PURPOSE: We performed this study to evaluate the alterations in renal function for patients with ileal conduit and ileal orthotopic neobladder MATERIALS AND METHODS: From January 1999 to June 2004, 48 patients who had undergone radical cystectomy with urinary diversion were included in our study. The patients were divided into two groups according to the types of urinary diversion. One group consisted of 29 patients with ileal conduit and the other group consisted of 19 patients with ileal W neobladder. The mean age of the ileal conduit group and the ileal W neobladder group were 65.6+/-9.9 years and 60.8+/-8.3 years, respectively. The preoperative and postoperative blood urea nitrogen/creatinine (BUN/Cr) levels, postoperative complications and postoperative GFR, as measured by (99m)Tc-DTPA scans, were compared between the two groups. RESULTS: For the postoperative complications, stricture at the ureterovesical anastomosis site occurred in 1.7% (1/58 renal units) of the ileal conduit group and in 10.5% (4/38 renal units) of the ileal W neobladder group. Acute pyelonephritis occurred in 5.2% (3/58 renal units) of the ileal conduit group and in 5.3% (2/38 renal units) of the ileal W neobladder group. The pre- and postoperative serum BUN/Cr levels were 20.8/1.3 and 24.8/1.6, respectively, in the ileal conduit group, and 17.2/1.1 and 18.8/1.2, respectively, in the ileal W neobladder group. There were no statistical significant differences between the pre- and postoperative changes of the serum BUN/Cr levels for both groups. The GFR, as measured by (99m)Tc-DTPA scans, were 77.6 and 78.7ml/ min/1.73m2 in the ileal conduit group and the ileal W neobladder group, respectively. There were no statistical significant differences between the two groups. CONCLUSIONS: There were no significant differences in renal function between the ileal conduit and ileal W neobladder.

OBJECTIVES: OSAS (obstructive sleep apnea syndrome) is a common disorder and its consequences are often serious. It is important to detect the disorder early in the course for proper treatment. This study is to grasp the snoring clinic visitors' knowledge level of OSAS. METHODS: One hundred and seventy-nine visitors at the of snoring clinic of Seoul National University Hospital were surveyed by questionnaire about reasons of visit and knowledge of treatment methods of snoring and OSAS, diagnostic method, OSAS-related symptoms, and complications. RESULTS: Most of the respondents (89.4%) "have already heard about OSAS" and the major sources of information was the mass media (58.1%) such as television and radio. More than half (60.3%) were aware that snoring is closely related to OSAS. More than half (59.8%) recognized that a nocturnal polysomnograpy was necessary for proper diagnosis. Two thirds (67%) of the respondents noted surgery as a treatment for snoring. More than half (55.9%) answered that they would follow the doctor's advice on the treatment choice. Only 12.3% of respondents "have heard about nCPAP". No one chose nCPAP (nasal continuous positive airway pressure) as a treatment for either snoring or OSAS. About one third (34.6%) of the respondents were aware that OSAS is related to hypertension. Only 12.8% noted that OSAS is related to diabetes mellitus. CONCLUSION: Visitors at the snoring clinic were found to have substantially limited knowledge of health risks and proper treatments of OSAS. We suggest that it is crucially important to educate patients and offer easy-to-understand information on snoring and OSAS. We predict that provision of educaiton and information to patients and general public will faciliate the diagnosis and treatment of snoring and OSAS and reduce the related disorders such as hypertension, stroke, and diabetes mellitus.

In order to prepare the fundamental data for preventing the hazardous effects at toluene exposure in many kinds of industry, the authors determined the level of urinary hippuric acid on 592 toluene exposed women(exposed group) and 102 unexposed women(control group) in Pusan area, from April 1 to October 31, 1986. Hippuric acid was measured by high performance liquid chromatography. The results were summarized as follows; 1. The mean value of urinary hippuric acid concentration of the control group was 0.44+/-0.21g/l(0.11-0.89g/l). The distribution of urinary hippuric acid concentration of the control group was not fit to the normal distribution. 2. The mean value of urinary hippuric acid concentration of the exposed group was 1.56+/-0.95g/l(0.44-4.57g/l). The distribution of urinary hippuric acid concentration of control group was not fit to the normal distribution. 3. The urinary hippuric acid concentration by age group was not statistically significant in the control group, but in the exposed the urinary hippuric acid concentration was highest in women between 20-29 years old(1.71+/-0.95g/l) and was statistically significant(p<0.01). 4. The urinary hippuric acid concentration by duration of working hours was not statistically significant(p>0.1).

A frequent dilemma facing the anesthesiologist is the patient with respiratory tract symptoms. The risks of anesthesia and surgery in these patients have not been clearly established. We present a case in which a potentially serious respiratory complication had arisen. The patient had symptoms of coughing and mucous production. She was a heavy smoker. However, there was no history of pulmonary disease. This report describes a patient who developed left upper lobar collapse after induction of general anesthesia and tachydysrhythmia resulting in ventricular tachycardia and myocardial ischemia.

PURPOSE: To study choroidal thickness and its topographic profile in normal eyes using 3D OCT-1000 spectral domain optical coherence tomography and the correlation with age and refractive error. METHODS: Fifty-seven eyes (45 individuals) with no visual complaints or ocular disease underwent horizontal and vertical line scanning using 3D OCT-1000. The definition of choroidal thickness was the vertical distance between the posterior edge of the hyper-reflective retinal pigment epithelium and the choroid/sclera junction. Choroidal thickness was measured in the subfoveal area at 500 microm intervals from the fovea to 2,500 microm in the nasal, temporal, superior, and inferior regions. The spherical equivalent refractive error was measured by autorefractometry. Statistical analysis was used to confirm the correlations of choroidal thickness with age and refraction error. RESULTS: The mean age of the 45 participants (57 eyes) was 45.28 years. Detailed visualization of the choroid for measuring its thickness was possible in 63.3% of eyes. The mean subfoveal choroidal thickness was found to be 270.8 microm (standard deviation [SD], +/-51 microm), in horizontal scanning and 275.0 microm (SD, +/-49 microm) in vertical scanning. The temporal choroidal thickness was greater than any 500 microm interval in corresponding locations, and there was no significant difference between the superior and inferior choroid as far as 2,000 microm from the fovea. Age and refractive error were associated with subfoveal choroidal thickness in terms of regression (p < 0.05). CONCLUSIONS: Choroidal thickness in normal Korean eyes can be measured using 3D OCT-1000 with high resolution line scanning. The topographical profile of choroidal thickness varies depending on its location. Age and refractive error are essential factors for interpretation of choroidal thickness.

PURPOSE: To compare mini-mental state examination (MMSE) score between glaucoma group and normal control group and to evaluate the correlation between MMSE score and spectral domain-optical coherence tomography (SD-OCT) values in both groups. METHODS: This prospective study includes thirty glaucoma patients (eleven primary open angle glaucoma and nineteen normal tension glaucoma) and thirty normal controls. Retinal nerve fiber layer (RNFL) and Ganglion cell-inner plexiform layer (GC-IPL) thickness were measured with SD-OCT, and the average values of both eyes were used. The cognitive function was evaluated with MMSE by a single examiner. RESULTS: The mean MMSE scores of glaucoma group and normal group were 26.07 ± 2.95, and 27.00 ± 1.68 respectively (p = 0.137). MMSE score of less than 24 only showed in glaucoma group. MMSE score and RNFL thickness showed statistically no signifance in correlation (R² = 0.236; p = 0.070), however, MMSE score and GC-IPL showed statistically significant correlation (R² = 0.256; p = 0.048). CONCLUSIONS: Glaucoma patients tend to show low cognitive function even though the correlation between glaucoma patient and low cognitive function was not statistically significant. Therefore, the aspect of cognitive depression should be concerned, when facing glaucoma patients.

The purpose of this study was to assess the comorbid axis-II disorders of obsessive compulsive disorder(OCD) patients and to investigate the relationship between symptoms of OCD and the comorbid personality traits. The subjects were 59 patients who met DSM-IV criteria for obsessive-compulsive disorder and 32 normal controls. All subjects completed Personality Disorder Questionnaire-IV(PDQ-IV). The patients completed Beck Depression Inventory(BDI) and Beck Anxiety Inventory(BAI), and were rated with Yale-Brown Obsessive Compulsive Scale(YBOCS). The results were as follows. 1) The OCD patients showed significantly higher prevalence of avoidant, depresssive and borderline personality disorder(p<0.01) compared to controls. 2) The BAI score had significant effect on the avoidant personality score(t=3.23, p<0.003). The BDI score had significant effect on the depressive personality score(t=3.08, p=0.004). The YBOCS(t=2.10, p=0.043) and BAI(t=2.60, p=0.014)scores had significant effects on the borderline personality score. We found that OCD patients had higher prevalence of avoidant, depressive, and borderline personality disorders. We also found that obsessive-compulsive symptoms have significant effect on the severity of borderline personalty traits. We suggest that it would be very helpful to consider Axis-II disorders for managing patients with obsessive-compulsive disorder.

BACKGROUND: With the rapid aging of the Korean population and the steady decrease in the donor population during the past few years, there is a need for measures to ensure balance between blood demand and supply. The trends of the donor population and donor deferral during the past eleven years (1995~2005) were examined to obtain basic data to be used in donor management policy-making. METHODS: Data on the donor population, presenting donors, deferred donors and the reasons for deferral were examined by searching the Blood Information Management System (BIMS) and Annual reports of the Korean Red Cross. RESULTS: The number of presenting donors increased until 2003. However, the actual number of eligible donors has been decreasing since 1999 due to the increase in donor deferral. By enforcing donor eligibility criteria, the donor deferral rate in 1998 increased by 75.2% compared with the previous year, and the deferral rate was 21% in 2005. A low blood specific gravity (SG) was the most common reason for deferral, and more than 90% of those deferred due to a low SG were women. CONCLUSION: In order to assure an adequate donor base, policies should not only target donor recruitment but also the management of deferred donors. The adequacy of currently applied donor eligibility criteria should be reevaluated, and deferred donors should be counseled about their reason for deferral in order to encourage donation. Furthermore, the hemoglobin criteria for women should be reconsidered.

PURPOSE: To investigate the relationship between photoreceptor inner/outer segment (IS/OS) integrity and macular sensitivity after epiretinal membrane (ERM) surgery using spectral-domain optical coherence tomography combined with microperimetry. METHODS: 20 eyes of 20 patients with idiopathic ERM who underwent pars plana vitrectomy for ERM removal were prospectively reviewed. The IS/OS defect diameter, BCVA, macular sensitivity, and fixation stability were measured using spectral-domain optical coherence tomography combined with microperimetry. The correlation of these factors was analyzed. RESULTS: The macular sensitivity improved after successful ERM surgery (p < 0.001), but the IS/OS defect diameter has not improved. The preoperative and postoperative macular sensitivity were negatively correlated with preoperative IS/OS defect diameter (p = 0.035, p = 0.006). The fixation stability was not correlated with preoperative IS/OS defect diameter. CONCLUSIONS: Macular sensitivity showed significant correlation with IS/OS defect diameter. Macular sensitivity is vital functional parameter allows subjective quantification of the retinal function and reflects morphologic changes.

Symptomatic primary heart tumors are rare in newborn. Cardiac rhabdomyoma is the most common lesion of the primary heart tumors and over half of them are related to kthe tuberous s clerosis. We described a case of cardiac rhabdomyoma, in a 2 day-old female newborn who presented with dyspnea and cyanosis. A 2D Echocardiogram demonstrated two masses; one is in the rt. ventricle and another is in the interventricular septum. Additional cardiac masses and cerebral tubers and subependymal giant cell astrocytoma were found at autopsy.
