DNA Methylation of POMC and NR3C1-1F and Its Implication in Major Depressive Disorder and Electroconvulsive Therapy.

Introduction: Precision medicine in psychiatry is still in its infancy. To establish patient-tailored treatment, adequate indicators predicting treatment response are required. Electroconvulsive therapy (ECT) is considered one of the most effective options for pharmacoresistant major depressive disorder (MDD), yet remission rates were reported to be below 50%.

Novel candidate genes for ECT response prediction-a pilot study analyzing the DNA methylome of depressed patients receiving electroconvulsive therapy.

Background: Major depressive disorder (MDD) represents a serious global health concern. The urge for efficient MDD treatment strategies is presently hindered by the incomplete knowledge of its underlying pathomechanism. Despite recent progress (highlighting both genetics and the environment, and thus DNA methylation, to be relevant for its development), 30-50% of MDD patients still fail to reach remission with standard treatment approaches.

Daylight photodynamic therapy for severe facial and scalp actinic keratosis: a prospective non-sponsored single-centre study employing the actinic keratosis area and severity index (AKASI).

Daylight photodynamic therapy (DL-PDT) is an effective and convenient treatment for multiple actinic keratosis (AKs). There are limited tools to evaluate the outcome of AK treatment. Recently, the actinic keratosis area and severity index (AKASI) has been proposed as a quantitative tool for assessing AK severity.

Patterns of infiltration and local recurrences of various types of cutaneous sarcomas following three-dimensional histology.

Background: Cutaneous sarcomas are rare and characterized by pathogenetic heterogeneity. Knowledge about local infiltration patterns and recurrence rates may be useful in improving patient care and outcomes. The objective of the present study was to compare these two characteristics in sarcomas that had been treated using the identical surgical procedure.

Patient satisfaction in 1,827 patients following various methods of facial reconstruction based on age, defect size and site.

Background: Defect coverage following tumor excision requires a case-by-case decision as regards the optimal reconstruction technique. In the head and neck region in particular, the cosmetic outcome is of major importance. The objective of the present study was to compare various reconstruction methods in terms of their functional and aesthetic outcome based on patient age, defect size and site.

Patientenzufriedenheit von 1827 Patienten nach verschiedenen Rekonstruktionsmethoden im Gesichtsbereich in Abhängigkeit von Alter, Defektgröße und Lokalisation.

Hintergrund: Nach Tumoroperationen erfolgt ein Defektverschluss mit den für den individuellen Fall optimalen chirurgischen Methoden. Besonders im Kopf-Hals--Bereich ist das Ergebnis sehr wichtig. Ziel der retrospektiven Studie war es, Rekonstruktionsmethoden von Defekten entsprechend Alter, Lokalisation und Größe nach funktionellen und ästhetischen Gesichtspunkten zu vergleichen.

Diagnostic value of autoantibody titres in patients with bullous pemphigoid.

Background: Bullous pemphigoid (BP) is the most common autoimmune blistering disease of the skin requiring skin and serum tests for a precise diagnosis.

Objectives: We analysed the sensitivity and specificity of BP-relevant parameters and the value of autoantibody titres during follow-up of BP patients.

Materials & Methods: In a retrospective single-centre study, we included 200 consecutive patients with BP and 400 non-BP patients, and evaluated the test results of patients' serum and skin.

Anthralin modulates the expression pattern of cytokeratins and antimicrobial peptides by psoriatic keratinocytes.

Background: Psoriasis is an inflammatory skin disease with aberrant keratinocyte proliferation, presumably as a result of immune cell activation. Th17 cytokines like IL-17A and IL-22 are critically implicated in epidermal thickening, altered keratinocyte differentiation and production of innate factors such as antimicrobial peptides. Psoriasis treatment options include modern targeted therapies using anti-cytokine antibodies and traditional non-targeted treatments like anthralin (dithranol).

Surgical treatment of rhinophyma: experience from a German cohort of 70 patients.

Rhinophyma is a deforming soft tissue hyperplasia of the nose and surgical removal represents the treatment of choice. Comprehensive data on surgical therapy and the impact of rhinophyma on patient quality of life are lacking. Patients who received surgery for rhinophyma between 2006 and 2015 were retrospectively evaluated for postoperative complications, clinical outcome, recurrence of rhinophyma, and the impact of rhinophyma on daily life.

Nutritional control of IL-23/Th17-mediated autoimmune disease through HO-1/STAT3 activation.

The nutritional curcumin (CUR) is beneficial in cell-mediated autoimmune diseases. The molecular mechanisms underlying this food-mediated silencing of inflammatory immune responses are poorly understood. By investigating antigen-specific immune responses we found that dietary CUR impairs the differentiation of Th1/Th17 cells in vivo during encephalomyelitis and instead promoted Th2 cells.

Intraläsionale Therapie niedrig maligner primär kutaner B-Zell-Lymphome mit Anti-CD20-Antikörper: Nebenwirkungen korrelieren mit gutem klinischen Ansprechen.

Hintergrund Und Ziel: Die intraläsionale Gabe von Anti-CD20-Antikörpern (Rituximab) wurde als effektive Therapieoption für Patienten mit niedrig malignen primär kutanen B-Zell-Lymphomen beschrieben. Bis heute wurden allerdings keine Parameter identifiziert, welche reproduzierbar ein gutes klinisches Ansprechen dieser Therapie vorhersagen. Ziel dieser Studie ist, sowohl das klinische Ansprechen und die unerwünschten Nebenwirkungen als auch die Patientenwahrnehmung hinsichtlich intraläsionaler Injektionen von anti-CD20-Antikörpern zur Behandlung indolenter primär kutaner B-Zell-Lymphome im Vergleich mit anderen Therapien zu evaluieren.

Intralesional anti-CD20 antibody for low-grade primary cutaneous B-cell lymphoma: Adverse reactions correlate with favorable clinical outcome.

Background And Objectives: Intralesional injection of anti-CD20 antibody (rituximab) has been described as effective therapeutic option for patients with indolent primary cutaneous B-cell lymphoma (PCBL). To date, no parameters that reproducibly predict favorable clinical outcome of this treatment have been identified. The study aims to evaluate the clinical response and adverse effects as well as patients' self-perception of intralesional injection of anti-CD20 antibody for treatment of indolent PCBL compared to other treatment modalities.

Silencing of ASC in Cutaneous Squamous Cell Carcinoma.

Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is an important adaptor protein for inflammasome activation, mediating the secretion of protumorigenic innate cytokines. However, ASC is also known to trigger apoptosis in tumor cells, acting as a tumor-suppressor gene, which is lost in several human cancers. The aim of this study was to evaluate the clinical significance of ASC in human cutaneous squamous cell carcinoma (SCC).

Recent advances in understanding psoriasis.

T helper (Th) cells producing interleukin (IL)-17, IL-22, and tumor necrosis factor (TNF) form the key T cell population driving psoriasis pathogenesis. They orchestrate the inflammation in the skin that results in the proliferation of keratinocytes and endothelial cells. Besides Th17 cells, other immune cells that are capable of producing IL-17-associated cytokines participate in psoriatic inflammation.

MALT1 Protease Activity Controls the Expression of Inflammatory Genes in Keratinocytes upon Zymosan Stimulation.

The protease activity of the paracaspase mucosa-associated lymphoid tissue lymphoma translocation gene 1 (MALT1) plays an important role in antigen receptor-mediated lymphocyte activation by controlling the activity of the transcription factor nuclear factor-κB and is thus essential for the expression of inflammatory target genes. MALT1 is not only present in cells of the hematopoietic lineage, but is ubiquitously expressed. Here we report that stimulation with zymosan or Staphylococcus aureus induced MALT1 protease activity in human primary keratinocytes.

Restless legs syndrome in psoriasis: an unexpected comorbidity.

Background: Restless legs syndrome (RLS) is characterized by unpleasant sensations in the legs and an uncontrollable urge to move them in order to gain relief. Higher frequencies of RLS have been reported in systemic lupus, multiple sclerosis, rheumatoid arthritis and atopic dermatitis.

Objectives: Since the disease-related stress present in psoriasis is similar to the stress of those diseases, we aimed to study the frequency of RLS in a German cohort of patients with psoriasis.

Germinal center reentries of BCL2-overexpressing B cells drive follicular lymphoma progression.

It has recently been demonstrated that memory B cells can reenter and reengage germinal center (GC) reactions, opening the possibility that multi-hit lymphomagenesis gradually occurs throughout life during successive immunological challenges. Here, we investigated this scenario in follicular lymphoma (FL), an indolent GC-derived malignancy. We developed a mouse model that recapitulates the FL hallmark t(14;18) translocation, which results in constitutive activation of antiapoptotic protein B cell lymphoma 2 (BCL2) in a subset of B cells, and applied a combination of molecular and immunofluorescence approaches to track normal and t(14;18)(+) memory B cells in human and BCL2-overexpressing B cells in murine lymphoid tissues.

Three dimensional (3D) histology in daily routine: practical implementation and its evaluation.

Background: The continuous evaluation of the edges of a tumor by means of three-dimensional (3D) histology often appears complicated and require the surgeon and dermatopathologist to work together closely. We present clear rules that allow communication between all parties involved and then verify their application in daily routine.

Methods: Tissue processing, interpretation of results, as well as communication between the surgeon and the dermatopathologist are based on an algorithm with the aid of exact times and embedding cassettes, which allow precise topographic orientation.

Early lesions of follicular lymphoma: a genetic perspective.

The pathogenesis of follicular lymphoma is a multi-hit process progressing over many years through the accumulation of numerous genetic alterations. Besides the hallmark t(14;18), it is still unclear which other oncogenic hits contribute to the early steps of transformation and in which precursor stages these occur. To address this issue, we performed high-resolution comparative genomic hybridization microarrays on laser-capture micro-dissected cases of follicular lymphoma in situ (n=4), partial involvement by follicular lymphoma (n=4), and duodenal follicular lymphoma (n=4), assumed to represent, potentially, the earliest stages in the evolution of follicular lymphoma.

Cutaneous presentation of hematological malignancies.

Systemic hematological malignancies can present in the skin as specific secondary cutaneous lymphoma or as non-specific skin manifestations. In the majority of cases, patients are first diagnosed with a systemic lymphoma and may subsequently develop skin involvement. Rarely, the cutaneous symptoms precede the diagnosis of systemic hematological disorders.

Aberrant T-cell antigen expression in classical Hodgkin lymphoma is associated with decreased event-free survival and overall survival.

Hodgkin/Reed-Sternberg (HRS) cells of classical Hodgkin lymphoma (cHL) rarely express T-cell-associated antigens (TCA), but the clinical significance of this finding is uncertain. Fifty cHLs expressing any TCA on the HRS cells (TCA-cHL) were identified in two cohorts (National Cancer Institute, n = 38; Basel, n = 12). Diagnostic pathology data were examined in all cases with additional T-cell receptor γ rearrangements (TRG@) polymerase chain reaction (PCR) in a subset of cases.

Gray zone lymphoma: better treated like hodgkin lymphoma or mediastinal large B-cell lymphoma?

Although primary mediastinal large B-cell lymphoma (PMBL) and classic Hodgkin lymphoma of the nodular sclerosis type (CHL-NS) are distinct diseases, they share several clinical characteristics and biologic features. Given that, it is not surprising that there exist mediastinal lymphomas that do not fit well into either category but have clinical and morphologic features overlapping and transitional between PMBL and CHL-NS. The term mediastinal gray zone lymphoma (MGZL) has been used for these tumors, which are included in the World Health Organization classification as "B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classic Hodgkin lymphoma.
