RESUMEN
Bipolar disorder (BD) is associated with systemic toxicity, represented by changes in biomarkers associated with mood episodes, leading to neurological damage, which may reflect cognitive functions and functionality and the progression of the disease. We aimed to analyze the effect of four biomarkers, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and thiobarbituric acid reactive substances (TBA-RS), related to oxidative stress in BD and to correlate them with cognitive functions and functionality. We studied 50 bipolar types I/II patients in the euthymic phase, which was divided into two subgroups with 25 patients each (≤ 3 years and ≥ 10 years of diagnosis, from the first episode of mania) and 25 control patients. To analyze frontal cognitive functions and functionality, we used the Frontal Assessment Battery (FAB) and Functioning Assessment Short Test (FAST) tests, respectively. The scores of the FAST and FAB tests showed an increase and decrease respectively, in both bipolar groups, when compared to the control group, demonstrating impairment in cognitive functions and functionality since the disease onset. In addition, changes occurred in all six domains of the FAST test, and in four domains of the FAB test in bipolar patients when compared to the control group. Regarding oxidative stress biomarkers, we did not find changes in SOD and GSH-Px activities; however, a significant increase in CAT activity and lipid peroxidation was observed in both groups, although the patients were euthymic and medicated. These results allow us to raise the hypothesis that since the beginning of the disease, the euthymic bipolar patient has presented a level of oxidative stress, which gets worse with the evolution of the disease, promoting impairments in the frontal cognitive functions and functionality gradually.

Introdução: Os carcinomas de pele do tipo não melanoma são responsáveis por 30% dos tumores malignos no Brasil. O objetivo deste artigo foi avaliar o perfil epidemiológico e a conduta tomada a partir do diagnóstico histopatológico de margens comprometidas em pacientes com carcinomas de pele do tipo não melanoma tratados primariamente com cirurgia. Métodos: Estudo tipo coorte retrospectivo observacional. Os dados foram coletados de prontuário eletrônico de 1495 pacientes, apresentando 2457 carcinomas de pele do tipo não melanoma, operados entre janeiro de 2015 a dezembro de 2019. Resultados: Houve maior prevalência em homens (52,4%) e entre a sexta e a sétima décadas de vida (41,1%). O carcinoma basocelular foi o tipo histológico mais comum (75%). O risco de desenvolver carcinoma espinocelular foi 57,2% maior em pacientes com idade acima de 61 anos (risco relativo=1,572 (IC 95%: 1,316-1,878; p<0,0001)). Margens comprometidas foram reportadas em 15,8% dos casos, sendo mais comuns na face (19,5%) e nos pacientes com carcinoma espinocelular (p<0,05), com risco relativo=1,382 (IC95%:1,135-1,683; p=0,0013). Tratamento adicional foi indicado em 74,6% dos casos, sendo as condutas mais comuns a ampliação de margens (55,6%) e radioterapia (42,4%). A escolha entre intervenção ou observação apresentou relação com o tipo histológico (p<0,05), porém não foi possível afirmar sua relação com a faixa etária (p>0,05). Conclusão: O estudo possibilitou melhor compreensão do perfil dos pacientes com carcinomas de pele do tipo não melanoma, bem como o percentual de margens comprometidas após excisão cirúrgica inicial e o tratamento realizado.
Introduction: Non-melanoma skin neoplasms are responsible for 30% of all malignant tumors in Brazil. The main objective of this article was to evaluate the epidemiological profile and the approach taken from the histopathological diagnosis of compromised margins in patients with non-melanoma skin neoplasms treated primarily with surgery. Methods: This is an observational retrospective cohort. Data were collected from electronic medical records of 1495 patients, resulting in 2457 non-melanoma skin neoplasms, from January 2015 to December 2019. Results: There was a higher prevalence in men (52.4%) and between the sixth and seventh decades of life ( 41.4%). Basal cell carcinoma was the most common histological type (75%). Those over the age of 61 are 57.2% more likely to develop basal cell carcinoma (relative risk=1,572 (95% CI: 1,316-1,878; p<0. 0001). Compromised margins were reported in 15.8% of cases, being more common on the face (19.5%) and in patients with basal cell carcinoma (p<0.05), with relative risk=1,382 (95%CI: 1,135-1,683; p=0.0013). Additional treatment was indicated in 74.6% of cases, with the most common approaches being margin expansion (55.6%) and radiotherapy (42.4%). The choice between intervention or observation was related to the histological type (p<0.05), but it was not possible to affirm its relationship with the age group (p>0.05). Conclusion: The study allowed a better understanding of the profile of patients with non-melanoma skin neoplasms and the percentage of compromised margins after initial surgical excision and the treatment performed.
RESUMEN
INTRODUCTION AND IMPORTANCE: Duodenal trauma is rare, however, it has high morbidity and mortality rates. Surgical treatment modalities are employed depending on severity, ranging from simple sutures to complex pancreaticoduodenectomy cases. CASE PRESENTATION: A male patient had a circular saw accident, leading to evisceration in an extensive wound from the thoracoabdominal transition to the inguinal region, with 75% laceration of the second duodenal portion circumference, laceration in hepatic segments, section from right mesocolon to transverse colon, and multiple perforations in small bowel loops between 70 and 90 cm from the angle of Treitz. Laterolateral duodenum enteroanastomosis was performed with proximal jejunum and gastroenteroanastomosis with the distal loop of the small intestine at 90 cm from the Treitz angle, and a termino lateral enteroanastomosis between food and the biliary loop at 20 cm from the gastroenteroanastomosis. CLINICAL DISCUSSION: This report presents a new surgical technique for patients with penetrating duodenal trauma associated with liver and intestinal injuries, to avoid the need for more complex procedures. In addition, it demonstrates postoperative management of complications, including confection of the enteroatmospheric fistula for feeding. CONCLUSION: The technique described in this article proved to be a good option for treating these lesions, as evidenced by optimal postoperative results.
