Molecular targets in bone cancer pain: a systematic review of inflammatory cytokines.

Bone cancer pain (BCP) profoundly impacts patient's quality of life, demanding more effective pain management strategies. The aim of this systematic review was to investigate the role of inflammatory cytokines as potential molecular targets in BCP. A systematic search for animal rodent models of bone cancer pain studies was conducted in PubMed, Scopus, and Web of Science. Methodological quality and risk of bias were assessed using the SYRCLE RoB tool. Twenty-five articles met the inclusion criteria, comprising animal studies investigating molecular targets related to inflammatory cytokines in BCP. A low to moderate risk of bias was reported. Key findings in 23 manuscripts revealed upregulated classic pro-inflammatory cytokines (TNF-α, IL-1ß, IL-6, IL-17, IL-18, IL-33) and chemokines in the spinal cord, periaqueductal gray, and dorsal root ganglia. Interventions targeting these cytokines consistently mitigated pain behaviors. Additionally, it was demonstrated that glial cells, due to their involvement in the release of inflammatory cytokines, emerged as significant contributors to BCP. This systematic review underscores the significance of inflammatory cytokines as potential molecular targets for alleviating BCP. It emphasizes the promise of targeted interventions and advocates for further research to translate these findings into effective therapeutic strategies. Ultimately, this approach holds the potential to enhance the patient's quality of life.

Effects of different analgesic methods of hydromorphone on analgesic efficacy and sleep quality in patients with refractory cancer pain / 中国基层医药

Objective:To investigate the effects of different analgesic methods of hydromorphone on analgesic efficacy and sleep quality in patients with refractory cancer pain.Methods:Sixty patients with refractory cancer pain who received three-step analgesic treatment in Quzhou People's Hospital from August 2018 to December 2019 and acquired poor analgesic effects were included in this study. They were randomly assigned to undergo either an intravenous patient-controlled analgesia with hydromorphone (HV group, n = 30) or an intrathecal patient-controlled analgesia with hydromorphone (HI group, n = 30) for 10 consecutive days. The analgesic efficacy in each group was evaluated using the numerical rating scale (NRS) before and 2, 4, 24, 48 hours, and 10 days after administration. The frequency of breakthrough pain (BTP) at each time point was recorded. The sedation effect of medication was evaluated using the Ramsay score. The sleep quality of patients was evaluated using the Pittsburgh sleep quality index (PSQI). The activities of CD 3+, CD 4+, and CD 4+/CD 8+ lymphocyte subsets were measured by flow cytometry at different time points. The adverse reactions within 10 days after treatment were observed and recorded. Results:Before and at each time point after treatment, there were no significant differences in NRS score, the frequency of BTP, Ramsay score, and PSQI score between the two groups (NRS score: t = 0.45, 0.91, 0.52, 1.19, 0.97, 1.92, all P > 0.05; frequency of BTP: t = 0.34, 1.88, 0.86, 1.71, 1.22, 0.76, all P > 0.05; Ramsay score: t = 0.56, 0.46, 0.63, 0.22, 0.99, 0.14, all P > 0.05; PSQI: t = 0.86, 1.25, 1.46, 1.05, 0.57, 1.93, all P > 0.05). At each time point after treatment, the activities of CD 3+, CD 4+, and CD 4+/CD 8+ cells increased in each group, and the activities of CD 3+, CD 4+, and CD 4+/CD 8+ cells in the HI group were significantly higher than those in the HV group (CD 3+: t = 3.72, 3.12, 2.85, 3.13, 2.44, all P < 0.05; CD 4+: t = 3.62, 2.45, 3.31, 3.19, 2.70; all P > 0.05; CD 4+/CD 8+: t = 3.10, 2.74, 2.83, 3.24, 3.41, all P < 0.05). The total incidence of adverse reactions was slightly, but not significantly, lower in the HI group than the HV group [14.00% (7/30) vs. 26.00% (13/30), χ2 = 2.70, P = 0.100]. Conclusion:Compared with intravenous administration of hydromorphone, intrathecal administration of hydromorphone can better effectively relieve pain, decrease the frequency of BTP, improve sleep quality, has a good sedative effect, improve immune function, and has fewer adverse reactions.

Sevoflurane topical analgesia for intractable pain with suicidal ideation.

Proper symptom management to improve quality of dying is mandatory in palliative care patients. Home-based control of pain caused by leg ulcers is challenging, especially when the pain is severe and refractory to conventional analgesics, the patient is intolerant to opioids and refuses invasive measures. This was the case for an 87-year-old woman under oncological palliative care who suffered from a leg ulcer causing refractory pain, which produced suicidal ideation. Leg amputation was indicated, but she had signed a living will refusing any invasive measures. After obtaining written informed consent, sevoflurane was applied topically on the ulcer, which resulted in a rapid and long-lasting reduction of pain. Daily self-administration of sevoflurane successfully controlled the wound pain and the patient abandoned her suicidal ideation, the wound healed 35 days later, and her quality of dying improved remarkably. Topical sevoflurane deserves further research on ulcers of vascular and also neoplastic aetiology.

Intravenous patient-controlled analgesia hydromorphone combined with pregabalin for the treatment of postherpetic neuralgia: a multicenter, randomized controlled study.

BACKGROUND: Postherpetic neuralgia (PHN) is the most common complication of acute herpes zoster. The treatment of PHN remains a challenge for clinical pain management. Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders. In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. METHODS: Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. RESULTS: Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment. After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group. The most common adverse reactions in the hydromorphone group were dizziness and nausea, with no significant respiratory depression. CONCLUSIONS: IV PCA hydromorphone combined with oral pregabalin provides superior pain relief in patients with PHN, which is worthy of clinical application and promotion.

Treatment of radiation-induced brachial plexopathy with omentoplasty.

Radiation-induced brachial plexus neuropathy (RIBPN) is a rare and delayed non-traumatic injury to the brachial plexus, which occurs following radiation therapy to the chest wall, neck, and/or axilla in previously treated patients with cancer. The incidence of RIBPN is more common in patients treated for carcinoma of the breast and Hodgkin lymphoma. With the improvement in radiation techniques, the incidence of injury to the brachial plexus following radiotherapy has dramatically reduced. The currently reported incidence is 1.2% in women irradiated for breast cancer. The progression of symptoms is gradual in about two-thirds of cases; the patients may initially present with paresthesia followed by pain, and later progress to motor weakness in the affected limb. We present the case of a 68-year-old female patient with breast cancer submitted to surgery, chemotherapy, and radiotherapy in the year 2000. Eighteen years later, she developed symptoms and signs compatible with RIBPN and was successfully submitted to omentoplasty for pain control. Omentoplasty is an alternative treatment for RIBPN refractory to conservative treatment, which seems to be effective in improving neuropathic pain. However, postoperative worsening of the motor strength is a real possibility, and all candidates for this type of surgery must be informed about the risk of this complication.

Interventional Pain Management for Cancer Pain: An Analysis of Outcomes and Predictors of Clinical Response.

BACKGROUND: Interventional procedures are offered routinely to patients seen in McGill University's interdisciplinary cancer pain management program. However, publications on these procedures are scarce, making it difficult to predict which patients may benefit from them. OBJECTIVES: We hypothesized that interventional pain procedures offered to cancer patients could provide relief of pain as well as other symptoms. Furthermore, some variables may predict the efficacy of such procedures. STUDY DESIGN: We conducted a retrospective chart review of interventional pain management procedures. SETTING: The procedures reviewed were conducted at the Cancer Pain Program and performed at the interventional suites of the McGill University Health Centre. METHODS: The retrospective chart review included interventional pain management procedures performed between June 2015 and March 2017. Demographic data, details about the underlying cancer and about the procedure and peripTrocedural patients' reported outcomes were recorded for analysis. RESULTS: Eighty-two of 126 procedures were included for analysis. Most patients presented with metastatic disease (75%). Eighty percent of the patients reported pain relief, with the average pain severity decreasing by more than 2 points on a 0-to-10 Numeric Rating Scale for pain (from 6.5 of 10 to 4.2 of 10). Forty-three percent of patients were considered responders (>= 50% pain relief). Responders also reported a significant decrease in fatigue, depression, anxiety, drowsiness, and improved well-being. Among responders, average daily opioid use decreased significantly, by 60% on average. None of the analyzed variables correlated with the response; however, psychosocial variables like anxiety and depression showed a nonsignificant trend towards predicting procedure failure. LIMITATIONS: The core limitations of this study are its size and retrospective nature. CONCLUSIONS: In this cohort of cancer pain patients, interventional cancer pain procedures provided effective pain relief and other benefits, including pain relief, reduced burden of symptoms, and reduction of opioid intake, while demonstrating a favorable safety profile. Patients with poorer ratings of depression and fatigue derived less benefit from procedures, suggesting that offering such procedures as part of patients' treatment plan would be sensible, rather than leaving interventions for later stages.

Hypnosis for refractory severe neuropathic pain: A case study.

Chronic pain not only has the greatest negative effect on quality of life compared with other chronic health problems but also contributes to the greatest disability worldwide. Management of chronic neuropathic pain is particularly challenging given its association with other pain processes, the fact that less than half of patients respond to a single pain medication, and the lack of evidence regarding combination therapy (i.e. a treatment regimen that combines several scheduled pain medications) safety and efficacy. Given these challenges, there is a growing interest in the application of complementary and alternative medicine (CAM) therapies such as yoga, acupuncture, and hypnosis. We present the case of a 67-year-old male with severe diabetic neuropathy refractory to first, second, and third-line treatments. His disabling pain precipitated premature retirement, contributing to severe depression with suicidality requiring hospitalization. Ultimately, he experienced relief through an integrative health regimen, and he identified hypnosis as the most effective therapy for his pain. Through individual and group sessions, recordings, and daily self-hypnosis, he improved both his chronic pain symptomatology and quality of life, simultaneously decreasing opioid use. Simulation modeling analysis of his pain ratings over time showed that they reliably decreased after engaging in hypnosis, r = -.33, p =.001. A growing body of research suggests that hypnosis is beneficial as part of an integrative treatment approach to chronic pain and enhances the efficacy of other therapies. Our medically challenging case study supports that hypnosis may serve as a viable and durable treatment for chronic neuropathic pain.

Clinical observation of Yangxue-Pinggan decoction in the treatment of intractable headache / 国际中医中药杂志

Objective To evaluate the clinical efficacy of Yangxue-Pinggan decoction on intractable headache. Methods A total of 66 patients with intractable headache who met the inclusion criteria were randomly divided into two groups by random number table method, 33 in each group. The control group was given flunarizine hydrochloride capsule orally, while the treatment group was given professor Guan Youbo's Yangxue-Pinggan decoction. Both groups were treated for 4 weeks. The improvement rates of headache were observed. The headache attacks, the degree of headache, the duration of headache and the accompanying symptoms were scored, and the clinical efficacy was evaluated. Results The total effective rate was 97.0％ (32/33) in the treatment group and 63.6％ (21/33) in the control group, which there was significant difference between the two groups (χ2=11.591, P=0.001). After treatment, the scores of the headache attacks, the degree of headache, the duration of headache and the accompanying symptoms in the treatment group were significantly lower than those in the control group (t=17.689, 12.523, 26.907, 25.569, P<0.001). Conclusions The Yangxue-Pinggan decoction can obviously improve the clinical symptoms of intractable headache, relieve the pain degree and reduce the number of attacks, and its clinical efficacy is better than oral flunarizine hydrochloride capsule.

Ultrasound-Guided Percutaneous Cervical and Upper Thoracic Sympathetic Chain Neuromodulation for Upper Extremity Complex Regional Pain Syndrome.

BACKGROUND: Complex regional pain syndrome (CRPS) comprises a group of conditions characterized by severe, debilitating pain that is disproportionate to any inciting event and is not distributed in a specific nerve distribution or dermatome. CASE REPORT: A 42-year-old female with a 2-year history of right upper extremity CRPS type I refractory to conventional management underwent an ultrasound-guided and fluoroscopy confirmed percutaneous peripheral nerve stimulation trial with a lead extending from the C6 to the T3 level to cover the cervical and upper thoracic sympathetic chain. The patient subsequently received a permanent ultrasound-guided lead and implantable pulse generator. At 1-month follow-up, the patient's pain intensity had declined from a weekly average of 8/10 to 1/10 on the verbal pain scale with marked improvement in function. The patient continues to be pain-free or experiences only minimal discomfort 7 years after the implant. She experienced no complications and has discontinued all her pain medications since the implant. CONCLUSION: The placement of a peripheral nerve-stimulating electrode resulted in sustained suppression of intractable pain secondary to CRPS. Ultrasonography guidance enabled the nonsurgical minimally invasive percutaneous approach. Use of ultrasonography may improve the safety of the procedure by permitting direct visualization of the related anatomic structures, thereby reducing the risk of injury to the inferior thyroid artery, vertebral artery, esophagus, intervertebral disc, and pleura.

Clinical research of psychological nursing intervention on the compliance of pain medication in ederly patients with malignant tumor / 中国基层医药

Objective To explore the effect of psychological nursing intervention on the compliance of pain medication in ederly patients with malignant tumor.Methods Retrospective analysis of 92 elderly patients with malignant tumors was conducted.All patients were treated with standardized drugs according to the three-step analgesic principle.The patients were randomly divided into two groups,the control group was given routine nursing intervention,and the observation group was given psychological nursing intervention on the basis of the control group.The improvement of pain response,depression and anxiety,the treatment compliance and nursing satisfaction of two groups before and after treatment were compared.Results The pain relief rate of the observation group was 89.36％,which was significantly higher than 64.44％ of the control group (Z =-3.534,P ＜ 0.05).The total remission rate of the observation group was significantly higher than that of the control group (x2 =4.058,P ＜ 0.05).The depression score of the observation group [(17.52 ± 4.06) points] was significantly lower than (23.35 ± 3.24) points of the control group (t =7.592,P ＜ 0.05).The anxiety score of the observation group [(17.52 ± 4.06) points] was significantly lower than (18.05 ± 4.02) points of the control group (t =7.622,P ＜ 0.05).The compliance of the observation group witb analgesic drugs was better than that of the control group (Z =-6.994,P ＜ 0.05).The nursing satisfaction of the observation group was 87.23％,which was significantly higher than 75.56％ of the control group (Z =-2.764,P ＜ 0.05).Conclusion Psychological nursing intervention can effectively improve the pain response,anxiety and depression of elderly patients with malignant tumor,thus to improve the compliance and safety of the treatment and the care of nursing staff.

Clinical assessment of hydrogen-rich water and oxycodone hydrochloride controlled-release tablets in the treatment of malignant neuropathic pain / 中国医师杂志

Objective To investigate the clinical efficacy of hydrogen-rich water (HRW) combined with oxycodone hydrochloride controlled-release tablets (OHCT) in the treatment of malignant neuropathic pain (MNP) patients.Methods Eighty MNP patients were randomly divided into two groups:OHCT group (group A,n =40) and HRW combined OHCT group (group B,n =40).The visual analog scale (VAS) score,frequency of pain outbreaks,pain relief rate,average dose of OHCT per day,and adverse reactions were observed.Results The VAS scores and frequency of pain outbreaks in groups A and B were significantly reduced after treatment (P ＜0.05).Compared to group A,the VAS scores,pain relief rate,outbreak pain and average dose of OHCT per day in group B were significantly improved after 14 and 28 days of treatment (P ＜ 0.05),and the adverse reactions,such as constipation,nausea and vomiting,in group B were significantly less than those in group A (P ＜ 0.05).Conclusions HRW combined with OHCT can effectively improve the MNP,and reduce average dose of OHCT per day and adverse reactions.

A clínica da dor crônica como ninho de pacientes difíceis: o papel da identificação projetiva / Chronic pain clinic as a haven for difficult patients: the role of projective identification

Pacientes difíceis - ou de personalidade difícil - são frequentemente encontrados na clínica da dor crônica não-oncológica, impondo à relação médico-paciente sobrecargas que vão além das complexidades da doença e do tratamento. Esta revisão/relato de experiência discute o papel que o processo psicológico e comunicacional da identificação projetiva exerce sobre as relações entre pacientes e médicos (e outros profissionais) nas equipes de dor crônica. São revisados os conceitos de identificação projetiva, na sua forma benigna e maligna. Duas vinhetas clínicas são dadas como exemplos de cada uma. São apresentadas situações no cenário da comunicação médico-paciente em que a identificação projetiva opera complicando a relação terapêutica. Ao final, recomendações são dadas sobre o manejo do paciente difícil que se comunica maciçamente por identificação projetiva, assim como às equipes multiprofissionais que lidam com estes pacientes. Os pacientes difíceis de nossa clínica de dor crônica têm em comum o fato de se comunicarem pela forma maligna de identificação projetiva e terem organizações imaturas de personalidade. Nas equipes de dor crônica, as relações entre pacientes e profissionais (assim como as relações entre os profissionais), podem ser otimizadas se a equipe for capaz de identificar precocemente o fenômeno da identificação projetiva e manejá-lo de forma terapêutica. Para o paciente, a psicoterapia de longo prazo é o tratamento de eleição

Difficult patients - or those with difficult personalities - are frequently encountered in the treatment of chronic non-oncologic pain, overburdening the doctor-patient relationship far beyond the complexities of their illness and treatment. The present review/experiential report discusses the role that projective identification, as a psychological process of communication, puts the doctor-patient relationship in within the multi-professional chronic pain team. The concepts of projective identification are reviewed both in their benign and their malignant forms. Two clinical vignettes exemplify each of them. Some situations in the setting of doctor-patient communication are presented in which projective identification appears and complicates the therapeutic relationship. Some recommendations are offered regarding the handling of patients that communicate mainly by means of projective identification, and some ideas are offered to the multi-professional team. In our chronic pain clinic, difficult patients as a whole seem to prefer to communicate by means of a malignant form of projective identification and present with immature types of personality organizations. Within the chronic pain teams, doctor-patient relationships (as well as relations among the professionals) can be enriched if projective identification is detected early and appropriately handled. Long-term psychotherapy is the treatment that should be chosen for such patients

Coccydynia: an overview of the anatomy, etiology, and treatment of coccyx pain.

BACKGROUND: Despite its small size, the coccyx has several important functions. Along with being the insertion site for multiple muscles, ligaments, and tendons, it also serves as one leg of the tripod-along with the ischial tuberosities-that provides weight-bearing support to a person in the seated position. The incidence of coccydynia (pain in the region of the coccyx) has not been reported, but factors associated with increased risk of developing coccydynia include obesity and female gender. METHODS: This article provides an overview of the anatomy, physiology, and treatment of coccydynia. RESULTS: Conservative treatment is successful in 90% of cases, and many cases resolve without medical treatment. Treatments for refractory cases include pelvic floor rehabilitation, manual manipulation and massage, transcutaneous electrical nerve stimulation, psychotherapy, steroid injections, nerve block, spinal cord stimulation, and surgical procedures. CONCLUSION: A multidisciplinary approach employing physical therapy, ergonomic adaptations, medications, injections, and, possibly, psychotherapy leads to the greatest chance of success in patients with refractory coccyx pain. Although new surgical techniques are emerging, more research is needed before their efficacy can be established.

Transcutaneous pulsed radiofrequency treatment for patients with shoulder pain booked for surgery: a double-blind, randomized controlled trial.

Shoulder pain is the third most common musculoskeletal problem and accounts for 5% of general practitioner consultations. Although many treatments are described, there is no consensus on optimal treatment and up to 40% of patients still have pain 12 months after initially seeking help for pain. Previously, the effect of transcutaneous pulsed radiofrequency treatment (TCPRFT) was evaluated in a retrospective audit that showed good pain relief for a mean 395 days and justified this randomized sham controlled trial. In this study, 51 patients entered into a randomized double-blinded, placebo controlled study of TCPRFT. Patients were assessed at 4 and 12 weeks by a blinded observer and compared with baseline. We observed sustained reductions in pain at night, pain with activity, and functional improvement at 4 and 12 weeks with active but not sham TCPRFT. The 25 subjects who received active treatment showed statistically significant reductions of 24/100 in pain at night and 20/100 of pain with activity at 4 weeks and 18/100 and 19/100, respectively, at 12 weeks from baseline. Statistically significant lower Brief Pain Inventory pain and function scores (4 and 12 weeks), improved pain self-efficacy (4 weeks), Oxford Shoulder scores (12 weeks), and internal rotation (12 weeks) were seen. Pain at both rest and shoulder elevation were not improved by active treatment. No complications were seen. This study of a simple, low risk, outpatient treatment confirms the findings of our earlier study of TCPRFT for knee pain and shoulder pain audit that transcutaneous pulsed radiofrequency treatment may help some people with painful shoulders.

Aplicação do método clínico centrado na pessoa (MCCP) com dor crônica / Application of patient-centered clinical method (PCCM) to a chronic pain patient

Propõe-se uma radical transformação do método clínico.O MCCP é dividido em seis componentes: exploraçãoda doença e da experiência de doença; entendimentodo ser na totalidade; elaboração de plano conjunto demanejo dos problemas; incorporação das dimensões depromoção e prevenção; intensificação da relação médico-paciente e ?sendo realista?. Este artigo busca desvelaro itinerário terapêutico de uma pessoa encaminhada aoAmbulatório de Diagnóstico Diferencial da UniversidadeRegional de Blumenau (FURB) para acompanhamento eavaliação, sob visão do MCCP. Trata-se de pesquisa qualitativadocumental realizada a partir do atendimento deuma pessoa do sexo feminino (M.), com dor osteomuscularcrônica e incapacitante. Foram analisados registrosmédicos e realizadas entrevistas gravadas e transcritascom a devida autorização. O foco esteve na vida conjugale laboral e a pauta nas intercorrências médicas. Foramdiscutidas expectativas, pactuados os problemas a seremenfrentados e revisada a sua experiência com medicações.Antes da aplicação do MCCP, M. não sabia dizerpor que havia feito tantos exames, cirurgias e tomadotantos remédios. Agora entende informações a respeitode sua doença, expressa suas opiniões e compartilha decisões.Ao usar o MCCP entende-se melhor o processo deadoecimento, proporcionando consulta mais satisfatóriapara as partes envolvidas na aliança terapêutica. Há umaevidente relação entre a inclusão das várias dimensõesreferentes à perspectiva da pessoa e o resultado da consultamédica. Essa vantagem justifica as propostas deatendimento médico apoiado no modelo centrado napessoa.

A radical transformation of the clinical method isproposed. The PCCM is divided into six components: assessmentof the illness and its experience; comprehensionof the individual as a whole; design of a commonproblem management; incorporating promotion andprevention dimensions; intensification of the doctor--patient relationship and ?being realistic?. This articleaims at unveiling the therapeutic itinerary of a personreferred to the Differential Diagnostics Ambulatoryof the Regional University of Blumenau (FURB) for assessmentand follow-up, under the PCCM perspective.This is a qualitative documental research conductedfrom the care of a female person (M.), with chronic anddisabling osteomuscular pain. Medical records wereanalyzed and with due consent interviews were recordedand transcribed. The focus was on the marital andthe working affairs, and the schedule on the medical intercurrences.The expectancies were discussed, the problemsto be dealt with were agreed, and her experiencewith the medication was revised. Before the applicationof the PCCM, M. wasn?t aware of the reason she had undergoneso many exams and taken so many medicines.Currently she comprehends information about her disease,expresses her opinion and shares decisions. Byusing the PCCM the process of sickening is better understood,providing a more satisfying consultation forthe involved parts in the therapeutic alliance. Thereis an evident relation between the inclusion of manydimensions concerning the person?s perspective andthe results of the medical consultation. This advantagejustifies the proposals of medical care/service based onthe person-centered model.

Burning Mouth Syndrome.

The aetiology of BMS remains an enigma, however novel evidence suggests a neuropathic basis, which may explain concomitant vulvodynia in some patients.The constant high level spontaneous chronic pain in BMS has significant functional and psychological repercussions for these patients.Cognitive behavioural therapy remains the sole evidence based management of this condition, whilst some patients respond to treatment with Tricyclic antidepressants, SSRIs or SNRIs, compliance with medication remains an issue due to pharma side effects.Increasing evidence suggests that there may be 3 subgroups that should be managed differently.

Chronic Post Surgical Pain.

Chronic post-surgical pain (CPSP) is a recognised adverse consequence of surgery; surgery is common, therefore the population at risk is considerable.Putative risk factors for CPSP include genetic predisposition, demographic, clinical (pain history, type of surgery, anaesthesia, acute pain severity), and psychological factors (vulnerability vs resilience).Evidence of prevention is limited: long-term benefit from pre-emptive/perioperative analgesia has not been demonstrated consistently.Large scale prospective studies with detailed pre, intra and postoperative multifactorial assessments are required to refine understanding of the aetiology and prognosis of CPSP.

Intrathecal drug delivery system in the treatment of chronic intractable pain: a report of 18 cases / 中华麻醉学杂志

From November 2003 to May 2010, intrathecal drug delivery system (IDDS) was implanted in 18 patients with chronic intractable pain. Analgesia was provided with morphine. Thirteen patients suffered from late stage cancer and 5 from diseases other than cancer. VAS score was used to measure intensity of pain in all 18patients. QLQ-C30 score was used to evaluate quality of life in cancer patients. The patients were followed up for 3-62 months in 5 non-cancer patients. All 13 cancer patients died at 57 days-10 months after operation. VAS scores were significantly decreased and QLQ-C30 scores increased by intrathecal administration of morphine. Side effects developed in all patients to some extent including nausea, vomiting, constipation, urinary retention, pruritus and over-sedation and vanished in a week. Intrathecal catheter was cut while being pulled out of the needle in 1 patient. Two patients developed low intracranial pressure after operation. Cerebrospinal fluid leakage occurred in 1 patient. One patient developed neuropathic pain in the posterolateral side of right leg.
