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.

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.

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.

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.

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.

BACKGROUND: For cancer patients, pain is the most common symptom and the most important factor that seriously affects their treatment and quality of life. The purpose of the research was to determine the controllable factors for pain management in order to increase patients' satisfaction for pain management. METHOD: This study was based on the survey answers and medical records of 464 cancer patients, in 8 hospitals in Korea from March until September 2000. RESULTS: As shown by Chi-square test, according to the degree of satisfaction for cancer pain management, those patients who were "satisfied" with pain treatment showed better activity rate (P=0.007) than the "unsatisfied" group. Additionally, the frequency of using painkillers according to WHO step-ladder, Pain Management Index (PMI), or patients own knowledge and attitude toward cancer pain control was not found to be relevant to patients satisfaction (P=0.106, P=0.382, P>0.05). But, in the "satisfaction" group, more patients were informed of the importance of pain management (P=0.004) and reported less pain (P<0.05). A close relationship between higher satisfaction and lower pain interference rate was discovered, but no correlation was found for activity, mood, or gate. The average of interference rate was lower in the "satisfaction" group (P<0.05). CONCLUSION: For higher satisfaction rate for pain management among cancer patients, high activity rate, patient education of importance of pain management, less severity of pain, and low interference rate in life are found to be the determinants.

BACKGROUND: Adenocarcinoma arising in the body or tail of the pancreas tends to be metastasized at the time of diagnosis, is mostly in inoperable stage, and poor in prognosis. In this study, we evaluated the adenocarcinoma arising in the body or tail of the pancreas and investigated the prognostic factors and ideal treatment. MATERIAL AND METHODS: We retrospectively analyzed 33 patients who were cytologically or histologically confirmed as adenocarcinoma in the body or tail of the pancreas at Samsung Medical Center from October 1994 to December 1999. RESULTS: The mean age of the patients in the resectable and unresectable groups were 63.4 and 60.6 year-old, respectively. The mean CA19-9 level was higher in unresectable group (5166.2u/ml), compared to the resectable group (964.7u/ml).(p=0.039) In the resectable group, the body was the most common location of the tumor, and in the unresectable patient group, the tail was more prevalent.(p= 0.021) The mean survival time of the resectable group was 15.1months. The univariate analysis of the resectale group showed that the age, sex, lymph node metastasis, chemotheraeutic modalities, radiotherapeutic modalities, and the location of tumor were not significantly related with the prognosis. In unresetable group, the mean survival time was 6.4months. The mean survival time were 3.3 months in patients over 60 year-old and 9.9 months in patients less than 60, showing statistically significant difference.( p=0.007) The mean survival time were 12.2 months and 3.4 months in patients who received the chemotherapy and who did not, respetively.(p=0.004) Evaluating the relationship between the extent of metastasis and survival, the mean survival length of single metastasis was 9.3 months, showing significantly higher survival length compared that of multiple metastasis.(p=0.027) Patient's sex, radiotherapeutic modality and location of the tumor were not significantly related with the prognosis. Multivariate analysis of prognostic factor showed that the patietnt's age (p=0,842), the extent of metastasis( p=0.458), and chemotherapeutic modality (p=0.078) were unrelated with prognosis. CONCLUSION: In adenocarcinoma arising in the body and tail of the pancreas, the CA19-9 level and tumor location could be utilized as indicating factors of the operability of the tumor. Age, sex, lymph node metastasis, and location of the adenocarcinoma are not significantly related with the survival length in both the resectable and unresectable groups. Also, in both groups, the chemotherapeutic and radiotherapeutic modalities were not related with the survival length.

The prognosis of oral malignant melanoma is poor compared with cutaneous melanoma. It may be related to the difficulty of wide enough resection, the early hematogenous matastases, higher stage at initial diagnosis, and tendency to growth vertically. In the view of histological differences between oral mucosa and skin, it is impossible use Clark's and Breslow's classifications for prognosis. The great problem is that there is still no consensus on the treatment due to rarity. Because data collection from case reports is considered to be the best source of information and should be pooled to analyze key determinants of outcome, We analysed 6 cases of primary malignant melanoma of the oral cavity which were diagnosed and treated in Pusan National University Hospital on recent 7 years and reviewed the literatures. Immunohistochemical study on S 100 Protein, GP 100 (HMB-45) with biopsy was usable to confirm the melanoma. Three patients who were treated by surgery, chemotherapy are alive, but a patients who couldn't received benefit care surgically due to poor condition was died of distant metastasis, and two patients who refused to surgery are still alive. Neck dissection including wide excision is recommended if lymph node involvement is suspected. Additionally, adjuvant chemotherapy could be considered as supporting therapy for malignant melanoma.
