Dermatologists are often faced with the challenge of patients presenting with non specific symptoms such as itching and or erythema. These symptoms may be attributed to a number of diseases, many of which are trivial, and others even life-threatening. In order to establish the correct diagnosis, dermatologists must rely on good diagnostic tools and knowledge. Dermoscopy was introduced mainly for inspection of pigmented lesions, but its use has now also spread to non-melanoma skin cancer, inflammatory diseases, and almost any skin disease...

Chronic or episodic severe itch is recurrent in atopic dermatitis (AD). Non-histaminergic neuronal itch pathways are suggested to dominate in AD itch, contributing to an "itch-scratch-itch cycle" that prolongs and worsens itch, pain, and skin lesions. We hypothesized that non-histaminergic neuronal sensitization contributes to itch in AD. Hence, we compared sensitivity to thermal, mechanical, and chemical pruritic stimuli in AD patients and controls. The study comprised 25 AD patients with chronic itch and 25 healthy controls...

The sensation of itching can be defined as "an unpleasant cutaneous sensation that provokes a desire to scratch." The perception of itching is not critical for the maintenance of life, but persistent itching can be extremely irritating and decreases the quality of life. Crotamiton (N-ethyl-o-crotonotoluidide) has been used as an anti-itch agent for humans for around 70 years. In spite of the long use of crotamiton, its mechanism of action remains unknown. We hypothesized that crotamiton might have effects on transient receptor potential (TRP) channels expressed in the peripheral nervous system and the skin...

BACKGROUND: There is great diversity in reported post-operative outcomes for otoplasty, with the incidence of haematoma or infection ranging from 0% to 15.6% and 0%-10%, respectively. With such variability, it is difficult to determine an overall 'average' incidence of common post-operative complications. METHODS: A systematic review of the most relevant medical databases was conducted for studies available in English published between January 1, 2000, and December 31, 2015...

A skin care regimen which significantly improved atopic dermatitis and pruritus was evaluated for its efficacy and acceptability in senior subjects diagnosed with xerosis who also suffer from pruritus. This was an open-label, single-center study, designed to evaluate the daily use of a skin care regimen for 15 days. Assessments were made at baseline, day 8 and day 15 for visual skin dryness, transepidermal water loss (TEWL), hydration, desquamation, subject-perceived itch and quality of life (QoL). Twenty-five subjects, ages 60-73 years, had significantly improved skin visual dryness, hydration, desquamation, itch and QoL at days 8 and 15, relative to baseline (P < ...

We report the case of a 29 year old pregnant female who experienced itching with erythematous plaques on prophylactic enoxaparin for recurrent fetal losses. These lesions generalized on rechallenge but erythema and itching gradually resolved after 4 weeks of discontinuation. Cutaneous adverse events with heparin have been reported (Villanueva et al. in Actas Dermosifiliogr 103:816-819, 2012; Neloska et al. in Acta Dermatovenerol Croat 23:223-224, 2015; Maldonado et al. in Clin Exp Dermatol 37:707-711, 2012; Schindewolf et al...

BACKGROUND: Graft-versus-host disease (GVHD) is a common complication of hematopoietic stem cell transplantation. Skin barrier disruption could induce thymic stromal lymphopoietin (TSLP) expression, and the expression of TSLP was increased in lesions of atopic dermatitis (AD)-like GVHD and lichen planus (LP)-like GVHD. This study attempted to investigate the skin barrier function of AD-like GVHD and LP-like GVHD and possible mechanisms. METHODS: Eighteen AD-like GVHD patients, 12 LP-like GVHD patients, and 14 healthy volunteers were enrolled in this study...

Itch, or pruritus, is a hallmark feature of atopic dermatitis (AD). The impact of AD-related pruritus can range from mildly distressing or distracting to completely disabling. Traditionally, management of itch in AD patients has focused on restoring the altered skin barrier with topical emollients and/or reducing inflammation. A growing emphasis has been placed on directly targeting the neural transmission pathways that mediate itch signaling. Off-label use of neuromodulatory agents has helped reduce this aggravating symptom in atopic patients...

BACKGROUND AND PURPOSE: The transient receptor potential vanilloid 3 channel (TRPV3) is a heat-sensitive ion channel which is predominantly expressed in keratinocytes. TRPV3 is involved in multiple physiological and pathophysiological processes within the skin, including cutaneous nociception, temperature sensation, and the development of itch. The role of TRPV3 in such processes is only poorly understood, therefore, the establishment of selective modulators of TRPV3 channels is highly desirable...

Chronic urticaria is an itching skin disease which persists for more than 6 weeks. Chronic urticaria has great impact on the daily life of the patient, and the fluctuating nature of the symptoms complicates the monitoring and treatment of the disease. Currently, there are no reliable biomarkers to identify and measure disease activity in chronic spontaneous urticaria. Consequently, use of patient-reported outcomes (PROs) is crucial when evaluating and monitoring different aspects of chronic urticaria such as disease activity/severity, disease control, and quality of life...

M Sticherling
The scalp may be affected by various diseases with equally varying manifestations. Erythema and scaling is often accompanied by agonizing itch. Scalp psoriasis and seborrheic eczema represent the most frequent diseases, which can be differentiated into classical cases; however, overlap and similarities are seen. Sharply demarcated erythematosquamous plaques across the natural hairline in psoriasis are opposed to blurred dark-red erythema and yellowish, greasy scales in seborrheic eczema. Whereas with the latter diffuse alopecia may frequently be found, hair loss is rarely seen in psoriasis and may also be related to therapeutic agents...

There is little information on herpes zoster infection in breast cancer patients as a complication during adjuvant chemotherapy. We report a case of herpes zoster in a 65-year-old woman presented with low grade fever and vital signs together with skin symptoms such as severe edema, irritation and itching in the left breast where there was wound drainage. PCR test revealed varicella zoster virus. To the best of our knowledge, the histologic features coupled with PCR led to a diagnosis of herpes zoster.

INTRODUCTION: Local heat urticaria is a physical urticaria caused by the environmental stimulus of heat. Typically, the resultant lesion, a wheal, is pruritic (itches) and is sometimes accompanied by a burning sensation. It is a self-limited phenomenon that resolves after 1.5-2 h. The prevalence of local heat urticaria in the general population has been estimated as 1 in 200,000 persons. CASE REPORT: The subject, a 39-yr-old active duty man, participated in a test of a 95-GHz energy beam designed to heat the skin...
