PURPOSE: To evaluate the characteristics of CT findings in differential diagnosis of cervical lymphadenopathy. MATERIALS AND METHODS: We evaluated CT findings of histopathologically proved 32 cases of tuberculous lymphadenitis, 12 cases of nodal lymphoma, 29 cases of metastasis from March 1986 to Dec. 1992, retrospectively. We analyzed age and sex distribution, location of lymphadenopathy, internal nodal density, feature of contrast enhancement, extracapsular spread and nodal calcification. RESULTS: Tuberculous lymphadenitis was more preponderant in young female (mean;32) and CT showed internal low density(91%) with irregular thick marginal enhancement(46.9%), predilection for spinal accessory node(71.9%), and nodal calcification(5/32). Nodal lymphoma showed predilection for internal jugular chain (100%) and had conglomerated homogeneous internal node structures(83%). Metastasis showed old male preponderance (mean :52 years), predilected at internal jugular chain(89.7%),internal low density(93.3%) with regular thin marginal enhancement(44.8%), extracapsular spread(41.4%), and nodal calcification(2 cases of nodal metastasis of papillary type thyroid cancer). CONCLUSION: We concluded that CT evaluation of the chracteristics of lymphadenopathy is helpful for differential diagnosis of cervical lymphadenopathy.

PURPOSE: Bipolar energy has recently been used for transurethral resection of bladder tumor (TURBT). Although this modality is thought to be safe, there are some controversies concerning the pathologic accuracy of the biopsy specimens. We compared clinical efficacy, safety, and pathologic characteristics of deep biopsy specimens between bipolar and monopolar devices. MATERIALS AND METHODS: From January 2002 to June 2007, a total of 115 patients underwent TURBT with deep biopsy with the use of bipolar (bipolar group, n=64) or monopolar (monopolar group, n=51) devices. We retrospectively analyzed tumor size, tumor number, urine cytology, perioperative blood loss (postoperative changes in hemoglobin levels), complications, duration of catheterization, duration of hospitalization, pathologic stage, WHO grade, deep biopsy specimen thickness, and grade of thermal damage. RESULTS: There were no statistical differences in tumor size, tumor number, urine cytology, complications, duration of hospitalization, pathologic stage, or WHO grade between the two groups. Postoperative changes in hemoglobin levels were significantly lower in the bipolar group (p=0.038), and the duration of catheterization was shorter in the bipolar group (p=0.026). The deep biopsy specimen thickness was significantly thinner in the bipolar group (2.25+/-0.94 mm vs. 3.02+/-1.39 mm, p<0.05). The grade of thermal damage was not statistically different between the two groups (p=0.862). CONCLUSIONS: In terms of clinical efficacy and safety, bipolar TURBT is comparable to monopolar TURBT, having advantages in perioperative blood loss and duration of catheterization. In addition, pathologic changes in deep biopsy after bipolar and monopolar TURBT are similar. Bipolar TURBT can be properly used for bladder tumors without pathologic error.

OBJECTIVES: This study was conducted for development of the Korean version of the Posttraumatic stress disorder (PTSD) Checklist civilian version (PCL-C) by evaluating its reliability and validity for the North Korean defectors population. METHODS: A total of 69 North Korean defectors participated in this study. All patients were recruited from the psychiatric outpatient or inpatient ward. We categorized the participants into two groups according to the Clinician-Administered PTSD Scale (CAPS) diagnosis of PTSD (PTSD, n=32 ; Non-PTSD, n=37). All Subjects completed psychometric assessments, including the PCL-C, Minnesota Multiphasic Personality Inventory (MMPI-PTSD), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI). RESULTS: Findings provided support for psychometric properties of the Korean version of the PCL-C. The PCL-C showed good internal consistency (Cronbach alpha=0.93), and a significantly positive correlation with CAPS and MMPI-PTSD (r=0.47, r=0.61, respectively). The optimal cutoff point of PCL-C for the North Korean defectors was at a total score of 56 with sensitivity and specificity of 0.88, and 0.50, respectively. CONCLUSION: Overall, the Korean version of the PCL-C appears to be a valid and reliable measure of PTSD symptoms among the North Korean defectors.

The internal jugular and subclavian veins are considered as satisfactory intravenous routes for rapid blood and fluid replacement. To determine whether these venous pressures can be used as reliable guides for central venous pressure monitoring, simultaneous measurements of the Rt. internal jugular venous pressure and central venous pressure (CVP), or Rt. subclavian venous pressure and CVP using long 14 gauge catheter were made in 20 patients undergoing cardiac anesthesia. The results were as follows: l. Each mean value of the Rt. internal jugular venous pressure and CVP was 10.64+/-5.43 cm H2O and 10.05+/-5.55cm H2O (Mean+/-SD) respectively in first 10 patients. Pressure difference was 0.59+/-0.39cm H2O (p<0.005). 2. Each mean value of the Rt. subclavian venous pressure and VP was 7.77+/-3.37 cm H 0 and 7.05+/-3.49cm H2O (Mean+/-SD) respectively in second 10 patients. Pressure difference was 0.73+/-0.59cm H2O (p<0.005). 3. There were significant correlations between Rt. internal jugular venous pressure and CVP (r=0. 99, p<0.005) as well as between Rt. subclavian venous pressure and CVP (r=0.98, p<0.005). The results suggest that Rt. internal jugular or subclavian vein catheterized with short intravenous catheter during Anesthesia can be used as effective and reliable guides for CVP monitoring because pressure differences with CVP were small and consistant.

PURPOSE: The purpose of this study was to evaluate the CT findings of thyroglossal duct cysts MATERIALS AND METHODS: Sixteen patients with pathologically proved thyroglossal duct cysts were included in the study. CT scans were assessed'retrospectively for shape, size, location, density of the central portions, septations, rim enhancement, changes in the adjacent fascial planes and investment within the strap muscles in the infrahyoid cysts. RESULT: Thirteen cases of thyroglossal duct cysts were seen as round or oval cystic masses, two cases of them were seen as irregular-shaped Iobulated cystic masses, and one case was seen as ovoid soft tissue mass. The cysts were from 1.4 to 5.7cm in diameter(mean, 2.6cm). The cyst was infrahyoid in 15 cases and suprahyoid in one case. The cyst was located in midline in eight cases, off midline in four cases, and both midline and off midline in four cases. The density of the central portions ranged from 15 to 82HU(mean, 32HU). Septations were noted in four cases. Rim enhancement was seen in 14 cases(93%), and heterogenously enhancing soft tissue mass was seen in one case. In four cases, abnormal fascial planes were observed. All but one of the infrahyoid cysts(14/15) were embedded within the strap muscles, and one case of them was located anteriorly to strap muscles. CONCLUSION: CT permits one to make the diagnosis a thyroglossal duct cyst with a high degree of accuracy, as it can differentiate thyroglossal duct cysts from the other anterior neck masses by their typical location, characteristic morphology, and investment within the strap muscles.

OBJECTIVES: The most common chromosomal abnormality contributing to recurrent abortion is the balanced chromosomal translocation. However the exact incidence of fetal losses are still unknown. The objectives of this study were to evaluate the incidence of fetal chromosomal abnormalities and outcome of pregnancy in recurrent miscarriage couples with balanced translocation. DESIGN: A retrospective analysis of recurrent spontaneous abortion patients with balanced chromosomal translocation. MATERIALS AND METHODS: Cytogenetic analysis was performed in 56 couples with history of recurrent abortions from 1995 to 1999. The use of high resolution banding technique and fluorescent in situ hybridization (FISH) in the chromosomal analysis has made the precise evaluation of chromosome aberrations. RESULTS: Among 56 couples, 42 patients had reciprocal translocation and 14 had Robertsonian translocation. Chromosomal aberrations were more frequent in women (36 cases) than in men (20 cases). Prenatal cytogenetic analyses were carried out in 14 subsequent pregnancies for carrier couples with balanced translocation. The fetal karyotypes showed that 5 cases (35.7%) was normal, 8 (57.1%) were balanced translocation, and 1 (7.1%) was unbalanced translocations. And cytogenetic analyses were done on 15 subsequent chorionic villi samples of abortuses for carrier couples with balanced translocations. Fourteen of fifteen abortuses (93.3%) were abnormal karyotype. CONCLUSIONS: Although the incidence of chromosomal imbalance in the fetuses was relatively low in prenatal cytogenetic analysis, individuals with balanced translocations are predisposed to giving birth to malformed offsprings with chromosomal imbalance (partial trisomy or monosomy). Therefore we recommend preimplantation genetic diagnosis (PGD) for recurrent abortions with balanced translocation and preventing the birth of offspring with chromosomal abnormalities.

PURPOSE: The purpose of this study was to investigate the consumption behaviors of sugar-sweetened beverages and blood lipid profiles according to food-related lifestyles of adults in Incheon. METHODS: Subjects were recruited from 19 to 64 year old adults residing in Incheon who visited for the purpose of a health examination at D hospital. A total of 110 subjects consented to participate in this study and to allow their health examination records to be used at D hospital. Data were collected using self-administered questionnaires and anthropometric data, and blood lipid profiles were collected from health examination records. Statistical analysis was performed using the SPSS 20.0 program. RESULTS: In the factor analysis, food-related lifestyles were categorized into four factors: planned purchase seeking, taste seeking, well-being seeking, and convenience seeking. Using the K-average clustering method, food-related lifestyles of subjects were categorized into two groups: health and rationality-oriented group (HRG) and convenience purchase-oriented group (CPG). Average total scores of sugar-related nutrition knowledge in the HRG were significantly higher compared to the CPG, and average scores of consumption habits regarding sugar-containing foods in the HRG were significantly lower compared to the HRG. When subjects chose sugar-sweetened beverages, the CPG showed a significantly higher frequency of checking food labeling and considering nutrition compared to the CPG. Drinking frequency of carbonated beverages in the CPG was significantly higher compared to the HRG. CONCLUSION: There were significant differences in sugar-related nutrition knowledge and consumption habits of sugar-sweetened beverages between the two food-related lifestyle groups. These results could be useful for establishing guidelines for reducing consumption of sugar-sweetened beverages. In addition, it is necessary to continue sugar-related nutrition education by considering the food-related lifestyles of adults.
