One-year mortality after discharge was 18.2%. The relationship between on-treatment BP and all-cause mortality followed a reversed J-curve relationship. A nonlinear, multivariable Cox proportional hazard model identified a nadir of systolic and diastolic BPs of 132.4/74.2 mm Hg in patients, for whom the mortality rate was lowest (p < 0.0001). The relationship with increased mortality above and below the reference BP was more definitive for diastolic BP and for HF with a preserved ejection fraction.</P><P><B>Conclusions</B></P><P>Systolic and diastolic BPs <130/70 mm Hg at discharge and during follow-up was associated with worse survival in HF patients. These data suggest that the lowest BP possible might not be an optimal target for HF patients. Further studies should establish a proper BP goal in HF patients.

Adding effects of corncob and cottonseed meal for the sawdust cultivation of Lentinula edodes

For diversification of materials for sawdust cultivation of Lentinula edodes, this study was carried out to examine adding effects of corncob and cottonseed meal on sawdust cultivation. All treatments of corncob except 100% corncob have produced fruiting-bodies. Mushroom productivity of the fungus was decreased from 174g to 45g per 2kg sawdust-based substrate in proportion to increasing corncob contents in sawdust cultivation. Meanwhile, in treatments including less than 20% cottonseed meal, the mycelial growth of the fungus was similar to control. But, the other treatments were not suitable for the mycelial growth of fungus on sawdust-based substrate. All treatments of cottonseed meal did not produce the fruiting-body of the fungus.
下顎骨上行枝의 斜線骨折斷術에 依한 下顎前突症의 治驗報告

The patient, a 20-year old Korean male, had a protruding mandible. His mandibular prognathism was corrected by open oblique sliding osteotomies of the mandibular rami.

Odontomas are probably the most common of the odontogenic tumors, and have been defined as a tumor composed of dentin and enamel in which pulp and cementum also are present This is the report of a case of complex-compound odontoma occured in the right mandibular body area. The patient, 6 years-old male, was admitted to dept. of oral and maxillofacial surgery, Kyung Hee University Medical Center with the chief complaint of painless mass on the right mandibular body area. We were certained of complex-compound odontoma through clinical and radiographic feature, and then performed surgical enucleation of tumor including removal of involved teeth. Through surgical procedures and biopsy, this tumor confirmed to be a combination of complex and compound types. After 12 months follow up check, we noticed the bony replacement of operation site and no recurrence.

Myxomas are rare tumor that probably arise from the mesenchymal portion of the dental papilla, dental follicle, or periodontal membrane. This is to report a case of myxoma occurred in the left maxillary alveolar portion, maxillary sinus and pterygomaxillary fossa. The patient, 28 years-old female, was admitted to Dept, of Oral & Maxillofacial Surgery, Kyung Hee University Medical Center with the chief complaint of painless mass on the upper left molar area. In this case, the roentgenographic findings revealed sun-ray appearance, root resorption, displacement of involved tooth and destruction of lateroposterior wall of maxillary sinus. The histopathological findings revealed a soft tissue covered by hyperplastic stratified squamous epithelium with prominent rate ridge and no cellular atypia, The upper portion of underlying connective tissue is composed of fibrous collagenous tissue with numerous proliferating fibroblasts and infiltration of large numbers of chronic inflammatory cells and deep portion is made up of loosely arranged, spindle shaped and stellate cells with long fibrillar process. Conservative local curettage is the preferred treatment. Removal of the maxilla or mandible should be avoided if at all possible. Removal should be done only when pathologic fracture or extension of the tumor into the vital anatomical structures is inevitable. In this case, we performed curettagement of the tumor via intraoral approach.

This is a case report of the orthognathic surgery improved true mandibular prognathism by sagittal split ramus osteotomy with intraoral approach. The sagittal split ramus osteotomy was made on the lingual and buccal aspects and was then connected along the anterior border of the ascending ramus. After the mandible was displaced to the backward direction, direct bone wiring near the anterior border of ascending ramus was applied for stabilization. For preventing the postoperative swelling & hematoma, hemovac was inserted. There were no severe complications except postoperative swelling and edema for 2 days. Intermaxillary fixation was maintained for 8 weeks and postoperative orthodontic treatment was performed for 3 months.
顎顔面部에 發生한 軟組織疾患의 診斷時 Ultrasonography의 應用에 관한 硏究

Ultrasonography is known to provide valuable information concerning the size, nature and location of soft tissue lesions. So that It was utilized for diagnostic purposes for the ten years. It was originally utilized mainly in opthalmology and obstetrics and gynecology. But in recent years, it was very useful in diagnosis of soft tissue masses In oral and maxillofacial area. This technique is non-invasive and inexpensive, and has not radiation hazard when compared to computerized tomography. Ultrasonography is capable of differentiating not only cystic form solid lesions but also can be helpful in the diagnosis of malignant vs. benign masses. A ultrasonic study was performed in 5 patients with various soft tissue lesions in oral and maxillofacial region (cystic hygroma, intramuscular hemangioma, neurilemmoma, tuberculous lymphadenitis, abscess) using B-scan(gray scale) ultrasonography. The results are summerized below. 1. Cystic hygroma showed internal echo free pattern, enhancement of posterior detail and multiloculated well delineated oval shaped outline. 2. In intramuscular hemangioma, ultrasonography demonstrated internal echo free pattern and two posterior attenuation were made by two calified body. 3. Neurilemmoma showed homogenous internal echo pattern, and well delineated oval shaped outline. 4. In tuberculosis lymphadenitis, internal nature was not coincided with computerized tomography, but size and location were coincided with that. 5. Suppurative abscess on masseter muscle showed internal echo free pattern.
