Defining Psychology

7.6K
Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...

Defining Social Psychology

387
Social psychology investigates how the presence and actions of others influence individual behavior, cognition, and emotion. Examining the social environment's impact provides a scientific framework for understanding how individuals perceive others and are, in turn, influenced by them. This field seeks to uncover the underlying principles guiding social interactions, exploring phenomena such as conformity, obedience, and prosocial behavior.Core Themes in Social PsychologyOne central focus of...

Polymers: Defining Molecular Weight01:01

Polymers: Defining Molecular Weight

3.8K
Unlike small molecules with definite molecular weights, polymers are a mixture of individual polymer chains of varying lengths, each with a unique molecular weight.  So, the molecular weight of a polymer is expressed as an average value based on the average size of the polymer chains. The two most common forms of averages used for polymers are the number average molecular weight and weight average molecular weight.
The number average molecular weight (Mn) is the summation of the number...

Chronic Pharyngitis01:23

Chronic Pharyngitis

11.5K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Chronic Pancreatitis I: Introduction

688
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Area of Science:

  • Dermatology
  • Clinical Medicine

Background:

  • Chronic prurigo significantly impacts quality of life and treatment is challenging.
  • A lack of clear definition and classification hindered previous understanding and management.
  • A European task force focused on pruritus aimed to address these gaps.

Purpose of the Study:

  • To establish a clear definition and classification system for chronic prurigo.
  • To delineate chronic prurigo as a distinct disease entity.
  • To differentiate chronic prurigo from acute/subacute prurigo and psychogenic lesions.

Main Methods:

  • A European task force specializing in pruritus convened to develop consensus.
  • Clinical and pathophysiological aspects of chronic prurigo were reviewed.
  • Diagnostic criteria, including obligatory and associated features, were established.

Main Results:

  • Chronic prurigo is defined by chronic pruritus, persistent scratching, and pruriginous lesions.
  • Five clinical subtypes were identified: papular, nodular, plaque, umbilicated, and linear.
  • Chronic prurigo is proposed as a distinct disease, separate from acute/subacute forms and psychogenic lesions.

Conclusions:

  • The proposed definition and classification provide a framework for diagnosing and understanding chronic prurigo.
  • Recognizing chronic prurigo as a distinct disease facilitates appropriate management and research.
  • Clear demarcation from other conditions is crucial for accurate diagnosis and treatment strategies.
