  • Urticaria - Primary Care Treatment Pathway
    DORSET MEDICINES ADVISORY GROUP Urticaria - Primary Care Treatment Pathway Urticaria – also known as hives or nettle rash – is a raised, itchy rash that can occur on just one part of the body or be spread across large areas. The weals of urticaria last less than 24 hours although patients may develop new weals on a daily basis. If urticaria clears completely within six weeks, it is known as acute urticaria. Urticaria occurring for more than six weeks is referred to as chronic urticaria. Most cases of chronic disease occur without an obvious trigger (chronic spontaneous urticaria). Some urticaria has a physical trigger such as pressure (symptomatic dermographism or delayed pressure urticaria), cold or exercise (cholinergic urticaria), or may be drug induced (e.g. by NSAIDS, ACE inhibitors and opioids). All forms of urticaria can be treated with antihistamine although physical urticaria is less likely to respond to treatment than spontaneous urticaria. Most cases of urticaria settle spontaneously within two years but the condition can last for decades in some patients. Referral criteria Refer routinely to dermatology if patients are not responding to standard treatment (see primary care treatment below, up to step 4), they can then be considered for immunomodulation treatment such as ciclosporin (can be very useful for patients thought to have an autoimmune basis for their urticaria), methotrexate or omalizumab. The diagnosis of urticaria is primarily clinical therefore do not routinely refer for allergy testing. The British Association of Dermatologists (BAD) has produced a patient information leaflet which covers this in detail for patients. PRIOR TO SPECIALIST REFERRAL -conduct a full blood count (FBC), erythrocyte sedimentation rate (ESR), thyroid function tests (TFTs), liver function tests (LFTs), and Helicobacter pylori screening (if gastrointestinal symptoms are present).

  • Clinical Study of Nail Changes in Papulosquamous Disorders
    Original Research Article Clinical study of Nail changes in papulosquamous disorders Vishal Wali1, Trivedi Rahul Prasad2* 1Associate Professor, 2Post Graduate, Department of Dermatology, Venereology and Leprology, Mahadevappa Rampure Medical College, Sedam Road, Kalaburagi (Gulbarga) 585105, Karnataka, INDIA. Email: [email protected] Abstract Background: Nail disorders comprise ~10% of all dermatologic conditions. Nail disorders include those abnormalities that effect any portion of the nail unit. The nail unit includes the plate, matrix, bed, proximal and lateral folds, hyponychium, and some definitions include the underlying distal phalanx. These structures may be effected by heredity, skin disorders, infections, systemic disease, and aging process, internal and external medications, physical and environmental agents, trauma, and tumours, both benign and malignant. The main contributors being papulosquamous disorder. Nail changes in papulosquamous disorder have been inadequately discussed and only limited studies are present. This study aims to throw some light about frequency of nail involvement in papulosquamous disorders and its various patterns. Methodology: This is the descriptive study. It was conducted in department of DVL of Mahadevappa Rampura Medical college and Basaveshwar teaching and general hospital, Kalaburagi from July 2019 to Feb 2021. General, systemic and dermatological examinations were done. Nails were examined in detail. Special investigations like skin biopsy and potassium hydroxide (KOH) mount was done in relevant cases. Results: There were 50 cases of papulosquamous disorder. The most common papulosquamous disorder was psoriasis, followed by lichen planus and PRP. Out of these the most common nail change was pitting (81%) and lest common was dorsal pterygium (%) Conclusion: Nail being an important appendage affecting various dermatosis and acts as window in diagnosis.

Atypical Variants of Mycosis Fungoides REVIEW DOI: 10.4274/jtad.galenos.2021.09719 J Turk Acad Dermatol 2021;15(2):30-33 Atypical Variants of Mycosis Fungoides Dursun Dorukhan Altınışık, Özge Aşkın, Tuğba Kevser Uzunçakmak, Burhan Engin Istanbul University-Cerrahpasa, Cerrahpasa Faculty of Medicine, Department of Dermatology, Istanbul, Turkey ABSTRACT Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma (CTCL) and it is characterised by specific histological features. MF is in a spectrum of disorders which includes Sezary syndrome and other CTCL subtypes. Clinically and histopathologically it can imitate other T-cell mediated dermatosis hence making its diagnosis difficult. Due to different prognosis and difference in treatment strategies other subtypes of CTCL must be differentiated from MF. MF is a clinically indolent low-grade lymphoma which is seen in people aged between 55- 60 and it’s seen more commonly in men (2:1 ratio). Meanwhile other subtypes of MF like folliculotropic variant may show relatively a more aggressive course and our treatment strategy may differ.

  • The Management of Psoriasis in Adults
    DORSET MEDICINES ADVISORY GROUP THE MANAGEMENT OF PSORIASIS IN ADULTS Psoriasis is a common, genetically determined, inflammatory and proliferative disorder of the skin, the most characteristic lesions consisting of chronic, sharply demarcated, dull-red, scaly plaques, particularly on the extensor prominences and in the scalp. Self-care advice Many people's psoriasis symptoms start or become worse because of a certain event, known as a trigger. Common triggers include: • an injury to skin such as a cut, scrape, insect bite or sunburn (this is known as the Koebner response) • drinking excessive amounts of alcohol • smoking • stress • hormonal changes, particularly in women (for example during puberty and the menopause) • certain medicines such as lithium, some antimalarial medicines, anti-inflammatory medicines including ibuprofen, ACE inhibitors (used to treat high blood pressure) and beta blockers (used to treat congestive heart failure) • throat infections - in some people, usually children and young adults, a form of psoriasis called guttate psoriasis (which causes smaller pink patches, often without a lot of scaling) develops after a streptococcal throat infection, although most people who have streptococcal throat infections do not develop psoriasis • other immune disorders, such as HIV, which cause psoriasis to flare up or to appear for the first time Advice for patients can be found here Management pathway For people with any type of psoriasis assess: • disease severity • the impact of disease on physical, psychological and social wellbeing • whether they have psoriatic arthritis • the presence of comorbidities. • Consider using the Dermatology quality of life assessment: www.pcds.org.uk/p/quality-of-life Assess the severity and impact of any type of psoriasis: • at first presentation • before referral for specialist advice and at each referral point in the treatment pathway • to evaluate the efficacy of interventions.

  • 10 Chronic Urticaria As an Autoimmune Disease
    10 Chronic Urticaria as an Autoimmune Disease Michihiro Hide, Malcolm W. Greaves Introduction Urticaria is conventionally classified as acute, intermittent and chronic (Grea- ves 2000a). Acute urticaria which frequently involves an IgE-mediated im- munological mechanism, is common, its causes often recognised by the patient, and will not be considered further. Intermittent urticaria – frequent bouts of unexplained urticaria at intervals of weeks or months – will be dis- cussed here on the same basis as ‘ordinary’ chronic urticaria. The latter is conventionally defined as the occurrence of daily or almost daily whealing for at least six weeks. The etiology of chronic urticaria is usually obscure. The different clinical varieties of chronic urticaria will be briefly considered here, and attention will be devoted to a newly emerged entity – autoimmune chronic urticaria, since establishing this diagnosis has conceptual, prognostic and the- rapeutic implications. Contact urticaria and angioedema without urticaria will not be dealt with in this account. Classification of Chronic Urticaria The clinical subtypes of chronic urticaria are illustrated in the pie-chart of Fig. 1. The frequency of these subtypes is based upon the authors’ experience at the St John’s Institute of Dermatology in UK. Whilst there may well be mi- nor differences, it is likely that the frequency distribution of these subtypes will be essentially similar in most centres in Europe and North America (Grea- ves 1995, 2000b). However, our experience suggests that the incidence of angioedema, especially that complicated by ordinary chronic urticaria is sub- stantially lower in Japan and south Asian countries (unpublished observation). 310 Michihiro Hide and Malcolm W.

It is characterized by follicular hyperkeratotic papules that may coalesce into plaques. Individual lesion shows conical projection, hair like horny spine. The etiology is unknown but genetic predisposition has been suggested as a possible cause. It has a tendency to disappear spontaneously at puberty. Herein we present a 12-year-old boy presented with 6- month- history of persistent asymptomatic skin lesions. Skin examinations revealed multiple grouped scaly, hypopigmented tiny follicular papules with horny spines on his back. Soles showed planter keratoderma. Skin biopsy showed dilated hair follicle filled with keratin plugging. Diagnosis of LS associated with planter keratoderma was made. The patient responded well to topical lactic acid (12%), urea (20-30%), and betamethasone valerate (0.1%) preparations. Keywords Lichen spinulosa, Lichen Spinulosus 1. Introduction appearance. LS usually involves extensor surfaces of arms, trochanteric regions, neck, abdomen, buttocks, thigh, Lichen spinulosus (LS) is a genetic disorder of popliteal fossae, and knees. The histopathology of the lesion is not specific showing dilated hair follicle with keratin keratinization of hair follicles. LS was first described by Adamson in 1908.
