We report the clinical results and problems of combined administration of rifampicin, ethambutol, and clarithromycin (REC) for the treatment of Mycobacterium avium complex (MAC) infection of the hand (hand MAC). Participants included 7 patients with hand MAC. After resection of the infected lesion, REC was prescribed for 12 months. ⋯ REC provided relatively good clinical results as a treatment for hand MAC. However, recurrences were observed even after the completion of REC and the use of an alternative drug. Optimal duration of REC and appropriate alternative drugs need to be identified in the future.

Anemia is a common complication in patients with renal failure. While erythropoietin is commonly used to treat anemia, some patients exhibit a poor response to erythropoietin. Since store-operated calcium channel (SOC) signaling is one of the erythropoietin activated pathways, we aimed to investigate the association between the genetic polymorphisms of SOC signaling pathway and erythropoietin resistance in patients with renal failure. ⋯ Functional annotation of expression quantitative trait loci revealed that the AA genotype of rs1561876 in STIM1 has a relatively lower expression of ribonucleotide reductase catalytic subunit M1 in skeletal muscle, while the CC genotype of rs6486795 in ORAI1 has a relatively higher expression of ORAI1 in the whole blood and thyroid. Overall, we demonstrate a significant association between erythropoietin resistance and genetic polymorphisms of STIM1 and ORAI1. Annotation prediction revealed the importance of SOC-mediated calcium signaling for erythropoietin resistance.

Randomized Controlled Trial
Efficacy of modified pressure cuff for thrombolytic treatment on lower extremity deep venous thrombosis.
To compare the effectiveness and patient comfort between two methods that block superficial venous blood flow during the thrombolytic treatment of lower extremity deep venous thrombosis (DVT) to provide evidence that informs clinical choice. One hundred twenty patients with lower extremity DVT were randomly divided into sphygmomanometer (group A, n = 40), tourniquet (group B, n = 40), and control group (no blocking, n = 40). All the patients were treated with a daily dosage of urokinase using a dial sphygmomanometer cuff and tourniquet to block lower extremity superficial vein blood flow. ⋯ The leg pain scores of group A were lower than those of group B and control group. The postoperative comfort ratio of group A was higher than that of group B, and the proportion of severe discomfort in group A was lower than that in group B. Compared with the tourniquet, using a dial sphygmomanometer cuff to block lower extremity superficial vein blood flow achieved a better thrombolytic effect on DVT and provided higher patient comfort during treatment.

Case Reports
Lumbosacral plexopathy due to pelvic hematoma after extracorporeal membrane oxygenation: A case report.
Peripheral nerve injury related to vascular complications associated with extracorporeal membrane oxygenation (ECMO) is perhaps underappreciated. Compared to the well-described central nervous system complications of ECMO, brachial plexopathy and lumbosacral plexopathy have rarely been reported. We report this case to heighten awareness of lumbosacral plexus injury due to pelvic hematoma formation after ECMO. ⋯ Neurological deficits occurring during the course of administration of ECMO require accurate localization. Neurology consultation and/or EMG/NCS may be useful if localization is not clear. Lesions localizing to the lumbosacral plexus should prompt radiographic evaluation with computed tomography of the abdomen and pelvis. Hemostasis of a retroperitoneal hematoma may be achieved with embolization. However, if neurological deficits do not improve, surgical consultation for hematoma evacuation may be warranted.

Programmed death protein 1 (PD-1) pathway is one of the most critical mechanisms in tumor biology of hepatocellular carcinoma (HCC). The study aimed to assess the prognostic influence of pretransplant serum soluble PD-1 (sPD-1) in patients undergoing liver transplantation for treatment of HCC. Data from 229 patients with HCC who underwent living donor liver transplantation between January 2010 and December 2015 were retrospectively evaluated. ⋯ Multivariate analysis revealed that only Milan criteria was an independent prognostic for OS and DFS, but pretransplant sPD1 with a cut-off of 300 μg/mL did not become a prognostic factor. The results of this study demonstrate that pretransplant serum sPD-1 did not show significant influences on post-transplant outcomes in patients with HCC. Further large-scale, multicenter studies are necessary to clarify the role of serum sPD-1 in liver transplantation recipients.
