Erdheim-Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis with multi-organ involvement. Bones, cardiovascular system, central nervous system, kidney, skin and many different organs can be involved but laryngeal involvement has not been reported in literatures. The diagnosis of ECD was based on clinical manifestations and immunohistochemical findings including CD68(+), CD1a(-) and S100(-). Currently, Interferon-a is the most extensively studied agent in the treatment of ECD and serves as the 1st line of treatment. Surgical resection of involved lesions can be tried but it leads to temporary improvement. A 60-year-old man visited with respiratory symptoms because of ECD with laryngeal involvement. We resected the obstructive lesion to relieve the symptoms. Tissue biopsy gave a diagnosis of ECD. As it is rare to encounter ECD involving the larynx, we report this case with a review of literatures.

Effect of acetylcholine(ACh) and McN-A-343 on porcine coronary artery and rabbit thoracic aorta were investigated in isolated preparations with or without intact endothelium. In the porcine coronary artery, ACh produced concentration dependent contraction which was greater in rings without the endothelium than in intact endothelial rings, but McN-A-343 did not alter the basel tension in both tissues. ACh relaxed contraction induced by 5-hydroxytryptamine(5-HT) in only intact endothelial rings, while NcN-A-343 inhibited the 5-HT induced tension in both preparations dose dependently. Carbachol elicited a prominent contraction in both tissues. The carbacol-induced tension was markedly inhibited by McN-A-343 in either rings with or without endothelium, while ACh contracted further the tension. ACh and McN-A-343 did not after the KCi induced tension, but clearly potentiated the contraction induced by Bay K 8644 in intact endothelial rings. In rabbit thoracic aorta, ACh elicited contraction in a concentration-dependent fashion which was potentiated by removal of endothelium, but McN-A-343 did not affect the basal tension of both rings. ACh inhibited the 5-HT-induced contraction in only intact endothelial ring, but McN-A-343 did not change the contraction of both rings. Conclusively, ACh produces endothelium-dependent relaxation in both arteries, while McN-A-343 elevated endothelium-independent inhibition to 5-HT or carbachol-induced tension.

The gastrointestinal polyp is a premalignant lesion in varying degree. According to the size, the pathology and the location of polyps, it should be removed. Polyps in the gastrointestinal tract can be removed by surgical excision, electrosurgery, cryotherapy, regional radiotherapy and laser therapy with some limitations. Considerable advance in therapeutic endoscopy as well as in diagnostic endoscopy along with newly developed instruments has now made it possible to excise gastrointestinal polyps by means of high frequency generator. We have underwent endoscopic polypectomy, strip biopsy and "O" ring ligation on gastric polyps in 112 patients who visited in this hospital from July l988 to January 1994, and the clinical characteristics including histopathology has been evaluated. Removed polyps were variable in size from less than 0.5 cm up to 4cm. Finally, we concluded that endoscopic polypectomy is a safe and relativly simple procedure and postpolypectomy complication can be considerably reduced by conservative antiulcer therapy.

Inducible nitric oxide synthase (iNOS) expression of several organs on the lipopolysaccharides (LPS)-injected rats and on excisional wound was observed by immunohistochemical methods to investigate iNOS-positive cells during inflammation. iNOS expression was induced in response to LPS in the brain and these reactions were observed in the choroidal epithelium, ependymal cells and a few of nerve cells and fiber. A more intensive reaction of nerve cell and fiber was mainly observed in the corpus callosum and hypothalamus. Induction of iNOS of the lung was observed in alveolar macrophage, smooth muscle, pneumocytes and inflammatory cells infilterated in the alveolar septum. iNOS expression of the liver was detected in Kupffer cells, hepatocytes, bile duct and inflammatory cells of spotty necrosis. The cardiac muscle and endothelial cell of the heart showed positive iNOS expression. In the excisional wound, inflammatory cells including macrophages, neutrophil and fibrobast showed iNOS expression and mainly detected necrobiotic layer. Collectively, iNOS expression was induced in the several cell types during inflammatory process. So for better understanding the function of iNOS, more research should be done in relation to each cell type of organ.

PURPOSE: The purpose of this study was to present methods and results for the modified Phemister operation, with a suture anchor added for augmentation of the conoid ligament in cases of acute dislocation of the acromioclavicular joint. MATERIALS AND METHODS: We evaluated 14 cases of acute dislocation of the acromioclavicular joint. This included 11 cases of Rockwood type 3, and 3 cases of type 5. The mean age of patients was 45.2 years. We operated on them using an anchor for augmentation of the conoid ligament in the modified Phemister operation. The average follow-up period was 14 months and post-operative clinical analysis was conducted using the Weitzman classification, VAS Score, Constant Score and KSS Score. RESULTS: According to Weitzman scores, 13 cases were evaluated as excellent, and one case was good. They had mean joint ranges of forward elevation of 170.7degrees, lateral elevation of 166.4, external rotation of 68.2, and internal rotation to the level of T7. The mean VAS Score was 1.9, mean Constant Score 90.8, and the mean KSS Score 91. Radiologic analysis indicated that all cases had a good result. CONCLUSION: The modified Phemister operation with a suture anchor added for augmentation of the conoid ligament is very effective clinically in acute dislocations of the acromioclavicular joint.

BACKGROUND: We purposed to systemically review studies investigating the prophylactic effect of both pharmacological and non-pharmacological modalities against rocuronium induced withdrawal movement (RIWM) in the Korean population. METHODS: Literature search was performed using MEDLINE, EMBASE, CENTRAL, Koreamed, KMBASE, KISS and RISS up to March 2014. Randomized controlled trials (RCTs) comparing pharmacological and non-pharmacological interventions with placebo aimed for the Korean population were included. Outcome measures were the incidence and severity of RIWM. We conducted subgroup analyses according to each intervention method. RESULTS: Data were analyzed from 41 RCTs totaling 4,742 subjects. The overall incidence of RIWM was about 80% (range 56-100%). Incidence and severity of RIWM were significantly reduced with lidocaine (risk ratio [RR] 0.60, 95% CI 0.49-0.74; standardized mean difference [SMD] -0.74, 95% CI -1.05 to -0.44), opioids (RR 0.28, 95% CI 0.18-0.44; SMD -1.71, 95% CI -2.09 to -1.34) and hypnotics (RR 0.36, 95% CI 0.25-0.52; SMD -2.20, 95% CI -2.62 to -1.79). Regardless of tourniquet use, lidocaine showed a prophylactic effect against incidence and severity of RIWM: tourniquet (RR 0.36, 95% CI 0.21-0.62; SMD -1.51, 95% CI -2.15 to -0.86); non-tourniquet (RR 0.58, 95% CI 0.47-0.71; SMD -0.74, 95% CI -1.05 to -0.44). Dilution and slow injection of rocuronium decreased incidence and severity of RIWM: dilution (RR 0.47, 95% CI 0.39-0.56; SMD -1.64, 95% CI -2.47 to -0.81); slow injection (RR 0.34, 95% CI 0.17-0.70; SMD -2.13, 95% CI -2.74 to -1.51). CONCLUSIONS: The greater part of pharmacological and non-pharmacological interventions showed prophylactic effect against the incidence and severity of RIWM in the Korean population.

PURPOSE: We assessed the clinical results after the operative treatment of type 2 SLAP lesion with stiffness. MATERIALS AND METHODS: 13 patients who had SLAP lesion with stiffness were treated with arthroscopic capsular release, SLAP repair and treatment of the associated lesion. The average follow-up period was above 12 months. RESULTS: The postoperative mean VAS was scored 1.5 and the postoperative ROWE score was 92.3, which showed a significant improvement after the operation (P<0.001). The mean range of motion was a significantly improved after the operation (P<0.001). The ROWE score was excellent for all the cases. CONCLUSION: Arthroscopic capsular release and SLAP repair and treatment of the associated lesion in patients with type 2 SLAP lesion with stiffness are effective treatments for the increasing the range of motion and decreasing the pain.
