Unfortunately he failed to attend any further follow-up and was re-referred 12 months later with on-going pain at the base of the thumb.

Caries is a multi-factorial disease and its effects can range from mild discomfort, to on-going pain that affects quality of life [ 3].
Persistent or on-going pain was perceived to be a significant marker of illness severity, and one that often required the help of a health professional.
This work adds considerably to the field, by demonstrating its suitability to real-world, clinically relevant functional indices of on-going pain.
That said, the TME model provides an ideal test-bed for the development of ASL as a robust, ethical means of eliciting on-going pain secondary to tissue trauma [Howard et al., 2011; Kupers and Kehlet, 2006; Tracey and Johns, 2010] and for testing the sensitivity and specificity of the GPC technique to detect inescapable on-going pain.
Pain intensity following TME has been extensively evaluated and shown to produce moderate-to-severe on-going pain between 3 and 5 hrs following surgery [Barden et al., 2004].
In summary, we have demonstrated how state of the art MPC methods can be applied to ASL data to provide single-subject predictions regarding the probability of an individual experiencing moderate to severe postoperative on-going pain.
Since spontaneous activity is necessary for the perception of chronic, on-going pain in MIA joints [ 11], intrathecal A-803467 may be required to address the problem of pain at rest in OA patients.
However, in 10 cases the consequences were permanent, as on-going pain and injuries such as vaginal and anal tearing, physical impairment or even fatal consequences in 6 cases.
