A statistical analysis of the diagnostic value for 244 aspiration biopsy cytology(ABC) among a total 1,043 cases from various sites was performed. ABC, using diagnostic terminology similar to that of a surgical pathology reports, was compared to the final tissue diagnosis. For the entire series, a sensitivity of 91.8%, a specificity of 99.3%, a positive predictive value of 98.9%, a negative predictive value of 94.8%, and an efficacy of the test of 96.3% were shown. There were 8 false negative and 1 false positive diagnosis. The diagnostic accuracy was 89.8%. Those results indicate that the ABC is a considerably highly accurate procedure that should be routinely employed.

The clinical and pathological features of a paraganglioma arising in the cauda equina is described and compared with previous reports. The right microscopic fetures were similar to those of paragangliomas from other sites, with a 'Zellballen' pattern of cells containing arzyrophil granules. Immunohistocytochemical stains for neurone specific enolase, S-100 protein, cytokeratin were positive, but stains for glial fibrillary acidic protein were negative. Electron microscopy showed densely staining membrane-bound granules, cilia like structures and fibros bodies in the cytoplasm. The last two features only occur in paragangliomas from this site. The pathological findings suggest that paragangliomas in this site arise from pre-existing paraganglia, possibly of the visceral autonomic group.

Purpose:
This study was conducted to evaluate the effects of nurse-led interventions on quality of life, medication adherence, anxiety, and depression in kidney transplant recipients.
Methods:
A systematic literature review was conducted following Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Two researchers independently selected the final literature, and the quality assessment was performed using Cochrane’s Risk of Bias tool. Additionally, a meta-analysis was conducted using the statistical software RevMan 5.4 to estimate effect sizes.
Results:
Among the reviewed 2,264 papers, 8 final papers, including 6 from the literature search and 2 from manual searches, were included in the analysis. The total number of participants included in the analysis was 477. Nurse-led interventions were found to be effective in improving quality of life (d=1.05) and reducing anxiety (d=-0.98) and depression (d=-1.25). Due to the heterogeneity of the measurement tools, the effect size for medication adherence could not be calculated. Despite this, nurse-led interventions were shown to improve medication adherence. In the cases of anxiety and depression, longer intervention periods showed a more significant reduction trend.
Conclusion
The results of this study suggest that nurse-led interventions positively impact quality of life, medication adherence, anxiety, and depression in kidney transplant recipients. Therefore, it is important to recognize the crucial role of nurses and explore ways to provide continuous nursing interventions for kidney transplant recipients.

BACKGROUND: Asthmatic patients frequently suffer cold-weather-associated respiratory symptoms. The sensitivity, specificity, accuracy and diagnostic value of isocapnic hyperventilation of cold air(IHCA) using a multistep method was investigated in patients suspected to have asthma. METHOD: One hundred and 29 adult patients who had an IHCA performed between july 1999 and December 2000, had an methacholine bronchoprovocation test because of a clinical suspicion of asthma. RESULTS: According to strict criteria, 50 were defined as asthmatics and 79 as symptomatic nonashmatics. There were no differences in age, sex and smoking state between the asthmatic and symptomatic nonasthmatic groups. There was a significant decrease in the percentage reduction in the forced expiratory volume in 1 second(FEV1) after the IHCA between the asthmatics(-10.0±6.8%) and the symptomatic nonasthmatics(-2.3±2.5%). The factors associated with a reactivity to IHCA were FEV1/FVC, FEF25-75/FVC and FEV1(% of predicted). The accuracy was highest using a 7% fall in FEV1; the sensitivity was 76% and the specificity 96%. CONCLUSION: IHCA is a specific, although not a sensitive, test for diagnosing asthma in adult patients. Furthermore, the diagnostic cut-off value of the different methods of IHCA need to be determined.

BACKGROUND: Increasing coronary perfusion pressure with phenylephrine is important treatment strategies for right ventricular dysfunction caused by pulmonary hypertension. We compared the effects of phenylephrine on systemic and pulmonary hemondynamics in patients with and without pulmonary hypertension. METHODS: Twenty patients undergoing a valvular replacement were divided into two groups according to pulmonary artery pressure (PAP): control group (mean PAP < 25 mmHg, n = 9) or pulmonary hypertension group (mean PAP > 25 mmHg, n = 11). When systolic blood pressure decreased below 100 mmHg after the induction of anesthesia, phenylephrine was infused to raise systolic blood pressure up to 30% and 50% over baseline. Hemodynamic variables were measured at each time. RESULTS: Phenylephrine failed to raise systolic blood pressure up to 50% above baseline in more than half of the patients with pulmonary hypertension in contrast to successful increases in all patients without pulmonary hypertension. However, the ratio of PAP to systolic blood pressure was significantly reduced in patients whose systolic blood pressure was successfully increased up to 50% over baseline in the pulmonary hypertension group whereas the PAP concomitantly increased as systolic blood pressure was increased in the control group. CONCLUSIONS: Phenylephrine couldn't increase systolic blood pressure in some patients with pulmonary hypertension unlike in control group and it seemed to occur more often in patients with greater the ratio of PAP to systolic blood pressure. The baseline systemic vascular resistance index was high and cardiacoutput was low in the pulmonary hypertension group and these conditions seemed to restrict the effect of phenylephrine.

Almost all advanced glomerular diseases have glomerular sclerotic changes to varying degrees whatever causes their primary glomerular disease are. Pathogenesis of these sclerosis has been thought of as the hyperfiltration in the primary glomerulosclerosis due to development of glomerular hypertension in each insulted glomeruli. This background gave the theoretical bases for antihypertensive therapies for supporting chronic renal insufficient patients. Angiotensin converting enzyme (ACE) inhibitor, one of the antihypertensive drugs, has received attention recently for its effectiveness. The aims of this study determined the effects and mechanism of the ACE inhibitor, enalapril, on the glomerulosclerosis in FGS/NgaKist mice, which was an animal model of chronic renal failure by generating spontaneously heavy proteinuria and progressive glomerulosclerosis. Five-week-old FGS/NgaKist mice (n=38) were assigned to four groups. Group 1a (n=6) and group 2a (n=8) fed with a vehicle, were sacrificed at the end of 10 weeks and 15 weeks, respectively. Group 1b (n=12) and 2b (n=12) received enalapril (100 mg/L) in drinking water for 5 weeks and 10 weeks from 6th week of age respectively, and were sacrified on the same day as the control groups. Doses of enanapril were maintained to 2 mg/kg/day by measuring the amount of water consumption. In enalapril groups 1b and 2b, systemic blood pressure (74.7 14.0 mm Hg, 74.3 15.9 mmHg) were significantly lower than control group 2a (116.1 4.6 mmHg, P<0.001). Similarly, degree of proteinuria lowered in enalapril group 2b versus control group 2a (0% and 50.0%, P<0.001). Glomerulosclerosis percentage significantly decreased (P<0.001) (group 1b and 2b; 1.9 6.5, 5.6 7.0 vs control 1a and 2a; 32.8 15.5, 31.4 13.8). Glomerulosclerosis score also decreased (P<0.001) (group 1b and 2b; 0.02 0.08 vs control 1a and 2a; 0.48 0.12, 0.30 0.14). The immunofluorescent staining of enalapril groups showed negative for mesangial deposition of IgG, IgA, IgM, and C3 which were positive in control groups. Immunohistochemical staining with TGF-beta1 was negative in enalapril groups and sclerotic glomeruli both enalapril groups and control groups. These results support that the ACE inhibitor has a renoprotective effect on glomerulosclerosis not only by decreasing the blood pressure but also by suppressing the immune deposits on glomeruli.
