Oral Provocation Testing in Cutaneous Adverse Drug Reactions to Antiretroviral and Antitubercular Therapy: A Study at a Tertiary Care Hospital in South India.

Aim: To collect data pertaining to oral drug provocation testing (DPT) in hospitalized patients with antiretroviral (ARV)/antitubercular agent-induced rashes.

Methods: Patients with cutaneous adverse drug reactions (ADRs) to ARV/antitubercular drugs and who underwent oral DPT during a 5-year period were included in this study.

Results: Data were collected from the records of 21 patients.

An Open-Label Randomized Multicenter Study Assessing the Noninferiority of a Caffeine-Based Topical Liquid 0.2% versus Minoxidil 5% Solution in Male Androgenetic Alopecia.

Background: Androgenetic alopecia is a condition with a high prevalence worldwide and affects both males and females. Currently, only 2 approved treatments exist: finasteride (males only) and minoxidil 2 or 5% solution (males and females).

Methods: We conducted a randomized, open-label, multicenter noninferiority study to determine whether a caffeine-based 0.

An interesting case of Lucio phenomenon triggered by activation of hepatitis C infection.

Lucio phenomenon (LP) or erythema necroticans is a rare type of reaction pattern found in untreated patients with diffuse non-nodular leprosy. It is important to distinguish this from vasculonecrotic erythema nodosum because thalidomide with high-dose steroids is the mainstay of treatment for the latter, whereas LP shows no response to thalidomide. We report a case of a 60-year-old man who presented with purpuric patches, hemorrhagic blisters, and ulcers over extremities of 15 days duration.

Addisonian pigmentation and vitamin B₁₂ deficiency: a case series and review of the literature.

Skin changes associated with vitamin B₁₂ deficiency are common. In most cases, patients present primarily with systemic involvement (eg, megaloblastic anemia and/or neurologic effects), and additional cutaneous changes related to the diagnosis are noted as incidental findings. The role of vitamin B₁₂ deficiency in the etiology of Addisonian pigmentation has not been well studied.

Anaplastic lymphoma kinase-positive primary cutaneous anaplastic large cell lymphoma--is it a new variant?

Anaplastic large cell cutaneous lymphomas are clinically and pathologically heterogeneous, CD30 + (Ki-1) lymphoproliferative disorders. The importance of anaplastic lymphoma kinase (ALK) positivity is well known in the prognosis of primary systemic anaplastic large cell cutaneous lymphomas; however, the same in primary cutaneous anaplastic large cell cutaneous lymphomas is not much clear. Herein we report a 65-year-old male with an 18-month history of minimally pruritic localized nodulo-plaque lesion over lower back.
