Summary: Chronic ankle instability (CAI) can arise from functional (FAI) and mechanical ankle instability (MAI). Assessing the mechanical instability quantitatively remains a challenge, with methods like stress sonography and 3D stress MRI showing promise. Manual stress testing is valuable but subjective, with a need for more objective alternatives for diagnosing MAI.

Summary: The study tested the efficacy of a semirigid ankle brace on joint congruency using a novel 3D stress-MRI technique. The application of the brace led to an increase in cartilage contact area in plantarflexion and supination, but did not correlate with the perceived stability provided by the brace.

Summary: Chronic ankle instability is caused by mechanical, functional, and perceived factors. It is important to assess the dominant factor in causing impairment in order to make appropriate therapeutic recommendations. Quantifying mechanical ankle instability is challenging, but thorough analysis and diagnosis are necessary. Conservative management is the standard of care, but mechanical therapy may be needed for patients with a certain degree of instability that cannot be compensated for by functional training.

Summary: The study found that ankle stress radiographs have good interobserver reliability in patients with chronic lateral ankle instability, but their consistency is not ideal. Therefore, surgeons need to exercise caution when deciding whether to operate on patients based on a single ankle stress radiograph.

Summary: Despite the extensive research on chronic ankle instability, there is still no consensus on a clear objective definition for pathological mechanical lateral ankle instability. The studies revealed a wide range of differences in arthrometric devices and measuring methods, highlighting the need for standardization in testing and measuring methods to achieve an objective definition of mechanical ankle instability.

Summary: The study found significant differences in the position of the fibula and talus between patients with mechanical ankle stability and those with functional ankle stability, with no significant differences between the latter and healthy volunteers.Increased malleolar talus index may serve as a new indirect MRI sign for identifying patients with functional and mechanical ankle instability.

Summary: The study investigated the reliability and sensitivity of the Ankle Inversion Discrimination Apparatus for Landing (AIDAL) in assessing ankle proprioception, finding good test-retest reliability for both CAI and non-CAI groups. The results showed a significant correlation between AIDAL scores and CAIT scores, indicating its potential for evaluating outcomes of CAI rehabilitation.

Summary: Chronic ankle instability is a common condition after acute ankle sprains, causing loss of function, decreased postural control, strength deficit, and reduced range of motion. The validation of FAAM and FAOS in assessing muscle strength, postural control, and range of motion in adults with chronic ankle instability was investigated in this study.

Summary: This systematic review examined 16 studies involving 872 patients and found significant anterior displacement and internal rotation of the talus in CAI ankles, with low evidence. However, there was no consensus on fibular alignment or foot posture. Further research is needed to clarify the characteristic foot and ankle malalignment in CAI for the development of efficient interventions.

Summary: Ankle joint instability after acute lateral ankle sprain is an important factor for treatment decisions, but the use of ankle joint mechanical instability as a criterion for clinical decisions is unclear. This study examined the reliability and validity of an Automated Length Measurement System (ALMS) in ultrasonography for real-time measurement of anterior talofibular distance. The results show that ALMS has excellent reliability, comparable measurement values to manual methods, and the ability to detect differences in joint distances. ALMS can standardize and simplify ultrasonographic measurements without human error in clinical applications.

Summary: Chronic ankle instability (CAI) is a common condition that may develop after an ankle sprain. Functional electrical stimulation (FES) of the peroneal muscles can induce adaptations in ankle kinematics during gait and potentially be used as a treatment for individuals with CAI.

Summary: The aim of this study was to investigate the test-retest reliability, discriminant validity, and convergent validity of a new device for measuring ankle inversion proprioception during walking. The results showed that the device had good reliability and validity in individuals with and without chronic ankle instability (CAI), and could be used as a clinical assessment tool to distinguish CAI from non-CAI individuals.

Summary: The article discusses different types of enlarged prostate, some of which are correlated with the severity of symptoms. Different types of prostatitis and possible imaging findings are highlighted, with abscesses being mentioned as a severe complication. Utricular cysts are the most common congenital anomalies of the prostate, while anomalies such as aplasia, hypoplasia, and ectopia are rare disorders.

Summary: This study aimed to evaluate the extent of solid organ manifestations in newly diagnosed inflammatory rheumatic disease (IRD) patients and present a structured systematic organ screening algorithm. The results showed that one-half of the patients had solid organ involvement at initial diagnosis of IRD, contrary to what has been reported in the literature. Therefore, systematic organ screening is crucial for treatment decisions in IRD patients.

Summary: This study compared non-standardized free text reporting (FTR) with reporting based on iRECIST in patients with metastatic renal cell carcinoma (mRCC). The moderate agreement between FTR and iRECIST suggests the need for standardized radiological assessment in clinical practice. Additionally, it was found that new lesions were frequently not recognized when using FTR, if they had already been identified in the prior follow-up examination.

Summary: This study compared the image quality and radiation exposure of three different imaging modalities, including high-class CT, mid-class CT, and cone beam CT, in infants. The results showed that high-class CT had the lowest dose but the worst image quality, while cone beam CT had the best image quality but the highest radiation exposure. Mid-class CT was in between. Based on the results, high-end CT should be used for surgical planning, while cone beam CT should be considered for cases requiring the highest image quality.

Summary: This study analyzed the changes in iron signal and exercise capacity in chronic heart failure patients before and after intravenous iron therapy. The findings showed that patients with iron deficiency had lower iron content in the spleen, liver, and heart. After intravenous iron therapy, the iron content in the left ventricle, spleen, and liver increased. Improvement in exercise capacity was associated with an increase in hemoglobin levels after intravenous iron therapy.

Summary: This study aimed to develop a predictive model for lymph node metastasis (LNM) in patients with intrahepatic cholangiocarcinoma (iCC) using computed tomography (CT) features. The study found that an LN short axis diameter of ≥ 9 mm had the highest predictive power for LNM. Additionally, the presence of intrahepatic metastasis, hilar tumor infiltration, and tumor growth along the liver capsule were identified as significant imaging features in the predictive model.

Summary: The study investigated the contamination of the working environment with paclitaxel drug-coated balloon (DCB) angioplasty due to the loss of paclitaxel containing particles from the coating during DCB preparation, insertion, and inflation. It was found that the removal of the protective cover already leads to a significant loss of paclitaxel and paclitaxel-coated surfaces in some DCB types.
