Article Abstract
Ibrutinib, a first-class Bruton tyrosine kinase inhibitor, is known to be associated with adverse bleeding events and has been recently approved for the treatment of relapse Waldenström macroglobulinemia (WM). Here, we report the exhaustive clinical and biological follow-up of 2 patients treated by ibrutinib alone in the context of relapsed WM with an acquired von Willebrand syndrome (AVWS) complication. In two cases, ibrutinib has been shown to be quickly efficient and safe for treating both AVWS and its underlying condition the WM, without bleeding complications. Interestingly, ibrutinib treatment brings a rapid and extended over time normalization of von Willebrand factor clearance. These observations show that ibrutinib is a valuable therapeutic option in relapsed WM patients associated with AVWS and highlighting the need for further cohort studies with long-term follow-up of patients to confirm the efficacy and safety of a treatment by ibrutinib for WM patients with AVWS complication.

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine malignancy of the skin. The cell of origin of MCC is thus far unknown and proposed cells of origin include Merkel cells, pro-/pre- or pre-B cells, epithelial stem cells, and dermal stem cells. In this study, we aimed to shed further light on the possibility that a subset of MCC tumors arise from epithelial stem cells of the skin by examining the expression of hair follicle and epidermal stem cell markers in MCC and normal human skin.

Article Synopsis
- - Trichothiodystrophy is a rare genetic disorder characterized by abnormal hair development and affects multiple body systems; this study focuses on two Finnish families with this condition.
- - The researchers identified a new mutation in the MPLKIP gene through whole-exome sequencing, confirming the diagnosis of non-photosensitive trichothiodystrophy type 4 (TTD4) in three patients.
- - This report enhances understanding of TTD4 by detailing the patients' unique physical traits and comparing their clinical features with previously documented cases.

Article Synopsis
- A study looked at a treatment called L4-DRG stimulation for patients with a painful condition called CRPS.
- The researchers tested how patients felt different sensations like pain and touch before and after 3 months of treatment.
- They found that the treatment helped reduce pain for the patients, but it did not change how they felt warmth or touch.

Article Synopsis
- Increased expression of PDGF and VEGF is linked to chronic rejection in kidney transplants, which can lead to allograft loss.
- Sunitinib, a tyrosine kinase inhibitor, was tested in a rat model and shown to significantly reduce neointimal formation, smooth muscle cell activity, and chronic rejection signs while improving kidney function.
- The findings suggest that targeting both PDGF and VEGF with sunitinib may offer a promising new approach for preventing chronic rejection in kidney transplant patients.
