Abstract
Current research in food science has explored the influence of front-of-package (FOP) labeling systems on consumer decision-making, yielding mixed results. We suggest that these inconsistent findings regarding FOP labeling effectiveness stem from a failure to consider a pivotal individual-level variable: consumer susceptibility to FOP labeling (CSFL). In the present research, we define this focal construct and develop and psychometrically validate a seven-item instrument that captures the construct across six studies (N = 1134). The current research may assist in segmenting consumers based on their susceptibility to FOP labeling, thereby facilitating the creation of targeted interventions tailored to this individual difference. Notably, the CSFL scale is positively correlated with consumers' willingness to purchase food items with genuine, third-party FOP labels, but not products lacking labels or products with fictitious FOP labels. This supports the predictive validity of the scale in determining important consumption-related outcomes.

Abstract
The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research.

Abstract
This paper explores the impact of health communication using smartphones and the outcome of healthier purchases when young Thai consumers shop for groceries. A conjoint experiment was arranged whereby participants (n = 214) purchased grocery using information conveyed via quick response (QR) codes. Results show that a healthy food label, and a good consumer rating on the food's health, evoked the consumers' tendencies towards interacting with a smartphone in the purchasing situation. In addition, likelihood of buying increased. Further simulations revealed that health communication conveyed via QR codes can be a good investment for brands to increase healthier purchases.

Abstract
IntroductionUnhealthy food consumption is a problem for society, companies, and consumers. This study aims to contribute to knowledge regarding such issues by investigating how technology-enabled healthy food labels can impact food choice in an online grocery store context. We conceptualized unhealthy and healthy food choice as a matter of impulsivity problems. Three technology-enabled healthy food labels were derived based on variables that might impact self-control, and their influence on food choice was investigated.MethodsThe empirical study consisted of three parts. In the first part, participants’ impulsivity was measured using an adjusting delay task. Part two investigated the effects of self-monitoring, pre-commitment, and social comparison-based technology-enabled healthy food labels on food choice in a hypothetical online grocery shopping setting using a choice-based conjoint experiment. Lastly, in the third part, three where demographical questions were asked.ResultsThe results (n = 405) show that self-monitoring, pre-commitment, and social comparison-based technology-enabled healthy food labels had the most to least impact on food choice in that order. Furthermore, the results indicate that self-monitoring and pre-commitment labels had more impact on the choice for impulsive compared to non-impulsive participants. Similarly, the results indicate that social comparison had more impact on choice for non-impulsive participants. These findings suggest that self-monitoring of previous healthy food choices might be more effective than pre-commitment based on discounts for healthy food products. However, these differences were minor.DiscussionThis finding has managerial implications as grocery stores might increase their revenue by introducing self-monitoring labels in an online grocery shopping setting. Future research should investigate these technology-enabled healthy food labels in natural food purchase settings.

Abstract
Academia and business have shown an increased interest in using neurophysiological methods, such as eye-tracking and electroencephalography (EEG), to assess consumer motivation. The current research contributes to this literature by verifying whether these methods can predict the effects of antecedent events as motivating functions of attention, neural responses, choice, and consumption. Antecedent motivational factors are discussed, with a specific focus on deprivation as such a situational factor. Thirty-two participants were randomly assigned to the experimental and control conditions. Water deprivation of 11-12 h was used as an establishing operation to increase the reinforcing effectiveness of water. We designed three experimental sessions to capture the complexity of the relationship between antecedents and consumer behavior. Experimental manipulations in session 1 established the effectiveness of water for the experimental group and abolished it for the control group. Results from session 2 show that participants in the experimental group had significantly higher average fixation duration for the image of water. Their frontal asymmetry did not provide significant evidence of greater left frontal activation toward the water image. Session 3 demonstrated that choice and consumption behavior of the relevant reinforcer was significantly higher for participants in the experimental group. These early findings highlight the potential application of a multi-method approach using neurophysiological tools in consumer research, which provides a comprehensive picture of the functional relationship between motivating events, behavior (attention, neural responses, choice, and consumption), and consequences.

Abstract
Since retailers control the space where consumers tend to make the vast majority of their food purchase decisions, they can take measures to promote healthy living. Increasing relative sales of healthy food can contribute to the ongoing battle against preventable lifestyle diseases. We show how retailers can use impression management and environmental cues in their stores to influence consumers' sales responses to healthy food. This paper advocates in-store research in this realm and introduces three consumer behavior levels - reaching, stopping/holding, and closing the sale - as micro-conversions when retailers use impression management on their consumers. We showcase impression management at each conversion level by testing the effects of placing healthy and unhealthy food items on a floor display in the store area with the most traffic, with or without background music and an advertisement. The results demonstrate that a healthy food product can outperform the sales of popular unhealthy foods. The floor display, for example, increased the sales of the targeted "healthy product" by 570% on average during the intervention periods, compared with the baseline. We discuss the importance of in-store research into three conversions to enable further development of impression management and the use of environmental cues for healthy food promotion.

Abstract
The broad differential diagnosis of neonatal erythroderma often poses a diagnostic challenge. Mortality of neonatal erythroderma is high due to complications of the erythroderma itself and the occasionally severe and life-threatening underlying disease. Early correct recognition of the underlying cause leads to better treatment and prognosis. Currently, neonatal erythroderma is approached by a case by case basis. The purpose of this scoping review was to develop a diagnostic approach in neonatal erythroderma. After a systematic literature search in Embase (January 1990 - May 2020, 74 cases of neonatal erythroderma were identified, and 50+ diagnoses could be extracted. Main causes were the ichthyoses (40%) and primary immunodeficiencies (35%). Congenital erythroderma was present in 64% (47/74) of the cases, predominantly with congenital ichthyosis (11/11; 100%), Netherton syndrome (12/14, 86%), and Omenn syndrome (11/23, 48%). Time until diagnosis ranged from 102 days to 116 days for cases of non-congenital erythroderma and congenital erythroderma respectively. Among the 74 identified cases a total of 17 patients (23%) died within a mean of 158 days and were related to Omenn syndrome (35%), graft versus host disease (67%), and Netherton syndrome (18%). Disease history and physical examination are summarized in this paper. Age of onset and a collodion membrane can help to narrow the differential diagnoses. Investigations of blood, histology, hair analysis, genetic analysis and clinical imaging are summarized and discussed. A standard blood investigation is proposed and the need for skin biopsies with Lympho-Epithelial Kazal-Type related Inhibitor-staining is highlighted. Overall, this review shows that diagnostic procedures narrow the differential diagnosis in neonatal erythroderma. A 6-step flowchart for the diagnostic approach for neonatal erythroderma during the first month of life is proposed. The approach was made with the support of expert leaders from international multidisciplinary collaborations in the European Reference Network Skin-subthematic group Ichthyosis.

Abstract
Mass media extensively inform societies about events threatening the global food supply (e.g., pandemics or Brexit). Consumers exposed to such communication may perceive food resources as becoming scarcer. In line with an evolutionary account, these perceptions can shift decision-making in domains such as food preferences or prosociality. However, existing literature has solely focused on actual and past food insecurity experiences threatening mostly low-income families, thus neglecting the future-oriented perceptions among the general population. This paper broadens the food insecurity research scope by developing a new construct-anticipated food scarcity (AFS)-which is defined as the perception that food resources are becoming less available (in the future). We have developed and psychometrically validated the 8-item Anticipated Food Scarcity Scale (AFSS) in eight studies (N = 1333). The 8-item AFSS is unidimensional and has good psychometric qualities. The scale is sensitive to food scarcity cues and, therefore, can be used in experimental research. Moreover, its relatively narrow set of items makes it an exceptionally potent tool for use in online surveys, field settings, and lab studies. Taken together, the AFSS presents an alternative approach to food scarcity measurement in affluent societies and, consequently, can foster novel research on food waste, prosocial behaviors, and other similar topic areas.

Abstract
Background:Immune mediated inflammatory diseases (IMIDs) often have a chronic character and large impact on daily life of patients. In order to provide patient-centred care, insight in personal goals is a key issue.Objectives:The aim of this study was to evaluate treatment goals of patients with IMIDs over time.Methods:Patients with IMIDs were invited to complete a self-designed questionnaire about lifestyle, personal treatment goals and perceived care at their first visit to our centre and one year after referral. Clinical information was collected through the electronic patient record system.Results:41 (30%) patients of the 137 invited, completed both questionnaires. Participants had a mean age of 45.6 years (SD 13.4), N=35 (83%) was female, mean disease duration was 12.7 years (SD 12.7). Patients were diagnosed with connective tissue disease (CTD, n=19; 45%), antiphospholipid syndrome (APS, n=10; 24%), inflammatory arthritis (n=7; 17%) and psoriasis (n=7; 17%). We identified six categories of treatment goals: disease related, daily functioning, lifestyle, emotional wellbeing. Figure 1 shows the reported treatment goals at baseline and follow-up. Most frequently mentioned were goals related to disease, lifestyle and daily functioning. At follow-up we observed a vast increase in reported goals related to psychological wellbeing (from 5% to 16%). At baseline patients with APS chose lifestyle-related goals more often than other patients (RR=3.2; p=0.015). At follow-up patients with CTDs reported disease related-goals less often than other patients (RR=0.4; p=0.002). Patients did not report significant progress in reaching their goals on a Likert scale of 1-10. However, in 90% at first visit and in 83% of patients at follow-up, patients reported that the provided care was addressing issues they personally prioritized.Conclusion:IMID patients’ most frequent treatment goals relate to disease activity, lifestyle and daily functioning. Patients frequently change their treatment goals during the first year of treatment. Better understanding of personal goals can help physicians providing targeted and personalised medicine.Figure 1.themes of treatment goals at baseline and follow-upAcknowledgements:The researchers would like to thank all patients participating in this study and acknowledge the UMC Utrecht research program Infection and Immunity for supporting this initiative.Disclosure of Interests:None declared

Abstract
BACKGROUND Identifying patients with sentinel node (SN)-negative melanoma who are at greatest risk of recurrence is important. The European Organization for Research and Treatment of Cancer (EORTC) Melanoma Group proposed a prognostic model that has not been validated in population-based data. The EORTC nomogram includes Breslow thickness, ulceration status and anatomical location as parameters. The aim of this study was to validate the EORTC model externally using a large national data set. METHODS Adults with histologically proven, invasive cutaneous melanoma with a negative SN biopsy in the Netherlands between 2000 and 2014 were identified from the Dutch Pathology Registry, and relevant data were extracted. The EORTC nomogram was used to predict recurrence-free survival. The predictive performance of the nomogram was assessed by discrimination (C-statistic) and calibration. RESULTS A total of 8795 patients met the eligibility criteria, of whom 14·7 per cent subsequently developed metastatic disease. Of these recurrences, 20·9 per cent occurred after the first 5 years of follow-up. Validation of the EORTC nomogram showed a C-statistic of 0·70 (95 per cent c.i. 0·68 to 0·71) for recurrence-free survival, with excellent calibration (R2 = 0·99; P = 0·999, Hosmer-Lemeshow test). CONCLUSION This population-based validation confirmed the value of the EORTC nomogram in predicting recurrence-free survival in patients with SN-negative melanoma. The EORTC nomogram could be used in clinical practice for personalizing follow-up and selecting high-risk patients for trials of adjuvant systemic therapy.

Abstract
BACKGROUND A nomogram to predict sentinel node (SN) positivity [the Melanoma Institute Australia (MIA) nomogram] was recently developed and externally validated using two large single-institution databases. However, there remains a need to further validate the nomogram's performance using population-based data. OBJECTIVES To perform further validation of the nomogram using a European national patient cohort. METHODS Patients with cutaneous melanoma who underwent SN biopsy in the Netherlands between 2000 and 2014 were included. Their data were obtained from the Dutch Pathology Registry. The predictive performance of the nomogram was assessed by discrimination (C-statistic) and calibration. Negative predictive values (NPVs) were calculated at various predicted probability cutoffs. RESULTS Of the 3049 patients who met the eligibility criteria, 23% (691) were SN positive. Validation of the MIA nomogram (including the parameters Breslow thickness, ulceration, age, melanoma subtype and lymphovascular invasion) showed a good C-statistic of 0·69 (95% confidence interval 0·66-0·71) with excellent calibration (R2 = 0·985, P = 0·40). The NPV of 90·1%, found at a 10% predicted probability cutoff for having a positive SN biopsy, implied that by using the nomogram, a 16·3% reduction in the rate of performing an SN biopsy could be achieved with an error rate of 1·6%. Validation of the MIA nomogram considering mitotic rate as present or absent showed a C-statistic of 0·70 (95% confidence interval 0·68-0·74). CONCLUSIONS This population-based validation study in European patients with melanoma confirmed the value of the MIA nomogram in predicting SN positivity. Its use will spare low-risk patients the inconvenience, cost and potential risks of SN biopsy while ensuring that high-risk patients are still identified.

Abstract
BACKGROUND It has been claimed, without supporting evidence, that knowledge of sentinel node (SN) status does not provide more accurate prognostic information than basic clinicopathological features of a primary cutaneous melanoma. We sought to investigate this claim and to quantify any additional value of SN status in predicting survival outcome. PATIENTS AND METHODS Data for a Dutch population-based cohort of melanoma patients (n = 9272) and for a validation cohort from a large Australian melanoma treatment center (n = 5644) were analyzed. Patients were adults diagnosed between 2004 and 2014 with histologically-proven, primary invasive cutaneous melanoma who underwent SN biopsy. Multivariable Cox proportional hazards analyses were carried out in the Dutch cohort to assess recurrence-free survival (RFS), melanoma-specific survival (MSS) and overall survival (OS). The findings were validated using the Australian cohort. Discrimination (Harrell's C-statistic), net benefit using decision curve analysis and net reclassification index (NRI) were calculated. RESULTS The Dutch cohort showed an improved C-statistic from 0.74 to 0.78 for OS and from 0.74 to 0.76 for RFS when SN status was included in the model with Breslow thickness, sex, age, site, mitoses, ulceration, regression and melanoma subtype. In the Australian cohort, the C-statistic increased from 0.70 to 0.73 for OS, 0.70 to 0.74 for RFS and 0.72 to 0.76 for MSS. Decision curve analyses showed that the 3-year and 5-year risk of death or recurrence were more accurately classified with a model that included SN status. At 3 years, sensitivity increased by 12% for both OS and RFS in the development cohort, and by 10% and 6% for OS and RFS, respectively, in the validation cohort. CONCLUSIONS Knowledge of SN status significantly improved the predictive accuracy for RFS, MSS and OS when added to a comprehensive suite of established clinicopathological prognostic factors. However, clinicians and patients must consider the magnitude of the improvement when weighing up the advantages and disadvantages of SN biopsy for melanoma.

Abstract
The accurate delineation of various forms of business organization requires a comparative analysis of their objectives, functions, and organizational structures. In particular, this paper highlights differences in managerial work between business firms and non-profits exemplified by the charitable organization. It adopts as its template the theory of the marketing firm, a depiction of the modern corporation as it responds to the imperatives of customer-oriented management, namely consumer discretion and consumer sophistication. It describes in §2 the essentials of the theory and its basis in consumer behavior analysis, and outlines its unique position as the organization responsible for marketing transactions, based on objective exchange, competitive markets and prices, and the deployment of the entire marketing mix. §3 deals in greater depth with the objective, strategic functions, and organization of the marketing firm in terms of the concepts of metacontingency and bilateral contingency. §4 discusses how the marketing firm differs from charities in terms of goal separation, market-based pricing and competition, the entrepreneurial (strategic) process, the pursuit of customer-oriented management, and organizational structure. Particular attention is accorded the organizational differences between marketing firms and charities, which arise as a direct consequence of the distinct patterns of contingency they entail. §5 discusses the implications of the foregoing analysis and draws appropriate conclusions.

Abstract
The molecular background of a significant proportion of spitzoid neoplasms is still unknown. Recently, activating mutations in MAP2K1 have been described in a few spitzoid lesions, but not in benign Spitz nevi. We report four cases of melanocytic tumors with spitzoid features in which a MAP2K1 mutation was detected. The lesions did not show a single distinct phenotype and ranged from benign to malignant. Two cases resembled desmoplastic Spitz nevi. Based on the combination of morphological, immunohistochemical, and molecular findings, one case was classified as benign, one as probably benign, possibly intermediate low-grade (MELTUMP—melanocytic tumor of unknown malignant potential), one case was classified as intermediate (MELTUMP), and one case was considered a superficial spreading melanoma with spitzoid features. Based on this, we conclude that MAP2K1 mutations can indicate a spitzoid genetic signature and can be found in both benign and malignant spitzoid neoplasms.

Abstract
INTRODUCTION Although adjuvant therapy is available for melanoma patients with sentinel lymph node (SLN) metastases (pN+), this is not the case for thick melanomas without SLN involvement (pN-). OBJECTIVES We assessed overall and relative survival (OS, RS) in patients with >4.0 mm Breslow thickness (BT) pN- and pN + melanomas and ≤4.0 mm pN+ patients. MATERIALS AND METHODS Clinicopathological data were retrieved from a cohort of >4.0 mm thick and/or pN + melanoma patients in The Netherlands from 2000 to 2014. OS and RS was compared using Kaplan-Meier-curves. A Cox-regression-model was developed to assess determinants of OS in >4.0 mm pN- patients. RESULTS In 54 645 patients, 3940 (7.2%) had >4.0 mm thick melanomas. SLN biopsy was performed in 1150 (29.2%) patients. Five-year OS was 70.5% for >4.0 mm pN- and 48.1% for >4.0 mm pN+ patients (p < 0.001), with a decreasing trend in OS for every mm BT. Five-year OS in 1877 ≤ 4.0 mm pN+ patients was 71.5%, which was not different from >4.0 mm pN- (p = 0.24). Higher age, higher BT category, ulceration and male gender were significantly associated with poor survival in >4.0 mm pN- patients. CONCLUSIONS Thick pN- melanomas have a poor prognosis, comparable to that of less thick pN + melanomas, which is not accounted for in current guidelines. We encourage including these high-risk patients in adjuvant trials.

Abstract
Background Melanoma patients with intra‐nodal nevi (INN) and without melanoma metastasis in the sentinel lymph node biopsy (SLNB) are generally treated as patients with negative SLNB. However, diagnosis of INN may be difficult and nodal melanoma metastases may falsely be regarded as INN. Objectives Our aim was to evaluate the clinical significance of INN in the SLNB in patients with primary cutaneous melanoma on a nationwide level in The Netherlands by comparing survival between three groups: patients with INN and without nodal melanoma metastasis (INN group), patients without INN and without nodal melanoma metastasis (negative SLNB group) and patients with nodal melanoma metastasis irrespective of INN (positive SLNB group). Methods Data were obtained from ‘PALGA’, the Dutch Nationwide Network and Registry of Histopathology and Cytopathology, yielding a cohort of adults with histologically proven, primary, invasive cutaneous melanoma patients in The Netherlands diagnosed between 2000 and 2014 who underwent SLNB. Clinical and pathological variables were extracted from the pathology text files. Differences between patients with INN, negative SLNB and positive SLNB were analysed using Kaplan–Meier analysis. Results A total of 11 274 patients were eligible for inclusion. The prevalence of INN in the SLNB was 5.0%. Melanomas with INN had similar median Breslow thickness compared to melanomas with negative SLNB and were more frequently located on trunk and upper limbs and observed in younger patients compared to melanomas with negative and positive SLNB. Overall survival of patients with INN showed no significant difference compared with negative SLNB (median follow‐up of 5.7 years of all patients). Conclusions As there seems to be no difference in overall survival between patients with INN and negative SLNB, the diagnosis of INN seems to be reliable. Current practice to treat patients with INN as patients with negative SLNB appears to be appropriate.

Abstract
BACKGROUND In Europe, one of the highest melanoma incidences is found in the Netherlands. Like in several other European countries, females are more prone to develop melanoma as compared to males, although survival is worse for men. OBJECTIVE To identify clinicopathological gender-related differences that may lead to gender-specific preventive measures. METHODS Data from the Dutch Nationwide Network and Registry of Histopathology and Cytopathology (PALGA) were retrieved from patients with primary, cutaneous melanoma in the Netherlands between 2000 and 2014. Patients initially presenting as stage I, II and III without clinically detectable nodal disease were included. Follow-up data were retrieved from the Netherlands Cancer Registry. Gender-related differences were assessed, and to compare relative survival between males and females, multivariable relative excess risks (RER) were calculated. RESULTS A total of 54.645 patients were included (43.7% men). In 2000, 41.7% of the cohort was male, as compared to 47.3% in 2014 (P < 0.001). Likewise, in 2000, 51.5% of the deceased cohort was male compared to 60.1% in 2014 (P < 0.001). Men had significantly thicker melanomas at the time of diagnosis [median Breslow thickness 1.00 mm (interquartile range (IQR): 0.60-2.00) vs. 0.82 mm (IQR: 0.50-1.50) for females] and were significantly older at the time of diagnosis, more often had ulcerated melanomas and melanomas localized on the trunk or head and neck. Over time, survival for females improved while that of men decreased (P < 0.001). RER for dying was 1.37 (95% CI: 1.31-1.45) for men in multivariable analysis. CONCLUSION There are evident clinicopathological differences between male and female melanoma patients. After multivariable correction for all these differences, relative survival remains worse for men. Clinicians as well as persons at risk for melanoma should be aware of these differences, as awareness and prevention might lead to a lower incidence and mortality of melanoma. This indicates the need of prevention campaigns integrating and targeting specific risk profiles.

Abstract
The store is the main laboratory for in-store experimental analysis. This article provides an introduction to a research program aimed at improving research practices in this laboratory, particularly emphasizing the importance of behavioral data and the new opportunities that technology offers. This complex modern-day Skinner box has sets of well-studied stimuli-behavior interactions that constantly adapt to the latest economic environment and as such constantly stretch the boundaries of behavioral analytic theory. However, the retail setting is highly important to applied behavior analysis for such issues as health, debt, environmental conservation, animal welfare, self-control, and consumer protection in general. This article presents a research strategy that emphasizes key environmental touch points throughout the customer journey in grocery retailing. We highlight the latest development by examining a particular research case and discussing the need for behavioral economic understanding of the start of the grocery journey, that is, the consumer choice of in-store product carrying equipment (e.g., cart, basket, or nothing). The conceptual system consists of a molecular four-term contingency framework as well as a more molar approach with conversion-rate modeling, where actual choice behavior is detected through video surveillance. The data are analyzed using a Shopper Flow© Tracking System in which software is designed to provide automatic data on shopper behavior and to assist human observers in tracking individual shopping trips. We discuss behavioral classifications, methodology, and implications related to the data from consumer tracking efforts.

Abstract
The impact of complex environmental factors on consumer choices and preferences can be analyzed through the prism of consumer behavior analysis, whereas variations of marketing attributes and their impact on choice can be measured using conjoint analysis. Considering the case of the constantly growing online food selections, we discuss choice-based conjoint analysis and explore the opportunities for behavior analysts to examine the interrelationships of multiple variables and socially important choice settings, and to promote desired behaviors. We show a few examples of using trade-off analyses in online food retail to understand consumer behavior with respect to healthy food items. As demonstrated in these examples based on our own pilot research, conjoint analysis can be used for complex behavior-that which is not amenable directly to an experimental analysis-or as an efficient initial step before moving into further experiments or analyses using biometrics (e.g., eye-tracking) or web analytics conducted in different settings such as e-commerce, e-mail, social media, or on mobile platforms. This paper summarizes the personalized, data driven economic analysis that is possible with a choice-based conjoint analysis.

Abstract
BACKGROUND Food is one of the leading causes of anaphylaxis. In the Netherlands, patients visit a general practitioner (GP) as often as an emergency department (ED) in case of an acute food allergic reaction. So far, the management of food allergic reactions by GPs has not been investigated. Therefore, we explored the management of acute food allergic reactions by GPs regarding specific treatment, observation period, prescription of emergency medication to treat new episodes, diet advices and referral to a specialist. METHODS A questionnaire containing three hypothetical cases (two anaphylactic and one mild case) with questions about their management was sent to 571 GPs. RESULTS Overall, treatment choice was dependent on the severity of the reaction (mild vs. anaphylaxis, P < .001). However, epinephrine was used for treatment of anaphylaxis with mainly respiratory symptoms in only 27% and for anaphylaxis with mainly cardiovascular symptoms in 73%. At discharge, the percentages for prescription of self-injectable epinephrine were 53% and 77%, respectively. A short observation period of <2 hours was advised by 42% of general practitioners in case of anaphylaxis. CONCLUSIONS Treatment of food induced anaphylaxis by GPs appears to be suboptimal: a considerable number of patients would not be treated with epinephrine for the acute reaction (especially anaphylactic cases with respiratory symptoms), the observation period chosen by GPs was often too short and self-injectable epinephrine was not always prescribed at discharge to treat possible new episodes. Education programs are needed to increase the awareness of GPs to recognize and treat anaphylactic reactions.

Abstract
An in-store experiment was performed to investigate the effects of shelf placement (high, middle, low) on consumers' purchases of potato chips. Placement of potato chips on the middle shelf was associated with the highest percentage of purchases. The results confirm the importance of item placement as a factor in consumers' buying behavior.

Abstract
In Sweet's syndrome, the essential features are the characteristic morphology of the lesions, their histologic appearance, the dramatic response to corticosteroids and the absence of scarring. We report an 8-month-old infant in whom Sweet's syndrome was diagnosed and who developed acquired cutis laxa in the skin lesions.

Abstract
BACKGROUND AND STUDY AIMS The first cases of squamous cell carcinoma in esophageal lichen planus were recently described. We performed a study to establish the prevalence of endoscopic and histopathologic abnormalities consistent with lichen planus and (pre-) malignancy in a cohort of patients with lichen planus. PATIENTS AND METHODS A total of 24 patients with lichen planus were prospectively studied using high-magnification chromoendoscopy. Focal esophageal abnormalities were mapped, classified, and biopsied. Biopsies were also taken from normal-appearing esophageal mucosa at three levels (proximal, middle, and distal). The presence of a lymphohistiocytic interface inflammatory infiltrate and Civatte bodies (i. e. apoptotic basal keratinocytes) at histopathologic examination was considered diagnostic for esophageal lichen planus. Symptoms were assessed using validated questionnaires. RESULTS A total of 38 focal abnormalities were biopsied. These consisted of: layers of mucosa peeling off, hyperemic lesions, papular lesions, submucosal plaques/papules, a flat polypoid lesion, and segments of cylindrical epithelium. No endoscopic signs of dysplasia were present. Esophagitis consistent with gastroesophageal reflux disease was noted in 12 / 24 patients. Histopathology showed chronic inflammation of the esophageal mucosa in the majority (18 / 24) of patients. In 50 % (12 / 24), the diagnosis of esophageal lichen planus was made. Dysplasia was not present. There were no differences in symptoms between patients with and without esophageal lichen planus. CONCLUSIONS At screening endoscopy a high prevalence (50 %) of esophageal lichen planus was found in patients with orocutaneous lichen planus. No dysplasia was found.

Abstract
The second revised practice guideline 'Acne' from the Dutch College of General Practitioners contains adequate and scientifically well-supported recommendations for the management of patients with acne. There are some concerns about the initial treatment steps in these guidelines which only allow very slow progress to systemic therapy. This might, in some cases, lead to inadequate treatment of patients with more severe acne.

Abstract
Inhibition of the epidermal growth-factor receptor (EGFR) is a new strategy in the treatment of solid malignancies. Two men, aged 65 and 59 years, with a metastasized renal carcinoma and a 51-year-old man with a metastasized melanoma developed an acneiform eruption during EGFR inhibition. The second and third patient also developed paronychia. Treatment in all patients consisted of antiseptics and topical antibiotics; the first and third patient also received an oral antibiotic. Withdrawal of the EGFR inhibitor because of progression of the disease led to complete recovery of the cutaneous lesions in the first and the third patient; both died after several months. In the second patient, the side effects reached an acceptable level during continued EGFR therapy. EGFR inhibition is usually accompanied by cutaneous side effects. An acneiform eruption is seen in up to 90% of all treated patients. Other side effects include dry skin, and nail and hair changes. The pathogenesis of these side effects is related to inhibition of EGFR signalling pathways in the skin, but is not yet fully understood. The treatment of EGFR inhibitor-mediated cutaneous toxicity is based mainly on clinical experience.

Abstract
BACKGROUND Home ultraviolet B (UVB) phototherapy is a debated treatment. It is currently being prescribed for patients with psoriasis, although literature on the subject is scarce. Despite the apparent contradiction between clinical practice and literature, no systematic study of either has been conducted. OBJECTIVES To assess and compare the available publications and guidelines about home UVB phototherapy for psoriasis with the actual opinions and use of this therapy. METHODS The literature and guidelines were searched using databases, search engines and e-mail. A postal survey of 343 Dutch dermatologists and 142 dermatologists from 32 other countries was carried out; 255 and 102 dermatologists respectively responded. Outcome measures were the reported advantages, drawbacks and prescription rates of home UVB phototherapy. RESULTS Fourteen publications (nonrandomized) and six guidelines concerning home UVB phototherapy for psoriasis were identified. Most were reticent about the use of this treatment. Publications describing nonclinical research (7/14) reported most of the drawbacks mentioned (24/31). Home UVB phototherapy was prescribed to 5% (median) of all patients with psoriasis in The Netherlands who required UVB. However, 28% (68/244) of the Dutch dermatologists prescribed home UVB in 20 to 100% of their cases. Dermatologists from other countries reported that 0-10% of UVB treatments were offered at home. For both Dutch and other dermatologists, the most important reasons for prescribing home UVB concerned time and travel distance (80%, i.e. 163 of 205 and 75%, i.e. 33 of 44). Therapy-related drawbacks (such as poor service and equipment) were the objections mentioned most often (55%, i.e. 103 of 186 and 63%, i.e. 57 of 91). Concerns about the medicolegal liability of home UVB were rarely expressed by individual respondents, but frequently mentioned in the various reports. CONCLUSIONS A discrepancy exists between the actual use of home UVB phototherapy and the general opinions found in publications. The treatment is prescribed for a considerable number of patients despite the fact that literature and guidelines advise caution. Personal and nonevidence-based opinions on this therapy are widespread while randomized clinical studies have thus far not been conducted.

Abstract
OBJECTIVE To determine the 6-month prevalence of body dysmorphic disorder (BDD) in outpatient clinics of dermatology and plastic surgery in a university medical centre. DESIGN Questionnaire study. METHOD In the period January 2004-June 2004, the self-reported Body dysmorphic disorder questionnaire was completed by 530 and 475 new patients in the outpatient clinics of dermatology and plastic surgery, respectively. The dermatologist or plastic surgeon assessed the severity of the defect. To meet the DSM-IV criteria for BDD, the patient must have been preoccupied with treatment of all or part of their appearance, experienced obvious suffering or restriction of function with minimal or no defect present (defect score 1 or 2). RESULTS In the outpatient clinics ofdermatology and plastic surgery 8.5% (95% CI: 6.1-10.9) and 3.2% (95% CI: 1.7-4.7) of patients screened positive for BDD, respectively. CONCLUSION A high prevalence of BDD was found in the outpatient clinics ofdermatology and plastic surgery. Because dermatologists and plastic surgeons do not often recognise BDD, a simple screening tool is needed.

Abstract
OBJECTIVE To determine trends in numbers of visitors and their demographic characteristics, reasons for visit, number of STDs and high-risk groups. DESIGN Secondary analysis of registration data. METHOD Data of every client that visited the STD clinic in Utrecht, the Netherlands, were aggregated from 1994 to 2002 in order to analyse trends. RESULTS The number of visitors as well as the number of STDs rose strongly over the period investigated. The age of the visitors decreased. In 1994 17% of the visitors was born outside the Netherlands, in 2002 6%. The majority of the clients (56%) visited the STD clinic to get themselves tested preventively and 27% came because of symptoms. Visitors with symptoms or who were warned by others had a three-fold increased risk of having an STD. Other risk groups were: homosexual men, visitors born outside the Netherlands and visitors who have had an STD before. Groups with an increased risk of having a Chlamydia trachomatis infection were: visitors aged under 34 years old and visitors born in Morocco, Surinam and the Antilles. The number of Chlamydia infections rose sharply among homosexual male visitors. CONCLUSION The increase in the number of visitors and of STD requires an increase in STD prevention, aimed at high-risk groups. More research is needed into the limited help-seeking behaviour of immigrants and more attention needs to be paid to Chlamydia trachomatis infections among homosexual men.

Abstract
A 58-year-old man with renal insufficiency, who was being treated by haemodialysis, developed progressive skin lesions. He had thickening and hardening of the skin at the extremities and swelling of the toes and fingers with flexion contractures. His face was not affected. Laboratory evaluation was unremarkable and a skin biopsy [table: see text] showed an increase of collagen and mucin, without an inflammatory infiltrate. These clinical features resemble a recently reported new disorder: nephrogenic fibrosing dermopathy. This disorder manifests as scleromyxedema-like cutaneous skin lesions without associated paraproteinemia, occurring in the setting of renal disease. The histopathologic features of nephrogenic fibrosing dermopathy, i.e. thickened collagen and mucin deposition, are unique. The incidence, prevalence and cause of the disease are unknown and there is currently no effective treatment. The Centers for Disease Control and Prevention (CDC) in the USA are calling on physicians who have encountered patients suffering from this type of lesions to contact the CDC for an intended control study.

Abstract
BACKGROUND There is a clear relationship between ultraviolet (UV) radiation (UVR) and the clinical manifestations of patients with lupus erythematosus (LE). Cutaneous lesions are induced or exacerbated by exposure to UVR. Of patients with LE, 24-83% are reported to be photosensitive to UVR. LE tumidus appears to be the most photosensitive subtype of LE, followed by subacute cutaneous LE (SCLE). In general, the history of patients with LE correlates poorly with the presence or absence of photosensitivity, due to a delayed time interval between UV exposure and exacerbation of skin lesions. Phototesting using artificial UVR and visible light is a reliable way of diagnosing photosensitivity. OBJECTIVES To investigate the photoreactivity of patients with various subtypes of LE using an individualized phototest protocol. The results of phototests were correlated with the history of photosensitivity, the subtype of LE, the presence of autoantibodies and the use of anti-inflammatory medication by these patients. METHODS Phototesting with UVA, UVB and visible light was performed in 100 patients with LE. The diagnosis of LE was established both on clinical examination and skin histology. Serological studies were also performed in all patients. The phototests were performed on large skin areas of the forearm or trunk; the first dose was twice the minimal erythema dose and the dosage was increased according to the individual reactions of the patients at the test sites. Follow-up of skin reactions at the test sites was performed for up to 2 months. Histological examination of the photoprovoked skin lesions was carried out in 57 patients. RESULTS Of the 100 patients included (81 women and 19 men; mean age 41 years, range 17-79), 46 had chronic discoid LE, 30 SCLE and 24 systemic LE. An abnormal reaction to UVR and visible light was found in 93% of our patients with LE. No clinical or histological evidence at the phototest sites of polymorphic light eruption was found. There was no correlation between photosensitivity and LE subtype, presence of autoantibodies or medical history. Concomitant use of anti-inflammatory medication seemed to exert only minimal influence on the results of phototesting. CONCLUSIONS When using an extended phototesting protocol, almost all patients with LE in this study showed clinical and histological evidence of aberrant photosensitivity. Therefore, patients with LE should receive thorough advice and instruction on photoprotective measures, regardless of their history, LE subtype or presence of autoantibodies.

Abstract
AIM To report on eight patients with severe idiopathic intermediate uveitis (IU) and granuloma annulare (GA), a self limiting cutaneous condition of unknown aetiology. METHODS Retrospective case series. Clinical ophthalmic and dermatological data were studied and fluorescein angiography and skin biopsies were reviewed. RESULTS All patients with idiopathic IU had similar ocular features (eight with vitritis, seven with retinal vasculitis) and developed complications such as cystoid macular oedema (n=5), cataract (n=4), and glaucoma (n=3). Systemic diseases were not found, but a localised type of GA was observed in all. CONCLUSION Seven out of eight patients with IU and GA developed severe retinal vasculitis. Further studies are needed for a better understanding of this association, a common pathogenesis, and its eventual clinical consequences.

Abstract
BACKGROUND Although knowledge concerning the impact of acne vulgaris on quality of life has increased in recent years, relatively few studies have assessed the effect of a change in clinical severity on psychosocial state. OBJECTIVE Assessment of the effect of a change in clinical acne severity on psychosocial state. METHODS This was investigated by means of questionnaires and clinical assessments by acne patients and dermatologists. Fifty females with mild to moderate facial acne were seen before and after a 9-month treatment with oral contraceptives. RESULTS The results showed a great variability in psychosocial impairment between individuals. After 9 months, a significant reduction in clinical severity was seen overall which did not relate to the significant improvements in self-esteem, stability of self-esteem and acceptance of appearance. CONCLUSION Perceived psychosocial impairment is individually based, is greater in women who subjectively overrate their acne and does not relate to clinical improvement.

OBJECTIVE We investigated the incidence and cause of erythroderma in an unselected population and evaluated the referral pattern of erythrodermic patients by nonacademic dermatologists. METHODS A survey was performed among all nonacademic dermatologists in The Netherlands, using a mailed questionnaire. Questions dealt with the number of patients diagnosed with erythroderma in the year 1997, the cause of the erythroderma, and whether these patients were referred to a university hospital. A questionnaire was also sent to all university hospitals. RESULTS Seventy-eight percent of the nonacademic dermatologists answered the questionnaire, and all 8 university hospitals responded. In the year 1997, 141 patients were diagnosed with erythroderma in The Netherlands. The annual incidence of erythroderma based on these figures is 0.9 patients per 100,000 inhabitants. Compared with the university hospitals, erythroderma was more often diagnosed as an exacerbation of preexisting dermatoses (61% vs 51%; P =.37) and less often as idiopathic (14% vs 31%; P =.04) among the nonacademic dermatologists. Cutaneous T-cell lymphoma was rarely the cause, occurring in only 1% of patients diagnosed by the nonacademic dermatologists but in 6% of patients at the university hospitals. Overall, only 37% of nonacademic dermatologists referred patients with erythroderma to a university hospital. CONCLUSIONS The incidence of erythroderma in The Netherlands is slightly lower than the earlier estimate in the literature. Moreover, the cause of erythroderma is different among patients diagnosed in an academic and a nonacademic setting. The majority of dermatologists in The Netherlands treat patients with erythroderma themselves and do not refer these patients to university hospitals.
