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.

We report a case of cerebriform intradermal nevus. a cause of cutis verticis gyrata that clinically they resembled neurofibroma and revealed histopathologic finding consistent with intradermal nevus. The patient was a 6 year-old boy, who had a 17x18cm, soft, convoluted. pigmented mass over the parietal and occipital regions. The lesion had been present since birth and had been slowly increasing in size with convolution.

Accidental aspiration of barium contrast medium during the upper gastrointestinal study can occur in patients with swallowing disorder, especially in the elderly patients. We experienced a case of respiratory failure followed by death within a few hours in a 85 year-old patient after barium aspiration.

5.The Change of Activated Coagulation Time during Cardiac Surgery.
Korean Journal of Anesthesiology 1992;25(3):503-508
Since it's introduction by Hattersley in 1966, the acivated coagulation time(ACT) is widely used as a indicator of coagulation status of a patient during cardiac surgery. There have been many studies about the pre-heparin and post-heparin(post-protamine) ACT's, but the results vary. Comparisons of baseline ACT to postprotamine ACT revealed that there were studies which showed postprotamine ACT significantly above baseline ACT, while others were opposite. So we checked baseline ACT at three different point of time: 1) before anesthetic induction; 2) after anesthetic induction; 3) after sternotomy. We also checked postheparin and postprotamine ACT, and compared it with baseline ACTs. The postprotamine ACT showed significant increase compared with the preinduction and postinduction ACT and no significant differences between preheparin ACTs. We think that hemodilution and hypothermia might have influenced on the postprotamine ACT. It seems that baseline ACT can be measured anytime before the injection of heparin. But there are many factors which can influence the measurement of the ACT. Therefore, cares must be taken in the interpretating the result of ACT, considering the factors of ACT variability and clinical observations of blood coagulability.

PURPOSE: To evaluate the radiologic characteristics of axillary lymph nodes which are found on mediolateral oblique(MLO) view of mammography and to assess their clinical significance. MATERIALS AND METHODS: We retrospectively evaluated 119 cases axillary lymph nodes on MLO view of 410 cases of mammography in 205 patients regarding the size, bilaterality, number, grade of density, presence of central lucency, calcification of lymph nodes and presence of associated parenchymal pathologic lesions in breast. RESULTS: Axillary lymph nodes on MLO view were demonstrated in 119 (29%) among 410 cases. Axillary lymph nodes(112 cases) in cases without breast parenchymal lesions or with benign breast lesions showed; unilaterality in 68 cases(61%), smaller than 1.5cm in 100 cases(89%), lower density than breast parenchyma in 99 cases(88%), presence of central lucency in 99 cases(88%) and calcification in 3 cases(2.7%). Axillary lymph nodes(7 cases)in cases with breast cancer showed small size of less than 1.5cm in 4 cases(57%), absence of central lucency in 7 cases(100%) and iso-to higher density than breast parenchyma in 7 c&ses(100%). CONCLUSION: Axillary lymph nodes noted on MLO view of mammography, more than 1.5cm in diameter, absence of central lucency and iso to higher density than breast parenchyma could be suggested as clinically significant.

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.
