Reversible splenial lesion syndrome can be caused by viral infection. Rubella generally occurs in
childhood, and it is rarely accompanied by neurological complications in adulthood. A 35-year-old man
visited our hospital due to conjunctival injection, mild fever, and headache 3 days after experiencing
skin rash. Brain magnetic resonance imaging (MRI) revealed distinct lesions involving white matter in
the splenium of the corpus callosum approximately 3 days following the onset of symptoms. Enzyme
immunoassay performed on serum and CSF samples was positive for rubella virus IgM. A follow-up
brain MRI was performed 24 days after the onset of symptoms, and reduced lesion size with decreased
signals were observed on diffusion weighted image. This case showed that rubella infection can result
in reversible splenial lesion accompanied by only mild neurological symptoms.

BACKGROUND: Selecting the appropriate patients and reducing stroke onset to endovascular recanalization therapy (ERT) time are essential elements of a successful ERT. Since ERT is available only in large hospitals, proper patients transfer is important. The purpose of study is to examine the suitability of the transfer of acute stroke patients. METHODS: We retrospectively reviewed the medical records of patients who diagnosed as acute ischemic stroke from January to December in 2017. Patients were divided into two groups based on transfer (direct visit vs. transfer) and Alberta Stroke Program Early computed tomography (ASPECT) score (≥8 vs. <8) respectively. Each group was assessed by demographics, type and rate of reperfusion therapy, onset to reperfusion therapy time, stroke risk factors and neurological deficit severity. Interhospital distance and transfer time was calculated in transferred patients. RESULTS: Among the 455 patients, the 228 (50.2%) patients underwent interhospital transfer. The ratio of reperfusion therapy was not significant different between direct visit and transferred group (34.8% vs. 37.3%, p=0.397). The transferred patients tended to be older (p=0.003), female (p=0.001), more hypertension (p=0.019), less transient ischemic attack (p=0.001), longer onset to ERT time (178.55±85.92 vs. 131.48±82.89; p=0.001) lower ASPECT score (6.72±2.04 vs. 8.01±1.65; p<0.001) and higher National Institute of Health Stroke Scale (NIHSS) (p<0.001) and modified Rankin Scale (mRS) (p<0.001). High ASPECT score (≥8) patients were more direct visited (63.9%), shorter onset to ERT time (p=0.047), lower initial NIHSS and mRS (p<0.001), and greater in differences between mRS at admission and 3 months later (p=0.016). CONCLUSIONS: This study suggests emergency and interhospital transfer of acute stroke patients is inefficient, and systematization of transfer is necessary.

This dealt with the 23 cases of giant cell tumor of femur and tibia who were treated with curettage and cementation of the lesion, over 14 year period. Cement by virtue of it's heat of polymerization may “sterilize” the wall upto 3-5mm in depth. Authors adoped cement treatment as an effective adjuvant after intra-lesional surgery(curettage). Curettage was indicated in all stage I lesions; most stage 2 and some stage 3 lesions, provided the residual bone stock were sufficient to make it oncologically and mechanically effective. The follow-up period ranged from 3 to 14 years(oaverage 8 years and 6 months). The sites of the lesions were proximal tibia in 8, dital femur in 13, proximal femur in one, and distal tibia in one. Among these cases, 3(13.0%) cases(two grade 1 and one grade 2) of stage II(To: active), and 2(8.7%) of stage III(grade 2) (Tl or T2: aggressive). Utmost attention was paid to nulify or to reduce the local seeding of the tumor cell during aggressive curettage, which was followed by electrical cautery of the cavitey wall, and lastly by the cavity obliteration with bone cement. None of the cases had lung metastasis. Only in a stage III GCT case(4.3%) of local recurrence after curettage and bone and artificial bone graft, recurettage and cementation brought the successful outcome. Through this study, it was reconfirmed that with correct indications the use of cement as a local adjuvant in conjuction with curettage was effective method in treating GCT without any side effects.

Peripheral nerve injury occurs mostly in company with tendon and muscle injuries, fractures, or dislocations. Because of the disabilities and socioeconomic loss caused by such injuries, much attention must be paid to the initial treatment, and later to the reconstruction and rehabilitation. At department of Orthopedic Surgery, Seoul National University Hospital, 336 patients of nerve lesion were treated from Jan, 1980 to Dec, 1988. Among them 128 patients were nerve compression syndrome (carpal tunnel 52 patients, cubital tunnel 40 patients, thoracic outlet 16 patients, others 20 patients), and 50 patients were brachial plexus injury, and 168 cases were peripheral nerve injury. 50 patients of the peripheral nerve injury were treated with reconstruction and 118 patients were treatred with neurorrhaphy, nerve graft, and neurolysis. Of the 118 patients, 94 patients were followed up for more than one year, and the results of neurorrhaphy, nerve graft and neurolysis were analyzed. In 46 patients (73.0%) of the patients treated with neurorrhaphy, 7 patients (58.3%) with nerve graft, and 15 patients (78.9%) with neurolysis, good or excellent results were obtained.

Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in the synovial membrane, periarticular structures, skeletal muscle and perineural sheath. Eventually, the joints are destroyed, ankylosed and deformed. Therfore, the aim of treatment is to keep the inflammatory process at a minimum, thereby preserving the joint motion, maintaining the health of muscle supplying motor power about the joint and preventing secondary joint stiffness and deformity. Surgical treatment in rheumatoid arthritis has progressed and there have been advances in the relief of pain and increase in the range of motion. Among them the results of total knee arthroplasty (TKA) have improved steadily during the past decade due to refinements in design, fixation, and surgical technique. At orthopedic department of seoul national university hospital, we performed 31 total knee replacement in 18 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1988. Following results were obtained. 1. Knee score increased from 37.8 to 76.9. 2. Tibio-femoral angle was corrected from 0.9° valgus to 5.3° valgus. 3. Conplications were peroneal nerve palsy in 3 knees, instability in 1 knee, tuberculous arthritis in 1 knee. 4. In 25 out of 31 knees, good functional results were obtained.

The methanol extract from the leaves of Petasites japonicus Maxim (PJ) was studied for its (anti-)mutagenic effect with the SOS chromotest and reverse mutation assay. The (anti-)carcinogenic effects were evaluated by the cytotoxicity on human cancer line cells and by the function and the expression of gap junctions in rat liver epithelial cell. PJ extracts significantly decreased spontaneous beta-galactosidase activity and beta-galactosidase activity induced by a mutagen, ICR, in Salmonella (S.) typhimurium TA 1535/pSK 1002. All doses of the extract (0.08-100 mg/plate) decreased the reversion frequency induced by benzo (alpha)pyrene (BaP) in S. typhimurium TA 98. It decreased not only the spontaneous reversion frequency but also that induced by BaP in S. typhimurium TA 100. PJ extract showed greater cytotoxic effects on human stomach, colon and uterus cancer cells than on other cancer cell types and normal rat liver epithelial cells. Dye transfers though gap junctions were significantly increased by PJ extracts at concentrations greater than 200 microg/mL and the inhibition of dye transfer by 12-O-tetradecanoylphorobol-13-acetate (TPA) was obstructed in all concentrations of PJ. PJ significantly increased the numbers of gap junction protein connexin 43, and increased the protein expression decreased by TPA in a dose-dependent manner. Based on these findings, PJ is suggested to contain antimutagenic and anticarcionogenic compounds.

We performed dual color fluorescence in situ hybridization (FISH) for the bcr/abl fusion in CML using the peripheral blood smears without destruction of cell morphology to determine the bcr/abl fusion. Two patients of CML, one patient in accelerated phase and one patient in chronic phase, were selected. The blood smears were fixed in absolute methanol. FISH was performed with the Mbcr/abl translocation DNA probe mixture and the slides were stained with Wright's stain after FISH. The blood smears of both cases revealed distinct signals without destruction of cellular morphology. The normoblasts and lymphocytes revealed beautiful fused bcr/abl signals as well as granulocytes in both cases. The results provide a novel finding that the normoblasts and lymphocytes in CML are also neoplastic clonal cells which has not been demonstrated with a single-cell approach before.
