A 36-year-old female was transferred to our emergency medical center with decreased mental status after a 6.0 g propafenone overdose because of domestic disturbance. She had no previous history of epilepsy, diabetes mellitus, hypertension or psychiatric illness. Before presenting to our center, gastrointestinal decontamination, charcoal administration, and endotracheal intubation due to bradycardia and generalized seizure had been performed. Soon after hospital arrival, at 5 h after ingestion, she collapsed into shock and fatal arrhythmia. We successfully resuscitated the patient with amiodarone, sodium bicarbonate, a large volume of normal saline, calcium, and ventilator care. At 23 h after ingestion, she was fully recovered and had no subjective signs or symptoms. To our knowledge, this is the first case report of intentional propafenone overdose in Korea, which we report with reviews of the previous literature.

The purpose of this study was to introduce the radiography for the natural course and clinical diagnosis of foreign body ingestion and aspiration, to help diagnosis and treatment, to evaluate the accuracy of radiographic images of pediatric patients. A 2 to 7 year-old patient who ingested a foreign body was ingested and aspirated with foreign substances such as coin, cloth pin, earring, baduk stone, and hairpins, and chest and abdomen of the plain radiography. The pediatric patient who ingested and aspirated the foreign body of the coins, the clothespins, the earrings, the stones, and the hairpins were examined by chest and abdomen of the plain radiography and fluoroscopic images. The radiography examination can be combined to effectively cope with the treatment and the treatment of the foreign substance removal. It can be applied to the diagnosis of foreign body in pediatric patient's clinic and appropriate treatment and treatment direction.

Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder of hyperphagia leading to severe obesity, intellectual deficits, compulsivity, and other behavioral problems. PWS is caused by the inactivation of contiguous genes on chromosome 15q11-q13, which complicates the development of targeted, effective therapeutics. Various preclinical studies have been conducted by developing mouse models that exhibit phenotypes similar to PWS. Oxytocin deficiency in PWS is associated with hyperphagia with impaired satiety and, food-seeking and behavior disorders. Here, we summarize the oxytocin study of ingestion behavior tested in the PWS mouse model and published data from clinical trials that have evaluated treatment effectiveness on ingestion behavior and social dysfunction in patients with PWS.

Ingestion of foreign bodies (FBs) is a common phenomenon among young children. Plain radiography is the first step diagnostic modality to detect the radio-opaque FBs. And computed tomography has been recommended by several guidelines as useful modalities for diagnosing ingested FBs. However, there is a risk of radiation exposure, making it burdensome to use in asymptomatic patients. Ultrasound (US) is not a commonly used technique for diagnosing ingested foreign bodies. However, US can provide real-time imaging with good resolutions without radiation exposure in pediatric patients. Herein, we report two pediatric cases of metallic foreign body ingestion that were successfully diagnosed using US for localizing foreign bodies. This study indicates that US may be used as an alternative method for detecting the localization of metallic foreign bodies in the gastrointestinal tract without exposure of radiation, particularly in pediatric patients.

Larvae from the marine medaka fish Oryzias javanicus were exposed with polystyrene microplastics (MPs) for 24 h. Exposure to waterborne fluorescent MPs showed clear ingestion and egestion in feces. Under constant MPs, the concentration of dissolved oxygen significantly decreased in 24 h compared to the control. Significant intracellular reactive oxygen species and malondialdehyde contents were detected in larvae, indicating oxidative stress and lipid peroxidation. Significant elevations in mRNA expressions of heat shock protein 70 and antioxidant defense system genes (glutathione reductase, glutathione peroxidase, catalase, and superoxide dismutase) were measured with increases in enzymatic activity of oxidative stress-related proteins. Taken together, the alterations to the molecular and biochemical components suggested that waterborne MPs had an oxidative stress effect on marine medaka larvae.

Foreign body (FB) ingestion is a common health problem that affects children more than adults. According to gastroenterologists' guidelines, the management of FB ingestion differs slightly between adult and children. This review aimed to compile adult and children guidelines and establish an understandable association to reveal the requirements and timing of the endoscopic procedure, which is the most effective and least complicated technique for gastrointestinal FBs. Coins, pins, and chicken and fish bones have been the most commonly ingested FBs. However, with their increasing use in recent years, large batteries with lithiumion conversion, stronger magnets composed of rare earth metals, such as neodymium, and superabsorbent objects have become the most morbid and mortal, necessitating new management strategies. Although the approach to gastrointestinal FBs is controversial, with different treatment options available in different disciplines, many studies have demonstrated the efficacy and safety of endoscopic procedures. Many factors influence the timing of endoscopy, including the nature, size, and location of the ingested object and the patient's clinical condition.
