Physical Properties of Amines

Physical Properties of Amines

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Accessory Structures of the Skin: Hair and Hair Follicles

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Assessment of the Rectum and Anus

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Area of Science:

Gastroenterology and Proctology
Dermatology

Background:

Anal pruritus is a prevalent anorectal symptom with significant quality of life implications, often leading to delayed medical consultation due to embarrassment.
Causes are diverse, ranging from idiopathic to secondary factors including anorectal diseases, cancers, dermatological conditions, infections, and systemic diseases.

Discussion:

Colonoscopy offers a critical opportunity for perianal area evaluation, aiding in the diagnosis of underlying conditions.
The Washington classification is a key tool for categorizing perianal skin abnormalities.
Digital anorectal examination and anoscopy are crucial for excluding anorectal diseases and masses.

Key Insights:

Endoscopists must recognize common etiologies of anal pruritus and document perianal findings in colonoscopy reports.
A comprehensive treatment strategy includes meticulous hygiene, irritant avoidance, and protective skin care.
Topical treatments such as steroids, capsaicin, tacrolimus, and methylene blue injections offer therapeutic options.

Outlook:

Further research into standardized diagnostic criteria and novel therapeutic interventions for anal pruritus is warranted.
Integrating perianal assessment into routine colonoscopy protocols can improve patient outcomes.
Patient education on proper hygiene and irritant avoidance is essential for managing this condition.
