ABSTRACT:The epidemiology and clinical findings of scorpion stings in Sanliurfa region of Turkey, from May to September 2003, were evaluated in this study.Mesobuthus eupeus (M. eupeus) plays a role on 25.8% of the scorpionism cases.This study also showed that intoxications caused by M. eupeus in the southeast of Anatolia region were seen in hot months of the summer, especially on July. Females and people above 15 years old were mostly affected and stung on extremities.Intense pain in the affected area was observed in 98.7% cases, hyperemia in 88.8%, swelling in 54.6%, burning in 19.7%, while numbness and itching were seen less frequently. In our study, the six most frequently observed symptoms were local pain, hyperemia, swelling, burning, dry mouth, thirst, sweating, and hypotension. In this study involving 152 M. eupeus toxicity cases, patients showed local and systemic clinical effects but no death was seen. Autonomic system and local effects characterized by severe pain, hyperemia and edema were dominantly seen in toxicity cases.
Precise knowledge of the natural history of cystic echinococcosis (CE) in humans remains somewhat arcane. The aim of the present study was to determine whether aspects of the natural history of established human infection with Echinococcus granulosus could be investigated by using a cross-sectional approach, in a community where CE was endemic. A mass ultrasound-screening survey, coupled with a questionnaire to record all previous surgical histories related to CE, was carried out amongst the primarily transhumant Berber people of the Mid Atlas mountains in Morocco. During two periods of intensive screening, of 10 days in May 2000 and 11 days in May 2001, 11,612 people, representing > 98% of the local population, were checked. One hundred and twenty six (1.1%) of the subjects--75 (59.5%) of the 6864 females investigated and 51 (40.5%) of the 4748 males--were found ultrasound-positive for CE. Overall, 14.1% of the CE cases detected were children aged 1-15 years (who made up 44% of the study population). Most (77.4%) of the ultrasound-positive subjects investigated were also found seropositive for CE. The frequency of a past history of surgery for CE increased with subject age (P = 0.024), 125 (1.1%) of the subjects being recorded as having had such surgery. The frequency of surgery for pulmonary CE was relatively constant in all age-groups, indicating that infection can occur at any time. The frequency of abdominal CE increased with age (R2 = 0.8102). Assuming that the incidence of infection remains fairly constant over time and that the longer a person spends in this endemic area the more likely it is that he or she will develop CE, then a progression from active through transitional to inactive CE should occur. The cysts observed by ultrasound in the present study were categorized, as type 1, 2, 3, 4 or 5, according to the new, standardized, ultrasound classification of CE developed by the World Health Organization (WHO). There was a clear exponential decline in the frequency of the various cyst types, from type 1 (the most frequent) to type 5 (the rarest). This decline validates the assumptions made, about the natural history of established CE, by those who developed the WHO's classification. The classification should therefore be invaluable to surgeons and clinicians, when they have to consider treatment options for patients with the various types of CE, and to policy makers trying to establish the economic costs of treating CE in endemic settings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
