Incidence of acute radiodermatitis in women with breast cancer undergoing hypofractionated radiotherapy

ABSTRACT Objective: To estimate the incidence and degree of acute radiodermatitis at the end and after the end of treatment in women with breast cancer undergoing hypofractionated radiotherapy. Methods: Observational, prospective, and longitudinal study, conducted between March 2019 and January 2020, in a radiotherapy outpatient clinic. Results: Thirty-two women participated in the study, among whom, in the last session of hypofractionated radiotherapy, 15 (46.9%) had radiodermatitis, erythema in 13 (40.6%), and wet peeling in 2 (6.3%). In the post-treatment evaluation, 27 (84.4%) had radiodermatitis, erythema in 17 (53.1%), dry peeling in 8 (25%), and wet peeling in 2 (6.3%). Conclusion: The general incidence of radiodermatitis after hypofractionated radiotherapy in women with breast cancer was 37.5%, erythema, 12.5%, and dry peeling, 25%. The development of care protocols for the management of radiodermatitis after treatment is of paramount importance.

The role of 18F-FDG PET/CT in diagnosis and treatment evaluation for ocular adnexal mucosa-associated lymphoid tissue lymphoma

Objective: The purpose of this study is to evaluate the value of fluorine-18-fludeoxyglucose positron emission tomography (18F-FDG PET)/CT in the diagnosis and treatment evaluation of ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: 70 patients with OAML who received radiotherapy were recruited in our study. All the patients had the 18F-FDG PET/CT examination before the treatment. We retrospectively reviewed the medical records, pathological reports, laboratory results, and imaging features of all patients. The associations between 18F-FDG PET/CT parameters and Epstein-Barr virus antibodies, treatment response, MRI data, and Ki-67 expression were investigated. Results: The PET/CT scan indicated that 80% (56/70) of the patients showed orbital FDG avidity. The median level of maximum standardized uptake value (SUVmax) of the lesions was 4.65 ± 3.00 (range:1.2–13.5). 92.0% (46/50) of the mass-forming lesions showed 18F-FDG avidity, while only 50.0% (10/20) of the non-massive lesions had 18F-FDG avidity (χ2 = 13.23, p=0.01). The SUVmax in orbit, conjunctiva, and lacrimal gland lymphoma were 5.6, 2.9, and 3.7, respectively. A significant difference was identified of SUVmax among the three locations’ lymphoma using one-way ANOVA analysis (F = 5.039, p = 0.01). After completion of radiotherapy, the complete remission rate was achieved in 30.8% (4/13) of the patients without 18F-FDG avidity, and 70.4% (38/54) in cases with 18F-FDG avidity (χ2 = 5.43, p = 0.02). The correlation between high Ki-67 score and 18F-FDG avidity was confirmed (χ2 = 3.916, p = 0.048); however, no significant correlation was found between the SUVmax and Ki-67 score of the lesions (p = 0.971). Three patients (3/70, 4.3%) were upregulated the stage via PET/CT. Conclusion: 18F-FDG PET/CT had some potential values in the diagnosis and assessment of treatment response in patients with OAML. Advances in knowledge: The value of 18F-FDG PET/CT for patients with OAML.

Indication and uses of temporary anchorage device in orthodontic

Treating various types of malocclusion is dependant on providing a secure anchorage. In this context, it has been shown that teeth, intramaxillary, and/or extraoral appliances are required to achieve favorable outcomes regarding anchorage treatment. A Temporary anchorage device (TAD) has been introduced in the literature in this context. It has been described as a temporary device that can be used after completing treatment. The aim of the study was to review the indications and uses of TADs in orthodontic treatment. The current evidence shows that introducing TADs in the field of orthodontic treatment has been associated with favorable outcomes that encountered the previous multiple challenges reported with the conventional anchorage approaches. Contemporary orthodontic settings reported various uses for TADs, including corrections in transverse, vertical, and anteroposterior dimensions. Combined use of TADs and conventional approaches were also evaluated with favorable outcomes. These findings indicate the validity of TADs in orthodontic treatment and call for its future implications and clinical applications. However, it should be noted that post-treatment evaluation on a long-term basis was not adequately reported in the current literature, indicating the need for future investigations for further validation.

Adaptation and validation of two autism-related measures of skills and quality of life in Ethiopia

Although most children with autism and other neurodevelopmental disorders live in low- and middle-income countries, assessment tools are lacking in these settings. This study aims to culturally adapt and validate two questionnaires for use in Ethiopia: the Autism Treatment Evaluation Checklist and the Pediatric Quality of Life Inventory™ Family Impact Module. Both questionnaires were adapted to be suitable for administration in low-literate caregivers and translated using the backward translation procedure. The factor structure, reliability and validity were investigated using caregiver-reports on 300 children with neurodevelopmental disorders or physical health conditions. Confirmatory factor analysis of the Pediatric Quality of Life Inventory™ Family Impact Module data indicated an acceptable fit of the hypothesised eight-factor structure. Internal consistency was high for both measures. Test–retest reliability was excellent for the Autism Treatment Evaluation Checklist and moderate to excellent for the Pediatric Quality of Life Inventory™ Family Impact Module. Both questionnaires demonstrated adequate known-group validity, with moderate to very large effect size group differences between case and control groups. The questionnaires correlated moderately with each other. In conclusion, the Ethiopian adaptations of the Autism Treatment Evaluation Checklist and the Pediatric Quality of Life Inventory™ Family Impact Module are valid and reliable tools for use in parents of children with neurodevelopmental disorders including autism. These adapted measures may also be valuable for use in other low-income settings. Lay abstract Although most children with autism and other neurodevelopmental disorders live in low- and middle-income countries, reliable tools to assess these conditions are often not available in these settings. In this study, we adapted two questionnaires developed in Western high-income contexts for use in Ethiopia – the Autism Treatment Evaluation Checklist and the Pediatric Quality of Life Inventory™ Family Impact Module. Both measures are completed by a child’s caregiver and both are relatively short and easy to complete. The Autism Treatment Evaluation Checklist is used to monitor the developmental issues of the child, while the Pediatric Quality of Life Inventory™ Family Impact Module measures the impact of the child’s condition on the caregiver. We translated both tools into the Ethiopian language Amharic, and adapted them to the local cultural context. Three hundred caregivers, half of whom were parents of children with neurodevelopmental disorders, and half were parents of children with physical health problems, completed the questionnaires through a face-to face interview, so that non-literate caregivers could also take part. Both tools performed adequately, measured what we aimed to measure and were reliable. Both the Autism Treatment Evaluation Checklist and Pediatric Quality of Life Inventory™ are suitable tools to assess children with developmental and other health problems in Ethiopia and their caregivers. We believe that more similar tools should be developed or adapted for use in low-income countries like Ethiopia, to gain a better understanding of developmental problems in those settings, and allowing clinicians and service providers to use these tools in their practice. Moreover, these tools can be used in future studies to evaluate interventions to improve support for families.

Functional assessment of stretch hyperreflexia in children with cerebral palsy using treadmill perturbations

Background As hyperactive muscle stretch reflexes hinder movement in patients with central nervous system disorders, they are a common target of treatment. To improve treatment evaluation, hyperactive reflexes should be assessed during activities as walking rather than passively. This study systematically explores the feasibility, reliability and validity of sudden treadmill perturbations to evoke and quantify calf muscle stretch reflexes during walking in children with neurological disorders. Methods We performed an observational cross-sectional study including 24 children with cerebral palsy (CP; 6–16 years) and 14 typically developing children (TD; 6–15 years). Short belt accelerations were applied at three different intensities while children walked at comfortable speed. Lower leg kinematics, musculo-tendon lengthening and velocity, muscle activity and spatiotemporal parameters were measured to analyze perturbation responses. Results We first demonstrated protocol feasibility: the protocol was completed by all but three children who ceased participation due to fatigue. All remaining children were able to maintain their gait pattern during perturbation trials without anticipatory adaptations in ankle kinematics, spatiotemporal parameters and muscle activity. Second, we showed the protocol’s reliability: there was no systematic change in muscle response over time (P = 0.21–0.54) and a bootstrapping procedure indicated sufficient number of perturbations, as the last perturbation repetition only reduced variability by ~ 2%. Third, we evaluated construct validity by showing that responses comply with neurophysiological criteria for stretch reflexes: perturbations superimposed calf muscle lengthening (P < 0.001 for both CP and TD) in all but one participant. This elicited increased calf muscle activity (359 ± 190% for CP and 231 ± 68% for TD, both P < 0.001) in the gastrocnemius medialis muscle, which increased with perturbation intensity (P < 0.001), according to the velocity-dependent nature of stretch reflexes. Finally, construct validity was shown from a clinical perspective: stretch reflexes were 1.7 times higher for CP than TD for the gastrocnemius medialis muscle (P = 0.017). Conclusions The feasibility and reliability of the protocol, as well as the construct validity—shown by the exaggerated velocity-dependent nature of the measured responses—strongly support the use of treadmill perturbations to quantify stretch hyperreflexia during gait. We therefore provided a framework which can be used to inform clinical decision making and treatment evaluation.

Relationship between Competency to Consent to Treatment and Psychological Well-Being: Mediating Effect of Empowerment and Emotion

This study was conducted to evaluate the competency to consent to the treatment of psychiatric outpatients and to confirm the role of empowerment and emotional variables in the relationship between competency to consent to treatment and psychological well-being. The study participants consisted of 191 psychiatric outpatients who voluntarily consented to the study among psychiatric outpatients. As a result of competency to consent to treatment evaluation, the score of the psychiatric outpatient’s consent to treatment was higher than the cut-off point for both the overall and sub-factors, confirming that they were overall good. In addition, the effect of the ability of application on psychological well-being among competency to consent to treatment was verified using PROCESS Macro, and the double mediation effect using empowerment and emotional variables was verified to provide an expanded understanding of this. As a result of the analysis, empowerment completely mediated the relation between the ability of application and psychological well-being, and the relation between the ability of application and psychological well-being was sequentially mediated by empowerment and emotion-related variables. Based on these findings, the implications and limitations of this study were discussed.
