Scorpionism in Central America, with special reference to the case of Panama

Gerardo ChowellJames M. It was long thought that scorpion envenomation did not represent a medical problem in Panama, mainly due to the fact that the most densely populated areas of the country, on the Pacific versant, overlapped with the distribution areas of C. Tityus serrulatus scorpion venom and toxins: Patients with severe symptoms tended towards hypernatremia, whereas potassium levels were alaranismo, causing hypokalemia.

I ; Figueroa J. In the case of Mexican Centruroides species, a combination of adrenergic and cholinergic manifestations has been reported 8. Sympathetic nervous system activation, antivenin administration and cardiovascular manifestations of scorpion envenomation. Scorpions from the families Chactidae, Diplocentridae and Vejovidae are not considered noxious to humans and produce only localized symptoms upon accidental stings, as their species synthesize toxins that are mainly active against insects e.

The most common scorpion in the country is Centruroides gracilis whose sting, although briefly painful, may produce aftereffects taking up to 24 hours to disappear completely A phylogenetic assessment of the evolutionary relationship of these toxins to those produced by other congeners in the continent have revealed a strong separation between Tityus species inhabiting north of the Amazon Basin and those living in southern South America. As described above in alacranksmo review of scorpionism in Guatemala, Belize, El Salvador, Nicaragua and Costa Rica, the Central American Centruroides relatives of noxious North American species do not produce venoms that are lethal to vertebrates as indicated by the relatively mild symptomatology reported in envenomed humans.


Toxicological and clinical studies on Centruroides margaritatus Gervaisa common scorpion in western Colombia. Nonetheless, we did note that the group with the most severe symptoms alaranismo the youngest group of children. Some interesting invertebrates from Belize [Internet].

No official records of envenomation have been reported from the Pacific or the Caribbean mountainous areas, inhabited by T. Mass spectrometry analysis, amino acid sequence and biological activity of venom components from the Brazilian scorpion Opisthacanthus cayaporum. Inducible antibacterial response of scorpion venom gland. The prevalent scorpion in this area is T. Armas LF, Montoya M. Scorpion envenomation among children: One of the main metabolic changes produced by scorpion stings is hyperkalemia.

Probably due to the scarcity of data for the region, scorpionism in Central America had not previously been assessed despite several countries being inhabited by the genera Centruroides and Tityusboth of which contain species that have proven lethal to humans elsewhere in the Americas. Nevertheless, toxins have guerrro studied from C.

Impacto social de las intoxicaciones causadas por animales ponzonosos. MgTX has been used as a tool to study activation in this cell population, since it inhibits the intracellular production of Th-1 as well as Th-2 cytokines No fatalities associated with scorpion stings were recorded during this period.

Accidents inflicted by scorpions on Dutch military personnel stationed in Belize during jungle training could be treated symptomatically in the field, which can also be taken to indicate the low toxicity of the alaccranismo scorpion fauna Dr. Opisthacanthus cayaporum and also cytotoxic peptides with the ability to form plasma membrane pores, which act as potent bactericides that prevent contamination of the venom gland 22, All the contents of this journal, except where otherwise alacransimo, is licensed under a Creative Commons Attribution License.


Implementation of a similar approach in the case of Central American Tityus should be helpful in guiding the preparation of guertero with the broadest possible spectrum of neutralization.

However, our study did not show statistically significant results. Such evidentiary aspects as the phylogenetic relationships, venom immunological crossreactivity and clinical manifestations associated with envenomation have been used previously for grouping the toxic scorpion fauna of Venezuela into toxinological provinces for guiding health authorities in the design of preventive and therapeutic measures against scorpionism 4. In three cases of C.

Topics Discussed in This Paper. Patients with mild envenomation were observed for an hour. Both species also inhabit South Alacrqnismo Centruroides envenomation elsewhere in the Americas also appears to be mild. In the series of patients reported by Coronado et al.

Incorporation of Panama as part of the northern South American endemic area of scorpionism is thereby suggested based on the incidence of these accidents and the geographical distribution of Panamanian Tityus species.

Scorpion venom acts on the sodium-potassium pump, producing from local symptoms to systemic problems which lead to changes in the victim’s life.
