1.CT findings of extramedullary hematopoiesis in the thorax, liver and kidneys, in a patient with idiopathic myelofibrosis.
Journal of Korean Medical Science 2000;15(4):460-462
Extramedullary hematopoiesis occurring in multiple organs such as thorax, liver and both kidneys is an unusual condition. We report the CT findings of this condition with review of literature. The lesions consisted of intrathoracic paravertebral masses, focal intrahepatic mass and masses of both pelvocalyceal systems on CT scans.

OBJECTIVE: The goal of this study was to review the etiologies, phathophysiology, clinical presentations and to compare the results of the surgical methods of subdural empyema especially in infants. PATIENTS AND METHODS: We reviewed the clinical data of five infantile subdural empyemas experienced in our hospital from 1993 to 1998 which were all surgically treated by craniotomy or burr hole trephination. We experienced five cases of infantile subdural empyema: two males and three females. The ages ranged from 40 days to 11 months. RESULTS: The etiologies of all five cases were unproven but all five cases had meningitis before the subdural empyemas were diagnosed. The causative organism in one was streptococcus pneumoniae, and the other were unknown. Two were treated with craniotomy(one with a good outcome and the other died) and three were treated with burr hole trephination(all three had a good outcome). CONCLUSION: Subdural empyema is a rapid progressing disease and it is important to detect and treat in the early stages of disease. The choice of surgical method must be based on the stage of the disease and its location in the cranial cavity.

Ciliated hepatic foregut cyst (CHFC) is a rare benign lesion consisting of ciliated pseudostratified columnar epithelium, loose subepithelial connective tissue, a smooth muscle layer, and an outer fibrous capsule. We encountered a patient with retroperitoneal and posterior mediastinal neurilemmoma and additional CHFC mimicking metastasis. Abdominal CT examination demonstrated that the posterior mediastinal and retroperitoneal lesions were lobulated, well-defined tumors with a neural foraminal extension that were pathologically confirmed as neurilemmomas. Unenhanced CT indicated that the additional lesion was a slightly hypodense mass relative to surrounding parenchyma at the medial segment of the left lobe of the liver, and after the IV ad-ministration of contrast material, the lesion did not show enhancement.

Eosinophilic cholecystitis is a rare disease characterized by transmural leukocyte infiltration composed of more than 90% eosinophils. Eosinophilic cholecystitis is clinically indistinguishable from ordinary cholecystitis, and as a rule it leads to cholecystectomy. We report a case of idiopathic eosinophilic cholecystitis treated with steroids. A 75-year-old woman presented with a classic history of acute cholecystitis and a peripheral eosinophilia of 41.8%. There was no evidence of allergy or parasitic infestation. An abdominal ultrasonography and computed tomography (CT) scan showed an edematous, thickened gallbladder wall, but no gallstones. There was no evidence of eosinophilic infiltration in other organs. Cholecystectomy was not performed because the patient refused surgical management. However, fever, abdominal pain, and peripheral eosinophilia persisted despite antibiotic and conservative therapy. Therefore, we attempted treatment with prednisolone. A week later, the symptoms disappeared and the peripheral eosinophilia normalized.

Clostridium difficile is the most common nosocomial pathogen of the gastrointestinal tract. Pseudomembranous colitis occurs as a result of a severe inflammatory response to Clostridium difficile toxins. Pseudomembranous colitis is an increasingly frequent cause of morbidity and mortality among elderly hospitalized patients. Diarrhea is the most common manifestation. According to the literature, stools are almost never grossly bloody, and range from soft and unformed to watery or mucoid in consistency. We now report the cases of three patients with pseudomembranous colitis whose main clinical manifestation was hematochezia.

Human sparganosis is caused by the larval tapeworm of genus Spirometra. This parasite commonly invades subcutaneous tissues and muscles. However, infection in the pleural cavity is rare. A 65-year-old male patient, who had undergone surgical excision of subcutaneous masses due to a parasite infection (presumed to have been sparganosis) approximately 10 years ago, showed pleural effusion and peripheral eosinophilia. The anti-sparganum specific IgG antibody levels in the serum and pleural fluid were significantly higher than the normal control levels. Three consecutive doses of praziquantel (75 mg/kg/day) were administered for control of pleural effusion and peripheral eosinophilia. In this patient, sparganosis was suspected, and the probable cause of the infection was ingestion of raw snakes and frogs. Immunoserologic tests using ELISA can be helpful in diagnosis of pleural sparganosis and praziquantel is suggested as an alternative treatment for surgically unresectable cases.

A 43-year-old man was admitted complaining of swallowing difficulties. The esophagography revealed severe stenosis at the esophagogastric anastomotic site. Esophagography after balloon dilatation showed a transmural perforation with mediastinal leakage. The patient was treated conservatively for one week at which time the esophagography showed no further leakage at the anastomotic site and the good passage of barium. A 2-year follow-up chest computed tomography (CT) showed good patency of the esophageal lumen and the marked resorption of barium in the mediastinum.

BACKGROUND: IGF-I is an important mitogen in many types of malignancies. Tumors also express many IGF binding proteins, which modulate IGF action. The purpose of this study was to evaluaste the effect of IGF-I and IGFBP on cell proliferation in mouse lung cancer cells (3LL). METHODS: The cellular proliferation of 3LL with the treatment of growth factors was evaluated using MTT assay. Western ligand blot was performed in order to determine whether 3LL cells secrete IGFBPs and we evaluated the effect of IGFBP on cellular proliferation. RESULTS: The treatment of 3LL cells with IGF-I increased cellular proliferation in a serum free media. Western ligand blot of conditioned medium of 3LL with 125I-IGF-I demonstrated one single major band with an estimated molecular mass of 24 kDa. This band was identified as IGFBP-4 with immunoblot analysis using antisera. The addition of anti-IGFBP-4 antibody to abrogate the effect of IGFBP-4 resulted in increased cellular prolife ration suggesting that IGFBP-4 inhibits cell growth. CONCLUSION: IGF-I increases cellular proliferation, however the secreted IGFBP- 4 has an ingibitory function on cell growth in 3LL. These findings suggest that IGF-I and IGFBP are involved in the cell proliferation.

10.Treatment of Splenic Artery Aneurysm with Double Overlapping Bare Stents: Case Report.

Journal of the Korean Radiological Society 2004;51(3):291-294
The traditional treatment of splenic artery aneurysm (SAA) is generally surgery and/or transcatheter arterial embolization, but recently, the treatment of SAA using a stent graft has been reported. However, the acute angle of the celiac axis, as well as the tortuous path of the splenic artery makes the use of stent graft difficult for treatment of aneurysms. We report here a case of SAA treated with the technique of double overlapping metallic stents.
