BACKGROUND: In anemic patients, it has been usually traditional practice to correct the anemic state with preoperative blood transfusion. But now, there is an increasing tendency of refusing blood transfusion due to the transfusional complications, especially AIDS etc. The purpose of this study is to survey the effects of anesthesia in anemic patients with normal cardiopulmonary function compared to non-anemics. METHOD: 40 patients with uterine myoma were divided into two groups, an experimental group of 20 patients with hemoglobin concentration of 8~10 gm% and a control group of 20 patients with hemoglobin concentration higher than 10 gm%, and their blood pressure, pulse rate and arterial oxygen saturation were monitored and compared. RESULTS: There were no significant differences between two groups in blood pressure, pulse rate and arterial oxygen saturation. CONCLUSION: Preoperative blood transfusion, in patients with moderate anemia, does not seem to be a mandatory practice.

Many authors reported the etiology of hypoplasia of the nasomaxillary complex as trauma, infection, underdevelopment. To correct these deformities, Le Fort II Osteotomy and its modification has been popularly applied. This method enabled total advancement of nasomaxillary complexes and acquirememt of midfacial esthetics. But it has some limitations such as various occlusal deviation or lateral shifting of nasomaxillary complex in case of nasomaxillary retrusion. We grouped these patients as follows : 1. Nasomaxillary retrusion without shifting of nasomaxillary complex (1) Anteroposterior deviation of occlusal plane (2) Lateral deviation of occlusal plane(including canting) (3) Supero-inferior deviation of occlusal plane (4) Combined disturbance of occlusal plane without shifting of nasamaxillary complex 2. Lateral shifting of nasomaxillary complex with or without deviation of occlusal plane We performed Le Fort II and I combined osteotomy on eleven cases of midfacial deformity from June 1994 to July 1997 and in most of the cases, followed up maximum 36 months and could acquire positional stability and improvement of facial eathetics.

To analyse the age of onset, etiologic microorganisms, clinical manifestations, managements and genetic variation of chromic granulomatous disease, the authors reviewed four patients who were diagnosed as CGD at Department of Pediatrics, Seoul National Univesity Children's Hospital. They were siblings in relationship-two of them were brothers, the others were brother-sister. @ES The results were as follows; 1) Initial manifestations developed within 1 year old, and lymphadenopathy associated with BCG vaccination was the most common. 2) In culture study of micro-organism, catalase positive microorganisms such as Staphylococcus aureus, Serratia marcescens, Coagulase (-) Staphylococcus, Enterococcus, Proleus vulgaris, Klebsiella pneumoniae, E. coli and fungus such as Candida albicans were isolated. In 2 cases, culture study revealed no growth. 3) Fever, lymphadenopathy, hepatomegaly, suppurative dermatitis and pneumonia were the most common manifestations. In most of cases, antituberculous medications were administered under the impression of tuberculosis without response. 4) Immunologic screening tests including B-cell system, T-cell system, and complement system were within normal limit except NBT test. 5) In spite of severe infections, NBT scores of all the cases were less than those of controls. Liver biopsies of 3 cases showed granuloma formation with characteristic yellow brown pigment-laden macrophages.

This study compared the microshear bond strength (microSBS) to end and side of enamel rod bonded by four adhesives including two total etch adhesives and two self-etch adhesives. Crown segments of extracted human molars were cut mesiodistally. The outer buccal or lingual surface was used as specimens cutting the ends of enamel rods, and inner slabs used as specimens cutting the sides of enamel rods. They were assigned to four groups by used adhesives: Group 1 (All-Bond 2), Group 2 (Single Bond), Group 3 (Tyrian SPE/One-Step Plus), Group 4 (Adper Prompt L-Pop). After each adhesive was applied to enamel surface, three composite cylinders were adhered to it of each specimen using Tygon tube. After storage in distilled water for 24 hours, the bonded specimens were subjected to microSBS testing with a crosshead speed of 1 mm/minute. The results of this study were as follows; 1. The microSBS of Group 2 (16.50 +/- 2.31 MPa) and Group 4 (15.83 +/- 2.33 MPa) to the end of enamel prism was significantly higher than that of Group 1 (11.93 +/- 2.25 MPa) and Group 3 (11.97 +/- 2.05 MPa) (p < 0.05). 2. The microSBS of Group 2 (13.43 +/- 2.93 MPa) to the side of enamel prism was significantly higher than that of Group 1 (8.64 +/- 1.53 MPa), Group 3 (9.69 +/- 1.80 MPa), and Group 4 (10.56 +/- 1.75 MPa) (p < 0.05). 3. The mean microSBS to the end of enamel rod was significantly higher than that to the side of enamel rod in all group (p < 0.05).

Temporomandibular disorders arised from joint itself was caused by inflammation or mechanical irritation of the retrodiskal tissues. Histologic changes of the retrodiskal tissues of temporomandibular joint(TMJ) internal derangement, such as inflammatory cell infiltration, hyalinization, myxoid change, fatty change, arterial obliteration, and so on, were reported, but relationships between magnetic resonance imaging(MRI) findings and histologic findings of the retrodiskal tissue were few reported. The purpose of this study was to find histologic changes of the retrodiskal tissues for status of joint and joint effusion in MRI of the temporomandibular joint which had surgical treatment. Materials were surgically treated 52 temporomandibular joints with internal derangement or osteoarthritis in TMJ clinic, Yongdong Severance Hospital. All joints were confirmed by magnetic resonance T1-and T2-weighted imagings bofere surgery. Status of joint was categorized by normal position, disc displacement with reduction, disc displacement without reduction, disc displacement without reduction associated with osteoarthrosis using preoperative MR T1-weighted images. Magnetic resonance evidence of joint effusion was observed in T2-weighted images and classified by its amount; degree 0(not observed), degree 1(small amount), degree 2(moderate amount), degree 3(large amount). Histologic features were observed whether the retrodiskal tissue has inflammatory cell infiltration, myxoid change, hyalinization, chondroid metaplasia and arterial obliteration. The distribution of elastic fibers were also observed. The results were as follows; 1. Inflammatory cell infiltration was not observed in any retrodiskal tissues. 2. MRI findings such as status of joint and evidence of joint effusion did not have significant relationship with myxoid change, hyalinization, chondroid metaplasia, arterial obliteration of the retrodiskal tissues. 3. Hyalinization and chondroid metaplasia were found in 8 joints(15.4%) and 5 joints(9.6%). All of them were found in disc displacement without reduction and disc displacement without reduction associated with osteoarthrosis. 4. Arterial obliteration was observed more frequently in disc displacement without reduction(55.6%) than disc displacement without reduction associated with osteoarthrosis(28.6%). Further studies with proper controls and more materials will be necessary.
