METHODS:After a systematic search of Pubmed,Medscape and MDconsult,we reviewed and retrieved literature regarding gastric lymphoma. RESULTS:Primary gastric lymphoma is rare however,the incidence of this malignancy is increasing.Chronic gastritis secondary to Helicobacter pylori (H pylori) infection has been considered a major predisposing factor for MALT lymphoma. Immune histochemical marker studies and molecular biology utilizing polymerase chain reaction have facilitated appropriate diagnosis and abolished the need for diagnostic surgical resection.Advances in imaging techniques including Magnetic Resonance Imaging (MRI) and Endoscopic Ultrasonography (EUS) have helped evaluation of tumor extension and invasion. The clinical course and prognosis of this disease is dependent on histopathological sub-type and stage at the time of diagnosis.Controversy remains regarding the best treatment for early stages of this disease.Chemotherapy,surgery and combination have been studied and shared almost comparable results with survival rate of 70-90%.However,chemotherapy possesses the advantage of preserving gastric anatomy. Radiotherapy alone has been tried and showed good results. Stage IIIE,IVE disease treatment is solely by chemotherapy and surgical resection has been a remote consideration. CONCLUSION:We conclude that methods of diagnosis and staging of the primary gastric lymphoma have dramatically improved.The modalities of treatment are many and probably chemotherapy is superior because of high success rate, preservation of stomach and tolerable complications.展开更多

They all had operations and the pathological exami-nation confirming the diagnosis. The clinical features of diabetes insipidus and extraocular nerve palsy were presented. In two cases, the original tumors were bronchioloalveolar carcinoma; in the other one, the original tumor was unknown. All three cases had poor outcome. These cases illustrate the fact that a pituitary metastasis can closely mimic a pituitary benign tumor, such as pituitary adenoma. Especially in the presence of suggestive symptoms such as diabetes insipidus and/or cranical nerve paralysis, the possibility of metastatic disease in the differential diagnosis of a pituitary mass should always be considered.展开更多

Methods: A total of 62 consecutive cases (58 men, 4 women) from January 1999 to December 2001 with IOFBs following penetrating eye injuries were retrospectively studied. The ages ranged from 8 to 46 years (mean 23 years). Sixty patients (63 eyes) underwent pars plana vitreotomy and 1 patient underwent external magnet extraction. The follow up ranged from 3 to 36 months (mean 12.5 months). Results: Ten eyes developed endophthalmitis, among which 7 ( 10.94 %) were diagnosed preoperatively. The most frequently cultured organism was Staphylococcus epidermis ( 44.44 %, 4/9). Postoperatively, retinal detachment due to vitreoretinal proliferation occurred in 5 patients with endophthalmitis and in 9 patients without endophthalmitis. All the retinal detachments were reattached with additional vitreoretinal surgery. Two eyes with endophthalmitis and two without endophthalmitis were eviscerated. Conclusions: Post traumatic endophthalmitis with intraocular foreign bodies (IOFBs) deserves great attention because of its high incidence and poor prognosis. Vitrectomy is suggested for the treatment of IOFBs and its complications, and it should be performed as soon as possible. Routine intravenous administration of antibiotics combined with periocular injection and topical antibiotics postoperatively are recommended.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
