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.

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.

Efficacy of 595- and 1319-nm pulsed dye laser in the treatment of acne vulgaris: a narrative review

Acne is one of the commonest problems of adolescence with almost half of the patients experiencing persistence into adulthood. Pulsed dye lasers (PDL) with wavelengths of 585 and 595 nm targeting hemoglobin have been used for the treatment of this condition and its sequelae. Recent introduction of PDL with a higher wavelength of 1319 nm has been reported to offer some benefit to acne patients. We reviewed the literature on the use of 595-nm and 1319-nm PDL in the management of acne. A PubMed literature search for search terms "pulsed dye laser," "acne laser therapy," "light therapy for acne," "595 nm and acne," "1319 nm and acne" was done. Studies, series and case reports were included. These lasers were compared to other lasers and light sources such as 532-nm Potassium Titanyl Phosphate laser, 585-nm PDLs, 1450-nm diode laser, 1540-nm erbium glass laser, intense-pulsed light (IPL), photodynamic therapy, red and blue light and short-pulsed 1064 nm laser utilized in acne management regarding their efficacy. Improvement in acne grading, scale severity or reduction in lesion count indicated substantial efficacy of the laser system utilized.

Update in minimally invasive periorbital rejuvenation with a focus on platelet-rich plasma: A narrative review

BACKGROUND

The periorbital region is among the first areas to be affected by the process of aging, which is influenced by genetic and constitutional factors. As the region plays an important role in overall facial appearance, rejuvenation of the area has immense cosmetic benefit and various treatment modalities have been used to achieve the same.

AIMS

This article reviews commonly used non-surgical and minimally invasive modalities for periorbital rejuvenation.

METHODS

The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles. Only articles available in English were considered for this review.

RESULTS

Autologous platelet rich plasma (PRP) is increasingly used in dermatology for skin and hair conditions. The use of PRP is rapidly growing in popularity as a modality to achieve skin rejuvenation. The mechanism by which PRP leads to skin rejuvenation is by increasing the dermal fibroblast proliferation, expression of matrix metalloproteinase and collagen synthesis.

CONCLUSION

The evidence discussed in this article indicates the increasing importance of minimally invasive modalities in periorbital rejuvenation and a promising role for PRP as solo therapy or in multimodality regimens.

Complications of botulinum toxin and fillers: A narrative review

BACKGROUND

Cosmetic surgery and esthetic procedures have become a billion dollar industry owing to the ever-growing demand of the population to stay young. The injectable treatments including fillers and botulinum toxin have become highly popular because of their quick, predictable and lasting results in the management of facial wrinkles and rejuvenation. Although these treatment modalities are relatively safe, they are associated with certain side effects.

AIMS

In this review, we will focus on the complications of fillers and botulinum toxin.

PATIENTS/METHODS

The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles. Only articles available in English were considered for this review.

RESULTS

Brow ptosis and asymmetry are common adverse effects of botulinum toxin while the most common adverse effects associated with fillers are the local injection related effects manifesting as erythema, edema, pain, and ecchymosis.

CONCLUSION

It is important that the treating physician is well verse with the various fillers and botulinum toxin complications and their management as some of the complications can be severely debilitating.

Skin disease related to metabolic syndrome in women

Sex hormones are involved in pathways of metabolic syndrome (MetS), an observation supported by animal studies. The relationships of sex hormones with components of MetS, such as insulin resistance and dyslipidemia, have been studied in pre- and postmenopausal women. High testosterone, low sex hormone-binding globulin, and low estrogen levels increase the risks of MetS and type 2 diabetes in women. Cutaneous diseases that are sex hormone mediated, such as polycystic ovary syndrome, acanthosis nigricans, acne vulgaris, and pattern alopecia, have been associated with insulin resistance and increased risk for MetS. Furthermore, inflammatory skin conditions, such as hidradenitis suppurativa and psoriasis, increase the risk for MetS. Patients with such skin conditions should be followed for metabolic complications, and early lifestyle interventions toward these populations may be warranted.

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.

Vaginal rejuvenation: From scalpel to wands

Vaginal rejuvenation procedures are increasing in popularity in terms of types of treatment offered, number of patients undergoing them, clinical studies, and in the controversy surrounding them. Both non-invasive and invasive solutions are being developed by pharmaceutical and technological companies. Radiofrequency devices and lasers are spearheading the energy-based device space, and fillers and platelet-rich plasma are used to address several concerns surrounding vaginal health. In this review, an overview of the growing field of vaginal rejuvenation is presented, as well as the authors’ personal view and analysis of this clinical space.

Travelers' tropical skin diseases: Challenges and interventions

Tropical regions receive a significant part of the traveling population. It is very important that health professionals are familiar with the main tropical skin diseases and able to advice patients appropriately. This article reviews the main tropical diseases of travelers, with an emphasis on diagnosis, management, and prevention. Among others, cutaneous larva migrans, myiasis, tungiasis, Chagas disease, Dengue fever, African trypanosomiasis, filariasis, and leishmaniasis are discussed. Increasing awareness among travelers and health care professionals can help reduce morbidity and mortality. Continued research on new drugs and vaccines is needed to reduce the risks of tropical diseases.

Skin excoriations: picking apart the picker

Management of patients who pick at their skin can be challenging. Etiologies and maintaining factors of skin picking are often unclear. Significant psychiatric overlay is often present, and the clinician is left with an overwhelming differential diagnosis and poorly focused management plans which can result in suboptimal clinical outcomes. The purpose of this article is to provide a conceptual framework for the evaluation and treatment of a patient presenting with excoriations. Ten diagnostic categories of pickers are described, and specific suggestions for treatment are offered.

Body dysmorphic disorder in the cosmetic practice

Body dysmorphic disorder (BDD) is a preoccupation with a slight or imagined flaw in appearance that causes significant distress and impairment in daily functioning. The disease is more prevalent among patients who seek aesthetic procedures as compared with population standards or individuals that are not interested in aesthetic surgery. Several studies have indicated that BDD symptoms typically worsen after an aesthetic procedure because the preoccupation shifts to a different body area. This review discusses the demographic and clinical features, psychiatric comorbidity, assessment, differential diagnosis, and management of BDD. Components of the assessment include the interview, patient observation in the office, and questionnaires. The article includes a detailed discussion on questionnaires, especially those that are most useful in the dermatology or cosmetic practice. Ethical considerations in the management of BDD are discussed. BDD should not be missed by health providers because of the associated high morbidity that includes an increased suicidality. The cosmetic provider's approach should motivate BDD patients to participate in treatment, a combination of psychotherapy and pharmacotherapy.

Genital diseases in the mature woman

Vulvovaginal conditions are common in mature women. This reflects age-related changes in immunity and skin barrier function of vulvovaginal tissues. Vaginal atrophy is commonly complicated by dryness and inflammation, which makes postmenopausal atrophic vaginitis a virtually ubiquitous condition. The differential of vaginitis includes inflammatory, infectious, and malignant diseases, plus drug hypersensitivity. Atrophic vaginitis is treated with estrogen replacement therapy. Vulvovaginal malignant melanoma occurs predominantly in postmenopausal women and carries a poor prognosis. Similarly, the incidence of vulvovaginal malignancies, such as squamous cell carcinoma and extramammary Paget disease, rises exponentially after 65 years of age. Early diagnosis of these malignancies is of utmost importance. Lichen sclerosus et atrophicus and vulvovaginal candidosis are among the most common postmenopausal vulvovaginal conditions. Lichen sclerosus et atrophicus is associated with significant morbidity, and its management can be challenging. The incidence of vulvovaginal candidosis increases in patients on estrogen replacement therapy.
