D Ozceker, M Bulut, A Celik Ozbay, F Dilek, M Koser, Z Tamay, N Guler
INTRODUCTION AND OBJECTIVES: Atopic dermatitis is a chronic, relapsing, highly pruritic, inflammatory skin disease characterized by typical localization with increasing prevalence of 10-20% in children. Pruritus is one of the major diagnostic criteria of atopic dermatitis and also the main complaint altering quality-of-life of affected patients, inducing and aggravating inflammation. Although pruritus is the absolute symptom of AD, the etiology has not been fully explained yet and current antihistamine therapies are ineffective...

Allergic conjunctivitis (AC) includes a wide spectrum of clinical entities characterized by different incidence, age of onset, natural course, clinical outcome and response to treatment. Taken together, they represent one of the most frequent ocular surface diseases affecting more than 30% of the young-adult population and show an increasing incidence over the years. Moreover, comorbidities with other systemic atopic conditions such as asthma, atopic dermatitis and rhinitis require a multidisciplinary approach...

BACKGROUND: Eczema coxsackium (EC) can manifest in patients with underlying atopic dermatitis (AD) as a diffuse vesicular rash in a febrile child. The presentation overlaps clinically with the feared diagnosis of eczema herpeticum (EH), which makes differentiating between the conditions very important. CASE PRESENTATION: A 6-month-old girl with known AD presented with fever and rapidly spreading vesicular rash. The patient had multiple exposures including a new antibiotic prescription, introduction of new foods, 6-month vaccinations and a sick contact...

We report an 8-year-old boy with Netherton syndrome who was misdiagnosed and treated as severe atopic dermatitis. The diagnosis of Netherton syndrome was not made until the child was 8 years of age. We discuss the pitfalls in the diagnosis and alert physicians to the proper and early diagnosis of this syndrome. The child was treated with a low dose (0.25 mg/kg) of oral acitretin and a topical moisturizer with marked improvement of his skin and pruritus in 2 months. At 6-month follow-up, the skin was almost clear of erythema and scaling, and the hair was longer and stronger...

Erythematotelangiectatic rosacea is the most prevalent rosacea subtype. Multiple dermatologic conditions may mimic erythematotelangiectatic rosacea. The authors review a comprehensive approach to evaluating subjects with a suspected diagnosis of erythematotelangiectatic rosacea and discuss findings that may warrant further investigation. Differential diagnoses can be narrowed based on the presence of characteristics such as transient erythema, nontransient erythema, and telangiectasias. A thorough history and physical examination are critical in ruling out conditions such as dermatomyositis, lupus erythematosus, atopic dermatitis, and seborrheic dermatitis...

BACKGROUND: Cross-reactive carbohydrate determinants (CCD) are defined carbohydrate portions of glycoprotein cell surface molecules common to many plant and insect species. Mammalian species recognize CCD as foreign antigens and can mount humoral immune responses against them. Approximately 20-37% of grass and venom allergic people possess circulating IgE against CCD; these antibodies are generally considered clinically irrelevant. Anti-CCD IgE is, however, recognized as a cause of false positive, clinically incongruent serum allergen test results in people; this phenomenon has not been investigated in animals...

Atopic dermatitis (AD), or eczema, is a chronic inflammatory skin condition characterized by relapsing pruritic and dry, scaly lesions. AD affects 10% to 20% of children in the United States and significantly affects the quality of life of patients and their families. Primary care providers (PCPs) are often the first point of contact for the management of AD symptoms. As many as 70% of patients with mild to moderate disease can be managed by a PCP, underscoring the need for these providers to understand basic AD pathophysiology and current standards of care...

Atopic dermatitis (DA) is a chronic inflammatory skin disease. Its incidence and prevalence is increasing, especially in industrialized countries. The prevalence of AD in adults is estimated at 1-3 % of the general population and can present as adult-onset AD, or as infantile/childhood AD that persists, or recurs in adulthood. There are no specific diagnostic criteria for adult AD. Diagnosis may be also complicated by the fact that the clinical manifestations sometimes differ from pediatric AD. Moreover, many recent studies have identified adult AD as a systemic disease...

Introduction: Daptomycin is a cyclic lipopeptide that is bactericidal against Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA), vancomycin-intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA) strains. Daptomycin exerts its antimicrobial effect by a calcium-dependent interaction with the cytoplasmic membrane resulting in depolarization, ion loss and rapid cell death. Unfortunately, loss of daptomycin susceptibility in S. aureus in the clinical setting has been noted...

Atopic dermatitis is a chronic inflammatory skin disease. The objective of this study was to characterize the burden of atopic dermatitis in Japanese adult patients relative to the general population. Japanese adults (≥18 years) with a self-reported diagnosis of atopic dermatitis and adult controls without atopic dermatitis/eczema/dermatitis were identified from the 2013 Japan National Health and Wellness Survey. Atopic dermatitis patients were propensity-score matched with non-atopic dermatitis controls (1:2 ratio) on demographic variables...

Periorificial dermatitis (POD) has been documented in the pediatric population in patients as young as 3 months, with a slight predominance in girls compared to boys. Many patients have a personal or family history of atopic disorders. Periorificial dermatitis typically presents with erythematous to flesh-colored papules and rarely pustules near the eyes, nose, and mouth. Although the etiology is unknown, many patients have had recent exposure to a topical or less commonly an inhaled or systemic corticosteroid...

BACKGROUND: Routinely collected electronic health data (RCD) obtained for administrative and clinical purposes are increasingly used to study atopic dermatitis (AD). Methods for identifying AD patients in RCD differ, and it is unknown how this might affect study results. OBJECTIVES: We sought to evaluate how AD patients have been identified in studies using RCD, to determine whether these methods were validated, and to estimate how the method for identifying AD patients affected variability in prevalence estimates...

BACKGROUND: Antihistamines are often used to treat pruritus associated with atopic dermatitis (AD) despite lack of evidence for their efficacy. The American Academy of Dermatology does not recommend the general use of antihistamines in the management of AD, although the value of short-term sedating antihistamine use for insomnia secondary to itch is recognized. OBJECTIVE: To assess the use of sedating and non-sedating antihistamines for AD from 2003-2012. METHODS: The National Ambulatory Medical Care Survey (NAMCS) provided data on physician visits from 2003-2012...

Patients with atopic dermatitis (AD) have increased penetration of allergens, immune dysregulation (including shared cytokine pathways), and frequent use of emollients and topical medications, all of which may predispose toward developing allergic contact dermatitis (ACD). Recent systematic reviews have suggested that ACD is a significant clinical problem in both children and adults with AD. While this remains controversial, ACD remains an important comorbidity and potential exacerbant of AD in clinical practice...

Food allergy is immediate hypersensitive reactions to ingested foods. Since early diagnosis is effective for disease control, development of an objective diagnostic index is required. Using mediator-lipidomics, we found that levels of the urinary prostaglandin D2 (PGD2) metabolite, tetranor-PGDM, reflected the severity of the allergic symptoms and intestinal mast cell hyperplasia in mice. Repeated oral challenges with ovalbumin promoted allergic symptoms in sensitized mice. Particularly, the allergic mice presented with increased numbers of intestinal mast cells, which strongly expressed hematopoietic PGD synthase (H-PGDS)...

BACKGROUND: Conflicting data have been published on whether an association exists between atopic dermatitis (AD) and nonmelanoma skin cancer. This study aimed to determine whether individuals with AD had an increased risk of squamous cell carcinoma (SCC) development. METHODS: We conducted a retrospective, case-control study of patients residing in Olmsted County, Minnesota. Cases were selected from patients seen at Mayo Clinic (Rochester, Minnesota) who had an initial SCC diagnosis (either invasive SCC or SCC in situ) from January 1, 1996, through December 23, 2010...
