Atopic dermatitis (AD) is a common chronic inflammatory skin disease characterized by intense itching, dry skin, inflammation, and exudation. It often has an early age of onset, with 50% of cases diagnosed by 1 year of age. AD is frequently associated with asthma, food allergy, allergic rhinitis, and recurrent skin infections. Trigger factors include stress, irritants, microbes, and allergens. The clinical features of AD vary depending on the age of the patient, from erythematous papules and exudation in infants to lichenified plaques on elbows and knees in children and adults. Diagnosis is based on criteria developed by Hanifin and Raj

It defines contact dermatitis as occurring after direct or indirect contact with substances that harm the skin, with irritant and allergic contact dermatitis being most common. Patch testing is described as the gold standard diagnostic test to identify sensitizing allergens. Treatment involves topical corticosteroids with systemic steroids for more severe cases, along with identifying and avoiding triggering allergens through avoidance measures.Atopic dermatitis Position Paper - Latin American Society of Allergy, Asthma ...
Atopic dermatitis Position Paper - Latin American Society of Allergy, Asthma ...Juan Carlos Ivancevich
This document provides guidelines for the diagnosis and management of atopic dermatitis (AD) in Latin America. It summarizes the epidemiology, pathophysiology, risk factors, phenotypes, diagnostic criteria and severity scales for AD. Some key points include: AD prevalence is high in Latin America and increasing due to urbanization and lifestyle changes. Multiple genetic and environmental factors are involved in its pathogenesis. Sensitization patterns differ from other regions, with early and high sensitization rates to mites and other allergens common in Latin America. Phenotypes are described based on Th1, Th2 and autoimmune responses. Diagnosis is based on clinical features and severity can be assessed using scales like SCORAD. Laboratory tests for totalNaturales
Infectious diseases are caused by pathogens like bacteria, viruses, fungi and protists. Some harmful bacteria cause diseases such as tetanus, salmonellosis, conjunctivitis, pneumonia and tonsillitis. Viruses also cause diseases in humans, including measles, chickenpox, the flu, mumps, common colds, papilloma and AIDS. Infectious diseases are caused by microorganisms that can spread from person to person.

Atopic Dermatitis
This document discusses atopic dermatitis (AD), also known as eczema. Some key points:
1. AD is a chronic, relapsing inflammatory skin disease that is most common in childhood. It affects 15-20% of children in industrialized nations.
2. Symptoms vary by age but commonly include itchy, red, scaly skin rashes. Lesions typically affect the face, neck, hands and skin folds.
3. AD results from a complex interaction between genetic and environmental factors. Triggers include wool, harsh soaps and emotional stress. Treatment focuses on reducing triggers and includes emollients, topical steroids and antihistamines.
What 2012 atopic dermatitis
This study examined the relationship between low levels of food and inhalant allergen-specific IgE sensitization early in life and the development of allergic diseases. The study found that low levels of IgE sensitization to egg and milk at 6 months of age were associated with continued IgE sensitization to allergens at age 2 and 5 years. Additionally, low IgE levels at 12 months of age significantly increased the risk of developing eczema by age 2 years. The study suggests that even low levels of early-life IgE sensitization may be clinically relevant and related to the development of allergic disease.

New: Medicine 5th year, 7th lecture/part one (Dr. Sabir)
Iron-deficiency anemia is caused by blood loss, increased demands, or decreased absorption of iron. It affects over 1/4 of the world's population. Symptoms include fatigue, pallor, and spoon-shaped nails. Laboratory tests show microcytic, hypochromic anemia and low iron levels. Treatment involves oral or parenteral iron supplementation to correct the anemia and restore iron stores.
Athopic dermatitis 2
Atopic dermatitis is a genetic disease that causes itchy, red, warm, and tender skin. It often appears before a baby's first birthday and affects the integumentary system. Around 90% of cases develop before age 5. While the exact causes are still being studied, it is not contagious. Symptoms in babies include dry, scaly patches on the skin. In children, a rash often begins in elbow and knee creases and other areas. Adults rarely get it, but it can appear on the neck, face, eyes, and cause very dry, scaly, itchy skin and infections. The main treatment is corticosteroid medicines, which are effective but have side
Eczema by sanaullah
Atopic dermatitis is a chronic, highly pruritic skin disease that is common in childhood. It involves the cheeks, hands, feet and flexural areas. Seborrheic dermatitis affects sebaceous areas in adults and commonly presents as flaky, greasy scales on the scalp. Eczema has endogenous and exogenous forms. Endogenous eczema includes atopic dermatitis while exogenous eczema includes irritant and allergic contact dermatitis caused by external triggers. Proper treatment of eczema focuses on moisturization, reducing irritation and treating secondary infections.
Atopic dermatitis: mechanism of disease
This document summarizes the mechanisms of atopic dermatitis (AD). It discusses the epidemiology of AD and notes that it commonly affects children under 5 years old. The pathophysiology involves genetic, environmental, immunological, and epidermal factors. Key aspects of the pathophysiology discussed include the role of skin barrier dysfunction and genes involved in barrier function like filaggrin. It also examines the role of the immune system in AD, focusing on the predominance of TH2 cytokines and immune cells like dendritic cells, T lymphocytes, mast cells, and eosinophils that perpetuate the inflammatory response in AD.
Eczema
Eczema is a chronic inflammatory skin condition characterized by dry, itchy, scaly, and sometimes infected skin. The underlying cause is a defective skin barrier that allows too much moisture to escape, resulting in dryness. Proper treatment involves frequent use of emollients to restore the skin barrier, along with intermittent use of topical corticosteroids when flare-ups occur. Patient education is important to ensure correct application of treatments and avoidance of exacerbating factors.
Osteoporosis
Osteoporosis poses a significant disease burden, with over 2 million fractures occurring annually in the United States due to low bone density or previous fractures. Bisphosphonates are the mainstay treatment for osteoporosis, approved in the 1990s, but there is ongoing research into their potential links to rare adverse events like osteonecrosis of the jaw or atypical femoral fractures. While more data is still needed, the overall benefits of bisphosphonates in reducing fracture risk are considered to outweigh the potential risks for most osteoporosis patients. Treatment duration should be individualized based on fracture history and risk level.

Atopic dermatitis is a chronic, pruritic inflammatory skin condition seen in individuals with a personal or family history of atopy. It is characterized by periods of flare-ups and remission influenced by environmental and emotional factors. The diagnosis is based on clinical features including pruritus, typical morphology and distribution of lesions, and a history of atopy. Management involves identifying triggering factors, using topical emollients and corticosteroids, oral antihistamines and antibiotics, and more intensive therapies for severe cases such as phototherapy or immunosuppressants.
Atopic dermatitis1
The document discusses atopic dermatitis (AD), also known as eczema. It defines AD as a pruritic, chronic inflammatory skin condition characterized by dry skin and itchy rashes. AD is common in childhood and often runs in families with other allergic diseases. The pathogenesis involves genetic predisposition, skin barrier defects, and abnormal immune responses. Clinical manifestations vary depending on the stage of life, from facial rashes in infants to thickened plaques on flexural areas in older patients. Treatment focuses on moisturizing the skin, identifying trigger factors, and using topical corticosteroids or calcineurin inhibitors to control symptoms.

It is caused by both genetic and environmental factors that impair the skin barrier and lead to immune dysregulation. Key characteristics include intensely pruritic rashes in skin folds and extensor surfaces. Diagnosis is based on pruritus, characteristic rash patterns and locations, chronic relapsing course, and family history of atopy. Impaired skin barrier function, immune abnormalities involving Th2 cells and cytokines, and interactions between nerves, keratinocytes and immune cells all contribute to pathogenesis.

This document provides information on atopic dermatitis (AD), including its definition, epidemiology, pathogenesis, clinical features, complications, diagnosis, and differential diagnosis. AD is defined as an itchy, chronic inflammatory skin condition with a flexural distribution and early age of onset. Genetic and environmental factors contribute to skin barrier dysfunction and immune dysregulation underlying AD. Clinical features vary by age but commonly include dry skin, rashes, and skin thickening/lichenification due to scratching. Secondary infections can occur. Diagnosis is based on characteristic features and history. Differential diagnoses include other eczemas and psoriasis.
Eczema .pptx
Eczema and dermatitis are inflammatory skin conditions characterized by itching, redness, and scaling. The document discusses various types of eczema including atopic dermatitis, contact dermatitis, and essential dermatitis. Atopic dermatitis is associated with family history of atopy and shows involvement of flexural areas. Contact dermatitis can be irritant or allergic in etiology and affects areas of contact. Essential dermatitis is a diagnosis of exclusion with no identifiable cause beyond self-perpetuating itching and scratching.
Atopic dermatitis
Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by dry, itchy skin rashes. It typically begins in childhood and can be associated with other allergic diseases. The prevalence of AD is increasing and is highest in early infancy and childhood. AD results from an allergic reaction causing inflammation of the skin. Genetic factors such as mutations in filaggrin that impact the skin barrier also contribute to AD development. Managing AD involves lifestyle changes, moisturizing skin care, and medications to reduce inflammation and itching.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
