ABSTRACT Intestinal worm infections, referred to as helminthiases, represent a significant global health challenge, particularly in low- and middle-income countries. These infections affect millions of people and contribute to malnutrition, anemia, and impaired cognitive development, particularly in children. Nitazoxanide, first described in 1975, was initially developed as a veterinary anthelmintic. It has shown efficacy against various pathogens including Giardia lamblia, Entamoeba histolytica, and Cryptosporidium parvum. Recently, its use has expanded due to its observed in vitro activity against viruses, including […]

ABSTRACT Food allergies are the leading cause of anaphylaxis in children. Cofactors, such as exercise and non-steroidal anti-inflammatory drugs, may influence the occurrence and severity of allergic reactions to food. However, despite their relevance, the underlying mechanisms of cofactor-enhanced food allergies remain poorly understood. We report the case of a 12-year-old girl with mitochondrial DNA depletion syndrome who was referred to an allergy appointment due to suspected ibuprofen hypersensitivity. Detailed anamnesis, laboratory assessment, and negative drug challenge results excluded this […]

ABSTRACT Circulatory shock is a common fatal condition. Despite this, information on this syndrome in the current medical literature is fragmented and esoteric. Adherence to each basic element of care can have a profound impact on patient outcomes. Disturbances in pumping (cardiogenic), content/container relationship (hypovolemic and vasoplegic), or blockage in blood circulation (obstructive) can induce tissue hypoperfusion, causing hemodynamic shock. If not quickly reversed, hypoperfusion progresses to irreversible multi-organ failure. The course can be fatal even before reaching this stage […]

RESUMO Paciente do sexo masculino, 33 anos, com asma e rinite alérgica desencadeadas por ácaros, relatou episódio de angioedema facial e labial, dispneia, tosse e disfagia aos 25 anos, minutos após a ingestão de uma pizza de cogumelo ( Agaricus bisporus ). O paciente negou consumo de medicamentos, picadas de himenópteros, ou quaisquer outros possíveis desencadeadores ou cofatores que pudessem estar presentes. Desde então, evita todos os tipos de cogumelos, até a ocorrência de um contato acidental com molho de […]

A fluoresceína endovenosa é associada a pequenos efeitos adversos durante a angiografia da retina, a maioria deles sem gravidade e não relacionada a mecanismos imunológicos. Entretanto, em raras ocasiões, pode ocorrer reação anafilactoide; fatalidades envolvendo o uso de fluoresceína têm sido descritas. Complicações graves após injeção endovenosa de fluoresceína requerem ação imediata da equipe envolvida, assim como treinamento regular para padronizar o tratamento.
