title: Orthopedic and ultrasound assessment of hip stability of newborns referred by pediatricians with suspected Developmental Dysplasia.

description: ABSTRACT Objective: to evaluate newborns with suspected hip instability, referred by pediatricians to a tertiary orthopedic service. Methods: newborns from a public university maternity hospital, with suspected instability or risk factors for hip dysplasia, were referred to the Department of Orthopedics and Anesthesiology, Ribeirão Preto/SP, where we evaluated them clinically and through ultrasound examinations of the hips. Once we found dysplasia, we initiated treatment, and in cases in which there was only hip immaturity and normal clinical examination, we performed clinical and ultrasound observation and review at two or three months of age. Results: we examined 448 newborns, with female predominance and average age at first evaluation of 27 days. The main cause of referral was pelvic presentation at delivery. In 8% there was a positive Ortolani sign and in 12.5%,. At orthopedic examination, 405 (90.5%) patients were normal, 8.5% had hip click and 1.1% had positive Ortolani test. At ultrasound, 368 (89.5%) had immaturity, 26 (6.3%) had moderate dysplasia and in 17 (4.1%) patients the hips were frankly dysplastic. All cases with positive Ortolani sign showed dysplasia at ultrasound. Conclusion: there was an excess diagnosis of hip instability in the pediatrician evaluation, which, however, allowed the patient a second assessment, in a more specialized environment and with more technological resources.

title: Outcomes prediction score for acute abdomen: a proposal.

description: ABSTRACT Objective: to establish a correlation between objective data collected at the initial evaluation and the outcomes in cases of acute abdominal pain. Methods: we conducted a retrospective, case-control study in which we reviewed medical records of patients treated at an emergency room in 2016, diagnosed with abdominal and pelvic pain. Results: of the 2,352 medical records evaluated, we considered 330 valid for the study. Of these patients, 235 (71.2%) were discharged and the remaining 95 (28.8%) were hospitalized, submitted to surgery, or died. The statistical analysis demonstrated that male gender, age ≥50, axillary temperature &gt;37.3ºC, anemia, leukocytosis &gt;10,000/mm3, neutrophil count above 7,700/mm3, lymphocyte count less than 2,000/mm3 and hyperamylasemia were variables in independently associated with worse outcome. Conclusion: the presence of three or more of the evaluated variables greatly increases the chances of a patient suffering the outcomes of surgery or death, the chance of death being greater the greater the number of variables present.

title: Preoperative laparoscopy and peritoneal lavage in gastric adenocarcinoma: can the approach be modified?

description: ABSTRACT Objective: to assess whether laparoscopy with peritoneal lavage is superior to computed tomography for staging gastric adenocarcinoma and whether it can modify the surgical approach. Methods: we conducted a retrospective study of 46 patients with gastric adenocarcinoma treated by the digestive surgery team of the Passo Fundo Clinics Hospital (RS), from January 2015 to December 2018, and submitted to laparoscopy with preoperative peritoneal lavage. All patients underwent preoperative clinical staging with computed tomography. Results: of the 46 patients analyzed, the majority had tumors located in the cardia (34.8%), poorly differentiated (69.6%), and subtype signet ring cells (65.2%). In 91.3%, the computed tomography scan did not identify peritoneal carcinomatosis or distant metastasis. Among these patients with negative computed tomography for distant disease, 21.8% had positive peritoneal lavage for neoplastic cells and had their therapeutic approaches modified. Conclusion: laparoscopy and peritoneal lavage altered the surgical decision in 21.8% of patients, providing a more reliable preoperative staging in gastric adenocarcinoma.

title: Effects of arginine on abdominal wall wound healing in Wistar rats.

description: ABSTRACT Objective: to evaluate the effects of arginine on abdominal wall healing in rats. Methods: we submitted 20 Wistar rats to laparotomy and divided them into two groups, arginine and control, which then received, respectively, daily intraperitoneal treatment with arginine (300mg/kg/day) and weight-equivalent phosphate buffered solution, during five days. On the seventh postoperative day, we collected blood and scar wall samples from both groups. We evaluated serum nitrate and nitrite levels, wound evolution by tissue hydroxyproline dosages, granulation tissue formation, percentage of mature and immature collagen, myofibroblast density and angiogenesis. We used the ANOVA and the Student’s t tests with p=0.05 for comparisons between groups. Results: there were no significant differences between the groups studied for nitrate and nitrite (p=0.9903), tissue hydroxyproline (p=0.1315) and myofibroblast density (p=0.0511). The arginine group presented higher microvascular density (p=0.0008), higher percentage of type I collagen (p=0.0064) and improved granulation tissue formation, with better angiofibroblastic proliferation rates (p=0.0007) and wound edge reepithelization (p=0.0074). Conclusion: in the abdominal wall healing evaluation of Wistar rats under arginine treatment, there was no change in serum nitrate and nitrite levels, total collagen deposition and myofibroblast density. There was an increase in type I collagen maturation, microvascular density and improvement in scar granulation tissue formation by better edge reepithelization and angiofibroblastic proliferation.

title: Predictive factors of low anterior resection syndrome following anterior resection of the rectum.

description: ABSTRACT Objective: to identify predictors of low anterior resection syndrome (LARS) that can contribute to its early diagnosis and treatment. Methods: we conducted a retrospective cohort study of patients undergoing anterior resection of the rectum between 2007 and 2017 in the Coloproctology Service of the Federal University of Parana Clinics Hospital. We performed Receiver Operating Characteristic Curve (ROC) analysis to identify LARS predictive factors. Results: we included 64 patients with complete data. The men's age was 60.1±11.4 years and 37.10% were male. Twenty patients (32.26%) had LARS. The most reported symptoms were incomplete evacuation (60%) and urgency (55%). In the univariate analysis, the distance from the anastomosis to the anal margin (p&lt;0.001), neoadjuvant therapy (p=0.0014) and ileostomy at the time of resection (p=0.0023) were predictive of LARS. The ROC curve analysis showed a 6.5cm cut-off distance from the anastomosis to the anal margin as a predictor of LARS. Conclusion: distance between the anastomosis and the anal margin, neoadjuvant therapy history and preparation of stoma are conditions that can help predict the development of LARS. Guidance and involvement in patient education, as well as early management, can potentially reduce the impact of these symptoms on patients' quality of life.

title: Comparative incidence of incidental gallbladder cancer in emergency cholecystectomies versus in elective cholecystectomies.

description: ABSTRACT Objective: to comparatively analyse the incidence of incidental gallbladder cancer in emergency cholecystectomies versus in elective cholecystectomies performed in public hospitals in Teresina city, Piaui state (PI). Methods: descriptive, quantitative, observational, cross-sectional study, whose scenarios were two public hospitals in Teresina-PI. We analysed 6,329 medical records of patients undergoing cholecystectomy between January 2011 and December 2017. The collected data were divided into two groups and statistically compared using Z-test for difference between proportions. Results: incidental gallbladder cancer was detected in 6.53% of emergency cholecystectomies and in 0.38% of elective ones. Regarding gender, it was observed that in emergency surgeries 69% of patients were women and 31% men, while in elective procedures 78% were women and 22% men. Regarding age, most patients were over 60 years old, and, among these, 69.3% underwent emergency cholecystectomies and 82.6% underwent elective cholecystectomies. The histopathological type “adenocarcinoma” was found in 84.6% of patients who underwent emergency surgeries and in 100% of patients who underwent elective surgeries. Conclusion: incidental gallbladder cancer was more frequent in urgent cholecystectomies compared to elective cholecystectomies. The profile of patients with this malignant disease in both types of procedure was female, older than 60 years, and with histopathological diagnosis of adenocarcinoma.

title: Effects of vasoconstrictor use on digital nerve block: systematic review with meta-analysis

description: ABSTRACT Conventionally, the association of local anesthetics with vasoconstrictors is avoided at extremities due to the risk of ischemia. However, recent studies suggest that there is safety in the use of vasoconstrictors at extremities. Thus, we sought to evaluate the effectiveness and safety of vasoconstrictor use combined with local anesthetics in digital nerve block compared to the use of anesthetics without vasoconstrictors, through a systematic review with meta-analysis of randomized clinical trials. Until May 2019 we searched MEDLINE, LILACS, SciELO, ScienceDirect, Scopus, ClinicalTrials.gov, and gray literature databases, without date or language restrictions. The keywords were the following: digital block, vasoconstrictor, and ischemia. We included randomized clinical trials in which there was the use of local anesthetics with associated or not with vasoconstrictors in digital blocks. In the primary variables, the occurrence of ischemic complications and the duration of anesthesia were analysed; in the secondary variables, the need for anesthetic reapplication, bleeding control, and latency were observed. Ten studies were included in this review. The occurrence of ischemia was not observed, regardless of the use of vasoconstrictors or not. The use of vasoconstrictors at a concentration of 1:100,000 or less was associated with longer anesthesia duration (P&lt;0.00001), lower need for anesthetic reapplication (P=0.02), lower need for bleeding control (P=0.00006), and lower latency (P&lt;0.00001). We could conclude that the use of vasoconstrictors associated with local anesthetics in digital block proved to be a safe and effective technique.

title: The surgeons and the COVID-19 pandemic.

description: ABSTRACT The current world Covid-19 pandemic has been the most discussed topic in the media and scientific journals. Fear, uncertainty, and lack of knowledge about the disease may be the significant factors that justify such reality. It has been known that the disease presents with a rapidly spreading, it is significantly more severe among the elderly, and it has a substantial global socioeconomic impact. Besides the challenges associated with the unknown, there are other factors, such as the deluge of information. In this regard, the high number of scientific publications, encompassing in vitro, case studies, observational and randomized clinical studies, and even systematic reviews add up to the uncertainty. Such a situation is even worse when considering that most healthcare professionals lack adequate knowledge to critically appraise the scientific method, something that has been previously addressed by some authors. Therefore, it is of utmost importance that expert societies supported by data provided by the World Health Organization and the National Health Department take the lead in spreading trustworthy and reliable information. The Brazilian College of Surgeons suggests in this document various initiatives that may help surgeons, healthcare providers, and patients who will have to face a surgical event under the pandemic.
