Melasma is an acquired disorder of hyperpigmentation affecting millions of individuals worldwide. It is mostly observed in the facial area of darker-complexioned individuals (skin types IV-VI) exposed to intense ultraviolet (UV) radiation 1 and shorter wavelengths of visible light (VL). 2 At least 90% of those affected are women. 1 Melasma is characterized by symmetrically oriented hyperpigmented macules and patches, with varying presentations including blotchy, irregular, arcuate, and polycyclic. 3 One way of dividing the disorder into different subtypes is based on the distribution pattern: centrofacial (the most common), malar, and mandibular. Another division is

In this case series, vitiligo patients had a higher rate of choroidal nevi than previously reported. The hypopigmentary vitiliginous fundus lesions were depicted on OCT as photoreceptor and RPE atrophy. These findings may suggest the advisability of regular ocular monitoring for vitiligo patients.

Pityriasis rubra pilaris (PRP; MIM 173200) is an uncommon papulosquamous inflammatory dermatosis. Only a few cases of PRP associated with an underlying malignancy have been documented. We investigated a 59-year-old patient presenting with a fulminant form of PRP recalcitrant to systemic retinoid therapy, in whom the skin disease heralded a diagnosis of cholangiocarcinoma. We searched the MEDLINE database to find articles reporting on similar associations of PRP with malignancies. We identified 10 studies linking PRP and malignancies, but an association between PRP and cholangiocarcinoma has not yet been reported.

Successful treatment of Hailey-Hailey disease with intradermal botulinum toxininjections has been previously reported. The main disadvantages of this treatment are the excruciating pain and the risk of infections due to the numerous injections.We sought to evaluate the clinical effectiveness and safety profile of a novel approach using an energy-based device (Tixel, Novoxel, and Israel), followed by the topical application of botulinum toxin Type A for the treatment of Hailey-Hailey disease. A retrospective study of all cases of histologically diagnosed cases of Hailey-Hailey disease treated with Tixel device followed by topical application of botulinum toxin between 2018 and 2019 was performed. Epidemiologic, clinical, and treatment data, including effectiveness score and safety, were reviewed. The study included eight patients, of whom seven patients (87.5%) showed good or partial response. No systemic or local adverse effects were reported. There was no difference in effectivity between different body areas. Response to treatment ranged between patients with an average duration of 7.125 months after the second treatment. Tixel treatment followed by topical application of botulinum toxin can be considered in the treatment of Hailey-Hailey disease. This approach is less invasive, less painful, and yet effective as well as safe.

Background: Melasma is an acquired disorder of hyperpigmentation, affecting a million individuals worldwide. Energy-based devices (EBDs) employed to treat melasma include various types of lasers, intense pulsed light (IPL), and radiofrequency (RF).Recent studies have attempted to address recalcitrant and recurring melasma by combining energy-based devices with topical or oral medications.Objective: This article reviews EBDs-based augmented treatment for melasma and suggests practical pathogenesis-oriented treatment regimens. Treatment algorithms are proposed to address various components of melasma.Methods: A systematic PubMed search was conducted acquiring information from various studies on combination treatments of melasma involving EBDs. Results:The 286 retrieved articles were filtered by title to contain at least one type of energy-based modality such as laser, IPL, or RF along with at least one other treatment method. Based on their subject matter, combinations were further categorized into the subheadings: laser plus medication, laser plus laser, and IPL-and RF-containing treatment methods. Conclusion:There are many energy-based combination treatments that have been explored for mitigation of melasma including laser therapy with medication, multilaser therapies, IPL, RF, and microneedling devices. Melasma is an exceedingly difficult condition to treat, however, choosing the appropriate tailor-made treatment combination can improve the final outcome.

Griseofulvin and terbinafine are considered effective first‐line therapies for tinea capitis (TC). Haematological dyscrasias and hepatic injury are possible adverse effects with both drugs. There is a debate in the literature regarding the necessity of laboratory monitoring during griseofulvin and terbinafine treatment. We aimed at assessing the prevalence and severity of haematological and hepatic laboratory test abnormalities in a paediatric cohort of African immigrants in Tel‐Aviv with TC who were treated with Terbinafine or Griseofulvin. We conducted a retrospective study of all TC cases diagnosed and treated at the paediatric dermatology clinic, Tel‐Aviv Medical centre, between June 2013 and March 2019. Epidemiologic, clinical and laboratory data were collected. Our cohort included 321 patients of whom 225 (70%) were treated with Griseofulvin and 96 (30%) with Terbinafine. We identified a total of 64 (20%) patients with haematological or hepatic laboratory test abnormalities that in most cases (96.3%) were considered as mild. No difference in laboratory abnormalities prevalence was identified between the griseofulvin and terbinafine groups (21.3% and 16.6%, respectively). Only one patient treated with Griseofulvin revealed significantly increased levels of hepatic aminotransferases that required discontinuation of treatment. Mild elevation in hepatic transaminases is relatively common among paediatric patients treated with systemic antifungal treatment for TC. However, significant laboratory abnormalities are extremely rare and may be diagnosed and addressed early through periodic laboratory tests monitoring.

We present a rare co-occurrence of anterior scleritis developing in a patient with recalcitrant pemphigus vulgaris. We discuss the clinical and therapeutic implications of these two conditions and offer concise recommendations.

Background: Infantile hemangiomas (IHs) are the most common vascular tumors in children. In the past few years, topical beta-blockers (bBs) have been reported to be an effective treatment of superficial IHs. Objective: We sought to evaluate the clinical effectiveness and safety profile of enhanced percutaneous delivery of bBs for the treatment of IH. Methods: A retrospective study of all cases of IHs treated with enhanced percutaneous delivery of bBs between 2018 and 2019 was performed. Epidemiologic, clinical, and treatment data, including effectiveness score and safety, were reviewed. Results: The study included 11 patients with a total of 11 IHs. Of the total number of IHs, 7 (63.7%) showed a good response to treatment and 4 (36.3%) had a partial response; thus all patients (100%) had good or partial response to treatment. No systemic or local adverse effects were reported. Limitations: This is an uncontrolled retrospective study. Conclusion: Enhanced percutaneous delivery of bBs is a safe and efficient topical therapy for IH.
