The present report presents a case of dens invaginatus (DI) in a patient with 4 maxillary incisors. A 24-year-old female complained of swelling of the maxillary left anterior region and discoloration of the maxillary left anterior tooth. The maxillary left lateral incisor (tooth #22) showed pulp necrosis and a chronic apical abscess, and a periapical X-ray demonstrated DI on bilateral maxillary central and lateral incisors. All teeth responded to a vitality test, except tooth #22. The anatomic form of tooth #22 was similar to that of tooth #12, and both teeth had lingual pits. In addition, panoramic and periapical X-rays demonstrated root canal calcification, such as pulp stones, in the maxillary canines, first and second premolars, and the mandibular incisors, canines, and first premolars bilaterally. The patient underwent root canal treatment of tooth #22 and non-vital tooth bleaching. After a temporary filling material was removed, the invaginated mass was removed using ultrasonic tips under an operating microscope. The working length was established, and the root canal was enlarged up to #50 apical size and obturated with gutta-percha and AH 26 sealer using the continuous wave of condensation technique. Finally, non-vital bleaching was performed, and the access cavity was filled with composite resin.

PURPOSE: The aim of this study is to develop and apply the critical pathway to the orbital wall fracture patients and to elucidate its effect. METHODS: Critical pathway(CP) sheet and questionnaire were developed by a team approach. Critical pathway was applied to 7 orbital wall fracture patients (CP group) from April 2006 to September 2006. Length of hospitalization and cost for hospitalization of CP group were compared to those of the 10 patients who had same disease entities and treated by conventional regimen(control group). RESULTS: Length of hospitalization in the CP group (7.20 day) were insignificantly shorter than that of control group(8.71 day). Mean cost for hospitalization of the CP group(776,398 won) were insignificantly lower than that of control group(1,028,531 won). The patients satisfaction for the explanation regarding operation procedure, therapeutic operation fee, length of hospitalization and medical personnel were all affirmative. CONCLUSION: Critical pathway that we developed for orbital wall fracture definitely improved the quality of treatment. Furthermore, other critical pathways should be developed for another facial trauma patients.

Subepidermal calcified nodule, a form of calcinosis cutis, usually occurs as a solitary lesion and develops in early childhood. We report a 20-month-old boy with an unusual form of subepidermal calcified nodules on both palms and soles which were multiple and present at birth. Interestingly, his uncle had similar lesions during infancy which had shown spontaneous remission.

Percutaneous needle biopsy of pulmonary lesion with use of fluoroscopic guidance is well estabilished as a diagnostic tool but limited by the small size and inaccessibility of certain lesions. However, percutaneous needle biopsy'has been used increasingly in relation to advance and the salty of smaller biopsy needle and new imaging modalities such as ultrasound and CT. CT, because of its characteristics of high resolution, allows tissue sampling with considerable safty from area that heretofore could not be visualized under fluoroscopy. The authors summarized 44 pulmonary lesions that underwent CT-guided transthoracic biopsy with fine-needle over a 14 month period and analyzed the sensitivity of PTNB. -CT-guided PTNB was done with 20 gauge or 22 gauge Westcott biopoy needle (Mann medical products, USA). A diagnosis was made in 27 of 44 cases (61%) including malignany in 19 of 24 cases and benignancy in 8 of 20 cases. The pulmonary mass lesions were located at the peripheral zone of the lung field in 33 cases and at the central zone in 11 cases. Complications were observed in 2 cases which were pneumothorax and hemoptysis each but specific therapy was not required The sensitivity of PTNB by one session was 61% (27/44). The sensitivity of malignancy was 79% (19/24) and benignancy was 40% (8/20). These results suggest the usefulness of PTNB using fine needles be increased in eariler diagnosis and improved staging of pulmonary nodular lesions without significant complications.

The fibromatosis is a rare timorous with local invasion, but is not metastasized distantly. This term should not be applied to nonspecific reactive fibrous proliferations that are part of an inflammatory process of are secondary to injury of hemorrhage and have no tendency toward growth or recurrence. It arises principally from the connective tissue of muscle and overlying fascia or aponeurosis (musculoaponeurotic fibromatosis), and chiefly affects the muscle of shoulder, pelvic girdle, and extremity. The term 'aggressive fibromatosis' is also employed to describe this disease, but it is impossible to predict the clinical course in the individual case. The fibromatosis arising in the mediastinum is very rare, and the report about it is nearly absent. The plain radiography shows merely mass with soft tissue density. The CT demonstrates a poorly defined homogenous or heterogeneous mass, isodense with skeletal muscle on precontrast-images, and slightly hyperdense to muscle on postcontrast-scan. Accurate delineation between the tumor & surrounding tissue is vague or frequently impossible. The authors experienced one case of the mediastinal fibromatosis recently and report the case with review of concerned literature.

PURPOSE: Alterations in cerebral blood flow are very important for understanding the neurological consequences of all varieties of perinatal asphyxia. The purpose of this study is to measure the change of cerebral blood flow velocity and resistance index (RI) of middle cerebral artery (MCA) according to the time in asphyxiated infants. METHODS: We studied 7 asphyxiated term infant and 27 normal term infant who were born at Ewha Womans University Hospital from January 1996 to August 1997. Using the Doppler ultrasound, we examined blood flow velocity and RI of the middle cerebral artery. RESULTS: Clinical characteristics were not significantly different in both groups. Peak systolic flow velocity (PSFV) in asphyxiated infants significantly decreased than control (P<0.05). End diastolic flow velocity (EDFV) was not significantly different in both groups. RI in asphyxiated infants significantly decreased for 24 hours (P<0.05). No control infant ever had a RI value of 0.55 or below, three (42.9%) asphyxiated infants had a RI value of 0.55 or below. The changes of the systemic BP and heart rate were not significant. Two (28.6%) asphyxiated infants were proven periventricular white matter ischemia by ultrasonography. CONCLUSION: It is therefore very important to monitor RI in asphyxiated infants even if the degree of asphyxia is mild.
