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.

The hemodynamic interactions of lidocaine and diltiazem during halothane anesthesia were studied using eight mongrel dogs. The animals were anesthetized with inhalation of 1.0 MAC of halothane(GroupH) continuously throughout the experiment. 30 minutes after the inhalated and end-tidal halothane concentration reached equilibrium, 0.2 mg/kg of diltiazem was given intravenously over 2.0 min. From that point 8 ug/kg/min of diltiazem was continuously infused (group HD). Then a small dose of lidocaine(group HD1; iv bolus 1.5 mg/kg over l min, followed by continuous iv infusion at the rate of O.l mg/kg/min for 30 min) and a large dose of lidocaine (group HDI; iv bolus 1.0 mg/kg over I min, followed by continuous iv infusion at the rate of 0.3 mg/kg/min for 30 min) were administered serially. In group HD, PR interval increased significantly(22.2%) and coronary perfusion pressure decreased significantly(l9.3%), compared with group H. Compared with group H, significant increase in PR interval(44.4%), and decreases in diastolic arterial blood pressure(28%), mean arterial blood pressure(20.1%) and rate pressure product(35.2%) occured in group HD1. In group HDL, a significant decrease in heart rate(20.7%) and coronary perfusion pressure(33.0%) also occured, compared with group H. No significant changes in oxygen transport and consumption existed among groups. The most significant result of the injection of lidocaine diltiazem during halothane anesthesia in dogs was increase in PR interval. Even in high doses of lidocaine, only slight hemody- namic depression resulted and no significant changes in tissue oxygenation occurred. Therefore, the combined administration of diltiazem and lidocaine in clinical doses during halothane anes- thesia in dogs is a relatively safe administrative method.

Dental restorative materials must have the physical properties to withstand wear and corrosion. Base metal alloys possess better mechanical properties and lower price than the gold alloys. For these reason such alloys have largely replaced the precious metal alloys. One aspect to consider is the release of metal substances to oral environment. The release of elements from dental alloys is a continuing concern because the elements may have the potentially harmful biological effects on local tissue. The purpose of this study was to minimize metal release on the nonprecious metal surfaces by ion bea assisted deposition(IBAD) of titanium nitride (TiN). Ni-Cr-Be alloys with and without TiN coatings were secured in an wear test machine opposing ruby ball to determine their relative resistance to wear with 100m, 200m, 300m and 400m sliding distance. And the corrosion behavior of the Ni-Cr-Be alloys with and without TiN coating and 3 dental noble alloys have been studied. Potentiodynamic curves were used to analyse the corrosion characteristics of the alloys. The measurement of the released Ni and Ci ions was conducted by analysis of the electrolyte solution with atomic absorption spectroscopy. The results were as follows : 1. The critical sliding distance that wore down TiN coating of 2.5micrometer thickness in this study condition was 300m. 2. Ion beam assisted deposition of TiN showed a good surface modification with respect to the properties of wear and corrosion resistance. 3. X-ray diffraction showed that the strongest peak of TiN(111) in the coatings. 4. The release of Ni and Cr ions from alloys measured by means of atomic absorption spectroscopy was reduced by ion beam assisted deposition of TiN.

An analysis was performed on 270 open heart patients having post-operative respiratory care in the respiratory intensive care unit of Seoul National University Hospital during 1987. The analysis was done according to disease prevalence, sex, age, pump time, duration of mechanical ventilation and mortality rate. 1) The number of cases of acquired heart disease was more than that of congenital heart disease. 2) The most prevalent disease was ventricular septal defect combined with other diseases. 3) The mean age of the total patients was 36.5. The oldest age group was patients who received CABG and the youngest had a ventricular septal defect combined with other diseases. 4) The mean pump time was 93,4 minutes and it was longer in the patients with acquired heart disease than the patients with congenital heart disease. 5) The mean duration of mechanical ventilation was 68.5 hours and it was longer in the patients with acquired heart disease than those with congenital heart disease by about two times. 6) The overall mortality rate was 3.0% which was higher rate than that of the 3rd and 4th reports, and it was a higher in the patients with acquired heart disease than with congenital heart disease. The most prevalent cause of death was low cardiac output syndrome. 7) The length of mechanical ventilation time and death rate were closely related with pump time.

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.

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.
