Inflammatory myofibroblastic (IMF) tumor is a rare solid tumor that often affects children. IMF tumors occur primarily in the lung, but the tumor may affect any organ system with protean manifestations. A 22-year-old woman was evaluated for palpable low abdominal mass that had been increasing in size since two months prior. Abdominal computed tomography showed a lobulated, heterogeneous contrast enhancing soft tissue mass, 6.5 x 5.7 cm in size in the ileal mesentery. At surgery, the mass originated from the greater omentum laying in the pelvic cavity and was completely excised without tumor spillage. Histologically, the mass was a spindle cell lesion with severe atypism and some mitosis. Immunohistochemistry for anaplastic lymphoma kinase-1 revealed that the lesion was an IMF tumor. Because of its local invasiveness and its tendency to recur, this tumor can be confused with a soft tissue sarcoma. Increasing physician awareness of this entity should facilitate recognition of its clinical characteristics and laboratory findings.

OBJECTIVE: Our aim was to compare the compression quality, exercise intensity, and energy expenditure in 5-minute single-rescuer cardiopulmonary resuscitation (CPR) using 15:1 or 30:2 compression-to-ventilation (C:V) ratios or chest compression only (CCO). METHODS: This was a randomized, crossover manikin study. Medical students were randomized to perform either type of CPR and do the others with intervals of at least 1 day. We measured compression quality, ratings of perceived exertion (RPE) score, heart rate, maximal oxygen uptake, and energy expenditure during CPR. RESULTS: Forty-seven students were recruited. Mean compression rates did not differ between the 3 groups. However, the mean percentage of adequate compressions in the CCO group was significantly lower than that of the 15:1 or 30:2 group (31.2±30.3% vs. 55.1±37.5% vs. 54.0±36.9%, respectively; P<0.001) and the difference occurred within the first minute. The RPE score in each minute and heart rate change in the CCO group was significantly higher than those of the C:V ratio groups. There was no significant difference in maximal oxygen uptake between the 3 groups. Energy expenditure in the CCO group was relatively lower than that of the 2 C:V ratio groups. CONCLUSION: CPR using a 15:1 C:V ratio may provide a compression quality and exercise intensity comparable to those obtained using a 30:2 C:V ratio. An earlier decrease in compression quality and increase in RPE and heart rate could be produced by CCO CPR compared with 15:1 or 30:2 C:V ratios with relatively lower oxygen uptake and energy expenditure.

The concept of biostimulation of wounds by low-level laser therapy (LLLT) is attracting considerable attention. Although its effect on whole tissues has been studied quite extensively, the biological and cellular mechanisms underlying LLLT have not been clarified. In an experimental radius fracture in rabbits, Tang and Chai reported that LLLT enhanced the activity of red blood cells, macrophages, fibroblasts, chondrocytes, and osteoclasts within the fracture area. The purpose of the present study was to evaluate the effect of LLLT with a GaAlAs diode laser device on bone healing in rabbit mandibular fractures. We use 12 rabbits for this study. All rabbits were fractured mandible angle area using saw in anesthetic condition. In control group(n=6), none treatment was performed at fracture site. In experimental group(n=6), LLLT with a GaAlAs diode laser was radiated at fracture site daily for 7 days. All rabbits were sacrificed at 6 weeks later from performed fracture day. We studied the immunohistochemical staining of CD34 and Vimentin and the histochemical analysis for calcium and phosphorus content. The results were as follows. 1. In the histological and immunohistological staining, after 6week, fibroblasts, osteogenic cells and collgen fibers were observed more in experimental group than in control group. 2. In the histochemical analysis, the amount of calcium and phosphorus contents of the experimental group were more than the control group. From the results obtained, we suggest that the bone healing is stimulated by low-level laser irradiation in bone fractures.

OBJECTIVE: To assess the effects of partial weight bearing (PWB) harness with comparison of traditional exercise program by gait analysis in non-ambulatory acute stroke patients. METHOD: Nine patients participated with PWB harness on the treadmill, and nine patients with traditional exercise. In harness group, the gait training with 30% weight reduction was offered on treadmill, they were treated daily and gait training was done for 20 minutes. In no-harness group, traditional gait training was done by physical therapists. Variables were gait parameters assessed by VICON 370 Gait Analyzer, other function tested by Motricity Index and Functional Ambulatory Category. RESULTS: In linear parameter, the harness group had faster gait speed, longer stride length, and more decreased double support time compared to the no-harness group. In kinematic parameters, the maximal flexion of knee was significantly increased in harness group, but no significant differences was in hip and ankle motion. In kinetic parameters, hip flexion moment of normal side was increased in harness group at heel strike phase, knee flexion moment of normal side was decreased in harness group at heel strike phase. CONCLUSION: The gait training with partial weight bearing harness was more effective in acute stroke patients than traditional therapy, and was influenced in gait pattern, functional ability.

The purpose of this study was to compare the apical microleakage in root canal filled with Resilon by several self-etching primers and methacrylate-based root canal sealer. Seventy single-rooted human teeth were used in this study. The canals were instrumented by a crown-down manner with Gate-Glidden drills and .04 Taper Profile to ISO #40. The teeth were randomly divided into four experimental groups of 15 teeth each according to root canal filling material and self-etching primers and two control groups (positive and negative) of 5 teeth each as follows: group 1 - gutta percha and AH26(R) sealer; group 2 - Resilon, RealSeal(TM) primer and RealSeal(TM) sealer; group 3 - Resilon, Clearfil SE Bond(R) primer and RealSeal(TM) sealer group 4 - Resilon, AdheSe(R) primer and RealSeal(TM) sealer. Apical leakage was measured by a maximum length of linear dye penetration of roots sectioned longitudinally by diamond disk. Statistical analysis was performed using the One-way ANOVA followed by Scheffe's test. There were no statistical differences in the mean apical dye penetration among the groups 2, 3 and 4 of self-etching primers. And group 1, 2 and 3 had also no statistical difference in apical dye penetration. But, there was statistical difference between group 1 and 4 (p < 0.05). The group 1 showed the least dye penetration. According to the results of this study, Resilon with self-etching primer was not sealed root canal better than gutta precha with AH26(R) at sealing root canals. And there was no significant difference in apical leakage among the three self-etching primers.

It is common in childhood that children suffer intracavity or head injury, falling down backward, having chopsticks in their mouth. But most of them have paralysis of upper and lower extremity because of secondary damage by penetrating injury of brainstem and spine. We could not find this case which have shown infaction of medulla oblangata on MRI and paralysis by impact only without clear penetrating evidence. So the authors report this case with study of literature because we experience one case that have high signal density in brainstem on MRI, Loss of consciousness, and left hemiplegia without clear penetrating evidence after falling down backward, having chopsticks in her mouth and regard it rare case.

PURPOSE: The purpose of this study was comparing the efficacy of passive irrigation (PI) and passive ultrasonic irrigation (PUI) for ability to remove debriment of canals. MATERIALS AND METHODS: Mandibular premolars were decoronated and standardized to 16 mm length. After root canal enlargement and half separating longitudinally, standardized groove of 4 mm length, 0.2 mm width and 0.5 mm depth were formed on the dentin wall of one half. Three depressions in the canal wall of the opposite half, 0.3 mm in diameter and 0.5 mm in depth, were formed. After each groove and depression was filled with dentin debris, two sections of each half were reassembled using impression putty material. In group 1 the canals were irrigated with 2.5% NaOCl by PI. In group 2 the canals were irrigated with 2.5% NaOCl by PUI. Before and after root canal irrigation, the root canal wall of the section was taken with a microscope and a digital camera as images. The amount of dentin debris remaining in grooves and depressions was assessed using a scoring system. RESULTS: There was no significant difference between PI and PUI except for the middle 1/3 of the root canal (P = 0.004). CONCLUSION: At the middle 1/3 of the root canal, PUI removed more dentine debris than PI. But the removal efficiency of dentin debris is not significantly different between the PUI and PI at the apical area of root canal in mandibular premolars.

OBJECTIVES: The anthors examined health-seeking behavior about using herbal medicine in psyciatric and other clinical patients. The effect, side effect and motives in selecting herbal medicine were examined also. This study aimed at presenting treatment guide for psychiatric patients hereafter. METHOD: Subjects were consisted of 277 patients who were 93 medical, 81 surgical, and 102 psyhiatric patients. We made a questionnaire checking circumstances on taking herbal medicine. The investigating psychiatrist conducted person to person semi-structured interview using this questionnaire. RESULTS: Psychiatric patients preferred herbal medicine to western medicine, as other clinical patients did. In their health seeking behavior, classical illness model of oriental herbal medicine occupied a central position. In addition, psychiatric patients not only regarded herbal medicine as a more symtom-specific therapeutic medication, but also accepted side effects of herbal medicine uncritically than other clinical patients. CONCLUSIONS: As it is known that many psychiatric patients take both oriental and western medical treatment, we should not have exclusive attitude to emphasize one side between oriental and western medicine. Rather, we should deepen our understandings about oriental herbal medicine.

OBJECTIVE: Detection of intracranial multiple aneurysms, including mirror-image aneurysms, have recently been increasing with the development of diagnostic techniques. However, studies of mirror-image aneurysms have been rare in South Korea. Thus, we intend to report our hospital's experience with mirror-image aneurysms during the past 20 years along with a review of relevant literature. METHODS: We analyzed medical records and image data from patients with cerebral aneurysms who had been admitted to our institution from January 1988 to June 2007. We divided the patients into three groups and investigated the clinical patterns of mirror-image aneurysms (Group 1). We then compared them with patients exhibiting non-mirror multiple aneurysms (Group 2) and the patients with solitary aneurysms (Group 3). We also statistically analyzed the age, sex, smoking habits, medical histories, and prognoses of the patients. RESULTS: Mirror-image aneurysms were found in 62 (5.1%) of the 1,209 patients admitted for cerebral aneurysms over the past 20 years. Of the mirror-image aneurysms, 48% were located in the posterior communicating artery (PcoA), and 40% were in the middle cerebral artery (MCA). Ruptures of aneurysms occurred slightly more frequently on the right side and when the aneurysm was larger and its shape was more irregular. Women, particularly menopausal women aged 50 and older, were shown to be at higher risk. Smoking was also a risk factor. However, there were no significant differences in prognoses among the three groups. CONCLUSION: We should pay attention to the possibility of mirror-image or multiple aneurysms when diagnosing and treating menopausal women and smokers, particularly if the cerebral aneurysm is located in the MCA or PcoA.

Spontaneous rupture of an ovarian artery aneurysm is an extremely rare, life-threatening disease and has been reported to be most highly associated with pregnancy. The current study presents a case of intraperitoneal and retroperitoneal hematoma caused by spontaneous rupture of a right ovarian artery aneurysm in a 56-year-old woman. A 56-year-old woman visited the emergency room with right lower quadrant abdominal pain. Contrast-enhanced computed tomography showed a large retroperitoneal and intraperitoneal hematoma and active extravasation of contrast medium in the right retroperitoneum. Consequently, transcatheter arterial embolization was successfully performed. Spontaneous rupture of an ovarian artery aneurysm should be suspected in multiparous women with abdominal or flank pain even if it is unrelated to pregnancy. Suspicion of this entity is needed for earlier diagnosis and management.
