Skin Diseases and Disorders01:23

Skin Diseases and Disorders

4.5K
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...

Accessory Structures of the Skin: Hair Growth and Types

1.9K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.2K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

1.2K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Psychodynamic Therapy01:29

Psychodynamic Therapy

206
Psychodynamic therapies emphasize the exploration of unconscious processes and early childhood experiences as fundamental contributors to psychological difficulties. These therapies, deeply rooted in Freud's psychoanalytic theory, aim to uncover and resolve unconscious conflicts, granting individuals insights that promote emotional and behavioral healing. Contemporary psychodynamic approaches have evolved, integrating a broader range of influences and methodologies while still valuing the...

Autoimmune Disorders01:29

Autoimmune Disorders

925
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Area of Science:

  • Dermatology
  • Psychiatry
  • Immunology

Background:

  • Alopecia Areata (AA) is an autoimmune dermatological condition.
  • Psychological factors may play a role in the pathophysiology of AA.

Purpose of the Study:

  • Review psychodermatological and psychopathological aspects of AA.
  • Examine the etiopathogenesis and comorbidities of AA.
  • Discuss psychiatric and psychological management strategies for AA patients.

Main Methods:

  • Conducted a literature search on PubMed and Google Scholar (1980-2021).
  • Used keywords: alopecia areata, psychological factors, psychodermatology, psychopathology.
  • Screened reference lists and included books/chapters.

Main Results:

  • High comorbidity rates between AA and mental disorders were reported.
  • Stress and psychological factors are implicated in AA development and exacerbation.
  • Further research is needed on the interplay between immune response, stress, and AA physiology.

Conclusions:

  • AA is a complex, multifactorial disease.
  • Genetic, autoimmune, hormonal, neural, and psychological factors likely interact in AA.
  • Psychopathological aspects require greater clinical consideration.
