The use of intravacular catheterization for both diagnostic and therapeutic purposes increased the incidence of iatrogenic foreign bodies, which might cause many complications such as cardiac arrythmias, perforation of cardiac chamber or blood vessels, sepsis and thromboembolism. The authors experienced 5 cases of successful retrieval of intravascular iatrogenic foreign bodies: three cases of subclavian catheter wire and two cases of subclavian catheter. Subclavian catheter was introduced into right subclavian venous route for hyperalimentation or central venous pressure monitoring. The foreign bodies were located in superior vena cava and inferior vena in four cases and in left main pulmonary artery in the other case. We have successufully removed the foreign bodies by interventional procedures. The loop-snare technique is a safe and effective method for retrieval of iatrogenic foreign bodies in great vessels.

Pseudo-Bartter syndrome is a rare medical disease of the kidney characterized by normal blood pressure, hypokalemic metabolic alkalosis, hyperreninemia and hyperaldosteronism with drug history of diuretics. We report US, CT and MRI findings of a patient with clinically proved pseudo-Bartter syndrome. The patient was a 37-year-old woman with a history of long term ingestion of the diuretics(furosemide) for 20 years. Renal US revealed hyperechoic renal medulla at both kidneys. The resistive index(RI), calculated from the duplex doppler waveform is 0.61. Unenhanced CT revealed faint high attenuation along the medulla. Tl-weighted MRI revealed indistinct corticomedullary differentiation.

Chest CT is the most useful modality in the diagnosis of primary lung cancer, particularly in patients with recurrent pneumonia which are resistant to antibiotic therapy and in high risk age groups for cancer, The purpose of this examination is to assess the usefulness of CT in pneumonia types of lung cancer. The authors retrospectively analyzed 15 histologically proven cases of pneumonic type lung cancer, which had no evidence of primary lung mass, mediastinal lymphadenopathy or other metastatic lesion on piain chest radiography. On CT scan, a primary lung mass was identified in 13 patients(87%, bronchial obstruction was identified in 12 patients(80%), and metastatic foci was found in the bone(one patient), liver(one patient), and spleen(one patients). In Conclusion, CT scan is a useful method to detect the mediastinal lymphadenopathy or pulmonary mass and also should be the initial radiolographic procedure for diagnosis of lung cancer in patients with recurrent pneumonia on simple chest radiography.

Optic perineuritis is characterized by optic disc swelling with normal visual acuity, pupillary responses and intracranial pressures, and normal visual fields except for an enlarged blind spot that may be confused with papilledema caused by brain tumor or pseudotumor cerebri. It is a rare manifestation of neurosyphilis, and it is thought to represent an extension of basal meningeal inflammation to the optic nerve sheaths. Serum VDRL tests are negative in a significant proportion of patients with late syphilis, particularly in those with neurosyphilis(seronegative syphilis). We present a case of optic perineuritis associated with seronegative neurosyphilis.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.

A case of xanthogranulomatous oophoritis is presented in a patient who had a 3-month history of intrapelvic mass protruding into the vagina. The sonographic findings are a well defined mass shadowing lower echogenicity than the echo of the uterus at the posteosuperior aspect of the uterus. The CT findings are an enhancing solid mass with central necrosis containing a multiseptated cystic component.

The magnetic resonance images (MRI) of 30 patients with surgically or biochemically confirmed pituitary adenomas (20 macroadenomas, 10 microadenomas) were retrospectively evaluated. Ten patients had hyperprolactinemia, another eight had acromegaly, another eight had nonfunctioning adenoma and four had Cashing disease. The examination were performed at a 1.5-T superconducting MR system using a multisection spin-echo technique with 3mm-thick sections and a 256×224 matrix. TI weighted sagittal and coronal images were obtained before and within 30 minutes after the administration of Gd-DTPA (0.1mmol/kg). Analysis of the MRI was focused on the signal intensity and enhamcement patterns of the pituitary adenoma before and after Gd-DTPA administration. Compared with endocrinologic diagnosis, macroadenoma showed heterogeneous enhacement in 55%, rim enhancement in 35% and homogeneous enhancement in 10%, Conclusively, the enhancement patterns of the pituitary adenoma did not correlate with the subtypes made according to hormone production.
