RESUMO
OBJECTIVES: Pediatric autoimmune pancreatitis (P-AIP) is an uncommon disease whose diagnosis requires strong clinical suspicion. Late diagnosis increases morbidity. We aimed to compare the usefulness of the 2011 International Consensus Diagnostic Criteria (ICDC) for Autoimmune Pancreatitis with the 2018 INSPPIRE (INternational Study Group of Pediatric Pancreatitis: In search for a cuRE) criteria. METHODS: We retrospectively analyzed demographics and clinical, laboratory, radiological, and histological findings at diagnosis and during long-term follow-up in children diagnosed with AIP in 2 tertiary hospitals between 2008 and 2021. RESULTS: We included 11 patients [6 girls; median age at diagnosis, 12.5 (range 2.8-15.7) years]. The most common symptom was abdominal pain. Pancreatic enzymes were elevated in 10 patients, and serum immunoglobulin G4 was elevated in 1. Magnetic resonance imaging showed enlargement of the pancreatic head in 10 patients and general pancreatic enlargement in 1. Pancreatic and papilla tissue were obtained from 9 patients. All patients received corticosteroids (prednisolone), and 4 also received azathioprine. According to the ICDC, all patients were classified as probable or non-otherwise specified AIP. According to INSPPIRE criteria, all patients were classified as AIP. Using the INSPPIRE criteria would have avoided biopsies in 6 patients who responded well to corticosteroids. CONCLUSIONS: The INSPPIRE criteria are useful. Using the ICDC in pediatric patients can delay diagnosis and result in unnecessary invasive tests.

Vaccination with the 13-valent conjugated pneumococcal disease (PCV13) has reduced invasive pneumococcal disease (IPD), but there have been reports of vaccine failures. We performed a prospective study in children aged 2-59 months who received diagnoses of IPD during January 2012-June 2016 in 3 pediatric hospitals in Catalonia, Spain, a region with a PCV13 vaccination coverage of 63%. We analyzed patients who had been age-appropriately vaccinated but who developed IPD caused by PCV13 serotypes. We detected 24 vaccine failure cases. The serotypes involved were 3 (16 cases); 19A (5 cases); and 1, 6B, and 14 (1 case each). Cases were associated with children without underlying conditions, with complicated pneumonia (OR 6.65, 95% CI 1.91-23.21), and with diagnosis by PCR (OR 5.18, 95% CI 1.84-14.59). Vaccination coverage should be increased to reduce the circulation of vaccine serotypes. Continuous surveillance of cases of IPD using both culture and PCR to characterize vaccine failures is necessary.

Supraventricular tachycardias (SVT) are the most common arrhythmias in the perinatal period. Permanent junctional reciprocating tachycardia (PJRT) is a rare form of SVT, often incessant and refractory to pharmacological treatments. Our goal was to analyze the clinical features and treatment of PJRT in patients younger than 2 months and to describe their long-term outcomes. METHODS: Retrospective descriptive observational study of patients diagnosed between 2000 and 2015 in the NICU of a referral center for the treatment of pediatric arrhythmias. History of pregnancy, neonatal period, pharmacological treatment, electrophysiological study and long-term follow-up were reviewed. RESULTS: 129 of the 10.198 (1.26%) patients admitted to the NICU had SVT, sixteen of them (12.3%) being diagnosed as PJRT. Ten cases had a prenatal diagnosis. For those six patients postnatally diagnosed, the tachycardia was detected either during a routine check-up or because of acute hemodynamic instability. The majority of patients required combinations of drugs, despite that the tachycardia was poorly controlled. Fifteen patients underwent cardiac ablation, nine patients (60%) in the neonatal period and six during childhood. The procedure was completely effective in all cases. One patient had a transient complete AV block that resolved spontaneously 24 hours after the procedure. No other complications were seen. After a mean follow-up of 10.9 years, no patient has presented recurrence, cardiac dysfunction, signs of ischemia or EKG abnormalities, they all have a normal life. CONCLUSIONS: When PJRT is refractory to multiple drugs, cardiac ablation should be taken into account at early stages even in very young patients.

BACKGROUND: Central line-associated bloodstream infections (CLABSI) related to insertion and device care in intensive care units are frequent and preventable events. AIM: To evaluate the reduction in the rate of CLABSI through implementation of an insertion bundle. METHODS: A study was conducted in the Adult-ICU at the University Hospital of Neiva comparing a pre-interventional period with an interventional one, each lasting 6 months; the intervention consisting of implementing a bundle of measures for the insertion of central venous catheters (CVC). In the pre-intervention period (2010) the rate of CLABSI and the population's characteristics were evaluated. The bundle for the insertion of the CVC consisted in: hands hygiene, use of 2% clorhexidine, maximum sterile barriers and avoiding femoral access. RESULTS: The rate of CLABSI decreased from 5.56 to 3.26 per 1000 catheter days. The length of ICU stay and catheter duration were associated with a higher risk of infection associated to these devices (p < 0.05). Compliance with the bundle is a protective factor against the development of CLABSI (OR 0.45, p = 0.615). The staff adherence to the bundle was over 80%. CONCLUSION: Implementing a Central Line Insertion Bundle proved to be a useful measure in prevention of CLABSI in our hospital. This strategy could be implemented in other hospitals of similar complexity.

Introduction: Introduction: kinanthropometry is the current science that studies body parameters in relation to its functioning (such as body composition, proportionality, somatotype, etc.), with established norms, techniques and criteria. Objective: to relate anthropometric profile, attention and problem solving in higher education students in the field of physical activity in Chile. Method: quantitative-correlational approach, with non-experimental and cross-sectional design. Results: there is no significant relationship between body composition (body masses) and cognitive tests (attention and Raven). Regarding anthropometric data (body composition), no significant differences were observed between the sexes for any parameter. Conclusion: it can be deduced that the results of the cognitive factors may be associated with other variables, and not specifically with the variables that may affect anthropometric parameters. These are very interesting topics for future studies, so it is suggested to continue studying cognitive abilities with other variables.
Introducción: Introducción: la cineantropometría es la ciencia actual que estudia los parámetros corporales en relación con su funcionamiento (por ejemplo, composición corporal, proporcionalidad, somatotipo, etc.), con normas, técnicas y criterios establecidos. Objetivo: relacionar el perfil antropométrico, la atención y la resolución de problemas en estudiantes de educación superior en el ámbito de actividad física de Chile. Método: enfoque cuantitativo-correlacional, diseño no experimental y de corte transversal. Resultados: no existe una relación significativa entre la composición corporal (masas corporales) y las pruebas cognitivas (atención y Raven). En relación con los datos antropométricos (composición corporal), no se observaron diferencias significativas entre ambos sexos para ningún parámetro. Conclusión: se deduce que los resultados de los factores cognitivos pueden estar asociados a otras variables, y no específicamente a las variables que pueden afectar los parámetros antropométricos. Estos temas son muy interesantes para próximos estudios, por lo que se sugiere seguir estudiando las habilidades cognitivas con otras variables.

BACKGROUND: Invasive pneumococcal disease (IPD) is the most important bacterial infection in young children, and the introduction of pneumococcal conjugate vaccines has changed its presentation. This study compared the incidence, characteristics and serotype distribution of IPD before and after the introduction of the pneumococcal conjugate vaccine (PCV13). METHODS: Prospective enrolment of patients with IPD aged less than 60 months and admitted to either of 2 tertiary care hospitals between January 2007 and December 2009 (pre-PCV13 period) and January 2012 and June-2016 (PCV13 period). RESULTS: We identified 493 cases, 319 in the pre-PCV13 period and 174 in the PCV13 period. The incidence of IPD decreased from 89.7 to 34.4 casos per 100 000 habitantes ( -62%; P < .001). This decrease was observed in all forms of disease except necrotising pneumonia (increase from 0.8 to 3.7 casos/100 000 population). There was a significant reduction in all serotypes included in the PCV13 and not included in the PCV7. We did not find significant differences in length of stay, mortality or the frequency of sequelae between both periods, but in the PCV13 period, the length of stay in the paediatric intensive care unit and the duration of mechanical ventilation were longer (P = .00). The incidence of serotype 3 decreased from 10.4 to 6.9 casos per 100 000 population, although it was the serotype involved most frequently in patients with severe disease. CONCLUSIONS: After the introduction of the PCV13, there has been a significant decrease in IPD cases. Serotype 3 continues to be an important cause of severe IPD.

INTRODUCTION: Ductus arteriosus stenting is a palliative alternative for neonates with ductal-dependent pulmonary flow. OBJECTIVE: To present an alternative of arterial access for percutaneous coronary intervention in neonates. CLINICAL CASE: A term neonate with low weight diagnosed with pulmonary atresia with intact ventricular septum and severe hypoplasia of the tricuspid valve with dependent coronary circu lation. Due to the surgical risk and femoral artery damage and the anatomy of the ductus arteriosus, a left axillary arterial puncture was decided where a 3.5-millimeter coronary stent was successfully placed. The patient developed an axillary spasm that resolved spontaneously. CONCLUSION: Alternati ve arterial access other than the femoral artery route is an option for neonates with high surgical risk and low birth weight.

INTRODUCTION: Patients with invasive pneumococcal disease (IPD) may require admission into paediatric intensive care units (PICU). The aim of this study is to analyse the epidemiological, clinical, and microbiological characteristics associated with IPD that may require admission to the PICU. MATERIAL AND METHODS: A prospective study was conducted on cases of IPD diagnosed in three Paediatric Hospitals in Barcelona between January 2012 and June 2016. An analysis was made of the associations between the admission to PICU and the epidemiological, clinical, and microbiological variables. RESULTS: A total of 263 cases with IPD were included, of which 19% (n = 50) required admission to PICU. Patients with septic shock (7; 100%), meningitis (16; 84.2%), and those with complicated pneumonia (23; 15.2%) were admitted to the PICU. The most frequent complications were pulmonary (35.2%) and neurological (39.5%). The ratio between admission and non-admission to PICU was 4.7 times higher in subjects with an underlying disease. The serotypes associated with PICU admission were 19A (23% of the total of this serotype), serotype 14 (20%), serotype 3 (17%), and serotype 1 (12.5%). CONCLUSIONS: IPD required PICU admission in cases of septic shock and meningitis, and less so with complicated pneumonia. The percentage of admissions is greater in children with an underlying disease. Admission into the PICU involves a longer stay, complications during the acute phase, as well as sequelae, particularly neurological ones. The serotypes of the patients that were admitted to PICU were predominantly vaccine serotypes.

RESUMO
BACKGROUND: Some studies have observed an increased incidence of necrotizing pneumonia (NP) in recent years. This might be related to the emergence of non-vaccine S. pneumoniae serotypes after PCV7 introduction although it is suggested that evolutionary factors may have modified the virulence and the interactions of pneumococci. The aim of this study was to clinically and microbiologically define NP in the population served by the three major paediatric hospitals in Barcelona (Catalonia, Spain). METHODS: A prospective observational study was conducted in patients <18 years hospitalized due to invasive pneumococcal disease (January 2012-June 2016). Data of confirmed cases of pneumococcal NP (diagnosed by culture or DNA detection and serotyped) were collected. PCV13 was not systematically administered in Catalonia during the study period, but was available in the private market so the vaccination coverage in children increased from 48.2% to 74.5%. RESULTS: 35 cases of NP were identified. 77.1% of cases were associated with empyema. In the first 4 years, a trend to a decrease in NP incidence was observed (p=0.021), especially in children <5 years (p=0.006). Serotype 3 was responsible for 48.6% of NP cases. Five patients with NP due to serotype 3 were fully vaccinated for their age with PCV13. CONCLUSIONS: Serotype 3 has a preeminent role in pneumococcal NP and was associated with all PCV13 vaccination failures. Although in our series the incidence does not seem to be increasing, evolution of pneumococcal NP rates should be monitored after inclusion of PCV13 in the systematic calendar.

The lack of invasive pneumococcal disease (IPD) cost studies may underestimate the eect ofpneumococcal polysaccharide conjugated vaccines (PCV). The objective of this study was to estimatethe direct costs of hospitalized IPD cases. A prospective study was made in children aged <5 yearsdiagnosed with IPD in two high-tech hospitals in Catalonia (Spain) between 2007-2009 (PCV7 period)and 2012-2015 (PCV13 period). Costs were calculated according to 2014 Catalan Health Service ratesusing diagnostic-related groups. In total, 319 and 154 cases were collected, respectively. Pneumoniahad the highest cost (65.7% and 62.0%, respectively), followed by meningitis (25.8% and 26.1%,respectively). During 2007-2015, the costs associated with PCV7 serotypes (Pearson coecient (Pc) =?0.79; p = 0.036) and additional PCV13 serotypes (Pc = ?0.75; p = 0.05) decreased, but those of otherserotypes did not (Pc = 0.23 p = 0.62). The total mean cost of IPD increased in the PCV13 period by31.4% (¿3016.1 vs. ¿3963.9), mainly due to ICU stay (77.4%; ¿1051.4 vs. ¿1865.6). During the PCV13period, direct IPD costs decreased due to a reduction in the number of cases, but cases were more severe and had a higher mean cost. During 2015, IPD costs increased due to an increase in the costsassociated with non-PCV13 serotypes and serotype 3 and this requires further investigation.

RESUMO
OBJECTIVES: Methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections (SSTIs) represent a major clinical problem in Colombia. The aim of this study was to evaluate the risk factors associated with MRSA SSTI in Colombia. METHODS: A multicenter cohort study with nested case-control design was performed. Patients with an SSTI with at least 48h of inpatient care were included. Patients with an MRSA SSTI were considered the case group and patients with either a non-MRSA SSTI or with an Methicillin-susceptible S. aureus (MSSA) SSTI were the control groups. A multivariate logistic regression approach was used to evaluate risk factors associated with MRSA SSTI with two different statistical models. RESULTS: A total 1134 patients were included. Cultures were positive for 498 patients, of which 52% (n=259) were Staphylococcus aureus. MRSA was confirmed in 68.3% of the S. aureus cultures. In the first model, independent risk factors for MRSA SSTI were identified as the presence of abscess (P<0.0001), cellulitis (P=0.0007), age 18-44 years (P=0.001), and previous outpatient treatment in the previous index visit (P=0.003); surgical site infection was a protective factor (P=0.008). In the second model, the main risk factor found was previous outpatient treatment in the previous index visit (P=0.013). CONCLUSIONS: Community-acquired SSTIs in Colombia are commonly caused by MRSA. Therefore, clinicians should consider MRSA when designing the initial empirical treatment for purulent SSTI in Colombia, although there seems to be low awareness of this fact.

AIM: The aim was to analyze the epidemiological, microbiological and clinical characteristics of patients with complicated pneumococcal pneumonia with pleural effusion (PE) or empyema. METHOD: Prospective study in three Catalan hospitals in persons aged <18 years diagnosed with complicated pneumonia with PE or empyema with isolation of Streptococcus pneumoniae in blood or pleural fluid by culture or real-time PCR between January 2012 and June 2016. Patients were divided into <2 years and 2-17 years age groups. Epidemiological, microbiological, and clinical data of patients were compared annually in both groups. PCV13 vaccination coverage increased from 48.2% in 2012 to 74.5% in 2015. RESULTS: We included 143 patients. The incidence of pneumococcal pneumonia was 6.83 cases × 10-5 persons/year in cases with PE or empyema and 2.09 cases × 10-5 person-years in cases without (rate ratio [RR]: 3.27; 2.25-4.86; P < 0.001). Empyema was more frequent than PE (79.7% vs 20.3%, P < 0.005). Of 143 cases studied, 93 (65.0%, P < 0.001) were diagnosed by real-time-PCR, 43 (30.1%) by culture and RT-PCR and 7 (4.9%) by culture only. PCV13 serotypes were more frequent in complicated than in uncomplicated pneumonia (116/142, 81.7% vs 27/45, 60.0%; P = 0.003), especially serotype 1 (41/142, 28.9% vs 6/45, 13.3%, P : 0.036). From 2012 to 2015 there was a significant reduction in serotype 1 (16/43, 37.2% vs 3/27, 11.1%, P = 0.026), and a trend to an increase in non-PCV13 serotypes (6/43, 14% vs 9/27, 33.3%, P = 0.054). CONCLUSIONS: A directly proportional relationship was observed between the reduction in pneumonia complicated with PE or empyema and a significant reduction in PCV13 serotypes, especially serotype 1, coinciding with increased PCV13 coverage.

BACKGROUND: The rise of infections caused by multidrug-resistant Gram negative bacilli (MDR-GNB), added to paucity of newer therapy, have led to increase polymyxin B use, despite adverse renal toxicity profile. AIM: To determine the incidence and risk factors associated to acute kidney injury (AKI) and polymyxin B use, in patients with infections caused by MDR-GNB. METHODS: A retrospective cohort, with a nested case-control study of adults who received polymyxin B for more than 48 hours at a tertiary university hospital in Colombia (2011-2015) was performed. AKI was defined by AKIN criteria. RESULTS: Of 139 patients included in our study, 102 were male with median age of 49 years (IQR:28-64). Sixty-one patients (44%) developed AKI. Independent risk factors for development of AKI included: total polymyxin B daily dose (OR = 2.19, 95% CI, 1.04-4.64); length of stay at ICU (OR = 1.03, 95% CI, 1.00-1.06); nosocomial infection (OR = 6.43, 95% CI, 2.12, -19.47); and vasopressor use (OR = 5.38, 95% CI, 2.40-12.07). Mortality was higher among AKI-patients (58.6%) compared with non-AKI patients (25.6%) (p = 0.001). CONCLUSION: In this study, the rate of AKI associated to polymyxin B use was greater than reported in studies from last decade, and associated with increased mortality. AKI associated to polymyxin B use is likely multifactorial and aggravated by the critically ill state of patients suffering nosocomial infections caused by mdr-gnb.

BACKGROUND: The 13-valent pneumococcal conjugate vaccine (PCV13) was licensed based on the results of immunogenicity studies and correlates of protection derived from randomized clinical trials of the 7-valent conjugate pneumococcal vaccine. We assessed the vaccination effectiveness (VE) of the PCV13 in preventing invasive pneumococcal disease (IPD) in children aged 7-59 months in a population with suboptimal vaccination coverage of 55%. METHODS: The study was carried out in children with IPD admitted to three hospitals in Barcelona (Spain) and controls matched by hospital, age, sex, date of hospitalization and underlying disease. Information on the vaccination status was obtained from written medical records. Conditional logistic regression was made to estimate the adjusted VE and 95% confidence intervals (CI). RESULTS: 169 cases and 645 controls were included. The overall VE of ≥1 doses of PCV13 in preventing IPD due to vaccine serotypes was 75.8% (95% CI, 54.1-87.2) and 90% (95% CI, 63.9-97.2) when ≥2 doses before 12 months, two doses on or after 12 months or one dose on or after 24 months, were administered. The VE of ≥1 doses was 89% (95% CI, 42.7-97.9) against serotype 1 and 86.0% (95% CI, 51.2-99.7) against serotype 19A. Serotype 3 showed a non-statistically significant effectiveness (25.9%; 95% CI, -65.3 to 66.8). CONCLUSIONS: The effectiveness of ≥1 doses of PCV13 in preventing IPD caused by all PCV13 serotypes in children aged 7-59 months was good and, except for serotype 3, the effectiveness of ≥1 doses against the most frequent PCV13 serotypes causing IPD was high when considered individually.

We describe 2 patients with severe orbital myiasis due to Cochliomyia hominivorax (of the order Diptera and the family Calliphoridae) who had underlying skin carcinomas and were treated with oral ivermectin and debridement. We suggest that ivermectin plays an important role in the treatment of severe cases of myiasis.

OBJECTIVE: To review the existing literature on when and how to treat patients with asymptomatic bacteriuria (AB) who undergo urological surgery, as uncertainty about this issue persists. METHODS: A systematic review was conducted to compare the different timing of administration of antibiotic prophylaxis in patients with AB undergoing urological surgery. We used predefined inclusion and exclusion criteria, and we also developed a specific quality scale to assess the quality of the papers included. RESULTS: Nine studies met the inclusion criteria. Of the nine studies included, eight evaluated antibiotic prophylaxis regardless of the presence of AB, as their purpose was to evaluate the effectiveness of antibiotic prophylaxis for urological procedures. Of these, four studies showed a significant reduction in the rate of infections in the intervention group compared with placebo, or with the same antibiotic therapy but using different durations of therapy. Four studies found no significant differences in infectious complications between the intervention and comparison arms. Only one study assessed the duration of antibiotic prophylaxis in patients with AB. CONCLUSIONS: With the available evidence, antibiotic therapy should be considered only for procedures in which studies have shown a clinical benefit in the prevention of infection. It is important to establish the duration and type of treatment for antimicrobial therapy for surgical prophylaxis in patients with AB who are going to receive urological invasive procedures.
RESUMO
Tuberculous pyomyositis is a rare manifestation of extrapulmonary tuberculosis, most common in immunosuppressed patients, with clinical manifestations similar to pyomyositis of other etiologies, although with a lower age of presentation; notable risk factors include prior tuberculosis infection and pharmacological immunosuppression. Diagnosis depends on a high clinical suspicion of the infection in a susceptible population, given that microbiological isolation is often impossible. The response to treatment and prognosis are good. The case presented here is noteworthy given the rarity of this manifestation of tuberculosis and the slow response to first-line TB management in an HIV patient, despite susceptible microbiological isolation.
