Efficacy of Biologics Targeting Tumour Necrosis Factor-alpha, Interleukin-17 -12/23, -23 and Small Molecules Targeting JAK and PDE4 in the Treatment of Nail Psoriasis: A Network Meta-analysis.

The comparative efficacy of registered anti-psoriatic biologics and small molecules in treating nail symptoms has not been systematically evaluated. The aim of this study was to perform a network meta-analysis to determine the efficacy of biologics and small mole-cules in nail psoriasis. A Bayesian network meta- analysis of 17 randomized clinical trials (a total of 6,053 nail psoriatic patients) was performed, comparing the short-term (week 10-16) efficacy of biologics and small molecules in the treatment of nail psoriasis. All active treatments were found to be superior to place-bo. Ixekizumab 80 mg every 4 weeks (Nail Psoriasis Severity Index (NAPSI) % improvement, Surface Under the Cumulative Ranking (SUCRA)=0.92) and etanercept 50 mg twice weekly (probability of achiev-ing NAPSI 50, SUCRA=0.82) proved the best short-term treatment options. However, efficacy end-points in psoriasis trials were not optimized for nail assessment, and outcome parameters were highly heterogeneous, limiting comparability. In conclusion, outcome parameters and efficacy endpoints of nail psoriasis trials should be standardized.

[Dermoscopy of inflammatory skin diseases]. / Dermatoskopie entzündlicher Hauterkrankungen.

The dermoscope was initially used in dermatology to distinguish between pigmented and nonpigmented tumors, both benign and malignant. Over the last two decades, however, the spectrum of dermoscopy has broadened and its role in the diagnosis of nonneoplastic diseases, in particular inflammatory skin diseases, has become increasingly important. In the diagnosis of general and inflammatory skin diseases, it is recommended that dermoscopic evaluation should be performed after clinical examination. In the following summary, the dermoscopic features of the most common inflammatory skin diseases are described. Among the detailed parameters are the vascular structures, color, scaling, follicular findings, and specific signs associated with each disease.

Comparison of the Objective Severity and the Esthetic Perception of Nail Symptoms in Psoriasis.

Introduction: Nail changes are frequent in psoriasis, and the negative impact of nail psoriasis on patients' quality of life is well known. No data are available however about the association of the objective severity of nail psoriasis and the subjective perception of these symptoms. The purpose of this study was to determine the correlation between the severity of psoriatic nail changes (as determined by the Nail Psoriasis Severity Index [NAPSI]) and the esthetic assessment of nail psoriasis. Methods: Participants (general population and psoriasis patients) were asked to rate 19 nail images (including psoriatic and healthy nails) on a 0-10 scale, based on how disturbing they considered them esthetically. Objective severity (NAPSI) scores of nails were compared to the subjective evaluation values. Results: Nail symptom severity correlated well with the subjective scores. However, while nails with low (0) and high (6-8) NAPSI values received consistent subjective scores, the esthetic perception of nails with moderate NAPSI scores was rather heterogeneous. The age of the respondents showed robust positive correlation with the subjective assessment of nail symptoms both within the psoriatic and the general population. Discussion: Gender, the presence of psoriasis, or medical education had no significant influence on the esthetic assessment of psoriatic nail changes.

Minor Physical Anomalies in Bipolar Disorder-A Meta-Analysis.

Introduction: Minor physical anomalies (MPAs) may reflect basic neurobiological features underlying bipolar disorders (BPD), as they are sensitive physical indicators of morphogenetic failure of the brain. Despite several researches about the presence of MPAs in BPD, the results are still controversial. Objectives: The aim of the present meta-analysis was to assess the standardized weighted mean effect sizes of MPAs in BPD and to examine if MPAs may be found predominantly in the head and/or facial regions in BPD patients compared to controls (HC). Methods: Four studies, involving 155 patients with BPD, and 187 HC, were involved in the analysis after searching the literature. For the investigation of MPAs in the peripheral (MPA-P) and in the head and facial regions (MPA-CF), two studies involving 121 BPD patients, and 133 HC passed the inclusion criteria. Results: The number of the MPAs in the BPD group was significantly higher compared to HC. Another important finding of the present study is that BPD patients' MPA-P scores do not significantly differ from those of the HC. In contrast, BPD patients' MPA-CF scores were found to be significantly higher compared to HC subjects. It is important to note that there was a low number of eligible publications included, which caused higher heterogeneity. Conclusions: Low quality of evidence suggests that MPAs are more common in patients with BPD than in HC and the higher rate of MPAs is found predominantly in the head and facial regions.
