Sleep Disturbances and Fatigue in Adolescents with Cancer Receiving Chemotherapy

Sleep disturbances and fatigue are frequently complained by adolescents with cancer. These problems will lead to a variety of changes that may affect adolescents’ development. However, there is very limited data concerning adolescents with cancer in Indonesia. The research aims to explore sleep disturbances and fatigue in adolescents with cancer who are receiving chemotherapy. The research applies a qualitative design with phenomenology approach. Data were collected using in-depth interviews with seven adolescents with cancer in Jakarta, Bogor, and Bekasi. The interviews involved open questions on seven aspects, consisting of level of fatigue, responses to psychological drives, sleep disturbances, sleep disruption due to illness and chemotherapy, disruptions in some aspects of daily life, responses to problematic situations, and general perspective on life. Participants stated that chemotherapy induced sleep disturbances and fatigue, and this situation greatly influenced their overall quality of life. These problems are interrelated to each other and may affect the success of chemotherapy program. In terms of nursing, this research also shows the importance of developing a more effective system for managing sleep disturbances and fatigue during chemotherapy program

Limb amputations in fixed dystonia: a form of body integrity identity disorder?

Fixed dystonia is a disabling disorder mainly affecting young women who develop fixed abnormal limb postures and pain after apparently minor peripheral injury. There is continued debate regarding its pathophysiology and management. We report 5 cases of fixed dystonia in patients who sought amputation of the affected limb. We place these cases in the context of previous reports of patients with healthy limbs and patients with chronic regional pain syndrome who have sought amputation. Our cases, combined with recent data regarding disorders of mental rotation in patients with fixed dystonia, as well as previous data regarding body integrity identity disorder and amputations sought by patients with chronic regional pain syndrome, raise the possibility that patients with fixed dystonia might have a deficit in body schema that predisposes them to developing fixed dystonia and drives some to seek amputation. The outcome of amputation in fixed dystonia is invariably unfavorable

Virtual reality body exposure therapy for anorexia nervosa. A case report with follow-up results

Objective: Exposure-based therapies such as mirror exposure may help to improve the results of classic cognitive behavioral therapy in anorexia nervosa (AN). Virtual reality (VR)-based procedures provide interesting novelties for targeting body-related concerns. This study aimed to provide preliminary evidence of the usefulness of a VR body exposure therapy in a patient diagnosed with AN. Method: Fear of gaining weight (FGW), body anxiety, drive for thinness, body image disturbances, body mass index and body-related attentional bias were assessed before and after the intervention, as well as five months later. Five sessions of VR body exposure therapy were included within the standard course of cognitive behavioral therapy. The sessions involved a systematic and hierarchical exposure of the patient to a virtual representation of her own silhouette, with the body mass index of the avatar progressively increasing in subsequent sessions. Results: After the intervention, there was a clear reduction in AN symptoms such as the FGW, drive for thinness, body-related anxiety and dissatisfaction. Body mass index values rose continuously during the intervention and reached healthy levels. Finally, there was a notable change in the dysfunctional body-related attentional bias. Almost all these improvements were maintained after five months, except for the FGW. Conclusion: To the best of our knowledge, this study is the first to focus on treating the FGW and body-related concerns in AN using a VR-based paradigm. To pursue this study further and assess the effectiveness of this new VR software, larger controlled clinical trials are needed

PTSD from Childhood Trauma as a Precursor to Attachment Issues

The past 20 years have been turbulent regarding Reactive Attachment Disorder (RAD), with conflicting research about its causes, effects, treatment, and prognosis. The current diagnostic criteria in the DSM-5 fails to adequately address this disorder. A number of deviant and maladaptive behaviors common amongst children with RAD are not even mentioned in the diagnostic criteria. As such, the diagnostic definition is almost unidentifiable or incompatible with real-life conduct manifestations of the disorder. Rather, this author contends that RAD is foundationally a unique and extreme form of Posttraumatic Stress Disorder (PTSD) from Early Childhood Trauma. The child endured unspeakable neglect and/or abuse in his early years by someone who was supposed to protect him, and he, understandably, is terrified of trusting anyone lest that person harm him, too. These children dissociate and experience PTSD flashbacks to prior abusers when a new caregiver yells at them or has angry, disapproving eyes. The underlying issues are that child does not feel safe and does not trust his parents to protect him, due to past trauma. This author contends that this is the core causation of RAD and the myriad of behaviors that RAD children employ to maintain control of their environment. This etiological stance naturally leads to treatment implications. Treatment becomes systemic as well as individual. An explicit and detailed case study ties together all of the elements of this new etiology by addressing the presenting issues, case conceptualization, and treatment plan for a family with an adopted child

The Modus Vivendi of Persons with Schizophrenia: Valueception Impairment and Phenomenological Reduction

So far, the value dimension underlying affectivity disorders has remained out of focus in phenomenological psychopathology. As early as at the beginning of the 20th century, however, German phenomenologist Max Scheler examined in depth the relationship between affectivity and value dimension through the concept of valueception (Wertnehmung). In this sense, a recent noteworthy contribution has been provided by John Cutting, who has drawn attention to the importance of Scheler’s analyses for psychiatry. In this work I take into consideration only two aspects of Cutting’s proposal: 1) the relationship between the impairments of valueception and the perception of certain value classes; and 2) the interpretation of Scheler’s phenomenological reduction and its juxtaposition with the modus vivendi of schizophrenia. According to Cutting, in the modus vivendi of schizophrenia the valueception impairment entails putting vital values in brackets and focusing on personal values, with a process that recalls Scheler’s phenomenological reduction. Regarding the first aspect, I share Cutting’s starting point, but then shift the focus on how important the valueception is for the intersubjective dimension. In particular, I maintain that rather than compromising the perception of vital values, valueception impairments in the modus vivendi of schizophrenia interfere with the intersubjective dimension and are interwoven with a process of disembodiment. My thesis is that the modus vivendi of schizophrenia involves a disturbance of the intersubjective dimension that arises from the level of valueception and that determines the person’s self-referential closure. With regard to the second point, by analyzing Scheler’s phenomenological reduction, I sustain that its main objective is to increase both the interaction with otherness and the openness to the world (Weltoffenheit). As a consequence, the modus vivendi of schizophrenia, in my opinion, is not comparable, as Cutting claims, with Scheler’s phenomenological reduction, but goes in a different directio

Cavlectometry: Towards Holistic Reconstruction of Large Mirror Objects

We introduce a method based on the deflectometry principle for the reconstruction of specular objects exhibiting significant size and geometric complexity. A key feature of our approach is the deployment of an Automatic Virtual Environment (CAVE) as pattern generator. To unfold the full power of this extraordinary experimental setup, an optical encoding scheme is developed which accounts for the distinctive topology of the CAVE. Furthermore, we devise an algorithm for detecting the object of interest in raw deflectometric images. The segmented foreground is used for single-view reconstruction, the background for estimation of the camera pose, necessary for calibrating the sensor system. Experiments suggest a significant gain of coverage in single measurements compared to previous methods. To facilitate research on specular surface reconstruction, we will make our data set publicly available

Weight Stigma, Cognitions, and Disordered Eating

Weight stigma experiences affect people of all weights and have many negative consequences; despite this, weight stigma is still an acceptable prejudice in our society. Research has established that weight stigma is predictive of disordered eating (DE) cognitions, which are, in turn, predictive of DE behaviors. The current study explored the unique contribution DE cognitions make to DE behaviors while controlling for other DE cognitions. The DE cognitions examined in the current study were drive for thinness, weight bias internalization, and perfectionism. The DE behaviors examined were emotional eating, restrained eating, inappropriate compensatory behaviors, and binge-eating. Weight bias internalization and drive for thinness were the only DE cognitions found to make unique contributions to distinct DE behaviors. The DE cognitions were further found to be significant mediators of the relation between weight stigma experiences and the related DE behaviors. Implications with respect to prevention and treatment are discussed
