BACKGROUND AND OBJECTIVES: The long-term effect of tinnitus retraining therapy (TRT) is excellent while its short-term effect is known to be inferior to tinnitus making (TM). In this regard, we mixed TRT (mTRT) by combining TRT and TM to improve the short-term effect of TRT. This study evaluated the short-term effect of the mTRT and also compared the clinical efficacy between mTRT and TM. SUBJECTS AND METHOD: Twenty patients who underwent mTRT due to chronic subjective tinnitus were included in this study. Sound therapy of the mTRT was performed with mixed noise of broadband noise and narrow band noise. The broadband noise was used for TRT and the narrow band noise was used for TM. During the first month of mTRT, sound therapy was mainly composed of narrow band noise. During the second month, the proportion of broadband noise was gradually increased to 2/3. After 3 months, only the broadband noise was applied. Tinnitus Handicap Inventory (THI), Visual Analog Scale (VAS) on annoyance and the tinnitus awareness duration (hr/day) was checked as the outcome measures. The outcome was also compared between mTRT and TM. RESULTS: The THI score decreased significantly from 41.8+/-24.3 to 27.3+/-25.6 after mTRT. The VAS (from 5.9+/-1.4 to 4.7+/-1.8) and the tinnitus awareness duration (from 18.5+/-8.2 to 12.6+/-10.7) also showed a significant improvement after treatment. When the treatment outcome was compared between mTRT and TM, there was no significant difference. CONCLUSION: mTRT seems to be effective in relieving the discomfort of tinnitus. Similar short-term outcomes can be expected from mTRT as they did in TM.

Buoy flap was useful method for soft tissue defect, bone defect or bone and soft tissue defect. Also the buoy flap could use monitoring for blood flow. The advantages of the buoy flap were long length of perforating cutaneous branch, large diameter of Peroneal vessel, transposition in same leg and the another advantage was that the fibula is the long, straight and mainly cortical bone. To obtain successful result of buoy flap, one must have the anatomic concept for vascular pattern (straight branch, proximal oblique branch, branch from muscular branch, distal oblique branch), relationships with surrounding muscles (between Peroneus m. and Soleus m., Through Peroneus m., through Soleus m.) and length of perforating branch. So, we studied total 19 person, 22 cases of buoy flap, who were admitted and took the operation at Kyung Hee University College hospital, from October 1985 to March 1987.

The shoulder fusion is one of the good method to relieve pain, improve the function and stabilize the flail shoulder joint. But recent advance of arthroplasty, the procedure is less popular. Authors studied and analized 23 patients who received shoulder arthrodesis from Aug. 1978 to Aug. 1986 and reported functional outcome after shoulder arthrodesis. Among twenty three patients, brachial plexus palsy were eighteen, upper extremity residual poliomyelitis in three and shoulder joint turberculosis in two respectively. Postoperative follow up was 12 months to 9 years and 6 months, average being 2 years and 6 months. It took 14.4 weeks in average for shoulder arthrodesis. The postoperative abduction fusion angle was 33.8 degrees in average(20 degrees to 50 degrees). The active abduction after shoulder fusion was mean 51.8 degrees(20 degrees to 85 degrees). The abduction fusion angle between 20 degrees and 40 degrees was presented satisfactory results in the point of pain relief, functional assessment and patients satisfaction. High abduction fusion angle(more than 40 degrees) revealed pain around the fused shoulder area. The combined extra and intraarticular arthrodesis revealed better results. The Saber-cut approach was more valuable for secondary elbow reconstruction than Henry approach.

Classic anatomical descriptions state that the common bile duct enters to the medial border of the second part of duodenum. Isolated case reports of the common bile duct in other sites, including the fourth part of duodenum, the pyloric canal, stomach, and the duodenal bulb, have appeared in the literature. We report three cases of anomalous drainage of the common bile duct into duodenal bulb, which caused recurrent cholangitis and peptic ulcer. All patients required choledochoenteric anastomosis to relieve their syrnptoms.

BACKGROUND AND OBJECTIVES: A rotation chair test has been used to evaluate the function of the horizontal semicircular canals. Currently, two chair systems according to the presence of cylindrical darkroom are used in a clinic setting. However, it has not been thoroughly investigated whether one system is superior to the other system or not. In this study, we aimed to compare test outcomes and subject convenience between two systems. SUBJECTS AND METHODS: Twenty subjects with no history of otologic disease were enrolled. Subjects were tested with two systems: system [A] with a cylindrical chamber and system [B] with no chamber. The results of sinusoidal harmonic acceleration (SHA), step velocity (SV), and visual fixation (VFX) tests were compared between the systems. Subject convenience was assessed with a questionnaire survey and results were compared between the systems. RESULTS: There were no significant differences in gain or asymmetry in SHA test between the systems. However, the phase of system [A] was significantly lower than that of system [B] at 0.16 Hz. There was no significant difference between the systems in directional preponderance (DP) gain or DP time constant. Regarding the VFX test, gain was higher in system [A] than system [B]. Subjects reported less stuffiness and less anxiety with system [B] than system [A], while preferring the system [A] goggles. CONCLUSIONS: A rotation chair system without a darkroom can provide a more comfortable experience for subjects in terms of stuffiness and anxiety, while showing comparable results in SHA and SV tests with a darkroom system.

A 77-year-old woman was admitted to this hospital for evaluation of chest pain for 3 days. On physical examination, icteric sclerae, inspiratory crackles on both lower lung field and normal heart sounds were observed. Electrocardiograms showed pathologic Q waves with ST elevations in the precordial leads(V1-V4). Chest X-rays showed mild pulmonary edema with anteroseptal wall akinesia. Cardiac enzyme studies were compatible with AMI. Hematologic investigation revealed severe thrombocytopenia and microangiopathic hemolytic anemia. Coagulation profiles were normal. Coombs test, sucrose lysis test, anti-platelet antibody and antinuclear antibody were all negative. Urinalysis showed albuminuria(+++) and microscopic hematuria. Initial therapy with aspirin, nitrate, morphine and prednisolone was started. Ten hours after admission, she developed agitation, aphagia and confusion with progression to coma. Computed tomography of the brain was normal. Five units of fresh frozen plasma were infused. After one day, platelet counts slightly increased. But cardiogenic shock ensued and she died despite cardiopulmonary resuscitation. AMI has not been reported in association with TTP. This patient had no risk factors for coronary artery disease and no previous history of angina. TTP was clinically diagnosed with confidence by excluding other known cause of microangiopathic hemolytic anemia with thrombocytopenia. Coronary angiogram and bone marrow examination could not be performed due to a rapidly fatal course. The etiology of AMI in this patient was not confirmed, but clinical evidence strongly supported etiologic association with TTP.
