1.Isokinetic Muscle Strength and Muscle Endurance by the Types and Size of Rotator Cuff Tear in Men.
Clinics in Shoulder and Elbow 2014;17(4):166-174
BACKGROUND: Our study was to determine the effect on shoulder isokinetic muscle strength and muscle endurance in isolated full-thickness supraspinatus tendon tear and combined other rotator cuff tear. METHODS: Total of 81 male patients (mean age 57.8 +/- 7.4 years) who were diagnosed as a full-thickness supraspinatus tendon tear were included. They were classified into isolated or combined tear. The isokinetic muscle strength and muscle endurance were measured using the Biodex multi-joint system PRO(R) (Biodex Medical Systems, Shirley, NY, USA) in following movements: shoulder abduction, adduction, flexion, extension, external rotation, and internal rotation. Then, the difference in muscle function according to the type of tears were assessed. Fifty-seven patients had isolated supraspinatus tendon (mean age 56.9 +/- 7.3 years). They were classified into either anteroposterior tear or modified mediolateral tear. The size were measured using T2-weighted magnetic resonance imaging scans in sagittal plane. RESULTS: Between subjects categorized into the type of tear, we found significant inter-categorical differences in isokinetic muscle strength during abduction, adduction, flexion, extension, and internal rotation, and in muscle endurance during flexion, extension, and internal rotation. Anteroposterior diameter tear, we did not show significant differences in either isokinetic muscle strength or muscle endurance during any movements. However, with modified mediolateral diameter, we found significant differences with isokinetic muscle strength during adduction, and in muscle endurance the external rotation and internal rotation. CONCLUSIONS: We found that a supraspinatus tendon tear associated with more numbers of rotator cuff tears has lower isokinetic muscle strength and muscle endurance than a tear found alone.

2.Therapeutic Hypothermia in Traumatic Brain injury; Review of History, Pathophysiology and Current Studies.
Korean Journal of Critical Care Medicine 2015;30(3):143-150
The fact that therapeutic hypothermia (TH) has lowered intracranial pressure and protected brain in severe traumatic brain injury (TBI) is well known throughout past sources and experimental data. In this paper, the result of TH in TBI needs to be confirmed. The result of North American Brain Injury Study; Hypothermia (NAVIS-H) 1 and 2, Eurotherm3235, Japan trauma society study was reviewed throughout randomized controlled study which performed recently. The prognosis was not confirmed throughout TH in NAVIS-H1; however, there was statistical significance among the group of 45 years or less and below 35 degree in celcius which checked when he or she visited initially. Hence, NAVIS-H2 study was preceded. In patient who had surgically removed hematoma, the effects of TH were proved compared to diffuse brain damage in NAVIS-H2 study. This was found in the result of Japan neurotrauma data bank. Eurotherm study has been doing, which leads to collect many data later on. The TBI of TH makes them better prognosis in patients who had surgically removed hematoma and lowered initial body temperature. Later on, it is considered further study is necessary.

The epidural injection of corticosteroid reduces the inflammatory process of the neural structure and its neighbor structures. Morphine, also injected epidurally, has been reported to alleviate severe pain with the short-acting property. In attempt to prolong the effectiveness of pain relief, we have studied the effect of the epidural injection of the morphine and steroid frorg May 1987 to Oct. 1987, and compared with the effect of the epidural injection of the steroid and local anesthetics from Jan. 1986 to Oct. 1987. In this study, we obtained following results; 1. The major causative diseases were herniated necleus pulposus in 34 cases(48.5%), spinal stenosis in 16 cases(22.9%) and spondylolisthesis in 9 cases(12.9%). 2. In morphine-injected group, 100% of acute group and 92.3% of chronic group was improved. In non-morphine injected group, there was no significant difference between the acute and chroinc groups. 3. The effect of epidural morphine and steroid was as follows; Complete relief 14 cases (63.6%), marked improvement 5 cases(22.7%), moderate improvement 2 cases(9.2%) and no relief 1 case(4.6%). The overall improvement was resulted in 21 cases(95.4%). 4. The effect of epidural steroid and local anesthetics was as follows; Complete relief 10 cases(20.8%), marked improvement 14 cases(29.2%), moderate improvement 12 cases(25%~ and no relief 12 cases(25%). The overall improvement was resulted in 36 cases(75%). 5. The average duration of pain relief was 2.5 months in morphine injected group and 1.3 months in non-morphine injected group. 6. The side effects associated with opiate, such as generalized pruritus, nausea, vomiting and urinary retention were reported in 16 cases(72.7%), but responded readily to Naloxone injection and subsided within 24 hours. It is considered that epidural injection of morphine and steroid prolong the effect and duration of pain relief for low back pain and sciatica when compared with the epidural injection of steroid and local anesthetics.

STUDY DESIGNS: A retrospective study. OBJECTIVES: To analyze the clinical and radiological outcomes of spontaneous reduction via minimally invasive transforaminal lumbar interbody fusion (Mini-TLIF) as the treatment for low-grade symptomatic spondylolisthesis. SUMMARY OF LITERATURE REVIEW: Although minimally invasive transforaminal lumbar interbody fusion is technically demanding, this procedure is an effective method for spontaneous reduction of low grade spondylolisthesis. MATERIALS AND METHODS: We analyzed consecutive series of 41 patients with low grade spondylolisthesis who underwent minimally invasive transforaminal lumbar interbody fusion, between April 2008 and July 2009. The minimum follow-up period was 2 years. Clinical evaluation was performed by an analysis of Visual Analogue Scale and Oswestry Disability Index. For the radiological evaluation, disc space height, slip percentage, and slip angle were analyzed. At the final follow-up, the fusion rate was analyzed according to the Bridwell's anterior fusion grade. RESULTS: For the evaluation of clinical outcomes, the Visual Analogue Scale for back pain decreased from 6.8+/-1.2 to 2.0+/-1.1, and that for radiating pain decreased from 7.9+/-1.3 to 1.7+/-1.1. Oswetry Disability Index decreased from 38.5+/-8.4 to 13.4+/-6.1. For the radiological evaluation, disc space height increased from 8.4+/-2.14mm to 11.8+/-1.54mm(P<0.05), slip percentage was reduced from 18.4+/-5.1% to 13.3+/-3.1%(P<0.05) and slip angle decreased from 10.6+/-4.5degrees to 6.2+/-3.4degrees (P<0.05). At the final follow-up, radiological union was obtained in 38 cases (92.7%). CONCLUSIONS: We conclude that minimally invasive transforaminal lumbar interbody fusion appears to be an effective method for spontaneous reduction of low grade spondylolisthesis if the surgeon becomes familiar with this method.

A total 73 cases of primary malignant bone tumors was reviewed and analysed clinically at the department of orthopaedic surgery, Kosin medicsl center, Pusan, Kores for 11 years from January, 1975 to December, 1985. The results were obtained as follows ; l. In the 73 cases of primsry malignant bone tumors, osteogenic sarcoma was the most common primary malignant bone tumor (57%) and followed by chondrossrcoma (10%), multiple myeloma (8%). 2. Average survival times according to each primary malignant bone tumors was more than 3 years in chondrosarcoma, reticulum cell sarcoma, and synovial sarcoma, 28 months in osteogenic sarcoma, and 7 months in Ewings sarcoma. Ewings sarcoma had the worse prognosis and the slowly progressing tumors-chondrosarcoma, reticulum cell sarcoma and synovial sarcoma are needed long term follow up. 3. In osteogenic sarcoma, the prognosis was better when developed in their 3rd decsde than when developed in their 2nd decade. 4. There is a slight difference in average survival time on the location of the site, for example when tumor is located in the distal femur, the prognosis was worst. 5. There is no difference in the prognosis. The mode of treatment did not effect to their prognosis. 6. It was clear that the tumors which had not been responded to chemotherapy or radiation therapy had poorer prognosis. Chondrosarcoma, fibrosarcoma and synovisl sarcoma were considered as slowly progressed tumors, and so it may be benefit to the patients that chemotherapy and/or radiotherapy were prescribed.

Chordoma is relatively rare and slowly growing tumor arising from notochordal remnant. The tumor is locally infiltrative rather than metastatic. Distant metastasis occured in 5% of Gentil & Coley's cases and 43% of Higinbotham et als cases. Usual sites of metastasis sites were lung, liver adrenal gland and lymph nodes. In 1922, Stewart reported first case of extrapulmonary metastatic chordoma in muscle & subcutaneous layer, which was extremely rare. We have experienced a case of wide spread multiple metastasis to muscle & subcutaneous tissue from primary sacrococcygeal chordoma. The case was 26 years old man, who have had multiple metastatic lesions in trunk, upper & lower extremities. They located in muscle and subcutaneous fat layer. In some lesions neurovascular structure was involved. We have treated the metastatic lesions by complete surgical excision, and they were confirmed as soft tissue chordoma by histologic examination.
