PURPOSE: The aim of the study was to evaluate the clinical outcome and complications of tension free vaginal tape (TVT) procedure for the surgical treatment of female stress urinary incontinence. MATERIALS AND METHODS: Between April 1999 and May 2000, 41 women with stress urinary incontinence underwent TVT procedure. Preoperative evaluation included questionnaires study, physical examination, one hour pad test and urodynamic study. Postoperative clinical outcome, patient's satisfaction and complications were checked after 3-months. RESULTS: The mean age of patients was 51.6 years (range 40-76) and mean hospital stay 2.1 days (range 1-10). The mean follow-up period was 9.9 months (range 3-15). Thirty six patients (87.8%) were cured, 2 patients (4.9%) were improved. Two of 3 patients with failed operation who developed postoperative urge incontinence had grade III cystocele. Five bladder perforations and 1 obturator nerve injury occurred. The abdominal leak point pressure (LPP) increased from 50.6cmH20 to 110.8cmH2O, detrusor pressure of maximal flow rate (Pdet.Qmax) increased from 15.8cmH2O to 28.6cmH2O and maximal flow rate (Qmax) decreased from 32.8ml/s to 22.5ml/s after operation. CONCLUSIONS: The TVT procedure is an effective and feasible surgical treatment for female stress urinary incontinence. However, in patients with grade III cystocele, postoperative urge incontinence may develop after the procedure. Since TVT procedure involves securing the mid-urethra, urinary obstruction may also occur, necessitating the need for continued follow-up as well as a careful comparison with other sling procedure.

PURPOSE: The aim of this study was to develop a baptist electronic Nutritional Screening Program (B-eNSP) that could be easily used to identify patients with nutrition at risk or malnutrition on their admission to hospital using an integrated medical information system and to evaluate validity, reliability and efficiency of B-eNSP. METHODS: From June 1 2009 to June 21 2009, we enrolled 496 patients for prospective research. We analyzed age, sex, weight, height, weight loss in the last 3 months, serum albumin, alteration of dietary intake, gastrointestinal symptom, functional capacity, diagnosis and its relationship to nutritional requirements, physical examination and Subjective Global Assessment (SGA). B-eNSP included body mass index (BMI), weight loss in the last 3 months, serum albumin. Each component was scored. Sensitivity and specificity were calculated to evaluate the validity of the B-eNSP. The receiver operating characteristic (ROC) curve was drawn by using B-eNSP to choose a cut-off value that maximizes sensitivity and specificity and Yoden Index. Comparison with SGA and the reliability of the B-eNSP was done using kappa statistics. RESULTS: The maximum Yoden Index was 0.866 and the cut-off value of the ROC curve was 2. A B-eNSP score higher than 2 was defined as nutrition at risk or malnutrition. Reliability of the B-eNSP was in accordance with SGA by kappa 0.845. CONCLUSION: The B-eNSP can be used efficiently to identify patients with nutrition at risk or malnutrition by simply using an integrated medical information system.

Background and Objectives:
Recurrence rates after radiofrequency catheter ablation (RFCA) in atrial fibrillation (AF) patients are not low especially in non-paroxysmal AF. The diameter of left atrium (LA) has been widely used to predict the recurrence after RFCA for decades. However, LA diameter represents structural remodeling of LA and does not reflect electrical remodeling. We aimed to determine the predictive value of electrical remodeling of LA which is represented by the amount of low voltage zone (LVZ).
Methods:
We performed a retrospective cohort analysis of AF patients who underwent de novo RFCA in a single-center.
Results:
A total of 3,120 AF patients with de novo RFCA were analyzed. Among these patients, 537 patients underwent an electroanatomic mapping with bipolar voltage measurement of LA.The diameter of LA and flow velocity of LA appendage (LAA) differed significantly according to quartile group of LVZ area and percentage: patients with high LVZ had large LA diameter and low LAA flow velocity (p<0.001). Freedom from late recurrence (LR) was significantly lower in patients with high LVZ area and percentage (p<0.001). The diameter and surface area of LA had area under curve (AUC) of 0.592 and 0.593, respectively (p=0.002 for both). The predictive value of LVZ area (AUC, 0.676) and percentage (AUC, 0.671) were both superior compared with LA diameter (p=0.011 and 0.027 for each comparison).
Conclusions
In conclusion, LVZ can predict freedom from LR after RFCA in AF patients. Predictive value was higher in parameters reflecting electrical rather than structural remodeling of LA.

PURPOSE: The purpose of this study was to review systematically the effects of home based pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) patients using qualitative synthesis. METHODS: Studies designed randomized controlled trials were identified to extract data and to assess the quality of studies in 8 domestic and 3 foreign search engines, and hand search reference reviews. RESULTS: A total of 9 studies met the inclusion criteria. Overall, the methodological quality of the studies ranged from average to poor. Home based pulmonary rehabilitation consisted of exercise, education, and psychosocial interventions. Several exercises such as aerobic, strength, respiratory muscle training, and flexibility were used in home based pulmonary rehabilitation for COPD patients. Upper muscle exercise and walking were the most frequently used exercises. The most common topics for education were ‘knowledge of the illness’ and ‘drug management’. Walking distance test (WDT) and quality of life (QoL) were the most frequently measured as the dependent variables to evaluate rehabilitation outcomes, followed by pulmonary function test (PFT) and dyspnea. WDT was the most effective outcome, followed by dyspnea, QoL and PFT. CONCLUSION: This study informed about the details of scientific and effective home based rehabilitation programs in COPD patients for future researchers and clinicians. These findings can help expand the recognition and accessibility of home based rehabilitation in COPD patients.

PURPOSE: Heart to liver ratio on T1-201 per rectal scintigraphy (shunt index) is known to be useful in the assessment of portal systemic shunt. We assessed T1-201 uptake pattern and early liver/heart uptake rate of T1-201 and correlated with shunt index in patients with chronic active hepatitis (CAH) and liver cirrhosis (LC). MATERIALS AND METHODS: Fifty eight patients with biopsy-proven chronic liver disease (35 with CAH, 23 with LC) underwent T1-201 per rectum scintigraphy after instillation of 18.5 MBq of T1-201 into the upper rectum. We evaluated hepatic uptake (type 1: homogeneous, 2: inhomogeneous segmental, 3: inhomogeneous nonsegmental) and extrahepatic uptake of spleen, heart and kidney (grade 0: no uptake, 1: less than liver, 2: equal to liver, 3: greater than liver). We measured the early liver/heart uptake rate (the slope of the liver to heart uptake ratio for 10 min) and shunt index (heart to liver uptake ratio). T1-201 uptake pattern and early liver/heart uptake rate of T1-201 was correlated with the pathologic diagnosis and shunt index. RESULTS: Hepatic uptake patterns of type 1 and 2 were dominant in CAH (CAH: 27/35, LC: 8/23), and type 3 in LC (CAH: 8/35, LC: 15/23) (p<0.005). The grades of extrahepatic uptake were higher in LC than in CAH (spleen: p<0.001, other soft tissue: p<0.005). The early liver/heart uptake rate of CAH (0.110+/-0.111) was significantly higher than that of LC (0.014+/-0.090) (p<0.001). The sensitivity and specificity of the early liver/heart uptake rate were 77.7% and 67.7% in differentiating LC from CAH. There was negative correlation between early liver/heart uptake rate and shunt index (r=-0.3347, p<0.01). CONCLUSION: Hepatic and extrahepatic uptake pattern and early liver/heart uptake rate on T1-201 per rectum scintigraphy are useful in the assessment of portal systemic shunt in patients with chronic liver disease.

Nine patients of clinically definite multiple sclerosis (MS) were examined by magnetic resonance imaging (MRI) at 1.0T. The MS plaques were seen in the brain and spinal cord in eight and three patients. respectively. The frequent sites of MS plaques were periventricular white matter, brain stem, and cervical cord. The shape of most brain MS plaques was round or finger-like configuration. The MS plaques showed high signal intensity on R2 weighted images and low or iso signal intensity on T1 weighted images in all nine cases. Contrast enhancement was seen in 4 cases. Mild brain atrophy was noted in 2 cases and mass effect in 1 case. The sites of cord MS plaques in three patients were C2-C4, C2-C5, and C4-C6 levels respectively. The cord MS plaques showed high signal intensity on T2 weighted image and contrast enhancement on Gd-DTPA enhanced T1 weighted images in all 3cases with mild cord expansion in 2 cases. In conclusion, MRI is a useful diagnostic tool in evaluationg the MS plaques involving central nervous system.

The relationship between the intestinal histopathology and number and position of intraepithelial lymphocytes (IEL) was observed chronologically in the small intestine of rats experimentally infected with Metagonimus yokogawai. Fifteen Sprague-Dawley rats were orally infected each with 3,000 metacecariae, and 3 were kept uninfected for controls. Three rats each were sacrificed on the day 5, 10, 15, 24 and 70 post-infection (PI) and samples of the small intestine, 5 cm, 10 cm, 20 cm and 70 cm posterior to the pylorus were taken. The samples were processed routinely and stained with Giemsa. The intestinal histopathology was severe during the day 5-15 PI and characterized by villous atrophy, crypt hyperplasia, and decrease of villus/crypt height ratio. After the day 24 PI, the intestinal lesions showed some tendency of recovery. The number of IEL increased at the early stage of infection, but decreased thereafter to a lower level than that of controls, with progression of the pathological changes. Then, the IEL number began to increase again after the day 24 PI. In control rats, the great majority of the IEL were located at the basal region of the epithelium. During the early stage of infection, however, a considerable proportion of IEL was found to have moved to the intermediate or apical region of the epithelium. From the above results, it is suggested that the change of IEL number and position during the course of M. yokogawai infection should be closely related to the progression and recovery of the intestinal histopathology.

STUDY OBJECT: To date, the study of critical illness in the emergency department has been limited. The purpose of this study was to determine the length of stay and procedures performed on critical care patient in ED, and to be help to establish Emergency physicians' education program. METHOD: We reviewed patient's medical record, who visited ED, Korea Univ. Hospital from Jan. 1996 to Jun. 1996 and admitted to ICU. We analyzed data to age, sex, clinical diagnosis, length of stay, and critical procedures in ED. RESULTS: The 12,721 patients visited ED during the study period, the 441 of 12,721 (3.50%) patients admitted to ICU. 56 patients were excluded whose medical re cords were incomplete. The study populations consisted of 165 women and 220 men. The mean age were 52 year old (median,58 year old). The mean length of stays were 606.1 (1445.9 minutes (median, 180 minutes)). One hundred sixty one of these patients (41.8 %) received one or more critical procedures. The medical critical patients were 252 cases, and surgical critical patients were 133 cases. The mean length of stay of medical critical patients was 738.8 (1748.9 minutes (median, 177.5 minutes)) in medical department,44.0% of them received critical procedures in ED. The surgical critical patients averaged 354.9 (410.7 minutes (median, 190 minutes)) and 37.6% received critical procedures. CONCLUSION: Critical ill patients stay in the ED with a substantial amount of time, before addition to the ICU. Critical ill patients who have hemodynamiccal unstable conditions, compromised cardiopulmonary functions, and neurologic deficities, were managed in ED frequently. Typical critical care procedures are commonly performed by emergency physicians. Therefore, it is important for emergency physician to prepare to critical ill patients.

9.Surgical Reconstruction of Nasal Alar Deformities.
Journal of Rhinology 2017;24(2):65-73
Reconstruction of the nasal alar may be challenging due to the complex nature of multiple cosmetic units and functional considerations, including maintenance of valvular competency. Reconstructive options include various flaps or graft repairs, depending on the subunit involvement and the size of the defect. Linear closures may be suitable for small defects, while bilobed flaps, melolabial flaps, and forehead flaps may be considered for moderate to large defects involving partial and full-thickness defects of the ala.

PURPOSE: The prognosis of non-Hodgkins lymphoma (NHL) in elderly patients seems to be poorer than that in patients aged less than 60 years. This may be due to the lower tolerance for combination chemotherapy in the elderly. Aggressive combination chemo-therapy, which is the treatment of choice in intermediate and high grade NHL of adulthood, may be associated with unpredictab1y severe and lethal toxicity and worsened quality of life in the elderly. We investigated the treatment responses, toxicities and prognostic factors of NHL in elderly patients treated with combination chemotherapy. MATERIALS AND METHODS: We treated 116 elderly (>60 yrs) patients with NHL between January 1986 and June 1996 with adriamycin-containing regimens, such as CHOP (cyclo- phosphamide, adriamycin, vincristine, prednisolone), BACOP (bleomycin, adriamycin, cyclophosphamide, vincristine, prednisolone), and mBACOP (methotrexate, bleomycin, adriamycin, cyclophosphamide, vincristine, prednisolone). Patients in this study ranged from 60 to 81 (median 67) years of age. Fifty-five percent of patients were in stage I or II and the rest (45%) were in stage III or IV. The histologic grade was predominantly (91%) of intermediate and high grade type. RESULTS: The treatment responses were complete (CR) in 55% and partial (PR) in 25%. The median durstion of CR was 32 (3-132) months. The CR rate was significantly higher in patients treated with RDI (relative dose intensity) > 75% than that in the patients treated with RDI < 75% (p 0.003), but there was no significant difference in CR rate between treatment regimens (p-0.38). At a median follow up of 48-months (range, 12 to 132 months), the estimated 5-year ovetall survival was 46%. Ann Arbor Stage (I, II vs III, IV), ECOG performance (0-1 vs 2-3), RDI (>75% vs <75%) and the treatment response were important prognostic factors in the univariate analysis, and the treament response (CR vs non-CR) was the only independent prognostic parameter in the multivariate analysis. The most frequent and severe toxicity associated with chemotherapy was infection with or without neutropenia. The rate of severe infection was significantly decreased in the patients supported with G/GM-CSF but not in the dose-reduction group (RDI<75% vs >75%). CONCLUSION: Our data suggests that achievement of the CR after combination chemotherpy is the most important prognostic factor in the elderly patients with NHL. Suboptimal chemotherapy (RDI<75%) reduced the complete remission rate without reducing the likelihood of developing severe toxicities. Optimal chemotherapy with supportive cares involving the use of hematopoietic growth factors may be needed to improve the treatment response and the survival in the elderly patients with aggressive NHL.
