Effects of acupuncture at myofascial trigger points combined with sling exercise therapy on clinical recovery and cervical spine biomechanics in patients with cervical spondylotic radiculopathy.

OBJECTIVE: This research aimed to ascertain the effects of acupuncture at myofascial trigger points (MTrPs) in combination with sling exercise therapy (SET) on the clinical recovery and cervical spine biomechanics in patients with cervical spondylotic radiculopathy (CRS). METHODS: Eighty patients with CSR were divided into Group A and Group B. Group A was treated with acupuncture at MTrPs, and Group B was treated with acupuncture at MTrPs combined with SET. The cervical spine function, pain level, cervical spine biomechanics and the occurrence of complications were compared between the two groups before and after treatment. RESULTS: After treatment, the Japanese Orthopaedic Association scores, Clinical Assessment Scale for Cervical Spondylosis scores, cervical forward flexion angle, posterior extension angle, left lateral flexion angle, right lateral flexion angle, left lateral rotation angle, and right lateral rotation angle of the Group B were raised, and the Neck Disability index, Visual Analogue Scale scores, and Neck Pain Questionnaire scores were reduced versus those of the Group A. The difference in complication rates between the two groups was not of statistical significance. CONCLUSION: Acupuncture at MTrPs combined with SET promotes functional recovery of the cervical spine, reduces pain, and improves cervical spine biomechanics in patients with CRS.

Effectiveness of clotting factor replacement therapy after antivenom treatment on coagulopathic envenomation following green pit viper bites: a retrospective observational study.

BACKGROUND: Green pit vipers (GPVs), namely Trimeresurus albolabris and Trimeresurus stejnegeri accounts for most snakebites in Southern China. Green pit viper venom contains thrombin-like enzymes, resulting in defibrination syndrome. Using of clotting factor replacement after antivenom administration is controversial. The objective of this study was to investigate the effects of clotting factor replacement in coagulopathic patients with T. albolabris and T. stejnegeri bites after antivenom administration. METHODS: We retrospectively reviewed 123 patients who were bitten by T. albolabris and T. stejnegeri and were admitted to the Emergency Department of a hospital in Guangzhou, Southern China, from 2013 to 2019. Recovery of prothrombin time (PT) and fibrinogen level were compared among (1) fresh-frozen plasma (FFP) group; (2) cryoprecipitate (cryo) group; (3) FFP and cryo group; and (4) control group after antivenom administration. RESULTS: The incidence of coagulopathy was 31%. Persistent and late coagulopathy were the most common patterns among four groups. The median reduction in PT was 20.1 ± 31.2 s for FFP and cryo group. The median increase in fibrinogen level was very small: 0.05 ± 0.20 g/L for FFP group, 0.09 ± 0.37 g/L for cryo group and 0.07 ± 0.31 g/L for FFP and cryo group, respectively. The percentage of unimproved PT was markedly higher in the FFP and cryo group than the control group (P = 0.01 by log-rank test, P = 0.02 by Gehan-Breslow-Wilcoxon test). The percentage of unimproved fibrinogen level tended to be worse in the FFP and cryo group than the control group, but the different was marginal (P = 0.05 by Gehan-Breslow-Wilcoxon test, P = 0.07 by log-rank test). A total of 7.8% (7/90) of the patients in the clotting factor replacement groups developed anaphylaxis and heart failure. CONCLUSION: There is no improvement in coagulopathy profile in patients with T. albolabris and T. stejnegeri bites who received clotting factor replacement after antivenom administration. But the results from GPVs may not be generalized to other species of venomous snakes.
