Abstract
The Type III secretion system (TTSS) facilitates the export of effector proteins from pathogenic and symbiotic Gram-negative bacteria into the cytosol of eukaryotic host cells. The current functional and evolutionary knowledge on the molecular recognition of TTSS substrates and computational models of the secretion signal are discussed in this review.

Abstract
Protozoa play host for many intracellular bacteria and are important for the adaptation of pathogenic bacteria to eukaryotic cells. We analyzed the genome sequence of "Candidatus Amoebophilus asiaticus," an obligate intracellular amoeba symbiont belonging to the Bacteroidetes. The genome has a size of 1.89 Mbp, encodes 1,557 proteins, and shows massive proliferation of IS elements (24% of all genes), although the genome seems to be evolutionarily relatively stable. The genome does not encode pathways for de novo biosynthesis of cofactors, nucleotides, and almost all amino acids. "Ca. Amoebophilus asiaticus" encodes a variety of proteins with predicted importance for host cell interaction; in particular, an arsenal of proteins with eukaryotic domains, including ankyrin-, TPR/SEL1-, and leucine-rich repeats, which is hitherto unmatched among prokaryotes, is remarkable. Unexpectedly, 26 proteins that can interfere with the host ubiquitin system were identified in the genome. These proteins include F- and U-box domain proteins and two ubiquitin-specific proteases of the CA clan C19 family, representing the first prokaryotic members of this protein family. Consequently, interference with the host ubiquitin system is an important host cell interaction mechanism of "Ca. Amoebophilus asiaticus". More generally, we show that the eukaryotic domains identified in "Ca. Amoebophilus asiaticus" are also significantly enriched in the genomes of other amoeba-associated bacteria (including chlamydiae, Legionella pneumophila, Rickettsia bellii, Francisella tularensis, and Mycobacterium avium). This indicates that phylogenetically and ecologically diverse bacteria which thrive inside amoebae exploit common mechanisms for interaction with their hosts, and it provides further evidence for the role of amoebae as training grounds for bacterial pathogens of humans.

Abstract
The prediction of protein function as well as the reconstruction of evolutionary genesis employing sequence comparison at large is still the most powerful tool in sequence analysis. Due to the exponential growth of the number of known protein sequences and the subsequent quadratic growth of the similarity matrix, the computation of the Similarity Matrix of Proteins (SIMAP) becomes a computational intensive task. The SIMAP database provides a comprehensive and up-to-date pre-calculation of the protein sequence similarity matrix, sequence-based features and sequence clusters. As of September 2009, SIMAP covers 48 million proteins and more than 23 million non-redundant sequences. Novel features of SIMAP include the expansion of the sequence space by including databases such as ENSEMBL as well as the integration of metagenomes based on their consistent processing and annotation. Furthermore, protein function predictions by Blast2GO are pre-calculated for all sequences in SIMAP and the data access and query functions have been improved. SIMAP assists biologists to query the up-to-date sequence space systematically and facilitates large-scale downstream projects in computational biology. Access to SIMAP is freely provided through the web portal for individuals (http://mips.gsf.de/simap/) and for programmatic access through DAS (http://webclu.bio.wzw.tum.de/das/) and Web-Service (http://mips.gsf.de/webservices/services/SimapService2.0?wsdl).

Abstract
Who may treat early Barrett's carcinoma of the oesophagus? The incidence of adenocarcinoma of the oesophagus developing within Barrett's mucosa has substantially risen in the past few years. Furthermore, treatment of preneoplastic lesions or early carcinoma is controversial. From an endoscopist's point of view high-grade intraepithelial neoplasia (HG-IEN) should be resected endoscopically rather than destroyed endoscopically while early Barrett's carcinoma should undergo endoscopic staging resection. Surgical resection is rarely necessary because lymph node metastases are rare and there is some morbidity and mortality associated with the procedure. However, surgeons argue that complete surgical resection is required because no imaging technique reveals the exact extent of the lesion and, ultimately, the degree of infiltration can only be determined within the resected specimen. Also, only surgical procedures may remove all potentially involved regional lymph nodes. Furthermore, only within surgical resections we can eliminate all pre-existing Barrett's mucosa easily while endoscopic clearance of Barrett's mucosa is difficult and requires multiple sessions. The Merendino-Siewert procedure may be an option with very low morbidity and mortality. It is worthy of note that new endoscopic resection procedures have not been studied in a controlled fashion against conventional surgical procedures. Therefore, patients with HG-IEN or early Barrett's carcinoma of the esophagus should be recruited into controlled studies and be treated in specialised high-volume centres.

Abstract
In future, the profile of gastroenterology in Germany - as in other countries - will change. New achievements such as capsule endoscopy, aero-scopes and advanced CT and MRI technology and others will become alternatives to conventional endoscopy. Additional emphasis in clinical and outpatient gastroenterology is shifted towards gastrointestinal oncology, dietetics, nutrition and metabolism and in the clinical setting onto infectious diseases, endocrinology/diabetology, intensive care medicine, emergency service and geriatric medicine. The German Confederation of Gastroenterology (BVGD) initiated two Germany-wide surveys on the current diagnostic and therapeutic spectrum in hospitals and out-patient facilities to achieve a base for future discussions regarding the development of gastroenterology. The number of gastroenterologists working in hospitals and in out-patient facilities has been analysed as well as the number of examinations passed successfully during the last few years in the speciality "gastroenterology". The results of this survey offer a valid basis for continuing discussions as to how gastroenterology should develop in Germany.

Abstract
4508 Background: Octreotide is currently used for the control of symptoms in patients with gastroenteropancreatic neuroendocrine tumors (NETs). However, the ability of long-acting somatostatin analogues to control the growth of well-differentiated metastatic NETs is a matter of debate. The analysis of the first randomized, double-blind, placebo-controlled, multicenter, phase IIIb study of octreotide LAR in patients with metastatic NETs of the midgut is presented. Methods: Treatment-naïve patients with histologically confirmed locally inoperable or metastasized well-differentiated NETs and a Karnofsky index >60 were randomized to receive either octreotide LAR 30 mg/month (mo) or placebo for 18 mos, or until tumor progression or death. The primary endpoint was median time to tumor progression. Secondary endpoints included objective tumor response rate (WHO criteria), measured every 3 mos, as well as symptom control and overall survival. This was a planned interim analysis using the Lan-DeMets error spending approach. Results: Eighty-five patients (n=43 octreotide LAR; n=42 placebo) have been enrolled to date and data from 67 patients with tumor progressions and 16 deaths (n=7 octreotide LAR; n=9 placebo) are included here. Median time to tumor progression in the octreotide LAR and placebo groups were 14.3 mos and 6 mos, respectively (HR: 0.34; 95% CI: 0.20–0.59; P=0.000072). After 6 mos of treatment, stable disease was seen in 67% and 37.2% of patients treated with octreotide LAR and placebo, respectively. Due to the low number of observed deaths, median survival time could not be estimated. Conclusions: Octreotide LAR significantly lengthens median time to tumor progression compared with placebo in patients with metastatic NETs of the midgut. Patients treated with octreotide LAR had a 66% risk reduction of tumor progression compared with patients receiving placebo. Octreotide LAR demonstrates substantial tumor control and shows a more favorable antiproliferative response than placebo as two-thirds of patients treated with octreotide LAR achieved stable disease at 6 mos.

Abstract
Hepatitis E virus (HEV) is the major cause of several outbreaks of waterborne hepatitis in tropical and subtropical countries and of sporadic cases of viral hepatitis in endemic and industrialised countries. Generally, HEV causes an acute self-limiting hepatitis. The clinical course is characterised by transient viraemia and transaminasaemia followed by a full hepatic recovery. Recent studies describe prolonged and chronic HEV infections in some immunosuppressed patients after solid organ transplantation. Here, an indigenous acute limited hepatitis E in a patient with Philadelphia chromosome-positive acute lymphoblastic leukaemia prior to allogeneic stem cell transplantation is reported. Fourteen weeks after stem cell transplantation, reappearance of HEV viraemia was observed, with increasing viral load and modestly elevated serum transaminases. Sequence analysis of the viral RNAs revealed a reactivation of endogenous HEV genotype 3, indicating viral persistence after recovery from acute hepatitis E.

Abstract
UNLABELLED Heparin-induced thrombocytopenia (HIT II) in childhood is rare. Suspected HIT II requires immediate diagnostic and therapeutic measures in order to avoid potentially life threatening complications. Heparin must be stopped immediately. We report on a 6-year old boy who required cardiac surgery due to tetralogy of Fallot. To our knowledge he had been exposed to heparin for the first time during cardiac catheterization on the day before surgery. Preoperatively, platelet count was normal. Postoperatively (3 days after heparin exposure), he developed pulmonary and renal failure and required inotropic cardiac support and dialysis. He also developed progressive (severe) thrombocytopenia under heparin therapy on day 2-3 postoperatively. The dialysis filter required daily exchanges due to clotting despite increasing heparin doses. The first ELISA for HIT on postop day 4 was negative. 3 days later a repeated test was positive. Von Willebrand factor antigen and D-dimers were markedly increased. The patient was immediately switched to lepirudin and subsequently stabilized slowly. No major systemic thrombosis occurred. After lepirudin treatment for 6 weeks the patient was fully recovered and HIT II-testing was negative again. CONCLUSION In children with progressive thrombocytopenia in the setting of heparin exposure and signs of major or micro thrombosis HIT II must be ruled out. Even if a first early test turns out negative repeated testing should be performed. Lepirudin anticoagulation is effective and should be monitored correctly. Platelet transfusion should be avoided in HITII.

Abstract
Social interaction is profoundly affected in the behavioural form of frontotemporal dementia (bvFTD) yet there are few means of objectively assessing this. Diagnosis of bvFTD is based on informant report, however a number of individuals with a clinical profile consistent with the disease have no imaging abnormality and seem to remain stable, with doubt about the presence of underlying neurodegenerative pathology. We aimed to quantify aspects of the behavioural disorder and link it to the underlying level of atrophy in socially relevant brain regions. We tested individuals with either bvFTD (N = 26) or Alzheimer's disease (N = 9) and 16 controls using The Awareness of Social Inference Test (TASIT) to assess their ability to identify emotion and sarcasm in video vignettes. A subset of bvFTD patients (N = 21) and controls (N = 12) were scanned using MRI within 6 months of assessment. There was marked impairment in the ability of bvFTD patients whose scans showed abnormalities to recognize sarcastic, but not sincere statements. Their capacity to interpret negative emotion was also impaired, and this appeared to be a major factor underlying the deficit in sarcasm recognition. Clinically diagnosed bvFTD patients whose scans were normal, Alzheimer's disease patients and controls had no difficulty in appreciating both types of statement. In a multivariate imaging analysis it was shown that the sarcasm (and emotion recognition) deficit was dependent on a circuit involving the lateral orbitofrontal cortex, insula, amygdala and temporal pole, particularly on the right. Performance on a more global test of cognitive function, the Addenbrooke's Cognitive Examination did not have a unique association with these regions. The TASIT is an objective test of social dysfunction in bvFTD which indexes the frontotemporal volume loss in bvFTD patients and provides an objective measure for separating behavioural patients who are likely to decline from those who may remain stable. These results provide additional evidence for the role of the orbitofrontal cortex and related structures in the processing of socially relevant signals, particularly those where negative emotion recognition is important.

Abstract
We present 60 patients with refractory (n=8) or relapsed (n=52) adult ALL who received allogeneic hematopoietic SCT (HSCT) with (n=41) or without (n=19) prior reinduction chemotherapy. In our center, omission of reinduction is recommended if a suitable donor is promptly available, tumor burden is moderate and disease features suggest a highly aggressive course. Overall survival (OS) of the whole cohort at 1, 2 and 5 years was 42, 33 and 28%, respectively. Leukemia-free survival at 1, 2 and 5 years was 37, 33 and 24%. Deaths were due to relapse (n=25), acute or chronic GVHD (n=7), infections (n=8) or toxicity (n=4). Interestingly, patients who did not receive reinduction before HSCT had better outcomes than patients who received reinduction with OS at 1, 2 and 5 years being 58 vs 34%, 47 vs 25% and 47 vs 18%, respectively (P=0.039). Importantly, even achievement of a second CR after reinduction was not associated with improved survival compared to patients directly proceeding to HSCT. We conclude that patients who undergo HSCT for refractory or relapsed ALL can achieve long-term survival. In selected patients, reinduction chemotherapy can be omitted if immediate HSCT is feasible.

Abstract
The web server probeCheck, freely accessible at http://www.microbial-ecology.net/probecheck, provides a pivotal forum for rapid specificity and coverage evaluations of probes and primers against selected databases of phylogenetic and functional marker genes. Currently, 24 widely used sequence collections including the Ribosomal Database Project (RDP) II, Greengenes, SILVA and the Functional Gene Pipeline/Repository can be queried. For this purpose, probeCheck integrates a new online version of the popular ARB probe match tool with free energy (ΔG) calculations for each perfectly matched and mismatched probe-target hybrid, allowing assessment of the theoretical binding stabilities of oligo-target and non-target hybrids. For each output sequence, the accession number, the GenBank taxonomy and a link to the respective entry at GenBank, EMBL and, if applicable, the query database are displayed. Filtering options allow customizing results on the output page. In addition, probeCheck is linked with probe match tools of RDP II and Greengenes, NCBI blast, the Oligonucleotide Properties Calculator, the two-state folding tool of the DINAMelt server and the rRNA-targeted probe database probeBase. Taken together, these features provide a multifunctional platform with maximal flexibility for the user in the choice of databases and options for the evaluation of published and newly developed probes and primers.

Abstract
As part of the International Multi-centre ADHD Genetics project we completed an affected sibling pair study of 142 narrowly defined Diagnostic and Statistical Manual of Mental Disorders, fourth edition combined type attention deficit hyperactivity disorder (ADHD) proband-sibling pairs. No linkage was observed on the most established ADHD-linked genomic regions of 5p and 17p. We found suggestive linkage signals on chromosomes 9 and 16, respectively, with the highest multipoint nonparametric linkage signal on chromosome 16q23 at 99 cM (log of the odds, LOD=3.1) overlapping data published from the previous UCLA (University of California, Los Angeles) (LOD>1, approximately 95 cM) and Dutch (LOD>1, approximately 100 cM) studies. The second highest peak in this study was on chromosome 9q22 at 90 cM (LOD=2.13); both the previous UCLA and German studies also found some evidence of linkage at almost the same location (UCLA LOD=1.45 at 93 cM; German LOD=0.68 at 100 cM). The overlap of these two main peaks with previous findings suggests that loci linked to ADHD may lie within these regions. Meta-analysis or reanalysis of the raw data of all the available ADHD linkage scan data may help to clarify whether these represent true linked loci.

Abstract
Exposure to cocaine in utero results in behavioral and neurodevelopmental abnormalities that persist into adulthood. Conventional MR imaging has generally failed to reveal the expected structural lesions to explain these clinical findings. We report a case of focal MR imaging signal-intensity changes in the substantia nigra, locus ceruleus, and other selected nerve tracts and nuclei in a child exposed prenatally to cocaine and other drugs. The patient also had dilated cardiomyopathy.

Abstract
Fusarium infections are associated with high mortality after allogeneic stem cell transplantation. We report on successful treatment of a disseminated cutaneous Fusarium proliferatum infection using liposomal amphotericin B and terbinafine. In vitro susceptibility tests of antifungal drugs suggest that terbinafine is a potent additional antifungal drug for disseminated cutaneous fusariosis.

Abstract
Protein sequences are the most important source of evolutionary and functional information for new proteins. In order to facilitate the computationally intensive tasks of sequence analysis, the Similarity Matrix of Proteins (SIMAP) database aims to provide a comprehensive and up-to-date dataset of the pre-calculated sequence similarity matrix and sequence-based features like InterPro domains for all proteins contained in the major public sequence databases. As of September 2007, SIMAP covers ∼17 million proteins and more than 6 million non-redundant sequences and provides a complete annotation based on InterPro 16. Novel features of SIMAP include a new, portlet-based web portal providing multiple, structured views on retrieved proteins and integration of protein clusters and a unique search method for similar domain architectures. Access to SIMAP is freely provided for academic use through the web portal for individuals at http://mips.gsf.de/simap/and through Web Services for programmatic access at http://mips.gsf.de/webservices/services/SimapService2.0?wsdl.

Abstract
Several observations suggest that caveolin-1 has an important role in control of cell proliferation and cancerogenesis. For instance, oxytocin provokes a proliferative response in the prostate tissue when the oxytocin receptor is localized mainly in caveolin-1-enriched domains and an anti-proliferative effect when the same receptor is not localized in caveolae. Moreover, oxytocin concentrations are elevated in prostate tissue of patients with benign prostatic hyperplasia (BPH). In this study the expression pattern of the molecules caveolin-1, oxytocin receptor, androgen receptor and p21 (cell cycle arrest indicator) was investigated in the prostate tissue of BPH patients and of young controls. We found that both caveolin-1 and oxytocin receptor expression is drastically increased with age in both smooth muscle and epithelium of the prostate. We also found a significantly increased co-localization of the oxytocin receptor with caveolin-1 in both the muscle and the epithelium, especially in BPH patients. Androgen receptor and p21 staining was found throughout the prostate but did not change significantly with age or in BPH patients. We conclude that oxytocin may have a proliferative effect on the prostate tissue through the caveolae-associated receptors and thus contribute to BPH. This process seems to be androgen receptor independent.

Abstract
MOTIVATION Sequence similarity searches are of great importance in bioinformatics. Exhaustive searches for homologous proteins in databases are computationally expensive and can be replaced by a database of pre-calculated homologies in many cases. Retrieving similarities from an incrementally updated database instead of repeatedly recalculating them should provide homologs much faster and frees computational resources for other purposes. RESULTS We have implemented SIMAP-a database containing the similarity space formed by almost all amino acid sequences from public databases and completely sequenced genomes. The database is capable of handling very large datasets and allows incremental updates. We have implemented a powerful backbone for similarity computation, which is based on FASTA heuristics. By providing WWW interfaces as well as web services, we make our data accessible to the worldwide community. We have also adapted procedures to detect putative orthologs as example applications. AVAILABILITY The SIMAP portal page providing links to SIMAP services is publicly available: http://mips.gsf.de/services/analysis/simap/.

Abstract
PURPOSE To compare the aortic compliance of the normal-sized aorta of adolescents with Marfan syndrome and healthy controls using MR measurements of the aortic distensibility and pulse wave velocity. MATERIALS AND METHODS Fourteen patients (median age: 15 years) and 11 healthy subjects (23 [12 - 32] years) were examined at 1.5 T. The MR protocol included 2D steady-state free precession (SSFP)-CINE MRI of the aortic distensibility and PC-MRI of the pulse wave velocity. All measurements were positioned perpendicular to the descending aorta at the level of the diaphragm for assessing the changes in the aortic cross-sectional areas and additionally above and below this plane for assessing the pulse wave velocity. In addition contrast-enhanced 3D-MR angiography was performed in adolescents with Marfan syndrome to exclude morphologic changes and to prove normal-sized aorta. RESULTS Compared with control subjects, adolescents with Marfan syndrome had significantly decreased distensibility and significantly increased pulse wave velocity (chi (2)-test, p = 0.0002) using an age-related non-linear regression analysis. The related aortic compliance was significantly decreased (chi (2)-test, p = 0.0002). There was a good correlation between the two methods (r = 0.86). A low intraobserver variability was found for both methods (< or = 2 %). CONCLUSIONS MRI allows detecting abnormal elastic aortic wall properties already in the normal-sized aorta of adolescents with Marfan syndrome. Monitoring of these properties could be relevant for evaluating disease onset and progression. MRI has the potential value of compliance measurements for the follow-up and to guide therapy indications.

Abstract
Hematopoietic cell transplantation (HCT) is an effective treatment for myelodysplasia (MDS) and secondary acute myeloid leukemia (sAML). In this study, outcome of 593 patients with MDS/sAML after autologous and allogeneic HCT from a matched unrelated donor (MUD) were compared. A total of 167 (28%) patients received HCT from MUD without prior chemotherapy (MUD-U). The rest received HCT in first complete remission (CR1) (Autologous (Auto-CR1), n=290 (49%), HCT from MUD (MUD-CR1), n=136 (23%)). Survival at 3 years was best in MUD-CR1 (50%) compared to Auto-CR1 (41%) and MUD-U (40%) (P=0.01). Similarly, disease-free survival was 44% for MUD-CR1 compared to Auto-CR1 (28%) and MUD-U (34%) (P=0.03). Treatment-related mortality was 17% in Auto-CR1 compared to MUD-CR1 (38%) and MUD-U (49%) (P<0.001). Relapse for Auto-CR1 was 62% compared to 24 and 30% for MUD-CR1 and MUD-U, respectively (P<0.001). Outcome was best for patients with low tumor burden transplanted 6-12 months after diagnosis. Factors influencing outcome at 3 years were mainly significant in the first 6 months. Only, relapse after autologous HCT remained constant over time. Outcomes after allogeneic HCT in patients of 20-40 and >40 years were similar. Autologous and Allogeneic HCT from MUD offer the possibility of long-term survival to patients with MDS/sAML.

Abstract
Forty-two patients with peptic ulceration of the duodenum, stomach or oesophagus, who had not responded to 3 or more months of high-dose treatment with ranitidine (450 or 600 mg/day), were treated with oral lansoprazole at 30-60 mg daily. In 40 patients (95.2%) the ulcers healed within 2-12 weeks. In the remaining 2 patients healing took several months but eventually all ulcers healed. After healing, 40 patients underwent long-term maintenance treatment with 30-60 mg lansoprazole daily for 1-3 years (continuing). During maintenance therapy with lansoprazole, no endoscopically verified relapses occurred when the drug was taken regularly. In 1 patient treatment had to be discontinued because of a drug-related colitis that disappeared soon after treatment had been stopped. There were no significant changes in routine laboratory tests in any patient. Basal serum gastrin concentrations, which were already elevated by the previous high-dose ranitidine treatment (125 +/- 25 pg/ml), rose to four times the normal values after 4 weeks of treatment with lansoprazole (255 +/- 65 pg/ml). Thereafter no further increases in basal serum gastrin concentrations were observed, even after 3 years of administration. The volume density of argyrophilic cells in the oxyntic mucosa increased slightly during lansoprazole treatment; until now no dysplasia of the enterochromaffin-like cells has been observed. In conclusion, 30-60 mg lansoprazole daily healed ranitidine-resistant peptic ulcers, and subsequent maintenance therapy with 30-60 mg lansoprazole daily was found to be highly effective and safe over the time observed.

Abstract
OBJECTIVES Acute limb ischaemia is a common and often lethal clinical event. Reperfusion of an ischaemic limb has been shown to induce a remote gut injury associated with transmigration of endotoxin into the portal and systemic circulation, which in turn has been implicated in the conversion of the sterile inflammatory response to a sepsis syndrome, after lower torso ischaemia-reperfusion injury. This study tests the hypothesis that an anti-endotoxin hyperimmune globulin attenuates ischaemia-reperfusion (I/R) associated sepsis syndrome. DESIGN Prospective, randomised placebo controlled trial, animal experiment. MATERIALS AND METHODS Experimental porcine model, bilateral hind limb I/R injury, randomised to receive anti-endotoxin hyperimmune globulin or placebo. RESULTS Bilateral hind limb I/R injury significantly increased intestinal mucosal acidosis, portal endotoxaemia, plasma cytokine (TNF-alpha, IL-6, IL-8) concentrations, circulating phagocytic cell priming and pulmonary leukosequestration, oedema, and capillary-alveolar protein leak. Conversely, pigs treated with anti-endotoxin hyperimmune globulin (IgG) 20mg/kg at onset of reperfusion had significantly reduced portal endotoxaemia, early circulating phagocytic cell priming, plasma cytokinaemia and attenuation of acute lung injury. CONCLUSIONS Endotoxin translocation across a hyperpermeable gut barrier, phagocytic cell priming and cytokinaemia are key events of limb I/R injury induced systemic inflammation and acute lung injury. This study shows that an anti-endotoxin hyperimmune globulin attenuates portal endotoxaemia, which may reduce early phagocytic cell activation, cytokinaemia and ultimately acute lung injury.

Abstract
UNLABELLED Gepard provides a user-friendly, interactive application for the quick creation of dotplots. It utilizes suffix arrays to reduce the time complexity of dotplot calculation to Theta(m*log n). A client-server mode, which is a novel feature for dotplot creation software, allows the user to calculate dotplots and color them by functional annotation without any prior downloading of sequence or annotation data. AVAILABILITY Both source codes and executable binaries are available at http://mips.gsf.de/services/analysis/gepard

Abstract
In clinical practice, gastrooesophageal reflux (GER) and bronchial asthma often coincide. In the case of sufficient asthma control, the asthma does not need to be taken into account when treatment of GER is being evaluated. In patients with symptomatic asthma despite adequate antiasthmatic treatment, a possible causal relationship between GER and the poor responsiveness to asthma therapy has to be considered. An algorithm to guide the diagnostic and therapeutic steps in such cases is presented.
