Nowadays, inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, is increasing; however, infectious colitis, such as amebic colitis, is decreasing, so many doctors are not apt to be interested in infectious colitis. In addition, recently amebic colitis has been relatively rare in Korea, and the colonoscopic and the pathologic findings of amebic colitis are very similar to those of other inflammatory bowel diseases. As a consequence, the diagnosis is very difficult if the cyst or the trophozoite of the ameba is not found in the stool examination or in the tissue pathology. The authors experienced three cases in which initial diagnoses of tuberculous colitis, ulcerative colitis, and a simple ulcer were made based on colonoscopic and X-ray findings. However a colonoscopic biopsy revealed a trophozoite form of ameba in the tissue. Hence, a diagnosis of amebic colitis could be made with confidence. Based on these results, we insist that infectious colitis should be included in the differential diagnosis when making a diagnosis of inflammatory bowel disease. In addition, it is extremely important to consider all kinds of infectious colitis, such as amebic colitis.

PURPOSE: We studied enhanced method to view the vessels in the brain using Magnetic Resonance Angiography (MRA). Noticing that Maximum Intensity Projection (MIP) image is often used to evaluate the arteries of the neck and brain, we propose a new method for view brain vessels to stereo image in 3D space with more superior and more correct compared with conventional method. MATERIALS AND METHODS: We use 3T Siemens Tim Trio MRI scanner with 4 channel head coil and get a 3D MRA brain data by fixing volunteers head and radiating Phase Contrast pulse sequence. MRA brain data is 3D rotated according to the view angle of each eyes. Optimal view angle (projection angle) is determined by the distance between eye and center of the data. Newly acquired MRA data are projected along with the projection line and display only the highest values. Each left and right view MIP image is integrated through anaglyph imaging method and optimal stereoscopic MIP image is acquired. RESULTS: Result image shows that proposed method let enable to view MIP image at any direction of MRA data that is impossible to the conventional method. Moreover, considering disparity and distance from viewer to center of MRA data at spherical coordinates, we can get more realistic stereo image. In conclusion, we can get optimal stereoscopic images according to the position that viewers want to see and distance between viewer and MRA data. CONCLUSION: Proposed method overcome problems of conventional method that shows only specific projected image (z-axis projection) and give optimal depth information by converting mono MIP image to stereoscopic image considering viewers position. And can display any view of MRA data at spherical coordinates. If the optimization algorithm and parallel processing is applied, it may give useful medical information for diagnosis and treatment planning in real-time.

Vestibular rehabilitation therapy (VRT) is an exercise-based treatment program designed to promote vestibular adaptation and substitution. The goals of VRT are 1) to enhance gaze stability, 2) to enhance postural stability, 3) to improve vertigo, and 4) to improve activities of daily living. VRT facilitates vestibular recovery mechanisms: vestibular adaptation, substitution by the other eye-movement systems, substitution by vision, somatosensory cues, other postural strategies, and habituation. The key exercises for VRT are head-eye movements with various body postures and activities, and maintaining balance with a reduced support base with various orientations of the head and trunk, while performing various upper-extremity tasks, repeating the movements provoking vertigo, and exposing patients gradually to various sensory and motor environments. VRT is indicated for any stable but poorly compensated vestibular lesion, regardless of the patient's age, the cause, and symptom duration and intensity. Vestibular suppressants, visual and somatosensory deprivation, immobilization, old age, concurrent central lesions, and long recovery from symptoms, but there is no difference in the final outcome. As long as exercises are performed several times every day, even brief periods of exercise are sufficient to facilitate vestibular recovery. Here the authors review the mechanisms and the key exercises for each of the VRT goals.

Acquired port-wine stain is rare. It mimics a congenital port-wine stain morphologically but the pattern of onset is acquired after birth. It represents a progressive ectasia of vessels located in the superficial vascular plexus. The exact mechanism is unknown but some reported cases have occurred after trauma. We herein report five cases of acquired port-wine stains and they were idiopathic in nature.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.

Femoral Head fracture associated with posterior dislocation of the hip was once considered a rare industrial injury. However, the advant of high-speed travel has contributed to its increased incidence. Ten cases of fractured femoral head with posterior dislocation of the hip were treated at the Busan Paik Hospital between June 1979 and June 1982. During the same period, a total of 38 posterior hip dislocations were treated. The patients were followed for the average of 19.3 months, the range being 6 months to 3 years. There were 9 men and 1 woman the age ranged from 25 to 56 years. The fractures were classified according to Pipkin and the results were evaluated by Epsteins criteria. 1. The incidence of femoral head fracture was 26.3%, 10 cases of 38 posterior hip dislocations. 2. The better result was noted in open method than in closed method. 3. The absolute surgical indications were considered as followings. a. inadequate closed reduction of head fragment especially the large one. b. the involvement of weight bearing portion of femoral head. c. the hip joint pain caused by impingement of small fragment between joint space. 4. Arthrogram was helpful to find the concealed small fragment when the hip joint pain persisted with negative findings in ordinary x-ray.

Fractures of the humeral neck are relatively common, but their anatomical complexities make closed reduction difficult sometimes, and in case of reduction it is tough to maintain the position. Even open reduction of the fracture also faces multiple problems including poor functional recovery of the shoulder joint. The Department of Orthopedic Surgery of Seoul Adventist Hospital developed a device of external fixation for 13 humeral neck fractures. We used this method for displaced and unstable fractures of humeral neck from December 1987 to March 1989. Satisfactory results were obtained in 11 cases and poor results in 2 cases. We think our method is a effective useful way of treatment for humeral neck fractures, and its main advantages are as follows:1. Using proximal and distal bars, fracture can be easily reduced and firmly maintained. 2. Active motion exercise can be started early and functional recovery of the shoulder joint can be highly predictable. 3. It is quite convenient for treating combined fracture or external wound of same extremity.
