One study showed that the differences between the skin microbiota in acne and rosacea can provide an understanding of disease progression
Laser treatment in hirsutism: an update
In aesthetic clinics, one of the most common problems seen is unwanted hair. Usually, this is treated by using methods such as shaving, waxing and epilation. While these methods are effective, they are only a temporary solution.
In the last 10 years or so, the use of lasers and light-based technologies for unwanted hair has become one of the fastest growing treatments and methods in aesthetic clinics. Results have shown that laser treatments have excellent results for treating unwanted hair.
The aim of this article is to review the numerous laser and light-based medical devices used for removing hair, as well as looking at the different laser and patient factors that could potentially affect the overall outcome of laser treatment for hair removal.
Comparison of the skin microbiota in acne and rosacea
While there are similar clinical presentations in patients presenting with acne and rosacea, it is considered that there are fundamental clinical differences in their pathophysiology.
The authors of this article looked at a case-control study that profiled the microbiota in rosacea and acne patients skin, and then compared the results to the control group used.
To carry out this study, the authors looked at 19 rosacea and eight acne patients. These patients were matched to the control group.
The results showed that the mean relative abundance of cutibacterium acnes in rosacea with inflammatory papules and pustules was more similar to that of acne than that of rosacea without inflammatory papules and pustules.
In conclusion to this study, the authors state that this has shown that the differences between the skin microbiota in acne and rosacea can provide an understanding of the disease progression in both acne and rosacea.
Teledermatology—its place in modern skin healthcare worldwide
Virtual consultations for patients is not a new concept in aesthetic medicine or dermatology.
‘Telemedicine’ spans back to the 1960s, when the two-way television was used in psychiatry and for military personnel abroad. However, since the 1980s, telemedicine has provided the basis for the ehealth. Dermatology, as well as other medical specialities, are suitable for telecommunication in practice. As with all developments in medicine, the purpose is to improve healthcare.
To analyse and evaluate the impact of teledermatology, the authors focused on reviewing 830 papers.
It was found that 23 of these papers could be evaluated for four outcome measures: time effectiveness, costs, accuracy and feasibility.
This study reports that the standards of care are comparable with regard to feasibility and accuracy. A long-term comparison of the different factors in relation to the effectiveness, costs, accuracy and feasibility with face-to-face consultation is needed.
In conclusion, telemedicine is an excellent tool for the improvement of healthcare worldwide, especially during the COVID-19 global pandemic.
The majority of filler-related blindness cases occurred from injecting hyaluronic acid fillers
Effects of skin care habits on the development of rosacea: a multi-center retrospective case-control survey in Chinese population
Currently, there is little or no published epidemiologic evidence to prove that certain cosmetics could trigger or aggravate rosacea.
The aim of this study was to observe whether daily skin care routines could have an effect on the development of rosacea in Chinese population.
To conduct this study, a multi-centre retrospective case-control survey of 1245 rosacea cases and 1538 skin-healthy controls was carried out in China.
The participants in the trial were asked to complete a questionnaire regarding their daily skin care routine and the products that they use. The data was collected and analysed using the chi-square test and T-test.
The results of this study showed that the use of moisturisers and sun cream presented significantly negative correlations with rosacea.
The frequency of cleansing the skin showed a nonlinear association with rosacea: using facial cleansers 1–3 times per week showed beneficial effects while using facial cleanser excessively positively correlated to rosacea strongly.
In conclusion to this study, it was found that excessive use of facial cleanser, using facial masks, wearing makeup frequently and having regular treatments and using products from a beauty salon were closely correlated with rosacea development in the Chinese population.
Global reporting of cases of COVID-19 in psoriasis and atopic dermatitis: an opportunity to inform care during a pandemic
The authors of this article wanted to bring medical professionals' attention to the PsoPROTECT (Psoriasis Patient Registry for Outcomes, Therapy and Epidemiology of Covid-19 infecTion) and SECURE-AD (Surveillance Epidemiology of Coronavirus Under Research Exclusion-Atopic Dermatitis) registries. These two initiatives have been set up globally for practitioners to gain a better understanding of COVID-19 outcomes in the common cutaneous immunemediated inflammatory diseases (IMIDs) psoriasis and atopic dermatitis.
Update in soft-tissue filler-associated blindness
The use of injecting soft dermal filler is an increasingly popular non-surgical aesthetic procedure. Furthermore, there has been an increasing number of adverse effects reported from the use of soft dermal filler injections, including blindness.
The aim of this study was to look at the reported cases of filler-related blindness in research and published articles from 2015 onwards.
The papers used in this study were found on the MEDLINE database. The articles used were from 1 January 2015 to 1 August 2018.
The results of this study found 60 new cases of filler blindness. The most common type of filler reported was hyaluronic acid (HA), followed by autologous fat and calcium hydroxyapatite.
The nose, glabella and forehead were the most common injection sites noted. There were 10 cases that reported vision restoration. Four of these cases were successfully treated by injecting hyaluronidase, which included retrobulbar hyaluronidase injection.
In conclusion, there have been 60 reported cases of soft-tissue filler blindness since 2015. The majority of these cases occurred from injecting hyaluronic acid fillers, which the authors state is a change from previous reports. In HA cases, hyaluronidase injection may be successful in restoring vision if promptly administered. It is imperative that aesthetic practitioners and injectors are familiar with strategies for managing soft-tissue filler blindness.
