<unk>  <unk> , or Shoenfeld's<unk> , is a hypothesised<unk>  disorder proposed by Israeli immunologist Yehuda Shoenfeld in 2011. According to Shoenfeld, the<unk>  is triggered by exposure to<unk>  and includes four conditions: "post-vaccination symptoms", macrophagic myofasciitis, Gulf war<unk> , sick building<unk> , and siliconosis. Shoenfeld alleges that the<unk>  is caused by<unk>  such as silicone, tetramethylpentadecane, pristane, and aluminum. However, causality is difficult to prove because<unk>  only occurs in a small fraction of patients exposed to these<unk> . Additionally, proponents of this theory allege that the disorder can manifest anywhere from 2 days to 23 years after exposure. Shoenfeld has also named Sjögren's<unk>  as potentially being another facet of<unk> . However, apart from the theoretical concept of<unk> , there is a lack of reproducible evidence for any causal relationship between<unk> and<unk>  condition. A study of 18,000 people showed that there is no merit to the theory of<unk> .
