Acute coronary syndrome or ST-elevation myocardial infarction that develops as a hypersensitive reaction following exposure to an allergen, such as chemicals or bee or wasp stings, is known as Kounis syndrome (KS). Based on angiographic characteristics, three kinds of KS have been identified. Multiple bee stings typically result in localized allergic reactions and anaphylaxis, but they can also occasionally induce severe systemic toxic reactions. Here, a case of KS in a 50-year-old male presented with swelling on the face and upper limbs and breathing difficulties resulting from bee stings which led to myocardial infarction. The risk of KS should be considered by the physician at the primary level in all situations involving multiple bee bites., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Borkar et al.)

Background: To date, only 25 cases of cerebral infarction following a bee or wasp sting have been reported. Due to its rarity, undefined pathogenesis, and unique clinical features, we report a case of a 62-year-old man with progressive cerebral infarction following bee stings, possibly related to vasospasm. Furthermore, we review relevant literature on stroke following bee or wasp stings., Case Presentation: A 62-year-old retired male presented with progressive ischemic stroke after bee stings to the ear and face. Initial magnetic resonance imaging of the brain showed small punctate infarcts in the left medulla oblongata. Head and neck computed tomography angiography showed significant stenosis in the basilar artery and occlusion in the left V4 vertebral artery. The patient received intravenous alteplase (0.9 mg/kg) without symptomatic improvement. Digital subtraction angiography later demonstrated additional near occlusion in the left posterior cerebral artery (PCA). Thrombectomy was considered initially but was aborted due to hemodynamic instability. Repeated CT brain after 24 h showed acute infarcts in the left parieto-occipital region and left thalamus. The near occluded PCA was found to be patent again on magnetic resonance angiography (MRA) 25 days later. This reversibility suggests that vasospasm may have been the underlying mechanism. Unfortunately, the patient had persistent significant neurological deficits after rehabilitation one year later., Conclusion: Cerebral infarction following bee stings is rare. There are several proposed pathophysiological mechanisms. While the natural course of this phenomenon is not well characterized, early diagnosis and treatment are essential. Furthermore, it is important to establish standardized care procedures for this unique entity., Competing Interests: Conflict of interest: Authors state no conflict of interest., (© 2022 Shuiquan Yang et al., published by De Gruyter.)

Anaphylactic shock is an unexpected, life-threatening, and sometimes fatal occurrence that affects patients in 75% of instances without a prior history of allergies. The severity of the reaction can vary among individuals. We report a case who died suddenly after being stung by bees in various parts of his body., Competing Interests: The authors confirm that this article content has no conflict of interest., (© 2022 The Authors.

Usually, bee sting systemic envenomation is self-limited mild allergic reaction rarely associated with systemic manifestations such as anaphylaxis, myocardial injury, encephalitis, acute kidney injury and serum sickness. Kounis syndrome also known as allergic myocardial infarction is uncommon clinical feature and reported cases are scarce in literature. Herein, we described a hypothetical case of Kounis syndrome diagnosed in a 74-year-old man initially presenting for anaphylactic reaction., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Envenoming syndrome is an uncommon condition associated with significant morbidity and mortality following multiple Hymenoptera stings. We review the case of a 90-year-old male who presented after receiving greater than 100 bee stings and was found to have rhabdomyolysis with concomitant acute kidney injury. Physicians should consider envenoming syndrome in all patients presenting with greater than 50 bee stings, despite hemodynamically stability upon initial presentation., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Constantino et al.)

The findings of massive Africanized honeybee stings in two hair sheep and a mare are reported. One sheep died 15 h after attack, and the survivors developed skin necrosis on the sting sites. Pathological evaluation revealed necrosis in the dermis, degeneration of the tubular epithelial cells, and multifocal hemorrhages in heart and spleen. The massive attack by Africanized honeybees induced lesions in the skin, heart, muscles, kidneys, and lungs., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interest., (Copyright © 2020 Elsevier Ltd.

Bee stings are commonly encountered worldwide. Various manifestations after bee sting have been described including local reactions which are common, systemic responses such as anaphylaxis, diffuse intravascular coagulation and hemolysis. We report a case of a 74-year-old man who developed neurologic deficit 5 hours after bee stings, which was confirmed to be left frontal infarction on brain CT-scan. The case does not follow the reported  pattern  of hypovolemic or anaphylactic shock, hemolysis and/or  rhabdomyolysis, despite the potentially lethal amount of venom injected. Diverse mechanisms have been proposed to give an explanation to all the clinical manifestation of both toxic and allergic reactions secondary to bee stings. Currently, the most accepted one state that victims can develop severe syndrome characterized by the release of a large amount of cytokines.
