PURPOSE: In 1970, the Berlin-Frankfurt-Munster(BFM) group introduced an intensification therapy after remission induction to reduce relapse of acute lymphoblastic leukemia(ALL) in childhood. Delayed intensification(DI) phase has been included for treatment of ALL in our hospital since the mid-1990s. The purpose of this study is to evaluate the outcome with vs. without DI phase and the outcome with two vs. one DI phase for intermediate risk patients. METHODS: One hundred and thirty nine children with ALL who were treated at the Department of Pediatrics of Wonju Christian Hospital and Yonsei University Medical Center between March, 1990 and July, 2002 were analysed retrospectively. RESULTS: Thirty-eight patients were treated with a DI phase, and 101 patients were treated without a DI phase. Among the DI patients, seven patients were treated with a double DI phase. Five-year overall survival(OS) in the low, intermediate, and high risk groups were 68%, 66% and 58%, respectively. 5-year OS in DDI, DI, and control were 95%, 86% and 40%, espectively. In the low risk group, 5-year event free survival(EFS) in DI, and control were 94% and 58%, respectively. CONCLUSIONS: Delayed intensification improved EFS on childhood ALL in all risk groups.

BACKGROUND/AIMS: Ulcerative colitis (UC) is a chronic inflammatory bowel disease with heterogeneous clinical features. Data on the disease course and prognosis of UC patients who have been regularly treated are lacking. We aimed to investigate relapse rates of UC in remission and factors related to relapse. METHODS: We retrospectively analyzed clinical courses of 84 patients (43 males, median age 43 years, ranged 20-73 years) diagnosed as UC at Ajou University Hospital between January 1997 and December 2005 based on clinical, endoscopic and pathologic findings, and who were regularly followed for at least one year after the remission. RESULTS: Study subjects consisted of 32 proctitis (38%), 21 left-sided colitis (25%), and 31 subtotal or total colitis (37%). Of 84 patients, relapse was observed in 52 patients (62%) during the follow-up period (ranged 1-9 years). The relapse rate was 24%, 41%, 51%, 65%, 71%, and 79% at 1 year, 2 years, 3 years, 4 years, 5 years and 6 years, respectively. Among sex, age, hemoglobin, ESR, and the extent of disease on admission, decrease of hemoglobin level was the only independent factor related to relapse (odds ratio=2.67, 95% CI (1.32-5.42), p<0.01). CONCLUSIONS: In Korea, relapse of UC in remission is not rare. Decrease of hemoglobin level is an independent risk factor related to its relapse, while the extent of disease is not.

In acute stroke, emboli are mostly composed of thrombi from artery, cardiac chamber, valve and vein. Non-thrombotic emboli are sometimes difficult to identify the origin. According to the increased number of cancer patients, now 10% of stroke patients have a cancer. However, the potential mechanisms of stroke in patients with cancer are various. We presented a case of serious acute arterial occlusion with a tumor embolus, which was revealed by histopathologic analysis of retrieved emboli during mechanical thrombectomy.

Pneumoperitoneum, Pneumomediastinum, subcutaneous emphysema and a pneumothorax are some of the mechanical complications of bronchial asthma. The incidence of pneumoperitoneum during an attack of acute asthma is rare. The pathogenesis is free gas track from the overdistended alveoli, through the bronchovascular sheaths to the mediastinum. If the high pressure is maintained, air can escape retroperitoneally into the abdomen and burst into the peritoneal cavity. A 43-year-old woman was admitted due to a severe asthma attack. She was required endotracheal intubation and AMBU(air mask bag unit) ventilation. Immediately after these procedures, pneumoperiotneum, pneumomediastinum, and subcutaneous emphysema daveloped. She was treated with mechanical ventilation and medical therapy. The pneumoperitoneum was resolved after 27 days. Here, we report this case with the review of the relevant literature.

BACKGROUND AND OBJECTIVES: Left atrial (LA) fibrosis is a main determinant of LA remodeling and development of atrial fibrillation. However, non-invasive prediction of LA fibrosis is challenging. We investigated whether preoperative LA strain as measured by speckle tracking echocardiography could predict the degree of LA fibrosis and LA reverse remodeling after mitral valve (MV) surgery. SUBJECTS AND METHODS: Speckle tracking echocardiography and LA volume measurements were performed in 50 patients one day before MV surgery. LA tissues were obtained during the surgery, and the degrees of their interstitial fibroses were measured. LA volume measurements were repeated within 30 days after surgery (n=50) and 1-year later (n=39). RESULTS: Left atrial global strain was significantly correlated with the degree of LA fibrosis (r=-0.55, p<0.001), and its correlation was independent of age, underlying rhythm, presence of rheumatic heart disease and type of predominant MV disease (B=-1.37, 95% confidence interval -2.32 - -0.41, p=0.006). The degree of LA fibrosis was significantly correlated with early (r=-0.337, p=0.017) and 1-year (r=-0.477, p=0.002) percent LA volume reduction after MV surgery, but LA global strain was not significant. CONCLUSION: Left atrial strain as measured by speckle tracking echocardiography might be helpful for predicting the degree of LA fibrosis in patients with MV disease.

Cognitive impairment and depression are the most common symptoms affecting the elderly on physical and mental states. Studies have shown that these symptoms in mild cases are improved by psychosocial intervention, emphasizing the importance of therapeutic intervention provided in the community. The purpose of this study was to investigate whether the psychosocial program at a geriatric day care service has any therapeutic effect on the cognitive function and depressive symptoms in the elderly and whether such effect can be maintained. The experimental group was composed of 37 elderly patients attending the day care service at the mental health center located in Kwangju county, Kyonggi province. The control group was composed of 22 elderly patients who either refused intervention or who dropped out of the program. Cognitive function was assessed with the Korean version of the Mini-Mental State Exam(MMSE-K) and depressive symptoms were assessed with the Short-form Geriatric Depression Scale(SGDS) The experimental group and the control group were compared on the score of on each test, which was administered before and after the program and 10 weeks after discontinuation of program. In the experimental group, the scores acquired immediately after the program and at 10 weeks of follow-up were also compared. The results showed that psychosocial intervention at a geriatric day care service was significantly associated with the change in SGDS scores dependent on time but not significantly associated with the change in MMSE-K scores. In the experimental group whose follow-up assessment was possible, it was further shown that 43% of patients had increased SGDS scores 10 weeks after the program ended, indicating that depressive symptoms had worsened. This study suggests that psychosocial therapeutic intervention in the geriatric day care service improve depressive symptoms but not cognitive functions in the elderly. In addition, for a considerable percentage of subjects in the experimental group, the improvements in depressive symptoms were not sustained after the intervention was withdrawn. These findings proposes a need of strengthening therapeutic intervention to maintain such effect.

Recently, the number of facial contouring surgery such as angle reduction or malarplasty in Oral and maxillofacial surgery is increasing steadly as the demand for maxillofacial esthetic surgery of the patients is growing. Looking around international trend of oral and maxillofacial surgery, nowadays workshop or symposium about facial soft esthetic surgery such as corrective rhinoplasty, blepharoplasty, face lift are held. This means that maxillofacial esthetic surgery is new scope which oral and maxillofacial surgeons should develope. Therefore the authors present cases of blepharoplasty which got hardly used to oral and maxillofaical surgeon with literature review in order to raise the concern about maxillofacial esthetic surgery.

BACKGROUND/AIMS: Sometimes, the endoscopic stent insertion may be done without fluoroscopic guidance. This study was performed to evaluate the difference in success rate of endoscopic stent insertion with or without fluroscopic guidance. A total of hundred and sixty three patients with upper gastrointestinal obstruction were included. METHODS: The group I comprised 82 patients in which the stent insertion was done without fluoroscopy. The group II included 81 patients in which stent was inserted under the fluoroscopy. RESULTS: The locations of obstruction are at esophagus and cardia (group I /group II, 44/40 patients), at pylorus and duodenum (15/34 patients) and at post-operative stenosis of gastro-jejunal anastomosis (23/7 patients). The statistical difference of success rate were not found between the two groups [79/82 (96.3%) in group I, 80/81 (98.2%) in group II, p=0.620]. Among group I, three patients (3.7%) were failed due to incomplete guidewire insertion. These patients were the two cases of jejunal stenosis of esophago-jejunal anastomosis and one case of duodenal obstruction with carcinomatosis peritonei. However, in these cases, the stents were successfully inserted under the fluoroscopic guidance. CONCLUSION: The success rate of the endoscopic stent insertion with or without the fluoroscopic guidance is not different. But in cases of inaccurate guidewire insertion, especially in patients with pyloric obstruction, the endoscopic stent insertion under the fluoroscopic guidance may be more safe and successful.
