[One hundred years of health in a demographic, epidemiological and public policy context: the transition of childhood morbidity and its challenges]. / Cien años de salud en un contexto demográfico, epidemiológico y de políticas públicas: la transición de la morbilidad infantil y sus desafíos.

Chile is in an advanced stage of demographic and epidemiological transition. It is in this scenario that the political, economic and health crisis occurred, with the social outbreak in 2019 and then the COVID-19 pandemic. The mortality of children and adolescents dropped significantly, however, changes in lifestyles and demotivation, associated with long confinement and worsening health of parents and caregivers triggered an epidemic of mental health, developmental and nutritional problems. Pediatricians were forced to reinvent themselves, exposing themselves to stress and burnout. The aim of the manuscript is to describe the demographic, epidemiological and public policy context of child health in Chile in the last century, as a backdrop to dimension the immediate impact of the COVID-19 pandemic. The new health challenges for this age group in the medium and long term are discussed. Some theories, conceptualizations, and relevant milestones of the public health system in Chile are presented. The emergence of "post-pandemic morbidity", such as sedentary lifestyle, food insecurity, screen addiction, identity conflicts, violence, mental health disorders and reemergence of morbidity and mortality due to infectious and contagious diseases is discussed. Professionals responsible for the care of children must redouble their efforts to provide comprehensive care, accompanying families in the new challenges, in order to rehabilitate a healthy childhood.

[Revista Chilena de Pediatría/Andes Pediatrica in the new millennium. Bibliometric analysis]. / Revista Chilena de Pediatría/Andes Pediatrica en el nuevo milenio. Análisis bibliométrico.

INTRODUCTION: Andes Pediatrica/Revista Chilena de Pediatría (AP/RChP), maintains a document profile that covers all scientific publication formats, from Original Articles (OAs) to Letters to the Editor. Adequate editorial planning requires a long-term bibliometric analysis. OBJECTIVE: To describe the profile of OAs published in AP/RChP in the last two decades. METHODOLOGY: From a controlled vocabulary list, the thematic and methodological descriptors of the documents from 2000 to 2020 were standardi zed. Nationality, sex, and profession of the authors, document typology, and design of the OAs were analyzed, as well as the descriptors cited in Google Scholar and the most visited descriptors on the journal's website in recent years. RESULTS: 1738 manuscripts were published, 580 (33.4%) were OAs, with an increase from 59 to 129 OAs between the first and last three years. The average number of authors was higher for OAs (4.7) than for non-originals (3.0). In 2020, there were nine multicenter collaborations from different countries. The number of OAs by foreign authors increased from 3.3% to 28.7%, the first authorship by non-medical professionals increased from 15% to 31%, and there was a predominance of female first authors (ratio 1.4/1). Of the OAs, 9.1% were experimental, 3.3% were qualitative and the rest were quantitative observational. The most published descriptors were Nutrition, Infectious Diseases, Neonatology, and Pneumonology, while the most cited descriptors were Nutrition, Neonatology, and Oral Health, with no trend among the most visited. 44% of the most cited articles and 35% of the most visited articles were OAs. CONCLUSIONS: A significant increase in published OAs stands out, with a low frequency of experimental designs. Authors of different na tionalities and professions participated. OAs represent one-third of the visits and almost half of the citations, with no correlation between the most published and most cited descriptors.

Nistagmo secundario a albinismo con compromiso ocular en paciente femenina: un desafío diagnóstico / Nystagmus secondary to albinism with ocular involvement in a female: a diagnostic challenge

INTRODUCCIÓN: El nistagmo infantil es infrecuente y representa un desafío diagnóstico para el pediatra. El albinismo es una de sus principales causas, siendo difícil de sospechar en ausencia de compromiso cutáneo evidente, especialmente en pacientes femeninas, debido a que tipo de herencia del albinismo ocular. OBJETIVO: Describir un caso de nistagmo secundario a albinismo con compromiso ocular aislado en paciente femenina, para discutir el enfoque diagnóstico pediátrico. CASO CLÍNICO: Paciente fe menino de 3 semanas de vida, sin antecedentes mórbidos, derivada a neuropediatra y oftalmólogo por movimientos oculares paroxísticos desde las 2 semanas, con estudio con electroencefalograma e imágenes cerebrales normales. A los 3 meses se confirmó translucencia iridiana, nistagmo y astigmatismo hipermetrópico. La valuación dermatológica descartó compromiso cutáneo. Evolucionó con inclinación cefálica hacia abajo y retraso del desarrollo de la coordinación, fue manejada con lentes de corrección y kinesioterapia. A los 3 años, destacaba mejoría de la agudeza visual, disminución del nistagmo y neurodesarrollo normal. La evaluación oftalmológica de ambos padres fue normal y no había antecedentes de nistagmo o albinismo en la familia. Por decisión de los padres no se realizó estudio genético. CONCLUSIÓN: El diagnóstico de nistagmo secundario a compromiso ocular del albinismo, aún en ausencia de afección cutánea, es clínico; el estudio genético permite confirmar la etiología, sin ser un examen imprescindible, a menos que se considere la planificación familiar. La pesquisa oportuna e intervención multidisciplinaria determinan un mejor pronóstico.

INTRODUCTION: Infantile nystagmus is an infrequent condition that represents a diagnostic challenge for the pediatri cian. Albinism is one of its main causes, being difficult to suspect in the absence of evident cutaneous involvement, especially in female patients, due to the inheritance type of ocular albinism. OBJECTIVE: To describe a case of nystagmus secondary to albinism with isolated ocular involvement in a female patient, in order to provide tools for pediatric approach and diagnosis. CLINICAL CASE: Three- weeks-old female patient, without morbid history, referred to a pediatric neurosurgeon and ophthal mologist due to paroxysmal eye movements since 2 weeks of age. The electroencephalogram and brain images were normal. In follow-up monitoring at 3 months, iris translucency, nystagmus, and hypermetropic astigmatism were confirmed. Dermatologic evaluation ruled out cutaneous invol vement. The patient developed cephalic downward inclination and coordination development de lay was confirmed, the patient was handled with corrective lenses and kinesiotherapy. In follow-up monitoring at 3 years, there was an improvement in visual acuity, decreased nystagmus and normal neurodevelopment. The ophthalmological evaluation of both parents was normal and there was no history of nystagmus or albinism in the family. Upon her parents' decision, no genetic study was ca rried out. CONCLUSION: The diagnosis of nystagmus secondary to ocular albinism, even in the absence of cutaneous involvement, is clinical. The genetic study allows confirming the etiology, without being an essential examination, unless family planning is considered. Timely research and multidisciplinary intervention determine a better prognosis.

[Integrity and misconduct in biomedical research]. / Integridad y conductas inapropiadas en investigación biomédica.

Editorial Boards of mainstream journals occasionally face ethical misconducts in received manus cripts. The Committee on Publication Ethics (COPE) provides recommendations for editors on how to deal with suspected ethical misconduct in either received or published manuscripts. The manus cript is rejected when malpractice is observed during the peer review process, however, if the mis conduct is detected after the publication, the publication will be retracted. The Revista Chilena de Pediatría (Chilean Journal of Pediatrics) has not been exempt from these type of conflicts. In this article, we analyze different aspects regarding the lack of integrity in publications, such as authorship, plagiarism, and conflict of interest. We can conclude that malpractices take place mainly due to the lack of knowledge of the authors rather than intent to defraud. It is expected that this article will suc ceed in instructing and sensitizing our researchers on good practices in research and publication, and contribute, as far as possible, to prevent this actions in the manuscripts sent to our Journal.

Integridad y conductas inapropiadas en investigación biomédica / Integrity and misconduct in biomedical research

Resumen: Los Comités Editoriales de revistas de corriente principal se ven enfrentados ocasionalmente a con ductas éticas inapropiadas en los manuscritos recibidos. El Comité de Ética en las publicaciones (COPE) ofrece recomendaciones para los editores respecto a cómo actuar frente a la sospecha de falta de ética en los manuscritos, ya sea recibidos o publicados. Cuando se pesquisa una mala práctica durante el proceso de revisión por pares, el manuscrito es rechazado, no obstante, si la conducta ina propiada es detectada después de la publicación de manuscrito, se procede a retractar la publicación. Revista Chilena de Pediatría no ha sido exenta a este tipo de conflictos. En este artículo analizamos los distintos aspectos relacionados con la falta de integridad de las publicaciones, como son las autorías, el plagio y el conflicto de intereses. Podemos concluir que las malas prácticas ocurren principalmente por desconocimiento de los autores, más que por intención de fraude. Se espera que el presente ma nuscrito logre instruir y sensibilizar a nuestros investigadores, respecto a las buenas prácticas en la investigación y publicación, y, contribuir, en lo posible, a prevenir que estas acciones ocurran en los manuscritos enviados a nuestra Revista.

[Lumbar hypoplasia associated to thoracolumbar kyphosis in infants. Anatomic variant? Clinical cases]. / Hipoplasia vertebral asociada a cifosis toracolumbar en lactantes ¿variante anatómica? Casos clínicos.

INTRODUCTION: Vertebral hypoplasia is an anomaly of the vertebral bodies, in which they present a wedge shape, usually at the level of the thoracolumbar junction. Although it is associated with cer tain storage diseases and bone dysplasias, it is also possible to find isolated vertebral hypoplasia it in healthy infants or associated with thoracolumbar kyphosis. The objective of this report is to show the evolution of vertebral hypoplasia associated to kyphosis in two apparently health children. CASE REPORT: Two cases of infants diagnosed with clinically visible lumbar kyphosis when they were sitting. Spine X-rays of both showed lumbar vertebral hypoplasia at L2 level as the only finding. After ruling out other conditions associated with vertebral hypoplasia, conservative management was indicated; in the first case a clinical-radiological follow-up and in the second one, a corset given the magnitude of kyphosis. The evolution was favorable, with complete radiological clinical resolution at the age of 15 months in the first case and clinical regression in the second, in which, at 3 years and 4 months of age, an image of mild vertebral hypoplasia persisted. CONCLUSIONS: Isolated vertebral hypoplasia or associated to kyphosis may be considered a minor anomaly or anatomic variant of infant spine development, however, it requires follow-up until its normalization.
