Methods: CT ?ndings of 131 cavitary metastatic nodules in 40 patients with pathologically-proved pulmonary metastases were retrospectively analyzed. A comparison between CT signs and the pathologic types of the primary tumors was made. Results: Cavitary metastases and multiple solid nodules coexisted in all patients. Cavitary metastases presented as bubble (n=41), irregular (n=33), cystic (n=26) or small circular (n=31) cavities, with even (n=61) or uneven (n=70) thickness of the cavity wall. Of 131 cavitary nodules, diameter less than 15 mm was seen in 44, between 15–25 mm in 66, 25–40 mm in 17 and larger than 40 mm in 4 respectively. And the wall thickness of the cavity below 4 mm, between 4–15 mm and over 15 mm was respectively seen in 69, 44 and 18 metastatic nodules. Cavitary pulmonary metastases mainly occurred in patients whose primary malignancy was squamous cell carcinoma (n=13) or adenocarcinoma (n=22). Both squamous cell carcinoma and adenocarcinoma had its own CT characteristics. The occurrence of cavity bore no relationship to its site in the lung. Conclusion: Cavitary pulmonary metastases carries certain CT features and its occurrence is related to the pathologic type of the primary malignancy.展开更多

It mostly affects adults at the average age of 60 years.These polyps are able to cause abdominal pain,gastrointestinal bleeding,intestinal obstruction or intussusception.In this paper we report a case of gastric TIP with unusual presenting features. METHODS:A child with gastric IFP was described and the literature was reviewed, RESULTS:A 4-year-old girl presented with fever for 2 months,arthralgia of knees and ankles,iron defidency anemia, and hypoalbuminemia.Her stool examination was positive for occult blood.The upper gastrointestinal study demonstrated a large Iobulated mass at the upper part of gastric body.Partial gastrectomy en blocwith this 5 cm×8 cm mass was subsequently performed.Pathological examination was consistent with IFP.Following the mass excision,her fever abruptly declined and disappeared together with anemia and arthralgia.She remained asymptomatic and the abdominal ultrasonography performed at the 24-month follow-up demonstrated no recurrence of the tumor. CONCLUSION:The etiopathogenesis of IFP still remains unclear,The presence of IFP throughout the gastrointestinal tract and its variable clinical appearances make it difficult to diagnose,The inflammatory symptoms found in this patient support the hypothesis of inflammatory benign lesions of IFP.展开更多

METHODS: Eleven adult cases of congenital bronchoesophageal fistula diagnosed and treated in our hospital between May 1990 and August 2010 were reviewed. Its clinical presentations, diagnostic methods, anatomic type, treatment, and follow-up were recorded. RESULTS: Of the chief clinical presentations, nonspecific cough and sputum were found in 10 (90.9%), recurrent bouts of cough after drinking liquid food in 6 (54.6%), hemoptysis in 6 (54.6%), low fever in 4 (36.4%), and chest pain in 3 (27.3%) of the 11 cases, respectively. The duration of symptoms before diagnosis ranged 5-36.5 years. The diagnosis of congenital bronchoesophageal fistulae was established in 9 patients by barium esophagography, in 1 patient by esophagoscopy and in 1 patient by bronchoscopy, respectively. The congenital bronchoesophageal fistulae communicated with a segmental bronchus, a main bronchus, and an intermediate bronchus in 8, 2 and 1 patients, respectively.The treatment of congenital bronchoesophageal fistulae involved excision of the fistula in 10 patients or division and suturing in 1 patient. The associated lung lesion was removed in all patients. No long-term sequelae were found during the postoperative follow-up except in 1 patient with bronchial fistula who accepted reoperation before recovery. CONCLUSION: Congenital bronchoesophageal fistula is rare in adults. Its most useful diagnostic method is esophagography. It must be treated surgically as soon as the diagnosis is established.展开更多

The narratives encompassed by both productions revolve around shared Australian histories, for audiences attracted by place and what it is able to represent. Re-enactments of past events call into the present a consideration of what still remains, with both shows enabling new subjective interpretations of earlier times. The defining difference between the two, however, rests in the context of each performance, in the one case as a commodification of heritage and in the other case as the desire to produce an artistic yet popular theatrical product. Ballarat＇s, Sovereign Hill＇s light and sound show, Blood on the Southern Cross celebrates and commemorates, in mega-spectacle style, the Eureka Stockade, one of Australia＇s key historical events. Using a mechanised display of the original goldmining site of the Eureka rebellion, the performance is operated by computers with video-projection, multi-phonic sound, and moving model forms, with audiences moved around the massive site on transporters. The Piccolo Tales, a contrasting performance most notably in terms of size, unfolds the history of Kings Cross, through its setting in the miniscule iconic Piccolo Bar, in one of the tiny side streets of Sydney＇s bustling and densest suburb. This paper encompasses an investigation of how the cultural inscriptions of the two specific sites interweave with the performance styles, materials, political and social positioning of the works. Previous performance studies examining site-specificity are utilised, including the author＇s analysis of particular festival performances as ＂place-making＂ （Hayes, 2012, 2013）. Smith＇s （2009） model of ＂signposts＂ is used to consider acting within site-specific productions in a new light, whilst both performances are more completely analysed through Schneider＇s （2011） concept of incomplete pasts forming ＂cycles of memory＂.展开更多

Methods: A retrospective study was made on 259 patients with TST admitted to our department as an emergency treatment from January 1996 to June 2001. We summarized the clinical features of TST associated with CTAI. Results: Among 259 patients with thoracic spinal trauma, 112 were associated with CTAI. Traffic accident was the most common cause. The force causing upper TST was more violent than that causing the lower. Pulmonary complications were the leading cause of death in this group. Surgery could not improve neurological function for completely paraplegic patients. Conclusions: The reason that upper TST has the tendency to be associated with CTAI is its special anatomical feature. Routine ultrasonic examination can avoid misdiagnosis of latent closed abdominal injuries associated with spinal injury. The presence of potential injuries, especially CTAI, should be considered when deciding whether or not to perform surgery early.展开更多
