[Fever of unknown origin: a challenge for the pediatric infectious diseases specialist]. / Síndrome febril prolongado: un desafío para el infectólogo pediatra.

INTRODUCTION: Prolonged febrile syndrome (PFS) is defined as fever 7-10 days, with initial study does not allow etiologic diagnosis. OBJECTIVE: To describe the main causes of the PFS and its temporal behavior in Pediatric Infectious Diseases Unit Outpatient Care of Complejo Asistencial Dr. Sótero del Río (CASR). PATIENTS AND METHODS: A descriptive, prospective study between january 2007-december 2012, about 153 patients from 6 weeks to 14 years 11 months old, diagnosed with PFS, tab completing clinical and laboratory monitoring. RESULTS: etiology was obtained in 67.9%, the causes were infection (88.4%), neoplasms (4.8%), rheumatological (4.8%) and Kawasaki disease (2.8%). The most important infectious causes were enteric fevers (typhoid and paratyphoid) (18.4%), urinary tract infection (11.9%), Bartonella henselae infections and adenovirus (8.7%) each one and Epstein Barr virus (7.6%). Ninety eight percent of patients had complete resolution, 60.7% did not require hospitalization and mortality was 0%. DISCUSSION: As in previous pediatric clinical series the infections were the most frequent causes. Enteric fever persists as principal cause, however, the epidemiological evidence is oscillating in time endorsing the local statistics can count over the years to improve the diagnostic and therapeutic approach.

Does culture shape our understanding of others' thoughts and emotions? An investigation across 12 countries.

Measures of social cognition have now become central in neuropsychology, being essential for early and differential diagnoses, follow-up, and rehabilitation in a wide range of conditions. With the scientific world becoming increasingly interconnected, international neuropsychological and medical collaborations are burgeoning to tackle the global challenges that are mental health conditions. These initiatives commonly merge data across a diversity of populations and countries, while ignoring their specificity. OBJECTIVE: In this context, we aimed to estimate the influence of participants' nationality on social cognition evaluation. This issue is of particular importance as most cognitive tasks are developed in highly specific contexts, not representative of that encountered by the world's population. METHOD: Through a large international study across 18 sites, neuropsychologists assessed core aspects of social cognition in 587 participants from 12 countries using traditional and widely used tasks. RESULTS: Age, gender, and education were found to impact measures of mentalizing and emotion recognition. After controlling for these factors, differences between countries accounted for more than 20% of the variance on both measures. Importantly, it was possible to isolate participants' nationality from potential translation issues, which classically constitute a major limitation. CONCLUSIONS: Overall, these findings highlight the need for important methodological shifts to better represent social cognition in both fundamental research and clinical practice, especially within emerging international networks and consortia.

Social Adaptation in Context: The Differential Role of Religiosity and Self-Esteem in Vulnerable vs. Non-vulnerable Populations - A Registered Report Study.

There is evidence that religiosity and self-esteem are positively related, while self-esteem and religiosity in turn predict successful social adaptation. Moreover, self-esteem has been shown to be directly related to social adaptation in vulnerable contexts. In this registered report study, we tested the hypothesis that religiosity has a positive influence on social adaptation for people living in vulnerable contexts and that self-esteem is a mediator of this relationship. Evidence from this study indicates that neither there is any effect of religiosity on social adaptation nor on self-esteem, independent of whether people live in vulnerable contexts or not.

Metastatic colorectal micropapillary carcinoma presenting as lymphangitic lung carcinomatosis.

Pulmonary lymphangitic carcinomatosis denotes the infiltration of tumor cells into the lung parenchymal lymphatic channels. Breast, lung, stomach, and colon adenocarcinoma are the most common origin of this invasion pattern. The micropapillary variant of colorectal adenocarcinoma has a high rate of lymph node metastases and poor overall survival. A 49 year-old man with a 6 months history of persistent cough and a relevant occupational chemical exposure had a computed tomography that showed bilateral interstitial lung infiltrates. The lung biopsy demonstrated a micropapillary adenocarcinoma with diffusely obstruction of the lung parenchymal lymphatics. The immunohistochemistry confirmed a colorectal origin. The colonoscopy evidenced a mass with identical morphology. Colorectal micropapillary carcinoma with metastatic lung lymphangitic carcinomatosis can occur, as a persistent cough, as presenting symptom in extraordinarily rare cases. To the best of our knowledge, this is the first case of an alive patient with colorectal metastatic micropapillary carcinoma presenting with lymphangitic lung carcinomatosis.

Socio-affective and cognitive predictors of social adaptation in vulnerable contexts.

People living in vulnerable environments face a harder set of challenges adapting to their context. Nevertheless, an important number of them adapt successfully. However, which cognitive and socio-affective variables are specifically related to these variations in social adaptation in vulnerable contexts has not been fully understood nor directly addressed. Here we evaluated socio-affective variables (anxious attachment style, internal locus of control, self-esteem and stress) and cognitive variables (fluid intelligence, crystallized intelligence, working memory, numeracy, probabilistic reasoning and logical reasoning) to explain variations in social adaptation in a sample of 232 adults living in vulnerable contexts (M = 42.3, SD = 14.9, equal amount of men and women). Our results show that an important amount of variance in social adaptation can be explained by socio-affective variables, principally by self-esteem, while cognitive variables also contributed significantly. As far as we know, this is one of the first steps towards understanding the role of cognitive and socio-affective features on social adaptation. In the long run, this area of research could play an important role on the assignation of resources to ease people's integration into society.

[Occult bacteremia in Sótero del Río Hospital: Experience after pneumococcal conjugated vaccine]. / Bacteriemia oculta en niños atendidos en el Complejo Asistencial Dr. Sótero del Río: Experiencia post vacuna neumocóccica conjugada.

BACKGROUND: Occult bacteremia (OB) is one of the possible diagnoses of children younger than 3 years with fever without source in the emergency room. OBJECTIVE: describe OB in the era after introduction of pneumococcal vaccine in Chile. PATIENTS AND METHODS: Prospective descriptive review of data of children with possible OB diagnosis, referred from the emergency department between 2010-2013. RESULTS: Possible OB was diagnosed on 391 patients. 233 had focus, mainly respiratory virus and urinary tract infection. On 158 patients, probable BO was diagnosed, 20 had proven OB from which 15 had positive blood culture for Streptococcus pneumoniae. From these, 7 were fully or partially vaccinated. The serotype was identified on 14 cases: 6 were PCV10 vaccine serotypes (none of them vaccinated), 2 were serotype related (both partially vaccinated) and 6 were non vaccine serotypes (partially or totally vaccinated). DISCUSSION: It is necessary to improve diagnostic methods for respiratory viruses and urinary tract infections and try to expand coverage of pneumococcal conjugated vaccines in the pediatric population in order to reduce the risk of invasive pneumococcal disease in Chile.

Introducción: El síndrome febril prolongado (SFP) se define como fiebre entre 7-10 días, con estudio inicial que no permite un diagnóstico etiológico. Objetivo: Describir las principales etiologías del SFP y su comportamiento temporal en la unidad de infectología pediátrica ambulatoria del Complejo Asistencial Dr. Sótero del Río (CASR). Pacientes y Método: Estudio descriptivo, prospectivo, entre enero de 2007-diciembre de 2012. Análisis de 153 pacientes entre 6 semanas y 14 años 11 meses de edad, con diagnóstico de SFP, que completaron ficha de seguimiento clínico-laboratorial. Resultados: Se obtuvo diagnóstico etiológico en 67,9%, las causas fueron: infecciones (88,4%), neoplasias (4,8%), reumatológicas (4,8%) y enfermedad de Kawasaki (2,8%). Las causas infecciosas más importantes fueron: fiebres entéricas (tifoidea y paratifoidea) (18,4%), infección del tracto urinario (11,9%), enfermedades por Bartonella henselae y adenovirus (8,7%) cada uno y virus de Epstein Barr (7,6%). El 98% de los pacientes tuvo resolución completa, 60,7% no requirió hospitalización y no se registraron decesos. Discusión: Como en las series clínicas antes publicadas, las infecciones fueron la causa más frecuente de SFP. La fiebre entérica persiste como causa principal; sin embargo, se evidencia una situación epidemiológica oscilante en el tiempo justificando la necesidad de contar con estadísticas locales a lo largo de los años para mejorar el enfoque diagnóstico y terapéutico.
