OBJECTIVE: The aim of this study was to determine the relationship between the status of a unilateral palatally impacted maxillary canine (as seen on the panoramic radiograph) and the orthodontic treatment duration. METHODS: A total of 36 subjects were chosen (8 males and 28 females, 13.7 +/- 2.5 years). All patients had undergone orthodontic traction of the impacted canine after a closed flap surgery. The position of impacted canine on the panoramic radiograph was traced and calculated with regard to the treatment duration. RESULTS: The canine overlap over the lateral incisor (COGr) had significant statistical difference between the short-term and the long-term treatment duration groups (divided by average treatment time of 21 months) (p < 0.05). Multiple regression indicated that the variables of significance (with treatment duration as the dependent variable) were the canine vertical height from the occlusal plane (HCV, r(2) = 0.115; p < 0.05) and the mandibular anterior width (MnDW, r(2) = 0.142; p < 0.05). The treatment duration, the canine angle to the incisor midline (CA), and HCV decreased from primary dentition (under 12 yrs) to permanent dentition (15 yrs). Howerer, these increased again at the adolescent ages (over 16 yrs). CONCLUSION: These findings suggested that orthodontic treatment of a palatally impacted canine would show good prognosis at an age of early permanent dentition with the canine showing smaller CA and HCV.

Experinece in the management of 74 patients with delayed traumatic intracranial hemorrhage(DTICH) of 474 head injury from January 1996 to December 1996 is poresented with emphasis on the incidence, occurring time, risk factors and outcome. The incidence of DTICH was 15.6% of all hospitalized head-injury patients. After an injury, every patient had an immediate computerized tomography(CT) scan to diagnose intracranial pathology and then CT follow-up was carried out according to intial CT finding and reurological deficit. The lesion was almost occurred in patients with initial abnormal CT finding(85.1%). 82.4% of DTICH were noted within 72 hours after injury. The delayed epidural hematoma and intracerebral hemorrhage were almost noted in first 72 hours(>90%), but the delayed subdural hemorrhage was found after a time interval varying from 6 hours to 10 days. So we strongly recommend CT follow-up in 4-8hour, 24-72hour, and then 7th day after head injury, especially in patients with initial abnormal CT findings. The risk factor of the delayed lesion was not hypotension, hypoxia, and consciousness level, but age of patients and the initial CT finding. The development of DTICH was not heralded by neurological deterioration. The prognosis of DTICH was not worse than non-DTICH. The patient with delayed subdural hemorrhage was better than the patient with non-delayed lesion(including hemorrhage and normal CT finding).

A three-year-old female beaver (Castor canadensis) was referred to the Veterinary Teaching Hospital of Chungbuk National University. It had been raised in the Cheong-ju zoo and had a history of malocclusion caused by improper feeding. General anesthesia was induced, and preoperative intraoral dental radiographs of the rostal maxillary and mandibular dentition were taken and lateral and ventrodorsal extraoral radiographs of the cheek teeth were also taken. The radiographs were negative for apical pathology and revealed a normal appearance of the cheek teeth. The lesion was likely to be related to the excessive length of the maxillary and mandibular incisors. Odontoplasty was performed to reduce overgrowth of the crowns of the incisors. Sequential transverse sections were removed until the crown was reduced by approximately its original length. The pulp chamber was not approached during the operation, as confirmed by postoperative intraoral radiographic evaluation of the incisors. Recovery from anesthesia was uneventful and the beaver returned to normal masticatory activities immediately after the operation.

Sleep Apnea Syndrome is characterized by hypersomnolence, snoring, and sleep apnea. The symptoms of hypothyroidism include apathy, somnolence, lethargy, personality change, and intellectual deterioration and may be related to hypothyroid-related sleep disorders. Central, obstructive, and mixed patterns of sleep apnea may be observed in hypothyroidism. A 60-yr-old man was admitted due to hypersomnolence, snoring and generalized edema. Polysomnogram showed obstructive pattern of sleep apnea syndrome. Neck CT scan revealed narrowing of upper airway which is consistent with obstructive sleep apnea syndrome. Physical examination and hormonal study also disclosed the evidence of hypothyroidism. We report a case of sleep apnea syndrome due to primary hypothyroidism with review of literatures.

Patients who have extruded anterior teeth and deep bite with pathologic tooth migration, it is necessary not only periodontal treat-ment for reduce inflammation, but also orthodontic treatment for intrusion of anterior teeth. However, it is difficult to place the orthodontic brackets due to the deep bite, and there is a problem that the extrusion of the posterior teeth occurs more easily than the intrusion of the anterior teeth biomechanically. In particular, in patients with long face, relative intrusion of the anterior teeth by extrusion of the posterior teeth causes the clockwise rotation of the mandible and makes the facial profile worse. Therefore the biomechanical consideration and appliance design that can block these problems are required from the treatment plan. This is a patient who had a deep overbite with extruded anterior teeth, treated by treatment and intrusion of mandibular anterior teeth using cute brackes and miniscrews, and resulted in favorable maintenance during 8-year retention.

PURPOSE: The purpose of this study was to suggest a multimodal diagnostic approach to determine the cause of the disease in patients diagnosed with synovitis of the wrist and who underwent synovectomy. MATERIALS AND METHODS: Twenty-nine patients, who underwent contrast magnetic resonance imaging (MRI) preoperatively and synovectomy from January 2000 to December 2013, were reviewed retrospectively. Among them, 17 patients underwent a Tc99m white blood cell (WBC) scan preoperatively. In patients who met the diagnostic criteria of rheumatoid arthritis (RA), the diagnosis was confirmed as RA if the MRI finding or histology was compatible with RA. If the MRI finding and histology were disparate, the final diagnosis was made based on the histologic finding. RESULTS: Of the nine patients who met the diagnostic criteria of RA, seven patients were finally diagnosed as RA and two patients as tuberculous arthritis. Of the 20 patients who did not meet the diagnostic criteria of RA, the MRI findings and histology were consistent with the same disease in 12 patients. In the remaining eight patients, five were diagnosed with nonspecific chronic synovitis, one with RA, and two with tuberculous arthritis based on the clinical findings, MRI, and histology findings. CONCLUSION: MRI and a WBC scan are very useful imaging modalities for diagnosing the causative condition of the wrist synovitis. A histology evaluation after synovectomy can also be useful in cases with a difficult diagnosis or are refractory to medications.

Osteoporosis is the most common generalized skeletal disease, which lays a significant socioeconomic burden to Korea. The early diagnosis and treatment of osteoporosis are of the great interest to minimize the economic co nsequence. We have studied vertebral BMD and bone scan of 30 patients with osteoporotic compression fractures. The purpose of this study was to investigate the effect of osteoporotic compression fracture on bone mineral density(BMD). We have measured the vertebral heights, vertebral bone mineral density, and bone scan counts of vertebral bodies on osteoporotic patients. Vertebral BMD was measured from T12 to L4 using dual photon absorptiometry. Anterior(Ha), middle(Hm), and posterior(Hp) height of vertebrae were measured from T12 to L4, and the spinal deformity indices(Ha/Hp, Hm/Hp, and Hp/Hi ratios) were calculated. The bone scan counts were measured from T12 to L4, and bone scan ratios were calculated. The BMD of fractured vertebrae was significantly higher than that of non-fractured vertebrae The spinal deformity indices were not correlated to the BMD of fractured vertebrae. The bone scan ratio was correlated to the BMD of fractured vertebrae. This study suggests that the increased BMD observed in fractured vertebrae is related to metabolic effect of compression fractures rather than mechanical effect.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma of late adult life, but it is rare in the pleura. We recently experienced a case of cytology of malignant fibrous histiocytoma in pleural fluid. The smear revealed histiocytic malignant cells, spindle malignant cells and inflammatory cells. The histiocytic cells showed abundant, pale cytoplasm and ovoid, irregular, eccentrically placed nuclei. The spindle cells showed elongated nuclei. Intercellular collagen was also present.
