Considering the advances made on mucopolysaccharidosis type I after the consensus study published by a group of experts in Argentina in 2008, recommendations about genetic testing, cardiological follow-up, airway care, hearing impairment detection, spinal and neurological conditions, as well as current treatments, were reviewed. Emphasis was placed on the need for early diagnosis and treatment, as well as an interdisciplinary follow-up.Chronic hepatitis B virus infection is one of the most prevalent diseases worldwide. It may progress to cirrhosis and hepatocellular carcinoma. An early detection, not using intravenous drugs, sex education, and immunization are critical for prevention. An infection in the neonatal period and in the first year of life becomes chronic in more than 90 % of children. Vertical transmission from a mother with hepatitis B virus to the newborn infant is currently the most common mode of transmission. Detection, immunoglobulin administration, and immunization help to reduce it. Antiviral therapy may accelerate the transition from the active to the inactive phase of infection by two or three years, without affecting the recovery process. A timely treatment of some selected cases may prevent hepatitis B progression.In our daily medical practice, we are constantly facing situations that require a comprehensive view of the patient, based not only on scientific knowledge, but also encompassing relevant legal, anthropological, philosophical, and sociological concepts. This can be summarized by saying that bioethical knowledge and training are critical in current professional practice. This will allow us to provide quality care while contributing to a paradigm change in health sciences. The objective of this article is to review concepts such as person, dignity, and best interests of the child, and reflect on the importance we give to them in our professional practice. Barriers in communication between physicians and Deaf or hard of hearing people may be risk factors for health. The services of a professional Argentine Sign Language interpreter (PASLI), by virtue of Act No. 26378, may mitigate this. To estimate the proportion of pediatricians who have knowledge of Act No. 26378 and whether this is associated with the recommendation of a PASLI. Cross-sectional study with a selfadministered electronic questionnaire among pediatricians members of the Sociedad Argentina de Pediatría who practiced in the Autonomous City of Buenos Aires (CABA). A total of 381 surveys were assessed. Of these, 15.1 % knew the Act, and this was associated with the recommendation of a PASLI (OR 3.7; 95 % CI 1.1-12.9; p < 0.05). The proportion of pediatricians working in CABA who knew the Act was 15.1 %. This was significantly associated with the recommendation of a PASLI.The proportion of pediatricians working in CABA who knew the Act was 15.1 %.

We aimed to evaluate the relationship between abdominal subcutaneous fat thickness (ASFT) and hepatic steatosis, serum lipid and transaminase levels in obese children. A retrospective study was conducted with children (aged 4-18 years) who presented to outpatient clinic due to obesity. Associations between ASFT as assessed by ultrasonography (US) and hepatic steatosis, alanine transaminase (ALT), aspartate transaminase (AST) and serum lipid profile were evaluated. We identified 95 children, all of which were diagnosed as having hepatic steatosis; the most common type was grade 1 (73.6 %, n 70), followed by grade 2 (21.1 %) and grade 3 (5.3 %). The mean values of midline and flank ASFT were measured as 38.48 ± 11.53 mm and 20.91 ± 8.00 mm in grade 1; 41.23 ± 10.03 and 19.84 ± 6.75 in grade 2 and 63.12 ± 12.08 and 23.22 ± 5.92 in grade 3 hepatic steatosis, respectively. Midline and flank ASFT correlated positively with triglycerides in grade 3 steatosis, while midline ASFT correlated with body mass index, total cholesterol, low-density lipoprotein cholesterol, and AST (r 0.9; p 0.037; r 0.648, p 0.001; r 0.387, p 0.001; r 0.406, p 0.001, r 0.463, p 0.001; respectively) in grade 1 steatosis. ASFT as assessed by US may be of predictive value for hyperlipidemia in grade 3 and for hypercholesterolemia in grade 1 hepatic steatosis in obese children.ASFT as assessed by US may be of predictive value for hyperlipidemia in grade 3 and for hypercholesterolemia in grade 1 hepatic steatosis in obese children. Previous studies have found that excessive screen time or early screen exposure is associated with poor attention, lack of behavioral control, delayed language and deficit in executive functions. The aim of this study was to investigate the relationship between screen time and emotion regulation skills, which is one of the important life components affecting the social relations of children aged 2 to 5 years. This cross-sectional descriptive study was carried out in a university hospital between January 1, 2018 and March 1, 2018. Foxy-5 Mothers of healthy children aged 2-5 years with a daily screen time of less than 1 hour or over 4 hours were included in the study. A structured survey and the Emotion Regulation Checklist for parents were applied to the mothers who agreed to participate. Of 240 children participating in the study, 98 (40.8 %) had ≥4 hours of screen time. Caring by mother, age at first screen exposure 12 months and older, not co-viewing with parents were found to be associated with ≥ 4 hours of screen time (p = 0.002, p = 0.002, p = 0.012, respectively). The ratio of participants with highlability/ negativity (L/N) score was significantly higher in children with screen time of ≥ 4 hours and not co-viewing with parents (p = 0.004, p = 0.033, respectively). This study investigating the relationship between the emotion regulation skill and screen time revealed that excessive screen time is associated with emotional lability in this early childhood period.This study investigating the relationship between the emotion regulation skill and screen time revealed that excessive screen time is associated with emotional lability in this early childhood period.
