BACKGROUND: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. METHODS: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%–75%, Group C: 25%–50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. RESULTS: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). CONCLUSIONS: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

BACKGROUND: This study investigated the efficacy and safety of combined subacromial and intravenous patient-controlled analgesia for control of postoperative pain after arthroscopic rotator cuff repair. METHODS: Between May 2012 and August 2014, 60 patients who underwent arthroscopic rotator cuff repair with acromioplasty and received patient-controlled analgesia were studied prospectively. Cases were divided into 2 groups: combined subacromial and intravenous infusion group (group A, 30 cases) and solitary intravenous infusion group (group B, 30 cases). The visual analogue scale was used to record the patient's level of pain every 12 hours during postoperative 72 hours and the following 48 hours after the suspension of patient-controlled analgesia. RESULTS: The mean preoperative visual analogue scale score was 7.8 in group A and 7.6 in group B, and the immediate postoperative visual analogue scale score was 7.9 and 8.1 for each group. At postoperative time (From 12 hours to 72 hours after operation), the scores of combined subacromial and intravenous infusion were significantly lower than those of solitary intravenous infusion. Significant difference in the frequency of supplemental analgesic injections was observed between group A and group B (p=0.008). However, no significant difference in complication rate was observed between the two groups (p=0.562). CONCLUSIONS: Combined subacromial and intravenous patient-controlled analgesia after arthroscopic rotator cuff repair is more effective than solitary intravenous infusion without significantly increasing complications. Therefore, combined subacromial and intravenous patient-controlled analgesia could be a effective pain control method.

Basaloid follicular hamartoma(BFH) is a rare, benign adnexal tumor with a wide clinical appearance spectrum. A characteristic finding is multifocal islands in the papillary dermis and branching cords of basaloid epithelial cells in continuity at various sites with the basal layer of the epidermis and the hair follicles. We present a case of basaloid follicular hamartoma combined with basal cell epithelioma that developed on the tip of the nose in a 75-year-old man. To our knowledge, this is the first case report of basaloid follicular hamartoma combined with basal cell epithelioma in the Korean literature.

Herpes zoster oticus (Ramsay Hunt syndrome) is characterized by facial nerve paralysis associated with vesticular eruptions and cochleovestibular symptoms. Many evidences have supported that it is caused by the reactivation of latent varicella-zoster virus in the geniculate ganglion. Recently we experienced a case 49-year-old man presented severe vertigo and a vesicular eruptions of auricle and external ear canal. It is an unusual variant of herpes zoster oticus that involves only vestibular nerve without facial nerve palsy and hearing loss. We believe this case results from reactivation of latent varicella zoster virus in the vestibular ganglion and report with a review of literatures.

In recent trends of popularized sports and increased industrial hazards, we need the therapeutic modality in clinical setting, as a training and testing device for sports practicians, and as a method for scientific examination of post-operative status of muscles and joint function for orthopedist. Isokinetic exercise with Cybex II overcomes many biomechanical factors and can be used for fatigued patients by control of resistance. We examined internal rotator and external rotator muscle force of the shoulder joint, in order to acquire the isokinetic normative data of the shoulder for clinical use. The result were as follows 1. Strength and Power decreased as ages getting old, and there was significantdiminishbetween5th decade and 6th decade. 2. Power endurance did not decrease significantly as ages getting old. 3. The mean values of strength and power in internal rotator were higher than external rotator.

BACKGROUND: Onlay vein patch coronary angioplasty has been known to be an option for coronary artery stenosis in the selective iesions MATERIAL AND METHOD: During the period between July 1997 and August 1999, coronary angioplasty using autologous saphenous vein was done on 16 sites in 14 cases for the stenotic lesion at the bifurcation area and significantly stenosis distal to anastomosis. RESULT: Early patency of the angioplasty site was 85.7% at postoperative day 7. There was no statistically difference in graft patency, operative parameters, and complications compared to conventional anatomosis(p>0.05). CONCLUSIONS: Despite the small number of cases, the patency rate of the coronary patch angioplasty was comparable to the conventional CABG. Coronary artery only patch angioplasty could be performed in highly selected coronary arteries.

BACKGROUND: Early patency of the coronary artery bypass grafting is determined mainly by surgical technique and status of coronary artery. We analyzed the early result, focusing on the relationship between postoperative angiographic findings and the patency rate. MATERIAL AND METHOD: During the period of July 1997- August 1999, 86 cases of CABG were performed and the postoperative coronary artery angiography was done in 76 cases on postoperative day 7 to assess the graft patency. RESULT: Overall graft patency was 90.2% on the angiographic finding. Factors influencing the early graft occlusion were the surgeon's experience, small coronary artery size less than 1.5mm in diameter, coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site(p<0.001). Operative mortailty was 2.3%. Early recurrence of the symptom was 19.8% during the follow up period. CONCLUSIONS: We examined the postoperative coronary angiography and found that the surgeon's experience, small coronary artery size less than 1.5mm in diameter, bypass surgery on the coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site were the factors for the graft occlusion.

Background:
As the population of patients with end-stage renal disease has grown older, the proportion of patients with poorly preserved vasculature has concomitantly increased. Thus, arteriovenous grafts (AVG) have been used more frequently to access blood vessels for hemodialysis. Despite this increasing demand, studies of AVG are limited. In this study, we examined the surgical outcomes of upper-limb AVG creation.
Methods:
Among the arteriovenous fistula formation procedures performed between January 2014 and March 2019 at Dankook University Hospital, 42 cases involved AVG creation. We compared patients in whom the axillary vein was used (group A; brachioaxillary AVG [B-Ax AVG]; n=20) with those in whom upper limb veins were used (group B; brachiobasilic AVG or brachioantecubital AVG; n=22).
Results:
The 1-year primary patency rate was higher in group A than in group B (57.9% vs. 41.7%; p=0.262). The incidence of postoperative complications was not significantly different between groups.
Conclusion
AVG using the axillary vein showed no major differences in safety or functionality compared to AVG using other veins. Therefore, accounting for age, underlying disease, and expected patient lifespan, B-Ax AVG can be considered an acceptable surgical method.

BACKGROUND: To analyze the morphologic characteristics of low density lymph node in etiologic differentiation of lymphadenopathy, emphasizing the different features between tuberculosis and lung cancer, on contrast enhanced CT scan,. METHOD: A total of 64 patients who showed low density lymph nodes on chest CT scan were analyzed. Primary causes were tuberculosis (n=28), lung cancer (n=27), malignant lymphoma (n=5) and metastasis from extrathoracic malignancies (n = 4). CT scan was performed with 10mm slice thickness and 7 characteristic features were evaluated: location,size, presence or absence of the nonnecrotic lymph node, calcification, perinodal fat obliteration, thickness and evenness of the enhancing rim. RESULTS: In patients with tuberculous lymphadenopathy, lymph nodes with uneven (68.0%) and thick (62.1%) enhancing rim were more common than lung cancer (p<0.05). Low density lymph nodes with less than 1cm in size were found only in tuberculous lymphadenopathy(n=10). In 48.2% of patients with lung cancer, more than 1 nonnecrotic enlarged lymph node were coexisted, whereas 21.4% in patients with tuberculous lymphadenopathy(p=0.06). However, the size, location and calcification were not statistically significant between tuberculous lymphadenopathy and lung cancer. CONCLUSION: Tuberculous lymphadenopathy is strongly suggested when enhancing rim of enlarged lymph nodes is uneven and thick, when the coexisting nonnecrotic lymph nodes are few in number and when central low density is encountered in normal sized lymph nodes.
