Industrial production of food for animals and humans needs increasing amounts of pesticides, especially of organophosphates, which are now easily available worldwide. More than 3 million cases of acute severe poisoning are estimated to occur worldwide every year, and even more cases remain unreported, while 200,000–350,000 incidentally or intentionally poisoned people die every year. Diagnostic and therapeutic procedures in organophosphate poisoning have, however, remained unchanged. In addition to several neurologic symptoms (miosis, fasciculations), hypersecretion of salivary, bronchial, and sweat glands, vomiting, diarrhea, and loss of urine rapidly induce dehydration, hypovolemia, loss of conscience and respiratory distress. Within hours, signs of acidosis due to systemic hypoxia can be observed at first laboratory investigation after hospitalization. While determination of serum-cholinesterase does not have any diagnostic value, it has been established that hypoalbuminemia alone or accompanied by an increase in creatinine, lactate, or C-reactive protein serum levels has negative prognostic value. Increased serum levels of C-reactive protein are a sign of systemic ischemia. Protective mechanical ventilation should be avoided, if possible. In fact, acute respiratory distress syndrome characterized by congestion and increased weight of the lung, accompanied by heart failure, may become the cause of death. As the excess of acetylcholine at the neuronal level can persist for weeks until enough newly, locally synthesized acetylcholinesterase becomes available (the value of oximes in reducing this time is still under debate), after atropine administration, intravenous albumin and fluid infusion should be the first therapeutic interventions to reestablish normal blood volume and normal tissue oxygenation, avoiding death by cardiac arrest.

INTRODUCTION: This study aimed to isolate and identify Candida spp. from the environment, health practitioners, and patients with the presumptive diagnosis of candidiasis in the Pediatric Unit at the Universitary Hospital of the Jundiaí Medical College, to verify the production of enzymes regarded as virulence factors, and to determine how susceptible the isolated samples from patients with candidiasis are to antifungal agents. METHODS: Between March and November of 2008 a total of 283 samples were taken randomly from the environment and from the hands of health staff, and samples of all the suspected cases of Candida spp. hospital-acquired infection were collected and selected by the Infection Control Committee. The material was processed and the yeast genus Candida was isolated and identified by physiological, microscopic, and macroscopic attributes. RESULTS: The incidence of Candida spp. in the environment and employees was 19.2%. The most frequent species were C. parapsilosis and C. tropicalis among the workers, C. guilliermondii and C. tropicalis in the air, C. lusitanae on the contact surfaces, and C. tropicalis and C. guilliermondii in the climate control equipment. The college hospital had 320 admissions, of which 13 (4%) presented Candida spp. infections; three of them died, two being victims of a C. tropicalis infection and the remaining one of C. albicans. All the Candida spp. in the isolates evidenced sensitivity to amphotericin B, nystatin, and fluconazole. CONCLUSIONS: The increase in the rate of hospital-acquired infections caused by Candida spp. indicates the need to take larger measures regarding recurrent control of the environment. INTRODUÇÃO: Isolar e identificar Candida spp. do ambiente, dos profissionais de saúde e de pacientes com diagnóstico presuntivo de candidíase, em Unidade de Pediatria do Hospital Universitário da Faculdade de Medicina de Jundiaí, verificar a produção de enzimas consideradas fatores de virulência e identificar a resistência das cepas isoladas dos pacientes aos antifúngicos. MÉTODOS: Foram feitas 283 coletas no período entre março e novembro de 2008 de forma randomizada do ambiente, das mãos de profissionais de saúde e de todos os pacientes com casos suspeitos de infecção hospitalar por Candida spp., triados pelo Comitê de Infecção Hospitalar. Todo o material coletado foi processado e as leveduras do gênero Candida foram isoladas e identificadas pelas características macroscópicas, microscópicas e fisiológicas. RESULTADOS: A incidência de Candida spp. no meio-ambiente e funcionários foi de 19,2%. Destes, as espécies mais frequentes entre os funcionários foram C. parapsilosis e C. tropicalis; no ar ambiente, C. guilliermondii e C. tropicalis; nas superfícies dos ambientes, C. lusitanae e nos sistemas de climatização, C. tropicalis e C. guilliermondii. No período de estudo, foram feitas 320 internações, e 13 (4%) apresentaram infecção hospitalar por Candida spp, sendo que 3 pacientes foram a óbito, dois apresentando infecção por C. tropicalis e um por C. albicans. Todas as espécies de Candida spp. isoladas dos pacientes foram sensíveis à anfotericina B, nistatina e fluconazol. CONCLUSÕES: Verificamos um aumento crescente de infecções hospitalares por Candida não albicans, o que sugere a necessidade de maiores precauções em relação a um controle ambiental destas espécies.
