Recognition and management of congenital ichthyosis in a low-income setting

We report the case of a 3-week old girl in The Gambia who presented to hospital with an undiagnosed skin disorder evolving since birth. Using telemedicine to seek specialist dermatology advice abroad, she was diagnosed with and managed for suspected congenital lamellar ichthyosis. Poor early recognition and limited resources, for both acute and chronic care, created significant challenges to optimal management; these were overcome, in part, by adopting a common sense, back-to-basics approach to treatment and by empowering the parents to take ownership of their infant’s daily skin and eye care. This case highlights key global health issues associated with managing chronic, often debilitating, paediatric dermatological conditions in a low-income setting; namely, poor access to important diagnostic tools and medications, lack of experience and expertise in the management of severe skin disease and its associated complications, absence of long-term community support, alternative health beliefs and risk of sociocultural stigma.</jats:p

Non-invasive Ischaemia Testing in Patients With Prior Coronary Artery Bypass Graft Surgery: Technical Challenges, Limitations, and Future Directions

Coronary artery bypass graft (CABG) surgery effectively relieves symptoms and improves outcomes. However, patients undergoing CABG surgery typically have advanced coronary atherosclerotic disease and remain at high risk for symptom recurrence and adverse events. Functional non-invasive testing for ischaemia is commonly used as a gatekeeper for invasive coronary and graft angiography, and for guiding subsequent revascularisation decisions. However, performing and interpreting non-invasive ischaemia testing in patients post CABG is challenging, irrespective of the imaging modality used. Multiple factors including advanced multi-vessel native vessel disease, variability in coronary hemodynamics post-surgery, differences in graft lengths and vasomotor properties, and complex myocardial scar morphology are only some of the pathophysiological mechanisms that complicate ischaemia evaluation in this patient population. Systematic assessment of the impact of these challenges in relation to each imaging modality may help optimize diagnostic test selection by incorporating clinical information and individual patient characteristics. At the same time, recent technological advances in cardiac imaging including improvements in image quality, wider availability of quantitative techniques for measuring myocardial blood flow and the introduction of artificial intelligence-based approaches for image analysis offer the opportunity to re-evaluate the value of ischaemia testing, providing new insights into the pathophysiological processes that determine outcomes in this patient population.</jats:p

HER-SAFE study design: an open-label, randomised controlled trial to investigate the safety of withdrawal of pharmacological treatment for recovered HER2-targeted therapy-related cardiac dysfunction

Introduction A quarter of breast cancers show human epidermal growth factor-2 (HER2) overexpression, where targeted therapy dramatically improves survival. However, cancer therapy-related cardiac dysfunction (CTRCD) occurs in up to 15% of patients. With the interruption of HER2 therapy, if necessary, and the initiation of heart failure therapy (HFT), HER2 CTRCD recovers in over 80% of cases. The need to continue HFT in ‘recovered’ HER2 CTRCD following completion of HER2 therapy is unclear and there are potential significant impacts on patient’s quality of life (QoL). The Randomised Controlled Trial for the Safety of Withdrawal of Pharmacological Treatment for Recovered HER2 Targeted Therapy Related Cardiac Dysfunction (HER-SAFE) aims to evaluate whether HFT can be safely withdrawn in non-high cardiovascular (CV) risk patients with ‘recovered’ HER2 CTRCD.Methods and analysis This is a multicentre, open-label randomised controlled trial investigating whether withdrawal of HFT is non-inferior to continuation in non-high CV risk, breast cancer survivors with recovered HER2 CTRCD after cancer treatment completion. The primary endpoint is the incidence of guideline-defined cardiac dysfunction or clinical heart failure. Secondary endpoints include changes in cardiac blood biomarkers, cardiovascular magnetic resonance (CMR)-derived strain and tissue mapping and heart failure symptom questionnaires. The study will recruit 90 participants who will undergo serial clinical assessment over 12 months with advanced cardiovascular imaging (CMR scans with automated analysis at baseline, 6 and 12 months), cardiac biomarker measurement (six time points over 12 months), plus complete heart failure QoL and medication disutility questionnaires. This is the first multicentre study to address this significant clinical issue.Ethics and dissemination This study was approved by the research ethics committee (London—London Bridge, 23/LO/0152). The results will be disseminated in peer-reviewed scientific journals.Trial registration number NCT05880160
