INTRODUCTION: The TASER® conducted electrical weapon (CEW) is best known for delivering electrical pulses that can temporarily incapacitate subjects by overriding normal motor control. The alternative drive-stun mode is less understood and the goal of this paper is to analyze the distribution of currents in tissues when the CEW is operated in this mode. METHODS AND RESULTS: Finite element modeling (FEM) was used to approximate current density in tissues with boundary electrical sources placed 40 mm apart...

Small swine are the most common model now used for electrical safety studies. Because of the significant anatomical and electrophysiological differences and the effect of animal size on the ventricular fibrillation (VF) threshold, there are concerns that these differences may exaggerate the risks of electrical devices to humans. We chose, as an illustrative and relevant example, swine studies of the TASER® conducted electrical weapon (CEW) as it has numerous published VF studies. We reviewed the published electrical swine safety studies for CEWs and compared them to finite element modeling studies, electrical safety standards, and epidemiological experience from field usage...

Ovarian cancer has a unique pattern of metastatic spread, in that it initially spreads locally within the peritoneal cavity. This is in contrast to most other cancer types, which metastasize early on via the bloodstream to distant sites. This unique behavior opens up an opportunity for local application of both therapeutic and imaging agents. Upon initial diagnosis, 75% of patients already present with diffuse peritoneal spread involving abdominal organs. Complete resection of all tumor implants has been shown to be a major factor for improved survival...

BACKGROUND: Failure rates of second-line boosted protease inhibitor antiretroviral therapy regimens in children rise over time. Therapeutic drug monitoring can contribute to assessments of adherence. The authors assessed the performance characteristics of the US DHHS-recommended lopinavir (LPV) concentration of 1.0 mg/L for predicting virologic failure (VF) and intermediate- to high-level LPV resistance in Asian children. METHODS: LPV concentration, HIV RNA level, and adherence data from study participants in Thailand, Vietnam, and Indonesia receiving second-line LPV-based ART and followed for ≥24 weeks were analyzed...

AIM: Current study planned to investigate histologic findings and differences in carpal tunnel syndrome (CTS) with diabetes mellitus, thyroid disease and idiopathic CTS patients. MATERIAL AND METHODS: Subsynovial connective tissue samples of 51 idiopathic CTS patients, 58 patients with diabetes mellitus and CTS, 16 patients with hypothyroidism and CTS were evaluated for this study. The histopathologic examination parameters were number of fibroblasts, size of collagen fibers, vascular changes (vascular proliferation, intimal thickening and changes of vessel structures), edema and inflammatory infiltration...

INTRODUCTION: Despite research demonstrating the overall safety of Conducted Electrical Weapons (CEWs), commonly known by the brand name TASER(®), concerns remain regarding cardiac safety. The addition of cardiac biomonitoring capability to a CEW could prove useful and even lifesaving in the rare event of a medical crisis by detecting and analyzing cardiac rhythms during the period immediately after CEW discharge. OBJECTIVE: To combine an electrocardiogram (ECG) device with a CEW to detect and store ECG signals while still allowing the CEW to perform its primary function of delivering an incapacitating electrical discharge...

Concern has been raised over the infection risk of the TASER electrical weapon since the probes penetrate the skin. The manufacturing process produces unsterilized probes with a 5% rate of Staphylococcus aureus contamination. Voluntary recipients (n = 208) of probe exposures were surveyed and there were no self-observations of infection. With over 3.3 million probe landings, there have been 10 case reports of penetrations of sensitive tissue with no reported infections. The electrical field was modeled and found that the electrical pulses generate a field of over 1200 V/mm on the dart portion...

INTRODUCTION: While generally reducing morbidity and mortality, electrical weapons have risks associated with their usage, including eye injuries and falls. With sufficient probe spread, an uncontrolled fall to the ground typically occurs along with the possibility of a fatal brain injury. METHODS: We analyzed possible risk factors including running and elevated surfaces with established head-injury criteria to estimate the risk of brain injury. We searched for cases of arrest-related or in-custody death, with TASER(®) electrical weapon usage where fall-induced injuries might have contributed to the death...

Concerns of violence in hospitals warrant examination of current hospital security practices. Cross-sectional survey data were collected from members of a health care security and safety association to examine the type of personnel serving as security in hospitals, their policies and practices related to training and weapon/restraint tool carrying/use, and the broader context in which security personnel work to maintain staff and patient safety, with an emphasis on workplace violence prevention and mitigation...

Use of a conducted-energy device (CED), or Taser, by law enforcement officers (LEOs) is recommended over more lethal forms of force. LEOs interact with a wide variety of people including individuals with mental illness and those with substance use disorders. The literature is devoid of data regarding the effect of CEDs on this special population. We used data collected by LEOs from 2008 to 2009. There were 233 cases over the two-year period. Of the 233 individuals on whom the Taser was used, 38 had a mental illness and 91 were under the influence of substances (not mutually exclusive)...

OBJECTIVE: To investigate whether an intensive early rheumatoid arthritis (RA) treat-to-target (T2T) strategy could be improved through the use of musculoskeletal ultrasound (MSUS) assessment of disease activity. METHODS: 111 newly diagnosed patients with RA or undifferentiated arthritis (symptom duration <1 year) were randomised to strategies that aimed to attain either DAS28-erythrocyte sedimentation rate (ESR)<3.2 (control) or a total power Doppler joint count≤1 during a combined DAS28-ESR/MSUS assessment (intervention)...

Given the higher incidence of non-invasive colorectal tumors due to the further implementation of screening techniques, multiple endoscopic techniques have emerged for its resection. Recently described, transanal submucosal endoscopic resection (TASER) pools the concepts of endoscopic resection with the transanal surgery. We report our initial experience and reflections on this new technique.

OBJECTIVE: Carpal tunnel syndrome (CTS) is an entrapment neuropathy which is caused by the disruption of blood supply in the median nerve under transverse carpal ligament. Systemic factors facilitate the formation of the syndrome. In this study, neovascularization in the subsynovial tissue and proliferative activity in the stroma are analyzed within the cases of diabetic and idiopathic CTS. MATERIALS AND METHODS: Subsynovial connective tissue samples of 30 diabetes mellitus patients with CTS and 30 patients with idiopathic CTS were evaluated...

AIMS: Acute myocardial infarction is a serious acute cardiac disorder and heart disease is still a major public health problem in adults. We investigated the effects of embelin (EMB) and carnosic acid (CA) in animals with isoproterenol (ISO)-induced myocardial injury. MAIN METHODS: Adult male Wistar-Albino rats were divided into four groups: control, ISO, ISO with EMB, and ISO with CA. Before myocardial injury was induced, drugs were administered by oral gavage...

The TASER(®) conducted electrical weapon (CEW) delivers electrical pulses that can temporarily incapacitate subjects. We analyzed the cardiac fibrillation risk with TASER CEWs. Our risk model accounted for realistic body mass index distributions, used a new model of effects of partial or oblique dart penetration and used recent epidemiological CEW statics.
