Abstract

The commissioning of the VIRGO central interferometer occasioned the implementation and tests of various algorithms for the characterization of the non-Gaussianity, non-stationarity and non-linearity of the dark fringe data. This library of prototypes will serve as groundwork for the near commissioning of VIRGO (full scale). We make a summary of the activities on that subject including the description of the selected algorithms and some results obtained with the data of the engineering runs.

Abstract

The ARGO-YBJ experiment is presently under construction at the Yangbaijing High-Altitude Cosmic Ray Laboratory (4300 m a.s.l), 90 km north to Lhasa (Tibet, People's Republic of China). ARGO will study fundamental issues in cosmic ray and astroparticle physics by detecting small-size air showers. The detector covers 74 /spl times/ 78 m/sup 2/ with single layer resistive plate counters (RPCs), surrounded by a partially instrumented guard ring. The ARGO Data Acquisition System is designed around static random access memory (SRAM)-based field programmable gate arrays (FPGAs), in order to achieve a fully reconfigurable architecture. In this environment, the same hardware platform performs different functions provided by companion FPGAs' configuration files. Control and monitoring software exploits a web browser to deliver commands and perform diagnostic tests on the boards. In this paper, we describe the hardware and the software strategies that allow the ARGO DAQ to benefit from the flexible architecture of in-system reconfigurable FPGAs.

Abstract

The VIRGO Central Interferometer (CITF) is a short suspended interferometer operated with the central area elements of the VIRGO detector. The main motivation behind the CITF is to allow the integration and debugging of a large part of the subsystems of VIRGO while the construction of the long arms of the antenna is being completed. This will permit a faster commissioning of the full-size antenna. In fact, almost all the main components of the CITF, with the exception of the large mirrors and a few other details, are the same as those to be used for the full-size detector. In this paper the present status of the VIRGO CITF is reported.

Abstract

Palliative airway treatments are essential to improve quality and length of life in lung cancer patients with central airway obstruction. Rigid bronchoscopy has proved to be an excellent tool to provide airway access and control in this cohort of patients. The main indication for rigid bronchoscopy in adult bronchology remains central airway obstruction due to neoplastic or non-neoplastic disease. We routinely use negative pressure ventilation (NPV) under general anaesthesia to prevent intraoperative apnoea and respiratory acidosis. This procedure allows opioid sparing, a shorter recovery time and avoids manually assisted ventilation, thereby reducing the amount of oxygen needed, while maintaining optimal surgical conditions. The major indication for NPV rigid bronchoscopy at our institution has been airway obstruction by neoplastic tracheobronchial tissue, mainly treated by laser-assisted mechanical dissection. When strictly necessary, we use silicone stents for neoplastic or cicatricial strictures, reserving metal stents to cover tracheo-oesophageal fistulae. NPV rigid bronchoscopy is an excellent tool for the endoscopic treatment of locally advanced tumours of the lung, especially when patients have exhausted the conventional therapeutic resources. Laser-assisted mechanical resection and stent placement are the most effective procedures for preserving quality of life in patients with advanced stage cancer.

Abstract

Study objectives To compare the effectiveness of two modalities of external ventilation during rigid bronchoscopy: intermittent negative pressure ventilation (INPV) and external high-frequency oscillation (EHFO). Design Prospective, controlled, randomized, nonblinded study. Setting University-affiliated hospital. Patients Seventy patients undergoing interventional rigid bronchoscopy for tracheobronchial lesions were enrolled into the study. Interventions Mechanical ventilation was performed by INPV or EHFO. When pulse oximetry was Measurements and results Arterial blood gases were sampled preoperatively and intraoperatively. Most patients in both groups had normal intraoperative Pa co 2 (mean, 43.6 ± 11.8 mm Hg under EHFO and 37.4 ± 8.2 mm Hg under INPV; p = 0.012), and acidemia occurred in 9 of 35 patients of EHFO group and in 2 of 35 patients of INPV group (p = 0.049). Hypercapnia (Pa co 2 > 50 mm Hg) was observed in 10 patients under EHFO and in 2 with INPV (p = 0.026). Intraoperative mean Pa o 2 was similar (101.4 ± 52.9 mm Hg with EHFO and 124.2 ± 50.3 mm Hg with INPV; p = 0.07), but O 2 supply was different (3.5 ± 2.3 L/min during INPV and 8.5 ± 6.2 L/min during EHFO; p o 2 Conclusions External negative pressure ventilation appears to be a suitable choice during rigid bronchoscopy: both EHFO and INPV ensure effective ventilation and comfortable operating conditions in the majority of patients. Some patients may receive inadequate ventilation with EHFO, developing respiratory acidosis and requiring manually assisted ventilation. In comparison with INPV, EHFO requires a higher fraction of inspired oxygen.

Abstract

Study objective To evaluate the efficacy of negative pressure ventilation (NPV) in avoiding or reducing apneas and related hypoxemia and respiratory acidosis during laser therapy (LT) of endobronchial lesions. Design A prospective, controlled, randomized study. Setting An operating theater of a respiratory endoscopy and laser therapy unit. Population and intervention Twenty-seven consecutive patients referred to LT were entered into the study. Fourteen patients were randomly assigned to LT under general anesthesia and spontaneous assisted ventilation (control group) whereas in 13 cases, NPV by a poncho-wrap ventilator (NPV group) was added to the procedure. Measurements and results The prevalence and the duration of apnea/hypopnea periods assessed by respiratory inductive plethysmography during LT were significantly reduced under NPV, compared to the control group. As compared to baseline, during LT, all control patients developed mild to severe hypercapnia (PaCO2 ranging from 55 to 76 mm Hg) and respiratory acidosis (pH from 7.33 to 7.19), whereas only three patients undergoing NPV (23%) developed hypercapnia (PaCO2 from 52 to 68 mm Hg) and related acidosis (pH from 7.29 to 7.21). Optimal oxygenation was achieved in all of the patients; nevertheless, patients under NPV needed a lower mean oxygen supply; five of them (38%) could be treated at a fraction of inspired oxygen of 0.21 for the whole procedure. Conclusion NPV may be useful in reducing apneas during laser therapy under general anesthesia, thus reducing hypercapnia, related acidosis, and need of oxygen supplementation.

Abstract

A 36-year-old woman underwent left main bronchus sleeve resection for a typical carcinoid. The bronchial anastomosis was reinforced with a bovine pericardial flap fixed by fibrin glue. Six months after the surgery the patient presented with acute dyspnea. Flexible bronchoscopy disclosed an endoluminal migration of the pericardial flap through the anastomotic dehiscence and a cicatricial stenosis of the left upper bronchus. The migrated flap was successfully removed and the stenosis segment of the bronchus was dilated using a rigid bronchoscope. Two months after complete recovery from the bronchial dehiscence, the patient developed an anastomotic cicatricial stenosis, which was effectively treated by laser photoresection and mechanical dilatation. Eight months after the last procedure the patient remains symptom free.

Abstract

This paper reports the methods and tools set up in order to deal efficiently with the design of a very large and complex digital electronic system. We describe the methods set up for the purpose of granting interactivity to the design of the electronics: this interactivity allows straightforward evaluation of different scenarios as well as evaluation of different what–if choices; it finally allows interactive fine tuning of the parameters of the chosen structure. The preliminary results obtained in the early stage of this project are very promising, because they result in a friendly, interactive and fast system for debugging different design choices, allowing easy comparison and also obtaining reliable figures on the performance of the overall system, measured along large time intervals as needed and subject to operating conditions which statistically would reproduce real life conditions.

Abstract

The ARGO-YBJ experiment is mainly devoted to search for astronomical gamma sources. The arrival direction of air showers is reconstructed thanks to the times measured by the pixels of the detector. Therefore, the timing calibration of the detector pixels is crucial in order to get the best angular resolution and pointing accuracy. Because of the large number of pixels a hardware timing calibration is practically impossible. Therefore an off-line software calibration has been adopted. Here, the details of the procedure and the results are presented. (C) 2008 Elsevier B.V. All rights reserved.

27. La terapia radicale

Author

Sergio Cavaliere and Pierfranco Foccoli

Abstract

La piu frequente indicazione alla broncoscopia terapeutica e rappresentata dai tumori ostruenti la trachea ed i grossi bronchi. Nella grande maggioranza dei casi si tratta di tumori maligni non operabili in cui la rimozione della componente endoluminale ostruente oppure il posizionamento di una protesi nelle compressioni estrinseche rappresentano una terapia palliativo-sintomatica.

Abstract

Il cancro del polmone puO presentarsi all’esame broncoscopico con aspetti differenti in rapporta alle modalita di crescita della neoplasia e al modo in cui la parete bronchiale e coinvolta dal processo proliferativo tumorale. Sebbene sia da tutti riconosciuta la necessita di standardizzare la definizione descrittiva dei vari tipi di lesione con cui il cancro del polmone si puO manifestare dal punto di vista broncoscopico, ancora non e stata proposta una nomenclatura universalmente accettata. Un tentativo di classificazione dei possibili reperti broncoscopici in corso di cancro del polmone e quello proposto dalla Japan Lung Cancer Society [1] che definisce i quadri determinati dalla crescita endoluminale del tumore, quelli legati alla infiltrazione della parete o alla sua compressione e le conseguenze che tali lesioni possono determinare sulla pervieta delle vie aeree. Tale classificazione distingue le lesioni a sviluppo endoluminale come di tipo polipoide o nodulare, definendo il tumore polipoide come un tumore protrudente nel lume e mobile con i movimenti della respirazione mentre la forma nodulare e fissa durante la respirazione [1]. Quando i noduli sono piu di uno, la lesione e definita come multinodulare. Un tumore polipoide o nodulare puO avere una superficie liscia o irregolare o granuleggiante, oppure presentare aspetto necrotico. Quando il tumore si sviluppa all’interno della parete bronchiale o anche sulla superficie mucosa, ma senza aggettare nel lume, la Japan Lung Cancer Society usa la definizione di “infiltrazione”, descrivendo una serie di caratteristiche che possono essere rilevate in una mucosa infiltrata: pallore, irregolarita o perdita di lucentezza della mucosa, iperemia e arrossamento, congestione vascolare, edema, perdita del disegno cartilagineo, pieghe mucose irregolari o ispessite o indistinte oppure assenti. Sia le lesioni a sviluppo endoluminale che quelle infiltrative possono determinare riduzione del lume bronchiale con stenosi (lume ridotto ma ancora visibile) o ostruzione completa.

Abstract

We review the derivation and design of digital waveguides from physical models of stiff systems, useful for the synthesis of sounds from strings, rods, and similar objects. A transform method approach is proposed to solve the classic fourth-order equations of stiff systems in order to reduce it to two second-order equations. By introducing scattering boundary matrices, the eigenfrequencies are determined and their dependency is discussed for the clamped, hinged, and intermediate cases. On the basis of the frequency-domain physical model, the numerical discretization is carried out, showing how the insertion of an all-pass delay line generalizes the Karplus-Strong algorithm for the synthesis of ideally flexible vibrating strings. Knowing the physical parameters, the synthesis can proceed using the generalized structure. Another point of view is offered by Laguerre expansions and frequency warping, which are introduced in order to show that a stiff system can be treated as a nonstiff one, provided that the solutions are warped. A method to compute the all-pass chain coefficients and the optimum warping curves from sound samples is discussed. Once the optimum warping characteristic is found, the length of the dispersive delay line to be employed in the simulation is simply determined from the requirement of matching the desired fundamental frequency. The regularization of the dispersion curves by means of optimum unwarping is experimentally evaluated.

Abstract

The Data Acquisition system for the KLOE experiment, presently running at the Laboratori Nazionali di Frascati DAΦNE collider, has been designed to sustain an acquisition throughput of 50 Mbyte / s for an event rate of 10 kHz . Its two major components are the front end data readout, based on custom buses, and a complex network of computers and storage devices hosting a set of distributed processes. The end result is a seamless data transport from the readout system to the storage library, accompanied by concurrent on line calibrations and data quality control.

Abstract

We describe our experience in the diagnosis and treatment of idiopathic subglottic stenosis (ISS), a rare pathological entity involving the subglottic larynx and the first tracheal rings and affecting virtually only females. Its diagnosis can be made only after the exclusion of all other known causes of subglottic stenosis. In a 17-year period, between January 1986 and June 2002, 30 patients were admitted and treated for ISS at the Department of Otolaryngology and/or the Center for Respiratory Endoscopy and Laser Therapy, the University of Brescia, Italy. Clinical, endoscopic and surgical records were retrospectively analyzed with particular emphasis on treatment (endoscopic versus open-neck procedures) and follow-up. Based on our experience, we can define endoscopic treatment by carbon dioxide or Nd:YAG laser-assisted dilatation and scar tissue resection with or without airway stenting as the treatment of choice for the initial management of ISS. After repeated endoscopic failures, open-neck surgery by laryngoplasty or laryngotracheal resection and anastomosis is strongly recommended, particularly for complex lesions longer than 1 cm.

Abstract

A data acquisition system for a real time large scale application (more than 30,000 acquisition channels) has been developed. This required the design of two custom busses (AUXbus and Cbus), a readout controller (ROCK) and a read-out controller manager (ROCK manager). A crate containing a VME CPU, a ROCK, (1-16) front end slave boards and an Auxbus backplane comprise one DAQ sub-system. The ROCK performs data acquisition in a event-driven fashion on the AUXbus, a custom high speed parallel bus. The AUXbus's main features are data cycles labelled by event number, sparse data scan operations and an asynchronous protocol optimised to achieve random length block transfers at data rates up to 15 MHz. Up to 8 of the above described DAQ sub-system crates can be linked together via the Cbus in a daisy-chain fashion to the ROCK manager, to form a complex DAQ system. The ROCK manager performs event driven data acquisition in a token passing fashion on the Cbus. The Cbus's main features are data cycles labelled by event number and random length block transfers at 10 MHz. A preliminary version of the DAQ system is presented and test results are briefly discussed.

Between June 1983 and December 2002, 32 patients were treated for primary localized laryngo-tracheobronchial amyloidosis (LTBA) at our institution. For enrollment in this retrospective study, at least one positive biopsy with Congo red stain and a diagnostic test battery excluding systemic or secondary amyloidosis were mandatory. The most common presenting symptom was dyspnea, which was observed in 75% of cases. Endoscopic appearance was described as submucosal plaques and nodules with a cobblestone appearance in 44% of patients, tumor-like in 28% and circumferential wall thickening in 28% of cases. Tracheobronchopatia osteochondroplastica was associated with LTBA in 22% of patients, both at the first treatment (four cases) or during follow-up examinations (three). Synchronous or metachronous disease in the larynx and tracheobronchial tree was observed in 47% of cases, while only one patient showed lung involvement with extensive amyloidosis of the trachea and bronchi. All but two patients were endoscopically treated. One of these was affected by a tracheal amyloidoma cured by endoscopic debulking and further tracheal resection-anastomosis. The other patient presented massive laryngo-pharyngeal involvement and was therefore treated by total laryngectomy. A total of 58 endoscopic procedures (range: 1-7; mean: two per patient) were carried out, 11 with CO2 laser (for supraglottic, glottic and selected subglottic lesions) and 47 with Nd:YAG laser (for the most part of subglottic lesions and amyloid deposits located in trachea and bronchi). Four patients required a tracheotomy and three necessitated a T-tube stent during management, which was subsequently removed in all cases. One patient was lost to follow-up, nine were endoscopically controlled elsewhere (Group A) and 22 were followed at our institution (Group B). In Group A, the patient with tracheal amyloidoma is asymptomatic and free of additional LTBA localizations 8 years after surgery. The remaining eight are asymptomatic, but with persistent endoscopic signs of amyloidosis. In Group B, five patients died: one from heart failure and another one from pneumonia 3 and 4 days after surgery, respectively. In one case death was from unrelated causes, and in the two remaining patients it was from respiratory failure due to uncontrolled bilateral bronchial amyloidosis in the subsequent 5 to 6 years. One patient is completely cured 5 years after surgery, and 16 are asymptomatic with persistence of LTBA.

Abstract

The VIRGO suspensions are chains of passive mechanical filters designed to isolate the interferometer mirrors from seismic noise starting from a few Hz. In order to reduce the low-frequency swing of the mirror along the beam, an active control system, acting at the level of the suspension point, damps the main resonant modes of the system (all below 2.5 Hz). Another control loop, at the level of the optical payload, makes use of a digital camera monitoring the mirror position in all six degrees of freedom. Its main goal is to decrease the rms angular displacements of the mirror, on a time scale of several minutes, down to less than 1 μrad. All the seven suspensions of the VIRGO central interferometer are presently in operation, while the assembly of the last two, for the terminal mirrors, is in progress. The design and performance of the system are described in this paper. PACS number: 0480N (Some figures in this article are in colour only in the electronic version)

Abstract

The automatic control of the suspended mirrors is a major task in operating an interferometric gravitational wave antenna. To reach the extreme sensitivity required for this kind of detector, an accurate alignment and a stable locking of the interferometer on its working point are crucial. The solution of this problem is particularly complex in the case of a multistage pendulum, such as the suspension system for seismic isolation adopted in VIRGO. A precise knowledge of the suspension mechanical transfer functions (TFs) for different forces applied in the control servo-loops represents essential information to reach the goal. In this article, we describe the apparatus we developed to measure the VIRGO suspension TF and we report the results thus obtained on full-scale suspensions at the VIRGO site. Preliminary results for the implemented control system of the last suspension stage are also presented.

Abstract

We illustrate the mathematical background and musical use of a class of audio effects based on frequency warping. These effects alter the frequency content of a signal via spectral mapping. They can be implemented in dispersive tapped delay lines based on a chain of all-pass filters. In a homogeneous line with first-order all-pass sections, the signal formed by the output samples at a given time is related to the input via the Laguerre transform. However, most musical signals require a time-varying frequency modification in order to be properly processed. Vibrato in musical instruments or voice intonation in the case of vocal sounds may be modeled as small and slow pitch variations. Simulation of these effects requires techniques for time-varying pitch and/or brightness modification that are very useful for sound processing. The basis for time-varying frequency warping is a time-varying version of the Laguerre transformation. The corresponding implementation structure is obtained as a dispersive tapped delay line, where each of the frequency dependent delay element has its own phase response. Thus, time-varying warping results in a space-varying, inhomogeneous, propagation structure. We show that time-varying frequency warping is associated to an expansion over biorthogonal sets generalizing the discrete Laguerre basis. Slow time-varying characteristics lead to slowly varying parameter sequences. The corresponding sound transformation does not suffer from discontinuities typical of delay lines based on unit delays.

Abstract

BACKGROUND Ventilation during interventional rigid bronchoscopy (IRB) under general anaesthesia (jet ventilation, positive pressure ventilation and spontaneous assisted ventilation) may offer some difficulties. This study compares the effectiveness during IRB of intermittent negative pressure ventilation (INPV) and spontaneous assisted ventilation (SAV). METHODS Thirty-eight patients submitted to IRB were randomised into two groups: SAV or INPV. All patients received a total intravenous anaesthesia; INPV patients were paralysed. Pre- and intra-operative arterial blood gases and O2 flow through a rigid bronchoscope were assessed. The endoscopist applying a subjective score evaluated the operating conditions. RESULTS Patients of the INPV group, as compared to the SAV group, required a lower dosage of fentanyl (2.6 +/- 1.8 micrograms.kg-1.h-1 vs. 6.6 +/- 4.8 micrograms.kg-1.h-1), a lower O2 supply (3.3 +/- 2.8 l/min vs. 11.6 +/- 3.4 l/min), a shorter recovery time (5.4 +/- 2.9 min vs. 9.8 +/- 7.1 min) and no manually assisted ventilation (0 +/- 0 vs. 1 +/- 1.1 n degree/procedure). Intraoperative PaCO2 was higher in the SAV (8.1 +/- 1.3 kPa) than in the INPV group (5.0 +/- 1.6 kPa) and intraoperative pH differed in the two groups (7.26 +/- 0.05, SAV vs. 7.47 +/- 0.08, INPV). Operating conditions, as assessed by a subjective score, were considered better with INPV than with SAV (4.9 vs. 4.3). CONCLUSIONS As compared to SAV, INPV in paralysed patients during IRB reduces administration of opioids, shortens recovery time, prevents respiratory acidosis, excludes the need for manually assisted ventilation, reduces O2 need and affords optimal surgical conditions. INPV appears a safe, non-invasive and effective ventilatory management during IRB.

Abstract

We report our 13-year experience with endoscopic treatment of malignant obstructions of the airway by Nd:YAG laser, stents, and intraluminal brachytherapy in 2,008 patients. We performed 2,610 laser resections in 1,838 patients, 66 high dose rate brachytherapies, and we placed 393 tracheobronchial silicone stents in 306 patients. We used the rigid bronchoscope in 96% of the laser procedures and in all cases requiring stent placement; general anesthesia was given to 90% of these patients. Endobronchial radiotherapy was performed under local, anesthesia. In 93% of patients undergoing laser resection, we obtained an immediate patency of the airway with consequent improvement of quality of life. The median time between the first and second laser treatment was 102 days, being longer in the case of stent placement (when required) or in association with brachytherapy. Even if endoscopic treatment should be considered only for palliation, laser vaporization could be curative in case of in situ carcinoma. Since 1983, we have treated 23 such lesions in 17 patients and up to now, none has recurred. Finally, endoscopic resection may allow a better assessment of the true extent of the tumor, shifting to surgery patients originally considered to have inoperable disease or allowing lung-sparing operations (21 and 18 patients of our series, respectively). The total mortality rate was 0.4% (12 patients over 2,798 treatments; 2,710 Nd:YAG laser + 151 stents without laser + 37 brachytherapies without laser) in the first week after the procedures, and was mainly related to cardiovascular problems and respiratory failure. In conclusion, endoscopic resection of lung malignancies is rapid, effective, repeatable, and complementary to other treatments; although it should be considered only palliative, laser resection could be curative in patients with in situ carcinomas and early cancers. Laser, stents, and endoluminal brachytherapy should be available in all centers with major experience; a well-trained team is mandatory to plan the most appropriate treatment and manage any possible complication.

Abstract

The treatment of tracheo-bronchial diseases with rigid bronchoscopy requires general anaesthesia without tracheal intubation. Spontaneous assisted ventilation is a safe modality of ventilation. In this study the use of remifentanil and fentanyl is compared during rigid bronchoscopy with spontaneous assisted ventilation. Ninety high-risk patients received fentanyl or remifentanil with propofol for general anaesthesia. During the maintenance fentanyl was delivered at 6.1 +/- 4.6 micrograms kg-1 h-1 and remifentanil at 0.15 +/- 0.07 microgram kg-1 min-1. The same degree of intra-operative respiratory acidosis with similar good operating conditions resulted in both groups. Patients treated with remifentanil recovered more quickly compared with those in the fentanyl group (3.8 +/- 2 vs. 10.4 +/- 9.2 min, P < 0.001). In conclusion, the use of remifentanil during rigid bronchoscopy under general anaesthesia with spontaneous assisted ventilation is safe and assures good operating conditions. Moreover, remifentanil permits a more rapid recovery than fentanyl. The dose of remifentanil is higher than previously described for spontaneously breathing patients.

Abstract

A read-out controller (ROCK) has been developed for the Data Acquisition System of the KLOE High Energy Physics experiment, based in Frascati, Italy. The ROCK performs data acquisition in an event-driven fashion on the AUXbus, a custom high speed parallel bus. The AUXbus`s main features are data cycles labeled by event number, sparse data scan operations and an asynchronous protocol optimized to achieve data rates up to 15 MHz. On a standard VMEbus, the ROCK allows for data snooping and real-time performance monitoring, without additional overhead on data acquisition. ROCK boards can be linked together via a custom cable bus (Cbus) to build a complex DAQ subsystem. The ROCK board has been designed around three 4.2 K gate XILINX FPGAs. Dual port FIFO banks are used to decouple the asynchronous buses. A preliminary version of the board is presented and test results are briefly discussed.

Abstract

We treated 1,000 patients with the Nd:YAG laser. The rigid bronchoscope was used in 1,280 (92 percent) of the treatments, with patients almost always under general anesthesia; 116 (8 percent) treatments were performed with the flexible fiberoptic bronchoscope alone, with the use of local anesthesia. In almost all cases of benign tumors and in many carcinoid tumors, the treatment was curative. In genuine nonmalignant tracheal stenoses, laser therapy was curative in 34 out of 81 cases. In malignant tumors, the laser improved airway gauge 92 percent of the time. Cumulative survival was 50 percent (±3 percent) at six months and 26 percent (±3 percent) at one year. Following palliative laser therapy, eight patients with bronchogenic carcinoma appearing to be inoperable did have surgery and ten underwent less extensive surgery than expected. Results confirm the usefulness and safety of this relatively new method in the treatment of obstructive lesions of the tracheobronchial tree.
