.0°±7.6° (63.1% correction) and the lumbar curve of 32.3°±8.4° spontaneously decreased to 12.7°±8.2° (62.9% correction) at 2 years postoperatively. In the T group, the preoperative main thoracic curve of 49.5°±8.4° and the lumbar curve of 30.3°±8.9° was improved to 18.8°±7.4° (62.2% correction) and 11.3°±5.4° (63.3% correction), respectively. The corrections of coronal curves were not statistically different between the two groups (p>0.05). The thoracic kyphosis was changed from 16.8°±8.5° to 24.3°±6.1° in the S group and from 19.6°±11.2° to 26.6°±8.5° in the T group. There were no significant differences in the changes of sagittal curves, coronal and sagittal balances at the 2-year follow-up and the number of fused segments and used screws between the two groups (p>0.05). CONCLUSION: When conducting surgery for single thoracic AIS using pedicles screw instrumentation, two different instruments made of stainless steel and titanium alloy showed similar corrections for coronal and sagittal curves.

Background: Lipomas are benign soft tissue neoplasms of mature adipose tissue commonly occurring in the trunk or extremities. But, intraoral lipomas are rare entities which may be only noticed during routine dental examinations. Especially intramuscular lipomas on the tongue have been reported very rarely. In this study, we report a case of intramuscular lipoma on tongue, with a review of the literature from 1978 to 2019, providing data on age, gender, location, presenting symptoms, size, surgical methods, and recurrence.Case presentationA case of intramuscular lipoma occurring in tongue region in a 65-year-old male is reported. Surgical excision is the mainstay of treatment for the lesion. In order to decrease the deformity and discomfort after the excision, we tried to modify surgical technique using enveloped mucosal flap. This technique provided more comfortable healing procedure on the operative site without recurrence. Conclusion This is a rare case of large intramuscular lipoma on tongue. Surgical excision with enveloped mucosal flap design was performed to diminish postoperative raw surface and discomfort and a 24-month follow-up showed excellent healing without any recurrence. A case of intramuscular lipoma on tongue and relevant literature reviews are presented in this study.

OBJECTIVE: The aims of this prospective study were to investigate temporal changes in mood status and distress level, as well as the development of depression, during pegylated interferon (PEG-IFN)-based treatment of patients with chronic hepatitis C (CHC). We also explored whether baseline demographic, psychiatric, and personality traits predicted the evolution of depression. METHODS: CHC patients without depression were screened with laboratory tests; psychiatric interviews; and evaluations of mood symptoms, level of distress, and personality traits. A total of 67 treatment-naïve patients with CHC were consecutively treated with PEG-IFN-α-2a plus ribavirin for 48 (genotype 1, n=29) or 24 (genotype 2, n=38) weeks. Patients were followed prospectively every 4 weeks during the treatment period. RESULTS: Seven patients (10.4%) were diagnosed with major depressive disorder (MDD), and eight (11.9%) developed subsyndromal depression. Times to onset of MDD and subsyndromal depression were 6.67±5.01 and 11.11±5.58 weeks, respectively, after initiation of treatment. Patients who developed MDD had significantly increased fatigue and anxiety and poor psychological well-being during the course of treatment. Pretreatment subthreshold mood symptoms were a significant predictor of depression. CONCLUSION: An early psychiatric assessment may be helpful in improving psychological well-being in those with CHC, leading to adherence to PEG-IFN-based treatment.

BACKGROUND: To assess the effect and toxicity of low-dose paclitaxel in patients with metastatic or recurrent gastric cancer with measurable lesions as first-line chemotherapy. METHODS: Patients with measurable metastatic or recurrent gastric cancer were eligible in this study. Paclitaxel and cisplatin were intravenously infused for 3h, at a dose of each 135 mg/m2 and 60 mg/m2, every 3 weeks and then this regimen was repeated until intolerable toxicity or disease progression. Objective tumor responses, duration of response, time to disease progression, and toxicity profile were evaluated in this study. RESULTS: Total 31 patients were enrolled in this study between May 2001 and January 2004. Sixteen patients had ECOG performance status (PS) 1, eleven had PS 2 and four had PS 3. A total of 122 cycles (median 3, range 1~12) were administered. Eleven (35%, 11/31) objective partial responses (PR) were observed and the remaining 19 patients showed stable (9 patients, 30%) and progressive disease (11 patients, 35%). The response rate was 35% (95% confidence interval, 18~51%). The estimated median survival was 8.1 months, median response duration was 5.3 months and median progression-free survival was 3.3 months. Severe toxicities were uncommon. There were 14 episodes (11.5%) of grade 3-4 neutropenia. Grade 3 nausea and vomiting occurred in 4%. Grade 3 peripheral neuropathy occurred in 3.3%. CONCLUSION: This low dose paclitaxel regimen (135 mg/m2) showed comparable results with previously published high-dose paclitaxel regimen (175~250 mg/m2) used in metastatic or recurrent gastric cancer and the toxicity was minimal.

Bronchial carcinoid tumors are uncommon, constituting approximately 5% of all primary lung cancers. Carcinoid tumors belong to the calss of neuroendocrine tumors that consist of cells that can store and secrete neuramines and neuropeptides. Neuroendocrine tumors of the lung include three pathologic types: a low-grade malignancy, the so-called "typical carcinoid", a more aggressive tumor, the "atypical carcinoid" and the most aggressive malignant neoplasm, the small-cell carcinoma. Atypical carcinoid tumor, have a higher malignant potential, is more commonly peripheral than is the typical carcinoid tumor. Histologic features would characterize a carcionoid as hitologically atypical: increased mitotic activity, pleomorphism and irregularity of neuclei with promonent nucleoli, hyperchromatin, and abnormal nuclear-cytoplasmic ratio, areas of increased cellularity with disorganization of architecture, and areas of tumor necrosis. Metastatic involvement of regional lymph nodes and distant organ is common. The prognosis is related to size of the tumor, typical or atypical appearance, endoluminal or extraluminal growth, vascular invasion, node metastasis. Pulmonary resection is the treatement of choice for bronchial carcinoid. We experienced one case of bronchopulmonary atypical carcinoid tumor. In the case, radiologic study showed solitary lung mass with liver metastasis and the level of 5-HIAA was elevated. There was no history of cutaneous flushing, diarrhea, valvular heart disease. The authors reported a case of brochopulmonary atypical carcinoid tumor with review of literatures.

PURPOSE: The aim of this study was to evaluate the usefulness of a method for positioning the femoral stem in neutral position refer to the measured value of "lateral distance" in pre-operative templating and the femoral stem position post-operatively. MATERIALS AND METHODS: A total of 81 hips in 76 patients underwent cementless total hip arthroplasty between March 2008 and April 2012 using the C2 stem (Lima Corporate S.P.A, Udine, Italy). We measured the perpendicular distance from the lateral outermost part of the greater trochanter to the lateral outermost part of the femoral stem (lateral distance, LD) in pre-operative templating. We aimed to insert the femoral stem in neutral position by comparing LD measured intra-operatively. We evaluated the position of the femoral stem on post-operative plain radiography. We compared the result of post-operative re-measurement of the LD with that of pre-operative measurement. RESULTS: In all of the 81 cases, the femoral stem was inserted in neutral position, defined as the femoral stem position within 3degreesvalgus or varus. The average angle of the inserted femoral stem was 1.20degrees(0.003-2.85degrees). LD measured in preoperative templating was 15.6 mm(10-21.5 mm), and it showed no correlation ratio with LD; LD re-measured post-operatively was 15.9 mm(10.3-23.5 mm) (P=0.781). CONCLUSION: Measuring LD pre-operatively and using the value intra-operatively is an effective method for insertion of the femoral stem in neutral position.
