Abstract
Pseudoxanthoma elasticum (PXE) is an autosomal recessive metabolic disorder characterized by ectopic mineralization of soft connective tissue. Histopathology findings include fragmented, mineralized elastic fibers and calcium deposits in the mid-dermis. Nonlinear microscopy (NLM) can be used for visualization of these histopathological alterations of the mid-dermis in PXE-affected skin sections. Upon introducing a normalized 3D color vector representation of emission spectra of three of the main tissue components (collagen, elastin and calcification) we found that due to their broad, overlapping emission spectra, spectral separation of emission from elastin and calcification is practically impossible in fresh-frozen or unstained, deparaffinized PXE sections. However, we found that the application of a low concentration Phloxine B staining after the deparaffinization process creates an imaging contrast for these two tissue components, which enables spectral decomposition of their fluorescence images. The obtained concentration maps for calcium deposits can be well suited for the determination of illness severity by quantitative analysis.

Abstract
BACKGROUND Numerous generic, skin- and disease-specific health-related quality of life (HRQoL) measures are available for patients with hidradenitis suppurativa (HS). Yet, robust psychometric evidence is lacking in many aspects of these outcome measures. OBJECTIVES We sought to determine convergent and known-groups validity of multiple generic and skin-specific HRQoL measures and to identify predictors of impaired HRQoL in patients with HS. METHODS Between 2017 and 2019, a multicentre cross-sectional study was carried out involving 200 consecutive HS patients. HRQoL outcomes included the EQ-5D-5L, EQ visual analogue scale (EQ VAS), Skindex-16, Dermatology Life Quality Index (DLQI) and DLQI-Relevant (DLQI-R). Disease severity was graded by HS-Physician's Global Assessment (HS-PGA) scale and the Modified Sartorius scale (MSS). RESULTS Overall, 77%, 56%, 51%, 46% and 28% reported problems in the pain/discomfort, usual activities, anxiety/depression, mobility and self-care dimensions of EQ-5D-5L. Mean ± SD EQ VAS, DLQI and DLQI-R scores were 64.29 ± 22.68, 11.75 ± 8.11 and 12.19 ± 8.33, respectively. Skindex-16 responses indicated that the emotional burden of HS (64.55 ± 29.28) far exceeded those of functioning (49.40 ± 34.70) and physical symptoms (46.74 ± 29.36). EQ-5D-5L, EQ VAS, DLQI, DLQI-R and Skindex-16 total scores had moderate or strong correlations with each other (range: |0.487| to |0.993|), weak or moderate correlations with HS-PGA (|0.350| to |0.433|) and weak correlations with MSS (|0.324| to |0.389|). DLQI-R slightly outperformed DLQI both in terms of convergent and known-groups validity. Being female, lower education level, more severe disease and genital involvement were associated with worse HRQoL (P < 0.05). CONCLUSION This study provides high-quality evidence that among skin-specific outcomes, the DLQI, DLQI-R and Skindex-16, and among generic instruments, the EQ-5D-5L are suitable to be used in HS patients. In future research, we recommend the use of existing well-validated HRQoL tools instead of developing new measures for each study. The development of composite measures that combine physician- and patient-reported outcomes is not supported by evidence in HS.

Abstract
BACKGROUND No systematic review has yet evaluated the available evidence on health-related quality of life (HRQOL) in alopecia areata (AA). OBJECTIVES To conduct a systematic review and meta-analysis of HRQOL studies among patients diagnosed with AA. METHODS A systematic search was performed for papers published between 1946 and 15 December 2014 in Medline, Embase, Web of Science, CINAHL, PsycINFO and the Cochrane Library. Random-effects meta-analyses were conducted to pool data. RESULTS Twenty-one studies were included, representing a total of 2530 adult patients with AA. Of the 14 different HRQOL measures used in the studies, Dermatology Life Quality Index (DLQI; n = 8) and SF-36 (n = 7) were the most common. Three AA-specific HRQOL instruments were identified: Alopecia Areata Quality of Life Index, Alopecia Areata Quality of Life and Alopecia Areata Symptom Impact Scale. The mean pooled DLQI score of patients with AA was 6·3 (95% confidence interval 5·6-7·1). Comparing age- and sex-matched controls, the meta-analysis of SF-36 studies revealed significantly reduced HRQOL across the role-emotional, mental health and vitality domains (P < 0·001). Wearing a wig had a positive impact, while scalp involvement, anxiety and depression had a negative impact on HRQOL. Conflicting results were found regarding the association between HRQOL and age, sex, marital status and disease duration. CONCLUSIONS Patients with AA experience significant impairment in HRQOL, especially in the area of mental health. Several generic and dermatology-specific HRQOL instruments have been used, but no validation studies have confirmed their applicability in AA. The newly developed AA-specific measures seem very promising; however, a more extensive assessment of validity and reliability is needed.

Abstract
Nuclei isolated from higher eukaryotic cell lines were directly analyzed by field inversion gel electrophoresis. Brief incubation of nuclei with ionic detergents yielded a single band between 50-100 kb. The apparent fragment size decreased to approximately equal to 50 kb after proteinase digestion. The latter treatment alone induced less regular, less than or equal to 50 kb fragmentation. DNA extracted from detergent and proteinase-treated nuclei also appeared in a band of about 40 kb. Embedding into agarose plugs did not protect nuclei, as opposed to cells, from detergent-induced fragmentation. The phenomenon is strikingly analogous to the double-strand DNA cleavage reactions mediated by topoisomerase II. Our data are compatible with any of the following interpretations: 1.) regularly spaced protein bridges, probably involving topoisomerase II, maintain or control continuity of chromosomal DNA in certain states of higher eukaryotic cells. 2.) The DNA might become accessible to a putative endonuclease at regularly spaced sites upon detergent treatment of isolated nuclei.
