In periodontal regeneration treatment, access to the frucation area is very difficult. Thus complete removal of plaque, calculus and endotoxin is somewhat impossible. In this study, teeth that were extracted due to periodontal disease were used. The furcation area was treated with periodontal curette, ultrasonic scaler, roto bur and they observed using SEM. The result was follows 1. The group treatment with curette showed remaining plaque, the cementum existed in most of the surface and partial dentinal tubule orifice could be seen. 2. The group treatment with ultrasonic scaler showed less removalof plaque compared to curette and irregular surface could be seen. 3. The group treatment with roto bur showed cleaner surface and many dentinal tubule orifice could be seen compared to the curette and ultrasonic scaler groups. Thus when suing treatments such as bone grafting or guided tissue regeneration, it is considered that the furcation area should be treatment with Roto bur.

A 77-year-old man developed diplopia, gait ataxia, and paresthesia. A clinical examination also revealed ophthalmoplegia, facial palsy, ataxia of the limbs and trunk, and reduced deep tender reflexes. Laboratory and electrophysiological studies revealed albuminocytological dissociation and demyelination. He was diagnosed as Miller-Fisher syndrome and received intravenous immunoglobulin therapy. His clinical symptoms deteriorated at 12 weeks after onset. We diagnosed acute-onset chronic inflammatory demyelinating polyradiculoneuropathy, and which the patient recovered from following corticosteroid therapy.

A 54-year-old Korean male with scleroderma-like manifestation of primary systemic amyloidosis presented with firm cutaneous induration of face and distal extremities, subcutaneous induration of the trunk and proximal extremities, limited range of motion in all joints, hoarseness, and dysphagia. Monthly high-dose intravenous immunoglobulin (hdIVIg) was given (three treatments, each time administering 0.4 g/kg per day for five days), and both signs and symptoms began to improve. However, the quantitative analyses of serum protein did not improve. Therapeutic plasma exchange (TPE) was performed monthly to clear the elevated serum immunoglobulin, and after several treatments, their levels normalized and symptoms were maintained in the improved state for more than two years. To summarize, hdIVIg and TPE combination therapy may be used as a safe first-line treatment for patients with primary systemic amyloidosis presenting with symptomatic monoclonal gammopathy.

BACKGROUND: Almost every study of rib fractures in the elderly show associated injuries resulting in admission to thoracic or cardiovascular surgery. In Korea, no studies have compared these elderly patients with younger patients. METHODS: This study is based on patients who were diagnosed as having rib fracture at the Emergency Department of the Seoul Medical Center from March 2013 to April 2011. The medical records and radiological examinations of 192 cases were reviewed. Two groups were created-older than 65 years and younger than 64 years. Comparisons were made between the two groups including place of injury, time of injury, associated injuries, and the final result in the Emergency Department. RESULTS: The final patient sample size was 192. The elderly group had 142 patients with the average age being 48.77+/-9.70 years and 75.4% males. The young group had 50 patients with the average age at 75.90+/-7.21 years and 25% males. The most common place of injury was road (p=0.007) in the young group and home (p=0.002) in the elderly group. The most common mechanisms of injury were slipping (47.4%), traffic accidents (18.2%), falling (14.1%), and assault (9.4%). Falling was more prevalent in the young group than in the elderly group (p=0.011). Rib fractures occurred at night (p<0.001), on Saturdays, on Sundays, and in the winter in the young group and in the morning(p=0.002), on Mondays, on Fridays, and in the winter in the elderly group. Associated injuries, in descending order, were chest, limb, head, and spine. CONCLUSION: This study found that several selected factors of an injury-place, mechanism, time, and associated injuries, differ by age.

We report a non-obese patient suffering from spastic gait and right leg paresis caused by thoracic spinal cord compression secondary to spinal epidural lipomatosis. Although spinal epidural lipomatosis is most often associated with the administration of exogenous steroid or endogenous Cushing syndrome, obesity also has been reported as a possible cause. However, idiopathic(non-glucocorticoid induced) spinal epidural lipomatosis in non-obese healthy man is an extremely rare disease and dose not have any good explanation for the abnormal fat deposition in spinal epidural space. We recently experienced a patient with idiopathic thoracic epidural lipomatosis in whom MRI and histopathology established the specific diagnosis. With a case report, brief review of the disease including clinical feature, diagnostic procedure and therapeutic considerations is described.

OSCC is currently the most common malignancy of the head and neck, affecting tens of thousands of patients per year worldwide. Natural flavonoids from plants are potential sources for novel anti-cancer drugs. Icariin is the active ingredient of flavonol glycoside, which is derived from the medical plant Herba Epimedii. A metabolite of icariin, icariside II exhibits a variety of pharmacological actions, including anti-rheumatic, anti-depressant, cardiovascular protective, and immunomodulatory functions. However, the exact mechanism causing the apoptosis-inducing effect of icariside II in OSCC is still not fully understood. In the present study, we assessed the anti-cancer effect of icariside II in OSCC cell lines by measuring its effect on cell viability, cell proliferation, and mitochondria membrane potential (MMP). Icariside II treatment of OSCC cells resulted in a dose- and time-dependent decrease in cell viability. Hoechst staining indicated apoptosis in icariside II-treated HSC cells. Icariside II inhibited cell proliferation and induced apoptosis in HSC cells, with significant increases in all present parameters in HSC-4 cells. The results clearly suggested that icariside II induced apoptosis via activation of intrinsic pathways and caspase cascades in HSC-4 cell lines. The collective findings of the study suggested that Icariside II is a potential treatment for OSCC; in addition, the data could provide a basis for the development of a novel anti-cancer strategy.
