In practice, it is very common to associate monochorionic (MC) twin pregnancies with complex or complicated pregnancies, using both terms interchangeably. However, these are not synonyms; dynamism is the protagonist in complex systems, but not in complicated ones. In order to understand a MC pregnancy as a complex system, it is necessary to first look into its main characteristics. The placenta is one of the main sources of problems. Then, the MC pregnancy has to be analyzed from the perspective of complexity, identifying the system characteristics and its complications as emergent properties.

Introduction. The COVID-19 pandemic has had a profound impact on the health of young people worldwide, especially on people with eating disorders (EDs) due to the stress, anxiety, and changes experienced in access to health care. Objective. To explore adolescents' perceptions on changes in their social ties and the modalities of health care for patients with EDs. Population and methods. Qualitative study using in-depth interviews with adolescents with EDs seen at a teaching hospital during the COVID-19 pandemic. Results. Fifteen adolescents were interviewed; their mean age was 18 years; 93% were girls. Anorexia nervosa was observed in 86.6%. The most relevant negative aspects perceived were discomfort with family life (80%) and dissatisfaction with social media content regarding body image and dieting (73%). The aspects perceived as positive were peer support (66%) and improvements in eating habits (66%). The main change identified regarding the management before the COVID-19 pandemic was online followup by the mental healthcare team (73%). Conclusion. The adolescent population with EDs during the mandatory social isolation period reported discomfort with family life and dissatisfaction with social media content regarding body image and dieting. Notwithstanding this, adolescents highlighted peer support and improvements in their eating habits as positive aspects.

Introduction: The age at which children are introduced to media devices is becoming increasingly earlier. Studies regarding the media habits of young children have gained importance. The aim of the study was to describe the screen media habits (age of introduction media, time spend with screen, popular choices) of preschool children and to explore their relationship with household characteristics. Population and methods: Cross-sectional descriptive study; the parents of children aged 36-72 months who attended childcare centers in Kayseri, a central Anatolian city in Türkiye, completed a questionnaire on media habits of families and children. Results: There were 858 questionaires included. The proportion of children using screen media more than 2 h/day was 28%; 36% of children were introduced to media devices before the age of two. The most frequently used media tool was television (95%) and the program watched was cartoons for TV (86.7%). Children of highly educated parents had shorter TV, computer and smartphone screen time (p = 0.012, p = 0.007, p <0.01 for mother and p = 0.049, p = 0.032, p = 0.04 for father respectively). Introducing books in the first 6 months was associated with shorter daily screen time (p = 0.011, p = 0.009, p = 0.002 for TV, computer and smartphone ,respectively). Parent's time spent on TV was positively correlated with children's time spent on TV (p <0.05, r = 0.354). Conclusion: Parents' education levels, parents' screen time and introducing book in early age was related to children's media habits. Comprehensive studies are needed to explain this relationship more clearly.

Down syndrome, or trisomy 21, has a higher mortality than the general population, mainly due to respiratory tract infections. The objective of this study was to describe immune compromise in a series of cases of patients with Down syndrome referred to the Pediatric Immunology Section due to recurrent infections or pathological laboratory findings between 6/1/2016 and 5/31/2022. Here we describe immune compromise in 24 patients. Twelve patients failed to develop a polysaccharide response and received antibiotic chemoprophylaxis, or gamma globulin replacement therapy. Three patients developed agammaglobulinemia with presence of B cells and gamma globulin replacement therapy was indicated. Nine patients had T-cell lymphopenia and 1 patient, combined immune compromise.

Interstitial lung diseases are rare in pediatrics. They include dysfunctions in the metabolism of pulmonary surfactant, an amphipathic molecule that reduces surface tension and prevents alveolar collapse. Here we describe the case of a 6-month-old infant controlled for low weight, who presented with acute respiratory distress and cyanosis; his chest X-ray showed interstitial infiltrate, pneumomediastinum, and bilateral pneumothorax. During history-taking, it was noted that his mother had a history of hospitalization at 1 year old with unknown diagnosis, requiring prolonged oxygen therapy; she now shows signs of chronic hypoxia. The patient was hospitalized and required oxygen therapy. Ancillary tests were done to look for the etiology of the condition, with no positive results. A chest computed tomography showed groundglass opacities, thickening of the septal interstitium, and areas of air trapping; based on the results of a lung biopsy and a genetic study, pulmonary surfactant metabolism dysfunction was diagnosed.

Maternal mental health problems during pregnancy, childbirth, and the postpartum period are a challenge for public health. Not recognizing them hinders a timely diagnosis and treatment and has an impact on the mother and the establishment of the fundamental bond of the mother-child dyad. We must recognize the risk factors (age, socioeconomic status, mental health history, family dysfunction, unfavorable environment), clinical manifestations, and screening tools. There is evidence that the effect of stress, anxiety, and depression during pregnancy negatively affect fetal neurodevelopment and condition child developmental outcomes. Here we describe the negative impact of postpartum depression during the first months of life, which affects mother-child bonding, postnatal development (emotional, behavioral, cognitive, language), and the maintenance of breastfeeding. We also recognize protective factors that mitigate its effects. It is essential to establish preventive strategies and interdisciplinary diagnostic and therapeutic approaches to minimize the risks to the mother and her children.

Langerhans cell histiocytosis is an expression of myeloid dendritic cells, associated with a significant inflammatory component and varied systemic involvement. The most common age at presentation is between 1 and 4 years, and it prevails among male subjects. Here we describe the case of a 5-year-old boy who presented with a granulomatous lesion with perianal fistula and lung and external ear involvement. An interdisciplinary approach helped to make a diagnosis, provide the necessary interventions, and start an adequate treatment.
