[Management of chronic ulcers: punch grafting].

Chronic ulcers are a common but important dermatological problem and a major source of expense in the western countries. Skin graft is a surgical procedure in which skin or skin substitute is transplanted in order to close a wound. This article aims to review the different categories of grafts, their indications for the healing of chronic ulcers of the lower limbs, emphasizing the position of punch grafts in the treatment arsenal.

Lichen aureus with pseudolymphomatous infiltrate.

Lichen aureus is a variant of pigmented purpuric dermatoses. The usual histopathology of lichen aureus is characterized by a subepidermal dense, band-like lymphocytic infiltrate, extravasated erythrocytes, and hemosiderin deposits. We report three patients with lichen aureus on the extremities with similar clinical, dermoscopic, and histopathological findings characterized by a dense band-like relatively deep dermal infiltrate accompanied by extravasation of erythrocytes and hemosiderin deposits occasioning a resemblance to a lymphoproliferative disorder.

Compression Stocking With 100% Donning and Doffing Success: An Open Label Randomised Controlled Trial.

Objective: The aim of this study was to test whether an investigational two layer stocking exerting 27-29 mmHg pressure at the medial supramalleolar level, but without compression in the foot and heel, is easier to put on and take off than a standard stocking of the same compression class (23-32 mmHg), and also to assess the prevention of diurnal oedema with both types of stocking.

Methods: This was an open label randomised controlled trial, which included 47 patients. All participants were at least 65 years of age and suffered from chronic venous disease class C3 - C6 in one leg.

Buffered lidocaine 1%/epinephrine 1:100,000 with sodium bicarbonate (sodium hydrogen carbonate) in a 3:1 ratio is less painful than a 9:1 ratio: A double-blind, randomized, placebo-controlled, crossover trial.

Background: Neutralizing (buffering) lidocaine 1%/epinephrine 1:100,000 solution (Lido/Epi) with sodium hydrogen carbonate (NaHCO) (also called sodium bicarbonate) is widely used to reduce burning sensations during infiltration of Lido/Epi. Optimal mixing ratios have not been systematically investigated.

Objectives: To determine whether a Lido/Epi:NaHCO mixing ratio of 3:1 (investigational medicinal product 1) causes less pain during infiltration than a mixing ratio of 9:1 (IMP2) or unbuffered Lido/Epi (IMP3).

[Leg ulcers (ulcus cruris): The frequent macrovascular causes].

Leg ulcers (ulcus cruris): The frequent macrovascular causes Four pathologies make up the macrovascular etiologies of leg uclers: Venous leg ulcers (50 %), mixed venous-arterial leg ulcers (20 %), arterial leg ulcers (5 %), and Martorell hypertensive ischemic leg ulcer (5 %). The remaining 20 % concern a large array of other etiologies. Every leg ulcer requires vascular (arterial and venous) work-up, that can be completed with microbiology, biopsy, and more in-depth internal diagnostics, as indicated.
