AbstractAbstract PDF
Functional electrical stimulation (FES) has developed over the last 35 years to become a scientifically, technologically and clinically recognized field of interest in clinical medicine. FES has been applied to locomotion, grasping, ventilation, incontinence, and decubitus healing. However, all of these achievements illustrate the initial applications of FES; its true potential has not yet been realized. Recently, FES systems, which are miniaturized stimulation devices, have been utilized in the clinical setting. However, because the stimulating electrodes of the current FES devices are percutaneous electrodes, which are susceptible to wire breakage, and skin infection an implantable FES stimulating electrode has been introduced in the U.S. and Japan. In the present study, an external power supply method using radio frequency (RF) coupling and data transmission was developed for the control of the implantable FES device. In addition, we review the current understanding of FES devices and their application in clinical medicine.

BACKGROUND
It is well known that non-rapid eye movement(NREM) sleep activates the occurrence of interictal epileptiform discharges(IED) in many epileptic syndromes. We performed this study to assess the effect of NREM sleep on IED in epileptic patients with organic brain lesions. MATERIALS AND METHODS: We analyzed awake and sleep electroencephalopathy(EEG) recorded simultaneously after partial sleep deprivation in 50 patients. We calculated the awake and sleep spike index (ASI and SSI, spikes/epoch), and the percentage increase of ASI and SSI during sleep. RESULTS: In the 50 patients, the IEDs were recorded exclusively during the awake state in 1 (2%) patient, and during the sleep state in 13(26%) patients. The SSI was higher in 44 (88%) patients, and the ASI was higher in 5 (10%) patients. The mean ASI and the SSI in patients with organic brain lesions were 0.058+/-0.121 and 0.148+/-0.187, and it was 0.081+/-0.150 and 0.174 +/-0.226 in patients without organic brain lesions. There were significant increases in the spike index (P<0.05) during NREM sleep in both groups (n=36), but no significant difference in the percent increase of spike index (P>0.05). CONCLUSION: The IEDs were activated significantly during NREM sleep both in patients with and without organic brain lesions, but there were no differences in the degree of activation in both groups. The activating effect of NREM sleep was not correlated with clinical factors such as, frequent nocturnal seizures, frequent generalized tonic clonic seizures, type of epilepsy and taking anticonvulsants. We conclude that the routine EEG used to evaluate epileptiform discharges in epileptic patients should include sleep recordings after partial sleep deprivation.

AbstractAbstract PDF
PURPOSE: The purpose of this study was a phantom study to measure the diffusion properties of water molecules by steady-state free precession diffusion-weighted imaging (SSFP-DWI) with a low b-value and to determine if this sequence might be useful for application to the evaluation of bone marrow pathology. MATERIALS AND METHODS: 1. The phantom study: A phantom study using two diffusion weighted sequences for the evaluation of the diffusion coefficient was performed. Three water-containing cylinders at different temperatures were designed: phantom A was 3degrees C, B was 23degrees C and C was 63degrees C. Both SSFP and echo planar imaging (EPI) sequences (b-value: 1000 s/mm2) were performed for comparison of the diffusion properties. The Signal to noise ratios (SNR) and apparent diffusion coefficient (ADC) values of the three phantoms using each diffusion-weighted sequence were assessed. 2. The Clinical study: SSFP-DWI was performed in 28 patients [sacral insufficiency fractures (10), osteoporotic lumbar compression fractures (10), malignant compression fractures (8)]. To measure the ADC maps, a diffusion-weighted single shot stimulated echo-acquisition mode sequence (650s/ mm2) was obtained using the same 1.5-T MR imager RESULTS: For the phantom study, the signal intensity on the SSFP as well as the classic EPI-based DWI was decreased as the temperature increased in phantom A to C. The ADC values of the phantoms on EPI-DWI were 0.13x10(-3) mm2/s in phantom A, 0.22x10(-3) mm2/s in B and 0.37x10(-3) mm2/s. in C. The SSFP can be regarded as a DWI sequence in view of the series of signal decreases. CONCLUSION: Bone marrow pathologies with different diffusion coefficients were evaluated by SSFP-DWI. All benign fractures were hypointense compared to the adjacent normal bone marrow where as the malignant fractures were hyperintense compared to the adjacent normal bone marrow.

PURPOSE: To evaluate the chemokine expression in children with a non-productive cough. MATERIALS AND METHODS: Six children with a non-productive cough who visited Yeungnam University Hospital were evaluated for the mRNA expression of interferon-gamma-inducible protein 10(IP-10), macrophage cationic protein 1 and 3 (MCP-1, 3), interleukin (IL)-8, regulated upon activation in normal T cells expressed and secreted (RANTES), eotaxin and growth-related oncogene-alpha (Gro-alpha) using the reverse transcription polymerase chain reaction. RESULTS: The chemokines IP-10 and MCP-3 were expressed in all samples. The chemokine RANTES was expressed in five cases, and IL-8 was expressed in three among them. However, eotaxin, Gro-alpha and MCP-1 were not expressed at all. The expression of chemokine MCP-3, RANTES and IL-8 were suppressed after the resolution of coughing in just one available case. CONCLUSION: The chemokines MCP-3, RANTES and IL-8 may contribute to airway inflammation in children with a non-productive cough, whereas IP-10 is of secondary importance in this condition.

BACKGROUND
Interpretative reporting is an important aspect of laboratory medicine. The large menu of laboratory tests available today makes it increasingly difficult for the non-specialist to order and interpret all laboratory tests. The aim of this study was to determine the usefulness of an expert system to interpret laboratory tests and help physicians order the appropriate tests. MATERIALS AND METHODS: In order to interpret laboratory tests, a rules-based expert system was developed. In this module, if-then rules were used to interpret the given test result patterns (e.g. urinalysis, anemia, hepatitis B virus, hypercholesterolemia, glucose, syphilis, and tumor markers) and select matching text elements. The system was used to evaluate 535 subjects who visited a health-check program. RESULTS: The overall abnormal rate was 50.5% in the expert system; 34% for cholesterol, 9.9% for urinalysis, 8.0% for anemia, 7.7% for thyroid function tests, 4.5% for tumor marker study, 4.7% for hepatitis virus antigen, 4.3% for serum glucose, and 1.1% for syphilis. CONCLUSION: These results indicate that the application of the expert system for the interpretation of laboratory tests may provide a useful method for the interpretation of reports. However more rules are needed for the application to in-patients.

AbstractAbstract PDF
BACKGROUND
Computer- and web-based simulation methods help students develop problem solving and decision making skills. In addition, they provide reality based learning to the student clinical experience with immediate medical feedback as well as repetitive training, on-site reviews and case closure. MATERIALS AND METHODS: Seventy-five third-year medical students participated in a two-week simulation program. The students selected four modules from eight modules as follows: airway and breathing 1, cardiac arrest 1, cardiac arrhythmia 1, and chest pain 1, and then selected the first case within each of the modules. After 2 weeks, a pass score was obtained and the data analyzed. The average pass score of over 70% was considered a passing grade for each module. If the student did not pass each module, there was no score (i.e., pass score was zero). In addition, when at least one of the four modules was zero, the student was not included in this study. RESULTS: Seventy-five students participated in the simulation program. Nineteen students were excluded based on their performance. The final number of students studied was 56 students (74.7%). The average scores for each module 1 to 4 were 86.7%, 85.3%, 84.0%, and 84.0%, and the average obtained pass score was 88.6 for the four modules in all 56 students. CONCLUSION: Medical simulation enabled students to experience realistic patient situations as part of medical learning. However, it has not been incorporated into traditional educational methodology. Here we describe the introduction and the development of various simulation modules and technologies for medical education.

AbstractAbstract PDF
BACKGROUND
This study was undertaken to evaluate the effectiveness of the Bonfils intubation fibrescope for cases of difficult tracheal intubation. MATERIALS AND METHODS: For patients with an ASA physical status 1 or 2 betwen the ages of 20-90, direct laryngoscopy was performed and the layngoscopic view graded according to the Cormack and Lehane classification. Forty patients with Cormack and Lehane grade 3 or 4 were intubated using the Bonfils intubation fibrescope. During intubation, the success rates for tracheal intubation, overall time to intubation, number of attempts and adverse effects were recorded. The Thyromental and sternomental distances were recorded after the orotracheal intubation. RESULTS: The success rates were significantly higher in Cormack and Lehane grade 3 (96.9%) patients compared to grade 4 (50%) (P<0.01). The time to intubation was significantly faster in patients with grade 3 compared to grade 4 (20 (10-49[7-300]) sec vs. 180 (31-300[10-300]) sec, P=0.01). The number of cases with a SpO2<90% was significantly lower in patients with grade 3 (3.1%) compared to grade 4 (50%) (P<0.01). CONCLUSION: In patients with Cormack and Lehane grade 3, tracheal intubation using the Bonfils intubation fibrescope appears to be an effective technique for the management of a difficult intubation. However, the Bonfils intubation fibrescope can not always be used for the management of a difficult intubation in grade 4 patients; for these patients other effective instruments should be considered for difficult intubations.

PURPOSE: It is well known that suspension microlaryngeal surgery produces marked increases in arterial blood pressure and heart rate. In this study, we evaluated the effects of 10% lidocaine preoperatively sprayed for attenuation of the perioperative hemodynamic response during suspension microlaryngeal surgery. MATERIALS AND METHODS: Fifty American Society of Anesthesiologists (ASA) class 1 patients scheduled for excision of a vocal polyp by suspension laryngoscopy were randomly divided into two groups (n=25 for each group). They were intubated without 10% lidocaine spray (control group) or given 1.5 mg/kg of 10% lidocaine sprayed onto the pharyngolaryngeal and intratracheal sites 90 sec prior to intubation (10% lidocaine group). Anesthesia was maintained using desflurane in O2/N2O 50%. The arterial blood pressure and heart rate were measured at preinduction (T0), 1 min (T1), 3 min (T2), 5 min (T3) after tracheal intubation, and 1 min (T4), 3 min (T5), 5 min (T6) and 10 min (T7) after the suspension laryngoscopy. RESULTS: In the 10% lidocaine group, the arterial blood pressure and heart rate at 1 (T1), 3 (T2) min after tracheal intubation and 1 (T4), and 3 (T5) min after suspension laryngoscopy were lower than the same measurements in the control group. CONCLUSION: 10% lidocaine sprayed onto the pharyngolaryngeal and intratracheal sites before intubation was an effective method for attenuation of the perioperative hemodynamic response during suspension microlaryngeal surgery.

AbstractAbstract PDF
BACKGROUND
The incidence of acute hepatitis A in adults has recently been increasing. This study was conducted to investigate the epidemiology and clinical characteristics of acute hepatitis A in Daegu province over the past 10 years. MATERIALS AND METHODS: We reviewed the medical records of 55 patients (male/female: 34/21), who were diagnosed with acute hepatitis A by confirmation of the IgM anti-HAV between January 1998 and June 2007. RESULTS: The mean age was 29.7+/-10.3 years (range; 17-65 years). The incidence was most common between March and June (56.1%), in the third and fourth decades of life (78.2%) and 90.9% (50/55) of the patients were diagnosed from 2003 to present. The common symptoms included anorexia, nausea or vomiting (69.1%), fever and chills (49.1%), myalgia (47.3%), weight loss (47.3%), fatigue (40.0%), abdominal pain (36.4%), diarrhea (9.1%) and pruritus (5.5%). The mean duration of hospital stay was 8.6+/-3.4 days (range; 3-20 days). The route of transmission was identified in only 11 patients (20.0%); 7 patients (12.7%) traveled (abroad or domestic), 2 patients (3.6%) ingested raw food and 2 patients (3.6%) had friends with acute hepatitis A. Fifty four patients recovered without complication; one patient developed fulminant hepatitis and recovered after a liver transplantation. CONCLUSION: The incidence of acute hepatitis A in adults is increasing. Because of the cost of treatment and potential for serious disease, persons, under 40 are recommened to have hepatitis A vaccination and confirmation of IgG anti-HAV.

AbstractAbstract PDF
BACKGROUND
Urinary tract infection (UTI) is common in children. The available gold standard methods for diagnosis, Tc-99m dimercaptosuccinic acid (DMSA) scan and computed tomography (CT) are invasive and expensive. This study was performed to assess the role of power Doppler ultrasound (PDU) for diagnosis of acute pyelonephritis (APN). MATERIALS AND METHODS: A prospective study was conducted in 25 children with aged 2 weeks to 5 years who were hospitalized with the first episode of febrile UTI suggesting acute pyelonephritis. All children were examined in the first 3-5 days of admission by PDU and Tc-99m DMSA scan. The comparison between PDU and DMSA scan was performed on the basis of patients. RESULTS: The sensitivity and specificity of PDU for the detection of affected kidneys were 38.1% and 50.0%, and the positive predictive value and negative predictive value were 61.9% and 50.0%, respectively. Vesicoureteral refluxes (VUR) were identified in 11 patients (44.4%) and 18 kidneys (36%). The PDU and DMSA scan showed a matching perfusion defect in 23.8% and 50.0% respectively. CONCLUSION: These data indicate the PDU has a relatively low sensitivity and specificity for differentiating APN from lower UTI but may be a complement tool to DMSA scan for the prediction of VUR in infants and children.

BACKGROUND
The aim of this study was to confirm the risk factors for low back pain and injury to improve the prevention and treatment of lower back pain. MATERIALS AND METHODS: An epidemiologic study of low back pain and injury was performed with questionnaires distributed to 471 women working at Yeungnam university hospital. The differences in low back pain and injuries among various hospital departments were analyzed by a one-way analysis of variance (ANOVA), and the relevant factors included in the questionnaire were determined by a factor analysis. RESULTS: The frequency of low back pain in women in the department of diet and in the maintenance department was higher than among the other departments. The frequency of low back pain was mainly related to the frequency of psychosomatic symptoms. In addition, the low back pain was partially related to the frequency of psychosomatic symptoms and partially related to the frequency of pushing during the workday. The degree of disability from low back pain was increased by lifting and hard physical work and was related to the frequency of psychosomatic symptoms and the degree of work dissatisfaction. The frequency of low back injury was increased by increased standing time during work and hard physical work. The frequency of low back injury was related to advancing age and in part to psychosomatic symptoms. CONCLUSION: Lower back pain and its associated complications are related to psychosomatic factors and type of work. Lower back injury is related to physiological factors such as age. For the prevention and treatment of lower back pain, a multidisciplinary approach is required.

AbstractAbstract PDF
BACKGROUND
The occurrence of atrial fibrillation after ablation of atrial flutter is clinically important. We investigated variables predicting this evolution in ablated patients without a previous atrial fibrillation history. MATERIALS AND METHODS: Thirty-six patients (Male=28) who were diagnosed as atrial flutter without previous atrial fibrillation history were enrolled in this study. Group 1 (n=11) was defined as those who developed atrial fibrillation after atrial flutter ablation during 1 year follow-up. Group 2 (n=25) was defined as those who has not occurred atrial fibrillation during same follow-up term. Echocardiogram was performed to all patients. We measured left atrial size, left ventricle end diastolic and systolic dimension, ejection fraction and left atrial volume index before and after ablation of atrial flutter. The differences of each variables were compared and analyzed between two groups. RESULTS: The preablation left ventricular ejection fraction (preLVEF) and postablation left ventricular ejection fraction (postLVEF) are 54+/-14%, 56+/-13% in group 1 and 47+/-16%, 52+/-13% in group 2. The differences between each two groups are statistically insignificant (2.2+/-1.5 in group 1 vs 5.4+/-9.8 in group 2, p=0.53). The preablation left atrial size (preLA) and postablation left atrial size (postLA) are 40+/-4 mm, 41+/-4 mm in group1 and 44+/-8 mm, 41+/-4 mm in group 2. The atrial sizes of both groups were increased but, the differences of left atrial size between two groups before and after flutter ablation were statistically insignificant (0.6+/-0.9mm in group 1 vs -3.8+/-7.4 mm in group 2, p=0.149). The left atrial volume index before flutter ablation was significantly reduced in group 1 than group 2 (32+/-10 mm3/m2, 35+/-10 mm3/m2 in group 1 and 32+/-10 mm3/m2, 29+/-8 mm3/m2 in group 2, p<0.05). CONCLUSION: The difference between left atrial volume index before and after atrial flutter ablation is the robust predictor of occurrence of atrial fibrillation after atrial flutter ablation without previous atrial fibrillation.

AbstractAbstract PDF
BACKGROUND
The prone position is often used for operations involving the spine and provides excellent surgical access. The complications associated with the prone position include ocular and auricular injuries, and musculoskeletal injuries. In particular, the prone position during general anesthesia causes hemodynamic changes. To evaluate the cardiovascular effects of the prone position in surgical patients during general anesthesia, we investigated the effects on hemodynamic change of the prone position with the Jackson spinal surgery table. MATERIALS AND METHODS:Thirty patients undergoing spine surgery in the prone position were randomly selected. After induction of general anesthesia, intra-arterial and central venous pressures (CVP) were monitored and cardiac output was measured by NICO(R). We measured stroke volume, cardiac index, cardiac output, mean arterial pressure, heart rate, CVP and systemic vascular resistance (SVR) before changing the position. The same measurements were performed after changing to the prone position with the patient on the Jackson spinal surgery table. RESULTS: In the prone position, there was a significant reduction in stroke volume, cardiac index and cardiac output. The heart rate, mean arterial pressure and CVP were also decreased in the prone position but not significantly. However, the SVR was increased significantly. CONCLUSION: The degree of a reduced cardiac index was less on the Jackson spinal surgery table than other conditions of the prone position. The reduced epidural pressure caused by free abdominal movement may decrease intraoperative blood loss. Therefore, the Jackson spinal surgery table provides a convenient and stable method for maintaining patients in the prone position during spinal surgery.

AbstractAbstract PDF
BACKGROUND
An acceleration or deceleration of the heart rate (HR), which reflects autonomic effects, is observed before the onset of paroxysmal atrial fibrillation (PAF). The purpose of this study was to assess the discrepancy in the autonomic interactions before the onset of PAF for different patterns of change in the HR. MATERIALS AND METHODS: From 105 Holter tapes with the PAF recorded, 55 episodes (42 patients, 34 men, 58+/-12 years) of PAF (>5 min), preceded by a sinus rhythm for more than 1 hour, were selected and submitted to time-domain and frequency-domain HR variability analyses. Fifty-five episodes were divided into 2 groups: group A PAF (n=30) with acceleration of the HR during the last 2 minutes before the PAF and group B (n=25) with deceleration of the HR. RESULTS: A significant linear decrease in the mean R-R interval was observed in group A (924+/-30 to 835+/-28 ms, P=0.001) and an increase from 831+/-32 to 866+/-31 ms in group B PAF episodes (P=0.046). In the frequency-domain analyses, the LF/HF ratio exhibited a progressive linear increase before the PAF in group A (P=0.005). The HF normalized units (HFnu) and natural logarithm-transformed HF (lnHF) values decreased from 30.8+/-4.0 to 16.1+/-1.8 (P=0.003) and 4.49+/-0.25 to 4.07+/-0.22 (P=0.001), respectively. Contrary to the results in group A, a significant increase in the HF components (HFnu and lnHF) (from 22.6+/-3.2 to 30.2+/-4.0, P=0.005, and 4.27+/-0.27 to 4.75 0.33, P=0.001, respectively) and a resultant decrease in the LF/HF ratio were observed in group B PAF episodes. No significant changes were observed in the LF components in either PAF group. CONCLUSION: Autonomic stimuli leading to an acceleration or deceleration of the HR before the onset of AF are due to parasympathetic modulation. Parasympathetic modulation plays a key role in the initiation of PAF

AbstractAbstract PDF
BACKGROUND
The safety and efficacy of trabeculectomy with Mitomycin C (MMC) for surgical treatment in aphakic and pseudophaic eyes were retrospectively evaluated. MATERIALS AND METHODS: The authors reviewed 51 eyes of 45 patients who had been followed up for at least 6 months after trabeculectomy using MMC for aphakic and pseudophakic eyes. The success rate and complications were analyzed. The success criteria included intraocular pressures of 21 mmHg or less with or without glaucoma medications and no loss of light perception. Surgical failure was defined as a postoperative loss of light perception in patients with preoperative vision better than light perception, additional glaucoma surgery, or phthisis bulbi in patients with preoperative vision of no light perception. RESULTS: The average follow up period was 27.7 months and the intraocular pressure was controlled under 21 mmHg in 36 eyes of 51 (70.6%) after the procedure with or without medication for glaucoma. Using the Kaplan-Meier survival analysis, the cumulative success rate at the 3-, 6-, 12-, 24- and 36-month intervals were 98.0%, 94.1%, 91.9%, 83.4% and 75.5%, respectively. The complications observed were hyphema (4 eyes), serous choroidal detachment (4 eyes), hypotony (3 eyes), and endophthalmitis (1 eye). CONCLUSION: Trabeculectomy using Mitomycin C for the treatment of aphakic and pseudophaic eyes was safe and effective.

AbstractAbstract PDF
PURPOSE: This study was conducted to assess the surgical outcomes of limbal lensectomy with or without anterior vitrectomy for the management of lens subluxation. MATERIALS AND METHODS: The medical records of 20 consecutive patients (33 eyes) with lens subluxation who had undergone limbal lensectomy with or without anterior vitrectomy from February 1999 to January 2004 were retrospectively reviewed. RESULTS: All the patients, except one high axial myopic patient, were implanted with scleral sutured posterior chamber intraocular lens. We evaluated the preoperative, postoperative visual acuity and postoperative complications and compared the results in group I (limbal lensectomy with anterior vitrectomy, 27 eyes) to those in group II (limbal lensectomy without anterior vitrectomy, 6 eyes). The preoperative best-corrected visual acuity was 0.21 and postoperative best-corrected visual acuity was improved by 2 lines or more in all 27 eyes in group I, and in 5 eyes in group II (p>0.05). The most frequent postoperative complication was intraocular lens dislocation in four eyes (14.8%) in group I alone. No retinal detachment occurred in either group, even in patients with high myopia. CONCLUSION: Limbal lensectomy without anterior vitrectomy improved visual acuity similarly to limbal lensectomy with anterior vitrectomy without significant increase of postoperative complications. This results of this study suggest that anterior vitrectomy is not necessarily required for the management of lens subluxation.

BACKGROUND
Obesity is the most common nutritional disorder in Western society as well as in Korea. Obesity results from a combination of genetic, environmental, and behavioral factors. MATERIALS AND METHODS: In an attempt to investigate the association of obesity with its candidate genes, beta3 adrenergic receptor (beta3AR) and uncoupling protein 2 (UCP2), we analyzed polymorphisms of beta3AR Trp64Arg and UCP2 -866G/A by PCR-RFLP analysis and the obesity-related phenotypes, including body mass index (BMI), fasting glucose concentration, and plasma lipid profiles in 750 subjects. RESULTS: The Trp64Arg polymorphism in the beta3AR gene was not statistically associated with the BMI. The UCP2 -866G/A polymorphism was significantly higher in obese than in non-obese subjects (P<0.05). However, the UCP2 -866A/A polymorphism was higher in the non-obese subjects. CONCLUSION: These results suggest that the UCP2 -866G/A polymorphism might be more useful for the prediction of obesity and obesity-associated diseases in Korean patients than the beta3AR Trp64Arg polymorphism.

AbstractAbstract PDF
PURPOSE: Bone morphogenetic proteins (BMPs) play an important role in the formation of cartilage and bone, as well as regulating the growth of chondroblasts and osteoblasts. In this study, we investigated whether recombinant human BMP adenoviruses are available for ex vivo gene therapy, using human fibroblasts and human bone marrow stromal cells in an animal spinal fusion model. MATERIALS AND METHODS: Human fibroblasts and human bone marrow stromal cells were transduced with recombinant BMP-2 adenovirus (AdBMP-2) or recombinant BMP-7 adenovirus (AdBMP-7), referred to as AdBMP-7/BMSC, AdBMP-2/BMSC, AdBMP-7/HuFb, and AdBMP-2/HuFb. We showed that each cell secreted active BMPs by alkaline phosphatase staining. Since AdBMP-2 or AdBMP-7 tranducing cells were injected into the paravertebral muscle of athymic nude mice, at 4 weeks and 7 weeks, we confirmed that new bone formation occurred by induction of spinal fusion on radiographs and histochemical staining. RESULTS: In the region where the AdBMP-7/BMSC was injected, new bone formation was observed in all cases and spinal fusion was induced in two of these. AdBMP-2/BMSC induced bone formation and spinal fusion occurred among one of five. However, in the region where AdBMP/HuFb was injected, neither bone formation nor spinal fusion was observed. CONCLUSION: The osteoinductivity of AdBMP-7 was superior to that of AdBMP-2. In addition, the human bone marrow stromal cells were more efficient than the human fibroblasts for bone formation and spinal fusion. Therefore, the results of this study suggest that AdBMP-7/ BMSC would be the most useful approach to ex vivo gene therapy for an animal spinal fusion model.

AbstractAbstract PDF
BACKGROUND
Acute renal failure is one of the leading causes of postoperative morbidity and mortality. The purpose of this study was to determine the risk factors that are associated with acute renal failure after colorectal surgery. MATERIALS AND METHODS: Five hundred seventy patients who operated colorectal surgery at the Yeungnam University Medical Center over three years from 2004 to 2006 were enrolled in this study. The effects of gender, age, ASA classification, concomitant disease, surgery type and duration, reoperation, urogenital manipulation, medication, hypotension, hypovolemia, transfusion, and postoperative ventilatory care on the occurrence of acute renal failure after colorectal surgery were studied. RESULTS: The major risk factors of acute renal failure after colorectal surgery were age of patients (P=0.003), ASA classification (P<0.001), concomitant disease (P<0.001), duration of the time surgery (P=0.034), reoperation (P=0.001), use of intraoperative diuretics (P=0.005), use of postoperative diuretics (P<0.001), intraoperative hypotension (P=0.018), intraoperative transfusion (P<0.001), postoperative transfusion (P<0.001), and postoperative ventilatory care (P=0.001). CONCLUSION: Multiple factors cause synergistic effects on the development of acute renal failure after colorectal surgery. Therefore, efforts to reduce the risk factors associated with acute renal failure are needed. In addition, intensive postoperative care should be provided to all patients.

AbstractAbstract PDF
BACKGROUND
This study investigated and analyzed the life style of male white-collar workers and their perception of obesity to determine how to improve eating habits and prevent obesity. MATERIALS AND METHODS: Using the questionnaires distributed to and collected from 300 male white-collar workers in Daegu, the survey was conducted from December 20, 2005 to February 28, 2006. Two hundred sets of collected questionnaires were used for the analysis, and SPSS WIN 12.0 was employed to analyze the data. RESULTS: Forty-two percent of subjects had weights ranging between 71 kg and 80 kg; 39.5%, weighted between 61 kg and 70 kg. The waist measurements of 64.5% of all respondents were between 32 and 34 inches. The lifestyle questions found that 54% of respondents were smokers and 88.5% drank alcohol. In addition, 62.5% of all respondents reported doing exercise, whereas 37.5% reported no exercise. CONCLUSION: The height and weight of 200 respondents were used to calculate the body mass index (BMI). Only 31.6% had a normal BMI, whereas 32% were found to be overweight, a condition likely to lead to obesity. Meanwhile, 36.5% of respondents were obese or morbidly obese.

AbstractAbstract PDF
BACKGROUND
The main aim of this study was to analyze the factors that could be used to predict job satisfaction of assistant nurses in general hospitals. MATERIAL AND METHODS: This study was based on a survey of assistant nurses in the Daegu region from January 1, 2006 to January 31, 2006. Originally 300 questionnaires were distributed and among them 291 were completed. The data was collected and used for the statistical analysis. Descriptive and inferential statistics, such as the frequency, t-test and one-way ANOVA were used for the analysis. RESULTS: Among the respondents, the average score for job satisfaction was lowest in the university-trained nurses and highest in the nurses who had only graduated from high school. CONCLUSION: The working conditions, work place and motivation are significantly associated with job satisfaction. In particular, there was lower job satisfaction in those nurses who wanted to change their occupation.

AbstractAbstract PDF
BACKGROUND
After sinus surgery, airway dryness is made worse because patients breathe by mouth. Anticholinergic agents have antisialogogue effects. The airway dryness that occurs after surgery is severe and can increase the incidence of postoperative sore throat. MATERIALS AND METHODS: One-hundered patients who were scheduled for endoscopic sinus surgery(ESS) were divided into four groups. Each group was premedicated with glycopyrrolate or had no premedication and reversed with glycopyrrolate or atropine. After the surgery the patients were asked about a sore throat and hoarseness postoperatively after 1h, 6h, 12h, 24h, and 48hours, respectively. RESULTS: The incidence of postoperative sore throat and hoarseness was not significantly different among the four groups at any time. CONCLUSION: The severity of complications after ESS was low and subsided within 24 hours. Therefore, the use of anticholinergic agents does not need to be limited.

AbstractAbstract PDF
Angiomatoid fibrous histiocytoma is a rare soft tissue tumor that generally affects children and young adults. We report a case of angiomatoid fibrous histiocytoma in an 11-year-old boy who complained of a back mass for 3 years. Surgical excision was performed. The excised specimen showed a 4.0 x 3.6 x 3.0 cm, well circumscribed, grayish white tumor, with multicystic changes. Histological examination showed proliferation of spindle or round shaped tumor cells. There was a dense fibrous pseudocapsule with prominent chronic inflammatory cell infiltrates.

AbstractAbstract PDF
Ornithine transcarbamylase (OTC) deficiency is the most common inborn error of urea cycle metabolism; it is inherited in an X-linked manner. The OTC catalyzes the third step of the urea cycle, the conversion of ornithine and carbamyl phosphate to citrulline. Deficiency of OTC leads to the accumulation of ammonia, causing neurological deficits. In most affected hemizygote males, OTC deficiency manifests as hyperammonemic coma that often leads to death in the newborn period, and those who recover from the coma may be neurologically impaired due to the sequelae of the hyperammonemic encephalopathy. In some, late-onset manifestations develop. We report a male neonate with early onset OT deficiency that had apnea and was comatous. On mutation analysis using DNA sequencing after polymerase chain reaction (PCR) amplification of the 10 exons, deletions of 10 bases in codon 285, causing a frame shift was detected in exon 8. The mother and a sister were diagnosed as female carriers. Therefore, genetic counseling and the risk assessment could be provided to the family.

AbstractAbstract PDF
Solar retinopathy is a rare but well-recognized clinical entity of macular damage, caused by viewing a solar eclipse or direct sun gazing. A 21-year-old man gazed at the sun for approximately thirty seconds at noon using a monocular telescope with his left eye. Forty-eight hours after sun gazing, the patient experienced symptoms of blurred vision and central scotoma in the left eye. Eight months after sun gazing, the visual acuity decreased from 1.0 to 0.1 in the left eye and the fundus examination showed a round, yellowish-white discoid lesion at the left fovea. Fluorescein angiography showed an early window defect in the fovea of the left eye, that persisted without size change during the late phase resulting from atrophy of the retinal pigment epithelium. A small, central scotoma of the left eye was also found in the visual field test. The visual acuity was unchanged at the end of a one-year follow-up period.

AbstractAbstract PDF
Varicella is a contagious infection in childhood disease typically affecting children aged 2-8 years and usually follows benign outcome. In the adult, clinical presentation is more severe and more commonly associated with complications. Varicella pneumonia, although rare, is a potentially life-threatening complication that should be suspected in any adult with varicella and respiratory symptoms. We report a case of varicella pneumonia in immunocompetent patient. The characteristic radiographic findings consisted of diffuse scattered coarse nodular infiltrations, less than 1cm sized, with ground glass opacity and consolidation in both lung fields. The patients was started on intravenous acyclovir. The chest radiograph performed 2 weeks later showed complete resolution of the pulmonary lesions.

AbstractAbstract PDF
Laryngo-tracheal perforation caused by the use of a stylet during tracheal intubation is a rare complication. We present a case of subcutaneous emphysema and connective tissue inflammation after tracheal intubation. The patient was a 41-year-old male undergoing general anesthesia for an appendectomy. The intubation was difficult during laryngoscopy (Cormack-Lehane Grade III). An assistant provided an endotracheal tube with a stylet inside while the laryngoscope was in place. During intubation, a short, dull sound was heard with a sudden loss of resistance after the distal tip of the endotracheal tube passed the rima glottis. A sonogram and computerized tomography revealed subcutaneous emphysema from the neck to the upper mediastinum and fluid collection between the trachea and the thyroid. This lesion appeared to have been caused by the protruded, loose stylet. Anesthesiologists should be aware of the damage a loose stylet protruding beyond the tip of the endotracheal tube can cause.
