The quality of subgroup analyses in chronic pain randomized controlled trials: a methodological review
Korean J Pain. 2021 Apr 1;34(2):139-155. doi: 10.3344/kjp.2021.34.2.139.ABSTRACTThe quality of subgroup analyses (SGAs) in chronic non-cancer pain trials is uncertain. The purpose of this study was to address this issue. We conducted a comprehensive search in MEDLINE and EMBASE from January 2012 to September 2018 to identify eligible trials. Two pairs of reviewers assessed the quality of the SGAs and the credibility of subgroup claims using the 10 criteria developed by Sun et al. in 2012.

Transcranial direct current stimulation for spinal cord injury-associated neuropathic pain
Korean J Pain. 2021 Apr 1;34(2):156-164. doi: 10.3344/kjp.2021.34.2.156.ABSTRACTSeveral types of pain occur following spinal cord injury (SCI); however, neuropathic pain (NP) is one of the most intractable. Invasive and non-invasive brain stimulation techniques have been studied in clinical trials to treat chronic NP following SCI. The evidence for invasive stimulation including motor cortex and deep brain stimulation via the use of implanted electrodes to reduce SCI-related NP remains limited, due to the small scale of existing studies. The lower risk of complications associated with non-invasive stimulation, including tr...

A novel excisional wound pain model for evaluation of analgesics in rats
Korean J Pain. 2021 Apr 1;34(2):165-175. doi: 10.3344/kjp.2021.34.2.165.ABSTRACTBACKGROUND: Management of pain from open wounds is a growing unmet healthcare need. However, the models available to study pain from wounds or to develop analgesics for the patients suffering from them have primarily relied on incisional models. Here, we present the first characterized and validated model of open wound pain.METHODS: Unilateral full-skin excisional punch biopsy wounds on rat hind paws were evaluated for evoked pain using withdrawal responses to mechanical and thermal stimulation, and spontaneous pain was measured using hind paw ...

Inflammatory cytokines in midbrain periaqueductal gray contribute to diabetic induced pain hypersensitivity through phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin signaling pathway
CONCLUSIONS: Overall, the current study suggests that upregulated proinflammatory cytokines and their receptors in the PAG activate PI3K-mTOR signaling, thereby producing a de-inhibition effect on descending pathways in modulating pain transmission, and eventually contributing to neuropathic pain.PMID:33785669 | DOI:10.3344/kjp.2021.34.2.176 (Source: Korean Journal of Pain)

Effect of pregabalin on nociceptive thresholds and immune responses in a mouse model of incisional pain
Korean J Pain. 2021 Apr 1;34(2):185-192. doi: 10.3344/kjp.2021.34.2.185.ABSTRACTBACKGROUND: It is known that some analgesics as well as pain can affect the immune system. The aim of this study was to investigate the analgesic effect and immunomodulation of pregabalin (PGB) in a mouse incisional pain model.METHODS: A postoperative pain model was induced by hind paw plantar incision in male BALB/c mice. Mice were randomly divided into four groups (n = 8): a saline-treated incision (incision), PGB-treated incision (PGB-incision), sham controls without incision or drug treatment (control), and a PGB-treated control (PGB-contro...

The role of the iliotibial band cross-sectional area as a morphological parameter of the iliotibial band friction syndrome: a retrospective pilot study
Korean J Pain. 2021 Apr 1;34(2):229-233. doi: 10.3344/kjp.2021.34.2.229.ABSTRACTBACKGROUND: Iliotibial band friction syndrome (ITBFS) is a common disorder of the lateral knee. Previous research has reported that the iliotibial band (ITB) thickness (ITBT) is correlated with ITBFS, and ITBT has been considered to be a key morphologic parameter of ITBFS. However, the thickness is different from inflammatory hypertrophy. Thus, we made the ITB cross-sectional area (ITBCSA) a new morphological parameter to assess ITBFS.METHODS: Forty-three patients with ITBFS group and from 43 normal group who underwent T1W magnetic resonance im...

The quality of subgroup analyses in chronic pain randomized controlled trials: a methodological review
Korean J Pain. 2021 Apr 1;34(2):139-155. doi: 10.3344/kjp.2021.34.2.139.ABSTRACTThe quality of subgroup analyses (SGAs) in chronic non-cancer pain trials is uncertain. The purpose of this study was to address this issue. We conducted a comprehensive search in MEDLINE and EMBASE from January 2012 to September 2018 to identify eligible trials. Two pairs of reviewers assessed the quality of the SGAs and the credibility of subgroup claims using the 10 criteria developed by Sun et al. in 2012. The associations between the quality of the SGAs and the studies' characteristics including risk of bias, funding sources, sample size, ...

Transcranial direct current stimulation for spinal cord injury-associated neuropathic pain
Korean J Pain. 2021 Apr 1;34(2):156-164. doi: 10.3344/kjp.2021.34.2.156.ABSTRACTSeveral types of pain occur following spinal cord injury (SCI); however, neuropathic pain (NP) is one of the most intractable. Invasive and non-invasive brain stimulation techniques have been studied in clinical trials to treat chronic NP following SCI. The evidence for invasive stimulation including motor cortex and deep brain stimulation via the use of implanted electrodes to reduce SCI-related NP remains limited, due to the small scale of existing studies. The lower risk of complications associated with non-invasive stimulation, including tr...

A novel excisional wound pain model for evaluation of analgesics in rats
Korean J Pain. 2021 Apr 1;34(2):165-175. doi: 10.3344/kjp.2021.34.2.165.ABSTRACTBACKGROUND: Management of pain from open wounds is a growing unmet healthcare need. However, the models available to study pain from wounds or to develop analgesics for the patients suffering from them have primarily relied on incisional models. Here, we present the first characterized and validated model of open wound pain.METHODS: Unilateral full-skin excisional punch biopsy wounds on rat hind paws were evaluated for evoked pain using withdrawal responses to mechanical and thermal stimulation, and spontaneous pain was measured using hind paw ...

Inflammatory cytokines in midbrain periaqueductal gray contribute to diabetic induced pain hypersensitivity through phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin signaling pathway
CONCLUSIONS: Overall, the current study suggests that upregulated proinflammatory cytokines and their receptors in the PAG activate PI3K-mTOR signaling, thereby producing a de-inhibition effect on descending pathways in modulating pain transmission, and eventually contributing to neuropathic pain.PMID:33785669 | DOI:10.3344/kjp.2021.34.2.176 (Source: Korean Journal of Pain)

Effect of pregabalin on nociceptive thresholds and immune responses in a mouse model of incisional pain
Korean J Pain. 2021 Apr 1;34(2):185-192. doi: 10.3344/kjp.2021.34.2.185.ABSTRACTBACKGROUND: It is known that some analgesics as well as pain can affect the immune system. The aim of this study was to investigate the analgesic effect and immunomodulation of pregabalin (PGB) in a mouse incisional pain model.METHODS: A postoperative pain model was induced by hind paw plantar incision in male BALB/c mice. Mice were randomly divided into four groups (n = 8): a saline-treated incision (incision), PGB-treated incision (PGB-incision), sham controls without incision or drug treatment (control), and a PGB-treated control (PGB-contro...

The role of the iliotibial band cross-sectional area as a morphological parameter of the iliotibial band friction syndrome: a retrospective pilot study
Korean J Pain. 2021 Apr 1;34(2):229-233. doi: 10.3344/kjp.2021.34.2.229.ABSTRACTBACKGROUND: Iliotibial band friction syndrome (ITBFS) is a common disorder of the lateral knee. Previous research has reported that the iliotibial band (ITB) thickness (ITBT) is correlated with ITBFS, and ITBT has been considered to be a key morphologic parameter of ITBFS. However, the thickness is different from inflammatory hypertrophy. Thus, we made the ITB cross-sectional area (ITBCSA) a new morphological parameter to assess ITBFS.METHODS: Forty-three patients with ITBFS group and from 43 normal group who underwent T1W magnetic resonance im...
