Hence Neonatal Dermatology includes the spectrum of cutaneous manifestations occurring during these first four weeks of life. Skin changes are common in neonates and often cause anxiety and serious concern to the parents. Although most are benign and self-limited some may require further work- up in order to rule out a serious condition . Many factors may influence the pattern of dermatoses in newborns like environmental ,maternal , regional and racial factors .Therefore a thorough understanding of the physiologic characteristics and peculiarities of neonatal skin is important. Neonatal dermatoses can be classified as : 1) Transient benign skin disorders 2) Developmental abnormalities 3) Acquired skin disorders. 4) Iatrogenic and traumatic disorders. There are very few published literature on neonatal dermatoses in our country. 1 REVIEW OF LITERATURE 2 REVIEW OF LITERATURE DEVELOPMENT OF SKIN The skin arises by the juxtaposition of two major embryological elements: the prospective epidermis that originates from a surface area of the early gastrula, and the prospective mesoderm that comes into contact with the inner surface of the epidermis during gastrulation. The mesoderm provides the dermis and is also essential for inducing differentiation of the epidermal structures, such as the hair follicle. The melanocytes are derived from the neural crest. After gastrulation a single-layered neuroectoderm lies on the surface of the embryo. Depending upon the molecular signal it receives this layer will go on to form the nervous system or the skin epithelium . Development of the epidermis starts at the third week of life . Initially a basal layer of cuboidal cells overlying the mesoderm or future dermis is seen. By the fifth week, a secondary layer of squamous, non-keratinizing, cuboidal cells, known as periderm or epitrichium, develops atop the basal layer. This periderm eventually sloughs 3 off to become a component of a waxy substance called vernix caseosa which serves to protect the fetus from bacterial and environmental insults. ANATOMY Vernix caseosa- It is a greasy, yellow-white substance which is found to coat the skin of a newborn and persists for the first several days of postnatal life. Vernix means “ to varnish” and “caseous” means cheesy nature. Vernix consists of water (81%), lipid (9%), and proteins (10%). Cholesterol esters , wax esters, ceramides ,squalene, cholesterol, triglycerides, free fatty acids are the major lipid composition.1 The development of vernix caseosa proceeds in a cephalocaudal manner and is the result of an orderly progression of epithelial maturation.2 At birth, vernix may cover the entire skin surface or only confined to body folds. It may be absent in very low birth weight and premature infants. Hence they lack the protective function of vernix caseosa. The functions of vernix includes formation of an epidermal barrier in utero to facilitate epidermal growth underneath it , minimises friction of fetal parts during delivery, antimicrobial cover against the bacteriologically rich environment of the mother's genital tract3 . 4 It also prevents loss of fluids and electrolytes or TEWL (Trans Epidermal Water Loss). In addition it also has anti-oxidant 4 ,moisteurising 5, temperature regulation and wound healing properties. 6 The colour of the vernix at birth may reflect intra-uterine problems . For example, it appears golden yellow in hemolytic disease of newborn .Human skin consists of three layers: epidermis, dermis, and subcutaneous fat.

  • Neonatal and Infantile Acne
    Neonatal and infantile acne Also known as neonatal acne, neonatal cephalic pustulosis What‘s the differene etween neonatal and infantile ane? Neonatal acne affects babies in the first 3 months of life. About 20% of healthy newborn babies may develop superficial pustules mostly on the face but also on the neck and upper trunk. There are no comedones (whiteheads or blackheads) present. Neonatal acne usually resolves without treatment. Infantile acne is the development of comedones (blackheads and whiteheads) with papules and pustules and occasionally nodules and cysts that may lead to scarring. It may occur in children from a few months of age and may last till 2 years of age. It is more common in boys. What causes infantile acne? Infantile acne is thought to be a result of testosterone temporarily causing an over-activity of the ski’s oil glads. I suseptile hildre this ay stiulate the development of acne. Most children are however otherwise healthy with no hormonal problem. The acne reaction usually subsides within 2 years. What does infantile acne look like? Infantile acne presents with whiteheads, blackheads, red papules and pustules, nodules and sometimes cysts that may lead to long term scarring. It most commonly affects the cheeks, chin and forehead with less frequent involvement of the body. How is infantile acne diagnosed? The diagnosis is made clinically and investigations are not usually required. However, if older children (2 to 6 years) develop acne and other symptoms such as body odour, breast and genital development, then hormonal screening blood tests should be considered. How is infantile acne treated? Treatment is usually with topical agents such as benzoyl peroxide, retinoid cream (adapalene) or antibiotic gel (erythromycin).

    REVIEW Drug-Induced Acneform Eruptions: Definitions and Causes Saira Momin, DO; Aaron Peterson, DO; James Q. Del Rosso, DO Several drugs are capable of producing eruptions that may simulate acne vulgaris, clinically, histologi- cally, or both. These include corticosteroids, epidermal growth factor receptor inhibitors, cyclosporine, anabolic steroids, danazol, anticonvulsants, amineptine, lithium, isotretinoin, antituberculosis drugs, quinidine, azathioprine, infliximab, and testosterone. In some cases, the eruption is clinically and his- tologically similar to acne vulgaris; in other cases, the eruption is clinically suggestive of acne vulgaris without histologic information, and in still others, despite some clinical resemblance, histology is not consistent with acne vulgaris.COS DERM rugs are a relatively common cause of involvement; and clearing of lesions when the drug eruptions that may resemble acne clini- is discontinued.1 cally, histologically,Do or both.Not With acne Copy vulgaris, the primary lesion is com- CORTICOSTEROIDS edonal, secondary to ductal hypercor- It has been well documented that high levels of systemic Dnification, with inflammation leading to formation of corticosteroid exposure may induce or exacerbate acne, papules and pustules.

  • Acne and Acneiform Related Eruptions
    Acne and acneiform related eruptions Objectives : ➢ To know the multiple pathogenetic mechanisms causing acne ➢ To recognize the clinical features of acne. ➢ To differentiate acne from other acneiform eruptions such as rosacea. ➢ To prevent acne scars and treat acne efficiently. ➢ To recognize the clinical features of rosacea, it’s variable types, differential diagnosis and treatment ➢ To recognize the features of perioral dermatitis, differential diagnosis and treatment. ➢ To recognize the features of hidradenitis suppurativa and treatment Done by: Sadeem Alqahtani & Khawla Alammari Revised by: Lina Alshehri. [ Color index : Important | Notes | Extra ] ​ ​ ​ ​ ​ ​ ​ ACNE VULGARIS Definition/prevalence: ● Multifactorial disease of pilosebaceous unit that affects both males and females. ​ ​ ● It is the most common dermatological disease. ● Mostly prevalent between 12-24 yrs. Affects 8% between 25-34, 4% between 35-44. Pathogenesis: 1- Ductal cornification and occlusion (micro-comedo). 2- Increased sebum secretion (Seborrhoea). 3- Ductal colonization with propionibacterium acnes. 4- Rupture of sebaceous gland and inflammation. Specialized terms: ● Microcomedone: Hyperkeratotic plug made of sebum and keratin in follicular canal. ​ ● Closed Comedo (Whitehead): Closed follicular orifice, accumulation of sebum and keratin ​ ​ ​ ​ ● Open Comedo (Blackhead): Opened follicular orifice packed with melanin and oxidized lipids ​ ​ ​ ​ ● We categorize acne (depending on the type of lesion) into: mild, moderate and severe. Comedones are considered mild. Nodules, cysts, pustules (can lead to scarring or hyperpigmentation) are ​ ​ considered moderate to severe. ​ ​ ● Our pathognomonic lesion is comedone, you can NOT diagnose acne without having comedones, if you do not have comedones THIS IS NOT ACNE! Clinical features: Acne lesions are divided into: ● Inflammatory (papules,pustules,nodules,cyst). ● Non inflammatory (open, closed comedones).
