Background: Dermoscopy is known to increase the diagnostic accuracy of pigmented skin lesions (PSLs) when used by trained professionals. The effect of dermoscopy training on the diagnostic ability of dermal therapists (DTs) has not been studied so far. Objectives: This study aimed to investigate whether DTs, in comparison with general practitioners (GPs), benefited from a training programme including dermoscopy, in both their ability to differentiate between different forms of PSL and to assign the correct therapeutic strategy. Methods: In total, 24 DTs and 96 GPs attended a training programme on PSLs. Diagnostic skills as well as therapeutic strategy were assessed, prior to the training (pretest) and after the training (post-test) using clinical images alone, as well as after the addition of dermatoscopic images (integrated post-test). Bayesian hypothesis testing was used to determine statistical significance of differences between pretest, post-test and integrated post-test scores. Results: Both the DTs and the GPs demonstrated benefit from the training: at the integrated post-test, the median proportion of correctly diagnosed PSLs was 73% (range 30–90) for GPs and 63% (range 27–80) for DTs. A statistically significant difference between pretest results and integrated test results was seen, with a Bayes factor>100. At 12 percentage points higher, the GPs outperformed DTs in the accuracy of detecting PSLs. Conclusions: The study shows that a training programme focusing on PSLs while including dermoscopy positively impacts detection of PSLs by DTs and GPs. This training programme could form an integral part of the training of DTs in screening procedures, although additional research is needed.

BACKGROUND: Burn survivors are frequently faced with disfiguring scars. Various techniques exist to improve scar appearance, such as laser treatment and dermabrasion. Next to that, surgical reconstruction, such as scar excision is an option. This randomized controlled trial investigates whether a larger burn scar can be excised using a skin-stretching device for wound closure, thereby optimizing use of adjacent healthy skin. This technique may allow scar excision in a one-step procedure instead of two or more steps, which is necessary for serial excision and tissue expansion.METHODS: Two arms were compared: scar excision and closure by skin stretch and scar excision without additional techniques. The primary outcome measure was scar surface area reduction. In addition, complications were registered.RESULTS: Fifteen patients were randomized for skin stretch and 15 patients were randomized for scar excision only. In the skin stretch group, 10 of 15 scars were completely excised compared with three of 15 in the scar excision-only group (p = 0.025). In the skin stretch group, a significantly larger reduction in scar area was achieved: 95 ± 11 percent of the scar was excised versus 78 ± 17 percent in the scar excision-only group (p = 0.003). One patient in the skin stretch group and three patients in the scar excision-only group experienced partial wound dehiscence (p = 0.598).CONCLUSIONS: In burn scar reconstructions, a significantly larger reduction in scar area can be achieved using a skin-stretching device compared with scar excision with no additional techniques, without an increased risk of complications. It was shown that skin stretching is of added value for scars that cannot be excised in a one-step procedure.

Structured experience (SE) providers continuously evaluate and improve their experiential offerings to make them more memorable. Arguably, the temporal dynamics of the emotions in an experience have a crucial influence on its memorability. Traditional post-experience evaluation procedures tend to ignore these temporal dynamics, thus offering imprecise feedback for providers on exactly when and where to optimize their experiential offerings. In this paper, we use two methods as a tool for evaluating how closely the lived experience of a SE follows the experience as intended by the provider: real-time skin conductance (SC) and experience reconstruction measures (ERMs). We demonstrate that both SC and ERMs are significantly related to intended experience. This link was found to be stronger for later sections of the experience than for earlier sections. In addition, SC and ERMs appear to be useful tools to assess the effectiveness of design interventions, thus providing valuable feedback for SE providers.

Google wants to “help computers ‘see’ our world”, and one of their ways of battling how current AI and machine learning systems perpetuate biases is to introduce a more inclusive scale of skin tone, the ‘Monk Skin Tone Scale’.

The worldwide rise of skin cancer incidence rates increases the need to investigate ultraviolet radiation (UVR), as it is one of the main causes of skin cancer. 1 A ’ u to UVR varies depending on different factors such as the location of the individual and shielding effects. In this analysis, we evaluated wearables at different body positions measuring ultraviolet radiation when worn during daily activities at different locations. First, we analyzed which of the body positions provide the most robust measurements. We then devised a new measure, the horizon shielding factor, to evaluate the effect of horizon shielding and explored if high/low horizon shielding factor values coincide with particular geospatial attributes.

Acne vulgaris is considered one of the most common medical skin conditions globally, affecting approximately 85% of individuals worldwide. While acne is most prevalent among adolescents between 15 to 24 years old, it is not uncommon in adults either. Acne addresses a number of different challenges, causing a multidimensional disease burden. These challenges include clinical sequelae, such as post inflammatory hyperpigmentation (PIH) and the chance of developing lifelong disfiguring scars, psychological aspects such as deficits in health related quality of life, chronicity of acne, economic factors, and treatment-related issues, such as antimicrobial resistance. The multidimensionality of the disease burden stipulates the importance of an effective and timely treatment in a well organised care system. Within the Netherlands, acne care provision is managed by several types of professional care givers, each approaching acne care from different angles: (I) general practitioners (GPs) who serve as ‘gatekeepers’ of healthcare within primary care; (II) dermatologists providing specialist medical care within secondary care; (III) dermal therapists, a non-physician medical professional with a bachelor’s degree, exclusively operating within the Australian and Dutch primary and secondary health care; and (IV) beauticians, mainly working within the cosmetology or wellness domain. However, despite the large variety in acne care services, many patients experience a delay between the onset of acne and receiving an effective treatment, or a prolonged use of care, which raises the question whether acne related care resources are being used in the most effective and (cost)efficient way. It is therefore necessary to gain insights into the organization and quality of Dutch acne health care beyond conventional guidelines and protocols. Exploring areas of care that may need improvement allow Dutch acne healthcare services to develop and improve the quality of acne care services in harmony with patient needs.
