Abstract
The authors evaluated the efficacy of interferon-alpha used intralesionally in the therapy of low-grade conjunctival non-Hodgkin lymphoma in an HIV-positive patient. The patient received one intralesional injection of 1,000,000 U of interferon-alpha three times a week for a total of twelve doses. The remission of conjunctival involvement was seen three months from the end of therapy. The intralesional use of interferon-alpha can be considered an efficacious therapy for low-grade conjunctival non-Hodgkin lymphoma.

Abstract
Toll-like receptor (TLR)7/8 plays a crucial role in host recognition/response to viruses and its mucosal expression directly correlates with intestinal inflammation. The aim of this study was to investigate the role of TLR7/8 stimulation of intestinal epithelium in shaping the phenotype and functions of innate immunity cell subsets, and to define direct and/or epithelial cell-mediated mechanisms of the TLR7/8 agonist R848 immunomodulatory activity. We describe novel, TLR8-mediated, pro- and anti-inflammatory effects of R848 on ex vivo cultured human blood monocytes and γδ T lymphocytes, either induced by direct immune cell stimulation or mediated by intestinal epithelial cells (IEC). Apical stimulation with R848 led to its transport across normal polarized epithelial cell monolayer and resulted in the inhibition of monocyte differentiation toward immunostimulatory dendritic cells and Th1 type response. Furthermore, γδ T lymphocyte activation was promoted following direct exposure of these cells to the agonist. Conversely, a selective enrichment of the CD14+CD16+ monocyte subpopulation was observed, which required a CCL2-mediated inflammatory response of normal epithelial cells to R848. Of note, a TLR-mediated activation of control γδ T lymphocytes was promoted by inflamed intestinal epithelium from active Crohn's disease patients. This study unravels a novel regulatory mechanism linking the activation of the TLR8 pathway in IEC to the monocyte-mediated inflammatory response, and highlights the capacity of the TLR7/8 agonist R848 to directly enhance the activation of γδ T lymphocytes. Overall these results expand the range of cell targets and immune responses controlled by TLR8 triggering that may contribute to the antiviral response, to chronic inflammation, as well as to the adjuvant activity of TLR8 agonists, highlighting the role of intestinal epithelium microenvironment in shaping TLR agonist-induced responses.

Abstract
One possible explanation for the failure of human immunodeficiency virus type 1 (HIV-1) antiretroviral inhibitors to block the clinical progression of the infection may be a failure to maintain adequate drug levels at the site of viral replication. We have previously found that exposure of human monoblastoid cells (U937) for several months to a therapeutically relevant concentration (0.1 μM) of 2′,3′-dideoxycytidine (zalcitabine, ddC) allowed the isolation of a drug-resistant cell line characterized by a normal drug transport but a reduced ability to accumulate 2′,3′-dideoxycytidine 5′-triphosphate (the active antiretroviral form of the drug). In this paper we show that the drug-resistant cells were indistinguishable from normal cells in terms of surface CD4 receptors. The susceptibility of parental and ddC-resistant U937 cells to infection by HIV-1 was similar, as measured by proviral DNA formation. However, HIV-1 p24 production and the number of infectious virus particles produced were significantly lower in the drug-resistant compared to control cells. Addition of 0.1 μM ddC inhibited viral production by up to 92% in the control cells but had no effect on ddC-resistant cells. Thus, human cells exposed to therapeutically relevant ddC concentrations for several months show a reduced ddC anabolism and allow ddC-sensitive HIV-1 to replicate in the presence of inhibitory ddC concentrations.

Abstract
Lactoferrin (LF), an iron-binding glycoprotein expressed in most biological fluids, represents a major component of mammalian innate immune system. The multiple activities of LF rely not only on its capacity to bind iron but also to interact with molecular and cellular components of both the host and pathogens. LF can bind and sequester lipopolysaccharide thus preventing proinflammatory pathway activation, sepsis, and tissue damage. However, the interplay between LF and lipopolysaccharide is complex and may lead to different outcomes including both the suppression of inflammatory response and immune activation. Understanding the molecular basis and the functional consequences of this complex interaction is critically relevant in the development of LF-based therapeutic interventions in humans.

Abstract
Lactoferrin (LF), a key element in mammalian immune system, plays pivotal roles in host defence against infection and excessive inflammation. Its protective effects range from direct antimicrobial activities against a large panel of microbes, including bacteria, viruses, fungi and parasites, to antinflammatory and anticancer activities. In this study, we show that monocyte-derived dendritic cells (MD-DCs) generated in the presence of bovine LF (bLF) fail to undergo activation by up-modulating CD83, co-stimulatory and major histocompatibility complex molecules, and cytokine/chemokine secretion. Moreover, these cells are weak activators of T cell proliferation and retain antigen uptake activity. Consistent with an impaired maturation, bLF-MD-DC primed T lymphocytes exhibit a functional unresponsiveness characterized by reduced expression of CD154 and impaired expression of IFN-γ and IL-2. The observed imunosuppressive effects correlate with an increased expression of molecules with negative regulatory functions (i.e. immunoglobulin-like transcript 3 and programmed death ligand 1), indoleamine 2,3-dioxygenase, and suppressor of cytokine signaling-3. Interestingly, bLF-MD-DCs produce IL-6 and exhibit constitutive signal transducer and activator of transcription 3 activation. Conversely, bLF exposure of already differentiated MD-DCs completely fails to induce IL-6, and partially inhibits Toll-like receptor (TLR) agonist-induced activation. Cell-specific differences in bLF internalization likely account for the distinct response elicited by bLF in monocytes versus immature DCs, providing a mechanistic base for its multiple effects. These results indicate that bLF exerts a potent anti-inflammatory activity by skewing monocyte differentiation into DCs with impaired capacity to undergo activation and to promote Th1 responses. Overall, these bLF-mediated effects may represent a strategy to block excessive DC activation upon TLR-induced inflammation, adding further evidence for a critical role of bLF in directing host immune function.

Abstract
Nonspecific lipid transfer proteins (nsLTPs) are members of the prolamine superfamily and they are found in pollen and food, as well as in latex. Due to the strong stability both against pepsin digestion and thermal denaturation, sensitisation towards these proteins is often associated with severe systemic reactions (angioedema, urticaria, asthma, anaphylaxis, etc.) following the ingestion of both raw or fresh food and cooked or preserved food. Many studies have shown reactivity towards nsLTPs both via inhalation and orally and in this study we present two cases of nsLTPs-sensitive patients who manifested the immediate onset of skin reactions following the use of cosmetic products containing these proteins. Thus, in order to prevent immediate reactions linked to their use, it is necessary to recommend nsLTPssensitive patients to avoid the topical use of products containing these proteins (and obviously the ingestion of foods containing these proteins).

Abstract
Lactoferrin (Lf) is a mammalian exclusive protein widely distributed in milk and exocrine secretions exhibiting multifunctional properties. Many of the proven or proposed functions of Lf, apart from its iron binding activity, depend on its capacity to bind to other macromolecules. Lf can bind and sequester lipopolysaccharide (LPS), thus preventing pro-inflammatory pathway activation, sepsis and tissue damage. However, the interplay between Lf and LPS is complex, and may result in different outcomes, including both suppression of the inflammatory response and immune activation. These findings are critically relevant in the development of Lf-based therapeutic interventions in humans. Understanding the molecular basis and functional consequences of Lf-LPS interaction will provide insights for determining its role in health and disease.

Lf’s multiple activities rely not only on its capacity to bind iron, but also to interact with molecular and cellular components of both host and pathogens. Lf can bind and sequester lipopolysaccharide (LPS), thus preventing pro-inflammatory pathway activation, sepsis and tissue damage. However, Lf-bound LPS may retain the capacity to induce cell activation via Toll-like receptor 4-dependent and -independent mechanisms. This review discusses the complex interplay between Lf and LPS and its relevance in the regulation of the immune response.

23 newly diagnosed patients affected by cutaneous T-cell lymphoma were treated with sub-cutaneous interferon alpha-2a to evaluate the therapeutic efficacy and the toxicity of this agent. IFN was administered daily with dose escalation from 3 to 18 million units for 12 weeks; thereafter, patients induced into complete (CR) or partial (PR) remission were given IFN at maximal tolerated dose 3 times weekly for 6 or 9 months. The objective tumor response was observed in 17 patients (74%): 8 (35%) were CR and 9 (39%) were PR. A 74-yr-old patient died because of neutropenia and sepsis at the end of induction phase, while receiving IFN at dose of 18 million units. Disease stage is the initial feature predictive of response to IFN therapy. The dose schedule of this study was well tolerated: only 3 patients developed liver toxicity, while leukopenia was evident in 6 patients. Only 2 CR patients have relapsed, 18 and 24 months from response; the remaining 6 CR patients are in continuous complete remission with a median follow-up of 41.8 months. 6 PR patients have progressed from 8 to 17 months after response, and in the 3 PR patients not yet progressed the response duration ranges from 20 to 24 months. In conclusion, interferon alpha-2a is a very effective agent in therapy of untreated cutaneous T-cell lymphoma with an overall response rate of 74%.

Abstract
Myeloid dendritic cells (DC) and macrophages evolve from a common precursor. However, factors controlling monocyte differentiation toward DC or macrophages are poorly defined. We report that the surface density of the GM-CSF receptor (GM-CSFR) alpha subunit in human peripheral blood monocytes varies among donors. Although no correlation was found between the extent of GM-CSFR and monocyte differentiation into DC driven by GM-CSF and IL-4, GM-CSFR expression strongly influenced the generation of CD1a(+) dendritic-like cells in the absence of IL-4. CD1a(+) cells generated in the presence of GM-CSF express CD40, CD80, MHC class I and II, DC-SIGN, MR, CCR5, and partially retain CD14 expression. Interestingly, they spontaneously induce the expansion of CD4(+) and CD8(+) allogeneic T lymphocytes producing IFN-gamma, and migrate toward CCL4 and CCL19. Upon stimulation with TLR ligands, they acquire the phenotypic features of mature DC. In contrast, the allostimulatory capacity is not further increased upon LPS activation. However, by blocking LPS-induced IL-10, a higher T cell proliferative response and IL-12 production were observed. Interestingly, IL-23 secretion was not affected by endogenous IL-10. These results highlight the importance of GM-CSFR expression in monocytes for cytokine-induced DC generation and point to GM-CSF as a direct player in the generation of functionally distinct DC.

Abstract
Lactoferrin (Lf) plays an important role in host defense against infection and excessive inflammation. Although the mechanisms underlying its immunomodulatory properties have not been fully elucidated yet, recent evidence suggests that some of these effects may be related to its capacity to form complexes with LPS. We report that the culture of resting mouse peritoneal macrophages (PM) with bovine Lf (bLf), prior to infection with the vesicular stomatitis virus (VSV), resulted in a significant reduction of virus yield with respect to control cultures. The antiviral activity of bLF was related to its capacity of inducing IFN-alpha/beta expression, which in turn inhibited VSV replication. Indeed, the accumulation of IFN-beta but not of IFNalpha(1-2) transcripts was up-modulated markedly early after bLf addition. Furthermore, bLf did not exert any antiviral activity in the presence of neutralizing antibodies to IFN-alpha/beta in PM from wild-type mice, as well as in PM from mice genetically defective for the response to IFN. The antiviral activity of bLf relied on its intrinsic capacity to bind LPS, as this protein did not induce IFN expression in PM from LPS-hyporesponsive mice. It is interesting that this LPS-binding property was dispensable for the production of TNF-alpha, which also occurred in LPS-hyporesponsive mice. Overall, these results indicate that some of the immunomodulatory effects ascribed to Lf may be related to its capacity to favor Type I IFN expression and argue in favor of an important role of the LPS-binding feature and TLR4 in some of the effects ascribed to this molecule.

Abstract
OBJECTIVES To evaluate the effect of patient satisfaction on health-related quality of life among dermatological outpatients, independently of patients' sociodemographic, and clinical characteristics. DESIGN Prospective cohort study. Satisfaction was evaluated with a standardized questionnaire three days after the visit by telephone interview. Quality of life and psychiatric disorders were measured with validated instruments (Skindex-29 and Ghq-12) before the dermatological visit and after four weeks. At the four week interview also self-reported medication adherence was assessed. SETTING Outpatient clinics of a large dermatological hospital in Rome, Italy. PATIENTS A consecutive sample of 1389 outpatients was approached, and 52% agreed to participate. Inclusion criteria were met by 424 patients, and 396 (93%) of them completed the study. MAIN OUTCOME MEASURES Improvement in health related quality of life. RESULTS At multivariate analysis satisfied patients have approximately twice the odds for an improved quality of life on the emotions scale (OR = 1.99; 95%CI 1.1 to 3.7; P = 0.03) and on the functioning scale (OR = 2.2; 95%CI 1.1 to 4.7; P = 0.03). Patients with psychiatric disorders at baseline were less likely to have an improved quality of life on the functioning scale (OR = 0.3; 95%CI 0.2 to 0.8; P = 0.01). CONCLUSIONS This is the first prospective study showing that patient satisfaction and psychiatric disorders have a significant effect on quality of life improvement among dermatological patients, independently of patient characteristics. Particular attention should be devoted to improving physicians' interpersonal skills, the major component of patient satisfaction.

Abstract
The job satisfaction and psychological well-being of health care workers may significantly influence the quality of care they provide. The aim of this study was to assess burnout and psychiatric disorders, such as anxiety and depression, as well as evaluate job satisfaction among nurses working at the IDI-Sanità in Rome. Nurses (n = 545) were invited to answer an anonymous, self-administered questionnaire, which consisted of the Maslach Burnout Inventory (MBI), the General Health Questionnaire (GHQ-12), and a validated questionnaire to examine job satisfaction. Descriptive analyses and multiple logistic regression analysis were performed. The section designed to evaluate job satisfaction was specifically examined by means of principal component factor analysis. Two hundred and forty-two nurses answered the questionnaire (response rate: 44%). Emotional exhaustion was observed in 38% of respondents. No significant difference was detected between mean values ( standard deviation) at each of the three MBI subscales and Italian normative data. About 33% of respondents showed a GHQ-12 score typical for disorders such as anxiety or depression. High levels of job satisfaction were found to be associated to a lower likelihood both of emotional exhaustion at MBI and psychiatric morbidity at GHQ-12. Factor analysis on items investigating job satisfaction identified 4 factors that globally accounted for 61% of the total variance. The factors obtained could represent possible targets for action aimed at improving nurse satisfaction.

Abstract
The "Euro-Lupus Cohort" is composed by 1000 patients with systemic lupus erythematosus (SLE) that have been followed prospectively since 1991. These patients have been gathered by a European consortium--the "Euro-Lupus Project Group". This consortium was originated as part of the network promoted by the "European Working Party on SLE", a working group created in 1990 in order to promote research in Europe on the different problems related to this disease. The "Euro-Lupus Cohort" provides an updated information on the SLE morbidity and mortality characteristics in the present decade as well as defines several clinical and immunological prognostic factors.

Abstract
We investigated the effect of interleukin (IL)-2, a T cell growth factor capable of activating certain macrophage functions, on interferon (IFN)-gamma expression in resting mouse peritoneal macrophages (PM). IL-2 addition to PM from different mouse strains up-modulated IFN-gamma mRNA and protein secretion. It is notable that endogenous type I and II IFNs did not play any role in the IL-2-mediated effect, as comparable levels of secreted IFN-gamma were observed upon IL-2 stimulation of PM from deficient mice. In contrast, endogenous IFN-gamma was requested for the IL-12-induced IFN-gamma production. It is interesting that blocking of each component of the IL-2 receptor (IL-2R) by neutralizing antibodies almost completely abolished IL-2-induced IFN-gamma production, suggesting that all IL-2R chains contribute to the PM biological response to IL-2. The simultaneous treatment of PM with IL-2 and IL-12 resulted in a higher IFN-gamma secretion with respect to that obtained upon treatment with IL-2 or IL-12 alone. It is notable that IFN-gamma protein was expressed intracellularly in the majority of cells exhibiting a macrophage phenotype (i.e., F4/80+) and was secreted upon IL-2 stimulation. Overall, these findings demonstrate that IL-2 regulates at different levels IFN-gamma expression in macrophages, highlighting the crucial role of these cells and their regulated responsiveness to key cytokines in the cross-talk between innate and adaptive immunity.

Abstract
We studied the expression of adhesion molecules affecting recirculation and homing on peripheral blood CD4(+) T cells of patients with systemic sclerosis (SSc), in order to evaluate whether the distribution of tissue targeted subsets could reflect the participation of internal organs or the extent of cutaneous involvement [i.e. limited cutaneous (lc) and diffuse cutaneous (dc)]. Peripheral blood mononuclear cells (PBMC) from 51 patients with SSc and 19 sex- and age-matched controls were investigated by cytofluorimetric analysis for lymphocyte subpopulations carrying the following surface molecules: CD3, CD4, CLA, alpha4beta7 and alpha4beta1. Standard routine biochemistry and clinical examinations were also performed in all patients. We found that both alpha4beta1(+) and alpha4beta7(+) cells within the CD4(+) T cell population were significantly increased, while CLA(+) CD4(+) T cells were significantly reduced in SSc, compared to healthy donors. Significantly lower absolute numbers of alpha4beta7(+) cells were found in lc- compared to dc-SSc. Patients with oesophageal involvement had high numbers of alpha4beta7(+) cells, while those with nephritis also showed low levels of CLA(+) cells. Lung involvement was related directly to alpha4beta1(+) cell numbers and inversely to alpha4beta7(+) CD4 cell numbers. Taken together, our findings demonstrate that distinct CD4(+) T cell populations with selective homing properties show changes from normal distribution in SSc, and such changes are related to clinical expression and organ involvement in the course of the disease.

Abstract
Atherosclerosis (ATS) is a multifactorial disease caused by the interaction of established or emerging risk factors with multiple predisposing genes that regulate ATS-related processes. This review will discuss the current knowledge concerning the potential role of the genetic variations that could promote and/or accelerate ATS, in both animal models and humans. Allelic polymorphisms or variations of distinct genes that enhance the risk of ATS frequently occur in the general population, but only adequate gene-environment interactions will lead to the disease. The main genes so far studied are involved in the regulation of processes such as endothelial function, antioxidant potential, coagulation, inflammatory response, and lipid, protein and carbohydrate metabolism. The detection of candidate genes associated with ATS could allow, in the near future, earlier interventions in genetically susceptible individuals. Further, large-scale population studies are needed to obtain more information on the specific gene-environment and drug-gene interactions capable of influencing ATS progression.

Abstract
Systemic sclerosis (SSc) is a connective tissue disorder characterized by excessive collagen deposition in the skin and internal organs. Several cytokines and chemokines have been implicated in the induction of fibrosis, but a definitive relationship between specific cytokines and organ involvement has not been established yet. Serum samples, PBMC and T cell lines (TCL) obtained from 54 patients affected by SSc and 20 healthy donors (HD) were examined by ELISA for Interferon-gamma (IFN-gamma ), interleukin (IL)-4, IL-6, IL-10, IL-18, Transforming growth factor (TGF)-beta1, Tumour necrosis factor (TNF)-alpha, sCD30, Macrophage derived chemokine (MDC), Monocyte chemoattractant protein (MCP)-1, Macrophage inflammatory protein (MIP)-1alpha and Regulated on activation normal T-cell expressed and secreted (RANTES). In all the SSc serum samples, we found significantly increased levels of IL6, TNFalpha and MCP-1 but reduced amounts of gamma-IFN and MDC. IL6, IL10, IL18, MIP-1alpha and TNFalpha measured in supernatants from PHA-stimulated PBMC and IL6, MCP-1 and RANTES in supernatants from stimulated TCL were also increased in patients. MDC was decreased in all the biological SSc sources studied. TGF-beta1, IL10, and sCD30 were produced at a significantly lower level by SSc TCL. Serum IL6 and sCD30 levels were significantly increased in dc-SSc patients compared to lc-SSc as were levels of MCP-1 produced by PBMC and IL10 from TCL. We observed a strict relationship between pulmonary fibrosis and IL10, MCP-1 (both from TCL) and serum IL6. Kidney involvement was related to serum MCP-1 levels and IL18 production from PBMC. Oesophageal involvement correlated with MDC production from PBMC and IL10 synthesis by TCL. We showed that IL-6, IL-10, MDC and MCP-1 are variably associated with internal organ involvement and allow the discrimination between limited and diffuse forms of the disease.

Abstract
BACKGROUND Psychological distress among healthcare professionals can have negative effects on the well-being of the professionals and also on the quality of care they provide to patients. OBJECTIVES To evaluate burnout and job satisfaction of dermatologists and nurses working with dermatological patients compared with physicians and nurses of other specialties. METHODS A self-completed anonymous questionnaire was distributed to the personnel of two hospitals in Rome, Italy: a dermatological hospital (IDI) and a general hospital (GH), belonging to the same non-profit organization. Standardized instruments were used to assess burnout (Maslach Burnout Inventory) and job satisfaction. Multiple logistic regression was used to examine the association between burnout and working in dermatology vs. other specialties, job satisfaction, years of employment and respondents' sex and age. RESULTS We distributed 929 questionnaires to clinical and non-clinical staff of IDI and 494 questionnaires to the GH staff (response rates: 53% at IDI and 50% at the GH). Among respondents there were 67 physicians and 59 nurses at IDI and 70 physicians and 148 nurses at the GH. Subsequent analyses refer only to this clinical subsample. Factor analysis showed that among physicians and nurses the two main factors explaining job satisfaction were respondents 'satisfaction with the management of their unit' and 'opportunities for personal growth'. Among nurses the likelihood of burnout decreased significantly with higher levels of job satisfaction [odds ratio (OR) = 0.78; 95% confidence interval (95% CI) 0.7-0.9] and working in dermatology compared with other specialties (OR = 0.46; 95% CI 0.2-0.9). Among physicians a lower likelihood of burnout was associated with job satisfaction (OR = 0.66; 95% CI 0.5-0.8) and older age (OR = 0.28; 95% CI 0.1-0.8). CONCLUSIONS Among both physicians and nurses, job satisfaction was associated with a lower likelihood of burnout, independently of clinical specialty and other factors. Burnout was similar for dermatologists and other specialists. Nurses of the GH compared with those working in dermatology had a higher probability of burnout and were significantly less satisfied with the management of their units and with opportunities for personal growth.

Abstract
Cutaneous infiltration of activated CD4(+) T cells and eosinophils is an early event in blister formation during bullous pemphigoid (BP), suggesting that the trafficking of circulating leucocytes through the sites of inflammation, their activation and cytokine release is crucial in the pathogenesis of the disease. IL-16 is a major chemotactic factor able to recruit CD4(+) cells in the skin during inflammation and to induce the expression of functional high-affinity interleukin (IL)-2 receptors, thus contributing to cellular activation and proliferation. We performed a study in order to evaluate the presence of IL-16 in skin samples and sera and blister fluids of patients affected with BP in active phase of the disease (n = 39), compared with healthy donors studied as control group. Ten patients were also evaluated before and after steroid therapy. Our results demonstrated that IL-16 was expressed strongly by keratinocytes and by dermal infiltrating CD4(+) T lymphocytes in lesional skin of BP patients. High levels of IL-16 were detected in sera and blisters of BP, significantly higher in respect to healthy donors. When patients were investigated for the presence of eosinophil cationic protein (ECP) and soluble CD30 (sCD30) to reveal signs of eosinophils and Th2-cells activation, we found a positive correlation between IL-16 serum levels and both ECP and sCD30, suggesting that IL-16 is involved in Th2 lymphocytes and eosinophils recruitment during BP.

Abstract
BACKGROUND Amelanotic malignant melanoma is a subtype of cutaneous melanoma with little or no pigment on visual inspection. It may mimic benign and malignant variants of both melanocytic and nonmelanocytic lesions. OBJECTIVES To evaluate whether dermoscopy is also a useful technique for the diagnosis of amelanotic/hypomelanotic melanoma (AHM). METHODS We conducted a retrospective clinical study of 151 amelanotic/hypomelanotic skin lesions from 151 patients with a mean age of 47 years (+/- 17.5 SD). Digitized images of amelanotic/hypomelanotic skin lesions were converted to JPEG format and sent by e-mail from the five participating centres. Lesions included 55 amelanotic/hypomelanotic nonmelanocytic lesions (AHNML), 52 amelanotic/hypomelanotic benign melanocytic lesions (AHBML), and 44 AHM, 10 (23%) of which were nonpigmented, truly amelanotic melanomas (AM). The 44 AHM lesions were divided into thin melanomas (TnM) </= 1 mm (29 cases) and thick melanomas (TkM) > 1 mm (15 cases), according to the Breslow index. Five clinical features (elevation, ulceration, shape, borders and colour) as well as 10 dermoscopic criteria (pigment network, pigmentation, streaks, dots/globules, blue-whitish veil, regression structures, hypopigmentation, leaf-like areas, multiple grey-bluish globules, central white patch) and eight vascular patterns (comma, arborizing, hairpin, dotted, linear irregular, dotted and linear irregular vessels, and milky-red areas) were evaluated in order to achieve clinical and dermoscopic diagnoses. Statistical analyses were performed with the chi2-test and Fisher's exact test, when appropriate. RESULTS The most frequent and significant clinical features for TnM and TkM were asymmetry and ulceration (the latter only for TkM) compared with AHBML. Irregular dots/globules (62% vs. 35%; P </= 0.03), regression structures (48% vs. 27%; P </= 0.03), irregular pigmentation (41% vs. 11%; P </= 0.03) and blue-whitish veil (10% vs. 0%; P </= 0.03) were the most relevant dermoscopic criteria for TnM in comparison with AHBML. TkM differed significantly from AHBML in frequency of occurrence of irregular pigmentation (87% vs. 11%; P </= 0.03), irregular dots/globules (73% vs. 35%; P </= 0.03), regression structures (67% vs. 27%; P </= 0.03), blue-whitish veil (27% vs. 0%; P </= 0.03) and hypopigmentation (13% vs. 55%; P </= 0.03). Linear irregular vessels and the combination of dotted and linear irregular vessels associated with TnM and TkM were not found in our cases of AHBML and were only rarely seen in AHNML (3.6% and 1.8%, respectively). Moreover, TkM differed significantly from AHBML and TnM in frequency of occurrence of milky-red areas (93% vs. 17%; P </= 0.03 and 93% vs. 31%; P </= 0.01, respectively). The dermoscopic diagnosis of melanoma had a higher sensitivity and specificity than the clinical diagnosis (89% and 96% vs. 65% and 88%, respectively). With the limitation of the small number of cases, vascular patterns were the only dermoscopic criteria for 'truly' AM. In the 10 cases of 'truly' AM, we found milky-red areas in more than half of the cases (six of 10), dotted vessels in four, hairpin vessels in two, linear irregular vessels in two, dotted and linear irregular vessels in two. CONCLUSIONS Because dermoscopy uses criteria reflecting pigmentation (irregular pigmentation and irregular dots/globules) and vascular patterns, it is a useful technique not only for pigmented melanoma but also for hypomelanotic melanoma. In 'truly' AM, vascular patterns alone may not be sufficient to diagnose melanoma. A combined approach with the clinical information should help in the detection of 'truly' AM.

Abstract
In this study we examined two unrelated patients affected with the lethal variant of junctional epidermolysis bullosa with pyloric atresia (PA-JEB) who were found to carry mutations in the integrin beta4 subunit gene (ITGB4). Although in both patients Northern blot analysis showed only a 50% reduction in the level of ITGB4 transcript, a complete lack (patient 1) or a strong reduction (patient 2) of beta4 immunoreactivity was observed in the skin. Using immunoprecipitation analysis, integrin beta4 could not be visualized in patient 1 cells while a markedly reduced amount (approximately 20%) of normal sized beta4 chains was detected in patient 2. These data suggested the presence of ITGB4 mutations that interfere with both mRNA and protein stability. Using molecular analysis, patient 1 was shown to be a compound heterozygous for a single amino acid deletion (deltaN318) and a not yet identified mutation that induces a very rapid decay of the encoded mRNA transcript. Patient 2 was, instead, a compound heterozygous for a novel 4-bp tandem duplication (4298-4299ins4) and a previously described missense mutation (R252C). Our data support the notion that PA-JEB lethal phenotypes associated with a markedly decreased/absent alpha6beta4 expression can be due not only to the presence of null alleles, but also to specific mutations leading to protein instability and/or altered function.

Abstract
OBJECTIVES To test the hypothesis that some acute phase proteins may be better independent predictors of objective measures of arterial wall impairment than traditional risk factors. DESIGN Cross-sectional study. MATERIALS AND METHODS C-reactive protein (CRP), fibrinogen, C3 complement and traditional risk factors were measured in 288 men aged 55-64 years, randomly chosen from the local registry lists. By ultrasound assessment of the bifurcations of carotid and femoral arteries, maximum combined plaque/intima-media thickness (CPIMTmax) and mean plaque density (MPD, in a grey scale from 0 to 255) were also measured. RESULTS In multivariate analysis only traditional risk factors remained associated with the overall CPIMTmax: smoking (r = 0.35, p < 0.0001), cholesterol (r = 0.23, p = 0.0001), age (r = 0.22, p = 0.0002), glucose (r = 0.18, p = 0.002) and systolic blood pressure (r = 0.13, p = 0.02). However, with regard to carotid disease only, fibrinogen was the strongest covariate of CPIMT (r = 0.18, p = 0.002). The overall MPD was independently associated with CRP (r = 0.25, p = 0.0008), physical activity (r = 0.19, p = 0.009), triglycerides (r = -0.18, p = 0.02) and body mass index (r = 0.15, p = 0.04). CRP was mainly associated with femoral MPD, while triglycerides were the major (inverse) covariate of carotid MPD. CONCLUSIONS Traditional risk factors are the main determinants of CPIMTmax, although fibrinogen seems to play a role in carotids. CRP was associated with high density femoral plaques. Finally, no acute phase protein was independently associated with low density, potentially vulnerable, plaques.

Abstract
BACKGROUND Multiple drug allergy syndrome is a clinical condition characterized by reactions against more than one different class of, both pharmacologically and structurally, unrelated drugs. Scanty data are available to date about a multiple drug delayed hypersensitivity syndrome. Our aim was to report the case of a delayed reaction to both beta-methasone (beta-MT) and penicillin-G (pen-G) occurring in the same patient, and analyse beta-MT- and pen-G-specific T-cell Lines (TCLs) with regard to their specificity, phenotype and cytokine profile. METHODS We generated two drug-specific TCLs from biopsies at the site of positive intradermal reactions, and analysed their immunophenotype, T-cell receptor Vbeta (TCR-Vbeta) domains expression and cytokine profile. RESULTS We demonstrated the specificity of the T cells isolated from positive intradermal test reactions to pen-G and beta-MT through the strict dose-dependent proliferation in response to drug-pulsed autologous antigen presenting cells. Fluorescence activated cell sorter (FACS) analysis revealed a predominance of CD4+ cells in the inflammatory cell infiltrate of intradermal test with beta-MT, while a predominance of CD8+ T cells in the site of delayed reaction to pen-G was found. The drug specific CD4+ and CD8+ T cells were heterogeneous, with regard to TCR-Vbeta usage. CD8+ pen-G-TCL displayed a preferential T helper 2 (Th2) profile, while a substantially heterogeneous pattern of cytokine production characterized specific beta-MT TCL. CONCLUSION The study describes the coexistence in the same patient of a delayed hypersensitivity to both penicillin G and beta-MT, driven, respectively, by pen-G-specificTh2-skewed CD8+ and beta-MT specificTh0 CD4+ T cells. This case further support the existence of a multiple drug allergy syndrome also for delayed hypersensitivity.

Abstract
Cellulite is the result of complex physiological changes of the subcutaneous fat layer and of microcirculation, clinically manifesting as orange peel skin especially in women and involving thighs, buttocks, and abdomen. An adequate water intake has been suggested to be helpful in controlling the development and worsening of the disease. An open randomized controlled study has been performed to evaluate modification induced by an adequate diet associated to low-sodium or high-sodium water intake on some clinical features of patients affected with mild to moderate cellulite. Non-invasive instrumental investigations (Bioelectrical Impedance Analysis (BIA), thermography and skin echography) were used before and after dietary treatment. A significant improvement of the disease, in terms of weight loss, cutaneous microcirculation and reduction of subcutaneous fat layer, was observed in the group of patients who underwent low-sodium water intake. An adequate dietary treatment associated to a low-sodium water intake is able to efficiently controll some biological and clinical parameters of mild to moderate cellulite.

Abstract
The "Euro-Lupus Cohort" is composed by 1,000 patients with systemic lupus erythematosus (SLE) that have been followed prospectively since 1991. These patients have been gathered by a European consortium - the "Euro-Lupus Project Group". This consortium was originated as part of the network promoted by the "European Working Party on SLE", a working group created in 1990 in order to promote research in Europe on the different problems related to this disease. The "Euro-Lupus Cohort" provides an updated information on the SLE morbidity and mortality characteristics in the present decade as well as defines several clinical and immunological prognostic factors.

Abstract
BACKGROUND The purpose of this paper is to present personal experience with sentinel node biopsy for the treatment of malignant melanoma. Technical details influencing the efficacy of the procedure are presented and the clinical, therapeutic and prognostic advantages of this technique discussed. METHODS A total of 390 consecutive patients with primary skin melanoma (T2-3,N0,M0) underwent sentinel node biopsy between March 1996 and May 2001. All patients underwent previous excisional biopsy of the primary lesion and clinical and radiographic examination to exclude lymphatic or systemic macroscopic spreading of the disease. Preoperative lymphoscintigraphy (99mTc nanocoll) was routinely performed in the last 315 patients. Intraoperative detection of the sentinel nodes was performed by perilesional, intradermical, injection of blue dye associated with a g probe (Neoprobe(R) 2000) in the last 315 patients. Sentinel nodes, serially sectioned, were all Haematoxylin-Eosin and immunohistochemically stained. All patients positive for micro-metastasis underwent radical lymphadenectomy. Comparative analysis between the incidence of metastasis in sentinel and non-sentinel nodes, according to the clinical stage of the disease, was done. RESULTS The overall detection rate of sentinel nodes was 97.4%. Relevant differences were found according to the site of dissection and the use of a g probe. The g-probe makes the procedure more effective, less invasive and less expensive. Timing and accuracy of the preoperative lymphoscintigraphy is a basic step of the procedure. The overall incidence of positive sentinel nodes was 14.7% with differences correlated with thickness of primary lesion (0.75-1.5 mm: 5,8%; 1.5-3 mm:18%; 3-4 mm: 24.6%). Metastasis in other non-sentinel nodes was found only with primary tumour thickness exceeding 2 mm. CONCLUSIONS Sentinel node biopsy is a procedure requiring a multidisciplinary approach (surgery, nuclear medicine and pathology). A specific learning phase (>30 patients) is recommended to obtain reliable results.

Abstract
OBJECTIVE The aim of this study was to investigate the imbalance between Th-1 and Th-2 cytokines in systemic lupus erythematosus patients (SLE) and to asses if any of these cytokines could be related to disease activity. METHODS Twenty SLE patients and 20 healthy individuals were investigated. Blood samples were collected to evaluate, using ELISA method, serum levels of a wide array of cytokines including: Th-1 type cytokines (Interleukin (IL)-12, Interferon (IFN)-gamma), Th-2 cytokines (IL-4, IL-10), pro-inflammatory cytokines (tumor necrosis factor (TNF)-alpha, IL-1beta and IL-18). Disease activity was assessed using the SLE Disease Activity Index (SLEDAI). Data were evaluated using the Mann-Whitney and Spearman's rank tests. RESULTS The SLE patients group had a higher IL-4, IL-10, IL-12 and IL-18 serum concentration compared to the normal control group. IL-18 was negatively correlated with IL-4 and positively correlated with IFN-gamma. No serum cytokine level was correlated with disease activity except for IL-18, which was found strongly correlated with "active disease", defined as SLEDAI > 8 points. IL-18 showed no correlation with pro-inflammatory cytokines. CONCLUSIONS Our results show that Th-1 as well Th-2 cytokines can be elevated in SLE patients suggesting that lupus is a complex disease that may be supported by different cytokine patterns in different time-points. Only IL-18 has been found to be disease-activity related. The role of IL-18 in the pathogenesis of SLE might be important through apoptosis-mediating properties.

Abstract
BACKGROUND Some acute phase proteins are associated with both ischemic events and traditional risk factors. Since they are strongly interrelated, each of them partly reflects the characteristics of other proteins. This study was carried out to ascertain the specific preferential associations of some acute phase proteins with traditional risk factors for atherosclerotic disease. METHODS High-sensitivity C-reactive protein, fibrinogen and C3-complement were assessed in 288 unselected men aged 55-64 years. Three multiple linear regression analyses were performed, in which each of the three acute phase proteins was considered the dependent variable of both traditional risk factors and the other two proteins. RESULTS The three acute phase proteins strongly correlated with each other. Moreover, C-reactive protein was independently associated with triglycerides (P<0.0001), age (P=0.0130), body mass index (P=0.0179), and acute (P=0.0280) and chronic (P=0.0582) inflammations (R2=0.17). Fibrinogen was associated with alcohol consumption (inversely, P=0.0001) and smoking (P=0.0598) (R2=0.06). Finally, C3 was associated with insulin (P<0.0001), cholesterol (P=0.0001), sedentarity (P=0.0028), glucose (P=0.0077), and systolic blood pressure (P=0.0124) (R2=0.28). CONCLUSIONS When simultaneously studied in multivariate analysis, acute phase proteins have different preferential associations with traditional risk factors, a probable consequence of their involvement in different cellular activations and metabolic processes.

Abstract
P-glycoprotein is a 170-kd glycosylated transmembrane protein, expressed in a variety of human cells and belonging to the adenosine triphosphate-binding cassette transporter family, whose membrane expression is functionally associated with the multidrug resistance phenotype. However, the mechanisms underlying the regulation of P-glycoprotein functions remain unclear. On the basis of some evidence suggesting P-glycoprotein-actin cytoskeleton interaction, this study investigated the association of P-glycoprotein with ezrin, radixin, and moesin, a class of proteins that cross-link actin filaments with plasma membrane in a human cell line of lymphoid origin and that have been shown to link other ion-pump-related proteins. To this purpose, a multidrug-resistant variant of CCRF-CEM cells (CEM-VBL100) was used as a model to investigate the following: (1) the cellular localizations of P-glycoprotein and ezrin, radixin, and moesin and their molecular associations; and (2) the effects of ezrin, radixin, and moesin antisense oligonucleotides on multidrug resistance and P-glycoprotein function. The results showed that: (1) P-glycoprotein colocalized and coimmunoprecipitated with ezrin, radixin, and moesin; and (2) treatment with antisense oligonucleotides for ezrin, radixin, and moesin restored drug susceptibility consistently with inhibition of both drug efflux and actin-P-glycoprotein association and induction of cellular redistribution of P-glycoprotein. These data suggest that P-glycoprotein association with the actin cytoskeleton through ezrin, radixin, and moesin is key in conferring to human lymphoid cells a multidrug resistance phenotype. Strategies aimed at inhibiting P-glycoprotein-actin association may be helpful in increasing the efficiency of both antitumor and antiviral therapies.

Abstract
Psychiatric disorders are frequent among patients with skin diseases. We aimed at identifying factors associated with psychiatric morbidity in dermatological outpatients. All adults attending the outpatient clinics of a dermatological hospital on predetermined days were given the 12-item General Health Questionnaire. The dermatologists indicated the diagnosis and location of skin lesions and rated the disease severity. A total of 1389 patients were asked to take part in the study. Of the 722 who accepted, 389 had a complete set of data and were included in the analysis. To verify the representativeness of our sample, we used the administrative registries to compare participants with the total population of patients who attended the clinics during the same period, and we examined the distribution of missing data. There was a tendency towards a younger age in the sample studied, but no evidence of substantial selection bias. The prevalence of psychiatric morbidity was 20.6%. We found higher probability of psychiatric disorders in women, controlling for age, clinical severity and localization of lesions. In women, but not in men, the prevalence of psychiatric morbidity was higher in patients with lesions on the face or hands. Given that the identification and appropriate management of psychiatric morbidity are important, it seems that the dermatologist should be particularly alert to the possibility of a concurrent psychiatric disorder in women with lesions on the face or hands.

Abstract
OBJECTIVE To establish which traditional and conditional risk factors were effectively treated, and which remained active, in patients with previous myocardial infarction (PMI). METHODS AND RESULTS In 47 PMI patients recently submitted to cardiological assessment and in 42 controls (50-70 years old men), traditional risk factors (total cholesterol, high-density lipoprotein cholesterol, blood glucose, blood pressure, cigarette smoking and body mass index) and the following variables were measured: fibrinogen, plasminogen activator inhibitor-1 (PAI-1), lipoprotein(a) [Lp(a)], total homocysteine, plasma folates, vitamin B12, high sensitivity C-reactive protein and C3 complement. Most patients were taking beta-blockers, ACE inhibitors and statins. Accordingly, patients had lower blood pressure and cholesterol values than controls. Moreover, they consumed less alcohol and coffee and did not differ from controls in cigarette smoking and body mass index. Conversely, patients had higher levels of homocysteine, fibrinogen, C3 complement and Lp(a), although of these factors only C3 and homocysteine remained significantly associated with PMI in multivariate analysis. C-reactive protein, PAI-1 and especially C3 often correlated with traditional risk factors in controls, but these correlations tended to disappear or reverse in PMI patients. Fibrinogen inversely correlated with alcohol consumption. Homocysteine correlated (inversely) with plasma folates only. Lp(a) did not correlate with any variable. CONCLUSIONS Forty-seven patients with previous myocardial infarction displayed an excellent control of traditional risk factors, but they had higher mean C3 and homocysteine levels than the control group.

Abstract
BACKGROUND It has been shown that poor patient satisfaction can lead to poor adherence to treatment with consequently poor health outcomes. In order to improve the quality of care perceived by the patient and thus the health outcome, it is important to understand which are the main factors influencing patient satisfaction. OBJECTIVES To examine factors associated with patient satisfaction with care among dermatological out-patients. METHODS This longitudinal study is based on a sample of dermatology out-patients. The independent effects on patient's satisfaction of patient characteristics (sociodemographic characteristics, disease severity, quality of life) and of specific aspects of provided health care (the time the physician spent with patients, physician's interpersonal skills, etc.) were examined by multiple logistic regression. RESULTS A total of 1389 out-patients were selected at random and invited to participate. Of the 722 patients who agreed to participate, 424 fulfilled the inclusion criteria and 396 of these patients (93.4%) completed the study. Overall satisfaction was reported by 60.0% of patients. The likelihood of overall satisfaction was found to be significantly and independently increased by the physician's ability to give explanations and to show empathy for the patient's condition, and by the older age of patients. The likelihood of satisfaction also increased with increasing disease severity, but decreased with symptom-related poor quality of life. The lowest level of satisfaction was found among patients whose symptom-related quality of life was worse than the clinical severity rated by the dermatologist. CONCLUSIONS Improving the physician's interpersonal skills can increase patient satisfaction, which is likely to have a positive effect on treatment adherence and health outcomes. Dermatologists succeeded better in establishing a good relationship with clinically more severely affected patients than with patients who were clinically mildly affected despite their quality of life being impaired. Thus, the inclusion of a patient-rated quality of life can be a useful measure in dermatology, as it enables clinicians to perceive the patients' perception of their health status.

Abstract
Endothelial dysfunction is an early event in atherosclerosis and could be considered a response to the injury induced by major risk factors. There is evidence that endothelial dysfunction is intimately involved in the onset and the progression of cardiovascular disease through abnormalities in the production, release or degradation of endothelium-derived factors, mainly nitric oxide and endothelin 1. Several reports have shown that drugs of the statin class could have multiple beneficial effects related to endothelium-mediated vasoactive, antithrombotic, antiproliferative and anti-inflammatory actions. Thus, the question arises of whether endothelial cells are the main target of statin therapy, in the setting of both hypercholesterolemia and normocholesterolemia. Experimental and clinical studies are reported that could support this hypothesis.

Abstract
C3 complement is produced in response to macrophage activation and is a reliable marker of the risk of myocardial infarction in men. This study was designed to ascertain whether the treatment with atorvastatin, a powerful cholesterol lowering drug, and/or vitamin E, a natural antioxidant, may induce a short term decrease in serum C3 in subjects with persistently elevated levels. From an initial random sample of 1100 men aged 55-64 years, 140 subjects with 3 consecutive C3 measurements in the high tertile (>1.19 g/l) were selected. Those with total cholesterol <5.56 mmol/l were double blindly randomized in groups 1 (placebo, N = 28, G1) and 2 (vitamin E 600 IU/day, N= 30, G2). The subjects with total cholesterol values >5.56 mmol/l were randomized in groups 3 (placebo, N= 30, G3), 4 (atorvastatin 10 mg/day, N = 27, G4) and 5 (atorvastatin 10 mg/day + vitamin E 600 IU/day, N = 25, G5). After 3 months C3 levels were substantially unchanged in the first 4 groups, while in G5 a very significant decrement occurred: -0.070 g/l (5.2%); 95% CI 0.043-0.098; p <0.0001. "Normal" levels of C3 (< 1.19 g/l) were reached by 28% of G5 subjects. In G2 and G5 vitamin E levels increased by 60 and 36%, while in G4 they decreased by 23% (p < 0.0001), paralleling cholesterol and triglyceride fall. In all groups a progressive decrease in HDL cholesterol occurred (-17%, p < 0.0001). In conclusion, treatment with atorvastatin plus vitamin E for three months can lower persistently elevated C3 levels.

Abstract
Metoclopramide hydrochloride (MCPH) is dopamine antagonist antiemetic drug that binds D2 receptor at the central nervous system and peripheral levels, which stimulates the upper gastrointestinal tract motility. It is often used in the management of some forms of nausea and vomiting (1-3). Occupational allergy to drugs is seldom reported. No case of occupational allergy to MCPH have been reported, to date. We present a case of airborne allergic asthma in a worker employed in the synthesis of Metoclopramide hydrochloride.
