Objectives: Endoscopic variceal ligation is well established metbod of treatment for esophageal varices whereas for gastric varices there has not been any systematic report of its use as a method of treatment. To evaluated its possible clinical application, the band ligation(banding) and the method of band ligation in conjuction with submucosal ethanolamine injection(banding with sclero) were tested on canine stomach, and results were assessed.

This report describes clinical cases of a palato-gingival groove on a maxillary lateral incisor with associated localized periodontal disease and pulp necrosis. The tooth of the first case was extracted because of severe bone destruction. The palato-gingival groove of the second case was eliminated using a round bur, and the resulting defect was filled with synthetic graft and covered by an absorbable membrane. Both diagnosis and treatment of palato-gingival groove were very difficult and usually extraction of the involved tooth is the treatment of choice, but combined endodontic-periodontic treatment allowed the tooth to be saved.

PURPOSE: To evaluate the fluorodeoxyglucose positron emission tomography (FDG-PET) features of progressive massive fibrosis (PMF) in patients with pneumoconiosis. MATERIALS AND METHODS: FDG-PET and chest CT scans were performed in 11 patients with pneumoconiosis and PMF on chest radiographs. We evaluated the size, location, maximum, and mean of the standardized uptake value (SUV) for the PMF. A fine needle aspiration biopsy was performed in patients with a mean SUV of > 2.5 to exclude lung malignancies or pulmonary tuberculosis. A Pearson's correlation was performed to determine if a correlation exists if between the sizes and the mean SUV of the PMF. RESULTS: A total of 19 masses from 11 patients were located in the upper lobes (bilateral in eight and right in three). The sizes of the lesions ranged from 1.3 to 6.4 cm (mean = 3.6 cm). The maximum SUV was 0.5 to 8.1 (mean = 3.8) and the mean SUV was 0.4 to 5.9 cm (mean = 2.9 cm). Lung malignancies or tuberculosis were not identified in the 12 lesions (63%) with a mean SUV of >2.5. The sizes of the PMF did not correlate well with the mean SUV (r = 0.225). CONCLUSION: FDG-PET scans can show PMFs as regions of increased metabolic activity (mean SUV, 2.9) without evidence of lung cancer or pulmonary tuberculosis. No correlation between the sizes of PMF and the mean SUV was found.

Carcinosarcoma is a rare malignant neoplasm consisting of both epithelial and nonepithelial components, that is, carcinoma and sarcoma in the same tumor. Since Queckenstedt reported the case of carcinosarcoma of the stomach in 1904, only 30 cases have been reported. We present a case of carcinosarcoma and adenocarcinoma of the stomach in 63-year-old man with the review of the literature.

Streptococcus constellatus (S. constellatus) is a commensal microorganism belonging to the "Streptococcus milleri" group, but may cause infections in different locations in immunocompromised patients. The infection of S. constellatus has high mortality and morbidity due to its tendency to cause abscesses in infected patients, which require immediate surgical drainage for effective treatment. We report on a 72-year-old woman with end stage renal disease, who suffered from dyspnea and general weakness that had developed over 7 days. Chest CT showed loculated pleural effusion. S. constellatus was cultured from exudative pleural effusions and confirmed by an analysis of 16S rRNA sequence. The patient was treated with drainage of pleural effusion and piperacillin/tazobactam for 5 weeks.

Esophageal perforation is a rare disease, which require emergent diagnosis and therapeutic procedure. In this paper, we present one case of esophageal perforation by traction of toothbrush which was swallowed during pharyngeal irritation. After the toothbrush was inserted to stomach by gastroscope, gastrostomy was performed for removal of toothbrush and the esophageal perforation was repaired by operation.

Intracavitary metastasis is an uncommon secondary cardiac malignancy and metastasis to the right atrium and ventricle is even less common. Prior reports have demonstrated an association of this disease entity with sudden death. We report a recent experience of intracavitary cardiac metastasis of a primary hepatoma in a 24-year-old woman who presented with a exertional dyspnea and a syncopal episode.

Kissing aneurysms are the rare type of multiple aneurysms. They are adjacent aneurysms of different origin arteries in the same region, which require great care in diagnosis and treatment. We report a case of kissing aneurysms at the anterior communicating artery (AcomA) which were treated by endovascular coil embolization.

PURPOSE: To understand the normal endosonographic anatomy of the perianal spaces, and to evaluate the diagnostic efficacy and limitation of endorectal sonography(EUS), correlative study with MRI, cadaveric sectional image and cadaveric MRI were performed. MATERIALS AND METHODS: EUS images of the normal 6 perianal spaces (pelvirectal, ischiorectal, intersphincteric, subcutaneous, central, submucous space) which were bounded by internal and external anal sphincters, rectal wall and levator ani muscle were correlated with MRI in 10 normal persons, cadaveric sectional images and cadaveric MRI in 2 cadavers. RESULTS: Pelvirectal space located superior to levator ani muscle could be demonstrable only on anterior wall scan but could not be visualized on lateral or posterior wall scan on EUS. Five perianal spaces located inferior to levator ani muscle were well seen on anterior, lateral, and posterior wall EUS. MRI was superior to EUS in the evaluation of pelvirectal and ischiorectal spaces but equal or inferior to EUS in the evaluation of intersphincteric, subcutaneous, central and submucous spaces. CONCLUSION: EUS was valuable in the evaluation of perianal spaces inferior to levator ani muscle but was limited in the evaluation of perianal spaces superior to levator ani muscle.

PURPOSE: To determine the presence of cruciate ligament tears following avulsion injuries involving the ACL and PCL, and to correlate the findings with those of surgery. MATERIALS AND METHODS: Between March 1997 and May 2002, avulsion injury involving the ACL or PCL was diagnosed in 19 patients. Ten of these [8 males and 2 females aged 10-51 (avergae, 27.7) years] were included in this study. We assessed the presence of cruciate ligament tears at MR imaging, correlating the findings with those of surgery. Associated intra-articular injuries, treatment methods and follow-up results were also evaluated. RESULTS: Among Seven patients with ACL avulsion injury, this was assessed at MR imaging as complete tear (n=1), partial tear (n=5), or intact (n=1), while all MR images of PCL avulsion injury (n=3) showed that this was partial tear. All imaging findings corresponded with the surgical findings. In four patients there was associated knee injury involving, respectively, tears of the medial meniscus, lateral meniscus, PCL and MCL, and popliteal ligament. CONCLUSION: Our findings showed that with one exception, patients with avulsion injury of the ACL or PCL had suffered either a partial or complete tear. MR imaging may be useful in the diagnosis of tears of the cruciate ligament which have not been noticed at surgery or arthroscopy in avulsion injuries involving the ACL and PCL.
