ber 1, 2015. Xiphodynia is a rare musculoskeletal disorder characterized by pain at the lower anterior chest or epigastric region. Treatment options include oral analgesics, local injection with analgesic or laser therapy. Yet, these often provide only short-term symptom relieve. A definite reduction in pain sensation might be achieved by performing a xiphoidectomy, though studies on its safety and efficacy are scarce. In the current single-centre study the outcomes of xiphoidectomy for xiphodynia are retrospectively assessed. All patients undergoing xiphoidectomy for xiphodynia between April 2013 and February 2020 at Zuyderland Medical Centre, Heerlen, the Netherlands, were included in this case series. Pain scores using the Numeric Rating Scale were assessed preoperatively and postoperatively and submitted to the Wilcoxon signed rank test. A clinically significant improvement was defined as a 2-point decrease in Numeric Rating Scale score. In addition, surgical outcomes, including complications and duration of surgery were extracted from the patient records. A total of 19 patients underwent xiphoidectomy for xiphodynia. The follow-up ranged from 1 to 83 months. Seventeen out of 19 patients showed a clinically relevant improvement in Numeric Rating Scale pain scores where the overall pain scores also revealed a statistically significant decrease from 8 (interquartile range, 7-8) to 0 (interquartile range, 0-0; P<0.001) after surgery. Median procedure time was 29 minutes (interquartile range, 24-38 minutes) and no postoperative complications occurred. Xiphoidectomy for xiphodynia is a safe and effective surgical procedure with good outcomes on pain relief. Though, future comparative studies are urged to elucidate its value among other treatment options.

This meta-analysis was conducted to compare the procedural and early outcomes of aortic valve replacement (AVR) using rapid deployment valve (RD group) versus sutureless valve (SU group). A literature search of 5 online databases was conducted. The primary outcomes were mean transvalvular pressure gradient (MPG) after AVR, the incidence of paravalvular leak (PVL) and the need for a permanent pacemaker implantation (PPI). The secondary outcomes included aortic cross-clamp (ACC) and cardiopulmonary bypass (CPB) times, early mortality and other postoperative complications, such as atrial fibrillation, bleeding reoperation and stroke. Eight articles were included, and all outcomes except MPG after AVR in matched valve sizes were extracted from 7 studies (RD group =842 patients and SU group =1,386 patients). The pooled analysis demonstrated a lower MPG in the RD group than in the SU group, with mean difference (MD) of 2.64 mmHg. The pooled risk ratios of any PVL and grade ≥2 (or moderate) PVL were not signifU valve. Early clinical outcomes showed no difference between RD and SU valve. Sternal fracture can result from multiple types of severe chest trauma and carries significant risk. Surgical fixation is an effective method for sternal fracture. The clinical data of patients with sternal fractures who presented to our hospital between August 2016 and July 2019 were collected. The 42 patients were divided into three groups, with 15 patients treated by internal fixation with NI-TI memory alloy embracing fixator, 10 patients receiving steel wire fixation, and 17 who received non-surgical treatment and who was designated as a control (conservative) group. Differences in clinical indices included the duration of surgery, blood loss, hospitalization, wound healing, hospitalization expenses, VAS scores, and patient satisfaction scores between the three groups was compared. The analysis of variance and t-test were used for quantitative variables, which were approximately normally distributed. Dichotomous data were compared used Pearson χ or Fisher's exact test, and a P value less than 0.05 was considered as statistically significant. All patients were cured, and there were no significant differences in general clinical features between the three groups (P>0.05). Thoracic deformity in the surgical groups was corrected anatomically and received better pain scores, while patients in the NI-TI memory alloy embracing fixator group showed advantages of bleeding and patient satisfaction (P<0.05). Operative treatment for a sternal fracture is safe, effective and can quickly restore the stability of the thorax. https://www.selleckchem.com/products/defactinib.html Memory alloy embracing fixator is markedly superior to other fixator materials.

The examination of lymph nodes (LNs) is critical for accurate node staging in patients with non-small cell lung cancer (NSCLC), but a consensus on the examinations of hilar and intrapulmonary (N1 station) LNs has not been reached. This study aimed to evaluate the role of LN dissection and pathological examination of N1 LN stations and their effects on survival in patients with stage IA-IIA NSCLC. Data from patients pathologically staged as IA-IIA who underwent radical surgery and confirmed as lacking LN metastases from January 2008 to March 2018 were retrospectively reviewed. The Kaplan-Meier method was used to determine the overall survival (OS) and disease-free survival (DFS). After propensity score matching (PSM), a Cox model was used to determine the prognostic factors. Of the 1,935 patients investigated, the median number of N1 stations examined was 3. Patients with at least 2 N1 stations examined had apparently better OS (P=0.002) and DFS (P=0.001). All patients were divided into patients with 0-1 N1 station examined and patients with 2-5 N1 stations examined. After PSM, the number of N1 stations examined was an independent prognostic factor for DFS (P=0.004). Patients with 2-5 N1 stations examined experienced prolonged DFS (P=0.010). Patients in group 12 experienced prolonged OS (P=0.021) and DFS (P=0.026). Patients in group 13 or 14 experienced prolonged OS (P=0.028). A larger extent of N1 station examination was associated with prolonged DFS in patients with stage IA-IIA NSCLC after lobectomy. The dissection and examination of at least 2 N1 stations included LNs from the lobar and segmental drainage fields.
