Rationale and Objectives. The aut_horS exaw~ed the prognostic value of magnetic resonance (MR) imaging in stress injuries of bone.Materials and Methods, Clinical follow-up data were collected in 35 patients who underwent MR hnaging because of st~spected stress fractures. MR findings were correlated with total duxation of sYm4~toms; the time to retm'n to sports activity, and findings'at follow-up radiog-• raphy~ :Results. The MR imaging finding of a "fracture" or "fatigue" line or a cortical signal intensity abnormality was predictive of a longer symptomatic period, whereas muscle edema was predictive of a shorter symptomatic w~riod. A published ~-ading system could be used in only 24 patients;, the ]VIR imaging grade of injury did not show correlation with clinical outcome, ' ~-, Conclusion. The MR imaging finding Of either a medullar~ line or a cortical abnormality %~ to indicate a ,more severe stress iiijury of bone: A pre-ciously,put~ , lished MR imaging grading system for stress injuries' of' the tibia was nOVprognostic in this more heterogeneous . patient group.

Background: Tissue advanced glycation end products (AGEs) accumulate in chronic kidney disease (CKD) and are a measure of cumulative metabolic stress. Measurement of tissue AGEs by skin autofluorescence (SAF) correlates well with cardiovascular outcomes in dialysis patients. SAF levels in transplant recipients relative to CKD and dialysis patients have not been previously studied, and the impact of transplantation on SAF levels in dialysis patients is unknown. Methods: SAF was measured using an AGE reader in 66 patients who had received a kidney transplant. Values were compared to those obtained in 1,707 patients with CKD stage 3 and in 115 patients on dialysis. Results: Mean SAF in transplant recipients [2.81 ± 0.64 arbitrary units (AU)] was significantly lower than in patients on haemodialysis (3.73 ± 0.88 AU) and peritoneal dialysis (3.57 ± 0.75 AU; p < 0.001), but was no different from CKD stage 3 (2.79 ± 0.66 AU; p = 0.42). In the transplant group, SAF correlated most strongly with age (r = 0.316). There was no correlation between SAF and estimated glomerular filtration rate or renal replacement therapy vintage. A small cohort of patients with SAF recorded on dialysis and following transplantation showed a drop in SAF over a mean time of 16 months after transplantation. Discussion: Tissue AGE values in kidney transplant recipients are significantly lower than in patients receiving dialysis and similar to those in patients with CKD stage 3. Our data suggest that transplantation may be associated with a reduction in tissue AGEs, and this might be an important component of the observed reduction in cardiovascular risk in transplant recipients compared to patients on dialysis.

Background The Renal Angina Index (RAI) is a validated screening tool used at 12 h of pediatric intensive care unit (PICU) admission to predict severe acute kidney injury (AKI) on day 3 of PICU stay. A measured or height-imputed baseline serum creatinine (SCr) is required for AKI diagnosis and RAI calculation, yet these are often lacking. We assessed an age-based, height-independent baseline SCr calculation and compared the RAI values employing this method to their historical counterpart. Methods An electronic algorithm was implemented to generate RAI score for patients admitted to our PICU. We reviewed 157 consecutive patient records from May 2017, until we cumulated 100 with a valid RAI calculation. We compared RAI scores using the age-based SCr imputation method of Pottel to the historical RAI. Our primary outcome was a difference in the rate of RAI fulfillment (≥8) reclassification between methods. Results Of the first 100 patients, 27 had measured baseline SCr and 73 used height imputation. Only two patients had RAI reclassified with the Pottel method (one in each direction). Being small for age or older were associated with ≥25% overestimation of the baseline SCr in 20 patients with the Pottel method compared with height imputation. 15/157 patients had a falsely positive RAI due to lack of measured baseline SCr and height. Conclusion The age-based method to estimate baseline SCr offers a viable height-independent alternative for RAI calculation. While less precise than a height-based approach, this lack of precision rarely leads to reclassification of patient RAI status.

SUMMARY Background Young people with chronic kidney disease (CKD) have a number of key issues and life changes to manage while also possibly transitioning into adult care. During this time, the nature of their support networks including, social, romantic, family and health care relationships, is changing. Objective To explore these young people's experience and perceptions of their past, current and future relationships and support networks. Design Qualitative study. Participants and Methods Fourteen young adults (8 male, 6 female, aged 18–26 years) with CKD Stages 3–5 participated. Semi‐structured interviews were conducted in order to explore the relationships (friends, family and partners) of young adults with CKD at two UK NHS hospitals. These were transcribed and thematically analysed. Results There were four themes identified. ‘Disclosure—To tell or not to tell?’ identified the challenges young adults face when disclosing their condition to friends and prospective partners. ‘Managing support networks’ showed that participants appreciated support from other young adults with CKD but also desired just ‘being normal’ with their friends. While family support is still significant and much appreciated, some young adults also found it harder to develop their independence. ‘Relationship strains and carer needs’ highlights the impact of CKD on all relationships. Participants were also aware of the needs of their ‘carers’. In ‘Happy ever after?’ young adults expressed concerns about meeting a partner and having children. Conclusions Young adults with CKD need support in helping them manage new and existing relationships, at a time where relationships are taking on different forms and significance. Moreover, support needs for young adults extend beyond the patient, to those who support them; support services need to reflect this.

We present the case of a 32-year-old woman with a previous surgical history of benign mucinous cystadenoma resected in 2012 who underwent magnetic resonance cholangiopancreatography following her second pregnancy in 2020. This demonstrated a large cystic mass in the left subdiaphragmatic space. Histopathology confirmed a well-differentiated primary peritoneal mucinous cystadenocarcinoma displaying cells of a Mullerian origin. We subsequently discuss the aetiology of these conditions separately and explore the possibility of a connection between the two regarding origin or potential malignant transformation that may otherwise have occurred coincidentally in this young patient. We also acknowledge a paucity of evidence regarding subsequent management strategies.

Gastrointestinal stromal tumours (GISTs) are rare - and rectovaginal extragastrointestinal stromal tumours (RV-EGISTs) even rarer. We share a case of RV-EGIST, complemented by high-quality radiological and surgical images. A review of current literature pertaining to RV-EGIST is also included. Our case report highlights the diagnostic challenge presented by extragastrointestinal stromal tumours. Differentiated from overlapping pathologies only by targeted application of immunohistopathology and cytogenetics, the inclusion of RV-EGIST in the differential diagnosis of a rectovaginal tumour is essential to making this correct diagnosis. Primary surgery is the treatment of choice for RV-EGIST if complete cytoreduction can be achieved, combined with adjuvant tyrosine kinase inhibitor (TKI) therapy for those with high-risk features to further reduce rates of future recurrence.
