Abstract
The compendium of disorders that affect the normal growth or function of the thorax will cause Thoracic Insufficiency Syndrome (TIS). TIS is defined as the inability of the chest to sustain normal breathing and/or lung growth. The etiology of the syndrome may be secondary to spinal deformities, global deformities of the chest, neuromuscular dysfunction or the combination of any these. Its manifestation is based on a history that highlights respiratory symptoms, a physical examination that demonstrates chest deformity, abnormal radiographic findings and/or computed tomography of the chest, accompanied by alterations in lung function or other studies of respiratory function. This syndrome must be treated with haste since it progressively worsens with the aggravation of the underlying condition(s) which is unfavorable to the irreversible physiological changes of the lung that occur during development, and are directly related to the respiratory insufficiencies. The vertical expandable prosthetic titanium rib (VEPTR) was developed as a treatment procedure that aims to restore the volume and function of the thorax with the purpose of enabling thoracic growth during the development of the child or adolescent. The treatment targets the components of the rib cage as a unit, in order to prevent or treat respiratory insufficiencies. Its indications include children with early development scoliosis who are prone to develop SIT. The proposed procedure entails a high incidence of complications and conflicting results that limit its efficacy as a treatment, which is why it is a subject of great controversy in the medical literature.

Abstract
Background Chronic lymphocytic leukemia (CLL) has a heterogeneous clinical course. Beside patients requiring immediate treatment, others show an initial indolent phase followed by progression and others do not progress for decades. The latter two subgroups usually display mutated IGHV genes and a favorable FISH profile. Patients and methods Patients with absence of disease progression for over 10 years (10-34) from diagnosis were defined as ultra-stable CLL (US-CLL). Forty US-CLL underwent extensive characterization including whole exome sequencing (WES), ultra-deep sequencing and copy number aberration (CNA) analysis to define their unexplored genetic landscape. Microarray analysis, comparing US-CLL with non-US-CLL with similar immunogenetic features (mutated IGHV/favorable FISH), was also carried out to recognize US-CLL at diagnosis. Results WES was carried out in 20 US-CLL and 84 non-silent somatic mutations in 78 genes were found. When re-tested in a validation cohort of 20 further US-CLL, no recurrent lesion was identified. No clonal mutations of NOTCH1, BIRC3, SF3B1 and TP53 were found, including ATM and other potential progression driving mutations. CNA analysis identified 31 lesions, none with known poor prognostic impact. No novel recurrent lesion was identified: most cases showed no lesions (38%) or an isolated del(13q) (31%). The expression of 6 genes, selected from a gene expression profile analysis by microarray and quantified by droplet digital PCR on a cohort of 79 CLL (58 US-CLL and 21 non-US-CLL), allowed to build a decision-tree capable of recognizing at diagnosis US-CLL patients. Conclusions The genetic landscape of US-CLL is characterized by the absence of known unfavorable driver mutations/CNA and of novel recurrent genetic lesions. Among CLL patients with favorable immunogenetics, a decision-tree based on the expression of 6 genes may identify at diagnosis patients who are likely to maintain an indolent disease for decades.

Abstract
BACKGROUND Chronic ischemic heart disease take the first place in cause of death in Germany. The proportion of patients aged 75 years or older amounts more than 80 %. Due to their growing part of population the medical care of older patients becomes increasingly important. In this investigation patients aged ≥ 75 years with coronary three-vessel disease were characterized and various treatment strategies were compared. PATIENTS AND METHODS This analysis was retrospective. The data of patients aged 75 years or older with three-vessel disease diagnosed by coronary angiography at the Klinikum Lippe Detmold between 2005 and 2007 were collected. Depending on the received therapy they were parted in three groups: optimal drug therapy (OMT), interventional - (PCI) and surgical revascularization (CABG). Patient characteristics as well as survival- and MACCE-rates during follow up were ascertained. Subgroup analyzes were performed for acute coronary syndrom (ACS) and stable coronary artery disease( CAD). RESULTS The data of 434 patients with an average age of 79 years were documented. 139 (32.0 %) were assigned to the OMT- 189 (43.6 %) to the PCI- and 106 (24.4 %) to the CABG-group. Overall there was no significant difference between the three groups regarding mortality. In the subgroup of patients wit ACS (n = 180) mortality significantly increased in the OMT-group compared to the two invasive therapies (PCI (p = 0.029), CABG (p = 0.045)). The subgroup of patients with stable CAD showed no significant differences in mortality between the three types of therapy. CONCLUSIONS Older patients benefit from an interventional or surgical revascularization in the context of ACS. In contrast, in elderly with stable CAD optimal medical therapy provides a reasonable alternative to invasive therapy without increase in mortality.

Abstract
This EBMT Autoimmune Disease Working Party study aimed to evaluate the influence of CD34+ positive graft selection (CD34+) on the outcome of systemic sclerosis (SSc) patients after autologous hematopoietic stem cell transplantation (AHSCT). Clinical and laboratory data from 138 SSc patients at diagnosis, before and after AHSCT were retrospectively analyzed. CD34+ selection was performed in 47.1% (n=65) patients. By multivariate analysis adjusting for all factors differing between the two groups (without or with CD34+), there was no statistically significant difference in terms of overall survival (hazard ratio (HR): 0.98, 95% confidence interval (CI) 0.40-2.39, P=0.96), PFS (HR: 1.55, 95% CI 0.83-2.88, P=0.17) and incidence of relapse or progression (HR: 1.70, 95% CI 0.85-3.38, P=0.13). We demonstrate that CD34+ does not add benefit to the outcome of SSc patient treated with AHSCT. These findings should be further confirmed by prospective randomized trials.

Abstract
BACKGROUND The incidence of chronic myeloid leukemia (CML) increases with age, but it is unclear how the characteristics of the disease vary with age. In children, where CML is very rare, it presents with more aggressive features, including huge splenomegaly, higher cell count and higher blast cell percentage. PATIENTS AND METHODS To investigate if after childhood the disease maintains or loses these characteristics of aggressiveness, we analyzed 2784 adult patients, at least 18 years old, registered by GIMEMA CML WP over a 40-year period. RESULTS Young adults (YAs: 18-29 years old) significantly differed from adults (30-59 years old) and elderly patients (at least 60 years old) particularly for the frequency of splenomegaly (71%, 63% and 55%, P < 0.001), and the greater spleen size (median value: 4.5, 3.0 and 1.0 cm, P < 0.001). According to the EUTOS score, that is age-independent, high-risk patients were more frequent among YAs, than among adult and elderly patients (18%, 9% and 6%, P < 0.001). In tyrosine kinase inhibitors-treated patients, the rates of complete cytogenetic and major molecular response were lower in YAs, and the probability of transformation was higher (16%, 5% and 7%, P = 0.011). CONCLUSIONS The characteristics of CML or the host response to leukemia differ with age. The knowledge of these differences and of their causes may help to refine the treatment and to improve the outcome. CLINICAL TRIAL NUMBERS NCT00510926, NCT00514488, NCT00769327, NCT00481052.

Abstract
This report is about a married couple who were admitted to hospital suffering from gastrointestinal complaints after eating mushrooms. With the suspicion of poisoning with Amanita phalloides treatment started with elimination of the toxins, symptomatic therapy and specific therapy with silibinin. After quantitative determination of the Amanita toxins the patients were immediately transferred to a university hospital.Poisoning by the death cap mushroom is responsible for acute hepatic and often also renal failure and is accompanied by a high mortality. Clinical symptoms follow a three-phase course with gastrointestinal complaints, an asymptomatic interval and finally the hepatorenal phase. Even in suspected cases of intoxication, treatment should be started by antidote therapy with silibinin.

Abstract
The Hema e-Chart prospectively collected data on febrile events (FEs) in hematological malignancy patients (HMs). The aim of the study was to assess the number, causes and outcome of HM-related FEs. Data were collected in a computerized registry that systematically approached the study and the evolution of FEs developing in a cohort of adult HMs who were admitted to 19 hematology departments in Italy from March 2007 to December 2008. A total of 869 FEs in 3,197 patients with newly diagnosed HMs were recorded. Fever of unidentified origin (FUO) was observed in 386 cases (44.4%). The other causes of FE were identified as noninfectious in 48 cases (5.5%) and infectious in 435 cases (50.1%). Bacteria were the most common cause of infectious FEs (301 cases), followed by fungi (95 cases), and viruses (7 cases). Mixed agents were isolated in 32 episodes. The attributable mortality rate was 6.7% (58 FEs). No deaths were observed in viral infection or in the noninfectious groups, while 25 deaths were due to FUO, 16 to bacterial infections, 14 to fungal infections, and three to mixed infections. The Hema e-Chart provided a complete system for the epidemiological study of infectious complications in HMs.

Abstract
Haemodialysis patients have few endothelial progenitor cells (EPCs) and an unfavourable cardiovascular outcome. The effects on peripheral blood CD34(+) cells and EPCs of a 6-month walking exercise programme were studied. Thirty dialysis patients (20 males, age 67 +/- 12 years) were prescribed exercise (two daily 10-min home walking sessions at moderate intensity, group E, n = 16) or not prescribed exercise (control, group C, n = 14). On entry and after 6 months peripheral blood CD34(+) cells, EPCs (assessed as CD34(+) cells co-expressing AC133 and vascular endothelial growth factor receptor 2 [VEGFR2], and as endothelial colony-forming units [e-CFU]) and exercise capacity (6-min walking distance, 6MWD) were evaluated. In group E, 6MWD and e-CFU increased significantly during the study period, with no significant changes in CD34(+) or CD34(+) AC133(+) VEGFR2(+) cell numbers. The change in e-CFU was directly and significantly correlated to patient-reported training load. Group C showed no significant change in any variable. In haemodialysis patients, moderate-intensity exercise selectively increased the number of e-CFU.

Abstract
Although recent consensus has clearly defined chronic total occlusions (CTO), attempted percutaneous coronary intervention (PCI) remains low. Histopathologically, CTOs are characterized by fibrous caps, varying degrees of plaques, and neovascularization, with both increasing with the age of the CTO. Multiple registries and studies show that successful PCI of CTOs can improve symptoms, left ventricular function, and mortality. There is overwhelming evidence that very low restenosis and reocclusion rates can be obtained with drug eluting stents after recanalization of CTOs. PCI should be considered the preferred initial revascularization modality in patients in whom a high procedural success rate may be anticipated. Novel techniques have greatly enhanced procedural success, and include ''parallel'' and ''seesaw'' wire techniques, balloon anchoring, subintimal tracking and reentry (STAR), retrograde approach, contralateral injection, and intravascular ultrasound (IVUS) guidance. Improvements in wire technology have largely been responsible for improved procedural success in PCI of CTO, while application of new technologies hold promise to significantly better outcomes. Magnetic resonance imaging (MRI) and multislice computed tomography (CT) are already employed in formulating treatment strategies and their role in the treatment of CTOs is likely to increase.

Abstract
BACKGROUND It has been suggested that soluble factors produced by bone marrow (BM) mesenchymal stromal cells (MSC) play a fundamental role in mediating immune modulation. HLA-G antigens (Ag) are major histocompatibility complex (MHC) class Ib molecules characterized by a limited polymorphism and a splicing mechanism that regulates the production of membrane-bound and soluble isoforms. Interleukin-10 (IL-10) cytokine is one of the main up-modulators of soluble HLA-G Ag (sHLA-G) production by CD14+ peripheral blood monocyte cells and increased IL-10 levels are reported to be associated with MSC immune modulation. METHODS We investigated, by specific enzyme-linked immunosorbent assay (ELISA), the possible role of sHLA-G molecules in the inhibition of the peripheral blood mononuclear cell (PBMC) response to phytohemagglutinin (PHA) mediated by MSC from different sources. RESULTS There was a significant correlation between the presence of increased levels of sHLA-G and IL-10 in the MSC/PBMC/PHA culture supernatants and lymphoproliferative inhibition. Neutralizing experiments performed with monoclonal Ab directed against HLA-G and IL-10 molecules confirmed the inhibitory ability of sHLA-G Ag. Furthermore, exogenous IL-10 induced sHLA-G molecule secretion by MSC alone in a polymorphic way, while a longitudinal analysis confirmed the loss of MSC inhibitory functions in relation to in vitro MSC aging. DISCUSSION Overall the results obtained suggest a functional role for sHLA-G molecules in inhibiting the PBMC response mediated by MSC. Moreover, the ability of IL-10 to induce sHLA-G Ag production by MSC alone could be proposed as a marker of MSC functional ability.

Abstract
BACKGROUND Little is known about human mesenchymal stromal cell (hMSC) phenotypic and functional subsets in response to environmental stimuli. The strategy used in this study focused on defining hMSC functional subpopulations based in particular on their Thy-1 (CD90) antigen (Ag) surface expression. METHODS The effect of different in vitro microenvironmental conditions on the isolation and expansion of bone marrow-derived (BM) hMSC from hematologic malignancies (HM) and normal samples (NS) was assayed. hMSC clonogenic and differentiation potential, phenotypic profile and long-term capacity to sustain in vitro hemopoiesis were considered in relation to the different expansion protocols. RESULTS The results showed that angiogenic supplements used in combination with low serum content gave rise to the appearance of Thy-1(-) HM-MSC with high proliferative potential, capable of restoring the typical HM stromal impairment. The expression of the CD271 was partially maintained. We further report an enhancement towards the osteogenic and adipogenic differentiation capacity by the Thy-1(-) HM-MSC subset. Despite the angiogenic treatment, the Thy-1(-) MSC stopped short of full endothelial differentiation. DISCUSSION In this paper we provide evidence that in vitro angiogenic stimuli generate HM-MSC lacking CD90 Ag expression. The Thy-1(-) MSC subset is characterized by peculiar functional and phenotypic characteristics, thus supporting the role played by the microenvironment in selecting particular hMSC subsets maintaining normal tissue homeostasis or inducing pathologic processes.

Abstract
BACKGROUND The acute coronary syndrome (ACS) remains a major cause of mortality and morbidity in the western world. The Global Registry of Acute Coronary Events (GRACE) documents inpatients with all types of ACS and a follow-up at three months in Germany and worldwide. METHODS The data of the German Cluster Detmold were compared with data from the worldwide GRACE registry (31,070 patients). Data from 849 patients with ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA) were collected from October 2001 to September 2005 in eight participating hospitals in the GRACE2 Cluster Detmold. RESULTS Compared with the worldwide GRACE data the patients in the Cluster Detmold had longer pre-hospital admission times (STEMI patients < 1 h: 13.9 % vs. 17.0 %; p < 0.05); more frequent interventions (PCI 60.1 % vs. 48.7%; p < 0.001) and less thrombolysis (17.9 vs. 42.5%; p < 0.001) in STEMI patients; more frequent use of platelet inhibitors (clopidogrel and ticlopidine, 93.4 % vs. 89.4%; p < 0.001) and unfractionated heparin (69.8 % vs. 36.5; p < 0.001), and less frequent use of low molecular weight heparin (31.1 % vs. 51.2%; p < 0.001); more frequent use of RAS blocking agents (80.2 vs. 66.6, p < 0.001) and beta blockers (87.4 vs. 78.8, p < 0.001) and less frequent use of lipid lowering agents (23.5 vs. 72.5%; p < 0.001). CONCLUSIONS Current management of ACS in Germany closely follows the recommendations of the German society of Cardiology. Differences in practice may account for the observed substantially lower event rates in Germany during hospitalization, but there is still room for improvement in the pre-hospital phase und in the degree to which pharmacotherapy is used for secondary prevention.

Abstract
HISTORY A 19-year-old man with congestive heart failure reported recent onset of exercise-induced dyspnea and pitting edema of the face. He also developed increasing muscular weakness. Three years before the diagnosis of autosomal-dominant Emery-Dreifuss muscular dystrophy (EDMD) had been made. FINDINGS Cardiac and lung auscultation were unremarkable. The heart rate was 102 /min, and the blood pressure 100/70 mmHg. Aspartate aminotransferase (62 U/l) and lactate dehydrogensase (361 U/l) were elevated. The electrocardiogram during telemetric monitoring showed a 2 AV block, Mobitz type II. Echocardiography showed an ejection fraction of 20%. Coronary atherosclerosis was excluded by coronary angiography. A raised pulmonary wedge pressure at rest was recorded through an indwelling Swan-Ganz catheter, but cardiac output was normal. Histopathology revealed findings typical for dilated cardiomyopathy. THERAPY AND COURSE The patient was already on diuretics when admitted; other medication included an ACE inhibitor, beta-blocker, aldosterone antagonist and digitalis. A cardioverter-defibrillator was implanted prophylactically. Congestive heart failure developed during the subsequent months. Two years later the patient underwent orthotopic heart transplantation. CONCLUSION In patients with genetically determined neuromuscular diseases it is prognostically important early to recognize cardiomyopathy and cardiac arrhythmias. Subsequent cardiac transplantation may be life-saving.

Abstract
Six patients with de novo acute myeloid leukemia (AML) and a t(2;3)(p15-21;q26-27) were identified among approximately 1000 cases enrolled in the GIMEMA trial. The t(2;3) was the sole anomaly in three patients, whereas in three cases monosomy 7, trisomy 15 and 22, and trisomy 14 represented additional aberrations. No cryptic chromosome deletions at 5q, 7q, 12p, and 20q were observed. One patient carried a FLT3 D835 mutation; FLT3 internal tandem duplication (ITD) was not detected in three patients tested. Characterization of the translocation breakpoints using a 3q26 BAC contig specific for the PRDM3 locus showed that the breakpoints were located 5' to EVIl as follows: within myelodysplatic syndrome (MDS) intron 1 (# 3), between MDS1 exons 2 and 3 in three patients (# 1, 2, 4) with a 170bp cryptic deletion distal to the breakpoint in one (# 2), and in a more centromeric position spanning from intron 2 to the 5' region of EVI1 (# 6, 5). A set of 2p16-21 BAC probes showed that the breakpoints on chromosome 2p were located within BCL11A in two separate regions (# 1, 4 and # 2-5), within the thyroid adenoma-associated (THADA) gene (# 6) or distal to the ZFP36L2 locus (# 3). Regulatory elements were present in proximity of these breakpoints. RACE PCR studies revealed a chimeric transcript in 1/6 patient analyzed, but no fusion protein. Quantitative PCR showed a 21-58-fold over-expression of the EVIl gene in all cases analyzed. The patients showed dysplasia of at least two myeloid cell lineages in all cases; they had a low-to-normal platelet count and displayed an immature CD34+ CD117+ immunophenotype. Despite intensive chemotherapy and a median age of 43 years (range 36-59), only two patients attained a short-lived response; one patient is alive with active disease at 12 months, five died at 4-14 months. We arrived at the following conclusions: (a) the t(2;3) is a recurrent translocation having an approximate 0.5% incidence in adult AML; (b) breakpoints involve the 5' region of EVIl at 3q26, and the BCL11A, the THADA gene or other regions at 2p16.1-21; (c) cryptic deletions distal to the 3q26 breakpoint may occur in some cases; (d) the juxtaposition of the 5' region of EVIl with regulatory elements normally located on chromosome 2 brings about EVI1 overexpression; (e) clinical outcome in these cases is severe.

Abstract
Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) has a dismal prognosis. We prospectively evaluated minimal residual disease (MRD) by measuring BCR/ ABL levels with a quantitative real-time PCR procedure after induction and after consolidation in 45 adults with Ph+ ALL who obtained complete hematological remission after a high-dose daunorubicin induction schedule. At diagnosis, the mean BCR-ABL/GUS ratio was 1.55 +/- 1.78. A total of 42 patients evaluable for outcome analysis were operationally divided into two MRD groups: good molecular responders (GMRs; n = 28) with > 2 log reduction of residual disease after induction and > 3 log reduction after consolidation therapy, and poor molecular responders (PMRs; n = 14) who, despite complete hematological remission, had a higher MRD at both time points. In GMR, the actuarial probability of relapse-free, disease-free and overall survival at two years was 38, 27 and 48%, respectively, as compared to 0, 0 and 0% in PMR (P = 0.0035, 0.0076 and 0.0026, respectively). Salvage therapy induced a second sustained complete hematological remission in three GMR patients, but in no PMR patient. Our data indicate that, as already shown in children, adult Ph+ ALL patients have a heterogeneous sensitivity to treatment, and that early quantification of residual disease is a prognostic parameter in this disease.

Abstract
In the present paper we report pericentric chromosome 8 inversions in two (2.4%) of 82 acute myeloid leukemia (AML) cases characterized by the 5'RUNX1/3'CBFA2T1 fusion gene. Molecular cytogenetic characterization was achieved using appropriate bacterial artificial chromosome (BAC) and P1 artificial chromosome (PAC) probes in fluorescence in situ hybridization (FISH) experiments. In these two cases the fusion gene was detected on the der(8) short arm, resulting from a pericentric chromosome 8 inversion followed by a t(8;21) rearrangement. These results suggest that heterogeneous mechanisms can lead to the generation of the 5'RUNX1/3'CBFA2T1chimeric gene.

Abstract
Cytogenetic and fluorescence in situ hybridization studies were successfully performed in 217 chronic lymphocytic leukemia (CLL). In all, 13 patients with 6q21 deletion were identified and characterized in comparison with 92 patients with 'favourable' karyotype (normal or 13q-), 69 cases with 'intermediate risk' (1-2 anomalies) and 43 cases with 'unfavourable' karyotype (complex, 11q- or 17p-). Six out of 13 cases with 6q- showed an excess of atypical lymphocytes, a finding confirmed at the histologic level; >20% CD38+ cells were seen in 5/6 cases. IGVH mutational status revealed >98% homology to the germline sequence in 4/10 cases. When compared with the 'favourable' group, patients with 6q- showed a higher white blood cell (WBC) count, frequent splenomegaly, atypical morphology, CD38+ and short time from diagnosis to first treatment and short survival. A higher median WBC count was found in the 6q- group vs the intermediate-risk group; survival was shorter in the unfavourable group. To ascertain if the 6q- anomaly was an independent factor predicting for an inferior outcome among those patients with 'favourable' cytogenetics, we performed an analysis of prognostic factors in 105 patients (92 'favourable' plus 13 with 6q-), showing that the 6q- chromosome maintained its prognostic significance at multivariate analysis (P=0.02) along with stage (P=0.01). We conclude that CLL with 6q- is characterized by a high incidence of atypical morphology, classical immunophenotype with CD38 positivity and intermediate incidence of IGVH somatic hypermutation. Clinicobiological features and outcome show that this cytogenetic subset of CLL should be allocated in an intermediate-risk category.

Abstract
The Authors report three cases of appendiceal carcinoids, found during appendectomy for acute appendicitis during the last 15 years. Appendiceal carcinoid is a rare neoplasm, more frequent in females age ranging between 20 and 29 years. Lack of symptoms explains the occasional diagnosis of this disease. The prognosis is related mostly to the size of the tumor, local and lymphatic invasion, presence of metastases, localization inside the appendix, histological type and age of the patient. Therapy is mainly surgical and consists of appendectomy and right colectomy according to different criteria which are being discussed in this article.

Abstract
The t(9;22)(q34;q11), generating the Philadelphia chromosome (Ph), is found in more than 90% of patients with chronic myeloid leukemia (CML) and in 15-30% of adults with acute lymphoblastic leukemia (ALL). Different groups have recently described the presence of large genomic deletions adjacent to the translocation breakpoint on the derivative chromosome 9 in 9-16% of CML patients. In the present paper, we report a FISH study of 45 Ph+ adult ALL patients with the aim of investigating the presence of deletions on derivative chromosome 9. In four (9%) of 45 cases, all showing an M-bcr, we detected deletions on der(9). The frequency of deletions we observed is similar to that reported in CML patients. The association of an M-bcr breakpoint and deletions appears significant (P=0.03). Some authors have suggested a very low incidence of der(9) deletions in ALL. This discrepancy can be explained by taking into account the low percentage of M-bcr ALL patients in the latter study (18%) compared to the present one (44%).

Abstract
To better define the incidence and significance of cryptic chromosome lesions in acute myeloid leukemia (AML), fluorescence in situ hybridization (FISH) studies were performed in interphase cells and, when appropriate, in metaphase cells and in morphologically intact BM smears. Fifty-five adult de novo AML (group A) and 27 elderly AML or AML after myelodysplastic syndrome (AML-MDS) (group B) were tested using probes detecting the following anomalies: -5, -7, +8, deletions of 5q31, 7q31, 12p13/ETV6, 17p13/p53, 20q11. All the patients had a normal karyotype in more than 20 cells and tested negative for the common AML-associated fusion genes. No patient in group A was found to carry occult chromosome anomalies, whereas 8/27 patients in group B (P < 0.0001) showed 5q31 or 7q31 deletion (three cases each), a 17p13/p53deletion or trisomy 8 (one case each) in 33-60% interphase cells. Metaphase cells showed only one hybridization signal at 5q31 (three cases) and 7q31 (one case), whereas two normal signals at 7q31 and chromosome 8 centromeres were seen in two patients with 7q deletion and trisomy 8 in interphase cells. The majority of blast cells (76-94%) carried the chromosome anomaly in all cases; erythroid involvement in a minority of cells was seen in three patients. In group B, the presence of occult chromosome anomalies was associated with exposure to myelotoxic agents in the workplace (5/8 cases vs 3/19, P = 0.026) and with a lower complete remission rate (0/6 patients vs 7/12, P = 0.024). We arrived at the following conclusions: (1) cryptic chromosome deletions in the order of a few hundred kb magnitude may be found in a fraction of elderly AML or MDS-related AML and not in de novo adult AML with normal karyotype; (2) these chromosome lesions are usually represented by submicroscopic rearrangements; (3) they display a specific pattern of cell-lineage involvement arguing in favor of their role in the outgrowth of the leukemic blast cells; (4) they are associated with a history of exposure to myelotoxic agents in the workplace and, possibly, with resistance to induction treatment.

Preferential expression of the transcription coactivator HTIF1alpha gene in acute myeloid leukemia and MDS-related AML. Leukemia 2002; 16:886-93.

Abstract
HTIF1alpha, a transcription coactivator which is able to mediate RARalpha activity and functionally interact with PML, is encoded by a gene on chromosome 7q32-34, which is a critical region in acute myeloid leukemias (AML). With the assumption that this gene may be related to AML, we investigated the HTIF1alpha DNA structure and RNA expression in leukemic cells from 36 M1-M5 AML patients (28 "de novo" and eight "secondary" to myelodysplastic syndrome (MDS)). Abnormal HTIF1alpha DNA fragments were never found, whereas loss of HTIF1alpha DNA was observed in the patients with chromosome 7q32 deletion and translocation, and in one case without detectable chromosome 7 abnormality. HTIF1alpha RNA was found in acute myelocytic leukemic blasts, and was almost undetectable in normal mononuclear cells. The expression varied among the patients: higher in M1 to M3 subtypes, with the highest values in M1; low levels were constantly observed in M4 and M5 AML. In addition, HTIF1alpha was significantly overexpressed in MDS-related AML (MDR-AML), but not in MDS. We also found that HTIF1alpha expression was high in myeloid cell lines. In myeloblastic HL60 and promyelocytic NB4 cells, induced to differentiate along the monocytic-macrophage pathway by TPA or vitamin D3, HTIF1alpha expression decreased, whereas it was maintained at high levels on induction to granulocytic differentiation by RA or DMSO. In K562 cells, HTIF1alpha RNA levels did not change after hemin-induced erythroid differentiation. These results suggest that HTIF1alpha could play a role in myeloid differentiation, being distinctly regulated in hematopoietic lineages.
