Question: Have polycystic ovary syndrome (PCOS) increased risk of having an offspring with attention-deficit/hyperactivity disorder (ADHD)? Finding: Six articles (3 cohort and 3 case-control studies; 401,413 total ADHD cases) met the study criteria. Maternal PCOS was associated with an increased risk of ADHD in the offspring based on odds ratio (OR) and relative ratio (RR) (OR, 1.42; 95% confidence interval [CI], 1.27–1.57) and (RR, 1.43; 95% CI, 1.35–1.51), respectively. Meaning: Our study showed that maternal PCOS is a risk factor for ADHD. |

Paroxysmal nonepileptic events (PNE) comprise of a variety of nonepileptic behaviors and are divided into various types. A more accurate diagnosis is possible by examining the video clip provided by the caregiver. In infants, physiologic PNE accounts for the majority of the PNE. It is important to exclude epilepsy, for which blood tests, electroencephalography, and imaging tests can facilitate differential... |

Behavioral therapy, the most widely proven intervention for the core symptoms of autism spectrum disorder (ASD), is required for life for individuals with ASD. Parent involvement, early detection, and early therapy play important roles. We must organize the risk factors for ASD and develop a screening tool that can be easily applied in the clinical, daycare, or school setting. |

• Psychogenic non-epileptic seizures (PNES) are events that look like epileptic seizures but are not caused by abnormal electrical discharges. • PNES are a manifestation of psychological and emotional distress. • Treatment for PNES does not begin with the psychological intervention but starts with the diagnosis and how the diagnosis is delivered. • A multifactorial biopsychosocial process and a neurobiological review are both essential components when treating PNES |

Bayesian false-discovery probability and false-positive report probability are the 2 major Bayesian methods used to evaluate noteworthiness of a genetic variant. Application of stricter P value is needed to confirm statistical significance in meta-analyses. Gene network analysis of noteworthy genetic variants shows a blueprint of the genetic background in complex diseases. |

Acute fulminant myocarditis (AFM) occurs as an inflammatory response to an initial myocardial insult. Its rapid and deadly progression calls for prompt diagnosis with aggressive treatment measures. The demonstration of its excellent recovery potential has led to increasing use of mechanical circulatory support, especially extracorporeal membrane oxygenation (ECMO). Arrhythmias, organ failure, elevated cardiac biomarkers, and decreased ventricular function at presentation... |

Neurofibromatosis type 1 (NF1), a prevalent genetic disease that is transmitted in an autosomal dominant manner, is characterized by multiple cutaneous café-au-lait spots and neurofibromas as well as various degrees of neurological, skeletal, and neoplastic manifestations. The clinical features of NF1 increase in frequency with age, while the clinical diagnosis can remain undetermined in some pediatric patients. Importantly, affected patients... |

In this article, a systematic review of reported primary immunodeficiency disease (PID) cases in Korea was performed and we attempted to estimate the number of PID patients and healthcare costs for the first time in Korea. Our review revealed that Korean PID cases are greatly underreported in the literature based on health insurance. Physicians in the field and health care policymakers should be aware of the disease burden of PID. |

Question: Can CXC chemokine receptor 2 (CXCR2) antagonist preserve alveolarization by attenuating the inflammation induced by systemic lipopolysaccharide (LPS) administration in a rat model of bronchopulmonary dysplasia (BPD)? Finding: CXCR2 antagonist significantly decreased neutrophil counts in bronchoalveolar lavage fluid and peripheral blood induced by systemic LPS administration and restored alveolarization in newborn rats. Meaning: CXCR2 antagonist protected the lungs from the inflammation in a rat model of BPD. |

Although Helicobacter pylori infection rate in children is unclear due to diversity and limitation of diagnostic tests unlike in adults, investigation the childhood prevalence is important for predicting H. pylori-related diseases in the future. H. pylori infection occurred in early childhood, and declined during 30 years in our study. Change in risk factors of H. pylori transmission and consensus for eradication therapy in children might further reduce the infection rate. |
