- Protocolo de Prevenção e Tratamento de Infeções Associadas à Terapêutica Imunossupressora de Doenças AutoimunesPublication . Valdoleiros, Sofia R.; Furtado, Isabel; Silva, Carolina; Correia Gonçalves, Inês; Santos Silva, André; Vasconcelos, Olga; Horta, Ana; Vasconcelos, A. Ludgero; Xará, Sandra; Gonçalves, Maria João; Abreu, Miguel; Sarmento-Castro, RuiWe propose a guideline about the risk, prevention and treatment of infection in the patient under immunomodulatory or immunosuppressive therapy in the context of autoimmune or autoinflammatory disease. It is divided into three sections: drugs and associated risk of infection; immunizations; risk, prevention, and treatment of specific infections. The treatment of autoimmune diseases involves the use of immunosuppressive or immunomodulatory therapies, with an increasing number of new drugs being used. It is associated with an increased risk of infection, which may be present globally or only for specific agents, varying widely depending on the pharmacological class and even within the same class. The prevention strategy and clinical management need to be individually tailored and there are several key factors: characterization of the disease that prompts the immunosuppression, understanding of the mechanism of action of the immunosuppressive drug, knowledge of previous infections, recognition of risk factors, laboratory test results, vaccine administration, monitoring of clinical signs and symptoms and patient education.
- Diagnosis of Asymptomatic Biliary Ascariasis by Abdominal Ultrasound in a Non-Endemic AreaPublication . Silva, Carolina; Gonçalves, Inês; Neves, Sara; Ferreira, Diana C; Valdoleiros, Sofia RBiliary ascariasis is rare in non-endemic areas. This infection is associated with severe complications of the biliary tract, which can become a medical emergency. Treatment with oral anthelmintics is often effective, but, in some cases, surgery is required. We describe an unusual case of ultrasound diagnosis of biliary ascariasis in the gallbladder in a patient who, besides residing in a low-prevalence area of the infection, did not present with biliary tract manifestations. We intend to raise awareness of this clinical entity in non-endemic areas, where this diagnosis is not usually considered. A brief review of the subject is also presented.
- Animais Venenosos em Território Português: Abordagem Clínica de Picadas e MordedurasPublication . Valdoleiros, Sofia R.; Gonçalves, Inês Correia; Silva, Carolina; Guerra, Diogo; Silva, Lino André; Martínez-Freiría, Fernando; Rato, Fátima; Xará, SandraThere are many native species of animals with the potential to cause severe disease in Portugal. Of the four clinically relevant snake species, the vipers (Vipera latastei and Vipera seoanei) are the most concerning. They can cause severe disease and require in-hospital management, monitoring and specific treatment, including the administration of anti-snake venom serum. The Malpolon monspessulanus and Macroprotodon brevis snakes cause mostly localized clinical manifestations, which do not require specific treatment. Only a minority of the spider species in Portugal possess chelicerae (mouthparts of the Chelicerata, shaped as either articulated fangs or pincers, which may contain venom or be connected to the venom glands and are used for predation or capture of food) long enough to perforate the human skin. Nevertheless, Latrodectus tredecimguttatus and Loxosceles rufescens spider bites may require specialized treatment in a hospital setting, as well as careful active symptom surveillance. Diversely, the treatment for Scolopendra cingulata and Scolopendra oraniensis centipedes' bites is merely symptomatic. The only existing scorpion species in Portugal is the Buthus ibericus; its sting typically causes local symptoms with intense pain, and its treatment consists essentially of analgesia. The insects of the Hymenoptera order, such as bees and wasps, have the ability to inject venom into the skin. Most people present only with local or regional inflammatory response, and symptomatic treatment is usually effective. Even so, individuals with hypersensitivity to bee venom may develop anaphylaxis. Several marine species in the Portuguese coast are venomous to humans, including weeverfish (Trachinidae family), stingrays (Dasyatis pastinaca, Taeniura grabata, Myliobatis aquila), red scorpion fish (Scorpaena scrofa), cnidaria (Pelagia noctiluca, Chrysaora hysoscella, Physalia physalis) and bearded fireworm (Hermodice carunculata); treatment is symptomatic. Contact with the larvae or bristles (chitinous structures with locomotor or tactile functions) of Thaumetopoea pityocampa (pine processionary) can cause cutaneous, ocular and, rarely, respiratory reactions; its management is also symptomatic.
