Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) are two distinct designations for a rare dermal sarcoma entity. These tumors arise predominantly in the sun-damaged skin of elderly patients. Although both AFX and PDS have a similar clinical presentation and nearly identical genetic features, they significantly differ in prognosis.

- Bioabsorbable implants, especially metal alloys like zinc and magnesium, are being researched as potential future materials for bone healing due to their compatible mechanical properties and no long-term side effects.
- Recent studies showed that new bioabsorbable zinc (Zn-6Ag) and magnesium pins have comparable mechanical support to traditional implants like K-wires and cancellous bone screws in bone-implant connections.
- Specifically, during loading experiments, the zinc pin demonstrated better shear strength than K-wires and matched the shear strength of magnesium pins already used in clinical settings.
Zinc alloys have recently been researched intensely for their great properties as bioabsorbable implants for osteosynthesis. Pure zinc (Zn) itself has relatively poor strength, which makes it insufficient for most clinical use. Research has already proven that the mechanical strength of zinc can be enhanced significantly by alloying it with silver.
