Basilic vein transposition is a feasible and a good method to make AVF with autogenous vein. Small incision can be applied to basilic vein transposition, which can be less painful and more comfortable to the patients.
2.Protective effects of kaempferol against cardiac sinus node dysfunction via CaMKII deoxidization.
Anatomy & Cell Biology 2015;48(4):235-243
Kaempferol exerts cardioprotective actions through incompletely understood mechanisms. This study investigated the molecular mechanisms underlying the cardioprotective effects of kaempferol in sinus node dysfunction (SND) heart. Here, we demonstrate that angiotensin II (Ang II) infusion causes SND through oxidized calmodulin kinase II (CaMKII). In contrast to this, kaempferol protects sinus node against Ang II-induced SND. Ang II evoked apoptosis with caspase-3 activation in sinus nodal cells. However, kaempferol lowered the CaMKII oxidization and the sinus nodal cell death. To block the CaMKII oxidization, gene of p47phox, a cytosolic subunit of NADPH oxidase, was deleted using Cas9 KO plasmid. In the absence of p47phox, sinus nodal cells were highly resistance to Ang II-induced apoptosis, suggesting that oxidized-CaMKII contributed to sinus nodal cell death. In Langendorff heart from Ang II infused mice, kaempferol preserved normal impulse formation at right atrium. These data suggested that kaempferol protects sinus node via inhibition of CaMKII oxidization and may be useful for preventing SND in high risk patients.

PURPOSE: The aim of this study was to investigate the radiological characteristics of the osteoarthritis of the second metatarsophalangeal (MTP) and tarsometatarsal (TMT) joint. MATERIALS AND METHODS: Between January 2002 and August 2010, 27 patients (33 feet) who had second metatarsal osteoarthritis (OA) were reviewed retrospectively. Group 1 was 14 patients (17 feet) with second MTP joint OA. Group 2 was 13 patients (16 feet) with second TMT joint OA. Group 3 was 24 patients (25 feet) had hallux valgus without second metatarsal (MT) OA as control. Weight bearing foot anteroposterior (AP) and lateral view were checked, and measured hallux valgus angle, metatarsus adductus angle (MAA), second MT functional length, first and second MT length by Hardy & Clapham method on AP view, angle of second MT with horizontal plane, calcaneal pitch, talo-first MT on lateral view. RESULTS: On weight bearing foot AP view, second MT functional length of group 1, 2, 3 was 2.4 mm, -0.1 mm, 0.7 mm and MAA of group 1, 2, 3 was 17.7degrees, 17.7degrees, 14.5degrees. Second MT functional length of group 1 was longer than control group and it was statistically significant. MAA was significant different between group 1-3 and group 2-3. Angle of second MT with horizontal plane of group 2 was smaller than control group and it was statistically significant. Other radiographic parameters have no statistical significance. CONCLUSION: Group 1 has long functional length of second MT and group 2 has small angle of second MT with horizontal plane.

Most distal radius fractures are currently being treated with anterior plating using anatomical precontoured locking compression plates via the anterior approach. However, it is difficult to fix the volar articular marginal fragment because these anatomical plates should be placed proximally to the watershed line. There were just a few methods of fixation for this fragment on medical literature. Herein, we introduced a tension band wiring technique for fixation of a volar articular marginal fragment in the distal radius.

Synovial chondromatosis is a rare lesion in the wrist, but some cases in the distal radioulnar joint have been reported and previous case reports emphasize joint calcifications, shown on preoperative plain radiographs. We report an extremely uncommon case of synovial chondromatosis in the pisotriquetral joint, in which radiographs and magnetic resonance imaging did not demonstrate apparent calcified bodies. In our case, for the accurate diagnosis and treatment, surgical exploration of the joint and synovectomy with removal of loose bodies was performed.

Triggering of the flexor tendon at the wrist is a rare phenomenon. The triggering can be caused by many different conditions, including anomalous muscle, thickened synovium, rheumatoid disease and tumors. We report the case of a 34-year-old man with triggering at the wrist and carpal tunnel syndrome caused by a fibroma of the flexor tendon.

OBJECTIVE: To find out the most useful method among three electrodiagnostic tests for carpal tunnel syndrome (CTS) in patients with diabetic peripheral polyneuropathy (PPN). METHOD: Eighty-three hands out of seventy-four patients who had diabetic PPN and tingling sensation in their hands were included in this study. They were divided into two groups: Group A, PPN with CTS; Group B, PPN only. Fifty-four hands with CTS in patients without diabetes were included as a control group (Group C). Another forty normal hands were also included as a healthy control group (Group D). Clinical and electrophysiologic information was gathered from those subjects. Sensitivity, specificity and receiver operating characteristic (ROC) curves of the three electrodiagnostic tests, namely, the difference between the median nerve latency to the second lumbrical muscle and the ulnar nerve latency to the second interosseous muscle (L-I difference), ratio of distoproximal latency in median sensory nerve (MW ratio), and difference of distoproximal latency in median sensory nerve (MW difference) to diagnose clinical CTS were obtained. RESULTS: The specificity of L-I difference as a diagnostic test for CTS was highest (87.0%). The area of ROC curve of L-I difference was also highest (0.949) among three different electrodiagnostic tests of CTS with diabetic PPN. CONCLUSION: We suggest that L-I difference as the most useful test with highest specificity for the diagnosis of CTS in the patients with diabetic PPN.

PURPOSE: The objective of this study was to evaluate clinical results of dual miniplate fixation for comminuted or periarticular fractures of the hand. MATERIALS AND METHODS: Twenty cases in 18 patients who had comminuted or periarticular fractures of metacarpal or phalangeal bones were treated with dual miniplate fixation from April, 2007 to May, 2009. The mean followed up period was 14.7 months. Our study included comminuted or periarticular fractures which were difficult to keep the fixation by pining or single plating. We evaluated radiologic bony union, angular or rotational deformity, extensor tendon irritaion and total arc of motion. RESULTS: Bony union was achieved successfully after primary dual miniplate fixationin in 12 cases. In 7 cases with a nonunion following previous operative fixation, bony union was obtained by dual miniplate fixation and bone grafting. In one case who had received primary dual plate fixation, nonunion occurred due to massive bone defect. Bony union was obtained by secondary dual plate fixation and bone grafting. Postoperative rotational deformity, angular deformity and irritation symptom were not observed in all cases. Functionally acceptable range of active motion was restored by way of early active motion. CONCLUSION: The dual miniplate fixation is one of the useful method for comminuted metacarpal or phalangeal fractures which cannot obtain firm fixation by other methods.

BACKGROUND/AIMS: Cyclic vomiting syndrome (CVS) is a disabling migraine variant manifesting as severe episodes of nausea and vomiting and often refractory to many therapies. Gastric electrical stimulation (GES), which can reduce nausea and vomiting in gastroparesis, may provide symptomatic relief for drug-refractory CVS. This study assessed the utility GES in reducing the symptoms of CVS and improving the quality of life. METHODS: A one-year, non-randomized, clinical study was conducted. Eleven consecutive patients with drug refractory, cyclic vomiting syndrome based on Rome III criteria and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN), underwent treatment with temporary GES (Temp GES) and permanent GES (Perm GES). Post-treatment follow up was done up to one year after permanent gastric electrical stimulation therapy. RESULTS: Total symptom score decreased by 68% and 40% after temporary and permanent GES therapies, respectively. Hospital admission events significantly decreased to 1.50 (± 1.00) events from 9.14 (± 7.21) annual admissions prior to treatment with permanent GES. Vomiting episodes fell by 83% post Temp GES and 69% after Perm GES treatments. Mucosal electrogram values also changed after temporary stimulation. CONCLUSIONS: In a small group of drug-refractory CVS patients, treatments with temporary and permanent GES significantly reduced the severity of gastrointestinal symptoms and frequency of hospital admissions.

PURPOSE: The purpose of this study was to evaluate clinical and radiological results after osteosynthesis of distal phalangeal nonunion with bone defect by using matchstick-shaped bone graft. MATERIALS AND METHODS: Fifteen distal phalangeal nonunions were treated with osteosynthesis using matchstick-shaped bone graft from September, 2009 to October, 2010. The mean age of patients was 36.1 years (range: 15 to 56 years). This study included 4 women and 10 men. The mean duration of follow-up was 16.8 months (range: 12 to 20 months). We evaluated radiographs, and measured postoperative visual analogue scale (VAS) score and pinch power. RESULTS: Union was achieved in all cases at a mean of postoperative 5.5 weeks (range: 4 to 6 weeks). The mean VAS score improved from 7.25 (range: 5 to 9) to 1.0 (range: 0 to 2) postoperatively. The mean postoperative pinch power was 7.75 lbs (range: 4 to 13 lbs) compared to opposite pinch power of 9.63 lbs (range: 5 to 15 lbs). There was no scar problem, pinch pain and other complication. CONCLUSION: Steosynthesis of distal phalageal nonunion with bone defect by using matchstick-shaped bone graft is technically feasible and simple in that it does not need volar incision and debridement. It is considered as an effective treatment option in distal phalangeal nonunion with bone defect.
