Early and longterm prognosis depended on the extents of acute myocardial infarction and residual myocardial function. Many clinical methods have been evaluated to determine their ability to estimate the size of myocardial infarcts. But because of many disadvantages simplified QRS scoring system, used with standard 12-lead EKG, was developed, which is noninvasive, inexpensive and easily releatible. Therefore, the correlation between QRS and peak CK,killip classification were evaluated in 55 patients with initial acute myocardial infarction at the Chung-Ang University, Yong-San and Pil-Dong Hospital during the period from January 1983 to December, 1986. The results were as follows : 1) The average QRS score of the anterior wall infarction is 7.1 and that of the inferior wall infarction is 4.5 and there is a statistical significance(p<0.01). 2) In the acute myocardial infarction, the correlation coefficeient between the QRS score and the killip classification is 0.66(p<0.05). 3) In the acute myocardial infarction, the average QRS score is 6.3 and the correlation coefficient between the leak CK and the QRS score is 0.52(p<0.05). 4) In the anterior wall infarction, the average QRS score is 7.1 and the correlation coefficient between the peak Ck and QRS score is 0.48(p<0.05). 5) In the inferior wall infarction, the average QRS score is a 4.5 and the correlation coefficient between the leak CK and QRS score is 0.79(p<0.05).

Although some employees working for Seoul Metropolitan Subway Cooperation are working at the noisy workplaces, they has been excluded from Special Periodic Health Examination Program. And some workers complained of hearing loss or tinnitus. So, this study was carried out to investigate the prevalence rate of Noise Induced Hearing Loss of employees(10,792) working for Seoul Metropolitan Subway Cooperation. The number of subjects were total 10,792 with 10,355 men and 437 women. A questionnaire survey, otological examination, Rinne test, pure tone audiometric tests were performed and through the first and second screening audiometric examination, 605 workers were selected after excluding employees with past otologic problems, recent exposure to high level noise, and under medications. and the results were as follow; 1. Among 10,792 workers, 4 workers(0.037%) diagnosed as NIHL and 601 workers(5.56%) as early NIHL. As workers grew older, the prevalence rate of NIHL and early NIHL became more rising. 2. The prevalence rate of NIHL and early NIHL was different between work site. After age adjustment, The prevalence rate of NIHL and early NIHL was 23.74% in Train repairmen{80dB(A)}, 3.1% in Station staffs{below 70dB(A)}, 2.53% in Train crew{below 70dB(A)}, 2.1% in Office workers. 3. The perception rate of necessities of ear plug in NIHL and early NIHL was below 55% and wearing rate of ear plug in NIHL and early NIHL was 1.1% In conclusion, some employees who was under working environment in Seoul Metropolitan Subway Cooperation should be monitored to prevent hearing impairment and would be needed health education.

We report a case of neurilemmoma of deep peroneal nerve sensory branch that triggered sensory change with compression test on lower extremity. After resection of tumor, there are evoked thermal changes on pre- and post-operative infrared (IR) thermographic images. A 52-year-old female presented with low back pain, sciatica, and sensory change on the dorsal side of the right foot and big toe that has lasted for 9 months. She also presented with right tibial mass sized 1.2 cm by 1.4 cm. Ultrasonographic imaging revealed a peripheral nerve sheath tumor arising from the peroneal nerve. IR thermographic image showed hyperthermia when the neurilemoma induced sensory change with compression test on the fibular area, dorsum of foot, and big toe. After surgery, the symptoms and thermographic changes were relieved and disappeared. The clinical, surgical, radiographic, and thermographic perspectives regarding this case are discussed.

Measurements of mitral flow velocity by pulsed Doppler echocardiography are very useful in evaluating left ventricular diastolic filling properties. In hypertensive patients, abnormalities of diastolic function may precede systolic abnormalities and may serve as a more sensitive marker of end organ damage. We estimated left ventricular nass by 2-D echo short axis area-length method and compared with peak mitral flow velocity in early diastole(PFVE)and during atrial systolic(PFVA). There was a significant increase of LV mass and LV mass indices in the hypertensive patients and PFVE/PFVA ratio was decreased in them. Aithough there was no relationship between blood pressure and PFVE/PFVA ratio, a significant relationship was demonstrated between LV mass index and PFVE/PFVA ratio in the hypertensive patients.

BACKGROUND: The purpose of this study was to evaluate the postoperative magnetic resonance imaging (MRI) results of minimal-tying (one medial-row tie among 4 medial-row sutures) on the medial-row in double-row suture-bridge configuration (2x2 anchor with 4x4 suture stands). METHODS: From 2011 March to 2012 July, 79 patients underwent arthroscopic rotator cuff repair using 2x2 anchor double-row configuration. The mean age was 61.3 years (range, 31-81 years). Two double-loaded suture anchors were used for medial-row. Four medialrow stitches were made with only one medial-row knot-tying (the most anterior suture). Lateral-row was secured using the conventional suture-bridge anchor technique; all 4 strands were used for each anchor. Repair integrity was evaluated with MRI at mean 6.2 months postoperatively. Retear and the pattern of retear, change of fatty infiltration, and muscle atrophy of supraspinatus were evaluated using pre- and postoperative MRI. RESULTS: Repaired tendon integrity was 38 for type I, 30 for type II, 6 for type III, 4 for type IV, and 1 for type V, according to Sugaya classification. Considering type IV/V as retear, the rate was 6.3% (5 out of 79 patients). Medial cuff failure was observed in 4 patients. Fatty atrophy of supraspinatus was significantly improved postoperatively according to Goutallier grading (p=0.01). The level of muscle atrophy of supraspinatus was not changed significantly after surgery. CONCLUSIONS: Minimal tying technique with suture configuration of four-by-four strand double-row suture-bridge yielded a lower retear rate (6.3%) in medium to large rotator cuff tears.

OBJECTIVE: Keyhole craniotomy is a modification of pterional craniotomy that allows for use of a minimally invasive approach toward cerebral aneurysms. Currently, mini-pterional (MPKC) and supraorbital keyhole craniotomies (SOKC) are commonly used. In this study, we measured and compared the geometric configurations of surgical exposure provided by MPKC and SOKC. METHODS: Nine patients underwent MPKC and four underwent SOKC. Their postoperative contrast-enhanced brain computed tomographic scans were evaluated. The transverse and longitudinal diameters and areas of exposure were measured. The locations of the anterior communicating artery, bifurcation of the middle cerebral artery (MCAB), and the internal carotid artery (ICA) terminal were identified, and the working angles and depths for these targets were measured. RESULTS: No significant differences in the transverse diameters of exposure were observed between MPKC and SOKC. However, the longitudinal diameters and the areas were significantly larger, by 1.5 times in MPKC. MPKC provided larger operable working angles for the targets. The angles by MPKC, particularly for the MCAB, reached up to 1.9-fold of those by SOKC. Greater working depths were required in order to reach the targets by SOKC, and the differences were the greatest in the MCAB by 1.6-fold. CONCLUSION: MPKC provides larger exposure than SOKC with a similar length of skin incision. MPKC allows for use of a direct transsylvian approach, and exposes the target in a wide working angle within a short distance. Despite some limitations in exposure, SOKC is suitable for a direct subfrontal approach, and provides a more anteromedial and basal view. MCAB and posteriorly directing ICA terminal aneurysms can be good candidates for MPKC.

OBJECTIVE: Acute subdural hematoma (ASDH) with good initial Glasgow Coma Scale (GCS) score 13-15 is generally regarded as a mild head injury. However, the risk increases when significant amount of hematoma with midline shift exists. This study is to evaluate the clinical outcomes of patients with good neurological scores in spite of significant amounts of ASDH, and to compare the outcomes according to the treatment modalities. METHODS: Sixty patients with initial GCS score 13-15 in spite of significant amounts of ASDH and midline shifts were enrolled. They were divided into groups according to age, sex, side of location, initial GCS score, midline shift, and hematoma thickness. According to the therapeutic modalities, early craniotomy and initially conserved groups were identified, and initially conserved group was further classified into persistently conserved and delayed operation groups. The outcomes were measured by Glasgow Outcome Scale. RESULTS: Initial GCS score was a significant factor that influenced the final outcome (p=0.001). The outcomes were good in both early craniotomy and initially conserved groups without significant differences (p=0.268). Fifteen of initially conserved 49 patients underwent delayed operations from neurological deteriorations, but the outcomes were good without significant differences from persistently conserved group (p=0.481). CONCLUSION: Initial GCS score is an important factor that influences the clinical outcome. These patients can be conserved under close observations without early preventive craniotomies if no deteriorations are seen in the acute stage. Only those with delayed deteriorations may require simple operations such as burr hole trephinations which still guarantee good outcomes.
