Abstract
BACKGROUND As previously reported there is evidence for a reduction in right to left shunt (RLS) in stroke patients with patent foramen ovale (PFO). This occurs predominantly in patients with cryptogenic stroke (CS). We therefore analysed factors associated with a shunt reduction on follow-up in stroke patients suffering of CS. METHODS On index event PFO and RLS were proven by transesophageal echocardiography and contrast-enhanced transcranial Doppler-sonography (ce-TCD). Silent PE was proved by ventilation perfusion scintigraphy (V/Q) within the stroke work-up on index event; all scans were re-evaluated in a blinded manner by two experts. The RLS was re-assessed on follow-up by ce-TCD. A reduction in shunt volume was defined as a difference of ≥20 microembolic signals (MES) or the lack of evidence of RLS on follow-up. For subsequent analyses patients with CS were considered; parameters such as deep vein thrombosis (DVT) and silent pulmonary embolism (PE) were analysed. RESULTS In 39 PFO patients suffering of a CS the RLS was re-assessed on follow-up. In all patients (n = 39) with CS a V/Q was performed; the median age was 40 years, 24 (61.5%) patients were female. In 27 patients a reduction in RLS was evident. Silent PE was evident in 18/39 patients (46.2%). Factors such as atrial septum aneurysm, DVT or even silent PE were not associated with RLS dynamics. A greater time delay from index event to follow-up assessment was associated with a decrease in shunt volume (median 12 vs. 6 months, p = 0.013). CONCLUSIONS In patients with CS a reduction in RLS is not associated with the presence of a venous embolic event such as DVT or silent PE. A greater time delay between the initial and the follow-up investigation increases the likelihood for the detection of a reduction in RLS.

Abstract
Background Cerebral venous thrombosis (CVT) is a disease with a wide spectrum of symptoms and severity. In this study we analysed the predictive value of clinical signs and symptoms and the contribution of D-dimer measurements for diagnosis. Methods We evaluated consecutive patients admitted with suspected CVT receiving non-invasive imaging. Symptoms and symptom combination as well as D-dimer levels were evaluated regarding their diagnostic value. Results 239 patients were included in this study, 170 (71%) were females. In 39 patients (16%) a CVT was found. For identifying a CVT patients underwent either a venous CT-angiography or MR-angiography or both. No combination of symptoms either alone or together with the D-dimer measurements had a sensitivity and positive predictive value as well as negative predictive value and specificity high enough to serve as red flag. D-dimer testing produced rates of 9% false positive and of 24% false negative results. For D-dimer values a Receiver Operating Characteristic curve (ROC) and the area under the curve (AUC = 0.921; CI: 0.864 - 0.977) were calculated. An increase of sensitivity above 0.9 results in a relevant decrease in specificity; a sensitivity of 0.9 matches a specificity value of 0.9. This corresponds to a D-dimer cut-off level of 0.16 μg/ml. Conclusion Imaging as performed by venous CT-angiography or MR-angiography has a 1 to 2 in 10 chance to detect CVT when typical symptoms are present. D-dimer measurements are of limited clinical value because of false positive and negative results.

Abstract
BACKGROUND AND PURPOSE Deep vein thrombosis and pulmonary embolism (PE) prove venous embolic activity and enforce the suspicion of paradoxical embolism in patients with stroke with patent foramen ovale. Because it has implications in secondary prevention, we investigated the frequency of silent PE in such a cohort of patients. METHODS Patients with cryptogenic stroke or transient ischemic attack and patent foramen ovale who underwent a ventilation perfusion scintigraphy were identified from a stroke registry. Blinded from clinical data, ventilation perfusion scintigraphy scans were re-evaluated independently by 2 experts. Patients showing at least a subsegmental defect were considered as having silent PE. Factors potentially associated with PE were analyzed. RESULTS The evaluation included 151 patients. Median age was 55.2 years and 59.9% were male. In 56 (37%) patients, silent PE was found; a deep vein thrombosis was evident in 11 (7%) patients. Atrial septal aneurysm was identified in 39 patients and hypermobile atrial septum in 37 patients. Atrial septal aneurysm and hypermobile atrial septum were independently associated with PE. In females, intake of oral contraceptives showed certain association with PE (6 of 25 versus 3 of 40; P=0.07). CONCLUSIONS Silent PE frequently occurs in patients with cryptogenic stroke and patent foramen ovale, particularly when atrial septal aneurysm or hypermobile atrial septum are present.

Abstract
BACKGROUND In patients with patent foramen ovale (PFO) there is evidence supporting the hypothesis of a change in right-to-left shunt (RLS) over time. Proven, this could have implications for the care of patients with PFO and a history of stroke. The following study addressed this hypothesis in a cohort of patients with stroke and PFO. METHODS The RLS volume assessed during hospitalisation for stroke (index event/T0) was compared with the RLS volume on follow-up (T1) (median time between T0 and T1 was 10 months). In 102 patients with a history of stroke and PFO the RLS volume was re-assessed on follow-up using contrast-enhanced transcranial Doppler/duplex (ce-TCD) ultrasound. A change in RLS volume was defined as a difference of ≥20 microembolic signals (MES) or no evidence of RLS during ce-TCD ultrasound on follow-up. RESULTS There was evidence of a marked reduction in RLS volume in 31/102 patients; in 14/31 patients a PFO was no longer detectable. An index event classified as cryptogenic stroke (P < 0.001; OD = 39.2, 95% confidence interval 6.0 to 258.2) and the time interval to the follow-up visit (P = 0.03) were independently associated with a change in RLS volume over time. CONCLUSIONS RLS volume across a PFO decreases over time, especially in patients with cryptogenic stroke. These may determine the development of new strategies for the management in the secondary stroke prevention.

Abstract
We investigated the expression of intercellular adhesion molecules ICAM-1 and ICAM-3 on peripheral blood mononuclear cells in a subgroup of 34 patients with relapsing-remitting multiple sclerosis who were treated orally with the chemokine receptor 1 antagonist BX 471 in a 16-week, randomised, double-blind, placebo-controlled phase II study. ICAM-1 and ICAM-3 expression was measured by flow cytometry at different time points during and after therapy and compared using multivariate analysis of variance and non-parametric Mann Whitney test. ICAM-3 expression on CD14 + peripheral blood mononuclear cells was increased in the verum group under therapy, but did not differ significantly between the verum and placebo groups. Most likely, this trend represents a small epiphenomenon only mediated by receptor cross-talk and feedback mechanisms.

Abstract
The impact of defined urogenital inflammations on standard ejaculate parameters is still a matter of controversial debate. Basic spermiogram parameters has been analysed in patients with inflammatory and noninflammatory chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS-NIH IIIA/IIIB) with regard to indicators of inflammation in prostatic secretions and/or the ejaculate. A total of 112 consecutive patients symptomatic for chronic pelvic pain were included in the study. All of them underwent a 'four glass-test' including leukocyte determination in expressed prostatic secretions followed by ejaculate analysis according to WHO. The analysis included pH, volume, total sperm count, sperm density, motility, morphology (Shorr stain), vitality (eosin stain), and counting of peroxidase positive leukocytes (PPL). Patients were first subgrouped according to elevated leukocyte counts in prostatic secretions, and then according to the number of PPL in semen. Leukocytes neither in the prostatic secretions nor in the ejaculate were associated with reduced standard semen parameters. Our data supports previous results that elevated leukocyte counts in prostatic secretions and in ejaculate, as indicators of inflammation have no negative impact on total sperm count, sperm density, motility, morphology, and sperm vitality in patients with CP/CPPS.

Abstract
The new prostatitis classification proposes the inclusion of seminal leukocytes in the diagnosis of inflammatory chronic pelvic pain syndrome (CPPS). The present study has been performed to clarify the role of seminal leukocytes and inflammatory seminal plasma parameters in order to contribute to the differential diagnosis between inflammatory (category IIIA) and non-inflammatory (category IIIB) CPPS. A total of 112 consecutive symptomatic patients (mean age 37.3 years; range 21-64) attending our prostatitis outpatient clinic were investigated. Men with evidence for bacterial infection were excluded by prior standardized lower urinary tract localization studies. Men were categorized into inflammatory and non-inflammatory CPPS according to the leukocyte analysis in expressed prostatic secretions (EPS) and urine after prostatic massage (VB 3). Ejaculate analysis was performed after lower urinary tract localization studies. Inflammatory markers included peroxidase positive leukocytes (PPL) and PMN-elastase. Receiver operating characteristic curves were constructed to analyze cutpoints provided that the differences were significant. Increased leukocyte counts in EPS/VB 3 were found in 64 men, while in 48 this was not the case. No differences could be detected in relation to patients' age ( P>0.05). In men with category IIIA prostatitis, PPL and elastase in the seminal fluid were significantly increased ( P<0.001). For PPL and elastase, a cutpoint of 0.113 x 10(6)/ml and 280 ng/ml, respectively, were suggested. Increased PPL (>0.113 x 10(6)/ml) and elastase (>280 ng/ml) in the seminal fluid indicate inflammatory disease provided that the ejaculate analysis is performed on the same day after lower urinary tract localization studies.

Abstract
OBJECTIVE To study a possible relationship between expression of the transcription factor glucocorticoid receptor (GR), which mediates antiinflammatory effects, and the transcription factor p50, which mediates proinflammatory effects, in peripheral blood mononuclear cells (PBMC) of patients with rheumatoid arthritis (RA). METHODS Expression analysis of GR and nuclear factor-kB subunit p50 in PBMC was performed by semiquantitative immunoblotting. RESULTS GR and p50 expression in PBMC were significantly increased in patients with RA who had never received corticosteroids. In contrast, GR density is decreased in glucocorticoid treated RA patients. In addition, a dependency between increased GR expression and increased p50 expression was found. CONCLUSION The pathogenesis of RA is not reflected in diminished GR expression but rather in an increased expression level of GR, as well as increased p50 expression in PBMC. Corticosteroids as the major therapeutic drugs result in a reduction of these increased GR and p50 expression levels.

Abstract
OBJECTIVE The aim of the study was to evaluate the secretory dysfunction of the male accessory glands in men with inflammatory versus non-inflammatory chronic pelvic pain syndrome (CPPS). METHODS One hundred and twelve consecutive patients symptomatic for chronic pelvic pain were included into the study. All underwent a combined granulocyte analysis in expressed prostatic secretions (EPS) and a four-glass-test followed by ejaculate analysis. Patients were subgrouped according to elevated granulocyte counts in prostatic secretions, leukocytes in semen, or any of both. The content/total enzyme activity of the secretory seminal plasma parameters gamma-glutamyl-transferase (gamma-GT), fructose, and alpha-glucosidase representing the secretory capacity of the prostate gland, the seminal vesicles, and the epididymes, respectively, were investigated. RESULTS The only significant findings were a reduced total enzyme activity of gamma-GT in men stratified according to elevated granulocyte counts in prostatic secretions (p=0.022; cutpoint 9.85U per ejaculate; sensitivity 61.1%, specificity 58.8%, AUC 0.6347) and in men with any inflammatory sign (p=0.033; cutpoint 9.9U per ejaculate, sensitivity 63%, specificity 58.33%, AUC 0.6404). CONCLUSIONS Secretory damage of the prostate gland in men with inflammatory CPPS is demonstrable provided that increased granulocytes in prostatic secretions are part of the diagnostic criteria. However, because of the low sensitivity and specificity of gamma-GT it cannot be recommended as diagnostic tool to detect inflammatory disease on the basis of reduced secretory capacity.

Abstract
Mitochondrial gene mutations have been recognized to be associated with diabetes mellitus. The incidence of diabetes mellitus in patients with other mitochondrial diseases, such as chronic progressive external ophthalmoplegia (CPEO), seems to be several times higher than in the normal population. The aim of the present investigation was to study insulin sensitivity index (SI), insulin secretion (AIR(Glucose)), and glucose effectiveness (Sg) in patients with CPEO. Six unrelated patients with CPEO and 6 matched-pair, unrelated, healthy control subjects underwent a modified intravenous glucose tolerance test (IVGTT) (Bergman's minimal model). Three patients demonstrated an impaired glucose tolerance (IGT), 1 patient already had diabetes mellitus. No significant difference between patients and controls could be demonstrated for SI, AIR(Glucose), or fasting insulin. However, there was a significant difference for glucose effectiveness Sg (P =.016) indicating an impaired glucose effectiveness in the CPEO patients. The diabetic patient showed insulin resistance, low AIR(Glucose), and low Sg. We conclude that there is a high incidence of IGT and diabetes mellitus in patients with CPEO. Impaired glucose effectiveness seems to play a major role in early pathogenesis. Overt diabetes in CPEO seems to be a combination of insulin resistance, an insulin secretion defect, and impaired glucose effectiveness.

Abstract
Lymphocytopenia and depression of natural killer cells have been observed in patients with adrenoleukodystrophy (ALD) treated with glycerol trioleate and glycerol trierucate ('Lorenzo's oil'). To investigate possible alterations of cellular immunoreactivity, we measured lymphocyte proliferation in response to mitogens (PHA, Con A, PWM, OKT3) in 27 patients on treatment and in 14 patients without treatment. In patients on treatment, lymphocyte proliferation in response to the mitogens PHA and Con A was significantly higher than in patients without treatment. Lymphocyte proliferation in patients without treatment was comparable to that of normal control lymphocytes. Additionally, we found increased concentrations of erucic acid, C22:1, in lymphocytes from patients with treatment. The enhanced proliferation of lymphocytes in response to mitogens is an indication of increased reactivity of cellular immunity to unspecific immunological stimuli. Long-term side-effects on cellular immunoreactivity have to be considered in ALD patients treated with Lorenzo's oil.

GOAL Comparison of fast MRI, echocardiography (Echo), and ventricular angiography (Cath) in the assessment of left ventricular global function. METHODS Fast MRI in short axis plane, biplane Cath, and 2D Echo were performed in 62 patients [35 coronary artery diseases, 16 acquired valvular diseases (VD), 9 dilated cardiomyopathies (DCM), 1 congenital heart disease and 1 heart transplantation]. Enddiastolic (EDV), endsystolic (ESV), stroke volumes (SV), cardiac output (CO), and ejection fraction (EF) were compared in MRI and Cath. EF was visually estimated in 2D Echo by an experienced observer. RESULTS In comparison to MRI, Cath overestimated EF by 8.4%, and Echo underestimated EF by 5.6%. The limits of agreement between MRI and Cath in EF were +/- 23.8%, between MRI and Echo +/- 18%, and between Echo and Cath +/- 19.4%. Significant differences were found between Cath and MRI in EDV, SV, and CO, but not for ESV. The best agreement in EF was found in the group with DCM, the worst in the group with VD. CONCLUSION Important systemic and random errors were found in the comparison of MRI, Echo, and Cath. For therapy decision and follow-up, the methods should not be exchanged unscrupulously.

Abstract
Our goal was to establish right ventricular (RV) volume and ejection fraction (EF) values in normal volunteers with fast magnetic resonance (MR) imaging using a breath-hold technique, to assess the frequency and severity of RVEF abnormality in cardiac patients and to compare RV with left ventricular (LV) data. We performed simultaneously derived RV and LV fast cine measurements in 52 normals and 325 patients with coronary artery disease (CAD), acquired valvular disease (VD), cardiomyopathy (CM), or congenital heart disease (CHD). RVEF was reduced in 31% (102) of all patients, in 50% dilated CM, 39% CHD, 34% CAD, and 22% acquired VD patients. Solitary abnormally low RVEF was found in only 15/325 (5%) of all patients, whereas combined with LVEF deterioration in 87/172 (51%) patients. RVEF reduction was mild in 64%, moderate in 25%, and severe in 11%. Although RVEF correlated significantly (r = 0.55, P < 0.001) with LVEF, the predictive value of LVEF for RVEF was low. We conclude that RV volumes can be routinely assessed with fast MRI and should be performed in addition to LV evaluation in CHD, in right-sided VD, and in all patients with an abnormal LVEF.J. Magn.

Abstract
PURPOSE Evaluation and comparison of localized and global left and right ventricular ejection and filling with fast cine MR imaging in the breath-hold technique. MATERIALS AND METHODS 10 healthy volunteers were examined with a 1.5 Tesla unit and phased-array-coil using a segmented FLASH-2D sequence in breath-hold technique. Peak ejection and peak filling rates [PER, PFR end-diastolic volume (EDV)/s)]. time to PER and PFR [TPER, TPFR ms] and time of end-systole [TSYS in % RR-interval] of all slices (complete-slice-evaluation) were evaluated and compared to three left ventricular and one right ventricular slices (reduced three-slice-evaluation). RESULTS There were significant regional left ventricular differences of PER (p = 0.002) and PFR (p = 0.007), but not of TPER and TPFR. Ejection and filling indices of the left ventricular middle slice were closest to the overall evaluation of all sections. In the left-/right-side comparison the right ventricular PFR was higher than the left ventricular (5.1 and 4.2 EDV/s) and the right ventricular TPFR was earlier than the left (92.2 and 123.5 ms). CONCLUSIONS With fast cine techniques, regional and global left and right ventricular ejection and filling indices can be evaluated in addition to the global heart volume indices. The three-slice-evaluation represents a comprehensive, clear and time-saving method for daily routine.

Abstract
BACKGROUND Glare disability and appearance of halos may be side-effects of cataract, but were also described in patients with multifocal IOLs. The aim of this study was to compare glare sensitivity and halo size in phakic and pseudophakic eyes. PATIENTS AND METHODS Contrast sensitivity without and with glare and halos around a light source were measured by means of a new computerized test in patients with cataract, monofocal IOLs, multizonal progressive and diffractive multifocal IOLs as well as in a younger control group of subjects with clear lenses. Glare acuity was measured at three different luminance settings. RESULTS Patients with cataract showed the most important reduction in contrast sensitivity, noticed significantly larger halos and were more impaired in glare acuity than patients with monofocal or multizonal progressive IOLs. There was no significant difference in any criteria between these two pseudophakic groups. Subjects with a clear cristalline lens had statistically significant better results compared with all other groups. CONCLUSION An increase in glare sensitivity and the appearance of halos are more important in patients with even minor cataracts than in any pseudophakic population. As a consequence of this study, night driving ability should be carefully examined in any pseudophakic patient, but also in any subject with even beginning cataract.

Abstract
In the CBA/J (H-2k) x DBA/2J (H-2d) murine model, the protective value of pooled murine immunoglobulin i.p. was compared with that of serum taken 7 days after termination of CBA/J (H-2k) x BALB/c (H-2d) pregnancy. A control group of CBA/J females received treatment with autologous virgin serum. CBA/J females at 7 weeks of age were injected 3 days before mating with DBA/2J males and 3 days after sighting of the vaginal plug. An effect of treatment can be shown following IgG therapy (P less than 0.05). The highest rate of viable fetuses was documented in the immunoglobulin-treated females, while the rate of viable offspring did not differ in the two serum-treated animal groups.

Abstract
The effect of positive end-expiratory pressure (PEEP) ventilation on the pancreas was studied in 22 anesthetized minipigs. Five pigs were treated with intermittent positive pressure ventilation (IPPV) for 21 h (Group I) and six pigs were treated with a PEEP of 15 cm H2O for 21 h (Group II). We next explored the influence of PEEP ventilation while stimulating the pancreas with Ceruletide, a synthetic cholecystokinin (CCK) analog, at 2.3 micrograms/kg per h.i.v. for 3 h. Ventilation with IPPV for 4 h (n = 5, group III) was compared with PEEP of 15 cm H2O for 4 h (n = 6, group IV). Changes in serum-lipase were observed in all groups. The average lipase level rose from 12.6 U/l to 67 U/l group I and from 15.1 U/l to 129.2 U/l in group II (P = 0.025 for group I vs group II). In group IV (PEEP and Ceruletide), the mean lipase level rose about six times more than in group III (IPPV and Ceruletide). The difference was significant (P less than 0.00005). By three-factor ANOVA analysis, effects due to the drug (P less than 0.000006) and to PEEP (P less than 0.038) as well as a threefold interaction could be demonstrated, i.e., using Ceruletide a greater PEEP effect on lipase than without the drug (P less than 0.023) took place. There were no significant histological changes of the pancreas in groups I and III. In group II (21 h PEEP), vacuolization of acinar cells was evident; on the ultrastructural level, indication was given that these vacuoles derived both from the Golgi apparatus and from fusion of individual zymogen granules. In group IV (PEEP and Ceruletide), the focal appearance of fatty-tissue necrosis and acinar cells as well as hemorrhage of the gland was observed. We conclude that PEEP ventilation impairs the function of the pancreas and produces even more deleterious effects when the gland is stimulated. These effects should be considered when PEEP is used in clinical practice in the treatment of acute pancreatitis.

Abstract
Oxygen consumption (VO2) must be known to calculate the hemodynamic parameters by Fick's principle. Often VO2 is not measured directly but calculated by nomograms. An open-system method was used for measuring oxygen consumption continuously in 140 healthy infants and children and 152 with congenital heart disease. The patients with heart disease were divided in three groups: I - with large left-to-right shunt (more than 40%), II - with a small left-to-right shunt, and III - without left-to-right shunt. In group I a significantly higher oxygen consumption was measured. There was also a difference in relation of indexed oxygen consumption to age between group I and all the other children. In a second part we compared two methods for determination of indexed oxygen consumption (VO2) in infants and children: measurement using an open system method estimation by using formulas. In healthy infants estimation showed higher values; but no difference was found in healthy children or those without significant left-to-right shunt. In children with congenital heart disease and large left-to-right shunt measured VO2 was significantly higher than the estimated values. No correlation was found in infants with large left-to-right shunt. But in these cases the exact calculation of the hemodynamic parameters would be of great importance. The results indicate that measurement rather than estimation of VO2 is necessary for calculation of hemodynamic parameters.

Abstract
Elastase, a specific inflammatory parameter of polymorphonuclear (PMN) granulocytes, was quantified with a sensitive enzyme immunoassay in the ejaculates of 188 patients consulting the andrological outpatient service. Correlations of the elastase concentrations to other parameters used up to now for the diagnosis of silent male genital tract inflammation were statistically evaluated by the CHI2-test. A correlation was found neither to the percentage of morphologically intact spermatozoa in the differential spermiocytogram and the total number of spermatozoa nor to the pH-value and viscosity of the ejaculate. However, release of elastase into the ejaculates was clearly associated with the occurrence of bacteria in native and stained smears or with the numbers of round cells present. Moreover, leukocyte counts in stained smears as well as an inflammation coefficient were highly significantly correlated to elastase concentrations. Obviously, quantification of granulocyte elastase in seminal plasma enables a rapid diagnosis of silent male genital tract inflammation, since even a single determination gives a reliable criterion and sequential determinations may allow the control of the course of the disease during therapy.

Abstract
The occlusion time ("haemostasis time" - HT) of a thin, short cannula inserted into the cubital vein, was compared with the skin bleeding times of the Duke and Ivy/template techniques. 25 male and 25 female volunteers without a history of bleeding were divided into 5 equally large age groups ranging from 10 to over 50 years of age. They exhibited a range of 46 s-6 min 38 s (95% tolerance interval), while the Duke and Ivy/template bleeding times, which were simultaneously determined, corresponded to values given by other authors. HT is different from the skin bleeding times in that endothelium is replaced by a standard foreign surface which allows better standardization of the method. Similar results were obtained with HT compared to the skin bleeding times. These and a similar, non-significant heparin response with all three techniques suggest that HT is not more influenced by clotting factors than the Duke and Ivy/template bleeding times and, indeed, may be regarded as a bleeding time modification. HT, like both of the skin bleeding times, reflected lowered platelet counts and is even more sensitive in this respect. As tested in a group of 20 male and 20 female volunteers, HT showed a significant prolongation two hours after ingestion of 1 g aspirin. While male individuals exhibited longer bleeding times than females with the Ivy/template technique (sex-related difference p = 0.01), no male to female differences were found both with HT and the Duke bleeding time. HT is easy to perform, inexpensive, leaves no scars and is safe even for the patient with severe bleeding. Moreover, compared to the skin bleeding times, it permits a differential evaluation of vessel wall and tissue effects.
