Benign paroxysmal positional vertigo (BPPV) is among the most common inner ear diseases. Although BPPV is one of the most common causes of dizziness, its pathogenesis remains unknown. Air pollutants might reach the middle ear through the eustachian tube and be absorbed into the inner ear through the round window membrane, increasing the risk of BPPV. We investigated the relationship between air pollution and BPPV risk. Data were extracted from the Korean Health Insurance Review and Assessment Service database, which contains health claims information of the entire South Korean population. Variables of interest included the number of patients diagnosed with BPPV in Seoul, South Korea, patients' clinical and demographic characteristics, and osteopenia status. Seoul's daily air pollution indicators, including SO2, CO, O3, NO2, PM10, and PM2.5, were obtained from the Korea Environment Corporation website. Overdispersed Poisson regression analysis was performed. In the multivariable analysis, NO2 air concentration (ppb) was associated with increased incidence of BPPV. In analysis stratified by gender, levels of NO2 were associated with increased incidence of BPPV in both men and women. Savolitinib nmr In the analysis stratified by age, NO2 air concentration was associated with increased incidence of BPPV among all adults over the age of 19 years. In the analysis stratified by osteopenia status, NO2 was associated with increased incidence of BPPV in patients with and without osteopenia. Air levels of NO2 were associated with increased incidence of BPPV in the present study. This finding contributes toward a better understanding of BPPV pathogenesis and improved prevention and management of this condition.The pyrethroid imiprothrin is widely used worldwide for control of insects in the agriculture and public health sectors. No sufficient information is however available concerning detoxification gene expression, i.e., cytochrome P450 1A2 (CYP1A2) and metallothionein 1a gene, oxidative stress, lipid peroxidation, DNA damage, cytotoxicity, genotoxicity, and organ injury induced by imiprothrin in mammals. This study is designed to explain the mechanism of imiprothrin induced detoxification gene expression, DNA damage, cytotoxicity, genotoxicity, and organ toxicity in male rats. The benchmark dose (BMD) was calculated to find the best sensitive markers to imiprothrin toxicity. Imiprothrin was injected intraperitoneally (i.p.) into male rats once a day for 5 days with doses of 19, 38, and 75 mg/kg body weight (b.wt.). Imiprothrin caused a significant increase in lipid peroxidation and changes in oxidative stress biomarkers in treated rats. Significant dose-dependent changes in the liver and kidney biomarkers were observed. Histopathological alterations were seen in the liver and kidney tissue of male rats. Imiprothrin also significantly increased chromosomal aberrations (CA) and micronuclei in bone-marrow cells, and induced lipid peroxidation, oxidative stress, cytotoxicity, and liver and kidney dysfunction, and damage. Imiprothrin induced DNA damage and over detoxification gene expression of CYP1A2 and metallothionein 1a gene in hepatocytes of male rats. Imiprothrin thus shows clastogenic and genotoxic potential. The mechanism for hepatorenal toxicity and injury, genotoxicity/cytotoxicity of imiprothrin might be due to enhanced lipid peroxidation, and oxidative stress associated with overproduction of free radicals, especially reactive oxygen species, and an imbalance in redox status. From the BMD models, aspartate aminotransferase (AST), total protein, uric acid, superoxide dismutase (SOD), and micronuclei (MPEs) were very sensitive markers to imiprothrin toxicity.
A significant proportion of patients undergoing catheter ablation for atrial fibrillation (AF) experience arrhythmia recurrence. This is mostly due to pulmonary vein reconnection (PVR). Whether mapping using High-Density Wave (HDW) technology is superior to standard bipolar (SB) configuration at detecting PVR is unknown. We aimed to evaluate the efficacy of HDW technology compared to SB mapping in identifying PVR.

High-Density (HD) multipolar Grid catheters were used to create left atrial geometries and voltage maps in 36 patients undergoing catheter ablation for AF (either due to recurrence of an atrial arrhythmia from previous AF ablation or de novo AF ablation). Nineteen SB maps were also created and compared. Ablation was performed until pulmonary vein isolation was achieved.

Median time of mapping with HDW was 22.3 [IQR 8.2] min. The number of points collected with HDW (13299.6±1362.8 vs 6952.8±841.9, p<0.001) and used (2337.3±158.0 vs 1727.5±163.8, p<0.001) was significantly higher compared to SB. Moreover, HDW was able to identify more sleeves (16 for right and 8 for left veins), where these were confirmed electrically silent by SB, with significantly increased PVR sleeve size as identified by HDW (p<0.001 for both right and left veins). Importantly, with the use of HDW, the ablation strategy changed in 23 patients (64% of targeted veins) with a significantly increased number of lesions required as compared to SB for right (p=0.005) and left veins (p=0.003).

HDW technology is superior to SB in detecting pulmonary vein reconnections. This could potentially result into a significant change in ablation strategy and possibly to increased success rate following pulmonary vein isolation.

There is a relative paucity of data on ante-mortem clinical characteristics of young (age 1 to 35years) sudden death (SD) victims. The aim of the study was to characterize ante-mortem characteristics of SD victims, in a selected national cohort identified by a web search.

A dataset of all SD (January 2010 and December 2015) was built from national forensic data and medical records, integrated with Google search model. Families were contacted to obtain consent for interviews. Data were obtained on ante-mortem symptoms. ECG characteristics and autopsy data were available.

Out of 301 SD cases collected, medical and family history was available in 132 (43.9%). Twenty-eight (21.1%) had a positive family history for SD. SD occurred during sport/effort in 76 (57.6%). One hundred twelve (85%) SD cases had no prior reported symptoms. Autopsy data were available in 100/132 (75.8%) cases an extra cardiac cause was identified in 20 (20%). Among the 61 cases with a cardiac diagnosis, 21 (34%) had hypertrophic cardiomyopathy.
