Neuroblastoma stage IV-S patients have frequent spontaneous remission and high survival rate. Many investigators have recommended minimal or no therapeutic intervention ; however, some patient do experience progressive disease and ultimately die of neuroblastoma. We experienced a case of stage IVS neuroblastoma with N-myc amplification and coagulopathy. This patient has treated with combination chemotherapy and radiation therapy, then remained disease free for 1 year on the follow up till March, 1997.

BACKGROUND: To compare the diagnostic usefulness of dobutamine stress echocardiography(DSE) and 99mTc-methoxyisobutyl isonitrile SPECT (MIBI SPECT), two studies were performed simultaneously. METHOD: Fifty-six consecutive patients undergoing coronary angiogram and MIBI SPECT for clinical indications without clincal evidence of myocardial infarction were studied prospectively. During the DSE, MIBI was injected at peak stress, and post-stress images of MIBI SPECT were required on hour later. Both echocardiographic and MIBI SPECT images were visually analysed in a blind fashion. RESULTS: On the basis of coronary angiographic findings, the sensitivites of the DSE and MIBI SPECT (n=36) were 89% and 86%, respectively. The specificities of those (n=20) were 90% and 85%, respectively. Among 33 patients without resting perfusion defect on MIBI SPECT, resting regional wall motion abnormalities on DSE were found in only one patient, whereas, resting perfusion defect on MIBI SPECT were found in 9 patients among 41 patients without resting regional wall motion abnormalities on DSE. Among 17 patients who had resting perfusion defects with partial reversibility on MIBI SPECT, resting wall motion abnormalities were present in 11 patients and five of them showed improvement in the regional wall motion during low dose dobutamine infusion. CONCLUSION: Both dobutamine stress echocardiography and MIBI SPECT are useful methods in the detection of the coronary artery disease, however, MIBI SPECT seems to overestimate the regional ischemic myocardium with contractile reserve that can hardly be evaluated with MIBI SPECT.

DNA pyrosequencing, one of the advanced methods for DNA sequencing, has been employed for phylogenetic analysis of bacterial communities using the conserved 16S rRNA gene. We performed a pilot study on a mother-neonate pair utilizing the DNA pyrosequencing assays to investigate the diversity of microbial communities in maternal amniotic fluid (AF), vagina, and rectum and newborn gastric fluid (GF) and stool. Phylum level analysis revealed that bacterial community was dominated by Firmicutes (63.2%) in maternal feces, and Actinobacteria (84.9%) in maternal vaginal swab. The bacterial communities in both the AF and GF were dominated by Proteobacteria (67.8%). Interestingly, the bacterial community in the newborn's meconium was quite similar to that in the AF. However, the composition of the bacterial community in newborn's feces was different on day 14 and dominated by Firmicutes (91.1%). Genus-level analysis revealed that the bacterial community in maternal feces was dominated by Anaerococcus (19.5%) and Prevotella (18.7%), whereas that in the maternal vaginal swab was dominated by Atopobium (83.6%). The bacterial communities in both the AF and GF were dominated by Sphingomonas (38.5%). The bacterial community in the newborn's meconium was quite similar to that in the AF, which was dominated by Sphingomonas (45.2%). However, the composition of bacterial community in the newborn's feces on day 14 was relatively different. Future studies with a large number of infants are needed to determine the factors involved in the changing profile of newborn's fecal bacterial communities.
