RESUMO

BACKGROUND: Enhanced Recovery After Surgery (ERAS) protocols are well-documented logistic programs in elective surgery but it is still uncertain whether ERAS can benefit emergency patients, because of significant challenges facing its application to emergency surgery. The aim of this study was to evaluate the implementation of an ERAS protocol for patients with acute appendicitis (AA), both complicated and uncomplicated. METHODS: A prospective observational study was performed at two university hospitals in Spain, between January 2012 and December 2019. Inclusion criteria were patients with diagnosis of AA, undergoing appendectomy following an ERAS protocol of perioperative care. The different items of the ERAS protocol were recorded and their implementation was separately evaluated. Analyzed variables also included postoperative complications, hospital stay and readmission rate. Levels of acute phase reactants were assessed as predictors of implementation for the ERAS protocol. RESULTS: Eight hundred fifty patients were included; 498 males (58.5%) and 302 females (41.5%), with a mean age of 34.95 ± 17 years. The implementation of all the items of the protocol was achieved in 770 patients (90.6%), 86.8% of patients with complicated AA and 93.1% of patients with uncomplicated AA (p = 0.02). Higher preoperative C-reactive protein (CRP) levels were significantly associated with the impossibility of implementing all the items of the ERAS protocol (p < 0.001), establishing a cut-off point at CRP = 13.5 mg/dl. CONCLUSIONS: The implementation of ERAS protocols is safe and feasible in patients with AA. Although the implementation rate of all the items is lower in patients with complicated AA, it can be completed in 86.8% of these patients. CRP levels over 13.5 mg/dl are predictors of difficulties in the implementation of all the items of ERAS protocols.

RESUMO

AIM: To evaluate if the redox system is unbalanced in the hearts of nitrofen-induced congenital diaphragmatic hernia  (CDH) animals and to study the possible preventive effects of two anti-oxidant treatments, apocynin and epigallocatechin-3-gallate (EGCG). METHODS: Adult rats were divided into four groups. Group 1: rats received only vehicle on day E9.5. Group 2: rats received 100 mg nitrofen on day E9.5. Group 3: 1 month before mating rats received apocynin 1.5 mM and, when pregnant, 100 mg nitrofen on day E9.5. Group 4: same than group 3 but with EGCG 30 mg/kg. All fetuses were recovered at term and the hearts were processed. Nox activity and mRNA levels of Nox1, Nox2, Nox4, SOD1, SOD2, SOD3, catalase, and GPX1 were analyzed. Nox, SOD, and Catalase activity and H2O2 production were also evaluated. RESULTS: Nox activity, H2O2 production and Nox1, Nox2, and Nox4 mRNA levels were increased in the hearts of fetuses with CDH. There were no changes in SOD1 levels, whereas those of SOD2, SOD3, catalase, and GPX1 mRNA were decreased. Apocynin and EGCG treatments attenuated the increment of Nox and SOD activities and H2O2 production was only decreased by apocynin. CONCLUSION: These findings suggest a possible preventive effect on the abnormal redox metabolism of anti-oxidant treatments in the hearts from rat fetuses with CDH. If the same occurs in humans, it could represent a potential tool in future prenatal treatment.

RESUMO

BACKGROUND AND PURPOSE: Enlarged perivascular spaces (EPVS) have been recently considered a feature of cerebral small vessel disease. They have been related to aging, hypertension and dementia but their relationship with hypertension related variables (i.e. target organ damage, treatment compliance) and mild cognitive impairment (MCI) is not fully elucidated. Our aims were to investigate the relation between basal ganglia (BG) and centrum semiovale (CSO) EPVS with vascular risk factors, hypertension related variables and MCI. METHODS: In all, 733 hypertensive individuals free of stroke and dementia from the Investigating Silent Strokes in Hypertensives, a magnetic resonance imaging Study (ISSYS) underwent brain magnetic resonance imaging and cognitive testing to diagnose MCI or normal cognitive aging. RESULTS: The numbers of participants presenting high grade (>10) EPVS at the BG and CSO were 23.3% and 40.0%, respectively. After controlling for vascular risk factors, high grade BG EPVS were associated with age (odds ratio 1.68; 95% confidence interval 1.37, 2.06), poor antihypertensive compliance (1.49; 1.03, 2.14) and the presence of microalbuminuria (1.95; 1.16, 3.28), whereas in the CSO only age (1.38; 1.18, 1.63) and male sex were associated with EPVS (1.73; 1. 24, 2.42). MCI was diagnosed in 9.3% of the participants and it was predicted by EPVS in the BG (1.87; 1.03, 3.39) but not in the CSO. This last association was greatly attenuated after correction for lacunes and white matter hyperintensities. CONCLUSIONS: Basal ganglia EPVS are associated with the presence of microalbuminuria and poor adherence to antihypertensive drugs. The BG EPVS relation with MCI is not independent of the presence of other cerebral small vessel disease markers.

RESUMO

PURPOSE: Congenital diaphragmatic hernia (CDH) is one of the causes of respiratory failure in newborns due to lung hypoplasia and pulmonary abnormalities leading to pulmonary hypertension (PH). NAD(P)H oxidase (Nox) is a family of isoenzymes that generate reactive oxygen species (ROS) which can contribute to PH-induced vascular dysfunction. On the other hand, superoxide dismutase (SOD) 1-2 and catalase are the antioxidant enzymes that eliminate the excess of ROS in pulmonary vascular cells. Our aim is to examine whether PH-associated with CDH is due to a dysregulation of ROS production in lungs from CDH fetuses. METHODS: Pregnant rats received either 100 mg nitrofen or vehicle on E9.5. Fetuses were recovered on E21. (1) Nox activity, (2) H2O2 production and (3) mRNA levels of Nox1, Nox2, Nox4, SOD1, SOD2 and catalase were analyzed in fetal lungs. RESULTS: Nox activity and Nox1 and Nox2 mRNA levels were increased in the lungs of fetuses with CDH. However, there were no changes in H2O2 production and Nox4 mRNA levels. SOD1, SOD2 and catalase were decreased. CONCLUSIONS: The raised oxidative stress due to increase in ROS generation by Nox isoenzymes and dysfunction of antioxidant enzymes seems to be a potential mechanism responsible on PH-associated with CDH.

RESUMO

OBJECTIVES: This European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) position statement provides a comprehensive guide for health care providers to manage percutaneous endoscopic gastrostomy tubes in a safe, effective, and appropriate way. METHODS: Relevant literature from searches of PubMed, CINAHL, and recent guidelines was reviewed. In the absence of evidence, recommendations reflect the expert opinion of the authors. Final consensus was obtained by multiple e-mail exchange and during 3 face-to-face meetings of the gastroenterology committee of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition. RESULTS: Endoscopically placed gastrostomy devices are essential in the management of children with feeding and nutritional problems. The article focuses on practical issues such as indications and contraindications. CONCLUSIONS: The decision to place an endoscopic gastrostomy has to be made by an appropriate multidisciplinary team, which then provides active follow-up and care for the child and the device.

RESUMO

To determine HRQOL after pediatric intestinal transplantation. Thirty-four IT survivors from 1999 to 2012 were asked to complete age-specific HRQOL non-disease-specific questionnaires: TAPQOL (0-4 yr), KINDL-R (5-7 yr; 8-12 yr; 13-17 yr), and SF-36v2 (>18 yr), all validated with Spanish population. Primary caregiver completed a SF-36 questionnaire and CBI. Thirty-one participants were included. Median age was 10.2 yr (1-29) and time after transplant 4.4 yr (0-13). Overall patient scores were 78.2 ± 10.6 (n = 8), 83.3 ± 9.7 (n = 6), 72.2 ± 9.21 (n = 6), 80.5 ± 12.4 (n = 7), and 82.2 ± 12.4 (n = 4) for each age group. Highest scores were obtained for vitality (group I), self-esteem (group IV), and physical and social functioning and emotions (group V). Lowest scores were obtained in appetite and behavior (I), family and school (III), and chronic disease perception (III, IV). No significant differences were found between caregivers and their children. CBI showed stress in 52%. SF-36 for caregivers was lower than general population. No significant differences were found depending on relevant clinical and sociodemographic data. HRQOL was acceptable and improved with age and time since transplantation. Parents had a slighter own QOL and worse perception of health than their children. When successful, intestinal transplantation allows a normal life in most patients and can be offered as an attractive option.

RESUMO

AIM: Previous studies on percutaneous posterior tibial nerve stimulation (PTNS) for faecal incontinence do not report anal pressure changes. In the present study the effect of percutaneous PTNS on anal manometry was determined. METHOD: This was a prospective observational study of patients with faecal incontinence. They underwent one 30-min session of PTNS weekly for 12 consecutive weeks. Patients who showed improvement were given six more sessions at 2-weekly intervals. Anal manometry was performed before and after treatment. Clinical data including the Wexner score, psychological testing, quality of life using the Fecal Incontinence Quality of Life Score and the contents of a continence diary were recorded before and after the procedure. RESULTS: Twenty-four patients were included in the study of whom 17 (70.83%) demonstrated some degree of clinical or manometric improvement at 3 months. Before treatment 18 patients had urgency of <1 min. At 3 and 6 months this had risen to 5 min in 62.5% and 70.83% (P < 0.001). The anal resting pressure increased from 21.7 to 37.6 mmHg (P = 0.021), the maximum squeeze pressure from 58.2 to 72.2 mmHg (P = 0.045) and the Wexner score fell from 15 to 10 (P = 0.018) at 6 months. Predictive factors for a response included fewer than three incontinent episodes per week (P = 0.027). Negative predictive factors included episiotomy and an initial Wexner score of > 12 (P = 0.035). CONCLUSION: Percutaneous PTNS was effective in over 70% of patients in the present study with improvements in urgency, anal pressures and Wexner score.

RESUMO

INTRODUCTION: Peutz-Jeghers-type hamartomatous polyps are most common in the small intestine, but can also occur in the stomach and large bowel. Gastric polyps usually coexist with hamartomatous polyps in other locations of the gastro-intestinal tract. We present the second case reported in literature of diffuse gastric polyposis without affecting the rest of the gastrointestinal tract. CASE REPORT: A 41-years-old woman complained of repeated, self-limited episodes of hematemesis. She presented with anaemia. An upper gastrointestinal endoscopy revealed multiple polyps in all the gastric surface, whose biopsy diagnosed of hamartomatous polyps. No other polyps were detecting the gastrointestinal tract. The patient underwent a total gastrectomy with Roux-en-Y reconstruction. Pathology revealed a gastric diffuse hamartomatous polyposis. A mis-sense mutation encoding the serine/threonine kinase STK11 gene was been identified, compatible with Peutz Jeghers polyposis.

RESUMO

BACKGROUND/AIM: Neither cervicotomy nor postero-lateral thoracotomy allow safe surgical access to the lower cervical spine and high posterior mediastinum with full control of the vascular and neural structures involved. We report our favorable experience with cervico-sternotomy for accessing this region. PATIENTS AND METHODS: Six patients were operated upon between 1998 and 2011 for either removal of huge cervico-thoracic neural ganglioneuromas (n = 2) or anterior arthrodesis for congenital (n = 2), neuropathic (n = 1) or osteolytic scoliosis (n = 1). In all cases, cervicotomy was followed by sternotomy, thymectomy, division of the innominate vein and dissection of jugular veins, carotid arteries and vagus nerves. RESULTS: The tumors measured 10.9 x 3.9 x 8.7 cm and 8 x 6 x 5 cm, and involved the paravertebral chain from the aortic arch to the base of the skull and from the left lung hilus to the thyroid region respectively. In the scoliosis patients, anterior vertebral fixation between C5 and T5 was readily feasible. Blood transfusion was avoided. Horner's syndrome and transient lymphedema were the only complications. Median operative time was 210 minutes (range 180-240 minutes) and median estimated blood loss was 2.7 cc/kg (0-13.8 cc/kg). Median hospital stay was 7 days (range 5-18 days). CONCLUSIONS: Cervico-sternotomy is an optimal approach for this anatomical region in children. It offers better exposure of the anterior cervico-thoracic spine and the thoracic inlet than cervicotomy or thoracotomy. Control of the nervous and vascular structures was safely achieved in all cases and postoperative discomfort was surprisingly limited.

RESUMO

Gastroesophageal reflux (GER) is almost constant in esophageal atresia and tracheoesophageal fistula (EA/TEF). These patients resist medical treatment and require antireflux surgery quite often. The present review examines why this happens, the long-term consequences of GER and the main indications and results of fundoplication in this particular group of patients. The esophagus of EA/TEF patients is malformed and has abnormal extrinsic and intrinsic innervation and, consequently, deficient sphincter function and dysmotility. These anomalies are permanent. Fifty percent of patients overall have GER, and one-fifth have Barrett's metaplasia. Close to 100%, GER of pure and long-gap cases require fundoplication. In the long run, these patients have 50-fold higher risk of carcinoma than the control population. GER in EA/TEF does not respond well to dietary, antacid, or prokinetic medication. Surgery is necessary in protracted anastomotic stenoses, in pure and long-gap cases, and when there is an associated duodenal atresia. It should be indicated as well in other symptomatic cases when conservative treatment fails. However, confection of a suitable wrap is anatomically difficult in this condition as shown by a failure rate of 30% that is also explained by the persistence for life of the conditions facilitating GER.

RESUMO

PURPOSE: Embryonal sarcoma accounts for 6 % of liver tumors. This study reviews its features and the results of treatment in a referral center. METHODS: We retrospectively reviewed liver tumors treated between 1995 and 2011. PRETEXT staging and biopsy were used to tailor chemotherapy according to SIOP protocols. Radical surgery was performed when possible. Complications and cumulative survival were the outcome endpoints. RESULTS: Six out of 156 primary liver tumors (four males and two females) were sarcomas. The mean age at diagnosis was 81 ± 8.5 months. The most frequent finding was abdominal mass. Alfa-fetoprotein was normal. Imaging depicted heterogeneous tumors with septa, necrosis, and hemorrhagic areas. The diagnosis was ascertained by biopsy. Three tumors were located in the right lobe (PRETEXT II): two were bilobar (PRETEXT III) and one was in the left lobe (PRETEXT I). Two children had metastases at diagnosis and high-risk chemotherapy (vincristine, carboplatin, epirubicin) was administered with poor response. They died without operation 4 and 10 months later. Four patients with local disease underwent typical liver resections after chemotherapy (iphosphamide, vincristine, actinomycin D, and doxorrubicin). Overall actuarial survival at 70 months was 66.6 %. CONCLUSIONS: Extended and metastatic embryonal sarcoma do poorly whereas localized tumors amenable to complete surgical removal after chemotherapy can cure.

RESUMO

To compare intraocular pressure (IOP) measurements obtained with Goldmann applanation (GAT) and dynamic contour tonometry (DCT) in a Mexican population. 40 glaucoma patients were included in this cross-sectional observational cohort study. IOP measurements were performed in the following order: DCT, ultrasonic pachymetry and GAT, with a 5-minute difference between each measurement, between 8 am and 2 pm. Only DCT measurements of good quality (Q ≤ 3) were accepted. GAT measurements were made three times with the same Goldmann tonometer, previously checked for calibration errors, and the mean was used for statistical purposes. The IOP (mean [standard deviation], 95 % confidence interval [CI]) measured with the Goldmann tonometer (13.2 [2.4], 12.4-14.0 mmHg) was significantly lower than that obtained with the DCT (18.4 [3.3], 17.0-19.2 mmHg), p < 0.0001. Pearson's correlation coefficients between CCT and IOP measured with GAT and DCT were (r = 0.24, 95 % CI = 0.07-0.52, p = 0.133) and (r = 0.13, 95 % CI = -0.19 to 0.43, p = 0.412), respectively. The concordance correlation coefficient between GAT and DCT was r c = 0.3, 95 % CI = 0.17-0.41). DCT seems to overestimate the IOP as compared to GAT. Additionally, although there was a good correlation between the IOP measurements assessed with either GAT or DCT, the agreement was poor.

RESUMO

PURPOSE: Our objective is to describe a new experimental model of amniotic band in rats and to show the initial morphological results. METHODS: The model was created by ligation of a hind limb with silk on day 17 of gestation; in selected fetuses ligation was withdrawn on day 19 of gestation. Fetuses were removed by cesarean section on day 21 of gestation, analyzing their weights and morphological characteristics of their hind legs. We used 10 pregnant SD rats, weighing 263 g (231-279). One hundred and thirteen fetuses were analyzed divided into 6 groups: fetuses from control rats (n=28), uterine opening and closing (n=7), band creation (n=28), band creation and subsequent removal (n=14) and not intervened fetuses of the litters in which the band was created (n=19) and that the band was created and removed (n=17). Comparisons between groups were made using parametric tests considering p<0.05 as a threshold for significance. RESULTS: Operated fetuses (band creation and band creation and removal) showed statistically significant differences in weight (mean=4.56 g and 4.4 g) and length of their hind limbs (mean=3.97 mm and 5.34 mm) compared to the rest of the groups. The rate of abortions in operated fetuses was 16.6% and the rate of amputations was 8.3%. DISCUSSION: A viable and reproducible experimental model of amniotic band is described, with potential applications in both the study of the disease and the role of fetal surgery thereon.

RESUMO

Using telehealth as a mode of service delivery has the potential to address some long-standing challenges in early intervention (EI) services such as waiting lists to access services. Yet, little is known about parent perceptions of telehealth in EI based on their lived experiences partnering with EI practitioners. The purpose of this study was to explore parent perceptions on using telehealth, especially on family-professional partnerships and coaching. Interviews were conducted with 15 parents of children receiving EI services via telehealth from June to August of 2021. Almost half of the participants reflected under-represented racial and ethnic backgrounds. Constant comparative analysis and emergent coding were used for data analysis. The findings showed that the advantages outnumbered the disadvantages regarding telehealth. Participants reported that telehealth provided a safe and flexible option and eliminated the wait to access EI services. However, participants identified some disadvantages to telehealth including telehealth precluded substantive interactions with therapists and limited access to technology. The findings also indicated that telehealth enhanced family-professional partnerships. Nearly all participants valued coaching during telehealth. Participants suggested initial supports to facilitate EI via telehealth, including stable internet access, telehealth training, and an initial in-person visit. Implications for research and practice are discussed. Supplementary Information: The online version contains supplementary material available at 10.1007/s10882-022-09853-w.

RESUMO

Soursop possesses the largest fruit size of the Annona genus. However, this species is threatened by the Annonaceae fruit weevil (Optatus palmaris), which can cause the destruction of whole soursop fruits. Recently, the potential of semiochemicals for the management of this insect is highlighted, and its aggregation pheromone has been elucidated. This pheromone works well only when mixed with soursop volatiles. Thus, the aim of this research was to determine specific kairomone components to potentiate the aggregation pheromone of this Annonaceae fruit weevil. This task was carried out via volatilome analysis of soursop fruits, which was correlated with the biological activity of the identified volatiles. The GC-MS analysis of aroma collections of mature soursop fruits and flowers, determined using multivariate data analysis, confirmed a volatile differentiation between these organs. The volatile variation between fruits and flowers was reflected in weevils' preference for mature fruits instead of flowers. Moreover, weevils' response to soursop fruits increased with more mature fruits. This was correlated with volatile changes throughout the phenological stages of soursop fruits. The two volatiles most correlated with weevils' attraction were benzothiazole and (E)-ß-caryophyllene. These volatiles only evoked a response when mixed and potentiated the attraction of the aggregation pheromone. Thus, these two volatiles are active kairomone components with the potential for being used in combination with the aggregation pheromone of Annonaceae fruit weevils in field trials.

RESUMO

PURPOSE: Our objective is to analyze the variables that influence the outcome of Small Bowel Transplantation (SBT) in rats in an experimental microsurgery program. The surgical technique and perioperative care are described in detail. METHODS: Retrospective study of the SBT in rats conducted in our experimental surgery laboratory from 2002 to 2010. The animals were divided into group A (those who survived more than 48 hours) and group B (those who died earlier without justificable cause). We compared in both groups: number of transplants performed by the surgeon, warm ischemia time, cold ischemia time and duration of the procedure. RESULTS: Five surgeons with different degrees of microsurgical training participated in the study. A total of 521 SBT were performed with an overall survival of 48%. The first successful transplant was performed after a median of 46 (25-68) transplants. Total procedure time (3.5 vs 2.9 hours) and warm ischemia time (51 vs 35 minutes) were higher in group B (p < 0.05). DISCUSSION: The number of transplants required for learning the technique is high. However, survival is acceptable when the time needed for vascular anastomosis is reduced. The SBT in rats is a valuable model for surgical training and research of the phenomena related to SBT.

RESUMO

Ambient air quality, pollution and its implication on health is a topic of enormous importance that is normally dealt with by major specialists in their particular areas of interest. In general, it is not discussed from multidisciplinary approaches or with a language that can reach everyone. For this reason, the Health Sciences Foundation, from its prevention area, has formulated a series of questions to people with very varied competences in the area of ambient air quality in order to obtain a global panorama of the problem and its elements of measurement and control. The answers have been produced by specialists in each subject and have been subjected to a general discussion that has allowed conclusions to be reached on each point. The subject was divided into three main blocks: external ambient air, internal ambient air, mainly in the workplace, and hospital ambient air and the consequences of its poor control. Along with the definitions of each area and the indicators of good and bad quality, some necessary solutions have been pointed out. We have tried to know the current legislation on this problem and the competences of the different administrations on it. Despite its enormous importance, ambient air quality and health is not usually a topic of frequent presence in the general media and we have asked about the causes of this. Finally, the paper addresses a series of reflections from the perspective of ethics and very particularly in the light of the events that the present pandemic raises. This work aims to provide objective data and opinions that will enable non-specialists in the field to gain a better understanding of this worrying reality.

RESUMO

According to International Society for the Study of Vascular Anomalies classification, vascular anomalies are mainly divided into two groups: vascular tumors and vascular malformations. Nevertheless, a small group of patients present clinical and/or histopathologic overlapping features. We report a case of a 4-month-old boy that presented a vascular lesion on his right buttock with involvement of abdominal wall muscles, abdominal cavity and drainage to primitive iliac by a tortuous drainage vein. Surgery was performed and histopathology demonstrated a combined vascular malformation. Six months later he developed a thrombocytopenia and repeat magnetic resonance imaging revealed a new solid mass involving the majority of the abdominal cavity. At 18 months of age the patient developed a Kasabach-Merrit phenomenon and treatment with vincristine, interferon and then acetyl-salicilic acid and dypiridamol was started. No response in platelet counts was obtained and one more surgery was perfomed. On this occasion a histopathologic study revealed vascular malformation areas intermingled with areas of kaposiform hemangioendothelioma. This patient demonstrates the Kasabach-Merritt phenomenon with kaposiform hemangioendothelioma arising within a pre-existing combined vascular malformation.

RESUMO

Surgery for chronic inflammatory bowel disease (IBD) is increasingly often necessary in children. This study aimed at assessing the results of these operations in order to facilitate adequate preoperative counseling. We reviewed patients treated from 1992 to 2009. The operations, complications and functional outcome were recorded. For those with preserved rectal defecation, continence (Koivusalo score) and quality of life (standardized questionnaire) were assessed in the long term. Eighty five of 192 patients had Crohn disease (CD), 107 of 192 had ulcerative colitis (UC), and 3 of 192 had indeterminate colitis (IC). 12 of 85 CD patients (15%) aged 14 (12-19) years required 13 resections, 1 stricturoplasty, 1 transplantation and 6 other operations including 3 permanent enterostomies for anorectal involvement. Removal of the involved bowel led to significant improvement of nutritional status, growth and quality of life. The transplanted patient had a striking recovery but eventually died 1 year later of unrelated complications. 29 of 107 UC patients (26%) aged 11 (2-15) years required 87 operations. Nine had emergency colectomy for toxic megacolon (3, one death) or severe hemorrhage (6). 28 had restorative proctocolectomy and ileoanostomy (RPCIA) without (16) or with (12) J-pouch under protective ileostomy. Complications were frequent (40%). Permanent ileostomy was required in five children (17%). Twelve months postoperatively, RPCIA patients had 6.5 (2-13) stools/day; all were continent during daytime, and 25% have nocturnal leaks. Mean Koivusalo score (5-12) was 8.8 ± 2. Quality of life was good in all. All attended normal school and 7 the university, 4 work and 60% of those older than 18 years have sexual partners. Three of 107 children treated as UC with RPCIA had ultimately IC (3%) and were permanently diverted. The nature of IBD involves frustrating surgery. However, it may change life for CD patients and provide a reasonably good quality of life for UC after the first year. Pediatric surgeons should be able to provide adequate preoperative counseling to patients and families.
