PURPOSE: To evaluate MR characteristics of periosteal reactions and subperiosteal abscesses in osteomyelitis as compared with radiographs. MATERIALS AND METHODS: We retrospectively reviewed 28 patients(18 males, 10 females) with osteomyelitis. Nineteen patients underwent MR imaging with 0.5 T. We analyzed for morphologic patterns, intervals of appearance and disappearance of periosteal reactions after symptom onset. Twenty-three patients were confirmed by surgery and 5 patients by the radiologic findings, clinical and laboratory data. RESULTS: Periosteal reaction appeared as low signal intensity arc on the T1- and T2-weighted axial images. In 3-7 days after symptom onset, periosteal reactions and subperiosteal abscesses were noted on MR imaging, and only two of eleven patients were noted in radiographs. Periosteal reactions of 8-14 days after symptom onset were demonstrated in all of 13 patient on MR, and 9 on plain radiographs. All patients with 2 weeks after symptom onset showed perioste.al reaction in plain film and MR. The periosteal reactions persisted until approximately 2 to 3 months after treatment on follow up radiographs. CONCLUSION: Periosteal reactions in osteomyelitis are detected on the MR imaging earlier than plain film. MR is valuable in detecting subperiosteal abscess which is not appecent in simple radiographs. Periosteal reactions can be seen on MR in 3 days after symptom onset and persist for 2-3 months after treatment.

Pre-surgical and post-surgical change in adult clef lip and palate patient following Le Fort I advancement osteotomy combined with bone graft was evaluated clinically and cephalometically. We obtained a successful function and esthetic improvement. The bone graft of alveolo-palatal clefts provides a stable bone support to the adjacent teeth of the cleft area, and well union of adjacent bone tissue, the closure of oronasal fistula and improvement of speech problem. Le Fort I osteotomy following the ostectomy of nasal septum for advancement of the maxilla was obtained relative improvement of esthetics and functional occlusion. 1. The orthodontic correction was required before and after surgery. 2. In this case, there was a limited range of anterior advancement of the Premaxillary-segment due to the scar tissue. 3. After 8 months of operation, we could show the new bone deposition on the cleft sites in dental radiograph and then the prosthetic treatment to the missing teeth was done.

PURPOSE: To evaluate the usefulness of spiral CT in predicting the depth of tumor invasion in patients with gastric cancer by comparing with histopathological finding. MATERIALS AND METHODS: We studied spiral CT scans of forty-eight patients, in whom gastric cancer was proven by gastrofibroscopic biopsy and surgery. After distending the stomach with 400ml tap water or effervescent granules, 100ml of contrast media was given intravenously at a rate of 3ml/sec. CT scanning was started at 45 sec after administration of the contrast material. Gastric tumors were subdivided into five types according to enhancing pattern from the inner layer of gastric wall to the outer layer. These pattern were correlated with histopathologic results. RESULT: The tumor masses were detected on CT scan in 10(77%) of 13 patients with early gastric cancer, while, the tumor masses were seen on CT scan in all patients with advanced gastric cancer. Of 9 patients with type 1 or type 2 enhancing pattern, early gastric cancer(T1) were proven in 7 patients(78%), serosal invasion (T3) in 2 patients(22%). In contrast, among 29 patients with type 4 and type 5, 22 patients(76%) were proven as serosal invasion(T3). Of 7 patients with type 3, 3 patients(43%) were proven as serosal invasion(T3), three(43%) as subserosal invasion(T2), one as early gastric cancer(T1). CONCLUSION: Analysis of morphological enhancing pattern on spiral CT is useful in predicting the depth of tumor invasion in patients with gastric cancer.

Actinomycosis still poses a problem for correct clinical and radiologic diagnosis. We retrospectively analyzed CT findings in 7 patients with pathologically proven abdominal actinomycosis. Involved areas were the pelvis (n=3), greater omentum (n=2), liver (n=1), and kidney (n=1). CT confirmed the infiltrative nature of the disease with a tendency to invade across tissue plane and boundary. Five of seven cases were predominantly solid mass (pseudotumor) with focal low-attenuation areas while two were predominantly cystic mass with thickened wall. Contrast-enhanced CT showed dense, inhomogeneous contrast enhancement in the wall and/ or solid components of the masses in five. Minimal lymphadenopathy was noted in one case. CT is useful in demonstrating the extent and characteristics of this disease. Despite nonspecific findings, actinomycosis should be included in the differential consideration when CT shows an infiltrative mass with unusual aggressiveness and dense inhomogeneous contrast enhancement in patients with fever, leukocytosis, or long-term use of intrauterine contraceptive devices.

This study examined the behavioral change and memory impairment following transient forebrain ischemia in 20 male rats: ten rats were subjected to sham operation. Inchemia was induced by a combination of bilateral common carotid artery occlusion and induced hypotension. During the recovery period, behavioral change was evaluated by open-field method. Histopathological examination was performed 7 days after ischemic insult. The results were as follows 1) Hippocampus CA 1 neuron was the most vulnerable to 10-minute forebrain ischemia. 2) There was increase in locomotor activity and rearing during early post-ischemic period. 3) Ischemia resulted in suppressed preening and grooming. From the above mentioned results, authors suggested that transient forebrain ischemia produced severe neuronal damage in CA l sector of hippocampus, therefore produced behavioral change and memory impairment.

PURPOSE: Kabuki syndrome is a rare syndrome of multiple congenital anomalies and mental retardation, which is characterized by a peculiar face resembles Kabuki actor, postnatal growth retardation, and skeletal abnormalities. The ocular feature such as strabismus, amblyopia, ptosis, blue sclera and long palpebral fissure with eversion of the lateral portion of lower eyelid can be seen in this syndrome. We experienced a Kabuki syndrome patient with ocular feature. CASE SUMMARY: A 6 years old girl visited ophthalmology department for frequent blinking, abnormal movement of eyelid. She showed growth retardation, high palate arch, bifid uvula and low hairline. Best corrected visual acuity was 0.5 in the right eye and 0.4 in the left eye. She also presented with mixed astigmatism (right: +sph 1.00;-cyl 3.00 Ax 180, left: +sph 1.00;-cyl 3.50 Ax 180). In addition, Marcus-Gunn jaw winking in her left eye and a long palpebral fissure were noted. She had intermittent exotropia and a tilted optic disc in the left eye.

PURPOSE: To evaluate the ultrasonographic features of nonlactiferous breast abscess. MATERIALS AND METHODS: We retrospectively reviewed ultrasonograms of 21 cases with surgically and clinically proved nonlactiferous breast abscess. The cases included 17 cases of acute or chronic inflammation and 4 cases of tuberculosis. RESULTS: Location of the lesion was subareolar in 15 cases and peripheral in 6. Mean anteroposterior/transverse diameter ratio was 0.49. Internal echogenicitiy of the lesion was variable, with heterogeneous mixed-echoic echotexture in 18 cases and homogeneous hypoechoic in 3. Margin of the lesion was irregular in 18 cases(85.7%) and posterior sonic enhancement was observed in 17 cases(81%). There were also noted obliteration of adjacent superficial fascia, localized skin thickening, and sinus tract or ductal ectasia in 19(90.5%), 9 (42.9%), and 9(42.9%) cases respectively. CONCLUSION: Major ultrasonographic findings of nonlactiferous breast abscess was subareolar located, variable shaped mass with posterior enhancement. Additional findings were fistular formation, loss of superficial fascia, and axillary lymphadenopathy.
