Summary
A patient developed a rash on his left wrist that spread to the right. Investigations explored whether a chrome-colored watch caused the allergic contact dermatitis or if another irritant was responsible.
Area of Science:
- Dermatology
- Allergology
Background:
- Contact dermatitis is a common skin condition.
- Allergic contact dermatitis (ACD) is triggered by specific allergens.
Observation:
- A patient presented with a rash initially on the left wrist, subsequently spreading to the right wrist.
- The rash's location suggested a potential link to external factors, such as jewelry.
Findings:
- Patch testing is crucial for identifying specific allergens causing ACD.
- Nickel, a common component of chrome plating, is a frequent cause of allergic reactions.
Implications:
- Accurate diagnosis of contact dermatitis is essential for effective management.
- Identifying the causative agent allows for avoidance and prevention of future reactions.

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

01:27Assessment of the Cardiovascular System III: Palpation
1.4K
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:15Reticular Dermis
5.4K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
