Guidelines for the Topical Treatment of Psoriasis Vulgaris in the Levant and Iraq Area.

Psoriasis vulgaris is a common chronic, inflammatory, multisystem disorder that affects approximately 1.5% to 3.4% of the population in the Middle East. The disease has an impact on the quality of life in a significant number of affected patients. The majority of patients (approximately 70%) have mild to moderate psoriasis that is manageable with topical agents, which generally show a high efficacy to safety ratio. Topical agents can be used alone when treating patients with limited disease or may be used as adjunctive therapy for patients with more extensive psoriasis undergoing systemic treatment. Treatment should also be customized to meet individual patients' needs. To optimize the topical treatment of psoriasis in the Levant and Iraq area, dermatology experts from Iraq, Jordan, Lebanon, Palestine, and Syria met and initiated a project to develop guidelines and recommendations for the topical management of psoriasis. The guidelines are based on literature evidence and experts' opinions. We present recommendations for the use of topical corticosteroids, vitamin D analogues, calcineurin inhibitors, tazarotene, salicylic acid, anthralin, and coal tar, as well as combination therapy, based on their efficacy and safety profiles.

Herpes gestationis (Pemphigoid gestationis).

Herpes gestationis, coined by Milton in 1872, or gestational pemphigoid is the most clearly characterized dermatosis of pregnancy. It is a rare vesiculo-bullous eruption that develops during the last trimester or even postpartum and creates severe pruritus. Its etiology is unknown, but it is considered as an autoimmune-mediated dermatosis closely related to the pemphigoid group. Herpes gestationis is associated with a positive C3 deposition along the base of the epidermis in salt-split skin, with increased frequency of HLA-DR3 and also the combination DR3 and DR4. It has a high risk of prematurity and disappears in the postpartum period within weeks or months.

Life-threatening environmental dermatoses and agents of mass destruction with serious systemic consequences.

The idea of this paper is to acquire a new view of some environmental conditions affecting the skin and carry with them significant morbidity. It is also to understand their etiology and nature to prevent their hazardous and serious complications which are life-threatening. Although most dermatologic disorders rarely have a fatal outcome, there are many potentially fatal medical disorders that have early or major dermatologic manifestations. Some cases lead to death because of the loss of barrier function of the epidermis with fluid and electrolyte loss or from systemic invasion of microorganisms. In others, dermatologic signs reveal an underlying systemic disease where death may occur from the underlying problem.

Community understanding and prevention of sexually transmitted diseases.

In spite of the various attempts by health care workers to reduce the morbidity and mortality of sexually transmitted diseases (STDs), more than 15 million persons acquire STDs each year in the United States. The situation is more serious in developing countries and, in particular, Africa and Southeast Asia. The causes of the increase in STDs are many, but we believe that alterations in family structures, drug and alcohol addiction, wars and mobilization of armies and movement of populations, in addition to change in sexual behaviors and lax morality are the main ones. Education, counseling, and community understanding of the risks of STDs are very essential factors in prevention and control. Physicians need to recognize the manifestations of STDSs and start the treatment as early as possible, but at the same time, more efforts are needed for prevention.

Necrobiotic xanthogranuloma associated with paraproteinemia and non-Hodgkin's lymphoma developing into chronic lymphocytic leukemia: the first case reported in the literature and review of the literature.

A 56-year-old married female presented in May 1998 with a 5-month history of xanthelasma of the eyelids, followed 4 months later by two enlarged lymph nodes of the left side of the neck and three of the left axilla. At the same time, she developed xanthomatous patches on the face, neck, and shoulders (Fig. 1). The cutaneous lesions were xanthomatous nodules and plaques, affecting the periorbital regions. Later, the whole face was affected, followed by ulcerated lesions on the scalp, chest, back, and extremities (Fig. 2). The skin lesions became painful, pruritic, ulcerated tumors (Fig. 3). In July 1998, computed tomography (CT) scans of the chest and abdomen with contrast medium showed pretracheal, bilateral axillary, right retrochural, paracaval, aortocaval, and para-aortic lymph node enlargement. These findings were suggestive of lymphoma. CT scan also showed slight heterogeneous hypodensity in the upper part of the right lobe of the liver, suggesting fatty infiltration. The spleen, pancreas, and suprarenal glands appeared normal. One cervical and two left axillary lymph nodes were excised. They revealed total replacement of the nodular architecture by a diffuse proliferation of mature lymphoid cells having small nuclei and a crumbled chromatin pattern, and very rare mitosis. It was concluded from the lymph node biopsies that these changes were typical of non-Hodgkin's lymphoma, diffuse and small cell type, of low-grade malignancy. A bone marrow aspirate showed a marrow heavily infiltrated by lymphoid cells with some immaturity. The megakaryopoiesis was adequate. Trephine biopsies showed similar changes. Iron stores appeared to be absent. The bone marrow picture was consistent with diffuse, well-differentiated non-Hodgkin's lymphoma, developing into chronic lymphocytic leukemia (CLL). Endoscopy showed antral-type gastric mucosa exhibiting mild chronic gastritis. Skin biopsy from a fresh lesion on the back showed a diffuse inflammatory cell infiltrate with collections of histiocytic cells. It also showed necrobiotic foci, surrounded by mixed inflammatory cells, dark palisaded foamy histiocytes, and a few Touton giant cells. These findings are compatible with necrobiotic xanthogranuloma (NXG) (Figs 4 and 5). Blood film showed normochromic, normocytic erythrocytes with anisopoikilocytotic leukocytes and normal platelets. The sedimentation rate was 90 mm in the first hour. The blood picture also showed monoclonal IgG paraprotein (3170 mg/dL) of the kappa light chain type. The patient was treated by the oncologist for her lymphoma, and was given Cytoxan, prednisolone, endoxan, Leukeran, and melphalan. She showed an excellent response to pulsed treatment with steroids (60 mg prednisolone orally daily for 5 days, repeated every month for 6 months). She also responded to Leukeran at a dose of 5 mg daily for 5 days every month for 6 months, and showed regression in the size of the lymph nodes. The treatment of her skin lesions was unsatisfactory in spite of the fact that she was given cyclosporine and both systemic and topical corticosteroids.
