PURPOSE: This case is conducted to assess the short term safety and efficacy of intravitreal bevacizumab injection in patient with early stage of the neovascular glaucoma (NVG) without peripheral anterior synechiae. CASE SUMMARY: A 66 year old patient with a history of proliferative diabetic retinopathy presented with neovascularization of the iris and the angle and high intraocular pressure of 30 mmHg. The patient received a single injection of bevacizumab (1.25 mg /0.05 mg) intravitreally. The visual acuity (VA), intraocular pressure (IOP), regression of the iris and the angle neovascularization were measured up to the twenty ninth week after injection. Regression of the iris and angle neovascularization were confirmed from the second week after injection. The visual acuity had continued stable and the IOP had been controlled from 30 mmHg to 20 mmHg from fifth week without the need for topical antiglaucoma medications until the twenty ninth week. CONCLUSIONS: Bevacizumab may be an effective medication for the treatment of neovascular glaucoma. Bevacizumab seems to be a useful adjunct or an advantageous treatment option to panretinal photocoagulation in the treatment of neovascular glaucoma.

Purpose: We intend to evaluate the efficacy of salvage treatments for relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL) through meta-analysis. Materials and Methods: R/R DLBCL trials were divided into two groups based on eligibility for autologous stem-cell transplantation (ASCT), and meta-analysis of each group was performed. Random effects models were used to estimate the 1-year progression-free survival (PFS) rate, and chimeric antigen receptor (CAR) T-cell therapy was used as reference treatment. Results: Twenty-six ASCT-eligible cohorts from 17 studies comprising 2,924 patients and 59 ASCT-ineligible cohorts from 53 studies comprising 3,617 patients were included in the pooled analysis. In the ASCT-eligible group, the pooled 1-year PFS rate was 0.40 (95% confidence interval [CI], 0.15 to 0.65) for the CAR T-cell group and 0.34 (95% CI, 0.30 to 0.37) for the group with chemotherapy followed by ASCT intention. The two treatments were not significantly different in meta-regression analysis. In the ASCT-ineligible group, the pooled 1-year PFS was 0.40 (95% CI, 0.35 to 0.46) for CAR T-cell, and the highest primary outcome was 0.47 (95% CI, 0.37 to 0.57) for the tafasitamab group. CAR T-cell therapy showed significantly better outcomes than chemotherapy and therapies based on ibrutinib, lenalidomide, and selinexor. However, loncastuximab, polatuzumab plus bendamustine and rituximab, and the tafasitamab group showed no different efficacy than CAR T-cell therapy after adjusting for median number of previous lines of treatment. Conclusion Although several regimens were crudely grouped for classification, CAR T-cell therapy did not outperform chemotherapy followed by ASCT in the second-line setting or several recently developed agents in the ASCT-ineligible setting.

Adenoid cystic carcinoma formerly called cylindroma is rare tracheal tumor. Characteristics of adenoid cystic carcinoma are infiltrative nature with local recurrence tendency and long natural course of the disease. Adenoid cystic carcinomas develop most commonly in the trachea. Primary resection and end-to-end anastomosis of the involved airway are treatment of choice. And postoperative radiation therapy might be useful, particularly when the surgical margins are not ample. We report two cases of adenoid cystic carcinoma of trachea diagnosed by flow-volume curve.

Lithium is the drug of choice for treating bipolar affective disorders. However, it has a narrow therapeutic index and acute and chronic toxicity can occur in patients with chronic ingestion. Chronic toxicity commonly presents as nephrogenic diabetes insipidus or thyroid dysfunction. Neurologic symptoms such as apathy, hyperreflexia, or clonus can also occur in acute toxicity. However, it rarely causes peripheral neuropathy. We experienced a case of lithium-induced peripheral polyneuropathy who had already nephrogenic diabetes insipidus and chronic kidney disease during 25 years of lithium ingestion due to bipolar disorder.

With its high efficiency for site-specific genome editing and easy manipulation, the clustered regularly interspaced short palindromic repeats (CRISPR)/ CRISPR associated protein 9 (CAS9) system has become the most widely used gene editing technology in biomedical research. In addition, significant progress has been made for the clinical development of CRISPR/CAS9 based gene therapies of human diseases, several of which are entering clinical trials. Here we report that CAS9 protein can function as a genome mutator independent of any exogenous guide RNA (gRNA) in human cells, promoting genomic DNA double-stranded break (DSB) damage and genomic instability. CAS9 interacts with the KU86 subunit of the DNA-dependent protein kinase (DNA-PK) complex and disrupts the interaction between KU86 and its kinase subunit, leading to defective DNA-PK-dependent repair of DNA DSB damage via non-homologous end-joining (NHEJ) pathway. XCAS9 is a CAS9 variant with potentially higher fidelity and broader compatibility, and dCAS9 is a CAS9 variant without nuclease activity. We show that XCAS9 and dCAS9 also interact with KU86 and disrupt DNA DSB repair. Considering the critical roles of DNA-PK in maintaining genomic stability and the pleiotropic impact of DNA DSB damage responses on cellular proliferation and survival, our findings caution the interpretation of data involving CRISPR/CAS9-based gene editing and raise serious safety concerns of CRISPR/CAS9 system in clinical application.
