In 1909 Carlos Chagas discovered a new parasite, the Trypanosoma cruzi (T cruzi) and described, in greater detail, its cycle of transmission (vector, hosts) and the acute clinical manifestations of the first human case of the disease that bears his name.1 A few years later, the main clinical form of this new morbid entity—Chagas heart disease—was fully characterized.2 Paleoparasitology studies ...

Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor...

scorpion stinging is one of the major causes of mortality in the tropical and subtropical countries. hemiscorpius lepturus, androctonus crassicauda and mesobuthus eupeus are most important species that cause a lot of scorpion stings in iran. in the present research, effects of h. lepturus envenomation on blood and urine in stung persons who referred to the health center of hendijan sw iran were...

She was admitted to hospital on the second day with localized pain, oedema, abdominal pain and anuria. Chest pain and neurological symptoms were absent. She was febrile and blood pressure was 180/100mmHg. The total white cell count was 23x103μl with neutrophil leukocytosis, platelet count 88x103/μl, C reactive protein 232mg/dl (normal <0.6mg/dl) and serum creatinine 468 μmol/l, and blood pictur...

Background: Hemiscorpius lepturus envenomation is one of the most important medical issues in tropical regions of Iran, especially Khuzestan Province. Due to lack of reliable data about scorpion sting in Khuzestan Province, this investigation was performed to study the clinical presentation, prognosis factors, complications and mortality rates of Hemiscorpius lepturus sting. Methods: this study...

A 50 yr old female developed transient ST segment elevation due to an acute coronary vasospasm following a Indian Red Scorpion sting and the angiogram revealed 50% occlusion in right coronary artery (RCA).The possible mechanism is that the sympathetic over-activity could have aggravated the occlusion in the RCA as the RCA is more commonly prone to spasm compared to the other coronary arteries.

We describe the case of a 32-year-old male patient that sought medical treatment complaining of severe pain in his second and third right-hand fingers. The symptoms had started two hours before. The hypotheses of spider bite, scorpion or insect sting and injury caused by a foreign body were considered in the differential diagnoses. On dermoscopy, two foreign bodies were identified on his skin. ...

SUMMARY Two web-based applications to analyze amino acids three-dimensional (3D) local environment within protein structures-SCORPION and FORMIGA-are presented. SCORPION and FORMIGA produce a graphical presentation for simple statistical data showing the frequency of residue occurrence within a given sphere (defined here as the 3D contacts). The center of that sphere is placed at the Calpha and...
