Von Willebrand disease (VWD) is the most common inherited bleeding disorder in the world. The spectrum of VWD spans quantitative and qualitative deficiencies of von Willebrand factor (VWF), a platelet adhesive protein. It manifests primarily as mucocutaneous bleeding, but severely affected patients may suffer soft tissue bleeding and hemarthroses. There is disagreement in the multiple guidelines published regarding diagnosis, especially of type 1 VWD, which also remains the most opaque with respect to molecular characterization. Treatment with desmopressin (DDAVP) is most effective in type 1 VWD, but regimens are not standardized. It is not clear which type 2 VWD patients with qualitative deficiencies can be treated with DDAVP and which ones should receive VWF concentrates. No guidelines stipulate which patients might benefit from prophylactic VWF infusions and how they should be dosed. These are some current controversies in VWD that are discussed in this review.

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.
