Blue light has garnered attention because of its ability to penetrate more deeply into the skin layers, and induce cellular dysfunction and DNA damage. Photoageing, hyperpigmentation and melasma are some of the cutaneous changes that develop on exposure to blue light. To date, the therapeutic roles of blue light have been evaluated in dermatological conditions like psoriasis, eczema, acne vulgaris, actinic keratosis and cutaneous malignancies, among others. In this review, we have attempted to present an evidence-based compilation of the effects of blue light on the skin. [ABSTRACT FROM AUTHOR]

Hidradenitis suppurativa (HS) is a chronic, inflammatory condition of the pilosebaceous unit. The typical patient with HS is characterized as someone with obesity, who smokes and who has nodules, abscesses and/or draining tunnels predominantly distributed in intertriginous skin. It has been established that lifestyle and genetic factors are the main pathophysiological drivers of HS. In this critical review, we explore the interrelatedness of meta-inflammation, obesity and HS and discuss if and how this relationship may be manipulated for a therapeutic end.

Dermatophytosis is one of the leading causes of visits to the dermatology department, especially in India, where the hot and humid climate favours fungal acquisition and perpetuation. Usual modalities of treatment include the use of either oral or topical antifungals or a combination of both, depending on the severity and extent of infection as well as the type of causative organism. But recently, steroid-modified dermatophytosis, an iatrogenically perpetuated dermatophytosis caused by the indiscriminate use of topical corticosteroids has emerged as a troublesome epidemic. We planned a cost-of-illness analysis of superficial dermatophytosis comparing the direct healthcare costs in steroid-naive and steroid-modified dermatophytosis. In our study, the average total cost of treatment for steroid-naive and steroid-modified dermatophytosis was found to be rupees (Rs) 2172.42 and Rs 3770.61 respectively, meaning that the cost for patients who used topical steroids is an additional 40% on average for treatment, when compared with the cost for patients who are steroid naive. The need for more consultations, investigations (relating to atypical presentation) and extended duration of treatment with higher-grade antifungals were found to contribute to the increased financial burden in steroid-modified dermatophytosis.

Tyrosine kinase inhibitors (TKIs) target the signal transduction pathways of protein kinases by several modes of inhibition. Adverse effects are generally dose dependent, with certain side-effects unique to each drug. However, due to similarities in target sites, different classes of TKIs may have identical or overlapping side-effect profiles. This narrative review is an attempt to summarize the common and uncommon adverse effects of different classes of TKIs. [ABSTRACT FROM AUTHOR]

The diverse world of dermatology has a wealth of protracted and at times tenuous names encompassing disease conditions, characteristic clinical descriptions and signs, among others. Many dermatological entities are identified by toponyms or place names. Although some sound irrelevant and archaic (with only historical importance reminding us of the lively history of the subject), other terminologies aid in easy recollection. In this review, we have succinctly summarized various toponymous description in dermatology covering diseases, signs, scales, criteria and treatments. [ABSTRACT FROM AUTHOR]

Multisystem inflammatory syndrome in adults (MIS‐A) is an inflammatory condition that affects multiple extrapulmonary organ systems (cardiac, gastrointestinal tract, dermatological and/or neurological), attributed to a postinfectious and atypical complication occurring weeks to months after infection with severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2). The diagnosis is primarily based on findings encompassing persistent fever, elevated inflammatory markers, multiorgan involvement and a temporal relationship with COVID‐19 infection. The existing literature on MIS‐A, although growing, is limited to case reports and small case series. It is imperative that dermatologists be aware of this entity and aid the critical care team to ensure timely diagnosis and early therapeutic intervention. In this review, we concisely highlight the varied presentations, pathogenesis and treatment options in MIS‐A. [ABSTRACT FROM AUTHOR]

The various types of steroid preparations seen in our patient cohort were administered by unqualified medical professionals primarily for the patient's cutaneous disease, rather than for any suggestion of an underlying medical condition for which the steroid use could be justified. Clinical examination and biochemical derangement in the hypothalamic-pituitary axis were suggestive of iatrogenic hypercorticolism in 4 of 17 patients (23.5%); we referred these cases (Patients 12, 13, 15 and 17) to an endocrinologist for specialized management. A pilot study to evaluate the patient adherence to antifungal therapy in dermatophytosis: a possible contributory factor to the current epidemic-like situation in India. [Extracted from the article]

Obese and overweight individuals may have a wide spectrum of cutaneous features and can have more severe manifestations of multiple dermatological conditions. There have been multiple expert opinions on the role of weight loss, in the improvement of skin conditions. There have been few studies over the past decade evaluating the effects of exercise and other modes of weight reduction on various dermatoses such as psoriasis, acne vulgaris, hidradenitis suppurativa and acanthosis nigricans. In this review, we have attempted to provide a summary of the beneficial effects of weight loss on various dermatological conditions. [ABSTRACT FROM AUTHOR]

Sexually transmitted infections (STI) constitute a major share of the diseases encountered by physicians. Although science has made considerable progress in terms of diagnosing and treating such infections, development of effective and safe vaccines is still needed. Syphilis, viral warts, gonorrhoea, genital herpes, chlamydia and trichomoniasis are the most common infections that are transmitted sexually. In this review, we have attempted to summarize the current status, lacunae and avenues for future research, with reference to the development of STI vaccines. [ABSTRACT FROM AUTHOR]

Summary: Chronic venous disease (CVD) is a common medical condition that results from venous hypertension of the limbs, leading to significant morbidity. The diagnosis is quite straightforward from patient history and obvious clinical manifestations. In the recent past, the availability of various invasive and noninvasive treatments has assisted in evaluation of such cases. Although compression therapy is the mainstay of management, newer surgical and other interventional techniques are now being considered for patients who do not respond to conventional medical management. The second part of this two‐part review article will outline a diagnostic approach in cases of CVD and discuss the management principles encompassing conservative, pharmacological and interventional options.

Summary: Chronic venous disease (CVD) is a commonly encountered condition in the dermatology outpatient department. If untreated, CVD may progress to chronic leg ulcer causing serious morbidity to the patient. It also affects the quality of life of the affected patient and contributes to loss of work productivity. The spectrum of clinical manifestations for CVD is myriad, ranging from asymptomatic varicose veins and pigmentation to ulceration and scarring. Awareness of spectrum of clinical presentations is required to identify, diagnose and manage CVD. Long‐standing cases may develop ankle joint stiffness, fixed flexion deformity, periostitis and even Marjolin ulcer. Increased venous hypertension, thought to result from valve incompetence and failure of the calf muscle pump, is central to the pathophysiology of the development of CVD. Tissue oedema, hypoxia and subsequent fibrosis are major immediate contributing factors responsible for the clinical manifestations of CVD. Localized, chronic inflammation is now increasingly being recognized as a key player, directly responsible for stasis dermatitis and hypercoagulable state. The complete ramifications of persistent inflammation in CVD are yet to be understood and serious systemic morbidities such as arterial and cardiac disease are increasingly being recognized in association with CVD.

Tofacitinib has revolutionized the treatment of numerous dermatological conditions in different age groups. However, evidence for its effectiveness, safety and tolerability in the paediatric population is limited. We performed a literature search, which showed that oral tofacitinib is a reliable option in refractory juvenile dermatomyositis, severe alopecia areata, atopic dermatitis and psoriasis. Topical tofacitinib is an effective option in vitiligo and halo naevus. The risk–benefit ratio should be assessed prior to consideration of this molecule. In this narrative review, we have attempted to present a summary of the evidence of using tofacitinib (oral and topical) in paediatric dermatoses. [ABSTRACT FROM AUTHOR]

A pilot study to evaluate the patient adherence to antifungal therapy in dermatophytosis: a possible contributory factor to the current epidemic-like situation in India Patients (37%) with localized dermatophytosis had higher adherence levels than those with disseminated disease (25%); 54% of patients with disseminated dermatophytosis had low adherence, and the difference was statistically significant ( SP 2 sp I P i = 0.048). Of the 236 patients prescribed both oral and topical antifungals, mean adherence scores were 6.41 for topical and 6.82 for oral antifungal drugs; the score was significantly higher for oral antifungals, and the difference was statistically significant (paired I t i -test, I P i < 0.001).
