Anterior Interosseous Nerve Palsy After Shoulder Arthroscopy Treated With Surgical Decompression: A Case Series and Systematic Review of the Literature

Background: Anterior interosseous nerve (AIN) palsy is a very uncommon cause of upper extremity pain and weakness that comprises less than 1% of all upper extremity nerve palsies. Rarely reported but also mentioned in the literature is AIN palsy after shoulder arthroscopy. Methods: A systematic review of the literature to date using PubMed was conducted to identify patients who suffered AIN palsy after shoulder arthroscopy procedures. Articles included met the following criteria: (1) published in English; (2) primary presentation of the data; (3) patients had undergone shoulder arthroscopy before developing symptoms of AIN palsy; and (4) diagnosis was confirmed with clinical symptoms of AIN palsy. Measured outcomes included patient demographics, specific shoulder procedure, anesthesia procedure, intra-operative patient positioning, intra-operative compressive dressing, intra-operative traction, surgical versus conservative treatment, abnormal findings during decompression procedure, proposed mechanism of injury, and follow-up. Results: The search yielded 6 articles, of which 4 (13 cases) met inclusion criteria. An additional 2 cases were included in this report totaling 15 cases. The average patient age was 49 years (range: 31-64) with 73% males. At average follow-up of 24 months, 67% of patients experienced complete resolution of symptoms—more than half of which underwent surgical decompression. Patients who failed to progress experienced weakness of the flexor digitorum profundus and flexor pollicis longus muscles. Conclusions: Proposed injury mechanisms for AIN palsy after shoulder arthroscopy range from mechanical trauma, compressive hematoma, and direct anesthetic neurotoxicity. Management should be directed by clinical symptoms, imaging, and patient factors with majority of patients expected to have excellent clinical outcomes.     

不同尿钙水平的Gitelman综合征患者临床特点比较

目的观察不同尿钙水平Gitelman综合征(GS)患者的临床特点,探讨尿钙在GS疾病临床分型中的价值。方法收集2016—2018年来自中国国家罕见病注册系统(NRSC)、在北京协和医院行SLC12A3基因检测诊断为GS患者的临床资料,分析其尿钙特点,比较不同尿钙水平患者的临床和实验室检查指标。氢氯噻嗪试验按照标准操作流程进行,测定患者基线和用药后3 h内氯离子排泄分数改变量的最大值(ΔFECl)。结果共有83例GS患者被纳入研究,其中低尿钙患者53例(63.86%)。低尿钙组尿钙/肌酐比明显低于非低尿钙组[(0.085±0.058)mmol/mmol比(0.471±0.284)mmol/mmol,t=7.349,P<0.001]。两组患者在年龄、性别、估算肾小球滤过率、血压、血尿电解质水平、代谢性碱中毒方面差异均无统计学意义。低尿钙组患者乏力(χ2=4.595,P=0.032)及多尿(χ2=5.778,P=0.016)发生比例低于非低尿钙组,两组患者在其他临床症状方面差异无统计学意义。低尿钙和非低尿钙组各有16例患者行氢氯噻嗪试验,中位ΔFECl结果分别为0.539%(0.430%,1.283%)和0.829%(0.119%,1.298%),均提示对氢氯噻嗪无反应,组间差异无统计学意义(U=130.000,P=0.956)。结论GS患者中低尿钙比例为63.86%,尿钙水平与疾病临床表型、NCC功能损伤严重程度之间均无明确相关性。     

Fibrinogen-thrombin collagen patch reinforcement of highrisk colonic anastomoses in rats

AIM To evaluate the effectiveness of human fibrinogenthrombin collagen patch(TachoSil~?) in the reinforcement of high-risk colon anastomoses.METHODS A quasi-experimental study was conducted in Wistar rats(n = 56) that all underwent high-risk anastomoses(anastomosis with only two sutures) after colectomies. The rats were divided into two randomized groups: Control group(24 rats) and treatment group(24 rats). In the treatment group, high-risk anastomosis was reinforced with TachoSil~? (a piece of Tacho Sil? was applied over this high-risk anastomosis, covering the gap). Leak incidence, overall survival, intra-abdominal adhesions, and histologic healing of anastomoses were analyzed. Survivors were divided into two subgroups and euthanized at 15 and 30 d after intervention in order to analyze the adhesions and histologic changes. RESULTS Overall survival was 71.4% and 57.14% in the TachoSil~? group and control group, respectively(P = 0.29); four rats died from other causes and six rats in the treatment group and 10 in the control group experienced colonic leakage(P 0.05). The intra-abdominal adhesion score was similar in both groups, with no differences between subgroups. We found non-significant differences in the healing process according to the histologic score used in both groups(P = 0.066).CONCLUSION In our study, the use of TachoSil~? was associated with a non-statistically significant reduction in the rate of leakage in high-risk anastomoses. TachoSil~? has been shown to be a safe product because it does not affect the histologic healing process or increase intra-abdominal adhesions.

Fluorescence in the Sclera,Nails, and Teeth Secondary to Favipiravir Use for COVID-19 Infections

Favipiravir, an antiviral agent originally used for influenza infections, has become popular due to its beneficial signals in coronavirus disease. It is currently used in some countries within COVID-19 treatment protocols. This is an initial report of favipiravir-related fluorescence observed in three healthcare providers working in the same ward in our hospital. All three individuals had been diagnosed with COVID-19 two months earlier and were treated with favipiravir. None of the three individuals received hydroxychloroquine or tetracyclines. Wood’s light examination led to an incidental discovery of favipiravir-induced fluorescence involving the sclera, nails, and teeth. In all patients, white linear, square, and band-like specks of fluorescence were noticed on the sclera of both eyes, some teeth, and the proximal part of all fingernails and toenails. Exposure of the eyes to the Wood’s light was for a brief duration of 3 to 5 seconds during examination and photodocumentation. Favipiravir might cause bright white fluorescence of nails, sclera, and teeth, detectable by Wood’s light even two months after its cessation.     

Safety and tolerability of single intravenous doses of sugammadex administered simultaneously with rocuronium or vecuronium in healthy volunteers

BACKGROUND: Sugammadex rapidly reverses rocuronium- and vecuronium-induced neuromuscular block. To investigate the effect of combination of sugammadex and rocuronium or vecuronium on QT interval, it would be preferable to avoid the interference of anaesthesia. Therefore, this pilot study was performed to investigate the safety, tolerability, and plasma pharmacokinetics of single i.v. doses of sugammadex administered simultaneously with rocuronium or vecuronium to anaesthetized and non-anaesthetized healthy volunteers. METHODS: In this phase I study, 12 subjects were anaesthetized with propofol/remifentanil and received sugammadex 16, 20, or 32 mg kg(-1) combined with rocuronium 1.2 mg kg(-1) or vecuronium 0.1 mg kg(-1); four subjects were not anaesthetized and received sugammadex 32 mg kg(-1) with rocuronium 1.2 mg kg(-1) or vecuronium 0.1 mg kg(-1) (n=2 per treatment). Neuromuscular function was assessed by TOF-Watch SX monitoring in anaesthetized subjects and by clinical tests in non-anaesthetized volunteers. Sugammadex, rocuronium, and vecuronium plasma concentrations were measured at several time points. RESULTS: No serious adverse events (AEs) were reported. Fourteen subjects reported 23 AEs after study drug administration. Episodes of mild headache, tiredness, cold feeling (application site), dry mouth, oral discomfort, nausea, increased aspartate aminotransferase and gamma-glutamyltransferase levels, and moderate injection site irritation were considered as possibly related to the study drug. The ECG and vital signs showed no clinically relevant changes. Rocuronium/vecuronium plasma concentrations declined faster than those of sugammadex. CONCLUSIONS: Single-dose administration of sugammadex 16, 20, or 32 mg kg(-1) in combination with rocuronium 1.2 mg kg(-1) or vecuronium 0.1 mg kg(-1) was well tolerated with no clinical evidence of residual neuromuscular block, confirming that these combinations can safely be administered simultaneously to non-anaesthetized subjects. Rocuronium and vecuronium plasma concentrations decreased faster than those of sugammadex, reducing the theoretical risk of neuromuscular block developing over time.

血浆凝血因子VIII水平与IgA肾病患者临床病理改变及预后的关系

目的探讨血浆凝血因子VIII(factor VIII,FVIII)水平与IgA肾病(IgAN)患者临床参数及预后的关系。方法收集2016年1月至2016年12月中南大学湘雅二医院确诊的IgAN患者的临床资料。按照时间依赖的受试者工作特征曲线(ROC)得出的血浆FVIII预测IgAN预后的临界值,将患者分为高FVIII组(FVIII>140.50%)和低FVIII组(FVIII≤140.50%),比较两组患者肾活检时基线临床参数的差异。以估算肾小球滤过率(eGFR)下降≥30%或进入终末期肾脏病(ESRD)为终点事件,采用Kaplan-Meier生存曲线及Cox回归方程法分析血浆FVIII水平对IgAN患者预后的影响。结果共93例IgAN患者纳入本研究,中位随访时间为35.15(33.77,36.76)个月,12例(12.90%)患者发生终点事件。高FVIII组患者年龄、血肌酐、尿素氮、血三酰甘油、血总胆固醇、血浆纤维蛋白原、D-二聚体、24 h尿蛋白量、蛋白C、蛋白S和eGFR下降速率高于低FVIII组(均P<0.05);eGFR、血白蛋白、中位随访时间低于低FVIII组(均P<0.05)。Kaplan-Meier生存分析结果显示,与低FVIII组比较,高FVIII组患者肾脏累积生存率降低(χ2=5.635,P=0.018)。在校正收缩压、eGFR、尿蛋白、肾小管萎缩/间质纤维化程度等因素后,多因素Cox回归分析结果显示,高血浆FVIII水平是IgAN患者肾脏预后不良的独立危险因素(HR=4.147,95%CI 1.055~16.308,P=0.042)。结论血浆FVIII水平与IgAN患者临床指标及预后相关,高血浆FVIII水平是IgAN患者肾脏预后不良的独立危险因素。     

Factors Associated With Reoperation After Silicone Proximal Interphalangeal Joint Arthroplasty

Background: Silicone proximal interphalangeal (PIP) joint arthroplasty has a high revision rate. It has been suggested that persistent ulnar deviation and joint instability influence the durability of PIP silicone arthroplasties. The goal of this study was to evaluate what factors are associated with reoperation after silicone PIP arthroplasty. Methods: We retrospectively evaluated all adult patients who underwent PIP silicone arthroplasty between 2002 and 2016 at one institutional system for inflammatory-, posttraumatic-, and primary degenerative arthritis. After manual chart review, we included 91 patients who underwent 114 arthroplasties. Fingers operated included 14 index, 41 middle, 38 ring, and 21 small fingers. Results: The overall reoperation rate was 14% (n = 16). Non-Caucasian race (P = .040), smoking (P = .022) and PIP silicone arthroplasty for post-traumatic osteoarthritis (P = .021) were associated with reoperation. The 1-, 5- and 10-year implant survival rates were 87%, 85%, and 85%, respectively. Conclusion: Caution should be exercised when considering PIP silicone arthroplasty of the index finger or in patients with post-traumatic osteoarthritis. It may be worthwhile addressing smoking behavior before pursuing silicone PIP arthroplasty.
