The mirror self-recognition (MSR) is a behavioral technique to determine whether an animal has the ability to
identify themselves in front of a mirror. A Malayan sun bear (Helarctos malayanus) was selected from Zoo Negara
Malaysia and an acrylic mirror is placed outside of the cage to observe interaction of the animal to the mirror. This
study showed that the bear’s behaviour was inconsistent due to the inability of the animal to recognize its own
reflection after exposure to the close and open mirror tests. These results suggest that when keeping Malayan sun bears
in captivity, putting a mirror as enrichment may promote communication and familiarity between conspecific.
Patients with myelodysplastic syndrome (MDS) often need platelet transfusions to address thrombocytopenia. The risk of alloimmunization, particularly in Rhesus (Rh) incompatibility between donors and recipients during platelet transfusions, is heightened, especially with whole blood-derived pooled platelets as opposed to apheresis platelets. Although the occurrence of alloimmunization from platelet transfusions is minimal, there is an ongoing debate about whether Rh immune globulin (RhIg) should be administered to Rhesus D (RhD)-negative recipients of RhD-positive platelet units. We present a unique case of anti-D alloimmunization in a 56-year-old patient with underlying MDS following multiple platelet transfusions but never received packed cell transfusion or anti-D immunoglobulin. Some studies advocate for RhIg administration in specific scenarios and for certain patient populations. This case underscores the importance of considering Rhesus compatibility or administering anti-D immunoglobulin in cases where frequent platelet transfusions are required.
