RESUMEN

Objective: This study aims to assess the impact of a humanistic care-based nursing model on the psychological well-being of individuals diagnosed with primary trigeminal neuralgia (TN) and attending a pain clinic. Methods: A prospective cohort study was conducted, including 166 patients diagnosed with primary trigeminal neuralgia who sought treatment at our hospital's Pain Clinic between March 2022 and December 2022. Among them, 88 patients receiving care based on a humanistic care-based nursing model constituted the observation group, while 78 patients receiving standard nursing care comprised the control group. The Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were employed to evaluate patients' psychological states. Additionally, changes in systolic and diastolic blood pressure, along with nursing satisfaction levels, were recorded. A three-month follow-up was conducted, during which the recovery quality was assessed using the Questions of Reality-155 (QOR-15). Results: Following the nursing intervention, the observation group displayed lower SAS/SDS scores and reduced diastolic and systolic blood pressure compared to the control group (P < .05). Moreover, nursing satisfaction in the observation group was significantly higher than in the control group (P < .05). The follow-up results demonstrated that the recovery quality of the observation group was higher compared to the control group (P < .05). Conclusions: Implementing a humanistic care-based nursing model effectively enhances the psychological well-being and recovery quality of trigeminal neuralgia outpatients attending pain clinics.

RESUMEN

BACKGROUND: It is frequently reported that neuropathic pain is associated with abnormalities in brain function and structure as well as cognitive deficits. However, the contributing mechanisms have remained elusive. OBJECTIVES: We aimed to investigate the systemic ultrastructural changes of the peripheral nervous system (PNS) and central nervous system (CNS) in rats with trigeminal neuralgia (TN) induced by cobra venom, as well as the effects and mechanisms of electroacupuncture (EA) and pregabalin (PGB) on TN. STUDY DESIGN: This study used an experimental design in rats. SETTING: The research took place in the laboratory at the Aviation General Hospital of China Medical University and Beijing Institute of Translational Medicine. METHODS: Male Sprague-Dawley rats were randomly divided into 4 groups (n = 12/group): cobra venom (CV), PGB, EA, and sham-operated (SHAM). The development of pain-related behaviors and spatial learning and memory abilities were measured using video recordings and Morris water maze tests, respectively. The ultrastructural changes of the PNS and CNS were examined using transmission electron microscopy. We also screened the differentially expressed genes and proteins in the prefrontal cortex  and hippocampus using  ribonucleic acid sequencing and isobaric tag for relative and absolute quantitation techniques, respectively. Data for the behavioral tests and molecular biology were analyzed with a one-way analysis of variance. RESULTS: The rats in the CV group exhibited long-lasting pain-like behaviors, cognitive deficits, and systemic ultrastructural changes. Both EA and PGB alleviated the chronic pain syndrome, but EA also inhibited the chronic pain-induced cognitive dysfunction and restored normal cellular structures, while PGB was associated with no improvements. Transcriptomic and proteomic analyses revealed marcks, pak2 and acat1 were altered in rats with TN but were adjusted back to baseline by EA but not by PGB. LIMITATIONS: We examined systemic ultrastructural alterations at different levels of the nervous system; however, the detailed timeline of the damage process was not explicitly delineated.  Moreover, the current study provides only preliminary evidence for the neurobiological mechanisms of cognitive impairment resulting from chronic pain.  Further research is still necessary (using models such as gene knockout rats and cell cultures) before a detailed mechanism can be postulated. CONCLUSIONS: EA treatment may offer significant advantages when compared to PGB for the treatment of cognitive impairment associated with chronic pain. Moreover, marcks, pak2 and acat1 may be the potential therapeutic targets of EA.

RESUMEN

Depression symptoms are often found in patients suffering from chronic pain, a phenomenon that is yet to be understood mechanistically. Here, we systematically investigate the cellular mechanisms and circuits underlying the chronic-pain-induced depression behavior. We show that the development of chronic pain is accompanied by depressive-like behaviors in a mouse model of trigeminal neuralgia. In parallel, we observe increased activity of the dopaminergic (DA) neuron in the midbrain ventral tegmental area (VTA), and inhibition of this elevated VTA DA neuron activity reverses the behavioral manifestations of depression. Further studies establish a pathway of glutamatergic projections from the spinal trigeminal subnucleus caudalis (Sp5C) to the lateral parabrachial nucleus (LPBN) and then to the VTA. These glutamatergic projections form a direct circuit that controls the development of the depression-like behavior under the state of the chronic neuropathic pain.

RESUMEN

OBJECTIVE: To analyze the psychological status in patients with trigeminal neuralgia before surgery and in the early postoperative period after microvascular decompression of the trigeminal nerve. METHODS: Psychological features of personality were studied in 56 patients aged from 28 to 80 years with trigeminal neuralgia. To study the psychological status, such scales as Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale and Patient's Subjective Assessment of Treatment Effectiveness Scale (PSATES) were used with special attention paid to presence of suicidal thoughts. RESULTS: The signs of anxiety were clinically significant in 7%, absent - in 66 % of the patients. There were no signs of depression in 63 % of cases, while 7% of the patients suffered from clinically significant depression. Pain catastrophizing was observed in 76.8 % of patients. None of the patients rated the intervention as "excellent" on PSATES despite the complete pain relief in the majority of patients (78.6 %), and only 16.1 % of the patients rated it as "good". The aggravation factor had a significant influence on this evaluation (p = 0.01). CONCLUSIONS: General psychological status assessment can be used to objectify the indicators of the questionnaires and pain scales, as well as to determine the treatment tactics in this group, especially when it is necessary to clarify indications for an intervention and to decide on its proper time. Regardless of the outcome, the patients need time and psychological help for social adaptation due to changes in their social status.

RESUMEN

BACKGROUND: Neuropathic facial pain occurs due to pathologic dysfunctions of a nerve responsible for mediating sensory fibers to the head. Surgical interventions, in cases of failed medical therapy, include microvascular decompression, radiofrequency (RF) ablation, percutaneous balloon decompression, and stereotactic radiosurgery. In this review, we focused on RF ablation as a treatment for chronic facial pain. OBJECTIVES: The objective of this review was to summarize available evidence behind RF ablation for facial pain, including pain outcome measures, secondary outcomes, and complications. STUDY DESIGN: Systematic review. SETTING: This systematic review examined studies that applied the use of RF ablation for management of facial pain. METHODS: This systematic review was reported following the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two reviewers independently scored the methodological quality of the selected studies. Due to heterogeneity of studies, a best-evidence synthesis of the available prognostic factors was provided. RESULTS: We reviewed 44 studies and assessed their short- and long-term pain relief measurements, as well as secondary outcomes including patient satisfaction, quality of life improvements, decrease in oral medication use, and recurrence rates. Maximal pain relief was achieved in treatment groups using combined continuous radiofrequency (CRF) and pulsed radiofrequency (PRF) therapies, followed by CRF therapy alone and finally PRF therapy alone. All treatment regimens improved secondary outcomes. Common complications of treatment included facial numbness, masseter weakness, cheek hematomas, diminished corneal reflex, and dry eyes. LIMITATIONS: A large variability in definitions of trigeminal neuralgia, RF technique, and patient selection bias was observed in our selected cohort of studies. In addition, there was a paucity of strong longitudinal randomized controlled trials and prospective studies. CONCLUSIONS: This systematic review found evidence that RF ablation is efficient in treating patients with facial pain, as well as in improving quality of life and reducing oral medication use. Maximal pain control is achieved using combined CRF and PRF therapy. Complications are uncommon and include facial numbness, masseter weakness, cheek hematomas, diminished corneal reflex, and dry eyes.

RESUMEN

BACKGROUND: Trigeminal neuralgia (TN) is an orofacial condition defined by reoccurring, spontaneous, short-lived but excruciating stabbing pain. Pharmacological interventions constitute the first-line treatment for TN, with antiepileptic drugs commonly prescribed. People treated for TN pain with antiepileptic drugs describe cognitive and motor difficulties affecting activities of daily living, and report poorer quality of life. We undertook the first comprehensive objective evaluation of sensorimotor and cognitive performance in participants being treated for TN pain with antiepileptic drugs relative to age-matched controls. METHODS: Participants (43 TN, 41 control) completed a battery of sensorimotor (steering, aiming and tracking) and cognitive (working memory, processing speed, inhibition) tasks. RESULTS: The TN group performed significantly worse than controls on the sensorimotor tracking and aiming tasks and across all cognitive measures. CONCLUSIONS: The data explain why patients treated with antiepileptic drugs report impairment when conducting activities of daily living (given the need for cognitive and motor capability within most of these). The study is an important first step in: (i) ensuring there is adequate information on the impact of pharmacological treatment; (ii) identifying measures to determine optimal medication dosage and track change over time; (iii) creating an evidence base that could allow scientific justification of alternative pain treatment options for TN (e.g. the costs/benefits of surgery).

RESUMEN

Trigeminal neuralgia (TN) is debilitating and is usually accompanied by mood disorders. The lateral habenula (LHb) is considered to be involved in the modulation of pain and mood disorders, and the present study aimed to determine if and how the LHb participates in the development of pain and anxiety in TN. To address this issue, a mouse model of partial transection of the infraorbital nerve (pT-ION) was established. pT-ION induced stable and long-lasting primary and secondary orofacial allodynia and anxiety-like behaviors that correlated with the increased excitability of LHb neurons. Adeno-associated virus (AAV)-mediated expression of hM4D(Gi) in glutamatergic neurons of the unilateral LHb followed by clozapine-N-oxide application relieved pT-ION-induced anxiety-like behaviors but not allodynia. Immunofluorescence validated the successful infection of AAV in the LHb, and microarray analysis showed changes in gene expression in the LHb of mice showing allodynia and anxiety-like behaviors after pT-ION. Among these differentially expressed genes was Tacr3, the downregulation of which was validated by RT-qPCR. Rescuing the downregulation of Tacr3 by AAV-mediated Tacr3 overexpression in the unilateral LHb significantly reversed pT-ION-induced anxiety-like behaviors but not allodynia. Whole-cell patch clamp recording showed that Tacr3 overexpression suppressed nerve injury-induced hyperexcitation of LHb neurons, and western blotting showed that the pT-ION-induced upregulation of p-CaMKII was reversed by AAV-mediated Tacr3 overexpression or chemicogenetic inhibition of glutamatergic neurons in the LHb. Moreover, not only anxiety-like behaviors, but also allodynia after pT-ION were significantly alleviated by chemicogenetic inhibition of bilateral LHb neurons or by bilateral Tacr3 overexpression in the LHb. In conclusion, Tacr3 in the LHb plays a protective role in treating trigeminal nerve injury-induced allodynia and anxiety-like behaviors by suppressing the hyperexcitability of LHb neurons. These findings provide a rationale for suppressing unilateral or bilateral LHb activity by targeting Tacr3 in treating the anxiety and pain associated with TN.

RESUMEN

Emotional disorders are common comorbid conditions that further exacerbate the severity and chronicity of chronic pain. However, individuals show considerable vulnerability to the development of chronic pain under similar pain conditions. In this study on male rat and mouse models of chronic neuropathic pain, we identify the histone deacetylase Sirtuin 1 (SIRT1) in central amygdala as a key epigenetic regulator that controls the development of comorbid emotional disorders underlying the individual vulnerability to chronic pain. We found that animals that were vulnerable to developing behaviors of anxiety and depression under the pain condition displayed reduced SIRT1 protein levels in central amygdala, but not those animals resistant to the emotional disorders. Viral overexpression of local SIRT1 reversed this vulnerability, but viral knockdown of local SIRT1 mimicked the pain effect, eliciting the pain vulnerability in pain-free animals. The SIRT1 action was associated with CaMKIIα downregulation and deacetylation of histone H3 lysine 9 at the CaMKIIα promoter. These results suggest that, by transcriptional repression of CaMKIIα in central amygdala, SIRT1 functions to guard against the emotional pain vulnerability under chronic pain conditions. This study indicates that SIRT1 may serve as a potential therapeutic molecule for individualized treatment of chronic pain with vulnerable emotional disorders.SIGNIFICANCE STATEMENT Chronic pain is a prevalent neurological disease with no effective treatment at present. Pain patients display considerably variable vulnerability to developing chronic pain, indicating individual-based molecular mechanisms underlying the pain vulnerability, which is hardly addressed in current preclinical research. In this study, we have identified the histone deacetylase Sirtuin 1 (SIRT1) as a key regulator that controls this pain vulnerability. This study reveals that the SIRT1-CaMKIIaα pathway in central amygdala acts as an epigenetic mechanism that guards against the development of comorbid emotional disorders under chronic pain, and that its dysfunction causes increased vulnerability to the development of chronic pain. These findings suggest that SIRT1 activators may be used in a novel therapeutic approach for individual-based treatment of chronic pain.

RESUMEN

P2Y purinergic receptors expressed in neurons and satellite glial cells (SGCs) of the trigeminal ganglion (TG) contribute to inflammatory and neuropathic pain. P2Y14 receptor expression is reported in the spinal cord, dorsal root ganglion (DRG), and TG. In present study, the role of P2Y14 receptor in the TG in inflammatory orofacial pain of Sprague-Dawley (SD) rats was investigated. Peripheral injection of complete Freund's adjuvant (CFA) induced mechanical hyperalgesia with the rapid upregulation of P2Y14 receptor, glial fibrillary acidic protein (GFAP), interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α), C-C chemokine CCL2, phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2), and phosphorylated p38 (p-p38) proteins in the TG. Furthermore, immunofluorescence staining confirmed the CFA-induced upregulation of P2Y14 receptor. Double immunostaining showed that P2Y14 receptor colocalized with glutamine synthetase (GS) and neuronal nuclei (NeuN). Finally, trigeminal injection of a selective antagonist (PPTN) of P2Y14 receptor attenuated CFA-induced mechanical hyperalgesia. PPTN also decreased the upregulation of the GFAP, IL-1ß, TNF-α, CCL2, p-ERK1/2, and p-p38 proteins. Our findings showed that P2Y14 receptor in TG may contribute to orofacial inflammatory pain via regulating SGCs activation, releasing cytokines (IL-1ß, TNF-α, and CCL2), and phosphorylating ERK1/2 and p38.

RESUMEN

OBJECTIVE: Trigeminal neuralgia (TN) is a common cranial nerve disease. Meanwhile, it is suggested in some studies that orofacial pain can also lead to some psychological diseases. Therefore, the current study was carried out aiming to explore the relationship between depression as well as anxiety and TN; at the same time, the effect on the postoperative outcome of microvascular decompression (MVD) would also be explored. METHODS: The Hamilton Depression Rating Scale (HDRS) scores, as well as the Hamilton Anxiety Rating Scale (HARS) scores in TN cases were compared with those among patients without TN. Multiple logistic regression models were also used to assess the associations of HDRS and HARS scores with TN. Patients were divided into 2 groups according to the MVD outcome in TN patients, and the HDRS and HARS scores were between pain-free patients and those who still suffered from pain. RESULTS: The HDRS and HARS scores in TN patients were evidently increased relative to those observed in normal individuals. HDRS and HARS scores were found to be positively associated with the Visual Analog Scale pain score and onset duration in TN patients. Additionally, remarkably higher HDRS and HARS scores were observed in the persistent pain group than in pain-free group. CONCLUSIONS: The findings of this study reveal that depression and anxiety are closely associated with the incidence of TN, which may also affect the outcome of patients undergoing MVD.

RESUMEN

The object of this study was to reveal the occurrence, risk factors and prognosis of posttraumatic stress disorder (PTSD) in patients with trigeminal neuralgia (TN). Adult patients who were diagnosed with TN were prospectively collected from our neuroscience center. Among the 103 patients recruited, thirty (29.1%) participants were identified as probable PTSD cases measured with PTSD Checklist for DSM-5 (PCL-5). Compared with patients without PTSD, patients with probable PTSD were more likely to be female, have severe pain intensity, be with severely interfered general activities, be with more intense depression and anxiety, and be more habitually using maladaptive coping strategies. Logistic regression analysis showed female sex, severe pain intensity, anxiety and depression predicted probable PTSD. In the 28 patients who were initially identified as probable PTSD and had 6-month follow-up data, 21 reported complete pain relief and 4 reported partial pain relief. Fifteen of the patients who experienced complete pain relief recovered from probable PTSD. Our work indicated that PTSD can develop among patients with TN. Complete pain relief through surgical treatments can help most patients with probable PTSD recover, however, psychological support is advised for those who are still obsessed by mental disorders even after pain relief.

RESUMEN

Trigeminal neuralgia (TN) is characterized by sharp, electric shock-like pain, which can be triggered by trivial stimuli. Although medical and surgical treatments are available for TN, some patients experience refractory pain, which has a significant impact on their quality of life. The aim of this systematic review was to determine the psychosocial impact of orofacial pain in patients with diagnosed TN. A search was initiated in three electronic databases (Embase, MEDLINE, PubMed) to identify potential studies for inclusion in the review. All types of study published in English that reported psychosocial measures using validated psychometric questionnaires were included. A total of 585 articles were retrieved from the search. These were screened thoroughly, leading to the selection of 13 articles for data extraction and final analysis. The results show the chronic overwhelming nature of TN, with pain levels varying from mild to severe. Psychometric scores indicated mild to moderate depression, moderate to severe anxiety, and moderate to severe functional limitation of daily life activities in TN patients. Therefore, psychological support within a multidisciplinary team is recommended for TN patients to help them cope better with their chronic disorder and to improve the efficacy of treatment.

RESUMEN

BACKGROUND: Side effects of anti-epileptic drugs (AEDs) have not been adequately documented in trigeminal neuralgia and its variants. The aim of this observational cross-sectional study was to compare the A-B Neuropsychological Assessment Schedule (ABNAS), which measures cognitive side effects to the Adverse Events Profile (AEP), which looks at a broader range of side effects, and to investigate drug/dosage relationships with questionnaire scores to help determine a point at which a drug change would be indicated. METHODS: One hundred five patients were recruited from a facial pain clinic, over a 10-month period. Self-complete questionnaire scores were compared between patients using different AEDs. RESULTS: A-B Neuropsychological Assessment Schedule score correlated well with AEP indicating that cognitive side effects were a significant burden. Toxic range on the ABNAS was estimated to occur when scores were >43/72 (95% CI: 37.4-48.6). Polytherapy is weakly associated with the higher scores. Oxcarbazepine dosage was found to linearly correlate with AEP and ABNAS scores, better than carbamazepine dosage. Memory alteration was least common with lamotrigine and oxcarbazepine, and there was less association between fatigues with oxcarbazepine/pregabalin. CONCLUSION: Anti-epileptic drugs have significant side effects. The ABNAS questionnaire is a useful tool along with the AEP to recognize and monitor AEDs' side effects and to help to adjust medications to optimal dosage.

RESUMEN

OBJECTIVE: To assess effectiveness of Gamma Knife Radiosurgery (GKRS) in improving quality of life (QoL) in patients with idiopathic trigeminal neuralgia (TN). METHODS: Between January 2001 and October 2013, 166 patients with medically resistant TN were treated at our institution with GKRS. Patients were divided into 2 groups: patients with typical TN (TTN) and patients with atypical TN (ATN). All patients underwent clinical evaluation using Marseille and Barrow Neurological Institute pain and numbness scales; in addition, they completed the Short-Form 36 Health Survey, Activities of Daily Living, and Excellent Good Fair Poor questionnaires and underwent psychological and neurologic examination. RESULTS: Mean follow-up time was 64.7 months. All Short-Form 36 domains were significantly improved in both groups after treatment, with an evident trend to reach the median values of healthy Italian population. Mean postoperative Activities of Daily Living score in the TTN group and ATN group were 5.8 and 5.4, respectively, and Karnofsky Performance Status increased to 94.2 and 86.4, respectively. Pain recurrence negatively affected patients' QoL and psychofunctional performance without reaching statistical significance. At the last follow-up, 73% of patients were clustered in the pain-relief group. CONCLUSIONS: GKRS significantly improves QoL and functional and psychosocial performance of patients with idiopathic trigeminal neuralgia. A trend was observed toward a more favorable outcome in patients with TTN, compared with patients with ATN, without reaching a statistically significant distinction.

RESUMEN

AIMS: To describe the clinical characteristics of trigeminal neuralgia (TN) in a multi-ethnic Malaysian population and to relate them to standardized measures of pain severity, anxiety, depression, and quality of life (QoL). METHODS: Patients fulfilling the International Headache Society (IHS) criteria for TN were prospectively interviewed for their demographic and clinical data. Pain intensity was rated with a visual analog scale (VAS), anxiety and depression were determined by the Hospital Anxiety and Depression Scale (HADS), and QoL was assessed by the Short-Form 36 (SF-36) questionnaire. Chi-square, Mann-Whitney U, and Spearman correlation tests were used to test for differences considering a significance level of P < .05. RESULTS: Of the 75 included patients, 52 (69.3%) were women with a mean ± standard deviation (SD) onset age of 52.0 ± 12.7 years, and 57.3% were Chinese, 24.0% Malay, and 18.7% Indian. Pain was more common on the right side (69.3%) and in the maxillary and mandibular divisions. VAS scores for pain at its worst were higher in anxious/borderline anxious patients compared to non-anxious patients (89.5 ± 15.9 vs 80.9 ± 17.2, respectively; P < .05), and VAS scores for pain at its least were higher in depressed/borderline depressed subjects compared to non-depressed subjects (38.4 ± 25.8 vs 23.0 ± 19.2, respectively; P < .05). Chinese patients had lower VAS scores for pain at its least compared to Indian patients (19.7 ± 16.1 vs 39.9 ± 24.7; P < .01). TN patients scored lower in all eight domains of the SF-36 compared to the general population. Indian patients had lower scores in role limitations due to physical health (8.9 ± 23.2 vs 49.4 ± 43.8; P < .01) and social function (56.3 ± 13.6 vs 76.5 ± 23.6; P < .01) than Chinese patients, and Malay patients had lower mental health scores compared to Chinese patients (59.1 ± 19.5 vs 73.0 ± 21.0; P < .01). CONCLUSION: Clinical characteristics of TN patients were similar to those of other populations. There were differences in pain ratings and QoL between TN patients of different ethnicities, as well as between those with anxiety and depression.

RESUMEN

AIMS: To investigate the effects and interactions of sex and stress (provoked by chronic restraint [RS]) on pain-like behavior in a rat model of trigeminal neuropathic pain. METHODS: The effects of sex and RS (carried out for 14 days as a model for stress) on somatosensory measures (reaction to pinprick, von Frey threshold) in a rat model of trigeminal neuropathic pain were examined. The study design was 2 × 4, with surgery (pain) and sham surgery (no pain) interacting with male restrained (RS) and unrestrained (nRS) rats and female RS and nRS rats. A total of 64 Sprague Dawley rats (32 males and 32 females) were used. Half of the animals in each sex group underwent RS, and the remaining half were left unstressed. Following the RS period, trigeminal neuropathic pain was induced by unilateral infraorbital nerve chronic constriction injury (IOCCI). Half of the animals in the RS group and half in the nRS group (both males and females) were exposed to IOCCI, and the remaining halves to sham surgery. Elevated plus maze (EPM) assessment and plasma interferon gamma (IFN-γ) levels were used to measure the effects of RS. Analysis of variance (ANOVA) was used to assess the effects of stress, sex, and their interactions on plasma IFN-γ levels, changes in body weight, EPM parameters, tactile allodynia, and mechanohyperalgesia. Pairwise comparisons were performed by using Tukey post hoc test corrected for multiple comparisons. RESULTS: Both male and female RS rats showed significantly altered exploratory behavior (as measured by EPM) and had significantly lower plasma IFN-γ levels than nRS rats. Rats exposed to RS gained weight significantly slower than the nRS rats, irrespective of sex. Following RS but before surgery, RS rats showed significant bilateral reductions in von Frey thresholds and significantly increased pinprick response difference scores compared to nRS rats, irrespective of sex. From 17 days postsurgery, RSIOCCI rats showed significantly reduced von Frey thresholds and significantly increased pinprick response difference scores compared to nRS-IOCCI rats, and the von Frey thresholds were significantly lower in females than in males. RS-sham females-but not RS-sham males-developed persistently reduced thresholds and increased pinprick response difference scores. CONCLUSION: RS produced an increased bilateral sensitivity to stimuli applied to the vibrissal pad following infraorbital nerve injury, irrespective of sex. This observed sensitivity subsequently persisted in RS-sham female rats but not in RS-sham male rats. Stress induced a significant but moderate increase in pain-like behavior in female rats compared to male rats. RS had no significant sex effects on IFN-γ levels, EPM parameters, or body weight gain. This suggests that stress may have a selective effect on pain-like behavior in both sexes, but the possible mechanisms are unclear.
