Persistent Left Superior Vena Cava and Inferior Vena Cava Dual Drainage to Coronary Sinus: A Case Report.

Dilation of the coronary sinus is often a result of excessive volume overload from congenital anomalies of systemic venous return to the heart. These abnormalities are often discovered incidentally later in life when a patient requires cardiac imaging, cardiac catheterization, or thoracic surgery. The most common abnormality is a persistent left superior vena cava. Inferior vena cava malformation is less common, yet several different anomalies can arise. The presence of persistent left superior vena cava or inferior vena cava anomalies requires further evaluation to rule out congenital heart disease in infants. Knowledge of technically challenging systemic venous anatomy is beneficial prior to procedures necessitating central venous access such as a central line, cardiac catheterization, and intracardiac device implantation. We present an unusual case of persistent LSVC and IVC both draining directly into a severely dilated coronary sinus that was diagnosed by fetal echocardiogram and later confirmed postnatally by transthoracic echocardiogram and computed tomography angiography. To our knowledge this is the second reported case of IVC drainage into the CS and the first case that reports this as a prenatal diagnosis.

Childhood sleep: assessments, risk factors, and potential mechanisms.

BACKGROUND: Sleep problem is a highly prevalent health issue among pediatric populations across the world. In this review, we aimed to identify risk factors contributing to sleep deficiency and poor sleep hygiene in children. Potential biological, psychosocial, and environmental mechanisms as well as research gaps in the literature are also discussed. DATA SOURCES: A comprehensive search for relevant English language full-text, peer-reviewed publications was performed focusing on pediatric sleep studies from prenatal to childhood and adolescence in a variety of indexes in PubMed, SCOPUS, and Psych Info. Both relevant data based and systematic reviews are included. RESULTS: This paper summarizes many risk factors for childhood sleep problems, including biological (e.g., genetics, gender, age and puberty, prenatal factors, postnatal factors); nutritional (e.g., macronutrients, micronutrients, omega-3 fatty acids, obesity); environmental (e.g., heavy metals, noise, light, air pollution); interpersonal (e.g., family, exposure to violence, screen media use, physical injury); and community/socioeconomic variables (e.g., racial/ethnicity and cultural factors, neighborhood conditions and socioeconomic status, school factors, public health disasters/emergencies), to better understand the development of sleep problems in children. CONCLUSIONS: Poor childhood sleep is a multifactorial issue affected by a wide range of prenatal and early-life biological, environmental, and psychosocial risk factors and contributors. A better understanding of these risk factors and their mechanisms is an important first step to develop future research and prevention programs focusing on pediatric sleep problems.

Childhood sleep: physical, cognitive, and behavioral consequences and implications.

BACKGROUND: Sleep problems in children have been increasingly recognized as a major public health issue. Previous research has extensively studied and presented many risk factors and potential mechanisms for children's sleep problems. In this paper, we aimed to identify and summarize the consequences and implications of child sleep problems. DATA SOURCES: A comprehensive search for relevant English language full-text, peer-reviewed publications was performed focusing on pediatric sleep studies from prenatal to childhood and adolescence in a variety of indexes in PubMed, SCOPUS, and Psych Info published in the past two decades. Both relevant data-based articles and systematic reviews are included. RESULTS: Many adverse consequences are associated with child sleep deficiency and other sleep problems, including physical outcomes (e.g., obesity), neurocognitive outcomes (e.g., memory and attention, intelligence, academic performance), and emotional and behavioral outcomes (e.g., internalizing/externalizing behaviors, behavioral disorders). Current prevention and intervention approaches to address childhood sleep problems include nutrition, exercise, cognitive-behavioral therapy for insomnia, aromatherapy, acupressure, and mindfulness. These interventions may be particularly important in the context of coronavirus disease 2019. Specific research and policy strategies can target the risk factors of child sleep as well as the efficacy and accessibility of treatments. CONCLUSIONS: Given the increasing prevalence of child sleep problems, which have been shown to affect children's physical and neurobehavioral wellbeing, understanding the multi-aspect consequences and intervention programs for childhood sleep is important to inform future research direction as well as a public health practice for sleep screening and intervention, thus improving sleep-related child development and health.

Natural History of Bilateral Congenital Absence of the L4 Pedicles.

CASE: A 5-month-old girl was diagnosed with congenital bilateral absence of the L4 pedicles and an absent right kidney. She developed a right thoracic scoliosis at age 3 that was treated with a brace. At her most recent follow-up at age 16, she was skeletally mature and had a residual 20° right thoracic scoliosis. She was pain-free, had a normal neurological examination, and was fully active. CONCLUSION: This case presents a long-term follow-up of a patient with congenital bilateral absence of L4 pedicles. She developed scoliosis that was successfully treated with bracing. No other significant issues developed over 15 years of follow-up.
