ABSTRACT Dengue Fever, Zika and Chikungunya are febrile infectious diseases transmitted by the Aedes species of mosquito with a high rate of mortality. The most common vector is Aedes aegypti. According to World Health Organization outbreaks of mosquito-borne illnesses are common in the tropical and subtropical climates, as there are currently no vaccines to protect against Dengue Fever, Chikungunya or Zika diseases. Hence, mosquito control is the only known method to protect human populations. Consequently, the affected countries need urgently search for better tools and sustained control interventions in order to stop the growing spread of the vector. This study presents an optimization model, involving chemical, biological and physical control decisions that can be applied to fight against the Aedes mosquito. To determine solutions for the optimization problem a genetic heuristic is proposed. Through the computational experiments, the algorithm shows considerable efficiency in achieving solutions that can support decision makers in controlling the mosquito population.

A hipertermia maligna caracteriza-se por hipertermia, rigidez muscular, rabdomiólise, acidose e insuficiência de múltiplos órgãos. A hipertermia maligna anestésica decorre da exposição a halogenados e/ou relaxantes musculares despolarizantes. O método padrão para diagnosticar a suscetibilidade à hipertermia maligna é o teste da contratura muscular in vitro em resposta ao halotano e à cafeína. A síndrome maligna por neurolépticos caracteriza-se por hipertermia, síndrome extrapiramidal, acidose, instabilidade neurovegetativa e alterações neurológicas. Descrevemos três pacientes com síndrome maligna por neurolépticos e testes de contratura muscular positivos. Esse achado demonstra que ocasionalmente o músculo de pacientes com síndrome maligna por neurolépticos pode mostrar as alterações encontradas na hipertermia maligna anestésica.

Hyperthermia, skeletal muscle rigidity, rhabdomyolysis, acidosis and multiple system insufficiency characterize malignant hyperthermia. Anaesthetic malignant hyperthermia follows halogenated volatile agents and/or depolarizing muscle relaxants utilization. Diagnosis is based on in vitro muscle contracture in response to halothane and/or caffeine exposure. Neuroleptic malignant syndrome affects patients taking neuroleptic drugs; clinical findings include hyperthermia, extrapyramidal rigidity, acidosis, neurovegetative instability and neurological signs. We report three neuroleptic malignant syndrome patients with positive muscle contracture tests which shows that muscle from neuroleptic malignant syndrome patients may in some instances show alterations similar to those of anaesthetic malignant hyperthermia.
