BIA-ALCL diagnosis on CytoLyt fixed ThinPrep,cell block and immunohistochemistry

Breast implant associated anaplastic large cell lymphoma (BIA-ALCL) is an emergent rare T cell non-Hodgkin lymphoma arising in association with a breast implant, particularly textured ones. Recent guidelines list cytopathological examination as the first essential step for diagnosis, routinely followed by CD30 immunohistochemistry (IHC) and flow cytometry (FC) for a T cell clone. The majority of BIA-ALCL literature regarding cytopathological evaluation describes morphology based on various preparation methods limited to cytospins and smears with the exception of at least one case report detailing cytomorphological and IHC findings on ThinPrep. This case report details initial diagnosis of BIA-ALCL rendered with CytoLyt prepared ThinPrep and cell block, including the specific antibodies used for IHC. The ThinPrep slide showed numerous singly dispersed large, atypical cells with abundant cytoplasm containing irregular nuclei with dispersed chromatin and prominent nucleoli in a background of macrophages, inflammatory cells and granular debris. TIA-1 and CD30 along with other T-cell markers, including specific antibodies, remains immunoreactive in tissue collected in CytoLyt solution. Cell size reduction, artifactual lymphoid cell aggregation and prominent nucleoli in benign and reactive conditions are among other ThinPrep cellular alterations pathologists should bear in mind.     

Transient left bundle branch block after posture change to the prone position during general anesthesia: A case report

Rationale:The prone position is commonly used in spinal surgery. There have been many studies on hemodynamic changes in the prone position during general anesthesia. We report a rare case of transient left bundle branch block (LBBB) in a prone position.Patient concern:Electrocardiogram (ECG) of a 64-year-old man scheduled for spinal surgery showed normal sinus rhythm change to LBBB after posture change to the prone position.Diagnosis:Twelve lead ECG revealed LBBB. His coronary angio-computed tomography results showed right coronary artery with 30% to 40% stenosis and left circumflex artery with 40% to 50% stenosis. The patient was diagnosed with stable angina and second-degree atrioventricular block of Mobitz type II.Intervention:Nitroglycerin was administered intravenously during surgery. Adequate oxygen was supplied to the patient. After surgery, the patient was prescribed clopidogrel, statins, angiotensin II receptor blocker, and a permanent pacemaker was inserted.Outcome:Surgery was completed without complications. After surgery, the transient LBBB changed to a normal sinus rhythm. The patient did not complain of chest pain or dyspnea.Lesson:The prone position causes significant hemodynamic changes. A high risk of cardiovascular disease may cause ischemic heart disease and ECG changes. Therefore, careful management is necessary.     

超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌根治术中的应用

目的:研究超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌根治术中的应用价值。方法:选取90例择期进行腹腔镜结直肠癌根治术患者作为研究对象，随机分为观察组和对照组，各45例。对照组采用传统腰麻联合丙泊酚麻醉，观察组采用超声引导下腰方肌阻滞联合丙泊酚麻醉，比较两组患者术中（麻醉后5、15、30、60 min）收缩压（SBP）、舒张压（DBP）、心率（HR）和术后不同时间段的疼痛评分（VAS评分），以及加用镇痛药情况和肠道恢复排气时间和术后48 h内不良反应发生情况。结果:两组患者SBP、DBP、HR组间、不同时间点及交互差异均有统计学意义（P<0.05），且观察组麻醉后上述指标波动较对照组小（P<0.05）；麻醉前，两组患者皮质醇、肾上腺素水平无显著差异（P>0.05），麻醉后各时间点观察组患者上述指标水平均显著低于对照组（P<0.05）；两组患者VAS评分组间、不同时间点及交互差异均有统计学意义（P<0.05），且观察组术后各时间点VAS评分均显著低于对照组（P<0.05）；观察组不良反应发生率显著低于对照组（8.89% vs 24.44%, P<0.05）；观察组患者加用镇痛药的人数、剂量和肠道恢复排气时间均显著少于对照组（P<0.05）。结论:超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌手术中具有良好、稳定的麻醉效果，可有效缓解患者疼痛，减少术后不良反应发生。     

Patients' expectations,experience and acceptability of postoperative analgesia: a nested qualitative study within a randomised controlled trial comparing rectus sheath catheter and thoracic epidural analgesia

Adequate postoperative analgesia is a key element of enhanced recovery programmes. Thoracic epidural analgesia is associated with superior postoperative analgesia but can lead to complications. Rectus sheath catheter analgesia may provide an alternative. In a nested qualitative study (within a two-year randomised controlled trial) focussing on the acceptability, expectations and experiences of receiving the interventions, participants (n = 20) were interviewed 4 weeks post-intervention using a grounded theory approach. Constant comparative analysis, with patient and public involvement, enabled emerging findings to be pursued through subsequent data collection. We found no notable differences regarding postoperative acceptability or the experience of pain management. Pre-operatively, however, thoracic epidural analgesia was a source of anticipatory fear and anxiety. Both interventions resulted in some experienced adverse events (proportionately more with thoracic epidural analgesia). Participants had negative experiences of the insertion of thoracic epidural analgesia; others receiving the rectus sheath catheter lacked confidence in staff members' ability to manage the local anaesthetic infusion pump. The anticipation of the technique of thoracic epidural analgesia, and concerns about its impact on mobility, represented an additional, unpleasant experience for patients already managing an illness experience, anticipating a life-changing operation and dealing with concerns about the future. The anticipation of rectus sheath catheter analgesia was not associated with such anxieties. Patients' experiences start far earlier than the experience of the intervention itself through anticipatory anxieties and fears about receiving a technique and its potential implications. Complex pain packages can take on greater meaning than their actual efficacy in relieving postoperative pain. Future research into patient acceptability and experience should not focus solely on efficacy of pain relief but should include anticipatory fears, anxieties and experiences.     

A prospective study of multimodal cocktail intercostal injection for chest pain relief after costal cartilage harvest for rhinoplasty

Our aim was to evaluate the efficacy and safety of multimodal cocktail intercostal injection for the relief of chest pain after costal cartilage harvest for rhinoplasty. Consecutive patients who underwent costal cartilage harvest during rhinoplasty were prospectively assigned as per patient preference to group A (injection containing ropivacaine, parecoxib sodium, epinephrine, and compound betamethasone), group B (intercostal nerve block (ICNB)), or group C (ICNB plus patient-controlled analgesia (PCA)). The outcomes were visual analogue scale (VAS) scores for chest pain after costal cartilage harvest, rescue analgesia, complications, and cost during the first two days. Of the 66 patients assessed, 63 (29 patients in group A, 13 in group B, and 21 in group C) were eligible and included. The VAS scores in group A were significantly lower than those in groups B and C (all p<0.001). Group A had a significantly lower rate of rescue analgesia due to a VAS score of more than 4 (3.45%, 1/29) compared with group B (46.15%, 6/13; p=0.001) and group C (28.57%, 6/21; p=0.012). Complications were observed only in group C (nausea/vomiting 28.57%; dizziness/headache 23.81%), which differed significantly from group A (p=0.002 and 0.006, respectively). The mean cost for group A (US $15 (0)) was significantly lower than it was for group C (US $113.1 (4.4), p<0.05), but higher than it was for group B (US $5.97 (0), p= -). Multimodal cocktail intercostal injection may be superior for chest pain relief after costal cartilage harvest for rhinoplasty compared with ICNB with or without PCA. Further study is warranted.
