Antinociceptive effect of N-(9,13b-dihydro-1H-dibenzo[c, f]imidazo[1,5-a]azepin-3-yl)-2-hydroxybenzamide on different pain models in mice

Abstract N-(9,13b-dihydro-1H-dibenzo[c,f]imidazo[1,5-a]azepin-3-yl)-2-hydroxybenzamide (DDIAHB) is a new drug developed through molecular modelling and rational drug design by the molecular association of epinastine and salicylic acid. The present study was designed to assess the possible antinociceptive effects of DDIAHB on different pain models in male ICR mice. DDIAHB exerted the reductions of writhing numbers and pain behavior observed during the second phase in the formalin test in a dose-dependent manner. Moreover, DDIAHB increased the latency in the hot-plate test in a dose-dependent manner. Furthermore, intragastric administration DDIAHB caused reversals of decreased pain threshold observed in both streptozotocin-induced diabetic neuropathy and vincristine-induced peripheral neuropathy models. Additionally, intragastric pretreatment with DDIAHB also caused reversal of decreased pain threshold observed in monosodium urate-induced pain model. We also characterized the possible signaling molecular mechanism of the antinociceptive effect-induced by DDIAHB in the formalin model. DDIAHB caused reductions of spinal iNOS, p-STAT3, p-ERK and p-P38 levels induced by formalin injection. Our results suggest that DDIAHB shows an antinociceptive property in various pain models. Moreover, the antinociceptive effect of DDIAHB appear to be mediated by the reductions of the expression of iNOS, p-STAT3, p-ERK and p-P38 levels in the spinal cord in the formalin-induced pain model.

Alleviation of neuropathic pain by trazodone in rats

Abstract Neuropathic pain is generally characterised by an abnormal sensation (dysesthesia), an increased response to painful stimuli (hyperalgesia), and pain in response to a stimulus that does not normally provoke pain (allodynia). The present study was designed to investigate the effect of trazodone (5mg/kg and 10mg/kg) on peripheral neuropathic pain induced by partial sciatic nerve ligation in rats. Mechanical hyperalgesia, cold allodynia and thermal hyperalgesia were assessed by performing the pinprick, acetone, and hot plate tests, respectively. Biochemically, lipid peroxidation level and total calcium levels were measured. However, trazodone administration (5 and 10 mg/ kg i.p.) for 21days significantly diminished partial sciatic nerve ligation-induced neuropathic pain along with areduction in oxidative stress and calcium levels. The results of the present study suggest that trazodone is effective in attenuating partial sciatic nerve ligation-inducedpainful neuropathic states, which may be attributed to decreased oxidative stress and calcium levels.

The Relationship Between Neuroprotective Activity and Antigenotoxic and Acetylcholinesterase Inhibitory Effects of Glaucium corniculatum Extracts

Abstract The purpose of this study was to investigate the relationship between the acetylcholinesterase (AChE) inhibitory and antigenotoxic effect with the neuroprotective activity of Glaucium corniculatum methanol and water extracts rich in rutin and quercetin flavonoids. Neuroprotective activity in terms of cell survival and development against oxidative damage was measured by MTT assay and microscopic analysis in H2O2-induced NGF-differentiated PC12 (dPC12) cells. QRT-PCR and western blot hybridization method was employed for the determination of AChE inhibition of the extracts in the same cell model, and the genotoxic and antigenotoxic effects were identified with Comet assay with human lymphocytes. H2O2-induced vitality loss in dPC12 cells was inhibited in pre-treated cells with these plant extracts. Moreover, extracts stimulated neurite formation and prevented the oxidative stress-induced reduction in neurite growth. In general, it was determined that G. corniculatum methanol extract containing higher amounts of rutin and quercetin was more effective than water extract in terms of AChE inhibitory, antigenotoxic and also neuroprotective effect. In this study, it was shown for the first time that both AChE inhibitory and antigenotoxic effects of G. corniculatum may be effective in neuroprotection and it's protective and therapeutic effects against neurodegeneration may be related to the flavonoid content.

Valoración de dolor al paciente en la unidad de terapia de adultos / Pain assessment for the patient in the adult therapy unit

La mirada histórica retrospectiva del dolor nos posiciona frente a su coexistencia con la humanidad. Cada cultura tuvo su peculiar manera de afrontarlo, darle significado y tomar sus medidas de alivio. La ciencia, desde su lugar, ha desarrollado conceptos explicando razones y orígenes de su presencia. Las ciencias médicas en su anhelo de aliviar las dolencias de las personas, elaboraron escalas de evaluación del dolor. En las terapias intensivas, donde el estado de conciencia del paciente varía acorde a la necesidad que se produce a fin de resolver su patología o el motivo de ingreso a este servicio, resulta necesario valorar su estado neurológico para poder así determinar con precisión la escala de evaluación del dolor que aporte el resultado más oportuna según el momento preciso. Debido a los cuidados que lleva a cabo el profesional de enfermería con los internados, es quien permanece mayor tiempo con ellos; pudiendo cultivar una relación interpersonal más profunda, y debido a lo cual, no sólo colaborar en el alivio del dolor, sino también, si fuera necesario, ayudar a que encuentre el sentido a éste, en palabras de Travelbee. Para poder implementar dicha idea, el objetivo del presente protocolo, se define el siguiente objetivo: «Tomar acuerdo e implementar el uso adecuado y continuo de las escalas del dolor, en el paciente de terapia intensiva de adultos, de acuerdo a su grado de conciencia, a fin de reducir el dolor durante su estadía de internación[AU]

The retrospective historical view of pain positions us in front of its coexistence with humanity. Each culture had its own way of dealing with it, giving it meaning, and taking its relief measures. Science, from its place, has developed concepts explaining reasons and origins of its presence. The medical sciences in their desire to alleviate people's ailments, developed pain assessment scales. In intensive therapies, where the patient's state of consciousness varies according to the need that occurs in order to resolve their pathology or the reason for admission to this service, it is necessary to assess their neurological status in order to accurately determine the scale of pain assessment that provides the most timely result according to the precise moment. Due to the care carried out by the nursing professional with the internees, it is he who stays with them the longest; being able to cultivate a deeper interpersonal relationship, and due to which, not only collaborate in the relief of pain, but also, if necessary, help it find meaning to it, in the words of Travelbee. In order to implement this idea, the objective of this protocol, the following objective is defined: "Agree and implement the adequate and continuous use of pain scales, in the adult intensive care patient[AU]

[Basic Knowledge of Drug Pain Therapy in the Palliative Situation]. / Basiswissen zur medikamentösen Schmerztherapie in der Palliativsituation.

This review provides an overview of the basic knowledge of drug pain therapy in the palliative situation. Pain is one of the main symptoms in 60 to 90 % of cancer patients. Pain also develops with neurological and other diseases that occur in end-of-life situations. To address this symptom, a holistic strategy is required that encompasses all physical, psychological, social, and spiritual aspects of the multi-dimensional pain experience ("total pain" concept).Drug treatment for cancer pain has been based on a stepwise approach for many years, starting with non-opioid analgesics, followed by moderate and strong opioids. In contrast, today's pain management is determined more by the actual intensity of this aversive event.The pain assessment should be tailored to identify a nociceptive vs. neuropathic pain component that needs to be challenged by the most appropriate drug therapies. Non-opioid analgesics are ideal substances for relieving nociceptive pain. Antidepressants and anticonvulsants reduce the intensity of new neuropathic pain. Opioids are suitable for all types of pain, but are restricted to a second line choice. Among all opioids are tilidine and tramadol prodrugs, which only relieve pain after activation in the liver. Drug-drug interactions may also block this activation. Rapid release opioids should be used for cancer breakthrough pain. Transdermal opioid applications are recommended for swallowing disorders, but usually not to initiate pain control. An opioid switch can be performed if side effects such as hallucinations for the selected opioid are more pronounced than the pain reduction.

What Do Adult Surgical Patients Speaking Primarily Cantonese, Italian, or Portuguese Really Want to Know About Pain and Pain Management?

BACKGROUND: Surgical patients consider information about pain and pain management to be highly important (Apfelbaum, 2003). At the same time, evidence indicates that members of racial and ethnic minorities are more likely to experience inadequate pain management (Green, Anderson, Baker, Campbell, Decker, Fillingim, & Todd, 2003; Mossey, 2011). AIMS: This study investigated the needs of general day surgery patients who spoke primarily Cantonese, Italian, or Portuguese at home for information about postoperative pain. DESIGN: This was a mixed methods, descriptive study. SETTING: The day surgery unit of a large, quaternary care hospital in downtown Toronto. PARTIPANTS/SUBJECTS: Inclusion criteria were day patients who were at least 18 years of age or older and spoke primariy Cantonese, Italian or Portugues at home. and were able to read and write in their primary language. METHODS: Participants who had undergone a day surgery procedure completed a telephone information needs survey in their primary language (Cantonese, Italian, Portuguese) within 72 hours after discharge. Composite mean scores were calculated for each item. Chi-squared analyses were used to probe for intergroup differences and compare with English-fluent participants from phase 1 of this study (Kastanias, Denny, Robinson, Sabo, & Snaith, 2009). RESULTS: Sixty-three participants in total completed the survey: 21% Cantonese, 41% Italian, and 38% Portuguese. The mean age of the sample was 70 years old; 89% were born outside of Canada, and 52% were male. For the combined group, the average importance rating score range for the information items was 6.2-8.9 out of a possible score of 10. All items were rated as moderate (5-6 out of 10) to high (≥7out of 10) importance. Surgical subtype, health status, and age had no effect on the importance of any information item. There were no significant differences between the three language groups on any of the information items. This lack of difference may have been a result of a lack of power due to the small sample size of the individual language groupings. Overall, the top-ranked information items were "the plan for which drugs to take and when," "what I can do if I still have pain or side effects," and "side effects I was most likely to get." CONCLUSIONS: Similar to English-fluent participants (Kastanias et al., 2009), participants who primarily spoke either Cantonese, Italian, or Portuguese at home placed moderate to high importance on all of the information items. and neither surgical subtype, health status nor age had any effect on the importance of any item. The multilingual sample in this study placed more importance than English-fluent participants on information regarding help with paying for pain medication (p = .001) and the side effects they were most likely to experience (p < .05). Due to a paucity of literature in this area, further research is warranted. Results may assist with evaluating and improving current approaches to surgical patient pain management education.

Comparing the physical, psychological, social, and spiritual needs of patients with non-cancer and cancer diagnoses in a tertiary palliative care setting.

OBJECTIVE: The purpose was to describe the physical, psychological, social, and spiritual needs of patients with non-cancer serious illness diagnoses compared to those of patients with cancer. METHOD: We conducted a retrospective chart review of all patients with a non-cancer diagnosis admitted to a tertiary palliative care unit between January 2008 and December 2017 and compared their needs to those of a matched cohort of patients with cancer diagnoses. The prevalence of needs within the following four main concerns was recorded and the data analyzed using descriptive statistics and content analysis: •Physical: pain, dyspnea, fatigue, anorexia, edema, and delirium•Psychological: depression, anxiety, prognosis, and dignity•Social: caregiver burden, isolation, and financial•Spiritual: spiritual distress. RESULTS: The prevalence of the four main concerns was similar among patients with non-cancer and cancer diagnoses. Pain, nausea/vomiting, fatigue, and anorexia were more prevalent among patients with cancer. Dyspnea was more commonly the primary concern in patients with non-cancer diagnoses (39%), who also had a higher prevalence of anxiety and concerns about dignity. Spirituality was addressed more often in patients with cancer. SIGNIFICANCE OF RESULTS: The majority of patients admitted to tertiary palliative care settings have historically been those with cancer. The tertiary palliative care needs of patients with non-cancer diagnoses have not been well described, despite the increasing prevalence of this population. Our description of the palliative care needs of patients with non-cancer diagnoses will help guide future palliative care for the increasing population of patients with non-cancer serious illness diagnoses.

Cannabinoids versus placebo or no intervention for pain: protocol for a systematic review with meta-analysis and trial sequential analysis.

INTRODUCTION: Pain is a frequent clinical symptom with significant impact on the patient's well-being. Therefore, adequate pain management is of utmost importance. While cannabinoids have become a more popular alternative to traditional types of pain medication among patients, the quality of evidence supporting the use of cannabinoids has been questioned. The beneficial and harmful effects of cannabinoids in patients with pain is unknown. Accordingly, we aim to assess the efficacy, tolerability and safety of cannabinoids (herbal, plant-derived extracts and synthetic) compared with placebo or no intervention for any type of pain. METHODS AND ANALYSES: We will conduct a systematic review of randomised clinical trials with meta-analysis and Trial Sequential Analysis to assess the beneficial and harmful effects of cannabinoids in any dose, formulation and duration. We will accept placebo or no treatment as control interventions. We will include participants with any type of pain (acute and chronic pain, cancer-related pain, headache, neuropathic pain or any other types of pain). We will systematically search The Cochrane Library, MEDLINE, Embase, Science Citation Index and BIOSIS for relevant literature. We will follow the recommendations by Cochrane and the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. The risk of systematic errors (bias) and random errors (play of chance) will be assessed. The overall certainty of evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach. ETHICS AND DISSEMINATION: Ethical approval is not a requirement since no primary data will be collected. The findings of this systematic review will be submitted for peer-reviewed publication and disseminated in national and international conferences. DISCUSSION: Although cannabinoids are now being used to manage different pain conditions, the evidence for the clinical effects are unclear. The present review will systematically assess the current evidence for the benefits and harms of cannabinoids to inform practice and future research.

Pain Quality by Location in Outpatients with Cancer.

BACKGROUND: The McGill Pain Questionnaire (MPQ) pain quality descriptors have been analyzed to characterize the sensory, affective, and evaluative domains of pain, but have not been differentiated by pain location. AIM: To examine MPQ pain quality descriptors by pain location in outpatients with lung or prostate cancer. DESIGN: Cross sectional. SETTINGS: Eleven oncology clinics or patients' homes. SUBJECTS: 264 adult outpatients (80% male; mean age 62.2 ± 10.0 years, 85% White). METHODS: Subjects completed a 100 mm visual analogue scale of pain intensity and MPQ clinic or home visit, marking sites where they had pain on a body outline and circling from 78 verbal descriptors those that described their pain. A researcher noted next to the descriptor spontaneous comments about sites feeling like a selected word and queried the subjects about any other words to obtain the site(s). RESULTS: Pain quality descriptors were assigned to all 7 pain locations marked by ≥ 20% of 198 lung or 66 prostate cancer patients. Four pain locations were marked with pain quality descriptors significanlty (p < .05) more frequently for lung cancer (53% chest-aching, burning; 58% back-aching, stabbing; 48% head-aching, sharp; and 19% arms-aching, stabbing) than for prostate cancer, which had significantly more frequent pain locations in the abdomen (64%-aching, burning) and lower back/buttocks (55%-aching, burning). CONCLUSIONS: This type of pain characterization is innovative and has the potential to help implement targeted treatments for patients with cancer and other chronic pain conditions.

Spiritual Perspectives on Pain in Advanced Breast Cancer: A Scoping Review.

OBJECTIVES: The aim of the present review was to characterize how pain and spirituality have been conceptualized, assessed, and addressed and how these concepts may be related among women with advanced breast cancer. DESIGN: A scoping review was conducted including publications of various methodologies. DATA SOURCES: Searches were conducted in PubMed, CINAHL, PsycINFO, Cochrane Library, OpenGrey, OAIster, and a large university library database (published 2006-2018). REVIEW/ANALYSIS METHODS: Research questions and criteria were formulated at the outset, followed by identification of publications, charting data, and collating results. RESULTS: Forty-two publications met the inclusion criteria. Most (n = 33) focused exclusively on pain, five pain and spirituality, and four exclusively spirituality. Conceptual definitions were not explicitly provided but were implied. Most assessments used the 0-10 Numeric Rating Scale (pain) and qualitative methods (spirituality). Pain management primarily focused on radiotherapy and pharmaceuticals, and two publications identified spiritual interventions. No publications directly examined the impact of spirituality on pain. Findings of qualitative studies including both concepts suggest the potential value of spirituality as a mechanism to cope with pain. CONCLUSIONS: This review identified significant unmanaged pain in women with advanced breast cancer. Women identified dimensions of spirituality as important for coping with their disease. A gap in understanding spirituality and its potential influence on pain in this population was identified.

Classifying pain in transoral endoscopic thyroidectomy.

PURPOSES: Knowledge of visual analog scale (VAS) pain assessment for transoral endoscopic thyroidectomy vestibular approach (TOETVA) is limited. The purpose of this analysis was to classify the postoperative discomfort scores in patients undergoing TOETVA compared to open thyroidectomy. METHODS: Observational clinical study of patients who underwent thyroidectomy by VAS pain assessment from September 2016 to March 2017. Patients were stratified into two groups: patients eligible for TOETVA (Group TOETVA) and non-candidates for endoscopic intervention (open thyroidectomy approach-OTA). VAS was recorded in the recovery room, at 24 h, + 2, + 5, + 15, + 30, + 90 days, and 6 months after surgery. Pain assessment was stratified in VAS-lower lip, VAS-chin, VAS-jaw, VAS-anterior neck, VAS-cervical/back, VAS-swallowing, VAS-brushing, VAS-speaking, and VAS-shaving. Secondary outcome assessed were analgesic rescue dose, morbidity, operative notes, hospital stay, and histopathology. RESULTS: 41 TOETVA and 45 OTA constituted the analysis. There were differences between the TOETVA and OTA for age, gland volume, mean nodule diameter, coexistence thyroiditis, bilateral procedures, and use of drain. Operative time was longer in TOETVA. Results indicated that TOETVA was associated with reduced neck, cervical back, and swallowing VAS scores in the 24 h after surgery. Conversely, jaw and brushing teeth resulted in higher VAS score in TOETVA group. OTA patients never experienced lower lip or chin pain. The use of rescue analgesics did not differ between the two groups. CONCLUSIONS: VAS was used to measure treatment outcome in TOETVA. VAS scores achieved overall a minimal clinical importance difference from the two procedures. There appears to be both a short- and long-term different range of interpretations of pain between TOETVA and OTA.

A Deep Neural Network-Based Pain Classifier Using a Photoplethysmography Signal.

Side effects occur when excessive or low doses of analgesics are administered compared to the required amount to mediate the pain induced during surgery. It is important to accurately assess the pain level of the patient during surgery. We proposed a pain classifier based on a deep belief network (DBN) using photoplethysmography (PPG). Our DBN learned about a complex nonlinear relationship between extracted PPG features and pain status based on the numeric rating scale (NRS). A bagging ensemble model was used to improve classification performance. The DBN classifier showed better classification results than multilayer perceptron neural network (MLPNN) and support vector machine (SVM) models. In addition, the classification performance was improved when the selective bagging model was applied compared with the use of each single model classifier. The pain classifier based on DBN using a selective bagging model can be helpful in developing a pain classification system.

Cutaneous angioleiomyoma of the auricle: a painless variant of a painful tumour.

Cutaneous angioleiomyomas (ALMs) are uncommon benign tumours of the skin which derive from the smooth muscle layer of dermal blood vessels. They usually present as tender nodules in the fifth or sixth decade of life, predominantly in the legs of females. These tumours rarely present on the head and neck, especially the ear. Head and neck ALMs differ from their more common leg counterparts in that they are painless. Additionally, they do not manifest with a female predominance. Herein, a new case of a painless auricular ALM in a 63-year-old man is reported.

Pain in Osteochondral Lesions of the Ankle - an Investigation Based on Data from the German Cartilage Registry (KnorpelRegister DGOU).

BACKGROUND: The aim of the study was to investigate parameters influencing the preoperative pain intensity in patients with osteochondral lesions of the ankle. The evaluation covered patient-related parameters such as age, sex, body mass index (BMI), as well as defect-related parameters, such as localisation, size and stage (according to the classification of the International Cartilage Repair Society [ICRS] and the Berndt-Harty-Loomer classification). We also examined the correlation between the different surgical techniques and additional factors, such as debridement of an impingement or stabilisation of the ankle on the one hand, and the preoperative pain intensity on the other. MATERIAL AND METHODS: 259 patients with osteochondral lesions of the ankle were operated in 32 clinical centres between October 2014 and December 2016 and enrolled consecutively in the German Cartilage Registry (KnorpelRegister DGOU). 151 patients were available for analysis. The preoperative pain intensity was assessed at the time of surgery with online questionnaires, using the Numeric Rating Scale for pain (NRS). RESULTS: The median preoperative pain intensity in the complete study population (n = 151) was 3 (range 0 - 10). There was no correlation between the age and the preoperative pain intensity (ρ = - 0.06). Further, there was not detected a difference between the two genders according to the preoperative pain intensity (p = 0.31). In female patients a higher BMI correlated with a higher preoperative pain intensity (ρ = 0.16). Within the group of patients with a solitary treated talus lesion there was no difference according to the preoperative pain intensity between the different localizations of the defect (medial vs. lateral talus) (p = 0.82). Within the group of patients with a solitary treated talus or tibia lesion there was no correlation between the defective area or the lesion stage according to the ICRS classification on the one hand, and the preoperative pain intensity on the other (ρ = 0.09, and ρ = 0.04, respectively). According to the Berndt-Harty-Loomer classification a higher lesion stage (stage four and five) was associated with a higher preoperative pain intensity (ρ = 0.13). There was no difference according to the preoperative pain intensity between the group of patients that received a debridement of a bony or soft tissue impingement in addition to the cartilage therapy and the group of patients without this kind of additional therapy (p = 0.10). Further, there was no difference according to the preoperative pain intensity between the group of patients that received a stabilisation of the ankle joint in addition to the cartilage therapy and the group of patients without a stabilisation procedure (p = 0.83). CONCLUSION: Osteochondral lesions of the ankle can be associated with a moderate and in some cases high pain intensity. In female patients a higher BMI is associated with a higher pain intensity. Further, a higher lesion stage according to the Berndt-Harty-Loomer classification is associated with a higher pain intensity, which highlights the clinical relevance of this classification.

Pain in emergency units: correlation with risk classification categories / Dor no serviço de emergência: correlação com as categorias da classificação de risco / Dolor en el servicio de emergencia: correlación con las categorías de clasificación de riesgo

ABSTRACT Objectives: to correlate risk classification categories with the level of pain of patients in an emergency service. Method: cross-sectional study carried out in the Risk Classification of 611 patients. The variables studied were: age, gender, comorbidities, complaint duration, medical specialty, signs and symptoms, outcome, color attributed in the risk classification of and degree of pain. We used Analysis of Variance, a Chi-Square test and a Likelihood Ratio test. Results: the average age was 42.1 years (17.8); 59.9% were women; the green (58.9%) and yellow (22.7%) risk classification prevailed and hypertension (18.3%) was the most common Comorbidity. The most frequent pain intensity was moderate (25.9%). In the red category, patients presented a higher percentage of absence of pain; in the blue, mild pain; and in the green, yellow and orange categories, there was a greater percentage of intense pain (p < 0.0001). Conclusion: among the patients who presented pain, the majority reported moderate intensity. Regarding risk categories, most patients in the red category did not report pain. Those who were classified as green, yellow and orange, reported mostly intense pain. On the other hand, patients in the blue category reported predominantly mild pain.

Metodologia: estudo qualitativo, realizado em unidade pediátrica de hospital universitário na cidade de Salvador, Bahia, em 2012. Participaram do estudo três enfermeiras, duas técnicas e duas auxiliares de enfermagem. Foram realizadas entrevistas semiestruturadas, analisadas por meio da técnica de análise de conteúdo, emergindo três categorias: Identificação da dor na criança internada; Instrumentos de avaliação da dor; Prevenção e Tratamento da dor, após aprovação do estudo pelo Comitê de Ética em Pesquisa da instituição, sob o parecer de número 79/11. Resultados: foram evidenciadas intervenções prioritariamente farmacológicas em detrimento das não-farmacológicas, intervenções insuficientes e pouco resolutivas, não utilização dos instrumentos adequados, além da não participação dos pais nesse cenário. Conclusão: percebe-se a necessidade de aprofundamento científico entre a equipe para o manejo da dor, além da reprodução do modelo biomédico no que concerne ao tratamento medicamentoso.

Objective: to describe pain management in children by the nursing team. Methodology: this qualitative study in a pediatric unit of a university hospital in Salvador, Bahia, was conducted in 2012, after approval by the research ethics committee (Opinion No. 79/11). Three nurses, two technicians and two nursing auxiliaries participated in the study. Semi-structured interviews were carried out and analyzed using content analysis, from which three categories emerged: identifying pain in the hospitalized child; pain assessment instruments; preventing and treating pain. Results: findings included pharmacological interventions prioritized over non-pharmacological interventions; insufficient and ineffective interventions; failure to use appropriate instruments; and parental non-participation in this scenario. Conclusion: the team needed more in-depth scientific training in pain management, beyond reproduction of the biomedical drug treatment model.

Assessing the prognostic features of a pain classification system in advanced cancer patients.

PURPOSE: The Edmonton Classification System for Cancer Pain (ECS-CP) has been shown to predict pain management complexity based on five features: pain mechanism, incident pain, psychological distress, addictive behavior, and cognitive function. The main objective of our study was to explore the association between ECS-CP features and pain treatment outcomes among outpatients managed by a palliative care specialist-led interdisciplinary team. METHODS: Initial and follow-up clinical information of 386 eligible supportive care outpatients were retrospectively reviewed and analyzed. RESULTS: Between the initial consultation and the first follow-up visit, the median ESAS pain intensity improved from 6 to 4.5 (p < 0.0001) and the median total symptom distress score (0-100) improved from 38 to 31 (p < 0.0001). At baseline, patients with neuropathic pain (p < 0.001) and those with at least one ECS-CP feature (p = 0.006) used a higher number of adjuvant medications. At follow-up, patients with neuropathic pain were less likely to achieve their personalized pain goal (PPG) (29 vs 72%, p = 0.015). No statistically significant association was found between increasing sum of ECS-CP features and any of the pain treatment outcomes at follow-up. CONCLUSION: Neuropathy was found to be a poor prognostic feature in advanced cancer pain management. Increasing sum of ECS-CP features was not predictive of pain management complexity at the follow-up visit when pain was managed by a palliative medicine specialist. Further research is needed to further explore these observations.

Comparação do nível de dor femoropatelar, atividade física e qualidade de vida entre adolescentes do sexo feminino e masculino / Comparison of the level of patellofemoral pain, physical activity, and quality of life between female and male adolescents

OBJETIVOS: Comparar o nível da dor, o nível de atividade física e a qualidade de vida de adolescentes do sexo feminino e masculino com dor femoropatelar. MÉTODOS: Foram recrutados de escolas públicas e privadas da cidade de Presidente Prudente, São Paulo, 46 adolescentes do sexo feminino e 46 adolescentes do sexo masculino entre 12 e 18 anos. Para serem incluídos no estudo os adolescentes precisavam referir dor no joelho de início insidioso, exacerbada em algumas atividades apresentadas e com no mínimo seis semanas de duração. Além disso, os adolescentes deveriam reportar pior dor ao longo da semana anterior de pelo menos 30 mm na Escala Visual Analógica e não poderiam apresentar sinais, sintomas ou alguma ocorrência de qualquer outra disfunção no joelho. Os participantes foram solicitados a marcarem na Escala Visual Analógica o nível de dor no joelho auto reportado do último mês. A avaliação do nível de atividade física foi realizada por meio da aplicação do Baecke Questionnaire of Habitual Physical Activity e para investigar a qualidade de vida dos participantes, a subescala de qualidade de vida do questionário Knee Outcome in Osteoarthritis Survey foi utilizada. O teste t-independente foi utilizado para identificar diferenças entre os grupos em relação ao nível de atividade física, qualidade de vida e dor no joelho. RESULTADOS: Pela Escala Visual Analógica os adolescentes do sexo masculino apresentaram nível de dor no joelho no mês anterior de 5,1±1,4 e as adolescentes do sexo feminino de 4,4±1,6 (p=0,029). O escore de atividade física foi de 8,8±1,3 para os adolescentes do sexo masculino e de 7,5±1,6 para as do sexo feminino (p<0,001). A subescala de qualidade de vida resultou em 77,9±19,0 para as meninas adolescentes e em 70,8±13,5 para os adolescentes do sexo masculino (p=0,042). CONCLUSÕES: Entre adolescentes com dor femoropatelar, os do sexo masculino apresentaram maior nível de dor no joelho, maior nível de atividade física e menor qualidade de vida em comparação com as adolescentes do sexo feminino.

AIMS: To compare the level of pain, physical activity, and quality of life of female and male adolescents with patellofemoral pain. METHODS: A total of 46 female adolescents and 46 male adolescents aged 12 to 18 years were recruited from public and private schools in the town of Presidente Prudente, São Paulo, Brazil. To be included in the study, adolescents needed to report knee pain of insidious onset, exacerbated in some activities, and lasting for at least 6 weeks. In addition, adolescents should report worse pain over the previous week of at least 30 mm on the Visual Analog Scale and could not show signs, symptoms or any occurrence of any other knee dysfunction. The participants were requested to mark their self-reported knee pain in the last month on a Visual Analog Scale. The level of physical activity was evaluated by the Baecke Questionnaire of Habitual Physical Activity and the quality of life subscale of the Knee Outcome in Osteoarthritis Survey questionnaire was used to investigate the participants' quality of life. The independent t-test was used to find differences between the groups regarding the level of physical activity, quality of life, and knee pain. RESULTS: According to the Visual Analog Scale, male adolescents presented a level of knee pain of 5.1±1.4 in the previous month and female adolescents, of 4.4±1.6 (p = 0.029). The physical activity score was 8.8±1.3 for male adolescents and 7.5±1.6 for female ones (p<0.001). The quality of life subscale scores were 77.9±19.0 for adolescent girls and 70.8±13.5 for male adolescents (p=0.042). CONCLUSIONS: Among adolescents with patellofemoral pain, males had a higher level of knee pain, higher level of physical activity, and lower quality of life compared to female adolescents

Age- and Sex-Related Normative Data for the Foot Function Index in a German-Speaking Cohort.

BACKGROUND: Despite increasing popularity of the Foot Function Index (FFI), normative values are still unavailable for this self-administered score. This study was designed to generate age- and sex-related normative values for the FFI-total and for both subscales FFI-pain and FFI-disability. METHODS: We used the cross-cultural adapted and validated German version of the FFI to generate a data pool using the results of 625 individuals, including staff and visitors to our hospital and excluding persons scheduled for foot surgery or in after-treatment. RESULTS: Mean values for FFI-total were calculated: 15.3 points (95% confidence interval [CI], 13.3-16.9), 14.9 points for FFI-pain (CI, 13.3-16.5), and 15.6 for FFI-disability (CI, 13.8-17.4). Results showed higher values for FFI-total, FFI-pain, and FFI-disability for individuals older than 40 years. In general, normative values showed a tendency for higher values with age. A slightly inconsistent distribution over different age groups with a peak for individuals in their 40s and 50s was observed, especially for FFI-pain. Men had better scores than women. Individuals with previous surgery showed lower scores in their respective score. CONCLUSIONS: Our data calculated normative values for a German-speaking cohort for FFI-total as well as for both subscales FFI-pain and FFI-disability. Our data quantified the increase of FFI-total, FFI-pain, and FFI-disability normative values with age but also showed a slightly inconsistent distribution of normative values over all age groups. We demonstrated higher normative values for women and slightly higher normative values for individuals with previous foot or ankle surgery. LEVEL OF EVIDENCE: II, prospective comparative study.
