- Sezary syndrome (SS) is an aggressive leukemic variant of cutaneous T-cell lymphoma (CTCL) with a median life expectancy of less than 4 years. Although initial treatment responses are often good, the vast majority of patients with SS fail to respond to ongoing therapy. We hypothesize that malignant T cells are highly heterogeneous and harbor subpopulations of SS cells that are both sensitive and resistant to treatment. Here, we investigate the presence of single-cell heterogeneity and resistance to histone deacetylase inhibitors (HDACi) within primary malignant T cells from patients with SS. Using single-cell RNA sequencing and flow cytometry, we find that malignant T cells from all investigated patients with SS display a high degree of single-cell heterogeneity at both the mRNA and protein levels. We show that this heterogeneity divides the malignant cells into distinct subpopulations that can be isolated by their expression of different surface antigens. Finally, we show that treatment with HDACi (suberanilohydroxamic acid and romidepsin) selectively eliminates some subpopulations while leaving other subpopulations largely unaffected. In conclusion, we show that patients with SS display a high degree of single-cell heterogeneity within the malignant T-cell population, and that distinct subpopulations of malignant T cells carry HDACi resistance. Our data point to the importance of understanding the heterogeneous nature of malignant SS cells in each individual patient to design combinational and new therapies to counter drug resistance and treatment failure.

- Firmly established as the leading international reference in this field, Non-Invasive Methods and the Skin broke new ground with its comprehensive coverage of methods used in both clinical and experimental dermatology. Completely revised and updated, containing more than twice as much information, the Second Edition continues the tradition. The authors' thorough research and clear organization make this book a baseline reference for those using noninvasive biophysical methods to study the skin. Arranged by physical modality and structured to provide educational and practical information, the second edition, like its predecessor, will prove to be of value to young researchers and senior scientists alike. The coverage of major evaluation and measurement methods share a consistent format, including scope, sources of error, application, and validity. This edition incorporates 69 revised chapters with more than 90 new chapters covering topics such as computer technique, imaging techniques, skin friction, barrier functions, and more.New chapters provide coverage of: computers, computer techniques, and image analysis imaging techniques, including clinical photography legal situations and guidelines behind instrumental use skin friction barrier functions important new techniques such as in vitro confocal microscopy, OCT, and Raman spectroscopy veterinary/animal research use of methods The truly interdisciplinary, international panel of contributors includes experts from the specialties of dermatology, bioengineering, pathology, manufacturing engineering, medical physics, pharmacology, microbiology, neurology, surgery, obstetrics and gynecology, cardiovascular research, and pharmacy from academic institutions and hospitals in countries such as Denmark, Germany, the United Kingdom, the United States, Japan, Israel, Taiwan, and Singapore. The revision is extensive and covers a broad spectrum of methods while providing the same caliber of authoritative information that made the previous edition so popular. Application oriented, practical, and instructive, this Second Edition will meet the needs of the researchers today, and in years to come.

Tidskriftsartikel (refereegranskat)abstract
- Mohs Micrographic Surgery (MMS) is a treatment option for high-risk facial nonmelanoma skin cancer with high cure rates. Especially on the nasal tip, the tissue sparing properties of MMS are appealing. The nasal tip is a common location of nonmelanoma skin cancer and can be a challenging anatomical structure for reconstructive surgery due to its prominent location in the face, the shortage of spare tissue, as well as the stiffness and composition of different skin types, cartilage and bone.The aim of the present paper is to review and demonstrate how reconstruction of the nasal tip can be done successfully to improve the care for patients undergoing MMS in this area.Using selected literature on the area and the surgeons experience, each method of repair are described including their individual advantages and challenges. Pictures and consent were selected from one patient who underwent each repair method and three photos are presented in this paper: one after tumor resection, one immediately after repair, and one minimum 6 months post-surgery.We present eight surgical methods as well as pictures from previous surgeries.The results demonstrate obtainable results using very different surgical methods and the importance of an individualized approach to repairing cutaneous defects of the nasal tip.
