Skin Diseases and Disorders

3.8K
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...

Chronic Pancreatitis I: Introduction

87
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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

445
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Skin Cancer

4.1K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Chronic Pharyngitis01:23

Chronic Pharyngitis

1.9K
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,...

Inflammatory Bowel Disease II: Crohn's Disease

219
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Area of Science:

  • Dermatology
  • Neuroimmunology
  • Pharmacology

Background:

  • Chronic prurigo (CPG) is a neuroinflammatory skin condition defined by persistent itching (>6 weeks), lesions, and scratching.
  • CPG significantly impacts patients' quality of life and mental well-being.
  • Chronic nodular prurigo (CNPG) is the most prevalent subtype of CPG.

Purpose of the Study:

  • To provide an overview of CPG pathophysiology.
  • To review current and emerging therapeutic options for CPG.
  • To highlight recent advancements in CPG treatment.

Main Methods:

  • Review of clinical features and disease burden of CPG.
  • Examination of pathophysiological mechanisms underlying CPG.
  • Analysis of approved and investigational therapies for CPG.

Main Results:

  • Dupilumab is the first EMA and FDA-approved therapy for moderate-to-severe CNPG.
  • Several biologics (nemolizumab, vixarelimab, barzolvolimab), JAK inhibitors (povorcitinib, abrocitinib), and opioid modulators (nalbuphine) are under investigation.
  • Ongoing Phase II and III trials are evaluating these novel agents.

Conclusions:

  • Significant progress has been made in understanding CPG pathophysiology.
  • New targeted therapies are emerging, offering potential for improved CPG management.
  • Dupilumab represents a breakthrough, with further therapeutic options anticipated.
