Scorpion stings in Turkey: epidemiological and clinical aspects between the years 1995 and 2004
Pediatric epidemiological aspects of scorpionism and report on fatal cases from Tityus stigmurus stings (Scorpiones: Buthidae) in State of Pernambuco, Brazil
Serum electrolyte changes in pediatric patients stung by scorpions
Scorpion sting is a health problem in some places of Mexico. The clinical manifestations of scorpion envenomation are variable and include metabolic alterations. Hyperkalemia is the most frequently reported metabolic alteration. We conducted a prospective, observational, descriptive and transversal study in an emergency room at Hospital del Niño Morelense, Mexico. Eighty-two patients were included and classified as mild (17%) moderate (33%) and severe (46%). The mean serum level of sodium was 146.4meq/l, standard deviation (SD) 5.58; potassium 3.86meq/l, SD 0.53, and calcium 9.55mg/dl, SD 0.76. We found 30.4% hypernatremia, 12% hypokalemia, 10.9% abdominal distension, and 14.6% visual alterations
Accident caused by Centruroides testaceus (DeGeer, 1778) (Scorpiones, Buthidae), native to the Caribbean, in Brazilian airport
Describes the case of a 6-year-old girl who was stung by a Centruroides testaceus, a scorpion native to the Lesser Antilles, in the Guarulhos International Airport, São Paulo, Brazil, as she disembarked from a flight coming from the Caribbean. The patient presented only local symptoms (a small area of erythema and pain at the sting site), which were resolved after a few hours with analgesics, without the need for antivenom. Physicians who treat patients stung by scorpions should be alert to the possibility of such accidents being caused by non native species, especially those cases that occur near airports or ports
Air pollution is associated with brainstem auditory nuclei pathology and delayed brainstem auditory evoked potentials
We assessed brainstem inflammation in children exposed to air pollutants by comparing brainstem auditory evoked potentials (BAEPs) and blood inflammatory markers in children age 96.3±8.5 months from highly polluted (n=34) versus a low polluted city (n=17). The brainstems of nine children with accidental deaths were also examined. Children from the highly polluted environment had significant delays in wave III (t(50)=17.038; p7.501; p<0.0001), consisting with delayed central conduction time of brainstem neural transmission. Highly exposed children showed significant evidence of inflammatory markers and their auditory and vestibular nuclei accumulated α synuclein and/or β amyloid1-42. Medial superior olive neurons, critically involved in BAEPs, displayed significant pathology. Children's exposure to urban air pollution increases their risk for auditory and vestibular impairment
