HAVS at your feet? Vibration-white foot

At the Netherlands Center of Occupational Diseases earlier this year a question was asked about complaints of back and legs in a construction worker exposed to vibration through his feet. At that time no relevant literature was found in an initial search, now there is this interesting  case-report of a 54-year-old miner presented with a chief complaint of blanching and pain in his toes. He had a history of foot-transmitted vibration exposure over 18 years. The complaints at his feet were analogous to complaints of hand arm vibration syndrome (HAVS) occurring at the hands of workers handling vibrating tools. Read the rest of this entry »

New HSE review on HAVS

HSE published an extensive review on Hand Arm Vibration Syndrome (HAVS) recently. They introduce it like this:

“Health surveillance for those exposed to hand-arm vibration, and the diagnosis of hand-arm vibration syndrome (HAVS) is heavily dependent upon self-reporting of symptoms. However, this self-reporting may not be accurate for a number of reasons including the ability of individuals to recall symptoms, misunderstanding or misidentification of symptoms and fears regarding an individual’s job, or ongoing litigation. Therefore techniques that could be used to obtain better information, or tests that could be applied to obtain a more accurate diagnosis may be useful in this area.”

Work-related factors in carpal tunnel syndrome

forced gripCarpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome. Studies on selected occupational populations suggest an association of CTS with forceful repetitive work and vibration. The aim of this study was to investigate the relations between exposures to a single or a combination of physical work load factors and CTS. The researchers conclude that work tasks demanding handgrip with high forces or the use of vibrating tools are associated with CTS. The association is stronger if these work tasks are accompanied by repetitive movements of the hand or wrist.
