Eosinophilic colitis (EC) is a rare inflammatory disease that is part of the group of gastrointestinal eosinophilic diseases. Its etiology seems to involve allergic mechanisms comprising several interleukins and immune system cells (mainly eosinophils). It presents in distinct ways according to age, but at any stage of life it encompasses gastrointestinal symptoms. In addition, it is a condition with a predominance in males, according to some studies.

Amyand’s hernia is a rare condition consisting of the presence of the vermiform appendix within the hernia sac in the inguinal region. Despite not being frequent, or rarely reported, it deserves attention for proper care. Its involvement is more frequent in men of any age group and often goes unrecorded because the content of the hernial sac is reduced even before its identification.

Obesity can be associated with several diseases, signs, and symptoms. Among them, there is nutrient deficiency, especially vitamin D, which regulates calcium and phosphate and helps in bone remodeling. Vitamin D deficiency is related directly to the inadequate intake of foods rich in vitamins, less exposure to the sun and, mainly, to the sequestration of fat-soluble vitamins by the adipose tissue, making it even more difficult for the body to absorb them. Among these complications is the worsening of vitamin deficiency, with a focus on vitamin D, which is already present before the patient undergoes bariatric surgery. Regarding the types of bariatric surgery, each one establishes a degree of vitamin D deficiency that the patient will have postoperatively. That is, each type of bariatric surgery, as they are performed in different ways, directly interfere with the patient's absorption of vitamins. Postoperatively, vitamin D supplementation is recommended for all patients. However, due to poor patient compliance and lack of consent among physicians on the best form of supplementation, the deficiency is maintained, further impairing the treatment, and causing a worsening of the bariatric patient's condition.

Introdução: Na última década, foram registradas duas pandemias de grande impacto em saúde pública, a causada pelo vírus Influenza A, em 2009, e pelo SARS-CoV-2, iniciada ao final de 2019. Contudo, suas implicações transpõem os limites sanitários, abarcando questões importantes concernentes aos princípios bioéticos implícitos nestes contextos. O objetivo do estudo foi refletir sobre as medidas adotadas na prevenção e contenção de pandemias, analisando-as sob a ótica da bioética principialista. Materiais e métodos: Estudo descritivo, documental, de natureza qualitativa. Resultados: Observou-se que os países adotaram medidas preventivas no modelo de educação em saúde, limitação de atividades com o distanciamento social e a vigilância dos casos diagnosticados. Considerações finais: Com o estudo, foi possível observar o engajamento de todos os países no enfrentamento das pandemias, respeitando os princípios da bioética, a exceção da justiça e da autonomia, estas restringidas por ações técnicas e governamentais, e por escassez de recursos. Palavras-Chave: Bioética; Controle; Pandemia; Prevenção; Principialismo.
