PURPOSE: To draw attention to the radiological findings of a benign variant of cerebral astrocytoma in a young patient. MATERIALS AND METHODS: A 24-year-old man with generalized tonic-clonic seizure of 7 years' duration and normal neurological examination was examined with plain skull series, brain CT and MRI, and cerebral angiography. MR imaging was performed with a 0.5 Tesla Toshiba MRT-50A scanner (TIWI, PDWI, T2WI, 0.1 mmol/kg of Gd- DTPA, SE). RESULTS: 1 ) Plain skull series: A radiolucent lesion with a partial radiopaque rim of about 2.5 x 3 cm size in the right anterior parietal bone.2) B rain CT scan: A cystic mass in the right frontoparietal cortex of midconvexity with pressure erosion on the adjacent skull and partial enhancement at outer and anterior portion.3) Brain MRI:A hypointense mass containing a small, intensely enhancing isointensity anterolaterally on Tl-weighted images, which was hyperintense with better delineation of bulging cortical-based appearance on T2-weithted images. No peritumoral edema.4) Cerebral anglography: An avascular mass. CONCLUSION: The diagnosis of pleomorphic xanthoastrocytoma(PXA) should be entertained in patients in whom a superticially placed enhancing intracerebral tumor containing cystic portion that seems to be in contact with the meninges develops during juvenile years.

In the whole arm type of brachial plexus injury, the nerve grafting method give the best result. As it is impossible, however to operate the preganglionic whole arm type by interfascicular nerve graft, the treatment of this type of injury is difficult. In this lesion, neurotization may be the only useful method. To evaluate it's efficacy, 38 cases of multiple neurotization have been reviewed. The follow up period was on average 45 months(24 months to 76 months). The results are as follows: 1. Motor or sensory improvement of good or better results was observed in 27 nerves(29%) and that of better-than-fair results in 54 nerves(57%). 2. The best results were obtained in patients less than thirty year old and in the patients where the operation was performed within the first six months after injury(19 cases, 42%). 3. The use of spinal accessory, phrenic, intercostal and supraclavicular nerves, as a source of neurotization produced similar results. Phrenic nerve neurotization was performed without any significant respiratory difficulty. 4. The results of neurotization were analysed by Kim's method. Functional recovery of the upper extremity showed relatively poor results. 5. Out of the 25 patients who had developed a painful syndrome before neurotization, 19 cases(60%) showed improvement of the symptom. Multiple neurotization in preganglionic whole arm type of brachial plexus injury is of a little value in improving upper extremity function. Nerve neurotization can not always make a paralysed upper limb useful, because it is impossible to control the digits and intrinsic muscles in the hand and to restorate fine sensation by it. Nevertheless, functional recovery of the paralyzed upper limb, compared with no previous muscle contraction, encourages patients who have suffered serious brachial plexus injuries to start an active their life again.

A 56 year-old female presented with dysphagia 8 weeks ago and newly developed dysphonia 2 weeks ago. The radiology study and swallowing difficulty evaluation study revealed the esophagus and the posterior wall of the laryngopharynx to be severely compressed by the mass of the anterior 4th and 5th vertebral body of cervical spine. En bloc excisional biopsy of the bony mass was performed, which completely resolved the clinical symptoms. We report a rare case of osteochondroma occurring at the anterior portion of cervical spine leading to dysphasia and dysphonia with a review of relevant literature.

The cardiac performance is regulated by the intergration of preload, afterload, contractility (inotropism), heart rate and synergy of ventricular contraction, which are the major determinants that govern the stroke volume and cardiac output. Valvular heart disease may be considered to impose two different types of stress on the cardiac chamber proximal to the lesion. There are either pressure overload(increased after load) or volume overload(increased preload). The compensatory mechanism of the pressure overload and volume overload offer to hypertrophy and dilatation of the chamber. Hypertrophy, increased muscle mass, calls upon the development of greater systolic force. Dilatation, overfilled chamber volume enables increased strength and extent of shortening by Frank Starling's mechanism. In these view, we shall discuss the hemodynamic parameters; cardiac output, stroke volume, ventricular end-diastolic pressure, and the rate of ventricular pressure rise(peak dp/dt), mitral valve gradient and pulmonary circulation. The authors had an opportunity to study 40 cases of mitral valvular heart disease which were accepted during the left ventricular angiography at the cardiac catheterization room and at the fields of operative findings during the period Jan. 1977, throught Sept. 1980, at the Department of Internal Medicine, National Medical Center. The following conclusions were drawn: 1) Cardiac index was 2.65 L/min/m2in average, among 18 cases with mitral stenosis and 2.54 L/min/m2 in average, among 15 cases with mitral valve area of less than 1.0 cm2. Cardiac index was 2.58 L/min/m2in average, among 19 cases with mitral stenoinsufficiency and 3.43 L/min/m2 in average, among 3 cases with pure mitral insufficiency. 2) The mean right ventricular end-diastolic pressure elevated more than 0-8 mmHg were found in 12 cases with mitral stenosis out of 18 cases and mean miral valve area was 0.8m2. The mean left ventricular end-diastolic pressure was also elevated more than 0-12 mmHg in 6 cases out of 12 cases with mitral stenosis in addition to right ventricular failure. These 12 cases of mitral stenosis had cardiac function more than class III clinically. 3) 15 cases with mitral valve area, less than 1.0cm2 demonstrated left ventricular diastolic filling pressure gradient (MVG) of 17.3mmHg in average, the pulmonary vascular resistance of 568 dyndsecd cm(-5) in average, and the right ventricular peak systolic pressure of 72mmHg in average respectively. In all instances, the right ventricular end-diastolic pressure was 11.2mmHg in average and right ventricular peak dp/dt was 571mmHg in average. 4) Among 22 cases with mitral insufficiency, and/or mitral stenoinsufficiency 16 cases showed mean left ventricular end-diastolic pressure elevated more than 0-12mmHg. 10 cases out of these 16 cases disclosed also right ventricular end-diastolic pressure elevated more than 0-8 mmHg. These 16cases of mitral insufficiency and/or mitral stenoinsufficiency had cardiac function more than class III clinically. 5) 16 cases with mitral insufficiency and/or mitral stenoinsufficiency who had mean left ventricular end-diastolic pressure more than 0-12 mmHg showed pulmonary vascular resistance, 358 dyndsecd cm(-5) in average, systemic vascular resistance, 1621 dyne/sec/cm5 in average and left ventricular peak dp/dt, 768-2102mmHg/sec in range. 6) Pulmonary hypertension elevated more than 50mmHg of pulmonary arterial systolic pressure was found in 14 cases out of 18 case with mitral stenosis and in 10 cases out of 22 cases with mitral stenoinsufficiency and/or mitral insufficiency. Pulmonary vascular resistance, however, was markedly variable.

To estimate the prevalence of hypertension among the aged in urban area, the blood pressure was examined on the subjects of 565 men and 762 women of 65 years old and older among the residents of Nam-Ku and Soosung-Ku in Taegu between January and December, 1986. The mean systolic blood pressure was 136.0±25.01 mmHg in male and 133.0±24.56 mmHg in female. The mean diastolic blood pressure was 83.7±14.41 mmHg in male and 82.4±14.43mmHg in female. There was no significant differences between male and female in both mean systolic and diastolic blood pressure. According to WHO category, the prevalence of pure systolic hypertension (≥169/≤95 mmHg) was 7.8% in male and 6.8% in female. The prevalence of pure diastolic hypertension (≥160/≤95 mmHg) was 6.0% in male and 3.9% in female. The prevalence of both systolic and diastolic hypertension (≥160/≤95 mmHg) was 13.5% in male and 12.9% in female. According to Joint National Committee category, the percentage of normal blood pressure (/<90 mmHg) was 46.7% in male and 50.8% in female. The prevalence of mild hypertension (/90=104 mmHg) was 34.5% in male and 34.6% in female. The prevalence of moderate hypertension (/105=114 mmHg) was 5.1% in male and 2.5% in female. The prevalence of severe hypertension (/≥115 mmHg) was 2.3% in male and 2.5% in female. The prevalence of borderline isolated systolic hypertension (140-159/<90 mmHg) was 9.0% in male and 6.6% in female. The prevalence of isolated systolic hypertension (≥160/<90 mmHg) was 2.3% in male and 2.5% in female.

The drinking water in apartment is stored in reservoir tank and thereafter supplied each household. In case the drinking water in stored too long or insanitary, tap water might change in quality. This study was carried out to evaluate the physic-chemical and microbiological conditions of 36 samples of tap water of apartments compared to 18 samples of tap water of independence houses in Taegu City from May to October, 1987. Main findings are summarized as follows: PH values were within normal range in all samples. Samples less than 0.2ppm in residual chlorine accounted for 16.7% in the apartment and 5.6% in the independence house. Nitrite nitrogen was detected 2.8% of apartment samples only. Among the total of 54 samples, 11.1% of the apartment and independence samples were over the normal value in standard plate count. Samples more than 1.8 of most probable number (MPN) accounted for 27.8% in the apartment and 33.3% in the independence house. In result of test for residual chlorine, nitrite nitrogen, standard plate count, and MPN, the proportion of the samples revealed inappropriate in respect of drinking water standards. In case of all sorts of tests was 2.7% in apartment and nothing in independence houses, in case of 3 sorts of tests was 2.7% in apartment and 5.6% in independence houses, in case of 2 sorts of tests was 8.3% in apartment and 5.6% in independence houses, and in case of only 1 test was 25.0% in apartment and 22.2% in independence houses. Correlation between residual chorine and standard plate count, and between standard plate count and MPN were observed. It was found that the more years since construction of apartment were, the worse tap water was in quality.
