Abstract
BACKGROUND Atrial tachycardia (AT) and atrial fibrillation (AF) coexist in 30% of congenital heart disease (CHD) patients. Successful atrial tachycardia catheter ablation (ATCA) might prevent AF. Data on new-onset AF after ATCA in CHD is scarce. OBJECTIVES This study aimed to evaluate the incidence of new-onset AF after ATCA and to assess clinical characteristics associated with new-onset AF after ATCA in CHD. METHODS CHD patients referred for ATCA to 3 European centers were included. New occurrence of AF was defined as electrocardiographic documentation of AF after any ATCA procedure in patients without history of AF. RESULTS In 277 CHD patients (median age 37 years [Q1, Q3: 23, 49 years], 58% men, 59 [21%] simple, 111 [40%] moderate, and 107 [39%] complex CHD), AF occurred in 25 patients (9%) a median of 8 months (Q1, Q3: 4, 27 months) after ATCA. New-onset AF was persistent in the majority of the patients (17 of 25 [63%]). Patients with new-onset AF were older (44 years [Q1, Q3: 29, 55 years] vs 36 years [Q1, Q3: 23, 49 years]; P = 0.009) and more frequently had simple CHD (13 of 25 [52%] vs 46 of 252 [18%], respectively; P < 0.0001). Acute ATCA success rates were similar in patients with and without AF (52% vs 48%; P = 0.429). Simple CHD was an independent predictor of new-onset AF during follow-up. CONCLUSIONS In our large cohort of patients with congenital heart disease, new-onset AF after ablation for AT occurred in only 9% of the patients. AF occurred without AT recurrence and was persistent in the majority of patients.

Abstract
Background:
This study aimed to describe the current practice and results of genetic evaluation in Dutch children with dilated cardiomyopathy and to evaluate genotype-phenotype correlations that may guide prognosis.
Methods:
We performed a multicenter observational study in children diagnosed with dilated cardiomyopathy, from 2010 to 2017.
Results:
One hundred forty-four children were included. Initial diagnostic categories were idiopathic dilated cardiomyopathy in 67 children (47%), myocarditis in 23 (16%), neuromuscular in 7 (5%), familial in 18 (13%), inborn error of metabolism in 4 (3%), malformation syndrome in 2 (1%), and “other” in 23 (16%). Median follow-up time was 2.1 years [IQR 1.0–4.3]. Hundred-seven patients (74%) underwent genetic testing. We found a likely pathogenic or pathogenic variant in 38 children (36%), most often in
MYH7
(n = 8). In 1 patient initially diagnosed with myocarditis, a pathogenic
LMNA
variant was found. During the study, 39 patients (27%) reached study endpoint (SE: all-cause death or heart transplantation). Patients with a likely pathogenic or pathogenic variant were more likely to reach SE compared with those without (hazard ratio 2.8; 95% CI 1.3–5.8,
P
= 0.007), while transplant-free survival was significantly lower (
P
= 0.006). Clinical characteristics at diagnosis did not differ between the 2 groups.
Conclusions:
Genetic testing is a valuable tool for predicting prognosis in children with dilated cardiomyopathy, with carriers of a likely pathogenic or pathogenic variant having a worse prognosis overall. Genetic testing should be incorporated in clinical work-up of all children with dilated cardiomyopathy regardless of presumed disease pathogenesis.

Abstract
BACKGROUND Approximately 25% of the patients with a history of Kawasaki disease (KD) develop coronary artery pathology if left untreated, with coronary artery aneurysms (CAA) as an early hallmark. Depending on the severity of CAAs, these patients are at risk of myocardial ischemia, infarction and sudden death. In order to reduce cardiac complications it is crucial to accurately identify patients with coronary artery pathology by an integrated cardiovascular program, tailored to the severity of the existing coronary artery pathology. METHODS The development of this practical workflow for the cardiovascular assessment of KD patients involve expert opinions of pediatric cardiologists, infectious disease specialists and radiology experts with clinical experience in a tertiary KD reference center of more than 1000 KD patients. Literature was analyzed and an overview of the currently most used guidelines is given. CONCLUSIONS We present a patient-specific step-by-step, integrated cardiovascular follow-up approach based on expert opinion of a multidisciplinary panel with expertise in KD.

Abstract
INTRODUCTION Neurodevelopmental delay is more common in children born with congenital heart defects (CHD), even with optimal perinatal and peri-operative care. It is hypothesized that fetuses with CHD are prone to neurological impairment in utero due to their cardiac defect, possibly leading to delayed cortical development. METHODS Cerebral cortical maturation was assessed with advanced neurosonographic examinations every 4 weeks in fetuses with CHD and compared to control fetuses. Five different primary fissures and four areas were scored (ranging 0-5) by blinded examiners using a cortical maturation scheme. RESULTS Cortical staging was assessed in 574 ultrasound examinations in 85 CHD fetuses and 61 controls. Small differences in grading were seen in Sylvian and cingulate fissures. (Sylvian fissure: -0.12 grade, 95% CI (-0.23; -0.01) p = 0.05, cingulate fissure: -0.24 grade, 95% CI (-0.38; -0.10) p = <0.001. Other cortical areas showed normal maturation as compared to control fetuses. CONCLUSION Small differences were seen in three of the nine analyzed cortical areas in CHD fetuses, in contrast to previous reports on progressive third-trimester delay. The clinical implications of the small differences however, remain unknown.

Abstract
Aims We aimed to determine whether in children with dilated cardiomyopathy repeated measurement of known risk factors for death or heart transplantation (HTx) during disease progression can identify children at the highest risk for adverse outcome. Methods and results Of 137 children we included in a prospective cohort, 36 (26%) reached the study endpoint (SE: all‐cause death or HTx), 15 (11%) died at a median of 0.09 years [inter‐quartile range (IQR) 0.03–0.7] after diagnosis, and 21 (15%) underwent HTx at a median of 2.9 years [IQR 0.8–6.1] after diagnosis. Median follow‐up was 2.1 years [IQR 0.8–4.3]. Twenty‐three children recovered at a median of 0.6 years [IQR 0.5–1.4] after diagnosis, and 78 children had ongoing disease at the end of the study. Children who reached the SE could be distinguished from those who did not, based on the temporal evolution of four risk factors: stunting of length growth (−0.42 vs. −0.02 length Z‐score per year, P < 0.001), less decrease in N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) (−0.26 vs. −1.06 2log pg/mL/year, P < 0.01), no decrease in left ventricular internal diastolic dimension (LVIDd; 0.24 vs. −0.60 Boston Z‐score per year, P < 0.01), and increase in New York University Pediatric Heart Failure Index (NYU PHFI; 0.49 vs. −1.16 per year, P < 0.001). When we compared children who reached the SE with those with ongoing disease (leaving out the children who recovered), we found similar results, although the effects were smaller. In univariate analysis, NT‐proBNP, length Z‐score, LVIDd Z‐score, global longitudinal strain (%), NYU PHFI, and age >6 years at presentation (all P < 0.001) were predictive of adverse outcome. In multivariate analysis, NT‐proBNP appeared the only independent predictor for adverse outcome, a two‐fold higher NT‐proBNP was associated with a 2.8 times higher risk of the SE (hazard ratio 2.78, 95% confidence interval 1.81–3.94, P < 0.001). Conclusions The evolution over time of NT‐proBNP, LVIDd, length growth, and NYU PHFI identified a subgroup of children with dilated cardiomyopathy at high risk for adverse outcome. In this sample, with a limited number of endpoints, NT‐proBNP was the strongest independent predictor for adverse outcome.

Abstract
Objectives Presumably, changes in fetal circulation contribute to the delay in maturation of the cortex in fetuses with congenital heart defect (CHD). The aim of the current study is to analyze fetal brain development based on hemodynamic differences, using novel brain‐age prediction software. Methods We have performed detailed neurosonography, including acquiring 3D volumes, prospectively in cases with isolated CHD from 20 weeks onwards. An algorithm that assesses the degree of fetal brain‐age automatically was used to compare CHD cases to controls. We stratified CHD cases according to flow and oxygenation profiles by lesion physiology and performed subgroup analyses. Results A total of 616 ultrasound volumes of 162 CHD cases and 75 controls were analyzed. Significant differences in maturation of the cortex were observed in cases with normal blood flow toward the brain (−3.8 days, 95%CI [−5.5; −2.0], P = <.001) and low (−4.0 days, 95% CI [−6.7; −1.2] P = <.05; hypoplastic left heart syndrome[HLHS]) and mixed (−4.4 days, 95%CI [−6.4; −2.5] p = <.001) oxygen saturation in the ascending aorta (TGA) and in cardiac mixing (eg, Fallot) cases. Conclusion The current study shows significant delay in brain‐age in TGA and Fallot cases as compared to control cases. However, the small differences found in this study questions the clinical relevance.

Abstract
BACKGROUND Congenital heart disease is present in 44-56% of fetuses with Down syndrome (DS). There are, however, signs that hearts in DS without apparent structural heart defects also differ from those in the normal population. We aimed to compare the atrioventricular (AV) septum and valves in 3 groups: DS without AV septal defect (DS no-AVSD), DS with AVSD (DS AVSD) and control hearts. METHODS The ventricular septum, membranous septum and AV valves were examined and measured in histological sections of 15 DS no-AVSD, 8 DS AVSD and 34 control hearts. In addition, the ventricular septum length was measured on ultrasound images of fetal (6 DS AVSD, 9 controls) and infant (10 DS no-AVSD, 10 DS AVSD, 10 controls) hearts. RESULTS The membranous septum was 3 times larger in DS no-AVSD fetuses compared to control fetuses, and valve dysplasia was frequently (64%) observed. The ventricular septum was shorter in patients with DS both with and without AVSD, as compared to the control group. CONCLUSION DS no-AVSD hearts are not normal as they have a larger membranous septum, shorter ventricular septum and dysplasia of the AV valves as compared to control hearts.

Abstract
OBJECTIVES The Senning or Mustard procedure combined with the arterial switch operation (ASO) (± VSD and no left ventricular (LV) outflow tract obstruction) or the Rastelli operation (VSD and LV outflow tract obstruction) has become the preferred strategy over conventional repair as it is thought to prevent long-term dysfunction of the right ventricle (RV). More recently, hemi-Mustard rerouting of blood from the inferior vena cava to the RV in combination with bidirectional cavopulmonary anastomosis (BCPA) has been adopted by some centres for potential benefits over the classic atrial switch procedure. The aim of this study was to analyse our experience with hemi-Mustard and BCPA as part of an anatomical repair of congenitally corrected transposition of the great arteries (CCTGA) in selected patients. METHODS Between 2004 and 2011, eight patients underwent hemi-Mustard/BCPA with the Rastelli operation (n = 6) or ASO (n = 2). The median age was 2.9 (range: 1.2-9.1) years. Positional anomalies were present in 75% of the patients. Both patients with ASO had dysplastic and insufficient tricuspid valves. In the Rastelli group, four patients had previously received shunts followed by BCPA in one patient. In the ASO group, both patients underwent pulmonary artery banding initially. RESULTS There was one in-hospital death and no late mortality. Two patients received a pacemaker. One patient from the Rastelli group required conduit change 6 years later. At the mean follow-up of 4.5 years, six and one patients are in NYHA classes I and II, respectively; six patients showed good biventricular function, while one had LV dysfunction. Systemic venous obstruction and sinus node dysfunction were not observed, and BCPA was functioning well in all patients. CONCLUSIONS Hemi-Mustard/BCPA is useful in anatomical repair of CCTGA in selected patients. When compared with the classic atrial switch operation, it is technically easier which makes it especially helpful in atrio-apical discordance; it unloads an RV with limited size or function, and avoids complications related to the upper limb of the classic atrial switch procedure. Mid-term results of this approach are favourable. Further follow-up is needed to prove long-term benefits.

Abstract
Umbilical venous catheters (UVCs) are commonly used in the management of severely ill neonates. Several life-threatening complications have been described, including catheter-related infections, myocardial perforation, pericardial effusion and cardiac arrhythmias. This report describe two neonates with cardiac arrhythmias due to umbilical venous catheterisation. One neonate had a supraventricular tachycardia requiring treatment with intravenous adenosine administration. Another neonate had an atrial flutter and was managed successfully with synchronised cardioversion. The primary cause of cardiac arrhythmias after umbilical venous catheterisation is inappropriate position of the UVC within the heart and the first step to treat them should be to pull back or even remove the catheter. Cardiac arrhythmia is a rare but potentially severe complication of umbilical venous catheterisation in neonates.

Abstract
There are very few published reports of the transcatheter closure of perimembranous ventricular septal defects (PMVSDs) using the Amplatzer PMVSD occluder with encouraging initial results. This report presents initial and 1-year results from 54 patients with PMVSDs who underwent transcatheter closure at 5 different institutions with the Amplatzer PMVSD occluder. Sixty-five patients with PMVSDs were enrolled at 5 European centers. Eleven of the 65 patients did not fulfill the patient selection criteria at the initial echocardiographic evaluation or at cardiac catheterization. As a result, a total of 54 patients underwent attempted transcatheter closure using the Amplatzer PMVSD occluder. The median age of the patients was 5.1+/-3.6 years (range 0.3 to 13), and the median weight 18.5+/-10.3 kg (range 5 to 45). Devices were permanently implanted in 49 of 54 patients. Complete occlusion of the communication at 1-year follow-up was observed in 46 of 49 patients (94%). Main early procedural complications included (1) device embolization (2 patients), (2) severe bradycardia with hemodynamic compromise (2 patients), and (3) Mobitz II (2:1) heart block (1 patient). Late procedural complications included complete heart block (1 patient). No other complications were observed during follow-up. In conclusion, the Amplatzer PMVSD occluder is promising device that can be used for transcatheter closure in selected patients with PMVSDs. Further studies and long-term follow-up are required before this technique enters routine clinical practice.

Abstract
BACKGROUND Chronic twin-to-twin transfusion syndrome (TTTS) is a complication of monochorionic twin gestations and is associated with high perinatal mortality and increased neurological, cardiovascular and renal morbidity. OBJECTIVE To report the risk of severe persistent pulmonary hypertension of the newborn (PPHN) in TTTS and discuss the possible association between severe PPHN and TTTS. METHODS All cases of monochorionic twins with severe PPHN at birth admitted to our nursery between June 2002 and July 2006 were reviewed retrospectively. We compared the incidence of severe PPHN in monochorionic twins with and without TTTS. Severe PPHN was diagnosed according to clinical and ultrasound criteria when an infant with a structurally normal heart had (1) severe hypoxemia and (2) evidence of a right-to-left shunt on persistent ductus arteriosus or foramen ovale, requiring treatment with inhaled nitric oxide (iNO). RESULTS In a consecutive series of 73 twin pregnancies with TTTS, 4 of the 135 live-born twins (3%) were affected by severe PPHN. All reacted promptly to treatment with iNO. The incidence of severe PPHN in monochorionic twins without TTTS was 0% (0/161). CONCLUSION In view of the severe clinical course in PPHN and need for adequate and prompt treatment with iNO, perinatologists should be aware of the increased risk of severe PPHN in TTTS.

Abstract
Myocardial perfusion imaging with technetium-99m-labelled methoxyisobutyl isonitrile single photon emission computed tomography (99mTc-MIBI SPECT) has proven to be an important clinical procedure in assessing the severity of myocardial ischaemia. The uptake and clearance of 99mTc-MIBI by the myocardium is affected by cell viability and membrane integrity. Consequently, infectious diseases, such as myocarditis, may also affect myocardial perfusion by inducing local inflammation and necrosis. We compared 99mTc-MIBI myocardial perfusion imaging with other heart monitoring methods in order to assess its value in the diagnosis of children with Coxsackie viral myocarditis. We examined 46 patients (age, 3-12 years) with Coxsackie viral myocarditis using 99mTc-MIBI myocardial perfusion imaging and compared the perfusion data with myocardial enzymes, electrocardiographic findings and echocardiography. Regions of hypoperfusion were found in all 46 patients. Seventeen patients (37%) showed two or more areas of diminished perfusion. Myocardial hypoperfusion was mild-to-moderate (<30%) in 33 (72%) patients and severe (>30%) in 13 (28%) patients. Characteristic creatine-kinase isoenzyme (CK-MB) increases, ST-T segment changes and diminished heart function were significantly correlated with reduced myocardial perfusion (all comparisons P<0.05). The results of this study suggest that the presence of myocardial uptake of 99mTc-MIBI may be a marker of myocardial inflammation and necrosis. All 46 patients with Coxsackie viral myocarditis showed a certain degree of reduced perfusion. When the perfusion findings were compared with other parameters, it was shown that myocardial enzyme levels, ST-T segment changes and left ventricular function correlated well with the 99mTc-MIBI-established perfusion defect severity. 99mTc-MIBI SPECT imaging is therefore helpful in providing additional diagnostic information in patients with Coxsackie viral myocarditis.

Abstract
UNLABELLED Major coronary artery anomalies are extremely rare in childhood. We wanted to assess the historical and diagnostic features and the therapeutic options of three distinct types of coronary artery anomalies: abnormal origin of the left coronary artery from the pulmonary artery (ALCAPA), coronary fistula and coronary stenosis. In a retrospective study, 33 children with these types of coronary artery disease were identified, 15 with ALCAPA, 12 with fistula and six with coronary stenosis. History, physical examination, ECG, X-ray, echocardiography, angiography, therapy and outcome were reviewed. ALCAPA showed distinct typical echocardiographic characteristics. Coronary artery fistula could be identified by a typical murmur and echocardiographic evidence of coronary dilatations. Coronary stenosis should be suspected by the clinical picture in a specific context. CONCLUSION rare coronary artery anomalies can be accurately diagnosed in childhood. Timely therapy yields good prognosis.

Abstract
We have developed an entirely sequence-based method that identifies and integrates relevant features that can be used to assign proteins of unknown function to functional classes, and enzyme categories for enzymes. We show that strategies for the elucidation of protein function may benefit from a number of functional attributes that are more directly related to the linear sequence of amino acids, and hence easier to predict, than protein structure. These attributes include features associated with post-translational modifications and protein sorting, but also much simpler aspects such as the length, isoelectric point and composition of the polypeptide chain.

Abstract
OBJECTIVE The cytomegalovirus (CMV) antigenemia consists of the detection of CMV pp65 in the nucleus of polymorphonuclear granulocytes (PMN), but it is unclear where and how PMN pick up virus particles or proteins. In an in vitro model for CMV antigenemia we investigated the mechanism of pp65 uptake by PMN that results in its expression in the nucleus. METHODS A series of inhibitors of different mechanisms was used to study the uptake of pp65 by PMN during coculture with CMV-infected endothelial cells and we performed a morphological analysis by light and transmission electron microscopy. RESULTS Nocodazole and cytochalasin B inhibited uptake of pp65 by PMN with 59.4 +/- 14.1 and 73.3 +/- 12.7%, respectively. The presence of anti-CMV hyperimmune globulin or lactoferrin during coculture reduced the number of pp65-positive PMN with 45.8 +/- 7.0 or 40.6 +/- 3.2%. Furthermore, a small number of the pp65-positive PMN obtained after coculture had fused to large cells with multilobed nuclei. PMN were observed that enclosed viral particles as well as free viral particles containing PMN in the cytoplasm. CONCLUSION Fusion of viral particles with PMN and phagocytosis are both involved in the uptake of pp65.

Ultrastructural morphology (transmission electron microscopy) and localisation of cisplatin-induced platinum (Pt)-DNA adducts (immunoelectron microscopy) were analysed in the human small cell lung cancer cell line GLC(4) and its 40-fold in vitro acquired cisplatin-resistant subline GLC(4)-CDDP, which is characterised by, among other things, a decreased DNA platination. Immunolabelling of Pt-DNA adducts was performed with the polyclonal antibody GPt, known to detect the main Pt-containing intrastrand and interstrand DNA adducts. Morphological analysis of GLC(4) and GLC(4)-CDDP at the ultrastructural level showed cells with a high nucleus/cytoplasm ratio with the majority of nuclei containing one or more nucleoli. GLC(4)-CDDP showed, in contrast to GLC(4), an extensive Golgi apparatus and an increased number of mitochondria. DNA platination was detectable in both GLC(4) and GLC(4)-CDDP. Immunoelectron microscopy showed Pt-DNA adducts primarily in the nucleus, preferentially at loci with high-density chromatin (e.g. heterochromatin, pars granulosa around nucleoli, condensed DNA in proliferating and apoptotic cells), and in mitochondria. The level of detectable Pt-DNA adducts was cell cycle status-dependent. In both cell lines, Pt-DNA adduct levels increased from non-dividing interphase cells to dividing cells and were highest in cells undergoing apoptosis. Overall localisation of Pt-DNA adducts was comparable in GLC(4) and GLC(4)-CDDP cells.

Abstract
The glial cell line-derived neurotrophic factor (GDNF)-family of neurotrophic factors consisted until recently of three members, GDNF, neurturin, and persephin. We describe here the cloning of a new GDNF-family member, neublastin (NBN), identical to artemin (ART), recently published (Baloh et al., 1998). Addition of NBN/ART to cultures of fetal mesencephalic dopamine (DA) neurons increased the number of surviving tyrosine hydroxylase (TH)-immunoreactive neurons by approximately 70%, similar to the maximal effect obtained with GDNF. To investigate the neuroprotective effects in vivo, lentiviral vectors carrying the cDNA for NBN/ART or GDNF were injected into the striatum and ventral midbrain. Three weeks after an intrastriatal 6-hydroxydopamine lesion only about 20% of the nigral DA neurons were left in the control group, while 80-90% of the DA neurons remained in the NBN/ART and GDNF treatment groups, and the striatal TH-immunoreactive innervation was partly spared. We conclude that NBN/ART, similarly to GDNF, is a potent neuroprotective factor for the nigrostriatal DA neurons in vivo.

Abstract
Protein phosphorylation at serine, threonine or tyrosine residues affects a multitude of cellular signaling processes. How is specificity in substrate recognition and phosphorylation by protein kinases achieved? Here, we present an artificial neural network method that predicts phosphorylation sites in independent sequences with a sensitivity in the range from 69 % to 96 %. As an example, we predict novel phosphorylation sites in the p300/CBP protein that may regulate interaction with transcription factors and histone acetyltransferase activity. In addition, serine and threonine residues in p300/CBP that can be modified by O-linked glycosylation with N-acetylglucosamine are identified. Glycosylation may prevent phosphorylation at these sites, a mechanism named yin-yang regulation. The prediction server is available on the Internet at http://www.cbs.dtu.dk/services/NetPhos/or via e-mail to NetPhos@cbs. dtu.dk.

Abstract
The site and sequence specificity of protein kinases, as well as the role of the secondary structure and surface accessibility of the phosphorylation sites on substrate proteins, was statistically analyzed. The experimental data were collected from the literature and are available on the World Wide Web at http://www.cbs.dtu.dk/databases/PhosphoBase/. The set of data involved 1008 phosphorylatable sites in 406 proteins, which were phosphorylated by 58 protein kinases. It was found that there exists almost absolute Ser/Thr or Tyr specificity, with rare exceptions. The sequence specificity determinants were less strict and were located between positions -4 and +4 relative to the phosphorylation site. Secondary structure and surface accessibility predictions revealed that most of the phosphorylation sites were located on the surface of the target proteins.

Abstract
Extended delineation of water molecules, monitored using Rfree values, afforded considerable improvement in quality of electron-density maps for structure determination of mammalian class I and E. coli class II aldolases. Augmented solvent definition results in an additional decrease in Rfree values of 3-4% and is reflected in significantly enhanced electron-density envelopes enabling tracing of amino-acid sequences through regions of otherwise discontinuous or weak electron density.

Abstract
PhosphoBase is a database of experimentally verified phosphorylation sites. Version 1.0 contains 156 entries and 398 experimentally determined phosphorylation sites. Entries are compiled and revised from the literature and from major protein sequence databases such as SwissProt and PIR. The entries provide information about the phosphoprotein and the exact position of its phosphorylation sites. Furthermore, part of the entries contain information about kinetic data obtained from enzyme assays on specific peptides. To illustrate the use of data extracted from PhosphoBase we present a sequence logo displaying the overall conservation of positions around serines phosphorylated by protein kinase A (PKA). PhosphoBase is available on the WWW at http://www.cbs.dtu.dk/databases/PhosphoBase/

Abstract
The structure of fructose 1,6-bisphosphate aldolase shows three distinct modes of product binding that are correlated to the disposition of the C-terminal region and depicts a possible trajectory for product exchange. The structure also indicates binding preference for monobasic triose phosphates.

Abstract
Picornaviral proteinases are responsible for maturation cleavages of the viral polyprotein, but also catalyze the degradation of cellular targets. Using graphical visualization techniques and neural network algorithms, we have investigated the sequence specificity of the two proteinases 2Apro and 3Cpro. The cleavage of VP0 (giving rise to VP2 and VP4), which is carried out by a so-far unknown proteinase, was also examined. In combination with a novel surface exposure prediction algorithm, our neural network approach successfully distinguishes known cleavage sites from noncleavage sites and yields a more consistent definition of features common to these sites. The method is able to predict experimentally determined cleavage sites in cellular proteins. We present a list of mammalian and other proteins that are predicted to be possible targets for the viral proteinases. Whether these proteins are indeed cleaved awaits experimental verification. Additionally, we report several errors detected in the protein databases. A computer server for prediction of cleavage sites by picornaviral proteinases is publicly available at the e-mail address NetPicoRNA@cbs.dtu.dk or via WWW at http:@www.cbs.dtu.dk/services/NetPicoRNA/.

Abstract
The presence of cytomegalic inclusion cells in the peripheral blood of patients with an active cytomegalovirus infection has recently been demonstrated. Immunologic staining showed that these cells were of endothelial origin. Study of circulating cytomegalic cells by transmission electron microscopy showed the cells to be productively infected with cytomegalovirus. Viral capsids were present in the nucleus and virus particles and dense bodies were found in the cytoplasm. The results indicate that these circulating cytomegalic cells could disseminate cytomegalovirus throughout the body. In addition, the finding of a cluster of cytomegalic cells in the peripheral blood linked together by zonula adherens type cell junctions is further evidence that these cells are of endothelial origin and suggests that the endothelial damage may be extensive.

Abstract
A population of B cells with characteristics of chronic lymphocytic leukaemia was found in the peripheral blood of four patients who presented with cutaneous infiltration of atypical CD4+ T cells with cerebriform nuclei. The B cells had a low density of immunoglobulin on their surface membrane, expressed CD5-positivity, and showed monoclonality based on the restriction to either kappa or lambda light chains. In one patient with tumourous pleiomorphic CD4+CD30- T-cell lymphoma of the skin, it was the first manifestation of a concomitant B-cell non-Hodgkin's lymphoma of low-grade malignancy. In three other patients with reactive atypical T-cell erythroderma, there was no evidence for the coexistence of a B-cell malignancy. The number of CD5+ B cells decreased in two erythroderma patients with clinical remission of the cutaneous lesions. It is speculated that the presence of a monoclonal B cell population in patients with T-cell disorders of the skin is due either to a reactive process possibly conferring some protective effect, or a response to an unknown stimulus produced by the T cells.
