Throughout his life, he dedicated himself to documenting and preserving arachnological knowledge, contributing valuable work on scorpion taxonomy, distribution, and bibliography. His careful attention to the literature helped bring clarity and organization to a field whose history spans centuries and many languages. Gérard was also closely associated with the journal Arachnides , which became an important outlet for sharing research, faunistic records, and historical notes within the arachnological community. Through this work, he helped ensure that observations and studies—large and small—were preserved and made accessible to others with similar scientific interests. Beyond his scholarly contributions, Gérard was a humble and gen...

Ischemic stroke in a 4 year child resulting from scorpion envenomation: A case report from Nepal.

Introduction
The scorpion sting is one of the most go to forms of envenomation in countries with tropical climates. There are a variety of scorpions, and some of them have venom that could be detrimental to human beings. Non-fatal symptoms are common, which include pain, burning sensation, and change in color of the skin. Scorpion venom contains neurotoxins, which trigger the body to release endogenous catecholamines and acetylcholine. Systemic envenomation invites autonomic instability with a wide range of manifestations, including cardiovascular (hypertension, tachycardia, arrhythmias, myocarditis, distributive and cardiogenic shock), pulmonary (acute respiratory distress syndrome, pulmonary edema, atelectasis, bronchospasm), acute renal dysfunction, neurological emergencies (seizures, ischemia, hemorrhage, and rarely demyelination), and disseminated intravascular coagulation. A sympathetic storm may or may not follow the initial parasympathetic overdominance phase, which displays emesis, abdominal pain, excessive salivation, bradycardia, and pupillary constriction. Cerebrovascular injury in systemic envenomations is considered very odd. Globally, it has been documented in only 2% to 5% of cases of scorpionism. 1,2,3,4,5,6,7,8
We hereby present the case of a 4 year old child with features consistent with autonomic storm following scorpion sting who later developed left sided ischemic stroke. However,he lacked features of defibrination syndrome and myocarditis. Therefore, the most speculated cause of stroke in our patient was presumed to be the autonomic storm and toxin associated vasculitis.
