ABSTRACT During the SARS-CoV-2 pandemic, we observed an increase in morbidity and mortality secondary to surgical procedures. The mortality rate for elective surgery is estimated at 19.1% and is 26% for emergency procedures. Additionally, approximately half of patients who undergo surgery while infected with SARS-CoV-2 experience postoperative pulmonary complications. Due to limitations caused by the health emergency, cancer treatments in our country have been affected in terms of hospitalization capabilities and implementation of chemotherapy treatments. We report the first ALPPS (associating liver partition with portal vein ligation for staged hepatectomy) procedure performed in northeastern Argentina on a patient with multiple colorectal metastases during the SARS-CoV-2 pandemic, with successful outcomes.

RESUMEN Durante la pandemia por SARS-CoV-2 evidenciamos un aumento de la morbimortalidad secundario a procedimientos quirúrgicos. Se estima una mortalidad a los 30 días del 19,1% en cirugías programadas y del 26% en procedimientos quirúrgicos de emergencia, y alrededor de la mitad de los pacientes que se someten a cirugía estando infectados con SARS-CoV-2 experimentan complicaciones pulmonares posoperatorias. Los tratamientos oncológicos sufrieron deficiencias en nuestro país debido a las limitantes secundarias a la emergencia sanitaria, en cuanto a capacidad de internación e implementación de los tratamientos quimioterápicos. Informamos la primera cirugía de ALPPS (associating liver partition with portal vein ligation for staged hepatectomy) realizada en el nordeste argentino en una paciente con metástasis colorrectales múltiples en contexto de la pandemia por SARS-CoV-2, con buenos resultados.

Eugenia caryophyllata, popularmente conhecida como "cravo-da-índia", cresce naturalmente na Indonésia e é cultivada em várias partes do mundo, incluindo o Brasil. O cravo-da-índia é utilizado em culinária, em farmácia, perfumaria e cosméticos. O óleo essencial extraído do cravo-da-índia cujo principal componente é o eugenol tem sido utilizado em odontologia como anti-séptico e analgésico. O objetivo deste estudo foi avaliar as atividades antiinflamatória e antinociceptiva do eugenol de uso odontológico, administrado oralmente, em modelos experimentais in vivo. A atividade antiinflamatória do eugenol foi avaliada através do volume de exsudato e migração leucocitária no teste de pleurisia e do edema de pata de rato induzido pela carragenina. A atividade antinociceptiva foi avaliada através dos testes de contorções induzidas pelo ácido acético e da placa quente. O eugenol (200 e 400 mg/kg) reduziu o volume de exsudato pleural sem interferir na contagem de leucócitos totais presentes na pleura. Na dose de 200 mg/kg, o eugenol inibiu significativamente o edema de pata, 2-4 h após a injeção do agente flogístico. No teste da placa quente, a administração do eugenol (100 mg/kg) mostrou atividade significativa à reação de desconforto-tempo dependente, avaliada como a latência da resposta, inibida pela meperidina. Eugenol na doses de 50, 75 e 100 mg/kg apresentou efeito antinociceptivo significativo no teste de contorções abdominais induzidas pelo ácido acético em comparação com o grupo controle. Os dados obtidos indicam que o eugenol apresenta atividade antiinflamatória e antinociceptiva periférica.

Eugenia caryophyllata, popular name "clove", is grown naturally in Indonesia and cultivated in many parts of the world, including Brazil. Clove is used in cooking, food processing, pharmacy; perfumery, cosmetics and the clove oil (eugenol) have been used in folk medicine for manifold conditions include use in dental care, as an antiseptic and analgesic. The objective of this study was evaluated the anti-inflammatory and antinociceptive activity of eugenol used for dentistry purposes following oral administration in animal models in vivo. The anti-inflammatory activity of eugenol was evaluated by inflammatory exudates volume and leukocytes migration in carrageenan-induced pleurisy and carrageenan-induced paw edema tests in rats. The antinociceptive activity was evaluated using the acetic acid-induced writhing and hot-plate tests in mice. Eugenol (200 and 400 mg/kg) reduced the volume of pleural exudates without changing the total blood leukocyte counts. At dose of 200 mg/kg, eugenol significantly inhibited carrageenan-induced edema, 2-4 h after injection of the flogistic agent. In the hot-plate test, eugenol administration (100 mg/kg) showed unremarkable activity against the time-to-discomfort reaction, recorded as response latency, which is blocked by meperidine. Eugenol at doses of 50, 75 and 100 mg/kg had a significant antinociceptive effect in the test of acetic-acid-induced abdominal writhing, compared to the control animals. The data suggest that eugenol possesses anti-inflammatory and peripheral antinociceptive activities.
