Herpes zoster (HZ) has been reported in immunocompetent children who received the varicella vaccine. In vaccinated children, HZ can be caused by vaccine-strain or by wild-type varicella-zoster virus (VZV). Like wild-type VZV, varicella vaccine virus can establish latency and reactivate as HZ. We report two cases of HZ in otherwise healthy 16- and 14-month-old boys who received varicella vaccine at 12 months of age. They presented with a vesicular rash on their upper extremities three to four months after varicella vaccination. In one case, a swab was obtained by abrading skin vesicles and VZV was detected in skin specimens by polymerase chain reaction. The VZV open-reading frame 62 was sequenced and single nucleotide polymorphism analysis confirmed that the virus from skin specimen was vaccinestrain. This is the first HZ case following varicella vaccination confirmed to be caused by vaccine-strain VZV in the immunocompetent children in Korea. Pediatricians should be aware of the potential for varicella vaccine virus reactivation in vaccinated young children.

MRI plays a crucial role in bone marrow (BM) assessment, and has very high sensitivity in diagnosing marrow disorders. However, for radiologists who may not frequently encounter pediatric imaging, distinguishing pathologic BM lesion from normal BM can be challenging.Conditions involving the BM in pediatric patients, such as leukemia and metastatic neuroblastoma, often manifest with diverse musculoskeletal symptoms and may be diagnosed using musculoskeletal MRI examinations. Accurate interpretation of pediatric MRI requires not only an understanding of the normal composition of BM but also an awareness of agerelated developmental changes in the marrow and familiarity with conditions that commonly involve pediatric BM. We aim to describe the composition of normal BM and outline the normal and abnormal MRI findings in pediatric BM. Additionally, we aim to present clinical cases of malignant BM disorders including leukemia, neuroblastoma metastasis, and other malignant BM disorders.

BACKGROUND: Life expectancy is ever increasing due to medical advancements, but cancer death rate is also increased. Quality of life is an important issue in cancer patients. Despite developments of early diagnosis and treatments for cancer, the medical costs is increasing due to exfended sarvival against cancer and the absolute numbers of terminal cancer patients. We assessed the medical costs and quality of life in terminal cancer patients by the types of medical facilities, which would contribute to effective management. METHOD: A total 159 patients(males 70, females 89) with terminal cancer patients who were treated and died in various types of medical facilities(home hospice, charity hospital hospice unit, university hospital hospice unit, university hospital non-hospice unit) between November 1, 1997 and January 31, 1999 were included in the study. After the confirmation that the demographic factors correlated with factors of quality of life, the differences in the medical costs and quality of life(pain, depression, ADLs, family APGAR score) during the last 1 week of life in the various types of medical facilities analyzed by multi-way ANOVA with interaction of the significant demographic factors. RESULTS: The mean cost of types of medical facilities during the last week of patients as 65332.5 won in charity hospital hospice unit, 105165.5 won in home hospice, 702083.4 won in university hospital hospice unit, and 1037358.6 won in university hospital non-hospice unit. The difference between free hospital hospice unit and home hospice in medical costs as not statistically significant, but the difference among charity hospital hospice unit and home hospice, university hospital hospice unit, and university hospital non-hospice unit as significant (p<0.001). The demographical factors of quality of life in terms of pain, depression, ADLs, and family APGAR score were compared among various facilities. The ADL score of home hospice was 8.2 +/- 3.3, which was lower than free hospital hospice unit and university hospital hospice unit(p<0.05). The mean pain scor of home hospice as 1.7+/-1.7 and that of university hospital hospice as 1.2+/-1.2, and pain scores of home hospice were lower than free hospital hospice unit, and pain scores of university hospital hospice were lower than free hospital hospice unit and university hospital non-hospice unit(p<0.05). In depression's categorial scale of home hospice the score was 4.8+/-1.3, which was higher than those of free hospital hospice unit and university hospital non-hospice unit(p<0.05), signifying less depression. The family APGAR score was statistically insignificant among various types of medical facilities. CONCLUSION: The cost of hospice care is less than the non-hospice care. We found that the patients of home hospice experienced less pain and depression even with low ADLs, and increased the quality of life in both psychological and physical aspects.
