“…Distal MTJ injuries were pointed out as common [9], more recurrent and severe, and requiring longer rehabilitation [9,10]. Reasons for higher stiffness in the injured legs compared with the controls might be explained by potential scarring of tissue around the injury location [24,26,[30][31][32][33][34]. Tissue changes (i.e., mechanical properties) would affect the passive tension and stiffness of the BFlh structure towards higher values [86].…”

“…Moreover, it is documented in the literature that hamstring muscle stiffness results may be influenced by age [88,89], genetics [88,90], sex [91], sports profession [39,92], pelvic tilt type [93], hip and knee positions [94], injury and scar status [32][33][34], and operator of the shearwave elastography [95]. Besides reasons based on the characteristics and history of the…”

“…Therefore, this study aimed to compare the BFlh fascicle length via the EFOV technique, passive stiffness of the mid-belly and MTJ of the BFlh via ultrasound-based shear wave elastography between previously injured legs and uninjured contralateral legs of athletes with HSI history, and both legs of athletes without HSI history. The hypotheses of this study were considered as follows: 1) previously injured legs will have shorter fascicles in the BFlh compared to contralateral uninjured legs and both legs of the athletes without HSI due to possible decreased exertion at the beginning of rehabilitation [22], reduced involvement in sports [24], and/or neural inhibition after the HSI [24][25][26][27][28][29]; 2) previously injured legs will have higher stiffness in the BFlh after the injury compared with contralateral uninjured legs and both legs of the athletes without HSI due to possible contractures or scars in the muscle [24,26,[30][31][32][33][34][35].…”

Introduction Hamstring strain injuries (HSI) and re-injuries are endemic in high-speed running sports. The biceps femoris long head (BFlh) is the most frequently injured muscle among the hamstrings. Structural parameters of the hamstring muscle are stated to be susceptible to strain injuries at this location. This retrospective study targeted comparing the BFlh’s structural parameters between previously injured and uninjured athletes. Methods Nineteen male athletes with previous BFlh strain injury history and nineteen athletes without former lower extremity injury history were included in this study. Fascicle length, mid-muscle belly and distal musculotendinous (MTJ) passive stiffnesses of the biceps femoris long head (BFlh) were examined via b-mode panoramic ultrasound scanning and ultrasound-based shear-wave elastography. Parameter comparisons of both legs within and between athletes with and without injury history were performed. Results Comparison of the BFlh fascicle length between the injured leg of the injured group and the legs of the controls revealed a trend to shorter fascicle lengths in the injured leg (p = 0.067, d = -0.62). However, the mid-muscle belly passive stiffness of the BFlh was significantly higher in the injured legs (p = 0.009, d = 0.7) compared with the controls. Additionally, the distal MTJ stiffness was much higher in the previously injured legs compared with controls (p < 0.001, d = 1.6). Conclusions Outcomes support the importance of BFlh properties related to stiffness, and fascicle length for injury susceptibility in athletes. Future prospective studies should determine whether the higher stiffness in the injured athletes is a cause or consequence of the HSI. Physical therapy and rehabilitation programmes after HSI should focus on BFlh muscle properties i.e., elasticity and fascicle length for reducing re-injury and increasing sports performance.

“…This means that some patients may not have access to this technology or may need to travel to specific clinics to have an SWE assessment of their scars. 18 Three-dimensional (3D) topography 3D systems can reflect the scar surface characteristics with high definition and reproducibility. One system, the Antera3D® camera provides an objective, noninvasive, longitudinal system to detect and record changes in scar morphology and through surveilling haemoglobin change, which strongly correlates to both responses to treatment and the recurrence probability.…”

Keloids are an exaggerated response to cutaneous trauma that has both a physical and psychological burden for patients. Keloids have high recurrence rates and are monitored years after treatment. There is currently no widely accepted assessment measure specifically for keloids. The purpose of this review was to compare available assessment measures for keloids. Eleven assessment measures were assessed based on validity, reliability, limitations, parameters, technological influence and feasibility. Only two assessment measures (Detroit Keloid Scale and the Keloid Area and Severity Index) were specific for keloids, easy to use, had no cost and were suitable for longitudinal use. These measures, in conjunction with quality of life measures such as the Dermatology Life Quality Index, could be used to provide a detailed and longitudinal assessment of keloid treatment.

“…Ultrasound imaging is a noninvasive imaging modality that provides real-time information on tissues. High-frequency ultrasound (HFUS) is advantageous for the high-resolution imaging of tissues within a limited penetration depth; for example, it is advantageous for imaging skin and eye tissues and for imaging small animals. − Both single-element and array transducers have been used for two-dimensional B-mode imaging and Doppler imaging . Over the past few years, scientists have begun using sonography to predict the infection of surgical wounds.…”

Multifunctional Hydrogel Dressing That Carries Three Antibiotics Simultaneously and Enables Real-Time Ultrasound Bacterial Colony Detection

We have developed a multifunctional hydrogel that can carry three synergistic antibiotics commonly used in clinical practice. This hydrogel was discovered to have drug encapsulation efficiencies of 94% for neomycin, 97% for bacitracin, and 88% for polymyxin B. Drug release data indicated that the release profiles of these three antibiotics were different. A swelling test demonstrated that the hydrogel absorbed liquid after the release of its antibiotics until it became saturated, which occurred within 48 h. Moreover, this hydrogel exhibited excellent antibacterial effects against Escherichia coli and Pseudomonas aeruginosa and biocompatibility; it can thus protect a wound from microbial invasion. When the alginate hydrogel is used to cover a wound, the wound can be checked for colonization at any time using ultrasound imaging; this can thus enable the prevention of wound biofilm formation in the early stages of infection. We evaluated the hydrogel against commercially available wound dressings and discovered that these wound dressings did not have the aforementioned desirable features. In conclusion, our multifunctional hydrogel can carry three types of antibiotics simultaneously and is a suitable medium through which an ultrasound can be performed to detect the growth of colonies in wounds. The hydrogel is expected to make a valuable contribution to the prevention of wound infections in the future.
