RESUMEN
Contact dermatitis (CD) is a common inflammatory skin disease caused by exposure to contact allergens and irritants. It is also the most common reason of occupational dermatitis and contributes greatly to hand dermatitis and facial dermatitis. Besides the two major forms of contact dermatitis: allergic contact dermatitis and irritant contact dermatitis, other subtypes of CD have been recognized including immediate skin reactions, photoinduced contact dermatitis, systemic contact dermatitis, and non-eczematous contact dermatitis. CD is a great imitator which can mimic many kinds of skin diseases, such as atopic dermatitis, lichen planus, and angioedema. For the diagnosis of CD, a complete medical history, including occupational history, is very important. It can give a clue of CD and provide a list of suspected substances. Besides the well-known diagnostic test, patch testing, there are many other diagnostic tests can be used to help diagnosis of CD and identify the causative allergens, including photopatch test, skin tests for detecting of immediate contact reactions, serum allergen-specific IgE test, and qualitative and quantitative testing of allergen in the suspected materials patients exposed to and challenge test. Before the treatment, the suspected irritants or allergens should be avoided completely. This includes both the removal of the patient from the environment that contains those substances and the promotion of the metabolism and expulsion of the allergens that have been absorbed by the body. In addition, it is also important to restore the skin barrier and reduce skin inflammation through multiple treatments, such as emollients, topical corticosteroids, and antihistamines, as well as systemic corticosteroids and immunosuppressants. Early and appropriate treatments are important to prevent further deterioration and persistence of the skin condition.

Contact dermatitis (CD) is caused by environmental agents, irritants, and allergens that penetrate the epidermis and lead to inflammation. An intact skin barrier prevents penetration and is important in maintaining healthy skin. Classical diagnosis of CD is made using the patch test, and traditional treatment strategies for CD promote skin barrier integrity and resolve the inflammatory component of the condition. This can be achieved by using emollient-based therapy, which is most important for skin barrier repair, and in addition to topical glucocorticosteroids, which are used in severe cases of CD and are most effective in reducing inflammation. Preventative measures, such as irritant and allergen avoidance in the workplace, also play a pivotal role in effective CD management. Moreover, CD management necessitates a holistic approach that incorporates prevention, barrier repair, and inflammatory resolution to ensure optimized efficacy. It is also important to consider potential barriers to optimal management when evaluating individuals with CD, such as limited patient education or poor access to care. Finally, key literature and our own clinical practice experience have highlighted the value of patient preference, as well as safety, efficacy and simplicity, in building the perfect emollient.

We report on four pediatric patients who presented with localized dermatitis in areas subject to repetitive friction due to their sitting positions. We propose that the cause of the eruption was irritant contact dermatitis due to frequently sitting in a crossed-leg sitting position, an entity for which we have coined the term pediatric positional sitting dermatitis (PPSD). The goal of this report is to raise clinicians' awareness of PPSD, which to our knowledge has not been previously described, and to discuss management of these patients.

Los corticoides son fármacos ampliamente utilizados en la práctica clínica, especialmente de forma tópica en dermatología. Estas sustancias pueden actuar como alérgenos y producir tanto reacciones de hipersensibilidad inmediata como retardada. La alergia en forma de dermatitis de contacto es la reacción más frecuente, y debe estudiarse mediante pruebas epicutáneas en unidades especializadas. Actualmente la batería estándar española tiene buenos marcadores para su detección, pero no ideales. Por ello, es rentable aplicar una batería específica de corticoides si dichos marcadores son positivos, así como los corticoides propios aportados por los pacientes. En cuanto a las reacciones de hipersensibilidad inmediata, son mucho menos habituales, pero potencialmente más graves. Debido a que estos fármacos son necesarios en múltiples enfermedades, es importante confirmar la sensibilización a estas sustancias, y orientar el uso de corticoides alternativos. En el presente artículo pretendemos revisar los principales conceptos respecto a estos 2 tipos de reacciones de hipersensibilidad en la alergia a corticoides, así como su abordaje en la práctica clínica
Corticosteroids are widely used drugs in the clinical practice, especially by topic application in dermatology. These substances may act as allergens and produce immediate and delayed hypersensitivity reactions. Allergic contact dermatitis is the most frequent presentation of corticosteroid allergy and it should be studied by patch testing in specific units. The corticosteroids included in the Spanish standard battery are good markers but not ideal. Therefore, if those makers are positive, it is useful to apply a specific battery of corticosteroids and the drugs provided by patients. Immediate reactions are relatively rare but potentially severe, and it is important to confirm the sensitization profile and to guide the use of alternative corticosteroids, because they are often necessary in several diseases. In this article we review the main concepts regarding these two types of hypersensitivity reactions in corticosteroid allergy, as well as their approach in the clinical practice

Sensitive skin is less tolerant to frequent and prolonged use of cosmetics and toiletries. It is self-diagnosed and typically unaccompanied by any obvious physical signs of irritation. With the change in lifestyle and also with increased opportunity to use many new brands of cosmetics and toiletries, there has been an increase in females complaining of unique sensation in their facial skin. Sensitive skin presents as smarting, burning, stinging, itching, and/or tight sensation in their facial skin. The condition is found in more than 50% of women and 40% of men, creating a sizable demand for products designed to minimize skin sensitivity. Good numbers of invasive and non-invasive tests are designed to evaluate and predict the sensitive skin. Management includes guidelines for selecting suitable cosmetics and toiletries in sensitive skin individuals.

Dermatitis papulosa juvenilis, also referred to as frictional lichenoid eruption, summertime lichenoid dermatitis of the elbows, Sutton's summer prurigo, recurrent papular eruption of childhood, and sandbox dermatitis, has been reported previously only in children. We describe three cases of DPJ in adults, which were confirmed by clinical and histology investigations. The term 'dermatitis papulosa adultorum' is suggested for this condition in adults.

Although the fields of bibliometrics and citation analysis have existed for many years, relatively few studies have specifically focused on the dermatological literature. This article reviews citation-based research in the dermatology journals, with a particular interest in manuscripts that have included Contact Dermatitis as part of their analysis. Overall, it can be seen that the rise of bibliometrics during the mid-20th century and its subsequent application to dermatology has provided an interesting insight into the progression of research within our discipline. Further investigation of citation trends and top-cited papers in skin research periodicals would certainly help complement the current body of knowledge.

BACKGROUND: The occupational contact dermatitis disease severity index (ODDI) was designed to assess the severity and importantly the functional disability caused by occupational contact dermatitis (OCD) of the hands in patients attending our occupational dermatology clinic. OBJECTIVES: To investigate the accuracy of the ODDI. PATIENTS/METHODS: Of 205 patients, 95 were assessed as having OCD of the hands. Content validity was assessed by content mapping and expert opinion. Construct validity was examined through comparing the ODDI against global clinical dermatology severity assessment (GCDSA). Intraobserver reliability, interobserver reliability, internal consistency, acceptability and convenience were also assessed. RESULTS: The ODDI was found to have content validity by the experts and was moderately correlated with GCDSA, supporting construct validity (Pearson's r = 0.54; P < or = 0.01). The ODDI was shown to be reliable with substantial agreement for both intraobserver reliability [intraclass correlation coefficient (ICC) = 0.62] and interobserver reliability (ICC = 0.75). Internal consistency within the ODDI was almost perfect (ICC = 0.94-0.99) and user survey showed the ODDI to be acceptable, easy and quick to use. CONCLUSIONS: The ODDI is a valid and reliable instrument to assess the severity and functional limitations caused by OCD, in patients who have had treatment or modified work duties, associated with some improvement of their dermatitis.

BACKGROUND AND OBJECTIVES: Hand eczema is a chronic disease with negative impact on quality of life (QoL). In this study, QoL in hand eczema patients is assessed and related to age, sex, severity, and diagnostic subgroups. METHODS: A total of 416 patients with hand eczema from 10 European patch test clinics participated in the study. Data on QoL were obtained from a self-administered questionnaire using the Dermatology Life Quality Index (DLQI). Severity was assessed by a scoring system (Hand Eczema Severity Index, HECSI) as well as frequency of eruptions and sick leave due to hand eczema. RESULTS: No significant difference was found between males and females with respect to QoL [DLQI median values and 25/75 percentiles for males and females being 7.0 (3-14) and 8.0 (3-13), respectively], although males were more severely affected than females (P < 0.025). A significant positive correlation was found for hand eczema severity and age (P < 0.001), while no significant correlation was found for QoL and age. QoL was found increasingly reduced when sick leave was getting higher (P < 0.001). A statistically significant correlation between QoL (as measured by DLQI) and hand eczema severity as measured by HECSI was found (P < 0.001). No significant difference in QoL was found between diagnostic subgroups. CONCLUSIONS: QoL was found markedly negatively affected in hand eczema patients and was significantly correlated to disease severity. No significant difference in QoL was found between males and females, in spite of significantly more severe eczema in males, indicating that QoL in female patients is more easily affected.

INTRODUCTION: Dermatologic diseases of the vulva may cause dyspareunia. These disorders may be overlooked by gynecologists and urologists because of lack of residency training experience. Dermatologists who are most familiar with these diseases are infrequently trained in vulvovaginal examination. As such, these disorders are often improperly diagnosed and treated. AIM: To describe the presentation and management of the major vulvar dermatoses including irritant and allergic contact dermatitis, lichen sclerosus, lichen simplex chronicus, and lichen planus. MAIN OUTCOME MEASURE: Data from a peer review literature search on the topic of vulvar dermatoses. METHODS: The literature for this review article was obtained through a Medline search. Appropriate dermatology textbooks were utilized for additional information. RESULTS: A comprehensive survey of the vulvar dermatoses. CONCLUSION: Vulvar dermatoses must be considered a part of the differential diagnosis of any woman with a sexual pain disorder. As such, healthcare providers who evaluate and treat women with dyspareunia must become familiar with the most common dermatologic disorders of the vulva.

BACKGROUND/AIMS: The International Contact Dermatitis Research Group (ICDRG) system for clinical scoring of allergic patch test reactions is well established in clinical dermatology for detailed scoring of allergic reactions. The degree of redness and the presence of swelling, papules, vesicles and bullae are assessed based on visual examination and palpation of reactions. In photographic assessment used in research and tele-dermatology, the scoring is solely based on visual examination of photos. The aim of the study was to evaluate inter-expert variation in patch test reading using photographic images, with ICDRG reading as a reference. MATERIAL AND METHODS: Five experienced senior dermatologists each scored 55 positive patch test reactions from 16 slides in an office environment. The slides showed pictures of patch tests with different allergens. The scoring system by ICDRG with six categories for scoring was used. RESULTS: The five dermatologists performed the scoring very differently. When the scoring system was simplified to a tripartite scoring system, the scoring was performed almost similarly by the five clinicians. CONCLUSION: Based on the present results, it is proposed that the number of scoring categories should be minimized and simplified into negative (including doubtful) reactions, positive reactions and irritant reactions. Such simplified tripartite reading is proposed for research purposes and for tele-dermatology, when scoring is based on photographic images.

BACKGROUND: In the USA, Europe and Japan 40 to 50% of women report that they have sensitive skin, defined as abnormal sub-clinical sensory responses to drugs, cosmetics and toiletries in the absence of visible signs of irritation. Itching, burning, stinging and tightness are the commonest complaints, which mainly afflict women. Manufacturers of skin care products have made available a large variety of products which are designed for persons with sensitive skin. Such products are not required by regulatory agencies to submit evidence of safety and efficacy, allowing marketers to make claims that are often exaggerated, irrational and even preposterous. The consumer with self-assessed sensitive skin has no way of judging which products are likely to be most beneficial and least harmful. The marketplace is awash with products for which there is no evidence that the rosy claims have been substantiated by appropriate testing procedures. There is no internationally accepted consensus regarding the criteria which define sensitive skin. Many papers have been published in the last 15 years, mainly originating from industry, which express widely differing views regarding what constitutes sensitive skin. For some, any adverse reaction to a product topically applied to sensitive skin, including breakouts, redness, scaling etc., a panoply of adverse reactions which is virtually meaningless. Others include environmental factors as causative, including cold, dry wind, heat and high humidity, solar radiation, etc., which add to the manifest complexities of the subject. METHODS: This is the first paper in a series which provides a comprehensive review of the subject, emphasizing the all too many controversies and confusions arising from the lack of a consensus regarding the identification, classification, epidemiology, prevalence and pathogenesis of sensitive skin. Sensitive skin is a biologic reality and not a psychological, fashionable fantasy on the part of impressionable women. RESULT/CONCLUSION: There is an urgent necessity to establish rigorous methodologies for estimating the quality and severity of sensitive skin, a heterogeneous condition involving multi-factorial factors. Subsequent papers in this series will describe in detail the experimental approach our group has used to bring some clarity and credibility to this querulous, but important subject.
