Objective. Follow-up of 80 patients using multiple program spinal cord stimulation (SCS). Methods. ⋯ Conclusions. In spinal cord stimulation the use of multiple electrodes and multiple stimulation programs, together with advanced programmability, increases paresthesia overlap, reduces pain scores, and may improve patient satisfaction with SCS therapy. This study indicates a significant patient preference for multiple program SCS, if patients are given the option to choose between a single program SCS system or a multiple program SCS system.

Sickle cell anaemia, a chronic and often debilitating disease, results from homozygosity for a single amino acid substitution in the beta-globin subunit of the haemoglobin molecule. Sickle haemoglobin (HbS), the product of this mutation, polymerises when deoxygenated, thus damaging the red blood cell and causing vaso-occlusive complications and haemolytic anaemia. Most cases of sickle cell anaemia are found in Africa. ⋯ Hydroxyurea is given to severely affected sickle cell anaemia patients in an attempt to prevent painful episodes, reduce hospital days, improve the patients' overall quality of life, and perhaps to prevent or provide some degree of end-organ damage stabilisation. Other novel therapies, such as bone marrow transplantation and gene therapy, pursue a cure. For these novel therapies to be effective on a global basis they must be amenable to underdeveloped and poorer countries of the world.

This prospective study was designed to determine the prevalence of lumbar facet joint pain in a consecutive series of patients with chronic low back pain treated at an interventional, multidisciplinary private pain management practice utilizing double diagnostic blocks, to determine the prevalence of false positive rate of uncontrolled facet joint blocks, and to determine the relationship of clinical features of responders and non-responders to double diagnostic blocks. One hundred and twenty patients with low back pain with or without lower extremity pain were selected. The procedure consisted of diagnostic blocks using lidocaine and bupivacaine on separate occasions, usually two weeks apart. ⋯ However, history of previous surgery showed a negative correlation as only 29% of the patients after previous surgery were positive in contrast to 51% of the nonsurgical population. The results of this study echo previous concerns of reliability of uncontrolled single blocks, history, and clinical features. This study demonstrated that the facet joint is a source of pain in 45% of the patients suffering with chronic low back pain in an interventional pain management setting in a private practice.

Post lumbar laminectomy syndrome with its resultant chronic low back pain is estimated to occur in 20% to 50% of the patients. Among various procedures available, lysis of epidural adhesions is considered as one of the effective therapeutic modalities of management in these patients, and may be performed either non-endoscopically or endoscopically. This retrospective evaluation included 120 post lumbar laminectomy patients who underwent either non-endoscopic adhesiolysis (Group I) or endoscopic adhesiolysis (Group II) with 60 consecutive patients in each group. ⋯ Cost effectiveness analysis showed Group I patients experiencing significant relief at a cost of $40 per week, with one year quality of life improvement for $2,080, whereas it was $135 per week improvement in Group II with a one year quality of life improvement at a cost of $7,020 with significant difference noted in cost effectiveness. In conclusion, non-endoscopic epidural adhesiolysis and administration of corticosteroids and hypertonic saline is a safe and cost effective procedure for relieving chronic intractable pain in post lumbar laminectomy patients who failed to respond to other modalities of treatment. Similarly, endoscopic adhesiolysis with the administration of corticosteroids is also a safe and possibly cost-effective technique for relief of chronic intractable pain failing to respond to other modalities of treatments.

Chronic neck pain, headache, and arm pain are some of the most common patient complaints confronting today's health care provider. Chronic neck pain is reported to be a frequency symptom in 34% of the general population with 14% of the general population reporting neck pain that lasted for more than 6 months. The magnitude of the problem is demonstrated by increase of cervical spine surgery by 45% and cervical fusion by 70% over a ten year period from 1979 through 1988. ⋯ Neural blockade in the cervical spine, though introduced in 1912, lagged behind that of the lumbar spine. At the present time, neural blockade is an extremely popular tool for diagnostic purposes in evaluation of neck pain, even though it has not developed a definitive role in the management of chronic neck pain and associated syndromes. The object of this review is to focus on various aspects of neural blockade in the management of chronic neck pain and associated syndromes including its rationale, clinical effectiveness, indications, and complications.
