Palm oil-based wax is a waste material from palm oil refining process. Recent prototyping
activities have used industrial blue wax or synthetic wax to produce prototype parts by machining
processes. The new palm oil-based wax blended with LLDPE reduces the use of synthetic wax for
engineering applications. This paper studies the machining characteristic of two different composite
blends: LLDPE/PALMAC 95 -16 Palm Oil-Based Wax and LLDPE/PALMAC 98-18 Palm Oil-Based
Wax. Three machining characteristic results were recorded, namely; surface roughness, temperature
and dimensional consistency.
Immune Thrombocytopenia Purpura (ITP) secondary to vaccinations is rare, especially after autologous hematopoietic stem cell transplantation (HSCT). A 31-yearold female received autologous HSCT for relapsed Hodgkin Disease, with platelet engraftment at Day+14. One week after receiving second scheduled vaccinations, she developed severe thrombocytopenia (3x109/L) associated with pharyngeal hematoma. Bone marrow (BM) examinations were consistent with ITP, possibly secondary to Influenza vaccine. Platelet increment was poor despite high dose corticosteroids, intravenous immunoglobulin (IVIG), Danazol and Eltrombopag. A repeated BM biopsy was in agreement with ITP. Re-treatment with tapering doses of prednisolone resulted in stable platelet counts at 120x109/L a year later.
