  • Since Jan. 1991 a prospective randomized study for Stage III unresectable non small cell lung cancer (NSCLC) has been conducted to evaluate the response rate and tolerance of induction chemotherapy with MVP followed by hyperfractionated radiotherapy and evaluate the efficacy of maintenance chemotherapy in Asan Medical Center. All patients in this study were treated with hyperfractionated radiotherapy (120 cGy/fx BID, 6480 cGy/54 fx) following 3 cycles of induction chemotherapy, MVP (Mitomycin C 6 $mg/m^2,$ Vinblastin 6 $mg/m^2,$ Cisplatin 60 $mg/m^2$) and then the partial and complete responders from induction chemotherapy were randomized to 3 cycles of adjuvant MVP chemotherapy group and observation group. 48 patients were registered to this study until December 1992; among 48 patients 3 refused further treatment after induction chemotherapy and 6 received incomplete radiation therapy because of patient's refusal, 39 completed planned therapy. Twenty-three $(58\%)$ patients including 2 complete responders showed response from induction chemotherapy. Among the 21 patients who achieved a partial response after induction chemotherapy,1 patient rendered complete clearance of disease and 10 patients showed further regression of tumor following hyperfractionated radiotherapy. Remaining 10 patients showed stable disease or progression after radiotherapy. Of the sixteen patients judged to have stable disease or progression after induction chemotherapy, seven showed more than partial remission after radiotherapy but nine showed no response in spite of radiotherapy. Of the 39 patients who completed induction chemotherapy and radiotherapy, 25 patients $(64\%)$ including 3 complete responders showed more than partial remission. Nineteen patients were randomized after radio-therapy. Nine Patients were allocated to adjuvant chemotherapy group and 4/9 showed further regression of tumor after adjuvant chemotherapy. For the time being, there is no suggestion of a difference between the adjuvant chemotherapy group and observation group in distant metastasis rate and survival. Median survival time was 13 months. Actuarial survival rates at 6,12 and 18 months of 39 patients who completed this study were $84.6\%,\;53.7\%\;and\;40.3\%,$ respectively. The partial and complete responders from induction chemotherapy showed significantly better survival than non-responders (p=0.028). Incidence of radiation pneumonitis in this study group was less than that in historical control group inspite of induction chemotherapy. All patients tolerated hypertractionated radiotherapy without definite increase of acute complications compared with conventional radiotherapy group. The longer follow up is needed to evaluate the efficacies of induction and maintenance chemotherapy and survival advantage by hyperfractionated radiotherapy but authors are encouraged with an excellent tolerance, higher response rate and improvement of one year survival rate in patients of this study.

  • We implanted pacemakers using screw-in sutureless myocardial electrode in 40 patients between February, 1980 and November, 1982 at Seoul Nation University Hospital. Mean age of total patient who received the pacemaker implantation was 39.9 years, but excluding the patient who received the open heart surgery, mean age was 49.3 years. Cause of pacemaker implantation was complete A-V block in 13 patients, symptomatic sick sinus syndrome in 12 patients, complete A-V block after open heart surgery in 12 patients, second degree A-V block with dizziness in one patient, and atrial fibrillation with slow ventricular response in two patients. In thirty nine cases, electrodes were implanted by subxiphoid approach, on the diaphragmatic surface of right ventricle. I n one case, electrode was implanted through the left anterior thoracotomy. Acute stimulation threshold, measured in 35 patients, varied from 0.1 to 2.5 mA [mean 0.85 mA.], and R-wave amplitude [sensitivity], measured in 19 patients, varied from 2.9 mV to 11.5 mV [mean 7.6 mV]. There was no hospital death. The postoperative complications included wound seroma in two patients [5%], wound hematoma in three patients [7.5%], and pacing failure in one patient [2.5%]. The subxiphoid implantation of the pacemaker using sutureless myocardial lead was valuable in obtaining safe, reliable and long-term impulse generation.

  • The On-Line Analytical Processing (OLAP) tools access data from the data warehouse for complex data analysis, such as multidimensional data analysis, and decision support activities. Current research has lead to new developments in all aspects of data warehousing, however, there are still a number of problems that need to be solved for making data warehousing effective. View maintenance, one of them, is to maintain view in response to updates in source data. Keeping the view consistent with updates to the base relations, however, can be expensive, since it may involve querying external sources where the base relations reside. In order to reduce maintenance costs, it is possible to maintain the views using information that is strictly local to the data warehouse. This process is usually referred to as "self-maintenance of views". A number of algorithm have been proposed for self maintenance of views where they keep some additional information in data warehouse in the form of auxiliary views. But those algorithms did not consider a consistency of materialized views using view self-maintenance. The purpose of this paper is to research consistency problem when self-maintenance of views is implemented. The proposed "conveyor algorithm" will resolved a complete consistency of materialized view using self-maintenance with considering network delay. The rationale for conveyor algorithm and performance characteristics are described in detail.

  • Ovarian cancer patients need a surveillance program for the detection of tumor progression after completion of treatment. The methods generally consist of history taking, physical examination, tumor marker monitoring and imaging. However, the details of recurrence detection with each method are not well defined. To clarify this issue, ovarian cancer patients who achieved complete or partial responses and developed tumor progression at the follow up time between January 2004 and December 2010 in University Hospital Chiang Mai, Thailand, were reviewed. Clinical data, CA 125 level and imaging results at the tumor progression time were recorded and analyzed. There were 144 ovarian cancer patients meeting the inclusion criteria with the mean age of 51 years and 62.5% of them were in an advanced stage. Complete response was achieved in 89 patients (61.8%) after primary treatment. The median progression free survival and overall survival were 15.5 months and 37.5 months, respectively. Abnormal symptoms presented in 49.3% of the studied patients and 59.7% developed physical examination abnormalities. In addition, CA 125 was elevated in 89.6% while in 74.3% of tumor progression was identified by CT-scan. Short treatment time period and a high level of CA 125 were significant independent prognostic factors in these patients. In conclusion, careful history taking, physical examination and monitoring of CA 125 levels are important methods for tumor progression detection in a surveillance program for epithelial ovarian cancer patients.

  • Paraneoplastic nephrotic syndrome can be diagnosed from its clinical and immunological features. The development of several types of glomerular injury in patients with cancer have been recognized, and are considered as paraneoplastic syndrome. Most prominent are the occurrence of membranous glomerulonephritis in patients with carcinomas. We report a case of a 60-year-old-man with small cell lung cancer presenting as nephrotic syndrome. A renal biopsy revealed membranous glomerulonephritis. Six lots of chemotherapy were administered, which led to a complete tumor response with total resolution of the nephrotic syndrome following treatment.

  • Calcinosis cutis is a chronic condition characterized by insoluble calcified deposits in the skin and subcutaneous tissue. Although there is no uniformly effective treatment for calcinosis cutis, minocycline therapy has demonstrated varying degrees of benefit in humans. Five client-owned dogs with calcinosis cutis were included. Minocycline was administered orally in a dose of 10 mg/kg bodyweight twice a day. Treatment was repeated every day until complete remission. The efficacy of minocycline was evaluated within this period. The side effects of minocycline were monitored and reported by the owners and veterinarians. Of the 5 dogs with calcinosis cutis, which was classified as the dystrophic form, four dogs had a complete remission of calcinosis cutis and one dog had a partial response. The major improvement was a reduction in the size of the calcified deposits and reduction in inflammation associated with them. The duration of remission was $9.1{\pm}2.2$ weeks. The adverse effects, observed in one dog, were anorexia and vomiting. Minocycline may be effective in the control of calcinosis cutis in dogs.

  • Hepatocellular carcinoma (HCC) is the sixth most common cause of death worldwide and the main cause of primary liver cancer. The principle problem of HCC is the poor prognosis, since advanced HCC reportedly has a median survival of only 9 months. The standard therapies are sorafenib and regorafenib, but the outcomes remain unclear. We report a 60-year-old man with advanced HCC with right adrenal gland metastasis and portal vein tumor thrombosis, who showed a complete response to multiple applications of an interdisciplinary therapy.

  • Accelerator driven subcritical systems have long been discussed as facilities which can be used for solving the nuclear waste problem. The physics of these systems is very different from conventional reactors and new techniques had to be developed for reactivity monitoring. One such technique is the Area Ratio Method which studies the response of a subcritical system upon insertion of a large number of neutron pulses. An issue associated with this technique is the spatial dependence of measured reactivity which is intrinsic to the sub criticality of the system since the reactor does not operate on the fundamental mode and measured reactivity depends on the detector position. This is generally addressed by defining Bell-Glasstone spatial correction factor. This factor upon multiplication with measured reactivity gives the correct reactivity which is independent of detector location. Monte Carlo Methods are used for evaluating these factors. This paper presents a complete three dimensional map of spatial correction factors for BRAHMMA subcritical system. In addition, the dataset obtained also helps in identifying detector locations where the correction factor is close to unity, thereby implying no correction if the detector is used at those locations.

  • The aim of this study was to investigate the early outcome of the taxotere and cisplatin chemoradiotherapy for advanced cervical cancer. Fifty-six cases (FIGO II b to IVa) were divided randomly into two groups: radiotherapy alone (28 cases) and radiation plus chemotherapy (TP) group. There was no difference in radiotherapy between the two groups. The RT+C cases who received TP regimen during the radiation, and DDP once weekly injection of vain, according to 20$mg/m^2$ and taxotere once weekly iv according to 35 $mg/m^2$. These regimens were given for 4~5weeks, and some medicines to control vomiting were available for the RT+C cases. The two groups received an oral medicine MA 160mg every day during the treatment. Regarding early outcome, the complete remission rate was 64.3% and partial remission rate was 35.7% in RT+C. The complete remission rate was 32.1% and partial remission rate was 39.3% in RT. The total response rate and complete remission in the RT+C group were higher than that in the RT group. We conclude that taxotere and cisplatin chemoradiotherapy can improve the early outcome of the advanced cervical cancer, the adverse effects being endurable.
