[Ab] Resumo:AIM: Neuropathic pain is a common clinical complication of nerve injury, and the effective treatment of neuropathic pain is still challenging. Ligustrazine is mainly used for the treatment of cardiovascular disease and its role in neuropathic pain is less investigated. The purpose of our study was to explore the effects of ligustrazine on neuropathic pain, as well as the underlying molecular mechanism. METHODS: Neuropathic pain was induced by chronic constriction injury (CCI) of the right sciatic nerve in Sprague-Dawley (SD) rats. After CCI, rats received ligustrazine, IL-6, or both. Mechanical withdrawal threshold (MWT) and paw withdrawal thermal latency (PWTL) were assessed on days 1, 3, 7, and 14 after surgery. Expression levels of tumor necrosis factor (TNF)-α, interleukin (IL)-ß, IL-2, and phosphorylation of Signal Transducer and Activator of Transcription (STAT) 3 were analyzed. RESULTS: Our results showed that both MWT and PWTL were significantly decreased by CCI on days 1, 3, 7 and 14 compared to sham group, however, ligustrazine reversed this effects. Additionally, the elevated levels of TNF-α, IL-1ß, and IL-2 in CCI spinal cord were inhibited by ligustrazine. Quantitative real-time (qRT-PCR) and Western blotting analysis showed that the test substance reduced the elevated expression of pSTAT3 in the spinal cord induced by CCI, and while IL-6 administration reversed the levels as well as the behavior responses. CONCLUSION: Our results suggest that ligustrazine could effectively attenuate neuropathic pain by inhibition of Janus Kinase (JAK)/STAT3 pathway in CCI rats.

[Ab] Resumo:INTRODUCTION: Nowadays the level of early and late complications after the operations for esophageal corrosive strictures such as esophago-organ anastomotic leak, development of infections, pneumonia, pleural empyema, mediastinitis, peritonitis, postoperative corrosive stricture development etc. remains rather high. Besides, postoperative mortality rate is high as well - 3.5-30 %. For that reason, an experimental model of esophageal stricture was suggested and ultrastructural mucosal changes in the stricture itself were studied to elaborate the unified pathogenic approach in treatment of esophageal stricture and improvement of its results. The aim of our work was to study the dynamics of ultrastructural changes both in normal esophageal walls and in third degree esophageal stricture Materials and Methods: The experiment was carried out on white male rats weighting 250-300 grams, to whom the third degree esophageal stricture model was created. After layer-by-layer incision of anterior abdominal wall abdominal portion of the esophagus was completely ligated (10 rats). In the control group (6 rats) anterior abdominal wall was opened with its subsequent layered closure. The animals were withdrawn from the experiment on the third day by ketamine overdose, and the samples were taken for ultrastructural study. RESULTS: Electron microscopic study of submicroscopic organization of basal, prickle, superficial epithelial cells in stratified non-squamous epithelium, smooth myocytes of muscle plate and contractile elements in esophageal muscular layer was carried out. Nuclear membrane, membranes of mitochondria, endoplasmic reticulum and cytoplasmic Golgi complex were found to be subjected to focal lysis. The third degree esophageal stricture caused destructive lesions in ultrastructural architectonics of stratified non-squamous epithelium cells, smooth myocytes of muscle plate and contractile elements in esophageal muscular layer of rats. CONCLUSION: Thus, catabolic processes leading to organelle disintegration develop in esophageal cells of rats with third degree stricture.

[Ab] Resumo:BACKGROUND AND PURPOSE: The purpose of this study was to investigate the frequency of symptomatic in-stent restenosis (ISR) and its contribution to nonprocedural symptomatic infarction in the SAMMPRIS trial (Stenting and Aggressive Medical Management for the Prevention of Recurrent Stroke in Intracranial Stenosis). METHODS: Patients without a periprocedural primary end point were followed up to determine the occurrence of any of the following events: ischemic stroke, cerebral infarct with temporary signs, or transient ischemic attack in the territory of the stented artery. Vascular imaging performed after these events was reviewed for ISR. Annual rates for symptomatic ISR were calculated using Kaplan-Meier estimates. RESULTS: Of 183 patients in the stenting group without a periprocedural primary end point, 27 (14.8%) had a symptomatic infarction (stroke or cerebral infarct with temporary signs) and 16 (8.7%) had transient ischemic attack alone in the territory during a median follow-up of 35.0 months. Of the 27 patients with infarctions, 17 (9.3%) had an ischemic stroke and 10 (5.5%) had a cerebral infarct with temporary signs alone. Adequate vascular imaging to evaluate ISR was available in 24 patients with infarctions (showing ISR in 16 [66.7%]) and in 10 patients with transient ischemic attack alone (showing ISR in 8 [80%]). The 1-, 2-, and 3-year rates (with 95% confidence limits) for symptomatic ISR in the SAMMPRIS stent cohort were 9.6% (6.1%-14.9%), 11.3% (7.5%-17.0%), and 14.0% (9.6%-20.2%), respectively. CONCLUSIONS: Symptomatic ISR occurred in at least 1 of 7 patients in SAMMPRIS by 3 years of follow-up and was likely responsible for the majority of nonprocedural cerebral infarctions.

[Ab] Resumo:Immunoglobulin (Ig)G4-associated cholangitis (IAC) is one of the common organ manifestations of IgG4-related systemic disease (ISD). IAC and autoimmune pancreatitis (AIP) may mimic sclerosing cholangitis, cholangiocarcinoma, or pancreatic carcinoma. Diagnosis is based on a combination of clinical, biochemical, radiological, and histological findings.To study the clinical presentation of and treatment strategy for IAC, we reviewed clinical, serologic, and imaging characteristics, as well as treatment response, in 39 patients with IAC. The majority of patients were men (82%). Clinical features on presentation included obstructive jaundice in 26 patients (67%) and abdominal pain in 20 (51%). Positive IgG4 immunostaining was seen in 27 patients. The median serum IgG4 level before treatment was 769.4 mg/dL (range, 309.1-1229.7 mg/dL). After the steroid therapy, the median serum IgG4 level in 23 patients was 247.0 mg/dL (range, 139.0-355.0 mg/dL). Cholangiograms were available in 36 (92%) patients. Stenosis of the lower part of the common bile duct was found in 26 of 39 patients. Stenosis was diffusely distributed in the intra- and extrahepatic bile ducts in 14 of 39 patients. Additionally, strictures of the bile duct were detected in the hilar hepatic lesions in 27 of 39 patients. AIP was the most frequent comorbidity (35/39 in this study) of IAC. Other affected organs included eyes (n = 6), salivary glands (sialadenitis, n = 10), lymph nodes (mediastinal and axillary, n = 3), kidneys (n = 2), and the retroperitoneum (retroperitoneal fibrosis, n = 2).Regarding treatment, 29 patients were treated with steroids, of whom one underwent pancreatoduodenectomy, and one underwent choledochojejunostomy. Eight patients were treated with biliary stents. The remaining 19 patients took prednisolone alone. Eight patients achieved spontaneous resolution. Four patients with suspected pancreatic cancer or cholangiocarcinoma underwent surgery, including 2 patients who also received postoperative steroids. All patients were regularly followed up for 9 to 36 months. Only 2 patients in the steroids treatment group relapsed to manifest obstructive jaundice and high serum IgG4 levels. These 2 patients were treated with steroids and biliary stents, resulting in complete remission.We also review the diagnostic and therapeutic management and discuss recent pathophysiological findings, which might aid in understanding the molecular mechanisms contributing to IAC and other manifestations of IgG4-related diseases (IgG4-RD). Biomarkers that are more accurate are needed to correctly diagnose IAC and prevent misdiagnoses and unnecessary therapeutic interventions.

[Ab] Resumo:OBJECTIVE: We describe our experience in transradial recanalization of the superficial femoral artery (SFA), and we provide a stepwise approach accounting for the patient's height and optimizing the yield of currently available devices. METHODS AND RESULTS: Fifteen patients with simple SFA disease, including 4 patients with total SFA occlusions <15 cm, were selected for stand-alone transradial recanalization. A 6F, 125-cm multipurpose guiding catheter was used to cannulate the limb of interest and support device delivery. The procedure was successful in all patients and consisted of balloon angioplasty (using 0.014″, 200-cm shaft monorail balloons) in all patients, and orbital atherectomy in 6 patients. We illustrate the steps and challenges of the transradial approach, namely the limited support in complex disease and the limited reach of current equipment. CONCLUSION: In patients with simple SFA disease, transradial recanalization appears feasible and safe but currently limited to balloon angioplasty ± orbital atherectomy. Proximal SFA stenting may be feasible in patients <160 cm in height.

[Ab] Resumo:BACKGROUND AND AIM: In living donor liver transplantation (LDLT), biliary complications continue to be the most frequent cause of morbidity and may contribute to mortality of recipients although there are advances in surgical techniques. This study will evaluate retrospectively the short-term and long-term management of biliary complications. METHODS: During the period from May 1999, to May 2004, 505 patients underwent 518 LDLT in the Department of Liver Transplantation and Immunology, Kyoto University Hospital, Japan. The data was collected and analyzed retrospectively. RESULTS: The recipients were 261 males (50.4%) and 257 females (49.6%). Biliary complications were reported in 202/518 patients (39.0%), included; biliary leakage in 79/518 (15.4%) patients, leakage followed by biloma in 13/518 (2.5%) patients, leakage followed by stricture in 9/518 (1.8%) patients, and biliary strictures in 101/518 (19.3%) patients. Proper management of the biliary complications resulted in a significant (p value 0.002) success rate of 96.5% compared to the failure rate which was 3.5%. CONCLUSION: Careful preoperative evaluation and the proper intraoperative techniques in biliary reconstruction decrease biliary complications. Early diagnosis and proper management of biliary complications can decrease their effect on both the patient and the graft survival over the long period of follow up.

[Ab] Resumo:RATIONALE: The typical intraoperative presentation of vertebral artery injury (VAI) usually involves profuse bleeding and requires immediate treatment. However, an occult VAI may occur intraoperatively and result in delayed life-threatening epidural pseudoaneurysm several days postoperatively. PATIENT CONCERNS: A 21-year-old man with compressive cervical myelopathy resulting from canal stenosis of skeletal fluorosis underwent decompression of C1 to C7 and instrumentation from C2 to C7. No impressive bleeding event occurred during the operation. On postoperative day 40, progressive quadriplegia developed. DIAGNOSES: Pseudoaneurysm of the VA was established by angiography. INTERVENTIONS: After occlusion of the right VA, the patient underwent hematoma clearing. OUTCOMES: Fortunately, the patient experienced significant recovery of neurologic function after the second surgery. LESSONS: From this case, we realize even in the absence of obvious signs of VAI during a cervical operation, postoperative evaluation should be mandatory for suspected bleeding events occurring at VAI-prone sites during surgery. Moreover, the bone morphological abnormality of skeletal fluorosis was determined to be the most important risk contributing to VAI in this case. The safety limits of bone removal should be determined preoperatively to avoid the effects of bone morphological abnormalities.

[Ab] Resumo:BACKGROUND: Approximately 20% of patients undergoing ankle brachial index testing for critical limb ischemia have noncompressible vessels because of tibial artery calcification. This represents a clinical challenge in determining tibial artery patency. We sought to identify the prevalence of tibial artery and pedal arch patency by angiography in these patients. METHODS AND RESULTS: One hundred twenty-five limbs (of 89 patients) with critical limb ischemia and ankle brachial index ≥1.4 who underwent lower extremity angiograms within 1 year were included. Reviewers of angiography were blinded to results of physiological testing. Tibial artery vessels were classified as completely occluded, significantly stenosed (≥50%), or patent (<50% stenosis). The sensitivity of toe brachial index and pulse volume recording to predict tibial artery disease was also determined. Of 125 limbs with noncompressible ankle brachial index, 72 (57.6%) anterior tibial and 80 (64%) posterior tibial arteries were occluded. Another 23 (18.4%) anterior tibial and 13 (10.4%) posterior tibial arteries had ≥50% stenosis. Pulse volume recording was moderate to severely dampened in 54 of 119 (45.4%) limbs. Toe brachial index <0.7 was found in 75 of 83 (90.4%) limbs. Moderate to severe pulse volume recording dampening was 43.6% sensitive, whereas toe brachial index <0.7 was 89.7% sensitive in diagnosing occluded or significantly stenotic tibial artery disease. The pedal arch was absent or incomplete in 86 of 103 (83.5%) limbs. CONCLUSIONS: Among patients with critical limb ischemia and noncompressible ankle brachial index results, the prevalence of occlusive tibial and pedal arch disease is very high. Toe brachial index <0.7 is more sensitive in diagnosing occluded and significantly stenotic tibial artery disease in these patients compared with ankle pulse volume recording.

[Ab] Resumo:Dipeptidyl peptidase-4 (DPP-4) inhibitors are hypoglycemic agents. DPP-4 inhibitor has cardioprotective effects after transverse aortic constriction (TAC), but role of DPP-4 on cardiac fibrosis after TAC is not well known. Our aim was to determine the effects of DPP-4 on cardiac fibrosis in murine TAC model. Wild-type mice and DPP-4 knockout mice were subjected to TAC. Wild-type mice were then treated with vehicle or DPP-4 inhibitor. DPP-4 activities in serum and heart tissue were significantly increased at 2 weeks after TAC, but they were significantly decreased by DPP-4 inhibitor treatment. The inhibition of DPP-4 did not affect left ventricular hypertrophy, but improved cardiac function and decreased myocardial and perivascular fibrosis after TAC. The inhibition of DPP-4 decreased the collagen type III/I ratio in myocardium. These results suggest that DPP-4 inhibition ameliorates the progression of heart failure after TAC by changing the quality and quantity of cardiac fibrosis.

[Ab] Resumo:OBJECTIVE: Evaluate the pathophysiology of contrast extravasation. METHODS: Two hundred fifty-five sialograms at the University of Iowa from 2008 to 2016 were reviewed. RESULTS: Twelve sialograms (4.7% of total) were identified with main ductal extravasation. In each case, ductal stenosis as a diagnosis was supported by clinical history and the finding of difficulty in advancing the cannula into the duct during sialography. In all but 1 case, extravasation occurred at the distal duct with no further imaging of the ductal system. Each of the 5 cases treated with sialendoscopy with or without gland resection confirmed stenosis. Ultrasound evaluation of 5 of the cases detected ductal dilation in 4 (80%). Six of 11 computed tomography scans done before the sialogram were interpreted as normal with indirect evidence for ductal stenosis (duct dilation) reported in only 1. All extravasations were associated with either stricture alone or stricture with stone (1 case). CONCLUSION: Radiocontrast extravasation from the main duct during sialography is highly associated with the presence of ductal stricture. In our experience, the inability to fill the ductal system with radiocontrast is a useful sialographic finding that correlated closely with anatomic abnormality rather than technical error. The frequent finding of extravasation of radiocontrast supports the use of water soluble contrast.
