Effectiveness of mogamulizumab in patients with Mycosis Fungoides or Sézary syndrome: A multicentre, retrospective, real-world French study.

BACKGROUND: Efficacy and safety of mogamulizumab, a monoclonal antibody directed against C-C chemokine receptor 4, were demonstrated in a previous multinational clinical trial conducted in patients with previously treated cutaneous T-cell lymphoma (CTCL): Sézary syndrome (SS) or Mycosis Fungoides (MF). OBJECTIVES: The real-world French OMEGA study aimed to describe effectiveness and tolerability of mogamulizumab in adult patients with CTCL, overall and according to the disease (SS or MF). METHODS: In this retrospective study, patients treated with mogamulizumab for SS or MF were included from 14 French expert centres. The overall response rate (ORR) under treatment was described (primary criterion), as well as treatment use and safety data. RESULTS: The 122 analysed patients (69 SS, 53 MF) were aged 66.6 ± 12.1 years at mogamulizumab initiation, and their median disease duration was 2.5 years (IQR: 1.3-5.6). Prior to treatment start, they received a median of three systemic CTCL therapies (2-5). Overall, 77.8% of patients suffered from advanced disease (Stage IIB-IVB), with frequent blood (B1/B2) involvement (67.5%). Over the treatment period (median: 4.6 months, 2.1-7.2), 96.7% of patients received all the planned mogamulizumab infusions. Among the 109 patients evaluable for effectiveness, ORR was 58.7% (95% CI [48.9-68.1]) overall, 69.5% [56.1-80.8] in SS and 46.0% [31.8-60.7] in MF. Compartmental response in the blood was observed in 81.8% [69.1-90.9] of SS patients. Skin responses were observed in 57.0% [47.0-66.5] of patients overall, 66.7% [52.9-78.6] in SS and 46.0% [31.8-60.7] in MF. The most common serious adverse drug reactions were rash (8.1% of patients) and infusion-related reactions (2.4%) which led to treatment discontinuation in 7.3% and 0.8% of patients, respectively. One patient with SS died from mogamulizumab-related tumour lysis syndrome. CONCLUSIONS: This large French study confirmed the effectiveness and tolerability of mogamulizumab in SS and MF patients in routine medical practice.

Recent advances on cutaneous lymphoma epidemiology.

BACKGROUND: Primary cutaneous lymphomas are a group of T- (CTCL) and B-cell (CBCL) malignancies. These diseases have different clinical presentations and prognosis. Our knowledge on their epidemiology is limited. Aim of this review was to summarize recent findings on the incidence of CTCL and CBCL, how they change over time, and to describe possible causes and consequences. We found that although there are important differences in the epidemiology of cutaneous lymphomas in different countries, the relative frequency of certain, especially rare lymphomas remains stable. Several studies described growing incidences of both CTCL and CBCL. The emergence of new diagnostic criteria, a more precise definition of the entities and new biomarkers enable a better classification of cases.

Actinic cheilitis: a systematic review of treatment options.

Actinic cheilitis is a premalignant condition that can progress to squamous cell carcinoma with a higher propensity for metastasis than cutaneous squamous cell carcinoma. Optimal treatment for actinic cheilitis has not been established, and evidence-based estimates of clinical cure in the dermatology literature are limited. Here, we review and synthesize outcome data published for patients with actinic cheilitis after treatment with various modalities. A systematic review was conducted in MEDLINE, Embase and the Cochrane library for English, French and German-language studies and references of included articles from inception to 20 January 2020. Studies were included if they reported on at least six patients with biopsy-proven actinic cheilitis. After quality appraisal, results of studies with the strongest methodology criteria were synthesized. 18 studies of 411 patients (published 1985 to 2016) were included. The majority of the studies were case series. Carbon dioxide laser ablation and vermilionectomy were associated with the most favourable outcomes with fewest recurrences. Chemical peel and photodynamic therapy were associated with higher recurrence. Adverse effects generally resolved in the weeks following treatment and cosmetic outcomes were favourable overall. In conclusion, there is a lack of high-quality comparative studies evaluating different treatment options for actinic cheilitis. The included publications used various outcome measures; however, the majority reported on the recently defined core outcome sets. These results suggest that both carbon dioxide laser ablation and vermilionectomy are effective treatments for actinic cheilitis. Prospective head-to-head studies are needed to compare these treatment modalities and to assess patient preferences.

The value of five blood markers in differentiating mycosis fungoides and Sézary syndrome: a validation cohort.

BACKGROUND: Clinical and histological diagnosis of Sézary syndrome (SS) and mycosis fungoides (MF) is challenging in clinical routine. OBJECTIVES: We investigated five blood markers previously described for SS (T-plastin, Twist, KIR3DL2, NKp46 and Tox) in a prospective validation cohort of patients. METHODS: We included 447 patients in this study and 107 patients were followed up for prognosis. The markers were analysed by reverse transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) on peripheral blood leucocytes and CD4+ T cells in a cohort of consecutive patients with early MF, erythrodermic MF and SS and compared with patients presenting with benign inflammatory dermatoses (BID) and erythrodermic BID. The markers were assessed in parallel to gold standard values such as CD4/CD8 ratio, loss of CD7 and CD26 membrane expression and CD4 absolute values. Sensitivity and specificity were analysed by receiver operator characteristic curves. The prognostic value of selected markers was analysed on a subset of patients. This study was conducted in one centre. RESULTS: We defined cut-off values for each marker. T-plastin, Twist and KIR3DL2 had the best validity. SS may be overrepresented. The combination of T-plastin and Twist was able to differentiate between erythrodermic MF or BID and SS. The additional analysis of KIR3DL2 may be useful to predict the prognosis. CONCLUSIONS: We propose T-plastin, Twist and KIR3DL2 measured by RT-qPCR as new diagnostic markers for Sézary syndrome.

Epidemiological changes in cutaneous lymphomas: an analysis of 8593 patients from the French Cutaneous Lymphoma Registry.

BACKGROUND: Primary cutaneous lymphomas (PCLs) are a heterogeneous group of T-cell (CTCL) and B-cell (CBCL) malignancies. Little is known about their epidemiology at initial presentation in Europe and about potential changes over time. OBJECTIVES: The aim of this retrospective study was to analyse the frequency of PCLs in the French Cutaneous Lymphoma Registry (GFELC) and to describe the demography of patients. METHODS: Patients with a centrally validated diagnosis of primary PCL, diagnosed between 2005 and 2019, were included. RESULTS: The calculated incidence was unprecedently high at 1·06 per 100 000 person-years. The number of included patients increased yearly. Most PCL subtypes were more frequent in male patients, diagnosed at a median age of 60 years. The relative frequency of rare CTCL remained stable, the proportion of classical mycosis fungoides (MF) decreased, and the frequency of its variants (e.g. folliculotropic MF) increased. Similar patterns were observed for CBCL; for example, the proportion of marginal-zone CBCL increased over time. CONCLUSIONS: Changes in PCL frequencies may be explained by the emergence of new diagnostic criteria and better description of the entities in the most recent PCL classification. Moreover, we propose that an algorithm should be developed to confirm the diagnosis of PCL by central validation of the cases.

[Intra-arterial procaine injection in peripheral arterial disease]. / Intraarterielle Procaingabe bei peripherer arterieller Verschlusskrankheit.

The report concerns a 61-year-old woman suffering from a chronic pain syndrome of peripheral arterial vascular disease. Despite level III-WHO medication she was not able to walk a distance of more than 100 m without pain. The patient received sonographically guided procaine injections into both femoral arteries. Directly after the injection the patient was free of pain for 4 weeks and for 6 months after a repeat injection.

[Herbal medicines for psychiatric disorders]. / Phytotherapie bei psychiatrischen Erkrankungen.

BACKGROUND: In Germany herbal medicines are traditionally frequently used. They represent an important therapeutic option, especially in self-medication. METHODS: Current systematic review articles and meta-analyses were evaluated and summarized with respect to the evidence of phytotherapeutic drugs for selected psychiatric indications. RESULTS: Apart from the use of St. John's wort for depression, no other herb has so far shown convincing evidence. CONCLUSION: Due to the promising effects and the low side effect potential within the existing studies, further randomized controlled trials (e. g. for Passiflora incarnata, Rhodiola rosea and Lavendula officinalis) are definitely indicated.

Does dietary fluid intake affect skin hydration in healthy humans? A systematic literature review.

BACKGROUND: Associations between daily amounts of drinking water and skin hydration and skin physiology receive increasingly attention in the daily life and in clinical practice. However, there is a lack of evidence of dermatological benefits from drinking increased amounts of water. MATERIALS AND METHODS: Pubmed and Web of Science were searched without any restrictions of publication dates. References of included papers and related reviews were checked. Eligibility criteria were primary intervention and observational studies investigating the effects of fluid intake on skin properties in English, German, Spanish or Portuguese language, including subjects being healthy and 18+ years. RESULTS: Searches resulted in 216 records, 23 articles were read in full text, and six were included. The mean age of the samples ranged from 24 to 56 years. Overall the evidence is weak in terms of quantity and methodological quality. Disregarding the methodological limitations a slight increase in stratum corneum and "deep" skin hydration was observed after additional water intake, particularly in individuals with lower prior water consumption. Reductions of clinical signs of dryness and roughness were observed. The extensibility and elasticity of the skin increased slightly. Unclear associations were shown between water intake and transepidermal water loss, sebum content, and skin surface pH. CONCLUSIONS: Additional dietary water intake may increase stratum corneum hydration. The underlying biological mechanism for this possible relationship is unknown. Whether this association also exists in aged subjects is unclear. Research is needed to answer the question whether increased fluid intake decreases signs of dry skin.

Evidence-based (S3) guideline for the treatment of androgenetic alopecia in women and in men - short version.

Androgenetic alopecia is the most common hair loss disorder, affecting both men and women. Initial signs of androgenetic alopecia usually develop during teenage years leading to progressive hair loss with a pattern distribution. Moreover, its frequency increases with age and affects up to 80% Caucasian men and 42% of women. Patients afflicted with androgenetic alopecia may undergo significant impairment of quality of life. The European Dermatology Forum (EDF) initiated a project to develop evidence-based guidelines for the treatment of androgenetic alopecia. Based on a systematic literature research the efficacy of the currently available therapeutic options was assessed and therapeutic recommendations were passed in a consensus conference. The purpose of the guideline is to provide dermatologists with an evidence-based tool for choosing an efficacious and safe therapy for patients with androgenetic alopecia.

Randomised clinical trial: yoga vs a low-FODMAP diet in patients with irritable bowel syndrome.

BACKGROUND: Irritable bowel syndrome is the most frequent gastrointestinal disorder. It is assumed that lifestyle interventions might be a rational treatment approach. AIM: To examine the effect of a yoga-based intervention vs a low-FODMAP diet on patients with irritable bowel syndrome. METHODS: Fifty-nine patients with irritable bowel syndrome undertook a single-blind, randomised controlled trial involving yoga or a low-FODMAP diet for 12 weeks. Patients in the yoga group received two sessions weekly, while patients in the low-FODMAP group received a total of three sessions of nutritional counselling. The primary outcome was a change in gastrointestinal symptoms (IBS-SSS). Secondary outcomes explored changes in quality of life (IBS-QOL), health (SF-36), perceived stress (CPSS, PSQ), body awareness (BAQ), body responsiveness (BRS) and safety of the interventions. Outcomes were examined in weeks 12 and 24 by assessors "blinded" to patients' group allocation. RESULTS: No statistically significant difference was found between the intervention groups, with regard to IBS-SSS score, at either 12 (Δ = 31.80; 95%CI = -11.90, 75.50; P = .151) or 24 weeks (Δ = 33.41; 95%CI = -4.21, 71.04; P = .081). Within-group comparisons showed statistically significant effects for yoga and low-FODMAP diet at both 12 and 24 weeks (all P < .001). Comparable within-group effects occurred for the other outcomes. One patient in each intervention group experienced serious adverse events (P = 1.00) and another, also in each group, experienced nonserious adverse events (P = 1.00). CONCLUSIONS: Patients with irritable bowel syndrome might benefit from yoga and a low-FODMAP diet, as both groups showed a reduction in gastrointestinal symptoms. More research on the underlying mechanisms of both interventions is warranted, as well as exploration of potential benefits from their combined use.

Randomised clinical trial: yoga vs written self-care advice for ulcerative colitis.

BACKGROUND: Perceived stress seems to be a risk factor for exacerbation of ulcerative colitis. Yoga has been shown to reduce perceived stress. AIMS: To assess the efficacy and safety of yoga for improving quality of life in patients with ulcerative colitis. METHODS: A total of 77 patients (75% women; 45.5 ± 11.9 years) with ulcerative colitis in clinical remission but impaired quality of life were randomly assigned to yoga (12 supervised weekly sessions of 90 min; n = 39) or written self-care advice (n = 38). Primary outcome was disease-specific quality of life (Inflammatory Bowel Disease Questionnaire). Secondary outcomes included disease activity (Rachmilewitz clinical activity index) and safety. Outcomes were assessed at weeks 12 and 24 by blinded outcome assessors. RESULTS: The yoga group had significantly higher disease-specific quality of life compared to the self-care group after 12 weeks (Δ = 14.6; 95% confidence interval=2.6-26.7; P = 0.018) and after 24 weeks (Δ = 16.4; 95% confidence interval=2.5-30.3; P = 0.022). Twenty-one and 12 patients in the yoga group and in the self-care group, respectively, reached a clinical relevant increase in quality of life at week 12 (P = 0.048); and 27 and 17 patients at week 24 (P = 0.030). Disease activity was lower in the yoga group compared to the self-care group after 24 weeks (Δ = -1.2; 95% confidence interval=-0.1-[-2.3]; P = 0.029). Three and one patient in the yoga group and in the self-care group, respectively, experienced serious adverse events (P = 0.317); and seven and eight patients experienced nonserious adverse events (P = 0.731). CONCLUSIONS: Yoga can be considered as a safe and effective ancillary intervention for patients with ulcerative colitis and impaired quality of life. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02043600.

Continuous time of flight measurements in a Lissajous configuration.

Short pulses used by traditional time-of-flight mass spectrometers limit their duty cycle, pose space-charge issues, and require high speed detectors and electronics. The motivation behind the invention of continuous time of flight mass spectrometers was to mitigate these problems, by increasing the number of ions reaching the detector and eliminating the need for fast data acquisition systems. The most crucial components of these spectrometers are their modulators: they determine both the maximal modulation frequency and the modulation depth. Through these parameters they limit the achievable mass resolution and signal-to-noise ratio. In this paper, a new kind of setup is presented which modulates the beam by deflecting it in two perpendicular directions and collects ions on a position sensitive detector. Such an Lissajous time of flight spectrometer achieves modulation without the use of slits or apertures, making it possible for all ions to reach the detector, thereby increasing the transmission and signal-to-noise ratio. In this paper, we provide the mathematical description of the system, discuss its properties, and present a practical demonstration of the principle.

Sensitivity to change of the Dermatology Life Quality Index in adult females with facial acne vulgaris: a validation study.

BACKGROUND: The postadolescent form of acne papulopustulosa, also referred to as 'acne tarda' can have substantial negative impact on Quality of Life, especially in adult female patients. OBJECTIVE: Although the Dermatology Life Quality Index (DLQI) is widely used, empirical evidence about its performance in adult female acne patients is lacking. METHODS: In this prospective cohort study, we have investigated the sensitivity to change of the DLQI in 53 female adult acne patients with mild to moderate facial acne treated with azelaic acid (AzA) 15% gel twice daily over 24 weeks. RESULTS: Mean Investigator Static Global Assessment (ISGA) score was 2.3 (SD 0.5) at baseline and ranged from 0.9 (SD 0.3) to 2.1 (SD 0.4) at the end of the study in the 'Highly Improved' and 'Unchanged' responder groups respectively. The mean baseline DLQI score was 5.1 (SD 4.2). The Effect Size in the responder group 'Highly Improved' was 0.66; in group 'Improved' 0.62 and 0.23 in group 'Unchanged'. At the end of study, the mean DLQI score ranged from 1.1 (SD 1.5) in the 'Highly Improved' group to 3.7 (SD 6.0) in the 'Unchanged' group. CONCLUSION: The results support the sensitivity to change of the DLQI in this population.

Effects of two different fabrics on skin barrier function under real pressure conditions.

BACKGROUND: Pressure Ulcers (PUs) are a severe form of skin and soft tissue lesions, caused by sustained deformation. PU development is complex and depends on different factors. Skin structure and function change during prolonged loading on PU predilection sites and surfaces being in direct contact with skin are likely to have an impact as well. Little is known about the influence of fabrics on skin function under pressure conditions. OBJECTIVES: To investigate skin responses to sustained loading in a sitting position and possible differences between two fabrics. METHODS: Under controlled conditions 6 healthy females (median age 65.0 (61.0-67.8) years) followed a standardized immobilization protocol of a sitting position for 45 min on a spacer and on a cotton fabric. Before and after the loading period skin surface temperature, stratum corneum hydration, transepidermal water loss (TEWL), erythema, skin elasticity and 'relative elastic recovery' were measured at the gluteal areas. RESULTS: A 45 min sitting period caused increases of skin surface temperature and erythema independent of the fabric. Loading on spacer fabric showed a two times higher increase of TEWL compared to cotton. Stratum corneum hydration showed slight changes after loading, skin elasticity and 'relative elastic recovery' remained stable. CONCLUSIONS: Sitting on a hard surface causes skin barrier changes at the gluteal skin in terms of stratum corneum hydration and TEWL. These changes are influenced by the fabric which is in direct contact to the skin. There seems to be a dynamic interaction between skin and fabric properties especially in terms of temperature and humidity accumulation and transport.

A Review of Integrative Medicine in Gynaecological Oncology.

In recent years complementary and alternative medicine (CAM) has increasingly been the focus of international research. Numerous subsidised trials (7903) and systematic reviews (651) have been published, and the evidence is starting to be integrated into treatment guidelines. However, due to insufficient evidence and/or insufficient good quality evidence, this has mostly not translated to practice recommendations in reviews by the Cochrane collaboration gynaecology group. There is nevertheless a not insignificant number of CAM providers and users. The percentage of oncology patients who use CAM varies between 5 and 90 %. Doctors have been identified as the main providers of CAM. Half of gynaecologists offer CAM because of personal conviction or on suggestion from colleagues. This must be viewed in a critical light, since CAM is mostly practiced without appropriate training, often without sufficient evidence for a given method - and where evidence exists, practice guidelines are lacking - and lack of safety or efficacy testing. The combination of patient demand and lucrativeness for doctors/alternative medicine practitioners, both based on supposed effectiveness CAM, often leads to its indiscriminate use with uncertain outcomes and significant cost for patients. On the other hand there is published, positive level I evidence for a number of CAM treatment forms. The aim of this article is therefore to review the available evidence for CAM in gynaecological oncology practice. The continued need for research is highlighted, as is the need to integrate practices supported by good evidence into conventional gynaecological oncology.

Follicular fluorescence quantity to characterize acne severity: a validation study.

BACKGROUND: Porphyrins are native fluorophores in the follicle openings, visible under ultraviolet-A light. Acne severity might be associated with increased Propionibacterium acnes colonization and porphyrin production. Aim of this study was to investigate whether the parameter fluorescence quantity can be used to measure acne severity. METHODS: A validation study was conducted in 24 patients with acne using split-face design. Acne severity was measured using Investigator Static Global Assessment scores and lesion counts. Reliability, construct validity and sensitivity to change in fluorescence quantity were investigated. RESULTS: Mean baseline Investigator Static Global Assessment score was 2.7 (SD 0.1). Mean baseline fluorescence quantities were 24.8 (SD 4.0) on the cheek and 20.3 (SD 4.6) on the chin. On day 25, values ranged from 6.0 (SD 6.0) to 18.1 (SD 18.4) on the cheek and from 2.6 (SD 4.4) to 14.7 (SD 16.2) on the chin. The intraclass correlation coefficients of fluorescence quantity ranged from 0.513 to 0.987. Effect sizes for fluorescence measurements were highest on the chin and cheek ranging from 0.24 to 0.77 and 0.32 to 0.75, respectively. CONCLUSION: Fluorescence quantity indicates acne severity, especially on the inner cheek and chin areas. Fluorescence quantity is reliable but is not as sensitive as manual lesion counting.
