Pedicled bone flap raised from the volar aspect of lower end of the radius, pedicled by the pronator quadratus has been used for the treatment of scaphoid nonunion and Kienbock's disease. From July 1991 to Jan. 1992, authors performed this procedures for 3 cases of Kienbock's disease. Patients were 2 cases in the left hand, l case in the right hand. There was no critial trauma history. Age at operation were 25, 37 and 57 years. All patients were in Stage I in 2 cases and stage II-A in 1 case of Lichtman's radiologic classification. Preoperative grip powers were 11%, 38%, 63% and pinch powers were 20%, 41%, 61% of that of normal opposite hand. Follow up periods were 28, 31 and 33 months. At last follow up roentgenographic finding shows no progression of necrosis of lunate, new bone formation, decreased sclerosis, and joint space were preserved in all cases. The fuctional results at the last follow up were as follows. Pain during motion was markedly diminished in all patients. Grip power were 57%, 89% and 96% and pinch powers were 68%, 83% and 100% of that of normal opposite hand with use of calibrated Jamar dynamometer which showes significant increase than preoperative state. The ranges of motion of wrist were as follows. Volar flexion were 40, 45 and 80 degree. Dorsiflexion were 10, 20 and 45 degree. Ulnar deviation were 10, 20 and 30 degree. Radial deviation were 10, 25 and 30 degree. This viable bone graft with blood supply gives very satisfactory clinical results.

Teratoma is one of germ cell tumor, common neoplasm in women of reproductive age, but it can arise at any age. Its malignant transformation is rare, less than 2%, frequently at older age. Nearly all the cases are squamous, sarcomatous and adenomatous transformation. Here we present a case of mixed transformation, adeno-squamous cell carcinoma with brief review of the concerned literature.

OBJECTIVES: This study aims to compare home care dental devices for their dental plaque removal ability. METHODS: A single blinded randomized crossover clinical study design was used to measure plaque index (Turesky Modification Quigley-Hein Plaque Index). RESULTS: All 3 groups showed a statistically significant decrease in the plaque index after usage (P<0.001). In manual tooth-brushing group, the teeth on the right dental arch showed a greater decrease in the plaque index than on the left arch (P=0.041). All appliances showed greater plaque reduction in the upper right posterior teeth than in the lower right posterior teeth (P=0.009, 0.004, 0.007). CONCLUSIONS: The results of this study support development of more effective oral hygiene appliances and emphasis on oral hygienic education.

The present study examines the effects of orthodontic treatment of surgically exposed impacted upper canines or ectopically erupted upper canines to periodontal condition and whether various opening procedures have significant difference in postoperative periodontal status. The subjects included 23 orthodontic patients(7 men, 16 women) with unilateral upper canine impaction treated either with closed eruption technique(group I), with apically positioned flap procedure(group II), and those with canines ectopically erupted through keratinized gingiva(group III). In each subject, the ectopic canine was orthodontically aligned, and changes in periodontal tissue were assessed by measuring keratinized gingival width, attached gingival width, probing depth and bone probing depth. In all three groups, the width of keratinized gingiva was preserved while showed no signs of detrimental periodontal condition such as gingival recession. In all three groups, no significant difference in periodontal pocket depth from control was observed. The width of attached gingiva was significantly greater in patients treated with apically positioned flap procedure(group II) than in patients on other groups.

PURPOSE: The purpose of this study was to evaluate the bond strengths between the latest CAD/CAM ceramic inlay and various resin cements which are used primarily for esthetic restoration. MATERIALS AND METHODS: Cylindrical ceramic blocks(Height: 5 mm, diameter: 3 mm) were fabricated by using Cerec3 and bonded on the dentin of the ninety extracted caries-free molars using three different kinds of resin cement(Unicem(R), Biscem(R), and Variolink II(R)) according to the manufacturer's instructions. Ninety specimens were divided into 3 groups according to three different kinds of resin cement. Half of each group were conducted thermocycling under the conditions of the 5 - 55degrees C, 5,000 cycle but the other half of them weren't. All specimens were kept in normal saline 37degrees C, for 24 hours before measuring the bond strength. The shear bond strength was measured by Universal testing machine with a cross head speed of 0.5 mm/min. The results were analyzed statistically by t-test and one-way ANOVA. RESULTS: Unicem(R) group showed the highest shear bond strength despite a slight decline by thermocycling. The shear bond strength of Unicem(R) group and ValiolinkII(R) group were significantly influenced by thermocycling, whereas Biscem(R) group was not influenced (P<.05). There were no significant differences in the bond strength between the three groups without thermocycling, but there was significant differences between Unicem(R) group and Valiolink II(R) group with thermocycling(P<.05). CONCLUSION: It has been shown to be clinically effective when the self-adhesive resin cements Unicem(R) and Biscem(R) were used instead of the etch-and-rinse resin cement Valiolink II(R) during the bonding of CAD/CAM ceramic inlay restorations with teeth.

Fruiting bodies of Phellinus linteus were extracted by hot water and alkali methods. Sugar contents of PL-H (hot water extract) and PL-A (alkali water extract) were 81.1%, 37.4% and protein contents were 6.2%, 21.8%, respectively. Amino acid pattern showed that two extracts contained large amount of aspartic acid and alanine. Two extracts showed characteristic IR absorption pattern for glycosidic bond at 890 cm(-1). PL-H was divided two fractions by gel filtration chromatography and the molecular weights of each fraction were estimated to be about 10 kD and 225 kD, respectively and also PL-A was estimated 10 kD. Two extracts showed strong antitumor, immunomodulating and antioxidant activities, and were compared with commercialized glycopeptide anticancer drugs.

Sporadic calcification of the left atrium is frequently observed in patients with long standing rheumatic valvular heart disease. However, massive calcification involving the entire left atrium, the so-called porcelain or coconut atrium, is extremely rare. A case of recurrent thrombosis in the left atrium was experienced due to massive calcification of the left atrial wall, despite the therapeutic anticoagulant level of the patient following a surgical thrombectomy.

Trichosporonosis is a potentially life-threatening infection with Trichosporon beigelii, the causative agent of white piedra. The systemic infection by this fungus has been most frequently described in immunocompromised hosts with neutropenia. Here, we report the first patient with disseminated infection by T. beigelii in Korea, acquired during a period of severe neutropenia after chemo-therapy for myelodysplastic syndrome. The patient recovered from the infection after an early-intensified treatment with amphotericin B and a rapid neutrophil recovery. The disseminated infection by T. beigelii is still rare, however, is an emerging fatal mycosis in immunocompromised patients with severe neutropenia.

Dyskinesia hyperpyrexia syndrome is a rare medical emergency in Parkinson's disease. It is characterized by continuous dyskinesia associated with hyperthermia, rhabdomyolysis, and alteration of the mental state. We present the case of a 74-year-old woman who presented with recurrent dyskinesia hyperpyrexia syndrome. Although some provocation factors and clinical manifestations seem to be shared with parkinsonism hyperpyrexia syndrome, a clear distinction in management should be considered.

We report a case of an Epstein-Barr virus (EBV)-associated inflammatory pseudotumor-like follicular dendritic cell tumor (IPT-like FDC tumor). The tumor occurred in the spleen of a 64-year-old woman with a history of a diffuse large B-cell lymphoma (DLBCL) of neck nodes that presented four years ago. The splenectomy specimen revealed a 5 cm-sized, tan-colored and well-circumscribed mass. Histologically, spindle or ovoid cells with large vesicular nuclei were admixed with abundant inflammatory cells. Immunohistochemically, spindle cells were positive for FDC marker CD35, but negative for CD20, CD30 and ALK. EBV was detected almost exclusively in spindle cells by EBER in situ hybridization. IPT-like FDC tumors are rare, and are recognized as a distinctive clinicopathologic variant of FDC tumors. Among only 18 similar cases reported in the English language literature, the present case is the first case of a patient with a history of DLBCL.
