Abstract:
A 79-year-old woman presented with symmetric, fixed erythematous patches on the hypothenar eminences of both palms, present for over 30 years, with finely visible telangiectasias. Initially asymptomatic, the lesions later caused stinging discomfort. Her occupational history revealed 24 years of daily use of a pneumatic pinner, alternately held in each hand, causing repetitive pressure on those palm areas. Investigations excluded systemic causes of palmar erythema, and laboratory findings were normal. Similar lesions termed 'computer palms' have been described in chronic keyboard users, attributed to pressure-induced vascular changes. We propose the broader term 'pressure palms' to encompass analogous lesions caused by chronic mechanical stress in any occupational context. This case illustrates that sustained localized mechanical factors can induce permanent vascular and dermal changes, often overlooked, and underscores the need for dermatologic surveillance and preventive ergonomic measures in susceptible occupations.

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...
