Musculoskeletal neoplasms include tumors arising from bone, cartilage, muscles, tendons, nerves, and synovium. After initial screening radiographs, magnetic resonance (MR) imaging is the mainstay of management, and its role continues to increase in both pre- and post-operative evaluations. This article presents a review of the available qualitative and quantitative MR techniques for evaluating musculoskeletal neoplasms, including conventional and advanced imaging techniques such as diffusion-weighted and diffusion-tensor imaging, chemical shift and Dixon imaging, dynamic contrast-enhanced MRI, neurography, and spectroscopy. After reading the article, radiologists and oncologists will be able to apply these principles in their practices to benefit patients with musculoskeletal neoplasms.Image-guided core needle biopsy of musculoskeletal lesions can be challenging due to a variety of technical, patient-related, and lesion-related factors. Poor preprocedural planning can result in low diagnostic yield, misdiagnosis, delay in care, and the need for additional procedures. Furthermore, suboptimal procedural technique may place the patient at an increased risk of iatrogenic complications. Optimizing pre-procedural planning by considering potential complications is important in ensuring a safe and successful procedure. We provide a review of strategies for troubleshooting challenging image-guided musculoskeletal tumor biopsies.Radiologists frequently encounter solitary bone lesions in daily practice. The interpreting radiologist has the onus to determine the level of suspicion and appropriate next-step recommendations to aid in timely healthcare decisions. Lesion imaging characteristics in conjunction with patient history and demographics ultimately determine if a bone lesion is benign. Lesions that cannot be confidently disregarded as benign and clinically insignificant require further evaluation through additional imaging, tissue sampling, or both. We review a diagnostic imaging approach to solitary bone lesions with case examples that detail real-world thought processes for interpretations and practical next-step recommendations.Tumors of the peripheral nervous system can range from benign, such as neurofibroma or schwannoma, to malignant peripheral nerve sheath tumors (MPNSTs). Magnetic resonance neurography (MRN) enables the distinction of benign peripheral nerve sheath tumors (PNSTs) from MPNSTs. In addition, MRN allows for the assessment of anatomical extent if operative management is planned and can help determine a surveillance strategy. Occasionally, tumor mimics such as traumatic neuromas can masquerade as peripheral nerve tumors. This review will illustrate the spectrum of peripheral nerve tumors and their mimics, emphasizing key distinguishing features to provide optimal MRN interpretation that enhances diagnostic thinking and therapeutic management.Imaging plays an essential role in diagnosing and managing musculoskeletal soft tissue masses. It provides anatomic details and aids in the characterization and prognostication of tumors. Advanced imaging is also essential for assessing treatment response and post-treatment surveillance. Several novel imaging techniques are now available that provide additional functional and metabolic information about these tumors. This additional information may be used to predict the biological behavior of the tumors and effectively assess the treatment response for optimizing their management. This article focuses on multiparametric imaging evaluation of soft tissue masses with a discussion of advancements in the domains of ultrasound, MRI, and CT imaging and how these may be helpful in pre- and post-treatment assessment of soft tissue tumors. Current perspectives on the role of diffusion imaging, perfusion imaging, and MR spectroscopy have been highlighted, and future directions of metabolic imaging are briefly outlined. As these advances hold a promising role in the multidisciplinary management of soft tissue sarcomas, it is important for the radiologist to be familiar with the latest advances and developments in imaging soft tissue tumors.Chronic recurrent multifocal osteomyelitis is a rare noninfectious inflammatory bone disease diagnosed based on the synthesis of clinical, radiological, and pathological findings. The differential diagnostic considerations are led by multifocal infectious osteomyelitis and multifocal neoplasms. We report a case of a 9-year-old girl who emergently presented with worsening back pain, inability to walk, and normal vital signs. C-reactive protein and erythrocyte sedimentation rate were elevated, whereas the white blood cell count was normal. Initial radiographs and MRI of the spine showed multiple edematous vertebral body lesions. Subsequent whole-body MRI demonstrated multiple additional edematous bone lesions in the right half of the body, including the scapula, femur, and tibia. The lack of symmetrical bone lesion distribution indicated image-guided percutaneous core biopsy to exclude neoplastic disease. Pathological examination of an osseous core biopsy specimen showed a noninfectious osteomyelitis pattern with no findings of Langerhans cell histiocytosis, malignancy, or infectious osteomyelitis. The synthesis of clinical, radiological, and pathological findings was diagnostic of asymmetric right-sided chronic recurrent multifocal osteomyelitis, representing an atypical presentation that deviates from the typically symmetrical bilateral chronic recurrent multifocal osteomyelitis pattern.Although it has been clearly stated that vaginal dilation must be considered the first-line treatment for clinical conditions characterized by an absent or hypoplastic vagina, mainly Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a great number of scientific papers on surgical vaginal reconstructions are reported every year. This wide variety of surgical techniques (more than 10) are recognized and performed worldwide, making it difficult to compare results and define an evidence-based approach. Standardized treatment should be considered even more important in the pediatric and adolescent population for the implications offered by the uterus transplantation scenario.
To evaluate the incidence, predictive factors and prognostic value of new-onset persistent left bundle branch block (NOP-LBBB) in patients undergoing sutureless surgical aortic valve replacement (SU-SAVR).
A total of 329 consecutive patients without baseline conduction disturbances or previous permanent pacemaker implantation (PPI) who underwent SU-SAVR with the Perceval valve (LivaNova Group, Saluggia, Italy) in two centres from 2013 to 2019 were included. Patients were on continuous ECG monitoring during hospitalisation and 12-lead ECG was performed after the procedure and at hospital discharge. NOP-LBBB was defined as a new postprocedural LBBB that persisted at hospital discharge. Baseline, procedural and follow-up clinical and echocardiography data were collected in a dedicated database.
New-onset LBBB was observed in 115 (34.9%) patients, and in 76 (23.1%) persisted at hospital discharge. There were no differences in baseline and procedural characteristics between patients with (n=76) and without (n=253) NOP-LBBB. After a median follow-up of 3.3 years (2.3-4.4 years), patients with NOP-LBBB had a higher incidence of PPI (14.5% vs 6.3%, p=0.016), but exhibited similar rates of all-cause mortality (19.4% vs 19.2%, p=0.428), cardiac mortality (8.1% vs 9.4%, p=0.805) and heart failure readmission (21.0% vs 23.2%, p=0.648), compared with the no/transient LBBB group. NOP-LBBB was associated with a decrease in left ventricular ejection fraction (LVEF) at 1-year follow-up (delta -5.7 vs +0.2, p<0.001).
NOP-LBBB occurred in approximately a quarter of patients without prior conduction disturbances who underwent SU-SAVR and was associated with a threefold increased risk of PPI along with a negative impact on LVEF at follow-up.

Splinter haemorrhages are an examination finding that has classically been associated with infective endocarditis (IE), but are not included in current diagnostic algorithms. Splinter haemorrhages have not been evaluated as a diagnostic tool using modern definitions of IE. We determined their sensitivity and specificity in patients with suspected IE and investigated their inclusion in the Duke criteria.
This is a retrospective diagnostic accuracy study using data from 1119 patients with suspected IE referred to the IE service. Patients were categorised according to the Duke criteria, the current diagnostic gold standard, into Duke 'rejected', 'possible' or 'definite' groups. Definite cases (n=451) served as the true positives and rejected cases (n=486) as the true negatives against which splinter haemorrhages were compared. Duke possible cases (n=182) were used the assess the clinical impact of adding splinter haemorrhages to the Duke criteria.
In clinically suspected cases of IE and using the Duke critertainty for some Duke possible cases, while increasing it for a similar proportion of Duke rejected cases.
Recap of atopic eczema (RECAP) is a patient-reported outcome measure assessing eczema control. This instrument has been developed and validated in the UK. There are self-reported and proxy-reported versions in English, Dutch and German. However, it is unclear whether the self-reported version shows adequate content validity when completed by young people (8-16 years) in these languages.
To assess the content validity (comprehensibility, relevance and comprehensiveness) of the English, German and Dutch versions of the self-reported RECAP in young people with atopic eczema and to identify the most appropriate age cutoff for self-completion.
We conducted 23 semistructured cognitive interviews with young people aged 8-16 years, using the 'think-aloud' method. In Germany and the Netherlands, participants were recruited in dermatology clinics and in the UK through social media and existing mailing lists. Interviews were audio recorded, transcribed verbatim and analysed in the three languages, using a problem-topic eczema are formulated. What are the clinical implications of this work? The Dutch, English and German self-completion versions of RECAP are recommended for use in adolescents from the age of 12 years. The proxy version could be used in children younger than 12 years or where children are cognitively or physically incapable of reporting their experience of eczema control. Caregivers should be encouraged to complete RECAP together with their child where possible.
Limited evidence exists on how the presence of multiple conditions affects breast cancer (BC) risk.
We used data from a network hospital-based case-control study conducted in Italy and Switzerland, including 3034 BC cases and 3392 controls. Comorbidity patterns were identified using latent class analysis on a set of specific health conditions/diseases. find more A multiple logistic regression model was used to derive ORs and the corresponding 95% CIs for BC according to the patterns, adjusting for several covariates. A second model was fitted including an additional effect of FH on the comorbidity patterns.
With respect to the 'healthy' pattern, the 'metabolic disorders' one reported an OR of 1.23 (95% CI 1.02 to 1.49) and the 'breast diseases' an OR of 1.86 (95% CI 1.23 to 2.83). The remaining two patterns reported an inverse association with BC, with ORs of 0.77, significant only for the 'hysterectomy, uterine fibroids and bilateral ovariectomy'. In the second model, FH was associated with an increased risk of the 'breast diseases' pattern (OR=4.
