Background and Objectives: Achieving adequate pain reduction in the acute phase of herpes zoster is essential for preventing postherpetic neuralgia (PHN). For this purpose, appropriate antiviral medications, oral analgesic medications, and various nerve block methods could be applied. Erector spinae plane block (ESPB) is a simple, novel ultrasound-guided block technique, and its use has increased because the procedure is convenient and relatively safe. Although several cases have reported the zoster-associated pain (ZAP) control effect of ESPB, the efficacy of ESPB has not been compared with that of other types of nerve blocks for managing ZAP. This study aimed to compare the efficacy of ESPB with that of other types of nerve blocks for managing ZAP. Study Design: Retrospective case-control study. Materials and Methods: Medical records of 53 patients with acute thoracic herpes zoster were reviewed. We divided the participants into two groups: patients who received transforaminal epidural injection (TFEI) (n = 32) and those who received ESPB (n = 21). The efficacy of the procedure was assessed by a numerical rating scale (NRS) and by recording patient medication doses before the procedure and at 1 week, 1 month, 2 months, and 3 months after the procedure. Results: The time required for pain intensity to decrease to NRS ≤ 2 was not significantly different between the groups. The rate of medication discontinuation also was not different between the groups. There was no significant difference between the two groups in the proportion of clinically significant PHN (NRS ≥ 3) at any time point. Limitations: The relatively small sample size from a single center and the retrospective nature of the study served as limitations. Conclusions: The clinical effects of ESPB and TFEI were similar in patients with acute thoracic herpes zoster. ESPB could be considered an interventional option for ZAP management.

UNASSIGNED: This study aimed to compare parasagittal interlaminar (PS) and transforaminal (TF) epidural steroid injections for unilateral L5 and S1 radicular lower back pain in terms of patient comfort, efficacy, safety, contrast enhancement, and radiation exposure.
UNASSIGNED: This was a prospective randomized single-blind study. A total of 59 participants were included in this study. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were obtained. A comfort questionnaire was administered to all participants. The total fluoroscopy time and contrast distribution levels were recorded.
UNASSIGNED: Pre- and post-treatment VAS scores were similar between the groups. The ODI scores increased in favor of the PS group at week 2 (P < 0.041); however, there was no difference between the two groups at other times. The VAS and ODI scores improved significantly with treatment in both the groups (P < 0.001). Total fluoroscopy time was shorter in the PS group (P < 0.001). PS application was more comfortable (P < 0.001). While no complications were observed in the PS group, three complications occurred in the TF group. Anterior epidural contrast spread to three or more levels was observed in 57% of the participants in the PS group, whereas no spread to more than two levels was observed in the TF group.
UNASSIGNED: The PS epidural approach is superior to the TF approach in terms of a low incidence of side effects, less radiation exposure, better patient comfort, higher epidural contrast spread, and single-level needle access.

To show that with C5 radiculopathy and profound neurological deficit, good outcomes can be obtained with injection therapy.
We present two cases of cervical radiculopathy secondary to disc prolapse associated with profound neurological deficit. In both cases, cervical injection therapy was used as the primary management.
The two cases presented were both male, 59 and 36 years, and were diagnosed on MRI imaging with C4/5 disc prolapses. They presented with severe motor deficit and were both treated with foraminal epidural steroid injections, one of the patients also had two previous injections elsewhere prior to the first review. In both patients, pain and neurological deficit improved in a timely manner resulting in full recovery. MRI taken after recovery showed complete resorption of the disc prolapse in both cases.
In C5 radiculopathy, even with severe neurological deficit, cervical injection therapy should be considered. These cases illustrate that excellent results can be obtained without the need for open surgery with its inherent risks.

Corticosteroids been used frequently in pain treatments since the middle of last century (1952). Due to a review of the complications as a result of their application in epidural injections, the United States of America Food and Drug Administration (FDA) issued an «alert controversy» requesting that a warning label should be added to injectable corticosteroids, where risks must be described (loss of sight, brain damage, paralysis and death) when administering by this route. It must be mentioned that there are different types of corticosteroids with diverse characteristics, which as a result, may produce different side-effects. Due to the aforementioned developments, the controversies that have arisen, and the lack of well-conducted studies on the use of steroids in epidural injections, we must begin by reviewing their indications in different pain conditions.
