Lymphatic malformations in cases with macrocystic lesions can be treated with surgical excision or sclerotherapy using alcohol, bleomycin, doxycycline, or OK-432. We report a case of a 24-year-old woman who underwent percutaneous drainage and povidone-iodine sclerotherapy as primary treatment for cervical lymphatic malformation. The patient underwent povidone-iodine sclerotherapy for 3 consecutive days. After 8 months, ultrasonography of the lesion in the neck revealed complete resolution of the cervical lymphatic malformation without any complication...

John Hoon Rim, Jeong A Kim, Jongha Yoo
Only 6 patients with partial trisomy of the long arm of chromosome 19 (19q), caused by direct interstitial duplications, have been reported until today. Herein, we report a pediatric patient with a novel 1.13 Mb direct interstitial duplication within 19q13.32, which is the smallest fragment affected so far. A five-year old Korean boy of healthy parents presented with microcephaly, growth retardation, developmental delay, and craniofacial dysmorphism. Even though G-banded chromosome analysis at resolution of 550-band revealed normal karyotype, duplication of 1...

Left atrial appendage (LAA) occlusion can be employed as an alternative treatment to oral anticoagulation in patients with atrial fibrillation to prevent embolic events. Atrial septal defect (ASD) may be related with right heart dysfunction and allow paradoxical embolism to occur. However, occlusion of both LAA through atrial access with ostium secundum ASD and ASD in the same setting is unusual. Therefore, we report a case in which a LAA and an ASD was sequentially occluded.

PURPOSE: Adverse drug events (ADEs) are associated with high health and financial costs and have increased as more elderly patients treated with multiple medications emerge in an aging society. It has thus become challenging for physicians to identify drugs causing adverse events. This study proposes a novel approach that can improve clinical decision making with recommendations on ADE causative drugs based on patient information, drug information, and previous ADE cases. MATERIALS AND METHODS: We introduce a personalized and learning approach for detecting drugs with a specific adverse event, where recommendations tailored to each patient are generated using data mining techniques...
