The role of GABAergic cell transplantation in improving neuropathic pain is controversial. We comprehensively searched the relevant literature to identify animal studies of GABAergic cell transplantation that recorded pain behaviors as an outcome according to the Cochrane Handbook 5.0.2. Controlled studies assessing the administration of GABAergic neurons or GABAergic neuronal progenitor cells to rat or mouse neuropathic pain animal models were included. Basic design information and mechanical allodynia thresholds and heat hyperalgesia thresholds data were collected. The risk of bias for the animal experiments was assessed according to the SYRCLE's tool. This study included 10 full-text articles. GABAergic cells transplantation leads to a statistically significant improvement of allodynia (SMD = 5.26; 95% confidence interval: 3.02-7.51; < 0.001) and hyperalgesia (SMD: 4.10; 95% confidence interval: 1.84-6.35; < 0.001). Differentiated GABAergic cells and without antibiotics using may have a better effect for improving neuropathic pain. GABAergic cell transplantation is a promising treatment for improving neuropathic pain. This systematic review and meta-analysis evaluated the effects of GABAergic cell transplantation on neuropathic pain, which can guide future clinical trials and possible clinical treatments, and better attenuate neuropathic pain caused by abnormal circuit hyperexcitability.

Chronic intraoral neuropathic pain (NP), often developing post-dental procedures, poses significant management challenges. The prevalent use of systemic treatments, with their frequent substantial side effects, emphasizes the need for alternative therapeutic strategies. Our aim is to explore the efficacy and adherence with a topical drug regimen delivered through a neurosensory stent (NS) for treating chronic neuropathic pain (NP) within the oral cavity.

Trigeminal neuralgia (TN) usually affects the maxillary and mandibular branches of the fifth cranial nerve. Although the condition is primarily unilateral, few cases of bilateral manifestation have been reported. TN is uncommon; however, it significantly affects patients' quality of life because the neuropathic pain worsens over time.

The aim of the study is to describe the severity, temporal characteristics, and types of autonomic features as they relate to the characteristics of pain of the neuralgias. Also, to describe, based on literature, how these autonomic features can affect the treatment outcomes of patients with craniofacial neuralgias. We carried out a literature search using five databases, PubMed, Embase, OVID, Scopus and Web of Science.

Head pain (HP) and orofacial pain (OFP) are the most prevalent types of pain worldwide, encompassing cranial, oral and facial pain. The aim of this umbrella review was to answer the following questions: "What is the overall prevalence of HP/OFP and the different prevalences of HP/OFP conditions in adults and children?". We searched for studies investigating the prevalence of HP/OFP in four major databases and two databases from the grey literature, based on the following PECOS inclusion criteria: (P)opulation: Adults and children; (E)xposure: Orofacial or head pain conditions such as (1) dental, periodontal and gingival, (2) temporomandibular disorders (TMD), (3) neuropathic conditions, (4) headaches, and (5) idiopathic pain conditions; (C)omparison: None; (O)utcome: Prevalence; (S)tudies: Systematic reviews and/or meta-analyses.
