- Background Phantom phenomena – pain or other sensations appearing to come from amputated body parts – are frequent consequences of amputation and can cause considerable suffering. Also, stump pain, located in the residual limb, is in the literature often related to the phantom phenomena. The condition is not specific to amputated limbs and has, to a lesser extent, been reported to be present after radical surgery in other body parts such as breast, rectum and teeth. Multi-causal theories are used when trying to understand these phenomena, which are recognized as the result of complex interaction among various parts of the central nervous system confirmed in studies using functional brain imaging techniques. Functional brain imaging has yielded important results, but without certainty being related to phantom pain as a subjective clinical experience. There is a wide range of treatment methods for the condition but no documented treatment of choice. Aims In this study a qualitative, explorative and prospective design was selected, in the aim to understand the patients’ personal experience of phantom phenomena. The research questions focused at how patients affected by phantom pain and or phantom sensations describe, understand, and live with these phenomena in their daily life. This study expanded ‘phantom phenomena’ to also encompass phantom breast phenomenon. Since the latter phenomenon is not as well investigated as the phantom limb, there is clinical concern that this is an underestimated problem for women who have had breasts removed. Methods The present study forms the first part of a larger, longitudinal study. Only results associated with data from the first interviews with patients, one month after an amputation, are presented here. At this occasion, 28 patients who had undergone limb amputation (20) or mastectomy (8) were interviewed. The focused, semi-structured interviews were recorded, transcribed, and then analyzed using discourse-narrative analysis. Results The interviewees had no conceptual problems in talking about the phenomena or distinguishing between various types of discomfort and discomfort episodes. Their experience originated from a vivid, functioning body that had lost one of its parts. Further, the interviewees reported the importance of rehabilitation and advances in prosthetic technology. Loss of mobility struck older amputees as loss of social functioning, which distressed them more than it did younger amputees. Phantom sensations, kinetic and kinesthetic perceptions, constituted a greater problem than phantom pain experienced from the amputated body parts. The descriptions by patients who had had mastectomies differed from those by patients who had lost limbs in that the phantom breast could be difficult to describe and position spatially. The clinical implication of this study is that when phantom phenomena are described as everyday experience, they become a psychosocial reality that supplements the definition of phantom phenomena in scientific literature and clinical documentation. Conclusions There is a need for clinical dialogues with patients, which besides, providing necessary information about the phenomena to the patients creates possibilities for health professionals to carefully listen to the patients’ own descriptions of which functional losses or life changes patients fear the most. There is a need for more qualitative studies in order to capture the extreme complexity of the pain–control system will be highlighted.

Phantom phenomena – Their perceived qualities and consequences from the patient’s perspective
- 2012

In: Scandinavian Journal of Pain. - : Elsevier. - 1877-8860 .- 1877-8879. ; 3:3, s. 134-140

Journal article (peer-reviewed)abstract
- Background and aim: The curious phenomenon phantom limbs early became the object of research, and its underlying mechanisms have been discussed over the years. The complex nature of phantom phenom- ena makes interpretation of the results ambiguous, regarding both prevalence and the accompanying suffering. There is a lack of knowledge about how amputees experience the meaning and consequences of phantom phenomena. The present aim, therefore, was to investigate how individuals, in an interview situation, described the qualities of possible perceived phantom phenomena, and how their experience affected their lives one month after the amputation/mastectomy.Methods: Twenty-eight women and men who had undergone a limb amputation or mastectomy were interviewed. The focused, narrative-oriented interviews were transcribed verbatim and the scripts were analysed with content analysis.Results: One month after the amputation the informants described and related their phantom pain and phantom sensations in sensory-discriminative, motivational-affective and cognitive-evaluative dimen- sions. The phantom sensations were experienced mainly as more agonizing than the phantom pain.Despite both the high intensity of and the high annoyance at the phantom pain and phantom sensations, a majority felt that the phantom phenomena were not a hindrance in their attempts to recapture ordinary life. But when the hindrance was evaluated as high, the annoyance was evaluated as the highest possible for both phenomena or for the phantom sensations alone, never for phantom pain alone. The interviewees’ reported attitudes of hindrance were also described and estimated in the light of their sociocultural circumstances. Thus, other preceding and/or co-existent pain conditions as well as factors such as pre- operative information, the respondents’ views on pain treatment, and their knowledge and understanding of phantom phenomena were mentioned and related to the pain-producing situation.Two-thirds of the interviewees had received post-surgical information and for some, the phenomena were well-known from earlier experience. A majority applied some version of the medical explanation model, irrespective of age or level of education. However neither information nor medical explanation, or both, sufficed for them to understand their own phantom phenomena. Thus, differences between the concepts explanation and understanding seemed significant for the annoyance related to the phantom phenomena.Regarding background data: (i) the majority of the interviewees had had pre-amputation pain prob- lems; (ii) the breast-cancer phantoms differed in several ways; (iii) there were some age and gender differences in the descriptions of hindrance.Conclusions and implications: These findings highlight the importance of observing the individual approach to the phenomena as a process of evaluation and selection. In addition, experience and under- standing of the phantoms also have sociocultural aspects. There follows the need for individualized communication and information from the clinician, and for incorporating a socioscientific and meaning- centred approach in future studies. The present insights could also be of value in other iatrogenic pain conditions.

High risk of depression and suicide attempt among chronic pain patients : always explore catastrophizing and suicide thoughts when evaluating chronic pain patients
- 2014
-
In: Scandinavian Journal of Pain. - : Elsevier. - 1877-8860 .- 1877-8879. ; 5:1, s. 1-3

Journal article (peer-reviewed)abstract
- A grave but important problem in the treatment of pain, is suicide. While many chronic pain problems are not life threatening, self-harming, e.g. suicide attempts are. Clinicians may ask whether suicide-risk is actually higher in a population of patients with chronic pain. In this issue of the Scandinavian Journal of Pain Elsebeth Stenager and her co-workers publish an important study in which they have combined the WHO research database in Odense on all suicide attempts in Southern Denmark with the database on patients referred to the multidisciplinary university pain clinic in Odense,Denmark. The WHO-database comprises only suicide attempts that resulted in hospitalization, i.e. they were all serious attempts. Suicide attempts of less serious character are not registered, so the research database is probably underestimating the real number of suicide attempts. The unique strength of the Stenager et al. study is that their data are strong, objective data fromc ombining the registry data on suicide attempts with their chronic pain patient-data. This enables the researchers to compare the pain–patient–population with the general population. We are not aware of any similar research on the real risk of suicide-attempts among the many who are burdened by chronic non-cancer pain.

Cathepsin S is increased in cerebrospinal fluid from patients with neuropathic pain : A support of the microglia hypothesis in humans
- 2014
-
In: Scandinavian Journal of Pain. - : Walter de Gruyter GmbH. - 1877-8860 .- 1877-8879. ; 5:3, s. 208-209

Journal article (peer-reviewed)abstract
- Aims: Cathepsin S has been reported to be a biomarker of spinal microglial activation, a process suggested to be involved in the pathophysiology of chronic neuropathic pain. So far this has been shown only in animal experiments. The aim of this study was to investigate the concentrations of cathepsin S in human cerebrospinal fluid (CSF) samples from a well-defined patient cohort suffering from neuropathic pain as compared to controls.Methods: CSF samples from patients suffering from chronic neuropathic pain (n = 14) were analyzed for cathepsin S levels using commercial sandwich ELISAs (DY1183, R&D Systems, Minneapolis, MN, USA). Control CSF was sampled from patients undergoing minor urological surgical procedures under spinal anaesthesia (n = 70), having no obvious pain suffering.Results: The neuropathic pain group had significantly higher levels of CSF cathepsin S (median 15189 pg/mL, range 3213–40,040), than the control group (median 5911 pg/mL, range 1909–17,188) (p < 0.005, Mann–Whitney U-test).Conclusion: The results support the existence of microglial activation in chronic neuropathic pain patients. CSF Cathepsin S may serve as a potential biomarker for this specific mechanism linked to neuropathic pain. In the future, Cathepsin S inhibiting drugs might become a new treatment alternative for neurophatic pain.
