This document discusses various types of dermatitis and eczema. It begins with an introduction noting that dermatitis and eczema refer to inflammation of the skin. Eczema progresses through acute, subacute, and chronic stages. Prevalence in the US is 10-12% in children and 0.9% in adults, rising internationally. Atopic eczema is a chronic pruritic inflammation affecting the epidermis and dermis, commonly presenting in infants and children. Contact dermatitis results from allergic or irritant reactions to substances touching the skin. Other conditions discussed include lichen simplex chronicus, discoid eczema, seborrhoeic dermatitis, and
Exfoliative dermatitis is a condition where more than 90% of the skin surface becomes inflamed and scaly. It can be caused by underlying skin diseases like psoriasis or eczema, drug reactions, or systemic illnesses. Clinically, it presents as generalized redness and scaling of the skin with potential complications involving other organs. Making an accurate diagnosis requires considering the patient's medical history and risk factors, examining skin changes and biopsy findings, and ruling out potential etiologies through laboratory tests and imaging.
Atopic dermatitis is a chronic, inflammatory skin disease associated with elevated IgE levels and family history of atopy. 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.
1. Atopic dermatitis is the most common type of dermatitis, which is a chronic, pruritic inflammatory skin disease that varies in severity. It primarily causes intense itching.
2. The pathogenesis is multifactorial involving genetic predisposition, skin barrier dysfunction, and immune abnormalities.
3. Treatment focuses on managing flares with topical corticosteroids and infections, while remission involves long-term emollient use and trigger avoidance.
This document discusses eczema, including its various types and subtypes. It provides information on the epidemiology, pathogenesis, clinical features, investigations, and management of different forms of eczema. Some key points include:
- Eczema is a clinical and histological pattern of inflammation seen in various dermatoses with diverse etiologies. Common symptoms include itching and skin changes like erythema, scaling, and fissuring.
- The prevalence of eczema varies by type. Atopic eczema is most common in children under 11 years old. Nummular dermatitis and asteatotic eczema are more common in older age groups.
- Fact
Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition characterized by dryness, itchiness, redness, and sometimes oozing. It is one of the most common skin disorders in children, affecting up to 30% of preschoolers. The exact causes are unknown but include genetic susceptibility and environmental triggers weakening the skin barrier. Treatment focuses on moisturizing to repair the barrier, identifying and avoiding triggers, and controlling flares with topical corticosteroids or other immunosuppressants. While there is no cure, many children outgrow eczema by adolescence.

This document discusses atopic dermatitis (AD), also known as eczema. It defines AD as an itchy, chronic skin condition often starting in childhood characterized by rashes, redness, itchy bumps and blisters that may become cracked or thickened. The document discusses the etiology and pathogenesis of AD involving skin barrier dysfunction and immune system abnormalities. It describes the clinical features of AD in infants, children and adults and provides diagnostic criteria. Treatment recommendations include moisturizers, bathing, wet wrap therapy, topical corticosteroids and avoiding topical antihistamines.
Atopic dermatitis is a chronic inflammatory skin condition that often starts in early childhood. It is caused by complex interactions between genetic, immune, and environmental risk factors. A defective skin barrier is a consistent feature of atopic dermatitis. Filaggrin gene mutations contribute to impaired skin barrier function. Diagnosis is based on clinical features like itchy skin rashes and personal or family history of atopy. Treatment focuses on managing symptoms and avoiding triggers while working to strengthen the skin barrier.
The document outlines a dermatology syllabus covering various common skin conditions organized into 18 topics. Some of the key conditions discussed include eczema (its classification and types), urticaria, acne/rosacea, psoriasis, infections (bacterial, viral, fungal), sexually transmitted diseases, tumors (benign and malignant), and connective tissue diseases. For each condition, the syllabus provides details on pathogenesis, clinical features, diagnostic criteria where relevant, and treatment approaches.
Eczema herpeticum is a skin infection caused by the herpes simplex virus that commonly causes cold sores. It occurs in people with inflammatory skin conditions like atopic dermatitis. The herpes virus infects large areas of compromised skin. Symptoms include clusters of small, painful blisters that ooze pus and can cause fever. Prompt diagnosis is important as eczema herpeticum can spread widely and become serious without treatment.
Allergic rhinitis is an IgE-mediated inflammation of the nasal mucosa following exposure to an allergen. It affects 10-30% of people globally. Symptoms include sneezing, rhinorrhea, nasal obstruction, and itching. Diagnosis involves demonstrating IgE sensitivity, usually via skin prick testing or allergen-specific IgE blood tests. Treatment includes allergen avoidance, pharmacotherapy like antihistamines and intranasal corticosteroids, and immunotherapy for persistent cases. Immunotherapy aims to induce tolerance through repeated administration of allergen extracts.

This document provides information on skin anatomy, various benign dermatologic conditions, and treatments for skin conditions. It discusses the layers of the epidermis and dermis. It also describes common benign conditions like contact dermatitis, atopic dermatitis, acne, rosacea, psoriasis, nevi, and alopecia. For each condition, it discusses pathogenesis, clinical features, diagnosis, and management approaches including medications, procedures, and lifestyle changes.
This document discusses irritant contact dermatitis (ICD) and its causes, pathogenesis, epidemiology, clinical manifestations, and differences from allergic contact dermatitis. ICD is caused by contact with irritating chemicals, physical agents, or microbes in the environment. It results in skin lesions, mucosa lesions, or semi-mucosa lesions through irritant pathogenic mechanisms. ICD presents with erythema, edema, weeping lesions, vesicles or bullae and the reaction peaks quickly then starts to heal. In contrast, allergic contact dermatitis involves a sensitization phase and elicitation phase and presents with pruritus, vesicles and oozing lesions that spread beyond the contact area.
This document discusses neutrophilic dermatoses, a spectrum of disorders characterized by neutrophilic infiltration of the skin without true vasculitis. Key points include:
- Common features include a neutrophilic vascular reaction, some cases having a reactive or systemic cause, disorders may coexist or occur sequentially in individuals.
- Classification includes disorders grouped by location of neutrophilic infiltrate (epidermal vs dermal).
- Pyoderma gangrenosum is discussed in depth, including its pathogenesis, associated diseases, diagnostic criteria, variants (classic, pustular, bullous etc.), investigations and histopathology. Treatment involves immunosuppressive therapy.

This document provides guidelines for the diagnosis and management of atopic dermatitis in Latin America. It was developed by the committee of atopic dermatitis of the Latin American Society of Allergy Asthma and Immunology. The committee reviewed literature and used the Delphi method to define recommendations. Atopic dermatitis is a common skin disease that often precedes other allergic conditions. Its prevalence is high in Latin America due to environmental factors. The pathophysiology involves skin barrier defects and immune/inflammatory responses. Phenotypes are classified based on immunological markers to guide tailored treatment approaches.
Eczema is a non-contagious skin condition that causes itching, inflammation, and sometimes pain. It has no cure but can be effectively treated. The main types of eczema are contact dermatitis, atopic eczema, seborrheic dermatitis, and napkin dermatitis. Treatment depends on the type and severity of eczema, and involves moisturizers, topical corticosteroids or immunomodulators, oral medications in severe cases, and managing triggers. The goal is to relieve symptoms and prevent complications like infection.

Benign lumps are also reviewed, including common types such as warts, cysts, and neck lumps. Finally, the document discusses skin cancers like melanoma, basal cell carcinoma, and squamous cell carcinoma, noting risk factors
Dr Muhammad Raza's presentation provides information about atopic dermatitis (eczema), including its signs and symptoms, causes, diagnosis, and management. The key points are that it is a chronic skin condition causing red, itchy, cracked skin that is common in children; has genetic and immunological factors; and is typically diagnosed clinically and managed through moisturizers, topical steroids, and other topical or systemic treatments depending on severity. The goal is for participants to understand the basic concepts, diagnosis, management, and appropriate referrals for atopic dermatitis.
Pyoderma and bacterial skin infections can take several forms including impetigo, cellulitis, folliculitis, boils, and carbuncles. Impetigo is a superficial infection caused by Streptococcus or Staphylococcus that presents as crusty lesions that are contagious. Cellulitis is a deep bacterial skin infection commonly caused by Streptococcus or Staphylococcus that presents as swollen, warm, painful skin with red streaks and fever. Staphylococcal scalded skin syndrome causes skin reddening and blistering that gives the skin a burned appearance and is usually not life-threatening in children.
The patient, a 52-year-old male smoker with a history of alcoholic cirrhosis, presented with a widespread pruritic rash involving 70% of his body consistent with erythrodermic psoriasis. As the family physician's roles include making an accurate clinical diagnosis of psoriasis, taking a holistic approach to management, educating patients, and knowing treatment options including when referral is needed, the physician must determine the appropriate management for this severe case of erythrodermic psoriasis.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
2. introduction
• Atopic dermatitis is a chronic inflammatory skin disease associated
with cutaneous hyperactivity to environmental triggers that are
otherwise innocuous to non atopic individuals and is often the first
step in the atopic march that results in asthma and allergic rhinitis.
• The clinical phenotype that characterizes atopic dermatitis is the
product of interactions between susceptibility genes, the
environment, defective skin barrier function, and immunologic
responses.
• An understanding of the relative role of these factors in the
pathogenesis of AD is important and has implications for therapy
5. GENETIC FACTORS
• Twin concordance rate for monozygotic twins is 0.72 and only 0.23
for dizygotic twins. This means environmental factors are implicated
in about a third of the cases.
• Numerous susceptibility loci have been implicated and include 1q21
(locus for gene encoding fillagrin protein)
• Other genes affected apart from FLG gene include IL4, SPINK5,
RANTES,IL18, NOD1, DEFB1 e.t.c
• Similar to genes associated with other diseases like asthma, COPD,
HIV, sepsis, Crohns and sarcoidosis
6. ENVIRONMENTAL FACTORS
• UV exposure from sunlight and vitamin D production in the skin
• Tobacco smoking and environmental pollutants
• Urban and rural dwelling and history of recent travel.
• Breast feeding and delayed weaning
• Obesity and physical exercise
• Family size ,exposure to infective agents ,…..the hygeine hypothesis
7. CLINICAL FEATURES
• Varied and depend on the age of patients, and phase of the disease.
• Presentation include:
Itching
Erythema
Papules and vessicle
Eczematous areas with crusting
Hyper and hypopigmentation
Excoriation and lichenification
Xerosis
Secondary Infections
15. ADULTHOOD
• Similar to that in late childhood.
• Lichenification of the flexure areas may be seen
• Hand Eczema occurs in up to 50% of adult cases and might be
persistent from childhood eczema
• Nipple eczema, perioral dermatitis and prurigo nodule are all
features.

18. INVESTIGATIONS
• Initial Diagnosis is rarely aided by investigations. Relevant
investigation however include:
• Total serum IgE
• Skin prick tests
• Patch test for concomittant ACD
• Bacteriological and Viral skin swabs and culture and sensitivity testing
19. • Histology usually not indicated but show spongiosis, disruption of
desmosomes and formation of microvessicles and(exocytosis) in the
acute phase.
• Chronic form, spongiosis is difficult to appreciate, there is marked
acanthosis, hyperkeratosis,hypergranulosis and minimal
parakeratosis.
20. DIAGNOSIS
• Based on history and examination findings .
• The Hanifin and Rajka major and minor diagnostic criteria is a
comprehensive tool for diagnosis of atopic dermatitis.
• The UK working party diagnostic criteria is a revision of Hanifin Rajka
which is simpler to use and suitable for both epidemilogical studies
and in the clinic setting.
21. Hanifin and Rajkal diagnostic criteria
Major Criteria: Must have three or more of:
• Pruritus
• Typical morphology and distribution
• Flexural lichenification or linearity in adults
• Facial and extensor involvement in infants and children
• Chronic or chronically-relapsing dermatitis
• Personal or family history of atopy (asthma, allergic rhinitis, atopic
dermatitis)
22. Hanifin and Rajkal diagnostic criteria Contd.
• Minor criteria: Should have three or more of the following:
• Xerosis
• Ichthyosis,palmar hyperlinearity or keratosis pilaris
• Immediate type skin test reactivity
• Raised Serum IgE
• Early age of onset
• Tendency towards cutaneous infections (especially S.Aureus and
herpes simplex)
23. Minor criteria contd.
• Tendency toward non specific hand and foot dermatitis
• Nipple eczema
• Cheilitis
• Recurrent conjuctivitis
• Dennie – Morgan infraorbital folds
• Keratoconus
• Anterior subscapular cataracts
• Orbital darkening
24. HANIFIN AND RAJKA DIAGNOSTIC CRITERIA
FOR ATOPIC DERMATITIS CONTD.
Facial pallor or facial erythema
Pityriasis alba
Anterior neck folds
Itch when sweating
Intolerance to wool and lipid solvents
Perifollicular accentuation
Food intolerance
Course influenced by environmental factors
White demographism or delayed blanch
25. U.K. working party’s diagnostic criteria
History of pruritus plus 3 or more of the following:
• Onset under the age of 2 years (not used if child is less than 4yrs)
• History of involvement of skin creases
• History of a generally dry skin in the past year
• Personal history of asthma or hay fever or positive family history in
patients <4yrs.
• Visible flexural dermatitis
26. ASSesing Severity
•Assesing severity of lesion is part of initial
assesment.
•The best scores being used currently are the
EASI and SCORAD scales as they are the most
validated scales. They also show good
validity, reliability and sensitivity.
29. TREATMENT
• Counselling is a very important and initial treatment strategy
• Explaining in simple language the aetiology and clinical
course of the disease
• Basic skin care practices.
• Decrease frequency and duration of baths. The wrinkle
sign signals that bath time is already prolonged
• Identification and avoidance of triggers
30. TREATMENT CONTD.
• First line Treatment:
• Emollients
• Topical corticosteroids (TCS)
• Anti histamines
• Antibiotics, antifungal and antiviral agents when necessary
• Topical calcineurin inhibitors (TCI) for “steroid phobia” or lesions on the face
• Maintenance :TCS and TCI twice weekly and daily emolients
31. Poor response?
• Second line treatment:
• Reassess patient
• Short course topical potent steroids
• Review diet in children and intensify search for triggers and re emphasize
need for avoidance
• Consider admission
• Physical methods like wet wraps and phototherapy (for adults only)
39. Concluding remarks
•A good understanding of the pathogenesis
and disease course of AD by the physician
translates to better education of the patient
and this results in better outcomes.
•Basic skin care practices and TCS will often
suffice
40. •However there are resistant cases, and some
factors may necessitate use of systemic
therapy in some patients.
•New treatments in development hold
tremendous promise in the treatment of AD.

Editor's Notes
. Many bacteria and viruses elicit a TH1-mediated immune response, which down-regulates TH2 responses. The first proposed mechanism of action of the hygiene hypothesis stated that insufficient stimulation of the TH1 arm and stimulating the cell defense of the immune system, leads to an overactive TH2 arm. This in turn stimulates the antibody-mediated arm of the immune system, which lead to allergic diseases63, 64
