Takayasu's arteritis is an arteritis of undetermined etiology, which affects the aorta, the proximal portions of its major branches, and the pulmonary arteries, and causes coarctation, occlusion, or aneurysmal dilatation of the affected vessels. Authors has reported 9 cases in 1973, and another 24 cases in 1977. Thereafter, during next 4 years, authors experienced another 42 cases and obtained some additional results. The results are as follows: 1. Among 75 cases, 10 are male and 65 female patients with sex ratio of 1:6.5, and about 2/3 of total patients are under 30 years of age. 2. Headache, dizziness, absent or weak radial pulse and hypertension are the most common symptoms and signs. 3. Conventional chest roentgenography may be helpful but not specific in diagnosis of Takayasu's arteritis. 4. The aortographic findings are characteristic and pathognomonic in diagnosis of Takayasu's arteritis. In our series, the most common findings are stenosis or occlusion of subclavian artery, diffuse narrowing and aneurysmal dilatation of abdominal aorta and its branches, narrowing with irregular contour of descending thoracic aorta, and renal artery involvement. 5. Involvement of the aorta was classified as extensive type in 38 cases, descending thoracic and abdominal type in 22 cases and arch type in 15 cases. 6. As total aortography in cluding abdominal aorta uncovers evidence of unsuspected involvement of aorta and its branches, it is of paramount importance in the diagnosis of Takayasu's arteritis.

Percutaneous transhepatic biliary drainage was successfully made 20 times on 17 patients of obstructivejaundice for recent 1 year since June 1981 at department of radiology in Seoul National University Hospital. Thecauses of obstructive jaundice was CBD Ca in 13 cases, metastasis in 2 cases, pancreatic cancer in 1 case and CBDstone in 1 case. Percutaneous transhepatic biliary drainage is a relatively easy, safe and effective method whichcan be done after PTC by radiologist. It is expected that percutaneous transhepatic biliary drainage should bedone as an essential procedure for transient or permanent palliation of obstructive jaundice.

BACKGROUND: Many physicians hesitate to discuss do-not-resuscitate (DNR) orders with patients or family members in critical situations. In the intensive care unit (ICU), delayed DNR decisions could cause unintentional cardiopulmonary resuscitation, patient distress, and substantial cost. We investigated whether the timing of DNR designation affects patient outcome in the medical ICU. METHODS: We enrolled retrospective patients with written DNR orders in a medical ICU (13 bed) from June 1, 2014 to May 31, 2015. The patients were divided into two groups: early DNR patients for whom DNR orders were implemented within 48 h of ICU admission, and late DNR patients for whom DNR orders were implemented more than 48 h after ICU admission. RESULTS: Herein, 354 patients were admitted to the medical ICU and among them, 80 (22.6%) patients had requested DNR orders. Of these patients, 37 (46.3%) had designated DNR orders within 48 hours of ICU admission and 43 (53.7%) patients had designated DNR orders more than 48 hours after ICU admission. Compared with early DNR patients, late DNR patients tended to withhold or withdraw life-sustaining management (18.9% vs. 37.2%, p = 0.072). DNR consent forms were signed by family members instead of the patients. Septic shock was the most common cause of medical ICU admission in both the early and late DNR patients (54.1% vs. 37.2%, p = 0.131). There was no difference in in-hospital mortality (83.8% vs. 81.4%, p = 0.779). Late DNR patients had longer ICU stays than early DNR patients (7.4 ± 8.1 vs. 19.7 ± 19.2, p < 0.001). CONCLUSIONS: Clinical outcomes are not influenced by the time of DNR designation in the medical ICU. The late DNR group is associated with a longer length of ICU stay and a tendency of withholding or withdrawing life-sustaining treatment. However, further studies are needed to clarify the guideline for end-of-life care in critically ill patients.

PURPOSE: This study was conducted to assess reported industrial accidents and non-reported industrial accidents that took place in 63 small and medium sized manufacturing industries located in Daegu and Gyeongsangbuk-do in the year of 2009. METHODS: During the period from January to December 2009, the number of industrial accidents that happened each month was examined according to the characteristics of industry, industrial accidents, workers with industrial accidents, treatment, as well as causes and treatment of the non-reported. RESULTS: The total incidence rate of industrial accidents was 3.48%, of which only 0.31% reported. The incidence rate in packing and distribution among manufacturing workplace, and in the industry with 50~99 employees, was higher than the other groups. Of the non-reported, over 80% in required under 10 days of medical treatment, and 56% in required cost of less than 100,000 won. Kappa values were 0.771 concurrence in opinions for causes of non-reported, and 0.571 concurrence in opinions for management termination of non-reported between the employees and employer. CONCLUSION: It is suggested that more supportive policy and precise, nationwide survey on the actual state of industrial accidents, including non-reported cases, be implemented to efficiently manage industrial accidents.

A major problem in the repair of the torn Achilles tendon has been providing the restoration of the anatomic continuity such that virtually normal plantar flexion power and ankle mobility result. Continuity should be restored without subsequent pain, disconfiguration, occupational limitations. If possible, postoperative complications, or tendon-rerupture should be avoided. Surgeons have long advocated the use of strips of facia and other tissues, including the plantaris tendon, to reinforce the repair of the torn Achilles tendon, The repair effected by these methods not infrequently is bulky and not too secure. Non-absorbable suture materials utilizing in the end to end anastomosis of the torn Achilles tendon cause sinus formation and discharge of suture materials. A secure method of repair for the tom Achilles tendon, which decreases sinus formation and is not bulky, should be required. The plantaris tendon, which has been used as a reinforcing material, can be utilized in the end-to-end anastomosis of the torn Achilles tendon by detaching from the muculotendinous junction. The 11 patients with the torn Achilles tendon were treated by end-to-end anastomosis using the plantaris tendon as suture material. The postoperative results were staisfactory without significant functional deficit and complication.

Power lawn mower is a useful equipment for landscape, but it can introduce a new eye trauma. These ocular injuries are recently increasing in Korea. To inform the possibility of visual loss, we reviewed medical records of 11 patients with intraocular foreign bodies by power lawn mowers. All of patients were men and lawn mower operators themselves. Nature of foreign bodies was metallic in 10 eyes(91%), Inlet was through the cornea in 10 eyes(91%), and intraocular location was at the vireo retina in 8 eyes(73%). At final follow-up, best corrected visual acuities were worse than counting fingers in 4 eyes(36%). Safety cover or halmet is needed for prevention of eye trauma caused by power lawn mower, however, more important, operators themselves should follow the ordinary safety rules.

Hypertensive encephalopathy is an acute clinical syndrome that shows central nerve dysfunction with sudden and marked elevation in blood pressure. But its pathophysiologic mechanisms, clinical courses and prognosis are still not clear. In order to study clinical manifestations and response to treatment in patients with hypertensive encephalopathy, we reviewed 45 patients with hypertensive encephalopathy who were admitted in Dept. of Internal Medicine, National Medical Center, from January 1975 to December 1984. The following results were obtained: 1) The ratio of male to female was 1.1:1. The peak age of incidence was in the 6th and 7th decade with mean age of 57.5 years. 2) Among 45 patients, only 29 had known history of hypertension and the average duration of hypertension was 8.1+/-3.6 years. 3) The most common sympotm was severe headache (68.9%). And altered consciousness, nausea and/or vomiting, focal neurologic signs and visual disturbance were also common symptoms in decreasing order of frequency. 4) Funduscopic examination showed hypertensive retinopathy in 20 of 24 (91.7%) patients and lumbar puncture revealed increased CSF pressure in 12 of 20 (60%) patients. 5) In most patients, the mean interval to symptomatic improvement was 2.1 days after administration of anti hypertensive agents, but in 6 patients with initial mean arterial blood pressure above 170mmHg, 4 patients showed delayed response and 2 patients were expired.

The efficacy of endovascular treatment (EVT) in patients with posterior circulation stroke has not been proven. Two recent randomized controlled trials failed to show improved functional outcomes after EVT for posterior circulation stroke (PC-EVT). However, promising results for two additional randomized controlled trials have also been presented at a recent conference. Studies have shown that patients undergoing PC-EVT had a higher rate of futile recanalization than those undergoing EVT for anterior circulation stroke. These findings call for further identification of prognostic factors beyond recanalization. The significance of baseline clinical severity, infarct volume, collaterals, time metrics, core-penumbra mismatch, and methods to accurately measure these parameters are discussed. Furthermore, their interplay on EVT outcomes and the potential to individualize patient selection for PC-EVT are reviewed. We also discuss technical considerations for improving the treatment efficacy of PC-EVT.
