Acne Scarring Management: Systematic Review and Evaluation of the Evidence

BACKGROUND

Modalities for atrophic acne scarring can be classified depending upon the needs they satisfy; that is, resurfacing, lifting/volumization, tightening, or surgical removal/movement of tissue that is required for correction. A plethora of treatment options have resulted from the need to treat various acne scar types, variability of responses noted in various skin types, and increasing popularity of minimally invasive modalities. Still, there is a lack of consensus guidelines on treatment or combination therapies for various clinical scenarios.

OBJECTIVE

This systematic review includes a critical evaluation of the evidence relevant to these modalities and various multimodality therapies.

METHODS

We performed a systematic literature search in Medline and EMBASE databases for studies on acne scar management. Also, we checked the reference lists of included studies and review articles for further studies. A total of 89 studies were included in our quality of evidence evaluation.

RESULTS

The efficacy of lasers and radiofrequency in atrophic acne scarring is confirmed by many comparative and observational studies. Other modalities can be used as an adjunct, the choice of which depends on the type, severity, and number of atrophic scars. Minimally invasive procedures, such as fractional radiofrequency and needling, provide good outcomes with negligible risks in patients with dark or sensitive skin types.

CONCLUSIONS

There is a lack of high-quality data. Fractional lasers and radiofrequency offer significant improvement in most types of atrophic acne scars with minimal risks and can be combined with all other treatment options. Combination therapies typically provide superior outcomes than solo treatments.

Impact of COVID-19 pandemic on dermatology practices: Results of a web-based, global survey

The spectrum and magnitude of changes in dermatology practice induced by the COVID-19 pandemic have not been adequately studied.

OBJECTIVE

This study aimed to assess the immediate and long-term effects of the pandemic on dermatology practice on a large scale, including the clinical activity of participants, frequency and types of procedures used, and teledermatology (TD) use.

METHODS

This web-based, global survey included 733 dermatologists. The primary outcomes are percentages of respondents providing in-person consultations, hospital service, and TD and performing procedures. Factors in logistic regression models that may influence the odds ratio (OR) for TD use during pandemic and for future use also were analyzed.

RESULTS

The percentages of respondents providing in-person consultations (46.6% vs. 100% before the pandemic) and hospital service (27% vs. 52.8% before the pandemic) as well as performing procedures (25.6% vs. 100% before the pandemic) decreased, whereas practicing TD increased three-fold (75.2% vs. 26.1% before the pandemic) during the pandemic (p < .001 for each). Practice location was associated with TD use during the pandemic and with its expected use in the future (p < .001 for both), with North American respondents indicating the highest use. TD use during the pandemic showed a positive correlation with TD use before the pandemic, performing procedures and, more specifically, with biopsies of suspicious pigmented lesions during the pandemic (p < .001 for each). TD use before the pandemic was the most powerful predictor of TD use during the pandemic (OR: 16.47; 95% confidence interval, 7.12-38.06). More than two third of participants (68.6%) expect to use TD in the future. The factor with the largest increase in OR on the expectation of future TD use was >1000 COVID-19 cases in the country (OR: 3.80; 95% confidence interval, 2.33-6.21).

CONCLUSION

This survey indicates a profound immediate effect of the pandemic on dermatology practice. The pandemic appears to have substantially contributed to an increased use of TD in the long run.

Combination therapy using subcision, needling, and platelet-rich plasma in the management of grade 4 atrophic acne scars: A pilot study

BACKGROUND

Multimodality therapies including minimally invasive modalities are increasingly used in atrophic scarring.

OBJECTIVE

To evaluate the role of platelet-rich plasma (PRP) as adjunctive therapy to a combined subcision and needling treatment in severe (grade 4) atrophic acne scarring.

METHODS

A total of 30 patients with grade 4 acne scars were randomly divided into two groups, 15 patients each: Group A underwent three sequential treatments of subcision and needling while Group B, three sequential treatments of subcision, needling, and topical application of PRP that were performed at 3-week intervals. Scar grading was assessed 3 months following the final session. Participant's assessment of treatment response was registered.

RESULTS

Scar improvement ≥50% was reported significantly more often by Group B than Group A patients (P = 0.025). Regarding physician-based assessment of scar grading post-therapy (number of patients with two grades improvement vs one grade or no improvement), there was a trend toward more improvement in Group B (P = 0.195). Physician's evaluation of acne scar improvement correlated with the patient's assessment of improvement: 60% of Group A and 66.6% of Group B patients appreciated an improvement of 25%-49% and 50%-74%, respectively. Mean duration of postprocedure erythema/edema was shorter among Group B than Group A patients (16.1 vs 32.9 hours, respectively). Overall, substantial improvement was noticed in rolling and boxcar scars with only a mild change in icepick scars.

CONCLUSION

Platelet-rich plasma appears to add to the improvement of grade 4 atrophic acne scars when combined with needling and subcision. These findings require further evaluation by future studies.

Mental distress in dermatologists during COVID-19 pandemic: Assessment and risk factors in a global, cross-sectional study

There is a sparsity of data regarding the mental health status of dermatologists during COVID-19 pandemic. Evaluate the effects of pandemic on mental health of dermatologists on a large scale and identify risk factors for mental distress. 733 dermatologists were included in this cross-sectional, web-based survey. Mental distress was reported by 77.2% of responders. Considerable percentages of participants experienced stress (73.9%), irritation (33.7%), insomnia (30%), or depression (27.6%), and 78.6% were overwhelmed with the amount of pandemic information they were receiving. Mental distress was significantly associated with practice years, volume of patients seen per week before pandemic, personal protective equipment availability at hospital (P = .001 for each), practice location (continent; P < .001), and participant's assessment that the healthcare system was not equipped for the pandemic (P = .003). Stress was associated with hospital service (P = .003), and depression with being overwhelmed with the amount of pandemic information received (P = .004). In a logistic model, teledermatology use was the most powerful predictor of mental distress (OR, 1.57 [95% CI, 1.07-2.32]). Mental distress was common among dermatologists during this pandemic. Teledermatology use was the most powerful predictor of mental distress. Preventative strategies and psychosocial interventions should be implemented.

Global impact on dermatology practice due to the COVID-19 pandemic

This contribution focuses on the effects of coronavirus disease 2019 (COVID-19) on dermatology practice. We discuss the impact on practice volume and procedures and on the considerable increase in teledermatology use. We also describe the important roles that dermatologists have played in enhancing infection prevention and on the frontline. During the crisis, dermatologists have faced the challenge of a shortage of resources, such as personal protective equipment, in the health care system. In addition, they have been involved in managing cutaneous manifestations related to COVID-19 and occupational disease caused by personal protective equipment. Dermatologists have made a diligent effort to identify melanoma and to ensure the treatment of high-risk skin cancers. Safety guidelines have been suggested to minimize the potential risks associated with the systemic use of immunosuppressant agents and immunomodulators in patients with severe inflammatory skin disease during the pandemic. Finally, social distancing necessitated that dermatology conferences take place virtually and teaching via e-learning increased.

Virtual conferences and e-learning in dermatology during COVID-19 pandemic: Results of a web-based, global survey

During the pandemic, virtual conferences became the norm. We conducted a cross-sectional global study to assess dermatologists' responses to virtual conference and e-learning program attendance, as well as to discuss the status of such events during the pandemic. This web-based, global survey included 733 dermatologists. Primary outcomes are percentages of responders answering questions. Assessment of the relationship between two categorical variables was performed with the chi-square test. A substantial percentage of responders were willing to attend a virtual meeting (70.6%) or webinar (80.2%), or to conduct a webinar (47.3%). Among participants who provided resident or fellow training before the pandemic, 38% responded that they did not have any teaching systems in place during the pandemic. Virtual conference attendance was significantly associated with video conference attendance before the pandemic, webinar attendance, teledermatology (TD) use during the pandemic, future TD use, having training systems in place for residents or fellows (P < .001 for each), and North American location of participant (P = .001). Webinar attendance was associated with North American location, conducting webinars (P < .001 for each), and future TD use (P = .024). This pandemic has had a profound effect on dermatology conferences and e-learning programs. Attending video conferences and webinars or other online training was associated with TD use and future use, which indicates that these technologies are all here to stay.

Subcorneal pustular dermatosis: Comprehensive review and report of a case presenting during pregnancy

Subcorneal pustular dermatosis (SPD), also known as Sneddon-Wilkinson disease, is a rare, relapsing, sterile pustular eruption of unknown etiology that develops most commonly in middle-aged or mature women. This article reviews the presentation, associations, and management of the condition and highlights advances in pathophysiology. Onset of SPD during pregnancy has not been reported. Herein, we report a case of SPD that developed during pregnancy. The patient was treated with dapsone without complications for her or the fetus. An association between T helper (Th) 17 and Th2 environments in the development of SPD has been advocated. Pregnancy is characterized by a predominance of Th2 responses and increased interleukin-17 levels and thus may favor the development of the condition.

Impact of COVID-19 Pandemic on Dermatology Practice in India

BACKGROUND

COVID-19 pandemic has disrupted healthcare systems throughout the globe. It has affected dermatology practice to a great extent. Since most of the consultations (except emergencies) in dermatology are deferred as a precautionary measure, dermatologists have taken the route of virtual appointments in order to continue treating patients in the present lockdown state. However, the concept of telemedicine is quite new for doctors as well as for patients in India.

MATERIAL AND METHODS

An online questionnaire was circulated among Indian dermatologists which included participant demographics, changes in their practice and teaching during COVID-19, use of virtual or e-health technologies, and attitudes/opinions on their experiences. We also wanted to understand doctor perspectives on their own roles, wellness, and hospital responses to the pandemic.

RESULTS

A total of 260 responses from qualified dermatologists of different parts of India were received between 1st and 8th April 2020 and were analyzed. Two-thirds of the respondents were within 10 years of starting practice. Virtual consultations have increased by almost three-fold during the pandemic, which is a major change noticed in the practice when we compare before and during the pandemic. Earlier the focus of teledermatology (TD) was mainly for follow-up care (85%), whereas during the pandemic, both new and follow-up patients were provided virtual consultations. The number of patients coming to them for a consultation has drastically reduced. Only 2% of the responders are still performing minor procedures with proper care. Almost two-thirds do not have systems in place to train their residents and fellows due to the disruptions caused by the pandemic. The rest of them have started to take the virtual route of teaching through webinars, virtual rounds, and providing access to online journals to continue their teaching. Only 18.6% of dermatologists at work were provided with personal protective equipment. TD has opened new doors to virtual consultation and it was evident that 54.4% of doctors are willing to continue it in the future even after the pandemic is over.

CONCLUSION

TD platforms hold great promise to improve access to high-quality dermatologic care in the future. Results from this survey of Indian dermatologists suggest that TD is the future of dermatology as it will be accessed by patients in remote areas and it is a cost-effective move for the patients.

Atypical Clinical Presentation of Hidradenitis Suppurativa in a Patient with Severe Mannose-Binding Lectin Deficiency

Mannose-binding lectin (MBL) deficiency is associated with recurrent infections, autoimmune and inflammatory skin disease, and vascular complications. MBL deficiency is not a recognized comorbidity in hidradenitis suppurativa (HS); the latter is associated with the group of autoinflammatory disorders. A 32-year-old woman presented with a history of recurrent painful, deep-seated abscesses and pustular lesions since the age of 13 years. Lesions were noted predominantly in HS distribution, i.e., submammary, inguinal, and perianal areas were affected. However, unusual locations (jawlines, neck) were also affected. The patient fulfilled the clinical criteria for HS but the presentation was atypical because lesions were noted in unusual locations, most lesions were in Hurley stage 1 (sparsity of sinus tracts and scarring), and most cultures from abscesses and pustular lesions were negative. The excruciating pain caused by constantly developing abscesses had a profound impact on the patient's quality of life. Laboratory workup showed an exceptionally low serum MBL level. Treatment was challenging with only a temporary, mild response to oral antibiotic therapy and no response to immunosuppressive and hormonal therapies. This atypical HS presentation may reflect an enhancement of proinflammatory mechanisms. Health care providers should be aware of this clinicopathologic presentation so that the establishment of HS diagnosis is not delayed and the patient receives appropriate counseling.

Evaluating resurfacing modalities in aesthetics

Skin resurfacing for cutaneous rejuvenation has evolved with the development of a plethora of nonsurgical and minimally invasive modalities. We have highlighted the advances in laser therapy, chemical peels, radiofrequency, microneedling, and platelet-rich plasma therapy. We have also included studies providing head-to-head comparisons between procedures and discussed relevant debates in the field. We have examined additionally combination treatments and resurfacing in acne scars, melasma, and skin of color.

Availability of personal protective equipment among dermatologists in the COVID-19 pandemic: Assessment and risk factors in a web-based, global study

BACKGROUND

The availability of personal protective equipment (PPE) among dermatologists during the Coronavirus Disease 2019 (COVID-19) pandemic has not been studied.

METHODS

We have assessed PPE availability among dermatologists and relevant aspects of hospital service by surveying 733 dermatologists.

RESULTS

Considerable percentages of respondents had to purchase their own PPE (40.2%) and were not provided with it at the hospital (37.7%). Only 27% of respondents provided hospital service, and 18.4% were assigned to nondermatologic duty. A substantial percentage (64.4%) indicated the availability of hospital-issued management guidelines (HIMG) for COVID-19 patients. Nearly half of the survey participants (49.1%) responded that the health care system was not equipped for the pandemic. Purchasing one's own PPE was strongly associated with the private practice setting and continent, with the highest rates in Central and South America and in Europe (P < .001). PPE availability at a hospital was associated with 2 continents, with the highest rates in Europe and in North America (P < .001). In logistic regression, the most important factor reducing the odds ratio (OR) for purchasing their own PPE was HIMG for COVID-19 patients (OR, 0.55; 95% confidence interval [CI], 0.32-0.97). Respondents' assessment that the health care system was equipped for COVID-19 was the most powerful increaser of OR for PPE availability (OR, 9.43; 95% CI, 5.37-16.56) followed by >1,000 COVID-19 cases in a participant's country.

CONCLUSIONS

Substantial percentages of respondents had to purchase their own PPE and were not provided with it at the hospital. Strategies to increase PPE availability should be implemented by hospitals, industry, and government authorities.

Two-stage Ear Reconstruction with a Retroauricular Skin Flap after Excision of Trichilemmal Carcinoma

Trichilemmal carcinoma is a rare cutaneous tumor with a frequently good prognosis but without standard criteria for surgical treatment. We aimed to show the results of a two-stage surgical approach that preserves the anatomical features of the ear. We report a case of 82-year-old man with trichilemmal carcinoma of the ear that was treated with a two-stage surgical approach. We observed that 5 months after the surgeries, the ear appeared entirely healed and there were no signs of recurrence; hence, our two-stage surgical approach allowed the anatomy of the ear to be preserved after the complete excision of the tumor.

Evolving eponymous signs in diagnostic dermoscopy

Dermoscopy is a very useful technique devised for an earlier diagnosis of skin melanoma with a clinic-pathological correlation. Later it was found to be beneficial for the diagnosis of many other pigmented skin lesions, such as seborrheic keratosis, pigmented basal cell carcinoma, hemangioma, blue nevus, atypical nevus, and mole, which can often clinically simulate melanoma. Of late, its use in general clinical dermatology is growing with the recognition of new and specific patterns in conditions such as hair disorders, inflammatory disorders, and infections/infestation. It is still in the evolving phase and many new signs are described presently. Eponyms are used almost daily in dermatology practice. The eponyms in dermoscopy, trichoscopy, and onychoscopy are based on the imaginative capability of the authors and they have been very much successful in describing them. It becomes easier to memorize and identify the various appearances for early diagnosis and management. In this article we attempt to highlight the various dermoscopic signs described in dermatology.

Erosive Pustular Dermatosis: Delving into Etiopathogenesis and Management

Erosive pustular dermatosis (EPD) is a chronic inflammatory skin disorder that usually affects mature individuals. It predominantly affects the scalp and can lead to scarring alopecia. Risk factors include actinic damage and androgenetic alopecia. A traumatic insult to the skin is considered a vital trigger of the condition. EPD is a diagnosis of exclusion; thus, several neoplastic, infectious, vesiculobullous, and inflammatory conditions should be ruled out. Biopsy and clinicopathologic correlation are required to differentiate between EPD and these entities. A dysregulated, chronic immune response is considered central to the etiopathogenesis of EPD. We performed an evidence-based systematic review of the management options. There were predominantly studies with level IV and V evidence and only two with level III. Despite the responsiveness of EPD to potent topical steroids, such as clobetasol propionate, recurrence occurs after treatment withdrawal. With the available data, tacrolimus 0.1%, curettage-assisted aminolevulinic acid-photodynamic therapy, and systemic retinoids can be considered second-line options for EPD with a role in maintenance regimens. However, controlled data and more powerful studies are needed to make solid recommendations.
