title: Predictors of chest drainage complications in trauma patients

description: ABSTRACT Objective: to identify predictors of chest drainage complications in trauma patients attended at a University Hospital. Methods: we conducted a retrospective study of 68 patients submitted to thoracic drainage after trauma, in a one-year period. We analyzed gender, age, trauma mechanism, trauma indices, thoracic and associated lesions, environment in which the procedure was performed, drainage time, experience of the performer, complications and evolution. Results: the mean age of the patients was 35 years and the male gender was the most prevalent (89%). Blunt trauma was the most frequent, with 67% of cases, and of these, 50% were due to traffic accidents. The mean TRISS (Trauma and Injury Severity Score) was 98, with a mortality rate of 1.4%. The most frequent thoracic and associated lesions were, respectively, rib fractures (51%) and abdominal trauma (32%). The mean drainage time was 6.93 days, being higher in patients under mechanical ventilation (p=0.0163). The complication rate was 26.5%, mainly poor drain positioning (11.77%). Hospital drainage was performed in 89% of cases by doctors in the first year of specialization. Thoracic drainage performed in prehospital care presented nine times more chances of complications (p=0.0015). Conclusion: the predictors of post-trauma complications for chest drainage were a procedure performed in an adverse site and mechanical ventilation. The high rate of complications demonstrates the importance of protocols of care with the thoracic drainage.

title: Inflammatory and nutritional statuses of patients submitted to resection of gastrointestinal tumors

description: ABSTRACT Objective: to evaluate the association between the nutritional and the inflammatory statuses of patients with cancer of the gastrointestinal tract undergoing surgical resection and to identify predictors of mortality in these patients. Methods: we conducted a prospective study of 41 patients with gastrointestinal tract cancer submitted to surgery between October 2012 and December 2014. We evaluated the nutritional status by subjective and objective methods. We assessed the inflammatory response and prognosis using the modified Glasgow Prognostic Score (mGPS), Neutrophil/Lymphocyte Ratio (NLR), Onodera Prognostic Nutritional Index (mPNI), Inflammatory-Nutritional Index (INI) and C-Reactive Protein/Albumin ratio (mPINI). Results: half of the patients were malnourished and 27% were at nutritional risk. There was a positive association between the percentage of weight loss (%WL) and the markers NLR (p=0.047), mPINI (p=0.014) and INI (p=0.015). Serum albumin levels (p=0.015), INI (p=0.026) and mPINI (p=0.026) were significantly associated with the PG-SGA categories. On multivariate analysis, albumin was the only inflammatory marker independently related to death (p=0.004). Conclusion: inflammatory markers were significantly associated with malnutrition, demonstrating that the higher the inflammatory response, the worse the PG-SGA (B and C) scores and the higher the %WL in these patients. However, further studies aimed at improving surgical outcomes and determining the role of these markers as predictors of mortality are required.

title: Use of an algorithm in choosing abdominoplasty techniques

description: ABSTRACT Objective: to validate an algorithm for the choice of the abdominoplasty surgical technique among the five approaches established in the literature, according to the characteristics of the abdominal wall. Methods: we conducted a retrospective study of 245 patients undergoing abdominoplasty, for whom the method of choice of the surgical technique was the proposed algorithm, based on the degree of abdominal flaccidity determined by bimanual maneuver. We studied its applications and conveniences, as well as the complications inherent in each group studied. Results: according to the algorithm used, the most frequently chosen technique was “Technique IV” (transverse dermolipectomy of Pitanguy - or with a Baroudi-Kepke incision), in 25.71% of the cases. “Technique I” (mini abdominoplasty) had the lowest incidence and the lowest rate of complications. On the opposite, “Technique III”, dermolipectomy with remaining vertical scarring, presented a higher incidence of complications, requiring extreme caution in its indication, particularly in relation to patients’ expectations regarding the resulting scar and its legal aspects. Among all conducts, the most frequent complication was seroma, with a 10.2% occurrence, solved by simple syringe aspiration and use of elastic compression mesh. Conclusion: the proposed algorithm facilitated the choice of abdominoplasty techniques, offering satisfactory results, which are in line with the complication rates published in the world literature.

title: Hemodynamic evaluation of elderly patients during laparoscopic cholecystectomy

description: ABSTRACT Objective: to demonstrate hemodynamic changes during laparoscopic cholecystectomy in elderly patients with trans-esophageal echocardiography. Methods: we studied 31 elderly patients (aged 60 years or older), ASA I or II, who underwent elective laparoscopic cholecystectomy under general, standardized anesthesia, with cardiovascular parameters measured using transesophageal echocardiography at three different times: before the pneumoperitoneum (T1), after CO2 insufflation (T2) and at deflation (T3). We statistically evaluated changes in systolic, diastolic and mean blood pressure, heart rate, cardiac output and index, and ejection fraction. Results: although small, only the diastolic blood pressure (DBP) and ejection fraction (EF) variations were statistically significant. The mean ± standard deviation of DBP in mmHg at the different times were: T1=67.5±10.3; T2=73.6±12.4; and T3=66.7±9.8. And for EF, in percentage (%) they were: T1=66.7±10.4; T2=63.2±9.9; and T3=68.1±8.4. There was no statistical correlation between hemodynamic variations, age and number of patients’ comorbidities. Conclusion: laparoscopic cholecystectomy causes few hemodynamic changes that are well tolerated by the majority of the elderly patients; prior impairment of ventricular function represents a threat in elderly patients during surgery; there appears to be a lower hemodynamic effect caused by the pneumoperitoneum than by the patient’s positioning in a reverse Trendelemburg during surgery.

title: Primary umbilical endometriosis

description: ABSTRACT Objective: to report the characteristics, evolution and outcome of patients with primary umbilical endometriosis. Methods: an observational and descriptive study of patients with primary umbilical endometriosis diagnosed between 2014 and 2017. The clinical variables evaluated were age, clinical picture, lesion characteristics, diagnostic methods, treatment and recurrence. Results: six patients diagnosed with primary umbilical endometriosis aged 28 to 45 years were operated on during the study period. They had lesions ranging from one to 2.5cm in diameter, violet in five patients and erythematous-violaceous in one. The duration of the symptoms until diagnosis ranged from one to three years and in all the cases studied the diagnosis was made through the clinical manifestations and confirmed by histopathological analysis. No case was associated with neoplastic alterations. All patients evaluated had pain and umbilical bleeding in the menstrual period. Conclusion: umbilical endometriosis is an uncommon disease and should be included in the differential diagnosis of women as umbilical nodules. The treatment of choice is the total exeresis of the lesion.

title: Evaluation of arboviruses of public health interest in free-living non-human primates (Alouatta spp., Callithrix spp., Sapajus spp.) in Brazil

description: INTRODUCTION: The aim of the present study was to evaluate the presence of arboviruses from the Flavivirus genus in asymptomatic free-living non-human primates (NHPs) living in close contact with humans and vectors in the States of Paraná and Mato Grosso do Sul, Brazil. METHODS: NHP sera samples (total n = 80, Alouatta spp. n = 07, Callithrix spp. n = 29 and Sapajus spp. n = 44) were screened for the presence of viral genomes using reverse transcription polymerase chain reaction and 10% polyacrylamide gel electrophoresis techniques. RESULTS: All of the samples were negative for the Flavivirus genome following the 10% polyacrylamide gel electrophoresis analysis. CONCLUSIONS: These negative results indicate that the analyzed animals were not infected with arboviruses from the Flavivirus genus and did not represent a risk for viral transmission through vectors during the period in which the samples were collected.

title: Pulmonary metastases in children: are we operating unnecessarily?

description: ABSTRACT Objective: to determine, in pediatric patients with malignant neoplasms, the characteristics of pulmonary nodules identified on computed tomography, as well as the possibility of differentiating benign lesions from metastases. Methods: we conducted a retrospective study of patients submitted to pulmonary resections of nodules diagnosed as metastases in a period of seven years. We compared computed tomography and surgery findings, as well as results of anatomopathological examinations. Results: we studied nine patients submitted to 11 surgical interventions. Among the studied variables, only nodule size greater than 12.5mm proved to be statistically significant to predict malignancy. Conclusion: among the tomographic characteristics of pulmonary nodules in children with malignant neoplasms, only the size of the lesion was a predictor of malignancy.

title: Evaluation of natural foci of Panstrongylus megistus in a forest fragment in Porto Alegre, State of Rio Grande do Sul, Brazil

description: Introduction Panstrongylus megistus is commonly found in wild environments of the State of Rio Grande do Sul, Brazil. The aim of this study was to characterize the network of refuges used by triatomine in a forest fragment of Porto Alegre and to identify Trypanosoma cruzi infection, associated hosts and the epidemiological importance of both hosts and triatomines. Methods Techniques including the spool-and-line method and active searching (transects) were used to identify natural foci. Results The food source for each triatomine was determined using the precipitin test, and the infection of marsupials was determined by xenodiagnosis. A total of 33 adults (domestic environment) and 27 nymphs (wild environment) of P. megistus were found in addition to 43 Didelphis albiventris specimens. The infection rates of triatomine adults, triatomine nymphs and opossums with T. cruzi I were 64%, 73% and 69%, respectively. Birds, rodents and opossums were the main resources used by triatomine. Conclusions This work presents the first characterization of a natural focus of P. megistus in Rio Grande do Sul. The natural characteristics of this focus and its implication in the transmission of T. cruzi are discussed.

title: Topical hemostatic agents in surgery: review and prospects.

description: ABSTRACT Hemostasis plays a critical and fundamental role in all surgical procedures. Its management has several key points that start with good operative technique and adequate anesthetic support. Certain situations, such as severe bleeding resulting from penetrating trauma, do not depend exclusively on the control of the surgical team and require the support of new solutions that decrease or control bleeding. Since ancient times, a hallmark of medicine has been to act in the control of hemorrhage, and more recently, in the facilitation of hemostasis by the application of topical agents by either manual compression or modern agents. In the last decade, the number of different topical hemostatic agents has grown dramatically. For the modern surgeon to choose the right agent at the right time, it is essential that he/she understands the mechanisms of action, the effectiveness and the possible adverse effects related to each agent. Thus, the great variety of topical hemostatics, coupled with the absence of a review article in the national literature on this topic, stimulated us to elaborate this manuscript. Here we report a detailed review of the topical hemostatic agents most commonly used in surgical specialties.

title: Cardiac tamponade by peripherally inserted central catheter in preterm infants: role of bedside ultrasonography and therapeutic approach.

description: ABSTRACT Objective: to determine the incidence of pericardial effusion with cardiac tamponade in preterm infants in a pediatric intensive care unit, with emphasis on the relationship between pericardial effusion and peripherally inserted central catheter, and to evaluate the role of bedside ultrasound in approaching these cases. Methods: we conducted a retrospective analysis of patients admitted to a pediatric intensive care unit between July 2014 and December 2016, who presented pericardial effusion with hemodynamic repercussion, evaluated by ultrasonography. Results: we studied 426 patients admitted to the five beds of the neonatal unit. In the period, there were 285 bedside ultrasound exams. We found six cases of pericardial effusion, four of which with obstructive shock and need for pericardial drainage. There was no procedure-related mortality, and all patients evolved with hemodynamic improvement after the procedure. The incidence of pericardial effusion was 2.4 cases per year. Conclusion: the incidence of pericardial effusion is low in neonates, but early diagnosis is fundamental due to high morbidity and mortality, especially in cases of abrupt onset. All cases were diagnosed by bedside ultrasonography, demonstrating its importance in the screening of these cases, especially in shocks of uncertain etiology and neonates with sudden onset hemodynamic instability who are using central venous access.
