Does acute alcohol intoxication interfere with colonic anastomosis wound healing? : a rat model of nondestructive colon trauma

PURPOSE: To evaluate the effects of acute alcohol intoxication on healing of colonic anastomosis. METHODS: Thirty-six rats were allocated into two groups. Animals in the alcohol (A) were given 2 mL of ethanol diluted in 0.9% saline solution to a concentration of 40% by gavage immediately before anesthesia, whereas control (C) animals received 2 mL of 0.9% saline solution via the same route. A colonic anastomosis was then performed in all animals. On postoperative days 1, 3, and 7, anastomotic breaking strength was assessed and histopathological examination was performed. Change in body weight and mortality were also evaluated. RESULTS: The median of anastomotic tensile strength on the postoperative day 1 was 0.09 Newtons for group A and 0.13 for group C. (p>0.05). The median of anastomotic tensile strength on the postoperative day 3 was 0.13 Newtons for group A and 0.17 for group C. (p>0.05). The median of anastomotic tensile strength on the postoperative day 7 was 0.30 Newtons for group A and 0.35 for group C. (p>0.05). There was no significant difference between the groups A and C, in the first, third or seventh POD (p>0.05), in any of the analyzed parameters. There were no statistical differences between groups in the weight. Three animals died, all from the group A. CONCLUSION: Acute alcohol intoxication did not interfere with wound healing of colonic anastomoses, although it caused early postoperative mortality

Gangrena de fournier com complicações em lactente do sexo feminino: Um relato de caso / Fournier's gangrene with complications in a female infant: A case report

A Gangrena de Fournier (GF) é uma fasceíte necrosante progressiva e grave da região genital, perineal ou perianal com possível extensão para abdome e região proximal da coxa. Acomete predominantemente adultos do sexo masculino entre 50 e 60 anos, sendo extremamente rara em crianças do sexo feminino. É uma condição patológica com risco de vida iminente devido à rápida evolução e severidade das complicações, portanto, requer tratamento imediato e agressivo com antibioticoterapia de amplo espectro, desbridamento cirúrgico e cuidados intensivos multidisciplinares. Esse relato apresenta um raro caso de GF em lactente do sexo feminino, sem fatores predisponentes identificáveis, que evoluiu com sepse e lesão renal aguda

In vitro effects of European and Latin-American medicinal plants in CYP3A4 gene expression, glutathione levels, and P-glycoprotein activity

Many medicinal plants species from European -such as Artemisia absinthium, Equisetum arvense, Lamium album, Malva sylvestris, Morus nigra, Passiflora incarnata, Frangula purshiana, and Salix alba- as well as Latin American traditions -such as Libidibia ferrea, Bidens pilosa, Casearia sylvestris, Costus spicatus, Monteverdia ilicifolia, Persea americana, Schinus terebinthifolia, Solidago chilensis, Syzygium cumini, Handroanthus impetiginosus, and Vernonanthura phosphorica- are shortlisted by the Brazilian National Health System for future clinical use. However, they lack many data on their action upon some key ADME targets. In this study, we assess non-toxic concentrations (up to100 μg/ml) of their infusions for in vitro ability to modulate CYP3A4 mRNA gene expression and intracellular glutathione levels in HepG2 cells, as well as P-glycoprotein (P-gp) activity in vincristine-resistant Caco-2 cells (Caco-2 VCR). We further investigated the activation of human pregnane X receptor (hPXR) in transiently co-transfected HeLa cells and the inhibition of Gamma-glutamyl transferase (GGT) in HepG2 cells. Our results demonstrate L. ferrea, C. sylvestris, M. ilicifolia, P. americana, S. terebinthifolia, S. cumini, V. phosphorica, E. arvense, P. incarnata, F. purshiana, and S. alba can significantly increase CYP3A4 mRNA gene expression in HepG2 cells. Only F. purshiana shown to do so likely via hPXR activation. P-gp activity was affected by L. ferrea, F. purshiana, S. terebinthifolia, and S. cumini. Total intracellular glutathione levels were significantly depleted by exposure to all extracts except S. alba and S. cumini This was accompanied by a lower GGT activity in the case of C. spicatus, P. americana, S. alba, and S. terebinthifolia, whilst L. ferrea, P. incarnata and F. purshiana increased it. Surprisingly, S. cumini aqueous extract drastically decreased GGT activity (−48%, p < 0.01). In conclusion, this preclinical study shows that the administration of some of these herbal medicines causes in vitro disturbances to key drug metabolism mechanisms. We recommend active pharmacovigilance for Libidibia ferrea (Mart.) L. P. Queiroz, Frangula purshiana Cooper, Schinus terebinthifolia Raddi, and Salix alba L. which were able to alter all targets in our preclinical study

A influência da síndrome de ovários policísticos e síndrome metabólica na escolha do tipo de parto: revisão de literatura

Introduction: Polycystic Ovary Syndrome (PCOS) and Metabolic Syndrome (MS) are interconnected through various physiological pathways, and their coexistence may have significant implications, especially during pregnancy and the childbirth process. During pregnancy, women with PCOS and MS may face an increased risk of obstetric complications. Regarding the impact on childbirth, PCOS and MS can influence the choice of the type of delivery. Methodology: This work constitutes a literature review, following the systematization with the five pillars described below. 1) Problem statement: "What is the influence of PCOS and MS on the choice of the type of delivery?". 2) Relevant studies were identified using the PUBMED platform with the descriptors "Metabolic Syndrome, Polycystic Ovary Syndrome, Parturition, Pregnancy," PUBMED all in accordance with MESH. 3) Initially, 11 studies were selected; 4 were discarded after a thorough reading as they did not contribute to the problem statement. 4) Data extraction was performed using a text editing program. 5) Experts were consulted. Results: The studies revealed that PCOS and MS are associated with a clinically significant increase in the risk of complications during pregnancy compared to control groups. Additionally, there is a 3 to 4 times higher likelihood of developing pregnancy-induced hypertension and preeclampsia, a threefold increase in the risk of gestational diabetes, and a twofold likelihood of premature birth. The elevated obstetric risk for women with PCOS is reflected in a higher rate of spontaneous abortion. Moreover, it was observed that, compared to the general population, PCOS and MS are more associated with cesarean delivery. Conclusion: Cesarean delivery is predominant in patients with PCOS and MS. Furthermore, there is a higher risk of developing pregnancy-induced hypertension, preeclampsia, and premature birth.Introdução: A síndrome dos ovários policísticos (SOP) e a síndrome metabólica (SM) estão interligadas por várias vias físicas, e sua coexistência pode ter implicações significativas, especialmente durante a gravidez e no processo de parto. Durante a gravidez, as mulheres SOP e SM podem enfrentar um risco aumentado de complicações obstétricas. Quanto ao impacto no parto, a SOP e a SM podem influenciar a escolha do tipo de parto Metodologia: Este trabalho trata-se de uma revisão de literatura, de acordo com a sistematização com os 5 pilares descritos a seguir. 1) Questão problema: “Qual a influência da SOP e SM na escolha do tipo de parto?”. 2) Estudos relevantes foram identificados utilizando na plataforma PUBMED os descritores “Metabolic Syndrome, Polycystic Ovary Syndrome, Parturition, Pregnancy”, na PUBMED, todos de acordo com MESH. 3) 11 estudos foram selecionados inicialmente, 4 foram descartados mediante leitura completa por não contribuir com a questão problema. 4) A extração de dados foi realizada em um programa de edição de texto. 5) Especialistas foram consultados.&nbsp; Resultado: Os estudos revelaram que a SOP e SM estão associadas a um aumento clinicamente significativo no risco de complicações durante a gravidez, em comparação com os grupos de controle. Além disso, há uma probabilidade de 3 a 4 vezes maior de desenvolver hipertensão causada pela gravidez e pré-eclâmpsia, um aumento de 3 vezes sem risco de diabetes gestacional e uma probabilidade duas vezes maior de parto prematuro. O risco obstétrico elevado para mulheres com SOP se reflete em uma maior taxa de aborto espontâneo. Diante disso, observou-se que em relação a população em geral, SOP e SM associam-se mais com o parto cesariano. Conclusão: O parto cesariano é predominante em pacientes com SOP e SM. Além disso, há maior risco de desenvolver hipertensão causada pela gravidez, pré-eclâmpsia e parto prematuro
