Patch Testing With Formaldehyde 2.0% (0.60 mg/cm2) Detects More Contact Allergy to Formaldehyde Than 1.0.

Background: The International Contact Dermatitis Research Group increased the patch test concentration of formaldehyde from 1.0% aqueous (aq) to 2.0% aq (in 2011).

A Real-World, Non-interventional Indian Study Evaluating Intensive Plant-Based Butter Moisturizing Cream in Psoriasis.

Introduction: Psoriasis is estimated to affect 0.44-2.8% of the Indian population.

Real-World, Non-Interventional, Observational Study of Hydroxyzine Hydrochloride in Chronic Pruritus: a Prospective, Non-Comparative Study.

Introduction: Although hydroxyzine is widely used for symptom relief in pruritus, its clinical safety and efficacy data in the Indian setting are scarce. We conducted a study to assess the effectiveness and tolerability of hydroxyzine in the management of Indian patients with chronic pruritus in a real-world setting.

Methods: This was a prospective, observational, patient-reported outcomes (PRO) study in patients with chronic pruritus due to dermatological causes treated with hydroxyzine as per the clinician's discretion for a period of up to 12 weeks.

Multicenter Patch Testing With Methylchloroisothizoline/Methylisothiazolinone in 100 and 200 ppm Within the International Contact Dermatitis Research Group.

Background: The preservative methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) is a well-known contact sensitizer. Historically, there have been different opinions on the optimal patch test concentration of MCI/MI, and both 0.01% and 0.

Multicenter Patch Testing With Methylisothiazolinone and Methylchloroisothiazolinone/Methylisothiazolinone Within the International Contact Dermatitis Research Group.

Background: The preservatives methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) and MI are well-known contact sensitizers. Recently, an increase in the contact allergy frequency for MI 0.2% aqueous (aq) has been seen in many European countries paralleled with an increase in MCI/MI allergy.

Utility of high-frequency ultrasonography in the diagnosis of benign and malignant skin tumors.

Various benign and malignant tumors may arise from the skin. These may be of epidermal, dermal, subcutaneous or appendageal origin. Skin biopsy is the gold standard for diagnosis of skin tumors.

Proposed ICDRG Classification of the Clinical Presentation of Contact Allergy.

The International Contact Dermatitis Research Group proposes a classification for the clinical presentation of contact allergy. The classification is based primarily on the mode of clinical presentation. The categories are direct exposure/contact dermatitis, mimicking or exacerbation of preexisting eczema, multifactorial dermatitis including allergic contact dermatitis, by proxy, mimicking angioedema, airborne contact dermatitis, photo-induced contact dermatitis, systemic contact dermatitis, noneczematous contact dermatitis, contact urticaria, protein contact dermatitis, respiratory/mucosal symptoms, oral contact dermatitis, erythroderma/exfoliative dermatitis, minor forms of presentation, and extracutaneous manifestations.

Keratoelastoidosis marginalis of the hands: A report in two farmers.

Keratoelastoidosis marginalis of the hands (KEMH) is a distinct solar elastotic dermatosis belonging to the group of marginal keratoderma. It is characterized by linear plaques on the hand and calcified dermal elastotic masses predominantly affecting the radial side of the index finger, first web space, and ulnar side of the thumb. It is predominantly seen in the middle-aged and elderly age group.

The story of a deformed leprous foot.

Eccrine syringofibroadenoma (ESFA) is a rare adnexal tumour of eccrine ductal proliferation. A 50 year old treated case of leprosy presented with a chronic non healing ulcer of 5 years duration on the deformity laden right foot. Multiple verrucous papules and plaques were seen surrounding the ulcer which showed histopathological findings consistent with ESFA.

Multiple Cutaneous Reticulohistiocytoma.

Multicentric reticulohistiocytosis is a rare non-Langerhans cell histiocytosis characterized in its full form by severe destructive arthritis, cutaneous nodules, and systemic manifestations. Cutaneous lesions may precede, accompany, or more commonly develop later than other features in this disease. We describe a case of multiple cutaneous reticulohistiocytoma without any systemic associations after thorough investigations.

Multicenter Patch Testing With a Resol Resin Based on Phenol and Formaldehyde Within the International Contact Dermatitis Research Group.

Background: Contact allergy to phenol-formaldehyde resins (PFRs) based on phenol and formaldehyde is not detected by a p-tertiary-butylphenol-formaldehyde resin included in most baseline patch test series.

Objective: The aims of this study were to investigate the contact allergy rate to PFR-2 in an international population and to investigate associated simultaneous allergic reactions.

Methods: Thirteen centers representing the International Contact Dermatitis Research Group included PFR-2 into their patch test baseline series during a period of 6 months in 2012.
