Efficacy of destruction of dorsal root ganglia with local doxorubicin Injection under the guidance of CT for postherpetic neuralgia involving thoracic back region
Bibliographic record
Abstract
Objective To evaluate the efficacy of destruction of dorsal root ganglia with local doxorubicin injection guided by CT for postherpetic neuralgia involving thoracic back region. Methods One hundred and fifty patients suffering from postherpetic neuralgia in thoracic back region were randomly divided into 3 groups ( n = 50 each): group A oral medicine; B and C groups undergoing local injection under the guidance of C-arm and CT respectively + oral medicine. Three spinal segments severely affected by herpes virus were chosen for paravertebral puncture. 1% lidocaine 1 ml was injected at each segment as test dose. Fifteen minutes later doxorubicin 3.3 mg and betamethasone compound 4.7 mg were injected at each segment if no side-effect occurred. All 3 groups were given oral medicine according to the intensity of pain after local injection. The number of patients who exited from the study because of the side effects of oral medicine was recorded. VAS, sleep interference score (SIS) and a short form of McGill pain questionnaire (SF-MPQ) were used to evaluate the efficacy of the treatment the day before (baseline), 24 h, 1 week, 1, 3 and 6 months after local injection. The dosage of oxycodone extended-release tablets and gabapentin was recorded, and also the incidence of pneumothorax within 12 h after local injection. Results The exit rate, VAS, SIS and SF-MPQ scores, dosage of oxycodone extended-release tablet and gabapentin were significantly lower in B and C groups than in group A, but there was no significant difference between the 2 groups. The incidence of pneumothorax was 10% in group B but no pneumothorax developed in group C.Conclusion Destruction of dorsal root ganglia with local doxorubicin injection guided by CT is more effective for the treatment of postherpetic neuralgia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
