Exploratory Study on Occupational Health Exposure to Chemical Agents, in a Public Hospital in Valencia, Venezuela. Preliminar Assessment

Descriptive study that identified chemical agents (AQ) use and training on risk management and waste disposal techniques in a public Hospital in Valencia. A questionnaire was answered by 48 workers. Information obtained was: personal data, occupational history, AQ used; knowledge of risk management and waste disposal. There were 16 occupations from 12 “High Risk” areas. “Adult emergency” was the one with more workers (11 individuals), followed by “sterilization” and “clinical laboratory” (7 each) and oncology (5). The remained areas had less than 8.3% workers. The most used anesthetic agents were: Halothane, Enfluorane and Isofluorane 4.17% each and main antineoplastics used were: Doxorubicin 16.67% and Paclitaxel, 5-Fluoracil and Etoposide, 8.33% each. The most mentioned substances were: alcohol (70.8%) and Chlorine (64.6%). None of the answers regarding knowledge of AQ’ risk management and waste disposal was satisfactory. Statistical associations between training and several variables such as age, time in their job and being or not a professional, resulted non-significant. The correlation between training and the knowledge of AQ’s management was significant (p < 0.001). Participants showed that their knowledge about chemical occupational risk factors they are exposed to is still insufficient. Therefore, this theme should be included in graduate course curricula. These results provide important data and will serve as a pilot research for the follow up Phase II study that will include clinical aspects and environmental and biological monitoring.

Consumo de sustancias y noxas prenatales en madres de pacientes con síndrome de Möbius y Möbius Like

Introducción: El síndrome de Möbius y Möbius Like es una entidad poco frecuente caracterizada principalmente por parálisis congénita del VI y VII par craneal. Su etiología es poco conocida aunque se ha asociado a inductores del aborto. El objetivo de este estudio es describir factores anómalos, tóxicos o nocivos que hayan estado presentes en el embarazo de las madres de estos pacientes. Metodología: se realizó una encuesta auto-diligenciable a 15 madres de pacientes con el diagnóstico, indagando sobre condiciones anómalas y/o exposicionales del embarazo, el padre y el ambiente. Resultados: Las madres se encontraban entre los 16 y 34 años al momento de quedar embarazadas, en su mayoría eran solteras, estudiantes y sin planes de embarazo. Once en total usaron algún medicamento y/o sustancias durante la gestación; seis de ellas Misoprostol (40%). Las otras sustancias utilizadas incluyeron: alternativas, cigarrillo, alcohol, ibuprofeno, anticonceptivos, otros. Como anomalías del periodo prenatal se reportaron sangrado activo y/o amenaza de aborto, infección, exposición a químicos ambientales y enfermedad materna activa. Las condiciones paternas descritas fueron alcoholismo y/o drogadicción, enfermedad y edad ≥ 40 años en bajo porcentaje. Conclusión: El síndrome de Möbius y Möbius Like es una patología poco frecuente de la cual aún se debe seguir investigando sobre su etiología, para plantear posibles medidas de prevención.
