OBJECT: This study is focused on the comparison between CO2 laser and scalpel by examining the overal process of wound healing after partial glossectomy of rats so that the result from the research could be easily applied to actual clinical environment. METHOD AND MATERIAL: In this research, 2mm defect was formed on both lateral borders of the tongue of rats by using CO2 laser and scalpel respectively. 4rats were sacrified each time on the 1st, 2nd, 4th, 7th, 14th and 21th day according to a general method. After fabricating 5 micrometer paraffin specimen, H&E staining and MT staining were performed. RESULTS: Compared to scalpel, wound healing by CO2 laser leads to a earlier initiation of vascular proliferation and re-epithelization. Therefore, some influence is exerted on the early stage of wound healing. However, the two methods seem to undergo the similar healing process.

BACKGROUND: Abdominal pain is one of the most common complaints in the emergency department and the evaluation presents an extraordinary challenge to the emergency physician's skill. C-reactive protein, an acute phase protein which is increased in the presence of inflammation in various clinical conditions, has been proven useful in assessing disease severity, in monitoring the development of complications, and in evaluating the response to specific treatments. So we tried to determine whether CRP offers an advantage over other clinical or laboratory variables for decision-making in the management of acute abdominal pain in the emergency department. METHOD: Patients who came to a University Hospital ED with acute abdominal pain, between september 1, 1998 and November 30, 1998, were included in this study, Data collection included age, sex, duration of symptom, location of pain, and laboratory dta(white blood cell count, portion of neutrophils, ESR, CRP, amylase). RESULT: This study included 85 patients, 34 of whom were men. The mean age was 36.9+/-19.1 years. CRP might be useful to detect the serious condition, sensitivity 81%, but more useful to differentiate normal condition from serious condition in acute abdominal pain patients, specificity 83%. CONCLUSION: CRP is an useful indicator of decision-making to abdominal patients in the emergency department. Hospitalization or operation is very unlikely when CRP value is normal.

The case of postoperative hemorrhage occurring apart from the operative site as a complication of intracranial surgery is a rare malady, especially when it involves the cerebellum after supratentorial aneurysm surgery. In a review of the literature, the possible etiologies for cerebellar hemorrhage are: coagulopathy, intraoperative urokinase irrigation, excessive head rotation on positioning, brain shift due to excessive cerebrospinal fluid(CSF) and epidural hemovac drainage. We experienced six cases of cerebellar hemorrhage after supratentorial aneurysm surgery, and all of the patients were improved by instituting conservative medical treatment. The possible mechanism for the remote cerebellar hemorrhages seen in our series is probably a multifactorial effect, such as excessive epidural hemovac and CSF drainage, and jugular venous compression due to the operative position. The purpose of this report is to alert neurosurgeons to the existence of this syndrome and to suggest several ways of minimizing the possibility of their patients developing remote cerebellar hemorrhage.

Purpose:
Approximately 30%-40% of pediatric acute myeloid leukemia (AML) patients relapse. In this study, we analyzed the outcome and prognostic factors of relapsed AML patients who had previously received first-line therapy at our institution.
Materials and Methods:
The study group consisted of 50 patients who had been diagnosed with AML from April 2009 to December 2018, and then showed first relapse. Thirty-two of the patients (64%) had previously received allogeneic hematopoietic stem cell transplantation (HSCT) in first complete remission (CR).
Results:
Forty-five of the patients (90%) received intensive chemotherapy upon diagnosis of relapse, and 76% (34/45) of these patients achieved a second CR. Estimated 5-year overall survival for these 45 patients was 44.9%±7.6%. Time from diagnosis to relapse, extramedullary involvement (EMI) at diagnosis, core binding factor AML, and complex karyotype were significant prognostic factors; in multivariate study, both time from diagnosis to relapse and EMI at diagnosis proved significant. There was no difference in 5-year disease-free survival between patients previously treated with chemotherapy only and those who received HSCT in first CR (52.4%±14.9% vs. 52.6%±11.5%). Of the 19 patients who achieved second CR after previous allogeneic HSCT in first CR and subsequent relapse, 11 were treated with chemotherapy only, and seven survive disease-free.
Conclusion
Intensive therapy allowed for long-term survival in 40%-50% of patients, and 50% of patients who achieved second CR, regardless of prior treatment modalities in first CR. Intensive treatment may allow for salvage of a significant portion of patients with relapsed pediatric AML.

Emphysematous cystitis is a rare disease that is associated with diabetes mellitus, neurogenic bladder, chronic genitourinary infection, and malignancy. Fever, chill, abdominal pain, and urinary difficulties were the most frequent presenting symptoms associated with emphysematous cystitis. We report a case of incidentally detected asymptomatic emphysematous cystitis in a 67 years old female patient with diabetic nephropathy. We review characteristic features of all 19 cases that has been reported in korean medical journals till now. Risk factors for this condition appear to be female sex, old age, and diabetes mellitus.

BACKGROUND: When patients return to the emergency department shortly after being seen, it is generally assumed that their initial evaluation or treatment was inadequate. But in other aspects many short term revisits may be unnecessary in the aspect of emergency care because it is known that substantial numbers of patients use emergency department for nonemergency problems. So we analysed the tendency and the cause of short term revisit patients, determined the rates and the associated demographic, clinical, disease variables as a tool of quality assurance. METHODS: We carried out a chart review of patients seen in the emergency department, who revisited within 72 hours, of Young Dong Severance Hospital retrospectively between January 1, 1998 and September 30, 1999 (period 2), and compared with result between April 1, 1990 and March 31, 1991 (period 1) respectively. RESULTS: In the period 1, the total revisits patients were 204/21,025(0.97%), in that period scheduled revisits were 15.2%, the unscheduled were 84.8%, and the frequent revisits (more than 3 times) were 6.4%. In the period 2, the total revisit patients were 4,722/72,802 (6.49%), in that period scheduled revisits were 86.3%, the unscheduled were 13.7%, and the frequent revisits were 24.8%. The most common cause of revisit during the period 2 is a drug addictor (31.2%) that frequently used the emergency room for seeking drug. CONCLUSIONS : The scheduled revisit patients for dressing, medication, re-evaluation were increased enormously, so the medical care of these patients might be a part of job that performed in emergency department. And if the health care system could support the adequate nursing care facility, the portion of avoidable revisits of emergency department can be decreased. We also found that the emergency department is an important points for the early identification and referral for the treatment of patients who revisited emergency room for seeking drug, and the analysis of physician related factor in revisits patients may be used as a tool of quality assurance in the emergency department.

Infundibular dilatation is funnel-shaped symmetrical enlargement that occurs at the origin of cerebral arteries and which is apparent on 7 to 25% of normal angiograms 3,4,7,10,12,13,15). Infundibular dilatation is frequently considered a normal anatomic variation of no pathologic significance. The authors report a case in which an aneurysm developed on an infundibular dilatation of the posterior communicating artery (PComA). A 72-year-old woman presented with severe headache, nausea, and vomiting. Digital subtraction angiography showed a saccular aneurysm arising from the origin of the left PComA. Operative findings revealed the aneurysm and infundibular widening of the right PComA. The aneurysm was successfully obliterated. Whether infundibular dilatation is a pre-aneurysmal state or a benign dilatation is controversial. However, we believe infundibular dilatation of the PComA in this case may have served as a pre-aneurysmal lesion.

The University of California, San Francisco, announced in 2011 Cancer of the Prostate Risk Assessment Postsurgical (CAPRA-S) score which included pathologic data, but there were no results for comparing preoperative predictors with the CAPRA-S score. We evaluated the validation of the CAPRA-S score in our institution and compare the result with the preoperative progression predictor, CAPRA score. Data of 130 patients were reviewed who underwent radical prostatectomy for localized prostate cancer from 2008 to 2013. Performance of CAPRA-S score in predicting progression free probabilities was assessed through Kaplan Meier analysis and Cox proportional hazards regression test. Additionally, prediction probability was compared with preoperative CAPRA score by logistic regression analysis. Comparing CAPRA score, the CAPRA-S score showed improved prediction ability for 5 yr progression free survival (concordance index 0.80, P = 0.04). After risk group stratification, 3 group model of CAPRA-S was superior than 3 group model of CAPRA for 3-yr progression free survival and 5-yr progression free survival (concordance index 0.74 vs. 0.70, 0.77 vs. 0.71, P < 0.001). Finally the CAPRA-S score was the more ideal predictor concerned with adjuvant therapy than the CAPRA score through decision curve analysis. The CPARA-S score is a useful predictor for disease progression after radical prostatectomy.
