RESUMO
BACKGROUND: While the coexistence of vitiligo and Crohn's disease (CD) has been reported in individual patients, the epidemiological association between these autoimmune conditions remains inconclusive. OBJECTIVE: To assess the bidirectional association between vitiligo and CD. METHODS: A population-based study was performed to compare vitiligo patients (n = 20,851) with age-, sex- and ethnicity-matched control subjects (n = 102,475) regarding the incidence of new-onset and the prevalence of preexisting CD. Adjusted hazard ratios (HRs) and adjusted odds ratios (ORs) were calculated by multivariable Cox regression and logistic regression, respectively. RESULTS: The incidence rate of new-onset CD was evaluated at 3.6 (95% CI, 2.7-4.9) cases per 10,000 person-years (PY) in patients with vitiligo and 2.4 (95% CI, 2.0-2.9) cases per 10,000 PY in controls. Patients with vitiligo experienced an elevated risk of CD (fully adjusted HR, 1.60; 95% CI, 1.10-2.34; p = 0.015). Congruently, a history of preexisting CD predicted elevated odds of having subsequent vitiligo (fully adjusted OR, 1.49; 95% CI, 1.15-1.93; p = 0.002). Compared to other patients with vitiligo, those with vitiligo and comorbid CD were older and had a higher prevalence of diabetes mellitus, hyperlipidemia, and hypertension but a comparable all-cause mortality rate. CONCLUSIONS: The current study depicts a robust bidirectional association between vitiligo and CD. This knowledge is of clinical implication for physicians managing patients with both conditions. The diagnostic threshold for CD should be lowered in vitiligo patients with compatible symptoms.

BACKGROUND: The epidemiological relationship of vitiligo with systemic sclerosis (SSc) remains to be precisely evaluated. OBJECTIVE: To investigate the bidirectional association between vitiligo and SSc. METHODS: A population-based study was carried out to compare vitiligo patients (n = 20,851) with age-, sex- and ethnicity-matched control subjects (n = 102,475) regarding the incidence of new-onset and the prevalence of preexisting SSc. Adjusted hazard ratios (HRs) and adjusted odds ratios (ORs) were calculated by the Cox regression and logistic regression, respectively. RESULTS: The incidence rate of new-onset SSc was calculated at 2.4 (95% CI, 1.6-3.4) and 0.4 (95% CI, 0.3-0.6) cases per 10,000 person-years among patients with vitiligo and controls, respectively. Patients with vitiligo had an increased risk of SSc (fully adjusted HR, 5.37; 95% CI, 3.03-9.54; p < 0.001). Correspondingly, a history of SSc predicted elevated odds of developing vitiligo (fully adjusted OR, 2.09; 95% CI, 1.23-3.55; p = 0.006). Relative to other patients with vitiligo, those with vitiligo and comorbid SSc were older and had a higher prevalence of ischaemic heart disease, hyperlipidaemia, and hypertension. CONCLUSIONS: A robust bidirectional association exists between vitiligo and SSc. This knowledge is valuable for physicians managing patients with both conditions. Patients with vitiligo and comorbid SSc might be monitored for cardiovascular and metabolic comorbidities.

BACKGROUND: Epidemiological evidence regarding the course and activity patterns of hidradenitis suppurativa (HS) is yet to be delineated. OBJECTIVE: To identify activity patterns of HS throughout the time axis and to outline predictors of recalcitrant disease course. METHODS: A population-based retrospective cohort study was performed to follow patients with HS (n = 4417) throughout the initial 10 years following their diagnosis. The disease was considered active in a certain month if one of the following criteria was fulfilled: (i) purchase of an HS-related drug, (ii) admission to a dermatological ward and (iii) referral to a dermatological consultation in an emergency room. Patients with a recalcitrant disease were defined as those with ≥5 years of follow-up with ≥6 'active months' each. Patients with an indolent course were defined as those experiencing ≥9 years of follow-up with ≤1 'active months' each. RESULTS: The average (SD) number of months in which patients had an active disease was 1.37 (1.28) months per year. While 98 (2.2%) patients pursued a recalcitrant course, 1390 (31.5%) went through an indolent disease course. Older age (≥38 years; adjusted OR, 6.17; 95% CI, 3.33-11.43), Arab ethnicity (adjusted OR, 2.04; 95% CI, 1.20-3.48), low socioeconomic status (adjusted OR, 1.64; 95% CI, 1.03-2.60), obesity (adjusted OR, 3.47; 95% CI, 2.25-5.34) and smoking (adjusted OR, 2.65; 95% CI, 1.57-4.47) were found to independently predict recalcitrant course of HS. CONCLUSIONS: Mild course is more frequently encountered than severe course among Israeli patients with HS. Modifiable risk factors of recalcitrant course should be carefully addressed.

PURPOSE: The precise correction of refractive error is especially important in young adults. It is unclear whether cycloplegic refraction is necessary in this age group. The purpose of this study was to compare the non-cycloplegic and cycloplegic spherical equivalent (SE) refractive error measured in young adults. METHODS: This was a prospective study of 1400 eyes (n = 700) of enlisted soldiers aged 18 to 21 years who were consecutively evaluated in an outpatient army ophthalmology clinic. One drop of cyclopentolate 1 % was installed twice 10 min apart, and cycloplegic refraction was performed in both eyes 40 min later using an auto-refractor. The difference between non-cycloplegic and cycloplegic refractive measurements was analyzed. RESULTS: The mean difference in SE between non-cycloplegic and cycloplegic measurements was 0.68 ± 0.83 D (95 % CI, 0.64-0.72). Significantly greater differences were observed in hypermetropes than myopes (1.30 ± 0.90 D versus 0.46 ± 0.68 D, p < 0.001). Moderate hypermetropes (2 to 5 D) demonstrated significantly greater refractive error than mild (0.5 to 2 D) or severe (>5 D) hypermetropes (1.71 ± 1.18 D versus 1.19 ± 0.74 D and 1.16 ± 1.08 D respectively, p < 0.001). CONCLUSIONS: Young hypermetropic adults possessed +1 to +2 D of latent hypermetropia. In contrast, young myopic adults revealed pseudomyopia of -0.5 D. Cycloplegic refraction should be performed in young hypermetropic adults complaining of various signs of asthenopia.

CONTEXT AND OBJECTIVES: Cancer centers are increasingly providing complementary medicine as part of an emerging discipline termed 'integrative oncology' (IO). The present study explored factors associated with disparities in referral and adherence to a freely-provided IO program. METHODS: The databases of three oncology centers in northern Israel were searched retrospectively for chemotherapy-treated oncology patients eligible for referral by their oncology healthcare professionals to an integrative physician (IP) consultation. Demographic and cancer-related variables associated with the referral, and attendance by patients at the consultation were identified, as was adherence to the 6-week IO treatment program (high adherence, attending ≥4 IO treatment sessions; low adherence, 0-3 sessions). RESULTS: Of 4988 eligible patients, 1694 (34%) were referred to the IP consultation, with 1331 (78.6%) attending the consultation of which 766 (57.6%) were adherent to IO treatments. Multivariate analysis revealed lower referral rates among patients speaking primarily Arabic and Russian vs. Hebrew (OR = 3.0, 95% CI = 2.0-4.6, P < 0.0001); males vs. females (OR = 1.94, CI = 1.3-2.9, P = 0.001); those not reporting emotional distress (OR = 1.5, CI = 1.02-2.16, P = 0.037); and older age (OR = 1.04, CI = 1.03-1.06, P < 0.0001). Arabic and Russian-speaking patients were less likely to adhere to IO treatments (OR = 0.52, 95% CI = 0.32-0.83, P = 0.006). CONCLUSION: Patients' ethno-national origin and immigration status (primary language, Arabic and Russian), male gender and older age were associated with lower rates of referral to and attendance of the IP consultation, with reduced adherence to weekly IO treatments. These findings require further study to identify barriers toward diversity, equity and inclusion in IO care, increasing awareness among healthcare professionals regarding the benefits of these services for improving patient wellbeing.

BACKGROUND: The risk of gout amid patients with acne keloidalis nuchae (AKN) has not been investigated in the past. OBJECTIVE: To assess the risk of developing gout among patients with AKN relative to control subjects. METHODS: A population-based retrospective study followed patients with AKN (n = 2677) and age-, sex-, and ethnicity-matched control subjects (n = 13 190). The incidence of new-onset gout was compared between the two groups. Hazard ratio (HR) for the risk of gout was obtained using a multivariate Cox regression model. RESULTS: The incidence rate of gout was 1.12 (95% CI, 0.68-1.76) and 0.48 (95% CI, 0.34-0.66) per 1000 person-years among patients with AKN and controls, respectively. The crude risk of developing gout was significantly higher in patients with AKN (HR, 2.27; 95% CI, 1.26-4.10; p = 0.007). After controlling for age, sex, and ethnicity, AKN emerged as an independent risk factor of gout (adjusted HR, 2.34; 95% CI, 1.29-4.22; p = 0.005). When adjusting for other confounders such as body mass index, diabetes mellitus, hypertension, and dyslipidemia, the risk of gout in AKN fell out of significance (adjusted HR, 1.39; 95% CI, 0.73-2.65; p = 0.311), CONCLUSION: Patients with AKN experience an increased risk of gout. The risk is not independent and is mainly mediated through the metabolic comorbidities typifying AKN. We recommend screening for gout in patients with suggestive complaints.

The association of hidradenitis suppurativa (HS) and asthma remains to be investigated. To assess the bidirectional association between HS and asthma. A population-based study was conducted to compare HS patients (n = 6779) with age-, sex-, and ethnicity-matched control subjects (n = 33,259) with regard to the incidence of new onset and the prevalence of preexisting asthma. Adjusted hazard ratios (HRs) and adjusted odds ratios (ORs) were calculated. The prevalence of preexisting asthma was higher in patients with HS relative to controls (9.6% vs. 6.9%, respectively; P < 0.001). The odds of HS were 1.4-fold greater in patients with a history of asthma (fully adjusted OR 1.41; 95% CI 1.27-1.55; P < 0.001). The incidence rate of new-onset asthma was estimated at 9.0 (95% CI 6.3-12.7) and 6.2 (95% CI 5.1-7.5) cases per 10,000 person-years among patients with HS and controls, respectively. The risk of asthma was not statistically different in patients with HS and controls (fully adjusted HR 1.53; 95% CI 0.98-2.38; P = 0.062). Relative to other patients with HS, those with HS and comorbid asthma were younger at the onset of HS (30.7 [14.7] vs. 33.3 [15.1], respectively; P < 0.001) and had a comparable risk of all-cause mortality (adjusted HR 0.86; 95% CI 0.44-1.68; P = 0.660). A history of asthma confers susceptibility to subsequent development of HS. This observation is of importance for clinicians managing both patients with HS and asthma. Further research is warranted to elucidate the pathomechanism underlying this finding.

OBJECTIVE: To compare the incidence of regression in first and second primary melanomas as a possible indication of an 'immunization effect'. METHODS: The first and second primary melanomas of 18 patients were studied histopathologically for signs of regression. At least 1 month elapsed between the removal of the two primary lesions. RESULTS: Histopathological evidence of regression was found in 7 of the 18 (38.8%) first melanomas and in 8 of the 18 (44.4%) second melanomas [p = non-significant (N.S.)]. Among the nine patients in whom the removal of the second primary melanoma was >6 months after the removal of the first primary melanoma, one (11%) first melanoma and three (33%) second melanomas showed regression, respectively, but this difference did not reach statistical significance. Among the nine patients in whom the removal of the second primary melanoma was ≤ 6 months after the removal of the first primary melanoma, six (67%) first melanoma and five (56%) second melanomas showed regression (p = N.S.). CONCLUSIONS: Our study does not provide evidence for a statistically significant increased rate of regression in second primary melanomas compared to the first primary melanomas, but larger groups of studied cases may be needed.

BACKGROUND: Atopic dermatitis or atopic eczema is an itchy inflammatory skin condition with a predilection of the skin flexures. Most cases start in children although some have been reported in adults. Patients with moderate to severe disease refractory to topical corticosteroid or calcineurin inhibitors may require second-line treatment such as phototherapy or systemic immunosuppressants. Methotrexate therapy has been suggested as a useful immunosuppressant in adult atopic dermatitis. OBJECTIVES: To further determine the efficacy of low dose methotrexate therapy in adults with new-onset atopic dermatitis or with idiopathic eczema. METHODS: All adult patients with new-onset atopic dermatitis or idiopathic eczema treated by methotrexate in our clinics from 2004 to 2006 were included in the study. All had failed prolonged therapy with oral antihistamines and local corticosteroid creams. Methotrexate, 10-20 mg, was given orally once a week along with folic acid supplements 5 days a week. Additional therapies included predominantly emollients. During the entire treatment period the investigators made global assessments of the clinical response. RESULTS: Nine patients diagnosed with late-onset atopic dermatitis (n = 6) or idiopathic eczema (n = 3) were treated with methotrexate. All patients responded to the drug. The initial response was noted after 3-7 weeks. Six patients achieved complete remission after 3 months of methotrexate therapy and three patients had significant improvement. One patient's condition worsened after achieving a complete response while on methotrexate and the drug was withdrawn completely. No serious adverse events were noted during treatment. CONCLUSIONS: Low dose methotrexate is an effective therapeutic alternative for late-onset atopic dermatitis or idiopathic eczema in patients unresponsive to local and other systemic therapies.

OBJECTIVE: Previous research on diagnosis of distress among patients with physical ailments has focused on physicians who specialize in the treatment of chronic illness. This study explores family physicians' accuracy in diagnosing patients' emotional distress. METHODS: Questionnaires were administered to family physicians (N=61) and their patients (N=496) immediately after a medical encounter. Patients reported their distress levels. Physicians evaluated patients' distress levels and filled out a questionnaire measuring perspective-taking, i.e., the tendency to perceive the point of view of others. RESULTS: Mixed model analyses of nested data showed a moderate positive relationship between physicians' evaluations of patients' distress and patients' self-reported distress. Diagnosis of distress was more accurate among family physicians with a better ability to take the patient's perspective. CONCLUSION: Family physicians' capacity to accurately diagnose patient distress is positively related to their ability to adopt patients' viewpoint. PRACTICE IMPLICATIONS: Family physicians' training should include enhancement of physicians' ability to take the patient's perspective.
RESUMO
Pemphigus vulgaris (PV) is a severe autoimmune blistering disease caused by anti-epithelial antibodies, leading to disruption of cell-cell adhesion. Although the disease is exceedingly rare worldwide, it is known to be relatively prevalent in Jewish populations. The low prevalence of the disease represents a significant obstacle to a genome-wide approach to the mapping of susceptibility genes. We reasoned that the study of a genetically homogeneous cohort characterized by a high prevalence of PV may help exposing associated signals while reducing spurious results due to population sub-structure. We performed a genome-wide association study using 300K single-nucleotide polymorphisms (SNPs) in a case-control study of 100 PV patients of Jewish descent and 397 matched control individuals, followed by replication of significantly associated SNPs in three additional cohorts of Jewish, Egyptian, and German origin. In addition to the major histocompatibility complex locus, a genomic segment on 8q11.23 that spans the ST18 gene was also found to be significantly associated with PV. This association was confirmed in the Jewish and Egyptian replication sets but not in the German sample, suggesting that ST18-associated variants may predispose to PV in a population-specific manner. ST18 regulates apoptosis and inflammation, two processes of direct relevance to the pathogenesis of PV. Further supporting the relevance of ST18 to PV, we found this gene to be overexpressed in the skin of PV patients as compared with healthy individuals.

This study presents a 10-year survey of 2285 patients tested to common preservatives in northern Israel. The demographic and clinical data were analysed using a revised MOAHLFA index. Patch testing was based on the International Contact Dermatitis Research Group (ICDRG) guidelines. 411 (18%) patients were found to have positive reactions to 1 or more preservatives. The most frequent allergens tested positively were thimerosal, methylchloroisothiazolinone/methylisothiazolinone (MCI/MI), and formaldehyde. The reactions to MCI/MI remained stable around 1.7% throughout the years 1995-1998, with a significant increase to 3.7%-4% (P = 0.029) during 1999-2004. The reactions to formaldehyde remained low around 0.3% until 1999; however, a considerable increase throughout the years 2000-2004 was noted, with rates of 1.5%-1.9% (P = 0.028). The sensitivity rates for parabens, quaternium-15, imidazolidinylurea, and diazolidinylurea were low and unchanged, mostly under 0.5%. As for methyldibromoglutaronitrile (MDBGN), sensitivity rates around 2% were detected for the years 1996 and throughout 2000-2004. Overall, this extensive survey showed a concerning increase in the sensitivity rates for MCI/MI, formaldehyde, and MDBGN.
