RESUMO

BACKGROUND: Different combinations of excision and adjuvant therapies have been applied to improve outcomes for earlobe keloids, though evidence in this field is still lacking. OBJECTIVES: This study sought to systematically investigate efficacy and safety of these treatments. METHODS: We conducted a systematic search on PubMed, Embase, Web of Science, and Cochrane Library to find all relevant studies. Meta-analysis of recurrence rates (RRs) and adverse event rates with 95% confidence intervals, and individual participants data (IPD) were calculated for each intervention when possible. Otherwise, narrative syntheses were performed. RESULTS: A total of 85 articles, covering 23 treatments for earlobe keloids, were included, indicating a preference for multiple combination therapy. The estimated RRs for 6 interventions (i.e., excision monotherapy, combinations of excision with imiquimod, pressure therapy, radiotherapy, steroids, and steroids with pressure therapy) appeared to be comparable. Electron radiotherapy was found to have potential advantages over X-ray treatment, contributing to the observed heterogeneity. Further meta-analysis using IPD revealed that both combination therapies of excision plus steroid therapy (p=0.003) and excision plus radiotherapy (p=0.003) yielded better recurrence-free survival compared to excision alone. The median recurrence-free interval for combination therapy was 10 months. Adverse event rates were similar among different intervention groups. CONCLUSIONS: This study suggests that combining excision with radiotherapy or perioperative steroid therapy has the potential to improve prognosis of earlobe keloids without increasing the risk of adverse events. Overall evaluation of patients' conditions and further studies with sufficient follow-up are warranted for clinical practice. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

RESUMO

Thrombus formation on a well-conserved bicuspid aortic valve is rare. We encountered a patient with organized thrombus formation on a native bicuspid aortic valve without calcification or stenosis, which was found occasionally during an elective operation for ascending aorta replacement surgery. The location of the thrombus was just at the orifice of left coronary artery, which produced the atherosclerosis-like symptoms such like exertional chest tightness and dyspnea. And these are no apparent predisposing causes of thrombosis could be ascertained postoperatively. The patient is in excellent condition 6 months after the operation. The lesson we learned from our case is that when the patient's symptom can't correspond with his or her diagnosis, we should ask more questions, evaluate the patient thoroughly and make the differential diagnosis as possible as we can. And the surgery can be performed aggressively when patient's symptoms cannot be figured out by physical examination, not only for pathologic confirmation but also for the prevention of life-threatening complications that can caused by either condition.

RESUMO

Cardiac tumors are rare. They were found in only 0.001%-0.300% of cases in a relatively recently reported autopsy series. Among cardiac tumors, primary hemangioma accounted for approximately 2.8% of all primary resected tumors, indicating this is a particularly rare benign neoplasm. We present a patient with a 5×3×2 cm cavernous hemangioma, arising from the right atrial roof and occupying the atrial septum and inseparable from the aortic root. We successfully accomplished a complete surgical resection of a cardiac cavernous hemangioma and reconstructed the cardiac atrium by a bovine pericardial patch.

RESUMO

BACKGROUND: Atrial fibrillation is the most common and long-lasting cardiac arrhythmia, and profoundly effects the daily lives of patients. The pathogenesis and persistence of atrial fibrillation is closely related to the cardiac fibroblast and its myofibroblast differentiation as increased collagen synthesis and migration capability. Thus better understanding of myofibroblast differentiation is essential for the prevention and treatment of atrial fibrillation. METHODS: Cardiac fibroblasts were isolated from neonatal rats and its actin structure was analyzed by immunofluorescence staining. Myofibroblast differentiation was induced by Angiotensin II (Ang II) and ROCK signaling related proteins were determined by western blot. Fasudil and Ricolinostat were employed to abrogate ROCK signaling and their effects on myofibroblast differentiation were assessed by IF microscopy and Celigo Image Cytometry. RESULTS: Stress actin fibers similar to actin filaments in myofibroblast differentiation are regulated by ROCK signaling, and our results also suggested Guanine nucleotide exchange factor-H1 (GEF-H1) phosphorylation could be induced by Ang II. In addition, Fasudil could down-regulate RhoA, GEF-H1, and phosphorylated GEF-H1 to inhibit ROCK signaling and further reduce Col I expression and the myofibroblast proportion. CONCLUSIONS: An individual phase characterized by actin-granule formation was identified in cardiac myofibroblast differentiation. In the meanwhile, myofibroblast differentiation and its F-actin assembly could be detained in this phase by Fasudil abrogating the ROCK signaling pathway.

RESUMO

BACKGROUND: Many patients develop chronic postsurgical pain (CPSP) after cardiac surgery, which interferes with their sleep, mood, and quality of life. Studies have suggested that propofol improves postoperative analgesia compared with volatile anesthetics, but its preventive effect on CPSP following cardiac surgery is still unknown. This study compares the incidence of CPSP following cardiac surgery for those receiving volatile anesthesia and those receiving propofol-based total intravenous anesthesia (TIVA) using criteria recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT). METHODS/DESIGN: This is a prospective randomized controlled trial. In total, 500 adults undergoing cardiac surgery will be randomly allocated to the volatile or the TIVA group. The volatile group will receive sevoflurane or desflurane during surgery as general anesthesia. The TIVA group will receive propofol-based intravenous agents and no volatile agents during surgery. The primary outcomes will be the frequency of CPSP at 3 months, 6 months, and 1 year after surgery. In this case, CPSP is sternal or thoracic pain. It is defined as either (1) numerical rating scale (NRS) > 0 or (2) meeting all six IMMPACT criteria for CPSP. The IMMPACT criteria are validated pain instruments. DISCUSSION: To our knowledge, this is the first prospective randomized controlled trial to investigate the prevention of CPSP following cardiac surgery for patients receiving volatile anesthesia compared to those receiving propofol-based TIVA using validated pain instruments in accordance with the IMMPACT recommendations. This study will provide important information on which of these two anesthetic regimens is better for preventing CPSP after cardiac surgery. TRIAL REGISTRATION: Chictr.org.cn, ChiCTR1900020747.

RESUMO

INTRODUCTION: Many studies have found that volatile anesthetics are associated with improved clinical outcomes for adults undergoing coronary artery bypass grafting. However, the effect of volatile anesthetics for adults after heart valve surgery has been unclear. So we conducted a meta-analysis of randomized controlled trials (RCTs) to explore whether the choice of an anesthetic regimen might influence patients' outcomes after valve surgery. EVIDENCE ACQUISITION: PubMed, Embase, and Cochrane Library were searched from inception to June 2018. We included eligible research comparing inhalation anesthesia with total intravenous anesthesia (TIVA) in adult patients undergoing valve surgery. The major endpoints involved mortality, postoperative arrhythmia, acute kidney injury, pulmonary complications, neurological events, myocardial infarction, reoperation for bleeding. The postoperative peak troponin release, hospital stay, Intensive Care Unit (ICU) stay and ventilation time were also analyzed. EVIDENCE SYNTHESIS: After screening through 243 potentially relevant articles, we included 13 RCTs with 962 patients. The inhalation anesthesia group revealed comparable mortality (inhalation group 12/249 [4.8%] vs. TIVA group 13/247 [5.3%], RR=0.97; 95% CI: 0.45 to 2.09; P=0.93; P for heterogeneity=0.66, I2=0%) and other postoperative complications with no heterogeneity. The postoperative peak troponin release, hospital/ICU stay and ventilation time were comparable between two groups with considerable heterogeneity. CONCLUSIONS: Among patients undergoing heart valve surgery, the use of inhalation anesthesia compared with TIVA failed to demonstrate superiority for survival and major postoperative complications, and the evidence was insufficient to draw firm conclusions due to the limited sample size. A determination of equivalence or superiority between these two anesthetic regimens requires further researches.
