Adverse drug reactions are a major problem in drug therapy, and cutaneous drug reactions account for a large proportion of all adverse drug reactions. Cutaneous drug reactions are also a challenging diagnostic problem since they can mimic a large variety of skin diseases, including viral exanthema, collagen vascular disease, neoplasia, bacterial infection, psoriasis, and autoimmune blistering disease, among others. Furthermore, determining that a particular medication caused an eruption is often difficult when the patient is taking multiple drugs. In this review, we will describe and illustrate a thoughtful, comprehensive, and clinical approach to the diagnosis and management of adverse cutaneous drug reactions. A morphologic approach to drug eruption includes those that are classified as maculopapular, urticarial, blistering or pustular with or without systemic manifestations. Exanthematous drug eruptions, drug hypersensitivity syndrome, urticaria and angioedema, serum sickness-like reactions, fixed drug eruptions, drug-induced autoimmune blistering diseases, Stevens-Johnson syndrome, toxic epidermal necrolysis, drug-induced acne, acute generalized exanthematous pustulosis, lichenoid drug eruptions and photosensitivity eruptions will be discussed.

This study was undertaken to determine the pattern of dermatoses in children in south India. All children <14 years presenting to us between May 2001 and June 2002 were recruited. A total of 2100 children (males -995; females- 1105) with 2144 dermatoses were recorded. Infections and infestations were the most common dermatoses (54.5%) followed by dermatitis and eczema (8.6%), pigmentary disorders (5.7%), insect bite reaction (5.27%), hair and nail disorders (5.2%), miliaria (4.1%), nutritional deficiency disorders (2.8%), urticaria (2.5%), genetic disorders (2.1%), psoriasis (1.4%), collagen vascular disorders (0.5%), hemangiomas (0.5%), drug eruptions (0.3%), pityriasis rosea (0.2%) and others (5.8%). Pyodermas were the most common dermatoses (47.13%) followed by scabies (30.6%) amongst infections and infestations. Atopic dermatitis was noticed only in 3 patients. Insect bite reactions (papular urticaria) (5.27%) and miliaria (4.1%) were attributed to the tropical weather conditions in this coastal area. Genetic disorders including ichthyosis and palmoplantar keratoderma contributed to 2.1% of cases and could be due to the high incidence of consanguinous marriages in this society.

A 20-year-old woman was referred for evaluation after about 2 years of recurrent episodes of localized urticaria during handling of several kinds of raw fish in a sushi shop, where she had worked part-time for 2 years. She had also experienced allergic symptoms such as itching and swelling of her lips, generalized urticaria, laryngeal tightness, stridor and dyspnea immediately after ingestion of raw and cooked seafood, including sole, horse mackerel, sea eel and shellfish, over the previous 1 year before referral. Skin prick tests and blood test for specific IgE antibodies were positive for many kinds of seafood, including sole, horse mackerel, sea eel, eel, crab, and abalone, which belonged to different taxonomic phyla, including Chordata, Arthropoda, and Mollusca. A challenge with a piece of broiled sole induced swelling of the lips, obstruction of the larynx, difficulty with deglutition, and abdominal pain. In addition, serum-specific IgE antibodies to two major fish allergens, parvalbumin and collagen, were detected by ELISA, suggesting that allergic symptoms could be induced by many kinds of seafood in the present patient. She was therefore diagnosed with occupational contact urticaria and oral allergy syndrome due to seafood. At the time of this report, the present patient had been followed for one year and no reactions have occurred since she started to avoid the causative types of seafood.

The purpose of our study was to assess the prevalence and clinical course of patients with chronic idiopathic urticaria (CIU), as well as possible causes or associated findings, laboratory findings and the duration of the disease in patients with chronic urticaria (CU). We retrospectively reviewed the 450 case record forms of patients with CU and/or angioedema who attended the Department of Dermatology, Siriraj Hospital, during the period 2000-2004. Of 450 patients with CU, 337 patients (75%) were diagnosed as CIU. Forty-three patients (9.5%) had physical urticaria, while 17 patients (3.8%) had infectious causes. Other possible causes were food, thyroid diseases, atopy, drugs, dyspepsia and collagen vascular diseases. In eighty-nine percent of patients, no abnormalities were detected at the time of physical examination. The most common abnormal laboratory finding was minimal elevation of the erythrocyte sedimentary rate (42%). In 61 patients, autologous serum skin tests had been done. Fifteen patients (24.5%) had positive results i.e. autoimmune urticaria. Anti-thyroglobulin and anti-microsomal antibodies were positive in 16 % and 12% of CIU patients respectively. After 1 year from the onset of the symptoms, 34.5% of CIU patients were free of symptoms and after 1.2 years from the onset of the symptoms, 56.5% of autoimmune urticaria patients were free of symptoms. The median disease duration of CIU and autoimmune urticaria were 390 days and 450 days respectively. Our study provided an overview of CU and CIU in a large series of Thai patients, based on etiological aspects and clinical courses.

Glucocorticoids (GCs) are among the most commonly used drugs. They have been employed to treat almost every known disease, from urticaria to leukemia. GCs are so termed because of their action to increase plasma glucose as a result of enhanced hepatic gluconeogenesis, but they play, also, key regulatory roles in a wide variety of physiologic processes. They are essential for survival under stress. GC effect is mediated through receptors localised in cytosol. Receptor-GC complexes bind to hormone response elements in nuclear DNA, affect transcription of genes, either stimulating or inhibiting mRNAs. Proteins so produced (enzymes, hormones) are responsible for the steroid response. There is one type of GC receptor and all GCs will affect all tissues in the same way. At present rational use of GCs falls into two categories: replacement therapy (in Addison's diseasse and in congenital adrenal hyperplasia) and pharmacotherapy, mostly for their anti-inflammatory and immunosuppressive properties, but also to lyse leukemic lymphocytes or to reduce brain edema. GC therapy does not cure the primary disease--it only ameliorates its manifestations and provides time for the body natural defenses to work. After the withdrawal of steroid therapy manifestations of primary process usually return. So, as a result, there is no positive effect on long-term prognosis. Most common indications for prologned high-dose GC therapy are in organ transplantation, tumour chemotherapy, collagen vascular syndromes, ulcerative colitis, nephrotic syndrome and regional enteritis. Asthma, allergic diseases, inflammatory eye diseases and blood dyscrasias are also often treated with GCs. Used in pharmacological doses GCs have a number of adverse side effects. The use of alternate 0 day therapy can decrease most GC side effects (less suppression of hypothalamic-pituitary-adrenal axis, growth inhibition, cushingoid features, infections and myopathy). Discontinuation of long-term therapy is potentially difficult ("steroid withdrawal syndrome"). It is necessary to reduce the total dose gradually, in small weekly decrements. Recent use of GCs in prenatal treatment of congenital adrenal hyperplasia is described.

We conducted the current study to define within the spectrum of the neutrophilic dermatoses a group of patients with an urticarial rash clinically and a neutrophilic dermatosis histopathologically. We reviewed the literature on neutrophilic urticaria and we report here a series of patients with this unique presentation. We reviewed all cutaneous biopsies submitted to our department between 2000 and 2006 in which histopathologic evaluation was compatible with this entity. We then retrieved the patient medical records and obtained information about follow-up and associated diseases. This allowed us to identify 9 patients with an urticarial eruption that was characterized histopathologically by a perivascular and interstitial neutrophilic infiltrate with intense leukocytoclasia but without vasculitis and without dermal edema. Four patients also had small foci of necrobiotic collagen bundles. The eruption consisted of pale, flat or only slightly raised, nonpruritic macules, papules, or plaques. Elementary lesions resolved within 24 hours. Purpura, angioedema, and facial swelling were not seen, but dermographism was present in 1 patient. Six patients had fever, 7 had polyarthritis, and 6 had leukocytosis. Seven patients had associated systemic diseases: adult-onset Still disease (3 patients), systemic lupus erythematosus (3 patients), and Schnitzler syndrome (1 patient).A similar rash has been reported previously in the literature, mostly in patients with systemic inflammatory diseases, but the majority of patients reported under the undefined designation of "neutrophilic urticaria" did have a different clinicopathologic presentation. Thus, we suggest naming this eruption "neutrophilic urticarial dermatosis," to emphasize that this entity expands the broad group of cutaneous manifestations of neutrophilic aseptic disease. This entity bears important medical significance as it is strongly indicative of an associated systemic disease, mainly Schnitzler syndrome, adult-onset Still disease, lupus erythematosus, and the hereditary autoinflammatory fever syndromes.

To clarify the prevalence of skin disorders among dermatology patients in Japan, a nationwide, cross-sectional, seasonal, multicenter study was conducted in 69 university hospitals, 45 district-based pivotal hospitals, and 56 private clinics (170 clinics in total). In each clinic, information was collected on the diagnosis, age, and gender of all outpatients and inpatients who visited the clinic on any one day of the second week in each of May, August, and November 2007 and February 2008. Among 67,448 cases, the top twenty skin disorders were, in descending order of incidence, miscellaneous eczema, atopic dermatitis, tinea pedis, urticaria/angioedema, tinea unguium, viral warts, psoriasis, contact dermatitis, acne, seborrheic dermatitis, hand eczema, miscellaneous benign skin tumors, alopecia areata, herpes zoster/postherpetic neuralgia, skin ulcers (nondiabetic), prurigo, epidermal cysts, vitiligo vulgaris, seborrheic keratosis, and drug eruption/toxicoderma. Atopic dermatitis, impetigo, molluscum, warts, acne, and miscellaneous eczema shared their top-ranking position in the pediatric population, whereas the most common disorders among the geriatric population were tinea pedis, tinea unguium, psoriasis, seborrheic dermatitis, and miscellaneous eczema. For some disorders, such as atopic dermatitis, contact dermatitis, urticaria/angioedema, prurigo, insect bites, and tinea pedis, the number of patients correlated with the average high and low monthly temperatures. Males showed a greater susceptibility to some diseases (psoriasis, erythroderma, diabetic dermatoses, inter alia), whereas females were more susceptible to others (erythema nodosum, collagen diseases, livedo reticularis/racemosa, hand eczema, inter alia). In conclusion, this hospital-based study highlights the present situation regarding dermatological patients in the early 21st century in Japan.

Urticarial vasculitis is characterised by inflamed itching or burning red patches or wheals that resemble urticaria but persist for greater than 24 hours. It is often idiopathic but is sometimes associated with collagen-vascular disease, particularly systemic lupus erythematosus. Treatment options include oral antihistamines, oral corticosteroids, dapsone, colchicine or hydroxychloroquine. We describe a male patient with urticarial vasculitis who was treated with omalizumab (anti-IgE) with convincing results and provide a review of previous reports of patients with urticarial vasculitis treated with omalizumab.

Episodic angio-oedema with eosinophilia (EAE) or Gleich's syndrome is a rare condition characterised by recurrent episodes of oedema and eosinophilia, accompanied by urticaria, fever and weight gain. The presence of ascites has not been reported so far. We report a 21-year-old Caucasian woman who presented with marked ocular oedema and ascites. Laboratory evaluation revealed marked eosinophilia. During the last 3 months, three episodes of facial and neck oedema were reported, which resolved spontaneously over a period of 3-5 days. The diagnosis of EAE was established after exclusion of secondary causes (infections, allergic reactions, collagen diseases, neoplasms) and clonal disorders associated with marked eosinophilia. Low-dose steroids resulted in eosinophil decrease and complete resolution of symptoms, including ascites. This case highlights that ascites can be a very rare manifestation of EAE particularly if other more frequent causes of ascites have been excluded and the clinical and laboratory findings are supportive of EAE.

A 35-year-old female, professional diver, reported nausea, vomiting, and systemic hives 20 to 30 minutes after ingestion of antipasto made with jellyfish. Patient reported prior episodes of swelling after stings from several different creatures, including jelly fish. She also developed a systemic allergic reaction after sting from an unknown creature while diving. On the initial visit to our hospital, serum total IgE level was 545IU/ml. We extracted crude allergen from jellyfish and evaluated allergen specific IgE antibody levels using ELISA. Patient samples showed higher levels of jellyfish-derived allergen specific IgE than healthy control samples. Basophils were isolated from the peripheral blood of patient. Stimulation with jellyfish-derived allergen showed expression of surface antigens on basophils increased in a concentration-dependent manner. Methods using sodium dodecyl sulfate poly acrylamide gel electrophoresis and immunoblotting showed acid-soluble collagen fraction from jellyfish contained above 250kDa weighed protein that may have caused this current event. A provocation test using jellyfish samples was not performed due to risk of anaphylactic shock. The patient was diagnosed with a jellyfish allergy due to IgE mediated anaphylaxis after ingestion. She was asked to refrain from consuming any food containing jellyfish. IgE-mediated food allergy caused by jellyfish is rare worldwide. Collagen was speculated to be an allergen in this study. Additional study to detect specific allergens related to jellyfish allergy would be particularly useful to specify disease phenotypes and individual care in future.
