A 59-year-old man was admitted to our hospital, complaining of fever and left lumbago. He was diagnosed with primary left iliopsoas abscess and treated with draining the abscess percutaneously and antibiotics. Chest x-rays taken on admission showed multiple round nodules in both lung fields. CT scans of the chest revealed a wedgeshaped lesion abutting the pleura in the left lower lung field and multiple nodules of various sizes in both peripheral lung fields. Some nodules had cavities with thin walls and feeding vessels. Follow-up CT scans to the chest demonstrated that some old nodules had vanished and new nodules developed in both lung fields. The diagnosis of septic pulmonary embolism secondary to iliopsoas abscess was established, because organized pneumonia was detected in the transbronchial lung biopsy specimens and the cultures of the pus from the abscess and the sputum on admission showed Enterococcus faecium.

OBJECTIVE: This study examined the association between sleep habits and problems and Internet addiction in adolescents. METHODS: Junior high school students from a local town in Japan (n=853; male/female, 425/428) were the subjects of this study, and were assessed for severity of Internet addiction and sleep habits and problems using the self-reported version of the Young’s Internet Addiction Test (IAT) and Child and Adolescent Sleep Checklist (CASC). RESULTS: The wake time on weekdays was not significantly different among the three groups; addicted, possibly-addicted, and non-addicted. In the addicted group, the total night sleep time was significantly shorter, and the bedtime was significantly delayed on both weekdays and weekends compared with those in the possibly-addicted and non-addicted groups. The wake time of the addicted group was significantly later than that of the other groups. The total scores of sleep problems measured by the CASC were significantly higher in the addicted and possibly-addicted groups than in the non-addicted group. CONCLUSION: Internet addiction is strongly associated with sleep habits and problems in adolescents. These findings suggest that internet addiction should be considered while examining adolescent lifestyle.
