Consensus reclassification of inherited epidermolysis bullosa and other disorders with skin fragility

Abstract: Background: Several new genes and clinical subtypes have been identified since the publication in 2014 of the report of the last International Consensus Meeting on Epidermolysis Bullosa (EB). Objectives: We sought to reclassify disorders with skin fragility, with a focus on EB, based on new clinical and molecular data. Methods: This was a consensus expert review. Results: In this latest consensus report, we introduce the concept of genetic disorders with skin fragility, of which classical EB represents the prototype. Other disorders with skin fragility, where blisters are a minor part of the clinical picture or are not seen because skin cleavage is very superficial, are classified as separate categories. These include peeling skin disorders, erosive disorders, hyperkeratotic disorders, and connective tissue disorders with skin fragility. Because of the common manifestation of skin fragility, these ‘EB-related’ disorders should be considered under the EB umbrella in terms of medical and socioeconomic provision of care. Conclusions: The proposed classification scheme should be of value both to clinicians and researchers, emphasizing both clinical and genetic features of EB. What is already known about this topic?. Epidermolysis bullosa (EB) is a group of genetic disorders with skin blistering. The last updated recommendations on diagnosis and classification were published in 2014. What does this study add?. We introduce the concept of genetic disorders with skin fragility, of which classical EB represents the prototype. Clinical and genetic aspects, genotype–phenotype correlations, disease-modifying factors and natural history of EB are reviewed. Other disorders with skin fragility, e.g. peeling skin disorders, erosive disorders, hyperkeratotic disorders, and connective tissue disorders with skin fragility are classified as separate categories; these ‘EB-related’ disorders should be considered under the EB umbrella in terms of medical and socioeconomic provision of care.

Longitudinal evaluation and decline of antibody responses in SARS-CoV-2 infection

Abstract: Antibody (Ab) responses to SARS-CoV-2 can be detected in most infected individuals 10-15 days following the onset of COVID-19 symptoms. However, due to the recent emergence of this virus in the human population it is not yet known how long these Ab responses will be maintained or whether they will provide protection from re-infection. Using sequential serum samples collected up to 94 days post onset of symptoms (POS) from 65 RT-qPCR confirmed SARS-CoV-2-infected individuals, we show seroconversion in >95% of cases and neutralizing antibody (nAb) responses when sampled beyond 8 days POS. We demonstrate that the magnitude of the nAb response is dependent upon the disease severity, but this does not affect the kinetics of the nAb response. Declining nAb titres were observed during the follow up period. Whilst some individuals with high peak ID50 (>10,000) maintained titres >1,000 at >60 days POS, some with lower peak ID50 had titres approaching baseline within the follow up period. A similar decline in nAb titres was also observed in a cohort of seropositive healthcare workers from Guy′s and St Thomas′ Hospitals. We suggest that this transient nAb response is a feature shared by both a SARS-CoV-2 infection that causes low disease severity and the circulating seasonal coronaviruses that are associated with common colds. This study has important implications when considering widespread serological testing, Ab protection against re-infection with SARS-CoV-2 and the durability of vaccine protection.

Management of sexual dysfunction in patients with cardiovascular disease: recommendations of the Princeton Consensus Panel.

Abstract: Sexual dysfunction is highly prevalent in both sexes and adversely affects patients' quality of life and well being. Given the frequent association between sexual dysfunction and cardiovascular disease, in addition to the potential cardiac risk of sexual activity itself, a consensus panel was convened to develop recommendations for clinical management of sexual dysfunction in patients with cardiovascular disease. Based upon a review of the research and presentations by invited experts, a classification system was developed for stratification of patients into high, low, and intermediate categories of cardiac risk. The large majority of patients are in the low-risk category, which includes patients with (1) controlled hypertension; (2) mild, stable angina; (3) successful coronary revascularization; (4) a history of uncomplicated myocardial infarction (MI); (5) mild valvular disease; and (6) no symptoms and /=3 risk factors for coronary artery disease. These patients should receive further cardiologic evaluation before restratification into the low- or high-risk category. Finally, patients in the high-risk category include those with (1) unstable or refractory angina; (2) uncontrolled hypertension; (3) congestive heart failure (class III or IV); (4) very recent MI (<2 weeks); (5) high-risk arrhythmias; (6) obstructive cardiomyopathies; and (7) moderate-to-severe valvular disease. These patients should be stabilized by specific treatment for their cardiac condition before resuming sexual activity or being treated for sexual dysfunction. A simple algorithm is provided for guiding physicians in the management of sexual dysfunction in patients with varying degrees of cardiac risk.

Development of medical checklists for improved quality of patient care

Abstract: Background. Checklists are used in both medical and non-medical industries as cognitive aids to guide users through accurate task completion. Their development requires a systematic and comprehensive approach, particularly when implemented in high intensity fields such as medicine. Objective. A narrative review of the literature was conducted to outline the methodology to designing and implementing clear and effective medical checklists. Methods. We systematically searched for relevant English-language medical and non-medical literature both to describe where checklists have been demonstrated to improve delivery of care and also, how to develop valid checklists. Results. The MEDLINE search yielded 8303 citations of which 1042 abstracts were reviewed. On the basis of criteria for inclusion and subsequent full-manuscript review, 178 sources, including 17 non-medical publications, were included in the narrative review. This information was further supplemented by expert opinion in the area of checklist development and implementation. A small number of strategies for designing effective checklists were referenced in the literature, including utilization of pre-published guidelines, formation of expert panels and repeat pilot-testing of preliminary checklists. Conclusion. Despite currently available evidence, a highly effective, standardized methodology for the development and design of medical-specific checklists has not previously been developed and validated, which has likely contributed to their inconsistent use in several key fields of medicine, despite evidence of their fundamental role in error management.
