PURPOSE: MOPP/ABV hybrid regimen incorporates MOPP and ABVD into a single regimen on the tenets of the Goldie-Coldman hypothesis. This study was performed to determine the efficacy of COPP/ABV hybrid regimen, in which cyclophosphamide was substituted for mechlorethamine, in patients with advanced Hodgkin's disease. MATERIALS AND METHODS: Patients with advanced Hodgkin's disease were treated with cyclophosphamide(600 mg/m2 iv, Dl), vincristine(1.4 mg/m2 iv, D1), procarbazine(100 mg/m2/d po, D1-7), prednisolone(40 mg/m2/d po D1-14), doxorubicin(35 mg/m2 iv, D8), bleomycin(10 mg/m2 iv, D8) and vinblastine(6 mg/m2 iv, D8). The treatment was repeated every 4 weeks. RESULTS: Between Aug. 1989 and Aug. 1996, 28 patients were enrolled. The median age was 33 years. Twenty one(75%) were previously untreated, newly diagnosed patients and 7(25%) were those who had relapsed after previous radiotherapy(RT). The common histologic types were nodular sclerosis(46%) and mixed cellularity(36%). Twenty three (82%) patients achieved complete remission(CR), three(11%) with the assistance of involved-field RT. Only one patient was primary treatment failure. The median follow-up duration was 56 months. Of the 23 patients achieving CR, three(13%) relapsed. Five-year relapse-free survival was 84.4%. Eight patients died. Five-year overall survival rate was 66.6% and 5-year failure-free survival rate was 66.3%. The survival rate of those who had relapsed after previous RT was significantly lower than that of newly diagnosed patients(P=0.03). The hematologic toxicities were common, but nonhernatologic toxicities were uncommon. Five patients died of treatment-related pneumonia or sepsis. Among them, four were those who had relapsed after previous RT. CONCLUSION: COPP/ABV hybrid regimen could cure significant proportion of patients with advanced Hodgkin's disease but the treatment-related mortality was high, especially in those who had relapsed after previous RT. Another regimen should be considered for those who received previous RT.

Ameloblastoma is a common odontogenic tumor originating from the dental lamina, reduced dental epithelium and rests of Malassez, and represents 10% of all odontogenic tumors of the jaw. Unicystic ameloblastoma is normally encountered in young patients, and often occurs in the mandible, and is particularly associated with an impacted tooth. We encountered an unicystic ameloblastoma arising from a dentigerous cyst after the treatment of a radiolucent lesion on the mandible.

We report two patients of generalized nonconvulsive status epilepticus (GNSE) accompanied by end-stage renal disease. Both patients were presented with impaired responsiveness and behavioral abnormalities. Continuous generalized epileptiform discharges were noted on EEG. GNSEs of our patients were responsive to benzodiazepines clinically and electroencephalographically. And they were controlled by short-term antiepileptic treatment and improvement of uremic condition. (J Korean Neurol Assoc 19(5):533~536, 2001)

PURPOSE: Peripheral T-cell lymphomas(PTCL) show diverse clinical and histological characteristics and should be understood as mixtures of heterogeneous entities. Although many clinical and biological parameters have been proposed for classifying PTCL into different prognostic groups, few parameters have turned out to be appropriate for classification. To investigate the clinical significance of FUO presentation in PTCL, comparisons of clinical parameters were performed using non-FUO presentation as a control. MATERIALS AND METHODS: 66 cases of Korean PTCL were divided into FUO group and non-FUO group according to the presentation and compared with each other. RESULTS: Among 66 patients of PTCL, 19 patients presented with FUO. Compared with non-FUO group, FUO group showed no significant age and sex ratio differences. FUO group showed more advanced stage, worse performance status than non-FUO group. Predominant sites of definite diagnosis were skin, gastrointestinal tract and liver in FUO group and nasal cavity and paranasal sinus in non-FUO group. There were no significant differences between histologic classifications of both groups. Survival analysis revealed significant differences between both groups. FUO group showed significantly shorter survival. Prognostic factor analysis(multivariate) was done with stage, LDH level, performance status, and FUO status. FUO status, stage and performance status were significant determinants of survival, but LDH level proved to have no prognostic implication. CONCLUSION: PTCL with FUO presentation showed such distinct characteristics that the authors propose fever of unknown origin(FUO) as a clinical parameter for classifying PTCL. Further studies are needed to identify biological parameters which characterize PTCL with FUO presentation.

The purpose of this study was to investigate the clinical, biomechanical, and histologic changes in new distraction osteogenesis (DO) technique combined with a compression stimulation in accordance to different compression-distraction force ratio. 23 adult male rabbits underwent open-osteotomy at the mandibular body area and a external distraction device was applied. In the control group of 8 rabbits, only a 8 mm of distraction was performed by conventional DO technique. In an experimental group of 15 rabbits, a distraction followed by a compression force was performed according to the ratio of compression-distraction suggested by authors. The rate of experimental group I was set up as a 2 mm compression versus 10 mm distraction and the rate of experimental group II was set up as a 3 mm compression versus 11 mm distraction. All the rabbits were sacrificed for a gross finding, biomechanical, histomorphometric and histologic findings at the time of 55 days from the operation day. The results were as follows: 1. On the gross findings, because all rabbits had a sufficient healing time, every distracted new bone had good bone quality and we could not find any difference among all three groups. 2. In the histologic findings, rapid bone maturation (wide lamellar bone formation in the cancellous and cortical bone areas) was observed in two experimental groups compared to the control group. 3. On the bone density tests, the experimental group II showed higher bone density than the other experimental group and control group (control group - 0,2906 g/cm2, experimental group I - 0.2961 g/cm2, experimental group II - 0.3328 g/cm2). 4. On the biomechanical tests, the experimental group II had significantly higher bone microhardness than the other experimental group and control group (control group - 252.7 MPa, experimental group I - 263.5 MPa, experimental group II - 426.0 MPa). 5. On the microhardness tests, when we compared the hardness ratio of distracted bone versus normal bone, we could find experimental group II had significantly higher hardness ratio than the other experimental group and control group (control group - 0.47, experimental group I - 0.575, experimental group II - 0.80). From this study, we could deduce that the modified distraction osteogenesis method with a compression stimulation might improve the quality of bone regeneration and shorten the consolidation period in comparison with conventional distraction osteogenesis techniques.

Aspegillosis is a fatal opportunistic disease using immunosupppresive drugs after liver transplantation. Mortality of aspergillosis after liver transplantation reaches 100% and survival rate pulmonary aspergillosis is less than 5% using medical treatment only and pneumonectomy and medical treatment revealed better results. We experienced the invasive pulmonary aspergillosis developed a patient who suffered from bacterial pneumonia and had long peroid of mechanical ventillation after liver transplantation. We performed pneumonectomy and antifungal medical treatment for about 50 days and he recovered from invasive aspergillosis.

Lateral medullary infarction can lead to central respiratory failure. However, in Wallenberg's syndrome, obstructive respiratory failure rarely develops. Here, we report a case of obstructive respiratory failure with stridor caused by unilateral lateral medullary infarction. A 74-year-old woman was admitted for acute right lateral medullary infarction. On the 12th day after the stroke, the patient developed respiratory failure necessitating endotracheal intubation. She could maintain good oxygen saturation and ventilation in intubated status without the assistance of mechanical ventilator, even during sleep. The pharyngo-laryngoscopy demonstrated the hypomobility of bilateral vocal cords. This case suggests that unilateral medullary infarction might be a cause of bilateral vocal cord palsy.

PURPOSE: To evaluate antitumor response, time to progression, and toxicities of oxaliplatin, 5- fluorouracil (5-FU), and leucovorin (LV) continuous infusion in patients with metastatic colorectal cancer who progressed during or after treatment with a 5-FU-containing regimen. MATERIALS AND METHODS: Forty-eight patients with metastatic colorectal cancer, who progressed while receiving or after discontinuing palliative chemotherapy with 5- FU-based regimen, were enrolled in this study. Treatment consisted of oxaliplatin (85 mg/m2 on day 1) as a 2-hour infusion followed by bolus 5-FU (400 mg/m2 on day 1), and 5-FU 48-hour infusion 2.4~3 g/m2 concurrently with LV 48-hour infusion 150 mg/m2, without mixing. Cycles were repeated at 2-week intervals. The dose of 5-FU was modified, depending on the hematologic toxicity profile. RESULTS: The objective response rate was 28% for 43 assessable patients (95% confidence interval, 14% to 42%), including one complete remission (2%). Seventeen additional patients (39%) had stable disease, and fourteen (33%) progressed. The median time to progression was 5.9 months and the median overall survival was 13.2 months from the start of the chemotherapy. From the 297 cycles analyzed, hematologic toxicities per course were: leukopenia; grade I 26.6%, grade II 3.4%, and grade III 0.3%, thrombocytopenia; grade I 10.8%, grade II 3.0%, grade III 1.0%, and grade IV 0.3%. The most frequent nonhematologic adverse reactions were nausea/vomiting and peripheral neuropathy, which were rated as WHO grade II in 13 patients (49%) and 11 patients (22%), respectively. CONCLUSION: This phase II study of oxaliplatin, 5-FU, and LV continuous infusion showed enhanced antitumor activity in patients with 5-FU-pretreated metastatic colorectal cancer. Overall toxicity was acceptable; neurotoxicity and bone marrow suppression constituted the dose-limiting side effects.

OBJECTIVE: To evaluate the value of apparent diffusion coefficient (ADC) histogram analysis for predicting tumor recurrence in patients with uterine cervical cancer treated with chemoradiation therapy (CRT). MATERIALS AND METHODS: Our institutional review board approved this retrospective study and waived informed consent from each patient. Forty-two patients (mean age, 56 +/- 14 years) with biopsy-proven uterine cervical squamous cell carcinoma who underwent both pre-treatment pelvic magnetic resonance imaging with a 3.0 T magnetic resonance scanner and concurrent CRT were included. All patients were followed-up for more than 6 months (mean, 36.4 +/- 11.9 months; range 9.0-52.8 months) after completion of CRT. Baseline ADC parameters (mean ADC, 25th percentile, 50th percentile, and 75th percentile ADC values) of tumors were calculated and compared between the recurrence and no recurrence groups. RESULTS: In the recurrence group, the mean ADC and 75th percentile ADC values of tumors were significantly higher than those of the no recurrence group (p = 0.043 and p = 0.008, respectively). In multivariate analysis, the 75th percentile ADC value of tumors was a significant predictor for tumor recurrence (p = 0.009; hazard ratio, 1.319). When the cut-off value of the 75th percentile ADC (0.936 x 10-3 mm2/sec) was used, the overall recurrence free survival rate above the cut-off value was significantly lower than that below the cut-off value (51.9% vs. 91.7%, p = 0.003, log-rank test). CONCLUSION: Pre-CRT ADC histogram analysis may serve as a biomarker for predicting tumor recurrence in patients with uterine cervical cancer treated with CRT.
