Acute Renal Failure and Silent Myocardial Infarction Following Multiple Honey Bee Stings.

Massive envenomation by honey bee sting is capable of causing multiorgan dysfunction as a result of direct toxic effect of venom and secondary to systemic anaphylactic reactions. Myocardial infarction (MI) due to honey bee sting is rare, so is acute renal failure (ARF). The probable mechanism is severe coronary arterial spasm with secondary in situ thrombosis as a result of systemic anaphylaxis. This is a case of Kounis syndrome, which is the concurrence of acute coronary syndromes with conditions associated with mast cell activation. We describe a case of ARF and MI in a 58-year-old man after multiple honey bee stings; clinically silent and detected on electrocardiography and by cardiac biomarkers.

Anton’s Syndrome and Cortical Blindness.

Introduction: Anton’s syndrome is a condition where the patient is unaware of being blind and denies the problem even when it is pointed out to him. On the contrary, in cortical blindness patient is aware of his blindness and does not deny it. In both, bilateral lesions of the occipital lobes are seen. Case presentation: We present two cases of cortical blindness, Case 1 being consistent with diagnosis of Anton’s syndrome where patient denied of her blindness. Both cases revealed bilateral occipital lobe infarcts. Conclusions: Cerebrovascular disease is the most common cause of cortical blindness. These occur as a result of successive infarctions as seen in Case 1 or from a single embolic or thrombotic occlusion as seen in Case 2. First case is Anton’s syndrome with patient denying blindness, whereas second case is cortical blindness. It is due to involvement of other cortical centers in Anton’s syndrome that patient denies blindness.
