BACKGROUND: Although hypochlorhydria, hypergastrinemia and antiparietal cell antibody have been well documented in the patients with hyperthyroidism, a cause of hypochlorhydria or hypergastrinemia is unknown at the present time. Therefore, in order to clarify an inhibitory mechansim of gastric acid secretion in the patients with hyperthyroidism, interrelationship among hypochlorhydria, hypergastrinemia and antiparietal cell antibody was investigated in this study. METHODS: The gastric secretory function, fasting and postprandial plasma concentrations of gastrin and titer of antiparietal cell antibody in the plasma were determined in the patients with hyperthyroidism and normal subjects. Immunoblot analysis was performed to identify the gastric membrane protein, a possible gastric antigen to antiparietal cell antibody. Using a immunocytochemical technique with electron microscopy, intracellular structure of the parietal cell reacted with antiparietal cell antibody was observed. RESULTS: The basal and pentagastrin-stimulated maximal acid output were reduced in the patients with hyperthyroidism. The fasting and postprandial plasma concentrations of gastrin were markedly elevated in the patients. The plasma gastrin concentration in the patients with the antiparietal cell antibody was higher than that of the norrnal subjects as well as the patients without the antibody not only in the fasting state but also in the postprandial state. However, the plasma gastrin concentration of the patients without the antiparietal cell antibody was elevated in the fasting state only. There was no difference in the gastrin content of the antral mucosa between the norrnal subjects and the patients. The antiparietal cell antibody was detected in 5 (38.5 %) out of 13 patients by using the indirect immunofluorescence method. Patient IgG dose-dependently inhibited rabbit gastric H (+),K (+)-ATPase activity. Among proteins of the rabbit gastric mucosa membrane, four high molecular weight proteins (91, 140, 170 and 210 K dalton) were reacted to the patient IgG. The patient IgG positive peroxidase-antiperoxidase (PAP) activity was electron microscopically detected on the intracellular cannalicular membrane of the parietal cell CONCLUSION: We conclude that hypochlorhydria and hypergastrinemia in the patients with hyperthyroidism are partially related to the antiparietal cell antibody and that the antigen to the antiparietal cell antibody may be H (+),K (+)-ATPase in the intracellular canalicular membrane of the parietal cell.

Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aorta. The stent was unable to be retrieved into the guide catheter, as it was distorted. A goose neck snare was used successfully to catch the stent in the ascending thoracic aorta and retrieved the stent externally via the arterial sheath.

Dural metastasis associated with chronic subdural hematoma is very rare in patients with malignant neoplasms; it may be difficult to distinguish malignant neoplasms from chronic subdural hematoma. Chronic subdural hematoma is usually a late manifestation of malignant tumors, which contributes to the severity of the prognosis. The scans obtained by using magnetic resonance imaging or computed tomography may be misleading when a subdural hematoma masks the underlying tumor. Herein, we report a case of a subdural hematoma with dural metastasis of unknown origin in a 45-year-old woman; however, the neoplasm was not detected until autopsy.

OBJECTIVE: It is not unusual to decompress two consecutive disc levels in treating patients with multiple radiculopathy or uncertain level diagnosis. However, the controversy over whether to use corpectomy or bisegmental diskectomy for anterior cervical fusion is still largely unsettled. The aim of this study is to define the properties of these two surgical options. PATIENTS AND METHODS: We performed a retrospective review of radiological data and clinical records only in patients whom the follow up period is longer than 12 months. Functional outcome, fusion rate, complication rate, and duration of anesthesia were analyzed in both groups. RESULTS: In total of 61 cases, corpectomy was performed in 34 and the bisegmental diskectomy in 27 patients. Mean follow-up periods were over 24 months in both groups. Anesthesia time was shorter in corpectomy patients(280 minutes vs. 300 minutes in segmental diskectomy). However, the bisegmental diskectomy group was better in achieving good clinical outcome(92.6% vs. 82%). Overall fusion rate in bisegmental diskectomy was 100%. Hardware failure rate was lower in bisegmental diskectomy group(11% vs. 18%). Revision was needed in 6% of corpectomy group. CONCLUSIONS: In conclusion, although the anesthesia time is slightly longer in bisegmental fusion, we believe the method of bisegmental diskectomy is better in accomplishing higher fusion rate and lower complication rate.

Aspergillosis refers to an infection with any species from the genus Aspergillus. Pleural aspergillosis is an uncommon disease with less than 30 cases having been reported in the literature since 1958. The etiologic factors for this aspergillosis are preexisting pulmonary tuberculosis, bronchopleural fistula, pleural drainage, and a lung resection. Surgical removal of the aspergillus-infected pleura is the main treatment for managing this disease. We have experienced two cases of pleural aspergillosis as a complication of a preexisting chronic empyema. The chest radiographs showed a pyopneumothorax with cavitation and the chest computed tomographic scans revealed a loculated pyopneumothorax with cavity formation suggesting a bronchopleural fistula. A grossly purulent fluid was extracted by thoracentesis, and Aspergillus fumigatus was grown from a fungus culture of the fluid. A decortication, wedge resection with a pleurectomy and a pleuropneumonectomy were performed. The postoperative course was satisfactory and the patients have been in good condition up to now. Pleural aspergillosis is a very rare and potentially life-threatening disease. However, good result without significant complication were obtained by treatment with systemic antifungal agents and surgical removal.

BACKGROUND: Angiogenesis is an essential component of tumor growth and metastasis, and the vascular endothelial growth factor (VEGF) is one of the most important angiogenic factors. Several solid tumors produce substantial amounts of VEGF, which stimulates proliferation and the migration of ednothelial cells, therby inducing neovasculization by a paracrine mechanism. To evaluate the prognostic roles of angiogenesis and VEGF expression in patients with non-small cell lung cancer, the relationship between VEGF expression in tumor tissues, the clinicopathologic features and the overall survival rate were analysed. METHODS: Sixty-nine resected primary non-small cell lung cancer specimens were evaluated. The pareffinembedded tumor tissues were stained by anti-VEGF polyclonal antibodies using an immunohistochemical method to assess VEGF expression. RESULTS: In Forty-one patients (59%), the VEGF antigen was expressed weakly in their tumor tissue, whereas in twenty-eight patients (41%) the VEGF antigen was expressed strongly. The median survival time of the weak VEGF expression group was 24 months, and that of the strong VEGF expression group was 19 months. The three year-survival rates were 35%, 33%, respectively. The survival difference between both groups was not statistically significnat. CONCLUSION: Although results were not statistically significant, the strong expression group tended to poorer prognosis than weak expression group.
