Summary
This review covers the physiology of pruritus and systemic diseases causing itching. It offers guidance on evaluating unexplained itching and managing patient discomfort.
Area of Science:
- Dermatology
- Internal Medicine
- Clinical Physiology
Background:
- Pruritus is a common symptom of skin conditions.
- Severe itching can indicate underlying systemic diseases, even without visible skin issues.
Purpose of the Study:
- To review the physiology of pruritus.
- To discuss systemic diseases associated with pruritus.
- To provide evaluation and management guidelines for unexplained pruritus.
Main Methods:
- Literature review of pruritus physiology.
- Analysis of systemic diseases linked to pruritus.
- Synthesis of current therapeutic strategies.
Main Results:
- Pruritus has complex physiological underpinnings.
- Numerous systemic conditions can manifest as pruritus.
- Effective management requires identifying and treating underlying causes.
Conclusions:
- Understanding pruritus pathophysiology is crucial.
- Systemic causes of pruritus must be considered in diagnosis.
- Multidisciplinary approaches can improve patient outcomes.

01:24Chronic Kidney Disease II: Clinical Manifestations
795
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

398
Nursing management for nephrotic syndrome adapts as the disease progresses, with strategies evolving to address advancing symptoms and complications.Early-Stage Management In the early stages, nursing interventions for nephrotic syndrome resemble those used in managing acute glomerulonephritis, focusing on symptom monitoring, fluid balance, and managing mild to moderate edema.Vital Signs: Regularly monitor blood pressure, pulse, respiratory rate, and temperature to promptly identify...

01:26Nephrotic Syndrome II : Assessment and Medical Management
279
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

01:24Nephrotic Syndrome I : Introduction
748
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

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...

01:16Accessory Structures of the Skin: Hair and Hair Follicles
5.0K
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...
