It has been reported that in 62.5% of cases of incurable cancer pain, the complaint is due to myofascial pain syndrome. Trigger point injections using dibucaine hydrochloride help patients with such cancer pain. This study evaluated the efficacy of trigger point injections for alleviating pain in patients with advanced cancer.

METHODS:

Twenty patients with advanced cancer who had a life expectancy of 6 months or less and had been diagnosed with myofascial pain syndrome were treated with trigger point injections. Prior to treatment, a Visual Analog Scale (VAS) was used to measure the resting pain level and discomfort upon application of pressure on the site of pain. These values were compared with last treatment measurements.

RESULTS:

The mean pre-treatment VAS scores for pain at rest and upon application of pressure on the pain site were 7.3 and 9.0, respectively. These scores decreased significantly to 1.95 and 3.2, respectively, after the treatment (P<0.05).

CONCLUSION:

Trigger point injection is an alternative and effective pain control modality for advanced cancer patients with myofascial pain syndrome.

For the treatment of oral mucositis, carrageenan microspheres containing allopurinol and local anesthetic agents, such as lidocaine hydrochloride, dibucaine hydrochloride and tetracaine hydrochloride were prepared using a spray-drying method. As base materials, kappa-carrageenan and iota-carrageenan were evaluated, since carrageenan mitigates bitter taste of lidocaine hydrochloride, dibucaine hydrochloride and tetracaine hydrochloride. The microspheres were spherical and their average diameters were about 10 microm. The drug loading efficiency was more than 70%. Allopurinol and local anesthetic agents became amorphous by the spray drying. Allopurinol and the local anesthetic agents were released from the microspheres for at least 400 min when iota-carrageenan was used as a base material. On the other hand, the release was prolonged to 600 min when kappa-carrageenan was used. The microspheres were spread and made membranes at the air/water interfaces immediately after dropped on the water surfaces. The properties of the microspheres such as dispersing efficacy and membrane production on the water surfaces suggest that the microspheres can uniformly cover inner surfaces of oral cavity to prevent and treat oral mucositis.
