“…Rapid aberrant eye movements are likely to be more frequent during envenoming by Centruroides , found in North and Central America. Movements are bilateral and symmetrical, horizontal or rotary, suggesting a peripheral origin, which some authors have attributed to cerebral edema, potentially due to vasoconstriction of brain capillaries, including those in the thalamus 34. The convulsive forms sometimes attributed to hyperthermia and dehydration in very young children could be of the same origin.…”

Scorpion stings are common in many tropical countries. Although most scorpion stings cause only localized pain without life-threatening envenoming, about one third of stings cause systemic envenoming which can result in death. Children are particularly sensitive to scorpion envenoming. The severity of scorpion stings is related to the presence of neurotoxins in the venom that cause a sudden release of neurotransmitters from the autonomic nervous system, predominantly sympathetic. There is also a strong inflammatory response that worsens symptoms, including those of a respiratory nature. Several vital functions may be directly affected, including the cardiovascular, respiratory, and neuromuscular systems. Hypertension is constant at the beginning of systemic envenoming and sometimes has a severe cardiac and respiratory impact. Although controversial, immunotherapy is the only etiological treatment. Administered early, it prevents many complications and improves the outcome. New antivenoms are highly purified immunoglobulin fragments, the efficacy and safety of which are excellent. As a consequence, adverse reactions to antivenoms are now very rare and usually mild, which should limit any reluctance regarding their routine use. Symptomatic treatment is still necessary to support immunotherapy, especially in cases of delayed arrival at hospital. A combination of both approaches should be considered, based on local resources and constraints.

“…An increase in blood pressure secondary to sympathetic stimulation is also mentioned, which could cause hemorrhages, brain edema and cerebral infarction. [10] The acute dyspnea on the night of scorpion sting could have been due to pul==monary edema. The associated hypotension possibly precipitated the cerebral ischemia in the already compromised carotid circulation due to vasospasm.…”

Scorpion sting is common in villages, and is an important public health problem in India. The clinical symptoms of envenomation by scorpion sting are by sympathetic and parasympathetic stimulation, causing a variety of symptoms. The leading causes of death are cardiac dysfunction and pulmonary edema. We present herein a case of scorpion sting in a 9-year-old boy who developed pulmonary edema and gradually developed cytotoxic cerebral edema with infarct leading to motor aphasia with upper motor neuron facial palsy.

Scorpion envenomation is a life-threatening toxicological emergency and considered as a major public health problem, especially in endemic regions (India, Africa, Latin America); it is generally characterized by low resources and tropical or subtropical weather. Scorpion envenomation is especially fatal in the first hours, usually due to respiratory and/or cardiovascular collapse. The neurologic manifestations, triggered by multiple neurotoxic mechanisms, are varied and complex and mostly reported in children. The aim of this review is to clarify the epidemiologic characteristics and clinical manifestations as well as diagnosis and management of neurologic complications following scorpion envenomation. The management of patients with severe clinical forms is based on early recognition of the sting, antivenom serum administration, and cardiorespiratory and systemic support.
