Insurance court dismissed claim for work injury compensation due to lack of causal link between work and illness.

The Insurance Court dismissed the claimant's request for work injury compensation regarding his right shoulder inflammation. The claimant argued that his work duties starting in April 1978 aggravated his pre-existing condition diagnosed in October 1978, while the insurer denied liability citing no direct causal connection. The court ruled that the medical evidence failed to establish a sufficient causal link between the specific work activities and the onset of the inflammation.
