Summary
Occupational pressure can cause persistent skin changes on the palms, termed 'pressure palms'. This condition results from sustained mechanical stress, highlighting the need for ergonomic awareness in certain jobs.
Area of Science:
- Dermatology
- Occupational Medicine
- Vascular Biology
Background:
- Palmar erythema can manifest as persistent skin changes.
- Repetitive mechanical stress is implicated in localized vascular alterations.
Purpose of the Study:
- To describe a case of chronic palmar erythema due to occupational pressure.
- To propose the term 'pressure palms' for lesions caused by sustained mechanical stress.
- To emphasize the role of occupational factors in dermatologic conditions.
Main Methods:
- Clinical case presentation of a 79-year-old woman.
- Detailed occupational history focusing on repetitive hand pressure.
- Exclusion of systemic causes for palmar erythema through investigations.
Main Results:
- Symmetric, fixed erythematous patches with telangiectasias on hypothenar eminences, present for over 30 years.
- Lesions evolved from asymptomatic to causing stinging discomfort.
- Occupational history revealed 24 years of pneumatic pinner use, causing repetitive palm pressure.
Conclusions:
- Sustained localized mechanical factors can induce permanent vascular and dermal changes.
- 'Pressure palms' is proposed as a term for lesions from chronic occupational mechanical stress.
- Dermatologic surveillance and preventive ergonomic measures are crucial for susceptible occupations.

01:15Handwashing III: During the Procedure and Post-Procedure Steps
To wash hands properly, follow these steps:
01:23Hand hygiene
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:20Personal Protective Equipment
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:
01:16Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
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,...

01:19Handwashing II: Pre-procedure and Initial Procedure Steps
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
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...

01:22PPE Use in Healthcare Settings I: Donning
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...
