PURPOSE: Lymphoma is considered when multiple, nonnecrotic lymph nodes are present in the superficial and deep lymphatic chains, especially if they are large and bilateral, on CT scan. It is reported that combined nodal and extranodal presentation of HD is uncommon. However, we found central low density in involved lymph node of NHL, and combined nodal and extranodal disease in HD, not infrequently. The purpose of this study is to ascertain whether our findings may be characteristics of NHL and HD. MATERIALS AND METHODS: CT findings with contrast enhancement were reviewed in 23 patients with untreated neck lymphoma:18 NHL and 5 HD. The followings were analyzed in each case: nodal or extranodal involvement; unilateral or bilateral involvement; presence or absence of central low density with peripheral enhancement in nodal lesion ;infiltration into adjacent structures. Nodal and extranodal lesions were confirmed by pathologic studies. RESULTS: Of 18 patients with NHL, nine cases had nodal disease and the rest had combined nodal and extranodal disease. Lymphadenopathy was bilateral in ten cases and unilateral in eight. Five cases with HD were composed of three combined nodal and extranodal diseases and two nodal diseases. Central low density of involved lymph node was shown in eight cases of 18 NHL and in one case of five HD. CONCLUSION: Central low density with peripheral enhancement was not uncommon in NHL, in contrast to HD. Hence, it is suggested that in case of nodal necrosis, NHL be also considered, besides tuberculous lymphadenitis and metastatic lymphadenopathy. It is not considered that nodal or extranodal disease, and unilateral or bilateral involvement are of high significance in differentiation of NHL from HD.

PURPOSE: Prostate volume has been poorly correlated with various parameters used to assess benign prostate hyperplasia (BPH), including symptom score, total prostate volume, peak flow rate and postvoid residual urine. The purpose of this study is to determine if measurement of the volume and the index of transition zone of the prostate correlated well with other clinical parameters in predicting the degree of obstruction. MATERIALS AND METHODS: 121 men with lower urinary tract symptoms were prospectively evaluated using international prostate symptom score, transrectal ultrasonography, and urodynamic investigation with pressure-flow studies for BPH. Bladder outlet obstruction was defined as the maximal detrusor pressure was greater than 40cmH2O at peak flow and peak flow rate was less than 10ml/sec. Patients were then divided into obstructive and non-obstructive groups. Correlations were evaluated among the total prostatic volume (TPV), transition zone volume (TZV), transition zone index (TZI=TZV/TPV) and other clinical and urodynamically obstructive parameters. RESULTS: Age, IPSS, peak flow rate and PVR were not significantly different between obstructive (n=69) and non-obstructive (n=52) groups. Among the transrectal sonographic parameters, TZV and TZI correlated better with urodynamically obstructive parameters such as detrusor pressure at peak flow rate (r=0.551, 0.544), Abrams Griffiths number (r=0.576, 0.506) and linear passive urethral resistance relation (r=0.560, 0.580) than with TPV. There were no correlations between clinical and volume parameters. All the volume parameters of the prostate were larger in obstructive than in non- obstructive group. CONCLUSIONS: In patients with BPH symptoms, TZV and TZI correlates better with urodynamically obstructive parameters than did the total prostate volume. TZV or TZI may serve as more useful method for evaluating obstruction.

The cause of essential hypertension is yet unknown, but in general is caused by interaction of hereditary factors, diet, obesity, lack of exercise and stress. The aging process influences various physiological mechanism related to regulation of blood pressure. So elderly hypertensives have a tendancy to consider the disease as a result of the physiological aging process. This attitude causes many complications, worsening of the disease and even early death because of inappropriate care. In order to improve self-management of elderly hypertensives in this study the researcher examined the effect of blood pressure regulation by an education program that improves self-care behavior, through increasing self-efficacy. The education program consisted of group education on hypertension and self-care strategies, and encouraging and reinforcing self-efficacy resources such as verbal persuation, performance accomplishment and vicarious experiences. A quasi-experimental pre-and post-test design was used. Thirty-two elderly hypertensives participated in the study. Eighteen in the education group and fourteen in the control group. The education program consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Data were analysed using SPSS for Windows(Version 8.0). The results were as follows. 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of self-care behavior between the experimental group and control group over three different times, and interaction by groups and over time. 3. There was significant difference in self-efficacy of experimental and control group, depending on the measuring period, but there was no difference between these groups on interaction by groups and over time. 4. There was positive correlation between self efficacy and self care behavior depending on the measuring period. There was negative correlation between diastolic blood pressure and self-care behavior on the posttest of the program, and between systolic blood pressure and self-care behavior on the follow-up test of the program. Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

PURPOSE: The purpose of this study was to identify the effects of abdominal breathing on state anxiety, stress and tocolytic dosage for pregnant women in preterm labor. METHODS: The participants were 60 pregnant women in preterm labor who were hospitalized from April to July, 2009. Thirty participants were assigned to the experimental group and 30 to the control group. None of them had any other complications except preterm labor. The modified Mason's breathing technique was used with the experimental group 3 times a day for 3 days. Data were collected using a self-report questionnaire and chart review, and analyzed with the SPSS 13.0 WIN program. RESULTS: "State anxiety of the experimental group will be lower than that of the control group" was supported. "Stress of the experimental group will be lower than that of the control group" was supported. "The Ritodrine dosage for the experimental group will be lower than that of the control group" was supported. "The Atosiban dosage for the experimental group will be lower than that of the control group" was supported. CONCLUSION: These results indicate that abdominal breathing is an effective nursing intervention for pregnant women in preterm labor.

PURPOSE: To improve self-management in elderly people with hypertension, the researcher examined the effects of an abdominal relaxed breathing exercises using biofeedback on blood pressure. These exercises regulate physical response to stress and lessen the activity of sympathetic nerves. METHOD: A single-experimental pre-and post-test design was used. Eight elderly people with hypertension participated in the study from April, 6 to June, 14, 2000. Biofeedback was done with soft ware by developed by J & J Company (1-410 form for abdominal respiration training). The abdominal relaxed breathing exercises are based on Mason's suggestion (1985) and were modified by Yu & Song(2001). This program consisted of 4 sessions once a week for four weeks. Data were analysed using SPSSPC+(10.0). RESULT: There was a significant decrease in systolic and diastolic blood pressure over three different times. There was a significant difference in the level of total stress response, overall health and quality of life but no significant difference in the level of emotional condition over three different times. CONCLUSION: The results of this study will contribute to the development of nursing strategies for the regulation of blood pressure in older people as the exercises are easy to learn and are a nonpharmacologic approach.

PURPOSE: E-cadherin(E-CD) is a family of Ca++-dependent intercellular adhesion molecules, plays essential roles in organogenesis and in the maintenance of normal structure and function. Decreased expression of E-CD correlates with tumor aggressiveness, advanced stage and metastasis. In renal cell carcinoma(RCC), however, this correlation is not well established and prevalence of negative expression of E-CD is higher than in other carcinomas. We focused our interest on E-CD expression in RCC and its clinicopathological implications. MATERIALS AND METHODS: Retrospectively, we reviewed 34 cases with RCC that were reclassified according to Mainz classification. Tumor stage, grade were determined according to the Robson method and Fuhrmann`s grading system. We detected E-CD expression in RCC by immunohistochemical staining and investigated the relationship between E-CD expression and clinicopathological features including prognosis. RESULTS: Thirty four cases of RCC were consisted of 21 cases(61%) of non-papillary clear cell type, 2 cases(6%) of chromophil type, 3 cases(9%) of spindle cell type and 8 cases(24%) of chromophobe type by Mainz classification. Especially, E-CD expression showed a strong positive reaction along the cell membranes in all 8 cases of chromophobe type. Our immunohistochemical study of E-CD expression in 34 RCC specimens showed 73% of positive expression and 27% of negative expression. Absence of E-CD expression was correlated with the high tumor stage and grade( stage & grade 3 or 4. p<0.05 in chi-squar test). All of metastatic cases showed a negative expression of E-CD. CONCLUSIONS: The differential expression of E-cadherin in renal cell carcinomas suggest that the tumor cell origin and differentiation. Especially, chromophobe cell type may have different biologic characteristics from other types of renal cell carcinoma. In this study, E-CD expression was seemed to be lost in RCC with a high stage and grade. In addition, preserved E-CD expression was associated with better prognosis than reduced E-CD expression.

OBJECTIVES: Periodic limb movement disorder (PLMD) has been debated with regard to its clinical significance and diagnostic criteria. The current diagnostic criterion for PLMD in adults has been changed from periodic limb movement index (PLMI) > 5/ hour to PLMI > 15/hour by the International Classification of Sleep Disorders (ICSD). In this study, we aimed to investigate the changes in polysomnographic sleep variables according to PLMI and to determine the relevance of the diagnostic criterion for PLMD. METHODS: Out of 4195 subjects who underwent standard polysomnography, we selected 666 subjects (370 males and 296 females, aged 47.1 ± 14.8) who were older than 17 years and were not diagnosed with primary insomnia, sleep apnea, narcolepsy, or REM sleep behavior disorder. Subjects were divided into three groups according to PLMI severity: group 1 (PLMI ≤ 5), group 2 (5 < PLMI ≤ 15), and group 3 (PLMI > 15). Demographic and polysomnographic sleep variables and Epworth sleepiness scale (ESS) were compared among the three groups. RESULTS: There were significant differences among the three groups in age and gender. Sleep efficiency (SE) and stage 3 sleep percentage in group 1 were significantly higher than those in groups 2 and 3. The wake after sleep onset (WASO) score in group 1 was significantly lower than those in groups 2 and 3. However, there were no significant differences in SE, stage 3 sleep percentage, or WASO between groups 2 and 3. Sleep latency (SL) in group 1 was significantly lower than that in group 3, but there was no difference in SL between group 2 and group 3. ESS score in group 1 was significantly higher than that in group 3, but there was no difference between group 2 and group 3. Partial correlation analysis adjusted by age showed that PLMI was significantly related to SE and WASO. CONCLUSION: This study suggests that PLMI influences polysomnographic sleep variables. In addition, we found the individuals who did not have PLMD but had PLMI > 5 were not different in polysomnographic sleep variables from the individuals who had PLMD according to the current criterion. These results raise questions about the relevance of the current diagnostic criterion of PLMD.

Transient Complete left bundle branch block (CLBBB) is defined as an intraventricular conduction defect that subsequently returns, if only temporarily, to normal conduction. CLBBB is usually permanent and associated with a structurally abnormal heart, especially the heart with artherosclerotic, hypertensive, or valvular disease. However, CLBBB may appear transiently and intermittently during anesthesia, although it is uncommon.It may be related to the changes in heart rate or blood pressure without any heart disease. Also, transient CLBBB may develop during anesthesia in the absence of associated tachycardia or hypertension. We report a case of transient CLBBB which developed without apparent associated hypertension or tachycardia during general endotracheal anesthesia.
