Was Beethoven’s deafness caused by lead toxicity?

3 out of 5 stars Lead and the Deafness of Ludwig Van Beethoven. Stevens MH et al. Laryngoscope 2013 Nov;123:2854-2858. Abstract Beethoven was 27 when he first experienced tinnitus and high-frequency hearing impairment. These symptoms progressed slowly until the famous incident in 1824 when the composer, attending the first performance of his Ninth Symphony, he was not able to hear the thunderous applause that followed. The authors of this interesting article consider some previously theories proposed to explain Beethoven’s deafness, and find reasons to rule them out: Autoimmune hearing loss – While this progresses rapidly over weeks or months, Beethoven’s symptoms worsened slowly over years. Mercury toxicity from treatment for syphilis - There is no evidence that Beethoven had syphilis, and no mercury was detected in samples of his bone or hair. Otosclerosis – Arguing against this is the fact that findings consistent within this diagnosis were not documented at autopsy. The authors argue, rather, that Beethoven’s deafness was the result of chronic lead toxicity. In fact, analysis of a sample of Beethoven’s hair at the Argonne National Laboratory did demonstrate the presence of lead. Exposure might have resulted from the composer’s well-known fondness for wine, which was often contaminated with the heavy metal. This theory had been rejected in the past, because there is no evidence that Beethoven had other neurological mani...

Chemicals used as cooling agents in refrigeration and air-conditioning units can be deadly if inhaled. This rarely occurs by accident, but some people inhale these chemicals, commercially known as Freon, to get high. Read on to find out about the dangers and what to do if someone shows signs of refrigerant poisoning.

The public could be at risk of eating contaminated and diseased meat because of failings at slaughterhouses, according to a survey of meat hygiene inspectors published today (Sunday) by UNISON. The findings – summarised in the report A Raw Deal – highlight concerns that contaminated and diseased meat could be cleared as fit for human consumption. It found that virtually every meat hygiene inspector surveyed (98%) said that the meat industry couldn’t be trusted to ensure no faecal contamination was present before meat was sold on to consumers. In addition, 96% of the inspectors thought that staff directly ...

Conclusions: These data demonstrate that hyperbaric oxygen is associated with reduced acute and reduced 1-year mortality. Further studies are needed on the mortality effects of hyperbaric oxygen therapy in carbon monoxide poisoning.

Publication date: 23 November 2018 Source:Chemical Engineering Science, Volume 190 Author(s): Jinyong Luo, Krishna Kamasamudram, Neal Currier, Aleksey Yezerets We identified a new acidic feature in Cu/SSZ-13 catalysts, related to the presence of two distinct desorption peaks in the NH3-TPD profiles, and to the changes in their relative intensity in response to mild hydrothermal aging (Luo et al., 2017). In this work, we have translated those findings into a sensitive laboratory diagnostic methodology for quantifying cumulative aging exposure, based on the ratio of the two NH3-TPD peaks. We have also addressed some practic...

Authors: Wolff DW, Lee MH, Jothi M, Mal M, Li F, Mal AK Abstract Alveolar rhabdomyosarcoma (aRMS) is an aggressive subtype of the most common soft tissue cancer in children. A hallmark of aRMS tumors is incomplete myogenic differentiation despite expression of master myogenic regulators such as MyoD. We previously reported that histone methyltransferase KMT1A suppresses MyoD function to maintain an undifferentiated state in aRMS cells, and that loss of KMT1A is sufficient to induce differentiation and suppress malignant phenotypes in these cells. Here, we develop a chemical compound screening approach using MyoD-re...
