If > 1 site then systemic antibiotics Treatment: To relieve symptoms generic 200 mg extra super viagra amex, stop new lesions, prevent complications (e. Resistance to fusidic acid is also growing Resistance is growing to topical agents (e. Mupirocin) Scalded Skin Syndrome Due to staph aureus toxin (may be distant site) Skin peels off with little pressure skin looks abnormal damage from within Commonest in infancy Treatment: flucloxacillin plus burn treatment (including fluid balance) Skin 315 Folliculitis Pyoderma located within the hair follicle Usually caused by S aureus Responds well to topical antibacterial measures Furuncle = A boil A deep inflammatory nodule In skin areas subject to friction and perspiration and containing hair follicles Often drain spontaneously, especially with moist heat If recurrent, then? Treat with topical intranasal mupirocin or systemic rifampicin May progress to a carbuncle: more extensive involving subcutaneous fat. Usually in children, for example from cows, dogs, cats or mice Clinical Description Fungal infections usually itch. Have a raised scaling margin that extends outwards There are several classical presentations: Tinea Cruris: in the groin. If feet involvement as well then systemic treatment, otherwise topical Tinea Capitis: Scalp. To hands by itching, where it presents with a dry, hot rash on one palm, with well defined lesions with a scaling edge Tinea Corpus: on the trunk. The changes occur distally, and move back to the nail fold (compared with psoriasis, which is symmetrical and moves distally from the nail fold) Tinea Incognito: Fungal infection treated with steroids. In young adults, causes hypo- or hyper-pigmented macules with powdery scale, on upper trunk, upper arms and neck. Slightly itchy Differential diagnoses: Vitiligo: but pure white lesion (amelanotic), no scaling Pityriasis alba: Usually children and on the face. When immune response is impaired, superficial infections may invade deeper tissues Management Topical Treatment: imidazole preparations, such as clotrimazole and miconazole. Terbinafine is available as a cream Systemic Treatment: Diagnosis should be confirmed before commencing treatment. Skin 317 Viral Infections Molluscum Contagiosum Viral infection with pox virus Small solid papules with umbilication in middle. Stay fairly localised If you squeeze them then virus released (ie infective) Histology: acanthosis and molluscum bodies Disappear in under 9 12 months. Treat if severe Verrucae (Warts) Papova virus: Papillary lesion + polyoma (lots of them) + vacuolation of cells containing the virus Locations: Verruca vulgaris Verruca plana: flat, eg on face Verruca plantaris: on feet, can be painful Verruca palmaris: on hands, can be painful Condyloma accuminatum: Genital. The empty egg shells, known as nits, are white Life cycle: female lice lay about 7 10 eggs each night, these hatch in 9 days. A louse will live for 40 days Where to find them: around the hairline at the back of the neck, behind the ears, on the crown Treat if you find a live insect or an egg within 1 cm of the scalp (hair grows 1 cm a month, so more than 1 cm from head means theyre dead) Use special shampoo from the chemist. Early childhood infections preferential induction of Th1 type cytokines and prevent atopic sensitisation. Cradle cap in babies whose scalp was clear at birth Red, greasy scale, sharply circumscribed In kids = another presentation of atopic. Differential: Infantile psoriasis In adults = allergy to yeast (Pityrosporum ovale) which arrive with grease gland activation at puberty Differential: Psoriasis. But doesnt often affect the face Discoid, and other forms of eczema Pityriasis rosea (usually on trunk and not on the face) Fungal infection: annular, scaling isnt greasy Contact Dermatitis May be irritant or allergic or both. Eg may have worn rubber gloves for years Once sensitised, further exposure to even minuscule amounts reaction after a day or two. Pompholyx (dyshidrotic eczema) Not related to atopic eczema Vesicles +/- bullae on palms, soles, sides of fingers or toes Erythema or scaling absent. If present then just a vesicular eczema Heals with desquamation Differential: fungal infection Treatment:? Treat according to underlying lesion Disseminated Superficial Actinic Porokeratosis: Caucasian. Border has 2 parallel rows of scale Bowens Disease: See Premalignant Lesions, page 326 Chondrodermatitis: On sun damaged ears, may also be due to pressure. Treatment: excision including cartilage otherwise recurrence Lentigo: Brown macules (look like large freckles). May require excision to differentiate Idiopathic Guttate hypomelanosis: pale spots in the shape and distribution of largish freckles on sun damaged skin Freckle: brown macule. Commoner in redheads Skin Neoplasia Naevi and Melanoma Naevi = hamartoma of the skin. Overgrowth of melanocytes in nests along the junction of the dermis and epidermis. Dont become malignant must have junctional activity to do this Dysplastic melanocytic naevi (Atypical Mole Syndrome): Uncontrolled proliferation without malignancy (> 100 with at least one Dysplastic more or a mole > 0. Depigmented symmetrical halo around the mole, but the mole is normal (cf depigmented melanoma where pigmented lesion is not normal and not central) Pathogenesis:? After that sunscreen mainly protects against squamous and basal cell carcinomas Epidemiology: 1 3% of childhood cancers Females 14/100,000, males 9/100,000. Difference is in the distribution on the legs Spotting them: A: asymmetry B: border irregular e. Usually on face, tan macule that slowly enlarges and develops a geographic shape, multicoloured in time.
