Article Synopsis
  • Chondrodermatitis nodularis helicis is a benign inflammatory condition marked by a painful nodule on the ear, often caused by pressure.
  • The first-line treatment is relieving pressure, which can be combined with steroid injections if needed.
  • If the issue persists, a surgical removal of faulty cartilage—without excising skin—is preferred due to its effectiveness and lower chance of recurrence compared to traditional methods.

A lack of understanding about the distinction between incontinence-associated dermatitis and pressure sores leads to inadequate treatment and therefore a higher incidence of pressure sores. Pressure relief may not be adequately carried out due to concentration exclusively on treatment of incontinence. In this article we will discuss the multifactorial approach, based on 2 patient cases.

Daivobet (Dovobet) is a fixed combination ointment of calcipotriol and betamethasone dipropionate. The real-life clinical use of calcipotriol/betamethasone dipropionate treatment was assessed in this multi-centre, single-group, non-interventional study. Patients with psoriasis vulgaris who had a recent calcipotriol/betamethasone dipropionate prescription prior to the study start evaluated their satisfaction with the treatment after a 4-week course and after repeated courses for up to 6 months.

Epidermodysplasia verruciformis (EV) is a rare heritable disease characterized by an unusual susceptibility to infection with specific types of human papillomavirus and a propensity for developing skin malignant tumors. Partial defects in cell-mediated immunity have been demonstrated in this disease. Here, we describe a patient with EV who was treated unsuccessfully with imiquimod.

Background: Although guidelines advise against massage, it is one of the methods widely regarded and used by nurses to prevent pressure ulcers (PU).

Objectives: The purpose of this study was to examine the effectiveness of different variations of massage in preventing pressure ulcers.

Methods: A randomized, double-blind cross-over design, in which patients of nursing homes who are prone to PU underwent two of the three possible interventions; 'position changes only', 'massaging with an indifferent cream' and 'massaging with a dimethyl sulfoxide (DMSO) cream'.

Objective: Pressure ulcers are classified into 4 distinct stages, which allows comparisons between institutions and even countries. Recently, attempts have been made to single out so-called moisture lesions from the early stages of pressure ulcer lesions as a distinct entity.

Methods: To investigate the justification for this development, 14 histopathologic samples from patients with both incontinence and pressure ulcer lesions were studied in an attempt to delineate differences in the pathophysiology and histopathology.

Introduction: Although several controlled clinical trials have demonstrated the efficacy and good tolerability of 1% pimecrolimus cream for the treatment of atopic dermatitis, the results of these trials may not apply to real-life usage. The objective of this study was to evaluate the safety and efficacy of a pimecrolimus-based regimen in daily practice.

Methods: This was a 6-month, open-label, multicenter study in 947 patients aged >or=3 months with atopic dermatitis of all severities.
