- Abstract
Background: This study aimed to mimic the changes from Charcot neuropathic arthropathy in humans by examining the effects of exposing diet-induced obese (DIO) mice to neurotrauma through a regimented running protocol. Methods: Forty-eight male wild-type C57BL/6J mice were obtained at age 6 weeks and separated into 2 groups for diet assignment. After a 1-week acclimation period, half of the mice consumed a high-fat diet (60% fat by kcal) ad libitum to facilitate neuropathic diet-induced obesity whereas the other half were control mice and consumed an age-matched standard low-fat control diet (10% fat by kcal). At age 12 weeks, half of the animals from each group were subjected to a high-intensity inclined treadmill running protocol, which has been previously demonstrated to induce neurotrauma. Sensory testing and radiographic analyses were periodically performed. Histopathologic analyses were performed post killing. Results: DIO mice had significantly higher bodyweights, higher body fat percentages, and lower bone mineral density than wildtype control mice that were fed a normal diet throughout the experiment (P <.001 for each). DIO mice displayed significantly reduced sensory function in week 1 (P =.005) and this worsened over time, requiring 20.6% more force for paw withdrawal by week 10 (P <.001). DIO mice that ran demonstrated greater midfoot subluxation and tarsal instability over all time points compared with normal-diet mice that ran (P <.001). Histopathologic analyses revealed that DIO mice that ran demonstrated significant changes compared with controls that ran (P <.001 for each parameter). Conclusion: Changes akin to the earliest changes observed in or before joint destruction identified in diabetic Charcot neuropathic arthropathy in humans were observed. Clinical Relevance: There is currently no standard of treatment for patients with Charcot neuropathic arthropathy. This study establishes a protocol for an animal model that can be used to study and compare interventions to treat this disease. [ABSTRACT FROM AUTHOR]

Objective: Carpal tunnel syndrome (CTS) is the most common type of entrapment neuropathy caused by compression of the median nerve in the carpal tunnel. Epilepsy is characterised by recurrent seizures caused by abnormal neuronal discharges in the brain.This study aimed to investigate whether there is a link between epilepsy and carpal tunnel and, if so, the underlying factors. Materials and methods: Two hundred patients with epilepsy were included in this study. The patients' history of epilepsy, seizure type, and seizure frequency were assessed. The Tinel, Phalen, and Flick physical examination tests were performed on patients with complaints that matched those of median nerve neuropathy. Patients with epilepsy and clinically diagnosed carpal tunnel syndrome completed the Boston Carpal Tunnel Syndrome Questionnaire, and nerve conduction studies were performed. The relationship between seizure type and frequency in patients with carpal tunnel syndrome was compared. Results: Compared to focal-aware motor-onset seizures, the risk of detecting carpal tunnel syndrome was 88.7 times higher in focal-onset bilateral tonic-clonic seizures. Patients with a seizure frequency of one per month or more had a 0.704 times lower risk of CTS than those with a frequency of one per week or more (p = 0.026). Discussion: Patients with epilepsy, especially those experiencing frequent seizures or specific seizure types, may be more susceptible to repetitive wrist flexion-extension postures. Therefore, during clinical follow-up, it is important to inquire about the presence of carpal tunnel syndrome in patients with epilepsy.

Osteochondral lesions of the talus (OLTs) are lesions that occur before the physis closes and are frequently associated with acute ankle trauma. These lesions are often difficult to diagnose due to swelling and inflammation that are present after the initial injury. A growing body of literature has assessed the effects of OLTs in the adult population. However, the literature examining these lesions in the juvenile population is sparse. The purpose of this review is to provide a thorough understanding of OLTs, with a specific focus on the juvenile population. We evaluate the recent literature regarding the outcomes of various surgical treatment; modalities in the pediatric patient. While the outcomes after surgical treatment of pediatric OLTs are generally favorable, the paucity of investigation in this demographic is alarming. Further research is needed to better inform practitioners and families regarding these outcomes, as treatment plans are highly dependent on the individual patient in question. [ABSTRACT FROM AUTHOR]

This article discusses a case of a nasal chondroma, a benign tumor of the cartilaginous tissue, that developed in a 59-year-old female patient two years after undergoing a nasal filler procedure. Nasal chondromas are rare, especially in the nose, and their exact cause is unclear, although microtrauma is believed to be a possible factor. The patient underwent surgical removal of the tumor, and histopathology confirmed the diagnosis. The article emphasizes the importance of informing patients about the potential risk of developing this tumor due to microtrauma during nasal filler procedures. [Extracted from the article]

The purpose of this article is to present the phenomenon of psychological microtrauma, a trauma that is cumulative in nature and results from prolonged exposure to many stressful situations in one area of suffering that are usually not so severe as those causing post-traumatic stress disorder and are included in criterion A in the Diagnostic and Statistical Manual of Mental Disorders. The introduction to the International Classification of Diseases 11th Revision of a new disorder named complex post-traumatic stress disorder, despite allowing a better understanding of people who experience chronically repeating traumas, does not explain the consequences of microtrauma which can be approached from psycho-dynamic, clinical and social perspectives. Taking into account the difficulties associated with identifying microtrauma, knowledge of this phenomenon could be useful for clinicians and their patients. The theory of microtrauma is a promising area of research and may finally bring the answer why there is a high prevalence of diagnosing post-traumatic disorder among people who experience not severe but chronic stressful events in one area in terms of content in their daily lives, e.g. discrimination. It shows how much is still ahead of us in understanding trauma and how rich and complex this phenomenon is. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: To evaluate the effect of micro-osteoperforations (MOPs) on the rate of orthodontic tooth movement (OTM) during en masse anterior retraction., Materials and Methods: Twenty patients were randomly allocated into experimental and control group of 10 each. In the control group, en masse retraction was performed with sliding mechanics with a coil spring. In the experimental group after alignment and levelling, MOPs were performed mesially and distally to all six anterior teeth in the interdental cortical region on the labial aspect of both arches. MOPs were performed at the beginning of space closure (T
0 ) and 1 month after beginning of space closure (T1 ). En masse retraction was performed with sliding mechanics with a coil spring. Measurements were recorded on digital models made from scanned plaster casts at the beginning of space closure (T0 ) and monthly at each follow-up visit for the next 4 months (T1 , T2 , T3 , T4 ). The monthly rate of OTM, the overall rate of OTM, and the difference between OTM in the MOP period (T0 -T2 ) and post-MOP (T2 -T4 ) period in the experimental and control group were evaluated. A visual analogue scale (VAS) was used to evaluate patients' pain experience., Results: The overall rate of OTM was significantly greater in the experimental group for both arches in the MOP period (T0 -T2 ) and also in the post-MOP period (T2 -T4 ) as compared to the control group. Within the experimental group, the rate of OTM in the MOP period was significantly greater than in the post-MOP period, which in turn was greater than that of the control group. The patients reported only mild discomfort for 24 h after performing the MOPs, which then gradually decreased., Conclusions: The use of MOPs is effective in increasing the rate of en masse tooth retraction in both the maxillary and the mandibular arch. The rate of tooth movement was greater even in the post-MOP period as compared to the control group., (© 2022. Springer Medizin Verlag GmbH, ein Teil von Springer Nature.)- Published

The young, overhead throwing athlete is prone to overuse injuries because of their variable skeletal maturity and often improper technique. An overuse injury to the digit(s) in the overhead throwing athlete, Little Leaguer's Finger, has never been discussed in the literature to our knowledge. We present a case of a 14-year-old man with atraumatic pain, swelling, and edema to his dominant pitching index finger after throwing greater than 90 pitches in one setting. Initial workup of the patient, including an MRI, ruled out an infectious process, and it was determined that there was a stress epiphysitis within the proximal phalanx of the digit. Symptoms within the digit resolved given time, rest, and cessation of throwing activities. The purpose of this report was to stress the importance of establishing the etiology of finger pain in the throwing athlete and to describe a previously unreported overuse injury, Little Leaguer's Finger.

Traumatic brain injury is a devastating public health problem, the eighth leading cause of death across the world. To improve our understanding of how injury at the cellular scale affects neural circuit function, we developed a protocol to precisely injure individual neurons within an in vitro neural network. We used high speed calcium imaging to estimate alterations in neural activity and connectivity that occur followed targeted microtrauma. Our studies show that mechanically injured neurons inactivate following microtrauma and eventually re-integrate into the network. Single neuron re-integration is dependent on its activity prior to injury and initial connections in the network: more active and integrated neurons are more resistant to microtrauma and more likely to re-integrate into the network. Micromechanical injury leads to neuronal death 6 h post-injury in a subset of both injured and uninjured neurons. Interestingly, neural activity and network participation after injury were associated with survival in linear discriminate analysis (77.3% correct prediction, Wilks' Lambda = 0.838). Based on this observation, we modulated neuronal activity to rescue neurons after microtrauma. Inhibition of neuronal activity provided much greater survivability than did activation of neurons (ANOVA, p < 0.01 with post-hoc Tukey HSD, p < 0.01). Rescue of neurons by blocking activity in the post-acute period is partially mediated by mitochondrial energetics, as we observed silencing neurons after micromechanical injury led to a significant reduction in mitochondrial calcium accumulation. Overall, the present study provides deeper insight into the propagation of injury within networks, demonstrating that together the initial activity, network structure, and post-injury activity levels contribute to the progressive changes in a neural circuit after mechanical trauma.

Degeneration of the intervertebral disk (IVD) is a pathological process resulting from an interplay between genetic and environmental factors causing structural and functional damage of the IVD and neighboring structures. It is the first stage of degenerative cascade in the vertebral motion segment. Initiation and progression of IVD degenerative processes traditionally involves several factors: inadequate mechanical load, decreased diffusion of nutrients through the arch laminae, and genetic factors playing a significant role in the development of degenerative changes. Three categories of candidate genes whose coding variants are associated with different forms of degenerative changes in the IVD are identified, a conceptual model of genetic interactions in degenerative disease of the disk is developed. The study of the role of structural changes in back pain genesis, evaluation of risk factors allow to optimize the tactics of patient care and find new therapeutic solutions preventing disease progression.

Purpose To report the results of a first-in-human study using a robotic device to assist subretinal drug delivery in patients undergoing vitreoretinal surgery for macular haemorrhage. Design Double armed, randomized controlled surgical trial (ClinicalTrials.gov identifier: NCT03052881). Methods Setting Oxford Eye Hospital, Oxford University Hospitals NHS Foundation Trust, Oxford, United Kingdom. Participants In total, 12 participants were recruited: 6 in the robot-assisted and 6 in the control manual surgery arm according to the pre-specified inclusion and exclusion criteria. All subjects presented with acute loss of vision due to a sub-foveal haemorrhage secondary to neovascular age-related macular degeneration. Intervention After standard vitrectomy, intraoperative OCT-guided subretinal injection of tissue plasminogen activator (TPA) was performed either by robot-assisted or conventional manual technique under local anaesthesia. The robotic part of the procedure involved advancement of a cannula through the retina and stabilizing it during foot-controlled injection of up to 100µl of TPA solution. Main Outcome Measures We assessed surgical success, duration of surgery, adverse events, and tolerability of surgery under local anaesthesia. Results The procedure was well tolerated by all participants and safely performed in all cases. Total duration of surgery, time taken to complete the injection and retinal microtrauma were similar between the groups and not clinically significant. Subretinal haemorrhage was successfully displaced at 1-month post-intervention, except for one control subject, and the median gain in visual acuity was similar in both arms. Conclusions This first-in-human study demonstrates the feasibility and safety of high precision robot-assisted subretinal drug delivery as part of the surgical management of sub-macular haemorrhage, simulating its potential future application in gene or cell therapy.

28. The anti-inflammatory effect of acupuncture and its significance in analgesia.

Jin, Bonnie Xia, Jin, Louis Lei, and Jin, Guan-Yuan
- Abstract
In the mechanisms of acupuncture analgesia, an important aspect often overlooked is the anti-inflammatory effect of acupuncture, which is mainly attained through the self-limiting inflammatory response-inflammatory reflex and its regulation of hypothalamic-pituitary-adrenal(HPA) axis and autonomic nerve system (the vagus nerve and the sympathetic postganglionic fiber). The significance of anti-inflammatory effect of acupuncture in analgesia is manifested twofold: The first, inflammatory nociceptive pain is a major type of chronic pain. The second, neurogenic inflammation is the mechanism by which certain acupoints or acu-reflex points (ARPs) are formed at the body surface and have short-cut connections to the pathological focus. Selecting ARPs and applying appropriate sensory stimulation or local microtrauma (affected by different needling means or stimulation parameters), combined with low-frequency electrical stimulation or the vagus stimulation in the concha region, are helpful to strengthen the anti-inflammatory and analgesic effect of acupuncture.

Work-related diseases of the musculoskeletal and the peripheral nervous system are classified as overload cumulative microtrauma diseases, resulting from chronic overload and/or damage of specific neuromusculoskeletal structures. Occupational activities which predispose to them are characterised by monotypy (repetition of movements during a significant part of the working shift). Authors described 4 cases of women with musculoskeletal and peripheral nervous system disorders qualified as occupational background just in the 2nd instance of medical certification. Detailed analysis of occupational exposure and medical interview with individual diagnostic approach allowed to determine the occupational etiology of diseases, regardless of non-occupational risk factors in some cases, even if the workstation was not common. Difficulties in estimating the probability of disease process induction on the background of occupational exposure are caused by frequent coexistence of non-occupational risk factors. The 2-tier system of certification provides an independent evaluation of medical history and occupational exposure. Med Pr. 2022;73(1).

Background Osteochondritis dissecans (OCD) is considered to show the following stages of pathological progression: IA, nearly normal-cartilaginous; IB, deteriorated-cartilaginous; IIA, cartilage-ossifying; and IIB, cartilage-osteonecrotic. However, the validity of this pathological staging for OCD has yet to be confirmed in a large number of cases. Purpose The aim of the present study was to confirm the clinical validity of the proposed pathological staging of OCD. Methods The subjects were 74 patients (mean age, 14.2 years; mean skeletal age score, 25.6 points) with capitellar OCD. Partially detached articular fragments were surgically removed, and were examined histologically. The articular fragments were independently assessed by five observers and the reliability of assessment was examined. The correlation between the pathological stages and the clinical data was analyzed. Results The reliability of the assessment among five observers was almost perfect. OCD stages of IA, IB, IIA, and IIB were evident in eight, 36, 10, and 20 patients, respectively. OCD-I (cartilaginous) and OCD-II (osteochondral) corresponded significantly to radiographic stage I (radiolucency) and stage II (delayed ossification), respectively. The pathological OCD stages were significantly correlated with the clinical data, including the period from symptom onset to surgery, patient age, and the skeletal age score (p Conclusion Our results confirmed that the proposed pathological staging of OCD corresponds to the observed clinical progression of OCD, thus validating the staging system. Our findings revealed that OCD begins with separation beneath the epiphyseal cartilage which is programmed to be replaced with bone. When a stage IA articular fragment has remained partially detached for a prolonged period, the epiphyseal cartilage may be deteriorated and become degenerated, and subsequent ossification may not occur, as is evident in OCD-IB. In contrast, stage IA with a vascular supply through the fibrocartilaginous connection can progress to stage IIA. During the prolonged period in which the osteochondral articular fragment remains un-united, microtrauma can cause to disturb the blood supply to the bony fragment, resulting in osteonecrosis (stage IIB).

In animal models, there was observed alteration of various physiological processes caused by microtraumas. Here reported experiment was aimed on the research of link between injection and development of an oxidative imbalance. Laboratory guinea pig was chosen as a suitable model for examining of the oxidative stress. Markers indicating oxidative homeostasis were assayed in the frontal, temporal and occipital brain lobe, cerebellum, liver, kidney, spleen and heart one hour after an intramuscular injection. Common biochemical parameters were measured in plasma samples as well. The most extensive effect was observed in the heart where the thiobarbituric acid reactive substances value was more than twice increased after the injection. The level of carbonylated proteins was significantly elevated in the kidney and ferric reducing antioxidant power value was increased in the brain compartments. The enzyme activities in the organs were not influenced except the activity of superoxide dismutase, which was moderately decreased in the brain. In the plasma samples, there was observed increase of the blood urea nitrogen. The results showed significant the influence of the intramuscular injection on a development of an oxidative insult. The injection can be considered as an adverse effect with quite extensive stress consequences.

The reasons for the development of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) have recently been quite a popular topic. The main interest is among plastic surgeons, surgical oncologists, hematologists, and oncologists. Over the past decade, numerous scientific papers on this subject have been published. Potential etiopathogenetic factors include the type of implants, biofilm, inflammation, microtrauma, and genetic mutations. None of the above potential causes have been adequately proven by scientific evidence; anyway, they should not be considered separately, as they are likely to coexist. Further research and exchange of experience among doctors and scientists are necessary to determine the leading etiopathogenetic factor. Its emergence would contribute to the rise of the possibility of using effective preventive measures in patients undergoing breast implant surgery and perhaps even eliminating BIA-ALCL.

Background: Frozen Shoulder is a painful shoulder condition with insidious onset that was associated with stiffness and loss of motion in the shoulder joint. Mulligan Mobilization with Movement for shoulder joint combines sustained manual application of ‘gliding’ force to a joint, with the aim of repositioning the positional faults with concurrent physiological motion of the joint. Kinesiotaping improves glenohumeral motions and reduces microtrauma and mechanical irritation of soft tissue structures and reorient shoulder movements through arc of improved glenohumeral motion. Objective: To compare effect of Mulligan Mobilization with Movement and Kinesiotaping on pain and active shoulder range of motion using VAS and universal goniometer. Method: 30 subjects were selected as per inclusion and exclusion criteria and were randomly allocated into 2 groups of 15 each. Group A received Mulligan Mobilization with Movement and Group B received Kinesiotaping for shoulder joint. Pre and Post intervention shoulder external rotation, abduction and internal rotation range of motion and VAS scores were analysed. Result: The statistical analysis showed that there is a significant increase in range of motion and significant reduction in pain scores post intervention in both the groups (p

Background Overuse injuries result from the cumulative process of repetitive microtrauma and overload on the musculoskeletal system, which causes tissue damage. Therefore, these injuries may have long-term negative consequences that decrease an athlete's performance. Objective To estimate the prevalence of overuse injuries in individual and team sports. Methods Searches on MEDLINE, EMBASE, SPORTDiscus, and CINAHL from the first registration to February 2021 and hand-searching identified studies investigating the prevalence of overuse injuries in athletes from individual and team sports. Meta-analysis was conducted and the GRADE system summarized the overall quality of evidence. This review was registered in PROSPERO (CRD42019135665). Results Seventeen studies were included and pooling of 24 704 participants (22 748 of individual sports and 1.956 of team sports). Data from point- and period-prevalence of overuse injuries in individual and team sports were obtained. Pooled period-prevalence of overuse injuries in individual and team sports was 42.0% (95% CI: 30.0, 55.0) and 33.0% (95% CI: 21.0, 49.0), respectively. Another four studies investigated point-prevalence. The overall quality of evidence for the period-prevalence was of moderate quality. Sensitivity analyses suggested that different joints based in individual and team sports tended to increase the estimated prevalence of overuse injuries. Conclusion Athletes, clinicians, sport teams, and policymakers should be aware of the high prevalence of overuse injuries in athletes, especially, in athletes from individual sports. Current moderate-quality evidence shows that future high-quality studies are likely to impact on the estimated prevalence.

Neuropathic arthropathy of the knee (Charcot knee) is a rare pathology defined by progressive destruction of bone and soft tissue in a patient with underlying peripheral neuropathy. Historically, Charcot knee was associated with neurosyphilis, but it has been increasingly described as a late stage of diabetes. The pathophysiology of the disease is not completely understood, but theories include repetitive microtrauma and an abnormal neurovascular response. Patients present with a warm, swollen, and unstable joint and have rapid bone resorption and characteristic findings on pathology. Nonsurgical options for pain and dysfunction include total contact casting and bracing treatment. Pharmacologic management includes diphosphonates, although this use is considered off-label. Surgical management historically included knee fusion. However, recent case series have suggested that newer prostheses allow for successful arthroplasty in this cohort, although complications are higher when compared with joint arthroplasty in patients with normal neurologic function.

Achilles tendinopathy is a common overuse condition that is characterized by degenerative, cumulative tissue microtrauma. It is largely a clinical diagnosis in which the patient typically presents with localized pain that is worse with tendon-loading activities. Imaging modalities may be helpful with the diagnosis of difficult cases or in the planning of interventional procedures. Midportion (noninsertional) and insertional tendinopathy have distinct features and differences for therapeutic paradigms. Overall, Achilles tendinopathy has a good clinical prognosis with most patients improving with activity modification and rehabilitation, with a focus on progressive tendon-loading. Recalcitrant cases may require adjuvant treatment with procedures (e.g., injections, shockwave therapy) and rarely surgical intervention.

Osteoarthritis (OA) is a degenerative disease that can manifest in any synovial joint under certain conditions. It leads to destruction of articular cartilage and adjacent bone, as well as formation of osteophytes at the edges of afflicted joint surfaces. Regarding the wrist, typical degenerative arthritis affects particular joints at a specific patient age, due to asymmetric load distribution and repetitive microtrauma. However, in the presence of instability or systemic diseases, early-onset degeneration can also impair the range of motion and grip strength in younger patients. Although advanced stages of OA display characteristic signs in radiography, the detection of early manifestations frequently requires computed tomography or magnetic resonance imaging (in some cases with additional arthrography). If a wrist becomes unstable, timely diagnosis and precise treatment are essential to prevent rapid disease progression. Therefore, close collaboration between radiologists and hand surgeons is obligatory to preserve the carpal function of patients.

Pain in the lower abdomen and groin can occur in athletes who perform sharp lower extremity movement during training or sports, make sharp turns and change direction of the trunk movement as well as lower extremity acceleration/deceleration. An excessive load during the sports game can disturb the biomechanics of the player's movements. A precise localization of damaged tissues can improve for the diagnosis, determining treatment and forecasting the time of return to sports. The aim was to estimate the importance of the football biomechanics movement for the anatomy of the groin and to determine the anatomical features of the groin in football players with sports hernia. We analysed the thickness and length measurements on MRI of the rectus abdominis muscle in 51 football players of professional and amateur clubs aged 17 to 33 years with groin pain who were treated at the Kyiv Clinical City Hospital №3 for the period 2014-2020. In the second stage of the study, we investigated the peak force of the abdominal muscles (rectus abdominis, external oblique abdominal muscles) and the adductor muscles of both lower extremities using the microFET2 dynamometer for 4 groups of football players. The first group of the study includes 15 football players of professional clubs with sports hernia who had received conservative treatment, the partipants of the second group are 36 football players after laparoscopic hernioplasty, the third group consisted of 54 healthy young football players and 11 teenage footballers. In the third stage of the study, a formula was substantiated, according to which we calculated the acceleration of the lower extremity when kicking the ball. The results of the study demostrate that the disruption of the lower extremity biomechanics during kicking the ball cause the appearance of sports hernia in football players. An axial MRI scan of groin areas of football players with sports hernia represented changes in the lateral edge of the rectus abdominis. The groin pain syndrome of football players with sports hernia includes three pathogenetic mechanisms of development: disruption of the biomechanics, muscle imbalance and microtrauma and inflammation.

Ankle impingement refers to a chronic painful mechanical limitation of ankle motion caused by soft tissue or osseous abnormality affecting the anterior or posterior tibiotalar joint. Impingement can be associated with a single traumatic event or repetitive microtrauma. These syndromes are a possible etiology of persistent ankle pain. An arthroscopic approach to this pathology, when indicated, is considered as ideal treatment with its high safety and low complication rate. We describe the clinical and potential imaging features, and the arthroscopic/endoscopic management strategies, for the 4 main impingement syndromes of the ankle: anterolateral, anterior, antero-medial, and posterior.

Background Supraspinatus tendon is a part of the rotator cuff of the shoulder, partial or full-thickness tear can affect the tendon secondary to trauma or repeated microtrauma. The aim of the present study is to evaluate the efficacy of platelet-rich plasma (PRP) injection in comparison to physical therapy for treatment of chronic partial supraspinatus tears. Results At the beginning of the study, there were no significant differences between both groups in all parameters: (a) PRP injection had significantly improved the visual analog scale (VAS), disabilities of arm, shoulder and hand scale (DASH) and shoulder range of motion (ROM) but not size of tear at 6 and 12 weeks post-injection in comparison to baseline recordings; (b) physical therapy had significantly improved VAS, DASH but not shoulder ROM nor size of tear at 6 and 12 weeks post-injection in comparison to baseline recordings; and (c) PRP injection was superior to physical therapy in the improvement of VAS, shoulder ROM, and DASH score. Conclusion The US-guided PRP injection is superior to physical therapy in improving pain, ROM, and function in treatment of partial thickness tear of supraspinatus tendon.

Introduction: Preferred sites of osteochondritis dissecans (OCD) are the distal femur and humerus, and the dome of the talus. We report a rare case of a professional soccer player with bilateral OCD of the talar posterior calcaneal articular surface. Case Report: The left talus showed a loose but not displaced fragment, and pain was relieved with 3 months of conservative treatment. The right had two loose fragments that were displaced from their beds in the talar posterior calcaneal articular surface. The loose bodies were surgically excised. The player remains symptom free 4 years after the operation and participates in professional games. Thus, although OCD of the talar posterior calcaneal articular surface remains a relatively uncommon injury, we suggest that treatment methods tailored to the OCD stage as per Berndt and Harty classification may be successful. The exact causes and establishment of a treatment protocol in these cases will depend on the investigation of future cases. Conclusion: Since this case of OCD of the talar posterior calcaneal articular surface was bilateral, we hypothesized that it may have been caused by microtrauma in the sense of repetitive, excessive compression of the subchondral bone, or by a vascular etiology. Keywords: Case report, lateral hindfoot pain, osteochondral lesion, subtalar articular facet, subtalar joint.

BackgroundEpidermolysis bullosa (EB) comprises a heterogeneous group of rare genetic diseases associated with skin blistering caused by minimal trauma. A major and common EB subtype, recessive dystrophic EB (RDEB), is characterized by altered wound healing, inflammatory dysbalance and fibrotic changes associated with reduced to absent collagen VII. Because of its exposed position and its continued use in daily activities, the hand is constantly at risk of microtrauma and is therefore one of the organs most affected by the disease with highly disabling deformities that represent a challenging field in hand surgery practice.MethodsThe authors present their experience in the microsurgical treatment of pseudosyndactylies comparing the classic dressing with vaseline gauze with an innovative “glove protocol” using Integra®dermal regeneration template. The endpoints analyzed were: healing times, hospital stay time, discomfort for the patient, free-recurrence interval, follow-up range and major complications.ResultsA total of 34 procedures were performed on 24 RDEB patients with hand deformities. Compared with the dressing with vaseline gauze, microsurgery followed by application of dermal regeneration template gloves allowed a significant reduction of hospital stay, healing time, and dressing pain as well as an increased recurrence-free interval.ConclusionsThe microsurgical approach followed by our new protocol described in the study has been beneficial in providing consistent and successful long-term results for these patients.

Background: Adenomyosis (AM) uteri exhibit hyperperistalsis. The latter causes a chronic tissue trauma at the endometrial–myometrial junctional zone (EMJZ). Upon tissue trauma, microdehiscences in the myometrium facilitate the translocation of basal endometrial fragments into the myometrium. There, a metaplasia (mediated by transforming growth factor β1 [TGFβ1] and connective tissue growth factor [CTGF]) occurs and AM lesions develop. The abundance of myofibroblasts in a tissue hallmarks metaplasia and points to a tissue microtrauma. Materials and Methods: To study if myofibroblasts—as an evidence of tissue microtrauma—are more abundant at EMJZ in AM-uteri, a case–control experimental study was carried out at Charité University Hospital—Endometriosis Research Centre. In all, 18 uteri with AM and 14 uteri without AM were obtained during laparoscopy-assisted vaginal hysterectomy. The immunolabeling of myofibroblastic metaplasia (alpha smooth muscle actin [ASMA] and collagen I), differentiated smooth muscle marker (desmin) and metaplasia mediators (TGF-β receptors 1, 2, 3 and CTGF) was investigated. The ultrastructure of myofibroblasts at EMJZ of AM uterus was characterized by transmission electron microscopy, in addition to an in vitro study to characterize myofibroblasts in the endometrium of non-AM uterus. Results: Immunolabeling of ASMA and collagen I was significantly higher at EMJZ of AM uteri versus non-AM uteri. Furthermore, myofibroblasts were ultrastructurally characterized at EMJZ of AM. Endometrium of non-AM uterus exhibited 5% to 8% of its cells, expressing ASMA and collagen I. No difference was noted regarding metaplasia mediators immunolabeling between both the groups. Conclusion: The abundant and persistent myofibroblasts (expressing ASMA/collagen I) at EMJZ in AM uteri are ultra-/microscopic evidence of chronic tissue trauma. They are of nonmyometrial origin, as they lack desmin immunolabeling. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Sports injuries occur during sport athletic activities, or exercising. However, there are some lesions which are typically associated to sports, in such a demanding and physical sport like Muay Thai that no typical lesion has been detected yet. We performed a narrative review of the literature to highlight the typical lesions of this sport to analyze the differential diagnosis of those conditions., Case Report: A 28-year-old female, Muay Thai athlete since 16 years, presented with a 6 months history of a persistent pain in the metaphyseal lateral part of the right tibia. Differentiation between stress injuries, malignant bone tumors, and tumor-like lesions after repetitive microtrauma following sport activities can be difficult. The diagnostic approach involved conventional X-ray, echotomography, computed tomography scan, and magnetic resonance imaging scan with controversial findings. The biopsy confirmed the final diagnosis of non-ossifying fibroma., Conclusion: The purpose of this case report is to exhibit the challenges in the diagnosis of a professional Muay Thai athlete with tibial pain and to discuss the clinical presentation of this type of patients with a limited population in the literature. Our case illustrates that even modern imaging techniques cannot always distinguish between tumor and tumor-like lesions caused by sports; meanwhile remembered us that we should never be too focused on a particular characteristic forgetting even rare pathologies as adamantinoma., Competing Interests: Conflict of Interest: Nil, (Copyright: © Indian Orthopaedic Research Group.)

- Abstract
Plexiform neurofibroma is a rare benign tumor and a special subtype of neurofibromatosis 1. This report is a literature review with a case of patient with facial hemorrhage observed at the site of neurofibroma removal in the right lower face due to minor trauma. Through PubMed search, using terms ((facial hematoma) OR (facial bleeding)) AND (neurofibromatosis), 86 articles were identified, and five related articles (six patients) were finally selected. Of the six patients, two had previously undergone embolization. However, as a result, all patients received open surgery to remove hematomas. The hemostatic methods mentioned were vascular ligation (five patients), hypotensive anesthesia (two patients), and postoperative blood transfusion (four patients). In conclusion, spontaneous or minimally traumatic bleeding is possible in neurofibromatosis patients. In most cases, it can be resolved by vascular ligation under hypotensive anesthesia. Optionally, prior embolization and supplementary tissue adhesive may be used.

Knee injuries, acute or chronic are one of the most often injuries in sport, both in adults and adolescents. They mostly occur in contact sports due to torsional and decelaration forces, causing around 80% painful knee conditions that disable sports performance. If chronic, they occur in the form of repetitive microtrauma that generates articular cartilage damage, producing cartilage softening and thinning and causing anterior knee pain. Etiological factors that are also associated with anterior knee pain in the form of patellar chondromalacia are idiopathic or post-traumatic patellar luxation and different types of femoral trochlear dysplasia. Repetitive trauma might cause cartilage fissures, fragmentation and necrosis so the patients can feel retropatellar pain, ussually after physical activities. Treatment of patellar chondromalacia is usually conservative but an early diagnosis (magnetic resonance imaging and arthroscopy) is essential in the prognosis of these patients.

The chronic sequelae of Stevens-Johnson syndrome cause severe ocular morbidity. Among the various manifestations, including dry eye, cicatrization causing forniceal shortening, adnexal disorders, lid margin keratinization, and limbal stem cell deficiency, keratinization of the lid margin leads to progressive ocular surface damage through constant blink-induced microtrauma. This damage induces corneal punctate keratopathy and neovascularization and can produce epithelial defects leading to corneal infection or perforation. Management strategies for chronic ocular sequelae are broadly categorized into ocular surface stabilization procedures, tectonic procedures, and visual rehabilitation procedures. Interventions in the acute stage of the disease include amniotic membrane grafting. Timely intervention helps to prevent deterioration of the ocular surface in these eyes.
