Experience of the use of lock therapy in pediatric patients with central venous catheter. / Experiencia del uso de terapia de sello en pacientes pediátricos con catéter venoso central.

Lock therapy is useful for preserving indwelling catheters. Few lock therapy studies have been published in Latin America. OBJECTIVE: To describe the clinical characteristics of pediatric patients using therapeutic and prophylactic lock therapy for six years in a high-complexity hospital in Colombia. PATIENTS AND METHOD: Cross-sectional descriptive study of patients aged < 18 years who received lock therapy. Collected variables included demographic data, clinical characteristics, blood test results, therapeutic interventions, frequency of admission to the pediatric critical care unit, and mortality. Descriptive analysis was performed. RESULTS: 54 patients were included in the study, most of them males, with 67 episodes of therapeutic lock therapy use. The most frequent diagnosis was hematological neoplasm (61%). Among these patients, 88% presented neutropenia while receiving lock therapy. Catheter preservation was achieved in 75% of the cases. Aminoglycosides were the most commonly used antibiotics (38%). Mortality due to catheter-related bacteremia was 6%. Catheter preservation using ethanol solution 70% was achieved in 62% of the patients with prophylactic lock therapy, all of whom had chronic gastrointestinal pathology. CONCLUSION: Catheter preservation rates were 75% and 62% in patients with therapeutic and prophylactic lock therapy, respectively, with a higher rate achieved among cancer patients with neutropenia (80%). Aminoglycosides and vancomycin were the most commonly used antibiotics.

Review of Topical Sodium Heparin 1000 IU/g Gel in Symptomatic Uncomplicated Superficial Thrombophlebitis.

Heparin, a mixture of sulfated polymorphic polysaccharides (glycosaminoglycan) chains of variable lengths and weights and a natural anticoagulant, is widely used in medical practice to prevent intravascular blood coagulation. Heparin has demonstrated antithrombotic and anti-inflammatory activity, and it is mostly administered systemically (intravenously or subcutaneously) for primary or secondary prevention of venous thromboembolism after surgical interventions, or immobilized patients, or on short-term antithrombotic therapy of patients with atrial fibrillation who must undergo treatment. However, since systemic administration of heparin could be, in certain cases, linked to an increased risk of bleeding, topical heparin is widely used for the prevention and treatment of local symptoms of peripheral vascular disorders, such as venous insufficiency, varicose veins, or superficial thrombophlebitis. This review summarizes the main safety and efficacy characteristics of the topical formulation of Heparin in Gel form (1000 International Units of Heparin/g Gel) currently in use, which has demonstrated an excellent efficacy and tolerability profile in reducing signs and symptoms of peripheral vascular disease, e.g., varicose syndromes and their complications, phlebothrombosis, thrombophlebitis, superficial periphlebitis, varicose ulcers, for post-operative varicophlebitis, sequelae of saphenectomy, for traumas and contusions, local edemas and infiltrates, subcutaneous hematoma and for traumatic affections of musculotendinous and capsuloligamentous apparatuses.

Influence of age, education, and blast exposure on the Test of Memory Malingering in an active-duty military sample.

Neuropsychologists use performance validity tests (PVT) to detect performance invalidity across various populations. Unexpected scores for normative and clinical populations on PVT performance could invalidate the assessment if the poor performance does not have a reasonable explanation. One of the most well-validated and frequently used PVT is the Test of Memory Malingering, whose usefulness has been analyzed in various populations, including the military. Studies on the influence of demographic variables and blast exposure on the performance of military samples have yielded inconclusive results. The current study investigates the influence of age, education, and blast exposure on the TOMM Trial 2 in a military sample that is representative of their demographics. The total sample size was 872 participants between 18-62 years of age (M = 26.35, SD = 6.63), divided into 832 males and 40 females. All participants were on active duty, and they had been deployed in war zones in Afghanistan and Iraq. They were referred to Carolina Psychological Health Services from the Naval Hospital of Camp LeJeune for psychological and/or neurological complaints, such as cognitive difficulties. The results show that age, education, and blast exposure variations do not affect TOMM performance. Further studies on the relationship between these variables should be pursued to elucidate how they are associated with the normative or clinical cognitive functioning of military populations.

Recommendations for modernizing infant vaccination schedules with combination vaccines in Colombia and Peru.

The objective of this article was to consider the vaccination challenges in Colombia and Peru and the role of pediatric combination vaccines in overcoming these challenges. Barriers to including new vaccines with more antigens remain apparent in parts of these countries, where vaccine-preventable diseases in infants continue to be a major problem. The challenges include the heterogeneity of vaccine coverage within each country and in neighboring countries, which can contribute to poor rates of vaccination coverage; the adverse impact of the inward migration of unvaccinated individuals, which has favored the re-emergence of vaccine-preventable diseases; vaccine shortages; and the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and the associated shifts in health care resources. To improve the coverage of pediatric vaccines in Colombia and Peru, it will be necessary to ensure the widespread integration into vaccine schedules of combination vaccines containing diphtheria, tetanus, acellular pertussis, inactivated poliovirus, Haemophilus influenzae type b and hepatitis B antigens with a three-dose primary series delivered at 2, 4 and 6 months of age followed by a booster at 18 months of age. Such vaccines play important roles in preventing diphtheria, tetanus and pertussis; eradicating polio; and providing boosting against H. influenzae type b.

El objetivo de este artículo es considerar los desafíos que se enfrentan en Colombia y Perú con respecto a la vacunación y el papel de las vacunas combinadas pediátricas para superar estos desafíos. Los obstáculos para incluir vacunas nuevas con más antígenos siguen siendo evidentes en algunos lugares de estos países, donde las enfermedades prevenibles por vacunación en menores de 1 año continúan siendo un grave problema. Entre los desafíos se incluye la heterogeneidad de la cobertura de vacunación en cada país y en los países vecinos, lo que puede contribuir con que se registren tasas bajas de cobertura de vacunación; el impacto adverso de la migración interna de personas no vacunadas, lo que ha favorecido la reaparición de enfermedades prevenibles por vacunación; la escasez de vacunas, y el impacto de la pandemia del coronavirus de tipo 2 causante del síndrome respiratorio agudo grave (SARS-CoV-2) y los consiguientes cambios en los recursos de atención médica. Para mejorar la cobertura de las vacunas pediátricas en Colombia y Perú será necesario integrar de manera generalizada en los calendarios de vacunación vacunas combinadas con antígenos de difteria, tétanos, tos ferina acelular, poliovirus inactivados, Haemophilus influenzae tipo b y hepatitis B con una serie primaria de tres dosis administradas a los 2, 4 y 6 meses de edad, seguida de un refuerzo a los 18 meses de edad. Esas vacunas desempeñan un papel esencial en la prevención de la difteria, el tétanos y la tos ferina; la erradicación de la polio; y el refuerzo contra H. influenzae tipo b.

Etiology and the challenge of diagnostic testing of community-acquired pneumonia in children and adolescents.

BACKGROUND: Pneumonia is the leading cause of mortality in pediatric population. The etiology of pneumonia in this population is variable and changes according to age and disease severity and where the study is conducted. Our aim was to determine the etiology of community-acquired pneumonia (CAP) in children aged 1 month to 17 years admitted to 13 Colombian hospitals. METHODS: Prospective cohort study. Hospitalized children with radiologically confirmed CAP and ≤ 15 days of symptoms were included and followed together with a control group. Induced sputum (IS) was submitted for stains and cultures for pyogenic bacteria and Mycobacterium tuberculosis, and multiplex PCR (mPCR) for bacteria and viruses; urinary antigens for pneumococcus and Legionella pneumophila; nasopharyngeal swabs for viruses, and paired serology for atypical bacteria and viruses. Additional cultures were taken at the discretion of primary care pediatricians. RESULTS: Among 525 children with CAP, 71.6% had non-severe pneumonia; 24.8% severe and 3.6% very severe pneumonia, and no fatal cases. At least one microorganism was identified in 84% of children and 61% were of mixed etiology; 72% had at least one respiratory virus, 28% pyogenic bacteria and 21% atypical bacteria. Respiratory syncytial virus, Parainfluenza, Rhinovirus, Influenza, Mycoplasma pneumoniae, Adenovirus and Streptococcus pneumoniae were the most common etiologies of CAP. Respiratory syncytial virus was more frequent in children under 2 years and in severe pneumonia. Tuberculosis was diagnosed in 2.3% of children. IS was the most useful specimen to identify the etiology (33.6%), and blood cultures were positive in 3.6%. The concordance between all available diagnostic tests was low. A high percentage of healthy children were colonized by S. pneumoniae and Haemophilus influenzae, or were infected by Parainfluenza, Rhinovirus, Influenza and Adenovirus. CONCLUSIONS: Respiratory viruses are the most frequent etiology of CAP in children and adolescents, in particular in those under 5 years. This study shows the challenges in making an etiologic diagnosis of CAP in pediatric population because of the poor concordance between tests and the high percentage of multiple microorganisms in healthy children. IS is useful for CAP diagnosis in pediatric population.

Acute Intrathoracic Tuberculosis in Children and Adolescents with Community-Acquired Pneumonia in an Area with an Intermediate Disease Burden.

Tuberculosis (TB) in the pediatric population is a major challenge. Our objective was to describe the clinical and microbiological characteristics, radiological patterns, and treatment outcomes of children and adolescents (from 1 month to 17 years) with community-acquired pneumonia (CAP) caused by TB. We performed a prospective cohort study of a pediatric population between 1 month and 17 years of age and hospitalized in Medellín, Colombia, with the diagnosis of radiologically confirmed CAP that had ≤ 15 days of symptoms. The mycobacterial culture of induced sputum was used for the bacteriological confirmation; the history of TB contact, a tuberculin skin test, and clinical improvement with treatment were used to identify microbiologically negative TB cases. Among 499 children with CAP, TB was diagnosed in 12 (2.4%), of which 10 had less than 8 days of a cough, 10 had alveolar opacities, 9 were younger than 5 years old, and 2 had close contact with a TB patient. Among the TB cases, 50% (6) had microbiological confirmation, 8 had viral and/or bacterial confirmation, one patient had multidrug-resistant TB, and 10/12 had non-severe pneumonia. In countries with an intermediate TB burden, Mycobacterium tuberculosis should be included in the etiological differential diagnosis (as a cause or coinfection) of both pneumonia and severe CAP in the pediatric population.

Induced sputum as an adequate clinical specimen for the etiological diagnosis of community-acquired pneumonia (CAP) in children and adolescents.

OBJECTIVES: This study aimed to evaluate the utility of induced sputum (IS) for the diagnosis of community-acquired pneumonia (CAP) in pediatric population. METHODS: This cross-sectional study included pediatric population aged between 1 month and 17 years who were hospitalized with a diagnosis of CAP in 13 hospitals in Colombia, in whom an IS sample was obtained. Gram staining, aerobic bacterial and mycobacterial culture tests, and polymerase chain reaction (PCR) for 6 atypical bacteria and 15 respiratory viruses were performed. We evaluated the quality of IS samples. RESULTS: IS samples were collected in 516 of 525 children included in this study. The median age was 32 months, 38.6% were younger than 2 years, and 40.9% were between 2 and 5 years. Two patients had transient hypoxemia during the procedure. The quality of the IS obtained was good in 48.4% and intermediate in 24.5%. Identification of a respiratory pathogen was achieved with an IS sample (with Gram staining, culture test, and PCR) in 372 of 516 children with CAP. CONCLUSION: Our study shows that IS is an adequate sample for the diagnosis of CAP in pediatric population that required hospitalization. The procedure was safe, well tolerated, and with better diagnostic yields compared with the rest of the samples obtained.

Cáncer y acción preventiva en Chile: perfilando la abstención a la mamografía y papanicolaou / Abstention from pap smears and mammography among chilean women. Prevalence and causes

Background: Cancer is a public health problem among women, but preventive actions are effective. Aim: To outline the reasons and factors associated with abstention from pap smears and mammography examinations among women. Material and Methods: Using official databases of the WHO and the Ministry of Social Development of Chile, inferential statistical analyses and modeling of abstention through binomial logistic regression were carried out. Results: Breast and cervical cancer had the highest incidence and mortality among women over 35 years old in Chile, even when there are effective screening methods for their early detection. Abstention is conditioned by personal reasons such as low risk perception. There is a high concomitance of abstention for pap smears and mammography. Conclusions: Health promotion actions should encourage women to undergo preventive actions for breast and cervical cancer.

Relationship between expressions of aggression and individual characteristics in correctional settings: A path analysis.

BACKGROUND: The reduction of misconduct levels and its prevention are two important objectives in prison settings, for which several strategies and control mechanisms are implemented. OBJETIVE: We explore the relationship between a set of socio-demographic, judicial, affective, and personality characteristics and various expressions of aggression. METHOD: An Ecuadorian sample of 675 sentenced male prisoners was assessed using the Spanish adaptation of the Personality Assessment Inventory (PAI). Three subscales of the PAI were used as outcome measures: Aggressive Attitude (AGG-A), Verbal Aggression (AGG-V), and Physical Aggression (AGG-P). RESULTS: Using path analysis, three models were obtained, each of which had four indicators. Borderline personality features and antisocial personality features emerged as indicators that were common to the three models. Anxiety-related disorders and non-support were indicators specific to AGG-A, whilst schizophrenia and non-support were indicators of AGG-V, and drug problems and crimes against property were indicators of AGG-P. CONCLUSION: This study indicates that each expression of aggression has a different structure, which suggests its usefulness for detecting the tendency of an inmate to predominantly express one form of aggression or another.

Performance of SARS-CoV-2 rapid antigen test compared with real-time RT-PCR in asymptomatic individuals.

Screening, testing and contact tracing plays a pivotal role in control of the COVID-19 pandemic. To enable this it is necessary to increase the testing capacity. This study compared a SARS-CoV-2 rapid antigen test (RAT) and RT-PCR in 842 asymptomatic individuals from Tarapacá, Chile. A sensitivity of 69.86%, specificity of 99.61%, PPV of 94.44% and NPP of 97.22% with Ct values (Ct > 27) that were significantly higher among individuals with false-negative RAT were reported. These results support the fact that RAT might have a significant impact on the identification of asymptomatic carriers in areas that lack suitable laboratories to perform SARS-CoV-2 real-time RT-PCR diagnostics, or the results take more than 24-48 h, as well as zones with high traffic of individuals such as border/customs, airports, interregional bus, train stations or in any mass testing campaign requiring rapid results.

Case Report: Rhinosporidiosis Literature Review.

Rhinosporidiosis is caused by Rhinosporidium seeberi, a pathogen currently considered a fungus-like parasite of the eukaryotic group Mesomycetozoea. It is usually a benign condition, with slow growth of polypoid lesions, with involvement of the nose, nasopharynx, or eyes. The clinical characteristics of a painless, friable, polypoid mass, usually unilateral, can guide the diagnosis, but the gold standard for diagnosis is histopathological findings. This article reviews the epidemiology, pathobiology, clinical manifestations, diagnostic strategies, and treatment approach for rhinosporidiosis.

A Randomized Clinical Trial on the Use of Antiseptic Solutions for the Pin-Site Care of External Fixators: Chlorhexidine-Alcohol Versus Povidone-Iodine.

Pin-site infections remain a common clinical complication in patients with external fixators. Pin-site care is commonly performed with either chlorhexidine-alcohol solution or povidone-iodine solution. This study aimed to investigate the superiority of chlorhexidine-alcohol solution versus povidone-iodine solution for external fixator pin-site care in pin-site infection. This prospective randomized clinical trial using an open, parallel-group design was conducted in a single Spanish hospital. Eligible consenting patients from November 2018 to May 2019 who underwent placement of an external fixator were included. Patients were randomly assigned to receive pin-site care using either a 2% chlorhexidine-alcohol solution or a 10% povidone-iodine solution. The primary endpoint was the development of a pin-site infection. In total, 568 pins were analyzed (128 patients, with a mean of 4.3 pins per patient). No significant differences were found between groups. However, statistically significant differences were found regarding time and infection variables. The longer the person had the fixator, the higher the risk of infection, t(x) = 5.49, p = .002. Both chlorhexidine-alcohol and povidone-iodine solutions are equally effective antiseptic agents for the prevention of infections in external fixators.

Cáncer mamario y cervicouterino: el problema del absentismo femenino en la acción preventiva / Breast and cervical cancer: the problem of the lack of preventive actions in women

Introducción: La prevalencia del cáncer es un problema que vas más allá de la preocupación médica, por cuanto involucra aspectos subjetivos y sociales en la vida de quienes lo padecen o están en riesgo. Por esto, es de gran importancia detectarlo tempranamente, especialmente entre mujeres debido a su exposición a los factores de riesgo de cáncer de mama y cérvix. Objetivo: Analizar la abstención femenina en Chile a la Mamografía y Papanicolaou. Materiales y métodos: Se realizó un análisis multivariado de regresión logística binomial, de los datos disponibles en el Módulo de Salud de la Encuesta de Caracterización Socioeconómica Nacional (CASEN) en su edición del año 2015. Resultados: Se expone una generalizada abstención a la acción preventiva entre mujeres, aun cuando la prevalencia de ambos tipos de cáncer es alta. Los motivos personales aparecen como los más comunes para omitir Mamografía y/o Papanicolaou, especialmente la subvaloración de su importancia. Los factores que aumentan la probabilidad de abstención son la baja escolaridad, la ausencia de afiliación médica y la presencia de pareja. Conclusiones: Se plantea la necesidad de aumentar igualmente la cobertura del servicio preventivo, focalizar los recursos hacia la población vulnerable y mejorar las estrategias de incentivo hacia estos exámenes.

Introduction: The prevalence of cancer is a problem that goes beyond medical concern since it involves subjective and social aspects that affect the lives of those who either suffer from cancer or are at risk for it. Therefore, it is important to detect it early, especially among women due to their exposure to risk factors for breast and cervical cancer. Objective: To analyze women's abstention from mammography and Papanicolaou screening in Chile. Materials and methods: A multivariate binomial logistic regression analysis was conducted with available data from the Health Module of the National Socioeconomic Characterization Survey (NSCS) from 2015. Results: Even though there is a high prevalence of both types of cancer, there is a generalized female abstention from preventive actions. Personal reasons are the most common justifications given for avoidance of mammography and/or Papanicolaou test, especially undervaluing their importance. Factors that increase the probability of abstention include low education level, lack of medical affiliation, and presence of a partner. Conclusions: It is important to increase the coverage of preventive services, focus resources towards vulnerable populations, and create incentive strategies for women to take these exams.

Influence of Socio-Economic Status on Psychopathology in Ecuadorian Children.

The socioeconomic status (SES) of parents has been reported to have a crucial impact on emotional competence in childhood. However, studies have largely been carried out in developed countries and in children in a specific age range, and it is not clear whether the effect of the SES of parents varies by age. The objective of this study was to investigate the psychopathological profile (including externalizing and internalizing problems) of children aged 7, 9, and 11 years old with low SES in a developing country (Ecuador). The study included 274 children (139 boys and 135 girls), who were divided between medium-SES (n = 133) and low-SES (n = 141) groups. Data were gathered on socioeconomic and anthropometric variables of the children, and the parents completed the Child Behavior Check-List (CBCL). In comparison to the medium-SES group, children in the low-SES group obtained higher scores for internalizing and externalizing symptoms and for total problems, and they obtained lower scores for social competence skills. The housing risk index and school competence were the two main predictors of internalizing and externalizing problems in this population.
