Flushing as a side effect following lumbar transforaminal epidural steroid injection.

BACKGROUND: Epidural steroid injections (ESI) are commonly used in managing radicular pain. The risk of complications with epidural steroids is small, with the majority of complications being non-specific. Flushing is a known side effect of corticosteroid administration. The occurrence of flushing after epidural steroids has not been studied prospectively. OBJECTIVE: To compare flushing as a side effect of Betamethasone acetate/Betamethasone sodium phosphate (Celestone) vs. Methylprednisolone (DepoMedrol) in fluoroscopically guided epidural steroid injections. STUDY DESIGN: Non-concurrent Prospective Database Study METHODS: Two-hundred forty patients, who underwent epidural steroid injections in the University of Rochester Spine Center in the year 2001 were included. Eighty-one patients underwent epidural steroid injections with Celestone. One hundred fifty nine patients received treatment with Depo-Medrol. Patients were contacted two days after the procedure by a staff member and specifically asked about the presence of flushing following steroid injection. The answers were recorded as "yes" or "no". RESULTS: Out of 81 patients who underwent ESI with Betamethasone acetate/Betamethasone sodium phosphate, 13 reported a flushing reaction (16%). Out of 159 patients, who underwent ESI with Methylprednisolone, 14 reported a flushing reaction (9%). This side effect difference was not statistically significant (p < 0.143 and odds ratio of 0.505). The overall incidence of flushing was approximately 11%. CONCLUSION: Flushing reaction appears to be more widespread than previously assumed, with an overall incidence of 11%. There was no significant difference in self-reported flushing reactions following lumbar epidural steroid injections using either betamethasone or methylprednisolone.

Provocative cervical discography symptom mapping.

BACKGROUND CONTEXT: In a small prospective study assessing 10 symptomatic and 10 asymptomatic subjects, Schellhas et al. compared cervical discography to magnetic resonance imaging. Within that study he reported on the distribution of pain for the C3-C4 to C6-C7 levels. Four years later, Grubb and Ellis reported retrospective data from his 12-year experience using cervical discography from C2-C3 to C7-T1 in 173 patients. To date, no large prospective study defining pain referral patterns for each cervical disc has been performed. PURPOSE: To conduct a prospective visual and statistical descriptive study of pain provocation of a cohort of subjects undergoing cervical discography. STUDY DESIGN/SETTING: Prospective multicenter descriptive study. METHODS: Pain referral maps were generated for each disc level from patients undergoing cervical discography with at least two levels assessed. If concordant pain was reproduced in a morphologically abnormal disc, the subject immediately completed a pain diagram. An independent observer interviewed the subject and recorded the location of provoked symptoms. Visual data were compiled using a body sector bit map, which consisted of 48 clinically relevant body regions. Visual maps with graduated color codes and frequencies of symptom location at each cervical disc level were generated. RESULTS: A total of 101 symptom provocation maps were recorded during cervical discography on 41 subjects. There were 10 at C2-C3, 19 at C3-C4, 27 at C4-C5, 27 at C5-C6, 16 at C6-C7 and 2 at C7-T1. Predominantly unilateral symptoms were provoked just as often as bilateral symptoms. The C2-C3 disc referred pain to the neck, subocciput and face. The C3-C4 disc referred pain to the neck, subocciput, trapezius, anterior neck, face, shoulder, interscapular and limb. The C4-C5 disc referred pain to the neck, shoulder, interscapular, trapezius, extremity, face, chest and subocciput. The C5-C6 disc referred pain to the neck, trapezius, interscapular, suboccipital, anterior neck, chest and face. The C6-C7 disc referred pain to the neck, interscapular, trapezius, shoulder, extremity and subocciput. At C7-T1 we produced neck and interscapular pain. Visual maps with graduated color codes and frequencies of symptom location at each cervical disc level were generated. CONCLUSIONS: In conclusion, these results confirm the observations of prior investigators that cervical internal disc disruption can elicit axial and peripheral symptoms. The particular patterns of pain generation allow the discographer to preprocedurally anticipate disc levels to assess. With these data, the number of disc punctures that are required can be limited rather than routinely assessing all cervical discs.

Genetic engineering in agriculture and corporate engineering in public debate: risk, public relations, and public debate over genetically modified crops.

Corporations have long influenced environmental and occupational health in agriculture, doing a great deal of damage, making substantial profits, and shaping public debate to make it appear that environmental misfortunes are accidents of an otherwise well-functioning system, rather than systemic. The debate over the genetically modified (GM) crops is an example. The largest producer of commercial GM seeds, Monsanto, exemplifies the industry's strategies: the invocation of poor people as beneficiaries, characterization of opposition as technophobic or anti-progress, and portrayal of their products as environmentally beneficial in the absence of or despite the evidence. This strategy is endemic to contemporary market capitalism, with its incentives to companies to externalize health and environmental costs to increase profits.
