Introduction: Boerhaave syndrome is a spontaneous rupture of the esophageal wall caused by a sudden increase in intraesophageal pressure. It represents an incidence of approximately 15% of all esophageal perforations, which do not exceed 3.1 per 1 million inhabitants per year. Objectives: To communicate the clinical presentation and management of patients with this syndrome, as well as to reveal the different options available in our service for its treatment. Methods: Search in the statistical data of the regional Hospital of Talca for patients with a diagnosis of Boerhaave syndrome. Five patients were found. Information was obtained from their clinical records and is presented as a clinical case report with a descriptive analysis of their management. Results: Of the 5 clinical cases presented, a classic clinical presentation can be observed, most of the patients presented with vomiting that later evolved with thoracic and/or epigastric pain, associated with imaging studies suggesting esophageal perforation. Management was surgical in 100% of the cases, applying different techniques described in the literature. Discussion and Conclusion: Boerhaave syndrome is a medical-surgical emergency that requires timely management. In spite of the variety of management and the consequences of each one of them, all the patients had an evolution that allowed them to preserve their lives until nowadays. Keeping a high index of suspicion and choosing the best management will have an impact on morbidity and mortality.

SUMMARY OBJECTIVE: Neonates are more susceptible to drug interactions and adverse effects, and special care should be taken when prescribing medication to them. This study aimed to investigate drug usage in the neonatal intensive care unit of a tertiary care hospital. METHODS: This prospective observational study was conducted on 98 patients at the Apollo tertiary care hospital (Bannerghatta, Bangalore, India) in a period of 6 months. The most common indications for neonatal intensive care unit admission, average number of drugs per patient, the most frequently used medication, distribution of patients based on the birth procedure, and possible drug interactions were collected from patient profiles. RESULTS: Among the patients, 52% were males and 48% were females. Notably, 38% of patients were preterm, 60% were term, and only 2% were post-term. Also, 80.6% were born by cesarean section and 19.4% were born by normal vaginal delivery. The highest mean of drug use was in the patient of 1,000-1,500 g (8.06 per patient). Preterm was the most frequent indication for admission in neonatal intensive care unit, followed by hyperbilirubinemia and then respiratory distress syndrome. The most frequently used medication was vitamin K (99%) and antibiotics followed by dextrose. In different types of antibiotics, amikacin (41%), cefoperazone+sulbactam (35%), cephalosporin (1%), ceftriaxone (0.7%), and amoxicillin (0.3%) were commonly administered. There were some possible interactions, such as aminoglycoside with furosemide and calcium gluconate. CONCLUSION: Premature birth and resulting low birth weight were the main reasons for drug prescription. High administration of antibiotics is probably an area of concern and should be seriously considered.

Abstract High doses of antibiotics used in hospitals can affect the microbial composition of sewers, selecting resistant bacteria. In this sense, we evaluated the antibiotic resistance profile and the multiresistant phenotype of bacteria isolated in sewage from a tertiary hospital in the interior São Paulo state, Brazil. For bacteria isolation, 10 µL of sewage samples were sown in selective culture media and the isolates were identified using VITEK-2 automatized system. The antibiotic sensitivity test was performed by disk diffusion. High percentages of resistance were found for amoxicillin, ampicillin, ceftazidime, clindamycin, vancomycin and the multidrug-resistant phenotype (MDR) was attributed to 60.7% of the isolates. Our results show bacteria classified as critical/high priority by WHO List of Priority Pathogens (Enterococcus and Staphylococcus aureus resistant to vancomycin and Enterobacteriaceae resistant to carbapenems) in hospital sewage. Therefore, the implementation of disinfection technologies for hospital sewage would reduce the bacterial load in the sewage that will reach urban wastewater treatment plants, minimizing superficial water contamination and bacterial resistance spread in the environment.

Resumo Altas doses de antibióticos utilizados em hospitais podem afetar a composição microbiana dos esgotos, selecionando bactérias resistentes. Nesse sentido, avaliamos o perfil de resistência a antibióticos e o fenótipo multirresistente de bactérias isoladas em esgoto de um hospital terciário no interior do estado de São Paulo, Brasil. Para o isolamento de bactérias, foram semeados 10 µL das amostras de esgoto em meios de cultura seletivos e os isolados foram identificados usando o sistema automatizado VITEK-2. O teste de sensibilidade aos antibióticos foi realizado por disco-difusão em ágar. Elevadas porcentagens de resistência foram encontradas para amoxicilina, ampicilina, ceftazidima, clindamicina, vancomicina e o fenótipo multirresistente (MDR) foi atribuído a 60,7% dos isolados. Nossos resultados mostram bactérias classificadas como prioridade crítica/alta pela Lista de Patógenos Prioritários da OMS (Enterococcus e Staphylococcus aureus resistentes à vancomicina e Enterobacteriaceae resistentes aos carbapenêmicos) no esgoto hospitalar. Sendo assim, implementação de tecnologias de desinfecção do esgoto hospitalar reduziriam a carga bacteriana no esgoto que chegará às estações de tratamento de esgoto urbanas, minimizando a contaminação dos ecossistemas hídricos receptores e a disseminação da resistência bacteriana no ambiente.

Background. Bloodstream infections are an important cause of mortality in children. Blood cultures (BCs) remain the primary means of identifying organisms and their antibiotic susceptibility profiles. A shortcoming of BCs is that up to 56% of positive cultures will represent contaminants. Poor adherence to standard practices applicable to BC sampling could explain an unacceptable contamination rate. Objectives. To determine: (i) the BC contamination rate in the departments of paediatrics and child health at two tertiary hospitals in central South Africa; and (ii) BC sampling practices among paediatric clinicians. Methods. The author determined the prevalence of BC contamination by analysis of laboratory data for the period 1 May - 27 August 2019, and assessed possible factors contributing to BC contamination by surveying paediatric medical staff with a self-administered BC practices questionnaire. Results. Of the 244 BCs reviewed, 25.4% were positive. The most commonly isolated pathogens were coagulase-negative staphylococci (CoNS) (33.3%), Escherichia coli (22.2%), Enterococcus faecium (16.7%) and Acinetobacter baumannii (11.1%). In total, 15.2% of the BCs yielded contaminants and 2.9% had polymicrobial growth. The most common contaminant was CoNS. Approximately 68% of clinicians were not aware of BC sampling guidelines, and even among those who were aware of the guidelines, non-compliance was reported. Conclusions. The BC contamination rate was higher than internationally accepted rates. Educating clinicians on specific BC sampling guidelines is strongly recommended to decrease the high rate of contamination observed in this study.

Objective: Knowledge of provisions of the National Health Act among physicians and stakeholders is pivotal to its successful implementation. This study aimed to assess the knowledge of the National Health Act (NHA) among Physicians in two tertiary hospitals in Nigeria. Methods: This was a cross-sectional study conducted in two tertiary hospitals in Southern Nigeria. The consecutively recruited eligible respondents were assessed for knowledge of NHA using a 24-item self administered close-ended structured questionnaire. The total obtainable score was 26. Those with <13 points had poor knowledge, 13-21 points had good knowledge and >21 points had excellent knowledge. Data were analyzed using SPSS version 21 software. P-value of < 0.05 was taken as significant. Results: One hundred and ninety-five doctors with a male: female ratio of 1.9:1 participated in the study. The majority (91.8%) were ≤40 years and 129(66.2%) of the participants were ≤ 10 years post qualification. The frequency of correctly answered questions ranged between 7.7% - 89.2%. According to overall knowledge scores; 64.6% had poor knowledge; 35.4% had good knowledge and none had excellent scores. There was no statistically significant association between knowledge of NHA and gender, age, and number of years post qualification (p > 0.05). Conclusion: This study showed that only about a third of the participants had good knowledge of key provisions of the NHA. We strongly recommend that relevant sections of the Act should be incorporated into the medical curriculum both at the undergraduate and postgraduate levels.

Background: The elements of job satisfaction can be categorized into intrinsic and extrinsic factors. The presence of a higher level of intrinsic factors will result in increased motivation amongst employees, whilst extrinsic factors will result in job dissatisfaction. Decreased job satisfaction levels amongst healthcare professionals are known to create an intent to leave. Hence the need to explore these factors amongst radiographers employed by tertiary hospitals in the Gauteng province of South Africa. Objective: To determine the influence of intrinsic and extrinsic factors of job satisfaction on intent to leave amongst radiographers employed by public tertiary hospitals in the Gauteng province. Methods: A quantitative cross-sectional survey guided the study, and a self-administered questionnaire was used to collect data. The sampling technique used for this study was disproportional stratified sampling. Results: The study had a response rate of 62%. A significant number of the participants (50%) were between the ages of 21-33 years. Also, worth noting that 51% of the participants were newly qualified, 28% were employed for a period of 10-20 years and only 20% were employed for a period greater than 20 years. Diagnostic radiography had the most number of participants at 55%, followed by radiation therapist at 24%, nuclear medicine radiographers at 13%, mammography radiographers at 5% and only 3% were sonographers. Pearson's correlation showed a significant negative correlation with the following extrinsic factors: supervision, r= -.344, p=.000; satisfaction with PMDS, r=-.302, p=.000; human resources processes, r=-.249, p=.001; infrastructure, r=-.236, p=.001; the OSD policy, r=-.233, p=.002; satisfaction with remuneration, r=-.202, p=.006; satisfaction with CPD activities, r=-.201, p=.007; and satisfaction with equipment, r=-.163, p=.029. Conclusion: Both intrinsic and extrinsic factors are associated with an intent to leave amongst radiographers employed by public tertiary hospitals in the Gauteng province

BACKGROUND: PCO occurs commonly postoperatively followingcataract extraction in children, obscuring vision as did the initialcataract. It may require a second surgical procedure when it is dense.It is expected that this results in restoration of vision and it is importantto ascertain that this is the case as well as to examine any significantchanges in refraction thereafter.M ETHODS: A retrospective observational study extractingdemographic and clinical information from case notes of patients whohad membranectomy and/or capsule polishing between October 2017and September 2018.RESULTS: 57 eyes of 51 patients were enrolled. There was a 2:1male: female ratio. Mean age at cataract surgery was 6.33 3.59yearswhilst that for PCO surgery was 9.68 3.89years. Postoperativevisual acuity (by WHO definition) was good (between 6/6 and 6/18)in 33.3%, compared to 8.8% preoperatively. Whereas presenting visualacuity was poor (<6/60) in 61.4% preoperatively, this reduced to30% postoperatively. Visual outcome was influenced by age at cataractsurgery, age at PCO surgery, interval between cataract and PCO surgeryand type of cataract. Children >8 years of age at time of PCO surgeryhad a greater proportion of good post-operative best corrected visualacuity (BCVA) (52.6%), whilst 75% of children younger than 8yearsat time of surgery turned out with poor BCVA after surgery.Developmental cataracts proportionately had the best outcome ofvisual acuity. There was a range of refractive shift of +0.25D to ­5.25D with a mean myopic shift of ­1.51D following membranectomy. CONCLUSION: There was a good proportion of children withsignificant improvement in visual acuity on the short term,and a mildmyopic shift following membranectomy.

INTRODUCTION: The burden of HIV is on the rise and patientswith HIV are also vulnerable to renal impairment from bothacute and chronic causes. This study sets out to evaluate renalcare received by such patients.METHODS: The study was conducted at Connaught Hospital,the main tertiary hospital (for medical and surgical cases) in thecountry. A retrospective review of all admitted patients withHIV between January and December 2019. Data was collectedusing a well- structured study proforma. RESULTS: A total of 230 patients were admitted with HIV duringthe study period. The mean age of patients was 36.9 ± (11.5) years with a female preponderance of 61.3%. A vast majority ofthe patients (54.8%) could afford to do some renal investigationsand only 13.9% were seen by renal physicians; 69.1% of patientswith azotaemia died while on admission.CONCLUSION: The extent of renal care observed from thestudy was poor because the majority of the patients were notseen b y r e na l physic ia ns a nd co uld no t affor d r e na linvestigations. Also, the occurrence of renal impairment inpatients with HIV suggests a poor prognosis. WAJM 2022;39(11): 1193­1197.

Resultados Realizaram retinografia 727 pacientes diabéticos, que tinham entre 14 e 91 anos, sendo a maioria com 60 anos ou mais (53,2%), do sexo feminino (68%) e brancos (87,6%). Não apresentavam retinopatia diabética 467 (64,2%) pacientes, 125 (17,2%) tinham retinopatia diabética não proliferativa, 37 (5,1%) retinopatia diabética não proliferativa grave e/ou suspeita de edema macular, 65 (8,9%) retinopatia diabética proliferativa, 21 (2,9%) suspeita de outras patologias, e as imagens de 12 (1,7%) pacientes eram insatisfatórias. Foram considerados de alto risco (aqueles com retinopatia diabética não proliferativa grave e/ou edema macular, retinopatia diabética proliferativa ou imagem insatisfatória) 114 (15,68%) pacientes. Conclusão O rastreio de retinopatia diabética com retinografia colorida possibilitou a detecção de pacientes diabéticos de alto risco que necessitavam atendimento com brevidade, permitindo o acesso deles à consulta oftalmológica e diminuindo a morbidade da doença relacionada ao tratamento tardio. Os demais foram encaminhados à Atenção Primária para regulamentação, por meio do Sistema de Regulação.

ABSTRACT Objective To evaluate the impact of diabetic retinopathy (DR) screening using color retinography in diabetic patients. Methods Retrospective descriptive study, evaluating reports of all retinographs performed since the implementation of the protocol for screening for diabetic retinopathy in diabetic patients followed up at the endocrinology outpatient clinic of a tertiary hospital of the Unified Health System, from May 2018 to May 2020. Results 727 diabetic with age range from 14 to 91 years old, the majority being 60 years old or older (53.2%), female (68%) and white (87.6%), patients underwent retinography. Of the patients, 467 (64.2%) did not have DR, 125 (17.2%) had non-proliferative DR, 37 (5.1%) had severe non-proliferative DR and/or suspected macular edema, 65 (8.9%) had proliferative DR, 21 (2.9%) had suspicion signs of other pathologies and 12 (1.7%) had unsatisfactory images. A total of 114 (15.68%) patients were considered at high risk (those with severe non-proliferative NP and/or EM, proliferative DR or poor image) and were referred for comprehensive ophthalmic evaluation. Conclusion The screening of RD with color retinography enabled the detection of high-risk diabetic patients who needed assistance sooner and enabled their access to ophthalmologic consultation, which decreased disease morbidity. The others were referred to primary care for regulation through the Regulation System (SISREG).

We aimed to evaluate ten-year outcomes of penile prosthesis (PP) implantation for the treatment of erectile dysfunction and to assess predictors of early prosthetic infection (EPI). We identified 549 men who underwent 576 PP placements between 2008 and 2018. Univariate and multivariate analyses were used to identify potential predictors of EPI. An EPI predictive nomogram was developed. Thirty-five (6.1%) cases of EPI were recorded with an explant rate of 3.1%. In terms of satisfaction, 82.0% of the patients defined themselves as "satisfied," while partner's satisfaction was 88.3%. Diabetes (P = 0.012), longer operative time (P = 0.032), and reinterventions (P = 0.048) were associated with EPI risk, while postoperative ciprofloxacin was inversely associated with EPI (P = 0.014). Rifampin/gentamicin-coated 3-piece inflatable PP (r/g-c 3IPP) showed a higher EPI risk (P = 0.019). Multivariate analyses showed a two-fold higher risk of EPI in diabetic patients, redo surgeries, or when a r/g-c 3IPP was used (all P < 0.03). We showed that diabetes, longer operative time, and secondary surgeries were the risk factors for EPI. Postoperative ciprofloxacin was associated with a reduced risk of EPI, while r/g-c 3IPP had higher EPI rates without an increased risk of PP explant. After further validation, the proposed nomogram could be a useful tool for the preoperative counseling of PP implantation.

INTRODUCTION@#Proton pump inhibitors (PPIs) are effective treatments for upper gastrointestinal pathologies and short-term courses are well-tolerated. However, indiscriminate use of PPIs is undesirable due to its potential harms. We implemented a series of deprescribing interventions between 2016 and 2017 to curb PPI overutilisation in our institution. The aim of this study was to evaluate the effectiveness and safety of these interventions.@*METHODS@#An institutional PPI deprescribing guide was disseminated by email and educational roadshows were conducted to prescribers. Interrupted time series analysis was used to evaluate the effectiveness of the deprescribing interventions over a 7-year period from 2013 to 2019. To ascertain the safety of PPI deprescribing, we analysed the peptic ulcer disease incidence from 2015 to 2018 and conducted a retrospective chart review of 262 inpatients who were deprescribed PPIs.@*RESULTS@#Following the first intervention, there was a significant decrease in mean oral PPI utilisation by 2,324.46 defined daily doses (DDD) per 1,000 prescriptions (95% confidence interval [CI] -3,542.66, -1,106.26) per month, followed by a month-to-month decrease of 302.61 DDD per 1,000 prescriptions per month thereafter (95% CI -473.95, -131.27). A second targeted educational intervention was only effective in sustaining the decline in the outpatient, but not in the inpatient setting. There were no significant changes in incidence of peptic ulcer disease. In the retrospective chart review, a majority (62.6%) of patients remained deprescribed at 6 months.@*CONCLUSION@#We observed a sustained decrease in PPI utilisation in our institution for more than 12 months following our educational interventions. Cautious deprescribing of PPIs in eligible candidates was found to be safe with low recurrence rates of upper gastrointestinal events.

OBJECTIVE@#To analyze the effects of ozone (O3) concentrations measured with different approaches across different seasons on the total number of childhood asthma-related clinical visits, as well as the differentiation of such effects across different groups of patients.@*METHODS@#The outpatient data of three grade A tertiary hospitals in Lanzhou City spanning from 1 January 2014 to 31 December 2017, as well as air pollution and meteorological data during the same period were collected. Considering the nonlinear relationship between O3 concentrations and the total number of childhood asthma-related clinical visits and meteorological factors, a generalized additive temporal sequence model was employed to analyze the short-term association between changes in O3 concentrations and the total number of childhood asthma-related clinical visits. Taking into account of the variations in O3 concentrations within 1 day, this study adopted different measurement approaches to address the three types of O3 exposures, namely, the maximum 1 h daily concentration (O3max1h), the maximum 8 h daily concentration (O38h) and the mean 24 h daily concentration (O324h) as the short term exposure indicators to O3, followed by a model-based analysis.@*RESULTS@#The increase in short-term exposure levels to O3 in summer had a significant effect on the increase in the total number of childhood asthma-related clinical visits. With lag0 for the current day, every 10 μg/m3 increase in atmospheric concentration of O3max1h was associated with an increase in the total number of childhood asthma-related clinical visits by 3.351% (95%CI: 1.231%-5.516%); for every 10 μg/m3 increase in O38h concentration, the total number of childhood asthma-related clinical visits increased by 3.320% (95%CI: 0.197%-3.829%); for every 10 μg/m3increase in O324h concentration, the total number of childhood asthma-related clinical visits in summer increased by 6.600% (95%CI: 0.914%-12.607%); moreover, an increase in exposure to O3max1h also led to a significant rise in the total number of childhood asthma-related clinical visits among the males.@*CONCLUSION@#The increase in short-term exposure levels to O3 in summer in Lanzhou City has a significant effect on the increase in the total number of childhood asthma-related clinical visits; O3max1h is more closely correlated with the increase in the total number of childhood asthma-related clinical visits.

ABSTRACT Background Inpatient consultations are a fundamental component of practice in tertiary care centers. However, such consultations demand resources, generating a significant workload. Objectives To investigate the profile of inpatient consultations requested by other specialties and provided by the Vascular and Endovascular Surgery team at an academic tertiary hospital. Methods Prospective observational study. Results From May 2017 to May 2018, 223 consultations were provided, representing 2.2% of the workload. Most consultations were requested by Oncology (16.6%), Hematology (9.9%), Nephrology (9.0%), and Cardiology (6.3%). The leading reasons for inpatient consultation were: need for vascular access (51.1%) and requests to evaluate a vascular disease (48.9%). Acute venous diseases accounted for 19.3% of consultations, chronic arterial diseases for 14.8%, acute arterial diseases for 7.2%, diabetic feet for 5.4%, and chronic venous diseases accounted for 2.2%. Surgical treatment was performed in 57.0%, either conventional (43.9%) or endovascular (13.0%). Almost all (98.2%) patients' issues were resolved. Conclusions Inpatient consultations with the Vascular and Endovascular Surgery team in a tertiary academic hospital accounted for 2.2% of the team's entire workload. Most patients were elective and underwent low-complexity elective surgical procedures. There may be an opportunity to improve healthcare, redirecting these patients to the outpatient flow.

RESUMO Introdução Interconsultas são um componente fundamental da prática clínica em centros de atendimento terciários. No entanto, esse tipo de consulta requer recursos, resultando em uma alta carga de trabalho. Objetivo Investigar o perfil das interconsultas solicitadas por outros departamentos e realizadas pela equipe de Cirurgia Vascular e Endovascular em um hospital universitário terciário. Métodos Estudo observacional prospectivo. Resultados De maio de 2017 a maio de 2018, foram realizadas 223 consultas, correspondendo a 2,2% da carga de trabalho. A maioria das consultas foram solicitadas pelos departamentos de Oncologia (16,6%), Hematologia (9,9%), Nefrologia (9,0%) e Cardiologia (6,3%). As principais razões das interconsultas foram a necessidade de acesso vascular (51,1%) e de avaliação de doenças vasculares (48,9%). As doenças venosas agudas corresponderam a 19,3% das avaliações; as doenças arteriais crônicas, a 14,8%; as doenças arteriais agudas, a 7,2%; o pé diabético, a 5,4%; e as doenças venosas crônicas corresponderam a 2,2%. Foi realizado tratamento cirúrgico em 57,0% dos casos, tanto convencional (43,9%) quanto endovascular (13,0%). Foram resolvidos os problemas de quase todos os pacientes (98,2%). Conclusão As interconsultas realizadas pela equipe de Cirurgia Vascular e Endovascular em um hospital universitário terciário corresponderam a 2,2% da carga de trabalho total. A maioria dos pacientes eram eletivos e foram submetidos a procedimentos cirúrgicos eletivos de baixa complexidade. O redirecionamento desses pacientes para o atendimento ambulatorial poderia auxiliar na melhoria dos serviços de saúde.

Resumo Fundamento A pandemia da COVID-19 representa uma enorme carga para o sistema de saúde do mundo. Apesar de pacientes pediátricos terem sido relativamente poupados em comparação a adultos, estudos recentes mostraram um número crescente de pacientes críticos com Síndrome Inflamatória Multisistêmica Pediátrica (SIM-P) com disfunção cardiovascular importante. No entanto, pouco se conhece a respeito da relação entre anormalidades cardíacas e biomarcadores inflamatórios e de coagulação. Objetivos Investigar anormalidades ecocardiográficas em pacientes pediátricos com COVID-19 admitidos em um hospital terciário. Métodos Este foi um estudo longitudinal retrospectivo, baseado na revisão de prontuários médicos e ecocardiogramas de pacientes (0-19 anos) admitidos em um hospital terciário entre 30 de março e 30 de junho de 2020. Para a análise estatística, o nível de significância foi estabelecido em 5% (p<0,05). Resultados Foram incluídos 48 pacientes, 73% com doenças pré-existentes, 20 (41,7%) com SIM-P. A idade mediana foi 7,5 (0-18,6) anos; 27 (56,2%) eram do sexo masculino. A duração mediana de internação foi 15,4 (2-92) dias e sete (14,6%) pacientes morreram. Um total de 70 ecocardiografias foram realizadas, 66,7% submeteram-se ao exame somente uma vez, e 33,3% várias vezes. Vinte e três (48%) pacientes apresentaram anormalidades no ecocardiograma: oito (16.6%) disfunção sistólica do ventrículo esquerdo, seis (12.5%) disfunção sistólica do ventrículo direito, e 12 (25%) dilatação da artéria coronária (Z-score>+2,5). Anormalidades ecocardiográficas foram significativamente associadas com SIM-P, admissão na unidade de terapia intensiva pediátrica, suporte ventilatório/vasoativo, e morte ( p <0,05). Níveis significativamente mais altos de d-dímero (ng/mL) foram detectados em pacientes com disfunção ventricular esquerda [16733(4157-115668) vs. 2406.5(190-95040)], disfunção ventricular direita [25769(3422-115668) vs. 2803.5(190-95040)] e dilatação da artéria coronária [9652.5(921-115668) vs. 2724(190- 95040)] (p<0,05). Conclusão Anormalidades ecocardiográficas eram frequentes nos pacientes pediátricos com COVID-19 e associadas com piores desfechos clínicos. Exacerbação das vias de inflamação e coagulação pode exercer um importante papel na lesão cardiovascular nesses pacientes.

Abstract Background COVID-19 pandemic represents a huge burden to the health system in the world. Although pediatric COVID-19 patients have been relatively spared compared with adults, recent reports showed an increasing number of critically ill patients with multisystemic inflammatory syndrome in children (MIS-c), with marked cardiovascular impairment. Nevertheless, little is known about the relationship between cardiac abnormalities and inflammatory and coagulation biomarkers. Objectives to investigate echocardiographic abnormalities in pediatric patients with COVID-19 admitted to tertiary hospital. Methods this was a retrospective longitudinal study, based on the review of medical records and echocardiograms of patients (0-19 years) admitted to a tertiary hospital between March 30 and June 30, 2020. For statistical analysis, the significance level was set at 5% (p < 0.05). Results Forty-eight patients were enrolled, 73% with preexisting diseases, 20 (41.7%) with MIS-c. Median age was 7.5 (0-18.6) years; 27 (56.2%) were male. Median duration of hospitalization was 15.4 (2-92) days and seven (14.6%) patients died. A total of 70 echocardiograms were performed; 66.7% patients were scanned only once and 33.3% multiple times. Twenty-three (48%) patients showed echocardiographic abnormalities: eight (16.6%) left ventricle (LV) systolic dysfunction, six (12.5%) right ventricle (RV) systolic dysfunction and 12 (25%) coronary dilatation (Z-score>+2.5). Echocardiographic abnormalities were significantly associated with MIS-c, admission to the pediatric intensive care unit, multiple organ dysfunction, ventilatory/vasoactive support, and death (p<0.05). Significantly higher d-dimer (ng/mL) levels were detected in patients with LV dysfunction [16733(4157-115668) vs. 2406.5(190-95040)], RV dysfunction [25769(3422-115668) vs. 2803.5(190-95040)] and coronary artery dilation [9652.5(921-115668) vs. 2724(190- 95040)] (p<0.05). Conclusion Echocardiographic abnormalities in COVID-19 pediatric patients were frequent and associated with worse clinical outcomes. Exacerbation of the inflammation and coagulation pathways may play an important role in cardiovascular injury in those patients.

ABSTRACT BACKGROUND: The gold standard test for colorectal cancer screening the colonoscopy. Although this is the test of choice, colonoscopy misses a significant number of lesions, mainly in the proximal colon. With the purpose of reducing the number of lesions missed, new techniques have been studied, amongst them, retroflexed view in the right side of the colon and the second direct forward view. OBJECTIVE: Assessing the safety of the retroview in the proximal colon (cecum and ascending colon), its impact on the detection of lesions in the proximal colon and its advantage over the double right forward view using adenoma detection rate and adenoma miss rate. METHODS: Three hundred and ninety-three patients who came to Hospital Mater Dei to undergo colonoscopy from March to July 2017, prospectively. Out of these, 372 were included in the study based on the following exclusion criteria: being under 18 years of age, inadequate bowel preparations (Boston scale <7), history of colectomy, inflammatory bowel disease or polypoid diseases. First, an endoscopist inserted the colonoscope into the cecum and examine the cecum and the ascending colon with a forward view twice. In the third insertion into the cecum, retroflexed view was performed, cecal mucosa was examined until the hepatic flexure in search of polyps missed on forward view. All lesions found were resected and sent for histological analysis. RESULTS: In 334 (89.8%) patients, retroflexed view was performed successfully, 65.8% of failures were attributed to the loops of the device which prevented the maneuver. The direct view identified 175 polyps in the proximal colon in 102 people. Retroflexed view detected 26 polyps missed by the direct view in 24 (6.5%) people, with a missing rate of 12.9% in the test with only the forward view. Out of the 26 polyps found in retroview, 21 (80.76%) were adenomas, one of them with a high-grade dysplasia. Eleven patients had polyps seen only in retroflexed view. Retroview has increased the polyp detection rate from 27.41% to 31.72% and the adenoma detection rate from 21.77% to 25%. The adenoma miss rate by the double direct view was 12.8%. Without the retroview, one polyp in every 13.91 colonoscopies would be missed (number needed to treat - NNT=13.91). There was no adverse event. CONCLUSION: The retroflexed view technique in the proximal colon was shown to be safe, fast and feasible in most cases. It increased the adenoma detection rate and was shown to be advantageous in this study wit benefit beyond the double direct view.

RESUMO CONTEXTO: O exame padrão ouro para rastreamento de câncer colorretal é a colonoscopia. Apesar de ser o exame de escolha, a colonoscopia perde um número não desprezível de lesões, principalmente no cólon proximal. Com a intenção de reduzir a perda de lesões, novas técnicas são estudadas, dentre elas, a retroflexão em cólon direito e a segunda visão frontal direta. OBJETIVO: Avaliar a segurança da retrovisão no cólon proximal (ceco e cólon ascendente), o seu impacto na detecção de lesões em cólon proximal e sua superioridade sobre a dupla visão frontal direta usando taxa de detecção de adenoma e taxa de adenoma perdido. MÉTODOS: Foram avaliados 393 pacientes de forma prospectiva que procuraram o Hospital Mater Dei para realizar colonoscopia entre março e julho de 2017. Desses, 372 foram incluídos baseados nos critérios de exclusão: menores de 18 anos, preparos intestinais inadequados (escala de Boston <7), com antecedente de colectomia, doença inflamatória intestinal ou síndromes polipoides. Primeiramente um endoscopista realizou a inserção do colonoscópio até o ceco e examinou o ceco e o cólon ascendente em visão frontal por duas vezes. Na terceira reinserção até o ceco era realizada a retroflexão e inspeção da mucosa do ceco até a flexura hepática em busca de pólipos perdidos à visão frontal. Todas lesões encontradas foram ressecadas e enviadas para análise histológica. RESULTADOS: Em 334 (89,8%) pacientes a retroflexão foi realizada com sucesso, 65,8% dos insucessos foram atribuídos a alças no aparelho que impediram a manobra. A visão direta identificou 175 pólipos no cólon proximal em 102 pessoas. A retroflexão detectou 26 pólipos perdidos pela visão direta em 24 (6,5%) pessoas, com uma taxa de perda de 12,9% no exame apenas em visão frontal. Dos 26 pólipos encontrados em retrovisão, 21 (80,76%) eram adenomas, um deles com displasia de alto grau. Onze pacientes tinham pólipos vistos apenas em retroflexão. A realização da retrovisão aumentou a taxa de detecção de pólipo de 27,41% para 31,72% e a taxa de detecção e adenomas de 21,77% para 25%. A taxa de adenoma perdido pela dupla visão direta foi de 12,8%. Se a retrovisão não fosse realizada, um pólipo a cada 13,91 colonoscopias seria perdido (NNT=13,91). Não houve nenhum evento adverso. CONCLUSÃO: A técnica de retroflexão em cólon proximal mostrou-se segura, rápida e factível na maioria dos casos. Ela aumentou a taxa de detecção de adenomas e mostrou-se soberana neste estudo com benfeitorias além da dupla visão direta.
