Two scorpion species of medical importance occur in the state of São Paulo: the native brown scorpion Tityus bahiensis (Perty) and the highly toxic yellow scorpion Tityus serrulatus Lutz and Mello, which was brought into the state. The study of accident data of patients admitted to the Vital Brazil Hospital of the Butantan Institute from l982 to l993 revealed a gradual increase in stings by T. serrulatus in contrast to those by T. bahiensis with a variation from 5.2% to 29.7%. Also, an inventory of the scorpions sent to the Laboratory of Venomous Arthropods of the Butantan Institute over the same period showed an expressive growth in the number of T. serrulatus specimens in contrast to that of T. bahiensis. These data suggest a significative proliferation of T. serrulatus in the state of São Paulo over the past 12 years, and a probable interspecific competition between T. serrulatus and the endemic T. bahiensis. The analysis of scorpion accidents reported to the state of São Paulo Health Department (Secretaria de Estado da Saúde de São Paulo) corroborated the higher severity of T. serrulatus envenoming. The results pointed to the possibility of an increase in severe envenoming and deaths by scorpion stings in the state of São Paulo. Aiming to contribute to scorpion prevention and control programs, the present geographical distribution of both dangerous species was mapped, pointing to the areas of higher risk of scorpionism in the state

Hearing is one of the main forms of connection between human being and the environment; however, hearing loss is still diagnosed very late in Brazil, which directly interferes with the child's development. Aim The aim of this study was to check the knowledge pediatricians and gynecologists have about the risk factors for the deafness, the way they acquired such knowledge and parent education about the subject. Materials and Methods We enrolled 119 doctors from three public hospitals of the city of Recife. An interview was applied, before and after the educational campaign on the matter. The study was descriptive, cross-sectional, case series-type. Data analysis was descriptive and inferential. Results The results showed that only 3 of the 18 hearing loss risk factors listed had gotten answers above 50% in the initial stage of the study and 53.84% of the professionals educated the families. All the answers had increased in the second stage. Conclusion The results emphasize the need to pay more attention to this matter; therefore, primary care is an inexpensive and efficient way to fight hearing loss.
