Osteochondromadevelop most commonly at distal femur, proximal humerus and proximal tibia, but the rib osteochondroma was reported less commonly. In this report, scapular snapping syndrome complicated by adventitious bursa and soft tissue pseudotumor surrounding the osteochondroma of the 6th rib body was treated successfully by surgical excision of them. We report this rare case with reviewing the relevant literature.

One of the complication during or after subclavian vein cannulation is intravascular catheter or wire embolization. Although some studies have reported safety of retaining foreign body embolization, and even death. The intravascular foreign body can be removed surgically or non-surgically. With improvement in instrument technology and technique, percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. Commonly used methods to remove intravascular foreign bodies are loop snare and basket technique. Sometimes biopy forcep can be used. We have experienced 2 cases of non-surgical removal of intravascular foreign bodies. One of the foreign bodies was 7cm wire fragment in right atrium(RA), the other was a 50cm guide wire. We used the standard loop snare technique for removal of 7cm wire fragment in RA and stone removal basket and 3.0mm ACS PTCA balloon to remove the 50cm short guide wire.

BACKGROUND: Ezrin has been reported to be involved in the metastasis of solid tumors in both an animal model and clinical trials. However, questions remains as to whether an ezrin expression is an independent predictor of the event-free survival of liposarcoma patients. METHODS: We analyzed 85 liposarcoma patients without metastasis at the time of presentation. We performed immunohistochemistry with anti-ezrin antibody, and we analyzed the association of an ezrin expression with the clinicopathological variables and event-free survival. RESULTS: Twenty-nine patients (34.1%) showed an ezrin expression. Among the 30 low-grade liposarcoma patients, only one patient showed ezrin positivity. The patients who had an ezrin expression were found to be at a significantly increased risk for metastasis compared with the patients who had no ezrin expression (risk ratio: 3.4, 95% confidence interval: 1.3-9.1). The 10-year metastasis-free survival rate was 26.9% for the patients with an ezrin expression and 86.7% for the patients without an ezrin expression. The ezrin expression rate increased with an advanced tumor grade and stage. CONCLUSION: An ezrin expression is an independent predictor of distant metastasis for liposarcoma. Thus, ezrin has the potential to provide additional prognostic information and to be a novel target for the development of new adjuvant therapies for treating the patients who suffer from liposarcoma.

Background and Objectives: The purpose of this study was to compare the preferred gain and the National Acoustic Laboratories Nonlinear 2nd edition (NAL-NL2) gain value in Korean language hearing aid users.Subjects and Method In this retrospective study, preferred gain and NAL-NL2 gain data were obtained from 199 monaural hearing aids users who were satisfied with their hearing aid devices. The gain value data were collected from three different sound levels at various frequencies. Several factors were also evaluated to determine a potential impact on the preferred gain. Results: The preferred gain was significantly higher than the NAL-NL2 target gain (p=0.01). This difference was highest with the gain measured with a medium-level sound (65 dB) with 1 kHz tone. There was a tendency of reduced preferred gain with the increased age of the participant (p=0.049). Conclusion The results indicate that Korean hearing aid users require more gain than the NAL-NL2 target gain. Linguistic characteristics, age, degree of hearing loss, and many other factors may be implicated in this result.

Congenital arachnoid cysts are commonly located at sylvian cistern or middle cranial fossa which are usually asymptomatic and incidentally found. Posterior fossa cysts, however, are usually large when diagnosed, and symptomatic. Three cases of large posterior fossa cysts were recognized on the diagnostic MRI investigation for infantile spasm, developmental delay, and the precocious puberty. Surgical decompression of the cysts by craniectomy, cyst excision and fenestration were performed successfully in two patients with arachnoid cysts in the cerebellopontine cistern and the suprasellar, right cerebellopontine, and prepontine cisterns, but an additional cystoperitoneal shunt was needed in a case with the cyst in the quadrigemial cistern with obstructive hydrocephalus. Infantile spasm was treated with vigabatrin and pyridoxine, and the true precocious puberty was managed with LHRH analogue(Decapeptyl ).

Rosai-Dorfman disease (RDD) is an idiopathic histioproliferative disorder of lymph node and extranodal site. Bone involvement is very rare. We report a case of extranodal RDD of the tibia in 32-year old male. The patient presented with pain with no evidence of lymphadenopathy. Clinico-radiologic diagnosis was metastatic carcinoma or Langerhans cell histiocytosis, but, histopathologic examination confirmed the diagnosis with RDD. We performed curettage on the osteolytic lesion of tibia. In South Korea, there was no report about RDD of the extremity and we want to report this case with review of the literature.

A 26-year-old male undergoing thoracotomy and bleeding control received a preoperative thoracic epidural for postoperative analgesia. On the fifth postoperative day, paralysis of both lower limbs occurred and urgent magnetic resonance imaging showed massive anterior epidural hematoma. During laminectomy and decompression, platelet dysfunction was diagnosed and preoperative non-steroidal anti-inflammatory drugs medications were supposed to the cause of platelet dysfunction. After infusion of ten units of platelet concentrate, coagulopathy was improved. We should be more careful to drugs with antiplatelet effect when using regional analgesia.

PURPOSE: We analyzed the oncologic characteristics and outcome of patients with inflammatory myofibroblastic tumor of extremities. MATERIALS AND METHODS: Among the soft tissue tumor patients who were treated between 1999 and 2012, 5 patients who were pathologically confirmed as the inflammatory myofibroblastic tumor of extremities were analyzed retrospectively. RESULTS: There were 1 man and 4 women with mean age of 44 years (37-55 years). The average follow up was 34.6 months (8-87 months). All patients underwent surgical treatment. Only 1 patient had wide resection margin and remaining 4 had marginal (3) or intralesional (1) resection margin. All of 4 patients without wide resection margin developed local recurrence at 10.3 months (8-19 months). Malignant transformation to fibrosarcoma was occurred in 2 patients who developed local recurrence, and 1 patient developed multiple metastases to lung, liver and lymph nodes and expired at 37 months. Three of 5 patients had tumor location abutted to or invasion to major arteries and 1 patient had tumor invading sciatic nerve. CONCLUSION: It is observed that inflammatory myofibroblastic tumor of extremities is usually located near the major neurovascular structure. Wide resection should be considered as the initial surgical treatment because this tumor showed a high local recurrence rate and possibility of malignant transformation.

BACKGROUND: The aim of this study was to estimate the minimum effective volume (MEV) of 1.5% mepivacaine for ultrasound-guided supraclavicular block by placing the needle near the lower trunk of brachial plexus and multiple injections. METHODS: Thirty patients undergoing forearm and hand surgery received ultrasound-guided supraclavicular block with 1.5% mepivacaine. The initial volume of local anesthetic injected was 24 ml, and local anesthetic volume for the next patient was determined by the response of the previous patient. The next patient received a 3 ml higher volume in the case of the failure of the previous case. If the previous block was successful, the next volume was 3 ml lower. MEV was estimated by the Dixon and Massey up and down method. MEV in 95, 90, and 50% of patients (MEV95, MEV90, and MEV50) were calculated using probit transformation and logistic regression. RESULTS: MEV95 of 1.5% mepivacaine was 17 ml (95% confidence interval [CI], 13-42 ml), MEV90 was 15 ml (95% CI, 12-34 ml), and MEV50 was 9 ml (95% CI, 4-12 ml). Twelve patients had a failed block. Three patients received general anesthesia. Nine patients could undergo surgery with sedation only. Only one patient showed hemi-diaphragmatic paresis. CONCLUSIONS: MEV95 was 17 ml, MEV90 was 15 ml, and MEV50 was 9 ml. However, needle location near the lower trunk of brachial plexus and multiple injections should be performed.
