Cervical nerve root injury is one of the complications of traumatic cervical spine fracture. Although one of the most effective treatments to reduce inflammation in nerve root injuries is the use of corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids and NSAIDs can inhibit bone healing. So, when nerve injury accompanies bone fractures, corticosteroids and NSAIDs have limitations as therapeutic agents. However, polydeoxyribonucleotide (PDRN) may be useful in the treatment of neuropathy or musculoskeletal pain patients with contraindication of the use of corticosteroids because of its anti-inflammatory effect, as revealed in previous studies. To the best of our knowledge, there has been no report of treatment of traumatic nerve root injury due to an articular process fracture with an ultrasound-guided cervical nerve root block (NRB) using PDRN. ⋯ Although it is impossible to draw a conclusion from a single case report, we suggest the ultrasound-guided NRB using PDRN could be a useful treatment for alleviating motor weakness and neuropathic pain caused by traumatic spinal nerve root injury in situations where corticosteroids cannot be used.

Case Reports
Case report: an unusual case of Brugada syndrome combined with a ventricular septal defect: A case report.
Brugada syndrome (BrS) is a cardiac ion channel disease that is caused by an autosomal dominant genetic abnormality. A ventricular septal defect is a common congenital heart disease, in which genetic defects play a significant role. ⋯ To our knowledge, this is the first genetically proven case of BrS combined with a ventricular septal defect.

Cytochrome P4502E1 (CYP2E1) gene genetic polymorphisms vary markedly in frequency among different ethnic and racial groups. We studied the genotype distributions and allele frequencies of 3 CYP2E1 polymorphisms: CYP2E11A, CYP2E17A, and CYP2E17C by polymerase chain reaction technique in a sample of 100 healthy subjects representing Tibetan population. The frequencies of CYP2E11A, 7A, and 7C alleles were 0.705, 0.125, and 0.170, respectively. ⋯ Furthermore, the results of protein prediction revealed that the variant 6397G>A (rs61710826) could influence the protein structure and function. These findings in this study would be valuable for pharmacogenetics for drug therapy and drug discovery. However, further studies in larger samples are warranted to confirm our results.

Genome-wide association studies (GWAS) for spirometry parameters have been limited to forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and their ratio. This study examined to identify genetic variants associated with maximal voluntary ventilation (MVV), an important spirometry parameter presenting inspiratory muscle strength. A total of 8842 Korean subjects participated in the Korean Association REsource Consortium were used to identify nucleotide variants associated with MVV and other spirometry parameters through a GWAS. ⋯ The current study revealed 2 novel nucleotide variants as genetic association signals for MVV. The association signals were suggested specific for neuromuscular diseases with a restrictive ventilatory impairment. Further studies are required to understand underlying mechanisms for their influence to restrictive lung diseases.

Glucose metabolism status may play a predictive role in the severity of the complications among patients with type 2 diabetes mellitus (DM). However, few studies have focused on the prognostic value of glycosylated hemoglobin (HbA1c) and Homeostatic Model Assessment 2 for Insulin Resistance (HOMA2-IR) in patients with DM, non-ST-segment elevation infarction (NSTEMI), and single concomitant chronic total occlusion (CTO) following primary percutaneous coronary intervention (PCI). Short- and long-term prognostic value of HbA1c and HOMA2-IR in patients with DM with NSTEMI and single CTO who received primary percutaneous transluminal coronary intervention (pPCI). ⋯ Mean HOMA2-IR prior to pPCI was associated with revascularization (HR = 1.129; 95% CI = 1.008-1.265; P = .036) and ischemic stroke (HR = 1.276; 95% CI = 1.044-1.560; P = .017) during the 2.5 years follow-up period. Glucose metabolism status reflected by HbA1c and HOMA2-IR may provide prognostic value to patients with NSTEMI, type 2 DM, and single concomitant CTO following PCI. Therefore, patients with NSTEMI, CTO, and poor glycemic control should be carefully evaluated prior to PCI.
