Abstract
Fast time-gated single-photon detectors demonstrated high depth sensitivity in the detection of localized absorption perturbations inside scattering media, but their use for in vivo clinical applications-such as functional imaging of brain activation-was impaired by their small (<0.04mm2) active area. Here, we demonstrate, both on phantoms and in vivo, the performance of a fast-gated digital silicon photomultiplier (SiPM) that features an overall active area of 8.6mm2, overcoming the photon collection capability of established time-gated single-pixel detectors by orders of magnitude, enabling deep investigations within scattering media and high signal-to-noise ratios at late photon arrival times.

Abstract
The versatility of silicon photonic integrated circuits has led to a widespread usage of this platform for quantum information-based applications, including quantum key distribution (QKD). However, the integration of simple high-repetition-rate photon sources is yet to be achieved. The use of weak-coherent pulses (WCPs) could represent a viable solution. For example, measurement device independent QKD (MDI-QKD) envisions the use of WCPs to distill a secret key immune to detector side channel attacks at large distances. Thus, the integration of III-V lasers on silicon waveguides is an interesting prospect for quantum photonics. Here we report the experimental observation of Hong-Ou-Mandel interference with 46±2% visibility between WCPs generated by two independent III-V on silicon waveguide integrated lasers. This quantum interference effect is at the heart of many applications, including MDI-QKD. This Letter represents a substantial first step towards an implementation of MDI-QKD fully integrated in silicon and could be beneficial for other applications such as standard QKD and novel quantum communication protocols.

Abstract
Aim The occurrence of unilateral involvement in bilateral bone marrow trephine biopsies in non-Hodgkin's lymphomas (NHL) at disease onset (10-20% of cases) has been reported since the early 70s. Therefore, although these studies were based on small series, the use of bilateral bone marrow biopsies has become the rule. However, the clinical value of this procedure has never been clearly established. The aim of the present study was to ascertain the true value of bilateral bone marrow biopsy in the staging of NHL. Study Design We examined 368 cases of NHL (A-H according to the Working Formulation) (WF), without leukemic involvement of the peripheral blood, in order to evaluate: 1) the incidence of unilateral bone marrow involvement; 2) the percentage of patients who, as a result of unilateral bone marrow involvement, changed from stages I-II to stage IV; 3) assessment of response to therapy for patients with both bilateral or unilateral bone marrow involvement. Results In the A-C NHL groups of WF there was a unilateral bone marrow involvement of 8.8%. Overall, bone marrow involvement induced a change from clinical stages I-II to stage IV in 5.6% of cases, a figure which would correspond to a false negative rate of 2.8%, if unilateral bone marrow biopsy was performed. In the D-F and G, H groups of WF, unilateral involvement was 10.1% and 8.5% respectively; the change in stage from I-II to IV by unilateral bone marrow involvement respectively amounted to 1.4% and 2.8%, which correspond to respective false negative rates of 0.7% and 1.4%. Conclusions On the basis of these results and of the present therapeutic strategies, we propose: bilateral bone marrow biopsy for clinical stages I-II of all NHL; no bone marrow biopsy at disease onset for clinical stages III and IV of A to H histologic subtypes of the WF; unilateral bone marrow biopsy (A-C subtypes of the WF) or bilateral (D-H of the WF), after the regression of extramedullary localizations.

Abstract
One of the most intriguing aspects of quantum mechanics is the impossibility of measuring at the same time observables corresponding to noncommuting operators, because of quantum uncertainty. This impossibility can be partially relaxed when considering joint or sequential weak value evaluation. Indeed, weak value measurements have been a real breakthrough in the quantum measurement framework that is of the utmost interest from both a fundamental and an applicative point of view. In this Letter, we show how we realized for the first time a sequential weak value evaluation of two incompatible observables using a genuine single-photon experiment. These (sometimes anomalous) sequential weak values revealed the single-operator weak values, as well as the local correlation between them.

Abstract
Weak value measurements have recently given rise to a great amount of interest in both the possibility of measurement amplification and the chance for further quantum mechanics foundations investigation. In particular, a question emerged about weak values being proof of the incompatibility between quantum mechanics and noncontextual hidden variables theories (NCHVTs). A test to provide a conclusive answer to this question was given by Pusey [Phys. Rev. Lett. 113, 200401 (2014)], where a theorem was derived showing the NCHVT incompatibility with the observation of anomalous weak values under specific conditions. In this Letter we realize this proposal, clearly pointing out the connection between weak values and the contextual nature of quantum mechanics.

Abstract
Poli et al. present genetic and proteomic analyses from budding yeast that uncover links between the DNA replication checkpoint sensor Mec1–Ddc2 (ATR–ATRIP), the chromatin remodeling complex INO80C, and the transcription complex PAF1C. A subset of chromatin-bound RNAPII is degraded in a manner dependent on Mec1, INO80, and PAF1 complexes in cells exposed to hydroxyurea. Little is known about how cells ensure DNA replication in the face of RNA polymerase II (RNAPII)-mediated transcription, especially under conditions of replicative stress. Here we present genetic and proteomic analyses from budding yeast that uncover links between the DNA replication checkpoint sensor Mec1–Ddc2 (ATR–ATRIP), the chromatin remodeling complex INO80C (INO80 complex), and the transcription complex PAF1C (PAF1 complex). We found that a subset of chromatin-bound RNAPII is degraded in a manner dependent on Mec1, INO80, and PAF1 complexes in cells exposed to hydroxyurea (HU). On HU, Mec1 triggers the efficient removal of PAF1C and RNAPII from transcribed genes near early firing origins. Failure to evict RNAPII correlates inversely with recovery from replication stress: paf1Δ cells, like ino80 and mec1 mutants, fail to restart forks efficiently after stalling. Our data reveal unexpected synergies between INO80C, Mec1, and PAF1C in the maintenance of genome integrity and suggest a mechanism of RNAPII degradation that reduces transcription–replication fork collision.

Abstract
As building blocks of diverse macromolecular complexes, the AAA+ ATPases Rvb1 and Rvb2 are crucial for many cellular activities including cancer-related processes. Their oligomeric structure and function remain unclear. We report the crystal structures of full-length heteromeric Rvb1·Rvb2 complexes in distinct nucleotide binding states. Chaetomium thermophilum Rvb1·Rvb2 assemble into hexameric rings of alternating molecules and into stable dodecamers. Intriguingly, the characteristic oligonucleotide-binding (OB) fold domains (DIIs) of Rvb1 and Rvb2 occupy unequal places relative to the compact AAA+ core ring. While Rvb1's DII forms contacts between hexamers, Rvb2's DII is rotated 100° outward, occupying lateral positions. ATP was retained bound to Rvb1 but not Rvb2 throughout purification, suggesting nonconcerted ATPase activities and nucleotide binding. Significant conformational differences between nucleotide-free and ATP-/ADP-bound states in the crystal structures and in solution suggest that the functional role of Rvb1·Rvb2 is mediated by highly interconnected structural switches. Our structures provide an atomic framework for dodecameric states and Rvb1·Rvb2's conformational plasticity.

Abstract
We present a Time-to-Digital Converter (TDC) card with a compact form factor, suitable for multichannel timing instruments or for integration into more complex systems. The TDC Card provides 10 ps timing resolution over the whole measurement range, which is selectable from 160 ns up to 10 μs, reaching 21 ps rms precision, 1.25% LSB rms differential nonlinearity, up to 3 Mconversion/s with 400 mW power consumption. The I/O edge card connector provides timing data readout through either a parallel bus or a 100 MHz serial interface and further measurement information like input signal rate and valid conversion rate (typically useful for time-correlated single-photon counting application) through an independent serial link.

Abstract
OBJECTIVE A number of studies have shown the role of expanded Bone Marrow-derived Mesenchymal Stem Cells in the repair and regeneration of musculo-skeletal tissues. The current European regulations define in vitro expanded cells for clinical purposes as substantially manipulated and include them in the class of Advanced-Therapy Medicinal Products to be manufactured in compliance with current Good Manufacturing Practice. Among the characteristics that such cells should display, genomic stability has recently become a major safety concern. The aim of this study is to perform a chromosomal and genetic characterization of Bone Marrow-derived Mesenchymal Stem Cells expanded in compliance with Good Manufacturing Practice for a potential clinical use in orthopaedics. MATERIALS AND METHODS Mesenchymal Stem Cells, isolated from bone marrow, were expanded for six weeks in compliance with current Good Manufacturing Practice. DNA profiling analyses were applied to test cross-contamination absence. Genomic stability was evaluated by means of karyotyping, sequencing of TP53, p21/CDKN1A and MDM2 genes and the expression analysis of c-MYC and H-RAS oncogenes, p21/CDKN1A, TP53, p16/CDKN2A, RB1 and p27/CDKN1B tumor suppressor genes and hTERT gene. RESULTS The DNA profiling analysis showed a unique genetic profile for each Mesenchymal Stem Cell culture, indicating the absence of cross-contamination. Karyotyping evidentiated some chromosomal abnormalities within the 10% limit set by the Cell Products Working Party review, except for one patient. In all cases, the molecular biology analyses did not revealed DNA point mutations, acquisition or changes in gene expression. hTERT levels were undetectable. CONCLUSIONS Cultured Mesenchymal Stem Cells do not seem to be prone to malignant transformation. In fact, although some chromosomal aberrations were found, molecular biology analyses demonstrated that the expansion phase did not induce the acquisition of de novo genetic changes.

Abstract
INO80/SWR1 family chromatin remodelers are complexes composed of >15 subunits and molecular masses exceeding 1 MDa. Their important role in transcription and genome maintenance is exchanging the histone variants H2A and H2A.Z. We report the architecture of S. cerevisiae INO80 using an integrative approach of electron microscopy, crosslinking and mass spectrometry. INO80 has an embryo-shaped head-neck-body-foot architecture and shows dynamic open and closed conformations. We can assign an Rvb1/Rvb2 heterododecamer to the head in close contact with the Ino80 Snf2 domain, Ies2, and the Arp5 module at the neck. The high-affinity nucleosome-binding Nhp10 module localizes to the body, whereas the module that contains actin, Arp4, and Arp8 maps to the foot. Structural and biochemical analyses indicate that the nucleosome is bound at the concave surface near the neck, flanked by the Rvb1/2 and Arp8 modules. Our analysis establishes a structural and functional framework for this family of large remodelers.

Abstract
We report on the design and first in vivo tests of a novel non-contact scanning imaging system for time-domain near-infrared spectroscopy. Our system is based on a null source-detector separation approach and utilizes polarization-selective detection and a fast-gated single-photon avalanche diode to record late photons only. The in-vivo tests included the recording of hemodynamics during arm occlusion and two brain activation tasks. Localized and non-localized changes in oxy- and deoxyhemoglobin concentration were detected for motor and cognitive tasks, respectively. The tests demonstrate the feasibility of non-contact imaging of absorption changes in deeper tissues.

Abstract
"Indirect" time-of-flight is one technique to obtain depth-resolved images through active illumination that is becoming more popular in the recent years. Several methods and light timing patterns are used nowadays, aimed at improving measurement precision with smarter algorithms, while using less and less light power. Purpose of this work is to present an indirect time-of-flight imaging camera based on pulsed-light active illumination and a 32 × 32 single-photon avalanche diode array with an improved illumination timing pattern, able to increase depth resolution and to reach single-photon level sensitivity.

Abstract
We present a compact high performance time-to-digital converter (TDC) module that provides 10 ps timing resolution, 160 ns dynamic range and a differential non-linearity better than 1.5% LSB(rms). The TDC can be operated either as a general-purpose time-interval measurement device, when receiving external START and STOP pulses, or in photon-timing mode, when employing the on-chip SPAD (single photon avalanche diode) detector for detecting photons and time-tagging them. The instrument precision is 15 ps(rms) (i.e., 36 ps(FWHM)) and in photon timing mode it is still better than 70 ps(FWHM). The USB link to the remote PC allows the easy setting of measurement parameters, the fast download of acquired data, and their visualization and storing via an user-friendly software interface. The module proves to be the best candidate for a wide variety of applications such as: fluorescence lifetime imaging, time-of-flight ranging measurements, time-resolved positron emission tomography, single-molecule spectroscopy, fluorescence correlation spectroscopy, diffuse optical tomography, optical time-domain reflectometry, quantum optics, etc.

Abstract
We report results of the proof-of-principle tests of a novel non-contact tissue imaging system. The system utilizes a quasi-null source-detector separation approach for time-domain near-infrared spectroscopy, taking advantage of an innovative state-of-the-art fast-gated single photon counting detector. Measurements on phantoms demonstrate the feasibility of the non-contact approach for the detection of optically absorbing perturbations buried up to a few centimeters beneath the surface of a tissue-like turbid medium. The measured depth sensitivity and spatial resolution of the new system are close to the values predicted by Monte Carlo simulations for the inhomogeneous medium and an ideal fast-gated detector, thus proving the feasibility of the non-contact approach for high density diffuse reflectance measurements on tissue. Potential applications of the system are also discussed.

Abstract
BACKGROUND AND PURPOSE Adenosine is an endogenous modulator, interacting with four G-protein coupled receptors (A(1), A(2A), A(2B) and A(3)) and acts as a potent inhibitor of inflammatory processes in several tissues. So far, the functional effects modulated by adenosine receptors on human synoviocytes have not been investigated in detail. We evaluated mRNA, the protein levels, the functional role of adenosine receptors and their pharmacological modulation in human synoviocytes. EXPERIMENTAL APPROACH mRNA, Western blotting, saturation and competition binding experiments, cyclic AMP, p38 mitogen-activated protein kinases (MAPKs) and nuclear factor (NF)-kappaB activation, tumour necrosis factor alpha (TNF-alpha) and interleukin-8 (IL-8) release were assessed in human synoviocytes isolated from patients with osteoarthritis. KEY RESULTS mRNA and protein for A(1), A(2A), A(2B) and A(3) adenosine receptors are expressed in human synoviocytes. Standard adenosine agonists and antagonists showed affinity values in the nanomolar range and were coupled to stimulation or inhibition of adenylyl cyclase. Activation of A(2A) and A(3) adenosine receptors inhibited p38 MAPK and NF-kappaB pathways, an effect abolished by selective adenosine antagonists. A(2A) and A(3) receptor agonists decreased TNF-alpha and IL-8 production. The phosphoinositide 3-kinase or G(s) pathways were involved in the functional responses of A(3) or A(2A) adenosine receptors. Synoviocyte A(1) and A(2B) adenosine receptors were not implicated in the inflammatory process whereas stimulation of A(2A) and A(3) adenosine receptors was closely associated with a down-regulation of the inflammatory status. CONCLUSIONS AND IMPLICATIONS These results indicate that A(2A) and A(3) adenosine receptors may represent a potential target in therapeutic modulation of joint inflammation.

Abstract
AIMS Heterozygous activating mutations in KCNJ11, which encodes the Kir6.2 subunit of the pancreatic ATP-sensitive potassium (K(ATP)) channel, cause both permanent and transient neonatal diabetes. Identification of KCNJ11 mutations has important therapeutic implications, as many patients can replace insulin injections with sulphonylurea tablets. The aim was to determine if a KCNJ11 mutation was responsible for a dominantly inherited form of diabetes mellitus, showing variability in age at diagnosis, in an Italian family. METHODS We sequenced KCNJ11 in members of a three-generation family with variable phenotypes of dominantly inherited diabetes mellitus. One had transient early-onset diabetes, one had impaired glucose tolerance during the second pregnancy, and two had young-onset diabetes. None of the subjects showed permanent neonatal diabetes or neurological symptoms. RESULTS A novel heterozygous mutation (c. 679C-->G and c. 680A-->T) was identified, resulting in a GAG-->CTG (E227L) substitution in KCNJ11. Functional studies of recombinant heterozygous K(ATP) channels revealed a small reduction in channel inhibition by ATP (IC(50) of 15 micromol/l and 38 micromol/l for wild-type and heterozygous channels, respectively) and an increase in the resting K(ATP) current. This would be expected to impair insulin secretion. The results are in agreement with the mild phenotype of the patients. CONCLUSIONS Our results broaden the spectrum of diabetes phenotypes resulting from KCNJ11 mutations. They indicate testing for KCNJ11 mutations should be considered not only for neonatal diabetes but also for other forms of dominantly inherited diabetes with later onset, especially where these are associated with a low body mass index and low birth weight.

Abstract
The optimization, through a Design of Experiments (DoE) approach, of a microencapsulation procedure for isolated neonatal porcine islets (NPI) is described. The applied method is based on the generation of monodisperse droplets by a vibrational nozzle. An alginate/polyornithine encapsulation procedure, developed and validated in our laboratory for almost a decade, was used to embody pancreatic islets. We analyzed different experimental parameters including frequency of vibration, amplitude of vibration, polymer pumping rate, and distance between the nozzle and the gelling bath. We produced calcium—alginate gel microbeads with excellent morphological characteristics as well as a very narrow size distribution. The automatically produced microcapsules did not alter morphology, viability and functional properties of the enveloped NPI. The optimization of this automatic procedure may provide a novel approach to obtain a large number of batches possibly suitable for large scale production of immunoisolated NPI for in vivo cell transplantation procedures in humans.

Abstract
BACKGROUND Polymyxin B (PMX-B) is a polycationic antibiotic, known to bind the lipid A portion of endotoxin, a cell wall component found exclusively in gram negative bacteria (GNB). An extracorporeal hemoperfusion device (TORAYMYXIN) has been developed: PMX is covalently bound on the surface of an insoluble carrier material so that the endotoxin can be inactivated in the blood without exerting its toxicity on the brain and kidney. The aim of this study was to clarify the efficacy, safety and clinical effects of direct hemoperfusion with an immobilized polymyxin-B fiber column (DHP-PMX) in solid organ transplanted patients with severe sepsis or septic shock. METHODS From June 2004 to May 2005, 15 patients (10 men and 5 women), mean age 55 years old (46-65 range), underwent kidney or liver transplantation and developed severe sepsis or septic shock, as defined by the Consensus Conference of American College Physicians/Society of Critical Care Medicine (ACCP/SCCM) criteria. GNB were detected in all the patients receiving conventional treatments including antibiotic therapy, vasopressive or inotropic agents, and ventilation support. The DHP-PMX treatment was performed three times in each patient. Hemodynamic and respiratory parameters, dosage of vasopressor/inotropic drugs were assessed at baseline and after each treatment. RESULTS No adverse events occurred. From baseline to 3rd treatment, mean arterial pressure (MAP) was increased (from 63+/-5 to 83+/-4 mmHg), while the dosage of dobutamine (from 7.5+/-3 to 3+/-2 mcg/kg/min) and noradrenaline (from 1.3+/-0.45 to 0.05+/-0.02 mcg/kg/min) were reduced. The PaO2/FiO2 ratio increased (from 234+/-38.47 to 290+/-107.48 mmHg). CONCLUSION The use of DHP-PMX in association with conventional therapy may be an important aid in patients with sepsis.

Abstract
UNLABELLED Orthotopic liver transplantation (OLT) is affected by important alterations of hemostasis. The aim of this study was to evaluate the efficacy of recombinant factor VII activated (rFVIIa) to reduce intraoperative bleeding during OLT. METHODS Twenty OLT patients were assigned in double-blind way to a rFVIIa group or a control group. Inclusion criteria were hemoglobin > 8 g/dL: INR > 1,5 and fibrinogen > 100 mg/dL. We administered a single bouls of rFVIIa (40 microg/kg) or placebo. We determined INR, partial thromboplastin time, fibrinogen, ATIII, and blood cell counts. Blood products were administered as follows: 4 units of fresh frozen plasma when INR > 1.5, and 1 unit of RBC for Hb < 10 g/dL. The study ended 6 hours after the bolus. RESULTS No thromboembolic events occurred. The INR was different between rFVIIa group and the controls at T0 (1.9 vs 1.6 P < .021) and during T1 (1.2 vs 1.6 P < .004). The total transfused red blood cells was 300 mL +/- 133 in rFVIIa group and 570 mL +/- 111 in control group (P < .017). The total fresh frozen plasma was 600 mL +/- 154 in rFVIIa group and 1400 mL +/- 187 in control group (P < .001). Total blood loss was greater in the control group than the rFVIIa group: 1140 mL +/- 112 vs 740 mL +/- 131 (P < .049). DISCUSSION The use of rFVIIa during OLT can reduce the risk of bleeding during surgery. The literature has described cases who did not benefit from the treatment. An adequate cut-off of INR, allowed us to treat only patients at greater bleeding risk.

Abstract
UNLABELLED Cerebral dysfunction may be fatal in patients with acute liver failure (ALF); intracranial pressure (ICP) monitoring may be mandatory to direct measures to prevent further cerebral edema. Recently the introduction of dialysis with the molecular adsorbent recirculating system (MARS) has improved the outcomes among patients with ALF. The aim of this study was to evaluate ICP changes after MARS treatment among patients with ALF. METHODS Three patients -- 14, 18 and 16 years old -- were admitted to the ICU for acute liver failure induced by HBV in two cases and by acetaminophen in the other one. Because of Glasgow Coma Score (GCS) <8, they were intubated and ventilated to protect the airway and maintain moderate hypocapnia. Invasive monitoring of intracranial pressure MARS treatments were performed in all patients. RESULTS The patients received MARS treatments every day after their admission to liver transplantation. After MARS therapy the ICP decreased on average from 21 to 7 mm Hg. Significant hemodynamic modifications were not observed and their neurological conditions improved. CONCLUSION MARS treatment improved the clinical pictures of these patients increasing the available time to obtain an urgent liver graft.

Abstract
Traditionally, Single Photon Avalanche Diodes (SPADs) are fabricated using dedicated processes that require additional technological steps when compared to standard CMOS. Instead, this paper presents the design of SPADs that attain good performances, by using a standard high-voltage CMOS process. The detector is monolithically integrated together with an Active Quenching Circuit (iAQC), a counter, and a serial communication interface. This opens the way to the design and fabrication of ultra compact multi-channel single-photon counters.

Abstract
BACKGROUND The allergological relevance of Ambrosia in Europe is growing but the efficacy of the injective immunotherapy for this allergen has been documented only in Northern America. OBJECTIVE We sought to study the safety and efficacy of injective immunotherapy in European patients sensitized to Ambrosia artemisiifolia. METHODS Thirty-two patients (18 M/14 F, mean age 36.78, range 23-60 years) suffering from rhinoconjunctivitis and/or asthma and sensitized to Ambrosia were enrolled and randomized in a double-blind, placebo-controlled (DBPC) study lasting 1 year. A maintenance dose corresponding to 7.2 microg of Amb a 1 was administered at 4-week intervals after the build-up. During the second and the third year, all patients were under active therapy in an open fashion. Symptom and medication scores, skin reactivity to Ambrosia (parallel line biological assay), and pollen counts were assessed throughout the trial. RESULTS Twenty-three patients completed the trial. No severe adverse event was observed. During the DBPC phase, actively treated patients showed an improvement in asthmatic symptoms (P=0.02) and drug (P=0.0068) scores days with asthmatic symptoms (P=0.003), days with rhinitis symptoms (P=0.05), and days with intake of drugs (P=0.0058), as compared to before therapy. No improvement for any of these parameters was detected in the placebo group. Moreover, the number of days with rhinitis and asthma was significantly higher in the placebo as compared to the active group (P=0.048 and P<0.0001, respectively). Patients who switched from placebo to active therapy improved in rhinoconjunctivitis, asthma, and drug intake. The skin reactivity decreased significantly (12.2-fold, P=0.0001) in the active group whereas a slight increase (1.07-fold, P=0.87) was observed in the placebo group after the DBPC phase. After switching to active therapy, patients previously under placebo showed a significant decrease of this parameter (4.78-fold, P=0.002). CONCLUSION Injective immunotherapy is safe and clinically effective in European patients sensitized to Ambrosia.

Abstract
Multiple sclerosis and celiac disease are both considered immune-mediated diseases. Recently, improved serological screening methods provided a higher prevalence of celiac disease (CD) in the general population worldwide and also demonstrated gastrointestinal symptoms may be lacking. The aim of this study was to determine the prevalence of (CD) in an unselected group of 95 adults with multiple sclerosis using transglutaminase antibodies. No patients showed pathological values. Different immune and genetic basis between the two diseases may represent crucial insights to explain our results.

Abstract
The aim of this study is to determine the role of radiographic assessment in patient who underwent an adjustable laparoscopic (or laparotomic) banding for the treatment of morbid obesity, and to evaluate the different type of postoperative complications. Forty-three consecutive patients with morbid obesity were examined before and after surgical treatment with positioning of Lap-Band. In all patients radiological examination permitted to evaluate the bend position, the dimensions of the gastric pouch and of the stoma. In such cases it was possible to modify the stoma dimensions under fluoroscopy. 74.4% of patients obtained satisfactory weight loss without complications. In 16.2% of patients the treatment was unsatisfactory and the radiological examination demonstrated the presence and the type of complications. In 9.3% of patients the radiological exam was negative for complications but they didn't obtain satisfactory weight loss. Radiographic assessments are crucial in the management of weight loss and detection of postoperative complications in this surgical treatment.

Abstract
BACKGROUND AND OBJECTIVE Hepatic toxicity directly related to the drugs administered in cyclic chemotherapy (CT), although sometimes serious, does not limit the treatment of non-Hodgkin's lymphoma (NHL). Nevertheless, reports of reactivation of viral hepatitis in NHL patients with B virus (HBV) infection are becoming more frequent. The recent observation of two cases of severe liver toxicity directly correlated to CT and a case of fatal hepatic failure due to HBV replication prompted us to evaluate the hepatic toxicity of CT in 98 consecutive B-cell NHL patients treated with relatively homogeneous cyclic CT. METHODS Acute hepatic toxicity was retrospectively evaluated in 98 consecutive B-cell NHL patients who received induction CT. HBV and HCV markers were checked at presentation. All patients were tested for ALT and bilirubin before every CT course, while tests for HBV-DNA and/or for HCV-RNA were performed with PCR only when hepatitis occurred. RESULTS At presentation 22 patients (22.4%) were positive for HBsAg, and 11 (15.9%) were positive for anti-HCV. Acute hepatitis developed in 12 (12.2%) NHL patients: 8 (out of 22) in HBsAg-positive and anti-HCV-negative patients, 3 (out of 76) in HBsAg-negative patients, and 1 (out of 11) in anti-HCV-positive patients. Hepatitis was attributed to reactivation of chronic B hepatitis in 3 patients and to drug toxicity in 3 others; hepatitis was undefined in 6 cases. INTERPRETATION AND CONCLUSIONS Drug-related liver toxicity is not a rare occurrence in NHL patients. Reactivation of HBV replication is responsible for a relevant number of the hepatitis cases observed. We did not detect acute hepatitis due to the reactivation of HCV replication (in chronic C hepatitis carriers).

Abstract
PATIENTS AND METHODS Ninety-five patients with previously untreated, advanced or unfavorably presenting Hodgkin's disease were recruited in ten centers. Twenty-five patients with stage II-A-bulky disease received four courses of EBVD (epirubicin, bleomycin, vinblastine, dacarbazine) plus involved field radiotherapy (Group 1); 24 patients in stage I-B, II-B and III-A received 6 courses of EBVD (11 of them also received radiotherapy on bulky localizations (Group 2); 46 patients in stage III-AS > or = 3 nodes, III-B and IV received MOPP/EBVD 4 + 4 courses (Group 3). RESULTS Eighty patients (84%) achieved CR, eight patients (8%) a PR, five patients did not respond and two progressed during therapy. CRs were achieved by 23/25 patients (92%) in Group 1, 21/24 (87%) in Group 2 and 36/46 (78%) in Group 3. The mean duration of follow-up was 33.3 months (range 5-69). There were three deaths from directly treatment-related causes. Twelve patients suffered chronic toxicity, including six who suffered lung toxicity and two who developed secondary myelodysplasia. CONCLUSIONS The results achieved in this co-operative study are similar to those reported by most single-Institution trials and those with adriamycin-containing regimens. Long-term toxicity deserves careful consideration.

Abstract
This study reports a case of granulocytic sarcoma that developed in the epidural zone 25 days before clinical evidence of an acute promyelocytic leukemia. The case presented the diagnostic difficulties that are common to all aleukemic granulocytic sarcomas. Moreover, it highlights the very rare association between granulocytic sarcoma and acute promyelocytic leukemia, which is far from being explained.

Abstract
Prolymphocytic leukemia (PLL) is a malignant lymphoproliferative disorder, characterized by massive splenomegaly, predominance of prolymphocytes in the peripheral blood and bone marrow, minimal lymph nodes enlargement and poor prognosis. It accounts for a 5-10% case of chronic lymphocytic leukemia (CLL). Patients age is usually over the fifth decade, the disease is 4.1 more common in males. More than 80% are B-lymphocytic derived cells showing a post-thymic phenotype. Median survival of B-PLL patients is 3 years, while only 7 months in T-PLL. Standard therapy of CLL with alkylating agents and prednisone have been not much effective in the treatment of PLL with a response rate of about 20%. Up to date no ideal treatment is available for PLL. A realistic goal is probably to achieve a clinical course transformation, from aggressive to mild, thus changing from short to long term prognosis. For this purpose the initial therapeutic approach cannot be limited to a single agent only. Splenic irradiation, intensive anthracyclines-based regimens, leukapheresis combine together represent the best therapeutic choice. Alkylating agents with or without prednisone may play a role in keeping indolent clinical course. Fludarabine has shown antileukemic activity against PPL even in patients resistant.

Abstract
A large number of drugs may interfere with the hair cycle and produce hair loss. Drugs may affect anagen follicles through 2 main different modalities: (i) by inducing an abrupt cessation of mitotic activity in rapidly dividing hair matrix cells (anagen effluvium) or (ii) by precipitating the follicles into premature rest (telogen effluvium). In anagen effluvium, hair loss usually occurs within days to weeks of drug administration, whereas in telogen effluvium, hair loss becomes evident 2 to 4 months after starting treatment. Anagen effluvium is a prominent adverse effect of antineoplastic agents, which cause acute damage of rapidly dividing hair matrix cells. Telogen effluvium may be a consequence of a large number of drugs including anticoagulants, retinol (vitamin A) and its derivatives, interferons and antihyperlipidaemic drugs. Drug-induced hair loss is usually reversible after interruption of treatment. The prevalence and severity of alopecia depend on the drug as well as on individual predisposition. Some drugs produce hair loss in most patients receiving appropriate dosages while other drugs are only occasionally responsible for hair abnormalities. Both hirsutism and hypertrichosis may be associated with drug administration. Drugs most commonly responsible for the development of hirsutism include testosterone, danazol, corticotrophin (ACTH), metyrapone, anabolic steroids and glucocorticoids. Hypertrichosis is a common adverse effect of cyclosporin, minoxidil and diazoxide.

Abstract
We report a case of idiopathic hypereosinophilia syndrome (H.E.S.) with a pronounced myeloproliferative disorder, which during the course of the illness has exceeded more than one "blastic crisis". This again proposes the difficult relationship between H.E.S. and myeloproliferative syndromes (M.S.), and is indicative of why some cases of H.E.S. are differentially diagnosed as chronic myeloid leukemia (C.M.L.) with an eosinophilic component.

Abstract
We have analyzed 263 consecutive patients with chronic-lymphocytic leukemia. They all have been studied according to five different staging systems respectively proposed by Rai (1975), Binet (1977), Binet again (1981), Baccarini (1982) and Rozman (1984). All these procedures proved to be effective, because they divided our cases in groups with significant differences in survival time. The paper displays features and usefulness of each staging system.
