"Azole menace"-An underappreciated trigger perpetuating the epidemic of antifungal therapeutic failure in cutaneous mycoses.

The South-Asian epidemic of anti-fungal therapeutic failures (AFTF) is on the rise. Although many demographic, environmental, and socioeconomic factors have been implicated in the genesis of this problem, two pharmacological issues warrant attention. While detailed discussions on the role of topical corticosteroid (TCS) in the changing landscape of the superficial mycotic infections in this region have been making headlines, another equally, rather more important pharmacological factor seems to have been undermined by the hype around TCS. The fastidious pharmacokinetic properties and related practical aspects of the triazole group of oral and topical antifungals, especially oral itraconazole seem to contribute significantly to the persistence of AFTF epidemic. In this paper, we shall discuss the broad aspects of the spectral precariousness of oral triazole antifungals with special emphasis to itraconazole, a concept known as the "azole menace" in the overall pathogenesis and tenacity of the AFTF epidemic.

Application of mucous membrane dermoscopy (mucoscopy) in diagnostics of benign oral lesions - literature review and preliminary observations from International Dermoscopy Society study.

Dermoscopy of mucosal surface termed "mucoscopy" is an upcoming offshoot of dermatological imaging. However, the literature on mucoscopy is limited to individual cases and small case series. An organized review or systematic analysis of mucoscopy is lacking. The aim of this review was to summarize the published literature on mucoscopic features of benign conditions affecting the oral mucosa and semi-mucosa. Additionally, the results of mucoscopic features of diseases, which have not been described before have been presented.

A comparative study of topical tacrolimus and topical triamcinolone acetonide in nodular scabies.

The aim of this study was to compare the efficacy and safety of 0.1% triamcinolone acetonide and 0.03% tacrolimus ointment for the treatment of nodular lesions of scabies. In this double-blind randomized controlled trial, 50 Indian men with postscabeitic persistent nodular lesions (labelled to have nodular scabies (NS)/postscabies prurigo (PSP)) over the external genitalia, were enrolled. They were randomized into two groups to receive either a mid-potency topical corticosteroid (TCS); triamcinolone acetonide 0.1% ointment twice daily, or topical calcineurin inhibitor (CNI); tacrolimus ointment 0.03% twice daily over the nodular lesions for 2 weeks. All patients were followed up on three visits: 1, 2, and 6 weeks, for assessment. Efficacy was evaluated by 5-point range investigator-assessed VAS, and a 4-point severity of pruritus scale (SPS) score. The mean VAS score was higher in triamcinolone group compared to tacrolimus group at both follow-ups, although statistically significant only at 2nd week visit. The fall in mean SPS at both follow-ups was also higher in the steroid group, but the difference was not statistically significant. While, the overall tolerance to either ointment was excellent, mild hypopigmentation, and epidermal atrophy were detected on dermoscopic evaluation of the treated areas at the 2nd week visit in a small subset of patients in the triamcinolone group. The frequency of relapse of lesions and/or pruritus after four weeks of the 2-week therapy was high in both the groups (higher in tarolimus group). Conclusively, although both treatment options provided safe and satisfactory short term improvement, the results from this study suggest an overall higher efficacy of a mid-potency TCS like triamcinolone 0.1% over topical CNI like tacrolimus 0.03%, in the short-term treatment of nodular lesions of NS/PSP. Topical CNIs may be considered for maintenance of effect, if prolonged therapy is warranted.

Efficacy of topical latanoprost in the treatment of eyelid vitiligo: A randomized, double-blind clinical trial study.

Numerous studies have demonstrated that the pigmentation of iris and around the eyelid is a common side effect of latanoprost, a prostaglandin F2alpha analogue used in the treatment of glaucoma. Hence, the authors decided to study the effectiveness of topical latanoprost on vitiligo patches around the eyelid. In this randomized, double-blind, clinical trial study, 31 patients with vitiligo vulgaris and focal vitiligo involving the eyelids were evaluated. Patients were randomly divided into two groups. First group received topical latanoprost gel twice daily for 12 weeks, whereas the second group received placebo with the same protocol. To evaluate severity of the disease the VIDA rating system was used. Serial photos of the patches were taken to compare and evaluate the repigmentation percentage of the patches. The patients in both groups had almost similar VIDA score (p > .05). First group showed improved pigmentation, whereas participants in the second group did not show any improvement in the pigmentation. The group treated with latanoprost showed significant reduction in the symptoms of the disease, whereas those treated with placebo did not show any alteration (p > .05). No significant complications were observed in either groups. Latanoprost proved effective in treating vitiligo disease involving eyelids.

Pityriasis Lichenoides Chronica in a Patient With Ankylosing Spondylitis Treated With Etanercept.

BACKGROUND: Pityriasis lichenoides chronica, a papulosquamous disorder often considered a subtype of pityriasis lichenoides. It is considered a clonal T-cell disorder, which may be associated with cutaneous T-cell lymphoma that may develops in response to foreign antigens. CASE PRESENTATION: We present a 38-year-old male patient with ankylosing spondylitis who was on treatment with etanercept. After 8 weeks of treatment, the patient presented with scaly erythematous papules, on the back and arms. He was diagnosed clinically with pityriasis lichenoides chronica. CONCLUSION: Pityriasis lichenoides chronica should be included among the broad clinical spectrum of chronic inflammatory skin diseases which may occur during treatment with TNF-alpha antagonists.

Pityriasis Lichenoides Chronica in a Patient With Ankylosing Spondylitis Treated With Etanercept.

Pityriasis lichenoides is a scarce cutaneous disorder with unknown etiology. It contains a range of clinical manifestations including acute papular lesions that quickly grow into pseudo vesicles and central necrosis to small, scaling, benign-appearing papules.1,2.

Intralesional vitamin D immunotherapy for recalcitrant molluscum contagiosum.

Molluscum contagiosum (MC) is a benign viral infection, which may have florid manifestations in immunosuppressed patients. Moreover, the treatment is often unsatisfactory in these patients and it maybe recalcitrant. We hereby report the use of intralesional vitamin D immunotherapy in two immunosuppressed patients with persistent widespread MC lesions.

Folie a deux and delusional disorder by proxy: an atypical presentation.

Delusion of parasitosis is a rare condition characterised by an individual harbouring the delusion of being infested with insects or parasites. We report a rare and interesting case of delusion of parasitosis presenting as folie a deux, that is, the delusion is shared by both the parents of an 18-month-old child, with proxy projection of parental delusion on the child. The case highlights the rare concomitant occurrence of two psychocutaneous disorders and emphasizes the importance of early recognition and appropriate intervention to safeguard the well-being of the child.

Smegma Pearls in Young Uncircumcised Boys.

Deposition of smegma in the subpreputial region is common in young uncircumcised boys. Although the term "smegma pearls" has been used colloquially for this entity, there is an apparent lack of reference to smegma pearls and their characteristics in the extant scientific literature. We present a series of six Indian boys with smegma pearls and discuss their possible origin, course, and management.
