The ATTRACT study: screening for the early identification of axial psoriatic arthritis in a cohort of Italian psoriatic patients.

OBJECTIVE: There is growing interest in the early identification of patients with axial psoriatic arthritis (axPsA). We aimed to evaluate whether a dermatology-based screening strategy could help to identify axPsA patients. METHODS: The dermatologist-centered screening (DCS) questionnaire was administrated by Dermatologists to consecutive patients fulfilling the inclusion criteria (1. age ≥ 18 years and 2. clinical diagnosis of psoriasis made by a dermatologist) to identify patients eligible (affirmative answers 1-3c of the DCS) for rheumatological evaluation. Clinical, laboratory, genetic, and imaging data were collected from all referred patients. RESULTS: Among the 365 patients screened, 265 fulfilled the inclusion criteria and 124/265 (46.8%) were eligible for rheumatological referral. Diagnosis of axPsA, with or without peripheral PsA (pPsA), was made in 36/124 (29.0%) patients; pPsA without axial involvement was found in 21/124 (16.9%) patients. Back pain at screening was recorded in 174 (66%) patients, with 158 (60%) reporting a back pain duration longer than 3 months, and 140 (53%) reporting back pain onset before the age of 45. Active inflammatory and/or structural post-inflammatory changes in the sacroiliac joints and/or spine were observed in all axPsA patients.Patients with PsA showed a numerically longer duration of back pain and higher CRP levels in comparison with patients with Pso without PsA. CONCLUSION: The DCS tool proved to be a valuable screening strategy for detecting and characterizing patients with axPsA in a real-life cohort of psoriasis patients in a dermatological setting and helped to identify a substantial number of patients affected by undiagnosed pPsA.

Prognosis in early stage cutaneous T-cell lymphoma treated with psoralen plus ultraviolet A irradiation and low-dose interferon-α: Long-term efficacy and survival according to conventional and emerging clinical endpoints.

Patients with early stage cutaneous T cell lymphoma (CTCL) usually have a benign and chronic disease course, characterized by temporally response to conventional skin directed therapies and intrinsic possibility to evolve. Using the combination of psoralen plus ultraviolet A irradiation (PUVA) and low-dose interferon-α (INF), the principal treatment goal is to keep confined the disease to the skin, preventing disease progression. Among 87 patients with early stage IA to IIA MF treated with low-dose IFN-α2b and PUVA in our center, complete remission (CR) were reported in 70 patients (80.5%) and the overall response rate (ORR) was 97.8% (n = 85), with a median time to best response to therapy of 5 months (range, 1-30). Among the responders, only the 8% of patients had a relapse with major event. The median follow-up was 207 months (range, 6-295). Survival data showed a median overall survival (OS) not reached (95% CI; 235-NR months), a disease free survival (DFS) of 210 months (95% CI; 200-226 months) and a median time to next treatment (TTNT) of 38.5 months (95% CI, 33-46 months). The long follow up of this study verifies our preliminary results already published in 2006 and confirms the efficacy of INF-PUVA combination therapy in a real world setting, according conventional (OS and DFS) and emerging (TTNT) clinical endpoint of treatment efficacy.

Clinical outcomes and feasibility of the multidisciplinary management of patients with psoriatic arthritis: two-year clinical experience of a dermo-rheumatologic clinic.

Psoriatic arthritis (PsA) is a chronic inflammatory autoimmune arthritis, occurring in patients with psoriasis (Pso), that may affect the whole musculoskeletal system but also nails, eye, and gastrointestinal tract. Dermatologists and rheumatologists usually manage Pso and PsA separately, but early diagnosis and integrated management could achieve better outcomes of both skin and musculoskeletal manifestations, thus improving the health-related quality of life (HRQoL) of patients. In this work, we have described a model of integrated dermo-rheumatologic approach for the early diagnosis of PsA and to present the outcomes of the multidisciplinary management of PsA patients after 48 weeks of follow-up. Pso patients complaining musculoskeletal symptoms were enrolled in a DErmo-Rheumatologic Clinic (DERC) in order to screen, classify, and treat patients with PsA, employing an operative working procedure and a specific flowchart. The integrated dermatologic and rheumatologic management of PsA patients allowed a prompt establishment of the diagnosis and the best therapeutic approach in these patients, with a significant improvement of skin and articular diseases and, eventually, a consistent amelioration of HRQoL. Dermatologists and rheumatologists usually manage the "psoriatic disease" in separated outpatient clinics. In our study, we have demonstrated that a combined DERC, by means of a tight cooperation between the dermatologist and the rheumatologist, which use a specific working procedure and treatment flowchart, may achieve the optimal clinical management of these patients, with a consistent clinical remission of the disease and a significant amelioration of the HRQoL.

Correlation between immunohistochemical staining of CEACAM1 and clinicopathological findings in oral pre-neoplastic lesions and squamous cell carcinoma.

Squamous cell carcinoma of the oral cavity represents the sixth most common cancer worldwide and it is often preceded by pre-neoplastic lesions. Sometimes it is still difficult for pathologists to make objective differential diagnoses only on histological characteristics. Tumorigenesis is accompanied by altered expression of cell adhesion molecules, like carcinoembryonic antigen cell adhesion molecule (CEACAM)1. We wanted to investigative CEACAM1 in oral dysplastic lesions, carcinoma in situ (CIS) and oral squamous cell carcinoma (OSCC). We examined immunohistochemical CEACAM1 expression in 50 OSCC, 30 oral CIS and 40 pre-neoplastic lesions and assessed its correlation with clinical and pathological parameters. CEACAM1 was not expressed in normal mucosa, significantly expressed in CIS while it was negative in all the dysplastic lesions. In OSCC, high CEACAM1 expression was associated with tumor grade and inversely correlated with both overall and disease-specific 5-year survival. We showed that CEACAM1 expression is very dynamic: absent in dysplastic lesions, up-regulated in CIS and OSCC. We suggest that CEACAM1 could be a prognostic marker of OSCC and oral CIS. Our most important finding was that it could help pathologists diagnosing oral carcinoma in situ.

A validation study of the Simple Psoriatic Arthritis Screening (SiPAS) questionnaire to screen psoriasis patients for psoriatic arthritis.

OBJECTIVES: To validate in a multicentric cohort of patients a self-administered PsA screening tool, called Simple Psoriatic Arthritis Screening (SiPAS) questionnaire, to screen psoriasis patients for signs and symptoms of PsA. METHODS: The SiPAS questionnaire was validated in a multicentric Italian cohort of psoriasis patients referred to two rheumatological centres. RESULTS: A total of 202 psoriasis patients were screened with SiPAS in the validation study. Sixty-two psoriasis patients (30.7%) were diagnosed with PsA. The five screening questions (1. Have you ever had a finger or a toe and/or another joint swollen and painful without any apparent reason?; 2. Occasionally, has an entire finger or toe become swollen, making it look like a 'sausage'?; 3. Do you wake up at night because of low back pain?; 4. Have you had pain in your heels?; 5. Has a doctor ever diagnosed you with psoriatic arthritis?) with a dichotomous response, demonstrated high sensitivity and specificity for predicting PsA. Likelihood ratios for individual parameters varied between 2.06 and 4.75. Using the Bayesian Analysis, the presence of three of five items answered as "yes" showed respectively a sensibility and a specificity of 79% and 87%, with a positive likelihood ratio of 6.14. CONCLUSIONS: The SiPAS questionnaire is able to quickly screen psoriasis patients for PsA. A SiPAS score ≥3 is an indication for referral to a rheumatologist. The SiPAS needs further validation.

Prognostic value of CD44 expression in penile squamous cell carcinoma: a pilot study.

BACKGROUND: Several studies have reported on the prognostic value of molecular markers for metastasis risk and survival in penile squamous cell carcinoma (SCC) patients. The usefulness of CD44 expression as such a marker has been studied in different tumors, but not in penile SCC. Our aim was to determine whether CD44 expression may serve as a prognostic marker for lymph node metastasis and survival in penile SCC patients. METHODS: CD44 immunoistochemical expression was investigated in tissue specimens from 39 patients with penile SCC. CD44 cell positivity, staining intensity and distribution were analyzed and correlated with tumor stage, grade, lymph node status and disease-specific survival. RESULTS: CD44 expression was detected in epithelial cells of both intratumoral and normal tissues with different intensities and staining distributions. In normal tissues CD44 protein was mainly detected in cell membranes, whereas in the tumor compartments it was found in both the cell membranes and the cytoplasm. The intensities and percentages of CD44 expressing cells did not correlate with tumor stage and/or grade. Seventy-three percent of the patients with lymph node metastasis showed high intensities of CD44 staining, as compared to 44% of the patients without lymph node metastasis (P = 0.03). Lymph node-positive patients showed both cytoplasmic and membranous CD44 expression. High CD44 expression was found to be significantly correlated with a decreased 5 year overall survival (P = 0.01). CONCLUSIONS: CD44 levels and patterns of expression can be considered as markers for penile SCC aggressiveness and, in addition, may serve as predictive markers for lymph node metastasis, also in patients with clinically negative lymph nodes. CD44 expression may provide prognostic information for penile SCC patients, next to classical clinical-pathological factors.

D2-40 immunoreactivity in penile squamous cell carcinoma: a marker of aggressiveness.

D2-40 immunohistochemical expression was investigated in tissue specimens from 39 patients with squamous cell carcinoma of the penis who underwent partial or total penectomy between 1987 and 2008. Patient age, tumor size, and grade; D2-40-positive lymphatic vessel density in intratumoral, peritumoral, and normal tissue; cell positivity for D2-40 in intratumoral and normal tissue; and D2-40 staining intensity and distribution were analyzed and correlated with disease-specific survival. Analysis of D2-40-positive lymphatics disclosed that mean lymphatic vessel density was greater in peritumoral tissue than in intratumoral and normal tissue and lower in patients with lymph node metastasis than in those without lymph node metastasis. The receiver operating characteristic curve showed that an intratumoral lymphatic vessel density greater than 2.0 had 83.3% sensitivity and 78% specificity in predicting lymph node metastasis. Analysis of cell immunoreactivity showed cytoplasmic D2-40 positivity in intratumoral and normal tissue in 89.7% and 65.5% of patients, respectively. A strong correlation emerged between grade of cell differentiation and D2-40 immunoreactivity in intratumoral tissue; in particular, 88.9% of tumors with weak podoplanin expression were G1, whereas strong cellular immunoreactivity was detected in 83.3% of G3 patients (P = .003; χ(2) test). A significant correlation was also noted between pattern of reactivity and tumor grade because the basal layer was positive in patients with undifferentiated tumors (100% of G3) and in 72.2% of G1 tumors (P = .021; χ(2) test). D2-40 seems to be a useful marker for the development of node metastasis in squamous cell carcinoma of the penis, although validation in larger series is required to confirm its predictive value.

A patient with psoriasis and vitiligo treated with etanercept.

Psoriasis is a chronic, immune-mediated, inflammatory dermatosis whose aetiopathogenesis remains unclear, although tumour necrosis factor alpha (TNFalpha) appears to play a crucial role. The biological potential of TNFalpha inhibitors, such as etanercept, which reduce the inflammatory cascade, has radically changed the therapeutic management of patients with psoriasis and other immunomediated inflammatory diseases, associated with TNFalpha. The pathogenesis of the selective destruction of melanocytes in vitiligo is not fully understood, although there is growing evidence that several T helper type 1 cytokines, particularly TNFalpha, may be involved in the depigmentation process. A patient is described who presented with both psoriasis and vitiligo, and was treated with etanercept. After 24 weeks of therapy, the patient's psoriasis had improved markedly and the patient noted a mild improvement of vitiligo, with a reduction in macules and repigmentation in the scapular region.

Lesional skin chemokine CTACK/CCL27 expression in mycosis fungoides and disease control by IFN-alpha and PUVA therapy.

Recruitment of neoplastic T cells to skin is a critical step in the pathogenesis of mycosis fungoides (MF) lesions. Cutaneous T-cell attracting chemokine (CTACK)/CCL27 attracts memory T cells to skin, resulting in increased cutaneous expression. The interactions between neoplastic cells and skin immune system require further elucidation. CTACK/CCL27 expression and density of dendritic cells (DC), CD8+ and CD4+ lymphocytes were investigated in skin lesions of 52 early-stage MF patients treated by interferon (IFN)-alpha in combination with photochemotherapy (psoralen plus ultraviolet A, PUVA). Skin lesion biopsies obtained at diagnosis and after treatment were studied by immunohistochemistry. Initial CTACK/CCL27 expression was abnormal/suprabasal in 36 patients. Normal/basal CTACK/CCL27 expression tended to correlate with a high DC density and low CD4+ cell density in the neoplastic infiltrate. Treatment induced a significant increase in CTACK/CCL27 expression (chi(2) test: P=0.004). Overall, 33 patients relapsed [median event-free survival (EFS), 46 months] during follow-up (median, 92.5 months, range, 43-165). Normal/basal CTACK/CCL27 expression at the end of treatment correlated with lower rates of recurrence and a longer median EFS (111 months vs. 39 months with suprabasal expression; log rank test: P=0.031). CTACK/CCL27 overexpression in early-stage MF might thus be related to a balance between neoplastic cells and immunomodulant DC. Normal CTACK/CCL27 expression after treatment designates a subset of patients with favorable disease behavior. The mechanisms underpinning CTACK/CCL27 overexpression after therapy in the remaining patients, who are at greater risk of recurrence, warrant further investigation.

Lichen striatus in adults and pimecrolimus: open, off-label clinical study.

BACKGROUND: Lichen striatus is a well-known, acquired, self-healing, linear inflammatory dermatosis. Lichen striatus occurring in adults tends to be more extensive and itchy than in children, sometimes requiring symptomatic treatment. The therapeutic approach usually adopted is topical steroids, even though prolonged use may lead to several side-effects, particularly cutaneous atrophy. OBJECTIVE: To report the results of an open, off-label study on the use of pimecrolimus 1% in the treatment of diffuse, nonresponsive forms of lichen striatus. METHODS: Three adult patients suffering from relapsing or disseminated and itchy lichen striatus received topical application of pimecrolimus 1% cream (Elidel, Novartis Pharma, Basle, Switzerland) twice daily for 6 weeks, or until complete disappearance of the cutaneous lesions. RESULTS: All patients experienced rapid healing of the dermatosis, without any recurrence for at least 14 months. CONCLUSION: Our preliminary results show that pimecrolimus may represent a useful therapeutic alternative for lichen striatus, although further studies on a larger number of cases are needed to confirm its safety and efficacy in the treatment of this condition.

Clinicopathological features of primary cutaneous B-cell lymphomas from an academic regional hospital in central Italy: no evidence of Borrelia burgdorferi association.

We reviewed the clinico-pathological features of 73 primary cutaneous B-cell lymphomas (PCBCLs), diagnosed in 10 years in Marche region in central Italy, which included 16 marginal zone lymphomas (MZL), 33 follicle centre lymphomas (FCL) and 24 diffuse large B cell lymphomas (DLBCL). We also investigated the presence of Borrelia burgdorferi in tissues by polymerase chain reaction. Differences in age, sex, location site, response to therapy, disease recurrence and 5-year disease-specific survival were observed among the 3 histological groups. Specific DNA sequences of Borrelia burgdorferi were not detected in any of the 73 cases of PCBCL. We conclude that PCBCLs in Marche region behave according to the literature data and do not seem to be associated with Borrelia burgdorferi. Additional investigations should be performed on other possible etiologies, at least in our geographical area.

Indications for excision of nevi and melanoma diagnosed in a pediatric surgical unit.

BACKGROUND/PURPOSE: Childhood melanoma is rare but increasing in incidence. Its management relies on early diagnosis. The purpose of this study is to discuss surgical indications of nevi and diagnosis of melanoma in a pediatric surgical unit. METHODS: Data relative to the patients who underwent removal of nevi in our pediatric surgical unit from 1999 to 2005 were reviewed to identify indications, histology, and melanoma occurrence. RESULTS: The most frequent indication was atypical nevus. Compound nevus was the most common finding, followed by congenital and Spitz nevi. Melanoma was diagnosed in 3 excised nevi, and in 1 case it occurred as a metastatic disease. CONCLUSIONS: Our data showed a pattern of indications for surgery similar to that described in the literature, with a high detection rate of melanoma, nonetheless showing that some rare conditions may delay diagnosis.

Atypical neurothekeoma: a new case and review of the literature.

BACKGROUND: Neurothekeoma is a rare neoplasm ascribed into the broad category of benign peripheral nerve sheath tumors. The atypical cellular variant of this neoplasm, showing a peculiar histological pattern, has been very rarely reported in literature. METHODS: The clinical, histopathological and immunohistochemical profile of a new case of atypical cellular neurothekeoma in a 32-year-old woman is reported. RESULTS: The described neoplasm showed the histological features of atypical variant of cellular neurothekeoma with high-rate mitotic activity and deep penetration into subcutaneous fat. CONCLUSIONS: Because only few cases of atypical neurothekeoma have been reported in literature, clinical and morphological available data on this neoplasm are very few, and its prognosis remains uncertain; anyway, dermatologists should be aware of histological features of this neoplasm for which a complete surgical excision is recommended.

A case of follicular mycosis fungoides with follicular mucinosis: a rare association.

Follicular mycosis fungoides (FMF) is a rare cutaneous T cell lymphoma characterized by an atypical lymphoid infiltrate spreading within and around hair follicles without epidermotropism or follicular mucin deposits. Its occasional presentation with minimal epidermal involvement and/or follicular mucinosis suggests the need for uniform histologic criteria. We describe a new case of FMF associated with follicular mucinosis and discuss its morphologic spectrum of presentation.
