ABSTRACT
Vasculitis is a systemic disease, characterized by inflammation of the vascular wall. Although rare, it is sometimes life-threatening due to diffuse pulmonary hemorrhage or acute glomerulonephritis. Besides primary vasculitis, whose cause is unknown, numerous conditions such as autoimmune diseases, drugs, infections, and tumors can cause secondary vasculitis. Vasculitis displays various non-specific symptoms, signs, and laboratory findings; hence, diagnosis of the disease requires integration of various results including clinical features, imaging findings, autoantibody tests, and pathological findings. In this review, we have discussed the clinical, radiologic, and pathological features of vasculitis. Further, we elaborated the imaging findings and differential diagnosis of typical vasculitis that frequently involves the lung and introduced a new international classification of vasculitis, the Diagnostic and Classification Criteria in Vasculitis.

ABSTRACT
BACKGROUND: Pediatric palliative care (PPC) is the active total care of children suffering from life-threatening illnesses. Palliative care includes symptom management, psychosocial support, and end-of-life care. Despite significant advances in disease diagnosis and treatment, resources for PPC of children with serious illnesses are limited in Korea. This study aimed to investigate the scale, time trends, disease composition, regional distribution, and unmet needs of children dying from complex chronic conditions (CCCs). METHODS: We examined available information on children who died of CCCs from 2005 to 2014 using the cause of death statistics in Korea. RESULTS: There were 36,808 cases of pediatric deaths in Korea during that 10-year period, one-third (12,515 cases, 34.0%) of which were due to CCCs. In 2014, there were 1,044 cases of pediatric deaths due to CCCs (9.8 deaths per 100,000 children) in Korea. The rate of pediatric deaths due to CCCs has declined over this 10-year period. Among CCCs, malignancy was the most common cause of death overall, as well as in children and adolescents, whereas neonatal disorders were the most common cause of death in infants. Although over 1,000 children die from chronic illnesses each year, there are no hospitals or institutes in Korea that meet the minimum standards for specialized PPC. CONCLUSION: To improve the quality of life of children suffering from CCCs and to support their families who face enormous distress, children with CCCs should be able to access adequate palliative care services. Health authorities should consider supporting the establishment of PPC centers and increasing PPC accessibility in Korea.
