|May 3, 2021
Summary
The Koebner phenomenon describes new psoriatic lesions appearing after skin injury. Recognizing this response to trauma aids in early psoriasis diagnosis.
Area of Science:
- Dermatology
- Pathophysiology
Background:
- The Koebner phenomenon is a dermatological response where skin trauma induces characteristic lesions.
- While not exclusive to psoriasis, it can manifest as new psoriatic plaques following injury.
Purpose of the Study:
- To highlight the significance of the Koebner phenomenon in the context of psoriasis diagnosis.
- To inform healthcare professionals about this clinical sign.
Main Methods:
- Review of clinical observations and literature regarding the Koebner phenomenon in psoriasis.
- Analysis of reported cases linking trauma to psoriatic lesion development.
Main Results:
- The Koebner phenomenon can be triggered by various forms of trauma, including tattoos and insect bites.
- The presence of this phenomenon in patients with suspected psoriasis can be a valuable diagnostic clue.
Conclusions:
- Physicians should consider the Koebner phenomenon as a potential indicator for psoriasis.
- Early identification of this manifestation can facilitate timely diagnosis and management of psoriasis.

01:25Assessment of the Rectum and Anus
636
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.

Introduction
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

01:22Formation of the Platelet Plug
8.0K
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

01:22Esophageal Perforation-I: Introduction
231
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

01:30Peptic Ulcer Disease I: Introduction
401
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
