Abstract
The aim of this study was to compare patients' satisfaction, experience, objectives, and opinion based on their current opioid substitution therapy (OST) (buprenorphine/naloxone (B/N) or methadone). The PREDEPO study is an observational, cross-sectional, multicentric study performed in Spain. Adult patients diagnosed with opioid use disorder (OUD) receiving OST were included. They were asked to fill in a questionnaire regarding their current OST. A total of 98 patients were enrolled (B/N: 50%, methadone: 50%). Mean age was 47 ± 8 years old and 80% were male. Treatment satisfaction was similar between groups. The most frequently reported factor for being "very/quite satisfied" was "being able to distribute the dose at different times throughout the day" (44% B/N vs. 63% methadone; p = .122). A significantly lower proportion of patients in the B/N group versus the methadone group reported that having to collect the medication daily was "very/quite annoying" (19% vs. 52%, p = .032). Treatment objectives reported by the majority of patients were similar between groups ("not feeling in withdrawal anymore", "reduce/definitely stop drug use", "improve my health", and "stop thinking about using daily") except for "not having money problems anymore" (73% B/N vs. 92% methadone; p = .012). These results suggest there are several unmet expectations regarding current OST. There is a need for new treatments that reduce the burden of OUD, avoid the need for daily dosing, and are less stigmatizing which in turn could improve patient management, adherence and, quality of life.

Abstract
AIM The aim of the study was to assess the acceptance of patients with opioid use disorder (OUD) to switching their opioid dependence treatment (ODT) for a prolonged-release buprenorphine (PRB) injection according to their prior ODT (buprenorphine/naloxone [B/N] or methadone). METHODS This was an observational, retrospective/cross-sectional, multicentre study of adult patients diagnosed with OUD on ODT. Data collected from diaries were analysed to know their interest and opinion on PRB. Questions with fixed response options were included, and several Likert scales were used. RESULTS A total of 98 patients were enrolled (B/N: 50.0%, methadone: 50.0%). The mean age was 46.9 ± 8.43 years and 79.6% were males. PRB was similarly perceived by both groups in most variables analysed, receiving a mean score of 7.2/10 (B/N: 7.4, methadone: 7.0; p = 0.520), and approximately 65% of patients said they were willing to switch to PRB (B/N: 63.3%, methadone: 65.3%; p = 0.833). Of these, a higher percentage in the B/N group considered that switching would be easy/very easy (B/N: 90.3%, methadone: 46.9%; p < 0.001) and that they would start PRB when available (B/N: 64.5%, methadone: 34.3%; p = 0.005). More than 90% would prefer the monthly injection (B/N: 93.6%, methadone: 100%; p = 0.514). One-third of patients in both groups were unsure/would not switch their ODT to PRB (B/N: 36.7%, methadone: 34.7%; p = 0.833). The main reason was administration by injection. CONCLUSION Two-thirds of patients would switch their treatment for PRB, and most patients on B/N considered that switching would be easy. PRB could be a suitable alternative for OUD management.

Abstract
BACKGROUND In contrast to adults, only limited data are available on the human papillomavirus (HPV)-type spectrum in anogenital warts (AGW) of children. OBJECTIVE This study aimed to evaluate the HPV-type spectrum in AGW of prepubertal children. MATERIALS & METHODS In a retrospective German multicentre study, HPV genotyping was performed in AGW biopsies of 55 1- to 12-year-old children using HPV group-specific PCRs followed by hybridization with type-specific probes or sequence analysis. RESULTS Human papillomavirus-DNA was found in 53 of the 55 AGW. In 58.5% (31/53) of the HPV-positive AGW, mucosal HPV types were detected. HPV6 (27/53, 50.9%) was the predominant type. 43.4% (23/53) of the lesions were induced by cutaneous HPV types (HPV2, HPV27, HPV57). Mucosal HPV types were significantly more common in children under 5 years of age than in children 5 years of age and older (22/25, 88.0% [95% CI: 70.0-95.8] vs. 9/28, 32.1% [95% CI: 17.9-50.7], P < 0.001). In contrast, cutaneous HPV types were significantly more prevalent in the 5- to 12-year age group (4/25, 16.0% [95% CI 6.4-34.7] vs. 19/28, 67.9% [95% CI 49.3-82.1], P < 0.001). CONCLUSION Anogenital warts in 5- to 12-year-old children are frequently associated with cutaneous HPV types, possibly due to horizontal transmission. HPV typing, in addition to comprehensive clinical and psychosocial evaluation, can potentially help in the assessment of these cases.

Abstract
Background Following the first investigational study on the use of extracorporeal photopheresis for the treatment of cutaneous T‐cell lymphoma published in 1983, this technology has received continued use and further recognition for additional earlier as well as refractory forms. After the publication of the first guidelines for this technology in the JEADV in 2014, this technology has maintained additional promise in the treatment of other severe and refractory conditions in a multi‐disciplinary setting. It has confirmed recognition in well‐known documented conditions such as graft‐versus‐host disease after allogeneic bone marrow transplantation, systemic sclerosis, solid organ transplant rejection including lung, heart and liver and to a lesser extent inflammatory bowel disease. Materials and methods In order to further provide recognized expert practical guidelines for the use of this technology for all indications, the European Dermatology Forum (EDF) again proceeded to address these questions in the hands of the recognized experts within and outside the field of dermatology. This was done using the recognized and approved guidelines of EDF for this task. All authors had the opportunity to review each contribution as it was added. Results and conclusion These updated 2020 guidelines provide at present the most comprehensive available expert recommendations for the use of extracorporeal photopheresis based on the available published literature and expert consensus opinion. The guidelines are divided in two parts: PART I covers cutaneous T‐cell lymphoma, chronic graft‐versus‐host disease and acute graft‐versus‐host disease while PART II will cover scleroderma, solid organ transplantation, Crohn's disease, use of ECP in paediatrics practice, atopic dermatitis, type 1 diabetes, pemphigus, epidermolysis bullosa acquisita and erosive oral lichen planus.

Abstract
Adequate therapeutic management of cutaneous T-cell lymphoma (CTCL) requires the identification of the exact CTCL stage and entity within the current WHO classification. There is no curative therapy for CTCL yet, so that treatment currently aims at improving symptoms and quality of life as well as reducing relapse rates. The treatment has to be stage-adapted. Therapeutic options comprise skin-directed as well as systemic treatment. In early stages, phototherapy and local steroids are the first-line therapeutic options. For the therapy of higher stages, interferon alpha and the RXR-specific retinoid bexarotene are used as first-line medications. Second-line treatment comprises monochemotherapy with agents like gemcitabine or liposomal doxorubicine. Nevertheless, the high relapse rates in higher stages make novel alternative treatment options necessary. As future therapy, especially the fusion protein brentuximab-vedotin directed against CD30 shows promising potential in clinical studies.

Abstract
BACKGROUND Patients with erythrodermic disease are a diagnostic challenge regarding the clinical and histological differential diagnosis. OBJECTIVES To evaluate histopathological and immunohistochemical diagnostic markers for Sézary syndrome. METHODS Ninety-seven erythrodermic cases [Sézary syndrome (SS), n = 57; erythrodermic inflammatory dermatoses (EIDs), n = 40] were collected by the EORTC Cutaneous Lymphoma Task Force histopathology group. Evaluation criteria were (i) epidermal and dermal changes; (ii) morphology of the infiltrate; (iii) immunohistochemical analysis of marker loss (CD2, CD3, CD4, CD5 and CD7); (iv) bystander infiltrate by staining for CD8, FOXP3 and CD25; and (v) expression of Ki-67, CD30, PD-1 and MUM-1. RESULTS The workshop panel made a correct diagnosis of SS in 51% of cases (cutaneous T-cell lymphoma 81%) and of EID in 80% without clinical or laboratory data. Histology revealed a significantly increased degree of epidermotropism (P < 0.001) and more intraepidermal atypical lymphocytes (P = 0.0014) in SS biopsies compared with EID. Pautrier microabscesses were seen only in SS (23%) and not in EID (P = 0.0012). SS showed significantly more dermal cerebriform and blastic lymphocytes than EID. Immunohistochemistry revealed a significant loss of CD7 expression (< 50%) in 33 of 51 (65%) cases of SS compared with two of 35 (6%) EID (P < 0.001). The lymphocytic infiltrate in SS skin samples was found significantly to express PD-1 (P = 0.0053), MUM-1 (P = 0.0017) and Ki-67 (P < 0.001), and showed less infiltration of CD8(+) lymphocytes (P < 0.001). A multivariate analysis identified CD7 loss, increased numbers of small cerebriform lymphocytes, low numbers of CD8(+) lymphocytes and increased proliferation (Ki-67(+) lymphocytes) as the strongest indicators for the diagnosis of SS. CONCLUSIONS A number of different histological and immunophenotypical criteria are required to differentiate between SS and EIDs.

Abstract
BACKGROUND Primary cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group with Sézary syndrome (SS) as one of the most aggressive variants. Recently, we identified a loss of E2A as a recurrent event in SS, which enhanced proliferation via upregulation of the proto-oncogene MYC. MYC-induced transformation usually requires deleterious alterations of key apoptotic genes including p53; however, p53 functionality and mutation status in SS are unclear. OBJECTIVES We investigated functionality of p53 signalling by pharmacological treatment with the MDM2 antagonist nutlin-3, which might result in p53 activation. Furthermore, we analysed the TP53 mutation status in CTCL cell lines and highly purified tumour cells from patients with SS by mRNA and DNA sequencing. METHODS We analysed the apoptosis induction due to nutlin-3 treatment in various SS cell lines and primary patient samples by annexin V/propidium iodide staining. Induction of p53 target genes was analysed by immunoblotting, and TP53 was sequenced at the mRNA and DNA level. RESULTS We identified various TP53 mutations and an impaired p53 signalling in the vast majority of the investigated cell lines and primary SS cells. CONCLUSIONS In accordance with the importance of MYC deregulation in SS, p53 signalling is frequently nonfunctional in SS. However, although most likely ineffective as exclusive treatment in SS, it remains possible that pharmacological p53 activation could be beneficial in combination with other approaches including classical chemotherapeutics.

Abstract
Primary cutaneous T-cell lymphomas (CTCL) mycosis fungoides (Mf) and Sézary syndrome (SS) belong to the group of non-Hodgkin lymphomas which are characterized by clonally proliferating CD4+ cells localized in the skin. SS is a leukemic variant of CTCL and is characterized by erythroderma, generalized lymphadenopathy, and circulating atypical T-cells with cerebriform nuclei, so-called Sézary cells. Palmoplantar hyperkeratosis, generalized alopecia, and severe pruritus are additional symptoms that are associated with SS. Patients have a poor prognosis with an estimated five year survival of 12.5 to 27 percent and estimated median survival of 14.5 to 18 months. The incidence of MF and also SS has increased with time and may be in part due to improved clinical awareness and especially advances in diagnostic testing.

Abstract
8572 Background: Vorinostat, a histone deacetylase inhibitor, is registered for the treatment of advanced cutaneous T-cell lymphoma (CTCL) in the US. Preclinical studies suggest that vorinostat may enhance the activity of chemotherapeutic or biological anticancer agents in a variety of cancers. This Phase I, multicenter, open-label study systematically evaluated vorinostat combined with the retinoid bexarotene in patients (pts) with advanced CTCL. Methods: Eligible pts were aged ≥18 years with stage ≥IB progressive, persistent, or recurrent CTCL refractory to ≥1 systemic therapy. Primary objective was to determine the maximum tolerated dose (MTD). Phase Ia Part I: dose escalation of vorinostat (200–400 mg/day) and bexarotene (150–300 mg/m2/day); Part II: fixed vorinostat dose (400 mg/day) with bexarotene dose escalation (150–450 mg/day). Cycles were repeated every 28 days for ≤6 cycles. Clinical activity and safety of the combination was also assessed. Results: 23 pts received ≥1 dose of study medication. Three pts in dose level (DL) 2 experienced dose-limiting toxicities (DLTs) ( Table ). No DLTs were observed in the first cycle of DL 2a and 2b. The MTD (Part I) was vorinostat 200 mg/day plus bexarotene 300 mg/m2/day. The Part II MTD was not reached as the study was discontinued early due to low enrollment; no DLTs were observed at DL 6 or 7. The most common drug-related adverse events (DRAEs) were hypothyroidism (35%), fatigue (30%), and hypertriglyceridemia (30%). No Grade 4 or 5 DRAEs were reported and 4 pts had serious DRAEs (Grade ≤3). Eighteen pts have discontinued: 5 due to AEs, 5 due to progressive disease, and 8 withdrew consent. Of 22 pts evaluable for efficacy, 4 (18%) had an objective response, and 7 (32%) derived clinical benefit (pruritis relief). Conclusions: These preliminary data suggest that the vorinostat/bexarotene combination is feasible in pts with advanced CTCL; however, the dosage of either drug must be reduced to avoid unacceptable side effects.

Abstract
Primary cutaneous T-cell lymphomas (PCLs) mycosis fungoides (MF) and Sézary syndrome (Ss) belong to the group of non-Hodgkin lymphomas (NHL), which are characterized by clonally proliferating CD4+ cells localized in the skin. Although there already exist many conventional skin-directed and systemic cytotoxic treatment options, in long-term only a transient remission without curative results will be reached in most cases. The aim of this article was to present actual assumed treatment modalities, as well as new therapeutic strategies which passed already through clinical trials showing promising results in the treatment of PCLs.

Abstract
The aim of current therapy for cutaneous T-cell lymphoma (CTCL) is to induce clinically meaningful remission, provide symptom relief, improve patient quality of life (QoL) and prolong disease-free and overall survival. A key research question is whether such remissions or minimal disease status can be maintained in the long term. There have been few formal studies of maintenance therapy in CTCL. Some skin-directed therapies such as total-skin electron-beam therapy and high-dose psoralen plus ultraviolet A may not be considered suitable, because of the risk of long-term cumulative toxicities. Other therapies such as nitrogen mustard, interferon (IFN)-alpha and bexarotene have demonstrated positive effects in prolonging remissions in small numbers of patients. Large longitudinal studies are required to investigate the efficacy of maintenance treatments in CTCL and their impact on patients' QoL and overall survival. Of the systemic therapies currently approved for the treatment of CTCL, bexarotene and IFN-alpha are obvious candidates for testing, because they can be self-administered by the patient and provide good long-term tolerability.

Abstract
The management goal in cutaneous T-cell lymphomas (CTCLs) is to improve symptoms and induce remission. Early-stage disease is generally treated with skin-directed therapies. However, if these do not control the disease, systemic therapy becomes necessary. Bexarotene, a novel rexinoid, is an oral, noncytotoxic drug that has been approved in Europe for the treatment of refractory advanced-stage CTCL and in the U.S.A. for refractory CTCL. We provide guidance on the use of bexarotene in the management of CTCL, based on data from phase II/III clinical trials and the authors' clinical experience, and suggest how the potential of the drug can be maximized. The clinical trial results with bexarotene are reviewed, especially in comparison with interferon-alpha, which is the other commonly used noncytotoxic systemic therapy for CTCL. A treatment algorithm for bexarotene in refractory CTCL is suggested. As bexarotene may take time to achieve a maximum response, this algorithm recommends that therapy should be continued for a sufficient period to allow for a delayed onset of action. In addition, possible combination therapies with bexarotene are discussed. We conclude that bexarotene is effective in the management of CTCL, and has the advantage of oral administration. An on-going randomized clinical trial comparing psoralen plus ultraviolet A (PUVA) with PUVA plus bexarotene will provide valuable information about this combination regimen in early-stage disease, but further data are needed on the relative efficacies of other combination therapies with bexarotene in CTCL.

Abstract
The simultaneous manifestation of different lymphomas in the same patient or even in the same tissue, defined as composite lymphoma, is very rare. The exceptional case of a patient who, presented with simultaneous manifestation of three different lymphomas after 30 years of successful treatment of a nodal T cell lymphoma is reported here. The three lymphomas were: (1) primary cutaneous marginal zone B cell lymphoma (MZBL); (2) nodal Epstein-Barr virus (EBV)-associated classic Hodgkin's lymphoma (cHL) of the B cell type; and (3) peripheral T cell lymphoma coexisting in the skin and cervical lymph node. Immunohistochemical and molecular analyses showed different clonal origins of EBV-negative cutaneous MZBL and EBV-positive B cell cHL and, in addition, the presence of the same clonal T cell population in the skin and lymph node. The simultaneous occurrence of three different, clonally unrelated lymphomas in one patient at the same time has not been reported yet.

Abstract
Bexarotene is an oral retinoid therapy that is effective for the treatment of early and advanced-stage cutaneous T-cell lymphoma (CTCL) in patients who have failed on other therapies. However, bexarotene treatment is associated with unavoidable side-effects, in particular hypertriglyceridaemia and hypothyroidism, which are manageable with adequate concomitant medications and are reversible on cessation of treatment. A pragmatic strategy for minimizing bexarotene-associated hypertriglyceridaemia and hypothyroidism is suggested, based on data from the studies with bexarotene in CTCL and on day-to-day experience with this agent in the clinical setting. The strategy anticipates that these common adverse events are likely to occur and recommends the early use of preventive therapy to lower triglycerides and elevate thyroid hormone levels in the blood, followed by subsequent monitoring, dose adjustment during bexarotene treatment, and titration of the daily bexarotene dose from 150 to 300 mg m(-2), which is optimal for most patients. When further information becomes available on how bexarotene interacts with lipid metabolism and thyroid function, the management approach suggested here may need to be changed.

Overexpression of c- myb in Leukaemic and Non-Leukaemic Variants of Cutaneous T-Cell Lymphoma. Dermatology 2005; 211:84-92.

Abstract
BACKGROUND The c-myb oncogene is a transcription factor that regulates proliferation, differentiation and apoptosis of haematopoietic cells and activated T cells by binding to promoter sequences of such genes as c-myc or bcl-2 that are expressed in cutaneous T-cell lymphoma (CTCL). OBJECTIVE Our study was performed in order to evaluate c-myb expression as a quantitative parameter for differential diagnosis in leukaemic and non-leukaemic variants of CTCL. METHODS c-myb expression was analysed in lesional skin and in the peripheral blood of 21 patients with mycosis fungoides (MF), 15 patients with Sézary syndrome (SS) and 15 patients with inflammatory skin diseases using immunohistochemistry and semiquantitative as well as quantitative RT-PCR. RESULTS Immunohistochemistry confirmed expression of c-myb in the lesional skin of the majority of CTCL patients with a tendency towards higher expression in SS (1.86 +/- 0.5) versus MF (1.2 +/- 0.7) while c-myb was absent from the lesional skin of patients with inflammatory skin diseases. c-myb was overexpressed in the peripheral blood in all SS patients (100% SS vs. 35.7% MF) at a high expression level (51,335.31 +/- 31,960.32 AU in SS vs. 1,226.35 +/- 1,258.29 AU in MF using semiquantitative RT-PCR, and 5.72 x 10(-2) +/- 2.27 x 10(-2) in SS vs. 0.91 x 10(-2) +/- 1.18 x 10(-2) in MF vs. 0.24 x 10(-2) +/- 0.11 x 10(-2) in inflammatory skin disease using quantitative RT-PCR). CD4+ cells from the peripheral blood of SS patients and cell lines in vitro showed the highest c-myb expression levels upon quantitative RT-PCR (23.27 x 10(-2) and 10.78 x 10(-2) +/- 7.24 x 10(-2)). CONCLUSION Overexpression of c-myb in skin lesions of both non-leukaemic and leukaemic CTCL independent of the stage of the disease indicates that it acts early in disease development. Nevertheless, if positive, c-myb expression in lesional skin is a clear-cut diagnostic marker for CTCL as compared to inflammatory skin diseases. High-level expression of c-myb in the peripheral blood as assessed by quantitative RT-PCR constitutes an additional diagnostic parameter for SS and may be especially useful in cases in which morphological determination of Sézary cells or FACS analysis of CD7 and CD26 remain inconclusive.

Abstract
Mycosis fungoides (MF) and Sezary syndrome (SS) are the most common clinical variants of cutaneous T cell lymphoma. Although thought to be closely related to mature T helper cells, the relation between the neoplastic cells in MF and SS is still not fully clarified. This report describes a patient with complete remission of SS under treatment with extracorporeal photophoresis (ECP), who subsequently developed typical plaques of MF and large cell lymphoma (LCL). Serial polymerase chain reaction analyses confirmed identical T cell receptor beta and gamma gene rearrangements in SS, MF, and LCL, and complete disappearance of the circulating malignant T cell clone from the peripheral blood after ECP. These findings indicate that the neoplastic cells in SS, MF, and LCL are derived from a common precursor T cell, despite the change in clinical phenotype.

Abstract
Composite lymphomas are defined as two unrelated, morphologically and genetically distinct lymphomas occurring at the same point in time within the same tissue or organ. Since their original definition, several composite lymphomas have been reported exclusively based on morphological grounds. However, with the application of immunohistological and molecular biological techniques it has become evident that many so called "composite" lymphomas do not fulfil the necessary criteria, because they merely represent two different morphological phenotypes of the same malignant clone. This report describes the manifestation of a true composite lymphoma within a single cervical lymph node, which is composed of a cutaneous T cell lymphoma and a classic Hodgkin lymphoma of B cell type--a very rare finding indeed.
