Skin disorders are commonly encountered in HIV-infected patients, and they may be the first manifestation of HIV disease. The spectrum of skin disorders depends on:. In general, declining immunity is associated with increased number and severity of skin disorders. The advent of HAART has changed the spectrum of skin disorders by improving host immunity, which in turn reduces the occurrence of Kaposi's sarcoma and some of the skin infections Box HIV-infected patients are more likely than the general population to suffer from adverse drug reactions.
Cutaneous manifestations may vary with one's geographic location. Skin diseases of HIV-infected persons can be systematically classified by their pathogenesis Box The drug history, morphology of primary lesion 4 Box In many cases, HIV-associated skin diseases can be easily recognised on clinical grounds, especially in the early HIV disease where clinical atypia is less frequent.
When diagnostic difficulty is encountered, skin biopsy should be considered for both histologic and microbiological evaluation. As HIV-infected persons frequently have more than one dermatosis, several biopsies may be necessary. Skin diseases are rarely life-threatening, but many of them are life-ruining.
Not only can there be cosmetic disfigurement, the intense pruritus due to eosinophilic folliculitis may severely impair the patients' quality-of-life. Therefore, management of these apparently minor conditions should not be overlooked. However, prolonged high-dose systemic steroid should be used with caution because of the immunosuppressive effects. Although phototherapy can alleviate pruritus or improve psoriasis in HIV-infected patients, its use is hampered by its upregulation of HIV transcription.
Acute seroconversion syndrome is very much like Epstein-Barr virus infection. This eruption distributes over the trunk and sometimes the palms and soles resembling secondary syphilis.
Oral and genital erosions have also been reported. The histology is non-specific. It shows mononuclear cell infiltrates in the upper dermis. Nevertheless, penicilliosis can manifest as ulcers, nodules, maculopapules, acneiform lesions or folliculitis. Wright, Giemsa or PAS stain demonstrates intracellular and extracellular yeast-like organisms that are spherical to elliptical shape.
The basophilic organisms have clear transverse septa. Bacillary angiomatosis is an infectious disease of skin and viscera characterised by angiomatous lesions.
The causative agents are B. It presents as single or multiple red-purple nodules on the eyelids, mucosae, liver or spleen. Histology shows lobular capillary proliferation. Warthin-Starry stain demonstrates clumps of bacilli. It can be effectively eradicated by erythromycin, doxycline or minocycline. Mycobacterial disease is caused primarily by Mycobacterium tuberculosis , M. The altered immunity in HIV disease may result in the absence of characteristic histology, such as caseating granuloma.
An accurate diagnosis relies on the demonstration of acid fast bacilli or positive tissue culture. The skin lesions of these mycobacterium species may take the form of nodules, plaques, papulonecrotic lesion, pustules, abscess or erythema nodosum.
In practice, skin lesions of mycobacterial infection are rare even in the commonly encountered M. It usually represents the reactivation of latent virus. The usual manifestations are orolabial vesicles, anogenital disease or herpetic whitlow. However, facial lesions manifested as folliculitis has been reported. Treatment response to acyclovir is often less marked than the immunocompetent individual.
Some clinicians prefer the use of valacyclovir or famciclovir because of improved pharmacokinetics and convenience of administration. For acyclovir-resistant HSV, intravenous foscarnet or cidofovir can be used. Varicella zoster virus infection can occur at any stage of HIV disease. HIV infected children who develop chickenpox are more likely to suffer from complications such as pneumonia than non-HIV infected individuals.
Herpes zoster is common in the early stage of HIV infection and may be the first clue of HIV infection in a young healthy adult. However, multidermatomal lesions are more frequent in advanced HIV disease. Atypical features such as necrotic punched-out ulcers or hyperkeratotic ulcerated nodules have been reported.
It is caused by pox virus that selectively infects human epidermal cells. Lesions are usually multiple and have a predilection for the face and genitalia. Although the typical lesions are pearly papules with central umbilication, atypical lesions such as giant mollusca have been reported in advanced HIV disease.
Molluscum contagiosum in HIV-infected patients is unlikely to resolve spontaneously and is notoriously difficult to treat. Treatment options include cryotherapy, curettage, excision and topical tretinoin.
HAART makes the existing lesions more responsive to the above treatment. Both verruca vulgaris and condylomata acuminata are common in HIV disease. There is an increased incidence of facial and intraoral warts. In the anogenital area, condylomata acuminata may form large vegetating masses or may extend into the anal canal where squamous cell carcinoma may develop.
Recent study suggests routine anal cytology to all HIV-infected men especially in those with low CD4. This can be achieved by podophyllotoxin, imiquimod, CO 2 laser, curettage or surgical removal. Although topical cidofovir gel is not commercially available, its efficacy on the treatment of recalcitrant condylomata acuminata has been reported. The most common presentation is oral or perianal ulcer. Nonetheless, papulovesicular eruptions, purpura, nodules and verrucous lesions have been reported.
The presence of CMV in the skin lesions does not necessarily indicate its pathogenic role. These infectious agents alone could induce the aetiologic process. Furthermore, CMV has occurred in apparently healthy skin. Dauden et al believed that CMV does not play significant pathogenic role in most cases.
Mucocutaneous candidiasis, usually caused by C. It manifests as oral thrush, angular cheilitis, intertrigo, balanitis, paronychia, balanitis and vaginal thrush. Diagnosis is usually based on clinical ground. The presence of psuedohyphae in KOH preparation or wet mount confirms the diagnosis. Topical antifungal agent is usually adequate. Tinea infections and onychomycosis are common in HIV disease. The features are generally similar to the non-HIV infected individual.
Cutaneous fungal infections can mimic inflammatory dermatosis such as seborrhoeic dermatitis or psoriasis, but the asymmetry of lesion suggests a fungal aetiology. Tinea unguium frequently associates with tinea pedis and produces sub-ungual hyperkeratosis, onycholysis and nail discoloration. Topical therapy is usually not effective. Terbinafine is highly efficacious for dermatophytic infection, but not predictably effective for nondermatophytic fungal infection.
Itraconazole is fungistatic against dermatophytes, nondermatophyte mold and yeasts. Effective schedules include "pulse dosing" at mg daily for 1 week per month or continuous dose of mg daily, both of which require 2 months of treatment for fingernails and 3 months for toenails. Many cases have been labeled as "pruritic papular eruption" which is not a specific disease entity. It encompasses many forms of HIV-associated pruritus.
Algorithm 21 A illustrates one of the clinical approaches to HIV-associated pruritus. Eosinophilic folliculitis is the most common pruritic follicular eruption that mainly affects adult HIV-infected men having sex with men. Nevertheless, it has also been reported in male injection drug users and women. This condition is characterised by erythematous papulopustules that predisposes to the trunk with occasional involvement on the face and neck. As chronic intense pruritus is the rule, patients often present with heavily excoriated lesion or secondary prurigo nodularis.
Histologic examination shows a mixed inflammatory infiltrate with a predominance of eosinophils and lymphocytes surrounding and invading the follicular and sebaceous epithelia, resulting in destruction of sebaceous gland.
Treatment of patients with EF is challenging. Various treatments have been tried. These included oral antihistamines, antimicrobials metronidazole, itraconazole and permethrin , isotretinoin and phototherapy. Clinical responses are variable and relapses are common once the treatment is discontinued. Potent topical steroid have also been tried with some success, but are associated with skin atrophy on facial lesions and hypopigmentation in dark phototype individual.
Recently, 0. However, it takes months to clear the folliculitis and requires a satisfactory control of HIV viraemia in order to maintain the remission. Dermatologic manifestations in HIV disease. HIV Manual , pp Skin disease: clinical indicator of immune status in human immunodeficiency virus HIV infection. Int J Dermatol ; Volume 1.
Skin diseases are a common reason for consulting a GP. We aimed to explore different diagnostic approaches of GPs in patients presenting with a dermatological problem. In addition, we aimed to identify strategies used by GPs to handle diagnostic uncertainty in these patients. We conducted interviews 20—40 minutes with 14 GPs using a semi-structured guideline. Recalling encounters with patients with skin disease, GPs described their individual diagnostic strategies. Interviews were taped and transcribed verbatim. Qualitative analysis was conducted by two independent raters using a deductive—inductive approach.

Guidebook to Dermatologic Diagnosis by Susan Burgin pdf. Summary: Publisher's Note: Products purchased from Third Party sellers are not guaranteed by the publisher for quality, authenticity, or access to any online entitlements included with the product. A unique, highly visual and systematic approach to dermatologic diagnosis Guidebook to Dermatologic Diagnosis provides an innovative and methodical approach to the diagnosis of skin lesions and rashes. The mainstay of diagnosis in dermatology is the physical exam which rests on visual diagnosis. This resource classifies dermatoses on morphologic grounds with diseases that look the same grouped together. Centered around "The Wheel of Diagnosis" which factors in several important clinical considerations necessary to formulate an accurate diagnosis, the book is enhanced by numerous images organized by clinical appearance rather than known diagnosis.
This book summarises the key clinical features and their treatment across a range of skin diseases and describes the decision-making process when referring patients to specialists. It describes how treatment of the skin is often very different to other specialities, as both topical and systemic medications are used, and reviews the clinical signs, investigation and diagnostic approaches to skin diseases. Treatment of Skin Diseases: A Practical Guide principally aids primary care physicians, trainee dermatologists and dermatology nurse practitioners, but it is also a convenient management guide for allied health professionals, students and hospital-based physicians. A concise atlas of diagnostic photographs is included and incorporated with a simple set of common differentials to provide a useful reference for primary care readers and those training in dermatology. The book also contains information on the management of common skin problems, together providing a comprehensive introduction to the treatment of skin diseases. The treatment options for secondary and tertiary care are also included to provide a thorough picture of the spectrum of dermatologic therapeutics. Here she also taught dermatology to the medical and postgraduate students, which she continued in UK, where she arrived about a decade ago.
Skin disorders vary greatly in symptoms and severity. They can be temporary or permanent, and may be painless or painful. Some have situational causes, while others may be genetic. Some skin conditions are minor, and others can be life-threatening.

Тогда бы время, необходимое для дешифровки, составило двадцать лет. Производственное управление АНБ под руководством заместителя оперативного директора коммандера Тревора Дж. Стратмора торжествовало победу. ТРАНСТЕКСТ себя оправдал. В интересах сохранения в тайне этого успеха коммандер Стратмор немедленно организовал утечку информации о том, что проект завершился полным провалом.
В шесть тридцать в то утро он позвонил Дэвиду Беккеру. ГЛАВА 97 Фонтейн стремительно вбежал в комнату для заседаний. Бринкерхофф и Мидж последовали за. - Смотрите! - сдавленным голосом сказала Мидж, махнув рукой в сторону окна. Фонтейн посмотрел на вспышки огней в куполе шифровалки.
Он готов был спорить на что угодно, хоть на собственную жизнь, потому что ясно представлял себе весь сценарий. Этот звонок будет для Хейла полной неожиданностью. Он запаникует и в конце концов, столкнувшись с группой вооруженных людей, ничего не сможет поделать.
Миллиард долларов. Соблазнительный образ Кармен тут же улетучился. Код ценой в один миллиард долларов. Некоторое время он сидел словно парализованный, затем в панике выбежал в коридор. - Мидж.
Тот же, кто перехватывал такое сообщение, видел на экране лишь маловразумительную абракадабру. Расшифровать сообщение можно было лишь введя специальный ключ - секретный набор знаков, действующий как ПИН-код в банкомате. Ключ, как правило, был довольно длинным и сложным и содержал всю необходимую информацию об алгоритме кодирования, задействуя математические операции, необходимые для воссоздания исходного текста. Теперь пользователь мог посылать конфиденциальные сообщения: ведь если даже его послание перехватывалось, расшифровать его могли лишь те, кто знал ключ-пароль.
Честно говоря, - нахмурился Стратмор, - я вообще не собирался этого делать. Мне не хотелось никого в это впутывать. Я сам попытался отправить твой маячок, но ты использовала для него один из новейших гибридных языков, и мне не удалось привести его в действие. Он посылал какую-то тарабарщину.
