Hepatocellular carcinoma (HCC) with portal vein invasion has a poor prognosis. Treatments such as transarterial chemoembolization (TACE), radiation therapy (RT), sorafenib are done as a first line treatment. But in case of incomplete response to first line treatment, there's no established guideline about salvage treatment. We present a 47 year-old male who was diagnosed as HCC with portal vein invasion. He was treated with RT and repeated TACE, but remnant viable tumor was observed. Surgical resection was performed as a salvage treatment, and HCC was completely removed. He has been followed up over 3 years, but there was no recurrence.

Little literature exists about the risk of atypical femoral fracture in patients received zoledronic acid for prevention of skeletal metastasis. We report an atypical subtrochanteric femoral fracture in a patient with multiple myeloma received zoledronic acid. The patient was treated by closed reduction and internal fixation with cephalomedullary nailing.

It has been thought that autoimmune diseases like systemic lupus erythematosus and rhumatoid athritis are closely associated with anti-DNA antibodies (Abs). In studies of the control for anti-DNA Ab generation, an understanding of the regulatory mechanisms by anti-idiotypic Abs that influence the production of anti- DNA Abs would be facillitated by the availability of the hybridomas producing the pairs of DNA-specific and anti-DNA's idiotope-specific monoclonal antibodies (mAbs). We have produced a series of anti-DNA mAbs and then monoclonal anti-idiotypic Ab directed against idiotypic determinant of the 3D8 mAb that has the highest affinity to dsDNA and ssDNA among the anti-DNA mABs that we had obtained. The spleen cells of the MRL-Ipr/Ipr, autoimmune prone, mice were fused with P3X63Ag8.653 myeioma cells to obtain anti-DNA Ab secreting hybridomas. Out of the fourteen clones that showed strong binding to ssDNA, four clones had cross-reactivity with dsDNA whereas none of these clones reacted with left-handed z-DNA. The binding activities of the anti-DNA mAbs to various synthetic polynucleotide sequences were different respectively. Anti-idiotypic mAbs were generated by the fusion of myeloma cells and spleen cells from the Balb/c mice immunized with 3DB-Fab. We have produced two anti-idiotypic mAbs, B7 (IgG2a/k) and 02F3 (IgM/k), which were specific to 3DB-Fab and cloned the variable region of the heavy chain from the 02F3 hybridoma.

OBJECTIVES: This study was carried out to estimate the prevalence of isocyanate-induced occupational asthma in toluene diisocyanate (TDI) exposed workers. METHODS: We examined 170 workers who had been directly exposed to TDI through a medical questionnaire, physical examination, and pulmonary function test. Based on screening examination, workers with suspected occupational asthma were selected for further evaluation such as methacholine and TDI challenge tests. RESULTS: Eleven (6.9%) among 170 workers complained of symptoms of occupational asthma, and 7 among these 11 symptomatic workers showed positive responses to the methacholine challenge test (4.1%). One spray painter was confirmed as having the TDI induced occupational asthma following a positive response to TDI challenge test. CONCLUSIONS: The prevalence of TDI-induced asthma was at 0.58% was lower than that for former studies (2-20%). Improved workplace environment, lower level of TDI exposure compared to the past, and the healthy workers effect may have contributed to this low rate of asthma prevalence in workers with TDI exposure.
