Clinical trials for systemic psoriasis therapy typically enroll healthy patients and exclude patients with cardiovascular disease, latent tuberculosis, liver disease, histories of malignancies, viral infections, children, and pregnant or breast-feeding women. Physicians often require guidance for optimum management of severe psoriasis in patients that have a combination of underlying disease states. To provide treatment recommendations for complex psoriasis scenarios, a consensus panel comprising 15 experts in psoriatic disease convened to review and discuss available evidence-based data and to arrive at a consensus for treatment options of difficult cases. An application of the Delphi Method was used to select case scenarios, provide medical treatment options, present the case study with existing medical evidence, and anonymously vote on treatment options. The top 10 treatment options were ranked and statistically analyzed to compare the differences between treatments. The final rankings and analysis provide guidance for practical, safe, and efficacious treatment options in a number of complex psoriasis scenarios

BACKGROUND: Studies show that balsam-restricted diets result in significant improvement of systemic contact dermatitis in patients with contact allergy to balsam of Peru (BOP). While tomatoes have been implicated as a frequent cause of BOP-related dermatitis, the presence of BOP in tomatoes has never been confirmed. OBJECTIVES: High-performance liquid chromatography coupled with mass spectrometry (liquid chromatography [LC]-MS) and UV spectrometry (LC-UV) was used to detect the possible presence of BOP constituents in tomatoes. METHODS: Samples of beefsteak, cherry, and plum tomatoes were extracted in ethyl acetate and analyzed with LC-MS and LC-UV for the presence of the following sensitizing constituents of BOP: benzoic acid, benzyl alcohol, trans-cinnamic acid, cinnamic alcohol, cinnamyl cinnamate, coniferyl alcohol, eugenol, isoeugenol, and methyl cinnamate. RESULTS: The initial LC-MS analysis of each tomato extract showed multiple peaks. Two of these peaks had molecular weights of 134 and 180, which correspond to cinnamic alcohol and coniferyl alcohol, respectively. The analysis did not show peaks corresponding to the molecular weights of the remaining compounds. Cochromatography of tomato extract with cinnamic alcohol and coniferyl alcohol using LC-UV further suggested the presence of these compounds in the tomato extract. CONCLUSION: Coniferyl alcohol and cinnamic alcohol, constituents of BOP, are present in beefsteak, cherry, and plum tomatoes

A 71-year-old man presented with a six-year history of a pruritic, erythematous, blistering eruption of the face, chest, and arms. Clinical findings, histopathologic features, and phototests were consistent with a diagnosis of chronic actinic dermatitis. The patient also had contact allergy and photocontact allergy to multiple allergens. A discussion of chronic actinic dermatitis is presented

A 79-year-old woman presented with a history of peeling of the palms and soles that began in young adulthood, with exacerbation after exposure to water. Her mother, 2 sisters, and a female maternal cousin have similar symptoms. Physical examination showed scale and hyperlinearity of the palms. Brief exposure to water initiated the development of 1-to 2-mm, translucent, white papules that were distributed diffusely on the palmar surface, with a concentration at the palmar margins and pressure points. Histopathologic examination showed an acanthotic epidermis with a central depression that was filled with compact orthokeratosis. The physical examination and histopathologic findings are consistent with a diagnosis of hereditary papulotranslucent acrokeratoderma

BACKGROUND: The 'gold standard' for diagnosing allergic contact dermatitis is patch testing. Previous studies have not adequately addressed the validity and usefulness of the North American Contact Dermatitis Group (NACDG) Standard 65-allergen series alone as a screening tool in the evaluation of contact dermatitis. OBJECTIVE: The purpose of this study is to examine the usefulness of the NACDG series of 65 allergens as an exclusive screening method in the diagnosis of contact allergy. METHODS: A retrospective chart review of 794 patients referred for patch testing with the NACDG Screening Series with or without additional allergens was performed to determine the number of positive patch-test results. The study groups were analyzed to identify whether the positive reactions were to allergens in the NACDG Standard Series or to allergens in the supplementary group. RESULTS: Of the 794 patients patch-tested between July 1, 2004, and July 1, 2006, 590 (74.31%) had a positive reaction to either an NACDG patch-tested allergen or a supplemental allergen; 386 (65.42%) patients testing positive for an allergen were positive to an NACDG allergen only, and 534 (90.51%) of the total positive reactors were positive for at least one NACDG test allergen. CONCLUSION: As a screening tool, the NACDG Standard Series is substantially more efficacious than are more limited standard series when used exclusively in the evaluation of patients with allergic contact dermatitis. More extensive testing, including testing with suspected supplementary allergens determined by thorough history and physical examination, can improve upon the NACDG series as a means to investigate the full causes of contact dermatitis in any individual patient

Corticosteroids are used to treat a variety of medical conditions. While topical preparations are known to commonly cause allergic contact dermatits, systemic use of these drugs rarely causes cutaneous reactions. (This paper presents) Two cases of (systemic) injectable corticosteroid use resulting in delayed hypersensitivity reactions are presented

Vaccines are responsible for the control of many infectious diseases that were once common in the United States, including polio, measles, diphtheria, pertussis (whooping cough), rubella (German measles), mumps, tetanus, and Haemophilus influenzae type b. National efforts to generate collaboration between federal, state, and local governments and public and private health care providers have resulted in record high levels of vaccination coverage in the United States. The high rate of US vaccinations is paralleled by growing concerns about the safety of their delivery. The variety of substances used in vaccines sometimes causes the development of cutaneous reactions in susceptible adults and children. This article will review adverse cutaneous events consistent with hypersensitivity reactions to the following ingredients in vaccines: aluminum, thimerosal, 2-phenoxyethanol, formaldehyde, and neomycin
