Abstract:
ERB–DUCHENNE PALSY (case study)Senatorova A.V., Khodun I.I.The frequency of damage to the brachial plexus is 0.5-2 per 1000 live births. Most of them (about 90 % cases) are Erb-Duchesnne palsy. Birth trauma of the brachial plexus occurs mainly in in full-term newborns. Correct diagnosis of Erb-Duchesnne palsy allows to avoid long-term complications as late treatment leads to disability. The article presents a clinical observation of Erb-Duchesnne palsy in a newborn patient, who was diagnosed on the first day of life. Conservative therapy was an effective strategy of baby’s recovery.Key words: Erb-Duchenne palsy, birth injury, brachial plexus, newborn.

Abstract:
ABSTRACT:Guillaume-Benjamin-Amand Duchenne was born 200 years ago in Boulogne-sur-Mer (Pas-de-Calais, France). He studied medicine in Paris and became a physician in 1831. He practiced general medicine in his native town for about 11 years and then returned to Paris to initiate pioneering studies on electrical stimulation of muscles. Duchenne used electricity not only as a therapeutic agent, as it was commonly the case earlier in the 19th century, but chiefly as a physiological investigation tool to study the anatomy of the living body. Without formal appointment he visited hospital wards across Paris searching for rare cases of neuromuscular disorders. He built a portable electrical device that he used to functionally map all bodily muscles and to study their coordinating action in health and disease. He gave accurate descriptions of many neuromuscular disorders, including pseudohypertrophic muscular dystrophy to which his name is still attached (Duchenne muscular dystrophy). He also invented a needle system (Duchenne's histological harpoon) for percutaneous sampling of muscular tissue without anesthesia, a forerunner of today's biopsy. Duchenne summarized his work in two major treatises entitled De l'électrisation localisée (1855) and Physiologie des mouvements (1867). Duchenne's iconographic work stands at the crossroads of three major discoveries of the 19th century: electricity, physiology and photography. This is best exemplified by his investigation of the mechanisms of human physiognomy in which he used localized faradic stimulation to reproduce various forms of human facial expression. The album that complements his book on this issue is considered a true incunabulum of photography. Duchenne de Boulogne, a shy but hard-working, acute and ingenious observer, became one of most original clinicians of the 19th century. He died in Paris in 1875.

Abstract:
Abstract Objective Providing care for a spouse with dementia is associated with an increased risk for poor mental health. To determine whether this vulnerability in caregivers is related to the expression of positive emotion, we examined 57 patients with Alzheimer’s disease and behavioral variant frontotemporal dementia and their spouses as they discussed a marital conflict. Method Facial behavior during the discussion was objectively coded to identify Duchenne (i.e., genuine) smiles and non-Duchenne (i.e., polite) smiles. Caregiver mental health was measured using the Medical Outcomes Survey. Results Greater expression of Duchenne smiles by patients was associated with better caregiver mental health, even when accounting for covariates (i.e., diagnosis, patient cognitive functioning, and caregiver marital satisfaction). Greater expression of non-Duchenne smiles by patients was associated with worse caregiver health, but only when covariates were entered in the model. Expression of Duchenne and non-Duchenne smiles by caregivers was not associated with caregiver mental health. Discussion Patients’ expression of Duchenne and non-Duchenne smiles may reveal important aspects of the emotional quality of the patient–caregiver relationship that influence caregiver burden and mental health.

Abstract:
The Duchenne marker has been proposed as a universal marker of smile authenticity. However, Elfenbein, Beaupré, Levesque, and Hess (2007 ) found that, whereas Canadians typically show the Duchenne marker when posing happiness, Gabonese do not. We therefore investigated whether the Duchenne marker is perceived as a marker of smile authenticity by Gabonese and by Mainland Chinese living in Quebec, Canada. The results show that Gabonese do not use the Duchenne marker to assess smile authenticity at all. Mainland Chinese immigrants to Quebec showed sensitivity to the Duchenne marker only when judging smiles by French-Canadian encoders, suggesting learning of the use of this cultural dialect through cultural exposure. In sum, the use of Duchenne marker is not universal, but rather limited to certain cultures.

Abstract:
In this retrospective cohort study, we characterize the health profile of preterm males with Duchenne muscular dystrophy. Major clinical milestones (ambulation cessation, assisted ventilation use, and onset of left ventricular dysfunction) and corticosteroids use in males with Duchenne muscular dystrophy identified through a population-based surveillance system were analyzed using Kaplan-Meier survival curves and Cox proportional hazards modeling. The adjusted risk of receiving any respiratory intervention among preterm males with Duchenne muscular dystrophy was 87% higher than among the corresponding full-term males with Duchenne muscular dystrophy. The adjusted risks for ambulation cessation and left ventricular dysfunction were modestly elevated among preterm compared to full-term males, but the 95% confidence intervals contained the null. No difference in the start of corticosteroid use between preterm and full-term Duchenne muscular dystrophy males was observed. Overall, the disease course seems to be similar between preterm and full-term males with Duchenne muscular dystrophy; however, pulmonary function seems to be affected earlier among preterm males with Duchenne muscular dystrophy.

Abstract:
Duchenne and mdx muscle tissues lack dystrophin where it normally interacts with glycoproteins in the sarcolemma. Intracellular free calcium ([Ca2+]i) is elevated in Duchenne and mdx myotubes and is correlated with abnormally active calcium-specific leak channels in dystrophic myotubes. We fused Duchenne human and normal mouse myoblasts and identified heterokaryon myotubes by Hoechst 33342 staining to measure the degree to which dystrophin introduced by normal nuclei could incorporate throughout the myotube at the sarcolemma and restore normal calcium homeostasis. Dystrophin expression in myotubes was determined by immunofluorescence and confocal laser scanning microscopy. Dystrophin was expressed at the sarcolemma in normal mouse and heterokaryon myotubes, but not in Duchenne myotubes. In heterokaryons, extensive dystrophin localization occurred at the sarcolemma even where only Duchenne nuclei were present, indicating that dystrophin does not exhibit nuclear domains. Heterokaryon, normal mouse and Duchenne myotube [Ca2+]i was measured using fura-2 and fluorescence ratio imaging. Heterokaryon and normal mouse myotubes were found to maintain similar levels of [Ca2+]i. In contrast, Duchenne myotubes had significantly higher [Ca2+]i (p < 0.001). Furthermore, the ability of heterokaryons to maintain normal [Ca2+]i did not depend on greater numbers of normal nuclei than Duchenne being present in the myotube. These results support the view that dystrophin expression in heterokaryons allows for efficient control of [Ca2+]i.

Abstract:
This study describes the amount of physical activity and perception of physical activity in boys with Duchenne muscular dystrophy (DMD) compared to healthy boys. A questionnaire described 6 domains of physical activity. Four Duchenne muscular dystrophy subgroups were made: early and late ambulatory, nonambulatory with relative good, or limited arm function. Eighty-four boys with Duchenne muscular dystrophy (15.0 ± 6.4 years) and 198 healthy boys (14.0 ± 4.3 years) participated. Daily activities were more passive for boys with Duchenne muscular dystrophy. Physical activity was less and low demanding compared to healthy boys. It decreased with disease severity ( P < .05), whereas screen time increased ( P < .05). Benefits of physical activity in boys with Duchenne muscular dystrophy were having fun and making friends. Barriers were lack of sport facilities and insufficient health. This study helps to quantify poor engagement in physical activity by boys with Duchenne muscular dystrophy, and demonstrates factors that contribute to it. Suggestions to stimulate physical activity are made.

Abstract:
Erb-Duchenne paralysis is a neurological condition characterized by paralysis of the arm which occurs due to injury of the upper trunk of C5-C6 of the brachial plexus and can lead to disturbances in movement and sensation. Erb-Duchenne paralysis commonly presents with a “Waiter’s Tip” deformity characterized by elbow extension, medial rotation of the arm, forearm pronation, and wrist flexion. Management of Erb-Duchenne paralysis may involve strengthening exercises, range of motion exercises, manual therapy, and neuromuscular electrical stimulation. However, in most cases, the diagnosis of Erb-Duchenne paralysis is not detected early enough for rehabilitation outcomes to be maximized. We herein report a case of a 6-months old child who had Erb-Duchenne paralysis in the left upper limb. The aim of this case report is to highlight the importance of early detection and rehabilitation of Erb-Duchenne paralysis. Furthermore, the report also discusses the physiotherapy techniques that can be used to optimize outcomes.

Abstract:
Background Studies with nondepolarizing neuromuscular blocking agents showed a delayed onset and prolonged recovery in patients with Duchenne muscular dystrophy. The objective of this study was to investigate if these alterations depend on disease progression. Methods The authors studied 11 children (6-9 yr) with moderate Duchenne muscular dystrophy, 11 adolescents (12-16 yr) with advanced Duchenne muscular dystrophy, and 2 age-matched control groups of 8 patients each (5-9 and 10-17 yr). Anesthesia was performed with propofol and remifentanil. Patients received a single intravenous dose of 0.2 mg/kg mivacurium. Neuromuscular transmission was monitored by acceleromyography. The time course of neuromuscular blockade was characterized by the onset time and the times to different levels of recovery. Results Onset and duration of neuromuscular blockade were significantly prolonged in adolescent Duchenne muscular dystrophy patients (onset time, 4.0 min; recovery index, 12.3 min; median), as compared with Duchenne muscular dystrophy children (onset time, 2.3 min; recovery index, 6.8 min), and also as compared with young controls (onset time, 2.0 min; recovery index, 4.4 min) and adolescent controls (onset time, 2.5 min; recovery index, 4.8 min). Within the Duchenne muscular dystrophy patients, onset time and recovery index increased significantly with age. In the control group, age had no effect. Conclusions The neuromuscular blocking effects of mivacurium showed a significant age dependency in Duchenne muscular dystrophy patients, which was most probably caused by the progression of the disease.

Abstract:
Abnormalities in X chromosomes, either numerical or structural, cause X-linked disorders, such as Duchenne muscular dystrophy (DMD). Recent molecular and cytogenetic techniques can help identify DMD gene mutations. The accurate diagnosis of Duchenne is crucial, directly impacting patient treatment management, genetics, and the establishment of effective prevention strategies. This review provides an overview of X chromosomal disorders affecting Duchenne and discusses how mutations in Dystrophin domains can impact detection accuracy. Firstly, the efficiency and use of cytogenetic and molecular techniques for the genetic diagnosis of Duchenne disease have, thus, become increasingly important. Secondly, artificial intelligence (AI) will be instrumental in developing future therapies by enabling the aggregation and synthesis of extensive and heterogeneous datasets, thereby elucidating underlying molecular mechanisms. However, despite advances in diagnostic technology, understanding the role of Dystrophin in Duchenne disease remains a challenge. Therefore, this review aims to synthesize this complex information to significantly advance the understanding of DMD and how it could affect patient care.

Abstract:
Chronic positive mood (CPM) has been shown to confer a wide variety of social, functional, and health benefits. Some researchers have argued that humans evolved to feel CPM, which explains why most people report better than neutral mood (the “positivity offset bias”) and why particularly happy people have particularly good outcomes. Here, we argue that the Duchenne smile evolved as an honest signal of high levels of CPM, alerting others to the psychological fitness of the smiler. Duchenne smiles are honest because they express felt positive emotion, making it difficult for unhappy people to produce them. Duchenne smiles enable happy people to signal and cooperate with one another, boosting their advantages. In our literature review, we found (a) that not all Duchenne smiles are “honest,” although producing them in the absence of positive emotion is difficult and often detectable, and (b) that the ability to produce and recognize Duchenne smiles may vary somewhat by a person’s cultural origin. In the final section of the article, we consider behavioral influences on CPM, reviewing research showing that engaging in eudaimonic activity reliably produces CPM, as posited by the eudaimonic-activity model. This research suggests that frequent Duchenne smiling may ultimately signal eudaimonic personality as well as CPM.

Abstract:
The Duchenne smile is the genuine smile characterized by the activation of the muscles around the eyes and mouth. It has been associated, in the specialized literature, with the experience of positive emotions. Through the present work, using a qualitative approach, we aimed to identify and systematize the studies carried out in the period 2010-2023 that investigated the relationship between the Duchenne smile and positive emotions. Following the application of specific keywords, 611 studies were identified, from which, after applying the inclusion-exclusion criteria, 8 studies were included in the review. A conclusion could not be drawn regarding the idea that the Duchenne smile is indisputably an indicator of positive emotions, but the data provide us with important information such as the following: the Duchenne smile is associated with experiencing positive emotions (happiness, joy, hope, contentment) and manifests itself in the context of affiliation and cooperation. It has an important role in triggering extended cognitive states (attentional ones) and can be performed voluntarily (in the presence/absence of a positive emotion), having the same health benefits as spontaneous smiling. In addition, the Duchenne smile increases the acceptance rate of feedback given by teachers in class. The relationship between the Duchenne smile and positive emotions is context dependent.

Abstract:
Obstetric practice dates back thousands of years, providing assistance to women in labor is often complicated by the rapid course of labor, pelvic presentation of the fetus, shoulder dystocia with a possible clavicle fracture. Damage to CV–CVI roots, classic Duchenne–Erb palsy, accounts for 46 % of the total number of obstetric palsies. Objective. To analyze the scientific and medical literature in order to identify historical scientific and practical information about the study of childbirth injuries, and, in particular, Duchenne–Erb's obstetric palsy. Methods. To study and analyze sources of scientific and medical information, publications from Google search engines, electronic databases PubMed, Google Scholar, archival medical journals. Results. The first data on obstetric paralysis were provided by Duchesne in 1872, highlighting thorough reports on upper extremity muscle damage. Subsequently, in 1874, Erb performed electrical stimulation of the affected muscles, finding out the zone of neurological damage. The history of the development and formation of this scientific issue is quite ambiguous, because it borders on two medical fields: neurosurgery and orthopedics. According to literary sources, it is obvious that the pathohistology and pathophysiology of the direct injury zone (roots CV–CVI), delayed changes in the function of the upper limb, and the latest diagnostic technologies simplify the understanding of the presentation. The existing methods of operative interventions allow physicians to improve the child's life. However, the question remains open regarding the use of certain operative interventions in relation to the child's age and further rehabilitation. Conclusions. Despite a significant stratum of scientific and practical research on Duchenne–Erb's obstetric palsy, there are still a number of questions regarding the diagnosis and treatment of children with this abnormality. The search for improving the functional state of the upper limb in children should continue.

Abstract:
Duchenne muscular dystrophy (DMD/Duchenne) is a progressive X-linked disease and is the most common pediatric-onset form of muscular dystrophy, affecting approximately 1:5000 live male births. DNA testing for mutations in the dystrophin gene confirms the diagnosis of this disorder. This study involves assessment of screening newborns for DMD using an immunoassay for muscle-type (MM) creatine kinase (CK) isoform—the GSP Neonatal CK-MM kit. Comparisons were made with CK activity determination by fluorescence measurement. In addition, the study evaluated the effect of gestational age, age of infant at time of sampling and how stable the CK-MM was over time. This assay discriminates well between normal, unaffected and Duchenne affected populations and is suitable for Duchenne newborn screening.
