Objective: To systematically review the available evidence regarding steroid treatment for sudden sensorineural hearing loss (SSHL) and to update prior analyses when possible.
Data Sources: OVID Medline.
Review Methods: An electronic database search (OVID Medline) was performed with the objective of identifying all randomized controlled trials examining the use of steroids for the treatment of SSHL. The search was limited to English-language publications between January 1980 and June 2013. Reference lists were examined for additional articles.
Results: A total of 15 articles including 1,166 subjects were included in three separate analyses. Three articles (181 subjects) were included in the steroid versus placebo analysis, which resulted in an odds ratio of 1.52 (95% confidence interval [CI]: 0.83-2.77). Six articles (702 subjects) were included in the systemic versus intratympanic steroids analysis, which resulted in an odds ratio of 1.14 (95% CI: 0.82-1.59). Six articles (283 subjects) were included in the salvage treatment analysis, which resulted in an odds ratio of 6.04 (95% CI: 3.26-11.2).
Conclusions: A meta-analysis of randomized controlled trials does not support the use of steroids over placebo in this condition, a finding consistent with previous analyses. Although systemic or intratympanic steroid administration does not have a significant treatment effect, steroids for salvage treatment of patients failing traditional therapy appear to have an effect. However, this result should be interpreted with caution given the poor quality of component trials. Implications for clinical practice and future trial design are discussed.

Introduction: Post-stroke cognitive impairment (PSCI) and dementia affect short- and long-term outcome after stroke and can persist even after recover from a physical handicap. The process underlying PSCI is not yet fully understood. Transcranial Doppler ultrasound (TCD) is a feasible method to investigate cerebrovascular aging or dementia, through the pulsatility index (PI), the cerebrovascular reactivity (e.

Study Objective: The osmol gap can help detect and manage those with toxic alcohol exposure, and it is altered by all alcohols including ethanol. The optimal correction for ethanol that would allow accurate detection of an alternative alcohol is unclear.
Methods: We conducted a prospective cohort study to assess baseline variations in osmol gap, and then to assess the validity of 2 commonly used coefficients (correction factors) for ethanol.

ConspectusLithium-ion batteries (LIBs) based on graphite anodes are a widely used state-of-the-art battery technology, but their energy density is approaching theoretical limits, prompting interest in lithium-metal batteries (LMBs) that can achieve higher energy density. In addition, the limited availability of lithium reserves raises supply concerns; therefore, research on postlithium metal batteries is underway. A major issue with these metal anodes, including lithium, is dendritic formation and insufficient reversibility, which leads to safety risks due to short circuits and the use of flammable electrolytes.

Background: Pathogenic or null mutations in WRN helicase is a cause of premature aging disease Werner syndrome (WS). WRN is known to protect somatic cells including adult stem cells from premature senescence. Loss of WRN in mesenchymal stem cells (MSCs) not only drives the cells to premature senescence but also significantly impairs the function of the stem cells in tissue repair or regeneration.

Background: Management of the extensive soft tissue injuries remains a significant challenge in orthopedic and plastic reconstructive surgery. Since the thumb is responsible for 40% of the functions of the hand, saving and reconstructing a mangled thumb is essential for the patient's future.
Case Presentation: This case report describes the management of a severe occupational thumb injury in a 25-year-old white Persian male who sustained an occupational injury to his left thumb, resulting in extensive burn, crush injury to the distal and proximal phalanx, and severe soft tissue damage to the first metacarpal, thenar, and palmar areas.
