Neuropathic pain in cancer can result in severe debilitation to a patient with limited treatment options. Interventional modalities like nerve destruction can provide relief but at the expense of motor paralysis. Sympathetic pain is often an undiagnosed and undertreated condition that may accompany cases of chronic pain. We describe a case of severe neuropathic pain in brachial plexopathy in a middle-aged woman caused by metastatic breast cancer that was managed by chemical neurolysis of brachial plexus. Residual pain was treated by neurolysis of stellate ganglion due to the presence of sympathetic pain. This case report highlights the importance of the dual nature of pain and its management by chemical neurolysis in severe refractory neuropathic and sympathetic mediated pain.
ABSTRACT
OBJECTIVE: Discogenic pain is common cause of low back ache and may result in significant morbidity. Platelet-rich plasma (PRP) is an upcoming regenerative therapy that has treatment potential for this condition. The objective of this study was to correlate platelet concentration in intradiscal PRP injection with improvement in low back pain and functional status at three and six months. DESIGN: Prospective single-arm interventional study. SETTING: Outpatient pain clinic and operation theater. SUBJECTS: Twenty-five patients with discogenic pain diagnosed by clinical means and imaging with confirmation by provocative discography were recruited. METHODS: The patients received PRP injection at a single or multiple disc levels. Preprocedure numerical rating scale (NRS) pain scores and Oswestry Disability Index (ODI) scores were calculated. Platelet counts of patients and PRP samples were measured. At three and six months postprocedure, NRS and ODI scores were measured, and improvement in these scores was correlated with platelet concentrations in the PRP sample. RESULTS: Twenty patients completed the study. The improvement in NRS and ODI scores positively correlated with platelet concentrations in the PRP sample. We determined the correlation coefficient (r) of platelet concentrations with a reduction in NRS at three months (r = 0.65) and six months (r = 0.73) and in ODI score at three months (r = 0.72) and six months (r = 0.7). CONCLUSIONS: This study supports the use of intradiscal PRP for treatment of discogenic pain with preferably higher platelet counts to elicit a favorable response.
